31 Days of Derek Hale

Hello!

For the month of October, I've decided to write a TF story involving everyone's favorite werewolf, Derek Hale!

This is being done for a few reasons:

The most important is that Derek was done dirty in that horrible movie.

Tyler Hoechlin is my future ex-husband.

I love October!

I hope you all enjoy this as much as I've enjoyed putting it together!

31 Days of Derek Hale

Day 01: Headshrink

Info │ 01

Alpha werewolf Derek Hale stalked into the decrepit room where Stiles was hiding. He eyed the human curiously, wondering why Stiles was staring intently at some old looking book, only to wave his hands sporadically at an empty Coke can.

Stiles sharply exhaled through his nose and then shot one hand forward, gritting his teeth with the movement.

Nothing happened.

“Damn it,” the human cursed to himself.

“What are you doing?” Derek asked, trying to hold back his smirk. He kept his usual scowl plastered onto his face to hide his deep admiration for the hyperactive human.

Stiles jerked back and then blushed when he saw the werewolf eyeing him. “Um,” he muttered quietly, rubbing the back of his neck nervously, “Deaton said that he saw a ‘spark’ in me, so I’ve been trying to test it.”

Derek let his tough guy façade crack for a moment, his bushy eyebrows rising in surprise. “Really?” he pressed, taking a step forward, leaning in so close to Stiles that he could smell his cologne. “I used to have a pack member who had a spark. Maybe I can help you?”

Stiles’s face broke out into a large smile, making Derek’s heart flutter. “That’d be great!” Stiles practically cheered. He leaned in closer to the werewolf, showing off the spell book that he’d been studying. “I’m trying to use this shrinking spell to make the can smaller.”

Derek tensed up at the closeness, unconsciously leaning in even closer to the human, nearly engulfing him in his bulk. Although he denied it outwardly to anyone who asked, Derek had a serious thing for Stiles, and after years of repressing it, their physical closeness was too tempting to ignore. Hence, Derek leaned as close to Stiles as he could, glancing over his shoulder at the book.

“Just focus your mind on what you want to shrink,” Derek breathed, so close to Stiles’s ear that his breath wafted over the human’s face. He smirked when he saw Stiles’s skin break out in goosebumps.

Stiles gulped. “O-okay,” he stammered.

Derek couldn’t help but preen at the effect he was having on Stiles, so he decided to up the ante. He leaned in even closer, his stubble brushing up against his face. “Focus on the image in your mind,” he whispered, his lips so close to Stiles’s cheek that he could just give one little—

POOF!

Derek felt like the room was spinning, as if it were on some sort of hydraulic system. He stumbled back, his vision full of stars. Once it cleared, he stared up at Stiles who only gazed back with wide, stunned eyes.

“What happened?” Derek asked, flinching when he heard his voice. It had shot up several octaves, sounding like he was some cartoon chipmunk. Derek made a move to clutch at his throat in surprise, but froze when he looked at his hands, which now seemed to be the size of dinner plates. His hands were massive; and when he frantically looked around at the rest of his body, the rest of him was just as large. His pecs appeared to jut off unbelievably far in front of him and his shoulders were crazily broad.

Stiles paled, but then quickly grew red. “Um, well I guess I can shrink stuff after all?” he cheekily muttered.

“Shrink?” Derek demanded in his squeaky voice. “I’m huge! What are you talking about?”

Stiles bit down on his lip and held out his phone for a second, taking a quick photo before turning it around for the werewolf to see.

Derek’s stomach fell when saw that his body hadn’t grown, his head had shrunk. Instead of its normal size, his head was now about the size of a baseball, looking comically tiny atop his muscular frame. “You were supposed to shrink the can!” Derek growled, his squeaky voice completely eliminating any threatening tone to his words. “Not my head!”

Stiles held his hands up in front of himself in surrender. “You told me to focus on an image in my head, and then you kissed me!” he blurted. “So… unfortunately, I thought of you.”

Derek just smoldered, irritated that the very second he made his move, his head shrank. “Just turn me back then!” Derek huffed.

“Y-yeah! Totally!” Stiles said as he frantically flipped through the magic book. “Just gimme a sec, and then we’ll have you back to normal. I mean, hey, if you want, I can also make something else bigger on you too?” He eyed the werewolf knowingly, offering a playful smirk.

Despite Derek’s irritation, he couldn’t help but feel his shoulders relax the smallest bit. “After you fix my head,” he agreed. “And only if I get to try its new size out on you.”

Stiles flipped through the book at a much faster pace.

Day 02: Microdicked Bodybuilder

Info │ 01 │ 02

“Derek?” Stiles called out as he wandered through the crowded backstage. He and Derek had been investigating a trickster who was making trouble in Beacon Hills. For some reason, the trickster had decided to hide out at a bodybuilding competition. Wanting to expel the mischievous creature from their territory, Derek and Stiles had decided to ambush the trickster at said competition.

However, due to the large crowd of muscled up, barely clothed men, Stiles lost sight of Derek and the two had gotten separated.

“Derek!” Stiles yelled out again, scanning the crowd for his boyfriend. He’d wandered backstage where a lot of the large musclemen where working out to get one last pump before they hit the stage, their massive bulk only clothed by the skimpiest of posers that were available.

The small human was at least half the size of the men backstage, and he drooled over a few of their vast forms… and a part of him secretly wished that Derek would look into bodybuilding.

“Stiles!” Derek’s deep voice bellowed out, making Stiles perk up.

“Derek? Where are you— holy crap!” Stiles gasped the second his eyes landed on his boyfriend.

Or what used to be his boyfriend.

The Derek that stood before Stiles was nearly three times his normal size. All of his muscles had been crazily inflated to rival those of the other men. Derek’s legs were so thick that they pushed against each other and caused him to stand almost bowlegged. His waist was thick, his abs visible yet slightly distended to show off the beginnings of a sizable roid gut. Pecs were so large and cumbersome that they blocked Derek’s view of anything below them. His shoulders were much broader than they should’ve been, and the arms attached to them were thick with muscle and they rested upon flaring lats. Derek was clad in just pair of posers like every other bodybuilder backstage. His was a silver pair that slipped between his muscled up booty, while the pouch concealed his meager meat.

Stiles nearly chocked on his breath at the sight of Derek’s tiny junk that created a small bulge that rested in front of the new bodybuilder’s wide quads. It was hilariously tiny, looking way smaller than it should’ve been.

“Derek!” Stiles gasped, unable to take his eyes off of his boyfriend’s big/small physique. “What the hell happened to you?!”

Derek only gave an uncharacteristically wide smile as he lifted a dumbbell with one hand, the motion causing his bowling ball-sized biceps to flex with masculine power. “I’m getting my pump on,” he grinned before scrunching up his eyebrows with concern at the look of Stiles’s frantic expression. “What’s wrong? Is someone bothering you?” At that, Derek bared his werewolf fangs and let out a low growl as he puffed out his massive pecs with power.

Derek took a protective step towards Stiles, wrapping a thick arm around the small human’s waist.

At first, Stiles was so turned on that he swooned and couldn’t help but rest a hand atop Derek’s inflated chest, noting that it was slick with posing oil. “Um, n-no,” he stammered, “it’s just that… you’re huge!” He gestured at Derek’s blown up body with exasperation, unable to grasp why Derek wasn’t freaking out.

Derek’s serious face fell and he grinned widely again. “You’re just noticing?” he guffawed, letting go of his boyfriend’s waist to lean forward, forming a most muscular pose. The muscles in his arms and chest popped spectacularly, bulging with such raw power that Stile grew hard a little. 

At Stiles’s awed expression, Derek straightened up only to throw both of his huge arms above his head to form a double biceps pose. 

“I’m gonna win first place,” he beamed with pride. “No one’s muscles are larger than mine!”

“I, uh, I see that,” Stiles drooled, feeling incredibly turned on by how large Derek was. But that also alerted him to something else that was drastically out of place. Stiles lowered his voice as he whispered to his boyfriend, “B-but your cock is… uh—”

“Two and half inches?” Derek said loudly, almost with pride. “Who cares about that little thing when I have an almost eighty inch chest?” To illustrate his point, Derek bounced his muscletits, the large mounds lifting and slamming back down onto his chest.

“I mean, I guess it is hard to argue with that…”

“And besides,” Derek chuckled, leaning in closer to Stiles so that his nearly flat pouch rested on his leg, “it’s better this way since no one else can tell that I’m rock hard as I pose for you.” Derek swiveled his hips, grinding his tiny nub against Stiles.

It was difficult to tell due to its pathetic size, but Stiles was able to feel that Derek was rock hard. His small cock barely tented out the pouch of the poser thanks to how little it was, but Derek didn’t seem to mind at all.

Before Stiles could try to argue some more or try to convince Derek to find the trickster to reverse whatever spell it had obviously cast upon him, the PA speaker blared out: “Next to the stage is newcomer Derek Hale, competing in the Super Heavyweight Division!”

Derek perked up, excited. “Wish me luck!” he gushed, leaning in quickly to peck Stiles on the cheek before waddling away towards the stage entrance. His thighs were so thick that they rolled over each other, seriously hindering his movement. For a moment, Derek paused and cocked his eyebrow in confusion, feeling like something was wrong.

However, he turned back to glance at Stiles and couldn’t resist flexing a large bicep for the smaller man. The way Stiles’s eyes widened caused his cocklet to go rigid, throbbing with want. However, it was nearly swallowed by his inflated thighs, barely noticeable as he waddled out onstage to flex for the cheering crowd.

Day 04: Hypnotized

Info │ 01 │ 02 │ 03 │ 04

At Peter’s behest, Derek had begrudgingly agreed to start seeing a therapist to help him deal with some of his anger issues. At first, the werewolf was dead set against talking to some random stranger about his life, yet once he’d actually met Dr. Callahan, the therapist had somehow managed to get Derek to lower his walls. Dr. Callahan got Derek to feel extremely relaxed in his office and open up, leading to the stud to being all ears whenever the older man spoke. The therapist clearly knew his stuff, because almost overnight, Derek could feel his mood lifting and his thoughts refusing to drift towards anything that would piss him off. He would instead spend his days in an almost giddy haze, smiling happily as he went about his work and hobbies, completely unbothered. 

Derek felt like his life had changed for the better, all thanks to Dr. Callahan.

Still, every now and then, Derek would feel a little confused whenever he’d be going about his day, and tons of guys would keep staring at him. It wasn’t the fact that they were staring that was so weird, it was the fact that Derek loved them staring.

When all eyes were on him, the werewolf couldn’t help but bask in the warmth that the mens’ gazes brought him, leading to him either flexing his massive arms or unbuttoning his shirt for them.

Speaking of shirts, Derek would usually have to force himself to wear one… or really anything at all. The thought of wearing clothes was so constricting to the young man, and he loathed the idea of covering his large muscles with any sort of fabric. There were numerous times when he’d be out in public, and it would take him a good deal of time to realize that he’d been wandering around town without a shirt on, letting his plump chest muscles be on full display. After a bit of shopping, Derek had eventually changed his wardrobe so that it consisted of nothing but skintight, synthetic material that hugged his massive muscles tantalizingly. His shorts never went past mid-thigh, and he refused to wear underwear, allowing his perpetually hard cock to press against the front nonstop. And all of his shirts (a total of three since he hated to wear them) were so small that they were more like crop tops, never passing his belly button and always having the collar so low that his pecs frequently spilled out of them. Whenever he went out, Derek was sure to attract loads of lustful stares from men.

And Derek took full advantage of the lustful staring, bedding man after man.

Not a night went by when Derek wasn’t bouncing on some guy’s dick or sucking a guy off— sometimes at the same time. The werewolf was nearly insatiable now, constantly thinking about dick or drooling over a guy who would wander into his line of sight. It wouldn’t be long before Derek would approach him, flex a bit and playfully flirt, before the two would go find a private location. Or sometimes it didn’t even have to be private. There were a few times at the local gay bar where Derek would get loudly fucked on the dancefloor by a line of guys, feeling incredibly turned on by the fact that many other men were watching.

All in all, Derek’s life had done a complete one-eighty for the best, and Derek had Dr. Callahan to thank for that. Every night when he’d go to bed and place his headphones on over his ears to listen to the tapes his therapist had made just for him, he’d dreamily smile and be extremely thankful that he’d listened to Peter and had attended Dr. Callahan’s hypno therapy sessions.

“You’re a dumb muscleslut,” Dr. Callahan’s quiet voice murmured underneath the soothing wave sounds of the relaxation session Derek listened to. “All you’re made for is showing off your muscles and fucking. You’re just a dumb muscleslut…"

Day 05: Cursed Tape

Info │ 01 │ 02 │ 03 │ 04 │ 05

“Der!” Stiles voice rang out, dripping with jubilation. “Come see what I just scored!”

Derek grunted as he got out of his chair, feeling tired from his long day at the auto shop. Still, he shuffled down the hall, clad in only his white tank top and sweatpants, freezing when he saw Stiles beaming ear to ear and holding a large cardboard box.

Before he could even ask, Stiles rushed out, “I got a mystery box at the thrift store! Can you believe it?! How cool is that?”

“Mystery box?” Derek grunted, crossing his arms in front of himself as he cocked his eyebrow. “And how much did that cost?”

Stiles shrugged as he carried the box to the living room. “…um, about eighty dollars, give or take…”

Derek’s eyes widened and his jaw clenched.

Stiles obliviously set the large box down onto the floor before eagerly tearing into it, his large eyes alight with wonder over the “treasures” he’d scored for one-hundred thirty dollars. The big box was stuffed full of various items: scraps of fabric, old porcelain figurines, and some VHS tapes.

“We don’t even own a VCR,” Derek grunted, unamused. 

Among the pile that his husband was creating, Derek spotted an odd looking VHS tape. There was a gaudy neon background that looked like it was ripped straight of the 80s, with little captions indicating that it was a workout video of some kind. However, the weird part was that there was a blank outline of a person on the front instead of some obscure fitness guru. The title of the odd tape read out: Sweatin’ it to the 80’s! Starring _____!

“What the hell?” Derek scoffed as he picked up the tape to examine it some more— the second his fingers grazed the cover of the tape, Derek felt what seemed like a jolt of electricity ripple throughout him.

The werewolf jerked back, confused over what had just happened, yet he quickly realized that he was still holding onto the tape. Derek tried to relax his grip to let go of it, but his hand refused to listen, instead clutching onto the tape with all of its strength.

“Stupid tape…” he grumbled to himself, stopping once he saw something else start to happen.

Steadily, his white tank top began to change hue, turning from bleached white to a neon blue. As the straps thinned out, the collar dropped down low to his midsection, exposing his pecs to look more like a stringer. 

The changes didn’t stop there.

Stunned silent, Derek’s jaw dropped as he witnessed his toned pectorals shudder before pushing out as they gradually inflated. The previously proportional mounds plumped up and rounded, becoming an impressive set of muscletits that jutted off Derek’s chest noticeably. His altered tank did nothing at all to try to conceal them, the enlarged nipples poking out of the sides and demanding attention. His arms packed on more muscle, becoming large and bulging, especially his biceps which rivaled melons. Derek looked down, yet his massive pecs blocked his view of his sweatpants as they tightened against his legs, suctioning to his form to become a skintight pair of spandex that showed off every ridge of his carefully crafted musculature— that was prompt ruined as his legs grew in size, becoming larger. His butt ballooned out as it beefed up and pushed itself outwards. Derek’s eyes widened as he felt a sensation like he was getting harder. When he reached down and patted at his bulge, he almost gasped at the girth package that filled his hands. His cock and balls had inflated to the point where it looked like the larger stud was smuggling a softball in the front of his spandex pants.

When he was done changing, Derek had to have packed on at least fifty pounds of muscle, making him look like some over-the-top workout guru who belonged on the front of those cheesy exercise tapes.

Derek’s face stretched out to form a large grin, despite the panic that he was feeling. The living room shifted and Derek felt as if he were falling, the walls of the room stretching upwards. Derek’s sight rapidly shifted upwards, forcing him to stare straight up at the ceiling. He tried to look away or call out to Stiles for help, but he couldn’t move. All the shocked werewolf could do was smile and show off his hairy muscletits on the cover of Sweatin’ it to the 80’s! Starring Derek Hale!

Blissfully unaware of his husband’s transformation, Stiles finally finished rummaging through the mystery box. “See?” he smiled, standing upright. “There’s tons of cool stuff in here… Derek?”

Stiles looked around for Derek, pausing when his eyes landed on an obscure VHS tape that was on the floor. He walked over and picked it up, his eyebrows rising at the image of a muscled up Derek on the cover, smiling widely. His eyes looked panicked though.

“Derek!” Stiles gasped, clutching the tape close to him. “Don’t worry! I’ll figure something out!” He sprinted out of the house and to his Jeep…

About an hour later, Stiles returned home and set up the VCR in the living room. Once it was connected, he popped the cursed VHS in and pressed Play.

Synthpop blasted over the speakers, and bright neon colors flashed on the screen before a shocked Derek appeared on screen. He was still in his muscled up body, appearing to jog in place.

“Stiles?!” Derek called out on the TV, able to see his husband on the other side. He tried to stop himself from jogging, blushing at how the motion made his inflated pecs bounce up and down. “What the hell happened— Time to get that heart rate up!” His eyes widened at his last statement, having said it was such pep that he sounded like a cheerleader.

Stiles threw his hands up in exasperation.

“How am I supposed to know?” he cried. “How the hell did you get into the TV?”

Derek rolled his eyes as he stopped and started to do lunges. “It’s that damn mystery box of yours!” he accused. “I touched some weird tape and this happened!” He nodded down at his inflated form, wincing as he couldn’t stop working out.

He paused his lunges and started to bounce his pecs up and down.

“And one, and two…” He blushed, but he couldn’t stop the muscled mounds from lifting and slamming back down. Still, he was smiling widely and speaking with immense enthusiasm. “You gotta do lots of reps if you wanna get pecs as big as these!”

Derek couldn’t stop himself from working out and showing off his out of proportion body. The whole time he kept smiling, despite his eyes looking wide and disbelieving.

Stiles, unsure of what to do, figured that perhaps the best course of action was to let the video finish. Plus, he had to admit that Derek looked pretty hot with big, hairy pecs. “Um, maybe… maybe we should just let this play out?” he suggested.

Derek screamed on the inside, but could only place his hands on his hips. “Now that we’re all warmed up,” he beamed, “I’m gonna show y’all some glute blasters!”

Day 06: FaceApp

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06

Stiles giggled to himself as he messed around with FaceApp on his phone, playing with a picture of his boyfriend, Derek. He’d decided to occupy his time while waiting on the bed as Derek finished getting ready for their date night by playing around with random apps.

Stiles had taken a photo featuring Derek’s trademark scowl, and was having a great time playing with the lighting and some of the features. When he saw an ad for the premium edition, offering “Magical Changes”, Stiles shrugged and paid the $2.99.

A plethora of extra photo manipulation options popped up on screen, including a makeup section.

“‘Magical Changes’?” Stiles snickered as he clicked the makeup option…

Derek spritzed some of his cologne on as he got ready for his and Stiles’s date night. The werewolf pulled on a white button down shirt, leaving the top few buttons undone to let the cleft of his manly pecs be showcased. He looked like a total man’s man, and as he finished getting ready, Derek gave himself one last look in the mirror.

“Huh?” he wondered aloud as it looked like he was puckering his lips.

Then his eyes widened as his lips gradually inflated, becoming plump and more full as if he’d had some filler. His lips went from thin to a nice set of DSLs before a shimmering substance coated itself over them. The stunned Derek was helpless to do anything except watch as his lips turned pink and glossy, makeup somehow appearing all over his masculine face. His eyelashes lengthened as mascara was applied, and slight eyeshadow formed on his orbitals.

Derek went from looking tough and manly, to pretty and made up.

“What the fuck?” Derek panicked as he stared at his made up face in the mirror. He turned on the hot water at the sink and scrubbed at his face with soap, but no matter how hard he rubbed, the makeup remained. “I can’t go out looking like this!”

The alpha was humiliated at the thought of going around Beacon Hills wearing lipstick and eye shadow, complete with plump lips. His heart raced in his chest as he wondered what was going on…

“Hmm,” Stiles hummed as he continued to play around with his phone. Despite thinking that Derek did look pretty with the makeup filter, it didn’t really suit him too well. He cleared the filters and decided to start anew when a magnifying glass icon caught his eye…

“What the fuck was that?!” Derek huffed as his face changed back to normal in the blink of an eye. The makeup had completely disappeared and his lips were back to their normal size.

The werewolf rubbed at his eyes as if they were just playing tricks on him, which they must’ve, since when Derek examined his reflection, his face looked normal. That was until he felt his ears tingled slightly.

Derek gasped loudly as both of his ears seemingly pulled away from his head, steadily growing larger. They flapped a little outward so that they were forward-facing, giving the shocked Derek a full view of his massive ears that made him look like Dumbo. They were hilariously big, jutting out from his head at a severe angle.

Next, the werewolf nearly went cross-eyed as he watched his nose pack on more size. It wasn’t like a Pinocchio-growth, instead the whole nose packed on size to become larger, taking up more of his face as it jutted further out.

Before long, Derek had a large set of ears and a massive nose that made him feel like he was staring into a funhouse mirror instead of his bathroom mirror.

“What’s happening to me?!” Derek cried out as he grasped at his huge ears in a panic, wondering why his face kept changing…

Stiles could barely contain his hysterics at the silly picture of his boyfriend on his phone. He was about to call it quits when he saw another set of filters: Impressions.

Altering clearing the current filters, Stiles selected the folder and scrolled through the numerous options before finding an interesting one simply labeled “Giga-Chad”…

Again, Derek’s altered face snapped back to normal— his ears and nose deflating to their normal size, giving the werewolf a temporary sense of relief. He kept a cautious eye on the mirror lest his face start to change some more, but as more time passed, Derek breathed out a sigh of relief.

“Maybe I’m just losing my mind…” he trailed off, his eyes widening at the deep baritone to his voice. His voice sounded like it was several octaves deeper, sounding much more masculine than intended.

It was then that Derek watched his lower jaw shift and start to pull outwards. As it grew longer, it also widened significantly, giving the werewolf’s face a squared appearance. A deep cleft formed in his jaw as well, giving it a noticeable dimple. Cheekbones became more pronounced and Derek’s stubble gradually darkened.

“I… uh, I g-guess this look’s not too bad,” Derek muttered in his deeper voice as he ran a shaky hand over his widened jaw…

Stiles nodded with satisfaction over his handy work and pressed “Save” on the app, figuring that he’d show Derek later for a good laugh. He pocketed his phone and sighed as he waited for Derek to finish getting ready, starting to get impatient.

“Der?” Stiles called out. “Are you ready yet?”

“Um, coming!” Derek called out, yet his voice sounded much deeper than usual.

“Are you getting sick?” Stiles asked, concerned at the sound of Derek’s voice. He got off the bed and walked over to the bathroom, pausing at the sight of his altered boyfriend.

Derek was dressed up in his white button down shirt that showcased his muscles perfectly, and his slacks did little to conceal his massive bulge. Yet, most of the focus was his manly square jaw and high cheekbones. The dimpled chin was covered in manly stubble, oozing masculinity.

“How do I look?” Derek asked cheekily in his deep voice, gesturing at his face. “Wait— what are you doing?”

Stiles was already unbuttoning his pants, getting ready to ride the new Giga-Chad all night long.

Day 07: Dad Bod

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07

After moving into a new neighborhood to raise his young son, Eli, Derek made the conscious decision to attempt to be friendly… at least for his son’s sake. No matter how much the werewolf hated people, he didn’t want his son to grow up friendless due to his father’s cold attitude.

Hence, Derek started to go to PTA meetings and even Parents’ Night at Eli’s school, forcing a smile onto his face whenever he had to socialize with other parents. It worked, and Derek became a hit.

Unfortunately, it worked a little too well.

A large group of moms were quickly enamored with the hunky single father. Derek was in his late twenties and he had nicely shaped muscles. Plus, thanks to his werewolf metabolism, he had impressive abs that always popped against his t-shirts.

The lustful stares from the moms only led to Derek also receiving envious glares from the dads, a majority of them having big dad bods that were complete with jiggly bellies. Derek wasn’t oblivious to the jealous looks he’d gotten from the dads, which was why he was confused when they’d invited him to a barbecue.

Again, wanting to be neighborly and hopefully quell any hard feelings, Derek accepted.

When he arrived to one of the dad’s house, he tried his best to be as friendly as possible. The host, a beefy man named Jim, warmly welcomed Derek and led him to the backyard where a bunch of the other dads were.

At first, Derek felt a little awkward at the barbecue, trying to engage some of the other dads in conversation. It always seemed to go the same way though:

“Hey, how’s it going?” Derek would ask one of them.

It seemed to always be met with an envious, silent glare from whichever dad Derek had tried to talk to. The dad would only shift his eyes from his gut towards Derek’s rigid abs, a frown set deep on his face.

Derek was about to leave when Jim walked up and clapped a large hand onto Derek’s shoulder. “Here, Man,” he cheerfully said as he handed Derek a beer, “this will help ya loosen up a bit.”

“Um, thanks?” Derek muttered as he took the offered drink, noting that the silver can lacked a distinguishable brand. Still, not wanting to be rude and alienate all the dads at Eli’s school, Derek brought the can up to his lips and took a hesitant sip.

The werewolf caught the almost victorious grins from the other dads as he drank the beer. None of them were being stealth, causing the hairs on the back of his neck to stand up.

“Wha— UURRPP!” Derek’s words were cut off when he belched loudly. He covered his mouth and blushed.

Jim only snickered and clapped Derek on the back. “Y’know Derek?” he asked, a playful quality to his deep voice. “You’re a nice guy and all, but a couple of us dads are growin’ a little irritated with the way you just stroll into town and show off your chiseled abs for our wives to gawk at.”

Derek cocked his eyebrow at the other guy. “What, UUURRPP, do you mean?” he asked, bristling at his seemingly uncontrollable burping.

Jim snorted and grabbed at his rotund belly with both hands, giving it a shake and causing the fat to jiggle. “My wife actually said, ‘Why can’t you work out and get a bod like Mr. Hale?’” he mocked, his voice going higher when he imitated his wife. “Yeah, fuck that. I hate cardio, so we all figured that it’d be easier if we made you look like one of us.”

“UUURRPP!” Derek burped, wincing when he felt a tightness growing in his stomach. The werewolf looked down and his eyes nearly bulged out of his skull at what he saw.

Derek witnessed his impressive abs pushing outwards against his tight t-shirt. Given his tight clothing, he could easily see every crevice of his hard-earned abdominals. Therefore, it was all the more jarring for him to watch as his six pack steadily went to a four pack, then two, and then flat. However that flatness didn’t last before his belly lurched forward, straining against his constricting shirt.

“What, UURRPP, are you doing to me?” Derek panicked as his frantic hands tried to press against his growing stomach, as if he could actually prevent it from getting bigger. Unfortunately, his gut only continued to pack on more fat as was evident by the way it began to jiggle as Derek readjusted his stance to account for his new weight. He could even feel his pants start to tighten as love handles sprouted and started to sag over his jeans. Toned pecs even puffed up, sagging slightly yet still showing off the impressive muscle beneath the layers of fat. His nipples stretched out to the size of sand dollars and perked up, becoming large and nubby at they strained against his shirt.

RIIIPPPP!

Derek’s straining t-shirt finally lost its battle against his growing bulk, and as he grew, Derek couldn’t stop the loud burping that echoed from his agape mouth. 

Finally, Derek felt the tightness in his stomach disappear and he breathed a sigh of relief as he stopped growing. That relief, however, was short lived when he looked in the sliding glass door and saw his opaque reflection. Derek’s previously toned musculature was completely gone, replaced with a total dad bod that was complete with a huge, hairy belly. Instead of looking like he’d visited the gym religiously, Derek gave off the appearance of a couch potato who drank lots of beer and gorged on tons of junk food. Derek looked downward and frowned when his newly inflated gut blocked the view of his lower half. He pressed both of his hands against his massive gut and gave it a tentative shake, paling when it jiggled almost as much as Jim’s huge gut.

“Here ya go, Bud,” one of the other dads said as he tossed a shirt at Derek.

Silent in shock, Derek caught the offered shirt, noting that it was a size XXL. His arms seemingly moved on their accord, and Derek tugged the white t-shirt on. Due to his increased size, his pecs strained the shirt to bursting, and his nubby nipples pressed against the tight fabric noticeably. Worse for the werewolf was that his new gut was so large that the bottom of the shirt kept riding up it and exposing his fuzzy bellybutton, making it look like Derek was wearing a crop top.

Derek’s face was beet red when he took a hesitant step forward and felt his unwanted bulk shake with every step he took, his gut protruding far out in front of him and jiggling constantly. He looked around the group of dads and realized that he was nearly on par with all of them, his new massive belly matching every other dads’ in the group.

Jim offered Derek another beer, this one with a recognizable brand which indicated that it was a normal one. “Hey Derek,” he said, giving Derek a playful slap on his new belly, sending ripples through the werewolf’s new gut, “a couple of us dads are in a bowling league and we’re lookin’ for a new player. You in?”

Derek’s words dried up in his mouth, and despite his anger, he found himself nodding, some unknown force making him calm down the slightest bit, especially as he took a sip of the offered beer.

“Great!” Jim happily said. “I don’t know if we have a uniform shirt big enough for that massive dad bod ya got there, but you don’t mind, right?”

Derek felt the corners of his mouth pull up and he ran his free hand over his exposed, hairy belly. “I’m used to it,” he heard himself say. “It’s hard to find a shirt that fits over this big belly— UURRRPP!”

Day 08: Cock TF

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08

When Derek woke up, all that he could see was darkness, as if there was a sheet yanked over his head. Instinctively, he moved to yank whatever was covering his head, but he realized that he couldn’t move.

Immediately, panic started to seep throughout Derek as he realized that he was practically paralyzed, unable to move a limb. He thought that it was sleep paralysis at first, but eventually he felt himself shift around and being moved without any say so of his own. Derek panicked as it felt as if he was being carried, unable to feel his legs carry him towards something, that fabric still covering his eyes like a blindfold.

“Ready for a surprise, Derek?” a familiar voice asked the alpha.

“What? Theo?” Derek asked, growing angry over what was happening. “What the fuck is going on?!”

“You were always such an annoyingly cocky alpha, so check this out!” Theo chuckled.

The “blindfold” was ripped away from Derek’s face, and the first thing he noticed was Theo’s smirking face. However, it was wrong in the fact that it was much higher up than it should’ve been, as if Theo were several feet taller than the alpha werewolf. That thought was quickly ignored when Derek looked directly into the mirror that he was standing in front of, screaming loudly when he noticed what was wrong.

“What the fuck?!” Derek roared as he stared in horror at his altered form.

All Derek could see was Theo’s long cock that dangled between his thick thighs. However, instead of a regular-looking cockhead, Derek saw his own head attached to Theo’s shaft. It looked as if someone had photoshopped Derek’s head on top of Theo’s cock, editing out his arms and legs.

Theo chuckled as he shifted his hips a little, causing his cock to wag back and forth, and thereby make Derek a little dizzy. “I was so tired of you and your big dick energy,” Theo explained, “so I decided to turn you into my cock. I thought about making you my butt, but I like this idea better.”

“You turned me into your cock?!” Derek repeated incredulously, unable to wrap his head around what was happening. “You better turn me back, right now! You hear me? Now!”

Theo mock frowned. “Don’t be like that, Sourwolf,” he teased. “I’m sure that you’ll love your new life as my cock.” He reached down and fondled himself a little, causing his cock to grow harder.

Derek’s angry face froze, and he wore a stunned look as he felt his new body stiffen. It was as if all of the muscles in his body was flexing in unison, becoming hard and rigid as his new cock body hardened. His head rose and stood out at an angle on Theo’s boner, bobbing the air.

Despite his panic, Derek’s hormones surged throughout his new body and all he could concentrate on was getting off. He was incredibly horny and all he wanted to do was jerk off his new body; however, without his arms, he was helpless and trapped at the chimera’s mercy.

Luckily/unluckily, Theo reached down and wrapped his fingers around Derek’s new shaft body, pumping his fist up and down.

Derek nearly went crossed eyed as his new body was jerked off, feeling as if tidal waves of pleasure were coursing all throughout his altered form. Memories of Derek jerking himself off paled in comparison to having his entire body felt up and played with. All of the nerves in his new body were intensified, forcing every touch on his smooth skin to electrify every pleasure center he owned. Derek couldn’t hold back his low moans as he was played with, almost loving it when Theo ran his fingers over his cock body.

Derek tensed up and felt one of the waves of pleasure inside of him break. A snap ruptured deep within him, and the alpha werewolf felt a pressure building deep within him when—

“Ooohh!” Derek moaned, his jaw opening wide as cum squirted out of it and onto the mirror in front of him. The salty substance coated his mouth and as he came; he blushed as he realized that he’d truly been turned into a cock, cumming on Theo’s behalf without a second thought.

Worse was that Derek couldn’t deny that he’d loved it. It was such an intense surge of pleasure that he’d felt, easily outweighing any solo session or any sex that he’d ever had. Being a cock was truly the gateway to the ultimate pleasure, Derek fearfully began to realize. 

That epiphany was soon forgotten when Derek stared back into the mirror, shocked to see his thick black hair beginning to recede. It slowly pulled its way back into his scalp until the alpha’s head was smooth. However, he saw that his head was oddly shaped, not looking as round as it should. Instead, there was an odd curvature to it, especially near the bottom that made it look more like a mushroom cap than a head.

Derek’s eyes winded even further when a slight indentation pressed inward at the top of his head, forming a piss slit. The stunned werewolf was helpless to do anything except watch as his mouth closed, his lips fusing shut until it vanished altogether.  His nose shriveled up and disappeared next. Finally, his eyes were next as they closed tightly and fused, yet he was still able to see.

When all was said and done, Derek stared back at a cock. The shaft and head blended in seamlessly, giving absolutely zero indication that it was Derek before. 

Derek couldn’t say anything or beg to be changed back. The only response he could give was twitch, causing Theo’s cock to throb and rocket back to life.

On cue, that glorious surge of pleasure erupted throughout Derek once again. He new head, the perfectly shaped cockhead, oozed precum.

“I’m gonna use you to fuck Stiles’s tight ass,” Theo snickered, wrapping his fingers around Derek’s cock body again.

Immediately, Derek succumbed to the intense pleasure rippling throughout his new body. He instantly gave in, knowing that his new body was built solely for pleasure and sex. He loved being a cock and he looked forward to all of the sexual experiences that he’d get to have.

Day 09: Merge

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09

“You’re the worst alpha I’ve ever had!” Peter yelled, throwing his hands up in the air dramatically.

Derek snarled in response, baring his massive werewolf fangs. “I wouldn’t have to be so hard on you if you weren’t so damn stupid!” he countered.

The two werewolves continued to argue and yell at each other, their bellowing voices echoing throughout the house and making peace nearly impossible. 

Meanwhile, Stiles rubbed at his temples in irritation as he tried to read some articles for his college classes, irked that he couldn’t get any studying done with the werewolves’ dick measuring contest going on in the background. Worse was that ever since Peter miraculously came back from the dead, he and Derek seemed to be at each other’s throats constantly.

“You’re the most selfish member of the pack!” Derek growled, puffing out his chest as he tried to threaten the older werewolf. “I should’ve kicked your ass out a long time ago!”

Peter, being the drama queen that he was, rolled his eyes exaggeratedly. “Oh please, Pup,” he spat. “You have no clue what the hell you’re doing. Shit, your little pack would fall apart if it wasn’t for my help.”

The two men kept yelling at each other, ruining any semblance of tranquility as they puffed out their chests in what could be described as a “Bro Off”. Both of them would bark and yell, yet neither one of them dared to throw the first punch.

Finally, Stiles slammed his book shut, over their childish behavior. “Will both of you shut the fuck up?!” he cried.

Derek and Peter both froze to stare at him in bewilderment.

“He started it,” Derek muttered, gesturing at Peter heatedly.

“I don’t care who started it!” Stiles exclaimed. “We’re all in the same pack, so if the two of you could figure out a way to be closer, that’d be perfect!”

As soon as the words left Stiles’s full lips, an electric quality appeared in the air, making the hairs on the werewolves’ arms stand at attention. Before anyone could ask what was going on, Derek and Peter felt themselves moving towards one another, their limbs acting on their own accord.

Against their will, Derek and Peter both raised their arms and seemingly embraced one another in a hug, the two of them wearing worried expressions on their handsome faces as they desperately tried to regain control of their bodies. Even Stiles was shocked, his jaw hanging low as he watched the two werewolves hug one another.

Then something else happened.

Derek was the taller one, and it seemed as if Peter’s smaller (yet still muscled) body melted into Derek’s larger one. As the werewolves merged together, their muscles appeared to combine, becoming larger and much more defined. Their arms combined, becoming larger with much bigger biceps than before. Pecs protruded out in front of their bodies, capped by large, nubby nipples that were twice the size of their respective ones. Even their clothes seemed to merge together, taking Peter’s blue button down and Derek’s white tank, morphing them into a blue and white muscle tank top that served to show off their large muscles.

Derek and Peter were stunned silent as their heads positioned themselves upon broadened shoulders, sitting side by side.

When the changes finally ceased, standing where the two werewolves previously argued with one another, was a two-headed muscle beast. Derek and Peter stared in shock and horror as they used the buff arm that they could control to feel around their shared body, blushing when they could feel the exact same sensations.

“Wh-what happened to us?!” Derek panicked, taking an awkward step forward as if he could pull himself away from his shared body. All that served to do was make his new body stumble, Peter in control of the other leg.

Even Stiles was stunned silent, unable to wrap his head around what was happening. Moments before, Derek and Peter had been arguing, and then they were sharing a body that was twice the size of their normal ones.

Peter felt around his shared body in disbelief, bristling when he noted the obscene size of his enlarged muscles. “H-how did this happen?!” he gasped, unable to wrap his head around the fact that he and his nephew shared an over-muscled body.

Stiles shook his head in disbelief. “All I meant for you two to be closer, not this!” he hurriedly cried. 

The two-headed werewolf struggled to stalk forward, each one of them using the leg that they controlled.

“You better figure out a way to fix this!” Derek growled. “How the fuck can I be expected to perform my alpha duties with this dumbass attached to me? And how can I be expected to be with my boyfriend when I’m sharing a body…” He trailed off when his thoughts were clouded over with Peter’s.

Derek turned his head to glare at Peter’s, who attempted to look away, but given their unwanted proximity, the attempt was moot.

“Really?”  Derek growled, anger bubbling up in his gut.

Peter blushed, but tried his hardest to look unbothered. “He’s kinda cute,” he muttered under his breath, referencing his secret crush on Stiles, which Derek could pick up on thanks to their shared body.

Both of the werewolves flinched when they felt a throbbing in their pants. They each used the arm they controlled to yank down their pants, revealing the twin cocks that they possessed. Both of the impressive members stood at perfect attention, directed straight towards the shocked human.

Derek and Peter sniffed at the air, surprised at the heat radiating off of Stiles.

“Really?” they both asked in unison, shocked at the fact that Stiles seemed to be turned on. 

Stiles shrugged cheekily. “Well, I love Derek, but I also think that Peter is hot, in a weird sorta way,” he admitted, blushing.

Derek and Peter sighed, their shared shoulders rising and falling with the action.

Derek used his arm to scratch at the back of his head. “Well,” he mumbled, “I guess we could try to make this work…”

Peter looked downward at the two cocks that were attached to his and Derek’s shared body. “I hope that Stiles can take two at a time,” he said.

Stiles eagerly nodded. “I can look up some stretches!” he rushed, already looking forward to getting fucked by his new two-headed boyfriend.

Day 10: Bear

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10

Derek and Peter Hale groaned as they waddled off the beach towards their car.

Just moments before, the two werewolves had been toned men researching some strange disappearances in the area. Locals would say that men would go and visit the infamous Bear Beach, only to be never heard from again.

Peter winced at the odd feeling of his beefy arms resting atop his lats. “I’m just saying, Almighty Alpha,” he sneered in Derek’s direction, “that maybe there’s a reason the place was called Bear Beach.”

Derek just grunted, not used to the way his rotund, hairy belly jiggled with every step he took. “I thought it was just a name…” he grumbled under his breath, a growl barely detectable.

Peter scoffed and gestured back towards the shore where loads of beefy hairy men lumbered around clumsily, as if they were learning how to walk. “That didn’t tip you off?” he huffed. He wanted to argue more, but instead tensed up as a slight breeze wafted over the two of them, his chest hair being billowed by it.

Derek gritted his teeth as he tried his best to ignore the tingling the breeze caused on his nubby nipples, making his cock start to stir in his tattered shorts.

The very second Derek and Peter had stepped foot on the elusive Bear Beach, they’d immediately felt themselves beginning to change. The first thing the werewolves noticed was the way their jaws had sprouted thick beards, soon followed by hair covering the rest of their bodies— especially their chests. Before either of them could even think to get away from the beach, both of their bodies exploded with flesh. Muscles inflated, but were quickly engulfed by a thick layer of fat that seemed to be centered on their new guts. Their shirts had ripped to shreds, showcasing their massive, pillowy pecs that were capped with large and sensitive nipples. However, their big bellies seemed to be the focus of their growth, making it look as if both of the werewolves had swallowed yoga balls. Derek and Peter’s guts protruded out in front of them, obscuring the view of their own lengthened cocks that dangled crazily as their widened thighs rolled over each other with every step. Even their backs had widened as their large arms puffed up, giving each man a roundish, yet muscular, appearance.

The two werewolves had been turned into total bears simply by stepping foot on Bear Beach.

As soon as the shock of their transformation wore off, Derek and Peter were alerted to the fact that every other man on the beach seemed to share their shocked expressions— all of them looking down at their own massive, hairy form in confusion.

Now the two bear werewolves waddled back to their car, trying to get the hang of moving around with large thighs constantly colliding with one another.

“We need to figure out a way to fix this,” Peter grunted as he poked at his big belly. “I don’t think any of my designer shirts will fit.”

“You poor thing,” Derek snorted, freezing as soon as he heard a loud rip and his shorts finally gave way to his thickened lower half.

The tattered fabric fell to the ground, revealing the alpha’s thickened cock that was at least nine inches and about as thick as a soda can. Not to be outdone, his large hairy ass had ballooned to an exaggerated size, looking like two fuzzy basketballs were strapped to his back.

“Damn it!” Derek roared as he stomped his foot in frustration, flinching as the movement sent a ripple through his massive butt, gut, and pecs. He blushed like crazy. “L-let’s just get out of here.”

The bears lumbered towards Derek’s Camaro, but they had a hard time squeezing their unwanted bulk inside.

Peter, being the smaller of the two, had an easier time, but he still struggled. He wasn’t used to the feeling of having a large gut resting on his lap when he sat down, and he was annoyed at the way his seatbelt completely disappeared between the crevice of his hairy pecs.

Derek had a much harder time. It took all of his cunning to wedge himself into the driver’s seat. He had to shove the seat all the way back, and even at its furthest, his furry belly still pressed against the steering wheel a little bit. Whenever he gulped in a large breath of air, his gut would push out slightly and tap the horn, making him cringe. Worse was that whenever he turned the wheel, his beefy arms would brush against his nubby nipples, making him stifle a moan. It was obviously that his bulk turned him on despite himself, as his humongous cock stiffened and began to bob out at an angle due to his large belly.

“Hopefully Stiles can figure out a way to fix us,” Peter moaned, squirming in his seat as the car’s A/C blew over his mountainous pecs, feeling like someone was running their fingers through his chest hair.

“Yeah,” Derek grunted as he accidentally jostled a nipple again, “…or maybe we can squish him between our bellies first?”

Day 11: Pup

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11

Derek wasn’t in control. He couldn’t help it.

The alpha werewolf had no clue what was happening, but the second he heard his husband, Stiles, walk in the front door after getting off from work, he felt a surge of excitement and utter jubilation. Of course Derek loved this husband and was always happy to see him, but this was to a new extreme— almost inhuman.

“I’m home!” Stiles called out.

At the sound of his husband’s voice, Derek’s heart raced and he dropped the TV remote and felt his body crash down to the floor on all fours. Before Derek could wonder what he was doing, he felt his limbs scamper out of the living room and towards the entryway. Inwardly, he panicked, unable to stop crawling on all fours or even stand up. Whenever he’d try to, he’d fall back down onto hands and knees, forced down like a dog.

The second his panicked eyes landed on Stiles, though, Derek’s trepidation vanished.

“Woof! Woof!” Derek cheerfully barked and he sprinted towards his husband. He rushed forward and managed to stand up on his feet— well, more like he leaned his top half against the smaller man, again, akin to how a dog jumps on their master. Unable to contain his joy at seeing the other man, Derek leaned forward and licked his husband’s face all over like a puppy.

“Derek, what are you…” Stiles trailed off, looking confused as the werewolf licked him. His eyebrows scrunched together, and his brain tried to tell him that something was wrong, that Derek was acting different. But as the excited mandog continued to give him kisses, he brushed the feeling away and couldn’t help but laugh.

At this sound, Derek couldn’t help but bellow out another, “Woof!” He blushed when he felt his bubblebutt jiggle a little as he wiggled his hips to and fro, almost as if he’d had a tail. Worse was that no matter how hard he tried to, he couldn’t seem to stop himself.

“Okay, Derek, down,” Stiles laughed as he gently pushed against the eager man.

Derek put all fours back down again at the command, his blush deepening. He had no idea what was happening, but a part of him hoped that Stiles could figure out a way to help him. He opened his mouth to ask for help.

“Hrrmm, woof!” Derek barked, his eyes widening. “Woof! Woof!” His deep voice sounded the same, but no matter how hard he tried, Derek couldn’t put together a sentence. His words were reduced to barks and yips, making him let out a loud whimper.

Stiles hung up his coat and turned back to the crawling Derek. “Aww,” he frowned exaggeratedly, “what is it, Der? You want some pets?”

Inwardly, Derek bristled at the way his husband was talking to him, as if he were his pet. However, his body perked up and he wiggled his hips even more. “Woof!” he excitedly barked, so into it that his hands lifted off the ground with the movement.

Letting out a chuckle, Stiles leaned down and scratched behind Derek’s ear.

The feeling was incredible and Derek leaned further into it, barely noticing the way his leg shook. The sensation of Stiles’s hands on him was intoxicating, and his canine mind craved more.

Derek flopped over onto the floor and rolled over onto his back, his arms hanging out awkwardly in front of himself as he presented his hairy chest to Stiles. Derek looked up at the other man expectantly, despite inwardly screaming at himself to stop.

“Aww, good boy!” Stiles cooed as he gave Derek a belly rub.

Instantly, Derek felt his cock rocket to life, slipping out of his boxers and bobbing out in the air. He couldn’t believe that he was acting like a dog, getting a belly rub from his husband. But he couldn’t deny that he loved it. Something about the way Stiles’s hands ran over his body was purely orgasmic, and the werewolf craved more. Every hairy crevice of his muscled chest was felt up by Stiles, and when his fingers ran over his hard nipples, Derek was pushed over the edge.

“Arroooo!” he howled as he came, his cum shooting up into the air and landing all over his pecs. He panted as he tried to catch his breath, feeling as if he’d just blown the largest load of his life.

Stiles stood up. “Let me change and then we’ll go for walkies,” he said as he walked up the stairs.

Alone, Derek’s mind finally cleared enough for him to start to freak out over what was happening to him. Gritting his teeth, he tried with all of his strength to stand up or speak, but it was futile. Finally giving up on that, he crawled around the downstairs, shocked to see that the house had changed. There was now a dog bowl in the kitchen with DEREK printed on it in large, blocky letters. Unable to help himself, Derek crawled over to the water bowl next to it and lapped up some water noisily, splashing liquid all over the hardwood floor in the process. He leaned up, his face cherry red at his actions, but his thirst satisfied at least. 

Scampering into the living room, Derek winced at the large dog bed in the corner along with the rubber toy in the shape of a bone.

The mere second Derek’s eyes landed on the toy, his heart began to race and he couldn’t help but rush over and happily take the toy in his mouth. Whenever he tightened his jaw on it, it let out a loud squeak, further exciting the werewolf even more. He happily thrashed his head around, loving the squeaking from his chew toy.

“Ready?” Stiles asked, interrupting his play time as he walked down the stairs in more comfortable clothes.

Derek cocked his head to the side and dropped the toy from his mouth, humiliated beyond belief. He was used to be a boasting and powerful alpha, not some damn puppy! Still, as Stiles grabbed the leash off the rack, Derek scampered forward eagerly.

“Sit,” Stiles said as he held out the black, studded collar. There was a small sliver tag on it that read out: Derek, along with Stiles’s phone number.

Derek immediately sat like a dog and straightened his torso as best as he could. He puffed out his chest muscles with pride, loving the way Stiles looked over him. He was such a good guard dog— no, wait, he didn’t mean that.

Stiles put the collar on Derek and attached the leash, barely having time to open up the door before Derek excitedly bolted out. 

The smell of the fresh air and the sounds of the birds chirping was so much, and Derek couldn’t help but whip his head around to take in all the senses. He loved the bright colors of the cars that zoomed by, and he couldn’t help but preen at how Stiles walked in line with him. Derek’s tongue happily lolled out of his mouth as he walked.

The two of them came to an intersection, and without thinking, Derek sat down and looked upwards at Stiles.

Stiles looked left and right before nodding down at Derek, the werewolf standing back up on all fours and continuing their walk.

“Good boy, Derek!” Stiles cooed. “That’s a such a good boy for waiting to cross the street!”

“Woof! Woof!” Derek happily barked, loving how Stiles praised him. He was such a good boy, especially for Stiles.

“Hey there, Stiles!” a voice enthusiastically echoed out.

Stiles looked away from Derek and then smiled lazily at Theo, who walked towards the two men. “Oh, hi Theo,” Stiles said, in a less cheery voice. This one almost sounded distrustful. 

At the sound of Stiles’s change of tone and the approaching of the other man, Derek couldn’t swallow down the fierce protectiveness that bubbled up in his chest. He stomped forward and puffed out his chest as best as he could, steeling his arms to make his muscles look even bigger.

“Grrr!” Derek growled at the other man, making him stop in his place.

Stiles tightened his grip on the leash and kept Derek back, offering Theo a meek smile. “Sorry, Theo,” he huffed, “Derek’s not great with other people yet. I’m still getting him trained.”

Derek stopped growling, but kept his large werewolf fangs bared threateningly at the other man.

Theo held his hands up and shook his head with a chuckle. “Well, I know you’ll get him trained well soon,” he sighed. “You always said that you wanted a dog…” With that he turned around and walked off, but Derek could’ve sworn that he’d heard him mutter “…I must’ve messed up the spell…”

Stiles and Derek finished their walk, the whole time Derek loving the quality time with his husband. Derek had loved smelling all of the flowers in their neighbors’ yards, he'd enjoyed the way Mrs. Hall ad given him a pat on the head (it’d been nothing like Stiles’s head pats though), and he’d chased a squirrel much to Stiles’s annoyance.

When they returned home, Stiles fed Derek some food, which Derek happily gobbled up. He followed Stiles around the house as he did little chores here and there until it was nighttime. 

“Time for bed, Der,” Stiles yawned, stretching his arms over his head and he sauntered towards the bedroom. He hopped in the bed and lied down.

Derek followed him into the room and spun around a few times before lying down on the dog bed that was at the foot of his bed. There was a rawhide there from earlier, and Derek chomped down, gnawing it with his large teeth. He was so happy. He had the best master in the whole world, he got a belly rub earlier, and he got to have walkies.

It couldn’t get any better than this—

“It’s kinda cold,” Stiles shivered. “You want up, Der?” He patted the mattress.

“Woof! Woof!” Derek excitedly barked as he jumped up onto the bed and scurried over to his Stiles, licking his face lovingly. 

“You’re such a good boy,” Stiles laughed as he scratched behind Derek’s ear.

“Woof!” Derek happily barked, his wide and toothy smile dominating his face.

Day 12: Bunny Boi

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12

“You’ve got to be shittin’ me,” Derek growled as he looked over the ridiculous outfit that was in the bag.

Derek had lost a bet with a fellow alpha, and as punishment, he would have to wear an incredibly embarrassing outfit for the day.

Derek grimaced at the lacy corset that had matching garters, and a cringey set of bunny ears to top everything off.

There was a loud knock on the other side of the bathroom door. “You better move it, Hale,” laughed Nate, the other alpha who was apparently a total freak.

“Son of a bitch,” Derek spat, taking off his leather jacket and jeans so that he could put on the stupid bunny outfit. The alpha werewolf slid on the panties first, rolling his eyes at how small they were. His cock was so big that it filled the tiny pouch to bursting, yanking the tops of the underwear downward to show off his trimmed bush and the base of his dick. Clenching his jaw, Derek pulled on the corset, which was at least two sizes too small for his muscular body. It was nearly impossible to close it shut around his thick waist, and his pecs completely spilled out over the top, his nipples poking out noticeably. It was so tight, in fact, that Derek felt as if his midsection was being squeezed so tightly that it shoved his pecs outwards even more. He put on the lace garters, feeling ridiculous the whole time.

When he was finally all dressed up in his humiliating outfit, Derek begrudgingly opened up the door, revealing a smirking Nate.

“Lookin’ good, Hale,” Nate whistled, making a show of eying the alpha up and down. “Oh, but wait! You forgot something.” He reached over and snatched the bunny ears off the sink before plopping them on top of Derek’s head.

“Gee, thanks,” Derek muttered under this breath, the headband attached to the bunny ears giving him a little headache.

“Well, c’mon, I’ll show you what chores you can do, and then we can call everything even,” Nate boasted as he stomped down the hallway, his broad back swaying with every powerful step he took.

Derek blushed as he took a step in his stupid outfit. His muscles squirmed against the tight fabric, making him have to almost arch his back in order to get semi-comfortable. The action only led to his large pecs being thrusted forward, his nipples resting atop the lacy corset, constantly rubbing against the soft fabric. The way the straps from the corset attached to the garters around his thighs made his steps resemble more of a mincing movement, soft and delicate.

Nate led Derek to a messy bedroom that completely matched Nate’s frat boy attitude. Clothes were strewn all over the floor, the bed was a total pigsty, and there were pizza boxes and empty beer bottles scattered all over the cluttered floor.

“Go ahead and start with my room,” Nate laughed.

“What a fuckin’ mess— Oh!” Derek squeaked when Nate gave his butt a playful smack. His cheeks bounced from the motion, and Derek’s face grew red.

Worse was that his cock twitched for some reason, almost thrusting out of the confines of his small panties.

“Fuck off,” Derek barked, stomping angrily into the messy bedroom, trying to shield his hardening member from the other man.

He snatched a trash bag out of the pile of cleaning supplies, starting to toss a bunch of the garbage into it. As he moved around, Derek’s nipples get rubbing up against the lace of the corset. It must’ve been due to the softness of the outfit, but it seemed as if Derek’s nipples were hardwired directly to his throbbing cock.

The alpha bit down on his bottom lip, trying desperately to resist the electrifying feelings that rippled through him as the corset stimulated his sensitive nips.

“This is so fuckin’ stupid,” Derek growled, tugging the collar of the corset downward to give his nipples some relief. However, once he let go and it snapped back into place, he had to bite back a moan as it started rubbing up against them some more.

As he continued to mince around the bedroom cleaning, Derek’s hard cock kept throbbing with want inside the tight confines of his panties. The cotton was stretched to the limit, and every so often Derek would give in and rub his aching bulge with one hand while using his other to thumb one of his nips.

Derek started to toss the other alpha’s clothes into the hamper. He flitted about the room, hard nipples and harder cock, bending down and grabbing fistfuls of Nate’s clothes. His musky scent clung to every fabric, that manly musk permeating Derek’s senses.

Derek grabbed a jockstrap off the ground, seeing that it was a size XL.

“Ooh, big boy,” he cooed, before flinching and slapping a hand over his mouth. “Why’d I just say that?”

His perky nipples still burned and his cock throbbed like crazy, at full mast. Still, it hadn’t burst through the small panties, and Derek couldn’t help but reach down again to feel himself up. His hand ran over his rock hard cock, freezing as his fingers grazed his bulge.

“I-is it smaller?” Derek gasped, looking over his pecs to the bulge in front of his humiliating panties. Sure enough, the lump in front of his meaty thighs wasn’t as prominent as it had been moments before, looking tight and compact.

Derek quickly tugged the panties downward, paling at the sight of the four inch cocklet poking out of his trimmed bush. With a shaky hand, Derek reached down at his shrunken member, wrapping his fingers around it.

“Oooh,” he moaned, unable to keep his lips shut at the surge of pleasure that rippled through him. Despite the panic that was coursing through his veins, the werewolf couldn’t help but fondle his tiny cock that made him feel even more ridiculous with his massive muscles in such a girly costume. He knew that he should be panicking even more, to tear the apparently cursed outfit off, but his frazzled mind was so clouded over with lust that it was difficult to think about anything else.

“Did I say that you could play with yourself?” Nate’s deep voice bellowed.

Derek jerked back and blushed as the other man stared him down. 

Nate smirked as he crossed his beefy arms over his large chest. Derek hadn’t noticed before, but Nate had large muscles that were so big and manly. His pecs stretched his t-shirt to bursting, and his biceps curled out the tight sleeves. His bulge in the front of his jeans was much, much larger than Derek’s diminished one. And manly musk radiated off of Nate in waves, making Derek’s mouth water.

“No, Sir,” Derek answered promptly, his voice light and almost airy. Instantly, he dropped his muscled arms to his side, his tiny cock throbbing as it stood at attention in front of him. The more Derek stared at the other alpha, the more his small cock throbbed and his perky nipples burned with want. His unknown desire was starting to creep up to higher levels, and he couldn’t help but shift his feet under Nate’s gaze, rubbing his thighs together in anticipation.

Nate gave a tsking motion with his finger. “Well, finish up then, Bunny,” he ordered. “Then I’ll let you play with your tiny nub.” He walked away.

“Yes, Sir!” Derek excitedly said, picking up his pace as he minced around the room, his pert little cock bouncing in front of him as he moved. 

He didn’t know why his heart raced at the thought of being ordered around by such an alpha like Nate. The frat boy was stacked with such manly muscles, and some of his chest hair curled over the collar of his t-shirt— a stark contrast to Derek’s smooth muscletits that bounced with every step he took. His little nub leaked precum the whole time he finished cleaning. Once he was done, Derek eagerly rushed over to Nate to deliver the good news.

“All done, Sir!” Derek reported, smiling widely at the alpha.

Nate looked away from the TV. He’d taken off his shirt, resting his arms behind his head, letting his musky, hairy pits air out in the open. “Good job, Bunny,” he grinned at Derek. “Why don’t you take your uniform off? Don’t wanna mess it up while you service your alpha.”

“Yes, Sir!” Derek happily gushed, practically ripping his panties and corset off. He paused for a moment as he looked over himself. His tiny, three inch cock was as hard as ever, yet it seemed so small and utterly tiny— especially in comparison to the large eight inches that Alpha Nate had. And even though his corset was off, Derek’s pecs were still pushed upwards and out, looking slightly larger and more bulbous than they should’ve. His nipples were hard and nubby, sticking off his muscletits like little erasures. Something was wrong, this wasn’t how Derek should’ve looked… was it? He didn’t know why a tiny voice in the back of his head shouted that he was supposed to be a manly alpha like Nate, not some sub bunny boy.

Nate unzipped his pants and fished his own cock out, letting his large member bob in the air. “You gonna stand there or are you gonna take care of this?” he bellowed.

Derek quickly squashed the voice in the back of his head and hurried forward, his muscletits bouncing with every minced step he took. Dropping to his knees, Derek leaned forward and hungrily took the entirety of Nate’s cock into his mouth, sucking it like a pro. 

“That’s a good bunny,” Nate teased, toying with the bunny ears that were atop Derek’s bobbing head.

“Mmmm!” Derek loudly moaned, his little nub spurting tiny droplets of cum as he sucked off his alpha, loving his role as his muscled up bunny boy.

Day 13: Clown

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13

Derek practically whimpered like a wolf pup as he watched his husband, Stiles, slowly slump to the couch. The usually vibrant and cheerful human had been going through some hardships at work, and it’d really affected his mood; thus, the normally smiley and singsongy Stiles was all gray and sulky. The alpha werewolf frowned as he saw Stiles’s thin shoulders rise and fall with a sigh.

On a normal day, Derek was the grumpy one, mad at the world and scowling at every living creature that dared to cross his path; and Stiles would be his anchor, calming him down with a simple kiss on the cheek or by placing a warm hand on his broad shoulder. Now that the roles were evidently reversed, Derek was struggling to find out the right things to do/say, empathy never really being one of his strong suits.

“Babe?” Derek asked as he walked over to the couch and placed a hand on his husband’s shoulder as he would’ve done had the roles been swapped. “Um… have you tried not thinking about it?”

Stiles’s frown deepened and he rubbed at his temples, making Derek feel guilty.

Derek flinched and quickly tried to make things better. “Got a headache?” he asked, already dashing to the bathroom. “I’ll grab you some Ibuprofen!”

As Derek leaned over the sink, images of his sad husband kept replaying in his mind, making him grimace. He felt guilty for not being able to cheer up Stiles like he would do for him whenever he was moody. He couldn’t help but feel a little helpless and, what was worse, was that whenever he felt like this, it was usually Stiles who convinced him of otherwise with a little corny joke.

Derek loved his husband with all of his heart, and it pained him to see Stiles sad. He missed his smile, he missed his laugh.

“Damn it,” Derek cursed under his breath, “I wish I could cheer him up.”

The second the words left his mouth, Derek felt a shudder ripple through him. The sensation morphed into an odd tingling that consumed his whole body before fading, but not before being reduced to a tickle that actually made Derek laugh.

“Hyuck! Hyuck!” Derek guffawed, his normal throaty chuckle sounding more like a cartoonish wail that was comically deep. The werewolf jerked back and cleared his throat, wondering why he’d just laughed like that.

He shook it away and opened up the mirror cabinet to grab some Ibuprofen for Stiles, gasping when he saw his reflection after closing it.

His normally jet-black hair was green! Derek dropped the small pills in shock as he ran a shaky hand through his green hair, his eyes wide at the vibrant color that would without a doubt, draw a lot of attention his way. 

“What’s, *giggle, wrong with my hair— Hyuck! Hyuck!” Derek laughed again. This time, he finally realized that he’d been smiling the entire time. Although he was confused and slightly panicked over what was happening to him, his face looked alight with zeal. His pearly whites were on full display, which brought about something new to him. Derek had always had larger front teeth, Stiles sometimes referring to them as Bunny Teeth, but his eyes widened when he saw them grow in size until they protruded over his bottom lip, effectively giving him over-exaggerated buck teeth.

Derek barely had time to react to his large teeth before he witnessed his nose shudder. Its skin reddened drastically until it looked cherry red, even taking on a shimmery sheen. It then steadily inflated, rounding out until Derek had a red clown nose affixed to his face.

“I look ridiculous!” Derek giggled, still grinning widely despite his inner panic.

The altered werewolf’s first thought was to rush to Stiles, knowing that his husband would figure out what was happening to him. Derek quickly hurried out of the bathroom, stumbling over his feet as he moved. Derek’s eyes widened even further when he witnessed his feet elongating past their usual size thirteen, growing comically huge with large stumpy toes capping them. 

With each step he took, Derek’s new feet slapped loudly against the hardwood floors and he struggled to maintain his balance. His gait resembled someone more clumsy, struggling to walk a straight line. He kept bouncing against the walls, knocking over pictures and causing a ruckus as he moved.

With a loud giggle, Derek waddled into the living room where Stiles moped. His husband took one look at him and scrunched up his eyebrows in confusion. 

“Der?” he asked. “What are you doing?”

Instead of asking for help, Derek heard himself laugh, “Hyuck! Hyuck! I heard that there’s someone who’s a little down!” He cringed at how he was acting, this cheery clown attitude a direct contrast with his usual self.

Stiles just stared blankly ahead. “Huh?”

“Want a balloon?” Derek happily asked. “I got a real big one for you!”

With large, flailing motions, Derek searched all around his clothes. His busy show wouldn’t allow him to display his shock over the bright neon colors that his black clothes had been magically dyed to. Derek felt as if he were a passenger in his own body, hearing himself speak and feeling himself move, but he didn’t have any control. He was helpless as he behaved like some sugary sweet clown, unable to stop smiling and giggling the entire time.

When Derek couldn’t find a balloon, he frowned before perking up with an a-ha motion. Pursing his lips and whistling through his large buck teeth, he unzipped his now bright yellow pants and let them fall to the ground. 

He exaggeratedly gasped as he looked down at his soft cock, grabbing at his green hair. “Oh no!” he chirped. “You don’t want that small balloon!” 

He winced at calling himself small, but then flinched when he saw the corner of Stiles’s mouth slowly pull upward. Seeing Stiles doing so sent a fluttering feeling through Derek’s chest, and he started to feel a little excited, his panic steadily fading.

Derek felt himself stick his thumb in his mouth and take in a deep breath, puffing out his chest. He then puffed out his cheeks and acting like he was blowing air into himself, pausing every so often to take a deep breath.

Stiles let out a little chuckle.

Derek felt himself perk up, his cock instantly rocketing to attention. It swelled up and stood out in front of him. Derek dropped his thumb from his mouth and gestured towards his hard cock.

“Ta-da!” he cheered, puffing his chest back out and setting his hands onto his hips proudly as he pushed his hips forward so that his rock hard member was closer to his husband.

Finally, Stiles’s face broke out into a loud smile and he started to laugh.

At seeing his husband finally laughing and being able to see his beautiful smile again, Derek’s cock throbbed and began to leak precum. His own smile was back in full force.

“Oh, thank you, Der,” Stiles cooed as he sat up and gave his husband a big hug. “You always know how to cheer me up.”

“Hyuck! Hyuck!” Derek guffawed, his face blushing wildly as Stiles kissed his cheek lovingly. Seeing the love of his life smiling again, Derek figured that as long as it made his husband happy, he was fine with being a werewolf clown.

Day 14: Whoopie Cushion

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14

PFFTT!

The fart sound echoed out in the home office as soon as Derek sat down in his chair, his eyes widening and his face turning slightly red as the others in his Zoom meeting cocked their eyebrows at him.

The werewolf huffed as he reached under the cushion of his chair and pulled out a deflated pink whoopie cushion, the pink joke toy making him sneer at his husband and son’s childishness. 

“Yeah, sorry about that,” he said to his coworkers. “My husband thinks he’s funny.”

The rest of the Zoom meeting went without any sort of hiccup, however Derek kept the whole whoopie cushion fiasco in the back of his head, biting back a growl over how foolish it had made him look. The alpha werewolf certainly wasn’t known for his stellar sense of humor, and while he cherished his husband Stiles’s silliness and the way it’d rubbed off on their son, Eli, there were times when Derek grew tired of being the butt of their jokes and pranks.

That led the patriarch of the Hale Household to rally up his family into his van and speed down to the local prank shop, whoopie cushion in hand.

“Der, you don’t need to return the cushion to make a point,” Stiles moped in the passenger seat. “Besides, it’s used. They won’t take it back.”

Derek silently brooded, clenching his jaw in irritation. He hated to look like a stick in the mud, but he felt that someone had to be the serious one in the household, and unfortunately, that responsibility landed on his shoulders.

He pulled up into the store’s empty parking lot, and stormed out of the van. Derek stomped into the store and slammed the deflated whoopie cushion onto the counter in front of the startled old man.

“What kind of adult sells childish toys like these… to other adults?” Derek roared, flinching at the last part of his statement.

The old shop owner simply readjusted his glasses as he stared upwards at the angry werewolf, his lips pursed into a thin line. “It’s just meant for fun,” he tried to explain. “Why don’t you try to loosen up and just have a laugh every now and then?”

Derek bit back a growl at the older man’s worse, feeling oddly defensive. “I am fun,” he snarled, “I just don’t have time for childish shit like whoopie cushions. These aren’t funny, they’re annoying!”

The older man didn’t look phased by Derek’s outburst and actually yawned. “You’re not fun,” he coldly muttered, before a chipper quality crawled into his scratchy voice. “But, I can help you with that.”

Before Derek could ask what the old guy was talking about, he felt an odd electric shock quality run all over his body. It caused the werewolf to tense up, his skin feeling tight for a second before all of his muscles seemingly relaxed.

“What the hell was that?” he asked the older man. 

The man seemed to fight back a smile as he stared at Derek, making the werewolf all the more angry.

Before Derek could take a swing at him or yell some more, he looked downwards in the direction of the man’s gaze, his eyes widening at the pinkish hue to his skin. Derek was normally pale, but now his skin was starting to brighten and look like it was a bubblegum pink, more akin to a pencil erasure than his usual skin tone. Weirder, and even more apt to the erasure comparison, Derek could smell the faint stench of rubber beginning to emanate from him in waves, making him cock his eyebrow.

Carefully, Derek reached over and pinched his arm, pulling back with his hand. The werewolf nearly yelped as his skin now possessed an elastic quality which caused it to stretch outwards beyond the realms of possible. Derek’s heart raced in his chest as he realized that he’d been turned into rubber!

A hiss like a tire being inflated echoed out in the small prank shop, and Derek felt his clothes growing tighter by the second. Looking downward at himself, Derek was shocked to witness all of the muscles in his body steadily inflating. He’d already been blessed with large, manly muscles, yet now they started to bulge out and round. They looked cartoonishly big, with round qualities to the point where he seemed more inflated than muscular, like most of his muscles were full of air. Even his cheeks puffed outwards; and speaking of cheeks, a lot of the growth was centered at Derek’s ass, which bubbled out into large beachball sized globes.

“Wh-what did you do to me?!” Derek roared as he explored his pink, inflated body with his shaking hands.

The older man just continued to fight back laughs. “I figured that this would help you learn how to laugh more,” he snickered.

“What does that even mean?!” Derek cried, taking a tentative step forward, flinching at the sound that echoed out.

Pfffttt!

Derek froze, his eyes widening before they narrowed towards the shop owner. “You turned me into a fuckin’ whoopie cushion!” he accused, holding his arms out to show off his inflated form. However, little poots were heard at the brisk movement, making the werewolf blush.

The older man waved his wrinkled hand dismissively. “It’s only for a few days,” he muttered before gesturing at the whoopie cushion on the counter. “Oh, and no returns on used products.”

With a growl, Derek snatched the whoopie cushion off the counter and stomped out of the store, bristling with every little fart noise that sounded out with each step he took. A few people out on the street would giggle in his direction, especially at the noises that he was helpless to make, making his pink face turn a dark red with embarrassment.

Worse was that once Derek reached the van, Eli and Stiles were stunned silent as they gawked at his whoopie cushion body… then they both burst out laughing.

Derek just bared his werewolf fangs at them in irritation as he opened up the driver’s side door and jumped into the seat—

PPPFFTTTT!

The loud fart noise boomed inside the van as Derek sat down, his inflated bubblebutt squishing like the perfect whoopie cushion it now was.

Immediately Stiles burst out into hysterics, going so far as to wipe tears from his eyes at Derek’s helpless fart noises.

Derek just grumbled to himself and gripped the steering wheel tightly, the motion causing little fart sounds again as he drove home, fart sounds echoing out every time the vehicle hit a bump in the road.

“Damn it, *pfft, this is *pfft ridiculous,” Derek groaned.

31 Days of Derek Hale

Day 15: Caveman

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15

Derek wasn’t proud to admit it, but he had a little bit of a jealous side.

Nothing brought out the green-eyed monster more than watching some guy try to flirt with Stiles, or even hearing Stiles comment on how hot he thought a certain actor was. The other day, Stiles was talking to Lydia, and he’d mentioned how he’d thought that the new Superman actor was cute. Derek had to swallow down a growl, and he’d not-so-subtly changed into his Superman t-shirt afterwards.

Stiles didn’t seem to mind too much, or if he did, he didn’t say anything. He’d usually just laugh it off and give his husband a big hug, trying to calm him down.

This all came to a culmination when the water heater when out. 

“Der, I had to call a plumber to come fix the water heater,” Stiles told the werewolf. “He said he should be here soon.”

Derek just grunted from his spot on the sofa. He mindlessly munched on beef jerky as he watched TV, clad in just his sweatpants. He was so caught up in watching Alexander Skarsgård swinging through the jungle as Tarzan, that he’d barely heard the doorbell ring. 

“I’ll get it!” Stiles called out as he hurried over to the front door, swinging it wide open. 

“Hello, Mr. Hale,” a deep voice bellowed out, making Derek perk up, “I’m Chase, I’m here to fix your water heater.”

“Oh yes!” Stiles breathed, sounding relieved. “Come in, please.”

Derek turned around to stare down the other man who entered his house, frowning at the muscular stud who followed behind Stiles. The alpha werewolf couldn’t help but narrow his eyes in the direction of the plumber who wore a blue uniform. The young man was so built and muscular that he left the top three buttons of his shirt undone, showing off his impressive hairy pecs. His sleeves were rolled up, allowing his bowling ball sized biceps to curl out of them. In front of his tight jeans was a large bulge that made it look like the young man was smuggling a grapefruit in his pants. And when the plumber walked, his firm butt pressed tantalizingly against his jeans which were so tight that they rode a little low, giving credence to the term “Plumber’s Crack”. His dirty blond hair was combed in that style that made it look slightly messy, but sill manageable, and his lantern jaw was covered in masculine stubble. The dude seriously looked like he’d been ripped straight out of a porno.

Immediately, jealousy surged though Derek and he felt himself leap off the couch and hurry over towards Stiles, wrapping a possessive arm around his waist. He puffed out his own sizable pecs and forced a smile on his face. “Yes,” Derek almost growled, his voice rougher than intended, “please come into our home.”

Stiles shot him a look.

Chase only smirked as he entered the home, his heavy footsteps thudding loudly as he followed behind the couple.

“The water heater’s in the basement,” Stiles babbled on. “It went out last night and the water’s been ice cold ever since. You’re a real lifesaver for coming on such short notice.”

“It’s all part of the job,” Chase said, giving Stiles a crooked grin.

Derek bit down on his lower lip to hold back his snarl. “I could’ve fixed it,” he added hurriedly, “but I have a lot on plate since I run my own auto shop. So you know, management is very time-consuming work that only tough guys can do.”

“Wh-what?” Stiles wondered aloud.

Chase shrugged it off. “Sure,” he coughed. “A lot of wives tend to call me when their husbands can’t fix a simple appliance. It’s nothing to be ashamed about.”

Derek saw red and his fists shook with rage. He had to take a few deep breaths to prevent himself from phasing on the spot and mauling the cocky plumber… when a devious plan entered his head.

“It’s, uh, kinda hot down here,” he stated, forcing a toothy grin onto his face, “why don’t I get us some drinks.”

“I can get them,” Stiles offered.

“No!” Derek hurried, as he practically sprinted back up the basement stairs towards the kitchen. The werewolf tore through the cabinets as he grabbed three cups, making sure to grab Stiles’s favorite Superman glass. He then snatched the jug of Crystal Light out of the fridge before grabbing the secret ingredient from under the sink.

Derek couldn’t help but smile maniacally at the translucent powder that possessed a pink shimmer to it. It was a magical powder that Peter had made, claiming that it would cause “Embarrassing Side Affects that varied from person to person”. Derek had no clue exactly what that entailed, but he figured that annoying, sexy Chase would be the perfect tester to try it out.

The jealous werewolf made sure to pour Stiles’s glass first, setting it far away on the counter so that it wouldn’t come into accidental contact with the powder. That left two unmarked cups, and in his haste, Derek filled them both to the brim with the red Crystal Light. He then dumped a large spoonful of the mysterious powder into one of the glasses, marveling as it immediately dissolved, leaving zero trace of its presence behind. The giddy werewolf was so caught up in imagining all of the humiliating scenarios that played in his head involving Chase, that he put the jug of Crystal Light back into the fridge without memorizing which glass he’d spiked with the powder.

Derek froze as he stared at the two unmarked glasses on the counter, both of hem equally filled up with red juice. 

“Damn it,” he snarled, making move to dump them both down the sink to try again, but then something caught his ears.

The werewolf bristled as he heard Stiles’s laughter echo out from the basement, the deep bellowing of Chase’s annoying voice trailing behind.

With a ferocious growl, Derek dumped a spoonful of the powder into each of the unmarked glasses. He grabbed all three of them and raced back down the stairs, eager to break up the laughing session between the stupid plumber and his husband.

“H-hey, what’s so funny?” Derek asked, forcing a cheerful smile onto his face as he walked down the basement stairs. Despite his grin, his eyes narrowed in Chase’s direction. He walked up to Stiles and handed him the Superman glass that wasn’t spiked with the embarrassing potion.

“Chase here went to Beacon Hills High, too!” Stiles exclaimed. “I knew he looked familiar. We were in the same Spanish class.” He looked over towards the plumber. “You’ve put on some serious muscle.”

Chase held his head up high as he flexed a large bicep. “Yeah, I’ve been getting into bodybuilding,” he grunted. “You should check out my Instagram. I post tons of progress photos there.”

Over my dead body, Derek wanted to say, but instead he held out a glass for Chase. “Here,” he forcefully smiled, “I hope you like Crystal Light.”

“Thanks,” Chase obliviously said, accepting the glass and bringing it up to his full lips. He paused for a second, eying the water heater in the corner of the basement. “Oh, I can see a leak from here.”

“A leak?!” Stiles repeated incredulously, rushing forward to inspect the large machine as best as he could. “Where?”

Chase lumbered towards him, positioning himself way too close for Derek’s liking. “There,” he said, pointing towards a small spray of water.

For the millionth time, Derek was seeing red, beyond irritated that the muscleman was getting close and personal to his husband. In his anger, he briefly forgot that he was supposed to wait for Chase to take the first sip of his drink, and brought the glass up to his own lips to take a large gulp of the sweet juice.

Instantaneously, Derek’s eyes widened when he’d realized his mistake, quickly placing the half-emptied glass onto a nearby fixture. His heart raced in his chest as he waited for something to happen, holding his breath as he prepared for the worst.

“Damn,” Stiles frowned as he examined the leak, “do you see this, Derek?”

“Derek see,” Derek bellowed, his voice sounding much deeper and guttural than normal, making the werewolf flinch in shock. He had no idea why he’d referred to himself in the third person, so he cleared his throat and tried a second time. “Ook!”

Stiles only chuckled, his back still turned to Derek, thinking that his husband was just trying to be cute.

Meanwhile, Derek’s panic grew when he felt himself beginning to itch. He looked down at his chest and gasped as he watched wisps of black hair sprout all over his toned pectorals. The naturally smooth werewolf was stunned silent as he watched his hair thicken, and not just over his chest. He held his shaky hands up in front of his face, paling as hair grew over his arms, traveling towards his wrists and even his knuckles.

Derek felt his center of gravity rapidly shift, and he stumbled on his feet, falling over. He managed to catch himself before hitting the hard ground. Yet, he noticed that he was perched using his knuckles for support, reminding him of those lumbering gorillas he’d seen on TV. He tried to stand up straight on his two legs, but he could make it about halfway before toppling back down on all fours like an ape.

As a final touch, Derek nearly went cross eyed as he watched the bulge in his sweatpants steadily grow larger. The bulge inflated as it grew, causing his enlarged cock to stiffen and snake down his pant leg, looking ridiculously big on his toned, hairy form.

His heart raced in his hairy chest as Derek realized that he’d turned into some sort of monkey man. “Derek feel funny,” he muttered in his deeper voice, bristling at the awkward way he spoke. His thoughts were still coherent, but he couldn’t get his mouth to cooperate with what he wanted to say.

“Huh?” Stiles asked, looking over his shoulder before gasping at his hunched over, hairy husband. “Derek?! What the hell happened?!”

“Ook! Ook!” Derek bellowed, jumping up and down in his crouched position. His blush deepened when Stiles walked up to him, standing tall above his hunched over body.

Chase only glanced over this broad shoulder before shrugging and continuing to examine the water heater.

At the sight of Chase’s glare, Derek felt his possessive side spark once more. However, instead of silently brooding, the werewolf felt himself puff out his hairy chest. His muscles tensed, he beat at his chest with both of his meaty fists, mimicking a large gorilla. Again, he internally winced at his uncontrollable actions, but he couldn’t help it. Derek could only bare his teeth as he beat his chest intimidatingly.

Stiles’s eyebrows lowered slowly as he put the pieces together gradually. “Ohhh,” he hummed, eying the glass of Crystal Light.

Derek stopped beating his chest and cheekily smiled up at his husband. “Ook!” he grunted, nuzzling against the other man’s leg in an attempt at an apology.

Stiles snickered a little bit. “You’re silly, Derek, you know that right?” he chuckled as he ran his fingers through Derek’s hair.

“Ook! Ook!” Derek happily cheered as he bounced in place, his hard cock bobbing up and down wildly in his sweats. It wasn’t his intention to turn himself into some feral caveman, but he couldn’t deny that he liked how Stiles was paying much more attention to him now than he was to Chase.

“Your husband’s weird,” Chase muttered, rolling his eyes at Derek, who only beat his chest in uncontrollable response. The muscled plumber finally brought the glass of red Crystal Light up to his lips, taking a loud gulp.

“Ook!” Derek grunted as he watched the changes happen automatically.

Chase must not have felt anything, but as he drank down the cursed drink, Derek and Stiles stared in awe as the large bulge in front of his pants shuddered before growing less prominent. The previous mound that had looked like a grapefruit grew smaller and smaller by the second until the front of Chase’s jeans were flat and unremarkable.

When the glass was empty, Chase lowered it and wiped his lips. “This tastes kinda funny,” he said, freezing up in fear at the sound of his voice. His usual deep baritone was gone, replaced with a cartoonish voice that was hilariously high-pitched and squeaky, sounding just like a chipmunk’s.

Stiles had to cover his mouth to keep from bursting into hysterics.

“Oook! Ook!” Derek bellowed, happily slamming his fists down onto the ground in victory. He couldn’t hide the dim smile that stretched out his face, and he puffed out his hairier chest with pride.

Chase blushed a little and cleared his throat. “Um, *ahem, what I meant to say, *ahem, what’s wrong with my voice?!” The muscle man clutched at his throat, his face burning red at the sound of his cartoonish voice.

Stiles, unable to contain himself, broke down and doubled over with laughter. “That’s not it!” he guffawed, tears welling up in his eyes at the sight of the squeaky-voice muscleman.

“What do you mean?” Chase squeaked, stomping his foot in irritation, his voice making it sound more like he was throwing a tantrum than trying to be threatening.

“Tiny!” Derek managed to say, bouncing up and down excitedly on his feet and fists, like a chimp at the zoo.

“‘Tiny’?” Chase repeated, still blushing over the sound of his new voice. His eyes followed the direction of Derek’s stare. He gasped when he saw the flat front of his jeans and immediately unbuttoned his pants, shoving them down. The pathetic two inch nub looked completely out of place on Chase’s muscled frame. It was so small and puny that it was barely noticeable in his trimmed bush.

Chase screamed, his voice sounding even higher than before. He yanked his pants up and ran up the stairs in a hurry, exiting the house in a panic.

Stiles continued to laugh for a few more minutes before he was able to slightly contain himself. “That, haha, wasn’t nice Derek,” he tried to frown, but his chuckling ruined the mood he was trying to portray.

Still, Derek hung his head in shame. “Derek sorry,” he muttered in his slow voice.

Stiles smiled down at his husband and ran an admiring hand through his thick hair. “It’s okay, I guess,” he hummed. “You don’t have to be so jealous, Sourwolf. I love you.”

At this, Derek felt himself perk up, his lengthened cock rocketing to attention. The caveman werewolf beat his hairy chest with pride, a wide smile on his dim face. He then reached over and tossed Stiles over his shoulder, carrying him upstairs towards their bedroom as he readied to show his husband just what a wild man he now was.

31 Days of Derek Hale

Day 16: Himbo

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16

Derek Hale sat in the corner of the bar, brooding over life in general. The sourwolf had a deep frown set onto his face, scowling at nothing specifically— his foul mood creating a dark aura about him.

He finished his whiskey on the rocks and was about to ask for another one, when the bartender (some peppy guy with dyed blue hair) set down a large glass of beer in front of him. The golden drink must’ve been extra-carbonated because tons of tiny bubbles floated around like crazy in it.

Derek cocked his eyebrow up at the bartender. “I didn’t—”

“It’s on the house,” the bartender interrupted him. “It’s a new brand called ‘Bubbly Beer’.”

“‘Bubbly Beer’?” Derek repeated incredulously, almost scoffing at the stupid sounding name. The tough alpha wouldn’t be caught dead drinking such a ridiculous drink. 

Still, free was free.

Shrugging his shoulders, Derek brought the glass to his lips and took a tentative sip of the bubble-filled beer. It was sickeningly sweet and the carbonation made the drink more akin to soda than actual beer.

Derek grimaced at the drink, nearly gagging. He hated sweets.

However, the alcohol content must’ve been high, because after that singular sip of beer, Derek could already feel a slight buzz. His brain felt a little foggy and it actually seemed to dull his angst.

“Meh,” he hummed. “Does the trick, I guess.”

Derek took another sip.

The fog settled in deeper, and a dazed grin formed on Derek’s face. He leaned back further into his chair, unaware of the knowing smirk from the bartender. He struggled to think back to what was bothering him in the first place.

He happily brought the glass back up to his lips, but this time he took a couple gulps of the beer.

Derek’s smile grew a little larger, but it almost subsided when he started to feel a little warm. Like a sudden total wave of heat crashing upon him, Derek suddenly felt incredibly uncomfortable. His white button down shirt was suddenly a bit too thick for his liking, and having it buttoned up all the way made him feel awkward, almost like he was wearing a large tent. 

In an attempt to gain some sort of ease, Derek reached up and undid the top four buttons of his shirt.

“That’s soooooo much better,” he sighed, his goofy grin coming back full force once he wasn’t completely covered. His toned pecs were slightly exposed to the cool air of the bar.

Derek took a few more gulps of the beer.

The legs of the chair groaned loudly as Derek squirmed around. His chest felt heavier and his arms kept colliding with his sides in a way that they hadn’t before… right?

Derek’s heart raced in his beefy chest for a moment, but he quickly shrugged his anxiety away as he glanced down at his meaty muscletits. His massive pecs were barely covered by the button down shirt that they strained against, his nubby nipples poking teasingly against the fabric. His large biceps bulged out of his straining sleeves, constantly bumping against pecs and lats, hindering each one of Derek’s movements. And lastly, the werewolf rocked back and forth on his humongous bubblebutt that strained his jeans to bursting, the big ass making it look like Derek was sitting on a bunch of cushions.

Derek caught a nerdy guy sneak a peek at him from across the bar, and he couldn’t resist lifting one of his big arms to flex a powerful bicep.

The nerd’s jaw dropped, yet he quickly recomposed himself and stood up, slowly heading over towards Derek.

Derek finished off the last of the bubbly beer, setting the empty glass onto the bar.

“Um, h-hey,” the small nerdy guy smiled at Derek. “What brings you here all alone?”

Derek smiled back full force at the other guy, his cock rocketing to life. The ten inch monster snaked down his pant leg noticeably, looking like he was stuffing a summer sausage down his pants.

“Oh y’know,” Derek chirped back, “I’m just, like, totally out here looking for cute guys!” He giggled at the end of his statement, biting down on his lower lip as he ran his eyes up and down hungrily over the nerd’s body.

The nerd smiled back nervously, nearly drooling over Derek’s bulbous muscletits. “Well,” he said, “I’m about to ditch this place, if you wanna come with?”

“Sure!” Derek quickly said, practically hopping out of his chair. He snatched a tight hold of the smaller guy’s hand and began to walk towards the exit.

Derek paused for a brief second, feeling as if something was wrong. His gait was thrown off by the constant jiggling of his bubblebutt behind him, and he had to arch his back slightly to account for his huge pecs. Plus, his head felt so slow.

And he was so painfully horny! 

Despite himself, all he seemed to be able to focus on was cock and getting his big butt stuffed full with the nerd’s. His lust took over and that foggy sensation clouded over his brain again, effectively silencing that alarm bell. 

“Like, this is totally gonna be the best night ever!” Derek cheered as he wiggled his hips, causing his big butt to bounce wildly, loving the lustful look in the nerd’s eyes.

Day 17: Nippleslüt

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17

Alpha Derek Hale was taking a shower, a little irritated that he was rock hard and his husband was working the nightshift. Normally whenever Derek got a little frisky, he was all too happy to rush over to Stiles and go to town. However, he was a little miffed that he was all cocked and loaded, yet he was stuck all by himself with just his hand.

“Damn it,” Derek growled as he pumped away at his throbbing cock, even using some of Stiles’s shampoo to help do the trick.

Still, jerking off just failed in comparison to actually fucking. 

Derek was about to just give up and turn the water to ice cold when he spotted an unknown blue vial in the shower. Picking it up, he eyed it and read out the chicken scratch writing on the label that read out Liquid Lust. 

“‘Liquid Lust’?” Derek scoffed, rolling his eyes at his husband’s antics. Stiles had been practicing potions with Deaton, and every so often, Derek would find remnants of his experiments around the house.

Still, wanting to encourage his lover’s endeavors, Derek opened the vial and sniffed at the concoction. It reeked of musk, making the alpha gag and flinch.

Unfortunately, Derek’s jerky movements caused him to lose grip of the tiny vial in the shower, leading it to falling out of his grasp.

“Fuck!” Derek huffed as the smelly liquid fell out of the bottle and landed all over his hairy chest. It splattered across his pectorals, seemingly absorbing straight into his skin. The musky aroma clinging to Derek like it was emanating from him directly.

Immediately, Derek felt his nipples go hard. The little nips perked up before actually stretching out and elongating, inflating until they were large and nubby, looking like a pair of thumbs attached to his chest.

“What the hell?” Derek gasped as he looked down at his altered nipples. He tentatively reached up with one of his hands to prod at them. “What kind of potion is this— OOoohhhh!”

Merely grazing his fingers against his enlarged nipples sent a ripple of pleasure throughout Derek, his voice breaking out into a moan as his knees buckled. His cock throbbed even more, leaking precum. It was like a surge of pleasure never felt before. No amount of sex or jerking off had ever felt nearly as good as just touching his nipple just had.

“Wha-what the fuck is going on?” Derek panted, his meaty, hairy pecs heaving up and down as he struggled to catch his breath. His nipples seemed to burn with want, their own hardness competing with his cock’s, demanding attention from the alpha.

Almost unable to control himself, Derek reached up with both hands, running his thumbs over his hard nubs.

“Uuugghhh!” he squealed, his head rolling back as he toyed with his chest. The pleasure was mind-numbing, and Derek was helpless to do anything besides rub his nipples.

This soon turned to him grabbing a strong hold of both of them with his hands, lightly tugging on his huge nipples. It felt as if Derek had two cocks on his chest, his ignored dick bobbing uselessly between his meaty thighs as he pinched his big nips.

“Oohh fuuuck,” Derek bellowed out, the normally silent guy unable to stop moaning loudly, his deep voice echoing throughout the bathroom. “Holy shit, that feels so good— UUGHHH!”

Derek nearly shrieked as he came, his cock erupting and spewing out globs of cum that splattered against the linoleum in the shower. Basking in the post-orgasmic bliss, the werewolf felt as if he’d just shot the largest load of his life. He couldn’t help but chuckle in disbelief as he tried to catch his breath.

“Holy shit,” he breathed, rinsing away his cum off the walls. His nipples remained perky and hard, and after masturbating by tugging on them once more, Derek finished his shower and toweled off.

He wiped the steam away from the mirror and frowned when he saw that his nipples were still huge and hard. They poked noticeably off his chest, looking ridiculous on his muscular, alpha male frame.

“Um, maybe this’ll wear off in the morning?” he guessed as he glanced at the vial of the liquid lust, finding no other information about it on the bottle. 

Derek stumbled over to his bedroom, biting down on his lower lip at the shiver that traveled down his spine as the cool air from the A/C blew over his hairy chest, caressing his hard nipples. Just that light sensation was enough to make his cock begin to stir back to life, but he tried to ignore it.

He walked over to his shirt to try to cover his chest, but that proved to be another problem.

“Uuughh!” Derek moaned out again as soon as he tugged his shirt on. His nipples poked against the fabric like crazy, and just the cotton running over the nubs was enough to cause his cock to go erect and shoot out cum.

Derek had to rip the shirt away off of him, panting as he gained a reprieve for his sensitive chest. “What the fuck’s happening to me?” he gasped, his nipples almost simmering in the air as they begged for his attention some more.

That night Derek barely got any sleep at all. He would try to lie down on his back, but whenever the covers brushed up against his hard nipples, he’d go rock hard and have to tug on his nips to ease his horniness. Whenever he tried to lie on his front, it led to the alpha uncontrollably squirming against the mattress, moaning loudly as he ground his chest against the hard mattress, loving how it felt to rub his nipples against it, but also humiliated over what a huge nippleslut he was turning into.

“What the fuck am I supposed to do with these?!” he roared in frustration, looking down at his big nipples. 

When morning came, Derek was slightly relieved to hear the front door opening, meaning that Stiles had come home.

Derek leapt out of the cum-covered bed and raced downstairs to his husband, eager for some answers.

“Hey, Der— what happened to your nipples?” a tired-looking Stiles asked from the entryway once he saw the large nubs attached his husband’s muscled chest.

Derek gestured down at his nubby nipples with a shaky hand. “I accidentally spilt some of that liquid lust potion of yours on them, and now they’re— this! And they’re super sensitive!” he growled, his cock already starting to twitch at the mere thought of playing with his chest again.

Stiles’s eyes widened. “You messed with my potion?” he gasped in shock. “That was just a test. I don’t know if there’s a cure for it.”

Derek paled. “So I’m stuck like this?” he asked, looking down at his hard and sensitive nipples, imagining a life where he’d have to walk around constantly shirtless with his massive nubs on display. They’re so sensitive that he seriously doubted that he’d ever be able to get off again without someone playing with his nipples.

Stiles frowned for a moment before offering a meek smile. “If it helps,” he said, slowly reaching up, “I could play with them, if you’d like?”

He reached up and ran his thumb over one of the nubby nipples, and Derek instantly swooned.

“Ooohhh,” he moaned, his cock going straight to attention. “P-please, play with them some more.” He leaned forward and shoved his chest towards Stiles, looking forward to spending the day having Stiles play with his enlarged nipples, the nubs already tingling with anticipation.

Day 18: Cockgrowth

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18

Derek was an alpha werewolf, and with that, he was seen as the epitome of lupine masculinity. He towered over the other male werewolves in his pack and his muscles were always larger, more so due to his alpha genetics. He couldn’t help but also be turned on by the incredible size difference between himself and his boyfriend, Stiles. Derek was almost two feet taller and almost twice as wide muscular-wise. Derek Hale was an alpha through and through, with one tiny exception.

Derek’s cock was only four and a half inches.

Being below the national average for humans, Derek was humiliated over his subpar size. Over time, he’d fallen into the trope of being the big, mighty alpha who would pick on the smaller guy as a means of compensation for his size. And he’d counted himself extremely lucky that his boyfriend, Stiles, had been a virgin when they’d started dating, and therefore wasn’t really aware of the fact that his boyfriend’s dick was only about one inch away from being considered “micro”.

“Babe, do you think I’m small?” Derek frowned one night, looking down at his tiny dick that barely tented out his boxers.

Stiles, oblivious to his boyfriend’s inner turmoil, simply shrugged. “Don’t worry, Derek,” he’d smiled. “You’re the perfect size for me.”

“That’s not what I asked…”

One night, Derek had seen a mysterious Internet ad that promised “Significant Penile Growth” through some expensive pills. Desperate, Derek had immediately grabbed his credit card and ordered the pills. Once they arrived to his house, Derek wasted no time in ripping the package open and swallowing down a few of the tiny, blue capsules.

After swallowing the pill, it didn’t take long for Derek’s tiny cock to go rigid. The pert little thumb was rock hard, feeling as if Derek was harder than ever. His cock throbbed like crazy, and the werewolf barely registered any thought before his hand traveled south to wrap itself around his small cock and begin jerking off.

Derek couldn’t help but moan loudly as he toyed with his hard cock, his brain going numb from the pleasure that ripped throughout his muscled body.

Suddenly, Derek felt his fingers steadily start to be pushed apart.

“Huh?” he wondered aloud as he looked down at his cock, his eyes widening at what he saw.

As his cock throbbed, right at the pinnacle of hardness, Derek’s cock grew in both length and girth. As Derek jerked off, his cock would throb and jut further away from his body, gradually growing thicker by the second, causing his grip to loosen.

“Holy shit!” Derek cried with glee as his cock grew. “It’s growing!”

The alpha beamed as he witnessed his little cock go from four and a half inches to five, then six, seven, and eight. It thickened up from thin to the girth akin to a soda can, looking large and powerful— just as an alpha’s should.

But then it kept growing.

“Uh, th-that’s enough,” Derek muttered as his cock grew past the nine inch mark, his head almost purple from how hard he was. Precum started to drool out of it like a leaky faucet, and its sensitivity seemed to grow in intensity as did its girth.

Not to be outdone, the alpha’s balls grew in size as well, lowering and thickening to the size of ripe lemons. The thick size of his quads forced Derek’s newly enlarged package to be thrusted forward, his enlarged cock starting to look more like a third arm.

Derek could no longer keep his fingers touching each other, his girthy new cock becoming too large. He had to use his other hand to grip at it, his horniness overwhelming his panic as he jerked off his enlarged cock with both hands. It continued to grow to enormous proportions, finally passing the thirteen inch mark when—

“Uunnghh!” Derek squealed as he came, his muscles tensing up. His huge balls spewed out a large amount of cum, spraying all over the bedroom. It was significantly more than he’d ever came before, cum splattering everywhere at his feet and creating a mess.

It was such an intense orgasm that Derek was left panting, struggling to catch his breath. His meaty pecs heaving, Derek had to press his hand against the wall to steady himself. Finally softening, his mighty cock dangled past his knees, ridiculously long and thick, much past any reasonable proportions.

“What am I supposed to do with a dick this big?” Derek panicked, his eyes wide as he stared down at the massive anaconda that was his cock. Having spent so many years on the other side of the spectrum with a tiny cock, Derek was starting to feel apprehensive about having a cock that was too big… if that was even a thing.

His heart raced in his chest as Derek tried to think of ways he could even get dressed with a cock as big as his was now. There was no way he could manage to fit it into his pants, and even if he could, his huge cock and balls would press against whatever fabric dared to conceal it; its outline would be noticeable to anyone he passed by on the street without a doubt. Images of himself walking around in public with his swinging monster cock flickered into his mind, making him blush with humiliation. At least with his tiny cock, no one could see the outline of his dick through his pants. Now he doubted that any of his pants would even fit him in the first place!

Derek’s shaky hand gave his newly enlarged cock a tentative poke, and his knees buckled at the tidal wave of pleasure that rippled through him at that mere touch. “Oohh,” Derek moaned loudly as his cock rocketed to its full thirteen inches again, looking as thick as his muscular forearm. His head seemed as large as an apple, and it flushed as his cock throbbed with want all over again.

As Derek worried about his new girth, he didn’t hear Stiles walk upstairs and enter the bedroom.

“Hey, Der, can I borrow your chapstick— holy shit!” he gasped in utter shock when he saw the sheer size of his boyfriend’s cock. He wouldn’t admit it aloud, but the first thing that he thought was that there was no way he’d be able to fit that thing inside of him.

“Oh, uh,” Derek blushed, his enormous cock throbbing in front of him. When he turned to the side, it was so large that it knocked over some of the objects on the nightstand, causing them to clatter loudly to the floor. “I just took a pill that said that it’d make me bigger, but I think it worked a little too well.” Despite his panic, Derek’s hard cock twitched as he looked over at his boyfriend, the thirteen inch monster aching with intense want.

“I, uh, I see that,” Stiles mumbled, unable to look away.

Derek scratched at the back of his head nervously. “Do you think you could help me out with this?” he asked, gesturing down at his massive cock. “It’s a bit unwieldy.”

“I don’t think that’ll fit,” Stiles admitted, “but I could try to jerk it off for you?”

Derek took what he could get, and hurried over towards Stiles, his giant cock bobbing wildly in front of him with every step. 

Stiles reached over and grabbed Derek’s large cock with both hands, loving how Derek’s head rolled back as he moaned with pleasure. Thanks to its exaggerated size, Stiles couldn’t wrap his hands around it all the way, so he was left to gripping it as best as he could, having to jerk it off with both of his hands. The head was much too large for Stiles to suck on, but he still leaned forward and playfully ran his tongue over the head, pausing to flick his tongue over the sensitive slit.

The whole time, Derek was rendered a lustful mess. He couldn’t prevent his loud moans from echoing throughout the bedroom, his large cock being extremely sensitive. His eyes rolled to the back of his head, and all of his thoughts turned to mush as he was pleasured. His boyfriend’s hands on his dick was brining much more pleasure than any sex that they’d ever had before, and already Derek was thinking of how his sex life would be different. Given his cock’s new massive size, he knew that he’d be rendered to being jerked off or rutting against Stiles from now on, or even bottoming every now and then.

Derek tensed up as he came, blowing the largest load of his life, leaving him spent and panting. The force of his orgasm left Derek leaning against the wall as he tried to catch his breath. “Damn,” he breathed, “that’s new.” The alpha werewolf’s large cock dangled soft past his knees once more, and as his head started to clear, all he could think about was how much more of an alpha he must’ve looked like given his enormous cock that easily out-sized any other alpha’s.

31 Days of Derek Hale

Day 19: Action Figure

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18 │ 19

Derek rubbed his temples in irritation as he wandered through the numerous aisles of the toy store. Aisle after aisle, row after row, brightly colored advertisements and countless useless objects with stupidly high price tags made his headache even worse.

Derek had come to the toy store to find a gift for his boyfriend, Stiles… who he had to point out was a legal adult. Stiles was just a total kid at heart and loved to collect tons of franchise memorabilia, which was something that Derek loved about him. And after falling for the whole “Oh, you don’t have to get me anything” trap last year and having to deal with the fallout, Derek was determined to get Stiles the perfect gift this year.

“Damn it,” Derek growled at the memory of Stiles giving him the silent treatment after his non-gift last year, quickening his pace as he stomped through the aisles in search of something great.

Unfortunately, Derek was having no luck.

“Fuckin’ finally,” he repeated under his breath as he entered an aisle chock full of superhero action figures. 

Derek hurried down the aisle, his eyes scanning the rows of plastic men all over. Each one of them was brightly colored in blaring blues and radiant reds, their over exaggerated muscles looking extremely round and out of the realm of anything humanely possible. Derek’s trademark frown deepened as he searched all over the aisles for the perfect one.

No ordinary superhero would do, especially since Stiles already owned so many. Derek shuddered at the thought of accidentally buying his boyfriend one that he already owned, just to get the side eye and accused of not paying attention.

“Damn it,” the werewolf repeated, annoyed. He frantically began to search the aisle, picking up toy after toy and holding it close to his face studiously. Sure, they were all painted colors and had a variety of “[Insert Random Item]-Man” across the box in bright, blocky letters. However, Derek couldn’t seem to remember which ones Stiles already owned.

In his panic, the werewolf grabbed a white box that contained a blank action figure in it: no facial features or costume painted on at all.

The second his fingers grazed the mysterious box, Derek winced at the odd spark that traveled throughout his body, causing the hairs on the back of his neck to stand up. 

“What the hell was that?” he muttered as he brought his hand up to his face to examine his still tingling fingers.

Derek’s eyes widened as he witnessed his fingers taking on a shiny quality. He scrunched up his face in confusion as his fingers gleamed more underneath the bright fluorescents of the toy store. His heart raced in his chest as they stiffened, becoming immovable as his hand apparently turned into plastic.

“Wh-what?!” Derek panicked as the strange transformation traveled down his arms. Weirder was that the werewolf swore that his muscles plumped up, becoming larger and much more exaggerated before they hardened into the same plastic quality as his hands. His signature black leather jacket vacuumed to his torso as his pecs widened and pushed outwards, becoming skintight. It then started to brighten as it went from slate black to royal blue. His jeans underwent the same changes, suctioning to his buffer legs as they brightened into a cartoonish blue that looked more apt on a superhero, not a regular guy wandering around the mall. Derek winced as his bulge seemingly shrank as it was pressed tightly against him. Derek painstakingly move an almost inflexible arm and patted at his groin, groaning as it felt flat and unremarkable like a Ken doll.

The tingling sensation spread up to Derek’s head, and the altered stud couldn’t help but try to reach up with his plastic limbs. His hair had hardened into a large plastic mold, becoming a lump of black plastic in the shape of his usual hair style. His face felt smooth and unblemished, and he couldn’t help but press both of his hands on either side of his head and give it a little squeeze.  Derek couldn’t hold back his gasp as his head squished and then popped back into shape, illustrating that it made completely out of rubber now.

The werewolf tried to run off, to seek help, but he was stopped by his massively hindered movement. Like most action figures, his limbs were stiff and rigid, their over muscled selves only posable at the main joints.

“Well, well,” hummed an irritatingly familiar voice, “that’s a nice look there, Derek.”

Derek struggled to turn around, his virtually immobile body and larger muscles making movement extremely tedious. He fought back a growl when he saw none other than Theo, the bratty chimera who didn’t hide his crush on Stiles.

The mischievous smirk on Theo’s annoying face was enough to clue Derek into the fact that he was somehow behind whatever was happening to him.

“What did you do to me?” Derek demanded, trying to threateningly stalk forward, but his posable joints made his movements awkward.

Theo shrugged his shoulders. “I was lookin’ for a birthday gift for Stiles,” he snorted, “and I know that he likes action figures, and for some reason he also likes you, so…” He gestured forward at Derek’s new plastic body. “And you’re just about done.” 

Theo snapped his fingers.

Derek felt as if his sense of gravity was thrown as he wobbled on his stiff legs. The shelves in the aisle seemed to grow taller and much larger. However, it quickly dawned on Derek that the store wasn’t growing— he was shrinking.

The werewolf was helpless to do anything besides get smaller and smaller, as his movements became harder and harder to create. Derek’s scowl softened and instead he held a stoic expression as his face hardened. Eventually, the former alpha werewolf had been turned into  ten inch tall super hero action figure, complete with big muscles.

“Perfect!” Theo laughed as he easily picked up the toy Derek, snatching the blank box in his free hand.

Derek inwardly screamed, but was helpless as Theo positioned his plastic arms in a manner that looked like he had his hands on his hips in a heroic pose. He was shoved into the box, and from his frozen position, Derek could barely make out the outside of his prison chasing colors to become bright and alluring. Unbeknownst to him, the outside of the box now read: Superwolf: the World’s Most Muscular and Cranky Superhero!

“Stiles is gonna love my gift,” Theo laughed as he walked action figure Derek over to the cashier.

The whole time Derek screamed at being turned into a toy, and he just hoped that Stiles would figure out a way to help him out… and another part of him hoped that Stiles would like his large superhero muscles.
