Day 23: Ghost Possession

Despite being a werewolf, Derek didn’t believe in ghosts. In his opinion, they were the cheap product of Hollywood trying to advertise uncreative horror films. He would scoff at the young adults who’d dared one another to sneak into McFadden Manor, only to hear them swear up and down that they’d seen a ghost. Lies, Derek figured.

Still, when Stiles had made up his mind to investigate the ghost stories surrounding McFadden Manor for Halloween, Derek had instantly jumped at the chance to tag along in an attempt to look brave and woo the hyperactive human. 

Unfortunately, Derek couldn’t hide the grimace as he walked through the deserted McFadden Manor. The abandoned mansion was the center of numerous spooky, Halloween-themed tales— all of them focusing on a mischievous trio of ghosts who liked to mess with unsuspecting people. The wide smile on Stiles’s face deeply contrasted with Derek’s scowl.

He eagerly held up an ancient-looking camera. “We should split up and cover more ground,” he said. “I’ll go down towards the garden while you inspect the bedrooms. Radio me if you see anything.” He shoved a large, dinosaur era walkie talkie towards the werewolf.

“I can just text you…” Derek muttered, studying the heavy tech in his hands.

“Thanks for coming with me again, Der,” Stiles said, offering the usually grumpy werewolf a sincere smile, making the alpha’s heart flutter in his chest.

In response, Derek puffed out his muscular chest with pride, his pecs pressing teasingly against his thin, white t-shirt. “S’no problem,” he grunted, trying to play it cool, but he could feel his cheeks grow hot as he blushed. Plus, he couldn’t help but crunch his stomach to make his abs pop against his shirt too, his muscular bod being his best form of flirting since he wasn’t really good at wooing orally.

Stiles happily ran down one of the dark hallways towards his destination, Derek not-so-subtly watching his perky butt as it disappeared.

“Damn,” Derek admired before frowning at the sight of the decrepit mansion. “Damn it.”

Frowning again, he shrugged his broad shoulders and lumbered throughout the dark, cobweb-filled halls. To humor himself, Derek sniffed at the air, smelling nothing in the air except for dust and rats. He rolled his eyes at himself participating in this foolish activity, yet, he forced himself to focus on the endgame: Stiles and him getting together… and then heatedly fucking in his Camaro.

That last thought put a little more pep in Derek’s steps as he explored the empty rooms in the mansion.

*Thud!

Derek tensed up at the sound that echoed out from one of the bedrooms. Following the source, Derek entered a room near the end of the hallway. The room turned out to be a bathroom, the rusty toilet giving it away. There was a dust-covered sink with a dirty mirror near the entryway, and in the far end was a standing tub with a yellow curtain closed over it.

Derek cocked his eyebrow in confusion over the fact that the water seemed to be running in the tub, steam even billowing out from the curtain.

“What the hell?” Derek wondered aloud, knowing that there was no way this house was occupied given its dilapidated state. Still, the running water left the werewolf deeply confused. He grabbed the edge of the shower curtain and ripped it to the side.

Inside of the tub was a portly bluish figure that was slightly transparent. Looking like a caricature ripped out of a cartoon, the ghost had a little tail that seemingly phased in and out of existence as the creature showered. When it noticed that it was being watched, the ghostly figure looked over at Derek and gasped, covering its lower half with its hands… despite there being really nothing to see.

“Do you mind?” the ghost scoffed.

Derek was stunned silent for a moment, his eyes wide as he stared at an actual ghost that was floating before him. “Holy shit,” he finally breathed. “You’re a fuckin’ ghost!”

The ghost exaggeratedly rolled its eyes at Derek. “No shit,” it huffed in a baritone-filled voice that only emphasized its rotund girth. A sly grin formed on its translucent face and its eyes sparkled. “You know, most fleshies tend to avoid this place because of me and my brothers, but here you are.” He sniffed at the air, his smile growing wider. “A werewolf?”

Derek flinched and took a cautious step back.

The ghost continued. “We don’t get a lot of your kind here,” he chuckled. “Your bodies tend to be a little more sturdy. This should be fun!”

The ghost lurched forward at lightening speed, much faster than Derek’s werewolf instincts could react. Since his jaw was still hanging low in shock, the ghost aimed right for the alpha’s agape mouth. 

Derek felt his mouth being stretched to the limit as the ghost squeezed himself inside of him. It was a difficult sensation to describe. Thanks to the ghost’s vapor-like body, it felt as if there was a gust of air that was keeping Derek’s jaw thrusted down as it shoved itself in. Cartoonish stretching noises, like rubber, sounded out as the ghost entered the werewolf. Derek felt himself getting fuller and fuller, feeling as if he’d just eaten a multi-course meal and was stuffed to the brim.

With a simple pop, the ghost finished his entrance and successfully squeezed his rotund body deep inside of Derek.

The werewolf felt full, his stomach and even lower end of his throat feeling as if there was a thick soup trapped in it. Derek stumbled around on shaky feet, trying to piece together what had just happened. The ghost squirmed a little as he settled in under Derek’s skin, the werewolf wincing at the sensation. 

“Damn, I can’t believe that worked!” Derek heard himself exclaim. “I usually have trouble fitting inside tiny bodies.”

Tiny? Derek balked.

Derek’s tingling limbs appeared out of his control, and the more Derek tried his best to strain and walk on his own accord, the more horrified the werewolf grew as it dawned on him that he wasn’t in control of his body. He even attempted to open up his mouth and demand that the ghost leave his body, but he couldn’t even do that— instead, Derek was more so a passenger inside of his own body. He could still experience every sense, smelling and feeling everything around himself, but he couldn’t move or speak on his own.

He felt his legs propel him forward, turning around to look into the mirror. Derek bristled at his own reflection which only smiled back at him, his smile eerily similar to that of the ghost’s.

What the fuck are you doing to me?! Derek roared on the inside. Get the fuck out!

The ghost only shook Derek’s head mockingly. “No way,” he said, making Derek’s body and voice say it on his behalf. “I kinda miss having a body so I’m gonna hang onto yours for a bit. The name’s Fatso, by the way.”

That’s a stupid name.

The ghost shrugged. “And this is a stupid body,” he countered, exploring Derek’s body, running his hands over it. Derek could feel every touch, unable to stop feeling himself up. “There’s barely any room inside of here. Let’s fix that.”

Derek screamed on the inside as he witnessed his stomach shudder before it expanded outwards. His gut grew in size and it rounded out as Fatso forced it to bubble out. Derek’s chiseled abs disappeared as a thick layer of fat appeared over them, going from firm to large and jiggly. It grew bigger and bigger, becoming huge and bulbous as it jutted far out in front of Derek, looking as if he’d swallowed a yoga ball instead of a ghost. To add to the inflation, even Derek’s pecs packed on some fat. They lost some of their tone as they grew larger and saggier, resting atop his enormous belly. There was still some traces of Derek’s large muscles underneath his new girth, but instead of looking like he lived in a gym, he looked more like some ex-jock who was in the middle of a perpetual bulking phase.

What the fuck did you do to me?! Derek roared on the inside, wincing as he examined his new body in the mirror. He must’ve gained well over fifty pounds, with most of it centered on his new gut. His mysterious growth had torn his t-shirt to shreds, forcing him to see all of his girth at once. Despite looking hard and solid, Derek winced at the way his gut hung over his jeans, sagging slightly.

Fatso mock-frowned. “Don’t be like that,” he taunted, putting both of his hands on the sides of Derek’s new belly and giving it a playful shake, causing it to bounce wildly. “I think you look much better with some more meat on our bones. Now there’s some food in the kitchen that we can eat.”

Eat? You mean you want me to get even fatter? Derek protested, unable to prevent his body from waddling out of the bathroom and down the hallway. His thicker thighs rolled over one another as he moved, and his rotund belly stuck so far out in front of himself that he couldn’t even see his feet. He inwardly flinched every time his foot thudded against the hardwood floor, sending a ripple through his belly and pecs.

Fatso forced Derek into the kitchen, where he made him lumber towards the fridge. Derek was surprised that when it opened, it was stocked full of food that looked like it’d just been bought earlier that day as opposed to sitting for years untouched.

Derek felt his arms lurch forward, grabbing fistfuls of various treats and snacks. 

“The only downside to being a ghost is that you can’t eat a lot of food,” Fatso lamented. “But the good thing about possessing a werewolf fleshie is that you can gorge on tons and tons of junk food. Much, much more than a human can!”

No! Wait! Derek pleaded.

His pleas fell on deaf ears as Fatso eagerly shoved loads of food into Derek’s mouth, moaning loudly as he tasted all sorts of flavors. Salty, sweet, savory— all kinds of different foods were shoved down Derek’s eager throat, none of them low-calorie.

The entire time, the werewolf inwardly begged Fatso to stop gorging on so much junk food. However, the ghost was paying no attention to him, moaning loudly as he devoured everything in the fridge.

In the center of the fridge was a delicious looking, three-tiered cake with bright pink frosting. Derek could feel his mouth salivating as his eyes honed in on the monstrous dessert. 

Before Derek could uselessly plead with Fatso again, his hands grabbed at the cake as he greedily gobbled it down. All he could taste was the sugary frosting and the chocolate center of the cake, grimacing at the sweetness, yet Fatso loved it.

Derek inwardly froze when he felt something horrible: his pants felt like they were getting tighter.

It was hard to tell since Fatso controlled his line of sight, but Derek could barely make out his gut growing more and more into his field of vision. It didn’t take long for the werewolf to put two and two together to figure out that, thanks to Fatso’s overeating, he was getting even bigger.

His big belly was starting to jut even further away from his torso as it packed on even more size from the delectable cake. His pecs felt heavier as they grew in size, his nipples even stretching out from the sheer expanse of his enlarged chest. Love handles formed and drooped slightly over the edges of Derek’s pants, which felt painfully tight by now.

Pop!

The button on Derek’s pants finally gave out, ricocheting off and landing on the floor. Derek felt a sense of relief as he continued to fill out, his ass puffing out as his cheeks ballooned out and became large and squishy. To account for his larger rear, Derek could even feel his thighs starting to push closer together as they blew up. As Fatso continued to eat, Derek’s body went from bulky to chunky linebacker status, looking incredibly large as if two of him were shoved together into one body.

Fatso fit the last few bits of the cake into his mouth, swallowing it down loudly and straightening back up. He patted his large gut, satisfied, before letting out a loud burp.

“I always gotta get a big cake before every Halloween thanks to silly guys like you who want to come play detective,” he smiled, rubbing his hand up and down his distended belly. “This was nice. See ya next year?”

Derek let out another loud belch, this one accompanied by a flash of blue as Fatso left his body to fly somewhere else in the manor.

Finally in control of his body, Derek gasped loudly as he ran his shaky hands all over his enlarged form. For some strange reason, even with Fatso gone, Derek was left with his added weight, looking massive and round. He took an awkward step forward, blushing as his entire body seemed to jiggle. He couldn’t see anything past his large belly which definitely wouldn’t fit in any of his clothes anymore.

“Damn it,” Derek huffed, giving his gut a tentative poke. “I have to do so many crunches to get this down to size…” He trailed off when his stomach growled, a deep hunger taking over him.

“Hey, Der,” Stiles called out, his footsteps approaching, “still no sign of any ghosts. I’m starting to think that they’re just stories.” Stiles froze when he reached the kitchen, his eyes nearly falling out of his head at the sight of the fatter Derek.

“Um,” Derek blushed, scratching the back of his head nervously, “I think I found a ghost—” He paused when Stiles stepped forward and placed a soft hand on his rotund belly, rubbing it up and down.

A smile forming on his face, Stiles couldn’t help but look up at the large werewolf. “Do you like belly rubs?” he asked, playfully rubbing Derek’s gut.

Although he couldn’t see it thanks to his big gut blocking his view, Derek could feel his cock rocket to attention, already oozing as Stiles gave him a belly rub. “Y-yeah,” he breathed. He blushed again as his stomach growled a second time.

“Big boy’s hungry?” Stiles teased.

Derek just eagerly nodded, looking forward to eating cake and getting more belly rubs from Stiles. 

All in all, it turned out to be the best Halloween of Derek’s life.

Day 24: Cow

Derek grimaced as he swallowed down the odd tasting protein shake. “That tastes weird,” he spat. “What’s in it?”

Theo shrugged his shoulders. “It’s a new recipe I’m trying out,” he answered, smirking slightly.

The werewolf and the chimera had been trying to work more closely together, for the sake of the two packs in Beacon Hills. As a result, Derek and Theo would try to be more cordial with one another. One such activity that the two pack leaders actually didn’t hate to do together was work out at the gym. There was a sort of playful rivalry that the two engaged in, always trying to out lift the other as they worked out, trying to get more gains.

Being an alpha werewolf, Derek easily out lifted Theo and his muscles were way larger by comparison. The chimera, on the other hand, tended to stick with a more toned physique, not allowing any of his jealousy to show on his smiling face.

Which was why he was all smiles as he offered Derek a drink of his own secret concoction. The mischievous chimera had fought hard to hide his triumphant grin as he’d watched Derek take a hesitant sip of the “protein shake”.

Derek still wiped at his mouth with disgust at the horrible shake that Theo had offered him. “Yeah, I think I’m gonna stick to my usual,” he huffed. “Thanks though.”

Again, Theo shrugged. “Suit yourself,” he happily hummed.

The two men went to starting their workouts, Theo keeping a careful eye on Derek.

Derek, oblivious to the chimera’s staring, went to the chest fly machine, racking up a ton of weight before performing reps. As he worked out, he noticed an odd tingling sensation in his pecs that wasn’t like the normal burn that he’d expected. Instead, this one felt almost electrifying and oddly… good. Really good.

Derek blushed slightly as his chest tingled, his nipples feeling as if they were hardwired directly to his cock. His cock started to stiffen up in his shorts, and as he continued to perform reps, Derek had to hold back a moan.

“Mmmm,” Derek moaned as he tried his best to keep his lips pursed. His blush deepened when he looked over and caught Theo staring.

The alpha werewolf quickly diverted his gaze and tried his best to continue his workout.

Derek was trying so hard to ignore the odd sensations emanating from his pecs that he hadn’t even registered the growing tightness of his shirt until he heard a loud rip echo throughout the nearly empty gym.

He let go of the weights, letting them bang loudly back to the machine. Cocking his eyebrow, Derek looked down at himself, gasping loudly at the large pecs attached to his chest.

“M-my pecs!” Derek stuttered out of shock. “They’re huge!”

Staring downward, Derek’s previously proportional pectorals had been wildly inflated. They jutted out dangerously from his chest, looking round and bulbous. It looked like someone had sliced a soccer ball in two, glueing both halves onto the werewolf’s hairy chest, looking incredibly out of place on his muscular body. Worse for Derek was that his nipples had even enlarged, growing thicker and protruding off of his massive chest like nubby fingers.

Derek blushed when he squirmed in his seat on the machine, feeling how much his chest bounced and jiggled. Oddly, his pecs felt so heavy and cumbersome, and when he moved, he felt an odd sensation of something sloshing deep inside of them.

Theo snickered as he looked the top-heavy alpha up and down. “I’d say so,” he teased. “Those are some serious udders you’ve got there, Derek.”

Derek shoved himself away from the pec fly machine and hurried towards the privacy of the locker room. As he moved, he noticed the arched back stance that he had to take in order to accommodate for his inflated pecs. This caused the enlarged mounds to be thrusted outwards and more into the open, being impossible to conceal. They bounced and jiggled with every step the frantic alpha took, that sloshing sensation growing in fervor.

When he reached the locker room and stared into the mirror, Derek paled at his warped reflection. His pecs and nipples were huge, easily out-shadowing the rest of his impressive musculature, every other body group looking like an afterthought. His jaw dropped, resting upon the cresting pecs that were pushed upwards and out.

Theo, a devilish smirk still plastered on his face, sauntered into the locker room. He crossed his toned arms over his proportional chest as he studied Derek. “They don’t look that bad, Derek,” he snickered. “Maybe we can get you a bra?”

The color gradually returned to Derek’s face as he turned red, slowly putting the pieces together. “You did this to me?” he accused, gesturing down at his massive chest.

“Duh,” Theo scoffed. “I grew tired of always being the small one, so I did some research and found that a really good growth formula contains alpha milk. Hence, all I needed to do was get you to produce some.”

“‘Alpha milk’?” Derek repeated, looking down hesitantly at his large pecs, frowning when he couldn’t anything past their bulbous size.

Theo walked over and didn’t give the alpha any warning before he reached around and grabbed Derek’s meaty pecs.

“Oohhh!” Derek couldn’t help but moan as his muscletits were fondled. Despite his panic and frustration over having his chest altered, he couldn’t ignore the surge of pleasure that rippled through him. In addition to increasing in size, his pectorals also drastically increased in sensitivity. Every touch from the other man’s hands lit up pleasure receptors that Derek had never had before. His knees buckled and his head rolled back as he was felt up. No amount of sex or playing with his cock could ever compare to the brilliant sensations on his chest, and deep down, Derek felt himself craving more.

Theo began to thumb Derek’s nubby nipples, and the werewolf felt as if he’d explode at any second. His heavy pecs lurched and he felt that sloshing inside of them grow even more; and Derek swore that his pectorals began to feel slightly larger.

Derek tensed up, shooting his load. However, instead of cumming, his nubby nipples squirted out a white substance. The pressure in his muscletits subsided the slightest bit, but Derek felt something else bubbling deep within him. He tried to swallow it down, but the alpha werewolf couldn’t help himself.

As his nipples leaked, Derek bellowed out a deep, “Moooo!”

He was so caught up in the feeling of pleasure that left tingles all over his skin, especially his burning nipples, that Derek didn’t even have time to feel humiliated over that fact that he’d mooed like a cow.

Meanwhile, Theo strategically placed his bottle under the alpha’s leaky nipples, collecting the milk that had seeped out. Placing the cap on it, he grinned widely.

“We’ll have to do this more often, Derek,” he happily said. “There’s a lot of guys out there who’d give a fortune for some alpha milk so that their muscles can grow bigger. And just think, it’s all thanks to you and these udders of yours.”

Derek wanted to be angry, to lash out at the chimera for turning his pecs into large muscletits. However, Theo reached out and teasingly flicked a protruding nipple, causing a lustful haze to cloud over Derek’s mind.

“Mooo!” Derek bellowed again, his giant pecs jiggling with want.

Day 27: Hot Cop

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18 │ 19 │ 20 │ 21 │ 22 │ 23 │ 24 │ 25 │ 26 │ 27

“Well, well, if it isn’t none other than the infamous Derek Hale,” Sheriff Stilinski sighed as he sat down in the driver’s side of the cruiser. 

Derek just glared silently back through the fence-like barrier that separated the two of them. He huffed angrily through his nostrils, keeping his lips pursed to avoid making the situation any worse for him. The young man wasn’t unfamiliar with Sheriff Stilinski, often running afoul with the old man here and there. It wasn’t that Derek was a career criminal by textbook standards, but he admitted that he didn’t make the best choices. Thus, he had a sort of negative reputation around Beacon Hills, with most of the sheriff department keeping a watchful eye on him.

The cruiser’s engine roared alive, and the Sheriff drove down the road towards the station.

Derek silently steamed in the backseat, perfectly content with not saying a single word.

However, the Sheriff cleared his throat and eyed the werewolf in the rearview mirror. “You know, Derek,” the Sheriff said, his rough voice taking on a kind air, “I’d promised your family that I’d look after you. But for some reason, you just can’t seem to keep your nose outta trouble.”

Derek just grunted, rolling his eyes. He tried to tune out the cop and focus on the woods outside the window. 

The Sheriff continued though. “And,” he pressed, a different tone overtaking his deep voice, “I’ve seen you eying my boy.”

Derek winced and fought hard to maintain his cool, but he could tell that he looked worried as his bushy eyebrows knitted together. Of course he found the Sheriff’s son, Stiles, attractive and it was true that he’d been trying to court him; however, he hadn’t counted on the old man being that perceptive.

“What are you talking about?” Derek tried to play it off, his heart starting to race in his chest.

The Sheriff lowly chuckled. “Derek,” he said, clicking his tongue, “I have my own skills, too. And let’s just say that although I like you and your family, I’m not too happy to have someone like you following my son around.”

Being used to being seen as less, Derek snorted and prepared a sharp retort. However, when he opened his mouth, his eyes widened when no sound came out. He cleared his throat and tried again, but not matter how hard he tried, the werewolf couldn’t utter a noise. He felt his heart start to race in his chest as he tried with all of his might to make the slightest bit of noise. However, every single attempt was futile.

The Sheriff smirked back at the struggling werewolf in the rearview mirror. “But you don’t have a job right now, do you Derek?” he pressed, an odd happy quality to his voice.

“No, Sir,” Derek felt himself respond without thinking. He wondered what was going on— why he could only seem to speak when the Sheriff allowed him to, and why he’d called him ‘Sir’.

“That’s a shame,” the Sheriff added. “You were always so cheery and polite. I would’ve figured you’d be the star employee somewhere by now.”

Cheery and polite? Sure, Derek wasn’t a blatant asshole, but neither of those adjectives described him in the least.

“Thank you, Sir,” Derek heard himself reply again. “I always do try my hardest, but gosh darn, the job market is tricky.” The werewolf’s stomach fell as he heard himself speak in such a dweebish tone. He tried to force himself to cuss out the sheriff, but as soon as the words were almost on his tongue, they’d fled.

The Sheriff cleared his throat and went on. “Well, if you’re interested, the police academy is always taking in new recruits. I think you’d be a good fit.”

Derek wanted to decline immediately, hating the idea of seeing himself strutting around Beacon Hills as some police officer who acts all goody two-shoes and whatnot. “That sounds like an awesome idea, Sir,” Derek happily agreed, and he felt his face stretch out into a giddy smile. He spotted his own reflection in the rearview mirror and inwardly flinched at how dorky he looked being all smiles; however, his attention was quickly diverted when he noticed something else.

Derek’s eyes widened even further when he saw that his jeans and white tank top had completely disappeared from his body. As quickly as his old clothes had vanished, new ones reappeared in their stead. Navy blue khakis were tightly wrapped around his powerful legs, looking almost skintight and like there was barely any extra room in there. His torso had on a navy blue, button down shirt that had the patches of the Beacon Hills Sheriff Department sewn onto the short sleeves. Right above the right pocket was a small silver name tag that read out: “HALE”. A black belt appeared around his waist, equipped with all of his police equipment that he’d need for his new job.

Derek’s smile faltered for a brief second before it took over once again. “Thank you, Sir,” he grinned. “I’ve always wanted to be a cop ever since I was a kid.”

The Sheriff nodded. “I know it, Derek,” he hummed. “I can tell by the way you’ve dedicated yourself to fitness.”

Before he could ponder over what that meant, Derek felt all of his muscles tense up simultaneously. The first thing Derek noticed was his thighs steadily growing larger and rounder, closing the gap between them little by little. However, his line of sight was soon cut off by his growing chest muscles. His pecs inflated and pushed outwards, taking up the remaining room in his shirt until it was skintight— POP! The top two buttons of his police shirt popped off, revealing the new, deep pec cleavage he now possessed. His arms grew in size, his biceps inflating to the size of melons as they bulged with power out of his short sleeves. They rested on flaring lats, giving the werewolf a broad appearance that reeked of masculine power. When he looked back into the mirror, Derek saw his neck steadily broaden in tandem with his shoulders, effectively giving him the appearance of a bodybuilder in a police uniform. 

His heart raced in his inflated chest, but instead of voicing his panic, all Derek could say was, “That you, Sir. Last weigh in, I came in at three-hundred pounds of solid muscle— all for the good of protecting my community.”

The station came into sight and the Sheriff’s own smile dominated his older face. “That’s the right attitude to have, Derek,” he said. “I know you’ll be a great man of the law.”

Derek felt his old self starting to slip, quickly being dominated with the muscled Dudley Do-Right cop he’d been turned into. He grit his teeth to prevent the change from taking over, but it was futile. In a matter of seconds, the old trouble-making Derek Hale was quickly replaced with Deputy Hale: the bodybuilding cop who was as straight-laced as they came.

Derek’s smile grew even more, genuinely this time, as he noticed the station as the Sheriff parked in front.

Derek exited the back of the cruiser, unsure why he’d decide to ride in the back— he probably lost a dare and was playing around with Sheriff Stilinski. The older man was like a father to him, and Derek respected him with every fiber of his being. As soon as the new cop took a step out of the cruiser and felt his large thighs rub against each other and noticed how heavy his pecs and arms were, he cocked his eyebrow in confusion for a moment. Maneuvering around felt awkward, almost as if he was getting used to strutting around in such a muscled body.

Derek snorted and shook his head, knowing that was ridiculous. He worked out religiously and was always super muscled, easily dwarfing all of the other men on the force.

The muscled policeman waddled up to the station, but froze when he saw the Sheriff’s son, Stiles, hanging by the entrance. He felt his heart race in his beefy chest and blush form on his face over how cute Stiles looked. 

“Oh, um, h-hi there, Stiles,” Derek gushed, looking like some lovestruck dork in front of the station for all to see. “What brings you here?”

Stiles paused for a moment, his own eyebrows furrowing for a second. “I came to see my dad,” he mumbled, his eyes running up and down Derek’s bulging form, making the cop’s heart race even faster. “Derek, d-did you… um, this might sound weird, but you look different for some reason. I can’t put my finger on it.”

This time, Deputy Derek shared Stiles’s confusion, and for a flash, the way his body felt so heavy and the sensation of his skintight uniform on his muscles felt all too wrong. However, just as quickly as the feeling had occurred, it evaporated into thin air and Derek’s smile widened even more.

“I just got back from the gym,” he happily gushed, raising both of his powerful arms above his head to form a double biceps pose. The movement caused his massive biceps to curl completely out of his sleeves and bulge with power. “It’s probably the pump you’re noticing.”

Stiles blushed a little as he stared at Derek’s huge muscles. “Yeah, I guess that’s it,” he admitted.

Not wanting to waste any time, while still flexing, Derek blurted out, “Want to do something this Saturday?” he asked. “… with me? Please?”

Stiles wanted to argue, to say that something was definitely different about Deputy Hale. However, his memories seemed to recall seeing the muscled up cop working shoulder to shoulder with his father for quite some time. “Sure,” he finally agreed.

Deputy Hale dropped his arms, letting them rest atop his lats a near right angle. “G-great!” he eagerly stuttered, the giddy new deputy over the moon at the prospect of finally taking the Sheriff’s son out. “I’ll pick you up at seven!”

The host, Matthew Johnson, walked back onstage, eliciting thunderous applause from the crowd. He was a handsome man dressed in pristine white clothes that were tailored to tastefully show off his muscled body.

“Welcome back everyone to The Matthew Johnson Show,” the host smiled to the live studio audience. “We are continuing our series called ‘Living with Curses’. Just last week, we chatted with Scott, the man cursed to shrink down to only five inches tall!”

The audience roared with laughter at the memory of the pipsqueak Scott.

“But today,” Matthew continued, “we have another man here who’s been living with a curse for about two months now. And unlike Scott last week, this curse has caused this man to grow! Everyone, please welcome to the stage: Derek Hale!”

A stunned silence blew over the crowd as Derek Hale walked onto the stage… well, more like waddled onto the stage.

Derek Hale was a massive muscle monster! That was putting it lightly too, because the stud was insanely large. Almost as wide as he was tall, Derek looked like he was struggling to lumber around. His thighs were about as thick as the host’s waist, and they rolled over one another with every step the bulky man took. They pressed against each other, causing the man to have a wide stance. A bulbous roidgut protruded out in front of Derek, making him look almost pregnant with how massive it was. It was round and didn’t jiggle at all, indicating that there wasn’t a trace of fat on his over-muscled form. His pecs were huge and round, and they rested on top of his gut; large, nubby nipples poked noticeably against the tight t-shirt that struggled to contain Derek’s bulk. His back was wide and his shoulders were insanely broad, having to be large enough to carry his enormous arms. Biceps the size of Derek’s head tore through the tight sleeves of his shirt, pressing against his flaring lats that caused his arms to hang at ninety-degree angle.

Derek was so large that he made Matthew look puny by comparison. He was larger than any other bodybuilder that had ever been on TV, and he had such an enormous gut that it seemed to be the epicenter of his growth— being the largest part of him.

As he moved, the hunk breathed heavily and blushed bright red as the stage lights were on him, broadcasting his enlarged form to all of American daytime TV.

Matthew handed Derek a microphone, and the muscled up guest struggled to bend his massive arm enough to bring it up to his mouth, the movement causing his bicep to flex with power.

“Welcome to the show, Derek,” Matthew said. “Now, let me try to understand this: You weren’t this muscular two months ago, were you?”

Derek’s blush deepened and he shook his head. “No,” he grunted in a deep voice that was full of baritone.

On the screen behind the two men appeared a picture of Derek before he was cursed, showing off a toned man that was about a third the size of the swollen bodybuilder onstage.

“You where what, one-hundred eighty pounds in this picture?” Matthew pressed, gesturing towards the image on the screen. “And now you weigh how much?”

Derek took a hesitant look over at the audience, thankful that the positioning of the stage lights prevented him from making out any faces. He was beyond humiliated standing up on stage in his overgrown bulk, but after running out of ideas and failed spells from Deaton, it was his last hope at returning to his usual size.

“Um,” Derek mumbled nervously, “I weigh three-hundred seventy-nine pounds now…”

A loud gasp ran through the audience.

“And tell us, how did you get so big?” Matthew asked, placing a sympathetic hand on Derek’s broad shoulder. The size difference between the two made Matthew’s hand look utterly tiny.

Derek sighed loudly, the movement causing his massive shoulders to rise and fall, his shirt seams groaning at the movement. “I was at the gym and got into an argument with some guy,” Derek growled, anger written all over his face as he remembered what had happened. “Words were said, and I called him a ‘Roided-Up Freak’. Then he snapped his fingers, and well…” Derek gestured downwards at himself.

Matthew nodded quietly, and then perked up. “And I understand that your boyfriend, Stiles, has stayed by your side this entire time?”

The audience let out aww’s and coos.

Derek nodded as best as he could due to his huge traps swallowing his neck. “Yeah,” he said. “He’s… my rock.” He admitted it, his heart racing over how grateful he was for Stiles. 

Like Derek, Stiles had been freaked out too when Derek had turned into a roid-loving bodybuilder. He’d tried his best to find spells to turn him back to normal, or at least find clothes big enough to fit over his unwanted bulk. However, unlike Derek, Stiles quickly came around to his boyfriend’s new appearance. He would run admiring hands over Derek’s inflated pecs or marvel over how he couldn’t fit hit hands even halfway around Derek’s biceps… and despite being annoyed, Derek would be lying if he didn’t admit that deep down that he loved having Stiles worship his muscles.

However, despite how great life was with Stiles, Derek was still irritated over his bulky body ruining his life. He couldn’t fit in his prized Camaro anymore. His gut and pecs were too big and they constantly pressed against the horn. Plus, his back was so wide that he couldn’t even close the door thanks to how broad he was. Speaking of doors, it took all of Derek’s cleverness to squeeze himself through any standard-sized one. He always had to go through them sideways thanks to his broad shoulders, but it was always a struggle fitting his roidgut and pecs through the doorway. All of his clothes were now XXXL, and they always looked like they were painted on. Even sleeping was struggle too! Whenever he lied on his back, Derek’s huge back muscles kept his head elevated above his pillow. He couldn’t lie on his side, not with his large arms and lats. His gut and pecs were too big to try sleeping on his front. He had to position pillows and blankets carefully around his body in order to get comfortable. But his large body left zero room for Stiles, forcing the tiny human to sleep completely on top of Derek’s large muscles… but Derek secretly liked that part of the curse.

As the show went on and Derek answered the host’s questions, a loud ripping noise echoed out.

“Oh no…” Derek groaned as his shirt finally lost its battle trying to conceal his bulk. The collar split right down the middle of his pillowy pecs, traveling downward to his gut. His sleeves burst to shreds over his enormous biceps, leaving the large bodybuilder completely topless. Derek blushed, and then winced when he heard another loud tear, this time his huge glutes bursting through the back of his tight pants. Now that he was exposed, his vascular form was on full display, showing off the radiating veins all over his huge physique.

Matthew mock frowned, yet the audience erupted into a fit of laughter, making Derek blush even more.

“Well, Derek,” Matthew said, “we looked into your curse to see if we could help you at all. And guess what? We can.”

Derek perked up a little, hopeful at returning to his normal body after months of being trapped in an overblown, roided-up bodybuilder’s body. “R-really?” he asked, hopeful. 

Matthew reached into his back pocket and handed Derek a card. “Yes, Big Guy,” he smiled. “This here is a fifty dollar gift card to Mens’ Big and Tall. They have all sorts of styles designed specifically for large, bulky men such as yourself.”

Derek frowned as he snatched the gift card away from the host.

Matthew turned back to the crowd. “And coming up after our break, a man whose voice sounds like a chipmunk’s! That and more on The Matthew Johnson Show!”

Derek waddled off the stage, grumbling angrily to himself the whole time. He’d just embarrassed himself on TV for a stupid gift card. “I hope his shit show gets cancelled,” he muttered to himself as he walked backstage towards a waiting Stiles.

Stiles looked up at his inflated boyfriend sympathetically. “Sorry Derek,” he frowned. “I thought that it’d help. I mean, it looked like he helped people whenever I’d watch him on TV.”

Derek huffed and had to take a step backward so that his protruding pecs weren’t blocking his view of Stiles. “Yeah, who would’ve guessed that people lie on TV?” he rolled his eyes.

Stiles’s frown lightened up the smallest bit. “Well, I mean, if you are stuck as a big bodybuilder…” he led, looking at Derek with a hopeful expression.

Derek sighed, but forced a grin on his face as he lifted his muscled arms as best as he could, forming a double biceps pose. “Wanna feel, Little Man?” he asked the usual line that had become a staple in their bedroom activities.

Stiles’s smile grew. “Yes, please.”

Derek couldn’t help but smile back, reaching over and tossing Stiles over his broad shoulder with ease. “I could get used to this, I suppose,” he shrugged to himself as he waddled off, loving how small his boyfriend felt against his bulk.

Day 29: Butt Growth

Info │ 01 │ 02 │ 03 │ 04 │ 05 │ 06 │ 07 │ 08 │ 09 │ 10 │ 11 │ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │ 18 │ 19 │ 20 │ 21 │ 22 │ 23 │ 24 │ 25 │ 26 │ 27 │ 28 │ 29

Derek collapsed back onto the bed, next to a sweaty Stiles. The both of them panted from their latest romp, Stiles waiting for the sensation in his legs to return after Derek totally drilled into him.

Th alpha werewolf’s libido seemed to be in overdrive, given the proximity of the full moon. Stiles was overjoyed about this fact, eagerly bending over to help his boyfriend release some of his sexual tension. That being said, after being the one to bottom over and over, Stiles was interested in a little change of pace.

“Hey, Der?” he panted, struggling to catch his breath.

“Hmm?” Derek hummed, already feeling himself grow hard at the scent of musk and pure sex permeating their bedroom. He gradually scooted closer to his boyfriend on the mattress, wrapping his large arms around his slender form, rutting his hardening cock against his perky butt.

“Wanna switch positions?” Stiles asked.

Derek paused his rutting and cocked his eyebrow at his boyfriend. “Huh?”

Stiles sat up and shifted himself closer to Derek. “Like, how about I be the top this time?” he suggested, trying to seductively wriggle his brow at the werewolf who only scoffed in response.

“Babe,” Derek snorted, “I’m the alpha, so I’m the top. There’s no way I’m gonna bottom… ever.” Sure Derek loved Stiles and he was well aware that he was in a homosexual relationship (clearly), but he couldn’t help but feel like bottoming was something that only the “girl” in the man x man relationship did. Being an alpha and being the tough guy that he was, Derek wouldn’t be caught dead being the bottom.

Stiles frowned. “A simple ‘No’ would’ve been fine…” he muttered before perking up. “Well, maybe you just need some convincing.” He snapped his fingers, grinning knowingly.

Before Derek could ask what was up, the alpha felt an odd tightness centering at his glutes. It felt as if he’d just finished a rigorous leg day at the gym, feeling his backside burn and ache as if he’d just completed some serious squats.

Derek’s lower back felt as if it were being lifted upwards off the bed, and the werewolf flipped over onto his stomach and looked over his broad shoulder, gasping loudly.

The toned butt that was perfectly proportional with the rest of Derek’s impressive muscles was magically bubbling out from his back. His butt grew in size, pushing out and rounding to form a fuckable bubblebutt that was too large for his body.

“Wh-what’s happening?!” Derek panicked, pressing both of his hands on his growing ass, paling as they felt small compared to his massive cheeks. He could feel his hands being pushed further away as his butt continued to grow in waves, thrusting itself away from his lower back, jiggling wildly with every movement.

Stiles couldn’t hide how turned on he was by watching Derek’s butt grow bigger. “Don’t worry, Der,” he said, loving how out of proportion his boyfriend’s butt looked, “if I did the spell right, it’ll wear off in a few hours.”

“Hours?” Derek repeated, flinching when the tightness finally subsided.

Bolting off the bed, the first thing Derek noticed was that his thighs had packed on a little more meat to account for the extra weight at his bottom. When he took an awkward step forward, Derek blushed as he felt his inflated cheeks bouncing and rolling over each other. He got to the floor length mirror in the bedroom, wincing as he looked at his warped reflection. The rest of his body remained unchanged, making Derek’s enlarged bubblebutt all the more ridiculous. It had to be at least three times its normal size, and it created a near perfect shelf as it jutted out from his lower back. Derek gave his hips a tentative shake, his heart racing as he watched his cheeks ripple and shake from the slightest movement. His butt was so large and out of place that his waist seemed to pinch inwards before ballooning out into his new bubble.

Derek looked away from the mirror for a split second to shoot a pleading look over at Stiles— Stiles was rock hard, and the second Derek’s eyes landed on his cock, he felt something inside of him flip.

Used to feeling a surge of lust and then having his cock rocket to life, Derek still felt himself get hard, but there was also an intense desire that he felt deep within his inflated butt. He didn’t know exactly what it was, but Derek felt desperately empty, and he couldn’t help but clench his enlarged cheeks with want.

His meaty pecs rising and falling as he breathed heavily, Derek couldn’t help but run towards the bed, ignoring the bouncing weight at his back. He threw himself onto the bed and perched up on all fours, shoving his inflated ass towards Stiles.

“Pl-please?” Derek begged, wiggling his hips teasingly and making his butt jiggle.

Stiles couldn’t help but smirk. “‘Please’ what?” he asked, crossing his arms over his chest.

The need was overwhelming, like there was deep, intense itch inside of him that needed satisfying. Derek gritted his teeth and pushed his giant butt closer to Stiles, grabbing his cheeks and pulling them apart to flash his tight hole. “Please fuck me!” he begged.

Stiles crawled forward and grabbed a hold of Derek’s waist, right at the crest of his overblown mounds. As he worked himself inside of Derek, he loved the way Derek tensed up.

“Oooohhhh fuuuuck,” Derek moaned as he pressed his forehead against the hard mattress as he was stuffed full. Automatically, Derek started to buck and roll his hips in tune to Stiles’s thrusts. 

As Derek was heatedly fucked, he couldn’t help but marvel at how intense the pleasure that surged throughout his altered body was. His cheeks bounced and rippled, adding to his orgasmic bliss. He could still see himself in the bedroom mirror, noting that he looked ridiculous with his large muscles and even larger ass, getting fucked silly by his much smaller boyfriend. His jaw was slack as he moaned like a slut, and his useless, untouched cock bobbed between his thighs, drooling precum.

Despite his previous disdain with bottoming, Derek felt himself craving the sensation of being filled with his boyfriend’s cock. His enormous ass wasn’t something to be embarrassed by, but it was a gateway to the ultimate pleasure.

By the time Stiles tensed up and came, filling Derek up with his load, Derek had already came about twice. He unconsciously flexed his cheeks as his boyfriend came, desperately milking him to get more of that sensation of being full.

“Holy fuck,” Derek panted, his chest slick with sweat. “We have to do that again!”

[2 Weeks Later]

True to Stiles’s word, the spell had worn off after a few hours, and Derek’s butt had deflated back to its normal size. Still, the werewolf loved to top his human boyfriend, and would mount him on the daily. However, there were now times when Derek would playfully walk up to his boyfriend and press his toned butt against him.

“I think it could use some more size, what do you think?” he’d coyly ask, biting down on his lower lip in anticipation as Stiles would snap his fingers, and Derek would feel his pants grow tighter…

31 Days of Derek Hale

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?”
