Race Day (FtM)

“Well, thanks for your time, and good luck with the race!” Laura concluded, smiling broadly at the two cyclists. She didn’t really have much interest in the sport, but the local news station she worked as a reporter for needed someone at short notice to cover the cycling race nearby, and she was the only one available.
The two men smiled in return, and turned around to make their way to get ready for the race. As they walked away, Laura couldn’t help but stare at the impressive rear end vacuum-packed into the blue outfit of the English cyclist she’d been interviewing, Matt, as it bounced from side to side as he sauntered away. After a few seconds, she looked away and shook her head. She had a boyfriend now after all, she couldn’t keep looking at guys like this anymore.
The cameraman, Andy, snapped her out of her trance-like state by announcing, “Alright, so now we should head over to the track so we can get in position to cover the race.” Laura agreed, and the pair of them walked for roughly ten minutes to get to the press area by the side of the track, where several cyclists had already gathered and some other journalists were waiting with their cameras, looking rather unimpressed. As she waited for Andy to set up his camera again, one of the other reporters approached her and said, “Don’t bother rushing, apparently one of the racers has disappeared off somewhere. That Matthew bloke.” Laura was a little taken aback, but after talking to a few other journalists and event organisers, none of whom knew where he was, decided to take it upon herself to try and find him.
She left her microphone with Andy as he continued to set up the camera, and headed away from the crowds to the small car park which housed the trailers which the cyclists used as changing rooms. She found the one which had Matt’s name written on the door, and knocked. Not getting a response, she tried the handle, which was apparently unlocked as she managed to swing the door open. Scanning the room, Matt was nowhere to be seen. However, she did notice one odd thing. On the grey couch at the side of the room, the clothes which Matt had been wearing during the interview were spread and wrinkled and - oddest of all - were totally covered inside and out in a strange peach-coloured goop.
Puzzled, Laura stepped closer and crouched down to get a closer look at it. Those were definitely his clothes, and the distribution of the goop was vaguely human-shaped, with most of it seemingly pooled inside the skinsuit, and with clumps at the head and arm openings of the suit, as well as two long clumps roughly connecting the legs of the suit and his shoes. She murmured, “What the fuck...” to herself, and after a few seconds of deliberation gingerly poked her finger into the goo, surprised at the viscosity and stickiness of it. When she tried to retreat her hand away, her eyes widened as the goop stayed wrapped around her finger and formed a firm string between it and the pile. She tried to shake it off, but in response the goop shot up onto her hand, and started crawling up her arm. She shrieked to no avail, as the entire pool of goop around the suit slid underneath her clothes, feeling like a slightly warm slime.
Laura’s heart racing, the movement of the goop slowed a little as it reached the top of her arms, as she noticed something going on. With all of goop from the couch now on her body, the part that covered her hands had gained a skin-like texture and tightly pulled itself around them, so that it seemed as if the goop actually was her hands. However, they were different from her normal hands: bigger for one, and her fingers seemed thicker. A similar thing had happened to her forearms, going from slim and dainty to thick with veins slightly visible under her skin, and her upper arms as the goop flowed onto her torso. The goop pulled itself tightly around her biceps, with more of the substance moving into the area to build onto it like clay, leaving her with firm muscle once the goop settled. Laura wasn’t particularly... opposed to whatever what going on with her body, more just, well, confused.
The goop continued to slip under her dress onto her chest, and she felt her breasts become totally covered. She was forced to let out a groan as the goop firmly pushed them into her chest, flattening them completely and seemingly absorbing them into the goop. In their place, she found the goop piling itself onto her as with her biceps to grow her two pillowy pectorals, almost as big as what was there before, and with two surprisingly pointed nipples to adorn them - stretching the fabric of her dress, along with her shoulders which had also had some mass added to them.
The goop then moved in both directions across her body, with one part going down and swallowing up her abdomen, widening her midsection with goop being piled onto her waist, and firming up her stomach, leaving her with a faint trace of a six-pack, covered by a very light layer of fat. While this was happening however, the goop was also quickly heading up Laura’s neck, thickening it a little on its journey. She was about to let out a scream, before the goop slid up her face and dove into her mouth and nostrils, and completely covered her eyes. With it sliding down her throat, she found herself blinded and unable to breathe for several seconds as she felt the goop’s movement stop at the top of her head. Once her mouth was cleared and her vision was restored she gasped for air loudly, clumsily pawing at her face with her manly hands and looking around the room for a mirror.
As she jogged to the mirror, she could feel that her face was certainly shaped and textured differently, and her long blonde locks no longer fell over her chest. Reaching the mirror, she realised that her face was that of an entirely different person. First off, this was the face of a man, clearly. She had a wider and firmer jaw, and her long blonde hair had disappeared somewhere only to be replaced with a head of short brown hair. Her nose was wider and her nostrils more flared, and the tip of her nose had taken on a red tinge. However, one thing become quickly apparent to her - this was Matt’s face. She was turning into Matt.
This was further backed up as the goop descended to her hips, and coated her ass generously. Trying to look around to watch, she watched as it swelled up further and further, until the back of her already-strained dress was pushed out by the unmistakable bubble butt belonging to Matt which she had been staring at just a short while prior. Her mouth gaped at the sight of it, and her first reaction was to reach a meaty hand around and give it a squeeze - wow. If that was even possible, that felt better than she expected. As terrifying as this change was, that was one part she really appreciated.
In contrast, the next area the goop covered brought on the changes that Laura was the most scared about. She shivered as it covered her clitoris and moulded it underneath her dress with piles of the goop, shaping it like a clay vase thicker and longer, becoming more phallic and firm as it grew. While this was happening, her labia reshaped itself into a scrotum with two decently-sized testicles appearing within. By now, her dress was tented by what was very much a penis, which had reached an above-average - she guessed - length, and a hefty girth, definitely bigger than her boyfriend’s, at least. She tenderly gave it a couple of strokes through the fabric, and gasped at the fantastic sensation she felt from this new part of her body. However, she decided not to go all the way with it just yet.
The final stages of her changes started as the goop began to pile itself onto her slim thighs. Judging from what she’d seen of Matt earlier, these legs were going to be something to behold, and she was certainly not wrong. Her quads continued to swell up further and further, and as they finally settled to their new size, Laura’s eyes widened. She hadn’t had time to appreciate them when she first saw Matt, but now she realised that these were probably the biggest legs she’d ever seen on anyone - never mind herself! The goop continued onto her calves, expanding them to similar extents to her thighs and making her legs as a whole look more well-proportioned. Finally, the last dregs of the goop covered her feet, expanding them several sizes to what she’d expect for this new body.
Laura stared at herself - or rather, Matt’s self - up and down in the mirror and tried to get to grips with the situation. One thing that stood out was how poorly her dress, ripped in several places, fit her new body. Testing her strength, she managed to totally tear off the dress with her hands, triumphantly throwing it on the floor, and after managing to squeeze herself out of her underwear found herself naked in the mirror. She flexed a bicep in the mirror, and grinned to herself, laughing, “Maybe I could get used to this,” before covering her mouth. Woah. She was not expecting to sound like that. Her voice was deeper, naturally, and now had Matt’s charming accent.
After a couple more minutes of checking herself out in the mirror and giving herself a squeeze here and there, Laura realised that she’d probably have to turn up and pretend to be Matt so the organisers wouldn’t think that he’d gone missing. Scanning the room for something to wear, her eyes settled on Matt’s previous outfit that’d been covered in the goop, which was now miraculously clean, as if it had never even been there. She grabbed the shorts, stepping into them, and wriggled them up her legs until they were wrapped around her monster thighs as tightly as possible, managing to tuck her now-calmed cock into them. She pulled the shorts’ straps over her shoulders, before managing to pull the event jersey over her shoulders, zipping the front up and pulling the sleeves up until her biceps were snugly covered. She then strapped on the shoes and pulled on the gloves, before putting on the sunglasses and strapping in her helmet to prepare for the race. Laura checked herself out in the room’s mirror one last time, before heading off to the race.
Now, she wasn’t totally sure how she’d actually be able to do this race, considering she hadn’t been near a bike since she was a child. On the other hand, she also had vague recollections of participating in many cycling racing throughout her life. These conflicting memories confused her, unable to tell which was the truth, but as long as she could get through this race she’d be fine. As she walked across the car park towards the arena, she felt more and more confident about her ability to participate in the race successfully, remembering details about some of her competitors even. However, she did find even walking in this body a struggle, the size of her legs forcing her into more of a waddle, so she didn’t really know how she could expect to do well cycling. Also - how was her boyfriend going to react? She wasn’t sure she could even go back to him like this, and after all, didn’t she have a girlfriend back home in England? That didn’t sound right - did it?
A few minutes later, she had made her way to the starting line at the track, after being shouted at by a couple of the organisers for disappearing out of nowhere. She did retort back to them, something she’d never really done before, but otherwise didn’t make a fuss. She noticed the cameraman on his own, looking slightly worried - what was his name, Aaron? - but now she was focussed on trying to win this race. She was still nervous about it, of course, but she felt this newfound adrenaline and cockiness - had remembered how to actually cycle! The referee shot the starting gun, and Laura sped along the track with the other racers. Not that she was focusing on them, anyway, but she managed to overtake them one by one.
After a few minutes of intense physical activity, Laura crossed the finish line in a respectable second, which she was more than happy with! She smacked her firm chest with her hands, before spreading her arms apart, basking in the (albeit fairly small) crowd’s cheers. At that moment, she felt that this future life wouldn’t be so bad after all.
