Owen was panting as he stumbled over the line of the track field, having completed 3 laps. Sitting not to far away was the sports teacher, who had a less then happy look on his face. "I'm sorry Owen but with a speed like that I can't let you onto the track team." The sports teacher said, hoping up and coming to the panting Owen. Owen was incredibly skinny and boney, and this made sport a hell of a challenge. "Please sir, I promise I can do it…" Owen said, panting between words. He was clearly in no condition to be part of the track team. "Is there anything I can do? Anything that'll help me get on the team?" Owen asked once again, to which the sports teacher sighed and said "Listen, why don't you try and work on your thighs? Get them nice and big, that'll help you build up speed better." Owen gave a breathless smile and nodded.

At the lockers Owen stood by his friend Kane. "So apparently I have to get bigger thighs, which now just asks the question how do I get bigger thighs?" He mused, to which Kane listened, replying with "Well you could do a bunch of work outs, pushing yourself to your limit. Or you could use my easier solution." Owens eyes lit up hearing this, leaning into Kane and saying "Easier solution?" Kane chuckled to himself before saying "It's nothing magical, just a way to make your thighs bigger. Just come over to my place this afternoon." "Oh thanks man, that means a lot. How'd you even get something like that?" Owen asked. Kane let out another chuckle abd said "Oh you know me Owen, I always get the best deal."

It was later that day in Kanes bedroom, Owen having walked home with him. As the two placed they're bags on Kanes bed Owen asked "So where's the thing that'll help my thighs?" Kane turned and leaned under his bed, digging through the stuff before pulling out a tube of moisturiser that said "Body bulk up! : For women" "Huh? That's it?" Owen asked, he'd expected something more grand or cool. "Yep, just go into the bathroom and lather yourself up and you'll have thunder thighs in no time. Don't mind that it's for women, that was the only kind I could find." Kane said. Owen went to take it from his hands only for Kane to pull it back and say "Now, you gotta understand you'll owe me okay? You'll have to do something for me, no matter what it is." "Yeah yeah, I'll owe you." Owen replied, snatching the tube from Kane before rushing into Kane's bathroom.

Owen got naked before covering himself in the gel from the tube, head to toe. Every nook and cranny covered. As he finished applying the last of it he turned to the mirror, and realised how dumb he looked. He was standing there, naked expecting some magic gel to give him bigger thighs, and for what? To join the track team. Owen felt a deep blade of embarrassment pierce through him, for being so dumb. He was about to put on his gym uniform again when suddenly he felt his legs shift, as if they're hight was dropping, putting him down to 5'6. He wobbled a bit as his body hair fell off, making its way up from his toes, through his pubes and bum, up his bare chest, through his arms pits and across his face. By the time it was done the floor was covered in so much short hair you'd think they'd shaved a hamster. Owens eyes went wide as the hair he'd grown in puberty now lay on the floor, but it was far from done.

His head began to itch, the hairs beginning to grow. Owen began gang scratching his hair, but instead of falling out some of it got longer and longer till it was a nice bob cut. Then it began to turn black, confusing Owen even more. But that wasn't the only change happening, as his nose shrunk, his eyes became a soft hazel and his face became soft, that of a cute girl. Then his adams apple shrunk, causing him to cough, his voice becoming higher as he did. The change continued down his body, as his boney shoulders and arms slimmed out, the skeletal structure of his body now being more soft and thin. The same change went over the rest if his body, smoothing him out. All the while he just gawked at his now black hair.

But a change Owen couldn't notice was his dick suddenly getting hard. He panicked, not expected the random boner. But what made him panic more was when the boner began to shrink. It wasn't getting less hard, it was shrinking, getting smaller. Owen tried to grab onto it but as it shrunk it got slippery, making it hard to hold onto. And without even a chance to say goodbye, it was gone. In its place sat a vagina which Owen didn't know how exactly to use. But he didn't get much chance to try it as he grabbed at his chest, which began to burn and bubble. He held it like something was trying to crawl out, but even as he did he couldn't control the mass forming. Two nice molds formed under his nipples and grew, getting bigger and bigger till they sat on his chest, a perky pair of C cups that hung from his slender body. They added a nice curve to owens shape, although he was simply flabbergasted at where they could have come from. The change was almost over, as the final part, the one he'd wanted began.

His thighs began to grow, as if a pump was being used on them. As they grew, his ass grew to match. They got bigger, and bigger, and bigger, and bigger. His thigh gap ceased to be as his ass became a solid cake, a tight one which Owen was sure would catch every straight guys eye. And then it was done, over. Owen stood there panting for a bit, trying to adjust to his new body. Then once he did he wondered how it had happened, and it clicked. Kane, that sneaky rat had set this up! Owen was filled with as much rage as his body could allow, which considering his new ass size, was a lot. So he slipped back on his gym uniform, now seemingly a girls uniform and marched to Kane's room.

"What's the big idea giving me tits jerk!" Owen said, as she marched into Kane's room. Kane was sitting on his bed, smug as can be and said "That's a no way to say thanks Owen, or would you prefer Olivia?" "Very funny. I asked to have bigger thighs, not to become a girl!" Owen yelled, internally debating weather Olivia was a good name or not. Kane stood up and made his way to her, now easily taller then her. "I gave you want you want, so don't be so rude!" He spoke, in a more dominating tone to his typical voice. Olivia wanted to yell at him, but found herself too shy too. Even speak up. Kane grinned, seems it had not only made Owen a girl but a submissive one at that. He went back into his lade back tones saying "Well it's fair, but now your a girl with big thighs I'm sure you'll be great at running." Olivia considered this, before saying "I guess, thanks Kane." "No problem, but remember you owe me that favour?" Kane retorted, a wicked grin going across his face. Olivia sighed, saying "Yeah… What would you like me to do?" To which Kane replied "First lie front side on my bed, facing the wall."

Olivia was lying on the bed, as she could feel her new bust pressed against the bed and her now much larger ass protruding out. Kane smiled, and grabbed one of her thighs. This caused her to let out a little yelp, and she looked up at Kane ready to go off at him. Then she saw the look on his face, this was just part of the favour most likely. Kane massaged ger thigh as Olivia tried to control her breathing, it felt good. A weird kind of good. Kane then grabbed her other thigh, this time not eliciting a yelp. He massaged them, his hands so near her new pleasure zone Olivia found it hard to stay modest. Still she thought this was just it, that's until she felt him slap her ass! She let out a yelp and looked back at his grin, he planned this. And now, she didn't have the will to say no. Kane gently groped her bum as Olivia moaned into the pillow to hide it from him, but whole she wasn't paying attention she felt him pull down her shorts and panties. Her bum so bare she turned a bit and asked "Can… Can we just keep it… Keep it in the butt?" Kane smiled and said "Don't worry, I won't go near the special zone, just this area is good enough for me." He then climbed onto the bed.

As Kane undid his pants Olivia looked back at the sheer girth of his dick, even with lube would that fit. She began to feel anxious, worried that she might not be ae to take it. Then she fit a prodding around her asshole, an area she'd never really thought about in that way. She wasn't even sure she had feeling in it, then she felt him push his dick against it. It wouldn't go in, it couldn't. And yet, she felt the head of his dick enter into her ass. It was so big, it surprised her. He then pushed it deeper into her velvety ass as she let out a soft moan, gripping onto the bed. He pushed deeper and deeper till she felt it, his balls touching the rim of her ass. Then he began to pull out, before pushing in again. And in and out, again and again. Soon they were in a rhythm, Olivia's body shaking as he pounded her ass, moving to the rhythm of a drum only they could hear. And the beat got faster, the thrusts faster, the bed shakier till it happened, a load was burst into Olivia's ass. As Kane pulled out the two painted, not exactly sure what to say next.

Olivia crossed the line of the track field, not even breaking a sweat. The gym teacher came running up to her and said "Wow, I dunno how you did it but you seem to have gotten a lot better at running overnight Olivia." "Thanks sir, so can I join the track team?" Olivia said, a grin on her face for being praised for running. "Course, heck you might become the star runner!" The gym teacher laughed, smiling and patting Olivia on the back. She was about to thank him for the words when Olivia noticed Kane in the distance, standing in the yard. "Excuse me for a sec sir." She said, before jogging over to Kane.

"So what's it like, adjusting to being a girl?" Kane asked as Olivia came up to him. "Oh it's nice, kinda. Guys stare at me more, I think the girls dislike me, and I'm still not use to being called Olivia. Also how cone your the only one who remembers I was a guy? Not even my parents remember." She said, flicking out her fingers as she listed the changes. Kane chuckled and thought for a second before saying "Honestly, I dunno. Magic?" "Yeah probably." Olivia replied. There was tension in the air between the two, which Kane finally broke saying "So how do you feel about what we did last night?" To which Olivia hesitantly replied "It was nice, better then expected…" "Would you like to do it again tonight? My parents will be out." Kane offered. Olivia took a bit to think about it, before saying "Sure… This time we can explore my special zone~." Kane chuckled and replied "I'm looking forward to that, but you should get back to the gym teacher. Looks like your the talk of the team." He then pointed at the track team which had formed around the gym teacher, some of which were staring at Olivia. "Oh right, see you tonight Kane!" Olivia said, running back to the team. "See you too!" Kane replied, before muttering "I always get the best deals" under his breath.
