When Cody stepped through the large, steel doors of a gigantic structure, he smiled when he realized that he found himself standing inside of the massive training facility where the high school gymnastics team has its daily workouts. There were ropes, bars and rings hanging from the very high ceiling. There were rubber mats everywhere, and dozens of students were running, jumping, and tumbling all around him. He became giddy when he realized he was surrounded by young athletes and their coaches! He wondered who he could change using his remote over here?
Two teenage girls walked right past him. They were wearing pink leotards as they casually strolled by him. He listened in on their conversation.
“Wow, have you met any of the new boys on the team, yet?” one girl said. “One boy has huge muscles!”
“I noticed how all the boys have huge muscles these days, especially on their arms. We should ask the coach about that!” the other girl replied.
Cody followed them from a distance as they walked up to a lady who was in her mid-forties. She was obviously their coach.
“Coach Louise? Why do all the boys have such big muscles on their arms where girls don’t?”
“Well, girls,” the coach replied. “The men have big biceps and triceps because they need all that strength to support their weight when they hang from the still rings and the high bars! The girls, on the other hand, grow bigger muscles in their thighs from all the jumping and running from the vault and the floor exercises! It makes sense, right?”
“What if a girl gymnast were to become a boy? He would have big legs and big arms, right?” one girl responded.
“Umm… I suppose so!” Coach Louise said, as she thought about it. “Why would a girl want to become a boy?”
“So, he could show off all his huge muscles, especially if he were a gymnast!” both girls laughed.
“Now, now, girls, you know that girls just don’t magically change into boys overnight. You know that!” Louise said sternly. “Now, you two, get back to your training!”
Cody just couldn’t believe his good luck! He overheard the whole conversation, and it was like a dream come true! So, he waited for the two girls to walk away before Cody pulled out the remote. He fiddled with the settings, and he finally entered in the desired properties. Which were for the target to regress to a male of the age fifteen, with big muscles everywhere and a high level of athleticism. Basically, the target would result in a teenage bodybuilder and the change would happen over thirty minutes. Cody aimed the remote at Louise, the female gymnastics coach, and he pressed the red “Transform” button. A blue beam of light struck the coach in her back.
“Uhh… I’m not feeling well…” Louise mumbled as she turned around and walked away, strolling towards the locker room. Her head was pounding, and her stomach was suddenly feeling nauseous. He heart was racing, she was feeling warm and it almost seemed like she was about to come down with something all over her body. To make matters even worse, all her muscles were feeling very sore.
When she entered the locker room, she sat down on the bench. She was about to vomit. She became dizzy and disoriented. Her muscles were aching all over.
“Uhhhhhnnnngggg!” she moaned softly as it seemed like her body was shrinking in height while her muscles were growing at the same time. She felt as if everything around her had increased in size, however, she was feeling bloated and heavier at the same time. Her muscles were burning as her chest bulged, her arms inflated, and her abdominal muscles became more defined than they were before.
Her face changed as her long hair became shorter. She lost her wrinkles as her skin became nice and smooth, like that of a teen. Her face rearranged as her jaw became squarer. Her arms became thick and strong while her shoulders bulged on both sides. Thick traps and delts raised up across her chest as mighty lats supported her bigger chest. Her breasts shrunk but bulging pectorals replaced them.
Her quads were already thick but now they grew even thicker and wider as her calves inflated as well. Soon enough, she shrunk by a few inches while gaining over fifty pounds of raw muscle all over her body.
Finally, her vagina disappeared, and a large, thick ten-inch cock grew from her groin, along with a set of balls which replaced the vagina. This had effectively changed her from a female into a male!
He had now become Louis, a teenage gymnast with big muscle all over. The leotard barely fit him, so he ripped it off as he looked around for something else to wear when he suddenly saw his reflection in the mirror on the wall.
“What… What happened?” he moaned, as he quickly found a men’s leotard laying around. He quickly put it on and just in time, before the two girls walked in. “I’m a BOY!”
“Oh! Are you Louis, the new guy?” the girl asked him while the other girl admired his muscles.
“Boy gymnasts have such huge muscles! Wow! Can I rub your arms?”
“Umm… Yeah, but… Uhh…” Louis stuttered as both girls began to rub his huge biceps.
“Ohh, wow, you must be SO STRONG!” the first girl said.
“How long can you hold an iron cross?” the second girl asked him.
“Uhh… I don’t know… I’m not a b—” he tried to say.
“Hey, Louis! After practice, do you wanna hang out with us?”
“Yeah, Louis! We need a strong dude like you to protect us!”
“I… Uhh…”
Then the two girls quickly walked away, so they could change into the dressing rooms.
“You better go to the guys’ locker room, Louis, before the coach catches you!” one of the girls shouted.
“Oh, yeah…”
Louis then got up and wandered off. As he passed the mirror, he realized that he was now a teenage boy. All traces of his past life as a female coach were gone. He stepped outside and wandered around, as he headed to the male locker room, passing Cody as he strolled by.
“Wow, look at that muscle dude!” Cody grinned, admiring the young muscular gymnast who used to be the female coach.
