John had always loved gym class growing up. It was one of the only times he felt like he could do good in school. No tests, no homework, no unnecessary grades, just good ole sports. That's all he wanted to do was play sports and workout. He'd kept his body in pretty good shape too. The small school gym had helped him keep a pretty active body. Plus the students helped keep him motivated. He didn't want to be some out of shape gym teachers that yelled at the students to just do laps.
He watched as individual students shuffled into the gym. They went down into the locker room to get changed. John opened up his laptop and the Chronivac screen popped up. He still had a good 15 minutes before the class was supposed to get started. Looking through the app he wondered if he should change other things about his body. It's not like he was upset with what he had. But the thought of having so much more wouldn't leave his mind. 'I can't change too much...' he thought to himself. But the idea of changing his body was really getting to him.
Large imposing men who had worked their entire life to get the tight muscular bodies wouldn't leave his mind. If he had worked out as hard as them he could have easily gotten just as big. His large dick hardened again at the thought of being such a massive man. He couldn't help but paw at it, trying to keep it down. 'Calm...' John scolded himself. He hadn't even typed anything and the thought of changing was getting too much. He took a deep breath and started typing away.
'I've been working out as hard as a body builder since high school,' he typed. Part of him wondered if he should hit enter. The weight of the change starting to weigh on his mind. But his finger fell down, hitting the key. He braced himself as he felt his muscles start to enlarge. All at once his muscles grew larger. Each breath added more and more mass to his frame. The average frame he had kept since high school ballooning out with all kinds of muscle.
John's legs naturally spread further apart. He'd already been sitting with his legs pretty far apart not to squish his enlarged penis but now the added muscle now forced it even wider. His chest bulged out pushing the shirt he was wearing to the limit. He looked down and he could only see the top of the massive size. "Holy shit..." he cursed. Giving the room a quick look he hoped none of the students heard him. They all were sitting across on the bleachers.
Looking over his body he still couldn't believe it. He'd lost a lot of his flexibility but he could feel strength in his entire body. He flexed his arms feeling the sleeves of his shirt tighten against them. "Damn..." he grinned. There was no denying he was stronger. Just flexing those big, tight muscles he could tell a difference. He needed to test them out.
