Ty was having so much fun with his powers, he just couldn’t stand it! He had to change as many guys as possible as he wandered around the gym.
Luckily, it was during the middle of the afternoon, and several of his classmates from school wandered through the main entrance of the gym. They walked straight to the men’s’ locker room, so they could change.
Ty recognized these guys. They were all young freshmen who had just enrolled in his high school, so he knew who they were. Some were there to seriously bulk up. Others were there because they were curious and then again others were there just to see what it was like to join a gym.
“Welcome to Fitness Universe!” the young guy at the front desk said, as he greeted the small group. He gave the teens guest passes and he showed them where the locker room was. Ty decided to have fun with them as they all strolled into the large area where the showers were, along with the toilets, sinks, mirrors, and finally, long rows upon rows of metal lockers separated with wooden benches for the guys to sit on so they could easily change clothes.
Aaron and Brandon always hung out together, so they picked out two lockers in the back corner. They set their bags down and they opened their lockers. As they pulled out their gym shorts, they started to remove their shoes and jeans. Just then, Ty casually strolled in and opened his locker, which was just on the opposite side from theirs.
Both Brandon and Aaron were age 14. Ty was pretty cool with both guys, but he decided to have some fun with them anyway. They could use some bigger cocks and balls. And, which teenage boy didn’t want to have bigger muscles, right?
Brandon had just removed his sneakers and his jeans when he felt a tingling in his crotch. His 5-inch cock began to stir, as if some mysterious force was making his cock grow longer while his balls were swelling into large, apple-sized testicles.
“What the hell?” he gasped, as he pulled his underwear down, revealing his growing shaft. “My cock just grew by four inches!”
Aaron then pulled his shoes off and removed his jeans when the same thing happened to him! His 4-inch cock began to stretch out, and his balls began to swell up like crazy, inflating into large testicles.
“Dude! Something made our balls grow…. Uhh…” Aaron quipped.
As soon as either boy touched his enlarged penis, they both became hard as they had orgasms right there, covering one another with their cum, in the locker room! Ty acted as if he didn’t see anything, but, of course he knew what was going on the whole time!
They grabbed their towels and wiped off the cum everywhere before they put on their workout shorts and sneakers. Then, they quickly filled their water bottles and strolled out to the weight room to begin their work-out.
Ty just giggled as he decided to follow them. After all, it was a great day to turn two skinny teenage boys into two of the biggest, hulking muscle teens in the entire school!
