Jon headed into the locker room and got changed.
Once he was out and Gym started he caught himself staring at Sarah's butt as they were running laps. Jon started to get an erection and it was dangerous to run with a boner, so he stuck his hand in his pocket and said "I wish I didn't have an erection."
Jon's mom heard the wish and was a bit surprised by the wish and then thought that it must be hard for Jon in the middle of puberty, and then she got an idea to 'help' Jon "Grant the wish by making it so Jon hadn't started puberty yet." She thought that would make Jon less stressed and take care of his erection problems.
In gym Jon was running and then felt weird. He was getting smaller, and said "What the hell" and was shocked by his high pitched voice. Once Gym was over he headed into the bathroom part of the locker room and saw in the mirror himself, but he looked younger, but his face still looked a bit older then it did when he was a kid. Jon went into the bathroom stall and pulled down his pants to see a hairless tiny penis. "fuck" Jon said allowed. He thought about how this could happen and then thought "Maybe I haven't hit puberty yet?"
He went to his locker and saw his clothes were smaller and got changed.
Stepping out of the gym Jon saw Karen standing with the other girls in a top that showed off her new cleavage. It made Jon horny, but his body wasn't able to adjust to his mind's arousal. This feeling Jon was getting as his body wasn't have to get an erection was a million more times frustrating then getting a hard on.
