Their High School's gym class had all of their students mixed together. Unlike all the other classes it had 11-12th graders mixed in with 9-10th graders. So Jon and Zoe both knew their next class because they had Gym together.
Jon got to in front of the Locker room and saw his body by the entrance to the guy's locker room. His body looked at him and smiled then headed into the boys locker room. Jon was a bit surprised but figured it was better this way. He wasn't sure he had enough courage to actually approach his old body just yet.
Jon walked into the class room and was trying his best to not stare even though he could see Sarah and her friend's standing across the room with their shirts off. Jon saw a locker no one was using a notice it had the outfit Zoe wears for Gym. Jon go changed into the tight black shirt with the punisher logo on it and the tight black shorts that were made of some kind of spandex type material. they only actually came down an inch or two below Jon's butt and were skin tight. "Why does my sister have to dress so slutty?" he thought. He was glad at least to have a pair of sneakers appose to the boots he had on before. Jon headed out of the locker room thinking that wasn't such a bad experience.
Zoe ended the locker room and noticed Jon's gym locker right away because the shirt he wore fo gym was very bright orange like a traffic cone and could see it through the holes on the locker door. As she was getting changed she looked over and saw Steve and Biff talking in just their boxers. She started to stare and got an erection. Before she could really get to enjoy the erection she started to cum. Zoe had just had her first male orgasm because Jon's body still had very low stamina. "Whoa my brother is a real wimp if he cums these easy." she thought. Biff noticed that Jon had just cum while staring at him and gave Zoe a really mean look and said "Fag" Zoe finished getting changed and headed out. She thought "Well I'm sure I'll find that locker room orgasm to have some pretty entertaining consequences when me and Jon swap back."
Jon was standing in the gym waiting for class to start pretending to listen to Zoe's friends, and saw his body walk out over to Karen. As his body passed it gave Jon a wink. Jon thought "Well.. At least it looks like Zoe isn't going to mess my life up for now." unaware that she just came in the boys locker room while staring at Biff and worse Biff saw it happen.
As Zoe got to Karen she said "So Jon. Still wanna mess with your sister?" the way she asked it made it seem like it was Jon's idea to mess with Zoe, but it was actually Karen's.
Zoe looked over at Jon standing across the gym nodding and agreeing with her friends and thought for a second and said "Yes. I think I do."
