Suddenly, all the girls that didn't used to be guys turned into guys. The girls that did used to be guys didn't change because the wish to make them girls couldn't be reversed.
Andy, who used to be Amber, screamed. "What ... what happened?!" He walked over to Jon. "What did you do?!"
"Nothing. I'm not the one that wished it. Erika was," Jon said, pointing at the girl that had just made the wish.
Andy turned to scream at Erika, but stopped as a feeling washed over him that he wasn't expecting: lust. Erika was hot. Very hot. Andy, as well as many of the other "new" guys, started to get aroused by all the sexy girls walking around the room. He looked down and saw a bulge form in his pants and knew what it was. It was a very strange feeling, but it felt good. And it felt even better as he started to rub it.
Jon couldn't believe what was going on. The guys had become girls and the girls had become guys. Horny guys. Maybe it was time that Jon should fix the situation before it really got out of hand.
