Karyn went into the other room and thought about what to wish for. Then she remember how Jon complained about gym class and mostly the locker room, how he was embarrassed to change in front of the other guys. She held the rock and said, "I wish that tomorrow when Jon changes clothes for gym class in the boy's locker room, under his normal clothes, he'll be wearing some lacy lingerie, and instead of being shocked or embarrassed, he will perform a sexy striptease for the boys, worthy of any professional burlesque performer. But once he has taken all his clothes off, he would suddenly snap out of it and realize what he'd just done."
There was a flash, and Karyn smiled. She then considered Jon's safety, and thought maybe some of the jocks would beat him up. She decided to make one more wish, "I also wish that none of the guys could physically harm him."
She smiled again, and went back into the other room.
