There was a flash of light and Jon could feel his clothing changing. After the light faded and Jon could see again he saw himself in the mirror wearing a gray skirt suit (his sister is in her mid-twenties and is a secretary for a law firm) he checked under his top and could see black bra straps and after lifting up his skirt he saw white panties.
Jon realized that he hadn't thought his whole wish through, this would be sexually exciting, but it would still be very weird. He would be wearing girl's clothes Jessica's, His older working sister, plus she went out clubbing often she usually dressed sexily for that. He decided since he couldn't reverse it he would just have to roll with it. Everyone else saw it as normal anyways.
