Jon thought for a minute. That bitch at school, Sarah. This could be fun. He thought about Sarah for a minute, and found himself in her house. She was apparently in the middle of getting dressed as Jon had his thoughts as he found himself in nothing but a bra and mini-skirt. An idea crossed his mind.
As quickly as he could, he took off all his clothes and ran a couple blocks from Sarah's house. He then thought about his own body again. POOF! He found Sarah had just sort of curled up on the floor, afraid once she found herself in Jon's body.
Jon hurredly got ready to travel the distance to see how Sarah dealt with this situation!
