Jon decided to wait until after school to torment Sarah any further. That would give her time to begin to think things were getting back to normal ... that perhaps whatever had happened to her earlier in the day had subsided.
However, simply because he wasn't messing with Sarah didn't mean that he was not messing with anyone else. Jon had tried his new device on all sorts of people at school. At lunch, for instance, Jon used the device to make Biff pull down his own pants in front of everyone in the cafeteria. In Chemistry, Jon made Mrs. Dearborne slap Steve Farber, and then he made Steve army crawl out of the room as though he was trying to escape Mrs. Dearborne without being seen or harmed further.
One person he had not see since before school started was Karyn, who, he assumed, was avoiding him.
Throughout the day, though, Jon had one goal in mind: humiliate Sarah. And it didn't take him long to formulate a plan. He just needed to wait until she was getting ready for cheerleading practice.
Jon rushed home as soon as classes let out. He wanted to make it back before Sarah got changed for cheerleading. When he got home, the first thing he did was make a few wishes on the stone.
"I wish that no matter what I'm doing in my bedroom this afternoon, no one will disturb me or think anything unusual is going on in here. I also wish that my TV grew to take up most of the wall it's sitting against and that it was currently tuned in to a channel that would show me what Sarah is up to."
Instantly Jon's TV grew and turned on to show him Sarah talking to some friends in the hallway, seemingly over the events of earlier in the day. If she wasn't, she certainly acted like she was very well. Sarah and a few other cheerleaders were heading to the locker rooms to prepare for practice.
Jon wished that he could fire the gun at someone through the TV and it would have the same effects as if he were right next to them. Then he fired it at Sarah through the TV after setting the device on setting number two, the physical sensation transmitter. Then, while watching the girls undress to change into their uniforms, Jon began to masturbate.
