Excited by the possibilities of his new wish, Jon hurried to school the next day. He really wanted to test his new powers out, but he also wanted to be somewhere where it would have the most effect. He had to go to school anyway, so he figured first period class would be the perfect place.
Jon fidgeted from excitement all throughout his class. Finally, halfway through the period, he decided the time was right. He discreetly lowered his hand from his desk to his lap, and with no sign that it was him doing it, snapped his fingers.
The room instantly exploded with noise as everyone orgasmed at once. However, Jon wasn't in any position to enjoy the mayhem as everyone's pants (and dignity) were trashed, as he was caught up in it, too. When he had made his wish to extend the orgasm snaps to everyone, he hadn't realized that included him, too.
Still, Jon got what he wanted: he knew the snaps worked, as the blushes and flying questions that filled the room showed. And if his experiment cost him a clean pair of underwear, it was worth it.
