The sensation made him stop what he was doing and pull his pants down, just in time to see his testicles crawl up into him, penis following closely. In their place a slit formed - a vagina, with blond hair. That weird sticky note had done this to him! But who was his counterpart? A scream from somewhere else in the house answered that question: Zoe. Before he could get up, she ran into his room, slamming the door behind her. "What the hell is this?!" She pulled her pants down to show a bulge in her panties that certainly wasn't there a minute ago. The panties went next and Jon saw his genitals hanging between her legs, though smaller. "I knew they were yours. How did this happen?" Oddly, she didn't seem angry, or at least not at him.
"I have no idea. I didn't think stuff like this could even happen." Then a thought occurred to him. He was so shocked at what he saw hanging between his sister's legs that he had momentarily forgotten. "That note."
"What note?"
Jon got down on the floor and found the pieces of the note he had torn up. He stood up and looked at his sister. "I found this yellow sticky note on my bedroom door. When I saw it, I read what was on it. Then this happened," he said, pointing to the vagina between his legs.
"How does reading a sticky note do something like that?" Zoe asked.
"I don't know." Which was the truth, since Jon had no memory of the wishing stone anymore.
