"I wish my breasts were a C-cup," Karyn said.
"Wishes can't be reversed, Karyn. Why did you wish that?" Jon asked.
"Well, ever since I made that wish after school, I got to thinking that maybe I could wish for a breast size that was smaller than what I have now, but one that would be larger than the size I used to have. That way, it wouldn't be contradicting my original wish. It would just be specifying it."
"That's actually a good idea, but you do realize your wish didn't come true. Don't you?"
"Oh yeah. You're right." She paused, as she began to feel strange. "What the ...? I'm changing, but my body shouldn't change this much. What's going on?!" she yelled, panicking.
A few seconds later, Karyn was a guy. And a very masculine one at that. "What happened?" Karyn asked, with her new deeper voice. "Here, Jon. Take the stone."
But just as Jon took hold of the stone, he felt himself beginning to change, as well.
