Jon decided to try again. "I wish you would like having your bigger breasts," he said. And the stone glowed.
"You're wishing it again?" Karyn said, then stared.
Jon looked down at his chest. It was bare, because he just woke up a few minutes earlier. He watched as two size-A breasts formed. He touched them and smiled.
"Jon? Are you okay?"
"Sure, Karyn. I just love my breasts."
Now, Karyn was the one that was confused. What happened? she thought. Is the stone broken?
She took the stone from Jon and said "I wish to know what just happened." The stone glowed, and her wish was granted. But it wasn't granted to her.
