Jon checked out his new body. Everything was real, even the huge breasts. It was so weird having breasts.
But now it was time to change back. He said "Stop," thinking of the wish that made him look this way. But nothing happened.
He grabbed the stone. "I wish to know why I can't change back." The stone glowed and he got his answer. His eyes went wide. The wish to reverse the effects of a wish by saying "stop" and thinking of the wish was in contradiction to the wish he made right before that, the one stating that all effects of his wishes over the next forty-eight hours would end in forty-eight hours. He couldn't reverse the effects any sooner than forty-eight hours, so the "stop wish" wouldn't work.
Jon was stuck this way for the next two days.
