Back?

The month passed in a very boring way... Joan should have wished she'd be Karyn's vagina for a day, not a month. But eventually the month did end. She was suddenly Jon again, and she suddenly remembered being Jon. The idea of being a vagina held excitement for him again... now that he no longer thought he was a girl. And Jon still had the stone. Jon knew that his original wish, to return to the body of Jon Gibson with the stone in his possession, had taken effect. But what else had happened? Someone (his mother, unknown to him) had had the stone for a month, and they must have made some wishes. They probably didn't even remember what their wishes were any more... but the wishes still had taken effect. Jon stared at the stone. He could ask it what the wishes were. But did he really want to know?
