Going to school was an easy problem to solve. "I wish that nobody at school would mind that me or Karyn are late."
"That's fine," said Karyn, "but what are you going to do about this? I'm your hand! I'm stuck on the end of your arm!"
"I have an idea," said Jonnie in her new female voice.
"You have an idea? You pretty much raped me."
"It's the stone, my feelings were all mixed up by it. I mean if I had a regular hand I wouldn't have stopped, so it was hard to stop when it's you. And you know you were aroused and you wanted to do it. It's not like I said 'let's make Karyn aroused,' it just happened."
"Well, whatever. What are you going to do about this? I can't go to school as your hand."
"I told you I have an idea. Have you ever watched any cheap horror movies where the guy has detachable hands he can control? I can just wish you're a hand I can detach from my body."
"Leaving you with a stump?"
"No, I can also wish for three hands. Left, right, and you. With you detached. It'd be like normal. In fact, I wish that me and Karyn were like that."
Instantly, Jonnie had another hand attached to her arm at the point where Karyn connected to it, and the connecting point to Karyn separated, leaving herself and Karyn as normal people.
Only... Karyn was still Jonnie's hand, although a third, detached, hand, and Jonnie could still control Karyn as naturally as she could move her left and right hands.
"We've got to get our clothes on... Wait a minute!" said Karyn, as she realized she was putting on her clothes without even thinking about it! Jonnie must have been making her do it. Then Jonnie stood up and zippered her pants, using her third "hand"--Karyn found herself pulling up Jonnie's zipper without even thinking about it.
"I wish we were in class," said Jon, after they dressed, and they appeared in their seats. Nobody even noticed they had been missing (or that there was anything strange about Jon being a girl.)
