After Jon woke up, he looked at the stone and got an idea. "I wish Karyn was standing in my bedroom, completely naked!"
Instantly, Karyn was not only in Jon's room, naked, she was pushing Jon towards the door. "Get out! I told you I wanted to dress. What kind of a peeping tom are you?"
"But I just wished..."
"You wished what? I told you just because my shower's broken and I came over to use yours doesn't mean you can peep!"
Jon, frustrated, left the room. He realized that the stone had made up a reason for Karyn to be there naked... but even if Karyn had just teleported there, was it really smart to intrude on his naked friend like that? Karyn would hate him for it, he knew.
When Karyn was dressed, and Jon finally could enter the room, he tried to make up with her. After she had calmed down, they decided to talk over wishes with each other. Holding up the stone, Jon said "I wish I was an extremely masculine guy."
Jon, in a flash, grew several inches and developed muscles, but Karyn didn't seem happy. "Jon, what was that for?" she asked.
"I wanted to do that! I don't need to be scrawny any more."
"Jon, you also just wished that you could never be turned into anything other than a guy. And you're lucky you didn't turn into some freak 9 foot tall guy. Or die of a hormone imbalance."
Jon pressed the stone into Karyn's hand. "Here, you try it."
"Good grief. Jon, what do you expect me to do? Say 'I wish I was a very feminine girl, the kind that always wears makeup and only wears skirts and dresses, and I always had the newest fashions"?
Then she looked at the stone Jon was pressing into her hand and said "Oops."
"Well, looks like you'll never get turned into anything else either," said Jon. "You'll also never wear pants for the rest of your life!"
"Oh my god. You're right." Karyn sighed. "Girly clothes are nice, but women should be able to wear anything they want. Sigh. I really messed up. I'm never going to have pants on. Ever. I don't even think I can have bras... or even shoes. Hats. Jackets. Only skirts and dresses."
Karyn took the stone and said "I wish Jon was a girl."
Jon shimmered, but didn't change.
Karyn, panicking, realized what she had just done. "Jon, you take this back. I don't know exactly why I wished that... I'm glad that wish didn't work, because it contradicted the other wish. If it had worked..."
"... I could never be male again," said Jon, taking the stone. "At least that failed. I'm not a girl and I can still say things like 'I wish I had a larger set of balls'."
"What a stupid wish," said Karyn.
"Huh? That one wasn't..."
"Please don't tell me that you're so insecure that you actually need to enlarge your balls. It's not as if anyone's going to look at them and say 'oh, neat, he has big balls'. I mean, what's the point?"
"Yeah, I guess you're right." Jon tossed the stone over to Karyn.
Karyn fumbled at and caught it, but said "I don't want to make any more wishes."
"Aww... isn't there something you'd want to try just once, to know what it feels like?"
"I don't know. Hmm. I wish I was lactating. I can always wish it away if I dislike it. I wish I was 8 or 9 months pregnant. I wish I had a cute handsome boyfriend who loved me."
Jon gasped as the wishes took effect and Karyn's belly bulged. "Karyn, wishes aren't reversible. What makes you think you can reverse the lactation wish? Or the pregnancy wish?"
"Oh, I'm sure I'll think of a way."
"If I were you, I'd have thought of a way before making the wishes. And as for your boyfriend... I didn't know you were a rapist. If you use magic to make someone fall in love with you and you have sex one day... that's rape."
"I never thought of that!" said Karyn. "What should we do? We need to figure out some way to reverse all these stupid wishes, and learn to make better ones."
"Yeah," said Jon. "Just one more though.... I wish I was the most masculine person on the planet forever more."
Suddenly Jon felt very light. Things were cold. The sky outside his window was red, and the ground another shade of red. The horizon was at the wrong place, and Karyn was gone. He would soon find out that he had been teleported to Mars, a planet where there were no other boys or men to be more masculine, and he could never return....
