Nothing seemed to change. He didn't have breasts or a pussy, and he wasn't wearing a dress. A quick search of his room showed that there weren't any mysterious high heeled shoes that he was suddenly expected to wear.
He did know, though, that he'd have to go sneak into Jon's place again and get more wishes to replace the stone. Unfortunately, he had been too clever by half. His prank was to make Jon's wishes inconvenient. So he did his best to limit Jon's ability to change that. For instance, Jon couldn't just wish for another stone, or wish for the ability to make wishes at long range, or say "I wish that anything I write down using an orange pen is treated as a wish". And these limits now affected Mike too--he couldn't break into Jon's place and do those things either.
It had taken a long time to plan things. He needed to figure a time when most of Jon's family would be gone, for one thing. It isn't every day that a whole family just happens to be gone, and it's even less often that the family is gone and Mike heard about it.
Two months later came Mike's chance. His father and Jon's mother had gone away to visit some distant relatives. He didn't know who else was going, but Jon wasn't mentioned, so there's a chance Jon wasn't going. Mike set his clock and woke up at midnight. Making his way across town to Jon's house, he looked around for signs of occupants. He noticed that his aunt's car wasn't there, but Jon's car was. So far, so good. When he quietly stepped up to the window, he could see Jon asleep in the darkness of the room. He could also see a crib with a sleeping baby in it.
"Heh," he thought. "It worked. Well, you can't hide a baby under a pillow like you can a wishing stone. It's always obvious where it is."
Mike crept around to the back door and slowly inserted his key to avoid making any noise. They hadn't changed the lock--but then, why would they? He's Jon's cousin and had the key for two years, and nobody knew that he once used it to sneak in in the middle of the night.
He made it down the hall and into Jon's room. Jon was snoring and the baby was just sleeping.
He picked up the baby. Startled by the hands roughly picking it up, the baby began to cry loudly. At the sound of his wishing baby crying, Jon was suddenly jolted awake, but meanwhile, Mike said "I wish I was at home with this baby."
Or, at least, that's what he tried to say. The words that came out were "I wish that I'll transform as Jon planned."
Mike suddenly felt very sleepy. He couldn't move or think straight, as if his brain wasn't completely developed, and he felt himself surrounded by water.
Jon slapped the light switch and saw a blonde teenage pregnant girl there, holding the baby, but disoriented and not able to move around very well. The baby slipped, slipped out of her arms past her bulging belly and fell onto the floor... bawling its throat out.
"Mikey, I think you should leave," said Jon. "I did warn you. By the way..." He picked up the baby. "I wish that this baby wasn't hurt by that fall."
"I'm not Mikey," she said. "I'm Mike."
"Uh-huh." He squinted. "My cousin? Really? Hmm. You do look like Mike."
"Yes, Jon. Don't you get it? I want what you have. And you won't give it to me. Now get rid of this spell!"
"You're in no position to complain," said Jon. "But it won't last that long. Not even an hour. I set it up to catch Mikey when he tried the same trick. Like I told him, it's like turning you into twins: one inside and one outside. Don't worry, unborn babies sleep a lot and don't remember much. It's not like the other you is in agony or anything. Now tell me what's going on."
"I'm not going to tell you. It started when I heard that Grandpa died and I realized you must have gotten his wishing stone. I..." Realizing what she was saying, Mike tried to cover her mouth with her hand and managed to cough and hesitate.
"Wishing stone? Like the pregnancy belly?"
"You fool. It was a stone. It only became a belly because I wished it that way. That's right, your precious baby who you have to save from being dropped by me is a magic rock. I turned it into a pregnancy belly, and then it went in you and came out like that." Mike snatched Jon's pillow and tried covering her own mouth. She only managed to make her words come out muffled and gave up, dropping the pillow. "I wished for my own magic rock, but it was stolen from an alternate dimension. Alternate-Grandpa took it back and cast a spell on me to make me explain things to you."
Mike regained control over her own mouth, finally. "I wasn't planning to tell you anything. I was supposed to be gone by now. But tell me, was the birth hard? And raising a baby? Must be harder than carrying a rock in your pocket."
"It's like the opposite of an afterschool special," said Jon. "A story where I can't ever learn how hard it is to raise a baby because any time something becomes inconvenient I just wish it away."
"To raise a fucking rock."
"Don't try to weird me out with that. Being a rock isn't any stranger than being a plastic belly. Now tell me how to get my dick back and remove these breasts." The baby was reaching for Jon's left breast and he had to raise it up. Feeding time again, and the baby had just woken up for a completely unrelated reason. "I see you're thirs-ty," he said to the baby, exaggerating his voice like parents do to babies.
"I tried to make sure you can't. If there's some way, I don't know how. Besides, I bet your baby will be disappointed at having to feed from a bottle. By the way, is it a boy or a girl?"
"It's a girl. Named Petra. You know, you're some kind of relative. First cousin once removed, or something."
"Petra? Magic stone... Now that's funny. Bwahahaha."
"I don't get it. But I need to figure out what to do with you."
"Eat shit and die."
"That sounds funny coming from a pregnant girl. I suppose I'll need to think of something before you change back. Let me see...."
