Solution 2

"Karyn, this isn't funny."
"would stay a penis until he wanted to to change into something else." more laughing and giggling Zoe: not granted
"Jon, the stone didn't warm up. I'm not sure that last one worked."
"Shit! What do we do now. I'm shorter and still no closer to having my penis back. I don't want to think about what happens if I keep this too long, " said Jon pointing to his groin
"Gotcha. I have an idea. Mind if I make a wish?"
"Go for it, it's hard to make things worse."
"I wish that Jon would change to fit into whatever clothing he wears." Zoe: Granted, but when Jon removes the clothing he would go back to his normal body.
"Jon, the stone warmed up. I think it'll work."
"How does that help?"
"Time for phase 2. I wish that Jon had a wide variety of male clothing in his bedroom." Zoe: Granted, but the stuff that is still there stays.
"There, that should do it."
"Thanks Karyn, your a lifesaver. I'm going to head home to test the wish."
"Good luck, I'm going to check out what I did too. Here's your stone."
Jon walked home, taking shorter steps than usual. It took a couple extra minutes. He'd have to figure out how to get his 16 year old legs back. He stopped by the kitchen and got a cereal bar, which took a bit more reaching than normal. While eating the bar, he made his way to his room.
The room looked about the same, but the dresser had an extra shelf. He opened it and saw some pants, cargo shorts and boxers, all his prior size. He also saw some work out outfits, cuff links a speedo, a trunks bathing suit and one massive sweatshirt. Excited, he put on the only pair of boxers and his old penis came back. Then shorts and immediately his legs bulked up. He pulled open the top and looked town. A smile came to his lips and he grabbed it. It never felt so good to have his little Jon back. He let go and got out his phone.
"It worked," he texted
A moment later Karyn texted back "Mine worked too. Problems solved. What do you want to do today?"
"The same thing we do every night Pinky, try to take over the world."
Karyn came by to pick up Jon, since she could drive. They made their way to the mall. They spend the afternoon looking at videogames, DVDs and talking about movies about wishing. Karyn had to got one or two things at the clothing store, "just in case," whatever that meant When they were in the car, the started talking about what else to wish for. They picked up some chinese food and went to the treehouse again. Jon talked about getting together again, but Karyn said her new fit family was going for a day long hike tomorrow, but maybe they could hang out that evening. Jon walked home thinking about the next day. He said hi to his mom and dad who were watching "Ladybugs" Mikey was in his room, getting ready for bed. Jon went to his room and booted up his computer.
"Hey Jon, " said Zoe from his doorway.
"Hey Zoe, what's up?" asked Jon, who was a bit taken by surprise. Zoe didn't come to his room often.
"Just checking on you. I know Grandpa's passing is tough on you."
"It is Zoe. Thanks for asking."
"Want to talk about anything?" Zoe asked as she glanced at Jon's open closet.
Jon briefly thought about telling Zoe about the stone, but decided against it.
"Na, I'll reach out, but I really appreciate you coming. I really do."
"My pleasure." Jon thought he saw a bit of a smirk as Zoe turned around.
Jon went back to catching up on some news on BBC, checked out scores from the day's games, played some minecraft and then wandered his room. He briefly thought about doing homework, but it was Saturday. He looked at the time, and saw he had some time before bed. He closed his door and went back to his computer. He took off his shorts and went to his favorite porn sites. With the sound off, he started to do what 16 year olds do when they are alone looking at porn. A short 3 minutes later, he cleaned up and went to his drawer to get out another pair of boxers for bed. When he got up this time, he saw his closet. There were some dresses and skirts, mixed in with his girl pants and apparently a tuxedo. How did those skirts get there?
A problem for tomorrow. Jon put on his shorts and went down the hall to the bathroom with his towel. He went into the bathroom and closed the door, locking in. He took off his shirt and started to flex a bit in mirror. He thought that if he changes to fit into his clothing, maybe he could wish for a buff guy's workout shirt. Thinking about what else he could wish for to enhance his body, he pulled off the boxers. The moment the waistband was past his penis, it rapidly shrunk back into a vagina. His legs also went back to 12 year old legs. His eyes went wide. He pulled the boxers up, and everything went back to the way he wanted it. Up, down, Up down, up down. The results were always the same
"Fuck!" thought Jon, taking the boxers all the way off, allowing his legs to become his now default legs. He got into the shower, and washed off. He couldn't bring himself to clean his vagina. If he didn't touch it, it didn't exist. After he dried off he put on his boxers before flossing/brushing his teeth. He went back to his room and put his towel behind his door. He went to the bed and texted Karyn
"I'm me, but only when I am wearing my clothing. If I take off the clothing, I go back to what I was before."
He put down the phone and rubbed his lower abdomen. It was in knots from his nerves. He heard the familiar sound of his friend texting him back
"We can work on that. Let's think about it. Don't do anything rash tonight."
