I tried to concentrate on my normal chest, but it was really hard with Karyn's lovely fun-bags hanging on display so close by. They slowly started to shrink, but Karyn kept asking me what was happening. I couldn't answer - what was I going to tell her? If she found out that I could see her naked, she would be furious. I concentrated as hard as I could on my normal chest, and my t-shirt slowly sank down as the breasts got smaller and smaller.
Finally she reached for the box that contained the stone. I tried to stop her, but she was too quick. She held up the stone and said "I wish I knew what Jon wished!" mere seconds before I knocked it out of her hands.
The stone flew into a bush and I dived after it, horrified at the thought of losing it. I banged my tit, which wasn't quite gone yet, on the edge of the wall as I slid off, and it hurt like hell. Not as bad as being hit in the balls, but almost as bad as hitting your funny bone. When I recovered the stone and turned around, Karyn was starting at me with a strange expression on her face.
My eyes involuntarily glanced down at her exposed pussy and tits. Her gaze followed mine, and suddenly her eyes widened as she realized that I could see her naked. Her arms flew to cover her breasts and her crotch.
"What the hell, Jon!" she yelled at me.
"I... I...." I stammered, unable to form words. Shit, I had really messed this up. I should never have wished to see Karyn naked. Or, at least, I should have worded it differently - maybe wished that Karyn would want to show me her naked body or something. But that felt wrong too.
"Give me the rock!" Karyn demanded. I held it close to myself.
"But..." I said.
"If you ever want to be friends with me again, you will give me the rock right this second," shouted Karyn.
My arm reached out, shaking, and dropped the stone into her hand.
"I wish that Jon couldn't see me naked," Karyn said. Nothing happened. Karyn moved her arms away from her body and I could see her tits and bush again. "Shit," she said, as my eyes kept flickering down to her nakedness. She obviously realized that her wish hadn't worked. "Fine, then I wish that I wasn't embarrassed by Jon seeing me naked," she added.
Suddenly Karyn's shoulders relaxed, and she laughed cheerfully. "You made some fucking dumb wished, you know that, Jon?"
I nodded. "Yeah," I said, "I just couldn't stop thinking about you last night. I'm sorry - it was wrong of me to wish that." I hung my head in shame.
"It's alright," said Karyn. "In fact, it's kind of flattering. I mean, you obviously can't stop thinking about my boobs." She pointed at my chest.
I looked down. My t-shirt was pulled tightly across my breasts again, as they had returned to full size while I was looking at Karyn.
"Shit!" I exclaimed. "I meant for that wish to work differently. My idea was that I would have to think hard about something to maintain a transformation, but it seems like it's harder to make the transformation go away."
Karyn smiled. "I think the problem is that you aren't really in control of what you concentrate on. If I told you to think about that green-skinned girl from the Star Trek movie..."
Her voice faded away. Then she said, "Holy shit, you're suggestible."
I looked at myself. My arms were green and hairless! And my hands were unmistakably feminine! A strand of long, curly red hair fell down into my field of view and I gasped.
"Oh no!" I said, in a voice that was undeniably female.
Karyn looked around. "We've got to get somewhere more private," she said. "People are going to wonder why I'm hanging out with a green-skinned alien."
I tried to concentrate on my normal body. The green on my arms faded, but I kept thinking about the sexy green-haired girl. I had stayed up late, daydreaming about her for days after I saw that movie, and it was really hard to get the image out of my head.
"I have an idea," said Karyn, raising the stone.
"I wish that I could control what body shape Jon is concentrating on by snapping my fingers and ordering Jon to concentrate on something specific. I wish that my orders would last for up to twenty-four hours, or until I tell him to stop."
"Now, Jon," she said, snapping her fingers, "I want you to concentrate on your normal body."
The image of the green-skinned girl faded from my mind like smoke. I was picturing my normal body, exactly the way it looked when I was looking at myself naked in the bathroom mirror. I looked at myself, suddenly panicked that I would be naked too, but I was still wearing my clothes. I looked perfectly normal.
"Thanks, Karyn," I sighed.
"Alright, let's go to my place," Karyn said. "My parents won't be home for a couple of hours. We can figure some of this stuff out there in private."
We walked to her house, and I couldn't stop thinking about my perfectly normal body. I barely even looked at Karyn's gorgeous, naked body beside me. Weird.
