I stood there with my pants pooling around my ankles, and my t-shirt just barely reaching down to the top of my bald pee-slit. Karyn held the tiny prosthetic penis in her hand, looking at me. We stood there for an awkwardly long time.
"Well?" I asked, at last, "Can I have a proper penis now?"
Karyn smiled enigmatically and said, "Can I try something first?"
I started to get annoyed. "No," I said firmly, "I want a proper-sized cock and balls, please. I just want to get back to normal."
Karyn's smile faded slightly. "I thought you would be a bit more grateful," she said. "After all, remember who started this mess." She tugged gently on her hair for emphasis. "But okay, I'll help you get sorted out. Your balls are in that drawer over there," - she pointed at one side of the cabinet - "and I'll find you a dick over here."
I walked over and opened the drawer. It was lined with silk, and had rows and rows of indentations in the bottom. Each indentation held a rubbery-looking scrotum, in a bewildering variety of shapes and sizes. Some were so small that they would look tiny on a baby, and some looked like they could have been taken from a horse if their skin colour hadn't matched mine fairly closely. Some were very symmetrical while others were comically uneven. Why would I ever need this variety? I chose a set that looked almost symmetrical, and was about the same size as my old set. I turned around, and Karyn was standing behind me, smiling again.
"Give those here, and I'll put them on you," she said.
I handed my balls to Karyn and she gently reached down and popped them on my crotch. I instantly felt her hand cradling my nuts, and I looked down. It was the strangest sight - my balls looked completely natural, hanging between my legs as usual, but instead of a penis above them, there was still nothing more than a slit - slightly smaller than it had been before, but essentially the same.
Then, Karyn reached out and popped a penis on top of the slit. I instantly felt my dick again, and unconsciously breathed a sigh of relief. It had been nearly a whole day since I'd had a proper cock and balls attached to me, and it felt good to be back. Then I realized something was still wrong. Karyn's hand didn't feel right.
I looked down and my jaw dropped. Karyn had attached a huge monster of a cock onto me. It must have been at least a foot long, and it was flaccid. The tip dangled between my knees, and it was bigger around than my wrist.
"Karyn, what the hell!" I exclaimed.
"Well, you said that the other one was too small..." she said, grinning.
"Yeah, but you know it wasn't THIS big!" I said.
"Funny," Karyn replied, smirking, "I didn't think guys would complain about their dicks being too big."
"I'm not complaining," I said, hurriedly, "I just wasn't expecting... this!"
"Shall we see how big it can get?" she asked, and began stroking it gently with both hands.
"Oh my god," I said, as my massive member began to swell slowly.
Before I knew it, I was sitting on the couch, and Karyn was pulling my shirt off over my head. Fully erect, my cock was easily over two feet long, and the huge head was wobbling at my eye level while I sat. I needed both hands to reach around it, and Karyn could barely touch her fingers together as she stroked me up and down. Soon, she was taking her shirt off, too, revealing her creamy, medium-sized breasts topped with small pink nipples.
"If I put on bigger ones, I could give you a titty job," Karyn said, stroking her tits.
I wasn't sure how these magic prosthetics interacted with my body, but I think the sheer amount of blood needed to fill that huge penis was making me light-headed. I nodded, struggling to think of the right words. Karyn reached up, grabbed her boobs, and they detached from her body with a faint "pop!"
Then she held them out and touched them to my chest. With another faint "pop!", they attached themselves to me. What the hell?
I looked down and saw two boobs sticking out of my chest. I reached up and grabbed them - they felt like part of my body! I couldn't feel my own chest underneath! I tried to pull them off, but they wouldn't move - it just hurt if I pulled too hard. But it felt kind of good if I pulled a little more gently. I looked at Karyn.
She looked slightly odd herself. Her chest looked almost like a child's - she had tiny, pale nipples, but no breasts at all; just a very slight swelling where her pectoral muscles were. The rest of her looked womanly, but her chest was too narrow to look masculine yet too flat to look feminine.
"They look good on you," she said, pointing to the tits hanging off of my chest.
"Karyn, take them off!" I said.
"Not until we're done," Karyn said. She got up and walked over to one of the cabinets. She reached inside and pulled something out, attaching it to her chest. She repeated the motion and turned around. Now she had two impressively large breasts hanging off of her body. She walked over and wrapped her massive mammaries around my even-more-massive shaft.
I wanted to try to convince her to take my boobs off, but the sight of her breasts and the feeling of them around my cock were too much. I laid back and soaked in the sensation. Soon, I felt myself coming to another orgasm - but this time, nothing came out. I realized that my schlong was so long that the muscles pushing my semen out weren't strong enough to push it all the way out.
Karyn let me fondle her breasts while she fondled mine. My erection slowly softened, and my cock returned to its still-ridiculously-large size. Soon, my jizz started oozing out of it, and I had to get up to clean up the mess.
As I was cleaning up, Karyn went back and removed her huge jugs, replacing them with a more modest pair. I noticed that they were still a bit bigger than the ones she had put on me, but she put a bra and shirt back on so I couldn't compare directly.
"Karyn, are you going to take these things off of me now?" I asked.
"No, I like them," she replied.
"Karyn!" I demanded. "Take them off, NOW!"
"Ordering me around won't get you anywhere," Karyn said. I noticed she was holding the wishing stone in her hand now, too. I swallowed.
"I can't go out like this," I said, gesturing at my chest.
"No," Karyn agreed, "you need to wear some clothes before you go to school tomorrow." She smiled, then turned and walked out the door.
