I decided to skip taking a shower. There was something seriously wrong here. An eighteen year old boy's nuts couldn't just vanish from jerking off, could they?
I pulled on some underwear. It felt weird, without any balls to press against the fabric. My ballsack just kind of squished against my leg, feeling sticky and uncomfortable. I knew that this was something to do with the stone. Where could I go for help? The only other person who knew about the stone was Karyn... I had to go talk to her!
I pulled on some jeans and a t-shirt and raced out the door. I went past Zoe, who was sitting in the kitchen, on my way. She gave me a dirty look, and I felt a hot flush across my cheeks as my face went red. A strange tingling went across my skin again, but I paid no attention.
I raced to Karyn's house as fast as I could go. My empty ballsack kept sticking to the inside of my thigh, and I had to keep stopping to adjust myself. Without any testicles to weigh it down, apparently, it just flopped around uselessly in my boxers and got stuck to things. I finally reached Karyn's house, and knocked on the door, out of breath. Karyn answered, and looked surprised when she saw me.
"What's wrong, Jon? You look like you've seen a ghost!" she said.
I was too out of breath from running to explain, so I went inside. Karyn took me up to her room, and I showed her the letter that was in the stone's box.
"Oh my God," she said, "Who did this? What do they want?"
"I don't know," I replied, "but I'm worried, Karyn."
"Has anything... umm... started to change yet?" she said.
I was at a loss for words. It was embarrassing enough that my sister had caught me masturbating - I really didn't want to talk to Karyn about it. Suddenly I was having second thoughts about telling Karyn anything at all. What was I going to do, show her my empty scrotum?
"Jon?" Karyn asked again, "Why are you so quiet?"
"I..." I stammered, not sure what to say.
"Something's changed already, hasn't it?" she asked gently, putting a hand on my knee. I involuntarily moved my legs together.
"Ummm, yeah..." I said.
"Is it something... embarrassing?" she asked.
My face felt hot. I couldn't even speak, I was so embarrassed.
"What kind of change was it, Jon?" she asked gently. I still couldn't reply.
"It's okay, Jon, you can tell me," she said. "Remember, I accidentally gave myself big boobs and blonde hair with the stone. Something someone else is doing to you can't be any worse than that!"
I smiled slightly, but still couldn't bring myself to say anything.
"Can you... point... to where the changes are?" she asked. I didn't want to, but my eyes involuntarily flicked towards my groin.
"Oh no!" she said, "Did something happen to your penis?!?" Her expression was horrified.
I finally found my voice. "Not... exactly." I whispered.
"Show me" Karyn ordered.
My hands started shaking uncontrollably. Half of me wanted to run out of the room, crying, and the other half wanted to show Karyn, my best friend, what had happened to me. I couldn't do it.
Karyn slowly and gently pushed me down until I was lying on the bed. Then she undid my pants and slowly pulled them down, and then pulled off my boxer shorts. I heard her gasp.
"What happened to your hair?" she said.
I sat up. My hair? I looked down at my crotch. When I got dressed, I had my normal tangle of pubic hair around my cock and balls, but now my groin was completely bald. The "treasure trail" that usually extended up my belly was gone, too. I couldn't see any hair down there at all!
"What...?" I said, "It wasn't my hair before, it was my..."
"Your balls!" Karyn exclaimed, noticing my flat, empty scrotum. "Where are they?"
I felt my face flush with embarrassment again. "I... I don't..." I said, and then stopped in horror.
As I sat there, with my pants and boxers around my feet, and my best friend staring at my empty scrotum, I could feel blood rushing into my penis. It started to stiffen and grow.
Karyn stood up and stepped away from me, her cheeks turning red. "Jon, is this turning you on?"
I felt another flush of shame and embarrassment as I realized that it was. I was incredibly aroused by my own shame and humiliation. I reached down to cover up my growing erection, when to my horror, my right hand grasped my shaft of its own volition and started stroking up and down, up and down.
"Jon, stop it!" Karyn said, stepping further away from me.
"I... I can't help it!" I said, trying desperately to stop my hand. I tried to pull my pants up with the other hand, but it just clenched and twitched uselessly.
I stood up. My right hand kept pounding away on my cock. I could move my left arm around, but my hand was useless. I tried to turn away from Karyn, and she simply stood with her back against the wall, her face bright red, and her mouth open in a shocked "O" shape, speechless.
Within a minute, I felt my climax coming. It came just as hard as it had this morning, and again nothing came out. The cramping in my groin followed immediately after. The white-hot pain was so intense that my knees buckled and I fell on the bed. It was all I could do to keep my groans of pain down to a reasonable level. After another minute, the pain faded away and my dick started softening again. I reached down and felt myself. My scrotum was completely gone... all that was left was smooth, tight skin between the base of my cock and my butthole!
"Jon, are you alright?" Karyn gasped, rushing over to me. "I saw the whole thing! Your... your scrotum just tightened up and shrank into your body!
