Having been circumcised when I was young, I've always been fascinated by uncut cocks. They catch my eye anytime I see one in the showers or getting changed, even in porn, and I can't help but stare and fantasise about playing with it.

One night when we were in our early 20s, my friend Mike and I went for a late-night workout at our local gym. Turned out we were the only ones there so we were able to blast some music and have have a good workout until we'd tired ourselves out and decided it was time to leave.

I'd figured I would have a shower when I got home before crawling into bed, but when we got back to the change room, Mike quickly stripped down and headed to the communal shower area. I'm a curious guy and I'd never had a chance to check out Mike's equipment before so I thought I might as well join him.

He was soaping himself up as I walked in, gave me a nod as I walked by and I nodded back. I immediately noticed that he was uncircumcised. At that moment I wanted nothing more than to drop to my knees in front of him and worship his cock. But I couldn't. Mike didn't know I was gay. I didn't even know if I was gay or just had a fetish for foreskin. So I got busy washing myself under the shower across from him.

But I couldn't help myself. I had to see more of it. I was staring directly at him as he slid his foreskin back and forth over the head a few times, cleaning it. He saw me.

"You like that, don't you?" He said grinning at me.

I didn't say anything but gave him a look that was probably somewhere between "what the fuck are you talking about" and "please don't tell anybody".

Mike was still smiling at me. "It's ok. You're cut and I can tell you're curious about how this works" he said shaking his dick at me slightly. "You can touch it if you want".

I wanted nothing more in the world than to play with Mike's uncut cock. My brain was screaming at me "NO, JUST CLEAN OFF QUICK AND GO HOME. FORGET THIS EVER HAPPENED". But before I even had a chance to really think about it, I had walked over to him and was reaching my hand towards his groin.

I tentatively wrapped my hand around his penis. Slowly pulled back his foreskin and exposed the head. Slid the skin back and forth a few times watching his soft pink head disappear and then reappear. The greatest game of peek-a-boo in the world. I was in heaven.

Mike's cock grew hard in my hand as I kept stroking it. Precum started leaking from his tip as I continued to slide his foreskin up and down. I had no idea how long I'd been wanking him for but I knew I could do this for hours. Until I was interrupted.

"You're going to make me cum in a second if you keep doing that" Mike said to me softly.

I couldn't tell if he wanted me to make him cum or thought it was getting too gay for him. I looked up at Mike, then back at his hard dick. Paralysed by indecision I somehow assumed my best course of action was to retreat. I slid the skin back over his head one more time, my own way of saying goodbye I guess, then went back to my shower and quickly finished cleaning off without looking at Mike again.

I walked out of the shower area and was nearly finished getting dressed when Mike came in. I saw briefly saw his beautiful soft uncut cock dangling in front of my face before he pulled up his underwear. And then it was gone.

To this day I wonder whether he had finished himself off after I rushed out. How things might have been different if I'd made him cum. Or if I'd tried to go even further.

But I didn't. I stopped and walked away. And we never spoke about it again. And I never saw Mike naked again. But for one night, for a few moments, I got to play with my friend's foreskin.
