This just happened today and really turns me on just thinking about it.
A bit about myself. I'm a bit of an exhibitionist when it comes to the steam room and shower at the gym I go to. I wouldn't say I'm gay, maybe I'm bi, but I really enjoy jerking off with other guys. I've had a few experiences at the gym, usually just checking each other with a quick stroke in the back showers. Today was different than the norm though:
I had just finished some cardio and decided to hit the steam room before my shower. So I wear the compression shorts I was wearing under my shorts into the steam room. So I walk in and there are two guys in there. Immediately when I sit down one guy leaves me and this black dude wearing boxer briefs, probably in his mid/late 30s.
I've had some glances with him before, and wearing the compression shorts that show off my package got me pretty horned up really quickly. I'm above average, but not that big, at around 7' long and about 5' around, cut. So out of the corner of my eye I see this guy eyeing my semi through the spandex. So I lean forward to hide my poking bulge if someone came in, and I notice he starts rubbing his crotch. So I look over and not only was he rubbing through his shorts but he had actually whipped it out and was rubbing it. A little shorter than mine and on its way to getting hard was a smooth, uncut cock.
So I lean back to expose my hardon and to get a better view of him. He shows me his balls which were pretty big, and started openly stroking. So I whipped mine out too, showing him mine. However I was a bit hesitant because I was in view of the door, and people coming in from their workouts have to walk right by the door. So I have a few strokes and put it back in my spandex, straining to get out.
The guy puts his back and leaves the steam room and makes off to the showers. The way the place is set up is eight showers, five on one side, a handicapped one and two regulars on the other side of an aisle when you walk in from the side of the handicapped shower. Each has three walls; one on the wall side, one in the front, the back, and then the curtain on the side of the hall. So I followed suit, and noticed he headed to the last shower on the right. I took the last on the left, right across from him, and pulled my curtain a little, only so that people that walked in the room couldn't see, but he could. I took off my spandex and he took off his boxer briefs and we went right down to business. Here we were, right across from each other stroking our cocks and staring at each other's meat.
What I didn't expect was a glance to see if anyone else was taking a shower, and then he walked over to me and started stroking my cock and then grabbed my balls. I did the same and took his smooth uncut cock in my hand and felt the foreskin and stroked it a few times, then grabbed his big sagging balls, which almost got me off right away. But we heard a noise so he went back to his shower but we continued to stroke ourselves in view of each other. I put some foaming soap that was on the wall on my balls and starting pumping fast.
He looked like he was about to cum; he crouched down and made a face that almost made me shoot immediately. He pointed it at the floor and hit the floor with some shooting cum. As he was in his euphoria, I was stroking away, massaging my balls until I shot four ropes of cum on the wall in front of me.
As I tried to clean the cum off the wall with some soap and my foot, we both closed our curtains and finished our showers. When I go back Wednesday, I hope that he's there again, I'd love to have a continuation!
