I had just played a round of racket ball at my sports club and was covered in sweat. It was late, after ten at night and there were only a few guys in the locker room.

One of the guys I'd seen around before, I heard someone call him Dennis, once. Dennis is about 5'10' dark hair, smooth defined chest and a really hot butt. I have jerked off thinking about his butt a couple times already.

He had just worked out, and was stripping off his shorts. I sat on the bench across the room and pretended to look in my gym bag for something as I watched him pull down his jock strap, giving me a nice view of his beautiful ass! I got hard instantly! Good thing I was still wearing my shorts.

Dennis picked up a towel and headed in to the showers. His fat cock swung free as he walked past me. We made eye contact and nodded to each other, and I was suddenly afraid he caught me checking out his dick - which I was!

Once he was in the showers, I was alone in the locker room. He had left his gym clothes on the floor in front of his locker. That jock strap was sitting on top. I could see that is was wet with his crotch sweat. I rubbed my hard dick in my shorts and walked over his locker to take a closer look.

I was alone, with his jock strap right there. Impulsively, I picked it up and pressed it to my face. The musky scent of his balls was all over it. Closing my eyes I saw myself pressing my lips against his cock, welcoming it into my wet, hot mouth. I stood there in the locker room, sniffing his jock, my hand down my shorts, stoking my erect dick. It was good. I jerked and jerked, desperate to cum quickly and NOT get caught.

That jock was amazing! I sucked the fabric into my mouth and could taste Dennis' ball sweat. That made me cum. Biting hard into the damp jock cotton, I dumped my load of jizm in my shorts.

Sweating, spent, with a big wet cum stain on the front of my shorts, I took the jock strap out of my mouth and dropped it back on Dennis' pile of clothes.

When I turned around to go back to my locker, Dennis was standing there looking at me! He must have come back when I was all caught up and cumming. He looked me up and down, taking note of my still hard dick tenting our my cum soaked shorts, and gave me a confused look.

I didn't know what to do. So I just walked around him and went to my locker. I kept my head down the whole time as I got out of my soiled clothes and wrapped a towel around myself. Without looking up, I walked into the showers thinking I was totally busted.

After a few minutes, Dennis walked into the shower stall across from me, AND HE WAS WEARING THE JOCK STRAP!

He had seen me get off on the jock, and now he wanted to play in it, too! We got on in the shower that night, but that's a whole other story.
