Pre-covid I would sometimes use the gym in my office building when I couldn’t make it to my main gym. It was really small so pretty miserable if there was anyone else in there, with the tiniest locker room. Just two showers, one with a flimsy curtain and the other totally open, directly across from each other, sharing a drain. It was always a bit risky going up there because there were a lot of coworkers I didn’t want to see naked and didn’t want to see me naked lol
Anyway, I started seeing the same guy in there I’d never seen before. We kind of got on the same schedule. He was Latino, about 6 feet, completely thick everywhere. Huge legs, arms, chest, etc. looked to be in his late 40s or early 50s, wedding ring. He looked mean, actually, and didn’t like to share weights in the tiny gym, so I’d usually just steer clear of him and let him do his thing without any trouble.
Usually he’d be up there before me, so he’d finish first and would be done in the locker room before I needed it. But one time I finished first. I went to the locker room and was responding to emails so hadn’t started showering or anything, and 5 minutes after I finished he came into the locker room. Didn’t even acknowledge me even though the locker area was about the size of a walk-in closet, and just fully stripped down naked. I tried not to look, since he seemed very unfriendly and I didn’t want to get into a bad situation at my office, but interestingly enough he went straight to the shower without a curtain, rather than the one with one.
So, naturally, I took the one with the curtain across from him, which never really closed well anyway (you could get it to stay closed if you tried really hard and didn’t move around too much), which gave me the perfect chance to peek at him. He was spectacular- huge thighs, massive arms, big chest, and a thick, uncut dick hanging between his legs. His pubes were trimmed but not too short. He was just so manly, it made my dick stand at attention immediately.
I didn’t want to get caught, but it was a struggle to not watch him. And he kept angling his cock out at me, rather than facing the wall which is what I did the one time I had used the open shower in this place. He stood under the stream, shampooing with his eyes closed, his back arched so his cock was hanging out at me. I could have reached out and grabbed it if I wanted to risk getting fired (and sued).
He never looked straight at me, but I have to imagine he knew what he was doing, because in that position it started to grow. It didn’t get fully hard but it thickened a LOT, and started pointing even more at me. When he soaped it up, it felt like he was lingering on it, stroking it a little, and it got a little harder.
When the show had gone on long enough and I was horny enough I was thinking about risking it, he shut off the water, toweled off, and left. Never acknowledged me. Obviously after he left I quickly jerked myself off and came a LOT.
Shortly after that I discovered he worked down in the mail room. We stayed on the same gym schedule up until covid shut us down, and had several more shower moments after that first time
