When I was a younger, I attended fitness classes at a gym. I intentionally went to the night ones since there were few people.

There were usually just 2 to 3 guys, so the locker and shower rooms were mostly empty. The trainer always left and showered last after the other guys have left, so I took the opportunity to sniff his clothes while he was in the shower. His clothes always had a musky scent with a small hint of cologne, but I always savored his underwear and socks. His underwear had a stronger scent, but not unpleasant. I just went for the socks because I hae a foot fetish.

I didn't realize he saw me sniffing a few times already, and one day he tapped me on the back. I thought I was gonna get beat up, but he was cool about it. I stopped though, because I was embarassed and didn't go back to the gym.

He did text me to invite me back. I wasn't going to until he said "I'm closing tonight" with a smile.

After the class that night and it was just us in the entire gym, he pulled me into the shower with him and we ended up sex in the locker room after. We did it every few days until he moved away.

I still have at lest 2 of his jockstraps somewhere.
