I (18M at the time) used to take swimming classes at a “national” swimming arena where many swimmers of all ages train. The adult locker rooms were MASSIVE (probably to cater for competitions an events) and had at least 30 cubicles in there. So, of course naughty things would happen there.

One time, I remember a swim class was so tough that I just had to take a breather in the cubicles so my coach won’t come and drag me out. Classes were ongoing so the locker room was relatively quiet. As i sat quietly on the corner of the cubicle, i heard two guys walking in laughing loud as hell,joking about something before entering a cubicle just two stalls away from mine. I knew they had entered the same cubicle because they were dissing each other about their abs and their penises.

A minute or two later, i assume they’ve whipped out their dicks to compare as they seemingly got more excited and joked even louder. All of a sudden, it got silent and i hear a familiar sound of foreskin being pulled up and down. One of them then went “ive never done this before”. These two guys were jerking each other off two cubicles away from me!

Besides the jerking, I couldn’t hear anything else so I stayed another 2-3 mins before making a loud noise when I walked out, just to mess with them.

Another time, i remember finishing up a private class before walking to the locker room. From a distance, I saw a guy and two girls laughing before “sneaking” into the men’s locker room. The girls were both brunettes wearing tight ass one pieces. Of course, i followed right behind them right to the end of the locker room, trying to be as discrete as possible.

Hearing hushed whispers and laughter, i knew these three has begun touching each other hearing their wet suits against their skin. Then, the guy got his trunks pulled down and the girls definitely started sucking his dick because the dude made weird gasping noises.

Unfortunately someone else came into the room and I had to act normal and leave. I certainly went home both times and masturbated thinking about the events lol
