I was invited to masturbate with a few of the members of our swim club.
I've always gone to swimming clubs where the men were naked. I always loved being naked with men and letting them see me.
In college I went regularly to a club, three afternoons a week, and saw the same men each time. One was particularly interesting to me, and I found myself moving around so that he would notice me. Looking back, it must have been a little funny, how I moved around the pool and the locker room!
One afternoon we were there, almost alone, just out of the showers, and we stood facing each other, drying off, and I began to get an erection. We were talking about something or other, and he had me follow him back to his locker to give me something. At his locker, he looked very blatantly at my erection, smiled, and said it was very 'lovely' and he enjoyed looking very much.
After that, we began arriving at about the same time, and would follow each other around, getting undressed, swimming, showering, dressing. Whenever we were private, our erections would grow, but nothing overt happened otherwise.
One afternoon, he told me that the pool manager had noticed us and wanted to invite us to come on a Wednesday evening to get to know us. I'd never gone in the evenings, and when I got there, I noticed several more men than usual, and that many of them had wandering eyes. I was really turned on to be swimming in front of so many eyes, and could barely supress a full-on boner.
When it was time to close, the manager came over and said that some of the guys were getting together in the equipment room, and did we care to join them. Yes!!
We walked in, and there were three guys there already, masturbating. Two of them were masturbating each other. The manager introduced me and told them that I was one of the bigger exhibitionists in the club! I was so embarrassed-I had no idea that anybody knew but my friend! Outed like that, I stood squarely in front of everyone and began stroking. All my life I'd wanted to jack off in front of my swimming buddies-it was the MOST exciting thing! After that, since they knew me now, I would sometimes masturbate for them in the showers or at their locker. Swimming had never been so much fun!
