I have enjoyed reading many of the stories here so I thought I would share one of my own.
There is a swimming pool at a nearby college that offers open swim time for local residents. One recent visit there something interesting and exciting happened.
I was doing my usual laps back and forth, taking a break after about ever other lap or so. Well I had found the intake water jets before, and had thought about trying to get off from them, but never really tried for fear of being noticed or worse, kicked out. But this day something was different. There were a very small number of people there for distraction. I relaxed near the jets letting the powerful stream wash across my cock. The feeling was wonderful. My cock tingled and sprang to life, creating a nice bulge in my Speedo.
I continued to swim laps, but found it more difficult as various sexual thoughts raced through my head. My breaks near the water jets became longer as I got more and more aroused. There I was with people around with a major hard on. The thought of my bulge being noticed got me even hornier. Before I even realized what was happening, I found myself at the point of no return. I could feel my balls tighten and my cock pulse as I shot several wads of cum into my Speedo.
I took a moment to recover and look around to see if I'd been caught, but apparently no one noticed. I swam a couple more laps and went to shower off.
Writing this story has me looking forward to my next day at the pool.
