When I was 19 I had a year pass to the pools, as I was a regular swimmer and it was a great way to end the day and was always nice to relax after a round of laps in the spa pool. The spa was located in the middle of the swimming area. I used to love this because it would be late at night when all the hot swimmer guys would be around and I could check them out.
One time when I decided to hit the spa pool and enjoy a soak. Usually I like to face away from the jets and enjoy a massage on my back and neck. This time when it got too hot I decided to hang over the edge and enjoy a look at the guys swimming in the lane pool. The idea turned me on and I started to get a little stiff, then I noticed the jet was starting to hit my groin in a way that got me so turned on. The way the jet was pushing against my shorts started to make my penis vibrate, and got me even more aroused.
Another thing that was turning me on was the fact the spa pool was crowded with a group of guys behind me. After half an hour of doing this I was beginning to edge on close, and the thought of having an orgasm right then and there started to make my heart race. As the feeling got bigger and bigger the thought of the hot swimmer guys, the jets and being noticed was so arousing that I had to cum.
A whole load of cum filled my pants and my back started to jolt in such an intense orgasm that I had to go underwater to try and be unobvious. When I got up it appeared no one had noticed my sin, and when my erection subsided I hit the showers. My cum had glued all to the hairs on my thighs. I repeated this a few times, all having intense orgasms, and is something I look forward to doing again.
