It took some time to build up the courage to write my story.
I was into masturbating since I was 13 years old. Last summer I discovered a way to do it in a swimming pool amongst lots of other people. They never knew what I was doing. I did it about 15 or 20 times.
Sometimes I would wear my one-piece. Other times a bikini. When I got horny enough, I would lay on my stomach on my air raft. I would lay still and just get rocked around by the waves.
I would put my hands under me and open my legs just enough so my fingers could reach between them without showing.
So I would masturbate like this in public, with nobody noticing. When I cum I tend to wriggle about, but floating in the rough water, it didn't look anything amiss.
I had some very intense orgasms like this. Next summer I will definitely do it some more. I might tell my best friend about it too, but haven't done so as yet.
