A few days ago I got the idea to go to a lake near my city and swim in it naked. The more I thought about the idea, the more I was tempted to jerk off in the lake. Because I like masturbation outside and adrenaline. So when I arrived at the lake I looked for a place where I wouldn't be seen. It was a warm day and there were many people at the lake. I quickly undressed and got into the water. First, I completely dove myself in the water to get used to its temperature, and after a while I was above the surface from the waist up. The whole time I was driving to the lake before I wanted to pee, so I started peeing and aiming at myself. I enjoyed it because piss play is one of my favorites. I even opened my mouth and aimed in it. When the stream of piss ended, I dove back into the water with only my head above the surface. I started jerking off and kept looking back to see if anyone could see me. It took about four minutes before I felt an orgasm approaching. I emerged from the water so that my penis remained under the water and when orgasm came I watched as cum came out of my penis and floated in the water. It was all so exciting, I really enjoyed it. When the orgasm was over, I sat back in the water and enjoyed the feeling for about 2 more minutes. Then I got out of the water on land and started to dry myself with the prepared towel. I then got dressed, not as quickly as I had undressed. I definitely have to do it again sometime.
