By a Lake

Once earlier that year I told to my best friend I was masturbating for some time. It seemed he wasn't really interested in the topic, maybe even a little surprised by it, so I let this debate be, as I didn't want to offend him. Few months later during the summer holidays my parents agreed he would come to visit me in our weekend cottage, so his parents drove him to stay one week or ten days. I was supposed to show him the place around so we sat on my and my father's bike and went for a ride. I thought he wouldn't have energy to go far, as he just arrived, but obviously he was glad to be out, so we went a little bit further, finally reaching the lake, where I went daily with my friends from the village. We saw some people swimming there on the main part of the shore and it was perfect time for refresh, but we didn't bring any bath suits, so we couldn't join those people. There was a small secluded bay, where we usually went if we were smaller group or just two of us, so I told hime to ride a little more to find out if no one was around, and we could go to the water just in regular underwear. On our way we passed around a place where we usually were changing and drying our cloths after swimming. It was between some trees and bushes, perfectly covered from all sides and also from above. I told him we could stop there afterwords, as we usually did with the other people. We always went there and take all our cloths off, boys at one time, girls at the other. When we finally got to the beach we found few people there, but luckily they were just leaving at the moment. Finally it was empty, we only saw the group of people at the opposite shore. So we went to the water in our underwear and stayed there good half hour. At some point during that time I started to have very resistent erection, what was quite visible when we were returning to the beach, so I lied on my belly to cover it at least little bit.  He saw I was excited and while we were drying on the sun he asked me whether I was still masturbating. So I told him I was and only then he admitted he was doing it too. The he asked me whether I was using porn to it of what I did fantasize about. He said he was reading stories or wathing porn when alone at home. I told him I usually think about some things that happened and it reminded me to one story which happened right there by the lake one year before. Once we were caught by a storm, so we ran with six or seven girls and boys to that changing place because it has the natural roof provided by the trees. Nevertheless it was a very strong storm so we got there completely wet. We waited a while and then somebody suggested to strip nude and not to stay in those wet clothes. We did it in a shy way, not really seeing much and stayed covered just with towels and were chatting. Nothing would really happen until we spotted the parents of one of the girls went to save us. They were quite close so someone just said we have to get our cloths back to us as soon as possible. And then we saw us all naked while changing, the girls and boys fully nude, with trimmed pubes or the bush, beautiful tits. It wasn't really sexual at the moment, but it became my major fantasy for a long time. By the time I was finishing the story I thought I would just cum without a single touch. I asked him how often he does it and he said almost daily, so did I. Then he asked whether I did it earlier that day and I answered that not yet. At that time I was sitting down with a huge boner in my pants and so was he. Without any special suggestion I just got naked out and started to masturbate right there, no one elso was around so he joined me and we both came in about a minute to the grass. After it a bit weird thig happened. We went to the water fully nude to swimm a bit more and to clean ourselves nad on the way back we saw a fisherman sitting near our place - he could have been seen only from the water and probbaly heard all of my story. We felt very emabarassed but later we realized we just talked about the story, nothing else really could be heard or seen. And we didn't know the person, so it wasn't that bed. The other days we always went there with other friends of mine, so we didn't masturbated outdoors. One more time we did it late night while in bed, talking some other dirty stories.
