In our last year of school we could decide whether we wanted sports / PE to count into our Diploma or not, yet it was still a mandatory subject. I decided against it and got put into a group of 15 people who chose the same as I did. Since it was not a serious thing for all of us and hot summer we decided to go swimming as a group and "work out" there. The open air pool was not far away so we casually walked there.
Anyway, our teacher was younger than most of our teachers, well toned and quite new in the job (I think only a few years in) and in his late 20s, if I remember right 28. Everyone adored him since he was a chill guy and understood us and probably because he was "only" 9 or 10 years older than we were.
Personally, I can't deny not being attracted to him, he was a very handsome man as I already mentioned.
Most of the times he would watch from the sidelines, every now and then he would jump into the water with us and do some rounds. His body was magnificent and wore short shorts lol. His chest was hairy as well as his armpits and he had a nice happy trail leading down to the jewels.
Usually he would not join us boys in the shower and would wait for us to be done and go home so he could have his privacy. Later on I noticed that it was a schools rule he had to obey. Yet one day he didn't...
(I might have to mention that I'm from Germany and that we are usually quite more open in terms of nudity than it would be in the U.S. for example).
That day he swam with us. None of us really looked at a watch and so we forgot time as it flew by. We realized quickly though and everybody was in a rush. Some boys just didn't shower and just tried to get their bus, some others showered within a minute and ran off. I wasn't in a rush since I lived just a few streets down from our school and could casually walk home. Our teacher had a car so he wasn't in a rush as well. It was me and two other boys in the showers, one of them toweling off and another almost done while I just started showering. While all of us butt naked, the door opened and our teacher came in with a towel in his hand. The one boy walked out and wished him a nice day. Honestly I didn't even realize at first that he was in there until I turned and saw him talking to the one boy who was left, I guess just a casual chat while he was getting dressed. With my back (and bare ass) facing them, I tried to mind my business. I heard the door close at some point and thought they both left but to my surprise the teacher was still there. He asked if I was fine with him being there and I said yes. He came to the shower right next to mine and got naked. Of course I had to look and I am sure he saw too. It was thick and uncut, there were pubes, I wouldn't call it a bush but they were not trimmed either. It had a nice length for being soft as well.
I thanked the universe for not getting a full hard on but I was semi for sure most of the time.
He talked about the day and about our upcoming prom and all of that. It was nice, a very casual chat for a not so common situation. But honestly, as much as I wanted to drop on my knees, it was very cool to just be two men who were super open and comfortable in their own skin.
I'm sure he checked me out as well but I knew he had a fiancé who was a woman so probably nothing sexual.
After a few minutes we toweled off and got dressed and went outside again until our ways parted to go home.
Of course I jerked off that evening like I have not touched myself for weeks.
