While in Germany, I used to go to a pool in the German village. Most German villages had excellent facilities. This pool had little, single changing rooms that you changed in at the front, when you first went into the facility. After you changed you went into the pool area. I guess this was so both sexes could change privately or whatever. However, in the summer in the outdoor pool there were people who changed in the open.
Anyway - I was looking around and there was also a larger locker room that was used for teams to change in, meet in, etc. This room was awesome and I started going in there to change when I went to this pool. I'd go through the small, single changing room and then walk over to this larger room, go through the door (it was always unlocked). I didn't know what the sign said on the door but it had a picture of a dude so I figured mens room.
One day I went to the pool and I started changing (I always was alone in this larger room) when guys started pouring into this room in their speedos. It was some kind of team, all young guys about my age. They were friendly, just said "hello" and went on their business of stripping naked and horsing around. It was amazing! The slim, swimmers bodies and cocks swinging like crazy. There was one I noticed, about 19 or 20, blonde, so hot with a nice, uncut cock. Sweet peach fuzz on his perfect ass. A few of them struck up a conversation with me and were fascinated when they found out I was American. I changed so slow (ha). Good time for sure. Come to find out - they were a swimming team from the local Universität.
