I never thought going to Y could lead to so much fun.
I joined the YMCA a few years ago to help me get more exercise. After working out one day I decided to take a cool shower and step into the steam room for a while. I sat in there a little while and since I was by myself I started to touch my slowing growing cock. I was enjoying the feeling of doing something like this in a public place but before I could get fully hard another guy walked in. I stuck my mostly growing cock in between my legs. Not so far that you couldn't see it but far enough that it didn't stick up. The guy who came in sat down right next to me. I sat there just looking ahead of me trying to get my cock to shrink. I noticed that the guy next to me was leaning right in front of me and looking down at my cock. I got bold and said, 'If you want to see it here it is!' I lifted it up from between my thighs and laid it on my lap. The next part shocked me. He reached over and grabbed my cock and started stroking away at it. I looked into his lap and he was fully hard but had the smallest cock I had ever seen on a full grown man. Fully hard it was only about 4 inches and as big around as my middle finger. Mine is thick and almost 7 inches, which he commented on. I grabbed his cock and started stroking away at it too. I couldn't hold myself back because I was so horny since I had warmed up my cock before he joined me and I soon shot a nice load all over my legs and the floor of the steam room. I got chicken after that and quickly rinsed off my legs and the floor and went to showers.
A few weeks later I was in the showers on a Saturday morning and was just finishing washing. I looked over a an older man who had just walked into the shower area. He was short and a bit heavy. His cock was small with just the tip sticking out of his really dark pubic hair. He got in the shower right across from me and was soaping up. While doing this he kept looking at me and especially at my penis. He reached down and started soaping up his cock and I couldn't believe how huge it had just gotten. It went from about one inch to about seven and was thick too. He started stroking at his and I started joining him doing the same to mine. Again I came way too fast shooting a load on the shower floor. We did this with four other guys in the showers. The showers have dividing walls and they had their curtains closed. I watched him as he came too.
Since then I have seen many guys in the steam room and showers both hard and getting hard. Some try to hide it. Most don't. I actually had another experience in the steam room but that is not for this site.
I would love to hear about any other guys or gals at the Y that had similar experiences.
