Just had a massage at a nice place. I walked in the men’s locker room afterwards and there were a few guys that just finished their massage too. They had 1 shower that had steam in it too with semi see through glass. I was going to hop in there but another guy beat me to it. So I sat down on the bench and waited. The others already left so it was just me in there waiting. I could see him showering through the somewhat see through glass. I saw his erect cock and it started to get me hard. I couldn’t help watching him and suddenly I saw him stroking his big cock. I couldn’t help myself and so I undid my robe and started stroking my cock as well. I watched him the entire time until I saw him shoot and shortly after I came too. He finished up showering opened the door and saw me sitting there with my hard cock. He smiled and I smiled back. I just got up and said I guess it’s my turn. I turned on the shower and the hot water and steam felt so good on my muscles.
