This happened in January of this year
I went to the local YMCA this year because I wanted to run, I could have done it outside but it was so chilly out there. When I arrived at the YMCA I paid my small fee and proceeded to the locker room to change into my running gear. As I entered the locker room all I could smell was the familiar smell of sweaty jocks and chlorine from the showers and was kind of turned on by it. So I changed and went to the indoor track to run, I started to run but all I could think of was the locker room and being seen nude in there, I am really enthralled with my penis it's about six and a half inches when erect, and love to have people see it both limp and erect.
Well I could only run for about twenty minutes before I started to get really horny, so I went back to the locker room to shower and hopefully be seen by someone. Let me describe the locker room for you first so you can get an idea of what it is like in there. First off there are two ways of entering the locker room, one is from the main hallway which goes straight into the locker room. The other is from the pool through the shower and toilet area and into the locker room, this is why I like to shower because when someone comes from the pool they have to walk right past my nude body. Ok so I got undressed and noticed that there wasn't anyone in the locker room so I kind of admired myself in the mirror a little and then went to the shower.
I like to stay in the shower for as long as possible, hoping that someone will see me, well on this occasion it didn't take long for me to get erect. I stood in the shower with a raging hard-on and couldn't hold back from stroking it, so I shut the shower off and went to the empty locker room to start stroking. Sometimes when I am jacking off I like to lean up against the sink and have my balls rest on the cold porcelain, and this was one of those times. I started to jack really hard while I was leaning on the sink when I heard some voices from the shower. Just as I stopped jerking two pre-teen boys walked by staring at me and my hard-on, I know that they knew what I was doing but I didn't care because I was really close.
So as they passed me I could hear them say 'did you see the size of his dick' and 'I think he was masturbating'. Well that just sent me over and I started jacking again just after they were passed me, I was even more horny now so I turned around and leaned my ass up against the sink with my hard-on out and open to the public and started to jack really hard, pre-cum just going everywhere. As I looked up I could see the two boys watching me around the corner of the lockers, so I continued to give them a show that they wouldn't forget. I just stood there jerking really hard and kind of moaning and rubbing my balls when all of a sudden I started to tense up and shot three heavy thick white loads into the air and onto the floor. It was so erotic that it took me a few minutes to recover, I just stood there, the two boys walked by while I was standing there trembling and just kinda smiled as they went by. I quickly got dressed and left hoping that I wasn't going to get busted for this in a public place. This is by far one of the best jacks I had ever had, and hope that I can do it again sometime, but for now it is a good memory to jack to.
