Even today I get that tingling in my balls as I walk into a public toilet, just thinking about then first time all those years ago, when as a teen I had my my first sight of a man wanking his cock at the urinal ! I went in to the toilet for a pee, just like every body else dose ever day. The toilets back then were a different place not like the toilets today, they had a smell all of there own and were open 24hours a day. Well this day I walk up to the urinal got my cock out and had a pee, there was a guy to my right doing the same, or so I thought, but you know whats it's like you just have to have a look over and have a look at his cock But this guys was not peeing he was wanking a very stiff cock. Now just to let you know, I had wanked a cock off before, well a few cocks in fact, But this was something else, I was in a toilet with and old man standing inches from me and wanking his cock. I just stood the looking at him I could not take my eyes off him, I went into a trance like state and before I new what I was doing my hand was touching his cock and wanking him, compared to the cocks I had touched before this one was huge a good 6/7 inches long, I wanked him till he shoot his cum into the urinal, then he was gone, not a word was said, he just went leaving me standing there with a hard cock and looking down at his spunk, I reached in to the urinal and got some of it on to my hand and wanked myself off with his spunk on my cock. I had wanked a stranger off in a public toilet, I could not tell you what he looked as I only ever saw his cock, but that was it I was hooked, It was such a turn on doing it in the toilets with strangers so I went back for more. lots more in fact.
