Not one for using public toilets when out shopping, unless very urgent. In town the other day when I really needed a leak, so made my way to the nearest loo. On entering was immediately hit by the strong odour that these buildings have. Moved to the trough where there were three guys standing. Struggling to get my cock out without peeing myself and keep hold of my shopping bag was not easy, relief at last as I started pissing. Now this had taken a while and I could not help but notice that no one had moved away from the trough. I glanced to my left and was greeted with a hard cock being stroked, to my right side the same was happening with the fellow standing there. I could not see the third chap but could see his arm moving in a not unfamiliar way! Now in all my years I had never experienced a scenario like this before. Obviously I know that things go on in toilets but assumed it took place in the cubicles, not out in the open like this. By now I had finished pissing and was shaking the drips off when I realised that this was turning me on. I looked again at the two guys either side of me, they were both openly wanking their stiff cocks. My own dick was now starting to respond to my rubbing, the chap on my right side reached over and gave the wanking gesture and beckoned me to move closer. I just stood there frozen not knowing what I should do and terrified of being caught! I moved slightly backwards so that they could all see that I was as hard as I could be, I then put myself away. Quick wash of my hands and I was out of there, great regret, but scared to be seen going back in again. So off home for a bloody good wank and mega cum! Interested to know what the form is when this happens, as not a word spoken by anyone. Is this a common occurrence? As said I very rarely use public toilets, but this has lit a spark.
