It was 12.30 and I was on the last bus home, me, the driver and another bloke. Getting off at the last stop I really needed a piss so I went to the nearby public toilet, the other bloke followed me. When inside I got my cock out to piss but a twenty somthing guy came over to me and asked if he could hold my dick as I pissed! I thought it was a wind up, but he took me in hand as I pissed. I began to stiffen as he slowly wanked me and whispered in my ear that the last squirt of piss in his mouth would be payment enough. The other bloke heard all of this and enquired to the young guy “can I be next”. I was now very stiff and nearly finishing my relief, when the young guy got down on his knees, took my now erect cock in his mouth, and drank the last bit of piss. It was heaven. The other guy, who was now very excited said “me now I believe” and produced a cock that was bigger than any I had ever seen, and I have watched hundreds of blue films, the young guy was in awe! He said that as he was “special” and would he mind doing his business in private? He said O.K., and I was invited to the disability cubicle as there was more room for the three of us. The young lad, when behind a locked door, stripped down to a basque and fishnet stockings then asked me if I would come in his mouth, whilst the other guy gave him the fucking of a lifetime. He had already given me a few strokes so I thought “why not”. The other guy went to the sink and covered his cock with liquid soap, and started to pump away at the young lad who was now giving me a very expert blow job. I came in a matter of minutes and when the young lad swallowed it all, he turned to the other guy and begged him to come all over him. This he did and what a cum, it was like a fountain! The young guy then proceeded to lick both of us clean (with plenty of tongue in and around the rim of our arseholes). We then dressed and made our way home. I have since heard that this is a normal exercise for the pair, they just like to have someone watching.
