I was on my way home and needed a pee. I ran in to the train station toilet and headed straight to the urinals, luckily there was one vacant. I took my cock out and proceeded to do my business, I way peeing for ages and had not noticed the old bloke beside me looking at my cock. "you needed that did'nt you" I just nodded. "nice cock as well" I just smiled and shook my cock and put it away and walked out of the toilets. As I was walking to the train I could feel my cock getting aroused thinking what the old guy had said. I turned back and went back in to the toilets, the old guy was still there at the same stall, I stood beside him and took out my semi erect cock and stood there pretending to pee. He again looked over, but gasped this time as it was now almost fully erect. He looked at me and said for me to follow him. I followed him down a dark alley way, then he stopped and turned round and grabbed at my cock. He took it out of my pants and wanked it till it was rock hard. "beautiful" he said as he took it in his mouth. He sucked on it and squeezed my balls, rolling them about between his fingers.He was taking most of my six inches in his mouth, I started to fuck his mouth and my fucking was getting faster, so he sucked harder and my cum shot right down his throat. He just swallowed it all, not taking it out of his mouth. I leaned over to touch his cock but he said "I hope you enjoyed that as much as I did" I nodded as he turned and walked away. I have been in to the toilets again but the old guy is no where to be seen. Pity.
