The biggest dick I ever saw was at a Penn Station urinal in Manhattan. I had a craving to see some cock, and I was in the neighborhood, so I stopped to take a leak. There was a guy who was standing at a middle urinal who looked at me as I walked in, I thought it was a good sign, so I walked up to the urinal beside him. He was a tall, well built guy, dressed in a suit and a big overcoat with a belt, kind of covering him like a cloak. He had dark wavy hair and a smile framed with a mustache. As I unzipped and started to pull out my dick I looked over and he was stroking a semi that was thick and long as a python. He didn't mind me staring I guess, he was getting harder and it wasn't long before I was at full mast. He kinda turned in my direction, still behind his coat so I could get the full view. There were guys coming in and out of the restroom, but in a situation like that I don't care who sees me looking, nobody knew me there anyway. My cock was hard, my knees were shaking my mouth was dry, and I was breathing a little fast. This guy liked to be watched. He stepped a little closer to me and swung his dick a little and said, "You can touch it". He was so huge. He had a cute face, so tall, and the clothes were a real turn on. I reached over to feel how thick he was, way bigger than me, he seemed to like being appreciated. I got my feel, and started to get nervous. I stuffed my hard-on back into my trousers sideways, and flushed. I got another look at his beautiful face, and I walked out into the crowd.
