This is totally true.
I had to take a short trip the other day. About an hour from home I got the urge to play around in the car while I drove down the road. Well I was on the way back home and I had my cock out playing with it. I was really horny because I had played with it the whole way there and hadn't cum. I really had to piss so I decided to stop at this rest stop along the highway.
I must say that I'm turned on by pissing in public restrooms, especially with a guy next to me. But never dreamed of it ever going further than a dirty fantasy.
So I pull into the rest area and put my semi hard cock back into my pants. As I park I notice an old man sitting in his car. I think nothing of it and head on into the restroom. Inside the restroom there are two urinals and a stall. I step up to the urinal closest to the stall and pull my dick out. I pulled on it a little so it would be nice and dangly if I got any company.
Well after just a few seconds the old man enters the restroom and gets right next to me. I must mention that there was no divider between us. I was still horny from playing in the car so I started to get a little hard. I was really nervious or I probably would have got rock hard. Almost instantly I felt his eyes on me, so I started to glance his way, only to find that he was totally staring at my dick. He had his out it wasn't as big as mine but his had a big nice head. He was just kinda lightly stroking his dick, it wasn't very hard. So I started pulling on mine, and shaking it. I was staring at his and he was staring at mine. He was kinda groaning and licking his lips, while I was totally quiet.
By now my dick was fully hard and I was as horny as hell so I just grabbed my dick and started stroking. At this point I don't think he knew what to do, because anyone could have walked in at any moment. I just kept stroking and looking at his dick. He must have got nervious because he put his up and stepped toward the sinks, but kept watching me the whole time. Finally I went over the edge and pointed my dick down toward the pisser, and his eyes were glued on me as my cum started flowing out of the head of my dick. you could hear it as my thick hot cum splattered into the metal pisser. After I shot most of my load I flicked the cum off my finger, and put my wilting dick back into my pants and walked out. He watched it all and I never said a word to him.
As I left I couldn't believe that just happened.
I bet he nearly pulled his dick off beating it thinking about that. I know I did.
