I almost always take my lab for a ride everyday,Sunday we went and after I had a couple drinks I needed to stop to whiz, I stopped at a rest area a few miles out of town and it was pretty empty for a Sunday evening. I went in, there are 6 stalls and I went into the 4th, I noticed that someone had cut about a 5" hole between 3 and 4. Just wondered who had the time and balls to do it. As I drained my bladder I heard the next door open and close, I saw the shoes under the wall and then to my surprise and pleasure a nice hard cock appeared thru the hole. I'm guessing latino due to the skin, he was probably 7" but so wide in girth, I could not resist. I touch him and started stroking his hard thick cock, I sat down on the toilet for a better view and continued to stroke him. He moaned a little but not a spoken word. It only took about 2 minutes and he shot cum across my lap and legs and then pulled away. I said wait I'll clean you up but out the door he went. I used some cum to stroke myself to and nice hand job and then left myself.
