I live in a part of the USA where there are a number of "primitive" rest areas along various highways. This typically means there is a parking area for cars, another for trucks, maybe a kiosk with a map and a trash barrel, but no bathroom facilities.

One night this past summer my girlfriend and I were driving home from one of our favorite nude sunbathing spots. I tend to drink quite a bit while at the beach so I'm always needing to relieve myself by this portion of our journey. This rest area has separate parking areas for trucks and cars. I pulled into the parking area for cars, shut my lights off, and walked into the patch of woods that separates the two areas. I settle on a tree, take my dick out and unleash a torrent of piss. As I'm doing my business, I look through the trees to see a pickup truck parked in the truck parking area, probably about 50 feet away. There is a woman bent over the hood with her dress hiked up and a guy railing her from behind. My hand quickly goes from shaking my dick to stroking furiously. They must have just finished up as I noticed the guy slowed down and was giving her a few gentle pumps before pulling away. It took me all of 30 seconds to blow one of the biggest loads I ever have all over the tree I was pissing on. I put myself back together, got in the car, and we drove home without my girlfriend ever knowing what I had just watched and done. I can still remember the intoxicated feeling I had for the entire trip home.
