I was traveling home from work one evening on the bus. I always sit in the back row by the window. We were stopped at a red light and I looked down into the car beside us. There was a guy in the car with his pants down around his ankles pleasuring himself in full view. I got so turned on by this that I pleasured myself as well. I wanted to jump off the bus at the next light and get in his car, but he was gone.
