I used to drive long car trips (8-10 hours) by myself to get to college. To keep me awake on the road and to pass the time I would pull out my cock and slowly stroke myself to the delight of the truckers near me. I loved that they could see my hard dick as I pumped away in my car. As I came I would lap up the precum and cum since I had no way to cleanup at 80 miles an hour. Occassionally I would pass a trucker as I slowly licked the white thick cum off my fingers. I would usually just have to cum again.
