Not the last time
Last summer whilst driving home I started to get my cock out as usual, I often do this as it was exciting. As I drove along I would slide my chair back and recline it slightly and pull my shorts down. I would get it hard then as I passed a woman driver I would slow down hoping she would see me, sometimes this happened.
Anyway I was getting quite horny and wet, my juices flowing I pulled in at a layby, it was very dark with no one around, I could see for about a mile in both directions so I decided to strip right off. I got out of the car it was so nice to be naked along a road I traveled along most days.
By now I was ready to cum pinching my nipples hard and gripping my cock tight. There I was wanking off in the road when all of a sudden I came, spurting my spunk all over the road. After the last drop I got back in my car got dressed and drove home. The next day as I drove past the spot it got me hard again thinking about I must do it again sometime.
