A missed oportunity

Theres a place in the woods I can sit in my car and eat my lunch when Im in town . I was there last month and it was pretty busy mostly dog walkers and then a van pulled right beside me and a guy says his slut girlfreind needs a good fucking and asks if Im interested . I can see her sitting in the other seat looking down with a smile . I was so suprised i said something stupid like Im good thanks and he said sorry and drove away . My instantly hard cock made me want call them back but they were gone . I didnt like him calling her a slut but it looked like she was into it and now all I can think about is getting freaky in the back of a van with a hot girl while her guy watches and hopfuly joins in . Next time I better think before i reply ... :(
