Auto-masturbation, sitzgürtel-fetisch

As I'm pulled over in a lay-by waiting to pick someone up, I get a little impatient. I'm all dressed up in a low cut evening dress and my seat belt securely buckled up. I order to pass some time I decide to have a little fun with myself, I begin rubbing my pussy, caressing myself and enjoying the seat belt pressed against me. I cant believe I'm masturbating in my car by the side of the road, it's such a turn on that I'm cumming in no time.
