Before we were married my husband and I were having sex in the car at the end of (what I thought) was a deserted parking lot. It was late, dark out and we had sex in that parking lot a few times before so we figured it was ok. So there I am with my shirt and bra in the back seat, feet up on the dashboard, he's on top of me with his ass sticking straight up and a car pulls up next to us. 3 people got out and stood there talking for a few minutes, I choked back a laugh, he stopped moving and said "I think I'll stay right here". Guess we had steamed up the windows enough because they never noticed, eventually they left and we got back to business, but holy shit was I glad he was on top!
