I don't know how I missed this one... I'll weigh in. Once in high school I got it on with my girlfriend under a blanket while watching a movie with her parents and sister in the same room. Her sister was actually sitting on the same couch (sectional) that we were laying on. I was mortified when she started, but I couldn't help myself. She was crazy, sweet, and the best girlfriend ever.

Close second: once I was seeing (not dating exclusively by any means) a girl. I was friends with her family. I took her mom's car (a brand new trans am convertible) to the store for some reason, and ran into a waitress I used to know, and took her for a ride. She left butt prints on the hood back behind the boot cover for the top. We were in her neighborhood and it was just dark, just parked in a cul-de-sac beneath a street light and a basketball hoop. It was pretty romantic.
