It’s a tie for me. My wife and I had sex in the middle of small retail shop I worked in after close. There was a couch in the middle of the store and we were and 10-15 ft away from windows all around. People walking and driving by the whole time and could see everything if they had bothered to look. The other time was on my father-in-laws kitchen table when he ran out for groceries that we later ate on that table.
