Wife and I were in San Francisco staying at a hotel. One morning we were heading out, and she forgot something so went back to the room while I went ahead to get the elevator. Along the hallway I heard a couple going at it, and managed to get this recording before my wife returned. She had no interest in listening further and said I was sick for listening at all. A shame too, as based on this small sample I think it would have been a great session to hear fully.
