I have heard others having sex several times. Usually it was not a turn on...except for a neighbor that I lived next to in an apartment 20 years ago. His bedroom was next to mine. I didn't usually hear anything through the wall, but when he started fucking his girlfriend late at night when the traffic in the street was quiet I could sometimes hear her...what a turn on - it was so hot.
He was a small guy, maybe 5'5", but he must have been hung like a horse. She would moan softly and talk about how good it was and how big he felt - in a way that I knew she meant it. She wasn't loud. It all sounded so natural and real. That was what made it so incredibly hot. I never heard a thing from him.
This happened about 10 times over a period of a year. It was one of the hottest, sexiest things I've ever heard and it used to drive me crazy. A few times my girlfriend of the time was there, too. The both of us would just lay there, listening, until it ended. We would both get very aroused and always had sex afterwards - quietly.
Great memories - I'm getting horny just thinking about that. | 
With a card, " The night time is the right time but it will be fight time if you dont use this present immediately" LOL!
