Has anyone ever played with themselves to the sound of other people having sex say at a party or something? We had a party here, small thing, my friend brought over this little petite girl, he slammed her for 2 hours straight, she was getting pounded. I couldn't help but hear her scream, I wanted to whip it out right there!
Does porn count? A I was at a gathering of friends (not really a party, much like what you described actually) and my friend D brought his girlfriend over and they ended up banging multiple times on the inflatable mattress like 3 feet away from me. It was dark and I guess they thought I was asleep...Didn't turn me on, it was just awkward because I couldn't see anything and all I could hear was them thrashing about and the occasional muffled moan.
