People are getting watched while they are having sex. They might be getting filmed, they might be getting photographed, they might have someone in the room watching them. Either way, people are having a naughty time while having their most embarrassing moments getting seen.
Couples who can do it all night. Pairs that can have sex again and again. Horny as hell. When "One more round" means "100 time mores". When one has a lot of stamina, someone's ass is in trouble.
