As I've said elsewhere on here my best friend fucks my wife while I watch. Such a turn on, the two people closest to me enjoying good fucks and I join in if I want to.We never wanted to include friends or family but were lucky in that we have a widowed neighbor who we knew casually, that has no interest in a "relationship" other than great sex with a hot woman. Which he has with my wife, on a regular basis. And I get to watch so it is win, win, win !!!!
