A man let his friend go to bed with his wife to perform as Husband, wife, and lover

A 18y.o teen cheats on her husband by getting a friend of his to sleep together with on a trip his back. This is seen as an older man looks on as his wife services the intruder sexually and giving him a wet kiss before taking his penis into both of their mouths and sharing it in what can only be described as an oral sex one on top of the other.
