What is threesome relationship?

A threesome relationship is a complete sexual encounter that involves three persons. Two of these individuals might be in a more committed long-term relationship with each other. It is also possible that all three of them might be coming together just to enjoy and indulge in some casual fun.

However, in both cases, the main emphasis in a threesome relationship is mainly on erotic pleasure and nothing else. This is basically about three persons who join up to enjoy a squelchy and saucy X-rated romp.
