My male friend and I (I'm female) have been in a friends-with-benefits type relationship for a quite a while. We have a lot of pretty kinky sex together, and I might get around to posting some of those later on. For a while we'd been talking about having a threesome, it was just a matter of finding someone to do it with. I'm bi, and we weren't that fussed about the gender of the third person. Last week E asked his friend W if he'd be interested in the two of them fucking me together, and he agreed.
