My FWB and I are talking about finding a third. He has a fetish for Asian and I am a vanilla white girl. I could handle being like a “sister” not sure about joining in… probably be more of a non married version of a sister wife, and I think it would be important to establish that if push came to shove, this girl comes first…over the fetish and everything else. The idea of a “toy” sounds intriguing, but I don’t know that I could over the long haul treat someone like they were nothing more than a plaything and not acknowledge a very human attachment. People get attached, fact of life…why temps get cut off if they start talking about relationships…
