Need Help Finding This Yaoi

All I remember is the seme had a girlfriend and a boyfriend. The three of them had sex together. The girlfriend and the uke had a conversation after about how they have to share him because he needs lots of love or something like that. I think the seme's name might have been Maya. In the end I think the seme chose the uke and the uke might have gotten slapped.
Please help I am dying to read this again.(￣∇￣")
