hi
have had this happen some years ago, my wife had had lovers before, but the way I got her to have my mate was by first when we did it pretending it was him. After a lot of this and winding the both of them up about it, I spoke to him and said about how it was ok with me, because as he was my best mate I felt I could trust him not to try and steal her. The deed was finaly done while I took my mister shopping, it did get very intense for a while, but to be honest a big part of cuckolding's attraction is not being totally in control and also the fear that she could choose him. lasted for years and we are all still friends.
