Confuse about wife fantasies

Hi ever one i hope to get some answer that may help better understand my wife if she is just talking fantasies or if she may be willing to carry out those fantasies.

here is our deal for the past several years my wife and I will not have sex unless we are talking about a third person involved, preferably a black guy to give her her very first time experience, we have a friend that that that we talk about it doing it with in fact last year we got real close I think we went to the lake and my wife intentionally let her bikini little loose to the point he was able to see her private i have spoken to my friend about it and he is actually excited about the idea of doing my wife, my wife is all forward during the heat of the moment to the point she tells me to go head and set it up but when she is not on the heat of the moment she is not forward..I personally think she wants to do it but she also express moral concerns about doing it can any one give me any advise what you think? summer is coming up and I want to try this again by the way getting her drunk is not an option as she doesnt drink please let me know. Is this normal?
