Okay guys we need help with this one:
My wife and I have a mutual friend who we are both deeply attracted to. The attraction goes beyond the basic physical "let's fuck her" we all connect on multiple levels and get along quite well. Our mutual talk is heavily laden with innuendos from all three of us, sometimes they are light and playful and at other times they can be a little more direct. It seems as though we are all feeling each other out (so to speak).
My wife and I are in a stable marriage and we have always wanted to add a third to our relationship, for companionship, friendship and sex. We have been very careful in defining what are hopes and expectations are for each other and anyone we ask to be part of our family. We have children and this relationship would have to meet our strict criteria so that all who are involved are comfortable.
Our mutual friend has been in our life for about half a year now and she meets are criteria. We've discussed this heavily and have decided that she is our ideal for the triad. As I've stated before, we have all been very playful and the talk is quite sexy most of the time, how should we proceed to find out if she is receptive to becoming our third? There is a caveat to all of this, she happens to be involved in a dead-end marriage (her words, not ours). We love talking with her and we have much in commen. Every conversation she is the first to initiate loving statements, or flirty statements and she also brings up how frustrated she is with her husband and their marriage. Any advice?
