Blue Monday: to answer your question regarding if fantasize about my wife having female lovers, the answer is yes, but not necessarily in that context, as I enjoy the idea and the whole point is for me *not* to like it for it to become chillingly humiliating.

The idea of my wife having female friends and humiliating me in front of them is probably something I'm more receptive too - but the icing on the cake is for her to have a male lover as it's the true ultimate humiliation (since I'm straight , becoming an object for the man who elope with my wife is quite... intense to say the least ;D)
