I have had an open marriage for almost ten years now and we have had a few play sessions together, but had the most fun playing separately and coming home to show the evidence or tell the story. We recently decided we wanted more regular side partners, which is fine with me, but she found a very nice couple looking for a Unicorn to be a companion to the husband while his wife has her own favorite friend that they all go out with and play. The role my wife would play is as slave to this man who will buy her nice clothes , shoes and jewelry to go out to nice restaurants and fancy hotels to play. The deal is that she has to agree to be trained by him and eventually she can play with the entire group. I would get whats left of her at the end of the night or next morning with pics and videos of how she was played with earlier. My wife is excited about the prospect, since she loves being submissive, but she hasn't been submissive to this extent and I am concerned that she could get very attached to this new intense lifestyle. I was used to the have fun then come back to reality play style, but this is something new altogether that I dont understand at all. What are the emotional land mines I am allowing to be set , it seems much deeper than just sex. Am I over thinking this or am I really very lucky and going to have the most amazing future time with my wife? Would love all your input before it goes too far or is stopping this from continuing more detrimental to the marriage and I should trust in our ten year success record.
