I'm married for 12 years and have had cuck fantasies for 10 of those years. My wife knows the details and uses it as pillow talk to really get me off. We play around with the idea but she isn't so sure about trying other men again. (We did a mmf threesome with a guy 2 times years ago). Her biggest concern is that she worries about getting romantic feelings for a potential lover and my fear is losing her heart. I told her I would share her body with men of her choosing for her pleasure and my enjoyment but only if she'll make it about sex only and maybe a friendship should there be a regular guy. She has concerns about the unknown and so do I. My question to the ladies and men who have a lot of experience is this. What can I do, we do, if anything at all to eliminate the possibility of that happening? Should we try another angle or leave this as strictly a fantasy?
