My wife has previously cuckolded me with 3 other guys but each time met them alone. We have had a break for a year but are now looking again. In bed I am telling her I want her to work towards ultimate cuckolding. What is this in my mind?

We have a long-term arrangement where he is her boyfriend. She goes on dates in public where they can act like a couple ( risk of being outed is scary but hot ) They fuck at our house in our bed. He is the man of the house she is his and I sleep in the spare room He always cums in her to assert his ownership and they both like me to clean up (no pregnancy risk for us) If he is black this adds to it as it will be more obvious what is going on

Has this arrangement worked out for anyone ? Is this ultimate or are there any other ideas to add?
