Hi, Few months ago my bf suggested that I should have sex with a black man, his fantasy. He thought this would be a one time thing but I got hooked. I keep having sex with the black guy and It has been going on for a month now. In the beginning he was supportive, but now he is getting jealous of the fact that I prefer black and do not enjoy sex with him anymore. So he asked me to stop, which I tried but could not for long and went back to black. So we had a big fight/argument in which he said that he wants to be part of my sex life. Now he possibly cannot match the physicality and stamina of a black guy and I know that inviting him into sex will only hurt his self-esteem. So a friend of mine from this forum suggested me that I should train him as a cuckold, that is the only way that he will be able to participate. Now my bf is still hesitating but has agreed for now to obey me. So I must turn him into a cuckold. how should I start ? Does anyone have any idea or experience in a thing like that ?
