More than a couple of taboos involved here. For married women, it is the taboo of sex with someone other than your husband. For the husband, it is the taboo of watching and or encouraging your wife to have sex with another man. And, of course the taboo of interracial sex.
A lot of the men I have had sex with get a great thrill out of fucking a married woman. They must, given their reactions to seeing my wedding band against their cock. And the number of times men have cum all over my ring.
And when I let a black man know I'm interested in him, you can see his lust burning.
No love here. Just lust. I'm his fuck toy. He is mine. My lovers that I see on a regular basis share an ongoing lust. Love of lust if you wish.
