Their is a difference between fantasy and reality. If a woman chooses to get pregnant by her Bull and has a white husband, you either hide from family, "out" yourself and your husband as allowing another man to impregnate you, or develop a cover story. Plenty of stories where the doctor used his sperm to impregnate many women, so a "screw up" at a fertility clinic isn't impossible.
Or you tell your family that your wife fucks other men, specifically black men, unprotected. Also that you know she does that and have accepted all responsibility for raising the product of her wanting a black man to breed her.
I mean some would be that far into cuckolding and breeding. but most would use a cover story
