re: Can a woman fucking with more than 4 blacks men in one night?
Not only that, it is possible a woman CAN be impregnated by more than one man when having sex with multiple men. This is called superfecundation twins: when a woman has intercourse with two or more men in a short period of time while ovulating, it’s possible for her to be impregnated by two or more men separately. Thus she could have one black baby and one white baby at the very same delivery.
Superfecundation conception happens about 2% of the time a woman has multiple sex partners during ovulation. Unfortunately (or fortunately, however you look at it) most don't come to full term.
Imagine, however, having a half-twin paternal brother or sister who is of a different race than you. Interesting. Makes cuckold sex, where the spouse has sex with his wife afterwards, very intriguing.
