I admit that I read a story on another interracial forum about a white couple who went to Africa because of the husband's work, the wife was bred multiple times by the black housemaster and once by another dude
They were using birth control at first, but when it came time for her to resupply, the female doctor conspired with the housemaster to give her fake pills. As such, the wife was soon pregnant by him.
At first the couple was upset, but they had the baby anyway. The wife was bred 3 times by the housemaster and the babies were given to the housemasters wife to raise.
Don't know whether the story is true or not, but I found it very hot regardless.
