You know your step-daddy only agreed to marry me because he thought I could give him another offspring, right? Yet here I am, still not pregnant. Whose fault do you think that is, mine, or your senior citizen step-daddy? Your step-daddy has too much pride to admit that his sperm no longer works, and if I don't get pregnant soon he might divorce me! I know you like having me as your stepmom, so why don't you do me a big favor and put a black offspring inside me? That way, your step-daddy won't suspect I cheated, and if he does a DNA taste it will show that he's related to the offspring. Let your sexy stepmom suck your BBC before riding you in cowgirl and reverse cowgirl, bouncing my white booty on your cock until I milk out your black seed.
