You and your wife have been talking about wanting to start a family for a while now. One day she tells you she's ovulating and she's ready for you to get her pregnant. You both have a breeding kink and she tells you how horny she's been. She sucks your cock and then rides you in cowgirl, begging you to breed her fertile pussy until you fill her with a big creampie. LOTS of impregnation/breeding dirty talk ;)
