You and stepmommy have been having an affair for a while now, in secret of course, and always taking the necessary precautions. Condoms, birth control, pulling out. The last thing either of you would want is an unplanned pregnancy that gets people asking questions. At least, that’s what you thought. You come home to find stepmommy waiting, dressed in something extra sexy just for you. She comes on strong and who are you to turn down the perfect welcome home, until it gets to that point and you go to reach for the condoms. And stepmommy says no. She explains that her best friend just announced an unexpected pregnancy and she hasn’t been able to get the thought out of her head ever since. Maybe it’s her time of the month, or the fact that she secretly stopped her birth control and is now ovulating, but stepmommy's feeling fertile and horny and she just NEEDS to breed.
