Your hot stepmom informs you that you got her pregnant. Your worthless father didn't have it in him, and she is so happy to have your young seed growing inside her. She is so horny from the pregnancy and it turns her on feeling your seed grow inside her. The idea that your virile young seed is stretching out her belly is too hot to handle. You oil up your stepmoms belly before she pounces on your cock and rides it to completion.
