Help step-mommy get pregnant again - your step-Mom has been trying for months and months to get pregnant, but nothing seems to work. You come home today and find her sobbing in the living room. She's very upset, she questioned your step-Dad about not getting pregnant, and discovered that he had undergone a secret vasectomy procedure, behind her back. So all her efforts were for nothing, they can't get pregnant anymore. Your step-Mom wanted to extend the family, she wanted to give you a sibling as well... you realize that you're the only one around who can help her accomplish her mission and decide to help her. She is reluctant at first, but she soon gives in, because she is ovulating, and because, after all... it stays in the family! She sucks your cock to get you hard, then you fuck her. Once you're done, you both contemplate future plans...
