You go round to your Step-Parents house to surprise them with a cheeky visit to find your Step-Mommy all alone. Your Stepdad has gone on a "last minute" business trip. Normally your Step-Mommy is happy to have the house all to herself and some peace and quiet but this time she looks subdued. She denied there's anything wrong to start with, but then comes clean that her and your stepdad have been trying for a pregnancy. But every time your Step-Mommy is ovulating he is going on all of these last minute "business trips" so haven't had much luck in getting pregnant. Step-Mommy is paranoid that he is either cheating on her or lying to her about wanting another. You think about it for a minute. Your Step-Mommy has been so good to you and you love her so much for all of the things she has done for you over the years. So you offer to impregnate her instead of your StepFather. Step-Mommy is shocked at first, she's right it is wrong but if she wants to get pregnant that bad she will do anything right? As soon as Step-Mommy sees how big you are now and how hard you are for her she goes from reluctant to a taboo loving freak. Riding that cock and draining every last seed from your balls. You push that cum so deep inside of her fertile cunt that you are almost 100% sure that you've got her pregnant. Maybe she should just fuck your stepdad off and the two of you can start your only little Step-Family instead? *warning - vid contains strong language, HEAVY use of taboo trigger words and loads of impregnation dirty talk.
