It's so good to have you home step-son, step-mommy's missed you so much. She gives you a lot of praise about how proud she is of you, asking about your new job, telling you how handsome and wonderful you are. You've made her such a proud step-mommy. But it's hard for step-Mommy to be home alone, all by herself. She'd really love to be a step-mommy again, but step-dad is always working late and doesn't seem interested in her anymore. You say you have an idea. But step-mom seems surprised and shocked - you can't get your own step-mother pregnant. Do you even know what we'd have to do to make that happen? We can't do that step-son, that's taboo. She thinks about it for awhile, talking through if it's something you could do. She asks if you're sure want to be taboo with your step-mother and breed her. Maybe we could try it just once and if you get her pregnant then it was meant to be. step-Mommy takes you to the bedroom, she wants you to breed her. step-Mommy is nervous but excited to be bred by her step-son. step-Mommy unbuttons her top and takes off her apron, telling you to take your pants off. And then she's surprised about how big you are, much bigger than your step-father. You're already hard for step-mommy, aren't you? step-Mommy reaches for your cock (off camera) and strokes you, while touching her breasts. This is turning step-mommy on so much. step-Mommy then gets on top of you (no penetration seen) and rides your cock, while dirty talking to you. Then you get on top of step-mommy (dildo used, penetration seen) and fuck her until you both cum. You're going to fuck step-mommy every day until you breed her and give her a nice, big belly. Trigger word used throughout.
