You come home from being away to a big surprise... your sexy stepmom is pregnant! That's not even the biggest news... she reminds you about that night things got out of hand between the two of you before you went away, and gleefully reminds you by giving plenty of details. You're not sure where this conversation is going, until she reveals that you are the father! No worries though, she's totally cool with it, and your dad has no idea it's not his. Obviously his sperm wasn't strong enough, but yours is! She's thrilled to get pregnant at her age and never thought she'd be lucky enough. As she's giving you the news and rubbing her very pregnant belly, you are visibly turned on. She tells you to pull your cock out. Don't worry, your dad is still at work for a while, and she's pregnant and horny and wants to watch you stroke it until you cum. She talks about your night together in more detail as she encourages you to show her more of those strong swimmers....
