Prequel to 'step-Sister's Turn to be Bred' (also sold as one whole movie). Your step-mommy greets you, 8 months pregnant, and tells you it's time to breed your step-sister too. How sexy will it be knocking up both your step-mom and your step-sister together? I strip naked and have you fuck my body, lots of taboo talk involving step-mommy and step-sister. I tell you not to cum, and to save your big load for your step-sister.
