You are so attached to your step-mother but time is going and your real step-mother became old ugly and weak. I will replace her, you need a young sexy step-mom who knows how to take care of you. I humiliate your old step-mother in different ways, say that if she tries to take you back from me I will beat her, I show my muscles to prove how much stronger I am. I make you have sex with me to claim my right over you, now you are mine and you are forgetting your old step-mother slowly slowly. I make you repeat that you belong to me and make you cum inside me.
