She lists every reason she hates it. The girl dresses and acts like a slut. She is only trying to get attention. You are still a virgin, and step-mommy will not let you waste that on her. Step-mommy says she wants the best for you. She says she is the one who has always looked after you. While she talks, the neckline of her top keeps slipping, and she does not fix it.
Later, while step-dad is taking a nap down the hall, she comes back. This time she is not asking for a conversation. She sits on the edge of your bed and tells you she is the right one for you, her step-son. You hesitate. She does not. She says she wants you all for herself, and she already knows you cannot hide that cock. Step-mommy has seen it. She has thought about it. She is done pretending she has not.
She gives you your first blowjob slowly, talking you through it, then pulls you over her and teaches you how to fuck her. Every time you pull back she guides you deeper. She tells you this is how a man learns, and that from now on she is the only one you are allowed to fuck. Not the girlfriend. Not anyone else. When she feels you getting close she locks her legs around you and demands the impregnation. She wants your seed. She wants you to make step-mommy a step-mother again, while step-dad is in the other room and never finds out who bred her.
You leave her filled, claimed, and already talking about the bump she expects you to give her.
