Your step-sister has worked out your fetish for a woman in charge, and she's toying with you. She tells you to get your cock out and stroke to her while she flashes her tits at you. She lifts up her top for you, laughing and teasing you with all the things you most desire - a woman who knows what she wants and how to get it from you. She makes you start and stop stroking at her demand, and you obediently submit to your step-sister.
