After an intense argument, the teen step sister, still wearing her pantyhose, storms off to her room. Her pussy is aching for release as she slams the door shut. She yanks off her clothes and impulsively rubs her pantyhose-clad crotch against the wooden floorboards, moaning in pleasure as the friction builds inside her soaked panties. She kneels on the bed, spreading her legs wide in invitation to the forbidden act. She slowly peels off her pantyhose and tosses them aside, revealing her wet and ready pussy, covered in cum from her earlier masturbation session. As she tentatively fingers herself, imagining her step brother's cock filling her up, she hears a knock on the door. It's him, aroused and ready to claim what's his - his sister's tight, untouched pussy.
