A voyeuristic stepbrother can't help but peek at his stepsister's nightly ritual. Tonight, she's wearing a thin nightie, her big ass and wet pussy clearly visible. He watches, entranced, as she rubs her clit, her pussy making wet noises, her body tensing as she nears orgasm. 'You like that, don't you?' she teases, noticing his presence. 'I can make you feel good too,' she promises, rubbing her pussy against his cock, but pulling back just as he's about to enter her, leaving him aching and frustrated.
