As the clock strikes midnight, stepbrother and sister find themselves alone in the house, bored and restless. Their eyes meet, and a silent understanding passes between them. They retreat to her room, their hearts pounding with anticipation. She strips off her nightgown, revealing her naked body, and he follows suit, his cock already hard. She lies back on the bed, spreading her legs, and he moves between them, his eyes locked on her glistening pussy. But tonight, they crave something different. He lubes up his fingers, teasing her asshole until she begs for more. He replaces his fingers with his cock, pushing slowly into her tight ass, filling her completely. She gasps, her nails digging into his back as he begins to move, fucking her ass with long, steady strokes.
