A secretive knock on the bedroom door reveals a desperate, needy sister, her face flushed, eyes wide with desire. She's been thinking about him, about his cock, and she can't take it anymore. She wants him to fuck her ass, hard and deep, to make her scream with pleasure and pain. He's hesitant at first, but her pleading, her promises of pleasure, and the sight of her round ass, bare and ready, are too much to resist. He pushes her face down on the bed, spreads her cheeks, and slowly, deliciously, pushes his thick, hard cock into her tight, virgin asshole. She gasps, her body tense, but as he begins to move, she relaxes, her asshole stretching to accommodate his massive size, her moans filling the room as he fucks her hard, just like she asked.
