In an intense display of dominance, the brother forces his sister to her knees, her mouth stuffed with his hardening cock. He fucks her face mercilessly, making her gag and drool. Turning her around, he slaps her ass, leaving red handprints as he pushes his thick cock into her pussy, making her moan in pain and pleasure. He pounds her hard, her tits bouncing, before pulling out and coating her face in his hot cum.
