Diana Grace, the naughty step-sister, finds herself alone with Tony Profane, her step-brother. She can't help but fantasize about his cock, her pussy growing wetter by the second. She starts touching herself, but Tony catches her in the act. Instead of being shocked, he joins her, his massive cock hardening at the sight of her. They fuck passionately, Diana taking every inch of him, their moans echoing through the house. Just as they're about to reach climax, they hear someone coming, forcing them to quickly separate.
