Laughter echoes through the house as siblings Michelle and her stepbrother joke and play, but tension grows as Michelle's eyes linger on his crotch. She playfully pushes him, and he stumbles, his erection tenting his pants. "You're excited, aren't you?" she teases. He confesses, and she guides his hand to her breast, moaning as he gropes her. They strip, and Michelle licks her lips, taking in his thick, veined cock. She strokes it, feeling it pulse in her hand. He pulls her to the floor, and she straddles him, guiding his cock to her wet entrance. She sinks down, her eyes locked with his as she begins to ride him.
