Location: a cozy living room in the evening with the warm, flickering orange glow of a crackling fireplace casting dancing shadows and soft highlights across the floor
Position: Rebecca lies on her back on the soft rug in missionary, her body arching violently off the floor with her head thrown back as a penis penetrates her vagina; she exhibits a sudden orgasm expression with her eyes rolled upward, sharply arched eyebrows, and a wide open mouth while her hands grip the viewer's hips with white-knuckled intensity; a first-person POV shot
Clothing: Rebecca is fully naked
