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 with her legs wrapped tightly around the viewer's waist and her hips thrust upward 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 nails dig into the viewer's skin; a first-person POV shot
Clothing: Rebecca is fully naked
