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 with intense muscle contractions as a penis penetrates her vagina; she exhibits a sustained orgasm expression with her eyes tightly closed, pinched eyebrows, and her mouth open in a primal cry while her nails dig into the viewer's back; a first-person POV shot
Clothing: Rebecca is fully naked
