Location: a dim bedroom with white linen sheets and dark wooden bedside tables, where warm amber lamplight casts soft, flickering shadows and highlights the moisture on the skin
Position: Rin is on her stomach on the bed, arching her back with her hips raised and hands gripping the edge of the mattress as a penis penetrates her anus from behind; her face shows a rising pleasure expression with fluttering eyelids, raised inner eyebrows, and an open mouth; a three-quarter shot
Clothing: Rin is fully naked
