Location: late evening in a dimly lit academic office with heavy oak bookshelves, a large mahogany desk, and soft amber light from a desk lamp casting long shadows across the room
Position: Prof. Dr. Hanna von Stein is bent over the desk on all fours, her chest pressed against the dark wood and her hands gripping the edge with white knuckles while a penis penetrates her vagina from behind; her face shows an intense pleasure expression with half-lidded unfocused eyes and a slack open mouth; first-person POV
Clothing: Prof. Dr. Hanna von Stein is wearing a professional grey pencil skirt hiked up to her waist, black silk stockings, and a white button-up blouse that is partially unbuttoned
