A strict czech teacher's secretive desire: an explicit masterpiece

In a dimly lit, empty classroom bathed in natural light, a masterpiece image unfolds. A strict Czech woman, aged between 50 to 55, stands, gasping for air and sweating profusely. Her curvy hourglass body, with a huge rounded butt, is clad in a tight white blouse half-unbuttoned, exposing her perfect, large breasts. Black stockings adorn her long legs that rest on black pumps with anklet straps. Her face, a picture of suffering beauty, is framed by black hair neatly gathered in a single updo bun and her wide open eyes, covered by thick round framed glasses, are fixed intently on the viewer. In the background, a faceless man, fully clothed, thrusts from behind into the woman, who is bent over a desk, arching her back. The man's super massive long stiff erected dick is half inserted into the woman's anal region as he lifts up her skirt, exposing her butt. A puddle of cum leaks out onto the floor below them.
