Chikan ryôin chikatetsu (1975)

This one’s all about an older Asian MILF with dark hair and a slim build. She starts off talking to the guy in a room with traditional Japanese decor. Things move to the bedroom, where they get cozy on a bed with yellow blankets. No hardcore action here, but the intimate vibe is strong. The camera keeps it soft and natural, focusing on their connection more than anything explicit. The guy watches her from the garden at one point, adding a voyeuristic twist. A chill, slow-burn kind of scene.
