Das Sex-Abitur (1978)

A curvy blonde in her 20s stands barefoot in a living room, wearing nothing, her long hair hanging down as she reaches up to a high shelf. The bookshelf takes up most of the wall, and there’s a cheetah standing calmly behind her, its head near her hip. They’re both in frame together, still, like it’s a posed scene—no action between them, just the contrast of her pale skin and the animal’s spotted coat. Earlier shots show two couples in different rooms: one pair, a slim brunette and a muscular guy with a mustache, having sex on a rug under dim light, bookshelf and glass table visible. Another scene is a naked conversation in a bedroom—older guy with glasses, gray hair, talking to a slim young brunette on a bed. Then a third scene shows three people in a doorway: a clothed man, a clothed woman, and a naked blonde talking to them, bookshelf and lamp in the background. No interaction with the cheetah, no sex with the animal—just the girl, the shelf, the cat, and the mood.
