Die Masche mit dem Schlitz (1980)

All three girls are young, slim, and fully nude, sitting and lying on a living room rug in a dimly lit room. They’re not doing hardcore sex, but there’s a lot of casual nudity and light physical contact—arms over shoulders, hands brushing against thighs, one girl leaning into another with her palm near a breast. Two of them have short hair, the third has longer blonde hair and shifts positions often, rolling slightly and exposing more as they shift. The camera stays wide, capturing the whole group without cutting to close-ups, which keeps it more about the vibe than explicit action. The setting looks lived-in, not staged—couch nearby, low lighting, no fancy production. It feels spontaneous, like something real people would do after a few drinks.
