Cugine Mie (1978)

A slim brunette with short brown hair and a blonde in her 20s start off sitting on a rock in what looks like a garden or park, talking casually in natural daylight. They’re both wearing casual clothes — sweatshirt, light layers — and the vibe is low-key, almost like you’re watching real cousins hang out. The scene shifts indoors to a dimly lit room with a desk chair, where the guy in his 20s appears in a brief moment, shirtless, maybe part of a different scene or flashback. Then it’s back to the girls, now in an office or home interior, standing close, going from talking to touching. You don’t see full penetration or hardcore stuff in the frames provided, but there’s clear tension building — lingering eye contact, hands on hips, the kind of slow lead-in that suggests they know where this is going. Camera work is wide-shot for setup, then close-ups on faces, focusing on reactions more than action.
