Un moment d’égarement (1977)

A fit, dark-haired guy in his 30s fucks a petite brunette in her 20s on a beach at night, surrounded by string lights. They’re fully naked, grinding hard in a standing embrace before switching to a seated position in the sand. The camera catches close-ups of her ass clenched in his hands as they move together slowly, then faster. Later, the same girl sits at a garden patio table in the daylight, drinking tea across from a female friend — both in casual clothes, not touching. There’s no dialogue, but the shift from wild outdoor sex to quiet daytime hangout feels strange and kind of hot. The lighting in the night scenes is soft, showing skin and motion without overexposing.
