Chaleurs (1971)

This one’s got a bunch of variety packed into it. A slim white brunette with short hair starts off leaning against an old car outdoors, then moves to a bed where she’s lying down in a gray shirt, looking distressed. The action kicks off indoors with her giving a slow, dramatic blowjob to a guy in uniform. The camera gets up close during this part, so you see every detail. Later, they’re outside again, making out against a stone wall before she’s standing in a garden, holding onto a tree branch. The mix of indoor and outdoor scenes keeps things fresh, and the lighting switches between soft artificial light and natural daylight.
