La Villa (1974)

This one starts with a slim, fair-skinned brunette in her 20s posing in a bathtub, holding a glass like she’s waiting for someone to join. The mood is soft, dim, and kind of intimate, especially when the bearded guy in his 30s starts kissing her neck in the water. He lifts her up in a hug, and she wraps her legs around him — it’s a smooth transition to fucking while standing, and the camera stays close enough to feel like you’re right there. There’s a lot of natural light in the other shots, like when she’s tilting her head back with her mouth open, looking ready for more. The close-ups on her buttocks are sharp, and the whole vibe is relaxed but hot. No crazy acrobatics, just solid, personal-feeling action.
