Nove ospiti per un delitto (1977)

A slim blonde woman with curly hair stands in a sunlit living room early on, wearing a black robe that she later drops for a scene with a mature guy in low light. They’re in a dimly lit indoor setup with lanterns, going at it face to face — he’s older, gray-haired, wiry but into it, and she’s riding him slow before switching to doggy. Later, outside on rocky terrain, another older guy appears, brown-haired with wrinkles, walking around like he’s part of some strange plot. The lighting shifts between natural outdoor shots and moody interior scenes with close-ups on faces during penetration. Camera stays tight during the sex, especially on the oral parts — she gives head kneeling on the floor, mouth full, eyes closed. Not much movement between locations, but the contrast between her smooth body and the rough middle-aged dudes adds a weird edge.
