Marcia trionfale (1976)

Blonde milf with curly hair and a slim frame is on her back under a blanket in a dark bedroom. A guy in a military-style uniform stands over her, pulling her around by the hips. They go at it in doggy style, deep and rough, her ass jiggling with each thrust. She takes it face-down, then flips to her back for a sloppy blowjob where he jerks off into her mouth. Later, there’s outdoor footage of a courtyard in daylight, and other scenes with men in uniforms in what looks like an office or rec room—maybe flashbacks or different parts of the story. The sex is raw, not too much talking, just steady fucking with decent camera angles on the action.
