Zwei Rebläuse auf dem Weg zur Loreley (1975) (Better Quality)

The blonde starts alone, riding a bicycle down a sunlit road, wearing tight clothes that show off her slim frame. Later she’s on a playground swing, facing forward, shorts and a top, moving gently — totally out in the open but not doing anything sexual there. Inside, she’s in a bedroom with a guy in his 30s, both on a bed under dim light from a lamp, going at it face to face. Another woman shows up — redhead, ponytail, also slim — and joins them at a dining table first, then in the bedroom. They end up in a three-way: the guy gets a blowjob from the redhead while the blonde rides him, then they switch positions, lots of skin visible, natural lighting makes the scenes feel raw. The camera stays wide for almost everything, never zooms in close on faces or genitals, keeps all bodies fully in frame.
