Die Frau vom heißen Fluss (1978)
A slim blonde with long hair and a flower tucked behind her ear is lying on a bed in a dark bedroom, barely lit. She’s the main girl in this scene, and she’s all over the guy — first riding him facing forward, slow and steady, then flipping to doggy for harder fucking. The guy’s got a muscular build, brown hair, looks like he’s in his 30s. Camera stays wide during the creampie, showing her back arch as he pulls out and blasts cum across her ass and lower back. Earlier shots show her in a forest and market, but the bulk is bedroom sex with natural, gritty lighting. Not much talking — just focused, physical sex with good close-ups when it counts.
