Viols en Cornettes (1983)

A slim brunette with long dark hair is on her knees, sucking a dude with short dark hair in a dim bedroom. You can see the bed, pillows, and how into it she looks — head bobbing, one hand gripping his thigh. She switches to lying on her back, legs up, taking deep thrusts in a rough missionary. The guy’s muscular, moves fast, and she’s moaning loud, nails digging in. Camera stays tight, focusing on faces and the wet oral close-ups. Not much foreplay — just straight fucking and a solid gagging blowjob.
