Farewell Scarlet (1975)

One of the brunettes starts off lying on the bed, her long straight hair spread out as the guy leans in. He’s got his hand on her back, and the camera gets up close, showing how slowly he’s moving. The MILF joins in later, blonde and curvy in lingerie, posing while the other two keep going. There’s a lot of eye contact with the camera, especially during the blowjob parts. The lighting is dim but warm, making the blue sheets stand out. The whole scene feels intimate, with the performers taking their time. The oral parts are shot well, with close-ups that don’t miss anything.
