Extremes (1981)

A slim blonde with long wavy hair is reclining on a couch, wearing a black dress, high-angle shot making it look like she’s being filmed from above as things get physical. She’s soon in a bathroom covered in soap suds, moving around in a tub while interacting off-camera — clear close-ups of her wet body and the steam on the walls. Earlier, she’s in a bedroom with a dark-haired guy in a black shirt sitting on the bed beside another woman in a red dress, both slim with short dark hair. Two guys in white robes appear in a doorway scene with the blonde, dim lighting, one with a mustache and sunglasses, the other shirtless and muscular — they’re standing close like they’re setting up for a three-way. Later, a couple is shown kissing intensely in a tight close-up, faces pressed together, hands gripping, moody lighting. The shots switch between wide angles in hallways and tight interior spaces, giving a voyeuristic feel without showing full penetration or specific cumshot details.
