Ecstasy (1989)

One of the girls has curly blonde hair and red heels, standing by a window looking out with her bare ass visible in the low light. The other is sitting on the bed topless, leaning back with her tits out, then they meet in the middle for face-to-face grinding in a dark room. You see close-ups of their cunts rubbing together, slow pussy-to-pussy contact with fingers pulling lips open. Later, one walks down an arched hallway in a tight red dress and purple gloves, looking over her shoulder like she’s being followed or teased. The lighting stays dim throughout — lamp glow, shadowy walls, no bright spots — gives it a voyeur feel. Camera stays at medium distance for most two-shots, then drops low when the girl walks the wooden floor, emphasizing her legs and bare feet in heels.
