Any Time, Any Play (1990)

The blonde has tight curly hair and a slim frame — you see her first sitting across from a middle-aged guy in an office, but that fades quick when they start making out by the desk. He’s got gray in his short hair, sits back in the chair while she climbs on, riding him slow with the dim lamp light hitting her back. Later they’re joined by a younger dark-haired guy at a bar, same age, same build — the three of them end up in a booth, then against the glass case. She gives a blowjob standing up, face close to the camera, mouth full. Camera stays wide in the office, then tighter in the bar, letting you see the transition from formal to filthy. The lighting shift sells it — from stuffy office to hot bar vibe, her expression changes, more aggressive once they’re in public space.
