hi, looking for a scene: couple, blonde woman. Man drives her to a motel at night in a Mustang-like car, gives her money and a pistol. She showers, he returns. She opens the door in a towel, holding the gun. Without a word, they have passionate sex in low light/motel room gloom.
I saw it some time ago and can't find it anywhere.
