Liaisons coupables (1987)

Starts with a blonde bride in a full wedding dress making out with a guy in a suit at a fancy dinner table. Then it moves to a dimly lit room where she’s on her knees giving a hard blowjob in lingerie. Another scene has her outside by a car, still in a tank top and shorts, sucking cock in broad daylight. There’s a group scene with two guys and two girls — one’s a brunette MILF, the other a blonde slut in a dress and hat. They pass each other around, trading oral and teasing. The lighting’s warm, the outfits are classy, and the action is smooth.
