Frisky Business (1984)

Starts with a blonde and a brunette taking turns on some guy’s dick outside—towel on the beach, POV shot, close-up so you see every detail. Then it moves inside to a bed with wooden walls, and the brunette’s got this curvy figure in white lace lingerie while she gets her pussy eaten. Later, there’s a doorway scene where they’re all over each other, kissing and groping. Ends with the guy going down on one of them on a bed, hands on her thighs. Both girls are slim, one’s got big tits, the other’s more average. Decent lighting, natural and soft, so you never miss the action.
