Hanra honban: Joshidaisei bôkô-hen (1990)

Starts with the two Asian girls—both skinny, long dark hair, one with a little more curve to her ass—making out on the bed while the black dude watches. They take turns sucking his dick, slow at first, then one of them deep-throats him while the other plays with his balls. Switch to doggy style, and the camera gets right behind her so you see everything—her tight pussy stretching around his thick cock. The other girl isn’t just sitting there; she’s kissing him, jerking him off when he’s not fucking her friend. Later, they flip to missionary, and the second girl climbs on top for a solid riding session. The lighting’s dim but you still get a clear look at the action. No awkward pauses, just steady fucking with good close-ups on the oral and penetration parts.
