Wananaki (1975)

This one’s got a solid threesome scene with two Asian girls and one guy. One girl’s got long dark hair, the other girl’s hair is also dark but a bit shorter. The guy’s got short dark hair and a slim build. They start with some intimate embracing on a red couch, then things get more intense with oral and doggy style action. One girl gives the guy a blowjob while the other girl watches and eventually joins in. The camera’s mostly close-up, giving a good view of their facial expressions and body language.
