Keung gaan 2: Chai fook yau wak (1998)

Starts with the blonde in a striped beanie holding a birthday cake—candles lit, tits out. The Asian dude grabs her first, bends her over the couch, and fucks her doggy while the Black guy watches, stroking himself. Switch happens fast: Black dude takes over, slams her from behind, then pulls out and feeds her his cock while the Asian guy kneels behind her, eating her out. They flip her onto her back, both dicks in her face—she alternates sucking them, gagging a little on the Black guy’s thickness. Camera gets tight on her face when they double-penetrate her, one in her pussy, one in her ass. Lighting’s dim but you see every grimace and bead of sweat. No fluff, just raw, back-to-back fucking with zero downtime.
