Nureta yokujô: Hirake! Chûrippu (1975)

Starts with this slim Asian chick in a floral dress at some movie kiosk, looking all innocent. Then she’s on her hands and knees on a bed, dark hair hanging down, while a buff white guy with short brown hair nails her from behind. He’s got a good grip on her hips, really pulling her back into it. Later, she’s in the backseat of a car, sucking him off with her tits out—red top barely covering anything. The angles are solid, especially when she’s on all fours; you see everything. No fluff, just straight-up fucking and a decent blowjob.
