Jokosei Nise Nikki (1981)

Starts with four skinny Asian girls in casual clothes taking turns blowing a dude in what looks like a nightclub booth. Low lighting, neon signs, and bottles everywhere—feels like a real hookup spot. One girl with long wavy hair keeps licking his balls while another deep-throats him, no gagging. Later, a tattooed brunette with a tight ass gets pounded from behind in a marble bathroom. She’s got a small waist and big tits that bounce every time he slams into her. Mirror’s right there so you see everything twice. Guy’s got a decent dick and knows how to use it—no awkward pauses, just steady thrusting. Last part’s a solo Asian chick in a robe teasing herself on a low wooden table, looks like a Japanese apartment.
