Shinderera Ekusutashii: Kuroi Hitomi no Yūwaku (1988)

Starts in some kind of nightclub or bar with neon lights everywhere. The guy’s got a sleeve tattoo and a decent build, holding this slim brunette with long hair up on a counter. She’s got full lips and a tattoo low on her back — you see it when he flips her over. They’re going at it standing up, her legs wrapped around him, then he carries her to a bed and nails her doggy style. The camera gets right behind him so you see everything. Later, she’s alone with a big green dildo, looking like she’s about to wreck herself with it. Ends with her in lingerie on the bed, playing with a vibe and giving the camera that ‘come fuck me’ look. Lighting’s dim but you get a good view of everything — no shaky cam, just solid angles.
