Seiko no futomomo: Zoom Up (1982)

Starts with Seiko kneeling in a dim basement, arms crossed like she’s tied up. She’s got that skinny Asian teen look—long loose hair, collarbone sticking out, tiny tits but thick thighs that pop when she spreads her legs later. Next scene jumps to some office roleplay where she’s in a short bob wig and glasses, flipping through papers before dropping to her knees. The camera zooms in tight on her mouth when she goes down on the guy—you see every slurp and her lips stretching around his shaft. She’s not just bobbing her head; she’s using her tongue on the underside and gagging a little when he pushes deep. Last shot is her riding him reverse cowgirl, tits bouncing while she plays with her clit—good angle on her ass and his dick sliding in and out.
