Roman-ko Club: Ecchi ga Ippai (1986)

This one’s got a skinny Asian chick with straight black hair down to her shoulders. She’s petite, no body hair, and looks like she’s in her early 20s. The guy’s ripped, shirtless, and fucking her from behind on a bed with white sheets. He’s got a good grip on her hips, and you can see her tits bouncing every time he slams into her. The camera’s at a solid side angle, so you get a clear view of the action—no weird close-ups, just straight-up doggy style. The room’s got a mirror above the bed, so you get a bonus reflection shot. She’s taking it like a champ, and the lighting’s warm, so everything looks clean and sharp. No fluff, just a solid fuck scene with good energy.
