Manicures a Domicílio (1978)

A slim Asian girl with long dark hair is front and center here, first seen running through an apartment, then making out with a younger Asian guy in a dim room. They’re fully clothed at first but things move fast — she drops to her knees and takes his cock deep, no hesitation, going slow with her mouth while using her hand. The lighting stays low, almost moody, but the close-ups are sharp enough to see every suck and swallow. Later, they switch to missionary with her on her back, legs up, getting pounded hard while she moans quietly. The whole thing has a voyeuristic vibe, like you’re watching something private. Nothing wild or acrobatic, just intimate, steady fucking with real-looking chemistry.
