Atame! (1989)

She’s got long blonde hair, slim build, small tits, and she’s all over this dude in the kitchen. He’s got short dark hair, lean fit build, clean look — seems like a real young couple fucking around at home. They start in the bathroom with her giving a handjob against the sink, jeans halfway down, then move to the kitchen where she rides him on a chair, up and down slow, grinding hard. Camera stays tight, no cuts, you see her bounce and then switch to doggy against the counter, ass high, back curved. Later they’re face to face on the floor, missionary style, deep fucking, lots of skin contact. What stands out is how casual it feels — no porn lights, just natural shots through sheer curtains, plants in the background, clothes in the closet. You even see an older guy briefly in a different room, sitting, maybe setting up the camera? Doesn’t interact, just there.
