Nômitsu zetsugi: Mekuri ageru (1996)

Starts with the guy already behind her, doggy on a white-sheet bed. She’s got long wavy auburn hair, freckles on her shoulders, and a slim but curvy body—tits aren’t huge but they bounce nice when he slams into her. The angle’s side-on so you see his dick stretching her out every time he pulls back. After a few minutes they switch to making out on the edge of the bed; she drops to her knees and starts sucking him while looking up with dark lipstick smeared. The lighting’s dim, just a bedside lamp, so it feels like a late-night hookup. No crazy positions, just solid fucking with good close-ups on her face when she’s gagging on it.
