Onna kyoshi: Yogoreta hokago (1981)

Starts with this slim Asian teacher in a long coat holding a fishing rod like she’s about to hook more than just fish. She’s got that innocent look but you can tell she’s down for whatever. The scene shifts to a bedroom where she’s on her knees sucking dick like she’s been craving it all day. Guy’s got a decent build, nothing crazy, but she’s into it—deep throating, gagging a little, eyes watering. Then it’s doggy style on the bed, her tight ass taking every thrust while he grips her hips. Camera gets right in there, no shaky handheld crap—clear shots of her face when she’s getting pounded. The way she moans, you’d think she’s been waiting for this all week. No weird plot, just straight-up fucking with good angles and a girl who knows how to sell it.
