After finding a condom in her son's room, a mother is overcome by a sudden, intense carnal urge. As she indulges in masturbation, her son walks in, instantly captivated by her ripe, pale curves. He decides to cross the line, and she, despite her initial shock, finds herself trembling with forbidden pleasure as they lose themselves in a raw, intimate encounter.




















Beyond her flawless skin, the shape of her butt and its smoothness—which just begs to be touched—are incredible. She’s good at dirty talk, and she really climaxes during the doggy style scenes.
I watched an Oishi Shinobu work for the first time in a while! Man, I'm totally defeated! I surrendered before I even got to see her bare ass. Even without seeing it bare, just her butt in panties is more than enough. I don't know how many times I've had to surrender just watching this one video.
As a fan of Yanoguchi's work, this ranks as a masterpiece. It would have been perfect if not for the kitchen scene. I think the masturbation scene could have been cut—not sure who that's for. Oishi-san's cuteness is top-tier even among mature actresses. It's a shame she didn't do more work, as there aren't many actresses who can follow in her footsteps.
*Anyway, Shinobu's butt is amazing! In all scenes, the butt is the main angle. Masturbation, blow job, and karami were all good!
It's exactly as the title says—all about the butt. For an hour and a half, there's nothing to see but that. For a solo feature with Shinobu Oishi, the scenario is lacking; it would have been better as an omnibus.
