Reiko, caught in an affair, becomes her son's sex slave after being blackmailed. Even after losing her job, her body craves the pleasure she was trained to enjoy.




















The 40-minute segment where she gets fired for refusing the boss is unnecessary. The 18-minute masturbation scene is worth watching. She sneaks into her sleeping son's room at night, takes off his pants, and performs oral sex on his erect penis. She rubs herself against his face while still wearing her panties; when he wakes up and tries to kick her out, she forces herself on him. She strips him and continues. He resists, citing their mother-son relationship, but she claims her husband's long-distance assignment has left her sexually frustrated and losing her mind. He reluctantly gives in. She performs cunnilingus on her while she's on all fours, then flips her over to continue. She performs oral sex on him while he's on his knees, then rides him. She switches to reverse cowgirl, leaning back on her hands. The dirty talk, starting with 'fuck me,' is incredibly erotic. He thrusts away in missionary, ejaculates on her cheek, and she finishes him off with oral.
I wanted to see Shimura Reiko's massive backside after a long time and rented this expecting the kind of plot the title suggests, but I was completely scammed. For starters, it doesn't even reach the level of a 'human toilet.' A mother turns into a nymphomaniac, begs her son, gets rejected once, and then they just have normal sex and it ends. Based on the premise, it feels like it only covered the prologue. The 'aftermath' should have been the main focus, but it's completely absent. The interaction with the boss is too long, and the scenes of the son giving a massage or drinking are unnecessary. If it were me—or rather, normally—you'd wrap that up in 15 minutes and spend the rest of the time deeply depicting the lewd daily life of a masochistic mother who has fallen into being her son's 'human toilet' and the sadistic son who reigns as a tyrant. That's how it should be. Does no one notice the gap between the title and the content? Do they not find it strange? It's baffling. Well, the incompetence of the creators is nothing new, so I'm not even surprised anymore. I'm only giving this rating for the actress's sake.
The characters involved are her boss and her own son. About 60% of the work focuses on her being trained and becoming lewd through her interactions with the boss. The second half involves her son; a drunken Reiko, craving sex, sneaks into her sleeping son's room and starts pleasuring him. At first, the son gets angry and kicks her out. However, she comes back in, shouting, 'Mommy is so horny, I need your cock,' and attacks him. Between her handjobs, deep kissing, and nipple play, the son eventually gives in. It's a bit of a turn-off that she uses a condom despite being so wild and aggressive with her son. Overall, it was a pretty solid production.
