The chairman father-in-law orchestrates a marriage for his own selfish desires. He forbids his son from any intimacy for a year, and when the son fails on his wedding night, the father-in-law sends him away on a 5-day business trip to finally claim the daughter-in-law for his own twisted training.










The stepfather's target was me.... Rio Kuriyama. With her pretty face and innocent aura, Rio has really built up an impressive filmography. She has undoubtedly become one of the top actresses in the AV industry. Damn you, Ozawa, for having your way with cute little Rio... how scandalous. Watching her get 'trained' at the whim of her stepfather, her beautiful body shuddering with pleasure is truly erotic. Her moans are great, and watching her face flush and her body jerk with Ozawa's thrusts is intense. Getting oral while on the phone... that was way too hot. As always, this series delivers on the eroticism.
Kuriyama Rio is beautiful, and it features exactly what I was looking for. It felt a bit different from the implication of the title 'One-sided.' It might just be me, but the color grading felt a bit too heavy overall. Still, I think it works in its own way.
Even though it's a two-year-old film, you rarely go wrong with this actress. The premise of her readily giving herself to an old man after just a year of no sex is a bit questionable, but she’s amazing—that flawless waistline without a hint of fat is incredible. This one was good too.
Rio Kuriyama, who plays Rio, is pure innocence in both looks and mannerisms, but the way her expressions change during those training scenes is exquisite. The development after her husband leaves for a business trip is so suspenseful, it really draws you in. The camerawork captures the atmosphere perfectly and makes it feel incredibly immersive. Her voice, especially during the scenes with her father-in-law, blends anguish with that feeling of being unable to resist—it really sticks with you.
Her style, outfit, and makeup are perfect! But Ozawa... he's just too annoying! It's not like it's an arranged marriage or he wants grandkids, so the non-stop creampies are just off-putting. Her blowjob faces and ahegao are erotic, though. Wouldn't hurt to have a facial and some clean-up at least once.
