With her husband away, Kotone finds herself living with her divorced sister-in-law, Natsumi. Alone in the house, Natsumi hears Kotone's moans one night and becomes obsessed. The atmosphere between them shifts, leading to a forbidden desire.




















It's a great work that hits all the right spots, like the kissing, finger play, and the caressing on the table with only her chest and crotch exposed. The scene where she gets touched while on the phone with her husband is also very erotic.
Sena Ryo's M-tendencies in the previous work were unmatched and her beauty was top-notch, so Amamiya feels a bit lacking in terms of acting by comparison. However, the story is solid and the process of her downfall is well-written. Horiguchi is a total proโher acting, climax performance, and beautiful body are worthy of high praise. I really hope they turn this into a series.
The content is way too soft to be called 'training' (chokyo). The torment isn't hard either; the tools are just a vibrator and a dildo. They do perform lesbian scenes properly, so those who prefer soft stuff might like it. However, since it was titled 'Training,' it was a disappointing watch for me as I was expecting more sadistic torment.
Whether it's the actress or the direction, Kotone Amamiya's performance is superb. At first, she shows strong rejection toward lesbianism and incest. Unlike most works in this genre, it follows a realistic path and doesn't jump straight into the erotic stuff. Until the middle, she resists while being pursued by Horiguchi, but the way her body naturally opens up even while she's tensing up makes you go 'Oh?', and the direction of her gradually relaxing, smiling, and accepting her stepsister toward the end is brilliant. Horiguchi is also perfectly cast as the pursuing stepsister. I don't dislike lesbian films that jump straight into intense action, but honestly, there are too many of those, so I think works that prioritize drama like this are valuable. The ending is a matter of taste, but I think this is a high-level work for an incest-lesbian film.
I don't think training-style lesbian content always has to equal strap-ons. The flow of Horiguchi-san corrupting Amamiya-san into a lewd state was worth watching. However, it's a pity that Amamiya-san was the one being dominated until the end... If Yuno Hoshi had played Amamiya-san's role!! It would have been much more intense, lewd, and worth watching.
