A 34-year-old husband, married for 7 years, always felt something was missing in bed. One day, he spots the handsome guy from upstairs leaving his apartment. Ever since then, his wife's moves have changed completely. What the hell is going on?










*It would be a shame if my glasses were fixed during sex. I was surprised at the transformation of my wife. Getting better at something isn't just a matter of "gradually". The story of how she had a physical relationship with the man upstairs and how he teaches her about pleasure is cut out, so we can see the wife's transformation in an instant. It can be said that the main focus of his life is not with his wife, who is being taught the pleasures of sex and who is changing, but with the wife after she has been transformed.
The 'netorare' aspect of discovering how the wife becomes increasingly lewd through other men was good. If I had to be greedy, I would have liked to see one more stage of her degradation. I also wish the final scene where she begs with a toy hadn't just been left to the imagination.
The title says she gradually gets better at sex, but it wasn't gradual—she went from a 'dead fish' to suddenly being aggressive. The story is quite solid and Yui Hatano's acting was good. However, the erotic scenes felt a bit lacking. By the way, while she's being cuckolded, the camera cuts to the husband actor way too often. Couldn't they reduce that? Or just use a picture-in-picture (PIP) instead?
