The bold temptation of the excessively beautiful and carnivorous sister-in-law is a masterpiece that vividly depicts forbidden and immoral acts. The pleasure of being cleansed and the unique atmosphere created by the Showa-era-style house set are captivating. Hana Saki Ian's charm lies not only in her beauty and soft body but particularly in the daring temptation scenes in the bathroom that are especially impressive. Being enamored by her skilled lead while feeling an uncontainable thrill is irresistible. The multiple kisses and continuous cowgirl positions naturally draw the viewers in. However, the story development feels somewhat monotonous, and opinions may vary on the length of the bathhouse scenes, yet the overall eroticism and allure warrant high praise. Ultimately, Hana Saki Ian's presence is overwhelmingly wonderful and significantly boosts the ratings. Personally, I would like to give it four stars, but as a fan genuinely wishing for her return, my expectations are boundless!
