Starring Fuji Kanna, this work kicks off with the shocking premise of Yūta, who loses his job and stays with his brother's family, asking his sister-in-law to take his virginity. Although the unrealistic AV-specific scenario initially felt awkward, Kanna's overwhelming acting skills quickly pulled the story into a realm of believability. Her dramatic reaction—eyes wide open and arching back at the moment of penetration—shared a tingling pleasure with viewers, and she immersed herself perfectly in the role of a lustful sister-in-law who transforms thereafter. Her expressions blending kindness and eros, along with bold sex scenes using her whole body, fully showcased the beauty of her ballet-trained physique—well-shaped bust, slim waist, and fair, beautiful legs—making it a perfect score.

However, as the seventh installment in the series, some voices call for more intense play rather than storyline. Indeed, the artificial and unnatural positions or emphasis on her ballet background can be off-putting, and critiques urging a more thorough pursuit of elements like bondage or whipping hit the mark. While Kanna's acting is stable, with her lewd acts and moans praised as overly erotic, aspects like over-sensitivity or lack of script ingenuity are regrettable. Still, her full-bodied immersion into the role is a standout feature of the series, especially her expressions when the male member enters, which are absolutely unmissable. Overall, it's a hot work worth watching, even for non-fans.
