The plot where Nakata, a dedicated teacher, descends into madness nearing retirement, masterfully portrays the inner turmoil of human nature with exceptional drama. The scene where he discovers Nagisa in a school swimsuit from a student's hidden camera captures the moment when the boundary between normalcy and abnormality collapses. Nagisa's slim yet feminine figure, accentuated by the swimsuit, is visually stunning and naturally leads to Nakata's awakening of a new fetish.

Around the 46-minute mark, the sex scene features a missionary position with the school swimsuit on, culminating in a massive ejaculation that cuts across the swimsuit—a climax that is utterly captivating. For viewers with a fetish for cumming on school swimsuits, this scene alone can trigger multiple rounds of excitement. The combination of a slender body and the swimsuit is perfect, and the depiction of insertion by moving the swimsuit aside without tearing it enhances realism while fostering eroticism.

On the downside, Nagisa's weak, submissive resistance feels somewhat lacking, but overall, the work delves deep into the forbidden teacher-student relationship, exploring the liberation of a middle-aged man's sexual desires. The story intertwining the pivotal life moment of nearing retirement with sexual awakening offers more than just an AV; it can be enjoyed as a human drama. The acting and cinematography are top-notch, fully bringing out the appeal of the school swimsuit fetish.
