This work features a story where Karen, a newlywed OL trying to conceive, is trapped in a密室 shared room during a business trip with her superior Tabuchi, loses her rationality due to aphrodisiacs, and undergoes humiliating experiences that lead to her becoming lewd. The beginning starts with a scene of a reluctant Karen being violated naked, creating a tense atmosphere that draws viewers in. However, as the story progresses, nude scenes decrease, such as her wearing stockings or not removing her bra, which feels somewhat lacking. Karen's body appears more toned than before, showing growth that is a positive aspect. The hotel setting is luxurious, with realistic developments like drugging drinks, and the continuous creampie on the sofa and oral sex in the bathroom are impactful. The phone scene, where she nearly gets caught by her husband, adds suspense, and the morning lewdification using drugs and a vibrator is sensual. The male actor being older results in monotonous positions lacking variety, which is a downside. Overall, the strong NTR elements and extreme sexual harassment depictions unique to fiction are enjoyable, but the lack of scene variety is disappointing. Recommended for fans.
