After actually watching this work, it depicts the intense struggle of the skilled investigator Amamiya Nagisa, who undertakes an undercover operation to expose the evil deeds of the Onijima Society, and the content is truly shocking. In the first half, her performance shines as she is restrained in a sailor uniform, resisting but gradually unable to fight against the pleasure. The moment her dignified body reveals a lewd expression is filled with forbidden charm. In the latter half, the scene unfolds where she is stripped naked, with her beautiful clean-shaven pubic area fully exposed to toy torture. The way she suffers in the narrow gap of sorrow yet is led to climax through the torment of electric massagers and vibrators is highly engaging. However, it's a pity that in the crucial climax scenes, the electric massagers and male hands become obstructive, making it hard to see her beautiful bust and armpits. Without this issue, it would have deserved a flawless five-star rating, but the interfering elements cause a sharp drop in evaluation. Overall, while the story follows the typical baby-genre formula and is somewhat monotonous, the actress's acting skills elevate the work, and the depiction of her descent into pleasure is excellent. I look forward to future works addressing these improvements.
