This work features actresses challenging the 'endurance face' directive, where they must not show expressions or make sounds no matter how many times they climax, showcasing their passionate performances. Particularly, Sawai Maho's acting is outstanding; her ability to keep a straight face even as her body reacts draws viewers into the depth of sexuality. Her wide-eyed expressions and trembling body while enduring are captivating. Her climax faces while looking directly at the camera are superb, and the incontinence scene is highly realistic. However, some feel the screaming parts are too short and wish they were longer. Co-star Jurin Remon exudes a latent sexiness with her disheveled appearance, and many fans are excited by her endurance face. Yet, with many close-up shots of faces, it might be hard to watch if the actresses' looks aren't to one's taste. Overall, the expressions upon release after forced endurance are a must-see, and there are high hopes for a sequel.
