After club activities, three high school girls chat and laugh together. As they exchange stories about love and sex, curiosity arises about whether choking during sex really feels good—prompting them to try it out for themselves. At first, they lightly choke each other, covering mouths and inducing unconsciousness for fun. But soon, they become aroused by the pleasure of being choked and the sight of rolling eyes and convulsing bodies, driving them into increasingly intense acts. Taking turns, they stimulate the unconscious girl sexually while reveling in her reactions, escalating into a shocking three-way lesbian choking session. Their minds unravel completely as they plunge into a hedonistic frenzy, repeatedly fainting and seizing in a cycle of pleasure and oblivion.
