Popular milf Hikaru Kiuichi endures the strict yet sweet initiation of Girls' Academy, subjected to psychologically destructive teasing—brought repeatedly to the brink of orgasm only to be denied at the last moment. Despite this torment, she experiences climax after climax, each accompanied by involuntary urination and massive squirting. An unprecedented wave of irregular ecstasy gradually drives her insane. Overwhelmed by this extreme pleasure, she eventually degrades into an obsessively devoted sex slave. Finally, surrendering her body to a man's gentle touch, she loses all sense of self in a shocking convergence of ultimate pleasure and total destruction.
