Mari was engaging in compensated dating to earn extra money when Ishibashi, a man recently laid off and drowning in despair, accepted her offer. However, after a certain incident, Ishibashi becomes enraged and captures Mari, imprisoning her against her will. Driven by self-destructive rage, he turns her into his personal sex toy, then brings in acquaintances to use her as well, gathering accomplices to form a gang that takes turns filling her with creampie after creampie. Defenseless and trapped, Mari is repeatedly violated until their cum drains her completely, enduring the harsh reality that no one will come to save her.
