To stop a deranged mom's rampage, a parent lashes out violently, but homeroom teacher Ayane Haruka attempts to intervene calmly—only to be brutally raped in front of the out-of-control mother. Forced into humiliating public exposure on the school grounds, she is assaulted by the parent, filmed against her will, and then blackmailed by the school janitor. Ayane becomes a plaything for the entire school, treated like a mere female toy. Continuous electrostimulation keeps her squirting uncontrollably, driving her into relentless, hellish orgasms. Within the school, she is used as a flesh dildo by the deranged parent and bratty kids, repeatedly subjected to degrading foursomes that shatter her sanity—yet her body continues to squirt without end. After school, gangbangs continue in endless cycles, her pride as a teacher torn to shreds, her identity collapsing. She is forced to take multiple cocks at once, reduced to a cumdumpster until completely broken.
