Teacher Yurika finds herself targeted by a group of fearless, unruly students. Her home is invaded and she is gang-raped, but the students aren't satisfied with just that—they move in and start living there as if it were their own, freely doing as they please. Forced to serve and entertain them, Yurika is continually subjected to their sexual demands. Despite her initial resistance, she gradually begins to derive pleasure from the relentless abuse.
