A visual novel comes to life as a group of Japanese schoolgirls, unaware of the dark fate awaiting them, gather in an empty classroom. Their teacher, a sadistic master, silently observes as they chatter and giggle, innocent of the impending storm. Suddenly, he springs into action, binding their wrists and ankles with expert precision. The girls squirm and protest, but their futile struggles only serve to heighten their teacher's arousal. He orders them to strip, revealing their young, perky bodies, and begins a brutal, non-consensual fucking, using their holes interchangeably, leaving them a sobbing, used mess.
