Kanon Hara, a new teacher at the school, is spotted secretly meeting with a male student and caught on camera. Days later, she's ambushed in the locker room by a group of men who tear off her school swimsuit and forcefully rape her. When she tries to protect her students in the classroom, she's punished with a brutal titty fuck. As her consciousness wavers, she's bound to a cross and made to climax repeatedly with the "Ultimate Orgasm Machine Drill." She's then subjected to a relentless four-man gangbang with creampie after creampie, an ordeal she'll never forget.
