J-cup female teacher Azusa Ayano, known for her tall, striking figure, endures a series of tragedies. Caught smoking in the restroom by students, she pleads to keep her job by saying she'll do "anything," but the men exploit her words, blackmailing her into putting semen-covered cigarettes in her mouth and forcing her to masturbate. This degrading act distorts her beautiful face and escalates into a brutal threesome. Returning to the classroom with a gloomy expression, she begins her lesson, only for the students present to suddenly pull out their dicks, turning the class into a bizarre "dick lecture." In this twisted classroom, she suffers 20 consecutive creampie assaults, her body completely defiled.
