Akane was dating a boyfriend in school but ended up raped by the asshole homeroom teacher.
She ended up developing an addiction and becoming the sex toy for the teacher, with outrageous results.
The original doujin name translates into something like “Introverted Beauty Gets Raped Over and Over by Her Homeroom Teacher”. And this parody is based on the 3rd and last installment of the series. We already got movies based on the previous editions: The first was MUDR-098, and the second was MUDR-125.
All starred by Eimi Fukada, so it was very fitting that she would complete the trilogy in this glorious finale.
Eimi Fukada does it again, lads. A very substantial masterpiece, maybe even one of the best movies this year so far.
