Everyday at school, Akari-chan is subjected to harassment and being ignored. Being a gentle and weak girl who couldn't voice her opinions, she was being bullied at school. It was her homeroom teacher who saved her. After that, the bullying stopped abruptly, but in return, Akari-chan became completely submissive to the teacher, even being treated as a sexual slave. She's afraid of going back to those days of being bullied, but she's also scared of getting pregnant because the teacher always ejaculates inside her... Unable to refuse, Akari-chan continues to fall deeper into the abyss without being saved.
