Raped his best friend Saki Okuda's mother

Saki Okuda is a mother who loves her son dearly. So she couldn't ignore the fact that her son was being bullied by a particular group of students. She went to school and met them but received threats. One day while she was at home cooking, a group of students knocked on her door. They came in large numbers and had an extremely rude attitude. And the ending was that Saki was gang raped without being able to resist by young and strong students.
