MKON-001 My strong and kind sister who always protects me is being taken by the DQNs in my class and turned into a cum dump, but I'm too scared to do anything... Saiha Miori

Miori sister who protected me from bullying by DQNs. She is a heroine of justice who has always helped me since childhood. However, Miori's sister has bought the grudge of DQN and others. DQN who rush to Miori's older sister's room in a group. I watch silently. A scream comes from Miori's room, and the creak of the bed. I'm a really useless younger brother who can't protect my precious older sister. Miori, I'm sorry... For the next few days, Miori will be used as a meat urinal by DQNs.
