HUBLK-050 Big brother, I'm sorry it's come to this... I'm sorry... My little sister being bullied at school and the strong incestuous rape of her brother ~The Madness in the Classroom~

A sister targeted by school bullying, subjected to severe bullying every day. The bullies, tired of ordinary bullying, summon the brother of the bullied girl, making him a target as well! The brother, who should have protected his sister, watches her being sexually harassed but is too scared to do anything. He himself also experiences sexual harassment and has an unfortunate erection in front of his sister. It's a hellish world with no gods or buddhas. The brother and sister fall into this world and become objects of ridicule and torment. The brother's pride and the sister's self-respect crumble. The intense bullying by these sadistic students, crossing lines that should never be crossed, has unimaginable destructive power!
