SORA-625 The DQN who bullies me has taken over my house and is raping me for a week! My beautiful older sister, who I'm so proud of, is gang-raped in a 4P gangbang as a substitute, and I get a boner watching her climax Natsuki Takeuchi

I'm being bullied by the more outgoing students in my class. Finally, my house has been taken over by the delinquents!! Unable to bear seeing me being bullied even at home, my older sister spoke up for me, but this only made the delinquents even more angry... My classmates sprayed their semen all over my beautiful older sister's face and laughed at me. It didn't end with just one day, they came every day and made my house their hangout spot. I felt a complicated mix of anger and jealousy... and then I got an erection. Ah, I'm the worst kind of guy!
