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

I’m being bullied by the outgoing classmates. Finally, my house has been taken over by the delinquents! My older sister couldn’t bear to see me being bullied at home either, so she spoke up for me, but that only made the delinquents even angrier… My classmates smear my beautiful older sister’s face with their semen and laugh at me. It didn’t end with just one day, they came to my house every day…
