DQN, who bullied me, took over my house and raped me for a week! Watching the seemingly plain but secretly large-breasted older sister be gang-raped in my place in a 4P, degenerating into a wicked state, the scumbag got an erection. (Kujii Tamao SORA-624)

I was bullied by the sunny kids in my class. Finally, my house was taken over by the DQNs!! Seeing me being bullied even at home, my older sister spoke up for me, but that only angered the DQNs… My classmates were playing with my H-cup busty older sister's breasts, using them as masturbation toys. It didn't end in just one day; they came every day, turning my house into a gathering place. I became emotional, a mixture of anger and jealousy… and then, I got an erection. Ah, I'm the worst guy, aren't I!
