Just the other day, I got married to my student Kaori's father. Kaori, who became my stepdaughter, accepted me, and we were living happily as a family. One day, I invited some male students, who often came to hang out, to my house, but it was a despicable trap to humiliate me...!! I desperately called out to Kaori for help, but she just "smiled and watched" me being violated. And from that day on, I started being gang-raped by my daughter's classmates...
