A group of yakuza suddenly appeared in front of my girlfriend and I, who were living happily ever after. According to them, Mai had been held by the yakuza as a form of debt collection and had run away the day before. We were all kidnapped and held captive despite our attempts to leave the place, and we were told that if Mai could endure a week of Kimesek training, we would both be released. I could do nothing but watch while praying for my safety as I desperately endured the mob's brutal training from deep throat to vaginal ejaculation.
