DASS-149 Helplessly watching his girlfriend being raped by a gangster

A group of yakuza suddenly appeared in front of me and my girlfriend, who were living happily ever after. According to them, Mai was held by the yakuza as a form of debt collection and had fled the previous day. We were all kidnapped and detained even though we tried to leave, 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 crowd's brutal training from deep throat to vaginal squirting.
