To Haruna Kato, who trains daily, Ai Morishita taunts, "You're training because you lack technique, right?" Haruna fires back, "I never lose to someone who doesn't train," sparking a lesbian bout in the ring. Gradually overwhelmed by Morishita's superior skills, Kato is made to climax helplessly and suffers a humiliating defeat. Afterwards, bound with her hands tied while wearing only a swimsuit, she's left completely immobilized, forced to endure further degrading orgasms. Fueled by a desire for revenge, Kato challenges Morishita to a rematch. Whether her revenge succeeds—and whether she can make Morishita climax—remains to be seen.
