MKON-138 A serious girlfriend I was in a committed relationship with was taken by a playboy, and it turned out she had always had a strong obsession with men. Kojima Miko

Miko and Yoshio, who had been maintaining a wholesome relationship, are photographed by Saito while exchanging a condom and kissing on the way home from a date. Saito blackmails Miko and pushes things further, eventually leading to protected sex. Miko becomes completely drawn in and starts begging for unprotected sex herself, yet she still does not break up with Yoshio. She keeps saying she still loves Yoshio, but in reality she only wants to indulge in the thrill and pleasure of an illicit affair. She also sees Saito as nothing more than someone who can give her pleasure.
