An office lady named Misaki secretly harbored romantic feelings for her boss, Oshima. As their relationship deepened, one day Misaki accidentally discovered Oshima's S&M fetish. Initially confused, Misaki accepted his sexual preferences with the thought 'If it makes you happy,' and was trained through various S&M plays such as bondage, spanking, exhibitionism, and irrumatio. Her dormant masochistic tendencies began to bloom day by day.
