"Maso girl, I'll make you feel good by hurting you more." Ryo, a sales manager at a certain company, is stressed from excessive expectations, overwork, and marital issues. Additionally, she was troubled by her relationship with her incompetent subordinate, Haneda. One day, after being attacked by Haneda while drunk, Ryo's masochistic tendencies were discovered. Haneda then summoned Ryo to an SM hotel during lunch break, using wax and whips to inflict pain, and a brutal cock to induce pleasure, transforming her into a lewd bitch unthinkable in the workplace.
