My Sex Slave

At the workplace, Keno and Yumi are coworkers. While Keno holds a higher position as Yumi’s managing director, she tends to ignore his instructions. This greatly angers Keno, as he constantly receives reprimands from his superiors and is dissatisfied with the state of his department. With a strong determination for retaliation, Keno decides to target Yumi, who happens to have a wealthy and attractive partner. After work, Yumi often visits a massage parlor to unwind.
