[FSDSS-586] A president who repeatedly ejaculates unstable ejaculation due to reverse power harassment from a beautiful big-breasted secretary who envys everyone...

This narrative details the transformation of the relationship between new secretary Yuko Ono and her company president from a typical boss-subordinate dynamic into a deeply disturbing BDSM (Bondage, Discipline, Sadism, Masochism) relationship.

In the beginning, office gossip hints at Yuko being the president's mistress. The president initially displays strong patriarchal and controlling tendencies, canceling Yuko's plans and demanding her time for dinner. During dinner, he makes suggestive remarks and inappropriate advances, attempting to assert dominance.

However, upon arriving at the hotel, the dynamic shifts. Yuko, with a cold smile, exposes the president's arrogance and begins a process of mental and physical humiliation and conditioning. She orders him to lie down, sits on his face, forces him to beg to see her private parts, and mocks his embarrassment. Through self-stimulation and verbal taunts, she makes the president writhe in desire. Yuko demonstrates absolute control over his body and urges, preventing him from ejaculating until her own climax and commanding him where to ejaculate. The president is thoroughly subdued and becomes obedient.

The next day, Yuko learns the president is married and has no intention of divorcing. She proactively books the same hotel, confronting him about his hypocritical marriage and further solidifying her control over him. Their BDSM games deepen, with Yuko's humiliation and sexual exploitation of the president becoming more explicit, including forcing him to drink her saliva, lick her body, and engage in sexual acts in various humiliating positions.

The relationship even extends to the office. After colleagues leave, Yuko continues to humiliate and engage in sexual acts with the president at his desk, forcing him to lick her feet, control his ejaculation, and then mocking him. Even as colleagues suspect their relationship, they remain unabashed.

The story concludes by suggesting the president is entirely consumed by this illicit and controlled relationship, his suppressed desires fully ignited. Yuko Ono successfully transforms the president from a dominant figure into her sexual slave, with the concluding thought of "e;Mrs. Ono"e; hinting at her triumph in fully dominating him.
