The protagonist, a straight-laced CEO whose family's company is in decline, ends up signing a contract at a bar run by demons—and summons two devilishly handsome young demons to help turn his business around. Determined to save the company, he reluctantly decides to have physical relations with the male demons… only to find himself ravished, body and soul, on the very first night.

Upset and in shock over this, his first time with the same sex, he soon notices that the demons have matured overnight into full-grown "men". There is no turning his back in the face of the pressure they exert and the desire they exude.

To his chagrin, whether on a casual outing or at an important business meeting, the demons constantly crave his attention, completely disregarding time, place, or context.

As his mind screams "No!", his body begins to betray him. While the demons plead for his attention at first, before long he finds himself constantly in heat, desperate to be penetrated, and completely losing control in their presence. The demons, no longer easily fooled like they once were, now demand proper submission and training before they’ll even consider touching him.

Eventually, he surrenders what’s left of his sanity and appoints the demons as his personal assistants—so his desires can be satisfied anytime, anywhere.
…At least the company is doing better now.
