There's a shift of power happening in Hell, and nothing will ever be the same. Kerr has been with high demon Horatio's household since his age of majority. A natural submissive pleasure demon, for the last seven years he has been untouched by his master Horatio and his job has morphed into a more managerial role. Still, it's a shock when goons from Master Belial's house arrive at his doorstep to inform him he's been sold and his new master expects him to come immediately. Lost by Horatio in a card game, Kerr finds himself in the Belial household, where Ceris, Master of the Harem, takes Kerr under his wing. Kerr is not only honored and used as he was made to be, but he is given a newly acquired demon, Harmony, as his own to train. The three pleasure demons have a rocky start together, but they have all the time in Hell to figure out how to work together and it isn't long before they begin to care for one another. Meanwhile, Belial has waited for thousands of years for Horatio to admit that he's actually a submissive. When it appears that is never going to happen, Belial arranges for his best friend to lose a card game in which he's offered himself as the prize. Horatio can't believe Belial would do this for him, but the council puts their seal of approval on the bet, and he has no choice but to offer himself to Belial, who immediately gets to work convincing Horatio that he'll be so much happier as Belial's sub. Will Kerr and Horatio find joy in their places in the Belial household? Only time will tell.
