(Inspired by the Elven Overlords futadom Captions (obviously)
Elves, mythical beings once thought to be nothing more then myth, that was in tell they invaded the earth. From a world of magic they called Avalon, the Elves came, first taking individual people. But then, on that fateful day so long ago, the Invasion finally became an actual invasion.
They started with capitals, and big cities, taking them over quickly and all of the worlds governments, and the ports, and factories, and all of society, fell. Many tried to use the worlds weapons, the guns and the bombs, but even the mightiest of weapons, did nothing against the elves magic. It turned nature against us, though many would say it was fitting seeing what we did to it.
The Elves had a third gender that ruled over all, the futa. These big dicked women had cum that "Bound" any man or woman whom were forced to drink it, or had it fucked into them. This Bound people were the the slaves to the futa, not just humans but even their own elven kind. The human race is destined to become the slaves of the Elves, a fate made better by the Elves cum restoring youth, extending life.
And worse by how varied the treatment of the Elves slaves can be. With some treated as the slaves they were, while others were considered to almost be equals to not only the Elves, but even the Futa of their race.
