The Black Devil Omegaverse
They existed to be used by toms.
But even more than that, Hades and all other young toms were taught that no-furs were happy that way. The small, furless beings were born to bear kits and because of that singular purpose, they were also eager to be fucked at any time and by any tom.
There were, of course, stories about that special bond that could happen, the Innehavre bonding. Mostly it was in ridiculous romance novels about toms and these extra special no-furs who had personalities and drives beyond trying to find a good tom to sire kits on them. But even in those fictions, the end was the same. The no-furs wanted to be filled with their tom's seed and give him kits.
