Slaves to humanity

It has been milleniums since humanity managed to conquer intergalactic travel and with that their technology developed beyond any other race in the universe could comprehend, they've become so powerful no other species of the universe could match them so they began to believe themselves superior to all other live they found, so much that they believe it to be their right to conquer their worlds and add them to the human empire and **** all of their inferior people to become slaves to humanity.

The slaves can be used by anything that their masters may want, from manual labor, to making them perform for entertainment to making them sex pets for pleasure.

The **** races can be of any kind, from a world of furries to a more distinct alien race, the characters used on the rp can be original or from some existing canon setting, just try to keep each setting as a seperate planet.

The story can be told from the perspective of a human **** driver or owner or of one of the enslaved aliens, it can start when a planet is already conquered and the people have already fully transitioned into slaves or during the time of their invasion where some are still trying to put up a futile resistance.

Some humans could also end up enslaved if they end up becoming filthy alien sympathizers and try to liberate them or desert humanity to fight alongside those inferior creatures, since they seem to believe they're like them, they should be treated like them.
