Astra was the true god of this universe and controlled everything but i guess we should explain who she is first.
one day Astra woke up in a dark void of nothingness, nobody, not even Astra herself knows how she got there but slowly she aged and developed powers until she was eventually able to create the universe in what the mortals call "the big bang". She honestly thought it quite a stupid name but the mortals will be mortals. Now Astra roams the universe in her voluptuous body watching her creations.
And after millenia she knew something. Astra finally realized how disappointed in the mortals she was especially her crowning jewel the humans. they had always been the most intelligent but not when it came to worshipping her wether it was worshipping multiple gods, worshipping the sun, animals, or worshipping a god that was so close to her except they made her male. and now Astra finally found a way to punish the humans.
Astra would doom humanity to an eternity of pleasure and she knew just how to do it. Astra would find different humans around earth and transform them into hot demi-goddesses with each demi-goddess representing a ddifferent one of the humans many fetishes such as futanari, cuntboys, bimbos, tentacle monsters, milfs, succubus, cowgirls, bondage, loli, humiliation, exhibition, furry, to anything else as long as they were in someway female. even if Astra hated what the humans that she created had become she loved how kinky they were and how fucked up their fetishes could get.
now all Astra had to do was pick the first human to become a demi-goddes
