you don't need to ask to erase all the men for them to disapear... just ask for your bloodlineage to always be girls with a chance of futa, and then throught the genetics of your bloodline, it'll will slowly contaminate the human population until there is no boy anymore...
Better no boy will actually die because of that, so the transition will not be painfull for anyone.
There is no chicks with dicks john, only men with breasts!
So, what do you guys think is gonna happen when the seals are completed?
Probably goes back to full (human) size. It'd be cool if they got punished for something and they made them fairies to atone for it. This would be the yuri version.
