Before I get started my idea is something you probably wouldn't normally see on a transformation site (atleast I've yet to see one like it)
My idea is about is about a group of Asian girls who are total whores for white guys, they also like to recruit other Asian girls into there faith(which is being whores for white guys) the leader finds an item that grants wishes(yea I know unoriginal), while she is consoleing one of her white female friends whose boyfriend broke up with her because he has a thing for Asian girls, the item activates when the the girl wishes she was Asian, the white girl becomes Asian and after a few more successful test the leader of the group decides to convert white girls into Asian girls.
