A few minor nitpicks:
Sometimes witches cast transformation spells unnecessarily - like a witch wil ltry to run you female into a male, then ride his dick. That's fine, but it als odoes that for a futa, which already has a dick. Kinda wasting the turn.
Even tiny dicks should still be able to have vaginal sex. There's no physical barrier to it.
I'm still not sure how amazons work. Do they always try to transform captives, regardless of thier sex? They captured on of the party (futa) and they seem to try and remove her D, which seems weird if they are capturing for breeding purposes.
Also, I seem to remeber seeing some messsage - do captured party members get preggo or impregnate amazons?
EDIT: Any way to remove scars?
