Where are the Futanari girls at? Or is the player the only one capable of being a Futanari?
in some fights after you win you can have them grow a cock if you know the spell - for sure with the bandit girl (not Alissa, the random encounter one (although if I remember correctly there may have been a futa!Alissa scene at some point too? don't quote me on that tho)), and I'm not sure but maybe with the student succubus? Also you can have Marin do the second challenge as a futa, but she doesn't let you see, so you only have the text. There's also a punishment scene for Edith; there may be some other scenes too, just try different interactions after you learn the spell, they are usually temporary but they do exist!
