I don't believe this prompt appears in the new version, Gutslut can be accomplished by never resisting Mika during the dream or in the labyrinth, by not resisting the Marie in the surgery room, by apologising to Rito for not being digested by her (but dont accept her offer as thats a game over), by telling Nala you'd let her eat you in the chat that occurs after escaping Mika when returning from outside, by interpreting the coin puzzle to mean 'Snake Eats Woman' and dont resist when the hungry maid pretends to want to eat you as seconds or when the shoe ghost pretends she is going to digest you in order to take a convincing photo.
