Lol every dev has the right to add any fetish he wants even if those do not make game per se more fun for some players, but why are those tags missing in that case if it is in game? Running into it without knowing it is a part of game is like for someone else playing a vanilla game and then having someone scatting into MC's mouth suddenly.
It is just not everyone's cup of tea and a fair enough reason not to play a game or to especially play a game if it is a fetish you like. Fetishes and taste will keep separating people until end of time.
I just wish people defended it less as necessary story where it often hinders a story and would just admit it is in cause they like it, which is all the reason needed.
