I could 100% be wrong, but I think there is, or at least it's kinda implied to be, in future for me. But it will most likely be completely skippable, as you can choose who you want to be with from what I have seen so far. But don't take my word for it; I'm only making an educated guess.
Well, since you kind of flirt with the step-mother, there will probably be the option in there, but you don't have to follow that route if you don't want to. If the devs cut out everything people "avoid", then you wouldn't really have a game, now would you?
