I don't see incest as infidelity. It's just your wife and daughter both acting as your lovers. You basically made a mini-harem which isn't frowned upon. Incest and polygamy aren't taboo, it's just that not every monster daughter actually does it.

You could state that the chance on incest is about 25%. It either happens, or it doesn't. But in most cases it doesn't since both the father and daughter have to be into it. (Unless they are Dark Elves or Devilbugs, but you know..) If either the father or daughter says no, it won't happen. The mother will just go with it since harems are an 'accepted' possibility.
