Will you add an option to disable the incest? perhaps with slightly different text for the conversation with your mother?

It's the first time in three years that anyone asks for it, so I don't think it's a big issue with the vast majority of the players. It's not super complex, though, so with very little practice in Renpy you can make yourself a patch that will overwrite the scenes ("Labels" in Renpy) you wish with your own text.
If I see more demand I'll consider adding it, but don't hold your breath.
