I have a mother and a father and an older sister. And a whole fucking tree full of uncles and aunts and cousins and cousins once/twice/thrice removed. That doesn't mean I relate every incest fic I stumble over to my own situation, so don't do it to yours. It's fanfiction. And even if you can't manage that, it's not that hard to remember the age old Don't Like, Don't Click.
