>>17733068It's not that tricky, you're writing it from the point of view of the victim so the taboo isn't a big deal, just make sure the villain is cartoonishly villainous and the pedo-rapist angle is just a different form of kicking the dog.
Then make the hero in the fantasy a young man who is "saving the princess" only it turns out he is the princess imagining herself the dashing prince coming to save her. Throw in some subtext about penis envy and female interpersonal rivalries. Definitely got to fight mum at some point.
After that it's just about worldbuilding. And you've got a get out of jail free card because anything that doesn't make sense is explained by it being the hallucination of a drug fucked teenage girl.
Badda bing, badda boom, awards please.
