Plot: Another Unlikely Storyline

I was walking back to my car after dinner, and passed a man with a young child, dressed up to look cute. Given sociological concerns over hypersexualised children (pick any minor age you like), my mind drifted to the scenario where a minor rapes her father, whether it is a trivial event in a plot, or a central plot device. The child would have to have been knowledgeable about what she was doing, and the adult incapable of resisting, so this opens up characterisations to elements of pity, grief, guilt, etc.This seems to fall into the template of Leon, and other Nabokovian fantasies of illicit social engagements, I suppose. Had to write it down for future reference.
