[Mainly looking for: Age difference (would require an AU since Harumi is canonly an ageless robot, though she looks like a kid), size difference, innocence, incest (AU of course), or student/teacher.]

[Also possible: Corruption, noncon, interspecies, forbidden love, bestality (as in monsters, aliens, demons, ect. No household pets or furries unless we're talking like werewolves or something plz.]
