Sure, that’s a certain kind of scary, but imagine the experience of being forcibly given a desire you’ve never known. Imagine you’ve been living as a more or less average human your whole life, and suddenly this creature turns up that instills a mind-warping hunger for something essentially mundane but culturally, slightly embarrassing or inconvenient to satisfy, like a growing need, only temporarily satiable, to have someone else’s finger in your mouth. You can fight it, sometimes holding out for days at a time, but you experience a continuously intensifying, survival instinct level drive to lick, or suck, or simply hold in your mouth, someone else’s warm, living fingers.

‘We call this creature The Dentisubus.’
