Not a bad idea. I agree with the whole teasing aspect of the demoness. Being able to watch/read of an orderly member of such a once respected organization be reduced to a babbling cunt-craver would be too much almost. A well written story would have me drooling for hours, probably.
That's my hang-up though. It would need to be well written - preferably by someone who knows something about how the order of priesthood works. Preferably a woman too - one that knows how carefully yet devistatingly pick away at the male mind.
Anyone else's thoughts?
