Of course, the problem with the emphasis on the fellatio is, have you noticed how it always comes first in porn? To show how eager the woman is, and all that. It's got to the stage where showing fellatio is basically a way to show a woman's gagging for it. And her urge to please is always stronger than her interest in her own pleasure, hence the returning of the favour coming either later or not at all. Mind you, there's no cunnilingus at all in my fics. No naked women either, for that matter.

What fandom's your succubus thing in? It sounds intriguing.
