When it comes to this or any kind of "monstrous agression" done by the woman, like the ones below, my take is to engage in mutual violence until:
-Woman is defeated and made to submit -Woman dies (if too evil) -Mutual destruction -If woman "wins" she gets permanent suffering -Only sympathetic if she does this because she is cursed to do it
Romantic (?) vore is not my thing.
I did "write" a story in my head where a monster girl ends eating up the heart of a man she admired, but as a tragedy, and she ends up miserable after it.
So, I don't think I am your guy for this type of plot.
