Are redundant.
Mixing two rape metaphor monsters does not produce rape metaphor monster2.
Wait, since when are vampires
or succubi metaphors for rape? Vampires pretty much started out as metaphors for
disease (medieval revenant-types,
Nosferatu, etc.), with a side effect of seduction ("The Vampyre," in which Ruthven was pretty much a stand-in for Lord Byron and his effective although dubious charms;
Dracula, in which he would corrupt all the virtuous Englishwomen into being seductive creatures of the night*). Vampires who engage in assault tend to stay away from
sexual assault and confine it to, well, "tiger pounces on cow and eats it." Really, the major exception comes in paranormal romance novels and urban fantasy, where vampires aren't so much "rape metaphor" as they are direct analogues of rapey alpha-male romance leads** and the fact that they have fangs is entirely incidental. Heck, the werewolves are almost always the same, yet more so. (In-story, Catt seems to be part "darkly seductive temptress," if you're a maid, and part "voracious assault predator," if you're not.)
*Though honestly, it's entirely possible that was all just subtext; analyzing
Dracula as literature is way beyond this thread. But to the extent that
Dracula is a sexual metaphor, it's a racist metaphor for how hot foreign guys will turn innocent Anglo-Saxon girls into twisted creatures that actually *gasp*
enjoy carnality!!! The absolute
horror!!!
**And discussions of the role of sexual assault in
romance novels is
way outside of the topic of this thread, I think. Unless ES has a sidestory thread running over in Sufficiently Sexy about Cattelya and her maids that I don't know about.
And the entire
point of succubi is that they tempt you into sexual activity that the "virtuous" person would otherwise avoid. They're not about raping you, they're about tempting you to exercise your free will and give in to the sin of lust. (A big part of medieval succubus mythology, after all, is basically to explain why genuinely celibate monks get wet dreams. The Devil was sending hot girls into their dreams to try to tempt them when their guard was down!
