Sorry, it's a massively Dark!Fic, and from what I've been reading, it's not as scary/dangerous as one would generally believe. Not that I'm willing to try it, I myself am happily vanilla. However, Dark!Zev is Dark!, and if multiple exclamation points weren't silly, I'd put more of them into that description...

It's the psychological effect on the F!Warden that he's aiming for - the violation and proof that he can do anything he damn well pleases, and make her like it - that I'm looking for, and that's why it's there.
