Yesterday I found a fic that I just loved. It's not finished yet, but it's being updated every week. The fic is "cantata for three voices in G major" by Wirefish1. It's a submissive but still in character snape fic with a virgin and inexperienced Hermione as his mistress (snape starts teaching her how to be a good one and what he likes), in my opinio beautifully written and looking as if it's going to profound in the characters personality. I loved that Snape wants to be a submissive but still keeps his IC personality (and not some fluffy behaviour).
Then I found "wizard in the basement, witch with the key" by wendymarlowe, which is too a submissive and IC snape with Hermione as his mistress.
I have never read a S/M where Snape is the submissive, and I was wondering if anyone knows any fic similar to this two. In character Snape.
