Hee, I had to come back and reread. OMG, this is just as good on the five billionth read as it is on the first. So twisted and wicked and lovely and hot. Just so very exactly Snape. My main goal this read through was to form a coherent response for you (the first I left over on LJ was just... not, lol) but I think I'm not going to be able to do it this time either. The response you evoke with this is just so visceral that it really is hard to pin it down with words.
But I'll try. :D
You took my prompts and wove them into such a wonderfully corrupt tale of abuse of power (whee! kink!!) and did it so skillfully! I am left tingling every time I read this (and I've literally been back at least once per day). It is so very perfectly the sort of fic I just love to tiny pieces, because it is gritty and real and provokes the Muahahaha factor. No matter how many times I read this, I want to just chuckle evilly at the end. Maybe a bit of wicked-gleeful handrubbing. :D Seriously, you're awesome.
