Virgin!Snape, powerful MM, randy AD/PN - and length! *koff*
Awesome! So much fun. So much *love* in this fic, for all your characters - including Crabbe and Goyle. I totally love how your fondness and focus on them lights up every paragraph.
Also, your "How Snape Lives" device was FTW! Hee, I wonder if Poppy noticed a moment's pause, or strange look on Minerva's face when she explained that?
It is all so *very* sweet. I particularly love how you show sides of these characters not usually seen, but which are clearly part of their complexity: boyishly randy Albus (OMG yes, the pleasure toy of Grindelwald), frankly earthy Phineas (of course! He's not just a Slytherin, he's a Black!); stressed-out fatalistic Snape (no doubt, given that year!); and powerful, clever, competent, sexy, Minerva.
YAYY for your multifaceted strong, smart Minerva! I think she's badly underwritten by most authors (including the canon one). I'd love to see more of her and Severus after he wakes up. She would surely be fighting for him against any in the Ministry who questioned whom he'd been serving. (er, or servicing, lol)
