Eep, I enjoyed Snupin! Eeeeeep, I enjoyed Snupin with cross-dressing (both things I usually run away from)! No, seriously, that was fun! I adored the characters in particular. Snape's insecurities, Remus's pushover-nature. Loved the realism of it – the awkwardness of Remus' first reaction, Remus's concerns, the actual reactions... great fun.
I particularly loved Remus might be susceptible to other people's opinions, but Severus didn't give a damn about what any of them thought, and imagining the look on the faces of Molly Weasley, Potter, and the rest when they found out was enough to put him in a good humor for the rest of the week. Just because... that's Snape in a nutshell, and I adore it :).
Loved Minerva, and the sex was very hot (and, again, lovely realistic!).
