After being cured by Twilight's spell and creating the bat sanctuary in the apple orchard, Fluttershy learns that she still has some bat blood inside her. And that the bat side of her is thirsty. So thirsty...
[A/N: Rated teen for mild language, blood, mild violence and sexual references. (If this ends up rated mature, there will be no clop in it. Sorry, but this isn't one of those stories. Go read Triage for that). I guess this could be considered AU since it takes place shortly after "Bats!" But at the same time it isn't since Fluttershy did still have the fang at the end of the episode, and I'm just expanding on that in my own special way. Hope you enjoy!]
