I just read a lovely humour fic that I want to recommend. A small break from all the angst we all (me included) seem to enjoy.
An Acquired Taste by kinklock
Summary: At Montague Street when Sherlock was forced to sate his body's needs, he was at least able to wander about the flat as much as he pleased.
At Baker Street, it was mini-bags in a mini-fridge and bedroom confinement.
In this fic, Sherlock is a vampire and the story tells about how John finds out and how they journey from friends to lovers from there. It's a humor fic which is also warm and sweet.
Also, Sherlock is a bat. That is,he can shapeshift into a bat. Now, even though I usually enjoy vampire fics, I draw the line at bats. Just too... out there for me. But since it was a humor fic I thought I would give it a try - and I LOVED it! I found John's interation with Bat!lock so amazingly sweet and adorable that I am now looking for more John-bat!lock-fics.
And this story doesn't involve any kind of violence or dub-con as vampire fics might do. It's all pure consensual, sweet, humorous and lovely. (There is blood drinking, though, read the tags).
I found this fic hilarious and toe-curlingly sweet. And now I want a bat.
