I don't know if you've seen it yet, but I have a delicious list (http://previous.delicious.com/bella526) with all my favorite bottom!Draco fics. You can use the tag to sort through them by length, pairing, rating, etc. Check it out!

Also, Appleling & Meretricula have great fic lists too. (The links are on the right sidebar of the main page.)

I hope this helps! <:)
