As big as the Star Wars fandom is, I've seen very little ABO fic.

I'm looking for some Alpha!Obi-Wan/Omega!Anakin please! It could be AU in that they've always been that way; maybe they go to a planet that somehow changes their basic biology; a Separatist/Sith plot; a spell by the Nightsisters...any reason at all is fine with me, I just want some submissive Anakin & dominant Obi unable to keep their hands off of one another.
