Deliciously codependent recs?

[katielovesmusic.livejournal.com]

So I recently read wordstrings  Paradox Series, and it was wonderful. I am now looking for stories similar that have John and Sherlock completely entangled in each other to the point where it’s an obsession and borderline morally questionable the things they will do for each other. Even if it’s a little dark, that’s fine too. I’m desperate because this idea seems so cannon to me. I’ll take any verse though BBC is really growing on me.

Thanks so much in advance.
