Sub!John -- Found!

[faerietayles.livejournal.com]

John was pretending to be a Dom because when he was younger he decided that he wanted to be a Dom. So on his papers it says he is a Dom. Doms weren't allowed to be doctors or go in the army. By the time that Subs could it was way too later for him to change his papers and not get arrested. He moves in with Sherlock who is a Dom (of course) And no one knows John is a Sub, until Lestrade figures it out (because John needs to go undercover as a Sub). Sherlock asked John if John wanted Sherlock to Sub for him. John freaked out. Sherlock eventually finds out due to a kitchen fire, and John following Sherlock's every command.

Any ideas?
