He’s decided to just be himself, cliché as it sounds. The lie about being Sherlock’s mate will be difficult enough to keep up, he’s not going to think up more of a charade regarding himself on top of that.
If he uses the wrong fork at dinner, fine. If someone calls him on it, he’ll just stab them with it. Job done.
First attempt at Omegaverse because a very good friend of mine likes it, and I like my friend. She asked for: alpha!John/omega!Sherlock; age difference; pretend bondmates to meet Sherlock's family; synthesised bond scent; and bonding in Sherlock's old bedroom. I think I'm managing to cram it all in for you, sweetpea ;)
No mpreg, I'm afraid. That was a stretch too far.
