John is totally in love with someone he has only ever met four times.

He wanted to taste it; to lap at the darkness within Jim Moriarty's hollowed out soul and no matter how much the doctor tried to convince himself that it was wrong, he couldn't dispel the tiny voice in that back of his mind that caressed his thoughts with the whispered fantasies of a much darker man. Johniarty! Slash! THoB compliant!

[The Tumblr Faultline 27] Anonymous: Could you do something with insecure Omega John and a possessive alpha sherlock

University AU. Teenlock/Unilock. Sherlock and John meet by becoming roommates during their first year at university. Fun fluffiness and adventures and drama and smut and evil plots and good stuff like that. Ships: Johnlock, some Mystrade.

John has a series of unexpected meetings with a stranger on the Tube.

After being bitten in Afghanistan, John Watson is honourably discharged after presenting as an Omega. He is sent to the Centre, a location that keeps Omegas in order to pair them with a compatible Alpha through a five step process. For John, this place has become a prison. However, that is soon to all change for John when an Alpha finally decides to go through the process with him.

After being kidnapped off the street, John wakes up in a locker room. Not only does he find out Jim Moriarty's true identity, he discovers that he is in heat... and the only Alpha in the room is Jim Moriarty himself.

There were four facts about soulmates that everyone knew. One: every living soul had a soulmate somewhere in the world. Two: in order to identify one's soulmate, one had to make skin-to-skin contact with that person. Three: that soulmates, once they find each other, generally could not bear to be separated. And four: most people never found their soulmates.

John Watson had always assumed that he would never play a major role in Moriarty's game. He is taken by surprise when Moriarty makes a shocking demand: one month with John Watson in exchange for Britain's tactical positions and plans in Afghanistan. John has now become a pawn to be used as both Moriarty and Mycroft please. But what everyone forgets is that a pawn has power, too.

Lestrade brings his daughter to work. She's a bit of a handful, but, as it turns out, Sherlock's rather good at this. Albeit in his own, Sherlocky-way. ... "They're cute together, aren't they?" John sighs fondly from besides him. Cute isn't the word Lestrade would have used. Disturbing, sure.

Jim is a possessive little bastard. Not that Sebastian complained.

John was an army Doctor, he and other Omegas are captured and taken to a secret base for experimenting. Sherlock has never felt the urge to bond with an Omega, he loathes their weak and needy nature. Until he meets John Watson an omega with a stubborn streak and a delicious scent. All he wants to do is protect this interesting creature and he can't figure out why. AU SLASH A/0

Ridiculous but realistic adaptation if a toddler could melt Sherlock's ever cold exterior. Johnlock parentlock Rated M just to be safe!

PWP of the kinky kind with dom!John and sub!Sherlock. John is sick of the Woman's constant texting and decides to remind Sherlock who he belongs to. Rated M for a very good reason.

Sometimes finding your place in the world is a longer and rougher journey than you could ever imagine. Thankfully, you find the people to help you through it along the way. Alpha/Beta/Omega Dynamics.

Jim Moriarty didn't think he'd ever find his soul mate until he meet a nice normal fellow named Sebastian Moran. Jim wants to give him the world. He's not sure how he's going to do this without admitting that he's a criminal, but he's going to find a way.

Irene Adler has taken a step too far and John Watson is not an enemy you want to make. Dark!John/SerialKiller!Sherlock. Based on 'Get Off Easy' by Breath Carolina. Format Fix

AU. Mycroft's parents die and Mycroft is left in charge of four year old Sherlock. Gregory Lestrade just wants the four year old to stop sneaking into crime scenes, and maybe for Mycroft to give him his number. Mystrade. Told in Drabbles.

John is struck with a memory from his teenage years. / / "You drew this," John grins, pointing to the little drawing on the paper. "You gave it to me when you were five. I babysat you."
