Author's note: Just let me say that 1) I don't usually write slash, but this has been in my head for a while and 2) This is probably going to really suck. But if you feel confident enough, go ahead and read it. BUT, if you do read it, don't forget to review, the button doesn't bite.

Thank you! That is all! Enjoy!

John dozes in his chair behind his desk. It's quite a peaceful sight, his mouth is half open as it rests against his closed fist and his shoulders are slumped forward. His breathing is heavy, but quiet. The man leaning against his doorway doesn't want to disturb him. It's a pleasant sight watching someone sleep, especially if they're a peaceful sleeper like John is. The man in the doorway doesn't do anything but watch John sleep. And then finally to break the silence, never moving from the door he calls to the sleeper,

"Falling asleep are we?" The man's smooth Irish voice stirs John from his state of sleep and causes him to wake. Instantly alert he scans the room for the source of the voice, spotting the man at the door.

"Moriarty." He mutters under his breath. "What the hell are you doing here?" Jim steps into the room and leans against the wall across from John.

"I just wanted to chat. You can call me Jim you know, it's not like I'll murder you if you use my name." Jim smiles. "Sleeping well?" John ignores the question and glances toward the door. Jim follows his gaze and kicks the door shut before coming into the room fully.

"Who let you in?" John asks quietly. Jim offers a half smile before gesturing at his doctor's coat.

"It takes skill John." Jim purrs John's name, almost in a seductive manner before leaning against John's desk, facing the door rather than John. "The key is to blend in. Know how to turn invisible. How to hide in plain sight." Jim folds his arms and glances over his shoulder at John.

"There are people out there who need my help." To that Jim scoffs.

"People always need help John. And that help doesn't always come. In fact," Jim casually touches the desktop before continuing, "help rarely comes at all. And nothing you can do will change that." John frowns and leans back in his chair, an attempt to put more distance between himself and the consulting criminal.

"These people pay to be here."

"Should you really have to pay?" Jim asks, "Pay for help?"

"I don't have time for you. Get out." Jim smiles and pushes off the ground to sit on the desk.

"No time? And yet, you have time for a nap?" Jim grins, "I was standing at your door for ten minutes. John." He purrs. "Not getting enough sleep are we?" John shifts uncomfortably in his chair at the thought of Moriarty watching him sleep. He is quiet for a minute and then glances at his watch.

"I have an appointment. Get the hell off my desk and leave." Jim hops off the desk and moves to stand behind John's chair,

"Now you know as well as I do that you don't have an appointment for another hour. You're just trying to get rid of me." He leans over the back of John's chair and presses his mouth close to his ear, "Why?" John jumps, startled as Jim's smooth voice is suddenly much closer to his ear.

"I don't want you here." He says quickly, "I don't want you anywhere." He's nearly tripping over his words now, the thought of the consulting criminal so close gives him chills. Jim smiles and circles the chair, leaning against the desk facing John this time.

"Now John, relax. I'm not here to kill you." He puts his hands on John's cheeks, a look of true confusion on his face, and looks John in the eyes. "What I don't understand is why you're trying so hard to get rid of me and yet," he touches his forehead to John's. John can feel Jim's breath on his lips, and surprisingly, it didn't disgust him as much as he thought it would. "You are doing nothing." John freezes in Jim's grip and he stares into his brown eyes. Suddenly he realizes how close they are and in one movement pushes Jim against the desk forcefully.

"Get out." He whispers fiercely in Jim's ear before backing up, "Now." He says. Jim smiles.

"What are you going to do if I don't?" He purrs the last word. "You can't call security on my John. I work here now. Or did you forget so soon?"

"You get out yourself," John grabs the front of Jim's jacket, "Or I throw you out." Jim grins.

"Now would that be out the window, or out the door?" He covers John's hands with his own, causing John to jump again. His hands are soft against John's and that's what catches him off guard. Jim strokes John's cheek with one of his hands, a look of tenderness crossing his face. "You're so tense I can smell it my dear." He drops his hand before John can swat it away and his features harden. "So predictable. That's just like him. You're so human. I suppose that's why Sherlock keeps you around, to remind him when to stop. He needs someone to help him, or he'd end up like me." John's eyes flash.

"Don't you dare compare him to you." He says dangerously before landing a fist in Jim's stomach. Jim doubles over in pain, air leaving his lungs. Jim starts to laugh in an out of breath kind of way before straightening up and smiling.

"You just don't like comparing us," His voice is smooth, but out of breath, "because you know how similar we are." Jim takes a step closer to John, who's fist is still clenched. John refuses to look at him. "If he had made a different choice, it would be him standing here instead of me. And we'd be sharing a flat instead of you and him." His nose is inches away from John's, and he blinks slowly, "And you know it." John's breath hitches as he thinks about the truth behind Jim's words.

"Sh-!" His words are cut off by Jim's lips on his. They are soft and warm, like his voice. And he can tell Jim's smiling. In retaliation he grab's John's neck, his nails digging into the flesh of Jim's neck. The kiss ends abruptly as Jim lets out a yelp. He pulls back and glares at John,

"That hurts."

"Does it?" John whispers angrily. "What the hell is wrong with you?" He lets Jim go, and he rubs the back of his neck before answering,

"Many things. But don't act like you didn't enjoy it. I saw your face. Surprise and elation. Don't even try to hide it John. I'm not stupid."

"Don't."

"What John?" John drops his arms to his side and relaxes his neck.

"Don't. Just don't. Don't treat me like a pawn. I'm not a pawn." As much as he hates to admit it, John would love another kiss. He internally scolds himself. What the hell is wrong with him? He's confused himself, his mind and his body are confused, and he doesn't know what to do about it.

"John." He looks up to see Jim standing before him looking hurt. He puts a thumb under John's chin and pulls him forward. John tries to pull away, but Jim secures his neck with a hand and presses his lips to John's, softly, sweetly, chastely. John closes his eyes, enjoying the moment. What the hell? His brain is exploding, he doesn't understand anything anymore, and it's not that teenage 'what the hell is wrong with me' feeling, it's the 'my world just turned upside down and I don't know what to do about it' feeling. The fingers on the back of John's neck start to stroke his hair. Jim breaks the kiss and presses his forehead to John's. "We were made for each other." John gives up on trying to make sense of the whole situation.

"What's wrong with me? What's happened?" To that, Jim smiles.

"I happened."

"What?" John asks, as confused as ever. Jim leans forward and kisses John's cheek, trailing kisses down his neck. "Jim?" John asks breathlessly.

"Hm?" Jim presses against John, gently biting John's ear. His fingers trace the buttons on John's shirt as he kisses him again. John swallows his words when he feels Jim's tongue trace the crease in his lips. He knows that he shouldn't enjoy this as much as he does, but doesn't know how to stop feeling the way he does. Jim moves from John's lips to his neck, gently biting it and sucking. "Was there something you wanted to say John?" Jim purrs, blowing gently on his neck. John shivers and instead of replying fiercely kisses Jim's lips, all the while wondering why it felt so good to be close, to breathe in this man. John can feel Jim's chuckle of surprise as he pulls him close. Jim unbuttons the top button of John's shirt, and moves to struggle with the second button between John's hungry kisses.

And then.

As if suddenly realizing what he was doing, John stops.

"You're my enemy! I'm fighting against you JIM! This can't…." He gestures around the two of them, "It just can't… Work. Can it?" Jim smiles and pecks John on the cheek.

"We'll finish this conversation another time, but right now, I've got to be somewhere." Jim buttons up John's shirt and brushes past him, and John grabs his arm as he walks by,

"What do I tell Sherlock?" Jim turns back and winks,

"Sarah?" Jim gently pries his arm out of John's grip. "I'm a very careful man. He won't find out." He smiles warmly before exiting the office, leaving John rumpled, and confused, in the middle of it.
