A Companion (Moriarty x Reader One Shot)

You leaned in to lick his ear before continuing breathily, “And messy.”

He chuckled darkly, “You always have liked mess, darling… a little blood, some gasoline… I think that could work,” and then called out sharply, “SEBASTIAN!”

Moriarty’s right hand man appeared in the doorway in seconds, eyes flicking over his boss’s current position as the man grinned wickedly up at you, “Get (F/n) a puppy.”

He nodded and left as you leaned down to kiss Jim, his hand stroking your thigh before he moved to shove you off, “You got what you wanted, now off. I’m busy.”

“Who said I was done?” you breathed seductively, giving him a daring smirk.

He clenched his jaw in annoyance, “Off.”

“I promise I won’t get in the way,” you vowed, shifting to sit across his lap with your legs thrown over the arm of his chair.

He scrutinized you for a moment as he considered it. He did do his best work when you were near, something about you inspired the most devious and malicious of ideas and plans, and he couldn't say that he didn’t enjoy the fact that he didn’t even have to pay attention to you for you to be content. Instead of answering he simply went back to working, letting you snuggle into him while he went over his paper work.

This was how you remained for the next few hours, letting him work as you lightly stroked the edges of his suit jacket, until Sebastian reappeared, cautiously popping his head through the door, “Boss?”

Moriarty’s eyes flicked up for only a second but the man knew it was a demand that he come in and get to the point, which he did, stepping inside the room to reveal a small Rottweiler puppy tucked into the crook of his arm. You slipped off Jim’s lap and padded over to take it from him, giving him the same cold stare as the man you loved always did instead of showing the pleasure you felt inside. 

Once you had it in your arms, you padded back to stand behind Jim as he snapped, “Out,” and Sebastian gratefully slipped away, just being in the same room as the two of you when you were together was extremely dangerous.

As soon as he was gone, you plopped down in the center of the room to coo at your new friend, “Well look at you~ Aren’t you just so handsome?”

The little puppy’s tail went crazy and he pounced forward to gnaw at your finger as you scratched behind his ear, “You need a name… Jim, dear, any preference?”

He glanced up from his work again, “It’s your puppy. You name it.”

You glared at him and then turned your attention back to the puppy, keeping him busy with your hands as you thought, “ Would it be cliché to name him Hannibal?”

“Yes.”

You pouted for a moment and then simply declared, “Arthur.”

You pulled the puppy to you, cuddling him to your chest as he tried to lick your face, “You’re going to be ruthless when you’re grown, Arthur, tearing all the little people apart with those pretty teeth… Just like daddy.”

That caught Moriarty’s attention and he looked up to raise an amused eyebrow at you, “Daddy?”

You lifted the puppy above your face as you flopped back to lay on the floor, “You’ll be vicious, brutal, and so very menacing… He’ll be so proud of you. Won’t you Jim?”

He shook his head with a soft chuckle, he should have known that any pet of yours wasn’t going to just be a cuddly companion. You were going to make that dog as feared as you were and likely just as ruthless. He beckoned to you with a finger and you came to him, plopping the puppy in his arms when he reached for him. He scrutinized the little black pup carefully as he wiggled and then turned to give you a wide wicked grin, “You’re right. He’ll make a fantastic killer… though whether or not he will make me proud remains to be seen.”

You pressed a kiss to his temple, scooped up the puppy, and began to swish away so he could finish his work as you told Arthur, “Daddy’s busy. Let's go see if we can find someone to play with.”

Jim gave a fond smile at your retreating form before calling, “No blood on the carpet, darling.”

The only response he got was an adorably evil giggle as you disappeared through the door and he chuckled, a puppy was a better idea than he’d originally thought and you were happy. He liked that. There was a pained scream from down the hall from whoever you two had come upon and he grinned, he really liked that.
