Slamming up against the wall, Sherlock twisted his head so he wouldn't break his nose from the impact and also to aid his visual of his attacker. John was out tonight, a date with some tall, willowy-bodied, dark haired woman who was nothing like John's type and was already occupied in an on-off relationship with her ex who currently was suffering from genitial warts... he wouldn't be back for another 2 hours at least, which meant that either this attacker was very good at cooincidence or he had been watching 221B for quite a while. Really, Sherlock was pretty happy that John wasn't here as his attacker suddenly gripped his wrists and shoved him back against the wall, giving Sherlock a clear view of his face.
"Oh Sherly, you better watch out. My gun might go off prematurely if we stay at this close proximity." Moriarty sniggered, pressing his body into Sherlock's back and beginning to nibble lightly on the earlobe that was so perfectly presented to him from the way that Sherlock's head was twisted. He heard a small gasp leave Sherlock's lips, which made Moriarty smile and roughly bite down on the consulting detective's now sensitive ear until the gasp had turned into a hiss and the thin frame that was trapped within Jim's grasp began to squirm.
"What game are you playing this time, Moriarty?" Sherlock snarled, his voice barely more than a whisper as he bit down on his lip. Feeling Moriarty buck up against him, the criminal's hard length pressing up against him even through the layers of trousers and underwear between them, Sherlock couldn't help but feel a small twinge of fear rumble in his stomach.
Jim moved away from Sherlock's ear and moved downwards, licking a line from ear down along the tendon of neckbefore finally finding the protruding collarbone. Sherlock was unintentially arching his head up, almost inviting him in to the beautiful collar and that long neck of his. "Not a game this time, Sherly, so~rry!" He laughed, nipping at the collarbone and grinding the skin and bone under his teeth until he was sure there would be a bruise. "This time, I'm not playing around with you... I want to play with you." His voice ended on a growl as he suddenly twirled Sherlock around by the wrists until he was back against the wall and mouth full of criminal tongue and rough want.
