Sherlock and John had just gotten home from an extremely life threatening case. It had involved a guy who was a vampire, Sherlock of course, hadn't believed him until the man had turned him. Since then he'd been experiencing lightheadedness and the urge to rip into someone's neck and drain them dry. He shook his head, resurfacing from his mind palace and glancing over at John who had fallen asleep in his armchair and was now snoring lightly. Sherlock slowly arose from the sofa and quickly walked behind John, intending on getting himself a mug of tea. He stops short, he can smell John and hear the blood pumping through his veins. He wasn't used to all of this, his body was trembling with need. He slowly began to lean down, his lips hovering above John's neck when he suddenly jerks awake. Sherlock quickly moves towards the kitchen and John turns to look at him, a concerned look on his face. "Sherlock.. Are you alright mate? You look a little peaky." Sherlock merely nodded in response and began making 2 mugs of tea. John wasn't in the slightest bit convinced,Sherlock rarely made tea... He got to his feet and walked over to Sherlock, pressing the back of his hand to Sherlock's temple, frowning at the coolness of it. "I'm fine, John." Sherlock quickly moves away from his touch, biting his lip harshly and draws blood. He licks his bottom lip, getting rid of the blood that lay there. It suddenly clicked into John's brain what had happened and he cleared his throat before raising his arm to Sherlock's mouth. It took all of Sherlock's self control not to sink his fangs into John's arm right then and there, he held his breath. John frowned, giving him a look to tell him it was alright before Sherlock sunk his fangs into John's arm. He drank and drank the point where John was trying to shove him away, slowly becoming weak and dizzy. He was losing too much blood and knew if Sherlock didn't stop drinking then he'd be dead very soon...
