Sherlock had taken notice of many changes in John's behavior of late (because really, there were many) but none was so irksome as his reluctance to reveal his teeth. John no longer smiled brightly and when he laughed, he always brought his hand up, as if being polite. More irritating even, John would hang his head when he spoke. He was hiding from the world, still refusing to come to terms with what he'd become. John could no longer walk in the sunlight (Sherlock preferred the moonlight anyhow), he slept all day in a room with newly purchased blackout curtains (No coffins in the flat, Mrs. Hudson would have suspected something), and drank from blood that Sherlock kept stored in the freezer (previously for experiments, now for John's unending hunger). But his teeth were what really bothered him (of all bloody things). His sharp, shiny, new teeth. And Sherlock was determined now, to see them, no matter what it took. It had become a game of what Sherlock could do to get John to accidentally reveal them, however, John had wised up to Sherlock's game quite quickly. It seemed John was twice as observant as he'd been before he'd become a vampire, and Sherlock couldn't help but adore the change, even if it meant he had to use twice as much brainpower to outwit his flatmate.

However, after weeks and weeks of trying to outsmart John and trick him into revealing those positively fascinating fangs, Sherlock's patience had worn thin and now he'd resolved to the simplest plan he could devise.

"Please John...? What harm could it do to let me examine them...?" Sherlock mused, twirling one of his long pale fingers into the hair at the nape of John's hair which now had a habit of growing unnaturally fast and had become quite shaggy as of late. John swatted Sherlock's hand away, growling a little, an impulse he couldn't really control. His baser instinct now was pushing him to just open wide and sink his teeth into his ever obnoxious flatmate. However, he knew that was something he simply couldn't do. Sherlock had even gone out of his way to prevent John from being too tempted. No more dangerous experiments in which Sherlock might injure himself (open cuts would be like an all you can eat buffet, obviously, Sherlock had thought) and he never let John drink from him. He'd bring back blood from only God knows where (John didn't have the strength to ask) for John to drink. Sherlock's persistence about his teeth was starting to wear him thin. It was so uncomfortable for him to reveal or admit that he was no longer just John. He was John, demon of the sodding night! John huffed heavily as Sherlock slid his head into John's personal space, gazing up at him with curious and prying eyes.

"Sherlock!" John snapped, giving the detective a good push, sending him flying back onto the floor. He still wasn't used to his own strength, and for a brief moment he worried that he might have really hurt Sherlock this time. Sherlock caught the glimpse of worry on his face and quickly decided to play it up a bit. He gave a sham groan of pain and rolled onto his side. In a split second, John was at his side, moving inhumanly fast.

"Sherlock! Bollocks! I'm sorry... So sorry... I keep forgetting..." John stammered, his tongue darting out over his lips as it often did when he was nervous. His pearly fangs were briefly visible as he did so and Sherlock's cheeks flushed with excitement. John was examining Sherlock for injury and didn't even realize he was biting his lower lip, his fangs curling down over soft supple flesh as he did so, and it wasn't until he heard Sherlock's heart rate increase that he realized what he'd done.

"Damn you Sherlock!" John said, jumping up and covering his mouth with one hand. Sherlock pouted petulantly as he slowly rose to his feet. No, that would not do. He needed to see those teeth. He had to.

"Don't do that John... Come now... You can be... Need to be... Yourself with me. Since no one else knows. Don't be ashamed John, show me your teeth." he whispered reassuringly in that sort of manipulatively warm way that Sherlock used when fishing for information from innocent people while on cases. John sighed heavily and let himself be turned around. As his eye's met Sherlock's John slowly opened his mouth and Sherlock lit up like he did at a particularly fascinating crime scene. It was both irritating and flattering. Sherlock slid his index finger along one of John's slender and sharp fangs, his skin tingling a bit at the feel of the venomous thing against him. It was a familiar rush, knowing John could easily over power and kill him in a heartbeat. Sherlock was never bored, knowing that he was risking his life by pushing John's buttons like this. John could bite down and poison him with those fangs in milliseconds. Sherlock shivered at the thought of living eternally and solving cases until the world literally faded to dust. Thrilling. He and John against the world for an eternity. Just the thought that he had the option right at his fingertips was amazing.

"Beautiful... You're such an incredible specimen John." Sherlock praised softly, gasping suddenly as John's fang-tip caught his skin and a little pearl of blood rose out of the puncture. John's eyes fluttered briefly and then he groaned, causing Sherlock to nervously yank his hand away. John covered his mouth with his hand again, coming to his senses once craving that rushed through every inch of his body was overwhelming for a moment. The smell, the way he could almost taste Sherlock, it had all been so amazing and so wonderful and pleasurable.

"Happy now?" John growled defensively, curling in on himself. It was an embarrassment to want to devour one's flatmate. A disgrace even. "You finally get your fill?" John's tone was harsh and accusing, causing Sherlock to cringe a bit. It was like an animal inside John had spoken instead of his sensible army doctor. Sherlock didn't answer right away, actually mulling John's question over seriously. John was storming away for a shower to calm his frayed nerves as Sherlock came to his conclusion, knowing without a doubt how he felt.

"I'll never get enough..."
