This fic is for http://lokiarrty.tumblr.com for their prompt on the Johnlock valentines day gift exchange! I apologize heavily if this seems badly written or rushed. I'm a bit new in a way to writing this type of story and tried my absolute best! TITLE: If I Was Your Vampire RATING: M It was nighttime and everything was silent on the streets. John Watson quietly left his flat as he made his way to the alley, observing the streets from the darkness. Moments later a young teen walks by and John could smell him as soon as he neared the alley. John smirked and silently approached the teen, covering his mouth as he dragged him into the alley. John turned the teen to face him, staring into the fear laden eyes. "Stay quiet." He commanded and as if under hypnosis the boy followed the command. John leaned forward, the scent of the boy's blood strong and delicious in the air. He nudged his neck before biting into the thin flesh. The sweet and tangy blood flowed over his tongue in a wave of flavor. He sucked harshly for just a few moments before pulling away. John licked the wound, watching it heal before his eyes, and let go of the dazed teen. "You're going to go home, sleep, and forget that this happened. You simply got lost while on your late night walk." The boy nodded and left the alley. Once under the streetlight again he simply shook his head and looked around. He whispered 'where am I?' before shrugging and leaving. John sighed and returned to his flat for the night. That was simply a snack. Not enough to fill him...just enough to stave off hunger for a bit. John retired to his room to sleep for a bit. The next day John bumped into an old friend, Mike Stamford, from his short lived university days. They chatted a bit when Stamford mentioned a flat share and John chuckled. "Who would want me for a flatmate?" Stamford laughed. "You're the second person to say that to me today!" John raised a brow. "Well who was the first?" Moments later John was face to face with a man he could only describe as hauntingly beautiful. He was tall..at least six feet tall. He had unruly curly black hair and striking blue-grey eyes. His skin was pale as snow and his face looked like a sculpture. He had sharp high cheekbones and an angular chin. He wore semi-formal dress clothes with a long dark coat and a navy blue scarf. John was practically his complete opposite with his sandy blonde hair, short stature, and awful habit for wearing jumpers. The man babbled on about some experiment he was conducting before turning away from the two men. "How do you feel about the violin?" He suddenly asked. "Hmm?" "I sometimes play the violin while I'm thinking. I barely eat or sleep and sometimes I go without talking for days." He turned to John. "Potential flatmates should know these things about each other. Meet me tomorrow and we'll discuss thing." "Flatmates? I don't even know you're name or where were meeting." The man grabbed his coat and stood by the door. "The name is Sherlock Holmes and the address is 221b Baker Street." He found the man's blog that night and he seemed to have quite a bit of odd.....hobbies? Yes hobbies you could call them. Ranging from types of tobacco ash to how you can tell the difference between dried blood and mud or other substances. He seemed strange to say the least. The two met at the flat the next day and John was thoroughly surprised and uplifted by how nice a place it was. They discussed payments and such and Sherlock showed John his room. John happily accepted the idea of being a flatmate to this strange man. Though to be honest John was already convinced that Sherlock was a vampire. A few days later John was completely moved in and all was well. John spoke with Lestrade, his only vampiric friend in London, about a month into living with Sherlock. "It's weird Greg. He doesn't rarely ever sleep or eat. He really only drinks tea every once in a while. I think tha-no I'm sure! He's got to be a vampire!" Lestrade chuckled. John raised a brow. "Sherlock Holmes a vampire? Your kidding right? I've been friends with his brother Mycroft for years! The Holmes family is vampire free. That I can assure you." Suddenly John felt like his life with Sherlock was about to get a lot more complicated. "You couldn't tell though? I mean the Holmes's blood has an especially strong scent. Hell i couldn't stay away from Mycroft once I first smelt that delicious blood. I was lucky he let me feed from him though." John shook his head 'no'. "I guess I haven't since I was so sure he wasn't human. I must be careful around him then. He's very observant and if I slip up my cover could be blown in a matter of seconds." John and Lestrade chatted a bit longer before John retreated back to the flat. Sherlock was having a nap on the sofa apparently. It was the first time he slept in a week days. John moved to place a blanket over the sleeping detective when it hit him. An exceptionally strong scent of blood. It smelt sickeningly sweet and John instantly wanted to taste it. Before he realized it John had leant forward and was practically pressed against Sherlock. He quickly drew himself away from Sherlock and laid the blanket on top of him. He retreated to his room and cursed his impulses. He was hard just at the thought of drinking that sweet blood. He could imagine it so vividly. Having Sherlock lying in his arms begging John for more as his blood flowed freely over John's tongue. "Fuck...." John hissed as his cock jumped at the thought of drinking from Sherlock. John left his room to take a cold shower and calm his nerves. Sherlock awoke the moment John came home but had pretended to sleep to see John's reaction. He was pleasantly pleased to know that he was right and John was in fact a vampire. It didn't scare Sherlock at all. If anything it actually enticed him. Sherlock's heart raced uncontrollably when John pressed against him. He wanted to know how far he could push John before he would break. He wanted John to feed from him. Not just as an experiment but because he was simply curious. He had heard from Mycroft once that a vampires bite can be either pleasurable or painful. 'Some say it is better than sex' Mycroft had said. Sherlock was not really a person into sex but....this was different. He needed to know how it felt...how John felt. Once John came out of the shower Sherlock was for once preparing dinner for them. He was chopping up some vegetables when John heard him shout. "Shit!" He yelled as he quickly pulled his finger away from the cutting board. "Sherlock are you alright?!" John rushed over to him. His finger bleeding a bit but the cut wasn't too deep. John caught that scent again and his fangs where already showing. He rushed into the bathroom. "Wrap it and put pressure on it! I'll find bandages!" John took a deep breath to calm himself. Once calm he found the kit and returned to Sherlock. There were drips of blood on the counter and it was driving John absolutely mad. John practically threw the first aid kit at Sherlock before beginning to walk away. "Why don't you just drink it John?" He asked calmly and John froze. Sherlock had figured out John's best kept secret. "What the hell does that mean?!" John said as he turned to face him. "I know what you are John. Honestly you were terrible at hiding it. Like right now your fangs are pretty visible." John cursed all that was holy and marched towards Sherlock. He grabbed his finger and looked at it. He licked the wound to clean it of blood and groaned at the taste. He pulled away and bandaged his finger. "Fucking hell Sherlock you taste amazing..." John said as he let go of Sherlock's hand. "Want more?" He said with a smirk. John grabbed Sherlock's arm, leading him towards his room. Sherlock was pretty much thrown onto the bed as John climbed on top of him. Sherlock removed his shirt and lay back on the bed. "That little bit of my blood and you're already hard John?" Sherlock chuckled. "Fuck you." John replied before leaning forward and licking up Sherlock's neck. He moaned as he sank his fangs into the flesh. Sherlock's blood was filled with the taste of arousal and pride. It was infuriating and delicious all at once. Sherlock gasped as John finally sunk his fangs into his skin. It hurt at first but it became quite pleasurable as time passed. Sherlock bucked his hips against John, his pants becoming incredibly too tight. John removed his fangs and licked the wound to heal it. Sherlock was looking at him with eyes full of lust. John leaned forward and placed his cold lips against Sherlock's warm ones. John slid a hand down Sherlock's chest to rest on a bony hip. Sherlock moaned against John's lips. His hips were one of the few sensitive areas on his body. John smirked and lightly scraped his sharp nails against Sherlock's hips. "Ahhh! John..." Sherlock gasped and arched into John's touch. Suddenly Sherlock caught John off guard and flipped them so that he was on top. Sherlock quickly rid John of his undershirt and jumper before attacking his neck with kisses and bites. John hummed happily as Sherlock moved his way down the vampire's body. He left butterfly kisses and playful nips to each area of John's chest. "Clothes off NOW." Sherlock commanded, his voice rough with arousal. John did as told and slid off his trousers and pants. Sherlock did the same before pressing against John and pulling him into another searing hot kiss. John flipped their positions one more and ground his hips against Sherlock's lithe form. Sherlock practically snarled in annoyance at John's teasing. John then pulled Sherlock into a kiss to quiet him as he reached into the bedside table for a specific item. Once he found the lube John pulled away for just a moment to coat his fingers with it. Once thoroughly coated John guided the first finger to Sherlock's entrance, teasing it with the tip of his finger. Sherlock whined. "Get on with it John!" John once again followed the command and pushed the first finger through the tight ring of muscle. Sherlock squirmed a bit at the odd sensation and John stroked his cock to relax him. Once Sherlock got used to the intrusion and the small thrusting motions John made, he added a second finger. Sherlock hissed, a sign that it was just a tad painful. John pulled him into a quick kiss and nipped his bottom lip. "Patience. It'll get better...promise." John thrusted his fingers in and out of Sherlock for a while before adding the third and final digit. Sherlock was used to the feeling by this point and whined at the overwhelming sensations of Johns fingers inside him and how John was still stroking his now painful erection. "Please John...." He begged. John smirked, feeling accomplished to have made Sherlock Holmes beg for him. John removed his fingers and lined himself up with with Sherlock's entrance. He pushed in slowly, not wanting to hurt his friend, lover, whatever you might call them. Sherlock winced a bit and John stopped to let him adjust to the intrusion. Slowly they moved on and moments later John was fully sheathed inside Sherlock. John was panting, waiting for Sherlock to give him the sign that it was ok to move. Sherlock squirmed a bit before nodding at John. John pulled out slowly before slamming back in and groaned loudly. "God Sherlock...so tight." Sherlock gasped as John slammed into him repeatedly. Moments later John hit a spot that had Sherlock screaming. "Christ John! There...again...!" He said between shaky breaths. John picked up speed with his thrusts and trailed his hand down Sherlock's body to stroke him once more. Sherlock looked at John through glazed over eyes and said two words that made John nearly lose himself then and there. "Bite me." He breathed out as John moaned. John happily nuzzled Sherlock's neck before sinking his fangs in. He thrusted into him shallowly as he drank from him. Sherlock was arching his back into John's touch, completely lost in the sensation that was John Watson. Moments later Sherlock took a shaky breath and screamed. "John!" He yelled out as his release splashed across his and John's stomachs and chests. John helped Sherlock's wound before pulling away and thrusting wildly into him, chasing after his own release. With Sherlock's walls spasming around him he finally lost control and his hips faltered as he moaned out his lovers name. John pulled out of him and collapsed next to Sherlock on the bed. Once they caught their breath Sherlock spoke first. "Mycroft was wrong." "What?" Sherlock turned to face John. "He said that a bite was better than sex. Don't get me wrong those bites were amazing but...nothing is better than sex with John Watson." John smiled and laughed. "Sherlock you crazy git!" Sherlock moved to lay his head on John's shoulder. "So where does this leave us?" John asked lowly. "As a couple of course. I want a LOT more of what just happened." John chuckled as did Sherlock. "Alright. I'm exhausted....sleep?" Sherlock nodded, his eyes already closed as he snuggled against John. John pressed a kiss to his forehead before drifting into unconsciousness.
