This is My first ever Fanfic so please be gentle with me. :)

It was just on 10pm when Perci heard the slight knock on her door. She knew instantly who it was, as the knock was not made by a fist but by the gentle tapping of wood on wood. Three soft taps in prompt succession. Mr. Holmes.

She knew that he could easily let himself in; given his association with the other residents of Baker St she was sure that he had a key to this apartment as well. Even though the title agreement now said that it was legally hers, she hadn't bothered to change the locks when she moved in. But Mr. Holmes was too polite to enter unannounced.

She got up from her kitchen table and navigated her way around a pile of wallpaper, paint and sample fabrics to answer the door.

"Mr. Holmes, what a pleasure to see you. Please come in." She said softly

Not waiting for his response she twirled back towards the kitchen and set about clearing him a space to sit on the other of only two chairs. Spread out on the table was an array of brightly coloured paper squares in the process of being folded into geometric shapes.

"Good evening Ms. Miles. I apologise for not calling first, however I found I had to attend to one of Sherlocks many whims and thought I might impose myself upon you briefly before leaving. How are the renovations progressing?"

She watched him look around and take in the mayhem and somehow knew that he hardly needed to ask to know that they were progressing slowly. She coloured slightly when she saw him looking at the pile of dishes in the sink and rushed to apologise. "Sorry about the mess, I was baking earlier. It's fortuitous that you came today, as tomorrow I know that Sherlock will have eaten them all. For a man who hardly eats he sure can put away cookies. I never even have to tell him that I have baked, he's like a dog as soon as he smells it he's down here polishing them of at an alarming pace before once again disappearing at breakneck speed."

"I regret my brother's lack of manners, he was raised better, but you wouldn't know it from the way he behaves."

"It's no trouble really Mr. Holmes. I like to bake, it's relaxing and I find Sherlock's enthusiasm for my food flattering." A smile lighting her face and emphasising her sincerity.

"And what is this" He asked, gesturing to the table with the hooked end of his umbrella. "Another relaxing hobby?"

"Yes" She laughed slightly. "Most people would find it very boring and tedious. It's a form of modulated origami called Kusudama and whilst the end product is impressive, the actual making is very repetitive. I like it however because of it's geometric symmetry. I also once watched a documentary that looked into the practical applications of the art, for instance they use it to make models of molecular structures and to economise the folding of airbags in commercial cars."

"Fascinating."

"Sorry, I don't mean to be boring." Looking at him she realised he was still standing and wearing his coat and gloves. "May I take your coat Mr. Holmes; you look as though you are about to bolt out the door."

"I don't want to impose given the lateness of the hour."

"It's really no imposition. I'll just put the kettle on and we can enjoy a few of these biscuits before the fiend upstairs scoffs them all." She walk to his side and waited for him to remove his coat before folding it neatly over the back of the couch. "I still haven't gotten any hooks, no point until I finish the wall paper" She explained.

He sat and gracefully pulled at the tips of his gloves before collecting them together face to face and setting them to his left on the table. They looked so dark and severe resting amongst the soft paper squares. As she put the kettle on she watched him out of the corner of her eye. He had pushed the chair back from the table and sat with one knee crossed over the other and his hands resting lightly on said knee. With his back straight and chin slightly raised he looked effortlessly confident and extremely posh. She suddenly felt underdressed in her leggings, cream tunic dress and charcoal cardigan; the ugg boots certainly didn't add any class to the ensemble. But it was late and he had called by unannounced so she felt he couldn't hold it against her.

That said she was sure that Mr. Holmes would never be caught dead looking anything less than perfectly polished. Here it was 10pm at night and his suit looked like it had been freshly press and when she had taken his coat before she couldn't help but notice his fresh but masculine scent.

She set about putting cookies on a plate and setting out the tea. "Is earl grey ok?" She asked knowing already that it would be, but still it was polite to check. He didn't verbalise his answer just indicated his consent but lifting his chin and letting a small smile come to his lips.

She set the tea pot and cups and saucers on the table and went back for the rest. As she moved around she felt his eyes on her and knew that like Sherlock he must be deducing everything about her. She never felt so naked as when she was with the Holmes brothers. However whilst it was disarming, it was also somewhat arousing and since buying the basement flat at 221 Baker St five months ago she found that their company was exciting.

Mr. Holmes had explained that he held a minor position in the British government which kept him more than busy with a plethora of paperwork and menial tasks. Perci however was not convinced. She most certainly was not Sherlock, she couldn't look at someone and know them, but she wasn't as fool either. Minor positions in the government did not come with the sort of cars, assistant and hours that Mr. Holmes had. They also did not wear suits of the quality and expense as the man sitting across from her.

His wardrobe was a work of art. Never a stitch out of place, the expensive wool fabrics hung in a way that showed the craftsmanship of their making. Always in a three piece suit… she liked to count the number of buttons. Today there were two on his jacket, four on the waist coat and she estimated twelve on his shirt. The chain of his pocket watch caught the light and contrasted beautifully with his soft grey suit and cornflower blue tie.

She pulled her mind back to the task at hand and pushed the paper scattered over the table to one side to make more room. Pouring his tea she felt her cheeks warm knowing his eyes were on her.

"I hope that you enjoyed the opera the other night? I was wondering if you might like to accompany me again some time?"

"Yes Mr. Holmes, I enjoyed it greatly. I would be delighted to go again if you ever find yourself with a spare ticket, but please do not go to any expense or effort on my part."

"It is no trouble at all Ms. Miles, it is actually nice to go with somebody who enjoys it. It have previously asked my assistant to join me on the rare occasion that I have time to go, but I know that she only tolerates it and more than once I have caught her distractedly checking her e-mails on her blackberry."

"Blasphemy!" She exclaimed with a chuckle and mock slamming of her hand upon the table. "Oh well at least you know she is dedicated to her job."

He smiled.

The minutes ticked by and they both sipped their tea and ate the cookies. Suddenly he stood and collected his gloves and picked up his umbrella from where he had leant it against the table edge.

"It's late and I should be going. Thank you for the tea and the biscuits, I can certainly see why my brother likes them so much." He politely stated.

She stood and moved quickly to the couch to hand him his coat. His scent was all around her again and as he took his coat from her his hand brushed her bare skin. He paused in his movements and remained with his fingers just touching the tips of hers. Suddenly it felt like the air around him had been sucked out of the room. He knew that he need to leave or else he would do something that he could not undo. Sill he stood there and he looked at her, saw her eyes dilate, her breath get shallow and faster… she wanted this as much as he did, he realised with a shock. She was so young, only just 29 and he was less than year shy of an embarrassing 40th birthday. He should leave now.

Instead he quickly pulled his coat towards him and in the process pulled her off balance and into his arms. His umbrella and gloves fell to the floor unnoticed as he leant down the foot need to capture her lips. The kiss was firm and slightly desperate as he felt her stiffen in his arms and he feared that for the first time in his life he had read the situation completely incorrectly. Then she was rising up on her toes and pushing her body towards him as she opened her mouth and he deepened the kiss.

He felt all his self control snap like a rubber band stretched too long and too far. He pulled her away from him and his coat, which had previously been caught between their bodies, fell to join his gloves and umbrella on the floor. He took her shoulders roughly and spun her around, bending her over the back of the couch in one fluid movement. With one hand pressed firmly in the small of her back he used the other to push her short tunic up and then pull her leggings and knickers down at once.

The soft pale globes of her arse and her pink cunt were bared before him and he felt a low grown of appreciation escape him unchecked. Without preamble he slid his hand over the right sphere of her creamy backside and pushed two finders into her. She was already wet; he had not been wrong at all. He pulled his two fingers out and spread her arousal around before running them over her swollen clit. The small mewls that she had been making were quickly replaced by a sharp intake of breath and a ragged exhale but she didn't say a word to stop him.

It had been so long since he had had a woman, being so busy with work was just one reason, but in truth he found most women vapid. Too many social climbers were attracted to him like sharks to blood in water and he found their desperation transparent and vulgar. Perci was different. She was comely and sweet, but under that there was a sharp edge of intellect and a vivaciousness that intoxicated him.

He knew that he should take his time, he knew he should leave and come back and woo her properly. He knew he should but instead he dropped to his knees and buried his face in her slick cunny. She hissed with appreciation as he swiped his tongue from her clit to the tight pucker of her arse before coming back to suck the bud into his mouth.

He leant back and used both hands to pull the outer lips of her vagina apart and admire the flushed pink colour of the delicate parts inside. She had been waxed and all that remained of her pubic hair was a small strip not visible from this angle, but which he had felt before. He would have to change that… he wanted her natural, not like a girl but like a woman. Even still the sight of her caused his erection to throb against the zip of his suit.

He wasn't blind, he knew that when it came to looks, Sherlock had gotten the lions share with his curly dark hair and lithe body, but he had been blessed none the less with a rather impressive cock. Placing one hand on the small of her back again he deftly undid his belt. At this sound she twisted her upper body and head around to look back at him and he feared that she would tell him to stop. Instead she just smiled and slowly dropped her eyes down his body before turning back around.

The button was harder to do with one hand, but needs must and it and the zip were soon navigated. He pushed the sides apart and pulled his cock out over the top of his boxers. The hand on her back came abruptly to her hip and he bent his knees and without any further warning sunk all the way into her tight heat. The both stopped and neither made a single sound. Her body was ridged and her breath was caught in her chest as his penis stretched her.

When he felt her relax and exhale he took that as his cue and his other hand mirrored the one on her hip and he pulled her impossibly tighter into his body. It only took three slow deep stroked before his willpower broke further still and his grip became punishingly tight as he pounded in and out of her willing body.

A brief flash of worry that she might not appreciate his manhandling crossed his mind before her moans of pleasure erased it. Looking down he watched his member disappearing into her body over and over again as her arsehole was presented before him. He wanted to fuck her there. It was filthy, he knew it was but he couldn't help himself, it was like once he finally let go he could feel all his wants and desires flooding out of him in one great rush. So he gathered up some of her moisture where their bodies joined before slowly sliding his thumb into her tight arse. His fingers splayed out over her cheeks and he hooked his thumb inside her. she groaned and pushed back harder against his intrusion. So she was adventurous he though and smiled.

He continued to pound into her and she met him thrust for thrust, their breathy moans and pants filled the room and sweat beaded on his forehead and upper lip.

Due to her being about a foot shorter than him he soon felt his leg start to cramp from bending his knees to plough into her. Looking around he saw his umbrella and had an inspired though. He pulled his thumb out of her arse and watched the tight ring of muscle clench back as she whimpered at the loss.

"Stay" He commanded as he pulled out of her with a wet sound and bent down to retrieve the umbrella. He motioned for her to shuffle back a step and slid the umbrella under her hips. Putting his hands at either end he hoisted her up till her upper body was resting on the back of the couch and just the tips of her toes were on the floor, then plunged back into her. The new angle caused him to go deeper and she squealed was he hit her cervix. The painful pleasure was delicious and she never wanted him to stop what he was doing in that moment.

The umbrella dug into her hips and she knew that she would have bruises tomorrow, he knew it too but neither of them cared when the pleasure of the moment was so intense, so passionate and exactly what they wanted. She arched her back and pushed up with her arms.

"Oh god please don't stop. Don't ever stop." Two more sharp thrusts were her undoing; all her muscles tensed and she went completely silent in her pleasure before collapsing limply over the back of the couch.

He let go of the umbrella and pushed her forward till her hips were high over the hard back and he was almost fucking her from above. He bent over her, curling his body along her back and she felt the wool of his suit against her body, scratchy on her sensitive skin.

When Perci had purchased the flat at 221 he had done extensive background checks on her. Her finances, her family, her career and her health records all passed over his desk. He knew that she had a clean bill of health and that she had been prescribed a contraceptive pill. This was confirmed when the other week he had used her bathroom and seen the packet with the corresponding days punched out of the foil and plastic blister pack.

The thought of cuming inside her, knowing that when she stood up his release would run think and hot down her thighs caused a tightening in his stomach. She could feel his breath hot against her neck and the shell of her ear.

"I want to cum in you. I want to pump my seed inside you. Isn't that filthy?"

"Do it… Please."

Her ready consent was his undoing and his eyes slammed shut as he spurted his ejeculate inside her body.

He held her close to him as the both panted with exertion and satisfaction. He trailed his lips and hands along her moist, hot skin, listening to her hum. Pulling out of her he felt bereft until he stepped back and watched a little of his cum trickle down her thigh and in that moment he felt shame.

He knew he had let his desire get the better of him.

Perci pushed herself up and turned to face him. One look at him and she felt desire coil in her belly again.

A man like Mr. Holmes was always polished, poised and posh. He was unflappable, dignified and genteel. He commanded the respect and admiration of others with nothing more than the slightest of actions and he seldom gave even the slightest indication of discomfort. But in that moment he had come undone… completely undone and she had caused him to do that. She did that to him and that made her feel so powerful. He had relinquished his tight control in a way that only a man with complete confidence in his own power can do.

He stood there his face flushed and his cock, still half mast, hanging between the flaps of his trousers, but otherwise he gave no indication that he had just fucked her senseless. He was still fully dressed and she felt somewhat naked with her dress still pushed up and her tights around her ankles.

"Um Yes. Right." He cleared his throat and tucked himself back in. After this was done he pulled the kerchief from his pocket and dabbed his brow and upper lip.

"Oh" Perci hurried to pull up her tights and smooth down her tunic. "Mr. Holmes, I really hope…"

He cut her off "I'm sorry. I should not have done that. Please forgive my actions they were vulgar and I should not have taken advantage of the situation."

"I'm not sorry. Mr Holmes if I wanted you to stop I would have had no compunction in asking you to do so and I have no doubt, that had I asked, you would have stopped."

He looked at her and felt his same abated slightly when I saw her kind eyes looking directly at him "Given the circumstances I really think you should call me Mycroft now."

She smiled. Stepping forward she stood on her tippy toes and kissed him. It was light at first, just a ghosting of her lips over his, but when she felt him open his mouth slightly she took it as a cue to deepen it. His hands came around and pulled her close to his body before one slid up to tangle in her thick chocolate brown hair. She moaned and he felt his penis twitch, the traitorous beast awaking again. He pulled away.

"My dear I fear that it is very late and I have a very busy day tomorrow; I should be going." She ignored him and kissed the skin just above the collar of his shirt, her tongue darting out to taste his salty skin. "if you do not stop that I will never be able to leave. I fear that I will take you again and again."

"Good" More licks and a sharp nip.

"Ms Miles please stop." She laughed.

"Ms Miles is it? I do believe that you asked me to call you Mycroft and whilst I think that that will take a little getting use to, you should probably start calling me Perci."

"Perci" Her name slipped from his honeyed lips. "Perci you must stop."

"Mr. Holm… Mycroft?"

"Yes?"

"What do you want from me?" She looked at him, her dark sea blue eyes were wide and her brows crinkled in worry. "Was this a one time thing?"

"Yes."

"Oh." She felt like her stomach had just fallen two feet.

"I never should have taken you like that Perci. It was uncouth of me and not befitting to the level of respect you deserve. I would ask if you could forgive me, if I may escort you to dinner sometime soon?"

"Oh!" Her brows shot up and her mouth formed a perfect O before breaking into a grin. Mycroft was happy for the smile as her kiss swollen lips in an O made him think lascivious thoughts. "Yes, I would like that."

"Shall I pick you up Thursday evening at seven?"

"That's a bit old fashioned don't you think?" She lilted.

"Contrary to popular belief, chivalry is not dead my dear."

"That would be lovely then."

"Right, Um I should go. I look forward to Thursday." He leant down quickly to leave a chaste kiss on her lips and almost went back for more when her tongue darted out after to wet them… to taste the essence he left behind.

"Goodnight Perci." He pulled out of her arms and retrieved his coat, umbrella and gloves from the floor. Good god he thought, he would never be able to look at his umbrella again without thinking of her wonton body bent over it as he fucked her.

When he was almost at the door she called out to him. "Mycroft?"

"Hmm"

"You will come on Thursday right?" And there she had handed all the power back to him and at the sometime trapped him completely.

"Most definitely." And with that he walked out the door. Taking the steps two at a time he smoothed a hand over his hair, slipped on his coat, buttoned it and stepped out the front door of Baker St. He turned and nodded briefly to Sherlock as he watched him out the window with a smug look before slipping into the waiting car. He had no doubt Sherlock knew exactly what he had done to the lovely Ms Persephone Miles of 221C Baker St, but found he didn't care.

Athena took hardly a moment to register his presence before looking back to her Blackberry.

"Please ensure I am free Thursday evening and book me a table for two at St John." He instructed as the car pulled away form the curb.

"Finally." Athena muttered.

"Pardon?"

"The sexual tension was driving us all mad… Sir" She added the sir to make up for the cheekiness of her comment. He just smiled.

Back in the basement flat of Baker Street Perci sat on the couch… the very same couch that the man she had spent the last five months fantasising about had just fucked her over. This revelation finally sunk in. He had taken her and she had responded with wild abandon. She shifted slightly and felt his cum and her slickness pooling in her knickers. She had always had a suspicion that the proper and polite and oh so very British Mr Holmes would be fantastically filthy in bed. Now whilst they hadn't quite made it to the bed this time, he certainly hadn't disappointed her.

Better yet she hoped that this might just be the start of a wonderful thing. Now she just had to convince him that she liked the way he lost control in the bedroom. That she wanted him to be naughty. She had seen the shame reflected in his eyes after his lapse and she knew his normal personality did not lend itself easily to flights of wild behaviour and furious fucking. She had seen a rare thing and she had every intention of seeing it again and again.

Any further thoughts were interrupted by the arrival of Sherlock.

"So you baked. I hope you didn't let my brother eat too many of those… not good for his diet." He helped himself to the cookies and poured some lukewarm tea into Mycroft's cup. Drinking it down before grimacing. "The tea is cold."

"Yes it is." She said but didn't make any move to fix him another pot. He sat in the chair and twisted the belt of his dressing gown whilst stuffing another cookie in his mouth.

"So you fucked my brother." He stated this fact around a mouthful of crumbs.

"Sherlock, you know how John has those conversations with you about the things that you say and do that are 'a bit not good'? Yeah well this is one of them."

"I don't see why. It's about time. I thought he was going to burst is he didn't get a good rodgering. Whilst you were at it did you try pulling the stick that's stuck up his arse out?"

She flushed. "Sherlock!"

He looked at her… He looked at the flat… he looked at the couch… He looked at her again.

"No I don't suppose you did… couldn't have if he still had his cloths on. "

"Sherlock, not that it is any of your business, how could you possibly know that?"

"Easy… He buttoned his coat."

"What does that have to do with anything?"

"It's a reasonably mild evening, Mycroft hardly ever buttons his coat even in the cold and only sometimes in the rain… if it's really heavy. But he buttoned it this evening most likely to cover the stain on the front of his trousers."

Her cheeks turned bright pink and he knew he was right.

"Well don't feed him too many cookies, He's getting on you know and we would hate for him to have a heart attack."

With that he stuffed the last six cookies into the dressing gown pocket "For John." He said and they both knew that John would not see a single one of those cookies.

When he was almost at the door he paused and seemed to think a moment before turing back to her… She had not moved at all from her position on the couch.

"It's true that Mycroft and I have our points of contention. We are not close, but his is my brother. Do right by the pompous git."

"I shall endeavour to try." She smiled coyly. "My very best I promise."

And with that the cookie thief bounded back to 221B and proceeded to play Puccini's O Mio Babbino Caro on his violin. He knew it was her favourite and it was his way of thanking her for the cookies without having to bow and actually say the words. The soft sounds floated in through the door that he had left open for this purpose. When the song had finished she stood and closed the door.

She looked to the table and the kusudama left unfinished there, then to the piles of wallpaper that still needed to be done and the paint and the samples and the floorboards that were still to be sanded and polished…. oh the list went on. But not tonight. She turned off the lights and wandered into the bedroom, the only room that had been finished, but was sadly filled with furniture from the other rooms still in progress. She couldn't wait for the renovations to be over.

Stripping of her clothes she slipped between the cool sheets. They would have been too cold were it not for the fact that her body was still pleasantly warm from Mycroft's ministrations. She fell asleep, his seed still sticky on her thighs and thoughts of how they came to be at this point dancing in her mind.

So that is the start. Let me know if you want to see more (although I will probably keep writing anyway it would be nice to know someone is reading)

A couple of notes from the author.

1. I don't have a beta, so I apologise for any mistakes and hope that they won't detract from your enjoyment of the story.

2. Unprotected sex- This is the world of fantasy and things like HIV and STIs don't exist and pregnancy only happens when it benefits the story arc.

3. This story will get a little bit kinky. Maybe a Holemscest threesome with Perci before Sherlock hooks up with Molly. I normally ship Molly and Sherlock when I read, but recently I have just been having cravings for Mycroft and his amazing suits.

4. For anyone who is interested Kusudama is real, google it. It's very cool, but yes very time consuming and repetitive. The documentary mentioned is called 'Between the Folds' and is absolutely amazing.
