NOTE: This is dirty. Like really, extremely dirty. I mean, I said upfront that there would be a threesome so... You are warned! If that's not your thing, then I suggest you don't read :) Enjoy!

They were kissing again.

His lips were soft, and supple, and tender, yet so aggressively hungry that Molly thought she'd pass out from the way he was snogging her. Yes, William had been incredibly flirty thus far, and of course they had exchanged a few kisses, but she certainly didn't think she'd be sprawled across the kitchen island, having the oxygen sucked out of her.

But, she wasn't complaining. His kisses were exactly what she would expect from Sherlock. Hard, and angry, and desperate, yet so knowledgeable about the way to set her body on fire.

Except she wasn't snogging Sherlock. She was snogging William. Or rather, William was snogging her. Because he was certainly in control. From the way his hands traveled up and down her skin, to his hips between her open legs, to his hot mouth…

He was most definitely calling the shots.

She couldn't help but moan into his mouth as he hauled her body up, her bum now flat on the countertop. He pressed his body into her open legs, causing her to let out a squeak at the feeling of his hard cock through his trousers. His mouth finally deserted hers, now devoting hungry kisses to her neck.

Molly shut her eyes and threw her head back, her hands holding onto the collar of William's shirt, wondering if she was going to burn in hell. What were the laws for this sort of thing? She was becoming a bloody lab experiment!

You're a part of this now. You signed your name on the dotted line, Molly.

At her tensing, William ran his nose up her neck, before pulling away to meet her gaze. His dilated blue eyes, a look she had only ever dreamed of seeing on Sherlock's face, made her gasp.

"You're thinking too hard," he told her, his voice deliciously hoarse, "Stop using your brain. Use your body."

She swallowed and couldn't help but run her hands into his hair, enjoying the feel of the soft curls between her fingers. "It's not that simple," she whispered back.

William laughed and slid his hands from her hips to her stomach, his thumbs rubbing the exposed skin of her midsection in soft circles. He moved closer and dropped his mouth to her ear, his tongue quick to dart out and lick the edge. Her soft gasp resulted in a signature Sherlock smirk on his lips.

"It definitely is, Molly. I want you. You want me. Let's indulge." His lips began a torturous descent down her neck, ending with scattered kisses across her chest and collar bone, "I'll be the best fuck of your life."

Molly let out a strained laugh, somewhere between a cry of pain and moan. "You're quite sure of yourself, aren't you?"

He just smirked, his curls falling into his eyes. "I am a genetic copy of Sherlock."

Sherlock.

She cursed and shut her eyes. How could she be doing this?

Is this even real? I'm dead, aren't I? I'm laying in the middle of Tottenham Court Road, having my eyes pecked out by a couple of pigeons. Or, Sherlock's already running an experiment on my heart and liver.

She forced her eyes open, meeting the sultry aqua stare of William. His hands had run up to her chest, and were busy rubbing the skin right below her breast. She cursed.

There was no way she could deny herself this. She was pushing her mid-thirties, desperately in love with a man who wanted little more from her than to share his outlandish stories, donate body parts, and fetch him coffee. She had risked her life and career to save his.

Could she have this one thing? Would she be taking advantage of a dear friend by shagging the brains out of his genetic clone?

She dared her eyes to dart down to the tent in his trousers. At the sight of the large bulge, she let out a defeated sigh.

Yeah. I'm going to do this. And I'm going to have a bloody good time while I do.

She moved her hands from his curls to his cheeks and pulled his face to hers, pressing a chaste kiss to his lips. With a shuttering sigh, she let the words escape her trembling lips.

"Take what you want, William. I want to cum on your cock."

Xxx

"Take what you want, William. I want to cum on your cock."

The silence of the observatory was deafening. Sherlock stared at the screen, a white-hot heat moving from his ears down the rest of his form. His hands began to shake, his breathing erratic, his eyes frantically watching the screen as William hauled Molly into his arms and pressed her lithe body into the wall.

The sound of shuffling and soft mutters distracted him from the activities on the screen. He glanced over at the trio of doctors and Mycroft, who had risen to their feet. Sherlock felt his stomach drop.

"What are you doing? Where are you doing?" He spat out, a panicking sensation taking a hold of his chest, forcing him to hold onto the table for balance.

Dr. Dawson cleared his throat, his pudgy cheeks red. "We believe that the subject and Dr. Hooper are about to engage in sexual intercourse. So, per our discussion, we will not be monitoring the activity to maintain the subject's privacy."

Mycroft couldn't help but smirk as he set a clipboard down on the table. "Please be detailed, Sherlock. Our experiment depends on you."

Before Sherlock could let out a snarky reply, the four men disappeared, leaving Sherlock alone in the cold room. He glanced down at the clipboard and began to flip through the pages. While the first points were rather rudimentary, asking for his beginning and ending heart rate, the remainder had Sherlock practically crumbling the sheet.

Duration of activity until orgasm? Number of orgasms for subject? Number of orgasms for partner?

He growled and glanced back at the screen, watching as William pulled Molly's top off, exposing her bra-covered chest to the world. At the sight of her lacy, pink number, he actually growled.

"This is ridiculous," he spat out, to no one (although his brain had inserted John into the room), "She's in love with me. Why engage in intercourse with a copy when the real one exists?"

"Because mate," Mind palace John began, his eyes playful, "You haven't exactly welcomed her affections, now have you?"

Sherlock hissed. "Get out! You're not helpful!"

He crossed his arms and looked back to the screen, his fists clenching at the sight of Molly pressing kisses down William's exposed chest. His chest tingled, as if he could almost feel the soft caresses of her lips down his body…

"Alright, Molly," He spat out, rising to his feet, "If you want to come on anyone's cock, it's going to be the real thing."

He grabbed the clipboard and disappeared down the hallway.

Xxx

Somehow, they had made their way to the sofa in the fake 221b, Molly straddling his toned body. She couldn't help but run her hands up and down his arms and chest, amazed by how Sherlock, a man who ate so little, could have such an impressive body.

Not Sherlock. This is William.

She scowled at her brain and moaned when William's lips met hers again. He had stripped her down to just her knickers and bra, himself in just the white pants he had been created in. She pulled at his curls when his lips moved down her neck to her chest, whimpering when his warm tongue dipped to the space between her breasts.

Sherlock thought they were small but William sure loves them.

Her hips began a torturous grind against his body, squealing every time her desperate center brushed against his enclosed by very engorged cock. To say that Molly was excited to see his cock was an understatement. She had dreamed of fucking Sherlock for much longer than she was proud to admit, and to finally hold his hard cock in her hand would be a dream come true.

Again, not Sherlock. This is William.

"Does that feel good, Molly?" He whispered, his voice rough, "It's going to feel a lot better when I fill you up. You want to feel your little pussy stretched apart?"

She let out a cry and grinded into him harder, her hands moving back to his soft curls. "Please. I want that!" She cried out, continuing to rock against him.

"Well, this is fun."

His voice sent chills down her spine, causing her to tense in William's arms. William wrapped his arms around her tighter and sent daggers towards the intruder.

"Sherlock. What a surprise. Can I help you?" William asked, his tone mimicking the same arrogance of Sherlock on any given day.

Sherlock watched with angry eyes, his nostrils flaring, as William continued to place soft kisses down the curve of Molly's neck. He held Sherlock's gaze, his eyes smirking at the man across from him.

"I've been sent to supervise," Sherlock barked out, taking a step towards the embracing couple, "So, I'll do my job with a front row seat."

He dropped into his chair, his eyes boring into William's identical blue gaze, unspoken words filtering through the air like dust. Molly glanced over at Sherlock, her cheeks bright red, unbelieving of the situation.

There was absolutely no way she was going to shag William as Sherlock watched. Sure, that's what she agreed to, but that was simply to protect herself—

And then William was kissing her again, and she could no longer think, the feeling of his hands and lips all over her body. She felt herself being tossed across the sofa, her knickers being ripped off in the process. She was aware of two sets of eyes staring at her, admiring her body like it was a work of art.

She had barely processed the feeling of her legs being pushed open before a warm, wet tongue had snaked between, lapping at her most personal place like a starving man. She let out a strangled cry, pulling at his curls, her body rising and falling from the surface of the sofa.

Sherlock watched from his chair, his eyes locked on Molly's still covered chest, to her toned legs, spread apart to give his genetic clone a taste. He could not tear his eyes away, nor could he stop the tightening of his trousers as he watched the ordeal.

William peeked his head out from between Molly's legs, offering Sherlock a smirk. He pressed a soft kiss to her lower lips, although his eyes were locked on his donor.

"Say, Sherlock, you see how wet she is? How ready she is for me?" He pushed one of her legs up, exposing her dewy, pink center to Sherlock's devoted gaze.

Sherlock swallowed, his eyes locked on the image in front of him. He shifted in his chair, his voice caught in his throat, as his eyes landed on Molly's lustful gaze. William had returned his mouth to her skin, his tongue pushing in and out as his thumb pressed to her clit.

As Molly let out soft gasps and moans, pulling at William's curls, Sherlock rolled up the sleeves of his shirt, refusing to look away. Finally, the ability to speak returned to his paralyzed form.

"Is that the best you got?" He found himself asking, his eyes to still locked to Molly's withering form and William's persistent tonguing.

William looked up, his thumb continuing to play with Molly's hardened nub. "We're just getting started," He replied, before returning his oral assault to her exposed skin.

Sherlock swallowed and rose to his feet, taking uncertain steps towards the couple. "That's a weak excuse for an ill-performed job. Why hasn't she orgasmed yet?" He barked out, his hands shaking.

Molly swallowed and met his gaze, letting out another hoarse cry at the sight of Sherlock's fiery eyes and the feel of William's unrelenting tongue between her legs. She made another desperate pull at his curls, continuing to watch Sherlock, her mouth agape.

"Oh god," She gasped out, her legs wiggling, "I must be dreaming. This isn't happening."

Sherlock scoffed. "Oh, my Molly," he whispered, leaning forward to run his hand down her smooth stomach, "If you were dreaming, I presume that William would have gotten you to orgasm by now."

William growled and gazed up at Sherlock, his eyes issuing a challenge. "If I can't do it, what makes you certain you can?"

With a snort, Sherlock dropped to the ground, leaning over the sofa with a determined look across his face. "Simple. I'm me. While you will exceed the skill and intelligence of an average man, that will not be the case when put next to me. I am your superior in everything."

A taunting smile grew on William's lips. He rose from the sofa and stared at his donor.

"Prove it."

Molly looked between the men, her eyes hazy, her entire body humming. Deciding that she couldn't wait, she slid her hand down to her spread legs, and began to touch the sensitive skin. When she let out a soft cry, both men immediately turned to look at her.

The sight of two Sherlocks, two heads full of dark curly hair and bright blue eyes, staring back at her, caused another desperate cry to escape her lips. William smirked and leaned over, capturing her lips with his own. Molly moaned into his mouth, pulling at the curls, inexplicably turned on by the taste of herself in his mouth.

And then, she felt a sensation so surreal, so impossible, that she was immediately convinced she was either dreaming or dead. Because, as William pressed soft kisses to her chest, another curly head was buried between her legs, lapping at her core like a parched man in the middle of the desert.

"Sherlock!" She practically sobbed out, quick to reach down and grab a handful of curly hair, "Oh my god," she continued to cry out.

William just chuckled and forced her bra down her body, capturing a pink nipple between his lips. Sherlock, meanwhile, continued his oral assault, his tongue and fingers working in a desperate fury. He pushed her legs further apart and pushed a finger inside.

"Oh, fuck," she cried out, forcing her eyes open to gaze down her body.

And at the sight of two mischievous sets of blue eyes staring back at her, she let out a hoarse scream, her body shaking as her orgasm hit her. Sherlock continued to rub at her clit with one hand, two fingers on his other hand moving in and out of her clenching form.

William kissed back up to capture her lips, his hands holding her perfectly sized chest, as his fingers flicking and pulling at the erect nipples. As her convulsions stopped, she let out another cry and collapsed onto the sofa, staring at the two sets of blue eyes.

"That's how you make a woman orgasm," Sherlock explained, his fingers still rubbing gently at Molly's aroused core, "Although, I don't blame you for failing. You're young."

"But eager," William retorted, rising to his feet.

Molly whimpered, staring at William's tented pants, the hardened cock at her eye level. She gazed over to Sherlock, who was watching her. Moving her hands to her sides, she forced herself to sit up, her gaze shifting between the two men—a practically naked William, and an entirely clothed Sherlock.

"Jesus," She whispered, immediately swallowing any disbelief in her situation. She simply crawled towards Sherlock and began to unbutton his shirt.

He watched her with unreadable eyes. "Molly…"

"Shh." Was all she offered, before pushing the top down his shoulders. She made quick work of his belt and trousers, until he stood wearing just a pair of black, silk pants.

She looked back to the white-panted William, and the black-panted Sherlock, both shirtless and clearly aroused. She swallowed again and rose to her feet, her gaze continuously moving between the men.

"I have to be dead. Or dreaming. Or reading a really raunchy romance novel," she managed out, her hands practically shaking.

William smirked and took a step forward, running his hand down Molly's cheek. "You're awake, Molly. And we can continue our fun. With Sherlock, if he so pleases."

Molly swallowed and glanced over at Sherlock, who was intently watching her interact with his genetic copy. She took a shaky breath and bit her lip. "Sherlock, you don't have—"

Sherlock took a step forward, his eyes locked on her chocolate orbs. "If you're going to cum on anyone's cock, it's going to be mine."

The noise she let out was somewhere between a squeak and a sob. Unwilling to even consider his words, she shut her eyes and just let sensation take over.

Yup. Definitely dead.

When a soft pair of lips met her mouth, she immediately knew it was Sherlock. His touch was gentle, attentive, and lit every inch of her body on fire. He pushed his tongue into her mouth and she let out a pathetic moan, moving closer to his hardened body. William, meanwhile, had pressed against Molly's back, and had one hand toying with her breasts, the other back between her legs.

The intense kiss continued, weakening Molly's legs by the second. Her hands slid down to Sherlock's bare chest while his had migrated up to her face, cupping her cheeks in a far too intimate way for their current setting. William began to trail kisses down her exposed neck and his hands continued their palming of her perfect chest.

"How does this feel, Molly?" William whispered, his fingers pinching and twisting her delicate nipples, causing her to cry out into her kiss.

Molly whimpered and pulled away from Sherlock's kiss, forcing herself to meet his intense gaze. His dark blue eyes were just as dilated as her own. She was absolutely paralyzed. She could do nothing but stare at him, listening to William's filthy words.

"You want to fuck both of us?" He asked, one hand now traveling down her stomach to rest between her legs, "You want to suck my cock while Sherlock fucks you?"

His words caused her to shake, her legs almost giving out at his question. Sherlock kept his eyes locked on hers, his face as always, telling her nothing. When William began to press more kisses down her neck, she felt a burst of confidence.

With a deep breath, she spread her arms, pushing one hand behind her to rest on William's thigh, the other to in front of her, where it rested on Sherlock's stomach. She met his aqua gaze again, before squeezing his length through the barrier of the fabric. She did the same to the man behind her, letting out a soft moan at their purrs of pleasure.

Deep breathes, Molly. This is like Uni, right?

She let out a pathetic laugh and threw her head back, resting it on William's shoulder. Then, with the flexibility of someone ten years younger than herself, she began to push both of their pants down, a shy smile across her lips.

Not like Uni. At least not like your Uni experience.

She stepped away from the men, giving her a chance to admire their forms. Their perfectly shaped, perfectly toned, very identical forms. And again, the sight of two curly-haired devils with bright blue eyes staring back at her made her almost orgasm on the spot.

They caged her in, forcing her to breath in only their deliciously spicy scent. She let her eyes gaze between the two, lost in the haughty grin of William, and the stone-cold expression painted across Sherlock's face. With one last swallow, she reached her hands forward and grabbed both of their cocks.

How is it possible for him to be so perfect?

And perfect he was. Or, rather, they were. She had spent an embarrassingly long period of time fantasizing about Sherlock's cock, wondering how thick he was and what he'd feel like filling her up. And just like a dream, she was staring at the most beautiful dick she had ever seen.

Multiply that by two.

She wrapped her hands around both of their shafts, giving the heated skin a squeeze. She swallowed and took a deep breath, willing herself to be the bold, sexy woman she had always wanted to be. Deciding that she enjoyed making Sherlock angry, she leaned over and gave William a kiss, beginning to move both of her hands in a steady stroking motion.

William groaned and immediately returned her kiss with enthusiasm. He ran a hand through her hair and used his other to grip her chin, pulling her face even closer to his own. Sherlock watched the two with hazy eyes. He put his hand over Molly's, joining her stroking of his member.

He leaned forward and pressed his mouth to her hair, his lips hovering over her ear. "You never answered William," He whispered, his voice plastering goose bumps across her body, "Shall I fuck you while you suck his cock?"

His hands ran to the front of her body, capturing her breasts. He kissed the top of her head, watching as she pulled away from William's kiss. When their eyes met, Sherlock couldn't help but smirk.

He's going to kill me. They're going to kill me. Unless I'm already dead. That's possible too.

Molly looked between both men and swallowed. She knew what she wanted. She knew what they wanted. And by god, she was most certainly ready. She looked back to Sherlock, the man she had loved for years upon years, and gave him a sexiest smile she could muster.

"I was promised cumming on someone's cock," She replied, nibbling on her lip, "I'm getting antsy."

She gave both of their cocks another ambitious squeeze. "Someone better fuck me or I'll do it myself."

Sherlock looked over to William, who just watched him with mischievous eyes. He growled and took a step forward. "On the sofa" He barked.

Molly nodded quickly and dropped to the surface, her hands rubbing nervously along her thighs. Sherlock settled between her legs, pulling them into the air, exposing her wet center to the cool air. She let out a soft cry as his thumb pressed against her clit.

"I'm going to fuck you now. And then you're going to cum on my cock. Do we have an understanding, Molly?" He whispered, his fingers now dipping in and out of her wet heat.

She let out a desperate cry and nodded, her eyes flicking between Sherlock's aroused gaze and William's amused eyes. And then, giving her only a chance for one deep breath, Sherlock pushed into her, filling her inch by glorious inch.

Oxygen escaped her. The feeling of Sherlock inside her was indescribable. It was something she imagined only happened in films. William nudged forward and brushed some of her hair back from her face, grinning. Then, with little grace, he pushed his cock towards her mouth. She immediately invited it inside, moaning onto the thick appendage as Sherlock began to move.

A film? More like a bloody porno, Molly.

She wrapped her hand around William's cock and groaned as it was pushed deeper into her mouth. She met his gaze, gasping at the intensity shining through. Sherlock's grunts were music to her ears, his fingers continuing to dig into her hips, his own roughly pounding against her.

Because that's what his fucking was like. Delicious, glorious, savage smacks of skin upon skin. His cock continued to pummel in and out of her lithe frame, her legs wrapping around his waist in a chokehold so deliriously intimate that it made her woozy.

She moaned onto William's cock, her tongue dancing around the head, her eyes now watching Sherlock's movements. He met her gaze and growled, his eyes shifting between her chocolate orbs and the actions of her strawberry lips. He moved a hand to the crevice between her legs and began to rub her clit.

"Oh, Molly," He hissed out, his hips continuing their fierce movements, his thumb working aggressively at her nub, "You are marvelous."

William groaned and ran his fingers through her hair. He looked towards Sherlock and smirked, before back to Molly. "Indeed, you are, Dr. Hooper. You look fucking edible with my cock down your throat."

He pulled her by her hair, forcing her to meet his gaze. She groaned onto his cock and continued to suck, her tongue dancing around the hardened skin. He let out a low growl, mimicking Sherlock's previous noises.

"You like this, don't you? You like being fucked by two of us," He tugged at her hair again before letting go, watching with glee as she pulled away momentarily, coughing when his thick shift escaped her lips and danced in front of her.

She wet her lips and wrapped her hand around him, beginning to stroke the velvet skin. She met his gaze and let out a squeal as Sherlock captured one of her nipples between his lips.

"Yes," She gasped out, her second hand joining her first, her eyes locked on William's blue gaze, "I like fucking both of you."

Sherlock grunted and hauled her body into his arms, taking only a moment to flip her over, forcing her on her hands and knees, her backside exposed to his hungry gaze. He ran his thumb down her drenched slit, before once again pushing inside of her. She let out another desperate cry and welcomed William's waiting cock back between his lips.

William smirked and tugged at her hair once again. He made eye contact with Sherlock before looking down at Molly, who continued happily lapping away at his cock. He groaned and pulled at one of her nipples, enchanted by the minx in front of him.

"You're naughty, Dr. Hooper," He moaned out, his hands now playing with perfectly-sized chest, "And I can't wait to watch you cum on Sherlock's cock. Will you do that for me?"

He pressed a chaste kiss to her head, watching as Sherlock slid his hand between her legs, once again rubbing her delicate skin as he fucked her. Sherlock began to move faster, his movements growing erratic as his orgasm neared him.

"That's it, Molly," William cooed, pulling at her hair as she let out a desperate cry, her body thrashing backwards against Sherlock.

She pulled away from William and dropped her head, letting out a throaty scream as her orgasm pierced through her. Her body was momentarily paralyzed as her body shook from the unfamiliar pleasure. She let out another hoarse sob as Sherlock's movements quickened, his breath hitching in his throat.

She reached forward and accepted William's cock once more, taking the shaft with a renewed enthusiasm. With only a few moments more, Sherlock let out a guttural cry and pulled out of her body, exploding onto her back with a passionate curse.

Molly moaned at the feeling and met William's gaze, her eyes playful. She hiccupped and released him, moving to her feet. She turned to Sherlock and smiled softly, her heart beating hard from her previous orgasm and his look of admiration. She wrapped her hand around William's cock, and did the same to Sherlock's deflating shaft.

"Your turn," She whispered to William, her eyes dancing in the light.

William growled and dropped to the sofa, moving Molly onto his lap. He pressed his face into her hair and lowered her onto his cock, letting out an expletive as he entered her warmth. Molly moaned and watched as Sherlock approached her.

As William helped her move up and down, Sherlock pressed a soft kiss to her lips. He sat beside the couple on the sofa and began to gently caress her chest with one hand, the other moving to her face to cradle her cheek.

Molly whimpered and deepened the kiss, bringing a hand to pull at his soft curls. She pushed her feet into the sofa, desperate for balance as she met every one of William's eager thrusts. And between Sherlock's sensual kisses, and William's enthusiastic driving of his hips, she was already close to another orgasm.

I'm in heaven. I must be.

Sherlock kissed down her neck to her chest and captured a dusty pink nipple between his lips. At the same time, one of his hands slid down to her stomach, beginning to again play with her excited nub of pleasure. He met her gaze and grunted.

"Sherlock…" She moaned out, her eyes dropping to his already hardening cock, "Let me taste you. Please."

He moaned and rose to his feet, immediately cursing as Molly's warm mouth enveloped his cock. She began to eagerly swallow the shaft, squealing onto the skin at every one of William's thrusts. William groaned and kissed her jaw, quickening his pace.

"That's it, Molly. Be a good girl and suck his cock. Make Sherlock feel good again. Then we'll make you feel good," William hissed out, his tongue running down the damp skin of her collarbone.

Molly gasped onto Sherlock's cock and continued to move her hips, her eyes rolling to the back of her head. Her body was working on muscle memory, devoted only to making the two men feel good. Her brain was no longer functioning. It was controlled only by the promise of pleasure.

Sherlock growled and pushed into her mouth, continuing to watch her delicious lips stretch to accommodate his girth. He tilted his head back and let out a throaty moan, knowing he was already close to another orgasm.

And then, one after another, their climaxes descended. Molly let out an erotic scream, her head falling back to rest on William's shoulder. The delicious tightening and spasms of her cunt pulled William over the edge, causing him to let out a raw cry, his body shaking from the sensation.

The image was too much for Sherlock, who let out a frantic howl. His cock bounced excitedly, covering Molly's chest in a scene so lewd that the view would forever be engrained in his mind palace, buried away in a section labeled for only the loneliest of evenings.

Sherlock collapsed back on the sofa, joining the other two in a jumble of sweaty skin, limbs, and labored breaths. Molly let out another content moan and ran her hand through her hair, her fingers jerking as they hit each and every knot.

William just hummed in satisfaction, a grin splayed across his lips. "Well," he began, his eyes glancing over to Sherlock, "I reckon you did much more than supervise."

Sherlock rolled his eyes and looked to Molly. When she met his gaze, she blushed and moved off William, moaning softly as the sticky fluids began to run down her thighs. She settled between both men, her body continuing to hum in absolute satisfaction.

"If I was going to share her, it was going to be with myself," Sherlock began, his hand moving between her legs to gently rub at the sensitive skin, uncaring of the mess, "I dare say we did well."

Molly let out a soft moan and nodded, glancing between the two men, "That was… I've never…"

Instead of finishing, she just let out another moan and rested her head on Sherlock's shoulder, content on simply basking in the afterglow. William smirked and kissed her head.

"Speechless, is she? Then we have a job well done."

Sherlock couldn't help but chuckle. He rose to his feet, lifting Molly into his arms. "I'm going to help her wash up," He pointed to the clipboard he had discarded upon entering the room, "Now, since you're so clever, fill out that information."

He shuffled down the hall and into the bathroom, setting Molly down on the sink's counter. He turned the water on and turned to look at her. She bit her lip and looked down.

"Molly. There's no need to be shy. I would say we're far pass that now, wouldn't you agree?"

She blushed and nodded. "Right. It's just… That was…"

"I'm aware. So, you've said. I'm sure you have many questions."

She cleared her throat. "Many. Was this just…"

"No." He quickly jumped in, his eyes darting away before back to her eyes, "I realized recently that I care about you. Very much so. And very much in a non-friend way."

"Oh?" She whispered, leaning forward to wrap her arms around his neck, "Then how so?"

He swallowed and met her gaze, "In a manner that would allow us to have intercourse again. And watch crappy telly together. And perhaps one that would see you moving into Baker Street."

She grinned and gave him a chaste kiss, her eyes sparkling. "I would love that," she whispered, "You know how I feel about you."

He tensed and couldn't help but look down. "Yes. I'm afraid I needed William's presence to help me realize how I felt."

"That's okay," She began, "I enjoyed his presence too."

Sherlock couldn't help but laugh. He lowered her into the bath and smiled. "That was rather…"

"Dirty." She finished for him, her cheeks bright red.

He coughed and nodded, beginning to cover her body in sudsy water, "Quite pornographic."

"Let's do it again."

Sherlock blinked and met her chocolate eyes. He swallowed and nodded.

"Yes. I think I'd like that very much."

Xxx

Approximately two weeks later, Molly was led back to the examination room, her body deliciously sore from another explicit evening between herself, Sherlock, and William. The past weeks had been incredibly naughty—the days began with the standard experiments and tests, and they ended with sordid nights of pleasure across every inch of the fake 221b.

But, the two weeks had come to an end, and Molly needed to return to the real world. Sherlock, in addition, had a mission to complete. He had a whistleblower to track down, and a mystery to be solved.

She strolled into the white room and looked to William, who was currently running on a treadmill. Sticking to the very creepy, very sterile, sci-fi theme, the poor man was clad in all white attire. Molly couldn't help but admire the way his muscles flexed as he ran, reminding her of the previous evening.

She let out a shiver of delight as she recalled riding Sherlock unabashedly when William lowered himself and began to lick at her oversensitive core. She bit her lip, desperate not to moan as the other man came up behind her, placing his hand on the small of her back.

"How is he looking?" Sherlock asked, watching as William's speed was turned up.

Mycroft walked over, Dr. Dawson to his left. The pudgy man grinned.

"Oh, he looks incredible! At the two-week mark, Subject 35 had a notorious decline in health. Subject 36 however, is still at his peak. We look forward to more time with him."

Sherlock nodded and pulled Molly closer. "We would like to visit him. Treat him well or I will know."

Dr. Dawson nodded. "Of course. We have many tests in store. He's in capable hands."

He strolled off, leaving Sherlock, Molly, and Mycroft. Sherlock turned to his brother.

"I presume you have a plan in order."

Mycroft gave him a curt nod. "Indeed. Should he… surpass the five-week mark, we will begin training."

Molly blinked and looked between the two men. "Training? What are you talking about?"

"You're smart, Dr. Hooper. You know precisely what we're referring to," Mycroft responded, looking positively bored.

She sighed. "Great. You're going to send him off to save the bloody world too, aren't you?"

Sherlock grinned. "Is that what I do? Save the world?"

She hit his chest. "I'm just trying to keep his best interest at heart. This is all unchartered territory."

"As we're aware, Dr. Hooper," Mycroft began, "We are monitoring him closely. We will do what is best."

He disappeared out the room. Molly looked to Sherlock and couldn't help but smile.

"Well, this has been an interesting two weeks. And now I'm fifty thousand pounds richer." She couldn't help the delighted tone to her voice.

Sherlock smiled in return. "Yes. It has been. Will you accompany me back to Baker Street? We have a lot to discuss. And I want to show you something."

Molly nodded and gazed back to William, who was still running. He met her gaze and grinned, offering her a wink. She laughed and blew him a kiss. Sherlock gave the man a curt nod, before steering her out of the room.

"I really grew to care for him," She added softly, as they were ushered into the town car.

"As did I," Sherlock admitted with a sigh, "But, we will have the opportunity to see him again in the future."

Molly nodded and gazed out the window, watching the landscape as the car drove on. She bit her lip and turned back to Sherlock.

"What if he lives indefinitely? Then what?"

Sherlock considered her question. "I don't know, Molly. But, I suppose the world could use another me."

She couldn't help but snort. "That's debatable."

He scowled, before she settled his features with a quick kiss.

Later that evening, Sherlock and Molly sat on the sofa, feasting on Thai takeaway. They were happy to be back at the real Baker Street, even if the replica had felt rather homely. Sherlock was enjoying his final evening before being whisked away with his next task, knowing he'd be gone for more than a few weeks.

Molly leaned against him, resting her head on his shoulder. She sighed.

"We finally get somewhere and now you're leaving," She whispered, a playful pout spreading across her lips.

Sherlock nodded and sat up, ignoring Molly's protests as he stood up. He just smirked.

"I'm aware the timing is awful. But I do have a parting gift."

He disappeared out of the room, leaving Molly to spread out across the sofa, letting out a groan. She immediately perked back up as he entered the room, holding a laptop she didn't recognize. She raised an eyebrow.

"That's new. Where did you get that?"

"Mycroft. It's not important. What I have on it, however, is."

He rejoined her on the sofa and began clicking through files, until a video started. He fast-forwarded until a familiar scene began to play, causing Molly to let out a surprised gasp and perk up in her seat. She looked over to Sherlock, her mouth agape.

"How did you…?"

He smirked. "Everything was on tape, as we know. So, before destroying the files of our… nightly activities, I may have kept them all. For future enjoyment."

Molly let out a soft moan and looked to the screen, shivering at the sight of her using her mouth on two deliciously hard cocks. Her body was immediately craving the attention of the two men she had shared for almost two full weeks.

Great. They've ruined sex for you.

And so, a little while later, Molly and Sherlock had sprawled across the sofa, lit candles (Molly insisted) surrounding the coffee table. The laptop was playing a particularly carnal evening from the previous week, allowing the couple to enjoy the delicious activity.

They had snogged a bit before falling asleep (evidently two weeks of extremely vigorous sex will do that), the video continuing to play. Content in each other's arms, they didn't stir as the front door opened, and an irritated John Watson strolled into the flat.

"I had to find out from Mycroft—" He immediately stopped speaking as his eyes landed on the embracing Molly and Sherlock. He couldn't help but smile, happy to see his friends finally finding happiness.

As he turned to leave, interesting noises from the computer, namely a feminine squeal and a masculine grunt, stopped him in his tracks. His curiosity won over as he approached the sofa, leaning over to laptop.

He couldn't help but laugh as his eyes landed on the video, watching as a petite woman was taken from behind, her mouth wrapped around another bloke's cock.

Interesting. They're already watching porn together.

He laughed again and turned to leave, until a very Sherlock noise caught his attention. He blinked a few times and returned his attention to the screen, quite literally almost falling over as realization hit him. That petite woman was Molly, and she was rather enjoying the attention of Sherlock and…

THE CLONE?!

His mouth dropped open and his eyes remained plastered to the screen, embarrassed to admit that he could not look away.

"Do you like what you see?" Sherlock's deep voice had John falling over, landing with a groan on the carpet. He looked towards the curly-haired detective, who remained on the sofa, his eyes shut.

"I… I…"

Even with his eyes closed, he smirked. "You discovered our little secret, John."

John sputtered and pulled at his collar. "Well I—"

"Mhm. Maybe I'll let you borrow the video sometime."

John blinked and turned red. "I don't—"

Molly's voice both had them turning to the woman in surprise. As she opened her eyes, she bit her lip and flushed red. "Or maybe play your cards right and you'll be number three next time."

John opened his mouth, but closed it once he realized that no words would come out. He cleared his throat, offered the couple a curt nod, and raced out the door.

She just laughed and snuggled into Sherlock. He watched her with curious eyes.

"My god, Molly. Have you become sexually adventurous in the past fortnight?"

She smirked and kissed him softly, her eyes mischievous. "Maybe William rubbed off on me."

"But John?"

She shrugged and straddled him, her hands moving to play with the lapels of his dressing gown. She kissed him again and smiled.

"Might be a fun experiment."

Sherlock let out a choked noise before kissing her again.

Back at the lab, Mycroft closed the folder and looked towards Dr. Dawson. He checked his watch for the third time.

"So, to put it succinctly, yes, we can genetically modify any of our reproductive clones. Just as you requested that Subject 36 lack self-control and have a healthy sex drive, we could do similar changes with future subjects."

Mycroft smirked and nodded, before rising to his feet. "I'm glad this experiment was a success. In more regards than just the science."

Dr. Dawson gave the man a curious gaze. "I'm not sure I follow."

"I wanted to teach my brother a lesson, Dr. Dawson. I do believe that was accomplished."

Dr. Dawson nodded, although still appeared confused. "I meant to inform you. Some of our cameras and system files failed. We're missing most footage from the flat during the evening."

Mycroft smirked. "I'm aware. I let Sherlock tamper with the system."

The pudgy man sputtered. "But—that was—you can't—"

"Believe me," Mycroft began, heading towards the door, "There are some things that should not be seen."

My dearest brother, however, would disagree.

The End

…Maybe
