DEAD END

Sherlock wrapped his coat securely around Molly's naked body. Holding her close he turned back the way he'd come and headed back to the relative safety of Baker Street, moving as quickly as he dared with the precious load he carried in his arms.

221B BAKER STREET

Once indoors Sherlock locked and barred the front door before he swept Molly back into his arms and strode up the stairs to his flat, slamming the door shut behind him with his foot as soon as he cleared the threshold.

He carried her down the hall and into the bathroom, placing her carefully on the vanity unit. Turning the tap he was relieved when water continued to flow. He wet a flannel then began to gently wash the grime from her skin.

He used the time to try and put some order to his chaotic thoughts. Since he'd encountered the cyborgs attacking Molly his brain had erupted with a dizzying array of thoughts and feelings, all of which had revolved around the little omega.

His omega.

He remembered his words as the final cyborg went down.

"She's my omega."

Emotions were new to him. In the past he'd always distanced himself from all notions of sentiment, preferring instead cold clinical deductive reasoning and logic. It had allowed him to stand apart from the suffocating, cloying and messy business of emotions. To him love, affection and passion were unnecessary distractions.

Then Moriarty and Moran had literally flipped a switch in his brain that had caused all that he'd held back of his alpha nature to pour freely through him.

As he finished cleaning Molly his nose twitched and he inhaled deeply. His nostrils flared as they were filled with an intoxicating scent, a musky mix of honey and cinnamon. His mouth began to water and his trousers became painfully tight.

Their eyes met, his narrowed and intent, hers wide and wanting.

Molly was trembling uncontrollably, but not with fear. She'd just gone into heat.

Sherlock's protective instincts became something far more primal. His lips pulled back baring his teeth, his breathing pattern increased and a flash of gold mixed with the blue-green of his eyes.

"Mine!" he panted, as he picked Molly up and headed to his bedroom.

Molly was in the thrall to her raging hormones never had she felt anything so intense. Though to be fair this was her first heat. She felt like she was on fire, she burned and ached to be filled and marked by an alpha. But not any alpha, the only one Molly would allow having her, the only one her body told her could truly satisfy her was currently carrying her in his strong, protective embrace.

Sherlock placed her on the edge of his bed and then stepped back to remove his coat and jacket, before he sank down on his knees to the floor where he lifted her legs and placed them over his shoulders as he lunged down to lap eagerly at her soaking, swollen cunt.

The sensation of his tongue sweeping over and through her wet folds had Molly's eyes rolling in the back of her head. When he enthusiastically sucked on her sensitive nub while he inserted first one, then two talented fingers that he used to probe her inner depths, Molly threw her head back coming hard, her legs locked around his neck, her upper body bowed back as she clutched fistfuls of his curly black hair.

No sooner had her orgasm ended than Sherlock stood to quickly remove the rest of his clothes, before he lifted and flipped her over to place her on her hands and knees.

Instinctively she widened her stance and lowered her head in submission.

Sherlock stood at the side of the bed and positioned himself at her dripping entrance. His hands pulled her buttocks back towards him. Taking himself in hand he entered her.

To immediately freeze.

As an alpha his cock was longer and wider than that of other males. He'd expected her to be tight and to meet some resistance, but he could tell by her reaction that something wasn't right.

What had he missed?

"Molly…?" he asked through gritted teeth, the need to plunge deeper into her almost overwhelming him.

Molly took a deep breath before raising her head and turning to look at him over her shoulder, her expressive eyes telling him all. Yet he needed to hear her say it.

"You mean…" he swallowed, using every bit of control he could muster to prevent his body's desperate drive that was urging him to fulfil its natural instinct. "You've never…? Ever…?"

She shook her head. "No," she finally confessed. "You're my first."

Sherlock closed his eyes and let out the breath he'd been holding. Part of him was elated. He was the only one she'd taken as a lover. He wanted to howl with triumph at the thought that she was his, and his alone.

The other part of him was terrified. She was a virgin, and for an omega she was small. He was a lot bigger than her, and an alpha. That alone would require him to take care, for it was an alphas duty and privilege to take care of his omega. Sex between the two had the potential to get rough. But on no account was an alpha to harm an omega. The fact that he now possessed cybernetic enhancements was of the gravest concern to him. Would he turn into those thugs he'd saved her from?

The risk was minimal given the fact that the second-generation cyborgs had purposefully been created sterile, and it was that modification that had been the trigger for their violent actions towards the innocent omegas.

So far there was no indication that he was sterile. That would have invalidated Moriarty and Moran's delight in activating emotions within him.

'But did he dare risk the possibility he could brutalise Molly, even if unintendedly?'

Logic was quickly overcoming his primitive alpha nature. But when he made to withdraw, Molly stopped him.

"Don't," she whispered. "Stay."

"You don't know what you're inviting," he ground out. "I'm a cyborg. The damage I could inflict on you…"

"You wont."

"How can you be so certain?"

She raised her eyes to meet his. "Because I trust you."

When he opened his mouth to object she shook her head.

"You are nothing like those that attacked me," she said. "From the moment I saw you captive in that glass cell I felt that we were connected somehow. You told that cyborg I was yours. And I am, as you are mine."

Sherlock gazed at Molly in growing wonder.

"Stop thinking and rationalising Sherlock, and instead feel. Feel what is between us and let it happen. You know we both want it and need it. So lets take what we want and we'll deal with the consequences later."

'She was a special one, his omega." Sherlock thought as he took a deep, calming breath and allowed his alpha free rein once again.

Taking a firm hold of Molly's hips he eased part way out before sliding back inside her. Having broken through her maiden barrier with his initial thrust he was careful not to cause her anymore discomfort. The exquisite feeling at her acceptance of his penetration into her body as her internal muscles enclosed tightly around his cock made him shudder in ecstasy. He leaned over her and moved his hands to cup her breasts that fit his palms perfectly.

His hips began to pump with ever increasing urgency as his knot at the base of his cock started to swell as her inner walls vibrated around him. He slammed into her again and again his thrusts becoming more forceful as his knot finally locked them together.

At that moment Molly who'd been completely submissive began to resist, as was the way of omegas. Her emotions were a mixture of willing submission and a refusal to be mastered. It was up to Sherlock to show her that he was the dominant one and to prove to her that he was an alpha worthy of her.

He reached with one hand to grasp her head and turn it so that her throat was exposed to him.

Immediately Molly's struggles ceased. She remained motionless, her breathing erratic as she waited.

Sherlock leaned forward, his nose nuzzling her throat before he bared his teeth and sank them into her willing flesh. As soon as her sweet tasting blood rushed into his mouth he lapped at the wound to seal it with his saliva.

"Mine!" he roared as Molly's body began pulsing around his cock as she climaxed. Sherlock's body moved frantically as he neared his own release, giving a shout as he ejaculated his seed into her welcoming body.

Molly collapsed exhausted and sated onto the bed.

Sherlock his feet still on the floor immediately braced his arms so that they locked, his palms pressed against the bedclothes so as to not fall and crush Molly, his bonded mate.

The position pushed his lower body further into her, causing him to experience the first in a series of smaller orgasms that would ripple through his body over the hour or so that they would remain locked together.

With great care Sherlock manoeuvred them both so that they lay on their sides on the bed.

Once his knot had eventually eased and they'd been able to separate, Sherlock and Molly finally got under the covers.

They lay facing each other, foreheads touching as they gazed into each other's eyes.

Sherlock took Molly's face in his hands as he leaned forward to press tender kisses on her forehead, cheeks, nose and lips. He then turned her head to check that his bite had healed, after which he placed a reverent kiss upon the mark that proclaimed to all that she was taken. She was his.

Molly ran her fingers through his unruly curls before pulling him close and snuggling into his warmth, a contented smile on her lips.

Sherlock gently ran his hand up and down her spine, lulling her to sleep. He fought to keep his own eyes open, there was still so much he had to figure out. But as she had when they were making their way to London, Molly's presence and touch calmed and relaxed him. And so he finally allowed himself to drift into a peaceful, restful sleep.
