Right so it seems that blackmail is the way to go in future :P I shall employ it more often. But seriously I'm so glad you liked the chapter. It's always difficult to go from nothing to smut in a small space of time (at least it is for me).

I want to give a shout out to metricjenn who got into a bit of an accident yesterday.I hope you're feeling better and I hope that this cheers you up a little xxx

Anyway, as promised and posting early. Here is the final instalment.

Chapter 3

'God, Molly you have no idea how much I want you right now.' Sherlock's words vibrated against her skin as his mouth moved back up to hers and she relished the ability to kiss him again. He was a damn good kisser for someone who she didn't think had had much practice and she wondered how he had learnt to be so good. Her whole body seemed to be on fire: she could feel every inch of him where he was pressed against her.

His hands were splayed across her naked back pulling her against him, her breasts were crushed against his shirt and she was shamelessly rubbing herself against his erection. His tongue dove into her mouth driving any other thoughts from her mind and all she wanted was for this moment to never end.

What she did know was that she wanted more of him. She wanted to see him naked, to finally feel his skin beneath her fingers and to slide down onto him. Even as they carried on kissing she moved her hands to the buttons on his shirt as she tried to work out how to undo them. Her hands were shaking as she did though and her progress was slow. In the end she felt him helping her, pulling his shirt from his trousers and undoing the final buttons and then she was pushing it off his shoulders as he pulled the sleeves down his arms.

As he moved to kiss her again her hands were greedily touching his shoulders. They were wider and stronger than she had imagined and she could feel the muscles on his upper arms reacting to her touch. She let them smooth over his chest, feeling the slight brush of hair, glad that he wasn't too hirsute. His nipples were hard as she brushed her thumbs over them. It was intoxicating being able to touch him, she wished they had more time, she wanted to see him, to learn every inch of his body but she was also desperate to feel him inside her and it was that which drove her hands on and down. They moved over his ribs before sliding down across his stomach and on to the fastenings on his trousers.

She had never moved so fast with a guy before, never even had sex on a first date but this felt different. It felt right and so natural but even so she was equally worried that she wouldn't get another chance, that he'd change his mind and she'd be back to loving him from afar. She wondered if it was the heat or the lack of air that made her feel so giddy and aroused or if it was just the final culmination of all those years of unrequited love that were now being exposed and released. Whatever it was unless he rejected her she knew they'd have sex, right here and right now.

Thankfully his hands were just as frantic as her own pulling at the zip on her work trousers, cursing when it got stuck, all the while kissing her. When she did pull back for a moment to remove her trousers and pants she giggled at how gorgeously disheveled he looked; his hair was all mussed up and his lips were red from kissing her but it was his eyes that made her swallow heavily. She had never seen such a blatant, naked look of raw desire on his face and she was in awe at how it managed to make him look even more devastatingly handsome than normal.

Finally she was naked and she moved back onto his lap and into his open embrace, smiling as he used his jacket and her trousers to protect her knees from the hard floor. It was such a sweet gesture which almost said more about his feelings than his words had. But then his hands were on her backside pulling her against him, kneading the skin with his fingers as his thumbs moved against her hips. He was holding her tight and she knew she'd be bruised but she didn't care; all of her attention was on the fact that once again his tongue was in her mouth sliding against her own making her let out moan after aching moan.

She needed more, she needed to feel him inside her and to that end she moved her hand down and inside his open pants. As she pressed her palm against him he groaned, breaking off the kiss as his head fell back against the wall and she felt his cock pulse in response. It sent an equal reaction through her own body and she felt her muscles clenching deep inside her in preparation.

She couldn't wait any longer and so she rose up on her knees giving him space so he could push his trousers down and then she was positioning him at her entrance, not wanting or needing any foreplay. She let out a breathy 'oh God' as he gradually started to fill her. It was the most amazing feeling in the world, finally being joined with him, an intimate, real connection, and she never wanted it to end.

When he was finally fully inside her she let her forehead rest against his as they both got used to the feeling. She closed her eyes and tried to regulate her breathing and her heart rate but it was no good, she could feel her orgasm was on the cusp of starting and it made her rock her hips against his feeling him hitting that spot deep within her that was guaranteed to make her come.

One of his hands was on the base of her spine pressing her onto him, making her clit press against his pubic bone as they moved together. His other was tangled in her hair which had come loose at some point. She couldn't quite remember or care when and as they started to move the only sounds in the small space were the sounds of their slight gasps and moans echoing around them.

His mouth was either on hers or on the skin just under her ear and she knew he was marking her and she wanted it, she wanted proof of this moment, she wanted to be branded as his.

She also hoped no one could hear just how vocal she was beginning to get because she was calling out his name now, begging him for more, lost in pure physical sensation and desperate for that moment when her climax would overtake her and it was so close...so, so close.

His hips were thrusting up into hers and she knew that he was near his own completion and as he cried out her name, in that oh so familiar voice, it pushed her over the edge and she came, her mind exploding as all thought disappeared.

'Oh God, oh God, Sherlock, Sherlock...ohhh...'

He was crushing her against him as he followed her over, pushing up into her as deep as he could manage, his face against her neck and his hand around her back holding her so tight as the other was braced on the floor.

Even as she started to come back to herself she could feel him still pulsing inside her and he brought his hands back to her face so they could kiss once more. This time it was less desperate, less passionate but more loving and she mirrored him placing her own hands on his cheeks. She could feel his cheekbones under her fingers and the start of a five o'clock shadow under her palms and she remembered just how hot he had looked when he had been high and she felt guilty all over again for being so damn turned on by him at such a time.

'Fuck...Molly that was even better than I had imagined it to be.'

She smiled as her eyes traveled greedily over his face trying to memorise just how he looked in this moment, wishing she had a mind palace of her own. 'So, you've been imagining it then?'

He chuckled and pressed another kiss to her lips. 'So many times this last three weeks that it's embarrassing to admit. I've imagined you in my bed, on my kitchen table, in my shower, in the morgue...'

She batted her hand against his chest and let out an admonishing 'Sherlock' but she was laughing when she did.

'I've fantasised about taking you over a desk in the lab with you wearing nothing but a lab coat and on the settee in John's flat.'

Molly felt her mouth run dry and lust starting to building again low in her stomach at all the images he was putting into her head, some she'd imagined herself and others new and surprising.

Finally he smirked and tilted his head. 'Which shall we start with first?'

She smiled shyly. 'I don't know about you but a shower sounds good. How about we go back to your place and see how it goes?'

He kissed her again, it seemed he was addicted to kissing her and Molly couldn't say she had a problem with that, it felt like an addiction to be encouraged rather than denied.

'Sounds good to me.'

Molly was reluctant to move off him but she knew she had to, grateful that she had a few tissues in her bag to help her clean up.

As she started to redress Sherlock was already standing and picking up his jacket, dusting it off; his shirt back on, but with the top two buttons tantalisingly undone, and his trousers refastened.

She nodded towards the lift controls. 'Why don't you re-buzz them? See if they're any closer to sorting the lift out.'

He moved over and pressed the button.

'Yes.'

'Hi Dan it's Sherlock we're good to go.'

'OK Mr Holmes, was it successful?'

'Yes, very much so, thanks.'

Almost immediately the lift starting moving again and Molly redoubled her efforts to button up her shirt even as she stared open mouthed at Sherlock.

'Oh my God, you planned this.'

He turned to face her and he looked neither ashamed nor concerned.

'Well of course I did. I would have thought by now that that would have been obvious. You'd refused to speak to me, you had ignored my phone calls and I'd just learnt from John that you were even considering leaving London. I had to do something.'

Molly felt sick, as though a gaping hole was opening up in her stomach.

'So what, you thought you'd seduce me in order to have me carry on working here?'

He knew immediately that he'd said something wrong and he moved forwards, his face wreathed with concern as he placed his hands on her shoulders. 'No...no of course not, that's not the reason why at all.'

She took in a juddering breath, biting on her lip but she couldn't help the worry that she still felt.

'I seduced you because I wanted to, because I do actually love you and I want you to stay. I want you to stay and live here, preferably with me, and give me a chance; just one chance Molly to prove to you how much you mean to me...please.'

He kissed her just as the doors to the lift were opening and Molly vaguely registered the gasps and titters from the staff who had been waiting for the lift but none of them made a move to enter. Instead the lift doors closed and still Sherlock kissed her even as the lift started to move back down.

Finally he pulled back smiling at her in a way that had warmth blossoming in her chest as she tentatively began to accept the truth in what he was saying.

She saw the glint in his eye as he smirked. 'I can always have the lift stopped again if I need to give you more proof.'

She chuckled and pulled him back to her. She would never get tired of kissing Sherlock and she hoped she'd have a whole life time to enjoy it. It looked like she wasn't alone, they were together at last.

And there we have it. Thanks again to Lil for the prompt, I was in the mood to write something short and smutty and she came up with the perfect idea. Last but not least, thanks to you guys for all the reviews, just one more ask, let me know if you liked it xx
