Hey, I've been a bit remiss on updating this fic. It wasn't getting much traffic or feedback so I didn't think there was much interest but it's still getting followers and I've been chivvied on tumblr so here's another instalment. I hope you like it.

I should just warn that it's totally non-canon in terms of timelines and I'm not even sure where and what season my Molly and Sherlock got together so I apologise for any inconsistencies and general weirdness :).

This prompt came from an Anon on tumblr so I hope they see it someday.

Chapter 7 - In a Swimming Pool

Since Sherlock and Molly had got together he'd been filling in some of the blanks in Molly's knowledge about his cases…not everything made it through to John's blog and not every case was written up. Both of them had always been curious about their first meeting with Moriarty but for very different reasons.

It was Molly who mentioned him first, whilst they were working together in the lab at Barts. The way she cleared her throat and her cheeks coloured alerted Sherlock to the fact that she was asking about something delicate before the words even left her mouth.

'So, that string of cases that you had a couple of years back…the ones with the bomb vests…that was all Jim…sorry, Moriarty wasn't it?'

Sherlock's nostrils flared a little at the mention of his nemesis and he felt that familiar burst of anger and jealousy that always came whenever he thought of how close that man had come to his Molly. Not that he'd ever been brave enough to ask her about him…he wasn't sure he would like or want the answer.

'Yes, yes it was.'

'But then he disappeared for a while until the whole 'fake death' thing?'

Sherlock chuckled at her underplayed reference to his two years of pretending to be dead whilst traveling the globe, risking his life trying to dismantle Moriarty's empire.

'He did, I heard he was in Italy for a while and then the South of France, I can't prove it but the activities taking place there had his mark all over them.'

'So did something happen between the two of you that I never knew about? Something that made him back off.'

As always she surprised him with her insightfulness. He pushed back his lab stool and made his way over to where she was leaning against one of the tables. They were in almost exactly the same spot as they had been when he'd first set eyes on "Jim from IT" and he wondered if that was what had brought the Consulting Criminal into Molly's mind.

He stood close, inside her personal space and placed his hands on her hips, bending his head so he could kiss her lightly. Even such a small interaction had his mind thinking of all the things they'd done and all the things he wanted to do and he pulled back before it started a chain reaction in his body, especially given it was daytime and people were in and out of this lab regularly. It was possibly the place but definitely not the time to seduce Molly.

'Yes something happened. He kidnapped John, strapped bombs to him and almost killed both of us.' He hated the way his voice quavered a little as he spoke about John. He hated remembering that night and how close John had come to death.

Molly brought her hand up to his face tracing her thumb across his cheek. 'It bothers you…that event. Do you want to talk about it?'

Sherlock shrugged, he'd never been one for therapy but he had to admit that now she had mentioned it he did feel like telling her about it…not now though, it wasn't the right time.

'Why don't I show you? We could go to the place where it all happened; tonight after your shift and when it's closed.'

The door started to open and Sherlock moved away from Molly. His parents knew about the relationship but they were still sneaking around a little, partly because it turned Molly on but also Sherlock was still nervous about her becoming a target and so he hadn't pushed the issue. As Mike Stamford walked in Sherlock gave Molly a secret smile.

'Thanks for your help Molly. I'll text you.' With that, and with his tests done he picked up his jacket and, bidding Stamford good day, he left the room.

It was eleven o'clock that evening when they finally made their way into the swimming baths that held so many memories for Sherlock. As he walked into the room holding the main pool the lighting, the atmosphere it brought it all back to him. He almost expected to see John appearing from one of the changing cubicles on the left just as he had all those years ago…or for Moriarty to come through the doors the other side of the room, his madness filling the void.

Molly slipped her hand into his and squeezed and he closed his eyes briefly bringing himself back to the present.

Slowly, gradually he talked her through the events of that evening surprising even himself when his voice broke once or twice. Looking back now he seemed so much younger, so much less jaded and full of confidence and bravado.

As he talked through the moment where he'd decided to shoot at the bomb vest, which would no doubt have killed them all he saw Molly flinch but she never said a word. He was eternally grateful that Molly accepted his need for his work and all the dangers that came with it but he had to admit that since they had got together life seemed all the more precious.

As he came to the end, making her laugh as he remembered John's comment about him undressing him and the rumours that could cause, she turned and wrapped her arms around his waist; her hands sliding under his jacket. He could feel her embrace, tight and comforting and he returned it with his cheek resting on the top of her head. She was so small and yet somehow she made him feel so safe. It felt like coming home when he was with her and he knew he'd been an idiot to resist her for so long.

As she pulled away from him she looked up and gave him what he could only describe as a wicked smile.

'Are there any cameras in here?'

He narrowed his eyes. 'No, I disabled them via my computer before we came over.'

'So, no evidence of us being here?'

He chuckled and shook his head as he raised his eyebrows. 'No, no evidence. What exactly are you thinking Miss Hooper?' He asked, knowing exactly what she was thinking and loving the idea.

'I'm thinking maybe this could count towards my list. I seem to remember sex in a hot tub/pool being on there.'

He nodded his head and looked as though he was considering the suggestion but he was getting hard just thinking about it. Maybe having sex here, in this place filled with such bad memories, would be cathartic; it would help him remember this place differently.

Even as he was thinking Molly was slowly unbuttoning his shirt. She had confessed that she loved how tight his shirts were and he had confessed that he knew that and he'd often bought and worn some just to see her reaction. She'd punched him on the arm for that one but it hadn't made it any less true. A part of him had always loved and craved the adoration that Molly had always shown him and he'd played to it more than once. It was just another piece of evidence that he was actually human with the same needs and reactions as everyone else and who doesn't like having an admirer.

She kissed his chest as her hands made their way down the shirt; pulling it from his trousers once she finished with the buttons. Her hands smoothed over the skin on his ribs before sliding down his back. He gasped a little as she pressed her body against his and he let his eyes close a little enjoying the feel of her hands and mouth on his body. He hadn't realised that he would have such an insatiable appetite for sex but he didn't think he'd ever get tired of it….and Molly was far more open to ideas and adventurous than he had ever anticipated….maybe his deductive powers were slipping in his old age.

He let his hands cup her face and he bent his head capturing her lips in a searing kiss which had her moaning and clinging on to him and he loved how responsive she was. He felt his cock pulse and harden with every noise she made and when her tongue moved against his own he found it was him groaning and desperate for more.

In one quick move he pulled her top over her head and threw it to one side before his hands moved to her back to undo her bra. His mouth was back on hers and it felt hotter and more humid in the room than it had even five minutes ago. He found he wanted to be rid of his clothes. He wanted them both naked.

Molly pushed his jacket and shirt from his shoulders, cursing when the cuffs got caught on his wrists forcing them to stop kissing whilst he dealt with them. As he did he saw Molly kicking off her shoes, her hand moving to her the fastenings on her trousers and then she was pushing them down her slim legs along with her pants until she was stood naked in front of him.

He tossed his shirt onto the growing pile of clothes and then reached for her but she ducked out of the way. He frowned in confusion as she slipped passed him but then he laughed and shied away from the splash as she jumped into the pool.

By the time her head surfaced she was grinning from ear to ear. 'Oh, this feels good. I've never done skinny dipping before but it's nice not having a costume. Come on in.'

She gave him that wicked smile again as she let herself float on her back showing off her body to him.

He didn't have to be asked twice and he rapidly removed the rest of his clothes but rather than jump in, like she had, he sat on the edge of the pool testing the water and enjoying watching Molly moving around the pool, catching glimpses of her breasts and sex through the prism of the water.

She saw him watching and waiting and she leisurely made her way over before standing just in front of him; pushing her hair back and wiping the water from her face. He licked his lips as he saw water dripping down over her hardened nipples and he was about to join her when she put a hand on his leg stopping him.

'Mmm, wait a minute.'

As she moved between his knees and put her wet hands on his thighs he knew exactly what she was intending to do and he leant back on his hands and watched as she let her tongue trail over the head of his cock. She giggled as it bounced in reaction and he gasped a little as she wrapped a slightly cold, wet hand around the base to hold it still.

Over the next minute the contrast of her cold hand and her hot mouth starting to work down his shaft sent all kinds of sensations though his body and he groaned loudly. When Molly moaned in response he felt the vibrations all the way down his erection and into his balls and it made him twitch, feeling that slow build up towards his climax starting.

He could easily have sat there all night, letting her fuck him with her beautiful mouth, but he was eager to touch her and he knew he wanted to come inside her.

She obviously felt the same because she pulled back before her actions took him over the edge and she fell backwards, letting the water support her, gesturing for him to join her. He pushed himself off the edge and into the water feeling the warmth of it envelop him and glad it wasn't one of those public pools that felt one degree above chilly.

Molly moved away from him trying to keep out of his grasp; shrieking and laughing as she splashingly half swam and half walked away from him, forcing him to plunge into the water and swim to catch her; his hand finally closing around her ankle and pulling her towards him.

She was still laughing as she wrapped her legs around his waist and her arms around his neck, the water taking her weight. He held her close and then they were kissing again. He could feel her rocking and sliding against him, using his cock to stimulate herself and he had a primal urge to just fuck her and fuck her hard. He wanted to make her scream; to feel her cunt spasm around his cock milking his orgasm from him and it made him groan.

He started to move them towards the side of the pool, so they would have some purchase, some grip for their coupling because he didn't want to wait, he wanted her now. Before they had even reached the side though Molly's hand had crept down, gripping the length of him. She lifted herself up easily and he could feel her warm and tight as she urged him to push into her. It was just like before, the difference in temperatures messing with his mind, turning him on even more.

Her back hit the tiles as he breached her entrance and slid into her and they both seemed to exhale at the connection, the kiss faltering slightly as their attention was diverted away to other parts of their anatomy. He opened his eyes and looked at Molly seeing that hers were still closed. She had a look of pure bliss on her face, a small smile playing on her lips and she looked even more beautiful than normal with her wet hair framing her face in long strands.

He pressed a kiss to the corner of her mouth and then moved his lips along her jaw as she rested her head against the edge of the pool. His movements were shallow, teasing, a slight rock of the hips a press of his hand against her backside. He knew that the slow torment would arouse her and make her climax stronger when it arrived…he'd learnt so much about her body in the last couple of months and he'd kept it all.

Her skin tasted of water and chlorine but he didn't care. He brought his other hand up to her breast toying with her breast; pinching her nipple and stroking the skin as his thrusts started to deepen. It wouldn't be long before his own need overtook him and he wanted to make sure Molly had her pleasure as well.

As he started to move faster the water lapped up around their chests splashing them occasionally and making them laugh. By now Molly's hands had left his skin and she was holding onto the wall as she braced herself against his movements, urging him on and he knew, from her cries, that she was close.

He was hanging onto his own sanity and consciousness by a thread and he kissed her throat, sucking in the skin, marking her; not caring if people saw or knew…he wanted them to know that this amazing, sensuous woman was his and his alone and that was what he told her.

'You're mine Molly…mine, and I want you to come for me, I want you to feel me fucking you and know what you're doing to me.'

He felt her muscles starting to spasm around his cock and it started a chain reaction inside him. He could feel his come rising as she cried out his name, hearing it echo around the room and then his mind blanked out. All he was aware of was the physical sensation of his climax as his seed pumped into her.

He held onto her, letting her anchor him, keeping him tethered to the earth as he rode out his orgasm.

He could feel her kissing his neck; her hands on his back, bringing him back to himself, and he moved to kiss her. It was slow and languid and familiar. He loved the taste of her, the way her lips moved against his own. She was made for him, he knew that now, and he for her.

When they stopped kissing he took a deep breath and was amused to see Molly biting her lip and looking worried. 'What? What is it?' He asked.

'Well, we've kind of messed up the pool…you know…bodily fluids and all…I didn't think of it earlier but….'

He snorted with laughter and pulled out of her at the same time, no doubt releasing those fluids into the rest of the water.

'Yes, probably a bit late to worry about that now. Seriously Molly, you're a scientist what's the dilution rate of us versus the rest of the pool? Plus there's enough chlorine in here to kill a small cow.'

She worried her lip. 'I suppose you're right…' her worry turned into a smirk, '…and it was worth it.'

'Well we can break back in whenever you want; our own personal sex pool.'

That had her giggling and he loved hearing her laugh.

They finally disentangled themselves and climbed back out of the pool. It took them five cold minutes before they found a stack of towels that they could use to dry themselves and ten minutes later they were dressed albeit with slightly damp hair.

As they exited the building Molly took his hand and leant against him smiling. 'So Mister Holmes, what's next on the list?'

Well you can't mention swimming pools to a Sherlock fan and not have them think of that pool scene with Moriarty. Although seeing Benedict wet in The Six Thatchers was damn hot!

As ever let me know what you think and if you have a prompt for the next chapter let me know that too. I'll try not to leave it so long between updates next time.
