Ok. This story was supposed to be some senseless smutt-oneshot. But then suddenly a REAL story formed around it - which made me decide to publish it. It's rated M for a good reason.....I'm currently working on chapter 4, so there is plenty more to come soon - if you like it, let me know. Endless thanks to Sandy who is a REALLY great and fast beta-reader. Oh and I still don't own Castle. If I did, some of that story would happen soon.... well, girl can dream, right??

Chapter One.

She got home – finally. They had a warehouse building under continuous surveillance and one of the Detectives had to be there always – so Ryan, Esposito and she had to take turns. Her shift had now ended – it was 5AM but she did not feel like sleeping at all. She closed her apartment door behind her and sighed. She hadn't seen her boyfriend for what now? Three days? That was quite a long time – ever since they got together, they spent much time together – either he was shadowing her at work at least half a day or they spent their evenings or nights together. She missed him already now – and she missed the incredibly good sex. She giggled, it was ridiculous. She had been without for months before she finally hooked up with him – now it seemed she couldn't do without for 3 days?

She went further into the apartment and suddenly saw a phone and a wallet lying on her kitchen table, a jacket hung over a chair next to it. Her heart skipped a beat and then started beating faster. He was here. She listened closely but heard no sound at all. She went directly into her bedroom, and there he was – fast asleep.

She closed the door behind her and in the dark quickly stripped out of all her clothes. The she paused, checking the clock again. She really needed him now, she was far too agitated to sleep – she knew exactly what she needed to relax. But was it fair to wake him up just so she could have her quick release? Oh well, he was here, wasn't he? He probably came here for exactly that reason but when it got too late, he had just gone to sleep.

She slipped under the covers with a fluid motion and slowly crawled near him. He lay on his side, back to her. She briefly shut her eyes as she snuggled up closely behind him, bringing her naked body up to his, feeling his warm skin on hers that was considerably colder. She lay there for some seconds, but then sighed because like she had thought before, she felt completely awake. And still in need of some good sex.

She started kissing his neck and brushed her hand down his chest, over his stomach and then directly into his boxers. She felt him flinch as he awoke and kept kissing his neck and shoulders while she felt him harden in her hand.

He slowly started turning towards her, opening his eyes while he did and grinning at her.

"Hey. What are YOU up to in the middle of the night??"

She just leaned in and gave him a passionate kiss, hoping that he wouldn't need further explanation. He joined in willingly and pulled her as close as possible. Just as she thought he had taken the hint he broke the kiss and leaned back a bit. His grin was now downright nasty, she could see the sparkling in his eyes even in the dark of the bedroom – he was up to something.

"No SERIOUSLY, what's going on?" he said with a sweet voice, mocking her.

She rolled her eyes in frustration – most of the time she enjoyed it by now if he was being playful – even in bed. But not today! All she needed was….

"Castle!! What do you THINK? I wanted to wake you to say you could sleep some more hours??"

He laughed at that and with a sudden move rolled her on her back, pressing her down with his weight and kissing her some more, then moving his mouth over along her jaw line to whisper in her ear:

"Well, I see it that way. You made me wake up so you can have your nasty little way with me. So before you get what you want, it's me who is going to get something. Beg for it."

Heat rushed through her, followed by disbelief. Did she hear that right? He wanted her to…

"What?"

He chuckled and kept pressing kisses to the side of her neck and that sensitive spot behind her earlobe, which sent tiny shock waves through her constantly.

"You've heard it right – beg for it and you are going to get it."

At that moment she hated her body for betraying her – she wasn't going to beg for it, no way! But she felt her pride slipping away fast as he started kissing a slow trail down her body, sucking and biting on her already erect nipples while disposing of his boxers. He came back up to face her and still had that devilish smile on his face.

"So? I'm waiting." He stated and shifted his hips so she could feel his hardness between her legs. She let out a frustrated moan and tried half heartedly to shove him away as long as her pride still allowed it. She WASN'T going to beg…

He grabbed her wrists and held them down next to her head, leaning in and involving her in another kiss until she stopped struggling. She gave up easily though and couldn't even bring herself around to really fight him off – God knew if she wanted to get REALLY rid of him she would. She closed her eyes and sighed.

"Please.." she said in a low voice.

He looked at her with mock surprise.

"What was that? I'm not sure if I heard that right?"

Frustration and anger started to rise in her and she prepared to swear heavily at him – at that precise moment he drove into her hard, cutting of her angry rantings before they could escape her throat, making room for a loud moan.

The second he pulled out again, she groaned in frustration, her pride now fully absent. She NEEDED this now no matter what.

"Please. Don't stop. Just keep going. PLEASE!" she was a little shocked herself how desperate she sounded. This time he seemed to really get it, for he let go of her wrists and started to move inside of her again with deep and long thrusts. She moaned and closed her eyes, feeling her whole body lighting up with desire, quickly being driven towards the edge. She internally prayed that he would keep going like that; she dug her fingers into his ass and pressed him down to indicate that she needed more.

"So. Good. Please. More." She uttered, her mind now on autopilot and not caring at all anymore if she sounded needy and desperate – hell she WAS!

He picked up his speed some more and finally she felt her sweet release nearing and didn't fight it back – she just let it wash over her, her whole body clenching to him desperately. His movement gradually slowed down, she felt the excitement and stress of her day fall off, making room for blissful weariness and relaxation. He was kissing her softly now, rolling off her and taking her with him. She snuggled up to his side and sighed.

"See, that wasn't half bad – I knew you could do it."

She thought about pinching or hitting him for the comment but she already was drifting off to a peaceful sleep. So she just made an undefined noise and smiled to herself. He hadn't had the last of that. Enjoy the silence Castle, she thought. The storm is already gathering.
