Apologies for the long wait for this chapter. I'm in the middle of exams so life is a little hectic but I'll do my best to update you with another chapter by the end of next week.

Kate was sitting curled up in Castle's lap as he pulled his fingers gently through her damp hair. She was dressed in a pair of his sweatpants and one of his old jumpers that was far too big for her.

'What time will Alexis be home tomorrow?' she yawned, snuggling further into Castle's side.

'Around eleven I think. Hopefully, if she takes it well, we could all go for brunch?' He asked her. Kate lifted herself up, still wincing, despite the hot bath. She stayed as close to him as possible but raised her head so she could look into his eyes.

'Mmm sounds good,' she replied. He watched her think deeply as she reached up to chew on her thumb nail again.

'What's wrong Kate,' he frowned at her. 'I thought you said you wanted to tell her?' He questioned, confused. She sighed deeply, not quite meeting his eyes.

'Oh Rick I do. She deserves to know, she's your daughter and I don't want to keep things from her,' She replied.

'Then what?' he asked, still confused.

'I think she hates me,' she said in a tiny voice, looking down at her lap. Castle sat up straighter, turning to face her, his face etched with worry. He lifted her chin so she would look at him.

'Why do you think that? She looks up to you Kate,' he told her.

'Not anymore Rick. She blames me, for everything. I take you away from her, and I put you in danger and to be honest I don't blame her and after the whole bank robbery thing...' She rambled on.

'What bank robbery thing?' he asked. She didn't answer, just turned away, embarrassed. 'Kate,' he pressed. She sighed again and looked up at him.

'Alexis may have yelled at me that day. She got really mad and told me I better get you out safely,' she told him.

'Sorry, my daughter, yelled?' he asked disbelieving.

'It was the stress Castle. She was worried sick, you and Martha were in there, you're all she has. God, I was almost having a breakdown, I can't imagine what she must have been feeling,' Kate shared with him. 'And we haven't really had a chance to talk much after that, apart from having quick interactions at crime scenes or her overhearing us argue about your sex life at the morgue.' She looked up at him and raised an eyebrow.

'Look Kate, she's older now, she understands that this,' he said gesturing between them, 'is different. We're not just fooling around and she's going to have to respect us.' He told her firmly.

'I don't want to come between you and I don't want to be at war with her either,' she stated.

'You won't be,' he said leaning in to place a chaste kiss on her forehead. 'We're going to talk to her, together and she's going to accept it. Who knows, she might be completely fine with it.' He smiled at her. She still looked worried so he placed a bruising kiss against her lips and gently pushed her down onto the couch. 'But for now, I don't particularly want to be thinking about my daughter when I do this to you,' he smirked up at her.

'Do what?' she said with a shaky voice as his hands wandered all over her body.

'This,' he said as his hand quickly slipped inside his sweats and then inside her panties and finally deep into her. She gasped and rocked her hips up towards his hand.

'You, Richard Castle, are an evil man,' she groaned as he added another finger, earning a whimper. She wriggled her hips in a desperate attempt for him to move his fingers; instead he placed a hand gently on her stomach to hold her in place. 'Castle, move,' she looked up at him hovering above her, still grinning.

'Nope,' he said enjoying the power he had. He moved his hand slightly but then stopped quickly again, giving Kate barely enough friction to satisfy her. She whined and tried to wriggle again, slowly realising that it was useless and he was in control.

'Castle, move,' she told him again, breathing heavily, trying to buck her hips to create some of the sensations she was trying desperately to create.

'What's the magic word Beckett?' he leaned in until her was millimetres away from her face. His fingers moved again, this time even less than before and she groaned in frustration.

'I'm not begging Castle,' she told him firmly, again trying to rock her hips against his hand which was still holding her firmly in place. He slowly started to withdraw his hand, now she could only feel the tips of his fingers inside her. She hummed in disapproval.

'All you have to do in say it,' he whispered to her, slowly placing a gentle kiss against her lips. She caught him off guard as she bucked her hips forward, making his fingers slide into her another inch. She groaned in pleasure. Kate couldn't take much more of this.

'Castle, if you don't do anything about it, then I'm going to have to do it myself,' she told him, furiously.

'Well detective,' he smiled at her against her neck, where he was placing kisses. 'As much as I'd like to see you do that another time, now it's my turn and all I want you to do is ask,' he rose back up again, removing his fingers almost completely and this time, brushing his thumb over her sensitive nub, earning another groan from her. She needed to come, now.

'Fine. Fuck you, Castle, move PLEASE,' she said desperately and with that he firmly thrust his two fingers inside, curling them up to reach her G-spot. She gasped as her eyes rolled back in pleasure. 'More,' she gasped out as his fingers pushed a little harder into her. He moved them backwards and forwards in a scissoring motion, thoroughly enjoying the grunts and moans leaving her mouth. 'Castle I need to come,' she said desperately, bucking her hips against him again. He finally lets her have her way as he thrusts his fingers twice more inside her before she's clenches around them and whimpers his name as she comes.

Kate turned her head to the side, breathing heavily as Rick removed his hand and pushed back her hair from her forehead. He could see a thin sheen of sweat covering her face, neck and chest and he leaned down and pressed a soft kiss to her scar. She hummed into him and nuzzled her head into his arm.

'Castle, you gotta stop making me want to take a nap,' she joked, her words slurring slightly from the pleasure he just inflicted on her. He let out a small laugh and pushed himself off the couch.

'Right, we've got to feed you now,' he grinned down at her.

'I'm not an animal Castle,' she replied through heavily lidded eyes.

'I think if you were an animal, you'd be a very sexy tiger,' he teased, kneeling down next to her. She let out a short laugh and feebly pushed him away.

'I'm going to order in. What do you want? Chinese, Italian?' he asked. She rolled over until she was on her side, her face millimetres from his. She sighed deeply.

'I don't mind, you choose,' she yawned at him, reaching a hand out to grasp his shirt and pull him in for a sloppy kiss. They broke apart slowly.

'I'll order a bit of everything then,' he smiled down at her, rising and walking over to the phone.

'Of course you will,' she smirked through closed eyes. Castle made a few calls before walking back over to her. She was still stretched out across the couch. As he grew nearer he could see that she was indeed asleep, with her mouth slightly open, breathing heavily. He looked down at the sight before him, entranced by her. She was so different when she was asleep. She looked so peaceful and content. Rick quickly snapped a picture on his phone for teasing purposes or blackmail when he next needed it.

Rick got out his laptop and sat on the armchair next to her and began writing. He was feeling particularly inspired by the beautiful woman sleeping next to him. He quickly got lost in his work and half an hour later there was a knock on the door. He swiftly paid the delivery boy and carried the food to the coffee table. He put it all down as quietly as possible but he saw Kate move out of the corner of his eye and stretch and yawn like a cat.

'Nice sleep?' he smirked at her, leaning down to brush hair out of her face. 'Food is here.'

'Yummy and I wasn't sleeping, I was just resting my eyes,' she told him.

'Sure Beckett, sure,' he replied, handing her some chopsticks and some spring rolls and sitting down opposite her. They ate in comfortable silence until they were stuffed. Kate put down the left-overs and leant back into the couch, resting her hand on her stomach.

'Ugh food baby,' she groaned, rubbing her hand across her stomach. Castle scoffed before moving to sit next to her. He sat with a small distance from her and a look of hurt and confusion crossed her face. He saw the confusion across her face and nudged her hand, resting next to his on the couch. He linked their pinkie fingers and gave her a hesitant smile. That was all it took for her to lean right into him and rest her head on his shoulder.

'Come on superman, you still owe me that movie night you promised,' she mumbled into his shoulder.

'I love it when you call me superman,' he replied, grinning proudly at her. She laughed and pushed him down onto the cushions and snuggled on top of him again. They started to watch and before long they were both fast asleep, sprawled along the couch. Kate was mostly on top of Castle with her leg swung over his hip and her head resting on his chest and he had a hand resting securely on her hip and another arm wrapped round her waist.

They were so deeply asleep that they were not aware of the door to the loft opening quietly and a figure padding softly across the room until it reached the couch. Martha looked down at the two sleeping forms before smiling at them and retreating upstairs to her bedroom to go to sleep.

This time it was Kate that woke first. They were still sprawled across his couch and Kate winced at sleeping in the same position all night. She slowly lifted her head off his chest and looked up at his sleeping face. His hair was ruffled and he had a sort of childish quality to him. She smiled sleepily at him and reached up to run her hand gently down the side of his face and through his hair. He stirred, wrinkled his nose and then stilled again. Kate chuckled and again reached to run her fingers, softly, along his lips and down his nose. He still didn't wake so she thought she'd go for a more direct approach and leant up and placed a soft kiss to his lips. She felt him grumble against her as she nipped gently at his lower lip and then continued to place soft kisses along his jaw and down his neck. She kissed the spot under his ear where she knew he had a weakness and felt him come to life.

'Katherine Beckett, are you giving me a hicky?' Rick asked her, his voice still laden with sleep. He reached both hands up to rub his eyes and stretched underneath her. She giggled and continued to suck on his neck. 'Not that I'm complaining or anything,' he said, moaning softly as her tongue slipped out to caress the small nips she was making on his neck.

She moved up to kiss his lips again, releasing them with a soft pop.

'Come on stud, I'm making you breakfast,' she grinned, slapping his chest and jumping to her feet. 'Pancakes ok?' she asked, already by the kitchen, banging around with the pots and pans. He watched her navigate her way around his kitchen. She knew where to find everything, probably due to the fact that she managed to cook a full cooked breakfast the time she stayed after her apartment got blown up. She started to mix the batter her brow furrowing with concentration. Suddenly she felt his arms wrap around her waist and leant back into him.

'You know you're kinda sexy when you go all domestic and start making breakfast for me,' he spoke into her neck nibbling down until he reached her collarbone. He found the hem of her sweatshirt and pulled it over her head as she turned in his arms and snaked her hands under his top to rub across his muscles. Soon enough his shirt was gone and she was lifted onto the counter. She linked her ankles around his waist and pulled him flush against her, groaning when their hips came into contact. He felt her hands wander down his lower abdomen and started to do the same.

A loud cough suddenly made then spring apart as Rick turned to steady himself against the fridge breathing heavily as Kate jumped down and grabbed her sweater before covering herself up. Martha was standing at the bottom of the stairs, smirking at them both.

Twin cries of 'Mother' and 'Martha' rang out in shock as they struggled to get their breath back and cover themselves back up.

'Mother, what are you doing here? I thought you were in the Hamptons?' Rick asked breathlessly as he put his top back on. Kate meanwhile was standing behind Rick, blushing furiously, enthralled by her feet or so it seemed.

'I was, until I received a call from Alexis saying that her father was acting strangely and she was worried. Now I can see why,' Martha replied, swirling around the island and reaching for a glass of orange juice. Castle grimaced and ran his hand over his jaw. 'Kate dear, you can come out. I can see you hiding behind Richard there,' she smiled warmly at her. Kate blushed even harder and took a step to the side putting her in full view.

'Hi Martha,' she said nervously. She was worried that Martha wouldn't be too friendly towards her after the past few months.

'Kate darling I heard about this last case? Are you alright?' she asked. Martha's concern overwhelmed Kate for a moment as she felt a lump in her throat. She blinked back her tears and croaked out her reply.

'I'm fine now, thank you,' she replied, smiling up to Rick as he leant down to place a kiss on her forehead.

'Good. Well then please, continue. Don't let me stop you from what you were doing. I'll be off now,' she replied, making both Kate and Rick blush profusely.

'Back to the Hamptons?'Asked Rick hopefully.

'No dear. While I'm here I might as well get some shopping in,' she smiled back at him, making Castle frown at her over-use of his credit card.

'See you later' she called over her shoulder. 'And Kate, it's nice to see you again, welcome to the family,' and with that she was gone. Kate let out a shaky breath and leant back against the counter with a bemused expression upon her face. Kate and Rick's eyes met as they burst into laughter.

'Well that was a surprise,' he stated, eyes wide.

'I can't believe your mum just caught us making out in your kitchen like horny teenagers,' she groaned, leaning forward to rest her head on his chest. She felt his chest vibrate as he laughed.

'Come on, we should probably finish breakfast and get ready. We don't want Alexis coming home early and finding us having sex in your kitchen, I somehow don't think she'd be as welcoming as your mother was,' she raised an eyebrow and poured out the batter.

They finished breakfast and Kate put on the clothes she'd brought with her the previous night. They were chatting away at the breakfast bar when they both heard a key turn in the lock. Kate's face immediately had an anxious look on it as she rotated on the stool to face the door.

'Hi dad, how was your-,' Alexis started, before stopping when she saw Kate. 'Detective Beckett, what are you doing here?' She asked, her voice cold and she had a frown plastered on her forehead.

'Please, it's Kate, Alexis,' Kate replied, nervously, shooting the young girl a small smile. Alexis nodded back at her. 'I'm...' she trailed off, not really sure where to start. Castle saw her hesitation so he moved round the island to stand next to Kate. Kate felt his warm fingers creep under her shirt and softly stroke her spin, attempting to soothe her.

'Actually pumpkin, we wanted to talk to you,' Castle replied, smiling brightly at her. Alexis looked confused and looked back and forth from her dad to Kate. She slowly walked towards them and crossed her arms, appearing defensive.

'Well sweetheart, Kate and I wanted to tell you that, well we've had a talk and discussed everything and we wanted to tell you that we're together now,' he told her, holding his breath, waiting for her reaction.

'This is sudden,' she replied frostily. Kate opened her mouth to speak but Alexis cut her off.

'What changed? No wait let me guess, my dad came crawling back to you as always and you, feeling sorry for him, decided to indulge him for a while,' she spouted out.

'Alexis!' Rick growled.

'No dad, I'm not done. Or how about this? Did he wine and dine you at the most expensive restaurant in New York and you decided that the best way to thank him was the screw him and then next week you'll decide that maybe you don't actually like him and it's time for him to leave the precinct,' Alexis, rattled on, fuming.

'Alexis!,' Rick hissed again. 'How dare you speak to me like that and Kate too,' he shouted at her, as Kate just sat gobsmacked.

'Sorry, Kate,' she seethed with extra sarcastic emphasis on her name. Alexis turned and fled up the stairs as they heard a door slam.

This chapter wasn't really heading exactly where I wanted it to go, I didn't expect Martha to pop up but you know what she's like and Castle and Beckett just kept jumping each other. Next up: A serious talk with Alexis. Hope you guys enjoyed it!
