I'm not completely sure about this chapter but hey this is how my brain wanted it and I'm not going to argue with it. Also, at sections it might seem like light M but I don't think the rating needs to go up although if you disagree with me I will quite happily up the rating. Thank you for your reviews on past chapters and I promise there will be more to Caskett than just sex!

Slipping into her apartment later that evening, she groaned as she kicked her shoes off, her feet aching from the evening of dancing and walking around the charity event on Rick's arms, laughing while his mother auctioned him off to the begging women (and men) who were immediately bidding on him the moment they found out he was free, single and available for a whole evening of their choice. Sighing, she felt someone's eyes on her, amusement covering her face as she turned to see him standing there, staring at her, his smile growing. Half running, half walking, she approached him, their arms wrapping around each other as they began to kiss, their kisses getting more passionate with every movement. Undoing his bow tie, she threw it onto the phone before unbuttoning his shirt, her lips moving down to kiss the newly exposed skin in front of his as his hands ran down her back to her ass and then back up again, enjoying the touch of her under his hands and the warm comfort of her lips on his skin.

"Tonight has been the hardest night of my life" he commented as she kissed one particular spot on her legs. "Standing in a room with the most beautiful woman and not being able to touch her" he whispered, a smile covering her face as she moved away slowly and took hold of his hand. "I don't know I'm letting you do this, you didn't bid for me tonight and now I have to spend a whole evening with a woman I'm not interested in" he declared, a smirk appearing on her face as they entered her bedroom, his hand going for the light. Grabbing his hand, she shook her head at him. "I can't see you".

"Maybe I don't want you to see me Rick, maybe I want to experience different senses tonight, enhance our sense of touch and hearing and even taste" she whispered seductively into his ear, smiling as he groaned to himself. Leading him towards the bed, she smiled as she led his hands to the back of her dress, smiling to herself as he began to undo it while kissing her neck, feeling the material slowly drop to the floor as another groan left his lips as he realised that Kate Beckett was standing in front of him dressed in hardly anything and the only light in the room was the dim moonlight that entered through the gaps in the curtains. "Richard Castle, I feel very underdressed right now and I think you should lose the clothes" she ordered the smile growing on her face as he grabbed her hand and led it to the final buttons on his shirt. Pulling the material from him, she flung it somewhere within reach of her side of the bed, knowing she'd want to dress herself in it later when they began to fall asleep. She felt a strange sense of comfort when she dressed herself in his shirt, the strong odour of his aftershave and the general largeness of it in comparison to her own clothes gave her the protection she wanted but of course she'd never admit that to him, knowing the sort of man he was. Lying herself on the bed, she smiled as he moved closer to her, her hand immediately reaching for his pants, wanting to free him of the restraints that were separating them from each other. Bringing his lips to hers, he groaned, pulling away the final pieces of clothing she was wearing as she did the same to him, their bodies desperate and that's when the familiar loud ring of her phone filled the room. "No, not now, please not now" she begged, rolling over underneath him to grab it off the table and press the button. "Beckett" she snapped quickly. Putting the phone down quickly, she climbed off the bed, flicking the light on quickly to find herself something to wear.

"They've got a new lead haven't they and you being the marvellous Kate Beckett have to go and check it out" he moaned as she nodded, watching him collapse onto the bed and cover his face with his hands. "Do you want me to come in with you?" he asked her head shaking quickly as she found a pair of pants and pulled them on. "I could keep you company in case you get bored".

"Rick we were one second away from having sex tonight, I am aroused and very close to just jumping you this very second. I really don't think it's a good idea you coming into the precinct tonight when I'm this desperate" she explained, a small laugh leaving his lips as she rolled her eyes at him. "Honestly, at least at the precinct I'll have some control because I'm not attracted to Esposito or Ryan or Montgomery" she explained, quickly finding herself a shirt and pulling it on over the bra she'd just put on as Rick continued to watch. "God I thought tonight we could have some time, it's been three weeks" she moaned as he climbed off the bed and wrapped his arms around her waist, pressing a kiss against her cheek gently. "Don't do that, I won't leave".

"I'll stay and wait for you if you like?" he whispered, her head shaking once more. "I don't want to go back to an apartment where everyone's asleep Kate, all I'll think about is you and how breath taking you looked in that dress" he admitted, her eyes rolling once more at him. "At least if I stay here I know there's a small chance we might get that moment alone, I never thought I would be addicted to anything but right now your my own personal drug and I'm suffering right now".

"Fine, you can stay here but not going through my things Castle" she ordered, pulling her shoes on quickly before turning and kissing him. "Just don't go through my things" she begged as he nodded, watching her quickly run out of the room, the sound of her grabbing her stuff echoing around the soon empty apartment.

XOXOXOXOX

"Kate, Esposito tells me you snapped at him on the phone" Lanie laughed as Kate joined her in the morgue later that evening, stress covering the brunettes face as Lanie watched her in complete amusement. "Must have been something really important if you snapped at him for calling you into work" she added as Kate groaned, her eyes shutting as she slouched back in the seat.

"I was with someone and we were just about to, you know it, we were actually on the bed practically there and he calls me telling me they've got a lead, I have never wanted to kill them so much in my life" Kate moaned, a smile appearing on Lanie's face as her friend groaned from the memory. "I haven't seen him in three weeks and it's hard to see him outside of this job and I could have just blown my last opportunity for god knows how long" she continued to rant, Lanie quickly sitting herself beside her.

"You must be desperate" Lanie smiled. "I've never seen you get this stressed about a man before, it's quite amusing" she laughed, Kate hitting her arm gently as Lanie continued to laugh. "Look what are you doing right now?" she asked, Kate shrugging as she realised she wasn't doing anything important and that Ryan and Esposito were the ones busy chasing suspects. "No one would miss you if you snuck out for about an hour and came back saying you had to do something personal, you might actually work better once you've got this pressure off yourself".

"You're telling me that I should sneak off work to go and have sex with my mysterious lover" Kate checked, Lanie nodded in agreement as Kate stood up and laughed before walking towards the door, the smile not disappearing from her face. "Remind me to thank you later Lanie" she called from the lift, Lanie nodding to herself as she slowly began to get to work again.

XOXOXOXOX

Opening the door to her apartment, she smiled as she saw Rick sat on her couch, the phone pressed against his ear as he continued to nod his head while listening to the person on the other end of the line. Silently closing the door behind her, she sighed as she listened in to his conversation, desperately wishing they'd hang up so she could do the one thing she'd came for.

"Yes Alexis, I will be home later I promise, I just have some work to finish here" he declared, turning his head to see Kate standing there, unbuttoning her shirt, his eyebrows rising as she threw the material onto the floor. "Look pumpkin, I've got to go but later on I promise we'll have a movie night, me and you" he announced, going silent for a moment as he listened to his daughter. "When I see her next I'll ask Beckett if she wants to come too and you know I'll persuade her into coming if she can't be persuaded already by the idea of an evening with me and my brilliant daughter" he laughed, Kate rolling her eyes at him as she removed her shoes. "Okay, I'll see you later goodbye" he announced, hanging up quickly. Putting the phone down, he smiled as she walked over and kissed him, straddling him on the sofa quickly, glad that he was only dressed in his boxers.

"I only have an hour before I have to be back, so no stupid things now" she ordered, his head nodding as he noticed how beautiful she was even when she was desperate and stressed, her lips moving against his neck, wanting to mark him as hers so any woman was warned off.
