A/N: So it seems I did find it! This is another seaon 4 one that I had saved on my computer from AGES ago. This first chapter is quite short, but I think the rest of them are slightly longer. There will be a few fights and misunderstandinds because, let's face it, the're both hot heads on occassion.

Hopefully you like it.

Let me know what you think.

A banging at her door woke her out of her novel. After a tough case, all she wanted to do was wrap a blanket around her and snuggle on her couch while she read Nikki Heat. Castle had been hanging around all day, sticking closer than normal and it was doing nothing for her self-control. Lately, all she wanted to do was throw him into the nearest interrogation room and have her way with him and Castle sticking her like glue was not making it any better. Kate was getting to page 105 again; just getting to the good part, letting her mind run away with her where her body could not. She wanted to flay whoever was on the other side of that door for interrupting her fantasies.

Kate sighed closing her book with one of his notes he wrote for her once. It wasn't anything of importance, just a note asking her to dinner at his loft with Alexis and Martha, but it was to her from him, and that's what made it special. She put the book on the coffee table and got up.

There was knocking again. Impatient. Ok, whoever it was, they were getting on her nerves.

'Alright, alright.' She mumbled angrily. She looked through the peephole and she gasped loudly. She pinched herself; now way he would be on her doorstep, right when she's feeling as ... well... randy as she is now.

'Kate?' he said through the door, looking into his side of the peephole. Kate ducked, though she had no idea why. 'Really?' he said. Crap! He saw me! Kate said to herself.

'C'mon, don't play dumb. I know you're in there, Beckett, I can see your shadow.'

She unlocked the door and let him in. 'There's a mirror on my door?' she asked smiling slightly, hoping he wouldn't see her blush. Something was wrong. He didn't crack a smile; yeah, ok, it wasn't a great joke, but even he laughs at lame jokes: most of them come out of his mouth. He just walked straight past her into her lounge room. She closed the door behind him a little shocked. He had barged into her home before, but his demeanour was different: off somehow. She was worried about him, but more importantly, why did he have to be here, right now? Him being here, in her apartment, by themselves; where there was endless possibilities, where it was hard for her to think when he was in her presence.

He took off his jacket and hung it over the back of the couch. He hadn't looked at her yet.

Kate looked down, remembering she was in her sweats and tank top; ready for bed. She watched him for a moment, he still hadn't turned around to her. Her thoughts went back to page 105 again, heat spread through her once again and she shivered in arousal, and she was glad he hadn't turned yet.

'What's up, Castle?' she said pushing off the door and covered herself with her arms.

He didn't answer her, just stood with his back to her. Kate didn't realise he was looking at the book on her table and knew exactly where it was being marked, and if he wasn't mistaken, what it was marked with. It made his heart ache and his resolve harden. He was going to do this. He was going to push her that little bit further because they both know that she's ready now, he sees it in her eyes at work and when she comes over to the loft or they hang out after work with the guys at the Old Haunt. Kate's the one that has innuendo oozing out of her mouth, touching him whenever she can and, he's not sure if she realises it, but she gravitates towards him, leaning slightly into his personal space whenever she can.

He's doing this, he is. C'mon, Ricky, stop being a coward.

'Castle?' she said a little more anxiously. He didn't answer her again.

'Rick?' Kate reached out to shake him from his stupor. He was really starting to scare her. She wasn't expecting what he did next.

He spun around and took her waist and neck in his hands. Kate's breath hitched. Please, she begged silently. She didn't know whether it was to kiss her or let her go. She didn't have a lot of time to process anything when his lips made the decision for her.
