This just sort of happened accidentally.

Disclaimer: I don't own Castle or the characters.

Castle woke with a start to the sound of his phone ringing.

"Beckett?" he answered, after seeing her name on the caller ID and had answered the phone. He really hoped they didn't have a case, it was 3am and he'd really like a bit more sleep.

"Sorry, did I wake you?" replied Beckett, but she knew she'd woken him, it was 3am after all, she just really needed to talk to him and this couldn't wait.

"It's fine, do we have a case?" asked Castle, already trying the find the motivation to get out of bed.

Beckett paused before replying, "No."

"Is everything okay?" Now he was confused, why would she be calling him so late (or so early) if they didn't have a case?

"Everything is fine, sort of. Can we talk?" She couldn't chicken out now, she was ready to do this.

"We are talking," replied Castle, laughing slightly, still only half conscious.

"Castle," answered Beckett in a disapproving tone, but she couldn't help but think about how cute he sounded so sleepy like this.

"Fine, sorry, what do you want to talk about?" asked Castle, finally finding the energy to sit up in bed.

"I mean can we talk in person?"

"Okay then," Castle answered, wondering what was so important that she wanted him to go meet her and that it couldn't wait until the morning, "Do you want me to come over?"

"No, I want you to open your door and let me in."

"You're here?" asked Castle, his brain still wasn't fully functioning yet.

"Yeah," a pause, "Is that okay?"

"Of course, just give me a minute," answered Castle and then he hung up the phone, got out of bed and made his way to the door.


Beckett couldn't believe that she was actually doing this but she'd decided she'd wanted to tell him how she felt and as soon as she'd decided that, she realised she couldn't wait. So she'd gotten out of bed and went straight to his loft to tell him the truth.

She'd been prepared to see a sleepy Castle standing on the other side of the door when he opened it but what she hadn't planned on was a sleepy, shirtless Castle standing on the other side of the door. But there he stood, only in his pajama pants, his bare, broad chest right in front of her.

"Hey," said Castle, seeming not to notice Beckett staring at his chest.

"Hey," she replied, finally dragging her eyes up to meet his but she couldn't stop her eyes from glancing back down at his chest and his muscular arms.

"Beckett?" asked Castle, forcing Beckett to look up to his face again but this time he'd caught her looking and had a teasing look in his eyes, "Like what you see?"

"I…shut up and go put a shirt on," Beckett replied, wishing away the red colour that was now staining her cheeks.

Castle gestured for her to come inside and then shut the door behind her.

"I'll just go put a shirt on then, if you're sure that's what you really want?" Castle teased again, laughing when Beckett blushed even more.

He left to quickly grab a shirt and came back into the room a minute later, now wearing a black shirt which she knew he'd chosen on purpose, it was tight fitting and didn't leave much to the imagination.

"Coffee?" asked Castle.

"Sure," Beckett answered with a smile, giving her a minute to breathe and try to focus on what she had come here to say.

Beckett made her way over to the couch and was sitting when Castle returned with two cups of coffee. He gave her one and then took a seat next to her on the couch, ready for whatever conversation Beckett wanted to have.

"So, you wanted to talk?" asked Castle when the silence got too much for him. She'd just been sitting there slowly sipping her coffee and he really wanted to know why she was here at this time in the morning.

"I was just doing some thinking earlier and I…" she trailed off, now she was here, she didn't know exactly what to say.

"And you…" Castle prompted, wondering what could be so important that she'd come all the way over here to talk to him and why she suddenly seemed so nervous.

When she continued to sit there quietly, Castle tried to think what this could be about, running his mind through previous events that may warrant a talk like this. His mind paused when he realised why she may be acting the way she is, all nervous and not particularly willing to talk now, he'd made her uncomfortable before. While that obviously wasn't the reason she'd come over in the first place since it just occurred, it does explain why she's acting nervous now.

"Look, about before, that comment about you liking my chest, I didn't mean to make you uncomfortable, I'm sorry," said Castle, rather embarrassed about his actions before and the need to apologise now. They'd been walking a thin line recently, one where she seemed to be increasingly flirting with him. But when it was the other way around, he felt guilty for pushing her, knowing she wasn't ready for a relationship with him or anyone else.

"No, Castle, no, there's no need apologise, not for that," replied Beckett, feeling guilty that he felt the need to apologise for flirting in the first place.

"I don't understand then," Castle said, not following what Beckett was saying now.

"Understand what?"

"You seem nervous, uncomfortable, and I thought maybe my actions earlier were to blame for that," replied Castle, looking down as he spoke, not wanting to look her in the eye.

"You mean when you caught me staring at your chest?" Castle's eyes flew to Beckett's at her words, noticing the blush had returned to her cheeks.

"Well, I…" Had she really just admitted that she was checking him out? Because that's sure what it sounded like. And he did catch her looking, called her out on it, but he didn't think she'd admit it so willing now.

"Because that's what I was doing, and I'm not uncomfortable, just nervous, trying to figure out how to say what I came here too," Beckett replied, building courage with every word she said.

Castle had to stop himself from pumping his fist into the air because she'd just admitted that she was, in fact, checking him out and that was worth getting up at 3am for.

"And what did you come here to say?" Castle asked when the rest of her sentence registered in his mind, hoping this was going where he'd desperately wanted this to go for months now.

"That's the hard part, isn't it?" Beckett replied, smiling at Castle and the confused look on his face. "I realised something earlier and then as soon as I had, I had to tell you."

"What did you realise, Kate?" Castle asked, his hand reaching out to take hers that was resting on her knee, the coffee long forgotten and now sitting on the table in front of them.

"That I should have done this a long time ago," she answered before she leaned forward and pressed her lips against his.

She pulled away far too soon for his liking.

"Not that I'm complaining, but what was that for?" asked Castle once he'd gotten his breathing under control, not being able to keep the smile off his face.

"Because I've run out of reasons why we shouldn't. Because I'm tired of fighting my feelings for you. Because when you look at me with that smile, it's all I can do to stop myself from leaning over and kissing you." She smiled, the smile she was referring to was the one she saw increasingly around the precinct and the one he's wearing now, the one that says he loves her with all his heart.

"You mean this smile?" he asked, his smile growing wider as he leant forward to kiss her again.

"That one," she answered, kissing him a third time because now that she had, she really couldn't stop herself.

He pulled away from the kiss and rested his forehead against hers, just enjoying the feeling of her being so close.

"So, you came here to kiss me?" asked Castle a little while later. They'd shifted positions, her head now resting on his shoulder with his arm around her, his hand running up and down her arm.

She lifted her head off his shoulder so she could look at him while she spoke, "Well that, and I wanted to asked you something."

"Ask me what?"

"If you'd have dinner, or drinks, or go to a movie or anything really, with me."

She'd come here at 3 o'clock in the morning to ask him on a date and if Castle thought he was dreaming before then he really must be now because he'd never be lucky enough to have Kate Beckett come all the way over to see him just to kiss him and ask him out, this can't be real life.

He must've been quiet for too long because she spoke again, sounding nervous again, "Castle?"

"Dinner, movie, I don't care, as long as it's with you," he replied, pulling her back against him for another kiss.

"Okay," she grinned when he'd released her mouth, a matching grin on his face.

"I guess I should probably go home," said Beckett a while later after they'd just been sitting, enjoying soft kisses and being close.

"Don't go," Castle pouted, gripping her arm tighter, not wanting her to leave just yet. Ever.

"I have to, we have work tomorrow, we need to get some sleep." She saw Castle about to interrupt and she knew what he was going to say so she continued, "you know there won't be much sleeping if I stay."

He groaned at the image she'd just put in his head, ducking his head and kissing her neck, trying to show her some of what she'd be missing out on if she left.

"Castle," she said, trying to sound admonishing but it came out breathy.

"Castle," she tried again, this time sounding firmer but not like she wanted him to stop.

He must've understood what she was trying to do because he pulled away anyway, "sorry."

"There's no need to ever apologise for that either," Beckett said, placing one last firm kiss on his lips before pulling away completely and standing up, feeling the loss of his warmth instantly.

Before she could change her mind and crawl back into his arms, she made her way over to the door, Castle following her.

He opened the door for her but she could tell he didn't want her to leave, and that just wasn't because they wouldn't be able to make out any more.

"Hey," she said, stepping into his arms once more, "this, you and me, I'm in this, I'm not going to wake up tomorrow morning and decide I don't want this, okay?"

"Okay," he replied and she kissed him again.

"I want you and I won't regret this, I just think we should take things slow," she said before kissing him yet again.

"Okay," he answered again before grinning big and placing a goodbye kiss on her lips.

He closed the door behind her after she left, and leant against it, the grin from before still present on his face which he figured would be there for a while because he was so happy right now.

He couldn't believe it, Kate Beckett, the love of his life, had just admitted that she wanted to be with him too. She had come over in the middle of the night just to tell him that and he couldn't be happier.

His last thought as he drifted off to sleep that beautiful early morning was how good his life was at the moment and how he couldn't wait to see what the future had in store for them now that they were finally together.

Let me know what you thought.
