Ambulance

The paramedic bandaged Castle's hand and stepped out of the ambulance he winces and unwraps some of the bandage as Beckett steps in to sit across from him.

"Hey there, Chuck Norris"

Castle couldn't help but let out a small chuckle

"How's the hand?" she reached out to slowly help him with his bandage.

"Uh, excruciating"

"Mm" she finished wrapping his hand before lightly feathering her fingertips over the bandage looking him in the eyes.

"How's Ryan and Esposito?"

"Mm, mild hypothermia, wounded pride, guess which one'll heal first…." She hesitated for a moment before continuing "thank you for having my back in there."

"Always"

She smiled at his response "hey can we go talk for a minute someone where…"

"Uh yeah sure, what about we talk on our way home I'm freezing out here"

She smiled and nodded, "I'll just let the team know, see you in the car?"

"Definitely"

Okay Kate you can do this you interrogate some of the filthiest murderers, you are not afraid to do this! She was trying to encourage herself to finally face her fears, to finally listen to her heart.

Inside the Car

They were pretty quiet at first both trying to process everything that happened earlier tonight that kiss, Castle couldn't wipe the smile of his face. It was better then he had ever imagined it to be he gently moved his fingers up to his lips still able to taste her sweet lips. Beckett saw from the corner of her eye what he was doing and she felt her cheeks warm up, from the way his fingers were touching his lips, all she could think about was how surprisingly soft his lips where. How just by kissing him, he managed to take her breath away and this scared her, because she can't think of any other time she has ever felt this way. Hell she was still with Josh and he has never managed to take her breath away, hell he was rarely around to even try.

She finally pulled up near Castles loft.

"Hey do you want to come up for a cup of coffee, you said you wanted to talk privately? I mean Alexis and mother are out of town on some beauty spa trip thing".

She hesitated at first and Castle cut in "I uh… I mean if you don't want to its okay we can talk another time if it's not important"

Beckett shook her head "no Castle its okay coffee actually sounds perfect" she gave him a small smile and nearly got lost in his eyes again. She made her way down to the garage parking next to his Ferrari. They soon made their way up to his loft he was telling the truth Martha and Alexis were nowhere to be seen which made her calm down a bit.

Castles Loft

Once inside, they both took their jackets of; Castle took both of their jackets placing them in the coat closet.

"Why don't you go sit down on the sofa and make yourself at home I'll get the coffee" Beckett just nodded and made her way over to the sofa.

The entire time Castle was preparing their coffees he just couldn't stop looking over at her oh god she is so beautiful, it's killing me knowing she is with that stupid Dr. Motor cycle boy, I just wish she would give us a shot we would be amazing together…. The beeping from the coffee machine brought him out of his thoughts and he quickly made their coffees making his way over to Beckett.

"Thanks Castle" She looked up at him grabbing the hot coffee from him, he sat down on the other side of the sofa turning to face Beckett who was now facing him as well, he noticed the concern look on her face.

"Everything okay Beckett?"

She breathed in biting on the bottom of her lip, before letting out a barely audible huff

"Uh yeah, look Castle about that kiss earlier"

He cut her off from finishing "hey, look it's okay I know you're with Josh, I promise you we can just forget it" he noticed the furrow in her brow and quickly added "uh… I mean if that's what you want…"

Oh god why does he have to be so sweet and understanding why can't he just tell her the cold hard truth? She breathed in again before answering trying to work out what to say.

"No Castle, I…. look I'm not good at this…"

He moved closer to her but only subtly trying not to scare her away he noticed her shift closer as well and he took this moment to place his hand on her knee he felt her leg tense up and went to move his hand assuming he went too far, she felt him about to move and suddenly without even realising she had placed her hand over his, and started moving her thumb softly over his knuckles. She looked back up trying to regain the strength to continue.

"I… that kiss Rick, I can't stop thi… I… it umm…." She stumbled a little bit before finally gaining enough courage to continue. "It meant more to me then it just being an undercover kiss, Rick I" she ducked her head trying to hide the tears that were starting to ease their way into her eyes. Castle moved the strand of hair that was covering her face, she looked back up at him she can't remember who moved first she's pretty sure it was her, but before she knew it her lips were attached to his. The kiss was slow and tender unlike their first kiss she was the one to deepen the kiss leaning more into him and he slowly moved down to lay on the sofa, slowly pulling her along so she was now laying on top of him, she ran her fingers through his soft, hair he moved his hands down to her hips slowly rubbing circles into the side of her hips. When air became a necessity, Beckett slowly pulled away pulling on his bottom lip causing him to let out a small moan she rested her forehead against his head. Both trying to catch their breaths

"Kate?"

"I'm… I'm sorry Rick I uh… I shouldn't have" she started to get off of him but was pulled back down by the force of his arm she fell between the edge of the sofa and his body still slightly raised by his torso. "Kate… is this… us what you really want?"He was still holding her slightly in his arms god he wants this so much he just wants to be able to stay like this for ever. Never needing to move from this spot right here ever again. "Because you, I've wanted you for…. Oh God… so long Kate".

Beckett could feel the air escaping her lungs her heart racing she leaned in and softly ran her hand through his hair trailing down to the side of his face, cupping the side of his face. "Honestly, Rick… Yes… but god Rick I am so scared…"

"Scared of what? Kate"

"Scared… I'm scared that if I give you… If I give my heart to you…" she tilted her head down a little. And he placed his index finger underneath her chin tilting her face to look back at him.

"Hey, you can tell me anything okay Kate"

She breathed in and looked him in the eyes, "I'm scared if I do this, what happens if something happens and I lose you or… what if for some reason we don't work I can't Rick… I… uh don't think I could survive that Rick I just know I couldn't… my heart… I just…"

He pulled her back in for a soft kiss when he pulled back he smiled up at her.

"Kate, look I can't promise that nothing will ever happen to me but I can promise that I will never stop lo... Never stop thinking about you; you have stolen my heart Katherine Beckett always. I know you're scared and I understand after what you have been through but you need to know that I'm not going anywhere. I've been here three years and I can tell you right now it is no longer about the books it's about being able to be around you every day Kate." He knew not to tell her that he loves her yet because this is all so new for them.

She couldn't believe the words that formed in his mouth the way he spoke to her with such love hang on was he about to say that he loved me? No I mean I think I lo… no, no it's too soon to say that not yet.Kate noticed he was looking up at her with a slight panicked look, and she leaned down to give him a slow tender kiss which for now was her way of saying she loved him.

As he scooted down and turned to his side so Beckett was laying back down in between the chair and his body they were both laying, on the sofa in a hugging position looking in each other's eyes, he held onto her by the waist whilst her hands were trapped between their bodies. Then it dawned on him crap, how could he forget.

"Kate, as much as I hate to ruin this moment… what about Josh?"

She breathed in heavily god how had she forgotten about him, and as much as she loved did she just say love?.She wasn't a cheater and she knew what she had to do. "Rick, we can't do this" she insinuated between the two of them and his face looked like it had just been hit with the worse new possible, she noticed the change in his face "before you freak out let me finish" she gave him a smile. "I need to end things with Josh if we're going to do this right; I need to break up with him before we go any further because I'm not that kind of girl Rick and I know you're not that kind of man either". She leaned back into his chest taking in his scent.

"That is understandable and when you break up with him remember that I am here always" he started drawing lazy patterns on her back, just taking in exactly how far they had made it since this morning.

"Thank you Rick, just know you are in no way a 'rebound' no matter what Josh says, because it's always been you Rick always I was just too scared to follow my heart"

He looked down to see her now looking up at him "what do you mean no matter what Josh says?" he was confused normally he was good at reading whatever Kate said through the lines but he couldn't understand this time.

"Let's just say he isn't the biggest fan of us, working together…" she looked up at him then noticed the time it was only 10:00pm but she knew if she didn't leave now, she would probably end up staying the night and she wasn't ready for that just yet. She didn't want to ruin what they were just starting between them, although she definitely knew that when she and him would soon make love there would be nothing to ever compare it to because he was by far her one and done.

"No offense Kate, but if I was him I would be a bit anxious to I mean I am irresistible" he gave her his signature Castle smirk and she lightly slapped him on the cheek shaking her head "your ego boy tsk, tsk" she smiled back her eyes lighting up the entire room well at least to Castle they were.

"Rick I should go before I fall asleep and I want this to be right between us no sneaking around which includes me cheating on Josh, I promise as soon as I see him I will do it, he is on night shift tonight and as much as I hate to say it he will be at mine tomorrow morning we're suppose to have breakfast together" Castle cringed at her answer but squeezed her tighter.

They made their way to his door and before Beckett left Castle pulled her in for a hug as she let go he simply whispered:

"Thank you".

"For what?"

"For giving us a shot"

She just gave him a smile "See you tomorrow Rick"

"Until tomorrow Kate"
