AU: This particular fanfic is based off of the most recent episode of Castle, "The fifth bullet". There are a lot of hints in the episode towards a possible relationship forming b/w Becks and Castle, and this scene just seemed to spark something within me. This fic is rated "T", because I didn't feel the need to put in any smut and such. It is meant to be short and sweet, a savoury moment between the two. Anyway hope you like it, and as always plz review!

Disclaimer: I never remember to do this but, since i actually did, I don't own Castle or any of it's amazing characters!

Coffee Induced High

Detective Kate Beckett was deep in conversation with her fellow investigators Esposito and Ryan. They had just discovered that they had a key witness to their case; unfortunately he had no clue who he was. The witness had been supposedly suffered some sort of trauma during the event and was suffering from amnesia. It seemed that any tiny stride they made towards solving this case, ending up putting them three steps behind. After telling Esposito and Ryan to check the coat for GSR, blood and other useful evidence she got up from her desk rounding the corner quickly. Not looking where she was going, she collided head first into her quirky partner, novelist Rick Castle.

Hot coffee splashed painfully down the front of Beckett's white blouse, thoroughly soaking her, as she yelped in surprise. Castle stared in astonishment as he continued to hold two coffee mugs in his hand. "I brought you coffee" he said, doing his best to keep his gaze upon her face and not the rapidly becoming transparent shirt front.

"Thank you Castle" she replied, sighing at her ruined shirt. She gently plucked it away from her skin as she grabbed her coat and raced off to the nearest washroom she could find. Seeing the sign for the co-ed single washroom up ahead she quickly retreated into its windowless safe haven to attempt to clean up the mess.

Closing the door behind her, she made her way over to sink, where she grabbed a few paper towels from the dispenser and began to use them to soak up some of the coffee. After getting rid of the excess liquid, she wetted a few and began wiping the large brown spot on her blouse. Though she did the best that she could, the stain was not lessening and she was only proceeding to make her shirt even wetter. Unbuttoning her shirt to her belly button, she attempted to get at it from underneath, when she felt of whoosh of air as the bathroom door opened.

Castle burst through the door, head down as he rambled, "Beckett, I'm so sorry, I was just trying to help…" The door swung shut behind Castle as Beckett stopped her work.

"Castle!" she screamed, "what are you doing in here!" It wasn't until then that Castle chose to look up at Beckett. Her face was red with embarrassment, or possibly anger, he couldn't tell, and her once white blouse was covered in a large brown stain. The blouse was open down to her bellybutton, revealing her white lace bra, the wet fabric clinging to her suggestively. Castle could only stutter in response as he took in their current situation.

"I… uh, came to apologize…" Beckett sighed, glancing down at the paper towel in her hand. Knowing her attempts at salvaging the shirt were hopeless she threw the towel on the countertop and looked up at Castle. As she looked up into his face, she couldn't help but giggle at him. He was desperately trying to not look at her exposed torso, but every time to tried to look away his desire to look at her would win and he would continue to follow her curves. Receiving no discouragement from Beckett, he finally allowed himself a good look, eyes raking over every curve of her body. Beckett shivered, seeing his eyes grow dark with lust.

Her shiver caused Castle to glance up at her with a questioning look. "Are you cold Beckett?" He immediately moved towards her, shucking off his suit jacket and draping it over her shoulders.

Kate smiled gratefully. "Thanks Castle. These washrooms are kinda drafty, which doesn't help a girl with a wet shirt out." She smiled once more at her attempt to joke. Castle smiled back and came to stand beside her, using his hands to create friction on her arms, as he rubbed them up and down over the coat. Beckett leaned into him, gathering herself in his warmth. Castle continued to rub her arm, but his hand slowed, rubbing more for comfort than for heat.

As Kate inhaled the unique scent that was Richard Castle, she couldn't help but sigh in contentment. "Enjoying our hug Beckett?" Castle asked with a slightly teasing tone in his voice.

Beckett nuzzled his neck ever so slightly. "Actually, yes. I never knew you were so comfortable Castle." The couple chuckled, Castle bringing her closer in his embrace.

"I really am sorry about the shirt Kate. I can buy you a new one if you'd like."

Kate pushed herself slightly away so she could look into his eyes. "It's okay Castle, I know it was an accident. The shirt's really not important."

Castle flicked his eyes over hers, before finally nodding his head. "Kate there's something I've been meaning to tell you" he said, still holding eye contact.

She could feel her breath catch at his words. Though she tried not to show it too much around her colleagues, her feelings for Castle had greatly developed, and there were days in which she yearned for moments like this. "Yes, Castle? What did you want to say?"

Rick took a deep breath before speaking. "As you might have guessed, I've been attracted to you for quite some time now." Kate's eyebrow shot up incredulously. That was a bit of an understatement.

"Go on…"

"Though I automatically felt that physical connection with you, I've feel like I've really gotten to know you as a person over the past several months. You've been kind enough to let me in, and show me some sides of you I would never have known. So, anyway, what I'm trying to say is thank you. Thank you for putting up with all my childish comments, and my constants prying. You've been very patient, and I love you for it."

Kate smiled, her eyes shining with tears as she listened to what Rick had to say. Seeing her tears, Rick used his thumb to brush it gently away from her eye. Kate tenderly placed her hand on his cheek as she leaned in to place her lips upon his. The kiss was slow and loving, full of emotion and meaning. As she pulled away she gazed into Rick's eyes, as a single tear flowed from her eye. "I love you too Castle."
