AU: Since you were all begging me to bump this story up to an M rated fic and let Beckett and Castle get down and dirty, I decided I should listen to the "fans" and give them what they wish. I did have a little trouble getting explicit when the time came, so go easy on me okay? Though I enjoy reading lemons once in a while, I' m still kinda embaressed to write the descriptively.

Anyway, this one shot is based upon Season 1, epsiode 9 "Little Girl Lost", when Beckett's ex comes back and she finds herself questioning her relationship with both Will and Castle. I'm having some trouble finding really good Caskett scenes to work off of, but I'll do my best to update soon. Hope you all enjoy, and don't forget to review!


As Kate watched Will leave she couldn't help but wonder about his request. If she really wanted to get back together with Will, she could. There was nothing really stopping her from trying again, accept…Castle. Though she hated to admit it, she was beginning to feel some serious feelings for the writer. When he had said that she could call him, even just to talk, she was astonished at his perceptiveness. He could tell that she was fighting mixed emotions over her feelings for Will and so he offered the thing she needed the most, a friend. Though he annoyed the crap out of her sometimes, he was constantly proving just how good a guy he really was.

Castle sat down across from Beckett in his usual chair, commenting on the departing FBI agent. "Nice guy. I can see how it wouldn't work though"

With a bemused smirk on her face, Kate replied, "Really?"

"Sure. Handsome, square jawed, by the book" he said giving Beckett a look.

"And that's a bad thing?"

"Yah he's like the male you." Kate shook her head, biting her lip to keep from smiling. "Ying needs Yang, not another Ying. Ying Yang is harmony" he said forming his hands in a circular motion to further describe his point. "Ying Ying is a name for a Panda." he cheekily replied.

Giving Castle an exasperated look Kate asked, "And who do you think would be better for me if not Will?"

Having had worked up to his goal, Castle grinned. "Me"

Kate looked over at Castle's face carefully. Was he asking her out? After Will just offered to start their relationship back up? After he had caught them kissing in the kitchen? She sighed and bit her lip nervously. Leave it to Castle to make things complicated.

"Are you implying we should go out?" she asked.

"Actually, yes. Why not?" he held his hands up in a questioning gesture.

"How bout the fact that we just worked a case with my ex boyfriend, who you saw me kissing in the kitchen, and the fact that I'm sure you know I'm totally confused on the matter."

Castle gave her one of his trademark grins. "Those are all the reasons why we should go out. You need a distraction from you past, time to think about your future." Castle's eyebrows rose playfully as he spoke the last part.

He does have a point thought Kate. She needed a good distraction, and what was better then the annoying, yet extremely flirtatious and playful Castle? "Okay Castle, you win."

"Great!" he beamed. "I'll pick you up at eight. I want to take you somewhere nice, so dress up, but nothing too black tie okay?"

Smiling Kate agreed. "See you tonight Castle."


Castle was due in about an hour, and Kate was stuck trying to determine what to wear. Having already donned her best date underwear, a lacy black push-up bra and panty set, she was left to flick through her small collection of dresses. After narrowing it down to a few choices, she finally picked a beautiful red silk number. The dress had a fitted bodice that showed just the right amount of cleavage, and a fuller skirt that flowed beautifully off her hips. Picking out matching black peep-toe pumps she zipped up the dress and made her way into the bathroom to apply her makeup.

Just as she was spritzing on her favourite perfume a knock came at the door. Kate made her way over to the door, glancing at herself in the mirror on her way. Taking a deep breath she opened the door to a strikingly handsome Castle. Rick was wearing a well tailored black suit with a midnight blue shirt and matching striped tie. His black dress shoes were shined to perfection, and his best Castle smile was set on his face.

Once Kate had opened the door fully to let Rick in, Rick's expression changed from happy to lustful within seconds. His eyes slowly roamed her body as he took her in, lingering on her revealing cleavage and toned calves. Kate rather enjoyed the admiration at first, but the longer Castle looked the more uncomfortable she was becoming. She cleared her throat nervously, bringing Rick back to attention.

Training his gaze on her eyes he whispered, "Wow Kate" Beckett blushed. "You look absolutely breathtaking."

"You're not so bad yourself Castle" she flirtatiously replied.

"Yes, well I was dressing to impress, which isn't always an easy thing to do with a woman such as yourself." Beckett glared at Castle as she closed the door behind her.

"And what is that supposed to mean?" Rick could feel her tensing up, preparing to chastise him before the night even started.

"I just meant that you not one of those woman who are easily impressed by my money, fame or charm. You're a strong and independent woman, and you don't throw yourself at me like most women." said Castle, flashing Beckett a warm smile to further his point.

Beckett instantly calmed down and allowed herself to coyly smile back at Rick. "Would you like it if I threw myself at you Castle? Is that what you want out of this date?" She stepped closer to Castle to increase the tension she was creating.

Rick's mind instantly flooded with images of Kate writhing naked on his bed as he had his way with her. Slowly swallowing to regain his control he respectively answered, "This date can be whatever you want it to be Kate. There's no pressure here, you can just be yourself and relax" Kate seemed to breath a slight sigh of relief. "Although if you want this date to end up in bed I'm more than willing" he added. Kate rolled her eyes as Castle's sensitive side made way for his playfully flirtatious side.

Grabbing his hand they descended down the stairs and to his car, where he politely held the door open for her. The ride over was fairly quiet as they just enjoyed the comfortable warmth of each other's presence. Castle eventually pulled up to a beautiful Italian restaurant, on the East side of New York. Leaving the car with the parking attendant they made their way into the restaurant to be seated at the table Castle had specially reserved. As the waiter filled their water glasses and arranged a bountiful basket of breadsticks on their table, the couple settled into their seats and picked up their menus. The waiter took Castle's order for a bottle of red wine before leaving the two to decide what they wanted for dinner.

"This place is beautiful Castle, where'd you find it?" asked Kate.

"I've met my publisher here a few times. She has a very rich Italian background and absolutely loves this place."

Kate took a look over the menu, mouth beginning to water as she read the descriptions of each particular dish. "This all sounds so good. What are you getting?"

Rick took a second to scan the menu before deciding, "I think I'll try the veal parmesan with fettuccine alfredo. Their pasta alone is to die for, no doubt pasta and veal will literally send me to heaven." Beckett chuckled.

"I was debating between a few things, but I think I'll go with the angel hair pasta with grilled shrimp." Having decided on their meals, they placed the menus in a neat pile at the corner for the table and took a sip of their wine.

Kate desperately searched for what to say next, coming up with a feeble attempt to start the conversation. "So, that was quite a case we had today, very back and forth. I don't think we would have solved it, had you not made that connection with the bunny."

Castle grinned appreciatively. "Thanks Beckett that means a lot. Let's not talk about the case though, okay?"

Beckett nervously bit her lip. "What do you want to talk about then?"

"How bout we talk about you? How have you been outside of work?"

"You see me every day Castle, I'm not much different at home."

Castle gave her a dubious look. "I doubt that very much detective. I know you have a life besides work. I'm just curious as to what you do for fun."

"To be honest, when I'm not working I don't do a whole lot. I do laundry, run errands, read books. I don't get a whole lot of time to relax, so when I can I take advantage of it."

Castle and Beckett continued on throughout the rest of the meal, quietly speaking and learning about what made each other tick. A few times during the meal Rick made some inappropriate jokes, earning a trademark eye roll from Beckett, but he could tell she was enjoying herself. She was laughing and smiling more than he had ever seen her, and her skin was positively glowing with happiness. She looked simply magnificent in the candle light, and Rick couldn't help but admire her.


Kate was actually enjoying herself. She had expected Castle to tease her about Will, or talk about the work the whole time, but he had kept the conversation delightfully refreshing. They discussed fond memories of their childhood, their favourite things to do on the weekends, and what season they loved best. Castle talked about Alexis and Martha, and what it was like living with them, as well as some of his ideas for the Nikki Heat book that he had wanted to run by her. All in all, the date was going well.

Kate was completely at ease with Castle, and found herself frequently getting lost in their conversations. Every time he leaned closer to hear her, or his hand brushed hers, her heart thumped hard against her chest. At one point he leaned across to fix a strand of her hair and she thought she was going to faint. The Castle who helped her solve cases made her heart flutter, but this Castle made her heart simply melt. She had only ever begun to experience this with one other man, and that man had just moved back from Boston wanting to start up their relationship once more. She didn't want to think about Will though. As Castle had put it, Will was her past and she needed to put it behind her and focus on her future; which could contain Castle if she chose to let him in.

As they made the ride back Kate pondered over her dilemma. She had seen an entirely new side of Castle tonight, one she was seriously considering making apart of her present and possibly future. He had been charming and sweet, and very understanding. He hadn't pressured her into anything, and had provided her with a simply delicious dinner. The more she went over it, the more she found herself wanting to be closer to Castle. She reached over during the ride and took his hand lightly in hers. He gave her hand a gentle squeeze before bringing it to his lips.


Soon enough they had reached Beckett's apartment door. Castle was standing as close he dared to Beckett, not wanting to cross the line that was beginning to blur between them.

"I had an amazing time tonight Castle. Thank you"

"Good, I'm glad. You deserved a night out, after everything that has been going on." Rick replied, with a rather pleased look upon his face,

Kate nodded thoughtfully. She took a deep breath in before turning to Castle to ask, "Rick, would you like to come in?"

Rick was taken aback for a second, but quickly recovered. Not wanting to blow any chance he had with Beckett he nodded and followed her into the apartment. They made their way into the bedroom, before Kate timidly brought her lips to his. Wanting to reassure her, Castle deepened the kiss, slowly tilting her back. She began shucking him of his jacket, and unbuttoning his shirt. Rick got as far as unzipping her dress before he stopped.

"Wait, Kate, are you sure about this?" he asked, scanning her eyes for uncertainty.

"Yes, Rick I'm sure" she replied, placing a kiss on his lips in attempt to continue. Rick carefully took her head between his hands and stared into her eyes.

"We've both had a lot of wine tonight, and you just had to deal with seeing your ex boyfriend again. I don't want to take advantage of you in any way Kate, the relationship we have between us is too important."

Kate sighed and looked down at Rick's chest. "You won't be taking advantage of me Castle. I do want this. Though tonight might be slightly influenced by the alcohol and my need for a rebound, it won't always be. I really like you Castle, and I want to see where this will take us."

Rick nodded in acknowledgement of what she had just said. "I really like you too Kate and I also want to see where this relationship will take us."

Kate smiled in relief. "I'm glad you agree Castle. Now hurry up and kiss me already" Rick didn't need to be told twice. He eagerly captured her lips in his, their tongues beginning to probe each other's mouths.

They quickly finished undressing before taking things to the bed. Rick began making a trail of kisses down Kate's neck, working his was down her chest and between her breasts. He expertly relieved her of her bra and began his ministrations on her breasts, licking and biting, pinching and twisting, causing her to moan in pleasure. Kate reached down to stroke Rick through the fabric of his boxers, eliciting a groan from deep within his throat.

It wasn't long before all garments were gone and Rick was teasingly kissing up Kate's thigh. "God Rick, just take me already" pleaded Kate, softly moaning as he drew nearer to her center.

Rick blew cold air across her heated sex before chuckling playfully. "Not yet love. You still haven't received the full Castle package." Kate's moans soon grew in intensity as Rick began circling his tongue around her nub, bringing her to an exquisite high. Just as she was nearing her climax, Castle pulled away.

Kate glared at him ferociously. "You better get over here and finish the job, or I'm going to put you in handcuffs and do it myself." she threatened.

Castle grinned mischievously. "Easy detective, let's save the bondage for next time shall we?" and with that he plunged himself deep within her depths. They worked slowly at first, gently rocking, discovering each other's preferences. As the desire grew heavier their pace increased until Rick was absolutely pounding into her, Kate rising to meet each thrust. They could feel their high's quickly approaching, and flipped over to speed up the process. Kate was now bouncing atop of Rick as he thrusted up within her. Kate steadied herself on Rick's chest as she reached her climax, screaming out his name. Rick followed with just a few pumps after and together they collapsed on the bed.

Slowly regaining the ability to breathe properly, the two turned took look at each other. Kate placed her hand upon Rick's cheek and smiled tenderly. "That was amazing Rick, thank you"

He grabbed her hand and kissed the palm softly. "Anytime detective, anytime." The couple buried down beneath the covers, turning on their side to snuggle into each other's arms, quickly falling asleep in their comfort.
