Disclaimer: I do not own anything from Castle, I just really enjoyed writing based off the characters.

"Well Beckett, if I'm not mistaken I do believe this means that I won our little bet," Castle said with a smirk of victory.

She turned to him to give a snarky response but settled for just glaring at him instead.

"Yah, good work Castle," she begrudgingly said.

"What? No sass? Just admitting defeat? I have to tell you, it kind of takes the fun away from my well earned victory."

"Exactly," she said looking him straight in the eyes making him falter for a second.

"Well... this means you won't be deprived of my charming company from now on. You did say you would take me back as your partner," his said recovering his composure.

"I suppose there are worse things," she said turning back to her paper work.

"Come on Beckett, as your reinstated partner, I insist on taking you out for a celebratory drink.

"Except going for a drink with you, Castle, would be under the category of "worse things" of which I was referring," she said playfully.

Castle sat down in the chair beside her desk leaning back with his hands behind his head. "Yeah who would want to go out with a ruggedly handsome gentlemen, sounds like quite a drag."

She glared at him, "You flatter your ego too much Castle. It turns out I already have evening plans of the best sort. I have a date with a glass of wine, a good book, and a nice hot bath," she said longingly.

Castle paused for a moment to let the image linger in the back of his mind, enjoying it immensely. "Far be it from me to drag you away from such a lovely evening. Especially since I know how much you are loving my latest book," he said trying to get a rise out of her.

Beckett looked at him startled. "No... it's not your book... it's... an action adventure," she said trying not to hesitate too much.

"Oh, interesting... and what's it about Beckett?" he smugly grinned at her.

She glared at him some more before giving up. "Fine Castle lets go,"

Beckett had said she would meet Castle at the bar because she wanted to change out of her work clothes first. The only trouble was she had no idea what to change into. She was back at her apartment standing in front of her closet, debating. She was worried of giving the wrong impression; not that she didn't want that idea to be given, but she knew she shouldn't. He was her coworker after all. However, she enjoyed the idea of shutting Castle up for once, and she knew the outfit she was looking at would do just that.

"Screw it," she said and started to change.

Castle sat at the bar with his drink in hand. He had no intention of getting drunk tonight so he just slowly sipped it. Suddenly he felt a tap on his shoulder and he turned around. He nearly spilled his drink all over himself as he took in the sight in front of him. Beckett was standing in front of him looking as sexy as ever. She was wearing a short black dress that dipped dangerously too low in the front. He took a bit too long just staring at her before looking back up and seeing her smug expression.

"What's the matter Castle? Didn't think I could let loose? I don't work all the time," She grinned and then turned to walk away towards one of the tables, leaving him to regain his composure.

He bit his lip as he got a great view of her ass as she turned from him. He took a deep breath to try and settle the rising feeling in his stomach as he went to join her at the table.

"So, Kate... it's alright if I call you Kate right since we aren't in a professional setting?" He said playfully.

She glared, daring him to press his luck but allowed him to continue. "Sure Rick," letting his name roll smoothly off her tongue.

He grinned before continuing on. "So why the constant tough exterior? You clearly don't have a problem showing this side of you." He took a moment to let his gaze wonder a bit.

"I want to be taken seriously in my line of work. I don't play around. I only let you see this side of me because lets be honest," she closed the gap between them making it hard for him to breathe normally, "you know full well that I could take you down." She said seductively.

Castle was completely tensed but not out of fear. He was getting so turned on from her being so close and well... so dangerously sexy. He had never experienced this side of her before and he definitely didn't want her to stop.

He wasn't going to let her have all the fun though.

"Well Kate, I'll be happy to let you spank me if I stop taking you seriously." he smirked at her confident that he had regained the upper hand.

Beckett bit her lip trying desperately to come up with a reply to top his. However, she was unaware that this had quite an unintended effect on Castle. His breath hitched in his throat as he was taken away by how damn sexy she was. He had to get some air... now! "How about I get you a drink?" he said standing from his chair very ungracefully.

"Yes a margarita would be nice." she said a bit taken aback.

Castle walked towards the bar to order her drink, taking the time to get his breath back. He didn't understand why she was suddenly loosening up in front of him. But he didn't want to blow it by scaring her away by being too forward.

The rest of their time, Castle was careful not to get carried away with flirting too much, but she was making it so hard on him. Everything she said seemed seductive to his ears but he convinced himself it was just his imagination and his dirty thoughts running away with him.

Beckett on the other hand was a bit frustrated that she couldn't get Castle to pick up her hints. She thought she was doing great at first, but he seemed to pull back after. She had made a decision that she wanted to make something of tonight with him, but she was running out of ideas of how to do it. Maybe he just saw her as his partner and nothing more.

It was starting to get late and Beckett was growing impatient. She was just debating if she wanted to risk being completely forward or not.

They eventually walked out of the bar to catch a cab. It was then that Beckett decided to seize her chance. She walked up behind Castle, pulling him around to face her. She gave him a second to register what was happening before pulling him towards her to kiss him.

Castle's brain seemed to short circuit at the touch of her lips against his. He was brought back to reality when she pushed up closer to him and put her arms around his neck deepening the kiss. He firmly wrapped his arms around her, melting into her embrace.

She finally leaned back to look into his eyes. He just stared at her blankly trying to get his thoughts to catch up with his words. But he didn't let go of her.

Just then a cab drove up in front of them. "I don't suppose you want to come back to my place for a bit?" Beckett asked him playfully.

"Oh god yes!" Castle said as he opened the cab door for them.
