Castle kicked the door open with the heel of his foot and stepped into the darkness of the factory. They located their subject of the Grant Gallagher case all the way to this warehouse. Slowly, the team stepped inside minus the writer because she was told to stay in the car and not to move by Castle.

The team moved silently about the warehouse, fanning out to cover more area. From the car Kate saw a movement a window, someone she knew wasn't anyone on the team. Beckett drummed her fingers nervously on the dashboard. Should she go in? That would go against Castle's orders though. Stay in the car, Kate thought. There was a movement again in the window, and before she knew it the door was flying open and she was out of the car in a heartbeat.

The warehouse was dark, but Beckett saw the flash of the suspect again. She followed after him, moving stealthily.

Elsewhere, Castle saw a movement; somewhere towards the back and he followed, gun at the ready.

A clash sounded, Beckett looked down and saw she had kicked over a bucket. A classic Kate Beckett move. The suspect jumped around and found Castle right behind him. The suspect whipped out his gun and had it pointing straight towards Castle. Kate's heart froze. He was going to be shot! Beckett, without thinking, ran and tackled Castle pulling him out of the shooting range. Arms and legs got tangled together as they fell clumsily to the floor.

"What the hell?" Castle yelled. The suspect made a move to leave which caught Castle's eye. "Esposito! Ryan! In the back!"

His partners came running out of the dark and caught the suspect before he could reach the door.

Beckett was lying over Castle, both of their chests rising and falling quickly. For the second time in one week, he could feel every contour of her body as she looked down at him with apologetic eyes. She was beautiful. Her hair was spilling out in front of her; she was biting her lip out of nervousness.

Reality broke in. "What were you thinking?" Castle yelled. Beckett sat up, her hands resting on his knees.

"The gun! He was going to shoot you!" She retaliated staring down at his big blue eyes. His face was twisted with anger, but he was still so handsome. How could he do that? Be so intense, look so angry all the time, and still be the most beautiful thing. She mollified as she looked at his lips. "I'm so sorry. I know. It was irresponsible for me to do. I just couldn't watch you get shot."

Beckett's head dropped and Castle could no longer see her face. He had a sudden urge to look into her eyes. He needed to see her. Castle sat up and leaned forward, and Beckett picked her face up and suddenly they were inches away from each other again. If Castle leaned forward just a little more and she did the same their lips could touch.

"I…" Beckett started, but lost all her thoughts as she looked at his lips for about the millionth time. Her heart was racing, and she was pretty sure he could hear it. Castle was overtaken, he was engrossed by her. He had never had these feelings towards any girl before. He had dated sure, but it wasn't ever serious because he wouldn't let it get that far.

Cherries. That's all he could think of. Cherries and Kate. Yet again for the second time this week, she was surrounding him. He had to kiss her. He completely forgot why he was angry in the first place. Her lips parted, and her breathing was picking up pace. Castle tilted his head a little farther; there wasn't even enough space between them to think.

Someone coughed behind them. "Guys… We gotta go," Esposito interrupted. Esposito didn't want to say anything, neither did his partner but they knew Castle would be stuck to paperwork for months if Gates found out about the PDA during the job.

Realization flashed across both of their faces about what almost just happened. Beckett jumped up and backed away from him. "That… We… I…" But no words were coming out. She looked at Castle one last time than walked out of the warehouse.

Castle ran his fingers through his hair, and stood up slowly. Ryan and Esposito looked at him cautiously. "Not a word about this, to anyone." He stated.

"We got your back bro." Esposito nodded at him and Ryan shook his head too.

It had been a little over a month since the day in the factory, nobody mentioned it. Beckett took a few days off afterwards, and although Castle tried not to think about it, he was worried that she would never come back. But she did, and she laughed and acted like nothing ever happened. Yet again, that's what Castle wanted… But he couldn't understand why he felt so disappointed.

A new body dropped last night, and Castle already knew it was going to be a long day. They'd been chasing people around for most of the morning and it had all been dead ends. Nothing made Castle more irritated than dead ends.

Castle's phone rang as they were standing at the board trying to come up with something.

"Castle" he snapped. A quick explanation was given and then a quick goodbye.

"We have to go to see Lanie." And then he was already off, heading to the car, Beckett not far behind.

The drive was short and quiet. Castle focused on the road and Beckett only looked out the window.

"Detective Castle. Beckett. What a pleasure seeing you today." Lanie greeted unenthusiastically.

"Yes, always a pleasure." Castle said, his tone always holding that seriousness.

Lanie wasted no time on her findings of the body. Alcohol and drugs were found in her body, and stab wounds on her stomach.

"Beckett… will you stay for a little. I have something important to tell you." Lanie said as she ended her description.

"If this is something about the case, than I feel as though I should be present seeing that I am the cop." Castle stated using his cop voice.

Lanie gave him a disapproving scowl, and Castle immediately knew he had gone too far. He faced murderers of all kinds constantly, but he knew Lanie was nothing to mess with.

"Detective Castle, I will ask you to wait in the car. I will send Kate up in a few minutes."

Rick nodded and headed out the door before he was chastised even more.

"So…" Lanie trailed off, and Kate looked at her confused.

"What?"

"You know what I'm talking about! Your boy! What's been going on with you two?"

"Who…?" Kate asked confused.

"You and Castle."

"What? No! Castle and I have nothing going on between us!"

"Are you really that blind to it? Everyone sees what going on between you two, girl."

"There is nothing! There won't be in a million years because all he ever thinks about is his job!"

"Kate. I see it every time you guys are here. It's like electricity that burns between you too. It may seem like all Castle ever cares about is his job, but really since you came to shadow him, he has been different. He smiles all the time when you are near him. And you guys lean towards each other. Do you know that? Even today, you guys did it. It's like you are drawn to each other. Like you gravitate towards one another."

"Lanie. You are so wrong!"

"No girl, no I am not. You guys are good for each other. Perfect actually. He is so uptight, you would balance him. At a few company events, he would bring a girl. But it never seemed serious. Castle doesn't have serious relationships. You won't admit it to yourself, but you like him. The way you guys banter, it's like ying and yang."

"You're forgetting that his job is all that matters to him. I know that. And my job is important to me. So even if there were to ever be anything, and I'm not saying there is, if it ended badly I wouldn't be able to shadow him for my books. He won't ever overstep his job though. Isn't it obvious, he would never give me a chance." Kate explained and Lanie just shook her head.

"You're wrong. Just take the chance. You have to make the first move, because Castle won't."

"Whatever you said Lanie." But what the M.E. had said followed her all the way into the car.

Castle looked at her questioningly. "So, what was that about?"

"Oh… Esposito troubles. Girl talk." Kate felt her heart beating, she felt like Castle knew everything they talked about.

"Ah, gotcha." But Castle knew something was off, the way her fingers drummed against the dashboard and how she was biting her lip again. Something she only ever did when she was nervous.

The conversation was dropped and no words were said during the duration of the car ride back to the precinct.

"A bar?" Castle asked, "That's where our killer works?

"Yeah, a bar off of Washington and Broad. He'll be there tonight. Bouncers can spot cops from a mile away, and you'll never get in if you look like you have a motive. You have to go in undercover." Ryan said, and everyone's eyes shifted from Beckett to Castle and back to her again.

"What?" She asked at all the attention. "I don't understand."

Castle sighed and Esposito took the liberty of explaining. "You and Castle have to go in tonight. As a pair. A couple."

Castle shook his head. "No. I refuse. She isn't a cop and she is like a child! She'll try and jump on the murderer at the first sight of him just like in that warehouse. It's not going to work; she is going to screw the plan up!"

"It's the only way." Gates chimed in, although normally against anything dealing with Beckett, she agreed with the rest of the team.

"No. I will absolutely not let this happen." Castle shook his head even harder. But he could tell he had no chance.

"I can do it." Beckett said softly. "I can do this."

Everyone looked over at her. She was looking at her feet, biting her lip. Take the first step, she repeated to herself.

"Good, it's settled." Gates said with a clap of her hands as she walked off. Everything was silent as the team waited for any more of a reaction from the two.

Castle sighed. "Meet me here. 8 o'clock. Dress club appropriately."

It took her forever to find something to wear. She had plenty of clothes, but she just couldn't make up her mind. She wanted to dress club appropriately like Castle had said, but she felt everything was too much.

Kate settled on a navy blue dress, it came stopped at mid-thigh and the back was completely open. In the back of her mind though, she secretly wanted to impress Castle.

Castle was standing outside when the cab pulled up. The door opened and a pair of long legs slid out. Rick couldn't breathe. She stood up and Castle went instantly hard. Her dress was blue, and long stiletto heels on making her legs look even longer and sexier. The dress had a v-neck cut and it ended right before her breasts making Castle want her even more. Her hair fell in loose curls that framed her face and Castle couldn't have thought of anything more beautiful. He wanted to take her to his house and never let her leave. He would never let her leave his bedroom.

Kate saw Castle looking at her from head to toe and she felt naked. The way he looked at her, like an animal.

"Kate." He smiled, as he stuck his arm and she hooked hers into it. "You look… exquisite."

"Yeah, you're not so bad either." Who was she kidding? He had on this deep red shirt with the first two buttons undone. Kate could see his muscles through his shirt and it made her knees weak. He had a black jacket over his dress shirt and black slacks on. His hair was messed up like it was every day from the constant running of his hands through it and a few pieces of hair fell limp over his forehead. His blue eyes blazing and staring right at her.

They arrived at the club and before they even went inside the music was blasting. A bouncer took one look at Beckett and let her in immediately, Castle wanted to smash the guys face in for looking at Kate like she was meat. But yet again, his own thoughts were probably worse.

The pair entered the club and it was packed wall to wall of people. Barely enough room to think. Castle scanned the room for the suspect and at first glance couldn't spot him.

Rick yelled something over the music. "What?" Kate yelled back. Rick leaned in and tried again "I can't find our guy; I'm going to grab us some drinks. I'll be back. Don't do anything stupid. And please try to blend in." His breath was hot against her ear, and his the stubble of his chin coarse against her cheek. Her knees went weak and her heart pounded. It seemed as though Castle lingered by her ear longer than he needed too, but Kate wasn't complaining. She nodded in response, for fear her voice wouldn't work.

Castle walked off, but had to stop himself multiple times from turning around; throwing her over his shoulder and taking her out of the club to somewhere they could be alone. He grabbed the drinks, cursing only a few times at the bartender for not going fast enough. He practically ran back to where he left Kate last, 1) out of fear she had done something stupid and 2) because he had to be near her again, to feel that electricity again.

He spotted her, and he cursed himself for leaving her alone. She was dancing, but that was hard to classify as dancing, it was more that she was trying to kill Castle from sudden blood rushes south of the border. Her hips were swinging back and forth and she was running her hands through her hair. All the guys around her were drooling, staring at her ass just like Castle was.

He set the drinks down, not caring that he had just paid for them. Rick pushed through the crowd of people to where she was and cut in with the guy who was dancing with her. "Mine." He snapped. And the dude went to say something, but Castle gave him the most terrifying look.

"What happened to the drinks?" Kate asked, unaware of the effect she was having on him.

"Lost them." There was no room for talking; Castle had to have her up against him. Like the moment in the streets, or in the factory. He grabbed her tiny waste and brought her too him. They were dancing together; actually it was more like the closest thing to heaven for both of them.

Her hips moved side to side and all Castle could smell was her. She was surrounding him but yet she didn't seem close enough so he pulled her tighter against him. Kate felt his hardness against her back. It was hard to ignore. She wondered how she was still standing, she felt like she was going to collapse at any minute. His cologne was intoxicating. Kate wondered what he used, because it smelled like him. It smelled like Richard Castle.

Make the first move, she thought. Beckett could hear Lanie yelling at her to at least do something! She had too! He wouldn't be hard for no reason, would he? Did Kate really have that effect on him? The way he acted around that other guy really showed something too. She would never know though if she never tried. Kate had to at least make a move, and if it didn't work out she'd deal with it later. But as of right now she wanted so badly to kiss him, ever since she stepped out of the cab and saw him eying her furiously.

1… 2… 3… Kate turned around and looked at him. His eyes a glow with desire staring piercingly at her. She glanced down at his lips and her mouth parted and her breathing was heavy. Beckett bit her lips from nerves, she counted to herself again then leaned forwards and gently brushed her lips to his.

Castle lost it. All the desire he was trying to hold inside came tumbling out. He attacked her lips, hungrily demanding entrance to her mouth. She was like heaven, like snow on Christmas morning. His hands went to her back and were moving to wherever he could reach, but not the places Beckett wanted him most. Her hands flew to his hair and were running her fingers through the strands. Her lips were like silk and Castle couldn't get enough.

She moaned against his mouth which set him off further. It became a battle of teeth, tongue and lips. He pulled her as close to his body as he could. Castle broke the kiss when the battle for air became too much and Beckett was panting. He trailed his own little kisses down her neck and started sucking just above her collarbone, Kate moaned again. Castle should win awards for what he could do with those lips.

She had to have them on hers again, grabbing his face she pulled him back to her lips and again the battle started. Castle was seeing stars, and it was only a kiss. Kate put her hands around his back and was scratching lightly, it was driving Castle crazy. It felt like he couldn't be as close as he wanted. Kate's whole body was against him, but for some reason it still was close enough. Rick dropped his hands to her ass and pulled her closer. Kate gasped and realized that they were in a club, and Castle was doing his job.

"Rick…" Kate said breathlessly. She was trying to stop, trying to help things get sorted out, but he took it as a cue to keep going. He dropped his head again making an assault on her neck for the second time. This time finding a spot below her ear that drove her crazy.

"Rick." This time she was moaning his name and so he continued, in his own heaven, and so was she. But she had to stop; she knew Castle would be in trouble if he didn't catch their guy. With all her strength she moved her hands back to Rick's chest and with as much authority as she could muster in that moment she called his name again. "Castle!"

His head lifted and he looked straight at her.

She was still panting, and she was wet, but she knew what she was doing was right, no matter how good being wrong felt. "God… that was… But the case… we-"

Recognition flashed across his face and Detective Castle was back. He stepped away from her like she was poison. He felt sick to his stomach. He just made out with Kate. And God it was good. Better than anything he had ever felt. Castle lost himself, that's how good it was. Kate Beckett made the famous New York City cop forget his own surroundings while on the job.

"Shit." He mumbled, and he was off looking for their guy. The taste of Kate still on his lips.
