This prompt is from : Castle and Beckett are acting all cute and teenagery at the precinct.

I'm just going to go off topic a little in the beginning with how Lanie found out, and, though, in a round about way, the prompt will be filled.

No other day had been like that one. Castle and Beckett had only been dating for a few months, and it was already difficult to hide their relationship. They had told Martha, Jim, and Alexis, but Lanie had guessed one day when she walked in on them making out.

It had been a long day, bodies were dropping like flies, and work had to get done. All Lanie wanted to do was go home, and drop into bed. Her plans were put on an immediate pause when she walked out into the main autopsy room from the small side room.

Castle had his back too her, and he was standing in the V of a woman's legs. The girl was sitting on the slab, and she was, without a doubt, grinding into Castle. Their moans and mewls were muffled by the other's mouth, but still very audible. There were hands roaming and tongues battling, but when Castle began to reach down to the apex of the girl's legs, she had had enough. "Castle, what are you doing making out with another damned bimbo? How many timeS do I have to tell you... Kate is in love with you." The two bodies froze at the sound of her voice. The three stayed quiet, until Castle broke the silence.

"Oh now Lanie... this beautiful bimbo is no ordinary bimbo. This one," he turned and made eye contact with Kate,"I love this one." Beckett gasped, and Lanie chuckled mockingly.

"You love this one? How can you love her? You have Kate."

"Yes I do."

"What?"

"I love you too." Beckett replied quietly. Not quiet enough that Lanie couldn't hear, though. Lanie knew that voice... It was... no it couldn't be,

"Kate?" Sure enough, she poked her head out from behind Castle and smile softly at Lanie. "You actually allowed him to make out with you? Here?" she nodded. Then it hit her. "You said you loved him."

"Yes I did, the only difference being I didn't use past tense. I still do and always will." she looked up at Castle and he wrapped his arms around her torso, completely enveloping her in a hug.

That was how Lanie found out, and of course, she had been going on about something that night, and it slipped out to Javi. He told Ryan, but it stopped there. Gates hadn't found out yet, and they wanted to keep it that way until they were one-hundred percent sure that they could still have a relationship without working together if Gates ever found out, and took Castle off the team.

They had been very good at keeping to themselves, but one day, Castle wore a cologne that Beckett had bought him. She told him that she bought it because the scent made her horny, and that he was only allowed to wear it to bed. He misplaced his other one, and reached on the top of his chest of drawers for any of his colognes, the only problem was he grabbed the one from her, and when she smelled it, she nearly jumped him.

That morning, Castle had a meeting at Black Pawn, so he got to the precinct a while after the rest of the team.

He strode through the homicide division, a cup of coffee in each hand, and he made his way to Kate's desk. She was tapping a pen against her chin, eyebrows furrowed showing her slight confusion. He placed the coffee in front of her, and sat down in his seat. She saw movement in her peripheral vision, but paid no attention to it. About five minutes later, when a group of people hustled to the elevator, the still air kicked up and sent the smell of Castle's cologne her way. Her eyes grew wide, and then quickly turned to slits as she glared at him.

"You didn't." she whispered.

"Didn't what?"

"You know exactly what I'm talking about."

He inhaled deeply, exhaling as a sigh, pondering over what she was talking about. Then it hit him, the woodsy scent flew through his nose. "I didn't."

"Oh, but you did. And I'm going to have to punish you for it." The deep coil of want appeared in her stomach when he made eye contact with her. She would have to be creative. She would have to tease him all day, just to make it more fun to relieve his need later.

Castle walked into the break room where Beckett was making a cup of coffee. "Here." she said, handing him the cup.

"Oh. Thanks? What's this for?" he asked, grinning.

"It's nothing... Just an apology."

"For what?"

"This." She walked towards him, and not only did she her shoulder come in contact with his, but her hand brushed past his manhood, making it immediately stand at attention. A throaty moan escaped his lips, and as she passed him, she squeezed his ass. He tried to lean into her touch, but she was too quick, and already at her desk when he came to his senses. Two can play at that game.

"You evil, evil woman." he said, as he sat in his chair.

"I'm sorry? I don't know what you're talking about." she gave him a sly smile and returned to her work. Since they didn't have a body drop, there was only paperwork to be done. Rick started fidgeting with the lone elephant on her desk, only stopping when she glared in his direction. "CASTLE." He jumped at the sudden outburst, but glanced her way in further acknowledgment.

"What?"

"Would you stop? I'm trying to focus, but you just keep moving your hand around in my peripheral vision, and it's distracting." The whole time she spoke, though wavering between forceful and teasing, she used the bedroom voice that she knows drives him crazy.

"I, uh, you know that... I'm going to go get some more coffee." he said after noticing he had downed his in the matter of a few minutes.

"I'm coming too." she countered as she got up.

"Seriously? I'm going to be in a small room with you again?"

"Maybe you'll like it this time." He couldn't tell, but she was having a hard time controlling herself. Ever since she had merely groped him in the break room, it was becoming more and more difficult to look him in the eye without feeling the need to touch him. And not in the nicest ways either.

He followed her to the break room. "Hey Kate?"

"Hm?" she turned towards him. He was closer than she thought, and when she faced him, he grabbed the backs of her thighs and slammed her down onto the counter. He sealed off his actions with a searing kiss. "Castle." she breathed. "Gates."

"I don't care, we can make this work no matter what. Yes, I do love working with you, but we can make it if I do get kicked off the team. I want to be able to do things with you. I want to take you out to book parties, meanwhile not worrying if our picture gets posted on page six. I want to scream to all of New York City that you're mine, and always will be."

"Fine." she leaped at him,clenching the back of his collar, while his arms slid around her slim waist. He locked his fingers behind her back, and they got lost in the moment, oblivious to any sounds... except one.

"It's about damn time!" Gates' voice squeaked from the door. They pulled back and attempted to straighten themselves out, but Gates walked through the door and put a hand on Rick's left shoulder and Kate's right. "You, Mr. Castle, are going to take the lovely detective home, and make her feel special." she winked and walked out of the room and into her office with a flourish. They stared at each other in disbelief, but soon broke out in laughter.

"That was so embarrassing," Kate moaned into Rick's shoulder.

"Buuut you have no oppositions?"

"Since when did you get good at reading minds?"

"Eh. It's in the blood." The couple chuckled and made their way to the elevator, little did they know, the whole precinct was hooting and hollering behind them, and only grew louder when Beckett slammed Castle against the wall as the doors closed.

A/N: I honestly hated this writing, the prompt was amazing, but I feel like I'm losing my touch. I'm better at describing things than writing stories. Sorry it took so long to update, I'll try to get better at that. Please review, request, fave, and follow.

Thanks,

Sarah
