This prompt is from an Anon: A scenario where Kate told Rick she was 'ready for them/knocked her walls down' before 47 seconds in season 4 through some sort of romantic gesture/effort on her part.

Always. Always. Always. The word had come u more times in the month than all of the other times combined, but rather than it being similar to a short one-sided conversation when Castle said it, it was Kate. Castle had been happy with it, in awe really, the first time she said it. Like it meant something, and this time, it did. It was their declaration of love and trust. Their 'I love you' without admitting the truth, the inevitable.

Castle hadn't picked up on any of the little clues that Beckett was placing. Her small shoulder brushes when there is enough space for her to walk by him, and the excessive use of their word. But the one that made Castle wonder was the fact that she would wrap a her fingers around his, and hold them there for a few seconds while locking their eyes, showing nothing but a look that could be described as love.

He may not have known from those clues, but it was only a matter of time until he found out.

"Castle." Beckett grumbled, her breath halting every couple of seconds.

"Huh?" he looked up from his phone, immediately noticing the deep forest green color in her eyes. "Kate... Are you okay? You look flushed." she nodded, her eyes meeting his and darkening even more.

"I'm fine," she paused, "just, uhm."

"Kate-"

"Break room... NOW!" she stood up and entered the break room with a flourish, and started closing the blinds. It took Castle a moment to process what had happened, but it didn't take long for him to stand up and stride to the same door she disappeared through. When he entered, she was leaning against the table, looking as if she would pounce at any second. And boy did she ever, she pushed herself off of the table, slowly making her way over to Castle. Her leg wrapped around his, and kicked the door closed. The thud that the door made was synchronized with connection her lips made to his.

At first, he had no idea how to respond. He didn't know if she was just taking out the pent up aggression that she had gained since the beginning of the case, or if she was serious. He carefully placed his hands on her shoulders as if to say, stay here, but listen, and pushed her back slowly. Though the disappointment was evident on her face, she still listened anyway. "Are you sure?" he asked, his voice was strong but calm.

She glanced around the room on more time, and grabbed his hand. And what she did next, made him forget his own name.

She took his hand, expertly led it under the waistband of her jeans, and looked up at him with innocent, yet lust-filled eyes. "That's all for you, Ricky." she spat out.

"I-uh-how-me?" she kept staring at him.

"Always. It's always been you. This whole time." There it was... their word being used, but this time in a much more intimate setting. That was all the reassurance he needed before his mouth attacked hers. His tongue darted out to taste her lip, and when tasting wasn't enough, he bit down on her lower lip. Castle was rewarded with a moan from deep within her throat, and to release the sound her lips slightly parted. Castle took advantage of her pleasure and plunged his tongue into her mouth, swiping it over her teeth, gums, and finally her tongue. He slid his hands down from her waist, to the small of her back, and then move it down further to her ass. His hand landed on the top of the rounded part of her bottom, and he squeezed with all his might, earning another moan from her, which, in turn, sent waves of pleasure crashing down south, only making his pants tighter.

The need of oxygen became a necessity, so they pulled back and simply stood there for a few minutes, catching their breath.

"Wow..." she said.

"Yeah."

"I've never been this speechless, not even after earth shattering sex." Castle cringed at that, he couldn't imagine her riding anyone but him. Just then, Ryan burst through the door, breaking Castle from his fantasies while he eyed them suspiciously.

"Lanie. Is. Going. To. Be. Rich." was all he said before snickering and pulling the door closed again. All Castle and Beckett could do was stare off into the distance, they had a lot to talk about, but in the end they would make it work. They always did
