Disclaimer: No I don't own Castle. Shock!

A/N: So OK! This may turn out to be a giant mistake... An M rated chapter that accompanies 'In Reverse', follows immediately after the end of the "Maddie" chapter. Posted separately because it just wouldn't fit with the theme of that fic (chapter snippets with key critical events). Never written anything like this before, so reader beware: it might just suck. I finished early so here it is. Ever want to hear 'finished early' in the context of an M rated fic? Didn't think so...

Edit Note: Corrected some typos, and other minor fixes; broke the original chapter into three 'time stamped' segments. Apologies if that messes anything up.

Kate's Apartment: 10pm, Friday

Kate had backed Rick into her bedroom, a success in her mind, even if he was being a little deliberately troublesome. She pushed him back on to her bed, a place he had never been - not had any other man in this apartment; she had wasted none of her time in the past year on others, even before Rick would actually speak to her again. Her heart wanted what it wanted, and now she had it right in front of her.

She stepped back a little, and as he started stand held up a hand, "Wait. Watch Rick." She reached behind her to grab the zipper and lowered it, holding up the dress to her chest with her other hand. "I bought this dress for you Rick. I bought these shoes. This lipstick especially for tonight. I also bought this for you Rick." She dropped her hand then, allowing the dress to fall and pool at her feet, showing Rick the deep red lingerie underneath. Ricks's eyes widened, he had seen her in lingerie before, naked before, but those occasional were but stale memories compared to the beauty standing before him. He held out a hand to her, "Come Kate."

She threw back her head, exposing her throat to him, and laughed, "I intend to Rick. More than once." She stepped forward and placed her hands in his before moving them to her hips, and hooking their fingers in the thin band of her panties, "You've seen them now Rick, take them off."

They slid down, smoothly, like they wanted to be gone, no struggled effort to maintain balance as she stepped out of the fabric now laying on the floor. She stepped closer to Rick, guiding his hands behind her now, his mouth only inches from her.

Release! Kate felt it, a pressure released from around her chest, not just from the bra being gone, but from the joy of once again being naked with Rick, for the first time in years. As the bra fell away he ran his fingers across her upper chest, "I marked you here Kate. You told everyone you were mine."

Kate reached up to grasp the hand, pressing it firmly against her, where that signature had been only a week ago, "I did Rick, and if that's what it takes to prove to you how much I love you, I'll do it again."

Rick pulled her closer, seated on the bed his mouth was the level of her now braless chest, which he wasted no time taking advantage of. He dove in, lips latching on to a still soft nipple; feeling it tighten, grow and peak within the warmth of his mouth. Kate gasped as soon as contact was made, her knees beginning to buckle. It had been so long, with only age paled memories to tide her over in the shower or in her bed; memories and her own fingers, not the heat she was exposed to here with just his mouth touching, consuming.

Rick captured her ass in both hands, pulling her closer still, supporting her as collapse appeared possible; dragging her naked body between his spread legs and up against his clothed one. Her arms flew up, forearms resting on his shoulders, hands wrapped around the back of his neck. He continued to lick and suck, tugging her nipple one second, pressing it into her breast with his tongue the next; all the while she pulled his head tightly into her.

Rick looked up at her, mouth still occupied, to see her head tilted slightly back, eyes closed, and a simple blissful smile adorning her face. He kept his eyes on her, his mouth on her as he slipped one hand from behind her to lift one leg up, trying to bring it over his thigh, opening her to his gaze a further touch.

Kate felt him move, felt his hand move; she was still feeling every move of his tongue, every caresses of his lips like it was the first time once again. She let him lift her leg a little, before pushing away, shoving him to lie back on the bed.

"Your turn Rick. Too many clothes. Strip." She held out a hand to pull him upright, pushing him away from the bed and taking his seat, and position; legs spread wide, hands resting on her thighs.

"Rick? You stopped. Distracted?"

"Yes Kate, you drive me to distraction." Without removing an iota of clothing he stepped back towards her, bending lower to kiss, sliding a hand up her inner thigh to cup her, immediate feeling how wet she was. "You sure you need me naked to fix this Kate?"

Despite how much she wanted the simple stimulation to continue, to be held so intimately by him; she wanted him inside even more. Kate pushed his hand away quickly, to do so slowly would have been a torture she didn't think she could bear. So she pushed him away, "Naked Rick. Now."

She watched, couldn't tear her eyes away, didn't want to tear her eye away, as he unbutton his shirt, shrugging it off so she could see his naked chest, his forearms and biceps, which she wanted wrapped around her once again. Then the pants, dropping to the floor, to reveal in all their glory: superman boxers. She should have know. She licked her lips now, the boxers where not loose anymore, tented, they concealing what appeared to be a steel rod. She laughed at herself then, man of steel indeed.

Finally he dropped the boxers too and he stood before her naked, she lifted her eye slowly from his erection, seeking to meet his as he stepped towards her. Kate made a unilateral decision then, to much time had passed, to much unrequited longing; no time for fore play she just needed him.

Hitching herself up in the bed, she settled on her back, legs wide, knees up; hardly the most sensual position, not intended to tempt but simply to show everything. Understanding the need for urgency Rick climbed into the bed, up between her legs, pressed an urgent kiss on her lips and thrust inside her. Neither of them could prevent the gasps, the feeling of being together after so long simply extraordinary. Kate couldn't believe it, she almost came immediately; she new this was going to be quick, this time would be over fast.

Rick began to thrust, slowly at first, gently; she felt so tight, he knew it had been a while for her. Gradually Kate's arms crept around his neck rather than just her hands holding him other; the her legs wrapped around him, ankles crossed behind his back, meeting each thrust if his with an upward twitch of her own hips.

They both knew it was going to end soon, quickly, everything was just too intense, too stimulating. Kate was panting right along with Rick, thrust, pant, thrust, pant, gasp. On and on it continued until they both felt the crescendo building, burning through them; Kate tipped over first, but only by moments. Light exploding behind her eyes as they snapped closed, a dizzying sensation making her feel light headed. She struggled to keep her hips moving, but it wasn't necessary for long as Rick shivered and his whole, body went hard. She could feel him twitching inside her, an extra flood of warmth too and she welcomed it; again welcomed him within her.

After they had calmed, recovered somewhat they cuddled together, something they had both missed, just basking in the closeness and company of each other.

"Thank you Rick. Thank you for this."

"Kate, you know you never have to than me for this. I was hoping to deliver more than a wham, bam, thank you mam for you though."

"I don't mean the sex Rick, though that was intense; I mean for letting me back in."

Rick waggled his eyebrows at her, "Thank You Kate for letting me back in too!"

Despite herself she couldn't help but help but laugh at that, "Rick! I was being serious."

"I know Kate, but rest now, we'll talk serious things later ok." He pulled her back to his body and they dozed, relaxed, and drifted off to a temporary sleep wrapped up in each other.
