Two pairs of legs were knotted together in heavy, labored exhaustion.

Almost three hours earlier, they had stumbled into her apartment, connected from the waist up, after the longest cab ride of their lives. Holding themselves in check half for the cabbie's benefit, and half for their own, they had almost accomplished the impossible task of not touching the entire ride. That was, until he made the mistake of reaching back to help her out when they arrived, and they had been falling off the edge ever since. One touch of their hands, intertwined at the fingers had sent them from teetering to downright plummeting into the place they were sure to go.

Three years of sexual tension in and out of work, and a nearly two months into taking their first step, the so-called honeymoon phase was still upon them, with some kind of unfathomable and unquenchable vengeance. It was like they were making up for lost time, and to say that they were going at it like bunnies would be a grave understatement. No surface was left untouched, especially at her place. The bed, (of course) the shower, the kitchen counter, the couch, the floor in the main room, the floor of her bedroom, the bathroom and the bathroom counter, the oversized chair, and (even though it's not really a 'surface') up against the wall (a personal favorite of Kate's).

Tonight, they hadn't made it as far as her bed, so the couch was going to have to do. She would have gladly gone for a round against the wall, because it was fast, and because that was how much she needed him, and needed him now. She had no idea that Rick's need to taste her was greater. They fell onto the couch, clothing flying unceremoniously this way and that. They had their nights when undressing each other was a tantalizing game of foreplay, but tonight was not one of them. The fire had escaladed way beyond that.

After kissing down her body, he had pushed her as high up the couch as she would go. Her long hair had fallen behind the couch as she draped her head over it when she arched her back. Her hips lifted slightly and he let out a low rumble of a chuckle at the question her body was asking before enveloping her with his mouth.

She had groaned out his name before she even realized what she'd done. Each time he tasted her was like the first. Each session was as if it were completely and totally different from the others. He knew exactly where to go, exactly what to touch, and exactly how to tease her very being onto the rickety edge of sanity.

He pressed his tongue flat against her, knowing the more surface touching her, the more her pleasure. She whimpered in need, encouraging him more. Suddenly there was more pressure, and his fingers were inside her, pressing upwards into that spot that would drive her absolutely wild. After swirling his tongue over her a few moments more, he simultaneously drove his fingers upward rubbing them as hard as he could against her, and sucked her into his mouth again and again.

She was done for. She exploded completely, hips bucking, letting out one of the most drawn out and ecstasy filled moans he had ever heard. He continued what he was doing, unwilling to hinder the waves that were short-circuiting her brain in any fashion. Finally, her shuddering slowed, and her arms, exhausted from holding herself up on the back of the couch, collapsed. She sunk down the couch as he sat up, eyes gleaming.

She sat there and just breathed for a full minute, almost to the point where Rick had thought she had fallen asleep. He moved to brush a strand of hair away from her face, and her eyes shot open, desire dark and eminent from deep within.

"I thought you'd passed out on me," he breathed, as she drew him towards her.

"Not on your life."

Before he could blink, she had flipped him, and they shot off into oblivion once more. She kissed him dizzyingly while grinding her hips into him so hard that she nearly went over again. He groaned into her lips, and she knew what he was pleading for, even without comprehensible words.

Without any real warning, (which was seeming to become a theme that night) she sunk down onto him, her warm weight enveloping him completely, and his eyes blinked open and then fell closed just as quickly as he moaned his appreciation. She rode him expertly, rolling her hips and experimenting with new angles. All he could do was groan ever so often, and open his eyes to watch the flawless beauty that was Kate Beckett on top of him.

When he had first called her 'extraordinary', he should have known it would have extended this far in definition.

Soon, he had them turned, her firm backside pressing against his stomach, pounding into her almost sideways, he hoisted her leg up and held it there under his arm so his length would press into her sweet spot with each hit. She was so close, shaking involuntarily beneath him, and he could feel his undoing was right around the corner. When he opened his eyes to look at her, finding that her hand had slipped downward, helping herself along, he became unraveled. He closed his eyes tightly and slammed himself into her, as she felt her let go. He wasn't far behind, tumbling after her. When they both stilled, they collapsed in a knot of arms and legs.

Eventually, they untangled from the couch and with renewed vigor, attempted to make it to her bedroom. They were unsuccessful, stopping in the hallway to use the wall as a perfect prop for her hand while he filled her again and again from behind. When her legs buckled at their second (or was it third?) release, he swept her off her feet and carried her to the bed, actually arriving at their destination this time.

After a few moments of damp, heavy breaths, she turned to him with a vixen-ish smirk.

"Oh, you got to be kidding me." Rick deadpanned.

All he got was a smirk and a pounce as she jumped him again, bouncing so forcefully on top of him that it took them only a minute or two before they were an inch from catapulting over the edge again. He looked her directly in the eye, and rolled them so they were on their sides again, this time, facing each other. She hiked a leg over and across his back, clamping it as hard as she could, drawing him into her with each thrust. His leg reached too, over her leg that was still on the bed, giving himself more leverage to pull out further, and in deeper. Each stroke was his entire length, filling her and emptying her in turn. His hand found a nipple, teasing it and stacking it on top of all the other sensations he was producing in her. His other hand was around her neck and buried in her hair, gripping her head tighter and tighter. One of her hands was gripping his backside below her leg, another means of holding him closer, and the other was in his hair, grabbing fistfuls as she moaned against his neck. He brought her mouth to his, and moaned 'Kate…' and her muscles clenched. From that moment, they were both gone. She shuttered and shook, riding wave after wave, his name spilling from her lips. He quaked, his hips moving of their own volition now, almost growling into her mouth as he followed her in suit.

They both stopped moving altogether all at once, letting out a single breath. Too spent to move, too exhausted to detangle.

"Kate," he finally whispered, her name dropping from his lips like a prayer. All she could manage was a groan.

After a few moments, she finally found her voice.

"Remind me to always do my bar trick for you," she mumbled, barely audible.

Because, in truth, that bar trick was the catalyst for the entire evening. The look he gave her when she presented the stem, tied neatly in a knot on her tongue was enough to make heat pool inside her, and promptly give him a look that said, "We need to go. Now."

And so, a knot had lead to a very different kind of knot.

One that exhaustion had make it impossible to untangle.

And in the morning, that knot would morph into another knot completely.

One that had been a long time in the making, and one that had becoming so tangled, so completely twisted together, that there was no undoing it.

After all, bodies were much easier to untangle than hearts.

Let me know what you think! Reviews are love, and I'm giving out a free glass of ice water with each one! ;)
