A/N: I never intended to write about Kate's hinted payback at Castle for handcuffing her to the bed. Ever. I thought it was nice just leaving it where it was. But then reviews started coming in and my mind changed. When I sat down to write this final part, everything fell into place as far as setting and such goes.
Disclaimer: Goodness, did you see the adorable tweets between all of our writers today? I wasn't among them.
He had fallen asleep at his desk. That's what happened when his characters refused to shut up for the amount of time it took to make dinner. It hadn't occurred in a while, but he really hadn't been writing lately so that would account for the lack of opportunity for desk-naps to take place.
Castle hadn't realized how late it was until he cracked open one eye and saw the city lights outside the window, illuminated against the night sky. His hair was in his eyes and he went to brush the stray locks back but found his hands stuck. Not just stuck to the desk from the light sweat on his forearms but tied down to the arms of the chair.
"What the…?"
"Funny. I had a similar reaction, didn't I?" The humor that laced her voice had him glancing into the darkness to find the source of the sound. She solved the problem for him, circling around so her figure, clad in only her underwear, was outlined by the lights outside the window.
He wiggled his hands, testing the strength of the knots though he knew she wouldn't have left them loose. "Staging your own interrogation, Detective?"
The finger that trailed down his neck was a shock, as was the laughter that pealed out next to his ear. "You could say that." Her lips took the place of her finger, pressing soft kisses along his jawline. "Just think of it like this, Castle. Payback's a bitch."
"And you had to tie me up to exact your payback?"
"Yes." Her arms were around his neck, working on the buttons of the pale blue dress shirt as her chin rested on his shoulder. "You should be thankful that I'm using something that won't leave marks around your wrists that will have co-workers asking their origin."
"Seriously?" He was trying to distract her, to give him enough to time wiggle the knots looser on the fabric encircling his wrists. A glance down revealed exactly what she had used to bind him down. "You tied me up with my own scarf?"
Her nose rubbed against his neck as she slipped her hands under the fabric of his shirt. "Yeah. I did. Turnabout and all that. You used something of mine, I use something of yours. Though I don't know why this one was hiding in the back of your closet; I've always loved it."
He turned his head, trying to capture her mouth in a kiss but she pulled back coyly. "Ah ah ah." She placed a kiss on the tip of his nose. "I don't think so."
Castle groaned when she disappeared from behind him. "Kate…"
"What, Castle?"
He hated how calm her voice was while his shook the tiniest bit. "This isn't fair."
That laugh again as she sat on the edge of his desk, her feet dangling above the ground. So close yet so far. "No one said anything about fairness, Castle. You should have thought of that before you pulled your own little trick on me." Her bare foot traced a path up his shin and over his knee, coming to rest on his thigh. Then it trailed back down as she stood up. Kate leaned her hands on his thighs, her lips an inch from his. "You ready for this?"
The quick swallow after he licked his lips told her the answer was 'no,' but she pressed a kiss to his mouth anyway. "Good."
Using his arms as leverage, Kate slipped her feet through the arms of the chair so she was sitting in his lap. Her bra-clad breasts brushed his chest and his hands twitched up, trying to pull her closer. "Sucks, doesn't it? Not being able to join in."
"Seriously," he muttered. "Remind me not to do that trick again."
She added to the torture by catching his lips in a kiss that had fire shooting down his body, brighter and hotter where her skin touched his. This time, she let him join in, his head pushing forward to deepen the kiss, his tongue tracing her bottom lip. Her hands gripped his shoulders, shoving the fabric of the shirt as far off as it would go. "God, I did not really think this out," she moaned against his lips when the shirt caught on his biceps.
"As Tim Gunn would say, 'make it work.'"
Her fingers curled around the edge of the lapels, rubbing them between her fingertips. "I hate to rip it. I do love you in blue." She scraped her fingernails down his chest as she kissed him, nipping at his lips. She felt his fingers straining toward her back and she inched out of his reach. "You're so impatient."
His voice vibrated against her throat as he nipped at it. "Can you blame me?"
"Not really."
Then she was gone. He missed her heat pressed against him but her fingers appeared on his chest, walking their way down to the waistband of his pants. She unbuckled his belt, pulling the strip of leather from the loops on his jeans, letting it slither to the ground. Kate was working slowly on the button and zipper, flashing a quick smile up at him.
As she hooked her fingers around the waistband of the jeans, Castle let his head fall back onto the chair. "Kate, you really need to move faster here."
Since the once-gentle curl of desire that had been sitting in her stomach from being in charge this round had caught fire, Kate had to agree with him. He lifted his hips up enough for her to pull the clothing down. She stepped out of her underwear, kicking it into the pile of clothes.
"This would be easier if you untied my hands. More time-efficient for both of us to do this together."
"Wouldn't you love that," she laughed as she let her lips dance up his stomach until she reached his lips. "Unfortunately, it's not going to happen." She still stood between his knees, teasing him with light kisses across his face. Kate felt one of his fingers brush against her thigh and shivered from the shooting of electricity up her body. She gasped into his mouth and he took the chance to gain a small bit of power by darting his tongue into her mouth. She swayed forward, catching herself on his shoulders. "That's cheating."
"Didn't you say something about things not always being fair?" He was pleased with himself, using her own words against her.
Kate slipped her feet back between the arms of the chair, her center so close to him. "Did I?" She leaned forward, brushing her nose against his before capturing his lips between her teeth, nibbling on them lightly before kissing away the sting. "Then I guess it would be okay to just leave things as they are right now. All things being unfair and that."
Castle had been twisting his wrists, a futile attempt to free himself, but her threat had him trying even harder. "Beckett, you leave now and I swear I'll make you regret it."
"Back to Beckett, are we?" she sighed, her forehead rubbing against his, her hair a cool blanket over his chest. "Seems like a step back, doesn't it?"
"You're a minx, Katherine Beckett," he growled against her cheek.
Sitting back, she bit her lower lip, a smile pulling at the corners of her mouth. "I'll take that as a compliment."
"It was meant as one." God, all he wanted to do was run his hands over her. He didn't even need to have sex, but he did need to touch her. "Could we get the main production or is there more torture involved beforehand?"
She released her lip to grin. "No, I think we can move on."
He resisted the urge to say "good" but only because Kate pushed forward, her forearms on the back of the chair. Her breasts, still covered by the plain navy blue of her bra, ghosted by his face before she sat back, taking him inside her with a soft sigh.
Their kiss this time as gentle and sweet, a counter to the need to do more than just let their bodies connect. He broke off first, his breathing labored as he clutched the arms of the chair.
Then she started to move, slowly, her fingers playing with the wisps of hair at his neck as she let her forehead balance on his. Their breaths mingled as she continued the steady motions, driving both of them crazy with the constant rhythm.
Just when she started to feel close to breaking, she rocked forward, her hands braced on his chest.
"Untie me," he groaned. The need to hold her, to touch her, was unbearable. It was his breathless plea of "please" that had Kate pulling on the end of the striped scarf. His left hand flexed before it gripped her hips. Her fingers shook as she fumbled with the knot on his right wrist so he reached over and helped her loosen the knot enough to pull his hand from the soft cloth.
He stood up, swiping an arm across the desk to clear it before he balanced her on the edge. The sudden change in angle had her biting down on his shoulder to stifle a cry. She had to place her hands behind her to stay upright, their chests pressed together even as he continued the erotic slide of their bodies.
Kate could feel the curling of release starting in the middle of her stomach, her fingertips digging into his upper arms. "Castle…" She wanted to hold out, to make him let go first, but that plan was quickly spiraling out of control.
"I know Kate," he said as he pressed hot kiss against her mouth. "Just fall for me."
"No," she managed to gasp. "You first."
He let go of her hips with his right hand, let it slide between their bodies. "How about together?"
The moment she nodded against his shoulder, he brushed his fingers over her. Just as Kate gave a shuddering gasp, he pushed completely into her with his own groan.
Kate was the first to regain the ability of speech after what seemed like an hour. With her forehead still resting on his shoulder, she muttered, "Now we're even." She managed to lift her head up and kiss him softly.
A/N: This is it. No more restricting the other's hands. As Kate said, they're even. And using that drool-worthy scarf was a genius stroke on our detective's part, wasn't it? Now we have another reason to be drooling over it.
Reviews, as always, would be lovely. At least, while we still have words before Cuffed airs.
