Half expecting her to move away, Castle stood up and walked over to the edge of the bed where she was sitting. She watched him, expectantly, her gaze going from his face to his arousal and back, and he knew she wasn't completely certain what he had in mind. Of course, he knew exactly what he wanted – had known for pretty much forever – and he used his foot to push her foot aside, which opened her thighs once more. He stepped forward until he reached the bed itself, and then dropped back down to his knees, using his thighs to keep hers open. Of course, if she moved away he couldn't stop her since his hands were still cuffed.

She didn't, though. She edged closer, until she was sitting right on the edge of the bed and then lay back, opening her legs just a little more in obvious invitation. One he was more than eager to accept. He lowered his head and pressed a kiss between her legs, his tongue licking out to taste her. She moaned and tensed, forcing herself to hold still.

"Yes…"

Castle smiled, but didn't raise his head. Instead, he took another taste of her, this one less tentative and far more invasive. Beckett whimpered, and this time she couldn't keep from writhing away from his mouth. It felt so good she couldn't have held still if her life depended on it. He chuckled, and moved with her as well as he could, his mouth clamped against her, now, and his tongue sliding along her slit hungrily. Beckett moaned again and again she writhed. This time she wriggled out of his reach, and Castle moved again, trying to get his head back between her thighs.

Beckett groaned and pressed herself against him again. He struggled against the handcuffs, slipping off the towel that was protecting his wrists from the handcuffs while at the same time following her along the bed as she writhed and wriggled against him, trying to get the most out of his attention but unable to hold herself still as the pleasure coursed through her every time he managed to get his mouth on her.

"Castle! More… please?"

He struggled frantically, and felt a sharp pain as his right hand slip out of the cuffs. With a lunge, he grabbed her by the hips and pulled her against his eager mouth, his tongue invading her and his lips eagerly searching for the part of her that he knew was most sensitive. She tried to writhe away from the pleasure, but he held her tightly, forcing her to hold still as he suckled on her, his tongue flicking across her clitoris and driving her over the edge as a wave of pleasure broke over her, and she arched against his mouth with a sharp cry.

Castle didn't stop just because she'd had her climax. He just slowed down a little as he licked her tenderly, pressing butterfly kisses along her inner thighs and giving her a chance to come down off the high. She sighed, deeply, and ran her fingers through his hair, holding him in place with a gentle touch. He smiled, pressed a final kiss against her clitoris and looked up at her.

"You're amazing…" he whispered.

She smiled, and put a hand on either side of his head and pulled him up and over her until she was able to press a few kisses of her own against his neck and chin and then his lips.

"You're not done, are you?" she asked, reaching her hand down along his chest, then stomach until she found what she was searching for. He gasped as her fingers closed around his erection, stroking him eagerly. "Finish it…"

He looked down at her, rocking his hips slightly as she held him, causing the best kind of friction.

"Are you sure?"

She smiled and nodded, guiding him to her still pulsing entrance and trying to arch up against him. The angle wasn't quite there, though, and she shifted under him. He chuckled again at her eagerness and willingness, and pulled her hips against him once more. This time, however, it wasn't his tongue pressing against her, and she gasped as he slid into her as slowly as he could manage without exploding.

When he was fully hilted, he stopped, his mouth coming down to claim hers in a heated kiss. She moaned into his mouth and he pumped against her gently once, and then twice just to feel her reaction.

She didn't disappoint. She whimpered in pleasure and arched against him, wrapping her legs around his hips.

"Castle..."

His control was gone. He pulled back and plunged into her again and again, gasping as she clutched his shaft with her inner muscles and used her legs to force him as deep as she could with every thrust.

"Yes!" his breath was coming in short gasps and he was panting against her neck, where he buried his face as he concentrated on each thrust, trying to go faster and still hold back long enough for her to climax again. "Kate!"

She wrapped her arms around him, her nails digging into his back as she once more felt the waves of pleasure starting to build up. He slammed into her, driving himself with a final thrust as he climaxed, grunting as he felt her body tense under him and then arch hard against his chest and stomach. She cried out as she felt him fill her, and held tightly to him as he collapsed on top of her, his breathing hard and raspy and their hearts hammering against their ribs so loudly the sound was almost deafening.

"Wow…" he whispered, trying to take some of his weight off her. She held him where he was, pulling his head down and kissing him hard. Her eyes met his and he smiled down at her. "That was amazing."

She nodded, running her finger along his cheek.

"Definitely."

He looked down at their joined bodies and pulled out of her with reluctance mixed with sheer enjoyment of the sight. He rolled off her and pulled her against his side, one arm draped over her, his hand brushing against her bare breast, teasing the nipple. Beckett didn't complain, but a red smear against her pale skin definitely got her attention. She caught his hand and frowned when she saw that his wrist was smeared with blood.

"Castle? What happened to your wrist?"

"I got tangled in the cuffs," he murmured, feeling the sting of the scrapes now that the sexual intensity had worn off a little. "It's okay."

She pulled away, sitting up and taking his hand to get a better look. His wrist was bloody from the handcuff. She reached for the other one, and found it just as bloody.

"Jesus. We need to get these taken care of."

"I'm okay," he assured her, trying to pull his hand away.

She wouldn't let go. Chagrined at the fact that he'd been hurt playing her game – unnecessarily – she was worried about him.

"I'm sorry, Rick," she told him, meaning it. "I didn't mean for you to get-"

He smiled, pulling her hand up and kissing it, gently.

"I'm fine," he repeated, firmly. "It was amazing and worth every scrape. Believe me."

She met his eyes, seeing the truth in them and couldn't help but smile as well. It had been amazing.

"We'll need to practice, I guess," she told him. "Apparently I haven't mastered the whole bondage thing, yet. Not if you managed to get loose."

He chuckled.

"Judging from your reaction, I think you should be the one that is tied up."

She hesitated, but then nodded.

"Maybe."

OOOOOOOOOOO
