THAT PART


Castle looked down at their entwined hands, and was struck by how right it felt for Beckett to be the one leading him into his own bedroom. He’d been following her lead for four years now. That dynamic worked well for them when solving cases, and he hoped that some of that would carry over into the bedroom as well, but in this moment he was much more focused on how amazing it was that she’d chosen him over her personal vendetta.

Once they were standing by the bed, Kate turned to face him. He put a hand on her back to pull her body up against his, and kissed her. He felt her fingers unbuttoning his shirt, and they broke apart long enough for her to slide it off his shoulders. His shirt cascaded to the floor. She pulled hers off, and tossed it next to his.

He leaned in to kiss her again, and felt her hands on his chest. Her fingers gently pinched both of his nipples at the same time, and he moaned into their kiss. He used both hands to unsnap the back of her bra, and slipped the straps off her shoulders. She quickly pulled it the rest of the way off, and dropped it. He stepped back to take a good look at the breasts he’d imagined thousands of times over the years. They were ample, considering how thin she was, and her nipples were invitingly perky.

“So beautiful,” he said reverently, “Perfect.” He used both hands to cup her breasts, and ran the pads of his thumbs back and forth across her nipples.

She closed her eyes, and let her head tilt back, to enjoy the sensation. While his hands were busy, he leaned in to kiss her exposed neck. He felt her fingers unbuckling his belt, and within seconds his pants slid down his legs. He stepped out of them and kicked them aside while licking a spot on her neck that made her shudder. He gently sucked on that spot, and rolled both of her nipples between his fingers.

Her hands rubbed down his sides, and over his boxers to squeeze his ass. Breathlessly she whispered, “Do you remember what you said the first time I took you to an interrogation room?”

His fingers and tongue stilled for a second. He lifted his head from her neck, looked into her eyes, and said with a grin, “Yes.”

“Did you mean what you said?” she asked, squeezing his ass a little harder.

He leaned down to whisper directly in her ear, “I’d be happy to let you spank me, anytime you want to.”

The words mixed with his breath against her ear made her pussy throb. He trailed kisses along her jaw, while she said, “You have no idea how often I’ve wanted to smack your ass.”

He straightened up and said with smirk, “I’m guessing it’s at least twice a day.”

She chuckled. “More like twice every hour.”

“Then I must have been doing something right,” he answered with a raised eyebrow.

She raised her eyebrow to match, and slid her fingers into the waistband of his tented boxers. She carefully lowered them to mid thigh, and said, “Well, then you should be rewarded for your bratty behavior.” She gently snapped the elastic of his boxers against his thigh and said, “Take those off along with your socks.”

She took a step back and watched him do what she’d asked. Once he was completely naked, he stood still and waited for further instruction. Her eyes raked over his body, and she hastily kicked her heels off, undid her slacks, and let them fall.

“Your legs are exquisite,” he said, reaching out to run his fingers across the lace of her black panties that matched the bra on the floor.

Smiling at the complement, she said, “I’d like to see you on your hands and knees in the middle of the bed. Would you like…” he darted to the bed and got on his hands and knees before she could finish her sentence. “…that too? I guess that’s a yes.”

“Yes,” he said, looking back at her over his shoulder, and shifting his knees so they were roughly a foot apart.

She got on the bed, kneeled at his left side, and put both her hands on the sides of his face to make sure she had his attention. “If you don’t like what I’m doing, you tell me. And anytime you want to stop, just say stop and I will. Got it?”

He lifted one hand from the bed, put it on the back of her neck, and pulled her in to a soft kiss. After a couple of seconds, he pulled away, looked her in the eye and said, “Beckett… Kate, I doubt there’s anything that you’d enjoy doing to me that I wouldn’t like, but I promise to tell you if I want you to stop.”

“Good,” she said, and let go of his face. He put his hand back on the bed, but kept his head tilted towards her to see what she was doing. She scooted down towards his lower half, got up on her knees, and put both her hands on his back. She rubbed them down over his ass and thighs, and then back up again a couple of times. Then she settled her left hand in the center of his back, raised her right hand in the air, and gave him a sharp slap on the right side of his ass.

He closed his eyes and a little moan came out of his throat.

She rubbed the spot and said, “Was that a happy noise?”

“Yes,” he said, and opened his eyes to watch while she put a matching slap on the left side. He moaned in appreciation again, arched his ass up a little higher and said; “It’s perfect. It’s just how I imagined you’d spank.”

“Yeah?” She put another slap just under the first. “How’s that?”

“Straight to the point. No fooling around.” Another smack landed, and his cock twitched in response. He closed his eyes and said, “It’s exactly right. Not too hard, and not too light.”

She noticed the first hints of pink on his ass, and a rush of desire shot through her. She wanted to see that same color pink on every inch of his ass and upper thighs, and spanked faster.

He gasped, and moaned as she methodically covered the entire surface of his rear with pink handprints. When his shoulders and back muscles started to tense up with the strain of staying in place, she stopped for a moment to rub at the sensitive skin.

“Still good?” she asked.

“God yes, so good,” he said, arching into her touch. He opened his eyes and looked back at her to explain. “I love how serious you are.” He saw her eyebrows draw together in confusion, and tried to clarify. “When you’re working, you’re always determined and focused. You spank with that same determination. You spank like you mean it. I just hope you’re liking it as much as I am.”

“I don’t just like it.” She got off the edge of the bed, took her panties off, and put them next to his hand so he could see the large wet spot that had formed while she spanked him. “I love it,” she said while crawling back to his side.

“We’re always better together,” he murmured, “no matter what it is we’re doing.”

She put a hand on his back, and said, “Ready for another round?”

“Absolutely.”

“I’d like you on your elbows, so that your spankable bottom is the highest point on your body.”

“That’s so hot.” He mumbled, and leaned down on to his elbows.

With a grin, she started spanking him again. She started at the very top of his ass, and slowly inched her way down, overlapping the swats and alternating sides until she got to his upper thighs.

He moaned with each smack, thrusting his hips, trying to get some kind of friction for his bobbing cock.

She stopped, and trailed her fingertips across the spanked area. She ran them around his inner thighs, and then cupped his balls in her hand.

“Oh God.” His fingers curled into the comforter and held tight.

She rolled his balls gently with one hand, and used the other to put a firm smack on his right sit spot. He groaned loudly, as she slapped the left side.

Ten slow spanks later, Castle gasped out the word, “Kate?”

Her hands stilled, and she said, “Too much?”

“Not exactly, I’m just not going to last very long if you keep it up.”

She ran both hands over his pink ass and up his back as she shifted towards his upper half. She whispered into his ear. “Condoms?”

“Nightstand.” He reached across her to open the drawer. He grabbed a condom, tore the package open, and rolled it onto himself.

Once it was in place, he moved to kneel in front of her, so that they were face to face. He wrapped one arm around her waist, and sought out her tongue with his to taste her again.

While their lips were locked together, Castle pulled her down to lay on her side next to him. He nudged her onto her back, and kissed his way down her neck and chest until he reached a nipple. He started to gently suckle on the left nipple, and slid his hand down past her stomach to dip his fingers in between her legs.

When his finger slid across her wet clit, her breathing became more rapid, and she spread her legs wider to give him access. He ran a finger rhythmically back and forth across her clit, making her groan in response. After getting several moans and gasps out of her, he moved his mouth to the other nipple to suckle.

She ran both of her hands through his hair, and murmured, “You’re so good at that.”

He kept his finger moving, but lifted his mouth up off her nipple to say, “You sound surprised.”

“Not surprised. Appreciative.” She pushed on his shoulder, and sat up at the same time, until he was on his back, and she was leaning on top of him.

He squirmed, reveling in the way the soft comforter felt almost scratchy against his spanked skin.

She got on her knees, straddled him, and used a hand to help guide his cock in as she lowered herself onto it. She leaned forward and put her hands on the bed next to his shoulders as she started moving up and down slowly.

His hips moved in time with hers, while his hands ran down her sides and over her hips to caress her ass. He lifted his head off the bed to kiss her while they moved. After a few seconds, his hips started to move slightly out of time with hers, urging a faster pace. One of his hands went to her breast, while another went to cup her pussy, putting light pressure on her clit.

She broke off their kiss, and stopped moving her hips. “Are you trying to speed things up?” she asked with a teasing smile.

“Definitely.” He tried thrusting his cock in deeper, lifting his hips up off the bed in the process, which raised her entire body up a couple of inches.

She chuckled, and made a tisking noise. “None of that.” She sat up to free her hands, and captured both of his wrists in hers. She lifted his arms up over his head, crossed them at his wrists, and pressed them into the pillow. When she let go, he left his arms where she’d put them.

“I want you to keep your arms just like that as if they were cuffed,” she said.

A needy whine came out of his throat, his hands balled into fists in an effort to keep them still, and he thrust into her again.

She put her hands on the bed, and moved up and down. He started moving his hips faster than hers, and she froze in place. She leaned down to whisper in his ear, “Every time you go faster than me, I’m going to pause and count to ten.”

“Kate, please,” he said desperately.

“Mmm.” she hummed. “Be patient.” She started moving slowly again.

He forced himself to match her pace, even though it was excruciatingly slow. With his hands mentally restrained, the abraded skin on his ass rubbing against the comforter with each stroke, and Kate’s beautiful naked form riding him, there was no way he’d be able to last for very long.

She found the sight of him following her instructions deeply satisfying, and highly erotic, especially since it was obviously a strain for him. His submission pushed her to move faster. One of her hands went to her clit as she sped up the pace. Within moments she felt his cock pulse.

“Kate.” He groaned as he came.

Her body clenched in response, bringing her to climax.

They locked eyes for a second while their bodies were still entwined and pulsing with aftershocks. She broke eye contact first, and lay her head on his chest. She let her entire body go slack on top of him while she caught her breath.

He circled both his arms around her waist, and whispered, “That was amazing.”

She nodded in agreement. “Amazing.”

He ran his fingers up and down her back while they enjoyed the quiet together. Several minutes later, she reluctantly pushed her upper half off of him, and said, “I should go clean up.”

“You are going to stay the night, aren’t you?” He asked.

“If it’s okay with you.”

“If it’s okay? I insist.”

She grinned. “Then I guess I’ll stay.”

“Good.” He pointed to the left and said, “Bathroom’s that way.”

A few minutes later they were snuggled up in bed together, sleeping peacefully through the night.
