"So, you've got feelings for Castle. What's new?"

Kate narrowed her eyes at Lanie. "I don't want to get my heart broken when he finds some one better looking than me."

Lanie looked at Kate like she had two heads. "What's in your food to make you think such a thing would happen?" Kate opened her mouth to throw some smart ass retort back, but Lanie cut her off. "You are a beautiful, smart, kick ass woman Kate and you know it as well as I do. I don't understand why you doubt yourself when it comes to Castle."

"I'm just not used to such affection." She hedged.

"Please girl. You can't fool me." She pointed her half eaten bagel at Kate. "You're just scared of commitment and I'm not saying it's not valid, especially after Mr. FBI." Kate closed her eyes, remembering her issues with Will. "But I've seen how Castle looks at you honey. He has no plans on seeing anyone else but you." Kate stared at the empty plate in her lap.

"I know Ryan and I tease you Beckett, but Lanie is right." Esposito was standing on the other side of the coffee table, dressed for work. She gave him a small smile, which he returned. Giving Lanie a kiss goodbye, Esposito left.

"He's a good big brother." Kate sighed contentedly.

"Oh, he's a big something alright." Lanie mumbled into her coffee cup. Kate's hands flew to her ears.

"LANIE!!!!" Kate shook her head at her chuckling friend. "OVERSHARE!"

Kate stood outside of Castle's penthouse door. She'd been standing there for a good five minutes, debating with herself. Lanie was right. You've got nothing to worry about. Knock on that door and talk to him. She finally raised her hand and knocked lightly. She wasn't completely surprised when Alexis answered the door, a knowing smile on her face. "Hi Detective."

"Hey Alexis. Is your dad home?" Alexis nodded and turned, heading towards Rick's office. Kate shut the door behind herself and laid her jacket on the back of the nearby love seat. Alexis pushed the office door open and Kate entered. Rick sat in his desk chair, his hands folded across his chest, staring at the laptop screen. She heard the office door click shut behind her, but Castle didn't budge. "Castle?"

He startled at her voice, as if he hadn't heard a voice in days. She could see light return to his eyes as he gazed at her. "Kate." He said her name as though it was a life preserver and he was drowning.

"I've never seen this side of you before." She moved to lean against the desk.

"What side?" He tried to sound nonchalant as he adjusted himself in the chair. Kate gave him one of her trademark looks and he cleared his throat. "You scared me." Kate's brow furrowed in confusion. "Our night as going fine. We share one dance and you suddenly want nothing to do with me."

Kate shifted her gaze to the window overlooking the city. I scared Rick Castle. He wasn't lying, I can see the pain in his eyes. He really does care. "I'm sorry Rick."

"You came back though."

She finally looked back into his hazel blue eyes. "I was scared." Castle stayed quiet, knowing she was working out her words. "I'm used to being by myself and if you tell anyone else this, I'll shoot you, but I have commitment issues." He smiled at her mix of humor into the serious conversation. She moved to stand in front of him, closing his laptop and leaning back once more. "But I'm willing to give us a try." Castle was grinning from ear to ear. Why must he look so happy and goofy when I'm trying to be serious. But it's so darn cute. "You must promise me something though."

"Anything." He answered, suddenly serious.

"If I need space, even for just a moment, don't take it the wrong way. Sometimes I just need to be able to think without anyone else around. It's just how I work."

Rick leaned forward and took her hands in his. "I'll do anything for you, if it means you're willing to be with me." Kate smiled down at him and tugged at his hands to make him stand. He chuckled as he collided with her.

"I missed you." She purred, moving her hands to the back of his neck. She brought her lips to his, brushing them lightly over his. When she received a groan in response, she crashed her lips to his. His arms immediately went around her waist, holding her as close as possible.

"Oh god Kate." He moaned against her skin as he moved to place kisses along her jaw and down her throat. Her hands moved to tangle in his hair as his kisses left trails of fire on her skin. Oh the things he does to my body. I need more. I want more. NOW!

"I need you Rick." She whispered, nibbling on his earlobe. It seemed to have the right effect as a guttural moan escaped his throat and he picked her up, placing her firmly on the desk. Kate wanted less clothing between them and tugged at his shirt, trying to get it over his head. He chuckled and let go of her momentarily. She protested his absence until he removed his shirt and began working on his pants. Seizing the moment, Kate slid off the desk and quickly shed her clothes. Rick scooped her up again, plopping her back down on the desk as his mouth immediately latched onto an aroused nipple. She cried out, her hands tangling in his hair once more. Oh sweet Jesus that feels good. My body feels like it's on fire. Oh god! He moved on to the other nipple, giving it the same lavish treatment. She finally pulled his head away when she thought she was going to loose her mind. He gave her a quizzical look and she could only smirk. She brought a delicate foot up to his chest and pushed him back into his chair. He looked more alarmed now, memories of the Halloween party coming back to him.

"No handcuffs?" He asked, trying make light of it.

She bit her lip, earning a gasp from him at the sight. She slid off the desk and bent over to kiss him, her hand falling to his lap. She gently began to stroke his cock, causing his breath to hitch. She placed kisses down his jaw, to his neck where she nibbled gently. He grunted and his hips thrust up in response. She chuckled and let go of him, his eyes snapping open and locking with hers. She turned her back to him and Rick began to wonder if she was going to leave. His thought process became mute when she slowly sank back onto his waiting erection. They both groaned deeply, having missed the feeling of being connected like this. "Ooohhhhhhhh." Was all Kate could manage for a response. She steadied her hands on the arms of the chair as she felt Rick's hands move to her hips, gripping them gently. He tried to move her, but she remained still.

"Kate." He pleaded, but she only threw a sexy grin over her shoulder at him. She waited till he stopped trying to move her and then squeezed her inner muscles. A low growl from behind her told her it was having the right effect. Rick's hands moved to pull her against his back as her muscles continued to clench around him. "You're torturing me." He breathed, kissing just below her ear. Kate bucked on top of him, her body unable to resist the electricity that coursed through her. His hands moved to her breasts, kneading them gently as she began to move on top of him slowly.

"Rick." She moaned, her movements becoming erratic, her breathing heavy. Rick could tell she was close and slid a hand between her legs, stroking her clit gently. "Oh god……oh……" He held her as she arched and shuddered, before slumping back against him. She purred contentedly, a hand reaching behind her head to tangle in his hair. "I knew you were good for something." She chuckled.

Rick kissed and nibbled her shoulder, thrusting up into her. We're far from done Kate. He wrapped an arm around her waist and put one hand on the arm of the chair, then pushed up. She gave a surprised squeal as he bent her over the desk, admiring the view of her beneath him. She threw him a sultry glance, biting her lip. Rick couldn't take anymore. His hands steadied her hips, readying her for the storm. He pulled out agonizingly slow, causing Kate to groan. He then slid back in at an excruciatingly slow pace. Realizing she'd have to take matters into her own hands, Kate placed her hands firmly on the desk and shoved back. Rick growled down at her and she chuckled evilly. Rick pulled back to slam into her, his body aching for release. "Richard?" Kate and Castle froze at the sound of Martha's voice. Kate threw a nervous glance at Rick, who was clearing his throat.

"What is it mother?" He croaked.

"Are you alright?" She sounded concerned. Kate chuckled to herself, Alexis must not have told Martha that she'd come by. Knowing she would pay for it, Kate decided to have some fun. Castle opened his mouth to reply and Kate shoved back onto him once more, making his body tense and shudder as he tried to control himself.

"Fine." He groaned deeply.

"What?" Martha asked, sounding a little agitated. "What are you doing in there Richard?" Rick glared down at Kate, pleading with her to be still. I don't think so Rick. I'm having way to much fun. Rick opened his mouth to reply once more, but Kate clenched her walls around him once more. His eyes closed and he bit his lip to keep from moaning loudly. Wow, I didn't know how sexy it looks when Ricky bites his lip like that.

It took him a moment to respond, but he finally uttered a normal response. "I'm working mother. I'll be out in a bit." Martha seemed to accept his answer, because they could hear her receding steps. Kate could feel him staring and she looked over her shoulder at him innocently. "You're going to pay for that." His eyes glinted with mischief. Kate's sassy retort stuck in her throat as Rick slammed into her over and over, never relenting. Kate tried her hardest to swallow the scream of pleasure that was threatening to escape her. She resorted to biting her lip hard, not caring if she bled as another powerful orgasm ripped through her core. Feeling her release around him, Castle let out an animalistic growl and exploded in his own orgasm.

They both lay catching their breath, bodies sticking together with sweat. "Oh, you are amazing." Kate breathed as he moved off of her.

"Can I get that in writing?" Castle chuckled as he dodged a hit from Kate. She quickly dressed, smoothing out the wrinkles in her shirt. She moved to the door, cracked it open and peered out. "Who are you looking for?" Kate looked back to see Rick tucking his shirt in.

"You're mother Castle. If she sees me, she'll know you were doing more than working."

Castle couldn't help but laugh. "I doubt it's a secret." Kate raised a brow curiously. "No, I didn't tell her, but she's smart enough to have figured it out on her own." Kate pondered this and shrugged, knowing he was right.

"Fine." She strolled back to him and kissed him softly. "What are your plans tonight?"

Castle shrugged. "Now that I know you're not ignoring me," Kate fixed him with a sharp gaze and stuck his tongue out, "I was just going to relax at home. Did you have something in mind?"

"How about a movie night?" She replied, moving back to the office door and opening it.

"Sounds good."

"Good, I've got to stop by the office to check on a case and then I'll be by tonight." Castle smiled and walked her to the front door, his hand on the small of her back.

"I'll see you tonight then Kate." He gave her a quick kiss and as Kate turned to leave, she saw Martha entering the living room.

"See you tonight," she replied sweetly, "and thanks for the writing lesson Castle." She emphasized loudly, knowing Martha would hear. She chuckled as she headed down the hall toward the elevators, knowing Castle was staring after her in embarrassment.
