Chapter 1

Kate sat at home, in the arms of Josh the night after she and Castle kissed. She felt weird. Of course, who wouldn't when you just kissed a guy who's not your boyfriend and then just went on acting like it was 'just' an undercover kiss. No. It wasn't just an undercover kiss. She felt… blown away by his lips, hands… taste.

But yet, she still sat in Josh's arms, not able to hurt her boyfriend by telling him, or even breaking up with him. It was meaningless, she told herself. She believed she had never told herself a bigger lie.

She was pulled out of her thoughts by Josh's phone that went off. He answered it as she silenced the TV.

"Yeah, okay. I get it." Josh said as he sighed.

Kate knew he was needed somewhere, but where? He had just come back… for her.

"Who was it?" she asked him.

"I'm so sorry Kate, I know I came back for you, but I'm still on call in the hospital. It's only until I'm off call, which is tomorrow evening. I'll call you, okay?" he stood up, as she stayed in her place on the couch. He bent back down to peck her lips.

"I got a few days off, so you know where I'll be." Kate sighed. She didn't like days off, but she agreed with her Captain. She understood his point of view.

As Josh walked out the door, Kate turned the TV back on. She was kind of glad he was gone, but she also wanted him here to make her thoughts about Castle disappear. She didn't want to be thinking about his lips. How they felt on hers. His tongue, soft and loving. His hands, roaming over her body.

And his hands in her hair. It felt even better than the first time their lips touched. The way he pushed himself into her, and pulled her towards him, it was heavenly. Even just remembering it got her flushed. Her body heat was rising, a craving feeling came up inside of her.

Suddenly, thoughts of what could be popped into her head. Thoughts of her and Castle, tangled between sheets, lying so close to each other you wouldn't be able to tell the difference between their limbs. Soft sweet kisses. And then the heat rising again within them. Her hand, trailing down his chest, his abs underneath her fingertips. She felt him shivering. "Oh god Kate" she heard him say as her mouth marked his neck.

She was pulled out of her thoughts, again, by a ringtone. The ringtone she put for Castle. Hesitantly, she grabbed the phone off the table next to her, and checked her inbox.

'Hey Kate, I know we haven't talked about it, but I can't forget about our kiss. I'm sorry, but I can't just drop the subject.'

Kate was hesitant, should she tell him she couldn't forget about it either? Or should she lie, that was the better option. No one would get hurt that way… but she couldn't. It didn't feel right.

'I can't either Rick… I keep thinking about it.'

Within second she got a reply. 'I'm glad to know I'm not alone. I keep imagining your lips on mine… Tell me it wasn't just me who loved that feeling…'

Kate bit her lip. This was wrong… so wrong… but she couldn't stop herself.

'You're not the only one. But I can't… I can't keep imagining you. Your hands… lips. I can't. It's not right. But I can't stop it.'

'Oh Kate, It's the same with me. My hands in your hair… I can't forget how wonderful it felt.'

Kate saw it happening again in front of her eyes. It got her so worked up.

'Castle, please… I can't do this to Josh…'

'Forget about Josh, he doesn't matter now. Just think about me. Running my hand up your leg, going higher and higher. My lips, trailing down your totally naked body. Such a hot body.'

Kate couldn't handle this. She didn't reply. She just walked to her bedroom, getting ready for the night.

Soon she got another text though.

'Your folds, so wet for me. My thick fingers pleasuring you as my mouth trails down, to you breasts'

Kate shouldn't have read it. She shouldn't have. She couldn't help but lie on her bed, in underwear, her one hand clutching the phone, her other trailing down her body. She shouldn't be doing this, but it was too much. And it wasn't like she was doing anything wrong. She wasn't cheating on Josh. But she was imagining Castle there instead of him. And that was not right. But no matter how bad she wanted it, she couldn't change it.

'Can you feel it, sexy? Can you feel my big fingers sliding into you? My tongue trailing down your body, to your bellybutton.'

This was becoming too much for her. She bit her lip, trying not to make any noises, as her fingers reached her wet folds. She kicked away the sheets, as they became too hot on her sweating body.

She could barely open her eyes as the next text came.

'Open the door Kate.'

He was there! No… oh no, the door was unlocked… she forgot to lock it! Shit… Now he was going to come in…

And sure enough, a few seconds later she got a text saying he was coming in. She moaned a 'no' but her body screamed yes. She couldn't stand up. Not now. She was too close to it. She couldn't stop moving her fingers. She threw her head back as she heard footsteps on the floor.

"Kate… Oh sexy where are you?" she heard him say. The footsteps came closer and closer. She didn't stop. She didn't want to stop.

"Oh fuck!" Rick groaned as he walked into her bedroom, door wide open, Kate lying on the bed, pleasuring herself.

Kate's other hand, that was clutching the phone, let go and she cupped her breast, as she pushed herself off of the bed, on her head and feet.

"Oh so sexy" she heard Rick say as he moved towards her.

"Castle… Rick!" she moaned as her fingers pushed in herself again. It wasn't enough. She was close, but she'd never manage herself.

Rick had already taken off his shoes and coat as he entered her apartment, he was only wearing a shirt, pants and of course boxers underneath. Boxers that were starting to feel too tight.

"Help, please" she groaned as she reached for Castle.

She felt cold hands trailing up her leg. Coming dangerously close to her wet folds. His hand touched hers, and he pulled it out. She felt her fingers touch another sort of wetness. His lips, and soon his tongue. She could feel him sucking on her fingers and it felt so good.

"My god Kate." Rick breathed as he climbed the bed, closer to her.

She was laying on her back, her left hand on her breast, the other above her head. Rick's hand was hovering over her folds, he was laying on his side, supporting himself with his right, and waiting for her with his left.

"Come on Rick, don't make me lose my heat. Please." She said, barely louder than a whisper, and she didn't have to say it twice. Rick traced his fingertip over her wet folds, to her clit and started circling it. Kate whimpered as she grabbed the sheets.

"Rick, please, more." Kate managed to get out. And Rick let his fingers trail down to her entrance. His thumb still making circles. He was watching her as she bit her lip, craving more.

"You look so hot Kate." he said and planted a kiss on her shoulder. He pushed himself up with his other hand, sitting himself up a bit more with his knees and hand, as he leaned down to kiss her neck. He was hovering over her, still not allowing her the pleasure she wanted.

He was marking her, and she honestly didn't care. It felt too good.

"Rick… please." She hummed as one hand grabbed the back of his neck, and she bucked her hips against his hand. "Please help me."

Castle figured she had begged enough. She wanted him, that much was clear. His boxers were becoming too tight and if he waited longer, it would really start to hurt.

He trailed kisses up to her lips, and as his lips made contact with hers, he stopped his hand motions. He was too taken away by her soft lips on his. She bucked her hips into his hand once more and as their tongues touched, he pushed two fingers inside of her.

She gasped as she pulled herself up with her hand that was circled around his neck. His fingers were magical, it felt so good. Perfect.

For him it was the same, her walls around his fingers made him even harder. He slowly moved his fingers out of her and he started kissing her again. He pushed into her again, and again and she was amazed every time. And when she was adjusted to his fingers, he put in a third finger which made her lose control. Her hand on his neck lost her power and her back hit the bed again.

She bit her lip again, it felt like nothing before. Never had it been this good.

"Rick, I want you." She moaned.

"You already have me Kate."

"Not what I meant." She moaned as she bucked her hips once again. She tugged his shirt and pulled it up. He pulled his fingers out of her heat so take his shirt of as she started to unbutton his jeans.

He didn't waste time kicking them off. He noticed Kate's hands had stopped moving.

"Kate, what's wrong? Do you want to stop?" Rick asked in concern. He met her eyes when she looked up from her hands.

"Nuh-uh, no, not at all. It's just- "

"What Kate?" Kate swallowed, and took a breath.

"You're so big." She moaned as her hand grabbed him.

Rick moaned from the unexpected pleasure. "Don't worry babe, I'll be gentle. But I can't promise it won't hurt."

Kate just gasped as rick bucked his hips against hers. He was bigger than she thought and she knew he would hurt her. But she didn't care.

"Now Rick, please." She begged him as she put her fingers around the waistband of his boxers. His bowers that were way too small by now.

The room was lit by the bedside lamp Kate had, so when his boxers were off, she could see exactly how big he was.

"Oh god…" she said as she stared at his manhood.

"Nuh-uh Kate, not god. Little Rick." Rick said as he leaned down to kiss her neck again. His hips bucked against her hand, and she pumped him.

"Not so little. And I prefer another name." Kate smiled as she enjoyed the feel of his arousal in her hand.

"What do you want to call it?" he asked in between butterfly kisses. "Not dick right? Too lousy." He groaned as she pumped him again and kneaded his balls.

"No," she chuckled as she felt his tip brush against her wet pussy. She pulled his head close to her mouth, and whispered. "I like cock."

Rick groaned as Kate bit his earlobe. It was becoming too much for him. As his cock grazed between her folds again, she gasped.

"Rick…" she gasped again as his tip stayed at her entrance and they stopped moving.

"Yeah?" he asked, meeting her eyes again.

"I- I love you." She smiled.

He looked into her eyes a moment longer and leaned down to kiss her. As their kiss deepened, he moved his hips and slowly entered her. She gasped at the feel of him spreading her wide open.

She let out a loud 'oh' as he completely entered. He himself felt the effect of her tight walls on his arms. He could barely keep himself up.

"Damn Kate." he said as he regained his strength in his arms. He pulled himself up a bit, taking his weight off of her, and pulled out just as slow as he entered her. She whimpered and pulled him down again.

He felt amazing, and she didn't ever want to leave the moment. He had been right though, it hurt. But she didn't care. It was a good kind of hurt. As she was thinking about it, he entered her faster than before. Let it linger for a moment, and pulled out again. His thrusts became stronger and stronger as she felt herself come closer to her climax.

"Rick, make me scream." She groaned in between thrusts.

"Gladly." He grinned as he picked up pace.

A few heavy thrusts later, he was so close. "Come with me Kate." he whispered in her ear and kissed her neck. Her heartbeat fast underneath his lips.

She felt like heaven, her hips met his with every thrust. And his words sounded like an angel's voice. She was happy to obey him.

She hooked her legs around him and pushed him in even further and faster.

Her inner muscles flexed one more time around him before she screamed his name as her orgasm hit her out of the blue.

Her walls tightening around him were it for him and he pushed in one more time before he lost it all. He spilled inside of her but rode her orgasm out as she gasped. He collapsed on top of her, and turned them over, still connected to each other. He didn't want to let the feeling go.

"That was…" he groaned heavily.

"Best. Ever." She smiled between heavy breaths.

"Kate?" she hummed in response as she made herself comfy on his chest. She had the orgasm of her life, and her legs felt like pure jelly.

"I love you too." She smiled as he kissed her hair and put a protective arm around her. With the other hand he found the sheets and pulled them up a bit, over the both of them.

She hummed in response. "I'm glad. Now shh, I want to be ready for a round 2 when I wake up."

He chuckled in response, and stared at the ceiling.

Why the hell did we wait so long?
