I had planned on this being a one-shot story, but some people requested that I write a second chapter, so, here it is. This second chapter is a little dirtier than the first, not super bad (there is a steamy shower scene) - but the language is less romantic and a little more dirty (definitely M rated language in this chapter) - so, if you don't like that, you may want to skip this part of the story.

I definitely appreciate any feedback or constructive criticism. If you leave a guest review, please know that I very much appreciate your feedback - it's hard not to be able to thank the people behind the guest reviews because you guys are often extremely helpful. I hope you enjoy!

Castle wakes to the sunlight streaming in through the window. He curses himself for forgetting to close the curtains tight last night. Although, he was a little distracted with certain events that took place. He smiles as the memory of the night before rolls back to him. To his delight, Kate is still snuggly wrapped in his arms, so he takes a moment to enjoy the warmth of her body next to him. She's peaceful and gorgeous in her sleep.

He slowly turns towards the nightstand to see that it's 8:37am. He knows that she still has some investigating to do today, but considering they didn't make it to bed until after 2:00am, he wants to let her sleep, just a little while longer. He rolls back over towards her, careful not to disturb her. Snuggling up to her, he puts his nose into her hair and breathes in her scent. She smells divine, she smells like his. He begins to drift back to sleep again when he feels her stir next to him. His grip tightens when she tries to pull away from him.

"Castle, I'm sorry, but nature calls, I really need to go to the bathroom" she tells him with regret in her voice.

He groans. "Ugh, ok, but don't take too long love."

"Castle, it's almost 9am. I need to finish up my investigation here today, and my flight leaves at 7:00 tonight" she reminds him.

"Does that mean you aren't coming back to bed this morning?" he asks her.

"Unfortunately, yes, that's what it means. I need to get ready, and head out to interview a couple more people who could help me crack this case. I'm going to take a shower; care to join me?" she stands up and seductively slides across the room to the bathroom door swaying her hips provocatively. When she's at the door, she places her hand on the frame and looks back at him with a devious grin before disappearing into the bathroom.

Castle can't move fast enough. He jumps up off the bed, nearly tripping as he becomes tangled in the bed sheets. When he makes it to the bathroom door, he catches her naked form slipping into the shower. He's not quite sure how clean they are going to get this morning, since he feels more aroused now than he was last night. How can that be possible?

He walks slowly over to the shower and opens the door. He slides in behind her and wraps his arms around her waist. The water beats down on his back, soothing his sore muscles from last night's love making.

"Mmmm, what took you so long lover?" she teases him.

"I almost killed myself on the bed sheets getting in here, sorry to make you wait" he kids.

She turns towards him, and looks up at him through her lashes. She bites her bottom lip and runs her fingers over his chest and his shoulders.

He runs his hands up her sides and down her back, water streaming through his fingers as he stops on her ass and pulls her towards him.

"Mmm, someone is happy to see me this morning," she smiles as she backs her hips away from him, allowing her to get her hands around his erection.

Castle sucks in air through his teeth at the feel of her hands on his cock. "Oh god Kate, the way you touch me, it's exquisite."

With one of her hands she grabs the bottle of body wash and pours a few drops onto his length. She continues stroking him, up and down, lather building, her hands sliding easily along his shaft. He closes his eyes tightly, and begins breathing heavy. He lightly bites her collarbone and licks the water off of her shoulder. He brings his hands up to her breasts and begins massaging them. His mouth finds hers as they kiss passionately under the water.

Kate lets the water run down on his length, rinsing off the soap she just lathered on him. She slowly sinks down to her knees and takes him into her mouth.

Castle trembles, "oh...my...god, Kate, holy...damn woman that feels so good" he stutters.

She circles his tip with her tongue and then opens her mouth to take him in as far as she can. Her fingertips gently graze his balls as she tastes every inch of him.

"Beckett, you need to stop, I can't...I'm going to," he tugs at her hair to coerce her to stand back up.

She releases him from her mouth, stands back up and looks into his eyes. She smiles shyly at him before kissing him chastely.

"Mmm, I hope you'll let me finish that sometime, I would like to taste every bit of you Castle, every single bit" she seductively tells him as she kisses his jaw.

"Someday Kate, but not today. Today I need to be inside of you, I need to feel you shatter around me."

"Mmm that sounds nice Castle, I want that too." She begins stroking his length again, running her fingernails along his scrotum and kissing down his chest.

Her touch makes him lose control. He can't play like this anymore. It's as if the animal inside is woken up. He pushes her up against the tiled wall, his mouth finding hers.

"Ah" she gasps as she breaks their kiss, "Castle...wall...cold" she stammers, pushing him back just a bit to get her skin off of the wall.

"Sorry Kate, I just can't get enough of you, I want you, I'm never going to stop wanting you" he looks at her hungrily.

He turns the shower head so that it begins streaming water down the wall and her back.

Slowly his lips find hers, he nibbles her bottom lip and she opens her mouth to him. Their tongues dual for dominance. This is much more heated than last night, they are hungry for each other. He places one hand on the back of her thigh and lifts her leg. She curls it around his waist and his hands begin wandering down to find her wet and tight. He gently runs his thumb over her swollen clit, and slides a finger inside her.

She moans, "Castle, we are never going to get out of here if you keep doing these naughty things to me."

With that, he moves both of his hands to her hips and lifts her up as he pushes her against the wall again. She wraps both of her legs around his waist and can feel his erection at her entrance. He won't let her sink down just yet, and he continues to hold her up without pushing himself inside of her.

"Tell me what you want, Kate." he tells her, closing his eyes as his forehead rests against hers. His breathing ragged and shallow.

"Make love to me Castle" she whispers, placing her forehead against his as she closes her eyes.

He opens his eyes and pulls back to look at her. "I don't think that's what you want Beckett. I don't think you're being honest with me." he stares at her with a lust filled intensity.

She understands what he's doing, what he wants from her, and she likes it. She is incredibly turned on now with this little game he's playing. "Rick, I want you to fuck me. Fuck me against the wall until I can't walk. Show me that you really want me. Make me believe it." she breathes.

He smiles, knowing that she's ok with playing a little dirty this morning. He looks at her, she's beautiful, her hair is wet and hanging limply by her perfect skin. Her cheeks are flushed with her desire for him; her hazel eyes are dark and filled with lust. He waits, making her whimper.

Beckett decides to take the heat up a notch and gets feisty with him, she can see that it's turning him on. "C'mon Castle, what are you waiting for? I need you deep inside of me. I need you to pound me senseless. Do you want me or not?" she teases him with a serious tone to her voice.

His mouth drops open, and without any words, he pulls her hips down hard and impales her. They both loudly groan as their bodies join together. Kate leans forward and kisses him hungrily. Their lips moving together, fast and furious, tongues circling as they work themselves into a frenzy of tangled arms and legs while Castle pounds her up against the shower wall.

Trying to keep his balance, he places the palm of one of his hands on the wall. He breaks their kiss to get some air and lays his head on her shoulder panting.

"Kate you feel so good, you are so wet. God, I'm close." he grunts.

"Oh my god Rick, it's so deep, so deep, I'm there, I'm, oh god, I'm cumming," she screams as she shatters around him. She lays her head back against the tiled wall; her walls tighten and her breathing is heavy and shallow.

Castle can't hold back anymore, as soon as he feels her walls clench around him, he loses all control. He speeds up his trusts and empties himself into her, plunging as deep as he can to feel every sensation. He groans loudly as he rides out the last of his climax.

"Oh god Kate, you're a naughty girl, I like it" he says with a grin.

"I've never done that before Castle, that was fun." she says, as he lowers her down and gently slides out of her.

"You've never done what? Shower sex? Or dirty talk?", he looks at her inquisitively.

"Well, neither I guess." she says, shyly as she looks away from him.

"Hey, no need to be bashful. My god Kate, you're amazing, at both...at everything. I've never felt anything this intense before, physically or emotionally. You have nothing to be shy about." he tells her, lifting her chin with his fingers.

"I can't believe we just took this to the next level last night. It feels like we've been doing this forever. You know my body and my desires so well." she says as she embraces him.

"Well, it's not like we just met Kate, I know you, I've loved you for a long time now, and I've paid attention" he says, winking at her.

"Clearly Castle, I've never wanted anyone the way I want you. I'm having a hard time keeping my hands off of you." she says with a giggle.

"Well, I am ruggedly handsome" he begins peppering her with light kisses.

"So I guess that having a hot," kiss to the temple,

"sexy," kiss to the jaw,

"amazing," kiss to the neck,

"extraordinary," kiss on her lips,

"woman who cannot keep her hands off me is just part of the gig." he broods.

She smacks him on the chest, and kisses his lips. "I think it's time to get going, there's still work to do today" she tells him, smiling, but disappointed that she can't continue with their shower escapade.

"Well, you have been quite dirty this morning, so let me help you clean yourself up a little." Castle jokes with her.

He takes the shampoo and lathers her hair. Her hands find his in her locks and together they massage her scalp. She leans her back up against his chest, and her head against his shoulder. She feels his arousal coming to life again against her skin.

"Castle, we can't; we really do need to go, so you need to put that thing away for now." she tells him as she turns to meet his eyes.

"I know Kate, I'm trying, I'm not doing it on purpose. I just can't help what happens to me when I'm around you. Before this...us...together, I could just hide it behind my jacket, or a bag, but you've always done this to me. Now I get to touch you, feel your skin against mine, it's next to impossible not to have this reaction." he confessed.

"Here, let me wash your back Castle" she blushed. "I love that you have this reaction to me. It's incredibly hot, and I want this, I'm never going to get enough of you now either, but let's save some of it for later, when we get home to New York, ok? I have something planned for you, and you won't be disappointed." she teases him seductively.

"Oh really Detective Beckett, would you care to give me any hints for what my evening holds?" he asks her, wiggling his eyebrows at her.

"Let's just say we'll be needing my handcuffs, some whipped cream, and your dining room table for starters." she turns her back to him, not waiting to see his mouth drop open in surprise.

"My god woman, you were right, I had no idea!" he tells her, taking a breath, not realizing he'd been holding it.

They finish washing each other slowly with the loofah, taking extra time to linger on each other's sensitive parts. They kiss passionately, tongues mingling, and then embrace as the water streams over them. Finally Castle reaches back to turn the water off. He opens the shower door and grabs Beckett a towel. He grabs one for himself and they slowly dry each other off, their eyes never leaving each others.

"Thanks Castle, that was nice." she said, looking at him shyly.

"No, thank you Kate. You're amazing, and I have a feeling you're going to continue amazing me in the days to come. I can't wait." he said, kissing her gently on her forehead.

Beckett smiles at him and then turns to walk out of the bathroom. She makes her way back across the suite to get her clothes from her room. As Castle finishes dressing, he heads across the suite to find out where they are headed today. Kate doesn't hear him approach, so Castle stands in the doorway watching her dress and thinks about how much his life has changed in less than a day. He is amazed by the strength she has shown in the last 12 hours.

She catches him watching her, "Hey there stalker, can I help you with something?" she jokes.

"Kate, I just want you to know that you can trust me, with everything. Our secret is safe for as long as you want and need it to be. I will always be here when you need me Kate, always" he explains to her with complete sincerity.

"I know Castle, I'm sure about this. It's taken me a long time, too long, but I'm sure, and I want this." she crosses the room to embrace him.

She gives him a gentle kiss on the nose and walks back over to her bed to put on her shirt.

He leaves her to finish getting dressed. As he sits on the couch in the suite lobby, he smiles as he thinks about what has transpired with Beckett over the course of the last day. He can't wait to head home and explore more of their relationship, and discover each other in a whole new way.

Kate puts on her make-up and blow dries her hair. She finally has something positive to focus on and be grateful for in her life. Navigating the complexities of this new development in her relationship with Castle might be tricky, but she's looking forward to sharing her life with him. She feels relieved to know that she can share the sorrow, the burden, and the joy that is sure to come in the days, and hopefully, years ahead.
