Sorry this took so long in getting updated. Life is so getting in the way, and I just don't have the time to write as often as I want. I am not giving it up, and I hope you guys continue to read. Please leave me a review; I could really use the encouragement with everything going on. Hope it is worth the wait.

Disclaimer – If they were mine, Castle and Beckett would be naked at least 50% of the time. As you can see, they are not on HBO or are they even making cute Castle babies!

Chapter 4

In one smooth move she flips them so he is lying below her. She grinds her wet center the length of him and watches him close is eyes and make the most delicious sounds to her ears. She runs her fingers up and down his sculpted chest enjoying how his skin responds to her touch.

The sexy detective lifts her body and takes him in her hand, pumping him hard a few times. She places him at her wet entrance and watches as they both wait in anticipation. She bites her bottom lips as the tip of him just enters her. Her legs quiver in anticipation and she closes her eyes for a second enjoying the feelings flooding her body.

She opens her eyes to meet his in a searing lustful glare, which send chills down her spine. She lets her legs go limp, and sheaths him in one motion deep inside her. Her head snaps back as the most primal sensual sound Castle has ever heard escape her lips. Her body arches over him and she reaches up and touches both of her breasts. His eyes rivet themselves to the way her fingers start working her taut nipples. She grinds down on him, causing waves of pleasure to ripple throughout every inch of his body. He watches as her head moves again and her eyes, dark with a feral passion watch him like a lioness stalks her prey. She bites her bottom lip as she lifts herself and again proceeds to impale herself with him. Every inch of her is filled to the brim; she can hardly control the animalistic passion coursing through her body.

"Castle." His name escapes her lips in a half whisper, half moan. She lifts her body away from him again, and he takes the opportunity to move them back against the headboard giving him better access to her body. Their bodies fuse together as his lips explore the crease of her neck where her pulse point is. His hands join hers at her breast mimicking her motions.

"Mmmm," she moans.

"You feel incredible, Kate." She feels his breath on her neck; his voice low and sexy, vibrates next to her ear. "You were right, I really had no idea."

She lets herself come down off her knees again and a gasp escapes her as she feels him hit even deeper in her. Her pace quickens and they find their rhythm. Her breasts glide over his chest. She watches his eyes darken further and feel his hands glide over her body. One hand finds her ass and kneads it, guiding her body over him. His fingers dig into her flesh, and she knows they will leave a mark, but can't seem to care. The other hand snakes between them and slips between her wet folds. He finds her clit and pinches it between his thumb and forefinger. She moans loudly and her breath now comes in short gasps. She is losing control of her body and her thrusts become erratic. She has never wanted to cum so badly in her life, every inch of her is burning with desire for him.

Castle flips her over, throwing her onto her back. Her hair splays around her head, and for an instant he contemplates how absolutely gorgeous she is. He shakes his head bring him back to the moment. He thrusts into her in abandonment, losing all semblance of control. He growls over her; his eyes dark with lust and love.

"God, what you do to me woman." He growls at her. "I have never wanted someone this much." His body slams into her, and he pulls her legs up high around his hips to get a better angle.

She tries to tell him that she is close but her lips aren't cooperating, she can hardly think of anything but his cock slamming into her, and making her feel incredible. All she can think of is their release, and how much she needs it right now.

"Please Castle, God, I need it, please," her voice is needy and desperate. She snakes her hands around his neck to his hair, grabs it and pulls him roughly to her lips. She sucks his bottom lip and bites it as her orgasm starts to overtake her. She shatters intensely around him. Her body shakes involuntarily, and her nails dig into his shoulders as his name tumbles from her lips.

He continues pounds into her with abandonment. His name spilling from her lips, and nails digging into his shoulders as her walls constrict around him, cause him to finally find his powerful release. He empties himself into her as his arms give out and he collapses limply on her.

He rolls off her and instantly gathers her to his chest. Their bodies melt together as she gets lost in his eyes again. She absently plays with his ear, her touch gentle and causing him chills where her fingers trail. Castle kisses the top of her head before nuzzling his face into her hair and taking in the scent of her. A satisfied smile slowly spreads across his face as he wraps his arms around her.

"I love you, Katherine Beckett." Castle says lovingly into her head. His heart is full and he knows he is never letting go; this woman is "it" for him. She completes him, and he can't live without her anymore.

"I love you, Castle." She whispers back as her hands wrap around his neck to keep him close to her. She knows that things won't always be easy, but she knows she will never have to fight anything alone again. Her walls have crumbled and she won't ever have to ask "if only?"

They will have tomorrow and the rest of their lives to figure it out.

This is it, the end of this story. Before them is life and their happily ever after. I can't have it any other way; these two have to make it. I hope you enjoyed the story. If you do please let me know! Thanks again for reading.
