Pulling her into his bedroom. They smile softly at one another. Then Rick comes up behind her and runs his hands down her back, his hand finding her zipper as he slowly undoes her dress, gently removing the shoulder straps, placing a kiss on each shoulder as he does so before letting it fall to the floor. Kate hears him gasp and she knows that her body still has his approval. He slowly turns her around and kisses her mouth, lightly stroking her hair. Then he kisses her neck down to her shoulder, in between her breasts, and down to her stomach.

The baby rests just below the thin skin of her stomach. Rick rests his head there for a brief moment. Kate can only wonder what thoughts are going on in his brain. The feel of his mouth on her body is unlike anything she has ever felt before.

Finally, he makes his way back up to her mouth. He kisses her harder this time and their tongues duel for control.

Kate runs her hands down his the bottom of his shirt and then she lifts it up and over his head. He laughs at her and whispers, "You could have undone the buttons instead."

She whispers, "Too many buttons."

"Impatient much?"

She gives him a look and it makes him smile. She takes a step back to look at his body. He has an amazing body. She has fantasized about touching him for a long time. Reaching out, she touches his chest. Taking time to circle each nipple. He gasps softly and she smiles shyly.

They walk to his bed and he presses her up against the foot of the bed. Not allowing her to fall onto it. Rick caresses her throat and presses himself against her body from behind. They both moan softly. She can feel how hard he is. She wiggles her bottom and he whispers, "Easy babe."

She moans softly and tells him, "I need you Rick.. So much..."

His hand slips around her body and up to her breasts, teasing her tender nipples through the lace cups of her bra, she moans loudly as the lace causes delicious friction against her skin. Kate pushes back into him, feeling his hard bulge through his jeans. Kate smiles and she rubs her bottom against him and she hears him moan softly as she feels him growing harder with every second.

Then Kate reaches behind her and cups his erection slowly gliding her hand over his crotch and she teases him as he groans with pleasure. He manages to croak out, "Fuck Kate."

She unbuttons his jeans and finally releases him from the confines of his pants. She curls her fingers around his length feeling him shudder with delight. She whispers softly, "I love how hard you are for me Rick. I've imagined this for . I love you. So, so much."

He moans against her neck and whispers, "Fuck Kate. Your hand feels amazing."

Kate smiles and bites her bottom lip. Then she hears his pants fall to the floor. She laughs as he kicks them to the side. His boxers soon hit the floor and he kicks them clear of their bodies. He presses himself against her bottom again so she can feel his cock between her thighs. His hands go around to feel her breasts once again cupping one in each hand. He slides them around her back and unhooks her bra letting the black lace garment drop to the floor.

He takes one of her breasts in each of his hands and softly fondles them, taking their weight and holding them firmly. Castle asked her softly, "Are they getting bigger?"

She let her head rest on the front of his shoulder and whispered, "I think so. I needed to buy some new bras today and. Ohhhh…" She moans softly as he pinches her nipples softly. Her legs threaten to give out on her. His hands are melting into her. It feels so good. Even if she wanted to, she's powerless to stop him. She is his. He rolls her nipples in his expert fingers and her skin feels like it is on fire..

He releases his hold on her breasts and lightly rubs her shoulders; tenderly he works his fingers into her flesh. A moan breaks free from her lips and Kate can feel something stirring in her stomach, that familiar feeling of overwhelming joy trying to break free. She has wanted this for longer than she can remember. Wanted to feel the love of his touch on her body.

She whispers softly to him, "Oh Rick…I'm going to...Oh….God...I'm…."

He whispers in her ear, "Come for me baby…"

Castle wraps his arms around her waist, holding her lovingly through her pleasure, his hard cock still between her thighs feeling her panties soak up her juices.

She whispers to him, "That's never happened before."

"What?"

"I've never come before from a man simply touching my breasts. God, that was amazing Rick.."

With his hands firmly holding her hips he keeps her pressed against the foot of the bed. Trailing kisses down her spine. She whispers, "I need to lay down on the bed."

He shakes his head and whispers, "Not yet sweetheart."

He kneels down and slips his hands up and down her legs enjoying how smooth her skin feels.

His fingers move up along the inside of her thigh and brush lightly against her lace covered opening. He murmurs with delight when he feels how wet she is. His fingers tease and taunt her through the wet lace and she moans and trembles unsure how long her legs will hold her.

Turning her around to face him he hooks his fingers into the waistband of her panties and eases it over her hips and down her thighs, his fingers trace her skin and she moans in anticipation.

Her panties are now on the floor with the rest of the clothes she wore that night. As he licks his way up her inner thigh, his tongue finds her clit as he licks and sucks her hungrily, the sensation is incredible and her knees begin to tremble. His tongue works up and down her wet lips and then slips inside.

She can feel her orgasm building as he alternates from tonguing her to sucking her clit. She can't stand it any longer and her orgasm overtakes her body and she cries out loudly, but he doesn't stop, he keeps up his tongue gymnastics feverishly working her over and her body convulses in multiple orgasms, again and again she loses control of her body and he holds her up in his strong arms. Finally her body can take no more and he returns to her mouth kissing me through the last of her pleasure.

Gently he pushes her down to kneel in front of him. She knows what he wants and she can feel her heart beating faster at the thought of it. She places light and teasing kisses on the his tip.. She runs her tongue around the head and he moans cupping the back of her head to urge her ever closer. Slowly she sucks on his balls knowing the delay is almost too much for him to take. she sucks them into her mouth and runs her tongue around them all the time still stroking him with her fingers.

Finally she gives in and slowly takes him into her mouth, she can feel him shiver as he lets out a low moan and she sucks him in deeper. He begins to lose control as she sucks him into her mouth, filling her mouth with him. His hips begin to move with her mouth, thrusting himself gently into her mouth, his breathing becomes ragged and uneven and she can tell that he is close to losing all control.

She slows down, taunting him, making his pleasure last. Swirling her tongue around his whole length, then gently sucking at the head. Finally she gives him what he craves and takes him back into her mouth. Applying more pressure and keeping a strong, steady rhythm. He can take no more and she lets him fill her mouth. She keeps sucking until he has no more to give. He pulls her to her feet kissing her hard tasting himself on her lips.

He picks her up and gently lays her on the bed. His sheets are soft and warm and they welcome her into their folds. He crawls his way up her body, his fingers creeping their way to her dripping opening as he probes at her entrance. His fingers slip inside her as his mouth comes down on hers, kissing her deeply and slowly, and taking his time. Making sure she can feel how much he loves her. How much he cherishes her.

His other hand pushes her legs wider apart allowing him to sink further into her. Her moans are muffled by their kissing and she longs to feel him deep inside her.

He removes his fingers and runs his hand over her stomach. Then he whispers, "This baby is mine. I don't care that I'm not his or her father. From this moment forward, it's mine."

She nods and he can see the unshed tears in her eyes. She knows that he means the words with the truest sincerity. Never before has she felt quite so loved and cherished. She knew that this was her last first time with a man. He was it for her. He runs his hand up to her cheek stroking her hair away from her face looking lovingly into her eyes. Kissing her hungrily he finally pushes himself inside her with a soft moan and she shudders as he sinks deeper and deeper inside of her, not stopping until he is filling her completely.

Slowly he eases his way back out until only his tip is left inside. Then he pushes himself back in. In and out and in slow teasing strokes, prolonging the pleasure for them both.

His thrusts get harder as he buries himself inside her and she wraps her legs around his waist holding him tightly in place, right where she wants him. Their bodies are drenched in sweat and their cries are getting louder by the second.

She elevates her legs to rest on his shoulders, and he lifts her bottom off the bed and plunges himself further into her than either of them ever thought possible. The deeper he is the better it feels as they continues their lovemaking. Kate's breathing is shallow and her vision is blurred with unshed tears as she begins to orgasm once more, screaming throughout the delicious sensations.

He rolls her over onto her side and lays behind her; once again she can feel him between her legs and she pushes herself back onto him and he easily slips inside her.

With one hand on her hip he rocks be back and forth gently and rhythmically, she grips the pillow as the pleasure suddenly becomes too much, She's moaning and crying as he tips her over the edge once again. They cum together. He holds her tightly in his arms. Then he whispers, "You are mine Kate. Mine and mine only. No other man will make love to you. Ever.."

"I'm your's Rick. Always…."

He holds her with a hand around her waist settling on her stomach and they fall into a deep sleep.
