A/N: Sorry for the delay guys, school has just been really hectic and I wanted to get some time to concentrate on it. Anyway, here is the last and final chapter of my story. I hope you all enjoyed it. I have loved the feedback that I have gotten and I feel really welcome into the fanfiction community. I will be posting more stories but, the end has come for this one. On the bright side you can look forward to a very interesting ending. Thanks for the support.

The hardest part was coming home with all their clothes on. The ride home was a tortuous ride as it was during the drive back that all the sexual frustration that had been present between the two finally came out. Leaving one hand from the steering wheel, Kate slide her hand down onto Castle's lap. She started stroking his thigh as she heard a tight and low moan escape his tightly closed lips. She saw him frown. She knew he couldn't and wouldn't let his honor be tarnished so quickly. Leaning in, Castle let his lips wonder the soft and delicate skin of Kate's. He started off at her cheek but, soon made his way down to the nape her neck. He started slowly nipping at her neck while kissing it. Kate almost swerved the car into the opposite lane. A low moan escaped Kate's lips.

'How can he be doing this to be so quickly?' she asked herself. She could slowly feel the pool of wetness developing at the crotch of her tight jeans.

It was only after ten minutes of torturous foreplay in the car that they arrived at their destination, Castle's Loft. Not wanting to stay far apart for long, Kate scrambled out of the car to meet Castle at his door. Pulling him out of the car she pushed him against it and took his mouth into a shattering kiss. Her lips meet his and before either of them knew it they were fighting for dominance over one another. Kate tried repeatedly to gain entry into the private club that was his mouth but to no avail. Castle was good; there was no doubt about that. After all he was experienced. Moving swiftly, Castle was quickly in Kate's mouth; his tongue journeying everywhere. She could tell that he was trying to memorize every second of this as well as fulfill every fantasy that he ever had about her. Breaking apart, the look on Castle's face changed.

"Oh shit." The two words fell from his mouth. Seeing the sudden change Kate stopped and managed to restrain herself.

"What's wrong Castle? Are you feeling alright? Are the wounds opening up again? Do we need to go back to the hospital?" Kate pounded him with questions. She quickly straightened out her clothes and hair and looked back at Castle. He laughed and smiled back at her concern. She could tell he wasn't trying to break the mood that they both in.

"I'm fine, don't worry. It's Alexis and Martha. They might be home today and look at the condition we are in. We would have to do a lot of explaining to get ourselves out of this." He said putting his hands on her shoulders. Laughing Kate pressed forward and planted a kiss on his lips leaving him with a confused look.

"Kate, Did you just unders-" Castle started. She quickly interrupted him before he could get any further.

"I think I might have to take you back to the hospital, Castle. Do you even know what the day is?" She looked at him and saw the cogs of his brains slowly starting to rotate.

"It's a 12:23 on a Tuesday. Alexis and Martha won't be home. Alexis will be at school and Martha will most likely be out."

Seeing that he found the logic in what Kate had said Castle continued.

"I still reckon we should make it to the loft in a presentable manner. What if my mother is home and we burst through the door, both half naked?" he exclaimed. Kate laughed at the look of horror that was clearly present in his blue eyes. But, she had to agree. Even though she had planned walk through the door of Castle's loft half naked, she knew it would be the best thing to do if Martha was home.

"Well, I don't see what we are doing here wasting time, Castle. Quickly now. Wouldn't want to spoil the mood now would we?" She asked in a dark, seductive tone.

"Katherine Beckett, one day I swear you are going to kill me." He wined at her.

Laughing, she took his hand, locked it with hers and made their way to the elevator. Pressing the button for the lift, Kate looked at Castle, his deep blue eyes looking back. The man that was standing next to her was her partner. But, things were about to change. Soon he would be much more than just a partner. He would be the one to catch her when she fell, the one that would be there for her no matter what. It wouldn't be a one-way street either. The love and care that he showed her would be reciprocated back. Kate cherished the thought of being able to look after a sick or hurt Castle, if she ever let him get sick or hurt that was.

A loud ding was what distracted the two from each other. The elevator had reached the floor that they were on. Kate blushed a deep red as she realized that she and Castle had been staring at each other for a while. The grip on Castle's hands not wavering, Kate stepped on the elevator and pressed Castle's floor number. The doors shut with a silent thud in front of them as the engines pulled them upward with muffled whirring.

It was another loud ding distracted the two from their deep thoughts. The frantic mood that was present in the car was slowly fading away but, it was still ever present. Their hands entwined, the two stepped out of the elevator and walked to the door of the loft. Fiddling for the keys, Castle left Kate's hand. Her hand suddenly feeling cold, Kate become very aware of what her hand was doing and where it was. She didn't know what to do with it. Seeing the look on Kate's face, Castle quickly found the keys and swept up Kate's hands again. This was rewarded with a great smile from Kate; her white teeth peaking out from behind those delicate lips.

The door silently creaked open revealing an empty loft.

"Mother? Alexis?" Castle shouted just to make sure. Kate laughed silently to herself at how scared he was of being caught. Kate closed the door behind her and threw her jacket of the couch. She kicked off her heels leaving a reasonable height difference between them.

"Ashamed of me Castle? Don't want your mother and Alexis to see me?" Kate turned him around and pulled him close to her. She started playing with his collar and buttons and bit her bottom lip. She looked up at Castle whose face was filled with awe. Seeing that see was in control of the situation Kate continued to press onwards.

Slowly, she started pressing Castle against the wall behind him. Pressed against the wall, Kate swept up Castle's lips. The kiss was filled with passion and lust as they both fought for dominance. Castle had won once but, it was Kate's turn this time. Moving quickly, Kate was inside of his mouth in no time, tasting everything she could. She was matched with no resistance from Castle who let her have her way for once. Suddenly the need for air became too much for them both and they split from each other's lips reluctantly.

A quick moment was then shared between as they gazed into each other eyes. A millions words of passion and love was shared between Kate and Castle in those few seconds. A small smile grew on Castle's face as her looked into Kate's green eyes. Kate could tell that the mood was certainly back and that Castle wasn't going to waste a second of it.

Before she could protest or struggle, Castle swept Kate up into his arms. Too engrossed in the mood, Kate just let him have her way as she blushed, tinting her cheeks a soft red. She giggled and buried her head into Castle's shoulders. No one had shown her this much love in a while. Even her previous boyfriends, whom she had been hiding with, never showed this much compassion and love.

Never really showing his strength and muscular physic, Kate was taken a back at how bold and broad Castle was. She was upstairs and in his room in no time. Castle slowly, laid her to rest on his bed. 'The rumors are true; his bed is really comfortable', Kate thought to herself as he put her down. But, there was no rest for either of them. Immediately, Kate got of the bed and was pulling Castle's shirt over his head, leaving his normally tidy hair ruffled. She stopped moving and allowed Castle to have his turn as he pulled her top over her head.

In no time the two were left with only their under garments on. Stopping they both admired each other. Kate could see that Castle was living in one of his fantasies again. She smiled at the thought of Castle having fantasies of her. For herself, she was taken aback at the build of Castle's body. His shoulders were quite broad and his arms were equally big. How did he manage to hide this under those jackets?

Their eyes met and a smile escaped from both lips. Castle took a step closer towards Kate. She could smell his musky scent under his cologne. She looked up to him, smiling. Right now there was no other place she would be. Right now she only wanted to be with the man who had pushed his way into her life. It had been three years of partnership and friendship but, they both knew that there was always something else between them. She had let him stay with her even when he leaped over the line several times. There were so many times that she could have kicked him out or let him go but, she didn't. Nor did he. They were both meant for each other. He was the one that was there for her all the time. She had never had a person like that for a long time. After her mother's death she was mostly alone. Then this man found his way into her life and saved her from the jaws of the dark abyss that was going to swallow her whole. He brought light into her life with a few words. She couldn't help but, feel that she didn't deserve him.

Castle slipped his hands around her and pulled her close, chest to chest. She could feel the warmth radiating off him. Her eyes still locked with his, they both captured each other lips. This time it was a soft kiss. It was a small kiss that said a thousand words. She was trying to say thank you.

His arm resting on her back, Castle picked Kate up and rested her on the bed. Using just his two fingers, he undid the clasp of her bra pulling it away exposed her delicate soft breasts. His head dipped down to her chest as she felt him kiss her scar. Kate felt her eyes get watery but, she refused to ruin the moment. She put her hands around him pulling him closer. She felt his soft hands caress over the peaks of her breasts. She let out soft moan. He lifted his head up and captured Kate again in an amazing kiss.

Leaving his lips, Kate slid out of the only clothing she had left. The look that came upon Castle's face was priceless. She couldn't help but, but let out a small laugh.

"Haven't seen one before Castle?", Kate asked provokingly.

She was answered with a cheeky grin from Castle as his head disappeared between her legs. The next thing she felt was his tongue. He was working on her and he was doing a damn good job. Sliding up and down, in and out Kate started to moan. They were quite lucky no one was at home otherwise it would have become a very awkward situation. Castle's name started to become the mantra in the air as Kate started getting fiercer and louder. She wasn't sure how long she could hold back. She could already feel drops of her juice slipping out from inside of her.

Just when she thought she couldn't hold back any longer she felt the contact slip away and saw Castle's head lift up from between her legs. She could see that he knew how much he had just pushed her. She wasn't going to let him win that easy. Using her skills as a NYPD detective, Castle was soon on his back and the positions were reversed. Quickly discarding his jocks, Kate went to work. She could feel him tense under her as her head bobbed up and down. She could hear him moaning her name as she continued on. She could start to taste his juice in her mouth, as she got more aggressive. Slowing down, she slid down as far as she could feeling him at the back of her throat. She was rewarded with a loud moan and an arched back from him. Bringing her head back up, Kate gasped for air while maintaining a straight face. Leaving his lower body, Kate slithered up to him and forced her way into his mouth.

She was soon once again on her back as she felt the tip of Castle at her entrance. He kept it there for a while, stroking it up and down making her moan. She couldn't take the teasing any longer.

"You just gonna stay there Castle? Not come in?" She asked her voice becoming fierce. The look on his face didn't change but, stayed compassionate and worried.

"Kate," he said in a questioning tone, "Are you sure? I don't want to-" He was cut off by Kate once again.

"Castle, I love you. You are the one I am looking for. I have never been so sure." She said. And with that he slid into her, parting her entrance. Kate let a loud moan escape her. She felt herself stretch and could feel him throbbing inside of her as he slid in and out of her. He started slow but, gradually got faster and faster. Before long they both had reached their climax. She could feel the insides of herself clench around Castle's tool as they both rode out the juices that came torrenting out of them. Kate felt her eyes almost roll back as she half screamed, half moaned Castle's name.

As soon as it had come, it had left. Castle collapsed next to Kate as they both tried to regain their breath. Tired, Kate turned around to face Castle and snuggled into his chest. It was then the darkness of slumber enveloped them both.

Kate woke up to find two blue orbs looking down at her.

"Hey you," Castle said pushing a strand of hair behind Kate's hair.

"Hey," was the only reply she could give.

"Do you know how beautiful you are when you are asleep? How your chest rises and falls? Kate, you are truly amazing." She felt the warmth of blood rush to her face. She hid her face in Castle's check. This warranted a small chuckle from Castle.

The moment that they were in was perfect. Kate knew that she wouldn't change it for anything in the world right now. She sighed a content sigh as she felt happiness that she hadn't felt for a while seep back into her.

"Kate, The day you got shot I saw my world flash before my eyes." The smile from Kate's face instantly dropped as she realized where this was going. She couldn't stop him now.

"I couldn't let you die without my saying all those things I have held back. An now that we are 'this', I must tell you something." Kate felt the air from her lungs get sucked out.

"You won't remember this Kate but please listen to me. When you were on the ground, bleeding, in my arms, I said something that I held back from you for a long time. Kate, I love you." With this Kate, looked up at him. He was wearing a smile that couldn't be described. The smile was one of a five year olds face when he got ice cream.

"There is just no other way to put it Kate. I really love you. Since day one, I always have. You won't remember this because you said you don't remember this. So I'm telling you now. I love you. You mean the world to me. I can't get through one day without talking or seeing you. You drive me crazy Kate. I am in love with you." With this Castle brought Kate's lips to his and they both met each other. This kiss wasn't like the others. It was a simple kiss that said many things. It wasn't like the kiss that they had shared during the sex or during the foreplay. This kiss was the type of kiss you would give to someone you really love. To a person that means the world to you.

"I love you too Castle. Always." Lost for words, this was the only thing that she could manage to let out.

Smiling, Castle pulled her into his chest as they both rested. Kate wasn't smiling though. She held back tears as guilt came flooding into her. The fact was that she had heard him and she had kept it away from him. If he came to know about this, it would destroy him and destroy them. A silent tear slipped down her cheek but, it was for all the wrong reasons.

A/N: So there it is the final chapter. I hope you liked it. Please don't hate if the sex scene wasn't up to scratch. I tried my best. And also don't hate for the ending. Being me, I had to leave somewhat of a cliffhanger. As always don't forget to review. Once again thank you for the support and encouragement that has got me here.
