Be warned this chapter is definitely M rated! Also this is my first time writing anything like this so I hope you enjoy it.

Castle and Beckett were strenuously trying to keep from making out while they were in the back of the cab. That didn't stop them from letting their hands wander a little bit though. Castle looked at Beckett so passionately as she slid her left hand over his chest. She starred at him deeply leaning in closer. His pulse was running wild as he half closed his eyes and leaned in. But just as they were an inch from each other, she suddenly pulled away playfully. Castle whimpered helplessly at her teasing. But he knew he would definitely be paying her back shortly.

His hand slowly slid half way up her bare leg and lightly squeezed to let her know exactly what he was thinking for his revenge. She felt her cheeks flush at his touch and she slid a little bit closer. She didn't want to get too carried away as they were minutes from her apartment.

As they finally pulled up, they paid the driver before stumbling out of the cab in haste. Beckett grabbed his hand and pulled him along up the steps and inside the building.

She shamelessly had a fantasy that included things getting a little steamy with Castle in an elevator and it was definitely happening tonight.

It was late and there was no one around as the two of them entered the elevator impatient for the doors to close. Once they had, Beckett pushed Castle against the wall and began kissing him roughly. She had her whole body pushed up flush against him making him groan with want. He was loving this confident, seductive side of Beckett. And even more he loved that she was in his arms right now.

The elevator opened on her floor and the two reluctantly pulled apart. They stumbled along together compromising between quickly getting to her door and holding each other closely. Castle had waited so long for this moment that he didn't want to give Beckett a chance to change her mind by letting her drift too far from his embrace. Little did he know that she had wanted this just as long has he had and she was definitely not backing out tonight.

Beckett stumbled with her key in the lock because Castle was making fine work of her neck with his lips. She thrust her hips back into Castle's making him gasp, giving her just enough time to focus on opening the door. He gripped her hips tightly trying to maintain his balance as he was almost feeling dizzy with how sexy she was in front of him.

Finally she opened the door and pulled him inside with her. This time he pushed her up against the door and ground his hips against hers letting her know exactly how turned on he was. His pants were getting to be horribly tight.

She moaned at being able to feel his hard self against her. She wanted him so badly but she wanted to have some fun with him first. She pushed him away a little bit and gave him a look that told him not to move.

Beckett ran her hands up along his arms and over his chest making him shiver at the contact. They slowly made their way down to the rim of his pants and she removed his belt. She suddenly kissed him hard but pulled away as quickly as she had attacked him leaving his head spinning. With his belt still in her hand, she wrapped it around his waist and used it to pull him over to her couch.

When she had him standing in front of it, she pushed Castle down rather harshly reminding him just how dangerous she was. She stood in front of him for a moment just letting him stare at her with longing. She was absolutely mesmerizing to him.

Beckett loved torturing him, and she was far from finished. She pushed his legs apart and put her right knee to rest on the couch in between. So close to putting pressure against him in just the right spot, but not quite. He groaned in anticipation. She was driving him wild.

Beckett leaned in slowly to kiss him, and he closed his eyes just wanting to feel her soft lips against his. But instead she decided to go for his neck making him gasp out loudly at the sudden love biting against him. He was unraveling underneath her and finally she decided to give him a little bit more of what he wanted. She pressed her right knee against him fully, making him moan loudly. His hands were painfully gripping her hips in pleasure.

Just as he was getting used to this wonderful new feeling it was gone again. He looked up at her in surprise to protest, but his mouth just hung open. She was slowly sliding the straps of her dress off her shoulders. So teasingly slow. He just stared at her, with his mouth watering. He wanted to attack her right then and there but he was a little worried about how she would make him pay for it. He wasn't ashamed to say he was afraid of what this woman could do.

Here he was witnessing the most beautiful woman in the world giving him a strip tease. He could hardly take just watching. Finally the dress slid off but before Castle could take in the view, she lightly threw her dress at his face distracting him long enough to pounce on him again. She straddled his hips and unclasped her bra. He slid the straps off her shoulders and threw the garment aside. His breath hitched in his throat as he took her in.

God is she trying to kill me?! She is so beautiful. It didn't help that she was also wearing sexy lace panties that barely left anything to the imagination.

He was at a loss for words so he just let his hands do the talking. They slowly slid up to grasp her beautiful mounds, and squeezed playfully.

She let out a moan at the feel of his hands which had quite an effect on Castle. His pants were ridiculously too tight.

He leaned forward and took one of her breasts into his mouth. He enjoyed the feeling of swirling his tongue around it and feeling it harden.

Suddenly he lost all sense of what he was doing as Beckett started grinding her hips against his with slow hard strokes. He felt like he could barely get enough oxygen to his brain to process what was happening. All of his senses were just going wild.

He had never relinquished all control before. This was entirely a new experience for him but he was enjoying it immensely and definitely not opposed to doing so again in the future.

Beckett began to unbutton Castle's shirt and she pulled it off him harshly before attacking the clasp of his pants.

She pulled his member out of his pants and began stroking him slowly. Castle was desperately loosing all self control. His knuckles were white against her thighs and his bottom lip was on the verge of bleeding from biting it so hard.

"Wait... I'm getting... so close," he barely managed to say as she was picking up the pace. As much as he didn't want the pleasure to stop, he wanted to be inside Beckett making her moan as loudly as he had just been shamelessly doing.

Beckett stood up from the couch and pulled him along to her bedroom. She silently thanked herself for remembering to clean up earlier that day.

She turned around once they had entered the room to see Castle had already taken his pants off and was wearing nothing in front of her. She paused for a moment her eyes transfixed on him.

"Like what you see?" Castle smirked enjoying the effect he had on her.

Despite herself, she blushed at being caught. She tried to recover her composure by taking back control and pushing Castle back onto the bed.

"Nope, my turn," he said against her ear as he lifted her up with her legs around his waist and roughly lowered them both onto the bed.

He wasted no time in pulling off her panties, but only half way. He then pushed her knees up to her chest to get a great view of her lower half. Castle looked Beckett straight in the eyes as he seductively licked his middle finger and then lower it to her folds. He wanted to tease her as much as she had done to him, so he only stroked the outside.

He was surprised to find how wet she already was, there was no need for extra lubricant.

"Rick, I want you so badly!" she whimpered helplessly.

Castle was more than willing to comply. Enjoying the fact that Beckett couldn't see what he was doing, he slowly lowered himself to press his tongue against her center.

Beckett let out a loud, uncharacteristic moan and gripped the sheets to hold herself steady. He was driving her insane with the things he was doing with his tongue.

Just as Beckett was going to complain that she couldn't take any more teasing, he stopped. He pulled her panties off the rest of the way and came to rest in between her legs.

Beckett quickly leaned over to her nightstand and grabbed a condom. She was glad she kept a few in there. Castle slipped it on hastily not wanting to waste any time not feeling her against him.

He enjoyed slowly stroking himself against her driving them both impossibly higher. But Beckett was having none of this. She impatiently thrust up against him forcing his member inside her.

Castle was so startled, his whole body shuddered. He felt so amazing feeling her all around him.

He gave her a minute to adjust to his size before beginning to move. He began with long slow thrusts trying to help himself last as long as possible.

Before he knew it, Beckett was climaxing under him. She felt her whole body shuddering with pleasure.

But Castle barely gave her time to recover, he pulled her knees up in between them and began thrusting into her roughly, determined to make her climax again. Beckett was nearly screaming, her moans were so loud in response to this new position. She knew her neighbors could probably hear her but she didn't even care.

"Are you going to cum again for me Kate?" he huskily whispered into her ear.

"Oh god yes! Rick don't stop, you feel so good!"

That was all the encouragement he needed. He was getting so close he could barely stand it.

He felt her unraveling around him once more and he could feel her walls grip him tightly. This pushed him over the edge as he felt her cum again. With a few more strokes riding out the wave of pleasure, he gently collapsed on top of her.

It was a little hard for Beckett to catch her breath with him on top, so she rolled them over so that she was resting against his chest. Castle threw away the condom and just wrapped his arms around her and buried his face into her hair.

Beckett leaned back enough to look him in the face. No words were needed to express the way they felt about each other. She just tenderly stroked his face with her fingers and lightly kissed him.

She loved knowing that he would be there beside her when she woke up in the morning.

Castle's eyes began to grow heavy as he listened to the steady rhythm of her breathing. He loved her so much and he couldn't imagine a better way to sleep at night then just being beside her.

And with that they both drifted off to sleep.
