Kate Beckett opened her eyes slowly, arching her back like a cat as a small smile played about her lips.

She felt wonderful.

In fact... She hadn't felt this good in...well...

Actually she had been feeling this good for two days now.

And she knew the reason.

She purred happily... Feeling almost languid... Stretching muscles that ached pleasantly... And in all the right places... then froze when she recognized the heat behind her.

Kate pressed back, groaning when the entire length of her body pressed up against his.

And Castle felt wonderful... The weight of him, the heat of him... the hardness of him pressed against the small of her back.

They had made love every time one of them woke up throughout the night; so many times she had actually lost count. It had left her thoroughly exhausted... and wanting him so badly she could taste it.

Kate shook her head slightly.

She was a healthy, thirty-something woman. She had always loved sex. But her appetite had never been this... voracious.

She shifted against him restlessly, closing her eyes and biting her lip when she realized just how much trouble she was in.

It was crazy... the need... the desire.

Maybe it was the three years they had spent dancing around each other...

Maybe it was the newness of 'them'...

Maybe it was just... them.

That was the one she hoped for... and believed in.

She shifted against him again, loving the way he felt when his manhood slid between her ass cheeks.

Unable to stop herself, Kate hooked one leg over his thigh, moving up slowly until Castle's morning erection slid between her legs.

He was so long... so thick...and so very, very hard...

Beckett closed her eyes and slid against him; feeling the wetness between her legs increase as his tip hit her clit over and over.

The hand around her stomach clenched, and then tightened. "Kate?!"

Castle's voice came out as a strangled squeak as she clenched her thighs and Kate laughed. "It better be!" She rocked harder, loving the groan that tore from his lips. "Or you are in a hell of a lot of trouble."

Kate sped up the movement of her hips; whimpering when Rick bit into her neck. Reaching down, she took ahold of him and guided him to her opening.

Castle's eyes rolled back when her wetness coated the length of him. He grabbed Kate's leg and drew it further up his thigh before sliding into her with a long shudder.

"God..." He groaned as his head tucked into her neck. "You were made for me."

"I don't know about that, Castle." Beckett grinned, bumping her ass backwards to signal him to start moving. "Maybe you were made for me."

"Don't care...either way..." He slid his hand around her throat, pulling her back gently to glide his tongue around the shell of her ear as he began to grind into her. "As long as you're mine."

"Jesus!" She arched back against him, unable to control the pleasure that shot through her from her core to the roots of her hair; making them stand on end.

"Two out of three." Castle quipped breathlessly. "Now we just need to fit in the Holy Ghost... Not that anyone else would fit..."

Kate pulled his arm up, biting his wrist just hard enough to get him to shut up. Unable...or unwilling, to stop herself, she pushed with her hips and arms, forcing him onto his back; growling at the new position. Without hesitating, she pulled herself up until she was sitting; effectively riding him... backwards.

Castle's mouth fell open and his eyes squeezed shut as she began to move, undulating her hips against him and arching her back, placing her hands on his chest to hold herself up.

He gathered up her hair and pulled it to the side.

As much as he loved looking into her eyes when he was inside of her, Castle had to admit that watching himself slide in and out of her from behind... watching her hips... her ass... With a loud groan he wrapped his hands around her waist; using the leverage to slam deeper into her every time she slid down.

"Castle!" Her voice was raw as she grabbed both his hands and dragged them up her body. He leaned forward willingly, sliding his legs back so that he was kneeling. As Kate did the same thing he slide one arm around her belly and the other under her breasts, increasing the speed of his thrusts.

"OH... Rick..." Beckett rocked back against him, losing herself in the feel of him, in how tightly he filled her. When he put one hand on her shoulder, pulling her more roughly against him, as his other hand slide down so that his fingers could stroke through her wetness she began to buck wildly.

"God, Castle...Castle..." She chanted his name over and over as the tip of his index finger found the swollen bundle of nerves at the top of her cleft. He circled it once... twice... And she felt the pleasure coiling pleasantly in her belly catch fire, expanding exponentially as she pushed harder against him.

Castle felt her start to flutter around him, felt the velvet of her inner walls tighten around him like a vice and lost control; pounding into her wildly. On his sixth thrust Kate shattered spectacularly; coming apart around him as she shuddered wildly. He followed one thrust later, pouring himself into her as he whispered nonsensical things in her ear over and over. Slowly he lowered them back to the bed, both of them unfolding their legs with a deep sigh.

"What else?" Castle breathed heavily.

"What?" She rolled over, throwing and arm and a leg across him.

"What else do you like about me?"

Kate laughed shakily. "I think it's your turn to tell me something you like about me."

Rick's face changed, becoming completely serious as he trailed a finger from her temple to her chin. "There is nothing that I don't love about you."

Kate swallowed heavily. She leaned up and kissed him, her tongue exploring his mouth for a minute before she pulled back and nuzzled into his chest,

Castle was almost asleep when he heard her whisper.

"I like your ass..."

Kate startled awake, looking around the room sleepily. She could swear she had heard... something. Something like a door closing.

She shook her head and focused. Hearing nothing anywhere in the loft she began to stretch and then blushed when she realized she was still lying on top of Castle; her arms and legs wrapped around him tightly.

Slowly moving off of him, Beckett smiled when she was able to slide out of bed without waking him. She looked at the pile of her clothes on the floor for a moment and then shook her head. Going to his drawer she pulled out a ratty looking green T-shirt and a pair of boxers. She had to roll the boxers over 4 times and they still looked huge but they would work.

Stumbling out of Castle's bedroom she yawned as she ran her hands through her bed hair and headed straight for the kitchen. She grabbed his French press, gourmet coffee and two mugs from the top shelf.

"Why hello, Detective Beckett."

Kate squeaked, spinning around and dropping the mugs loudly onto the counter as she stared at the couch across the room.

"Meredith." She looked at the redhead in shock and took a deep breath before turning to the blonde sitting next to her. "Gina." She looked down at herself, at how she was dressed. "Oh..."
