Time stood still for Castle. He wasn't sure if the fact that it was past 4 in the morning and he hadn't slept yet was making him hear things or if Kate Beckett had actually just said she wanted him.

After what felt like an eternity, she spoke again. "Shit, Castle, I'm sorry. Look, maybe you should go..I appreciate you coming here to check on me and everything but- oomf," she was cut off from her speech by Castle pushing her back and planting his lips on hers. It surprised her at first and Castle was about to pull away and apologise for his mistake when she began kissing him back.

Hard. Fast. Furious.

She was kissing him with so much passion he was suddenly shocked. Was this really happening? Her tongue slipping past his lips to slide against his own and then she was sucking his tongue into her mouth and oh god this was heaven, and then she was biting his bottom lip and he growled into her mouth, hips thrusting towards her, searching for friction, anything that would help.

He was painfully aware of his erection currently digging into the zip on his jeans and longed to free it but he didn't want to assume anything. This was Kate Beckett, he wouldn't put it past her to tear herself away and declare it a mistake any second but oh god, her hand was trailing down his chest and lower until it reached the top of his jeans. Ripping her mouth away from his, she latched onto his neck and sucked hard as she palmed his growing erection. He groaned into her shoulder and gripped her hips hard enough to leave bruises but either she didn't care or it was turning her on even more. He was inclined to go with the second option given that she pressed the heel of her hand against him harder and thrust her hips up.

That was it, he couldn't hold back any longer. Gripping her wrist and pulling it away from his crotch - that deserved an award in itself - he looked at her, faces inches apart, her eyes dark with arousal and her breath coming in little pants that made her adorable.

"Kate," he growled out, "are you sure?"

"Yes," she whispered, trying to kiss him again but he moved back and she stopped.

"You're drunk," he stated, as if looking for a way out of this without saying the words.

"I was but I'm not anymore. Not completely sober but sober enough to know what I'm doing. Please Castle," she pleaded, "I've spent the whole night comparing every guy Lanie pointed out to you and I'm done pretending there's nothing here, I'm done pretending I don't want you because I do, so much."

So she'd compared other guys to him had she? Hmm, he'd have to talk to her about that. Later, though, right now he had slightly more pressing things to worry about. "As long as you're sure?" He asked one last time.

"Never been so sure about anything," she replied and when she pressed her lips to his, he didn't stop her. He simply gathered her up in his arms and carried her to the bedroom. He was surprised he made it without pinning her to the nearest wall, the way her tongue was sliding over the roof of his mouth was sinful.

Dropping her onto the bed, she landed with a thump and led on her back. She watched him remove his shirt and jeans, as well as his shoes and socks. Wearing nothing but his boxers, he climbed onto the bed and covered her body with his, kissing her deeply.

"Too many clothes," she grumbled, fumbling hands moving between them to try and remove her jumper. He helped her out, lifting it over her head and throwing it somewhere on the floor.

Staring down at her in just the underwear he had seen earlier, he couldn't believe this was happening. "You're beautiful," he whispered, "so damn beautiful." She removed her bra and he almost choked at the lust in her eyes, knowing how much she wanted him was a huge turn on and he was going to come in his pants if he didn't do something about it soon.

Hovering back over her again, he kissed her and her hands slipped behind his head and into his hair pulling him closer. She wrapped her legs around his hips and thrust upwards, applying pressure to his sensitive penis.

"Kate,' he hissed into her mouth, "baby you're gonna have to stop, I'm too close."

"But I haven't even touched you yet," she replied, "god I want you so badly."

With an animalistic growl, he pinned her to the bed and latched onto a nipple, swirling his tongue over it. The sudden assault surprised her and she cried out, a mixture of pain and pleasure. Her hands tangled in his hair and she pressed him further into her breasts. Her enthusiasm spurring him on, he took her other breast in his hand and palmed it, rolling a tight nipple between his thumb and forefinger. Switching breasts, he bit down hard enough to elicit a hissed curse from Kate and a desperate cry escaped her lips.

"Please, oh god, please.." She panted, screwing her eyes shut as he continued his exploration of her breasts. Moving his mouth away, he shifted slightly so he could see her as he pinched both of her nipples simultaneously, watching as she rolled her hips and opened her mouth to let out a gasp. She was close, so close, she couldn't..could she?

"Kate," he asked, still rolling her nipples in his fingers, "can you..?"

"Oh god, I don't know," she growled, "I never have before but I swear to god if you stop I'm going to kill you!"

He huffed out a laugh and moved back to his earlier position, taking a nipple in his mouth again. Knowing how close she was and oh god this was such a turn on, he'd never been with a woman who could come like this before, he doubled his efforts, alternating between biting and sucking one nipple and pulling and rolling the other. He switched sides again, wanting to make this as pleasurable as possible for her and paid the other breast the same attention with his mouth whilst his fingers worked over her other.

Her moans had increased in volume and her fingers were pulling at his hair as her hips bucked uncontrollably off of the bed. She came with a strangled cry and her arms tightened around his head, her whole body vibrating with pleasure.

He worked her down slowly, licking and sucking her sensitive nipples as she came back to him. "Jesus, Kate, that was.."

She caught her breath and looked up at him shyly. "I know," she couldn't believe she'd just come like that, it had never happened before, not even when she'd been so close to the edge, it had still taken extra stimulation of her clit to get her off.

"Have you seriously never.." He asked, still in awe of what had just happened.

"No," she admitted, "first time." She blushed slightly, she knew she hadn't exactly been quiet just now and she was still so turned on. Normally she could have gone with one orgasm and been fine, but he hadn't even gone anywhere near her yet and she was on fire, desperate for friction.

"Hey," he said, noticing her embarrassment, "it's nothing to be ashamed about, okay? Honestly, it's ridiculously fucking hot."

She smiled at him again and he kissed her, incredibly slow and patient for someone who had a rock hard erection that can't have been comfortable. She palmed him through his boxers again, feeling him jerk his hips towards her hand as his lips bit into hers. "Kate," he growled.

"Ssh, Castle," she soothed, "I want this to be good for you, too."

"And you have no idea how good that oh fuck," he broke off as her hand slipped below his boxers, fingers slipping over his hard length. Shit she was good at this, hand curling around him and pumping slowly, thumb brushing over his head every now and then, spreading the pre-cum that was leaking from his tip. She removed her hand and he mewled in protest, before watching her suck her thumb into her mouth, cleaning off the taste of him. "Need to be inside you, now," he panted, desperate to lose himself inside her. "You still sure about this?" He asked, pausing his movements.

"Yes," she replied emphatically.

"Because the second you're not, you let me know, okay? You let me know and I'll stop." He didn't know if he'd be able to, he was so desperate for her but he needed her to be 100% sure about this.

"Castle, I'm a cop. I'm fully aware of the guidelines surrounding consent and right now, I'd like you to hurry the fuck up," she growled, she wasn't letting him back out now.

He ripped her panties from her body, the sound of tearing fabric like music to his ears. Shuffling his boxers down his legs and kicking them off he spread her wide and ran his cock through her wetness a few times before sinking into her. She groaned in pleasure and he buried himself to the hilt, allowing her time to adjust to him. He wasn't small and he didn't want to hurt her.

"Move," she pleaded, legs tightening around his hips, "please Castle, fuck me."

That was it, those words whispered into his ear broke him and he pulled out of her before slamming back in and she cried out. He thrust in and out of her, so tight and hot and he wasn't going to last long. Her whimpers of pleasure were driving him crazy as he pounded into her, fucking her so hard she was going to be sore tomorrow.

"Harder," she grunted and if she kept talking he was going to come way too soon. She was enveloped around him, his cock coated in her wetness as he drove himself into her. Slipping a hand between them, he circled a finger over her clit before she stopped him. "No, don't," she panted, "I'll come too soon..I want to wait for you." Jesus Christ she was going to kill him.

Slipping all the way out of her, he didn't give her time to complain before he flipped her over and pulled her up so she was perched on her hand and knees. Taking his length in his hand again, he slid back into her, sensations from this angle heightened for them both. His hands gripped her hips tightly, pulling her onto his cock as he fucked her.

Collapsing her arms and shifting her weight from her hands to her forearms, she cried out. "Oh god, shit...oh fuck, Castle that's so good..please don't stop.." This new angle was pure heaven, her entrance was shoved towards him and he was thrusting into her so hard that the tip of his cock was hitting her g-spot and she was so close, she was falling apart and she needed him there with her. Leaning over her, he reached a hand beneath her and ran two fingers through her, just to the side of where he was pistoning in and out of her before dragging them up to circle her clit. Her hips jerked and he rubbed faster, knowing as soon as she let go he would too.

"Come for me, Kate," he whispered into her ear and she broke, screaming her release into the room. He continued to pound into her and circle her clit and as she tightened around him, he couldn't hold on any longer. Gripping her hip with his free hand, he came with a shout, spurting his hot come into her as he buried himself as deep as he could inside her.

It took them a good five minutes to get their breathing under control and even then they were still panting slightly. Castle wrapped Beckett up in his arms, pulling her close as he flopped down in exhaustion, until a thought had him wide awake again. "Shit, we didn't use a condom."

"I'm on the pill," she said, "and I'm clean."

"I'm clean too," he told her but he couldn't believe they had forgotten about protection. What if her pill hadn't worked and she got pregnant?

"I can hear your brain going into overdrive, you know? Relax, Castle, I take my pill religiously every morning, have done since I was 15."

"It's not that I don't trust you, it's just..I've never uh..not used a condom as well except from when I was married. Well, to Meredith anyway, Gina was insistent we use both, she didn't want a baby."

"You do know you're ruining the mood, right?" She rolled her eyes, she didn't exactly want to be talking about his ex wives when she was wrapped up naked in his arms.

"Shit, sorry. I'm just saying, I've never forgotten before, but you..you do that to me, make me do crazy things." He was so in love with her and it was killing him not to say it right now but he didn't want to push her away.

Moving her head from his chest, she looked up at him, "would a baby really be the worst thing to happen?" She asked before seeming to realise what she'd said. "Oh crap, I'm sorry, I didn't mean-"

He cut her off with a kiss, "yes, you did and I don't mind. Look, I know I only came here tonight because you accidentally called me but this isn't just a one time thing for me.."

"Me either," she admitted so quietly he almost didn't hear her. As if she could let him go now.

"Seriously?" She nodded. "Oh god Kate, I love you so much," he kissed her and tightened his grip on her, pulling her as close as possible.

"Oh god, wait until I tell Lanie," she groaned, burying her head in his chest.

"She thought you were going to to call Josh, right?"

"Yeah. Boy am I glad I didn't."

"Me too, Kate," he laughed, "me too."

A/N: remember, binge drinking is bad ;) so, what did you think? It was a hell of a lot longer than I anticipated, so your reviews are very much welcome!
