So this is most definitely M - okay? Not appropriate for children...Explicit references and a bit of language.

If I were to us a Harry Potter-esque scale to rate this chapter for it's level of naughtiness, I would give it a D for Dreadful. The next chapter however, would more likely be graded a T for Troll - mhm... yup

Until then, you have this... enjoy [mwahahahahaha!]

When Octavia's seminar was over, the majority of the couples who attended, disappeared and quite suspiciously, were no where to be found for several hours.

Castle and Beckett however opted for a friendly game of tennis, to release their "frustration."

The went over to the courtyard, where they met a feisty young couple named Marcus and Carrie Whetstone.

The couples soon began agreeing on a doubles match, although every five seconds, Carrie would be taking another business call on her cellphone, leaving Marcus looking extremely dejected.

When finally Castle had had enough, he took Carrie aside and snatched her phone off her like she was a disobedient teenager.

"You know cellphones aren't strictly allowed here", he reminded her, dangling the phone over her head.

Carrie folded her arms, tapping her foot on the ground, looking pissed. "I need that phone. You have no idea how much trouble I'm in with my boss for taking a fortnight off to be at this thing."

Castle looked at her, shaking his head. He stood beside her and guided her around to look at her husband. "Think about how much trouble your marriage is in, then decide what's really important here."

Beckett overheard what Castle was saying to Carrie, and she thought to herself "He's turning into a councilor again..."

"Do you love him?" Castle asked her sincerely.

She spun around and glared at him. "What?"

Castle stared her down. She crumbled under his gaze and turned back around to her husband. Her shoulders slumped.

"With all my heart", she sighed.

Castle smiled. "Good, now what are you going to do with the phone?"

He let her have the cellphone and for a moment she stood, holding it in her hand.

After a few moments, she walked over to Marcus and held out the mobile device to him.

"Would you care to do the honors?" Carrie asked him with a grin.

He looked at her strangely for a seconds, until she motioned toward a nearby stream of water with her head.

A beaming smile overtook his whole face and he took the phone off her.

With one more reassuring nod from his wife, Marcus threw the cell phone clear into the water.

For a moment Marcus watched it float down the river in disbelief, until Carrie let out a yelp of glee and jumped into his arms, kissing him all over.

Castle and Beckett watched the couple's exchange from a distance, laughing.

When Carrie finally let Marcus come up for air, he mouthed "Thank you", to Castle.

Castle nodded with a smile and then looked at Beckett who was smiling right back at him.

Castle motioned for her to walk with him, leaving the couple to inevitably make-out in the courtyard.

They walked in contented silence for a while until Beckett broke it, by saying nothing. Her smile spoke louder than words ever could.

"What?" Castle chuckled.

"What you did for them was really nice. Really nice."

Castle looked at her suspiciously. "And yet, you sound cross?"

Beckett inhaled. still smiling. "You're just doing a great job at making it look like these marriage troubles are all my fault."

"Hey! I warned you that's what would happen", Castle joked with her.

Beckett shrugged, biting back a grin. "You just never seem to be able to be quite as prophetic when you're talking to me, as you are when you talk to other women."

Castle didn't miss a beat. "That's because no other woman puts me at a loss for words like you do."

Beckett's jaw dropped slightly, but she managed to cover it up by pretending to yawn.

Castle looked at her gently. "Tired?"

Beckett nodded. "A bit, yeah."

"What do you say we skip dinner and get an early night?" Castle asked, not realizing how couple-y that sounded.

Beckett blushed. "Good plan."

Just then Beckett's phone rang, it was the 12th again. "Esposito", she said to Castle "Might have to rain check on that early night."

Castle laughed.

"Hey Espo, what's up?" She said informally into the phone.

"Hey, so Lanie did a thorough exam of the body this morning and she found something that the Bayonne coroner must have missed."

"What did she find?" Beckett asked, stopping in her tracks. Castle looked at her intrigued. "Hold on, I'm putting you on speaker so Castle can hear you."

"Oh, hey Castle", Esposito said casually once Beckett had put him on speaker phone.

"Yeah, yeah, yeah, what'd Lanie find on the body?" Castle rushed him.

Esposito sounded affronted. "Piece of thread. Black leather to be exact."

Beckett's brow furrowed. "We never found any finger prints on the victim's throat. Killer could've been wearing leather gloves."

"Yeah, you're probably right. We matched this particular thread to the material used to make a very pricey pair of Gucci, womens gloves."

Castle raised his eyebrow. "Our victim was strangled during a cat fight?"

"Just because the killer was wearing womens gloves doesn't mean it was a woman who committed the murder, Castle", Beckett reminded him.

"Have you seen any cross-dressers while we've been here?" Castle asked her with a tinge of sarcasm.

Beckett rolled her eyes at him. "OK, we'll keep our eyes peeled for any expensive Gucci mitts lying around the place."

"Cool, I'll send you a picture", Esposito said. "Hey Castle..."

Castle looked at the phone, fearing a lashing.

"If I were Beckett, I wouldn't even be bothering with marriage counseling. I would just dump your ass."

Beckett didn't know whether to look amused or appalled.

Castle made a face at the phone. "Yeah well, I'm sorry Javier, but you're just not my type."

Beckett hung up just as Castle was finishing the last word.

"If you're quite finished", she said to him pointedly. "We still have a murder to solve."

She walked away, leaving him hanging. From his position, he had a perfect view of her butt as she shimmied away from him.

"And quit checking out my ass", she said behind her shoulder.

Castle blinked and hastily went to catch up with her.

Damn, she was scary when she did that.

...

They walked straight to their room and flopped down on the couch, this time choosing to sit next to each other, rather than across from one another.

Castle sighed. "So, we're looking for a woman. More than likely an elitist, or at least a deluded pauper. Probably has a flair for the dramatic. She has to be married of course, but she's unhappy with whomever it is she's with."

Beckett raised her eyebrow at him. "Nice profiling...Doesn't that describe just about every woman here?"

Castle pursed his lips. "Scary thing is, it's sounding a lot like my mother."

Beckett grinned, burying her head in the crook of her elbow, which was resting on top of the couch.

Castle stared at her; god she was cute right now.

"Hey, you should go get some rest", he told her gently.

With lackluster energy, Beckett lifted her head. "Mm, you're right."

"You want me to carry you to bed?" Castle smirked, a glint in his eyes.

Beckett chuckled. "I think I can make it." She rose from the couch.

"Sweet dreams, Mrs. Bexhill", Castle called after her.

...

Next thing Castle new, he was waking, bleary-eyed on the couch. He must have fallen asleep, pretty quickly after Beckett had left him alone in the living room.

He felt the instant urge to pee, so he got up from the couch and stretched, his bones creaking delightfully.

He strode to the bathroom door and reached out for the handle, just when he was about to turn it, he heard a soft moan coming from inside.

He squinted, and backed away from the door. Looking toward the bedroom he and Beckett shared, he saw that the door was open with no Beckett in sight. He approached the bathroom door again hesitantly. "Kate?" He said softly.

He heard her gasp from inside.

"Castle", her breathy reply made parts of him tingle.

And then another moan.

"Holy shit." Castle thought to himself, not taking another second to figure out exactly what she was doing in there.

Tentatively, he leaned up against the bathroom door and put his ear to it. He could hear her trying to hold back her groans - he so wished she wouldn't.

"Kate" - another moan. Castle stood, rooted to the spot for several delirious minutes. Finally he said; with more authority than he thought his voice could manage - "Breathe Kate."

As loudly and as purposefully as he could, he began to inhale and exhale as deeply as his lungs would allow. Almost instantly he could hear her own breathing matching his rhythmic tempo.

"Ohhh, Castle."

Castle's cock twitched in his increasingly tightening underwear.

"That g-good huh?" He chocked out.

"Mmmm", came her uncontrolled reply.

"Kate..." Castle murmured unsurely to the door. She seemed to understand what he wanted straight away.

"Do it Castle... Please."

Without any further encouragement, Castle shoved his right hand into his pants and began stroking his now fully engorged member.

"Ugh", he grunted, biting down hard on his bottom lip, making a fist with his unengaged left hand.

Inside, Beckett moaned again and whispered. "Breathe Rick"

Holy hell! If his cock was engorged before, it was nothing compared to the hot stiff rod he held in his hand, after hearing his first name spilling out of her sweet lips.

He made a noise somewhere between a cough and a laugh. "I'm trying, it's not easy when my pulse is so god damned high."

"Try harder...for me", Beckett egged him on.

Again he chocked. "That's not helping my pulse, Detective."

Beckett breathed deliberately slow and loud, until Castle finally managed to calm his breathing down to match hers.

"Better?" She asked him with a sly tone.

"Ohhh, fuck", he growled, banging on the bathroom door.

Beckett tipped her head back, screaming out, unashamedly.

Castle's speech was now a constant slurry of ecstasy.

"Oh Kate, so close... I'm so close Kate."

Beckett and Castle's screams were surely loud enough to be heard by the whole retreat, but at that moment they couldn't give a rats arse.

"Cum with me Castle... Beckett breathed.

At this, Castle lost any self control he thought he had and shamelessly shot his load against the bathroom door, swearing in beautiful agony as he did so.

At the same instant, Beckett screamed like a banshee, her whole body wracking with her orgasm.

For a moment, the two of them were silent, still breathing as calmly as they could, making their releases last.

Several minutes of slightly buzzing heads, and racing hearts went by, before Beckett cleared her throat.

"I didn't really sleep much before." Her voice rung out suddenly.

Castle lifted his sweaty brow from the door, thinking she was about to ask him to leave her for a while.

But instead, she said something she'd never have been brave enough to say, if it weren't for him interrupting her intense masturbation session, a few minutes prior.

"Why don't you go jump into bed, and I'll meet you there soon?"

Castle's felt like his heart had turned into a balloon, expanding in his chest.

He felt dizzy and weightless - Kate Beckett, the most well-guarded woman he knew had just shared with him one of the most private, intimate things a woman can experience; not only shared it; but delighted and thrived in sharing it. And now, instead of predictably trying to escape the awkwardness of it, by putting up her usual wall, it seemed she was finally ready to invite him onto her side of the divide.

"Kay", was all he could manage to say to her.

He walked, zombie-like to the bedroom and flopped onto the right side of the bed.

He relaxed into the softness of the bed. He felt euphoric; the wildest of his dreams that he'd been dreaming for close to four years had just became a very intense reality...

...

After a few minutes of collecting herself, Beckett moved, in a dazed state, from the bathroom, to the bedroom. She couldn't believe how unabashed she had felt doing what she had just done with Castle.

Never in a million years did she think she would ever do something so erotically daring with a man, but with Castle it just felt so natural, and so incredible.

As she came to the door of their shared bedroom, she paused for a moment, before opening it, expecting to see Castle, sprawled out on the bed, in all his naked glory.

What she found however, made her want him even more.

He had fallen asleep.

Lying flat on his stomach, mouth open, and arms and legs sprawled carelessly.

She beamed, and licked her lips. Not bothering to climb under the covers for fear of disturbing him, she gently climbed on top of the blankets and crawled silently over to his beautiful, peaceful form.

Leaning into him, she licked his ear lobe seductively. She grinned. knowing what a stir she would have caused had he been awake. But he was sleeping, a small smile on his face.

He was dreaming of her. Of them

Barely audibly, she whispered in his ear. "Well it was good for me, was it good for you?"

In his stupor, he sighed contentedly.

Beckett lifted his am from the bed and placed it around herself, cuddling into his side, where she instantly found that familiar warmth.

She really didn't know where exactly they would take things from here. How fast or slow they might move.

What she did know however was that there was no turning back now. Looking over at his adorable, snoring figure, she smiled, thinking how wonderful it was that they had no other option but to go forward from this point. She knew that this right now was the closest they'd ever physically been to making love, but they were lovers in every sense of the word, she knew they had been for four years.

Before she fell asleep to dream on all of life's new possibilities, she caressed her lover's face, and whispered softly...

"Goodnight Mr. Bexhill."

A/N: So it was good for Beckett, how was it for you? :-p
