A/N: I know it's been forever since I updated, but I'm currently in the process of sorting out moving to Spain for two months (I'm from England) and I'm going next week so life has been hectic! Will try and update again before I go, but I can't promise when the updates will come after that!

Thank you for all of the reviews so far.

"Morning beautiful," Castle husked as Kate rolled towards him, opening her eyes. A lazy grin lit up her face and she propped herself up on her elbows to place a kiss on his lips.

"Morning yourself," she said back. "And it's only 7.30, what do we have planned for today?"

"Well, you said you were going to go and talk to Gates again," Castle reminded her. "But that's after lunch, right?"

"Yeah," Kate agreed. "Which means we have the whole morning to ourselves.." She had sneaking suspicion the glint in Castle's eye matched her own. "Perhaps we should call Charlie and Ethan over, make breakfast?" Kate suggested, pretending to reach for her cell from the bedside table.

"Don't you dare," Castle growled, pouncing for her and pinning her underneath him as he straddled her hips. He knew how much this did it for Kate, him taking charge and being in control and he loved it himself, knowing that she trusted him enough to give up all control and just go with it.

Their kiss turned heated pretty quickly, tongues swiping and teeth scraping and biting, hands roaming each other's already-naked bodies - they rarely redressed after sex the night before, no real need for it when they had the place to themselves. Knowing what really turned her on, Castle used it to his full advantage, teasing and drawing long, low moans from her body. He was just about to step it up a notch and really drive her crazy when his cell began to buzz.

"Leave it," Kate gasped from beneath him. "They'll leave a message." Except they didn't. Not five seconds after the buzzing had stopped, it began again.

"Sorry," Castle grumbled. "But whoever it is isn't going to give up." Stretching across the bed, he retrieved his cell and answered, not bothering with looking at the caller ID.

But Castle was soon wishing he had ignored it, as a shrill and very annoyed sounding voice exploded into the room. "Richard Castle have you seen the paper? Or the internet? Oh my god what is going on? I thought you and her were good, you know, no problems and then this?"

"Paula," Castle muttered unnecessarily to Beckett who was not looking impressed. "Paula," he repeated, louder this time to interrupt the woman's rambling. "What the hell are you talking about?"

"The paper, Richard!" She exclaimed. "And what they've put on the internet. And that girlfriend of yours, Kate and oh what the fuck is going on?"

"Will you just slow down and explain what it is you're talking about in a language that somewhat resembles English, please?"

He heard Paula take an exaggerated breath before she carried on. "Page six," she explained as calmly as she could. "Just..go and see and call me back, I have damage control to sort out!"

Before Castle could even muster up a reply, Paula had cut the call off. "What on earth?" He muttered, staring blankly at his phone. "How much of that did you hear?" He asked Beckett, hoping for a voice of reason.

"All of it," she replied drily. "I think they may have heard her over in New Jersey." She was cursing Paula and her stupid damn phone call right now, all Beckett had been after was a morning in bed with her boyfriend, was that really too much to ask? "I guess we better go and get the paper," she sighed, "or Paula is going to be calling back and I wouldn't put it past her to explode."

The two of them grabbed some clothes and padded to the living room, Beckett throwing herself onto the couch and Castle heading over to retrieve the paper. Bringing it back over, he sat down next to Kate and flipped to page six. The headline made them both gasp out loud.

"Holy shit.." Beckett whispered as her eyes raked the page, taking in the story - and suddenly Paula's reaction was very much justified.

RICHARD CASTLE'S MUSE IN SEX TAPE SCANDAL the headline read. Beckett and Castle read the rest of the article in silence, both taking in the words printed on the page.

Mystery writer Richard Castle seems to have found himself in a situation even he can't write himself out of - his muse - and suspected girlfriend, Detective Kate Beckett of the twelfth precinct homicide division here in New York City has found herself in a spot of bother: a sex tape has been leaked online - and her bed partner isn't the famous Richard Castle. The novelist, who dramatically killed off his bestselling character Derrick Storm four years ago, began shadowing the detective and has based the hugely popular Nikki Heat novels on her, before they began a romantic relationship at a later date. Castle, who is famous for gracing page six with his exploits involving numerous beautiful women shocked many when he seemed to settle down - which sources say is down to the 'by the book' detective he has spent so much time with in recent years. But with a time stamp on this video practically proving that he has been cheated on, how much time is left on their relationship - and what does this mean for Nikki Heat?

See the full video at..

The article was accompanied by screenshots taken from this 'sex tape', showing a woman who looked remarkably like Kate enjoying some rather intimate acts with a man who quite clearly wasn't Castle. Thankfully for Beckett, Castle found the funny side.

"Oh wow, that's hilarious!" He grinned.

"I'm glad you think so," Beckett grumbled. What the hell was this? It wasn't her, she knew that, but who would 'leak' this and tell the newspaper it was her? "And don't they know time stamps can be faked?"

"Well," Castle replied, a grin still on his face. "Nothing else is being faked in that, I mean just look-" he broke off at a warning look from Kate.

"Who would do this, Castle?" She whined. "Someone has gone to extraordinary lengths to find a model or porn star or whatever to pass as me..just look at her, it's not actually bad!" The woman had the same hairstyle and although her face was partially obscured by her arm thrown over her head, she did look very much like Beckett herself.

"Let's watch the tape," he suggested tentatively, expecting another of her icy glares.

However, Beckett conceded. "Fine," she huffed, "at least it might give us some clues as to who..or where or something."

Castle didn't question, not wanting to give her any opportunity to change her mind. He quickly started up his laptop and typed in the address the paper had given. Clicking play on the video, he sat back with the laptop perched on his knees and Kate curled up next to him. If they weren't so baffled as to what was going on, it would be kind of erotic.

The woman on the screen gasped in pleasure and Castle's gaze shot to Beckett. "You know," he mused, "if I didn't trust you so implicitly, I really would think that was you. You make sounds like that too, especially when I-"

"Castle," she interrupted loudly. "Just shut up and watch the- holy fuck, that's Ethan!"

Castle frowned before focussing more intently on the screen. "You're right," he said. "So that means that- oh my god, Beckett!"

"What?!"

"The break in!" He garbled. "At your apartment..nothing was stolen..what if they broke in to plant cameras and record Charlie and Ethan - and then sell it to the paper saying it was you!"

"But why?" Beckett asked, although she had to admit - it was the only possibility she could think of right now that actually made any sense.

Castle began to speak but then realised he still had the video playing - the one of his girlfriends sister having sex. Yeah, better turn that off. "To get to you?" He suggested. "Maybe it's Maddox..trying to play games, damage your reputation.."

"Except it's not me," she pointed out but even as she said it, she knew it was stupid - most people didn't know she had a twin sister, the majority wouldn't have trouble believing it was her.

"Do you think Charlie's seen it yet?"

Kate groaned. How the hell was she meant to explain this to her sister?

Twenty minutes later and she had her answer. "..And I really am sorry about all of this," Kate said into the phone. "I just can't believe they'd do something like this.."

"Don't worry about it," Charlie reassured. "And besides, no one will think it's me, anyway!"

"Yeah well, hopefully it'll die down when some b-lister goes to rehab again or something," Kate said, trying to calm herself down more that her sister. "I'll call you later, bye."

"What did she say?" Castle asked.

"She was surprisingly okay about it," Kate laughed. "But then I guess she's not the one with a police career on the line - and everyone thinks it's me, anyway!"

"Hey," Castle said, "you know I never doubted you for a second, right?"

"Yeah, I know," she smiled. "Thank you for that, goodness knows what I would have done if you'd believed it too! Charlie watched the tape while we were on the phone - she's just happy it shows her in a good light or something." Beckett rolled her eyes. Despite the fact that her sister had taken it well, Beckett wasn't entirely sure what would happen when she stepped outside the security of the loft - especially given that had been planning on going back into try and get her job back again this afternoon. Just then, her cell buzzed.

'Oh dear,' it read, 'what will Captain Gates say?' Beckett quickly got rid of the message and put her cell back down, hoping Castle hadn't noticed that anything was wrong.

No such luck. "Okay Beckett," he sighed. "That's the third or fourth time I've seen that happen in the past few days - if it's not a text, it's a call - I want you to tell me what's going on." And he wasn't taking 'it's nothing' for an answer again.

A/N: thoughts? Again, I apologise for the inconsistent updating, but life is busy right now!
