A/N: I fully realize that there is no way in hell that Christian would ever "share" Ana with anyone. Likewise, I fully realize that Arthur would never "share" Guinevere with anyone.

However, if people can write stories about Christian cheating on Ana, a concept that I find completely preposterous, and if people can write stories about Arthur and Merlin having a romantic relationship, a concept that I also find completely preposterous, I can write a story about these two couples doing naughty things. With each other.

There is just too much potential for hotness here to leave un-written. This concept has been plaguing me for months.

And obviously I don't own any of these characters, and I mean no disrespect to any of the characters or the actors who portray them (well, the ones that have actors). My Merlin peeps know how much I love Arthur and Gwen. I'm just a demented person having some fun. Hope you enjoy. :)

"Excuse me, are you Guinevere Pendragon?" a friendly voice asks. Gwen turns.

"Gwen, please. You must be Ana Grey," she says, smiling, extending her hand.

"Yes. Welcome to Seattle," Ana answers, shaking Gwen's hand. "I love your accent."

"Thanks," Gwen chuckles. "I love your dress. McQueen?"

"Yes. One of the tamer numbers from his design house. Usually his work is a little too…"

"Esoteric?"

"I was going to say 'wacky,' but your way is much nicer," Ana laughs.

"I actually hate most of his designs," Gwen leans in and whispers. "But being British, it's practically considered heresy. Especially since he died."

"Your gown is lovely, too."

"Thank you. It's Chanel, if you're wondering."

"Ah," Ana nods. She looks around and then leans over and says quietly, "I actually hate fashion. I abhor shopping and have no interest at all in designers."

Gwen laughs then, her eyes twinkling merrily. "I prefer flannel trousers and a t-shirt, topped off with on of my husband's hooded sweatshirts, honestly. I'm short. I always have to have everything altered."

"Well, then," Ana lifts two glasses of champagne from the tray of a passing waiter and hands one to Gwen. "To comfy clothes."

Gwen chuckles and clinks her glass against Ana's. "May we get out of these dresses and heels and into something comfortable as soon as possible," she agrees.

Ana looks across the room, her eyes finding Christian standing at the bar, talking to a very handsome blonde man.

"Your husband seems to have found my husband," Gwen says, nodding in the direction of the two men. "That is your husband, correct? In the black suit with the silver tie, talking to the blonde man?" He's very handsome.

"Yes, that's Christian," Ana nods, smiling again over his choice of tie. "The blonde guy is yours?" He's pretty hot.

"Yes, that's my Arthur," Gwen smiles as she watches him. "They seem to be getting on."

"Oh, good. I'm sure they're discussing business, but Christian doesn't really have a lot of friends. It'd be nice if he and Arthur got along."

"Well, he wouldn't have to worry about Arthur only hanging about because of his money. Arthur has plenty of his own," Gwen laughs. The Pendragons are about on par with the Greys when it comes to wealth. They've recently moved to Seattle to open the US division of Pendragon Power, where they'll be concentrating on bringing alternative fuels more to the mainstream, trying to make them more accessible to the general public.

"Oh, look out, someone's making a move on your man," Ana warns, pointing as an attractive blonde steps up to them, toying coquettishly with her hair.

"Or yours," Gwen smirks.

"She's definitely checking out your husband," Ana says, watching as Christian pointedly turns toward the bar.

"Well, she is now," Gwen chuckles and shrugs.

"You're not concerned?"

"Watch."

Ana watches. Arthur speaks politely to the woman, then pointedly lifts his wine glass in his left hand, tapping his ring finger almost absentmindedly against the glass a few times as she talks. Then he lifts the glass to his (intriguingly full) lips and drinks, basically brandishing his wedding ring in the woman's face. He also seems to be looking past the woman repeatedly as she talks, and Ana realizes he's looking across the room at Gwen.

Finally the flustered interloper turns to see what her target is distracted by, and sees Gwen making eyes at Arthur across the party.

Wow. You can practically see the electricity between them, Ana thinks. The blonde woman wanders away. "He's good."

"You have no idea," Gwen answers, almost to herself. Then she shakes her head briefly, as if clearing it. "Oh, yeah, I know I have nothing to worry about," she smiles brightly.

"Nice feeling, isn't it?" Ana asks, catching her own husband's eye across the room now. He waves a small, shy wave, and Gwen watches now as Ana slowly, deliberately, bites her lower lip, gazing at her husband through her long lashes.

Gwen can see Christian's peculiar gray eyes darken from cloud-gray to gunmetal as he watches Ana do that one simple thing.

Clearly he has some sort of fetish for her lower lip, Gwen notes.

xXx

"Your wife is uniquely lovely, if you don't mind my saying," Christian comments to Arthur, once that blonde bimbo finally got the hint that neither of them was up for sale. "She's the petite one in the blue dress talking to my wife – the pale brunette in silver – correct?"

"Yes, my little Guinevere, and I don't mind you saying it at all. Thank you, she is indeed that. And to be honest, I was just admiring your wife's lovely blue eyes. They're quite striking, even from this distance."

"Up close, they are mind-blowing," Christian comments with a smirk. "Looks like they are getting along," he adds when the two women laugh.

"Mmm, yes, good," Arthur nods. They both watch their wives a moment. "We are a couple of lucky men, Grey," he finally assesses.

"Indeed, Pendragon, indeed," Christian agrees, noting Mrs. Pendragon's almond-shaped eyes, ridiculously full lips, and flawless cinnamon-toned skin. Not my type, but there is something about her.

Arthur watches as Mrs. Grey's eyes twinkle as she laughs at some witty comment made by Guinevere, admiring the luster of her long chestnut hair, her long, graceful neck, and her creamy pale skin. Yes, lovely. Perhaps in another life, if we were both single.

"Is that your security man?" Arthur nods in the direction of Taylor, leaning nonchalantly against a wall near the elevator.

"Yes," Christian says, furrowing his brows. "How did you know?"

"He's not drinking. His eyes casually sweep the room at regular intervals. He watches Ana closely, and you."

"Hmm."

"I know the signs, what can I say?" Arthur shrugs. "If it makes you feel any better, mine's the tall bloke near the corridor leading to the loos."

Christian turns his head and looks. "With the beard and the long hair?"

"Yes."

"Kind of thin, isn't he?"

Arthur smiles. "Don't let that fool you. Leon is wickedly smart and positively deadly."

"Who's that he's talking to?"

"Oh, that's just Merlin. He's my R&D wizard. Dragged him over here with me. He's odd, but brilliant."

"They do go hand in hand," Christian observes. "Brilliance and oddity." He smirks, as if he's having a bit of an inside joke with himself.

"I presume Ana has her own guard?" Arthur asks. "Guinevere does."

"Of course she does. He's around somewhere as well," Christian says evasively.

"But you're not going to tell me," Arthur smirks.

"I only just met you, Pendragon. So far I like you, but if you think I'm going to point out my wife's bodyguard to you, you're—"

"Grey, I get it, don't worry," Arthur interrupts, holding his hands up. To Christian's surprise, Arthur is laughing. "First, I would never harm a hair on your beautiful wife's head. Anyone that would try would have to be monumentally stupid. You have a reputation, mate, and I… well, I admire that, honestly. I hope to build a similar one for myself in this country."

Christian studies Arthur a moment. He's smart. Shrewd. I could do business with him very easily. His wife is… intriguing. Finally he nods. "I think you'll do quite well." He fishes a card out of his pocket. "My business is very interested in alternative fuels. We can help each other."

"Brilliant," Arthur declares, passing his card to Christian.

"And your wife's bodyguard is pretty conspicuous," Christian says, smirking. "But I don't suppose he can help, it, can he?"

"What?" Arthur exclaims. "You bastard!" he yells, laughing.

"Sorry, I couldn't resist," Christian says. "Sawyer is standing right next to Mrs. Pendragon's guard. He's Ana's. Obviously they've decided to compare notes, since the ladies have been chattering nonstop over there."

"Marcus Percival," Arthur says, looking over to see his wife's immense bodyguard talking to another man, similarly dressed in a nondescript black suit. "Yeah, he's bleeding huge, all right. On the plus side, Guinevere can hide completely behind him should she need to."

"Has she ever had a need to?"
"No."

"She's lucky."

"Yes, she is," Arthur nods knowingly. Both men turn to watch their wives across the room. They both stare, admiring unashamedly, until Gwen's head turns sharply and fixes Arthur in her gaze. Ana sees the shift in her new friend's attention and follows suit.

"We've been caught looking," Arthur says as the two women make their way over, a pair of lionesses on the prowl.

"We are a couple of lucky men, indeed, Pendragon," Christian says, clinking his glass with his new friend and business associate.

xXx

"What are you two boys up to?" Gwen asks once she and Ana reach them. Arthur leans down to kiss her.

"Just openly ogling our beautiful wives," Arthur says.

"Oh, well, that's allowed," Ana says, once she's finished kissing Christian.

"Arthur, my wife Anastasia," Christian introduces her.

"Ana," Ana amends, shaking Arthur's hand.

"Christian, this is my wife, Guinevere," Arthur introduces.

"Gwen," Gwen laughs, glancing at Ana for a moment after shaking Christian's hand.

"Seems the two of you have hit it off quite nicely," Christian observes, wrapping his arm around Ana's waist, his thumb idly stroking her hipbone.

"Well, yes," Ana says. "Apparently we have a lot in common," she adds, her voice edged with playful sarcasm.

"Smart mouth," Christian says, his voice low, as he kisses the top of her head.

"Yes, Ana and I both love cooking and flannel pajama pants," Gwen adds, grinning. "Oh, and books."

"So, nothing at all to do with both of you being the wives of wealthy and powerful men, then?" Arthur asks, raising an eyebrow at Gwen, absently twirling a raven curl around his finger.

"Oh, are you wealthy and powerful as well, Mr. Grey? I hadn't realized," Gwen teases, batting her eyelashes exaggeratedly at Christian.

Christian's mouth opens and closes once, then he recovers. "It is a very well-kept secret, Mrs. Pendragon."

"Oh, God, the two of you haven't been over here having a pissing contest, measuring your…" Ana trails off.

"Bank accounts," Gwen finishes.

"Ah. Another thing they have in common," Christian sighs, looking at Arthur. "It seems they both have smart mouths."

"Yes, but when those mouths are as gorgeous as they, what can a man do?" Arthur shrugs.

I can come up with a thing or two, Christian muses. Ana surreptitiously squeezes his backside, indicating that she knows exactly what Christian is thinking.

Arthur's fingers skim Gwen's bare shoulder and Christian's trained eye sees her breathing deepen at the gesture, her incredible lips (they're even better up close) parting just slightly.

"Excuse me, I need to powder my nose," Gwen says, ducking out from under Arthur's arm.

Christian tightens his grip on Ana's waist to prevent her from accompanying Gwen. I have a suspicion.

"Mr. Grey?" a female voice interrupts them and Christian turns to see Ros standing a short distance away.

"Excuse me a moment, Pendragon," he says.

"Sure thing, mate," Arthur answers. When Christian turns back to him two minutes later, he is gone.

Confirmed.

"Ana!" Kate's familiar squeal greets them next. Ana rushes to embrace her best friend, and Christian heads off on a small quest.

xXx

Two corridors and countless closed doors later, Christian hears it. The unmistakable sound of two people making clandestine love.

I knew it. She wasn't going off to powder anything.

He stealthily approaches the closet, a janitor's supply room. He listens.

"Ooo…"

"Mmm…"
"Right there, Arthur… more…"

A slow smile spreads across Christian's face. He hears Arthur grunt, almost a growl. He hears Gwen's breathy gasps, tries to imagine her curvy little body in the throes of passion, those lips of hers kiss-swollen and wet.

"Oh… oh yes, Arthur… shit… oh!"

He hears Arthur follow immediately, coming with a massive growl, a growl that sounds like it was pressed into her neck.

Christian closes his eyes, willing the blood back out into the rest of his body, away from his groin, where it is currently happily residing.

I have to tell Ana. He hurries away, striding purposely, like he owns the place. The fact that he does is actually irrelevant. He finds Ana and pulls her into a quiet corner.

"Christian, what—"

He stops her with his lips, kissing her thoroughly; pouring the pent-up desire he's just accumulated into her.

"What?" she presses, breathless, once he finally releases her lips.

"Remember what we were talking about last week?"

"We talked about a lot of things last week—oh! Oh," she interrupts herself, remembering now that she sees the particular light in her husband's gray eyes.

He nods.

"Not… not Arthur and Gwen?" she asks, incredulous.

"I do believe we have some very viable candidates," he purrs, brushing his lips against hers.

"Oh, good. I really like Gwen. She's gorgeous and funny. And Arthur's pretty hot, too."

"Hot?" he smirks, interrupting his tasting of her neck to raise an eyebrow at her.

"He's not you, obviously, but even you cannot deny that he is very handsome."

"Yes, he is."

"And I saw the way you were looking at Gwen's lips, Christian."

"Jealous, Mrs. Grey?"

"Never," Ana says, sighing as he returns his lips to her neck. "I wouldn't mind seeing how those lips of hers feel, myself…"

"Mrs. Grey, you shock me," he mutters in a not-at-all-shocked manner.

Ana snorts. "Do you think they'd be up for it?"

"Ana," Christian lifts his head again, "I just discovered them fucking in a janitor's closet in the middle of a high-society cocktail party."

"Did they see you?" Ana asks, concerned.

"No. I was listening at the door."

"Pervert."

"You know, it, baby. And you'll reap the benefits later, you know."

"Mmm, when can we go home?"

"Soon." He leans in close again, his lips brushing her ear. "Do you still have the silver balls in?"

"Yes, and they are making me quite… needful," she admits. "I think this is the longest I've kept them in."

"If you can last a little longer, I'll try to get us out of here as soon as possible."

"Did I earn myself a spanking with my smart mouth earlier?" she asks seductively.

"Oh, most definitely," Christian rumbles, his voice a delicious promise.

A grin spreads across Ana's face. "Can't wait."
