Modern AU: Two months after their break-up, Arthur sees Gwen in a club in her freakum dress. Cue angsty words and actions, all leading up to sex in Arthur's private room. Cause nobody makes love in a club, right?

Gwen sees Arthur watching her dance. She bends her knees and shakes her booty a little more and lifts her arms up over her head. She bumps into someone and opens her eyes. It's a handsome someone, so she smiles at him and drapes a hand over his shoulder.

He responds by putting his hand on her waist, and the two of them grind to the music. She maneuvers them so she can catch a glimpse of her ex's stormy but still infuriatingly handsome face, and sees fury behind his eyes.

Actual fury.

She wasn't exactly thrilled when Elana and Mithian had thrust the tiny silver dress at her, commanding, "Put this on, woman." But she's been living in sweats for the past two months (while not at work, anyway) and they made it very clear that they're sick of her attitude.

They dragged her out to this club, and of all the clubs in this stupid city, Arthur was holding court at this one. She suspected he had a private room in the back, as he does. He says that he likes to have a little respite from the noise. Really it's just so he can flaunt his largesse.

So Gwen had thrown back a few drinks and hit the dance floor in these ridiculous heels, and since she's been out there, Arthur has been watching.

So Gwen has decided to give him a show. Remind him of what his jealousy cost him. Give him something to actually be jealous about.

As it turns out, the handsome someone with whom she is dancing is Mithian's boyfriend Gwaine. But Arthur doesn't know that. He's never seen Gwaine. Mith sent him out to poke the skunk a little bit.

"He's going to kill me," Gwaine says in her ear.

"No, he won't," Gwen says. Then she laughs as if Gwaine has just said something incredibly clever and/or flattering.

"You are going to get me killed," he says again.

"Shut up," she says, slapping his chest playfully.

"Some skinny black-haired bloke is dragging him back to his room," Gwaine tells her.

"That'll be Merlin. He's a darling."

"Oh?"

"Not that way. He's straight. Just very sweet and genuinely a good guy."

"And he's Arthur's friend?"

Gwaine's only had Mithian's viewpoint on The Arthur Situation. So his opinion may be colored.

"All right, I need some water," Gwen says. "Show's over anyway."

Half an hour later, Gwen is coming out of the ladies' room, when she hears it. The voice.

"Guinevere."

She keeps walking.

"Guinevere, please."

She stops and spins on her heel. "What do you want, Arthur? Going to call me a whore for dancing with a strange man?"

"I never called you a whore," he says, and surprisingly, he's not shouting.

"Came pretty close to it."

He sighs. "I just wanted to tell you that you look really beautiful tonight."

"Thank you."

"And I'm sorry. I shouldn't have jumped to conclusions. I should have taken you at your word."

"It took you two months to come to that realization?"

He steps closer. "Two days. After I sobered up."

Gwen doesn't say anything. She lets him walk closer. "Merlin misses you."

"I miss him."

"He says I'm a complete wank without you around."

"I'm sure he's correct."

Arthur snorts a small laugh.

"If it was only two days, why didn't you call?"

"Would you have answered?"

"Good point."

"Plus I was afraid. I'd seen you angry once. That's enough for me."

Guinevere closes her eyes now. He is too close. "Arthur," she sighs his name, her voice shaky, and she hates herself for it. She feels the familiar warmth of his hand as it touches hers, his long fingers wrapping around her hand, and her eyes open.

"Guinevere, I never told you before… I wanted to, so badly…" he trails off, his other hand closing around her free one. "And now I'm afraid I'm too late, but I want to tell you anyway…"

He is very close now. Gwen can feel the warmth radiating from his skin. He is always so warm.

"I love you, Guinevere," he whispers, dropping his forehead to rest against hers. "I've loved you for so long and I never was brave enough to say it."

"And then you threw it away," she says, feeling the tears rolling down her cheeks now. "You threw me away because of something you saw for which you didn't care to hear an explanation."

"I know. I'm a cabbage head. Ask Merlin, he'll tell you."

She laughs, just once, and closes her eyes again.

"Forgive me, please, Guinevere. I don't deserve it, but I need you with me. I'm completely useless without you."

"Ask Merlin, he'll tell me," she says. He lifts his head from hers and nods, wiping the tears from her cheeks with one hand.

"Please. I'll get down on my knees on this rather disgusting floor and beg if I have to," he says, starting to lower himself down.

I should let him. "Arthur," she grabs his hand. "Don't do that. We have a large enough audience already."

"Come," he says, taking her hand and leading her back to the room he has reserved.

He opens the doors and Merlin is in there, chatting with Leon and Random Girl.

"Out," Arthur says. The three get up and head for the doors. Leon says hello and Merlin gives Gwen's free hand a squeeze as he passes.

Arthur closes the door. Then he locks it.

"Arthur…"

He crosses to her immediately and proceeds to kneel in front of her now, taking her hands in his again. "Can you forgive me?"

"The man I was dancing with was Mithian's boyfriend," Gwen says, still not answering him.

"So you were just making me jealous?"

"Of course I was. You know I wouldn't dance with a strange man like that."

"You haven't answered my question," he says. "And my knees are starting to hurt."

"Stand up, Arthur," she says. He does, and she leads him to a chair and sits him down on it. Then, surprising them both, she sits in his lap. Straddling him.

"Oh," he grunts. "Mmm," he hums when her lips find his, and his hands automatically find their way around her, reacquainting themselves with her amazing body.

"I love you, too, Arthur," Gwen gasps, pulling her lips from his. "I never stopped loving you, that's why it hurts so much."

"Will you give me another chance?" he asks, his lips unable to resist her neck.

"Just one," she says, dropping her head back and grinding her hips into his.

"God, Guinevere, when you do that…" he groans, kissing his way to her breasts.

"I know," she says, her voice breathy. "That's why I did it."

He lifts his head and looks at her. She just bites her lower lip. His hands slide down and then up her thighs, under the hem of her dress, a hem that was already hitched up nearly to her hips.

Gwen stands and shimmies her thong panties down her legs, then tucks them in the front pocket of Arthur's jacket, like a pocket square. She opens his trousers and reaches inside, freeing his manhood, sliding her hand on his length.

"He missed you, too," Arthur says, pressing his hips upward, further into her hand. "He was very lonely without you."

"Good," Gwen says, then climbs back into Arthur's lap, sinking down onto him with a low moan.

"God…" Arthur exhales, his hands sliding on her thighs again, shoving her dress up so it is bunched around her waist. He caresses her backside with his palms as she moves up and down on him, her hands gripping his shoulders.

"I need one of these," he grunts, pulling at the top of her dress, sliding a strap down her shoulder, pushing down to free one of her breasts. His lips are drawn like a magnet and he bends his head, taking the nipple in his mouth.

Gwen gasps, her fingernails scratching his scalp. She moves faster, harder, driving them both to the brink.

"Ohhhh…." Gwen moans long and low as she climaxes over him, her whole body tightening around him. It drives Arthur over the edge with her and he tears his mouth from her breast.

"Guinevere…" he breathes, wrapping his arms tightly around her and they cling to each other, coming down, riding the wave together, forehead to forehead, savoring the closeness.

He kisses her sweetly. "I love you. I'm sorry."

"I know. I love you. Don't do it again."
