A/N: Another requested fic, but an idea I've been playing with for a while. I think it's been done before, but not like this! ;)

"God damn it," Olivia spat, turning to face him as they barreled through the casino. "You just had to go there, didn't you, Stabler?"

"Liv, please, don't do this now, not while we're...'" he stopped. He wasn't going to say "undercover" in the middle of a crowded room. "Liv, you know I'd never say anything to hurt you!" Elliot cried, "Come on, I didn't mean...we were supposed to be fighting and I just...I thought it would be something a couple would fight about!"

"No, El, this was more than just a fight," she said shaking her head. "You used the family thing against me, again. You brought up children, and I'm fucking sick of it, and after seven goddamn years, I'm sick of you!" She walked away from him, wiping her eyes, and sat at the bar. She ordered a whiskey on the rocks just as he sat down beside her.

"You didn't mean that," he said, his voice desperate. "You couldn't have meant that, Liv. Tell me you didn't mean that!"

"Jesus Christ," she said, swigging back her drink. She sighed. "Oh, I meant it, El. I'm so sick of you constantly reminding me that I'm not married, and I'm not a mother, that I have no one, and I'm sick of fucking keeping the reason I'm not either of those things a damn secret because it could cost me my damned job!" She slammed back the rest of her drink and said, "And I'm sick of seeing you, every day, every night, knowing that you have the perfect marriage and the perfect kids and the perfect life..."

"Had," he interrupted. "Liv, you know they're gone. You know they've been gone for weeks."

Olivia looked at him and asked, "Then why are you still wearing your ring?"

"Because in case you forgot, we're on a case, here, Liv. And you're supposed to be my wife right now," he whispered. "The divorce was finalized the day before we got this assignment. Once the show's over the ring's coming off."

Olivia scoffed. "Right, the show. Some happy couple we look like we are, huh?"

Elliot ordered a beer and sighed. "I shouldn't have brought it up. I'm sorry."

Olivia nodded.

"You don't have 'no one', Liv. You have me. You'll always have me," he told her, brushing her hair back. "So, uh, you wanna tell me the reason, then? Why you're single and not a mommy?" Elliot asked as the bartender gave him his drink.

"Ha!" Olivia chortled. "Neither one of us is drunk enough for that, El."

Elliot chuckled and signaled the bartender to fill up Olivia's glass. "I can wait, Liv."

Olivia chuckled and shook her head. "You," she sighed.

"What?" Elliot asked, furrowing his brow and chugging his beer.

"I'm not married, and I don't have kids, because I can't stop comparing the guys I date to you, and they just don't measure up. I find things that they do annoying, because this little voice in my head says, 'Elliot would never do that." And I can't let them get close to me because there's things about me that only you know, and I want it to stay that way."

Elliot looked at her, an unreadable expression in his eyes, and he asked, "Are you trying to tell me...you have feelings for me, Liv?"

Olivia chugged back her second drink and waited until the barman poured her a third, drank half of that one and said, "No, El. I'm telling you I'm in love with you." She knocked back the rest of drink three, but before she could ask for a fourth, Elliot grabbed her hands.

"Slow down, Liv," he cried. "I really need you to be sober right now." Olivia looked at him and her eyes watered. His eyes were filled with emotion and he cupped her face in his hands. "Do you mean that?"

"Yeah," Olivia sighed, closing her eyes. "I shouldn't have said that. I just fucked up, badly, so could you forget I said that?" she asked, opening her eyes again.

"Liv," he said, turning her toward him on the bench, "Do you know how long I've waited for you to tell me that?" He smiled and pulled her face toward his, kissing her, trying to tell her he felt the same way. He pulled away from her and he saw how stunned she was.

Olivia looked up into his eyes again. "What the hell..."

"To tonight, Liv," was all he said. A toast. Then he picked up his beer, tapped her whiskey glass, and chugged.

Thirty minutes later they were laughing hysterically at the silliest stuff, like the ugly toupee the man next to them was wearing. They couldn't stop smiling, holding hands, and stealing sweet kisses. Elliot looked at her, half-drunk, and said, "Take a walk with me, baby!"

"Where, El?" Olivia asked. "It's two in the morning."

"It's Las Vegas," Elliot said. "I'm sure we can find something to do, right?" He chuckled, left a hundred bucks on the bar, and pulled Olivia up, into his arms, kissing her. "I should have done this years ago, Liv. Told you I loved you, ya know?" he laughed, pulling her out of the casino.

"Yeah," Olivia said, laughing, slightly intoxicated. "I know."

Olivia woke up first, the next morning, with a throbbing in her head and one between her legs. She rolled to the left and realized someone else was in her bed. Naked. She groaned in realization, knowing exactly who it was. "El," she whispered.

"Hmmm," he groaned, pulling her closer to him. "Munch and Fin are taking the first shift, we don't have to get up, yet, baby."

Olivia smirked. He must have remembered last night, too. There were some parts of the night, though, that were fuzzy. She remembered their fight, and she remembered going to the bar. But then she remembered taking his clothes off, him taking her clothes off, and being kissed, loved and worshipped by Elliot. But everything between her fifth drink and the mind-blowing sex was all a blur. She let her eyes drift open as she ran her fingers through his hair, and she met his open blue eyes.

"Good morning," Elliot said, smiling. He kissed her, deeply.

Olivia brushed his hair back and responding, "Good Morning. What do you remember about last night, exactly?"

Elliot smirked as he rubbed his head and tried to think. "You wore a short white dress, with these killer heels." Then he smiled. "You said that I was the only person you could see yourself marrying, because I was the only man you ever trusted, and ever loved," he recalled, brushing Olivia's hair back.

Olivia smiled, then, too. "That sounds like something I would say." Her brow furrowed, then, and she asked, "Did you tell me you were in love with me for the last seven years, and you stopped sleeping with Kathy because you were afraid you'd call her Olivia?"

Elliot laughed, heartily. "Well, that's true, so I guess I did."

"How long had it been?" Olivia asked, tilting her head, "And was last night enough to make up for it all?"

"I haven't touched Kathy in three years," Elliot said, shaking his head. He turned toward her and growled, "And God yes, Liv, last night was fucking phenomenal."

"What happens now, El?" Olivia asked, biting her bottom lip. "With us? With work?"

Elliot kissed her and said, "We are definitely gonna make this work, Liv. You're mine, baby, finally, and I'm yours," he said, laughing. "Unless, you don't want to. Unless you, uh, regret it. Do you?"

Olivia sighed, looked over at him, and said, "El, you just got divorced. We aren't even dating, and you know that we can't...we aren't allowed to..."

"So we won't tell anyone," Elliot said, raising an eyebrow. "We weren't dating before last night, Liv, but we are now. I think it's beyond dating, actually. I love you, with everything I have. I have for years, and I wanna make this work."

Olivia smiled at him. "Me, too, El," she admitted happilly, kissing him. "How do we keep this a secret?"

"Simple," Elliot said, "If anyone asks me, I say I'm dating this incredibly hot cop from another precinct, and you say the same thing, or we simply don't talk about our love life at work. We act like nothings changed."

Olivia laughed, kissed him, and nodded. "I love you, El."

"I love you, too, baby. You know," Elliot said, pulling her on top of him, "We should probably see what the sex is like when we're not slightly intoxicated."

"We so should," Olivia said, smirking seductively at him. She maneuvered herself onto him, guiding him into her, and she seethed. "Oh, God, Elliot!" she cried, throwing her head back in ecstasy as he filled her.

"You feel so fucking good, Liv," Elliot growled, reaching up to clutch her breasts in his hands, thumbing her nipples as she rode him. He bucked up into her, hard and deep and slow, and made this time last as long as he could. "Come here, baby," he whispered, tugging her down gently. He wrapped a hand around her neck, and the other around her waist, as he kissed her passionately and hit into her, pressing their bodies together as he slid in out of her in an incredibly slow, deep, hard rhythm. The moment they exploded, together, was the same moment Elliot's phone went off. Not moving Olivia off of him, or sliding out of her, he reached onto the nightstand and flipped it open.

"Stabler," he said, still softly kissing Olivia. "Yeah, we're on our way down." He snapped the phone shut and smirked. "Okay, Liv, it's time for us to act like a married couple and catch ourselves a bad guy."

Olivia kissed him, sliding off of him. "Two things that are very easy to do, as long as I'm with you." She dragged her hands down over his bare chest and that's when she yelped, "Holy shit!" She ran her right hand through her hair, as her left stayed frozen on his chest. "Oh, my God, El! What the fuck?"

Elliot saw what she was looking at, his eyes bugged out of his head, and he looked down at his own left hand. His old, dull, plain gold band had been replaced by a shiny, platinum, diamond cut one. He looked up at Olivia and swallowed back, hard. "Liv, baby, you don't think we..."

"Yeah," Olivia said, squeezing her eyes shut. "I do."

A/N: What happened? What happens with their case? Will they be able to keep this a secret? For how long? That's what you get for waking up in Vegas!
