A/N: Hope you guys enjoyed last chapter! Let me know what you think if you've got the time, and again, sorry the long wait for these last two chapters.

CHAPTER TWENTY-FOUR: BEING FRISKY IS PRETTY RISKY…

"Liv had to go see Barba about something, but she said you'd be coming by and could go into her office to wait for her." Nick spoke when Elliot appeared in the bullpen one afternoon.

Elliot smiled and nodded, "Okay, got any idea when she'll be back?"

"Not sure actually. Can't imagine she'd be long though." Nick replied.

"Sounds good. So ugh, I guess I'll be in her office.." Elliot hadn't felt so awkward in his life. Everyone nodded, and he made his way to her office. He loved coming in her office, it was still like Don's office, though she obviously added her own touches, most notably a lot more lighting and pictures than Don ever came close to. She had two of her and Noah, one of John, Don, Fin, him, and her, another of what looked like the squad now, a few of just Noah, quite a few of them that the two of them had taken over the past month and a half, and even one of her at her sergeants promotion ceremony. He smirked thinking that he'd get to see her in person the next time she got to put it on. Elliot shifted his jeans slightly, seeing Olivia in her dress uniform was something to behold, and frankly it turned him on.

He walked over and shut her blinds, on both her door and the one that blocked out the bullpen. Then he decided to go over to her small couch and lay down, to generally make it seem like no one was in her office. He put one arm over his eyes, the other across his stomach, and unintentionally fell asleep.

About half an hour later, Olivia walked back into the bullpen. She looked around, but didn't see Elliot. She didn't even notice her blinds were shut. She furrowed a brow and walked over to Nick and Amanda's desks, "Hey Nick, where's Elliot?"

"He went in your office about half an hour ago." he replied without looking up, "When he came up I went over and told him that you had to go see Barba, and that I didn't think you'd be too long. I swear he was in there, because he was looking at all your pictures last I saw of him…" Nick finally looked up, then turned around towards her office, but saw what Olivia saw: nothing.

"I'm going to go look in my office." Olivia declared, and walked towards her door. She finally noticed the blinds were closed, so she quietly proceeded. She opened her door and looked into her office, and there he was, fast asleep on her couch. She smiled, took out her phone and took a quick picture. After she put her phone back in her pocket, she turned around to see Nick, Amanda, Carisi, and especially Fin watching her. Fin had apologized and begrudgingly taken the few days off about a month and a half ago now, but he still seemed generally peeved at the who situation of her choice to allow Elliot back in so quickly. She gave them a thumbs up that he was in there, everybody nodded and went back to whatever they were doing.

She slipped through her door, quietly shut the door and locked it behind her. Elliot stirred in his sleep, and Olivia stopped her movements including her breathing until she saw that he was still asleep. She couldn't help but smirk to herself, he was in a for a shock of his life, but before that she had to have a little fun with this first. She took off her high heels to prevent them from waking him up when she walked over to the couch. As soon as the offending shoes were off, she tip toed over to him, and sat in front of him. Without touching him, and trying not to even breathe on him, she acted like she was going to kiss his cheek and took a picture. She felt like a teenager, but frankly didn't care.

After slipping her phone on her desk, she purposefully unbuttoned all but the middle button on her blouse she was wearing that particular day. Underneath the black blouse was the cherry red lace front clasping bra he had gotten her for their one month anniversary. She had been entirely blindsided that he was into the small anniversaries and so she hadn't gotten him anything, but he told her that just her being with him was enough to last every anniversary they would ever have.

Even so, it wasn't an every day occurrence she wore something like this to work, but she felt like wearing it today and now she was more than happy that she had. After walking closer to where he was, she carefully took her belt off. Olivia was shaking slightly, with the ever present possibility her squad would need her for something a real one, the thrill was definitely worth it though. It kind of scared her how much she was enjoying this already, and she hadn't even touched him yet.

She bent down and started to kiss his lips ever so lightly. She could feel him start to wake up as she increased the pressure on his lips, and enhanced the speed.

"Mmmm, Liv. You're at work, in your office." he groaned out against her lips, pulling back a little.

"Exactly. This is my office. Doors are locked, blinds are closed." she said back.

"In that case, don't stop Sergeant Benson." he grinned and grabbed her around the waist. He tugged and she fell on top of him, the two still lip-locked. She moaned into his mouth and that was practically all he could take. He sat up with her, still wrapped in his arms, to where she was now straddling him while his feet were on the floor. He detached his lips from hers and started kissing along her jaw line, down her neck, and eventually to her bra cover breast. Noticing it was the front clasping bra he had gotten her, he quickly unclasped it. He greedily put his mouth on her right breast as soon as it came into full view for him. At about the same time the chilly air around had instantly produced goose bumps all over her body. Both of Olivia's nipples were hard as pebbles now as he leaned her down on the same couch he was just napping on.

"Hmmmnn, El.." she moaned out a bit louder than the one from earlier, "Don't stop. Oh God, please don't stop." her breathes were now coming out more as pants.

"Didn't plan to baby." he whispered to her, taking a brief break of sucking on her breast and before switching he kept his voice low, and declared, "But you really gotta be a little more quiet, I don't think your squad wants to here you moaning or any other sexual noises." he chuckled.

"Fuck 'em, just have your way with me." she panted out.

"You said it, not me." he smirked, then unbuttoned the last button on her blouse. He proceeded down to her pants, unbuttoned and unzipped them too. "You're so beautiful Liv." he breathed her in as he slid down her pants and underwear together. He grinned when he realized she had already taken off her shoes, so her pants and underwear had come off quickly. She still had her blouse and bra on, but they were unbuttoned and unclasped. He sat up quickly as he unbuttoned his own dress shirt, took off his belt, unfastened his own button, and unzipped his jeans. Before he had the chance to do much else, Olivia pulled him down by his shirt. So now he had one hand on the back of the couch, the other one on the cushion, and his legs on the outside of hers.

She grinned as she used her hands to push his jeans down just far enough to release his hardened member. She chuckled lightly, "I guess it's true for you then, you're naturally aroused when you wake up."

"Oh no sweetheart, this is from being around you, and seeing that picture of you in your sergeants uniform." he smirked, then bent down and started kissing her again. "Ready for me baby?" he spoke against her lips. She nodded. He used his left hand to guide himself to her entrance, and slowly pushed into her.

"Ughh, Elll.." she moaned as he continued sinking down onto her, "Fuck.." she breathed out when he was all the way in.

"Such a dirty mouth Sergeant Benson." Elliot smirked.

"If you want to see a dirty mouth Mr. Stabler, I'll be glad to show you one if you don't move." she growled.

"Did anyone ever tell you that you are incredibly sexy when you're pissed off?" he couldn't help but have a little fun with her.

"Elliot I swear, move. NOW. If you don't you will find yourself on the floor and walking home." she growled again.

"Okay, okay." he grinned again, but pulled out slightly, then pushed back in with some force. "What do you want baby? Tell me." he ground out.

"You're a son a bitch, you know what I want. Let's go, we don't have a ton of time you know." she panted out as he picked up his pace and force behind each thrust. A few minutes later, he stopped.

Olivia looked up at him, "Wh- What are you doing?"

"Can we ugh.. Can we fulfill a little fantasy I've had forever?" he looked at her, then looked to her desk, back to her again. "Please?" he smiled sweetly at her.

She started laughing, "The work fantasy every woman dreams of and I'm not even the one that has to ask to do it? Now you are definitely not going anywhere, you. Are. Mine. Got that?" she smiled at him.

"Always have been yours Liv." he smiled back, but had a serious undertone to it. Before she had the chance to say or do anything else, he lifted her up -still inside of her-, and carried her over to her desk before setting her down on the left edge, and not- so carefully moved her picture frames and keyboard. Then leaned back over to where he had set her, picked her up again, and centered her on her desk. "Ready?"

"More than you'll ever know." she whispered as she leaned up and started kissing him.

With one arm he held her hip, the other was behind her neck keeping their faces as close as could be until he decided to tilt his head down slightly and placed light kisses along her jaw and neck.

About thirty minutes later, and many moans and many more expletives later, Olivia was lazily laying back on her desk, while Elliot picked up her underwear and pants.

"You going to ugh get redressed in case your squad needs you beautiful?" he laughed.

"Ughh..." she moaned, "I don't know if I can even walk right now.. But I suppose I should put my pants back on. You think you could do me a favor and get them started up my legs so I don't have to bend over too much?" she lifted her head to look at him. He was just watching her with a smile and amused look on his face.

"What about your panties youngin'?"

"Leave em off." she waved her hand at him, "It'll be easier tonight." she used as her defense when he had an eyebrow raised at her. He nodded with a wide grin on his face. The next five minutes were spent with Elliot redressing Olivia practically. The only thing she did was re-clasped her bra in the front. When she finished that, Elliot buttoned up her blouse kissing her stomach or chest with each button he came across. He had yet to button up his own dress shirt, but had pulled up his briefs and jeans as soon as they were finished. He walked over to the door and unlocked it, just in case her squad needed something urgent.

"I love you so much, and not just because you just risked your job, or that you fulfilled one of my multiple at work fantasies I once had, and still have -even if I don't work with you anymore-, but because you are the greatest woman I know. There are so many things that I love about you.." he pulled her off her desk by her hand after she had finally decided to sit up, and started dancing with her like they had waiting for their names to be called for lunch that first day when everyone -but Fin- had met Elliot, and his kids.

"I love you too, El." she whispered into his ear, as she pulled back, he grabbed her again and gave her a quick kiss, but she wanted even more. As she quickly deepened it, neither hearing the knocks on the door.

Rafael furrowed a brow, Nick had said that Olivia had went into her office about thirty- five minutes prior to see what Elliot was doing.. He knocked again, a bit harder, then walked in when no one answered. Once opening the door, he closed his eyes, shook his head, walked in quickly, and slammed the door shut, unintentionally, but sort of on purpose. The slamming of a door broke Olivia and Elliot apart from their lip lock, that was quickly about to go farther on behalf of Olivia.

"You two are so lucky it was just me. I'm surprised you aren't pregnant yet Sergeant.. Anyhow.. I'll pretend I didn't see that again, but if I DO see it again, it's going to be a different story. Do I even want to ask why your shirt is unbuttoned Stabler?" the ADA asked after turning back around from shutting the door. Elliot and Olivia looked at each other, Liv blushed, furrowed her own brow and asked,

"Wait.. Barba what do you mean that you'll pretend you didn't see that again…?"

"Oh nothing, I just don't want to see that at all.." Rafael internally smacked himself, now was definitely not the time to bring up what he saw when the two of them first got together as 'life partners', but covered well. "Now anyway, I just wanted to give you this: Your warrant for the perp's apartment in Brooklyn."

"Why are we getting stuck with this?! I thought Fin had called Brooklyn's SVU as soon as he noticed it was her?" Olivia asked as reached over to grab the pieces of paper Rafael was holding out to her.

"If you're talking about Kathy's little stunt that same day I met everyone that's new here, I already know about it." Elliot inserted.

"Okay, now it's my turn to say it: Wait, how do you know about it? It happened a month and a half ago.." Rafael looked at his friend, and Olivia looked at him shocked, he hadn't said anything, her and Elliot had talked briefly about what Fin and him had spoken about on the roof that night as the two of them were in Lucy's car, driving back to Olivia's apartment.

~FLASHBACK~

Fin's bruised jaw and Elliot's black eye did most of the explaining for her, but Olivia decided to ask anyway as she pulled up to the first red light, "Elliot, I want you to be completely honest with me when I ask you this question.. Okay?"

"You want to know how I got my nasty shiner, and what Fin and I discussed on the roof don't you?" he smirked looking over to her with his one good eye.

She let out a breath, "Is it that obvious that I want to know?"

Elliot shook his head, "Not to the average person, but to me? Very much so. I've known you for a long time Liv, and it's fine.. We'll talk about the stuff later, but as for my shiner, I walked up behind Fin and apparently scared him, so he hit me. My first reaction was to hit back, which is why he has a bruised jaw." he chuckled, "Uhm, as far what we talked about.. Mostly that I didn't give a damn if he liked what we have now, for your benefit I wanted him to at least respect you enough to keep the trouble to a minimum. He asked me why I hadn't talked to you about my own Demons as it was so obvious that you had told me about your own.. Which is what we'll talk about later. I love you so much Olivia, and please, please, please, don't feel like you can't approach me about anything. They may be hard to talk about, but that is what makes strong relationships stronger. I want our relationship to be the strongest of all time. So we can set a great example for my kids, for Noah, for each other." he grabbed her hand and kissed his way up her arm, and gave her a quick kiss on the lips before pulling back and mentioning the light had just turned green. They both laughed about it.

"You sir, are a tease!" she finally was able to breathe out after she stopped laughing.

"But I am your tease madam and you love me." he grinned back at her.

"Getting a little cocky are we? Already? Damn Stabler, we haven't really had our first alone date yet." she said with as much of a straight face she could muster.. She glanced at him with the corner of her eyes, and had to bite her bottom lip to keep herself from laughing at him. He was looking at her, apparently unsure of what to say.

"What's the matter El? Cat got your tongue?" she grinned.

He gave her an intimate grin back, and finally said, "Oh, there will be a cat -of sorts- that will have my tongue later tonight. And something tells me, I have every right to be pretty cocky right now." he took her hand that was resting on the gear shift, and placed it on his groin. She couldn't hold in the moan that escaped her lips then. She looked over at him quickly before looking back at the road in front of her.

"Jesus Elliot! Do you make everything I say sexual in your head?"

"No. Just being around you this close makes everything you say become sexual in my sexual regions, not necessarily in my head. Are you beginning to see why I tried not to get up very much when we were work partners? If you wouldn't have noticed it, I'm certain that John or Fin, hell even Don, probably would've called me out on it." he grinned at her.

She smiled as she pulled into her parking spot. She saw her SUV where Lucy usually parked. She put Lucy's car in park, and turned it off, but before either of them got out, Olivia turned to Elliot.

"El, hold on a second before we go upstairs.. I just want to tell you a few things. One, I can't wait to be able to be a great example for all of us, but especially to the kids. Two, I DO love you. More than you'll ever know. Three, no matter what Fin says, you will be hear to stay. And lastly.. I can't wait till tonight. When everyone goes to sleep. You are in for a treat." she leaned over, kissed his cheek, then went to his ear, and suckled on it's tip. It was one of the things she learned very quickly that made him absolutely bat-shit crazy. As she pulled back, he had his eyes closed, and was trying to regulate his breathing. "Come on big boy, the sooner we get upstairs, the faster everyone goes to sleep." she smirked as she opened the car door.

She heard him mutter, "And she says I'm the tease?" under his breath,

"I heard that! I won't let you have any if you keep being a bad boy!" she laughed, and heard him laugh with her as he jogged up to get the door for her, and kissed her cheek as she went by him.

~BACK TO PRESENT~

"Olivia… Olll-Liivvv-iiiaaa! You in there beautiful?" Elliot waved his hand in front of her face and snapped his fingers, slightly concerned.

"Huh? What?!" she shook her head of the brief flashback.

"You okay sweetheart? I was just telling Raf that yeah, I knew about Kathy's run in with Fin and Nick… Fin might've said something about that's how he initially found out I was overseas.." Elliot re- explained.

"Yeah.." she didn't sound entirely with it, "I ugh, I was just thinking back on our car ride back to my apartment on that day." she looked at Elliot who was grinning, but didn't say anything.. She had to bite her own lip not to say -or do- anything.

Rafael looked between the two.. "Okay, anyhow… since you know who we are talking about, we can talk about this openly. After you-" he was cut off by Elliot,

"Raf, can you let me make sure she's okay for like five minutes..?" Elliot asked his friend.

"Ugh..." the ADA wasn't sure what to say, thankfully Olivia saved him the trouble of trying to come up with something, when she spoke up,

"No, I'm fine El." she smirked, "Go on Rafael, I'm sorry for disrupting you."

The ADA nodded carefully, then started speaking again. "As I was saying… After you came by an hour and a half ago, apparently the ADA and one of his judge buddies in Brooklyn decided that since Elliot doesn't work here anymore, it'd be perfectly fine for us to handle it." Rafael rolled his eyes.

"Couldn't you both technically recuse yourselves given the two of you know her through me..? Well, at least for Olivia. And you knew her eons ago Rafael. And I'm dating Olivia, so that would still be a conflict of interest." Elliot elaborated aloud, looking between the two.

"Technically yes, but since this is completely unrelated to anything to do with you, especially since you and her have been divorced for nearly four years. Liv hasn't seen her in nearly just as long right?" Barba looked to the sergeant, and she nodded her head, "So, honestly, it could help Kathy if we did recuse ourselves. Will this be uncomfortable for all three of us? Particularly you two.. Yes. Very much so. But if we pawn this off to anyone else, it'd be much worse. You both would probably have to take the stand, Elliot, you will probably have to either way, but if you wanted, I'll call you up for our side. Does Kathy know you're back in the States?" he looked to Elliot.

He shook his head, "Not that I know of."

In turn, Rafael nodded, "Good. We'll plan to go ahead with this on time then. We'll have the element of surprise on our side. For some weird reason, you want to go see her, she's in Rikers Elliot. Olivia, I would actually like you to go down to see her, just don't say a peep that you and lover boy over here" pointing to Elliot, "are dating, or anything. Actually, take Carisi with you, but tell him- Wait hold on a second, I'll tell you both how I would like this to work." he walked over to her office door, opened it, and called out to Carisi to make his way to Olivia's office. When he turned around, Olivia was sitting up on her desk with Elliot between her legs, buttoning up Elliot's shirt. With each one, she whispered something very quietly to Elliot, who just kept smiling and nodding.

"Do you two ever get sick of each other? It's been a month and a half, and the only time I see either of you apart is usually here in this office, but since Elliot obviously was here visiting you Olivia, I guess I should get used to seeing you two joined at the pelvis." Rafael commented.

"No." they both answered on whether they ever got tired of each other, and both laughed and kissed quickly before Elliot turned around guarding Olivia unintentionally, who then put her chin on his shoulder, and put her arms around him. There was a light knock on the door, then the door opened to reveal Carisi.

"You wanted me Barba?" Carisi asked as he walked in.
