When she makes her way through the narrow space of his Winnebago to his bed, careful not to wake him, she half expects to find him ready to unload his weapon on the intruder that used his spare key. Instead, she finds him asleep wearing nothing but his black boxer briefs, with his hand resting on his cock.

Olivia stands still and takes him in, looks at him with lust-filled eyes, as if it's the first time seeing his naked body, as if she hasn't known his form for almost 20 years.

Her eyes land on his hand that's now moving as he tugs a little on his cock while still asleep. She wants to put her mouth on the little butterfly tattoo on his upper thigh -among other things of course.

She reaches for the zipper on the back of her little black dress cursing silently when she struggles to pull it down and once she does, she slips out of it and then decides that she'll keep the bra and thong on in case he wants to take them off of her himself.

Only when Olivia sits on the chair at the end of his bed and opens her long legs and digs her black heels on the mattress near his feet, does she call his name.

"Elliot."

Elliot stirs, his muscles flexing. He recognizes her voice, sweet and low even half asleep.

His eyes open, trying to adjust in the darkness of the small space with the only source of lightning coming from outside.

"Elliot." Her voice is breathy this time and he moves sitting up a bit to see her. When he reaches to turn on the light, he groans at the sight before him. "God, Liv."

She looks like a dream. But she is something better. She is real. His reality.

Olivia is staring at him, her eyes dark, her lips parted. She is sitting in front of him with one side of her bra pulled down and her fingers playing with her nipple while her other hand is tugging her black thong upwards, the thin material almost hidden between the pink lips of her pussy.

"Don't touch yourself," she whispers, when he frees his cock from his underwear, ready to fist himself. He wants to protest but the need to give her what she wants is always stronger.

"Liv, what are you doing here?" His voice is low. His eyes go from her face to her tits to her pussy and he wishes he could focus on all three at once because he doesn't want to miss a thing from the magnificent vision that is Olivia Benson.

"I was careful, don't worry." Her eyes slip closed and for a moment she tilts her head back.

"Your boyfriend couldn't make you cum, baby?" He doesn't know why he can't stop being an asshole for a second, even when he has her naked in front of him, touching herself.

Or maybe he does know. It's the fact that he is jealous of Tucker for having a part of Olivia that she refuses to give to him. It's the fact that even though she comes to him time and time again she has to leave to preserve his cover. It's what she doesn't let him have of her that makes him die of jealousy. Her everyday life. And it's the same thing he can't give her yet.

She shoots him a dirty look and even though he knows what's best for him he can't help himself.

"Move the thong to the side," he instructs quietly, his eyes glued to her hand as she does what she's told.

He exhales looking at her, his hard cock twitches when he sees her glistening with arousal. He removes his boxer briefs then because the minute she tells him he can touch her he doesn't want to lose any time.

"Tell me why you're here, Olivia."

Her breath hitches when she touches her clit. She moves her fingers lightly over her folds, now coated with her arousal, and then back to her clit again.

"I was at the gala and people would talk to me and I couldn't even answer them because the only thing I could think of was your cock in my mouth."

He swears she'll kill him with the things she says to him. He groans and rubs a hand over his face.

She moans softly when she palms her tit and slips a finger inside herself but her eyes, hooded with desire for him, never leave his blue ones.

"Tell me how it feels, baby," he growls and she pushes a second finger inside curling them while pressing the heel of her palm against her clit.

"Nothing ever feels as good as you."

That's the only thing she'll give him, and she knows that when he thinks about it later he'll catch the double meaning but right now she doesn't give a damn.

He can see the flush on her chest and face and he thinks about how much he wants his mouth on her flesh.

She's picking up the pace, moving her hand faster and faster and he knows she won't be able to resist him much longer because he himself is trying his best to stay put.

"Liv, let me taste you," he growls at her when she removes her fingers from herself and puts them in her mouth.

"Come here," she whispers seductively as she slips her fingers once again into her pussy and picks up the pace.

He doesn't need to be told twice. He's on his feet in a second with his hard cock bobbing in front of her face.

He bends and grabs the back of her head and he crashes his lips to hers and before she knows it, his tongue is in her mouth. She can't keep up with his kiss and her lips fall open but he still doesn't let go of her, wanting to taste what she tasted.

His fingers fist her hair when she moans his name and her eyes close. He looks down at her face first- eyes closed and mouth open- and then his eyes drop between her legs to watch the way her curled fingers move inside her because he knows that's what she likes.

Elliot says her name then, "Olivia," and she opens her eyes and sees his desire for her and she fleetingly thinks at that moment how staggering this thing between them is.

He grabs her wrist and brings her hand to his lips and does what he's been dying to do since he saw her, tonight. He slips her fingers in his mouth and moans licking them and then he pushes her hand down and she slips her fingers inside her again.

He grabs his cock and tugs at it a few times and he brushes the head across her plump lips as his eyes follow the movement closely.

"Spit on it," his voice is husky and she does and watches as his hand moves and spreads her saliva and when he tells her, "Open your mouth," she feels her muscles clench at his words and when she smiles before opening -while looking at him- she thinks his eyes darken even move.

He pushes his cock in her hot mouth and her lips instantly wrap around it and he throws his head back and groans at the feeling but then looks down at her again before pushing even deeper.

"Is this why you came for, Sergeant?"

His cock falls from her mouth when she pulls back and smiles at him mischievously, "It's Lieutenant."

The pride he feels is mixed with his never-ending desire for when he says, "Wanted to celebrate with my cock in your mouth?"

She can only nod at him because his cock is in her mouth again, even deeper than before, and now he is pushing it against the back of her throat and she feels her eyes watering.

"Jesus, Liv," he mutters when he feels her hand clawing his ass, holding him in place.

He moves his left hand to take a hold of hers that's moving against her clit, with her two fingers still deep inside her, forcing her to pick up the pace, making her moan vibrate around his cock.

He feels the movements of her hand falter and his hips jerk and he is trying to control himself at the thought that she is so close to coming with his cock deep in her mouth.

Elliot pulls his cock from her mouth and bends down to catch her lips with his teeth and suck at them but she is so close that she doesn't react in time to kiss him back, and he's filling her again.

"Look at me, Liv," he says thickly, now both of his hands holding her face as she looks at him. "I want you to come with my cock in your mouth."

Her whimpers become louder and her thighs start trembling and it doesn't take long for her to come around her fingers and Elliot's hand is again at her wrist, keeping up her rhythm, "That's it, baby. Don't stop. Don't stop."

He can't take his eyes off of her face, flushed and beautiful and glowing as she has her eyes closed and he steps back to take a better look at her.

Olivia opens her eyes and looks at him and he pulls on her bicep helping her to stand up and her heels clank against the floor and Elliot pulls her close and leans his forehead against hers and rests his hands just above her ass, as her breaths hit his lips and her arms snake around his broad shoulders.

His mouth moves to her jaw and her neck as he places open-mouthed kisses along the way, his hands roaming her perfect body and coming to rest on her ass again.

"I thought you wanted to come in my mouth."

He feels his control slip away at her words and he groans in her ear, instinctively pulling her against him.

"Not this time, baby. This time I want to come in your pussy while staring at your perfect ass," he says and gives her a hard squeeze to emphasize.

Elliot moves and then he's fully behind her, and his fingers hook at the sides of her black thong and he pushes it down and it lands on the floor as she closes her legs to let it slide off.

His teeth bite at the flesh of her shoulder and he catches the strap of her bra between them and pulls it off and then moves his mouth on the other side and does the same, and then his fingers are unhooking her bra and when he feels it fall his hands slide at her sides and come up to cup her tits.

He squeezes them and then brushes his fingers across her nipples and feels them hardening against his touch and then he pulls at them with his thumb and forefinger and she sighs and her head falls back against his, and even though he can't see her, he knows that her eyes are closed and her teeth are biting her bottom lip.

He can feel her chest rising and falling with each breath she takes and his lips latch on the sensitive skin of her neck and he really wants to mark her but he knows she doesn't like it and he controls himself and lets go before he does and nuzzles her before moving his lips to her ear.

"Get on the bed."

She sighs again her hand coming up to caress the side of his face and he holds it for a moment with his own and then turns his head and kisses her palm. Olivia kneels on the bed and then lies down on her stomach. She props herself on her elbows and turns to look at him as she rests her head against her hands.

Elliot looks at her, and his dick twitches in excitement. He removes her heels slowly and takes his time to caress her feet and calves before keeling on the bed himself, hovering over her. He pushes her legs closed with his knees as he comes to straddle the back of her thighs.

He bends down and kisses her back and shoulders slowly and moves her hair to the side and this time he can't help himself and bites on the nape of her neck. Olivia's hips jerk against his cock and her hands are fisting the sheet and Elliot groans at the sensation and he can't wait anymore. He braces himself with one hand on the bed next to hers while the other is on his cock as he presses it against her ass and guides it down and then he feels the wetness of her and he pushes his hips forward and he is finally buried inside her.

Her breath hitches as she feels him slide all the way in, not giving her a chance to adjust. Her whimpers become louder as his thrusts became harder, his fingers grabbing her hip so hard he knows he might leave a mark. "Am I hurting you"?

"God, yes, don't stop," she whimpers again and he groans at hearing her words and moves his left hand and wraps it around her neck squeezing just enough while his right leaves her hip and fists her hair.

"Want me to make you cum?" Elliot's voice is thick as he speaks resting his chin above her ear and he hisses feeling her hand wrap around his wrist, not letting his hand move from around her throat.

"Yes," she stutters.

"Beg me, Lieutenant." His rank kink knows no bounds with this woman. He feels her thighs tremble and he knows she loves it as much as he does.

"El, please, please, please," she whimpers unabashedly, asking exactly what she wants, and he picks up his pace and starts pounding into her fast and hard, giving her exactly what she needs to come.

He almost comes himself when she starts shaking as she cums hard under him. He doesn't wait for her to stop as he moves and snakes his hand around her waist and lifts her still trembling body to stand on her knees.

He grabs a handful of her ass and squeezes hard, his fingers white and he looks down at his cock as it disappears inside her tight pussy. He is ready to come at that moment just as he wanted to, from the moment he saw her tonight -fucking her from behind - but he remembers how she came all the way to him in the middle of the night because she couldn't stop thinking about sucking his cock.

He lets go of her hips and pulls out quickly. "Turn around and open your mouth."

Olivia looks at him, her brown eyes full of lust, and just like before she smiles at him before opening her mouth. Elliot slips his cock inside while stroking it and cums with a loud grunt. She lets her hands rest on his strong thighs and keeps her eyes on him as his own close and his head falls back on his shoulders, his strong hand holding the side of her face as his hips jerk. When he stops coming and looks down at her he can't resist kissing her. Olivia grabs his face in her hands and pushes her tongue deep into his mouth letting him taste himself.

When she pulls back and falls on the bed he moves and lays next to her. "I thought you wanted to come inside me while staring at my ass," she teases him.

Elliot chuckles. "Yes, but I just love giving you what you want," he teases back and she laughs

"Shut up."

Her phone rings then and she moves to grab her purse and answer it. "Don't you ever turn that thing off?" he groans because he knows she will leave.

"Can't, we're short-staffed," she says as she answers it. "Benson, OK, I'm on my way."

He stares at her as she speaks and then moves to grab her clothes.

"Who were you at the gala with?" He tries to seem nonchalant and not at all jealous because he knows she hasn't disclosed her relationship with Tucker, yet.

She sees right through him but still answers without laughing. "My chief."

"You know he wants to fuck you."

She laughs, then and turns to him now fully clothed. "Elliot, you think everyone wants to fuck me. Now, zip me up."

"That's only because everyone does- because you're so fucking hot." She rolls her eyes at his words. Elliot stands on his knees on the bed and zips her dress and then turns her to face him.

"Be careful," he says and kisses her lips softly, "call me when you get to your car."

"I'm a big girl, Elliot, but I know you won't sleep till I do, so I will."

He smiles and lies on the bed again, and as he looks at her walk to the door says, "I'm proud of you," about her promotion. Olivia nods at him smiling and just as she opens the door to walk out she hears his voice again.

"Say hi to your boyfriend for me." She turns and glares at him but doesn't miss a beat as she throws back. "Say hi to your redhead."

He laughs then, as she locks the door behind her, and it's deep and loud.
