A few weeks earlier.

Olivia was up earlier than usual that morning. She didn't know what it was but she just couldn't stay asleep no matter how hard she tried so eventually she gave up and got out of bed deciding she could get some extra housework done before Noah needed breakfast.

It had only taken her unloading the dishwasher to realise that was a waste of her morning. When it was quiet she might as well spend a little extra time getting ready, after all she had someone who was paying close attention to her nowadays and it felt good.

She took her time moisturising after the shower, soaking every inch of her with lotion because she knew - or hoped - Velasco would be touching every inch of her later this evening. She'd put on a bit of extra eye make up, a little more eyeliner and a darker shade of lipstick and she'd taken a lot more time on her hair than usual, applying hairspray to make sure it was still in place for when he came over.

Choosing what to wear was a little harder. She'd started to ditch the oversized blazers but they still took up most of her wardrobe, even her slimmer ones just weren't giving the right vibe. Eventually, just as she was losing all hope she finds a dress she'd not worn since Amanda's daughters christening. It was tight and figure hugging but black enough to be work attire. Well, she'd worn it to the office before and got no comments. Why not? It was summer after all, a dress was totally acceptable.

She slips it off the hanger and over her head and admires herself in the mirror. Today she was going to have to be a real captain because there was no way she was chasing down perps in anything that went with this. A spare set of clothes was a given in her office anyway so as she slipped on a pair of black stilettos she smirked into the mirror knowing she had made good use of her morning to drive Velasco wild.

—

Velasco was already at his desk when he heard the elevator ding. Like an eager little puppy he turned around just waited for a glimpse of her only to be disappointed once again. He kicks himself internally at just how desperate he was to see her. She was his boss and this was wrong but it only made him want her more and lord did he want her.

"Cheer up. It might never happen." Fin says from across their desks not even looking up and Velasco knows he needs to up his poker face a little better. It wouldn't be long before Fin catches on to what's going on between him and their boss at this rate.

Before he could reply he heard the elevator ding again and spun around in his seat and this time he was rewarded, more than rewarded. His jaw almost hits the floor when he sees her step off the elevator and he curses the wall that covers most of her body as she walks the hallways to her office. He wants to stand and walk over to her but it would be too obvious if he runs to her the second she arrives so he waits patiently in his seat for her to get to the end of the hallway and prays she stops before entering her office.

"Hey Cap', you got a sec?"

Velasco could kiss Fin right now calling her over towards their desks. Olivia is avoiding looking at him he can tell as he so desperately tries to catch her eye. His mouth dries as he watches her cross the room to Fin desk in a dress that had a slit along her thigh and heels he knew would make her just the perfect height.

"Everything okay?" She asks Fin as she is within earshot and he nods his head at the screen.

"Nah. Look at this."

Olivia pulls her glasses out of her bag and leans over Fin's shoulder and Velasco wishes she had on a low cut top because he'd have a perfect view. As if reading his mind she finally looks at him over her glasses and she watches him shift in his chair, his hand reaching under the table to adjust himself and she holds back a smirk.

Velasaco doesn't take his eyes off Olivia as she chats to Fin, he was unbothered who notices him staring when she looks so good but she doesn't look back at him until she's standing back up and heading back to her office and she flashes him the smallest smile. Velasco watches her go with a grin on his face until eventually he hears Fin laugh.

"Put your tongue back in. she's old enough to be your mother!"

Velasco blushes and shuffles in his chair, embarrassed to have been caught but he knew his eyes weren't leaving that office window for the rest of the day.

--

She hoped it didn't look suspicious that she'd told everyone to go home early but she couldn't wait any longer. Every time she had left her office she could feel him watch her and she knew he wanted to devour every inch of her and she felt the heat wash over her body a little more throughout the day until she felt right on the edge with him.

There was always a little foreplay with them at work, a lingering gaze that felt so heated when nobody else knew the truth about them but today it was worse. She knew the second she invited him into her office she was throwing all of her rules out of the window. No fucking in the presinct. She had promised that to herself all of those years ago, determined not to be a cliche, especially when she had gotten her own private office but right now the drive home seemed like too much of a waste of time.

"Velasco, my office." There was nobody else left in the squadroom but still she spoke professionally and kept her face neutral until they were both behind the closed door and his hands were on her instantly.

"Fuck Liv.." he groans grabbing two handfuls of her ass as he nuzzles into her neck. She grabs his biceps for support and tries to hold back a groan as she tries to play hard to get.

"Captain Benson."

"Fuck Captain Benson.." he corrects himself abs she grins as he places small kisses along her neck, her arms wrapping around his. "You look…"

"I look?"

Velasco pulls back to look at her as he walks them back to her desk and doesn't stop until her legs hit the back of it and she pushes herself up to sit on the edge.

"So hot. So sexy."

"Yeah?"

His hands move from her hips to her thighs and slowly push up her dress as he speaks, his eyes dropping to watch the freeing of her thick thighs.

"I've been so hard all day, just picturing my face buried between your thighs."

Olivia groans as her legs instinctively open and his hand slides between them.

"Don't let me stop you."

Velasco looks back at Olivia and grins before dropping to his knees and opening her legs wider. He kisses up her thigh until he is close enough to reach out and taste her arousal before switching to the other leg and starting the trail again. Olivia groans in frustration, pushing her core towards the edge of the desk egging him on.

"You've made me wait all day Captain." he explains as he runs his tongue along the side of her underwear. "It's been torture, knowing you were in here just waiting for me to fill you up. Fuck, id have done it with them all out there."

She doesn't doubt it and it makes her smile that he's so desperate to fuck her he'd do it next to a room full of people.

"Don't you wanna see how wet I was for you all day too?" she tries, deciding to play him at his own game. "Just imagine how close I was to lifting up this dress and reaching my hand down into my- ohh." she doesn't get to finish her sentence before her underwear is pulled to the side and he's sucking on her clit.

"You always play so dirty Captain." He says when he pulls back to replace his lips with his tongue and Olivia half laughs, half moans in response.

Her hands grip into the edge of her desk, afraid if she moves them she'll fall right off but he knows what she likes and he brings her body right to the edge making sure to get her into the position she loves when she rides his face. Her breathing is getting louder and when he hears mutterings of fuckfuckfuck over and over he pulls back and her head snaps down.

"What the fuck?!"

Velasco pulls back to stand up and licks his lips.

"I've been waiting all day for this. I wanna feel you. Put them on."

She knows what he's on about without even asking and shakes her head as she feels behind her for her glasses, placing them on her face.

"Is this what you want, detective?" Velasco bites his lip at the sight before him as she raises her brow over her glasses with her legs still spread on the edge of her desk.

"Yes Captain."

"Then get over here."

Velasco steps forward and wraps his arms around her and she squeals as he lifts her up where she hadn't been expecting it.

"Im gunna fuck you right here." he says placing her down on her side of the desk and answering her silent question. "So that every time I walk in here I can think of this."

Olivia stares him down for a moment wondering if this was giving him too much power, it's hardly the image she wants him thinking of if she has to reprimand him but it doesn't take long for her to get on board.

"Then you better fuck me the right way." she says slipping off the desk and turning around, bending herself over the desk slightly.

"You're such a bag girl." he whispers into her ear as he bites down on her lobe and she grins.

"Maybe you can fuck it out of me."

"I plan to."

He yanks her underwear over her ass until they drop to the floor and as she steps out of them he starts to unbutton his jeans.

"I can't believe I'm doing this." Olivia turns around confused and he blushes realising he'd said his thought out loud. "Just living a lot of men's dreams right now." he clarifies and she smiles.

"Oh I know."

As if to show him what he was missing out on while wasting time talking she arches her now bare heat towards him and he grabs hold of her hips hungrily.

Velasco looks down between her legs and groans as he sees her arousal glisten on her pussy. He pushes his dick through her folds and she bucks back groaning as he finally touches her. Her hands cling to the edge of the desk in front of her as she looks back to him.

"Fuck me detective." Velasco pushes into her and they moan together as her walls tighten around him where she was edged just a moment ago. "Hard."

His grip on her hips tightens as he gives her what she had just demanded. Olivia's head falls forward and she tries to muffle the sounds of her moaning even though the sound of their bodies connecting echo's around the room.

"You feel so good." He tells her as he looks down to watch his length slide in and out of her. "And you look… fuck you look…". He struggles to find words to express how good she looks but she gets the picture. "Let me see you."

Olivia looks back at him and he grabs her by the chin pulling her whole body backwards so that he can kiss her. Her arm wraps around the back of his neck to hold him close as he fucks into her.

"More." He practically growls pulling out of her and spinning her around to sit her on the desk before she can process what is happening. "I need to see you come undone."

Olivia grabs his T-shirt and pulls him back in, her heels digging into his ass as he pushes himself back inside her.

"Oh god, don't stop." She warns as her head drops backwards when she sees he has no intention of stopping. He wants to see the look on her face as she comes over his cock more than he wants to breathe at that moment.

"I won't baby. Whatever you need."

Her eyes open and she drops her chin back down to watch him. She could see his muscles bulging through his T-shirt and he was practically holding her full weight in his arms yet still looking at her like she was the most amazing thing on this earth.

"That's it." He coaxed, he could tell she's close, he'd learnt her tell. "Cum for me, all over your desk. Every time you sit here I want you to think of this."

Her hand not on the desk wraps around his neck holding his head close as she kisses him. It was sloppy through their heavy breathing but it sent her over the edge. She lets out a moan against his lips as her walls tighten around his cock and he presses their lips together as he emptied himself inside her, Olivia holding onto the desk tight at the force of his last few thrusts.

Velasco kisses her softly as they catch their breaths, his dick still inside her until he feels himself softening and their cum start to run down his balls.

"I hope you're going to let me do that again." He asks, grinning at her.

"I think it's best you don't come into my office with other people around in case you get tempted."

Velasco grins and steps back, placing her legs on the floor before leaning down to pick up his jeans.

"Just don't keep your glasses on and we might be okay."

Olivia smiles and looks over the top of her glasses at him.

"Why is that detective?"

"Captain." He says with a warning tone taking a step forward again. "I think I've still got some work to do with you."

"Mmm. I think so too."
