AN. Please note this is benlasco with Elliot as the voyeur. I still decided to add as it is sort of EO and I know a lot do read my benlasco fics but you have been wanted if you want to skip this chapter.

"Take him out of here. We're done."

Fin nods and cuffs the perp that was sitting on the other side of the table before dragging him out of interrogation. It was getting late and he wanted to get home so he was thankful that Liv had given up interrogating him, it was clear to him that they were getting nowhere and maybe a night in lock up would get them somewhere.

He nods to Velasco on the way out who was waiting outside the door and wonders why he hadn't clocked out already but he wasn't going to sit around wasting his own time asking.

"Need any help?"

Olivia jumps at the sound of the man's voice behind her until her brain registers whose voice it is and she smiles as she files the paperwork she'd spread across the table back in the correct order.

"What are you still doing here?"

She keeps her back to him as she speaks and he closes the door behind him and walks over to his Captain who was still filing papers instead of looking up at him.

"I forgot to do something."

"Yeah?"

"Say goodnight."

"You stayed for that? After everyone else had gone?"

He knew she was checking they were alone and he smiled.

"You know I love the perks of being last here with you."

Olivia finishes tidying up the papers and throws them down on the chair she had just been sitting in knowing if she put them on the table they'd be thrown around the room any second now.

"What perks are those Detective?"

"This is a new one." He grabs her hips and pulls her so they're both facing her office before pulling her ass into his growing erection as he looks up to the window in front of them. "You ever look through that window in your office and think about getting fucked on this table?"

"There have been times when you've looked pretty good in here…" she answers honestly and he grins, pulling her hair off her shoulder and leaning in to kiss her neck.

"When I watch you interrogate a perp I get so hard. Just thinking of bending you over this table and knowing we can watch ourselves in the mirror."

Olivia's hand snakes behind her and between their bodies to cup his cock in her hand and starts to stroke over his jeans.

"Then what are you waiting for?"

--

Stabler had just left Amanda at the hospital and she had not so subtly told him how Olivia was working late tonight as they had both headed home so he had decided to pop by and see if she fancied grabbing a bite to eat or a beer. She wasn't letting him into her life with her son but he was hoping if he asked her out often enough just the two of them she'd cave eventually.

He sees Fin heading out on his way in and stops to say hello.

"She in her office?" He checks as Fin moves to head off and the other man nods.

"Yeah she should be. Just go and wait for her."

Elliot nods goodbye to his friend and walks towards the Captains office where the door was closed. He knocked but had no response and when he heard no voices inside he opened the door just enough to push his head in. Finding the room empty he decides to do as Fin had suggested and wait, she shouldn't be much longer if Fin was on his way out.

He walks into the room and the light still on in interrogation catches his eye and he realises Olivia might be a bit longer than he had expected as she was currently bent over the table being fucked into from behind from one of her detectives.

Elliot is frozen in place, his mouth falling open as he sees the love of his life being ploughed by another man. Her eyes look straight at him but nothing in her demeanour changes and he wonders if she knows he is there.

"That's it Liv. look at yourself, you look so fucking good." He hears the younger man say and then he understands why she is looking at him so intently, she's watching the same thing as him - another man fuck her.

He wants to go in there and punch the other man until his face is a mess but a conflicting feeling in his pants is keeping him frozen to the spot. The look of pleasure of Livs face is more enticing than any violence towards the young detective and he feels the straining of his pants begin. His hand falls to his cock, stroking it through his work pants as he tries to relieve some of the pressure he is feeling. He wonders for a moment what she'd do if he walked in there and joined them, would she let him? But the fear of being rejected keeps him in her office watching.

He could tell from the way she gripped onto the edge of the table and moaned that this wasn't their first time, whatever Velasco was doing with his hands it was what she wanted. He noticed it first up her shirt and he felt hot with anger at another man getting to hold the tits he dreamt of for twenty years and then his hand had moved out of sight and from the biting back of her moans that she was doing, Elliot imagined it was to her clit.

Elliot watches the roll of her eyes and knows she is close. Out of curiosity his eyes fall to Velasco who he can tell is struggling to hold back and is surprised to find himself thanking the young man for having the courtesy to hold off and wait for Olivia.

"I'm almost there." He warns and Elliot curses him. If he doesn't get to see the look on Olivias face as she comes then he really will go in there and hit him.

"Almost there baby, don't stop."

Baby. That word makes his blood run cold and he wants to punch the glass but instead he places his hand on it and cups his cock harder, trying to calm himself so that he can relive the sight in front of him when he is alone and can cum calling her name.

"Oh fuck Liv." Velasco groans and Olivia moans right after him.

"There, yes. Fuck right there."

Elliot sees the second she starts to cum around another man's cock and he lets out his own silent moan as he watches her mouth fall open and her eyes fall shut. The sound leaving her mouth is the most beautiful sound he's ever heard and it takes all his strength not to close his own eyes and let his hand bring him to orgasm with her but he reminds himself to watch, to remember.

He doesn't blink until she slumps down on the table in front of her and the man behind her takes a step back and Elliot watches the way he is looking at her pussy and smiling. He knows then that she didn't even make this guy wear a condom and he wonders how long she's been fucking her detective, it seems like its serious. Is this why she keeps him at arm's length? His anger is back now and he wants to walk in there but admitting he had stood around and watched that scene to them both didn't sound appealing so he waited.

He watched as she kissed another man goodbye, watched as she pulled up her panties full of another man's cum and came walking towards her office as the detective took the other door.

Olivia jumps when she sees Elliot standing next to the glass facing the door she was coming out of. From the look on his face he'd seen enough for her to be in trouble.

"What are you doing here?"

"Rollins said you were working late, I thought I'd see if you fancied doing something but it seems I'm a little late to the party."

"Whatever you think Elliot, it isn't really your business is it?"

She tries to sound brave but inside she was a mess. She knew she was free to do as she pleased but whatever she and Elliot had was complicated and she wasn't sure she wanted him knowing about her sexual partners, especially not ones she worked with.

"Isn't it?"

Her eyes fall to his cock which she now notices is still bulging against his trousers even though they were almost rowing and she grins.

"You know Elliot.." She starts much calmer than she had previously sounded. "If you wanted to join us, you only had to knock."
