A/N: Okay, so, we don't know that she is going to actually be his supervisor, just a fun little fantasy. I think it will just be a one shot.

Olivia was going to be his…boss?

Elliot shifted uncomfortably against the thin mattress on one of the bottom bunks in the crib. Yes, he had been pissed off at the news at first, seeing that he had rank over her, but when he was reminded of his various run ins with IAB and blemishes in his jacket, any fight he had had left him. And the more he'd thought about it, the happier he became for Olivia, knowing that she would do a great job even though this would take some adjustment for everyone.

He sighed and closed his eyes as he thought back to Captain Cragen's retirement party last week. He shifted again, the bed creaking with his weight as he pictured Olivia, her hips swaying to the soft rhythm as she danced with Cassidy, who had returned to wish Cragen a final farewell. He'd also returned, apparently, to follow Olivia around like a love sick puppy. Elliot had watched as the two laughed as they moved together, his blood pressure rising from both the pang of jealousy he felt and the way Olivia's royal blue dress clung to her body. He'd taken a long pull from his beer bottle and nearly crushed the glass in his hand as Cassidy's hand wandered to rest at the curve right at the top of her ass.

Elliot now groaned as he felt his groin tighten at the memory of what had happened next. He'd cut in on the two and pulled Olivia flush to his body, reveling in her heat, her softeness and scent. He'd wanted to feel her like that against him skin to skin, no barriers, buried deep inside of her. He'd wanted to pull her off into a dark corner and slide his fingers into her wet heat until she writhed against his hand and moaned his name.

But she was his boss now. He needed to erase the fantasies he'd been having about her for years and begin to see her as his superior. An authority. The woman in charge of him. Above him. That owned him…

Fuck, this train of thought would lead nowhere good.

He snaked his hand down below the scratchy precinct blanket, unbuttoning and unzipping his pants, groaning with frustration as he pressed his open palm on his forming erection over his boxer-briefs.

He imagined Olivia, dressed in a black lace bra with matching boy shorts and leather lace up high heeled boots that went up to her knees. Nothing else. She'd call him into Cragen's office…her new office to discipline him.

Elliot released a long shaky breath, slid into his boxer briefs and gripped his solid length. "Shit," he whispered into the dark, empty room, inhaling deeply and refastening his pants, groaning as he stood and headed for the men's room. As much as he wanted to, he couldn't do this in the crib where anyone could just walk in.

He entered the last stall and quickly undid his pants again, pulling out his semi erect dick with one hand, while the other was pressed palm out against the wall in front of him. He stroked himself slowly as he closed his eyes tightly and bit his lip.

He knew that Olivia was downstairs moving her things into her new office. He imagined her in the same get up as before, bra, panties, boots, this time bent over her desk as she organized her drawers. He'd walk in and close the door behind him and she grin at him over her shoulder.

"Sit down, Detective," she'd say as she straightened to her full height, dangling handcuffs from her fingers.

He'd sit as she'd strut over to him and lean forward, her lips practically brushing against his, her soft hair tickling his face. "Liv-" he'd grit out.

"Liv?" she'd say against his lips. "It's Captain to you now and you need to be punished for that shit you just pulled in interrogation." She'd straighten her body and pace the office, the heels of her boots clicking against the hardwood floor.

Elliot grunted as he massaged the tip of his dick with his thumb as he imagined what would come next. His heart raced and his breaths quickened.

"Now, do you need me to cuff you or will you accept your punishment, Stabler?"

"Punish me," he'd pant, his eyes drinking in her voluptuous curves as she'd drop the cuffs and straddle his lap.

"Think you can handle it? It is the only way to avoid another write up in your jacket." She'd tease, smirking that sexy little smirk she always gave him when she knew she was right or up to no good.

"I can handle anything you've got, Benson."

She'd roll her hips against him and lean back to remove her bra, exposing her perfect breasts. "Touch me," she'd breathe.

"Fuck." Elliot would lean forward and trace his tongue around each nipple before closing his lips around one to suck roughly, and then bite down gently. He'd make her moan for him and she'd love every minute of it.

He sighed softly as he tightened his grip, squeezing and stroking himself roughly now. He could barely stand straight as he pictured Olivia halting his actions to stand before him, stance wide.

"Get on your knees, Elliot."

He'd only do this for her. Only her.

He'd slide down onto his knees only inches from the front of her panties, her heat and scent radiating.

"Take them off."

He'd swallow harshly and slide the panties down her long legs slowly, over her boots and bunch them in his hand, bringing them to his nose to inhale deeply. He'd shove them in his pocket as she'd throw one leg over his shoulder, the heel of her boot digging into the back of his shoulder.

"Now take your punishment, Detective, and make me come."

"If this is punishment, I'll make sure to get in hot water with you every day." He'd slide his hands over her boots and up the smooth skin of her thighs, stopping to grip her ass and breathe hotly onto her wet center.

Her voice would falter. He knew it would. He'd bring her to her knees and show her that she wasn't the only one in charge. Not of this.

He'd lick and nip at the inside of her thighs as she'd dig her heel in deeper, causing exquisite pain until he complied with her request.

She'd finally not be able to take any more of his teasing and grind herself onto his mouth as he licked and sucked her with fervor, forcing his tongue and lips against her, around her, inside her. She'd moan and scream his name and come against his waiting mouth and…

"Oh, God, Liv!" Elliot's cries echoed into the empty bathroom as his release took over his body in powerful waves. He then leaned back, practically collapsing against the stall door as he tried to slow his breathing.

A soft knock at the door startled him from his reverie and he immediately zipped his pants and left the stall to wash his hands. "Be right out," he called to the intruder.

"It's Olivia…just wanted to say good night and I couldn't find you anywhere. You okay?"

Fuck. How much had she heard? He knew he hadn't been that quiet and God knows what he must have muttered during his fantasies.

"Yeah, I'm okay, Liv. I'll be out in a minute." He hoped his shaking voice didn't betray him.

"All right, but as my first order as new Captain, I insist you go home for the night and get some rest. You don't want me to have to write you up for insubordination, do you?" She teased. "Night, Detective Stabler."

Elliot groaned and scrubbed a hand down his face as he heard her footsteps retreat down the hallway. "You can order me around anytime, Benson," he muttered under his breath before splashing cold water on his face.

This was going to be one hell of a transition.

Should I keep this as is, or continue with more of Elliot and Olivia's fantasies regarding her being his boss? I have more ideas, but I'm not sure if I should just stop here. Any thoughts?
