Substitute

A/N: I think this story is missing one of those chapters. So here it is!

Warning: This is a real warning this time. This chapter is just a little bit spicy...

The day at work seemed to drag on, at least, it did for Lincoln and Olivia who were more interested in the evening. Honestly, where was a Fringe Event when one was wanted? Finally, after the boring day ended, the people who could began to pack up and go home. Olivia was one such person, closing her computer down and getting her things. Charlie leaned back against his chair, watching her with a raised eyebrow. Lincoln had been practically humming today and now Olivia looked...

"What's with you?" Charlie questioned her.

"Hm? What?" Olivia looked up.

"Any special reason why you're in such a good mood?" He asked curiously. Olivia merely smiled. "Come on, what's up? This has something to do with Lincoln, doesn't it?" he said, spot on.

"He made a reservation for us at a restaurant at Pimlico," she told him. Pimlico was the place where they had the fanciest, nicest places.

"Is that so?" Charlie grinned. "Well, 'hope you two have a good time."

"Thanks Charlie, we will!" Olivia grinned back. Olivia glanced up in Lincoln's office, seeing him furiously working on his computer, probably trying to wrap things up quickly. He was so focused he hadn't noticed her walk over and stand at his door. "Linc," she said, making her presence known.

"Oh, hey 'Liv," Lincoln smiled up at her, always happy to see her.

"I'll see you tonight, I'm gunna head home," she told him.

"Alright, see you soon," he nodded. Olivia glanced around, making sure they weren't being watched, and went to lean over his desk, kissing his cheek.

"Hey, you shaved?" She raised an eyebrow. He must have cleaned up when he got back to work that morning.

"Yep," he smiled.

"Aww, I kinda liked that fuzzy beard thing you had going on..." she grinned. While it tickled her when they kissed, she couldn't deny he looked roguish and sexy with it as well... though he still did with or without it anyway, it gave him that just-woke-up look, especially with his short, messy hair.

"Oh? Well then I'll hide my razor somewhere," he liked pleasing her, so he would go through the pains of keeping his little shadow trimmed for her. The things you do for love.

"See you later," Olivia smiled, shaking her head in amusement as she left. It was about an hour later when Lincoln showed up at the door, dressed to kill. "You look sharp. Going on a hot date?" Olivia asked teasingly.

"I'll let you know how hot the date is once it's over," Lincoln bobbed his eyebrows.

"You're pretty confident it'll go any further than food," Olivia smirked. She was so grateful of her mother agreeing to watch Henry tonight. She hated leaving Henry, especially after everything that happened, but her mother wouldn't let her change her mind about this, insisting she have a night out with her boyfriend, no matter how late that "night out" ended... or early. Olivia had blushed at the implication a little but thanked her mother anyway.

"Oh I'm very confident there will at least be kissing," he smiled that damn charming smile again.

"Is that so? So who is this lucky woman you're taking out?" She asked as she moved closer to him, breathing in his aftershave and shivering pleasantly.

"Someone beautiful, hilarious, and perfect..." Lincoln said, his lips stretching attractively with his wide grin.

"Look at you, Mr. Suave..." Olivia teased, leaning in to kiss him. Lincoln smiled into the kiss, moving his hand down her back, along her black dress. "Careful, leave some of that for later," Olivia winked, catching his hand from wandering further down. Oh he just hoped she wasn't joking about that! The two made their way out and as they walked, Olivia stole secretive, appreciative glances at Lincoln, who chose to wear a dark blue button-up shirt – with the first two buttons left unbuttoned, revealing a little chest-hair that peeked through - black slacks, and his only black dress shoes. If she had known he could look this alluring, she would have gone on a date with him long ago.

The drive to the restaurant was in comfortable silence. Before they knew it, they had arrived and stepped out of the car. Lincoln went over and offered his arm, trying to be the "Mr. Suave", like Olivia had put it. Olivia just grinned at his cheesiness, though she did find it charming, and accepted his arm. They went in and Lincoln told the hostess what name they were under. They sat at their table and Olivia agreed to some wine. While she normally didn't like alcohol, this blend of red wine they had was had just the right amount of alcohol flavor and fruity without it being like juice.

Through dinner they talked, teased each other and joked around until they were red in the face. Most of the jokes surrounded poor Charlie though, even if they only meant it fondly. When a song Olivia recognized started playing, she grinned and stood up. They had already eaten so they didn't have a waiter to wait on them, though they hadn't yet paid the bill. "Come on, dance with me!" Olivia said, tugging at Lincoln's hand. It kind of reminded her of her time with Peter... but then, Peter had been reluctant, Lincoln on the other hand hopped out of his seat and spun her around before pulling her into his arms.

Lincoln had this way about him that made Olivia's mind focus solely on him. Then again, that wasn't very difficult. While she no longer pined for Peter, as little as that was anyway, she knew she had to eventually and somehow let him know about his son, but her heart, it belonged to Lincoln Lee. The fast-pace of the music was different than the type of music you'd normally hear in a fancy restaurant, then again, this was one of those modern, youth-inspired places. It had a dance floor and everything.

While they danced the room felt like it started to heat up a little, or maybe it was the fact that they were so close to each other that they could feel the elevated heat coming off each other in waves. They danced and laughed, moving with the beat and focusing on each other. The other people around them was nothing but a blur, the music more like background sound than anything else. They eyes locked on each other and their lips met, as if attracted to each other like magnets.

Hands on their bodies, hips swaying, rubbing, breathing heavy... they needed to pay that tab and get out of there quickly. Panting slightly, Lincoln paid for the meal, brushing off Olivia's protests where she had tried to pay for half. The drive back to the apartment was silent again, although this time there was an electrical charge in the air.

As they walked to Olivia's apartment, they could both feel a change in the air. One look at him and Olivia knew what it was he wanted, he'd never do anything without her permission, but she knew the desire was very strong and very there. And so was her's. So, she decided to convince him she was all up for it too, after all, she had told him if he played his cards right she'd invite him to spend the night, hadn't she? And he certainly did tonight. After making sure no one was in the hall, Olivia all but threw Lincoln against a wall and devoured his lips. Lincoln was a little surprised for a moment... but only for a moment.

Lincoln responded eagerly, drawing her closer, pushing his fingers through her hair, battling her tongue with his. The couple stumbled down the hall, making desperate attempts to open Olivia's apartment door. When it was finally open, they fumbled inside, their hands still on each other. "I still need to pay you back for embarrassing me," Lincoln reminded her suggestively, his hands hot on her hips, where he held her as she backed them up. He kicked the door shut and watched her pull her jacket off and kick off her shoes.

"Oh?" she asked, playing like she didn't know what he was talking about. She held still as he wrapped his arms around her, taking his time to unzip her dress while slowly moving his fingers along her exposed skin as he did so.

"Mm-hm, you're in for it now..." he grinned, his voice low. This time, Olivia allowed herself to be affected by his sensual smile. Was it even legal to look that attractive? God, had she been blind all this time?

"What ever will I do?" She said with a smile of her own, stepping out of her dress as it pooled at her feet and drew her arms around his neck, pushing her own body against his. "I guess I have no choice," she shrugged, grinning.

"That's right," Lincoln agreed. "As your commanding officer it's my duty to discipline you for insubordination," he teased, leading Olivia into her room after Olivia locked the door and reset the alarm. While Olivia was certainly not the type to be into S&M, the way Lincoln mixed business and pleasure like that made her positively quiver with anticipation.

"Gee, I hope you'll go easy on me, sir..." Olivia grinned. Lincoln merely smirked and pulled her into another deep kiss. Their mouths worked almost as quickly as Olivia's fingers did with Lincoln's shirt. Soon, that was off and they had reached Olivia's room. Lincoln kicked off his own shoes while Olivia ran her fingers over his broad physique. For a moment, she had to wonder if this really was a good idea. "Linc, what if I become..." but Olivia trailed off when Lincoln produced a familiar looking packet. "So, you've been waiting for this, have you?" she grinned, relieved.

"Actually, I honestly have no idea where I got it... no, I'm serious!" He laughed at her tolerant look. "I found it in my laptop case this morning, Charlie must have slipped it in when I wasn't looking or something... you know, he's been trying to get me to ask you out for a long time," he commented.

"Has he?" Olivia questioned distractedly, allowing Lincoln to guide her against the bed, crawling backward as he all but straddled her.

"Oh you wouldn't believe how much of a pest he's been..." Lincoln said offhandedly as he crawled over her, holding himself up on his palms though his lower-half was pressed suggestively against her. Olivia's next response was a low groan as Lincoln found the soft spot on Olivia's neck, kissing and sucking on it enthusiastically. The roughness of his beard combined with the seduction of his tongue and lips on her heated skin was starting to drive her crazy... and she wanted more.

"Lincoln..." she sighed, reaching over to unbuckle his pants as he trailed hot, wet kisses down her neck and collar bone. They slipped out of their remaining clothes, exploring each other a little before urgency took control of them.

Breaths mingled and their limbs tangled. Urgency and desire reigned supreme as they lost themselves within each other. Olivia let out a breath, gasping softly as she ran her hand through his hair frantically, pulling him closer while the other hand squeezed his shoulder. She honestly didn't know how long she would be able to last. The things Lincoln could do to her... it was truly unbelievable.

Olivia was again eternally grateful to her mother; if Henry had been there he would have surely been woken up by their cries of pleasure. Who knew this kind of thing, at least with the right partner, could make Olivia Dunham so vocal? Then again, Lincoln wasn't that much quieter. When the lovers fell upon the bed, spent and utterly satisfied, they took their time to kiss and caress each other until they fell asleep from sheer exhaustion in each others' arms.

TBC...

End A/N: It's about damn time! If enough people ask, I might write an M rated one-shot version.
