A/N: I can't really give a proper explanation for why I wrote this without getting really uncomfortable, so I'll just go with the fact that there's hardly ANY Chuck/Sarah smut and I feel like that it's a travesty. This takes place sometime in early Season 5 (or my fictional s5), so yeah, spoilers for the Season 4 finale?

Disclaimer: I don't own Chuck or the song "Around my Head," by Cage the Elephant, OR the song "Tighten Up," by the Black Keys. If I was, well, I wouldn't be writing smut fanfiction, would I?

Enjoy, don't forget to R&R!

A Million Years

Chapter 1: Home, Sweet Home

Sarah Bartowski had greatly underestimated the difficulty in managing a successful business. Or rather, co-managing since only half the responsibilities pertained exclusively to her. It had been just another grueling day that involved literally no espionage whatsoever, but massive paperwork and important phone calls instead. Castle was still in the process of being revamped to meet the fledging spy firm's criteria as a suitable base of operations. They'd taken every precaution imaginable to ensure that it would be safe for all of its occupants as well as the many secrets that were encrypted inside databases as well as in a certain bearded spy's brain. The remaining components of the security system was being installed and due for completion sometime that weekend. Sarah had to admit she'd never seen anything quite like it before. The CIA may have had the latest technology in their possession but none of it could compare to what Chuck had devised for Carmichael Industries.

It was on that Friday afternoon when Sarah was finally allowed to clock-out and leave. She met her weekly quota of accepting or rejecting future clients' job offers, and finalizing agreements with various defense contractors for the use of their weapons, contacts and gadgets. It was a done deal and her conscience was free for the subsequent days she had off. Meanwhile Chuck remained at the Buy More with Morgan and Casey. He had to not only keep his cover intact, but he was determined to work all the kinks of Castle's security protocols before he retired for the night. Sarah was proud of her husband's dedication. Though it still irked her that he wouldn't return home till later that evening when the electronic store closed shop.

Normally Sarah would be overjoyed to unwind at their apartment, now refurbished thanks to a very generous wedding gift from Hartley Winterbottom. But once noticing how strangely vacant the place was without Chuck, the whole concept of leaving early felt bittersweet. It had only been a measly hour since they parted ways and yet she craved desperately for his company.

Nowhere was truly home without Chuck.

Look what marriage has done to me, she thought in amazement. I'm starting to sound exactly like Chuck. This didn't strike her as an earth-shattering revelation. Sarah was a different person (a better person) than she had been over four years ago. She'd much rather prefer being hopelessly in love with the most charming man in existence than to revert to her old ways as a cold, heartless spy.

That window of opportunity had long passed and Sarah couldn't be happier. She sat curled upon the sofa with a mug of freshly brewed coffee held within her grasp. The television was on and flickered with random images. There wasn't anything remotely interesting on at this hour so after indulging in one last sip, Sarah stood up and turned the expensive plasma screen off with the flick of the remote.

After rinsing the empty mug in the kitchen sink, Sarah decided to retreat for the bedroom. When she walked inside, her sights fell onto the comfy queen-sized bed. It was amazing that even after acquiring what Chuck dubbed, "a cool billion dollars," they had spent the funds wisely and left their bedroom (which held so many memories anyways) more or less unchanged. The size remained as it was; the walls still adorned with movie posters and Comic Con stickers. The only addition was the clap light which apparently was a childhood dream for Chuck. But other than that, there weren't any huge cosmetic alterations.

Sarah was wary of change in any capacity. So with her life almost entirely overwhelmed by it, she was relieved that at least one place survived the transition. Now half of her desired nothing more than to just crawl underneath the covers and sleep. But then she remembered that Chuck would be home eventually, probably to discuss the growth of Carmichael Industries and so she resisted the temptation. It'd be selfish to disengage from co-founder duties just because it inconvenienced her. Plus, she really wanted to be awake to see Chuck. There was no doubt that he was going to be exhausted. To build a business from the ground up while training Morgan to master the Intersect was an arduous task. Chuck needed to be rewarded for his efforts. Luckily for him, Sarah knew exactly how to go about doing that.

The first step was to freshen up. Sarah stripped off the sleek black outfit she'd been wearing for appearance's sake. Now she was left bare with the exception of her matching bra and panties. Once crossing the threshold that led directly into the bathroom, she turned on the showerhead before shedding the remaining articles of clothing and jumping inside. The hot water cascaded over her naked figure and boxed the stall with an overwhelming amount of steam. Sarah relished in the heat; allowing the moister to seep into her aching muscles, relieving them of almost all their tension.

Sarah took her time getting clean. There was nowhere she had to be and everything of importance had already been taken care of. For once in her life, things weren't too hectic. It had been nearly two months since she and Chuck tied the knot and since then, their passion had ignited to a whole new level of love and satisfaction. Even if work had them too busy for more intimate sessions, they'd sacrifice until the time was made. It seemed like the metaphorical flame couldn't be extinguished despite what other couples had forewarned them in the past. On top of that, Chuck had managed to accept that the Intersect was gone forever and moved forward with his life. He had taken it in stride, finding his place in the spy world without having to use the supercomputer as a crutch. His newfound confidence absolutely thrilled Sarah. There was no trace of the self-deprecating, underachieving nerd she pitied so long ago. However she was certain Chuck would never outgrow his nerdiness and was perfectly content with that.

Her lips curved upward into a crooked smile while she daydreamed about her husband.

It was impossible to contain her excitement for his inevitable return to La Casa de Bartowski.

The next half hour passed by uneventfully. Sarah finished her shower and now felt cleansed and rejuvenated. She was dressed in Chuck's favorite purple lingerie, currently perched at the edge of the bed as she painted her toes. The nail polish she chose was pale blue, another one of her husband's preferences. He often made the remark how it complimented her eyes of the same shade. Not many men noticed subtle details like that. But then again, most men weren't her Chuck.

Sarah began humming as she put the finishing touches to each toenail. The tune was catchy and she remembered hearing it that morning. Chuck had been fiddling with the satellite radio on the drive over to the Buy More when the song came blaring out of the speakers. Sarah was unfamiliar of most bands in general while Chuck proclaimed himself a music connoisseur. So it came to no surprise that he memorized the lyrics, treating her to an especially amusing performance before they pulled into the Burbank Plaza parking complex.

"I don't think it's very nice to walk around my head all night," mumbled Sarah under her breath. "You got me tangled like a braid tied-twisted. I don't think its fair, do you-oooooooh?"

She smiled as her mind trailed off to Chuck again. Somehow everything related to him one way or another. This song was no exception and it made her miss him even more terribly. She blew the nail polish dry, pausing when hearing the jingle of keys; the front door to the apartment creaking open, then as footsteps tread lightly across the wood flooring. Sarah did not have to channel her spy instincts to know who it was. The lovely and familiar voice echoing from the living room confirmed her suspicions.

"Out here on the flip side, you know I took the long way round. Cause all I really am is a homemade elevator…"

Sarah's ears perked up. There was nothing quite like when Chuck sang. He sorely lacked the confidence to do it in public and usually kept his talent to himself. That was unless he was drunk. Sarah recalled on their last group date night where Chuck had been tricked into singing at the karaoke bar. Tricked might've been too harsh. He was convinced. And convincing Chuck to make a fool out of himself five beers in wasn't that impossible of a task in all honesty. Devon made it actually look pretty easy. But then again, he was awesome by the very definition of the word.

Little did anyone know that Chuck was in fact, a fantastic singer. He flubbed a bit on some of the lyrics, but other than that, his rendition of The Black Keys "Tighten Up," was near perfection. His voice in particular was swoon worthy. The women at the bar were clamoring for him once the song ended and Sarah had to summon all her self-control not to throttle each and every skank for flirting with her husband.

At least she had been the only one taking him home that night.

"Blinded by your sunshine, put you on a plane to old Paris, I laid my cards down on the table." Chuck continued singing and broke Sarah from her reverie. She was pleasantly surprised to find that it was the very same song she had been humming to just moments ago. His voice grew louder as he neared their bedroom. "I don't think it's very polite to walk around my head all night. You got me tangled like a braid, tied-twisted…"

When she realized that Chuck was going to burst into the room at any moment, Sarah quickly set aside the bottle of nail polish and scooted her body to the center of the bed. She scrunched up her blonde curls to give them a slightly rumpled appearance, and then adjusted the lingerie so that it'd leave nothing to the imagination. Right on time, the door was pushed ajar and Chuck poked his head inside. Seeing him caused her face to brighten considerably as she sported one of her flawless smiles.

"—I don't think its fair…" he trailed off.

"Hey, Chuck."

Chuck's eyes followed the alluring voice and then became rooted in his place by the door. He was reduced to stunned silence, his mouth slightly agape. He couldn't believe his luck; there was his wife lying sprawled on their bed wearing nothing but skimpy nightwear. She let her golden hair fly free, curling around her angelic features. Her eyes were as deep as the ocean and they matched the color of her toes which sparkled beneath the glow of the lamplight.

Didn't she tell me how tired she was before leaving Castle? Chuck wondered, clearly recalling how exhausted Sarah appeared to be the last time he saw her. But that was a few hours ago. Maybe she just had to recuperate, he rationalized. Not that he was complaining. Any red-blooded male that was confronted with a gorgeous and willing woman like Sarah would be stupid to have any complaints.

"Honey, are you in there?"

Chuck blinked. "Uh, yeah, I'm here." he replied with a shy smile. "Hi baby."

Sarah tilted her head innocently. "I could've sworn that I lost you for real this time, Mr. Bartowski. How was work?"

Chuck took a seat beside his wife on the bed. Kicking off his shoes, he said. "That depends; do you mean real work or fake work?"

"What do you think?"

He leaned forward to give her a peck on the lips. "Everything is going swimmingly, Mrs. Bartowski. The security system has been installed. All that's left to do is test its functions tomorrow and then Carmichael Industries is officially in business."

"Exciting, isn't it?" Sarah grinned. It felt like an eternity had passed since she, Chuck, Casey and Morgan first began their endeavor to get the freelance spy organization up and running. Now all their hard work was going to finally pay off.

"Very," Chuck agreed. His eyes quietly roamed her body and he added. "Though I have to say, I am quite a bit more excited about other things at the moment. What's the occasion?"

"No occasion. I just thought I'd do something nice for my husband, especially since he's been working his ass off nonstop for the past month without setting time aside for himself."

Chuck shrugged. "What can I say? I'm a Bartowski. It's in our genetic code to be hopelessly fixated."

Sarah nodded as she grabbed Chuck's tie and stroked it gently. She felt his whole body stiffen as a result. Hiding a smirk, she suggested in a low voice. "If you don't find a healthy way to release all your stress and frustrations, sooner or later you're going to explode."

"Well, I can only hope and pray that it's sometime when Morgan is around…"

She arched a brow. "How is he doing by the way? It seems like every day you keep getting more impatient with his training."

Chuck huffed in exasperation. He flopped onto the bed and stared at the ceiling fan with a grimace. "He's not taking it seriously, Sarah. I keep trying to drill it into his brain that it's not all fun and games. But Morgan doesn't seem to understand that with…"

"—that with great power comes great responsibility?" Sarah finished seemingly out of the blue.

Chuck propped himself up with his elbows, turning to face her. "How did you know that?"

She blushed and looked away. "I was cleaning the apartment last weekend when you were at the Buy More and I sort of found your hidden stash of comic books. I was bored, so I read a few issues of The Spectacular Spiderman…that's what it's called right?"

It startled Sarah when Chuck's expression went from bewilderment to total infatuation in a fraction of a second. He rolled onto his side, cupping her face with either hand before saying. "Sarah Lisa Bartowski, I have mentioned on many occasions how you have the uncanny ability to make just about anything sound sexy: terrorist groups, dinner menus, baseball statistics, movie credits…but quoting a line from a comic book was without a doubt the sexiest thing I have ever heard in my entire life."

Sarah noted the glimmer of adoration and lust that swam in his chocolate eyes. The anticipation for what would come next sent shivers of delight running through her body. She replied coyly. "You know I have other talents that involve my mouth, Chuck…"

She pressed her knee in between his legs and gently massaged his groin. Chuck swallowed hard as his hands left Sarah's face, slipping down her curvy figure to settle on her hips. He pushed her against him so he could feel her body heat and endure more friction. His eyes glazed over at the wild sensation and whispered. "I do not doubt that."

"Want me to show you then?"

Chuck stalled, conflicted. His brain instructed him to hold out for just a bit longer while his body was happy to submit to Sarah's devious ways. He continued to fight off this mutiny, struggling to answer. "As tempting as that sounds...I'm going to have to decline."

Sarah frowned. "Wait, what? Why?" Then her brows knitted together in utter mystification. "Chuck, you can't just say no and expect me be to be ok with that!"

"Look, I don't want you to be upset with me…"

She was furious. "Oh my god, Charles Irving Bartowski! Don't you dare think that I am going to listen to you ramble about work!"

"Sarah, sweetheart—"

"I just drank an entire espresso to make sure I wouldn't fall asleep!"

"That's great, now will you just please listen to me—?"

Sarah was too incensed to listen. She made a grab for his tie again, pulling on it like a petulant child. "I am practically throwing myself out at you, so you better love me!"

She's absolutely terrifying, realized Chuck as he became the victim of Sarah's grievances. This of course was usually a role frequently played by Casey in the Castle dojo. Or a punching bag. Nevertheless, this had to stop. Chuck wasn't looking forward to acquiring any more injuries outside of what sex might entail. He quickly wrapped his arms around her, knowing that she was a still a spy and could easily outmaneuver him. So he anticipated a struggle, but when his wife became restless and sleep deprived, all of her training was thrown out of the proverbial window. Finally, Sarah was secured in his embrace.

He told her softly. "Alright, Sarah you are being ridiculous."

She squirmed, lamenting. "All I wanted was for the two of us to have an intense night of seduction. There would be no talk about Carmichael Industries or the Buy More. That's all that we've been discussing for weeks!"

"I know and completely understand what you're saying," said Chuck.

Confused, Sarah went limp in his arms. "Then why did you stop me from trying to seduce you?"

Chuck answered her with a kiss on the forehead. While he held her with one arm snaked around her waist, he used his free hand to settle between her thighs. His fingers applied slight pressure, then began to rub very slowly. Sarah shut her eyes and let out a breathy gasp.

"I've been thinking about you all day, Sarah." He told her sincerely. His fingers hooked around her panties and proceeded to tug them downward. Resistance was futile as Sarah's mind went void of all conscious thought. "I know we haven't had much time alone together since our honeymoon, so I wanted to make it up to you properly." Chuck kissed her again. "This means no seductions. It's just you and me, husband and wife, having a nice romantic night alone..."

His mouth trailed from her lips and down to the underside of her jaw; sucking on a pulse point on her neck that made Sarah's toes curl. She choked out a moan when he began massaging her breasts with the hand that had been previously holding her in place. The other was still very much south. His index finger circled over her velvety folds, feeling heat radiate off her in waves. The pressure building inside Sarah was extraordinary. If he kept going like this, she'd be a goner in no time.

But once Chuck stopped, so did her world.

"Now," she listened to him say. "Before I continue can we have a truce?"

"A truce?"

Chuck absently pulled down the straps of her lacey top. "Yes, just promise me that if I release you, you won't try to maim me for upsetting you earlier. I wanted to be the one initiating tonight's activities." She sighed when her breasts popped out, nipples hard and ready like the rest of her. His fingers traced over her rosy skin then settled on her taut stomach. "So, truce?"

Sarah nodded.

Chuck beamed. "Awesome."

He dipped his head and left a path of wet kisses to valley of her breasts. Sarah felt her heart beating furiously when Chuck took a nipple into his mouth and began assaulting her with his tongue. All the while he resumed his soft languid movements with his other hand. He slipped inside her to feel a wetness coat his fingers, gently massaging her clit which caused Sarah to writhe uncontrollably.

After Chuck moved to her other breast for the same treatment, he continued his descent to her abdomen. He paused to tickle her belly button with the tip of his tongue and she burst into a giggling fit. With a satisfied smirk, he briefly removed his fingers from out of her essence and replaced them with his mouth. Sarah arched her back as she felt the pleasure intensify. Her legs fell uselessly onto either of his shoulders; heels digging into his back as he would continually bob his head up and down, tongue rolling in the depths of her arousal.

Sarah soon broke her silence with a series of moans that elevated into screams of ecstasy. Chuck teased her clit by wiggling, sucking and licking her into frenzy. When she began to unconsciously thrust into his mouth, he placed a hand at the small of her back to restrict her movement.

"God, Chuck…" she whined, "fuck!"

She screamed the instant Chuck plunged a finger deep inside her pussy, working in tandem with his tongue. Her pleasurable cries elicited something primal in Chuck, causing him to work faster and harder than before. He felt his own arousal start to hinder his performance. Groans passed his lips while he continued to devour Sarah into oblivion.

It was during these moments of extreme pleasure when Sarah had the tendency to reflect on past lovers. This didn't mean that she felt Chuck was inadequate and had to divert her attention elsewhere. It was actually the exact opposite. She enjoyed comparing and contrasting the handful of men she was forced to seduce during her stint as a spy. None of them were as selfless or familiar with the female anatomy than Chuck Bartowski. Even her former partners lacked the finesse Chuck had inherently obtained. Bryce was more focused on fulfilling his needs rather than hers. Shaw was stiff as a board...and not in the good way. Chuck proved after their first time together in Paris that nice guys who weren't born with movie star looks had to work a lot harder to earn their keep. All those years of watching porn (during what Morgan would call their awkward teenage phase) had finally paid off.

Chuck had discovered a way to perfect the art of pleasuring a woman.

"Please, baby, I'm so close…"

Chuck recognized by the high pitched tone of her voice that Sarah was fast approaching a climax. Her legs were locked around his neck and the lower half of her body thrashed for reprieve. And as much as he wanted to finish—tasting and savoring her juices, he felt the instinctual need to be inside her.

He did not hesitate to pull his mouth from her dripping essence, licking his lips as he aligned himself above Sarah. Through her sex-induced haze, she was coordinated enough to successfully undress her husband. She ripped apart his white buttoned up shirt; pulling the tie off with ease. Then she went to unbuckle Chuck's belt and remove his pants. She was impatient though, teetering on a powerful orgasm. So once his pants were gone, then the boxers came off an instant later. Her fingers grasped the base of his erection and began to pump without restraint. Chuck loomed over her, ravaging her naked body with his hands and lips; teeth grazed lightly over her collarbone and fingernails dug violently into her sides.

"Chuck," Sarah managed to choke out amongst their shared cries of pleasure. "I want you…right now."

Chuck didn't need to be told twice. He wordlessly pushed his cock inside her. At first it was slow, sliding it in and out to get used to a rhythm. Once he was buried to the hilt, Chuck increased the tempo, a snarl tearing from his throat when Sarah met him thrust for thrust. Words were meaningless at this juncture and did no justice to how they were feeling. Sarah's blue eyes were stormy and pleading. Chuck's were dark and clouded with lust. He attacked her lips with a heated kiss; tongues dancing for dominance, teeth biting into slick flesh while they continued to battle to the very end.

It was not long before Sarah finally succumbed. Her spine arched into a perfect S-curve; thighs clenching when the pressure in her navel blossomed into a powerful, all consuming release. She cried her husband's name like a reverence. Chuck wasn't too far behind either. Once her muscles contracted around his aching member so tightly, he surrendered with a euphoric groan. He collapsed on top of her, his face nestled in the crook of her neck.

Sarah breathed deeply. The musky scent of their lovemaking hung in the room. It made her feel dizzy and uncoordinated, her body reduced to jelly. A moment passed before she said lamely. "That…was…wow."

Chuck's laughter was muffled. He unceremoniously pulled out of his wife and rolled over to the empty side of the bed, sighing. "My sentiments exactly."

They both were lying on their backs, chest heaving while riding out the rest of their orgasms. Their eyes were half-lidded and unfocused. Both of their faces were scarlet; sweat soaked bodies gleamed like diamonds. They panted heavily, totally spent. But despite this, they were each sporting the Bartowski trademarked grin.

"I love you, Chuck." Sarah said a few minutes later.

Chuck snaked an arm around her waist, admiring her post-coital glow before planting a sloppy kiss against her flushed cheek. She giggled. "I love you too," he paused briefly to gather his thoughts. He cleared his throat and said in a business-like tone. "Now, I'd like to discuss a few safety procedures regarding Castle's security system…"

Before he could even finish, he was met with a playful jab to the stomach.

"Ow!"

"Not funny," Sarah tried to growl menacingly but it came off like a pout.

"You're right," Chuck conceded, rubbing his belly. "It was hilarious."

Sarah merely stared at him with an intimidating frown; this time it had the desired effect.

He winced. "Truce, Mrs. Bartowski?"

Her expression softened. "Truce, Mr. Bartowski."

They shared one final kiss and all was forgotten.

Fin!

A/N: After much deliberation, I've decided to continue this one-shot as a series detailing the adventures and misadventures of our favorite spy couple. Mostly all of them will have smut, so yeah, thought everyone should know that ;)

Here's a tease for the next update: Team Bartowski takes a trip to Syria for one of their very first jobs as the newly founded Carmichael Industries. They are tasked to locate and extract a member of the Israeli Special Forces from a terrorist compound. Along the way, Chuck and Sarah discover what a Hookah is; the kinkiness of handcuffs; and the benefits of being high, which are endless really.
