AN:So firstly, thank you to everyone who review the story. Your kind words and appreciation for my writing lifted my spirits and inspired me to continue this story instead of working on the some of the requests that I've been putting off. I had always intended on writing more for this story, I just wasn't going to do it immediately. But like a teenager having his first cigarette, I gave in to peer pressure. And also thanks to those people who PM'd me with their requests and ideas. I've got some great planned stories now, my list of ideas and requests growing larger and never shorter.

So without out of the way, I hope you all enjoy this new chapter. As a point of reference, this story takes after Chuck vs the DeLorean, so Chuck has met Jack Burton and has some idea of Sarah's childhood. Also fair warning though, it does get a little bit depressing at the end, but its setting the scene for the next chapter, will be pretty much all happy happy. Hopefully, that one will be out by next weekend, but I make no promises.

And don't forget to review.

Disclaimer: I don't own Chuck

Two hours after Team Bartowski, and Bryce, left the mansion where Chuck and Sarah had furthered their working relationship, they were back at Castle delivery their report to General Diane Beckman, who Sarah was sure could notice the oddity of the operatives before her, even on the other side of a video screen. Whether it was from Bryce's scowl, Casey's smug smirk, Chuck's uncomfortable yet strangely happy expression on his face, or the fact that she hadn't stopped smiling since they left that now famous room in the mansion, Sarah was sure Beckman realised that something was going on. However, as the mission was successful, she didn't seem to care all that much.

"Excellent work team," the tiny general said, ignoring the strange combination of facial expressions on the people gathered at Castle. "A courier will drop by Castle tomorrow morning to pick up the data. Now if there's nothing else…"

"Actually General, there is something else," Bryce interrupted before Beckman could sign off, drawing an annoyed look from the diminutive woman. "During the mission, when they were searching the first room and spotted the camera, Chuck took advantage of the situation and had sex with Agent Walker."

Sarah fought the urge to roll her eyes at her former partner. She saw this coming a mile away, but did he have to sound like a spoilt nine year old? However, before she could say anything in defence of Chuck, a derisive snort coming from the General caught her and everyone else in the room, by surprise. "And would that make you the pot, Agent Larkin," she questioned mockingly. "Or the kettle?"

Chuck managed to hide his snicker by coughing, while Sarah brought her hand to her face to hide her smile. Casey on the other hand made no effort what so ever to hide his own amusement at Bryce's sour expression. Beckman noticed their merriment, and while she was always happy to cut down those smug CIA assholes, the issue still needed to be address. "Regardless how much a hypocrite Larkin is, this is something that cannot be condoned. Major Casey" she said, directing her attention to her trusted subordinate "Give me your assessment of what happened."

"Yes Ma'am," said the NSA agent. "As the lovebirds here were searching the first room, Bartowski noticed a security camera in the room, and correctly asserted that they would draw unwanted attention and possibly blow their covers if they just ran out of the room. He quickly came up with the plan for me to search the other room while Walker and Bartowski 'distracted' the guards watching on the camera."

Beckman's brow furrowed. "I don't understand why they didn't just talked or something like that," she said frowning. "Married couples do that all the time at those kinds of parties."

Casey got this gleam in his eye as he smirked at Bryce, who quickly realised this wasn't going to go his way. "That's what Bartowski said," he said, nodding to the human Intersect, who was grateful for the support. "Super-Agent Larkin here felt, in his infinite wisdom, that Bartowski and Walker would have a better cover if they went as Charles Carmichael, software tycoon and Eva Anderson, his married assistant," he concluded as he enjoyed watching Bryce squirm under the General's glare as she realised the significance of Sarah's cover.

"Agent Larkin," Beckman hissed from her office. "You have been a CIA agent for almost seven years correct?"

"Yes ma'am," he replied, unsure where this was going.

"And during that you've been to numerous parties like this, correct?"

"Yes ma'am."

"And you're usually partnered with a female agent as these events, yes?"

"Yes ma'am, usually with Agent Walker."

"And how many times was your cover anything other than a married couple?"

"Er… well," Bryce stammered, realising what the General was getting at.

"How many Larkin," she barked, causing all of Castle's occupants to jump.

"None ma'am," he said with resignation.

"Exactly," she hissed, glaring at Bryce. "Bartowski hasn't had any kind of espionage training apart from watching Bond films and yet he's able to grasp why we use married couples as a cover, whereas you, an agent for almost a decade is too busy acting like a jealous boyfriend. This was a simple mission Larkin, an incredibly simple mission that would help in our war against Fulcrum, yet because of you, this could have ended with one of our best agents and the most important intelligence asset in the world being compromised. Isn't it lucky for us that Mister Bartowski isn't as hopeless as some other operatives I could mention?"

Beckman continued to glare at Bryce, who had the good sense to keep quiet. For Casey it was like Christmas had come early, seeing that arrogant punk being knocked down a few notches after being an asshole to Chuck for the better part of the week. It was almost good as shooting him. And hopefully with this new development in Bartowski's and Walker's relationship, it'd mean less lady feelings for him to deal with. Sending one last glare towards Bryce, the General wordlessly signed off, allowing him to breathe easier.

"Well," started Casey. "I guess we're done here. You guys can leave; I'll finish up the report."

Bryce nodded and then turned to Sarah, his arrogance returning as if he hadn't just been scolded by a tiny brigadier general. "Well then, Sarah," he said smoothly, smirking at her. "Let's go back to your hotel."

Although Chuck's face fell at Bryce's words, Sarah simply rolled her eyes at her former partner. For a spy who was famed for being unpredictable, he was awfully easy to predict. She knew that after that show with Chuck, he was going to want to 're-establish' himself as the alpha male. And he would definitely make her submit like she had with Chuck, and probably try to fuck her ass. 'Well too bad for him,' she thought, 'because once you go Chuck, you never go back'. The only thing she had lied about during her session with her sweet nerd was their names. Everything else, about Chuck being better than Bryce, about her ass being just his, about her belonging to him, she had meant it all, from the bottom of her heart. Given how things usually were with their relationship, she wasn't sure if he picked up on her honesty, which given his current downtrodden expression seemed unlikely. 'Oh well,' she thought, smiling inwardly, 'looks like I'll have to spend the rest of the night making him see that I meant everything'.

"Sorry Bryce," she said, not looking apologetic at all. "Chuck and I have to do cover maintenance tonight."

Sarah smiled as Chuck perked up, no longer looking like someone had kicked his puppy. Bryce, on the other hand, dropped his smirk and adopted a rather sour expression. "Tonight?" he questioned, scowling. "But I thought we could…"

"Of course tonight Bryce," she said rolling her eyes again, knowing exactly what he thought they could do. "Chuck, what did you tell Ellie about where you were going tonight?"

"That you and I were going on a date," came his response.

"Did she see you in the tux?"

At the human Intersect's nod, she addressed Bryce again. "If Ellie saw Chuck in a tux, then she's probably thinking we went somewhere fancy." Again Chuck nodded to confirm her assumption, to which she continued speaking. "And it'd be unusual for a couple who has been dating as long as we have to have dinner at a fancy restaurant and not spend the night together. And because you're too cheap to get your own room, Chuck and I will have to go back to his place."

"Can't you just tell her you've been fighting then," complained Bryce.

Sarah gave an uncommitted shrug. "I could I suppose," she said, but continued before Bryce could say anything else. "But Ellie wants Chuck to be happy, and she likes us together. If she hears we've been fighting, she's going to try and fix it, which will mean to start digging into our relationship."

"And who knows what secrets Ellie Bartowski will find," Casey interjected snidely from where he was writing the report. "Especially of the top secret variety. Woman's like a bloodhound when it comes to secrets."

"So send him home with Casey instead," said Bryce, glaring at the larger man.

The NSA agent simply snorted. "That's worse than the fight idea," he said as he too rolled his eyes at one of his favourite live target. "Did you forget moron that I live right next door to Casa Bartowski? If Ellie saw the nerd here staying the night with me instead of Walker, then I'm on the next flight to Afghanistan because there's no way I'm sticking around to deal with that woman shaped hurricane."

Seeing Bryce about to say something, Casey kept talking, cutting him off. "Besides, this is my night off from geek watch duty. I'm not giving it up just so you can flounder on top of Walker like a virgin on prom night while she looks bored and wonders how much longer she has to deal you before she can go back to some Bartowski lovin'."

Casey took great delight in the way turned red, whether from anger or embarrassment, it didn't matter. "Fine then," Bryce snarled at the man who had a tendency to shoot him. "I'll pay for Chuck to stay in a hotel somewhere."

"Woah hang on a sec," spoke Chuck before anyone else could. "As much as I'd like to spend at least one night free from the total government invasion on my life, aren't I supposed to be under constant surveillance? I'm not sure the general is going to go for that, especially when Sarah is still on duty. And anyway, shouldn't you get a full nights rest before you go back into deep cover?"

"Chuck's right," Sarah agreed, cutting off Bryce. "You know just as well as I do, that deep cover mission can take it out on you. You should use tonight to get a good night's sleep."

It seemed that Bryce had run out of arguments and realising that he wouldn't be sleeping with Sarah tonight, he gave off an angry growl before he stormed away, the sound of Castle's automated doors confirming his departure. Again, Sarah rolled her eyes at his behaviour, before turning a smile towards Chuck. "Just wait here Chuck, I need to go change," she said, enjoying the smile he gave in return.

The ride from Castle to Chuck's apartment was quiet, but not uncomfortably so. It mostly consisted of Sarah sending him sly smiles while driving. For Chuck's part, he seemed to be more confused than anything else, wondering on whether he should apologise for his actions, or thank every deity that has ever existed because he had sex with Sarah freaking Walker. She could see the gears moving in his head, worried about where they stood in their relationship. She couldn't help but feel guilty for that, after all, Chuck wasn't exactly that confident to being with and the emotional turmoil she put him through over the course of their relationship probably made him even less certain about where he stood with her.

Something else she felt slightly guilty about was how she was actually happy at Chuck's confusion and worry. Had it been any other guy she had said those things to, they would have been strutting around like she was nothing but property to be owned. Hell, Bryce had been strutting like that, and she had spent half the session talking about how bad in bed he was. Fortunately for her, Chuck was not like other guys. She had told him that she wanted to be owned by him, and rather than treating her like property, he still saw her as a person, as someone he loved and cherished.

It was just before midnight when Sarah's Porsche pulled up in the front street of the Echo Park apartment complex. Wordlessly, they both exited the car and walked over the street and into the courtyard. Chuck couldn't help but stare at Sarah's form as it filled out the dress that she had changed into. It was a dark blue colour, one of his favourite colours to see her wearing actually, that fitted her like a very tight glove. It flared out at the hem which finished around her mid-thigh, showing off her gorgeous long legs while the thin spaghetti straps were barely noticeable when his eyes were instantly drawn to the ample amount of cleavage displayed.

Every time he looked at her, his mind was instantly reminder of just several hours ago, when those wonderful legs were wrapped tightly around his head, or how those bountiful breasts bounced in rhythm to his thrusts, or how those delicious moans were consistently escape through those incredible lips.

Chuck shook his head in an effort to refocus himself. If he kept staring at Sarah like that, then he'd never get through the door. And then he'd never get round to asking all the questions swimming around in his head, the most important being 'What happens now'. While he was absolutely positive that Sarah had enjoyed their coupling, he was confused as to what it meant for them. Were they in a real relationship now or would things just go back to the way they were, with the incredible memory of having sex with Sarah Walker forever etched into his mind? He didn't know and though Sarah's smile hadn't left her face, he still couldn't get a read on where her mind was at.

Not wanting to wake Ellie or Devon by going through the front door, the pair quietly snuck through the Morgan door and straight into Chuck's room without bothering to turn the light on, where they sat down side by side on his bed, their comfortable silence from the car becoming more awkward. "So… what now," Chuck asked after a few moments of quiet.

"I suppose you want to talk don't you," she replied, teasingly.

"Well yeah, I'm a little confused on where we stand," he answered her. "And besides, what else would we be doing?"

"Well personally, I'd like to be having more sex," she purred, enjoying his jaw dropping. "But I suppose we can talk for a bit first."

"Er wha… what?" Chuck finally managed to choke out after spluttering for a good minute.

Sarah couldn't help but giggle at his reaction. "I thought we established back at the mansion at I was your slut?" she said with a look of mock innocence. "And don't sluts have sex with their master?"

"Well, yeah," he said, still unable to wrap his head around what was happening. "But I… I thought that was just an act?"

"The only thing that was an act about tonight was our names," she said, as she moved from his side and onto his lap, causing her to smile as Chuck visibly gulped. "Everything else, about me being your little anal whore and all that, that was real Chuck. I meant that."

With that she placed her hands on the side of his head and pulled him into a gentle and loving kiss. Chuck took all of five seconds to snap out of his shock and enthusiastically returned the kiss, his tongue meeting her to continue the dance they started in the mansion. He placed his hands on her smooth silky thighs and gently rubbed up and down her legs, gradually making their way up underneath the skirt of her dress. Sarah moaned into their kiss as Chuck's strong hands cupped her rear as his eyes shot open when he realised that she still wasn't wearing panties. Gently pulling away from her, the brown haired man shot her a questioning look.

"What," she said with an innocent look on her face that didn't meet the devious glint in her eye. "I thought we agreed; no more panties."

Chuck couldn't help but stutter incoherently, causing Sarah to giggle. She really did love his innocence, even with the woman, who less than three hours ago he had ass fucked to a screaming orgasm, sitting on his lap without any panties on. Before she could re-initiate their kiss, Chuck found his voice. "What about the bugs," he questioned, worried about other less fun repercussions. "Aren't they still active?"

"They are," Sarah confirmed. "Casey will be out for the rest of the night, and will be waiting at Castle for the NSA courier before he has an afternoon shift at the Buymore. He told me to make sure I take the footage with me before I leave tomorrow, because he said and I quote 'If I have to listen to you two playing hide the Intersect again, I'm going to shoot myself then the both of you morons'. Didn't really ask how he planned on doing that though."

"But won't you be reassigned if we keep having sex," he asked, worried about that particular consequence.

The blonde goddess just shook her head. "A handler's job is to control an asset and get the most out of them," she said, choosing her words carefully. "Sex can be a way to accomplish that. Its strong emotional feelings that get a handler reassigned."

Worry flickered across Chuck's face. "Is-is that happening here," he stammered, unsure if he wanted to know the answer. "Is this just away to control the Intersect?"

Again, Sarah shook her head. "No Chuck it isn't," she replied, her face alight with honesty. "If I were controlling you with sex, then I would have been having sex with you from the beginning, and if you did something stupid, like for instance getting out of the car when we told you not to, then I would cut you off. But I'm pretty sure I don't have the strength to make that promise, not after the mansion. One look from those puppy dog eyes and I'd be bent over the nearest desk begging you fuck me."

Chuck seemed to get a faraway look on his face at the thought of her bent over, which caused Sarah to let out a small giggle. She gently patted his cheek to snap him out of his daydream. "Come on, Chuck," she said to him playfully. "You never have to day dream about having sex with me again. I'm yours remember? Your slut to fuck whenever you want."

She gave his lips a slight peck before she slid off his lap and onto the floor in front of him, resting on her knees. While locking her blue eyes with his brown ones, her hands quickly undid his belt and zipper, and pulled out his half hard member. Grabbing it at the base, she brought her mouth down onto the tip, kissing it lovingly, before bringing the whole cock head into her mouth and sucking on it like a giant lollipop.

Chuck could hardly believe it. For the second time that night he had his dick in Sarah Walker's mouth and once again she was basically devouring him like her favourite snack. He couldn't help but let out a loud moan as she took more of him into her mouth, her tongue sliding around the flesh into her mouth while her hand stroked what she couldn't get in. He brought his hand to her head and gently tangled it in her hair, his hand moving along with her own movements as her head bobbed on his prick. "Fuck Sarah," he moaned. "Your mouth feels so good."

Her response was to look up at him, and as once again blue met brown, Chuck could barely contain himself. The woman he loved was staring up at him, his cock almost entirely in the mouth, more than any other woman had managed to fit it. The sight of this blonde goddess on her knees staring up at him longingly compounded with the sensation of her sucking his flesh rod like rock candy sent him over the edge. Groaning loudly as he came, he couldn't help but force more of this prick into Sarah's mouth, causing her to gag slightly, but still she managed to keep her orifice firmly in place and making sure he spent his load inside of her gullet. As he released several more spurts down her throat, she continued to stroke him with her mouth, coaxing as much of his cum as she could. Even once it become apparent that she wasn't going to get any more out, she kept on blowing him, preventing his member from softening.

Finally after several minutes, Sarah pulled her head off from Chuck's phallus, sucking extra hard on the tip before letting it go with an audible pop, a string of saliva trailing from her lips to her new favourite. "Mmm," she groaned erotically. "God Chuck you taste so good. Maybe I should thank Ellie for your good eating habits, hmm?"

Without another word, Sarah stood up and kicked off her heels, and motioned Chuck to do the same with his shoes, before she quickly slipped the straps of her dress off her shoulders, allowing it to fall off her magnificent body and pool at her feet. Placing her hands on her hips, Sarah looked at Chuck expectantly. "Well," she questioned, raising an eyebrow. "Does my master approve of his slut's body?"

She giggled when he mindlessly said "Fuck yeah."

"Well then Master," she purred. "How about you get out of that silly suit, lay down on the bed and let your slut take care of you"

Sarah was positive she had never seen anyone undress that quickly before. Chuck's clothes practically flew off his body as he almost tore them to shreds trying to get as naked as humanly possible. Once his clothes were off his body and at various places in his room, he followed Sarah's instruction and lay on his back on his bed. "Come on Sarah," he said, stroking his member as she prowled towards to himself like a lioness. "I want to fuck you again."

She giggled at his impatience. "Of course Mr Bartowski," she said huskily as she crawled over him to position her pussy above his throbbing arousal. "Whatever my master wants."

Without hesitation she plunged down on his rod, eliciting loud exclamations of pleasure from both of them. "God Chuck," Sarah cried, moving down as far as she would go. "You feel so good inside me."

"Fuck, your cunt feels so tight around my cock," he replied as he placed his hands on her hips. "Why don't you show me how good of a slut you are and ride my dick?"

Once again Chuck's demeaning words simply turned her on more. Normally, Sarah would have been surprised at her sweet nerd talking to her like that but considering how all she could focus on was the glorious piece of man flesh impaling her soaked womanhood, his words weren't really that far from the truth. She lifted herself up slightly, making sure that Chuck's member wasn't going to fall out, before gently dropping herself down, with her lover's hips thrusting upwards on her downward descent, causing her to moan at their point of collision. Soon their movements began quickening in pace, Sarah's juices making it easy for her to slide along Chuck's pole. "Oh Chuck," she cried as he began toying with her clit. "You fuck… your slut so… good."

"God you're so tight," he groaned.

"It's oh… it's because your so… big," Sarah panted as his manhood touched her cervix. "Yours is the… biggest… hardest… cock I've ever had… in my tight… little pussy."

The human Intersect's response to that was to grunt loudly as his hands reached up and placed themselves on Sarah's perfect breasts, to which he began roughly caressing the soft orbs of flesh. The blonde goddess on top of him mewed at the sensations, and placed her hands on top of his to which they joined in the manhandling of her tits.

"Mmm… oh god Chuck," she moaned, the stimulations quickly bringing her to the edge. "I… I'm so close."

"Urm… M-me too," Chuck stammered, relishing the feeling of the blonde's pussy squeezing him. "W-Where…?"

"In me," she pleaded, desperate for his seed. "I… I need you… inside me…"

"But wha… what about…" he struggled to say, rationale thought being overwhelmed by his lust.

"It's fine Chuck," Sarah practically screamed. "I'm protected… just shut up… and fuck meeEEEEEEE."

The CIA agent's sentence trailed off as she was overcome by an intense feeling a pleasure, rivalling that of what she felt in the mansion. Her juices washed over her lover's prick, covering him in her fine nectar and making it easier for him to continue sliding into her pulsating vagina. The way her muscles massaged his now slippery hard on simply felt too good to Chuck, and grabbing her by the hips, he gave a final thrust, exploding inside her and painting her insides white. "I love you, Sarah," he cried as his emptied himself inside of her.

Sarah wasn't sure if it was the feeling of his releasing inside of her, or his heartfelt words, but regardless of what pulled the trigger, she came again, just as powerful as the last one, causing her vision to blur and to fall forwards onto Chuck's chest. However, it wasn't until he was wrapping his arms around her did the full weight of his words fall upon her. In hindsight, she should have seen this coming, but had been so caught up in the physical pleasure that she didn't even think about the emotional complications. "I'm sorry," she said, her previous elation fading under the weight of a heavier situation.

For a moment, Chuck remained silent, replaying the last several minutes in his head. When he finally realised what she was apologising for, he spoke softly into her ear his reassurances. "It's ok," he whispered gently, as he slipped out from her. "You'll tell me when you're ready."

He felt her shake her head on his chest. "No Chuck, that's not it," she said ruefully. "I care about you, Chuck, please believe that. And if my bosses knew how much, I'd be reassigned within the hour, but at the end of the day, I'm a spy, and that's all I know how to be. Someday you're going to get that thing out of your head and you'll go back to your normal life and that's something that I can't give you."

"So what does that mean for… us," he queried, his good mood disappearing as realisation hit him about the complication situation they found themselves in.

"I guess," Sarah sighed, searching for the right words. "I guess we just make the most of it. Enjoy each moment together as if it's our last."

Chuck actually smiled at her, although it didn't quite reach his eyes. "Carpe diem, eh," he said, gently stroking her back. "That's pretty deep."

Her shoulders gave a slight shrug. "Someday you'll be free of the Intersect and the spy life and I'll be going back to knife fights in Jakarta. When that day comes, I want as many happy memories of our time together as possible."

Chuck nodded solemnly. "Well I guess this is enough then."

Again the spy shook her head. "For any other man, this would be enough," she said, lifting her head to look directly at him, resting her chin on his chest. "But you Chuck, you're so much better than other men. You want and deserve so much more than I can give you."

He wanted to argue with her, that this was enough, but he knew he'd be lying and she would spot it instantly. Truly he did want more. He wanted to get married surrounded by family and friends, have a few couple of children who he could teach to be superheroes and to grow old with the love of his life, tell her he loved her every single day. The problem was, was that the more time in spent with Sarah, the less he was sure that he wanted any of that without her.

"I'm sorry," he sighed. "Guess I kinda ruined the mood huh?"

"It would have come up sooner or later anyway," she said, and when she continued, Chuck could almost hear an edge of desperation in her voice. "And please, Chuck, don't ever be sorry for loving me. It's probably selfish of me but it's nice to know that there's someone real in the world that feels that way about me."

"I don't think I could ever be sorry for loving someone like you Sarah," he whispered gently to her, pausing for a moment before adopting a playful grin. "This still means you're my slut though right?"

His tone was mischievous and light hearted and it worked to lighten the moment. "Of course Chuck," she giggled. "Any time you want me, I'm yours to do whatever you want with. I'd appreciate if you gave me the same consideration though."

"Geez I dunno," he said, throwing her his Carmichael smirk. "Giving my slut sex whenever she wants? She might get a high opinion of herself."

Sarah giggled again as she readjusted herself so that her naked body was pressed against Chuck's while her head remained on his chest, both of them closing their eyes. As she allowed the sound of his heart, the heart he had so easily given to her, to lull her into sleep, she thought about what she would do in the morning after she left Chuck's apartment. She would go into Casey's apartment and copy the surveillance footage before erasing it from the drives. She would make an edited version to torture Bryce if he came back but she would also keep an unedited version for herself, so even in her loneliest days as a spy, she would have some reminder that she was loved by the best man she ever met.

Thanks for reading, hope you enjoyed it and remember to review.
