A/N: Hello all. This installment of 'One Part Me (One Part You)' includes some cute CS domesticity. I could pretend I'm not eternally bitter about my lack of this on the show so far but why bother? Instead I'm taking all that resentment and translating it into this fluffy chapter that features holiday cookies, a bit of smut, and a talk about the future and kids because why not? This story is all about instant gratification, so let's just do this. Anyway thanks for reading and I hope you enjoy!

As far as weekend plans went, there weren't very many scenarios to Emma that outweighed a good old-fashioned lazy day in. This time of year especially, with the crisp chill outside and the minimum daylight hours it felt like the perfect time to wear something cozy, commandeer a warm blanket, and just relax.

December, Emma was convinced, was created for introverts, and though she had her friends and the ability to go out and have fun with the best of them Emma also loved these quieter moments. This year, however, the best part of the quiet was that it didn't mean she was necessarily alone. She could read or vedge out in front of the TV binging holiday movies just as easily at Killian's as she could at home, and since he was adamant that he'd prefer seeing her whenever he could, she found herself doing a fair amount of that.

These visits had become so frequent, in fact, that sometimes Emma lost sight of the reality that she wasn't actually living here. This place was starting to feel like home and she was a part of making it that way. Emma had helped Killian with all of his holiday decorating (even though she didn't make a big display at her own apartment), and when she was at home she often missed the big to-do that remained here in her absence.

She also gave Killian advice when he asked for it about certain things that he was thinking of changing. Every time he then respected her opinion as if she was some sort of authority for this place instead of just the visiting girlfriend. But mostly Emma just loved the feeling that came when she was in this house with Killian. It felt natural to be here in this space with this man, to the point where at times she had to scale back from getting too comfortable.

Even that was a delicate process though because there was no one more interested in her feeling safe and welcome here than Killian. Any signs she gave of being happy he always followed as if he had a sixth sense on deciphering Emma's thoughts exactly. Half the time Emma wondered if he even wanted her to leave at all because every time she did go home he seemed to really hate it. That in turn confused Emma too because she wasn't exactly a fan of leaving. This all then begged the question of whether she should even bother going at all.

"An interesting read, love?"

Killian's question from across the kitchen pulled Emma from her personal considerations and she looked back down to her kindle. The truth was she'd barely put two sentences together since she took up this perch on a stool at the counter. She'd been too wrapped up in her own internal dialogue to really give the book much thought. Instead of getting into details on that, however, Emma made a sound of confirmation that Killian grinned at. If he saw through her fib he didn't say anything, merely turning back to the task in front of him. This gave Emma the chance to take him in again without being too obvious and she couldn't fight off the smile that came when she did.

With every passing day Emma found herself learning more and more about what made Killian the man he was. It was fascinating and endearing and at every turn she found herself pleasantly surprised in a multitude of ways. One definite fact she'd learned though was that Killian was competitive.

Emma understood that was an absolute necessity in his line of work. In order to achieve the monumental success he'd managed so far in his career, a healthy dose of competition was needed and it had certainly paid off, but sometimes this affinity for competing flowed into the rest of his life as well. That had been on display during the Thanksgiving soccer game (though in a good way that enabled the kids to get excited too) and it was apparent now in a rather different context.

"I think we've finally nailed it, love, but I'll need your feedback."

Emma hopped off of the stool and moved towards him at the comment. She was eager to find that Killian meant it this time because she'd already heard that same phrase at multiple instances over the last twenty-four hours. He'd been certain of success only for something to always change at the last possible second but it was impossible to argue with him, not when he looked like this, utterly determined and sporting a few smudges of flour on his face and arms as well as the apron she'd insisted he wear.

By 'it' Killian was referring to an ultimate, flawless, Christmas cookie recipe. Emma mentioned casually two days ago that the youth home always had an unofficial competition each year amongst the staff of who could make the best cookies. The kids voted in a blind tasting and the winner got nothing more and nothing less than bragging right for a year. That was it; there was no Michelin Star or James Beard Award up for grabs, just one year of being the reigning champ of the Little Journeyers cookie contest.

Up to this point, Emma had never won. She came close every season, but someone else always snuck just past her for the first position. It never really mattered to Emma because she and all the kids got the consolation prize of the sugar and sweetness cookies always brought, but Killian was adamant that this was her year. She would be victorious if he had anything to say about it.

Now technically, Emma had to be the one to make these cookies and she'd imparted that rule on to Killian, but her boyfriend reasoned that it was possible for him to help her finesse a recipe. As long as he took special care to catalogue precise measurements, Emma could recreate his imaginings (many of which had her flavor input as well), on her own with him merely watching and it would still be within the confines of the rules.

When Emma hesitated at that proposal, Killian continued on with more of the same logic. For one thing she'd be helping him master a segment of cooking he'd never really conquered yet, and for the other his efforts would keep Emma from getting fatigued with what he called the 'grunt work.' Emma finally agreed originally thinking that since Killian was so talented he'd stumble upon the perfect recipe early.

Boy had she been wrong on that. Not about him finding a perfect recipe because he had. Just today alone Emma tasted batch after batch of all sorts of varieties of the sinfully sweet treats that were to die for, but even her grand accolades and genuine praise wasn't enough to convince Killian. Something was missing and he wasn't going to rest easy until he figured it out.

In the meantime Emma was hardly complaining. Obviously there were far worse problems to face in this world than an abundance of cookie dough to test. She was also going to be heralded as a hero when she got rid of some of this excess by giving it to her friends and neighbors. But more than that, Emma was really and truly enjoying herself. Because even if Killian was slightly neurotic with needing to get these just right, he was completely adorable about it and enabling other holiday traditions at the same time.

Christmas music was a go and in Killian's townhouse there was a sound system that put anything Emma could ever achieve at home to shame. She also had a cup of cocoa made to perfection courtesy of Killian's secret ingredient. In theory she was reading instead of daydreaming, but either way it was the best kind of way to spend a weekend. It was domestic and completely different than anything Emma had ever known. Yet it felt like the holiday season, and Emma always struggled with finding that feeling ever since she was a kid.

Not having a family of her own meant jumping around from home to home and never really feeling like she fit in. Emma never managed to find annual traditions for any of the big holidays because she didn't have a sense of permanence. She eventually found her friends who gave her a place to belong, but even that was different because Emma knew that someday things would change.

Over the past few years Emma questioned her own ability to find love that could really fill the empty spaces in her life, but she never doubted that her friends would find such happiness. All of them trusted more easily than Emma did and it was just a matter of time before someone came and swept them off their feet. They'd get married, have their own families, and somehow Emma would be on the fringes again. At best she'd be the cool Aunt, at worst she'd be the sad spinster.

That fear that Emma sometimes fell victim to, however, had lost a lot of its impact. Since meeting Killian Emma believed there might be more of a chance than she once realized for her getting a similarly happy ending. The thought made her warm considerably and she tried to keep the line of her thoughts undetected but to no avail. Killian immediately noticed her blush and he smiled, kissing her lightly before pulling back and offering a spoon full of the dough before them.

"Now, don't go easy on me love. If there's criticism I can take it." Emma rolled her eyes even as she smiled.

"Have I criticized a single thing you've made yet?" Killian shook her head. "Right, because you've got this magical inability to mess food up. This is going to be great."

"Humor me, love."

Emma did just that and tasted the sugar cookie that Killian had put an elevated spin on. He named a range of high-end ingredients he'd added into play but Emma forget all of them in this moment. The second her tongue made contact she was hooked and she groaned aloud. Somehow he'd done it. He'd managed to blow all of the other cookies out of the water even when all of them were better than anything Emma had tasted before.

"So?"

"I don't think I can allow you to bake those…" Killian's face fell and Emma continued on. "Because I'm eating all of this right here right now."

"You know I hate to deny you, Swan, but you will get sick off a whole bowl of this." Emma pretended to consider if it was worth the risk but finally caved, knowing he was right. The last thing she needed was any sort of food poisoning, especially from cookies this good.

"Fine. But when you bake them I call dibs on all of them."

"I can't even procure one from you, love?"

Killian's hands were on her in that moment and his voice had dipped low to that tone that always made her pulse pick up. Damn him and his constant underlying hotness. Killian might claim she was the one with all the influence in this relationship but he was dead wrong. No one else had a sway over her emotions and her wants like he did.

"I could probably be convinced. But it would take a really good argument."

"There are so many things I could say to that, it's impossible to choose."

Emma knew he was right. She'd set herself up for a host of innuendo but instead of waiting around to see what he'd decide on, she dipped her finger into the batter and offered him some, watching the flare of desire that darkened his eyes as she did.

"You'd surrender so soon?" Emma chuckled at his cocky grin.

"If you taste this you'll understand why I will be so headstrong about hogging it all in cookie form. How do you do that by the way?"

"Do what?"

"Make something so good without even tasting it?"

"Instinct. And a good amount of luck."

Emma was about to reply to that when he slowly and seductively licked off the dough that she'd been holding out for him. It flooded her system with a startling sense of hunger and it was impossible not to imagine that skilled tongue of his doing a variety of other things all designed to bring her pleasure. Yet before she could convince him to engage in those kinds of fantasies, Emma watched as Killian's own clear arousal waivered slightly.

"What's wrong?"

"I still get the sense that there's something not quite right."

"No way! Absolutely not!" Emma took the bowl right from under him and the piece of paper that he'd written all the exact measurements on. He reached for them but she retreated, maintaining distance so he couldn't get them back.

"Emma -,"

"Nope. These are perfect. Like perfect perfect, and I am not letting you mess with them anymore. You want to make more cookies? Go for it. But these are going to win me those bragging rights. Hands down, no way around it." Killian looked sincerely in need of reassurance but her defiance and her protectiveness over the bowl eventually thawed away his doubt bringing back that slightly lopsided smile she loved.

"You're certain?" Emma made a motion to cross her heart and his grin widened.

"Killian, I swear this right here is the holiday cookie to beat all other holiday cookies." Killian moved forward and took a bit more from the bowl to taste, considering in a serious and professional way. Somehow his intensity, even if it was crazy, only made her love him more.

"I think you're right. But maybe I should just -," Emma bit back a groan and sprung into action, putting the bowl back on the counter and bringing her hand to his chest as she stepped into his arms.

"No buts. This is seriously a miracle of a cookie. It's a cookie to share with our kids, and they'll tell their kids and so on and so forth until someone finally sells out and capitalizes on the secret formula so the whole world can try them. These are big money, household name cookies, Killian, trust me."

Emma expected maybe a touch more resistance on Killian's end or perhaps a caving into laughter, but not this curious look that was simultaneously passionate and hopeful. His hands came to hold her during her profession and they held onto her tight but it was his eyes that held her spellbound. The blue was unwavering and captivating but still she was at a loss.

"What, what did I say?"

"You said our kids." His voice rumbled out the words and it took her a second to understand him but when she did she started to panic.

Oh fuck!

The charming reassurances that Emma was inundating him with were almost lost as soon as she said those fateful words: 'our kids.' It was nearly impossible to make out the light hearted humor Emma put forth after that, not when she'd shifted the world around him so profoundly with just one hint of future togetherness.

Whether Emma meant to let slip her idea them having kids together or not she'd done it, and for someone like Killian who was looking for a sign that the future he wanted could come sooner than might be deemed strictly customary, this was a fantastic moment. His heart hammered loudly in his ears and his whole body was filled with a need to hear her say it again.

"What, what did I say?"

Emma looked concerned as if she'd done something wrong when it was in fact the opposite. Nothing had ever felt more right, other than perhaps the moment when she said 'I love you' to him and he got the chance to express his feelings in return. The knowledge that she had imagined a future for them, one with kids and a family… it fed this part of Killian that for so long went unnourished.

He'd been a workaholic chef with little ambition outside of his professional life until the day he met Emma. Now his dreams were spanning a whole host of areas, all because of this woman and her unsuspected ability to completely consume him.

Emma made everything better; she made things truly worth doing and seeing and experiencing. For the first time in Killian's life there was a real payoff for his actions, a sense of happiness more than mere achievement. He was only just getting used to that power that she wielded, and with this small, unanticipated statement she'd demonstrated all over again just how important she was to him and to his hopes for a fully happy future.

"You said our kids."

Killian barely recognized his voice as he said the words, but if anything could pull him from the fog of his own pleasure it was Emma's face. For the first time in a long time he saw a real fear in her eyes. She was panicking, second-guessing this beautiful gift she'd just given him and he couldn't have that. So instead of letting her stew in her worry, he closed the distance between them and kissed her surely and without any hesitation.

Before either of them could begin to doubt the merits of this moment, Emma melted into his embrace and then started to silently plead for more. She pulled him closer, arching into him and meeting him beat by beat in their kiss. Whatever anxieties she had she was transferring into this and he would take every ounce of it and wipe it away with his love for her. Killian was determined to make her see that he wanted this, that he wanted her, with every fiber of his being and more.

When they finally parted and their breathing came out ragged from the exertion and the continued need between them, Killian had a choice to make. Take her now and dive headfirst into showing her how he felt, or appeal to her with words that might try and convince her that this was exactly right. They weren't on the same trajectory as ordinary people. How could they be when what they'd found together was in a realm all it's own?

With his mind made up, Killian brushed a strand of her hair that had slipped between them behind her ear, taking a moment to let every last shiver of anticipation and flush against her creamy skin take hold of him. He was a man dedicated to details in his work, but his study of Emma made all of that seem tame. He'd never know enough about what made his lovely Swan the way she was, but he was trying and he'd try every day for the rest of his life if she only gave him the chance.

"I love you."

His words made Emma close her eyes and he could see the relief in the action but he needed more. He wanted to see her in full when he told her everything and so he waited for her eyes to pop open again as his thumb traced the corner of her mouth. When she complied with his silent entreaty he soldiered on.

"There is nothing in my life that has ever made more sense to me than this, Emma. What we have, what I've found by knowing you and loving you, it so far surpasses anything else in the world to me. I haven't wanted to frighten you off, but I can't see a future without you Emma, and frankly I don't want to. I want to make plans, I want to find our way to that, and I want to get there sooner rather than later."

"You do?" Emma's question was squeaked out with a strange inflection but Killian only smiled.

"Aye, love. So the only question is did you mean it, Emma?" She blinked at him before replying with a joke in that way that spoke to her feistiness and strength all at once.

"You mean about the cookies? Yeah I meant it. They're sublime. You could have people saying 'Betty Crocker who?' that's how good they are."

Killian couldn't fight off the want to kiss her so he gave in instead but he denied them both the more they were after. Her hands curled into his shirt in tight fists holding him to her but still he pulled back, wanting to hear once and for all what she wanted.

"I think about it a lot."

"Think about what, love?"

"The future, a future with me and you together I mean." Killian hummed out a sound of approval that was natural and instinctive almost like a purr.

"And what does this future look like, Emma?" She smiled and now it was her turn to raise her hand to cup his cheek. She searched his eyes and Killian knew she could see him in full. He wasn't trying to hide but there was a moment of connection where he knew that Emma had everything and that she finally understood.

"It's happy because we're together, always."

That last word sealed everything for Killian. He could stand there and wait until she was ready to completely reiterate the sentiment of them having kids or getting married, but instead he drew a different path, one that would settle even a little bit of this simmering, coiling pressure inside of him. He needed to ground himself in Emma, in every part of this thing between them, and the easiest way to do that was simple – by getting her in bed and making love to her.

Killian began maneuvering them out of the kitchen only for Emma to pull back. He was about to question her reluctance to go when she reminded him of one rather important detail.

"Aren't you forgetting something?" Killian wracked his brain trying to think of anything that he could possibly forget. He had Emma and that was all that mattered in the end. Then it hit him when her eyes traced back to the kitchen counter. The cookies. Right.

"What would I do without you, Swan?" Emma blushed at the off the cuff comment and as soon as Killian put the dough back in the fridge he took her hand again. "Truth is I have no intention of finding out."

Her smile returned at that and soon enough they'd made their way back upstairs, both of them eager to reduce the space between them. Somehow they'd spent all day together and it still didn't feel like enough to Killian. He'd been craving such domestic displays with Emma since they first met and now that they were here he was nothing but glad for it.

All through the morning and the afternoon Killian experimented with these recipes hoping to gain Emma's favor but as time went on he found himself increasingly distracted by Emma's sense of perfect calm. Killian realized as he was baking that he'd never seen her truly worried in all their time together, never seen her close to running despite the past she described to him. And any time their eyes met throughout the day it was all smiles and easy affection between them. In short today had been bloody perfect and Killian was willing to do anything to keep this going.

"I know that look."

Emma's comment pulled Killian from his racing thoughts. Her sultry tone set his skin tingling and though he had his hands on her and held her close he still needed more. He set about stripping away some of the clothes between them and it was a difficult task to not only take in her radiance but to continue this bit of banter as well.

"I've a look about me, do I?" she smiled and it packed all the punch of all her thoughtful, warm looks that she sent his way.

"Mhmm. One that tells me you're in a very giving mood."

Killian had a witty reply in mind but it didn't come out as controlled as he hoped thanks to Emma moving her hand down his chest and then toying with the button of his jeans and unzipping his fly with deft precision. The suspense was killing him and yet he lived for these moments with Emma where she took the reins with ease.

"Well it is that time of year, love."

Emma chuckled at the joke, no doubt taking in the way she'd swayed things into her territory now. She removed the final scraps of clothing that remained on her body, revealing every last piece of her to his eyes and it was work not to let his jaw drop. Every damn time she took his breath away and every time they came together he wondered how he'd ever gotten this lucky.

"So what? Come December 26th everything changes? You're suddenly a selfish guy all of a sudden?" Killian growled at the thought before maneuvering Emma to the bed.

"Not a chance."

Emma laughed again but it turned into a thready sigh as Killian pressed kisses to her lips down her jaw and to her neck. He nipped at the spots that he knew always got her flustered, feeling her groan wash over him as she let her honest reactions come out. Nothing could be more beautiful than Emma telling him what she wanted, and he followed her vocal but nonverbal instructions to a t with a slow, steady, languid pace.

The easiest way to making Emma lose her mind was building up the tension and he'd mastered in the past two months every way to do that. He moved his mouth from her neck down her collar and lower to her breasts. The keening sound she made when he bit just above her aching bud was music to his ears and made all the better by the way her breath caught as he sucked a nipple into his mouth. His hand made sure her other breast was never wanting, tending to it with the same variation of rough and achingly gentle until Emma began to writhe under him.

"Killian."

His name was said in a way that he had come to understand. She was growing impatient, and as much as part of her loved that sensation, Emma also craved satisfaction just as much as Killian wanted to give it to her. Her frenzied panting and sighs of sexual frustration had been clawing at him right along with her hands and his body was tight with a need to give her more even if he loved to leave them both desperately on the edge.

"Yes, love?"

"I need -,"

Emma's thoughts unraveled as one of Killian's hands moved down her body. Her legs opened wider and his thumb found her clit pulling a hum of gratification from her chest. Her eyes closed but Killian didn't want that. He wanted to watch every last part of her when she came apart and her eyes were the most expressive element of that every time.

"What do you need, Emma?" Her eyes opened and she smiled, a tint of pink clinging to her as she did and her lips parting ever so slightly.

"More."

That was enough for Killian and he worked to grant her wish, using one finger and then another to fill her sex until her hips bucked against him. She was inching closer and closer to a climax, but Killian wasn't quite ready to give it to her yet. He removed his fingers and slowed the swirl of pressure against her clit, knowing it would curb the rising tide of desire in her.

He kissed down her body, making a mental note of her now taut abdomen where someday, hopefully soon, she'd swell to carry their child. The thought alone made him growl again and he watched as Emma jumped, not from fear, but from pure adrenaline. Just as it was his bodily instinct to make the sound, it was Emma's to react and to revel in the fact that very soon he'd give her exactly what he wanted.

"Killian?" He looked back up into her eyes from his place between her legs, seeing something there beyond just need but before he could ask she spoke her mind. "I love you."

Damn it all to hell! How was he supposed to go slow when she said things like that? The answer was he bloody well couldn't. So without hesitation he pressed a kiss to her still sensitive flesh. He barely made contact and she was spilling over into release, calling his name as she went, but Killian wasn't deterred in anyway. He lapped up every part of her climax and then gave her only the briefest of moments to regain her breath before setting back to bring her more pleasure.

As her hands came to intertwine in his hair, holding him closer, Killian watched Emma take every suck and tease and stroke of his tongue within her and at her clit. She was lost to the feeling and completely, utterly open to him. He couldn't articulate the completion that brought him in turn. To know he had her trust and her love was everything and the icing on top was watching her fly high once again by his ministrations.

Killian kissed his way back up her body until finally he was back with Emma again. She looked happy and sated but a flicker came to her eyes in an instant that changed everything. One second Killian was above her, the next she'd flipped their positions to take control once more.

"Did my way leave you unsatisfied, love?" Emma rolled her eyes.

"Yeah that's definitely the problem." The sarcasm was tangible in her tone and Killian thought to laugh until her hand moved down the flat planes of his stomach and lower to fist his cock. Fuck that felt good. "Just thought I should remind you that the giving always goes both ways with us."

He hadn't needed any reminder about the superior abilities Emma had to drive him mad with lust, but she showed him all the same, first with her hand and then with a teasing display from her mouth. He was begging by the end for her to have mercy because much as he'd love to find his pleasure like that, he wanted to find it with Emma more.

And they did find it of course. It was impossible not to given the way things were when they came together. Hot wasn't the right word. This was raw passion, a rampant fire, electricity so striking it couldn't be denied. Nothing had ever felt this good and it was entirely thanks to Emma despite what she might say to the contrary. No one, not even his Swan herself, could convince Killian otherwise. This bliss could only ever come from her.

"Let go, Killian." Killian shook his head and ground his teeth together, staving off until Emma was with him too. Only when she'd shattered did he do the same and when the moment came it was just as blindingly brilliant as all the others.

When they were spent from the exertion and lazing in that perfect sense of peace that came in the aftermath of such displays, Emma's hand wandered over to take Killian's. Their fingers intertwined easily and the feeling that they were truly one remained. Killian pressed a kiss to the top of her hand and then held hers over his heart as he made her a solemn vow he would never break.

"I promise you, Emma, that the always that you want we can have. I'm not going anywhere ever. Not if you aren't with me. I'll stay right here and fight for that future you want no matter what it takes." Emma sighed happily, moving closer to him as her fingertips brushed against his chest, light as a feather.

"I don't think it will take much fighting do you? It's not like this is one of those fairytales where the guy slays a dragon to get the girl." Killian smiled at her playfulness and kissed the crown of her head, closing his eyes and taking in the lingering scent of vanilla and cinnamon that remained with her.

"If it came down to it I'm not sure which of us would be more qualified in that kind of battle. I highly suspect you might be the dragon-slayer in this duo." Emma giggled against him, sending a perfect flutter of vibration surging through him. "But even if we haven't trials like the ones in storybooks, I want you to know that I won't let anything stand in our way."

"I know you won't. I know we won't. There's no reason for you to go about fighting for us alone. Not when we're a team."

Killian loved the sound of that but in that moment he decided he needed that term to change. A team they may always be, but what he truly wanted was for them to be a family. In his heart Emma already was the most important person in his world, but now he had to make that official. He wanted to make her his partner and his wife and he was fairly certain he had the exact means to do that if he could only wait a tiny while longer.

Post-Note: God bless this fic for letting me just throw more gratuitous fluff around and intermingle it with holiday festivities. Seriously, I am so happy to get this outlet for Christmas stuff and since the story will be shorter (we have one last chapter before the epilogue), I get to move quickly which is always so fun. Anyway, I thank you all for reading, I hope that you guys enjoyed, and that you all have a lovely rest of your weekend!
