Author's Note: Okay, so this story is pretty much the result of a review left by the inimitable DLK. He basically insinuated in his review to Sarah vs. The Rope-a-Dope: Chapter 2 (you should all read that story if you haven't already) that I could make tic-tac-toe seem interesting. Well, my ego liked that challenge, and since my ego dictates all of my actions, I decided to give it a try. This story, this serial, this chapter, is a result. But it's not just this piece here. I decided to take the concept of every day, supremely boring activities, and give them a smutty, Charah twist. So this is the first of many chapters in this story, all inter-related in some way, but can be read separately if you want, and all take place in the same universe as Chuck vs. The Crane and Sarah vs. The Rope-a-Dope. If that makes sense to you, then you are smarter than me.

Thanks must go to the aforementioned DLK, who this story is kind of dedicated to since he pretty much inspired it. And to DD for her encouragement and beta. Thanks!

"I'm never letting you pick our date night activity ever again."

"Are you trying to tell me you're not having fun?"

"That's exactly what I'm saying."

"That's just because you're losing," Chuck said smugly.

Sarah threw her pencil down on the table in disgust. "This is the stupidest game ever. Nobody can ever win!"

"Er…I do believe I have four victories to your zero."

"Those don't count!" Sarah objected and glared at her boyfriend. "You cheated!"

"How did I cheat?"

"You kept…touching my…thigh," Sarah said lamely. She knew she sounded ridiculous. She was supposed to be a trained spy, what did it say about her that she could be distracted so easily? "It wasn't fair," she pouted.

"I don't think I've seen anybody lose at tic-tac-toe since I was like four."

"You ass," Sarah said with an incredulous laugh. "Like I said, you cheated. So it totally doesn't count."

"I don't think there is a no touching rule in the official tic-tac-toe rulebook."

"There is no rulebook, and if there was, that would be in there!" Sarah glared at Chuck half-heartedly, poking him in the chest. It was starting to get really hard not to smile, especially with the way Chuck was currently looking at her.

"Fine," Chuck said. He crossed his arms and sat back. "Then stop smiling."

"I'm not smiling!"

She was, in fact, now smiling. It wasn't really her fault. Most of the time these days, she couldn't be around Chuck and not smile. And he was grinning at her just so adorably it was impossible not to.

"What do you want to do instead?" he asked with his usual open and innocent face. "Would you…" he started to say, but she cut him off with a hand over his mouth.

"Don't you dare say it."

Tentatively she pulled her hand away, giving him a very stern look.

It had no effect. He cleared his throat slightly and said in a mechanical voice, "Would you like to play a game?"

Sarah groaned and buried her face in her hands as Chuck chuckled beside her. "You can be such a nerd sometimes, you know that?"

Chuck sobered up and she watched him struggle to adopt a straight face. "Sorry, sorry," he said, the corners of his mouth constantly upturning and then relaxing as he fought the urge to smile. "What do you really want to do?"

Stop playing this stupid game and have sex. That was the first thought that popped into her head. Have sex repeatedly was the second.

It frustrated her to no end that she was never sure if Chuck ever had the same thoughts about her. Did he not want her as much as she constantly wanted him?

"I don't know, watch a movie, go to the Pier, go dancing, scrapbook, anything is better than this dumb game," she said with a frustrated sigh.

Chuck had already told her twice that he didn't want a relationship built solely on sex. That just because they were together now for real didn't mean he still didn't want to take her on actual dates like he had when they had merely been cover dating. He wanted to romance her, treat her right, and give her the kind of things she deserved. It was unbelievably sweet and every time he said it or showed her how much he meant it, she melted a little more inside. But honestly, she would be perfectly content if they stayed locked inside his bedroom for the duration of what few nights they got free to themselves.

And it had been a week since they last had sex. She was starting to get restless.

She had never been big on going out. Not with Chuck, at least. She liked having him all to herself. She liked not having to share him with the world, especially now when she literally was sharing him with the world. Tomorrow they had another mission. Tomorrow, she would have to share him with Beckman and the CIA and the Ring and who knew what else. Tonight, she just wanted him and nothing more.

Well, him and their bed.

"Hmmm…well, I would be open to scrapbooking," Chuck said with a contemplative look on his face.

She almost hit him. He really looked like he was considering it. Seriously? There was no way he would actually rather scrapbook then have sex with her. No way. Was there?

"Chuck, can't we just skip ahead to the inevitable conclusion of tonight's activities?" She tried not to sound too desperate, but she really wanted to move things to the bedroom and she couldn't help the note of pleading in her voice.

"Whoa there, let's not get ahead of ourselves," he said with an infuriating smile on his face. "We still have at least another sheet of games to finish," he added, picking up said sheet of paper and waving it in front of her face. That was when she saw it in his eyes. His eyes had always been open to her and she prided herself on her ability to read them. And right now his eyes were full of mischief. He was doing this on purpose. The bastard was playing hard to get on purpose!

She glared at him and stood up, placing both hands palms down on the tabletop and leaning forward so that she loomed over him. As he looked up at her with those dancing brown eyes of his, she contemplated grabbing his shirt and yanking him up onto the table. Then she would force him to help her test whether IKEA had been correct in saying the load bearing weight of the table was 400 pounds. As the fantasy ran through her mind, she shook her head slightly to make the images go away. She needed to concentrate here!

The sex could come later, like within the next five minutes later. But she still needed to concentrate so she could force Chuck to get with the program and stop stalling. She knew she was being predictable, that Chuck was probably only doing this because of how crazy it made her, but at the moment she just didn't care.

"You, Mr. Bartowski, are nothing more than a big tease."

Chuck shrugged his shoulders very nonchalantly and smirked up at her. "Well, somebody has to be," he said. "We can't all be as easy as you are, Miss Walker."

She gaped at him in stunned surprise, the delay more than enough time for Chuck to scramble out of his chair and move to the other end of the table. With the entire length of the table between them, he seemed brave enough to give her a wicked look of satisfaction.

"Oh you are so dead," Sarah hissed. She feinted left and went right, but Chuck either knew her too well or she was telegraphing her moves because he darted around to the opposite side of the table with a hearty laugh. The only thing she had accomplished was them switching sides.

He held up his hands in a gesture of peace, and there was a confident smile on his face. "But if I'm dead, who will you…" he paused and cocked his head to the side, his smile transforming into a smirk, "how did you put it? Oh yes, who will you spend the conclusion of tonight's activities with?"

"I could find somebody!" she blurted. It was the emptiest threat she had ever made in her life and they both knew it.

Chuck just look pleased with himself.

"I could!" she repeated stubbornly. When she saw how smug he was still looking, she growled out, "Don't get cocky."

"I thought getting cocky was exactly what you wanted from me right now?"

Sarah groaned loudly and rolled her eyes. "Oh God, Chuck, that was terrible. Even for you."

Chuck just shrugged his shoulders at her. He appeared completely unapologetic, but that's what she loved about him. Only he could say a line like that and have her think it was the corniest, most ridiculous line ever and yet still find him adorable.

She needed to get back on track. She growled slightly and slowly started to edge her way around the table. She was stalking her prey, moving with the sinewy grace of a panther. He wouldn't be able to run from her forever. "You picked the most boring game in the world so that you could tease me. And then," she just couldn't get over this, "you cheated! Who cheats at tic-tac-toe?"

"I so didn't cheat. I merely used what I could to get an edge over my opponent. You taught me that."

"But you did pick that damn game just to drive me crazy," she insisted stubbornly. This was stupid. They were arguing over tic-tac-toe. This was really what he wanted to devote their evening to?

"I have no idea what you're talking about, Sarah," he said, and he almost sounded completely sincere. But his eyes gave him away again, as they always did, and they were dancing with amusement. He still had that damn smile on his face and God it was seriously starting to affect her. Her blood was pumping in her veins, warming her so that she felt heated, like she was wearing a sweater in a 90 degree room, and her thought process began to muddle. Damn that smile. Damn him. He knew exactly what he was doing to her.

Giving in to him (even though she had made the first move, it was still her giving in, because she just couldn't take it anymore) that night in Castle was the worst mistake she had ever made. Oh she managed to put on an air of professionalism while out in the world, she managed to control herself (just barely sometimes, unfortunately), but when it was just the two of them, she became some kind of moony-eyed teenager. She would literally do just about anything he wanted. And to make matters worse, he knew it too. It was typical of their relationship, typical of how he tended to do the exact opposite of what she claimed she wanted him to do (while secretly doing exactly what she wanted him to do); the one time she desperately wished her perpetually clueless and oblivious boyfriend would miss something, meant that of course it was the one time he wouldn't. He knew what kind of power he had over her. It was disgusting. She was disgusted with herself.

And with his now cocky, confident smirk that sent waves of pulsing heat directly into her groin, she honestly didn't give a fuck. Because that night in Castle was easily the best mistake she'd ever made too. Hell, she couldn't even call it a mistake. She wished she could, she really did, but he was the best thing to ever happen to her.

"When I catch you, I'm going to make you eat those words," Sarah threatened, still trying to get close enough to Chuck to pounce.

His eyes widened slightly but then he very slowly licked his lips. "As long as I get to eat something else, I'm okay with that." Then he gave her the Bartowski eye brow dance.

Yeah, so like, her entire thought process? Completely obliterated.

"Chuck…bedroom. Now," she growled out.

Chuck blanched at her tone and some of his cockiness disappeared. Maybe he was finally starting to realize how completely serious she was. If he didn't get his ass in his bedroom soon, she'd drag him in there herself.

"Now, Chuck!"

"Sarah…let's talk about this…" he said, backing up slowly until his back was against a wall. There was a slightly wild, wide-eyed look on his face and in another situation, it would almost be comical. But this was not funny. She wanted her boyfriend and she wanted him now.

Sarah continued to stalk her prey. "Talk? All we've been doing is talking. I get one night out of the week, if I'm lucky, where I get you all to myself. The last thing I want to do is talk. There are much better uses for your mouth than that."

To her surprise and incredible relief, Chuck was not trying to avoid her anymore. He just stood against the wall, his eyes searching for something, maybe an escape route, before they finally settled on her.

She stepped up to him and had to take a deep breath to get herself under control.

"What do you want then?" Chuck asked.

Sarah moved even closer, trailing her hand slowly up his arm until her fingers were buried in his hair. He let out a quiet sigh and she saw his body relax. She leaned up and smiled as she watched his eyes close, but she bypassed his lips and instead went straight to his ear. She whispered huskily, "I do believe you said you wanted something to eat."

She pulled away from him and she heard him let out a shaky breath, his eyes slowly opening. They were very dark, and he looked as if in a daze. "That's…what…you want?" he stuttered out slowly.

She just bit her bottom lip and nodded her head once.

And then he kissed her.

Her last fleeting thought before she lost herself to the sensation of his lips on hers was Finally.

There were very few things that turned her on more than when Chuck was confident, assertive, and in charge, especially when he was those things in the bedroom. There had literally been dozens of occasions since they started sleeping together where she had barely managed to stop herself from tearing all his clothes off and making him forget his own name while on a mission. She'd had those urges before they got together, of course, but at least now she had the ability to act on them, even if she couldn't quite do so in as timely a matter as she would like.

Right now was no different.

He had her pinned to the bed, one large hand holding her arms together above her head. She could have easily broken free if she wanted to, but that was pretty much the last thing she wanted right now; especially not as long as Chuck continued to pepper light, warm kisses along her neck and jaw. His other hand was slowly moving her shirt up her torso, exposing her trembling stomach to the suddenly stifling air of his bedroom.

His fingers brushed across her rippling skin and she sucked in a breath at the touch. He placed his palm in the center of her stomach and just held it there. It was warm, comforting, it made her feel safe and protected. Chuck always made her feel that way.

Then the hand began to move upwards, toward her breasts, and she felt her stomach clench in anticipation at Chuck finally touching her in a way she desperately needed at the moment. She'd always had sensitive nipples, which she had helped Chuck discover early on in their sexual relationship, and there was enough of the typical male inside her boyfriend that her breasts were always one of the first destinations for his wandering hands. That was perfectly fine with her, and she often encouraged him to do so.

But to her lament, the tips of his fingernails only briefly dipped under the cups of her bra and dragged against the soft skin of her breasts. The action made her whole body shiver, starting from her head and moving down to her toes, which clenched briefly, and caused her to moan quietly. But it was not nearly enough for her and she let out a needy whimper when Chuck moved his hand away.

This was not at all going to script. He was supposed to continue touching her, was supposed to pull off her top, unhook her bra, and feel her up for a few minutes. That's what she wanted. Or at least that's what she thought she wanted until the hand on her chest trailed down to play with the button of her jeans. Okay, so this was an acceptable deviation from the plan.

"Chuck," she said breathlessly.

He just gave her a gentle smile and kissed her. His warm lips settled comfortably on hers and they exchanged a series of soft, slow, lingering kisses. When Chuck's tongue languidly entered her mouth and started a dance with her tongue, she made a contented noise and relaxed completely into their bed. She forgot all about the hand skimming the waistband of her jeans, occasionally dipping an inch or two underneath the fabric before darting back out to trail across her lower abdomen. She forgot about everything but Chuck's lips and his mouth. It was her whole world for what felt like forever. She only wished it really was forever.

When Chuck finally pulled away, she pouted. "Noooo," she whined quietly and fought half-heartedly to free a hand so she could force his mouth back where it belonged, but he simply pressed down harder on her wrists and she soon gave up.

He beamed at her, his eyes warm and full of affection, and then he said, "Promise that you'll behave?"

She gave him one of her most sultry and smoldering looks and purred silkily, "I thought you liked it when I misbehaved?"

Chuck completely froze after that, like his brain needed time to process her words and restart, but once it did, he gave her a goofy grin. "I do, but I really wanted to finish our game."

"Chuck," Sarah huffed in sudden exasperation. "We're a little beyond that, don't you think?"

Chuck shook his head, the happiness gradually disappearing from his face to be replaced by a look of concentration. He deftly undid the button of her jeans with his free hand and slowly pulled the zipper down. Sarah sighed in frustrated anticipation and had to bite her bottom lip to stop herself from wiggling her hips insistently.

Chuck suddenly left her hands free and grabbed her jeans with both hands. She eagerly lifted her ass off the bed and he quickly pulled them off her body. He immediately leaned down and placed a kiss along her inner thigh, which caused her to giggle and sigh nearly simultaneously.

Finally, they were getting somewhere.

Chuck's hands slid torturously slow up her thighs to grab the waistband of her panties but instead of pulling them down like she was yelling loudly in her mind for him to do, he simply stopped and rested his chin on her hip. He looked up at her with big eyes and asked, "So are you ready to continue our game?"

"No, Chuck, I don't want to play the stupid game anymore," she gritted out and stared down at Chuck's smiling face with what she hoped was a dangerous look in her eyes. It probably would have helped if she were wearing pants. "I want you to…oh!" she exclaimed. Her eyes widened in sudden surprise, as a finger briefly slid down her covered sex.

Chuck smiled excitedly, his finger just resting on the apex of her thigh. "I see you're finally getting in the spirit of things. That's great!" He moved his finger and repeated the same motion from before, and this time her eyes fluttered close. "I'll be X's and you can be O's."

Chuck mercifully pulled her panties down her legs and she immediately spread her legs wide enough for him to settle between them. "I'll go first," Chuck said.

Chuck's index finger very slowly skimmed along her outer folds, making her breathing speed up. But it was not nearly enough for her. She rocked forward and let out a long, shuddering breath as Chuck's finger easily slid all the way inside of her up to the knuckle. "God, finally," she hissed between clenched teeth.

But Chuck apparently didn't share her sentiments as he placed a stilling hand on her waist and held her in place. He withdrew his finger and clucked at her in disapproval. "Hey, it's not your turn yet."

"Chuuuck," she whined. She was tired of stupid games. She just wanted him, not some freaking game.

Chuck nuzzled the inside of her inner right thigh, pressing gentle kisses along the highly sensitive skin. She sighed, which quickly transformed into a quiet moan, and could not stop her body from tensing up. Every touch of his lips to her skin was like a mini jolt of electricity, sending heat racing up and down her body, tensing her muscles, and increasing the pressure in her abdomen. She felt like if she didn't get relief soon she would burst.

"Okay, your turn now," Chuck said in a low, husky voice.

"What?" she asked in a daze. She had no idea what he was talking about, she could barely concentrate on anything but the warm breath cascading across her.

Then Chuck leaned forward abruptly and licked along her folds in one slow, hard pull with his tongue. Sarah gasped and moaned, "Ohhhhh…oh God, Chuck." Then Chuck repeated the motion several times over and she found herself devolving into babbling nonsense.

Just as quickly as Chuck had started, he stopped, causing the building crescendo inside of her to level into a constant ache. "Chuck," she said with obvious strain. "Please don't stop," she begged.

"But it's my turn now." Chuck said with a cheeky grin before he suddenly thrust two fingers inside of her. They began to move in and out at a steady pace and she almost immediately started to rock against his hand. Oh this was so much better.

"Faster," she urged, her eyes screwing shut and both her hands grabbing onto the sheets of their bed with tightfisted grips.

"Time to go for the center square," Chuck murmured and then she felt his tongue join his fingers.

"Oh…" was all she could manage to articulate.

His lips wrapped around her clit and he lavished it with his tongue. She came hard then, the orgasm rushing through her in waves, like a pulsar in the night sky.

It took her over a minute before she felt calm enough to breathe evenly and speak. "Come here," she said and reached down with her hands to pull him up.

He settled on top of her easily, his weight a comfort, and she wrapped her arms around him, hugging him to her body. She kissed him then, slow and soft. "Thank you."

Chuck grinned and said, "Best game of tic-tac-toe ever."

She rolled her eyes and kissed him again.

So what is next for our horny spies? I got three words for you: Watching paint dry.
