An: Thank you for the reviews, I honestly did not think this would receive much positive feedback, but look I was wrong! As I promised, I have come out with another chapter. To be perfectly clear, this fic may be smut when it's all said and done, but it is smut with heart, character development, and some semblance of an ongoing plot. So if all you want is hardcore, mindless sex scenes, this won't be the story for you. Oh and the timeline is fucked. So like in the show, ignore it, alright. Ignore it and just...just come.

Also, I could not have done this without my beta, Yumajii! Thank you!

R&R and Enjoy!

Chapter Two: Favorite Fix

"When I come down, I can't replace the feeling of falling to my knees. And i'm sweatin' 'cause i'm fiendin'. I need it. You know that in the end (You're my favorite). I'll relapse again. (You're my favorite). I'm down to my tricks, you're my favorite fix," -Favorite Fix, Artist Vs Poet.

To put it mildly, Zac was having a bad day.

He appeared before several cameras. Their lenses tightened in focus at the slightest movement; those operating them remained poised and ready for the scene to unfold. A single circle of stringent yellow light, thrown by the ceiling overhead, lay upon Zac's face like a beacon trying to identify a convict during a prison breakout. Numerous pairs of eyes were trained on him and waited in quiet anticipation.

What should have transpired next was supposed to be second nature to the thirty-year old actor. His brain insisted for him to move but his body firmly resisted. He stood unnaturally still, the same way he'd sometimes come out of a nightmare as a child: paralyzed with fright, totally disorientated, not sure of where he was, let alone what he was doing.

Something was causing both his hands and feet to tingle uncontrollably. He felt like he had been kicked repeatedly in the gut; a hellacious migraine nearly bringing him to his knees while he struggled to remain upright, conscious. Ugh, I'm going to be sick, he thought, eyes watering. Stupid ultimatum. Why did I have to agree to it?

An elbow nudged gently at his side and brought him out from his musings. Zac blinked furiously, glancing sideways to find Josh Gomez looking at him strangely. Zac opened his mouth to speak. Before he could, another voice boomed: "OK, CUT!"

Suddenly all of the cameras shut off. The lights dimmed and the cast and crew of Chuck began milling around the Pasadena Church as they began (once again) to reset for another take.

"Dude, what's wrong with you?" asked Josh during the commotion. "You've been 'off' today."

They turned and faced each other. Both were wearing tuxedos, dressed as the best-man and the groom respectively. Where Josh appeared well-groomed and looking sharp, Zac was the exact opposite. Josh noticed this and furrowed his brows. Someone from the art department then approached both of them, applying a layer of make-up onto Zac's pale complexion, and moved to Josh, where she pampered him as well. Left alone once more, Zac shrugged helplessly. "It's complicated," he said.

It's complicated. That was a vague response. But even so, it described Zac's current situation perfectly. A week ago, he did not know the meaning of complicated. It was not until the moment he kissed Yvonne that life took a rather unexpected turn. Not only was he constantly lying to preserve his relationship with his female co-star, but he had to contend with Chuck's nearing cancellation as well as his decision to quit smoking. The symptoms of his withdrawal were particularly brutal—both mental and physical, he felt as though each breath could be his last. He had also been suffering from frequent bouts of insomnia since the night he and Yvonne began their love affair.

Since then, Zac had been on edge. He felt like a junkie searching for his next fix; it was pathetic and debilitating, not to mention completely exhausting. The saddest part was that he could not explain any of this to Josh, or hell, anyone else for that matter. Zac knew that if he continued to keept his and Yvonne's dirty little secret like his own personal burden, it'd no doubt destroy them both.

Josh was unconvinced by his friend's ambiguity. "Whatever you say," he told Zac warily, "but you look like shit."

"—what's up with the two of you?" Robert Duncan McNeill, the director of the episode shouted as he made a beeline straight for Zac and Josh. "Guys, we've been working on this one scene for almost thirty minutes and I am seeing no improvement." He addressed Zac specifically, "You look like shit, are you sick?"

As Zac was about to shake his head and deny his accusations, Josh replied for him. "He needs a break, Robert. I think all of us do."

The director sighed, "Fine. Let's take a fifteen minute break and then be prepared to act your asses off for take forty-five, alright?

Zac shot the bearded man an appreciative smile, "Thanks guys, I think I just need a breath of fresh air and I'll be good to go."He told both men, slapping the older of the two on the shoulder before heading for the church's entrance.

"You better be rehearsing, Zac!" Robert yelled across the chapel, "I don't want us to be here all night!"

With a quick thumbs-up over his head, Zac ducked out of the building. Robert and Josh watched him disappear behind double doors and then exchanged confused looks.

"Do I want to know what's really going on with him?" The director asked flatly.

Josh half-smiled. "Well he did say it was complicated."

As time began to tick down slowly, Zachary carefully assessed his surroundings while walking across the cobblestone path that'd lead him to the parking lot several yards away. Don't bring attention to yourself, he told himeslf as he passed an elderly couple. He smiled politely with a curt nod; the last thing you want right now is to be somehow distracted.

The plan was simple: Zac would go to his car and grab the pack of Marlboros he kept stashed in the overhead compartment in case of such an emergency. He'd make himself scarce; light up a quick smoke and relax until he had to resume filming. Zac was positive that it would behoove the entire Chuck crew if he could manage to sneak just one cigarette passed Yvonne.

Once he traveled about half-way down the path, (with his car now in plain sight) Zac came to a bench table where three familiar faces sat, talking animatedly while enjoying their lunch together. He tried avoiding them, keeping his head down as he sped up his pace into a brisk walk. But unbeknownst to him, he had been caught before he could make one more step towards his saving grace.

"Hey, Zac!" a female voice called. "Where are you going in such a hurry?"

He briefly considered the idea of ignoring her and going on about his business. But of course, the nagging voice inside of his head (admonishing him for being selfish and rude) forced him against it. Zac let out a bitter sigh and turned around, feigning a smile at the small group of women.

It was Sarah Lancaster who had spoken to him. She was waving him over to come join them. Zac was close to just making a break for it, but his feet betrayed him and ended up dragging his body away from the silver Nissan.

At the table next to Sarah was Mekenna Melvin. The young actress chanced a quick glance at Zac, smiled shyly and then returned to picking at her half-eaten salad. Across from them sat Yvonne. Her curly blonde locks swayed lightly in the breeze; she looked at him with twinkling eyes. Like Zac, they were all clothed in wedding attire. Sarah and Mekenna in bridesmaids' gowns, Yvonne in her beautiful white dress.

"Uh, I really wish I could stay and chat but I promised Robert that I'd go straight to the bathroom and be right back to filming," Zac hastily explained.

This drew questioning looks from the trio of actresses.

"Isn't the bathroom inside?" Mekenna spoke up, frowning.

Yvonne raised a brow. "Where are you off to, Zac?"

Zac swallowed thickly. His mouth went dry and felt like sandpaper. The longer her stalled, the worse his physical symptoms became. That, and Yvonne's scrutiny was not helping his withdrawals much either. "I'm going to go…take a walk…rehearse my lines…"

He began backpedaling down the grass slope in the hopes that Yvonne would not notice his suspicious behavior. But luck was not on Zachary Levi's side, and as he turned towards the parking lot, a hand grabbed him by the arm and prevented him from fleeing.

He looked over his shoulder and was confronted by a very stern-looking Yvonne. Zac gave her an exaggerated smile. "Wow, you look spectacular today," he tried placating her. "I mean, you're practically glowing-"

She cut him off. "Where are you really going?"

"Nowhere," he lied. Yvonne's eyes narrowed and he quickly amended, "I was gonna go smoke."

"I thought you said you quit?"

Zac lowered his voice and confessed. "See funny that you asked that, because when I said that I "quit" it was sort of in the heat of passion, and I wasn't considering the fact that I would be in serious amounts of pain for the next month."

Her expression softened. "Is it that bad?" She asked quietly.

"Well it hasn't been exactly rainbows and butterflies if that's what you're asking."

Yvonne bit her lower lip and stared at Zac with compassion in her azure eyes . "I think I know something that will make you feel better," she told him and stole quick furtive glances in either direction before adding, "Come on."

She offered him a hand. Zac, while confused, wasn't going to reject Yvonne. He was just relieved that she wasn't resenting him for almost violating her "no smoking" ultimatum. And so he took her hand and allowed Yvonne to guide him back towards the church.

They entered through a side corridor which led them into a smaller chamber annexed by the church. It was deserted save for the miniature alter built at its end; hangings, religious linens, and other vestments that were scattered throughout the room. Zac crossed over the threshold first with Yvonne now standing behind him. He allowed his eyes to wander around briefly; recognized that they were inside the church's sacristy and felt the corners of his lips pull into a smile.

"Where did you stumble upon this place?" He asked out of genuine curiosity. "You know it's off-limits to the public, right?"

Yvonne pushed the door shut and walked up beside him. "I found it by accident," she explained defensively. "Yesterday, when everyone was still prepping for the funeral scene, I felt like exploring and this room caught my eye. Perfect, isn't it?"

"Perfect, huh?" He repeated. "Perfect for what exactly?"

Her lips curved into a coy smile. "For relaxing," she answered and pointed to a cabinet that had been turned over, adorned with more religious decorations. "Take a seat."

Zac noted the mischievous glint in her eyes and decided to play along. He lifted up onto the cabinet and looked to Yvonne for further instructions. "Now what?" He asked with earnest.

She glided towards him with her white dress billowing behind her. Zac felt his body tense unconsciously. His heart was rattling against his ribcage as she neared. That look she once beheld in her crystal blue eyes had turned from innocent playfulness to just plain sinful. He audibly gulped.

"Now," Yvonne announced in a sultry tone. "I want you to close your eyes, Zac."

He wordlessly followed instructions. Eyes closed, he muttered. "You're beginning to concern me, Yvonne...but what's next?"

He felt her warm breath ghost over his ear and shivered. "Just relax," Yvonne whispered softly. She sank down to her knees and began to undress Zac: first it was the belt, then the buttons and finally the zipper. Once she managed to pull his black pants down to his ankles, she watched Zac as he shifted uncomfortably upon the cabinet's flat surface.

"Zac, I told you to relax," Yvonne said, a hint of annoyance in her tone.

"Are you sure nobody's going to find us?"

She rolled her eyes. "We could have been easily found in the parking garage…so I would not worry about anyone finding us here."

Zac bit his lip and realized that she was right. Since there was no use in arguing with her, he cracked open an eye and glanced downward to where Yvonne was nestled in between his legs. "Touché," he said and nodded, "As you were."

Yvonne interpreted this as her cue to begin. Seeing that he was already getting aroused, she brushed her hand lightly against the growing bulge concealed by his boxer shorts; felt him harden at contact and then continued to stroke him in the same soft manner. Zac clenched his teeth and rewarded her with a strangled hiss. She relished in every noise Zac made and loved to be the only one who could make him lose control.

"God…feels so good," he moaned freely.

She mentally chuckled. Now with the desire to truly feel Zac this time around, she tugged his boxers off his hips and ousted his fully erect cock. She admired it for a moment then traced her fingertips along the base to the tip of the head. His throbbing member twitched in pleasure. Zac whimpered and began to mumble incoherently under his breath.

He's so stressed out, Yvonne realized soulfully. Poor thing, I should've never forced him to quit smoking on the spot like that.

She caressed him once more, then fastened both hands tightly around his rock-hard cock, pumping him slowly. Zac stiffened as she bowed her head and licked up his entire length; flicking the end with the fork of her tongue. She repeated this act several times, each more agonizingly slow than the next. Her gaze focused solely on Zac as she gauged his reactions.

Zac craved for more. He rocked into her when his desire for her touch became overwhelming. Yvonne sensed this and eagerly took him into her mouth. She wrapped her lips around his cock and began sucking, nipping and licking every inch of him. She drove Zac into frenzy. He groaned as she used one hand in tandem of her mouth, her tongue sliding up and down his length while the other hand gently massaged his balls. Eyes squeezed shut, Zac threaded his fingers through Yvonne's hair. He pressed her against him and urged her to devour him whole. She obliged and his thrusts became wild and untamed. Yvonne raked her teeth lightly across his slick flesh and Zac cried out, his lament echoing throughout the empty room.

When Yvonne felt his legs shake uncontrollably—his breaths short and clipped, she knew he was approaching his climax. She increased the momentum by pumping faster, swirling her tongue on the underside of his erection, gently nibbling the sensitive skin. Zac gripped the sides of the cabinet until his knuckles bled white. He peered through his bleary vision and settled upon Yvonne, watching her work in silent awe. She felt his eyes on her. She lifted her gaze to catch him peaking and grinned devilishy; flattened her tongue and trailed it up his aching member. That was the final straw that sent Zac to the brink. He surrendered to Yvonne entirely and breathed her name like a reverence as she swept him into a blissful oblivion.

He sat there uselessly while Yvonne cleaned up the mess. His dick grew limp while she licked him in attempt to ease Zac from his high. He sighed in happy relief; she pulled back, wiped her mouth with the back of her hand and rose to her feet. Zac watched her closely with his chocolate doe eyes. He smiled lazily, but here was a touch of sadness to it.

"Feeling better?" She asked.

He nodded, "Yeah. Thank you." While he did sound grateful, Yvonne sensed that there was still something else that was bothering Zac. He got dressed without meeting her eyes. The room became so unbearably silent that she could hear a pin drop. Yvonne frowned, feeling both hurt and confused.

"You're awfully quiet," she observed. "Will you please tell me what is really wrong with you?"

Zac tucked in his white undershirt and began buttoning up his black jacket, "What are we doing, Yvonne?" He asked exasperatedly, head still down. His gaze flickered to hers, "You have a boyfriend and regardless of who it is, you shouldn't be cheating. Tim doesn't deserve that…and it's not fair, to him or me." Zac ran his fingers through his damp messy curls. "I don't want to keep hiding our relationship from the world, or make sneaking around a permanent habit. All I want is for this to be real…"

"It is real," Yvonne argued. "I promise."

"Then prove it. End it with Tim, or else…" Zac truly appeared to be conflicted. He swallowed and finished, "or else we're done."

"Wait, Zachary—"

Yvonne was interrupted mid-sentence when Zac dug a hand into his pocket and retrieved his phone. It was vibrating with an incoming call. She fell silent when Zac held her gaze before answering, "Hello? It's been thirty minutes already?" His demeanor changed into that of humiliation. "Fuck, hey I'll be there in a few. Tell everyone I am so, so sorry, Josh!" There was a long pause. "Where was I? I was…rehearsing for the scene like Rob told me to," he lied and saw Yvonne trying not to look smug. "Yup, ok. I'll see you." Zac put away his phone and directed his attention back to her. "I have to go, but we'll discuss this later."

He bent forward and gave Yvonne a peck on the lips. She felt her cheeks burn hot; a spectrum of emotions flitted across from her face, ranging from infatuation to mystification. Her heart began to ache the moment Zac abandoned the sacristy. She knew deep inside what she had to do, as much as it frightened her to finally admit it. Her chest tightened and breathing felt like a lost luxury.

So this was what addiction felt like.

Her favorite fix was gone. It was like he had never existed at all. Yvonne pressed a finger to her trembling lips. She had to tell Tim it was over. She had to let him go. Because like Zac said, he did not deserve this kind of betrayal. No one did. Sighing, she retreated out of the restricted room, one burning question still lingering in the forefronts of her mind.

How was she going to break the news to him?

The More You Know: The Sacristy (where the naughty part went down) is where the priest goes after a sermon or whatever to clean up and chill. Its a holy place and off limits to everyone but the priests. So double naughty points for Zac and Yvonne.

An: Told you this wouldn't just be smut! And my, did you see some angst in there? Don't worry, its the good kind. I mean, Zac and Yvonne can't just have a secret affair without some drama and consequences for their bad behavior, right?
