Boss' Schedule

It had always struck Karin as remarkable how long she had been working for her boss already while barely knowing anything about him. In fact, the only things he did know about him was the information that was publicly available.

Uchiha Sasuke shared the CEO position with his older brother Itachi. He hailed from one of the oldest families in town and was easily one of the most handsome men in existence; the type of beauty described in every poem and every song. He spoke three languages fluently and had started working at his family's company four years ago, quickly raising in rank thanks to his skills. And that was all that was known about him.

They always said that a personal assistant was one of the closest people to the boss, but frankly Karin didn't know that much more about Sasuke than outsiders did. He was a hard worker, yes, but that could be gleaned simply from how quickly he had risen in rank since he had started to work. He was polite, but standoffish, and nobody outside his family seemed to ever get close to him. His schedule was always filled from morning to evening, even during weekends – and that was the part that was most puzzling of all.

Because Sasuke was an Alpha and even if one didn't know that much about Alpha, one thing everyone was aware of: an Alpha's rut.

Alpha's ruts tended to occur every two to three months, though they could be monthly when triggered by an Omega's heat. For three to four days, an Alpha would be, well, not really incapacitated, but their minds definitely would not be set on the daily grind of doing their jobs. They would either lock themselves up in their room and entertain themselves so to speak, or they would share their rut with their partner or escort. Either way, they would always take some days off, unable to focus on the daily tasks.

Karin had been working for Sasuke for four years and in all those years he had never taken so much as one day off. As a healthy Alpha, he definitely should be having a rut at least every two months, but he always showed up every day on time without fail, never looking the least bit bothered. How was that even possible?

The only explanation Karin could come up with was that he purposefully subdued his ruts by taking specialised medicine like Omega took suppressants for their heats. She wasn't quite sure how healthy that could be in the long run if Sasuke never let himself have a rut, but she could hardly start discussing her boss' rut with him! At best she would be kicked out of the office before she could even finish her first sentence, at worst she could be fired.

So no, even though she had her own opinion at how her boss might be handling his ruts, she was going to keep her mouth shut. Because unlike certain people, she actually knew when to keep quiet and when to speak.

Sasuke could be described with many adjectives. Handsome, smart, eloquent when needed, controlled, even charming when absolutely necessary. The thing with Sasuke, however, was that most of the time he was standoffish to the point of almost being rude. He could actually be quite rude if people encountered him on a really bad day.

After four years Karin had become used to greeting a rather surly Sasuke in the morning. She never took it personal when he would either ignore her greeting or grunt something in return; she had once overheard his brother teasing him that he wasn't a morning person at all and yes, that did fit him quite well.

Which made it all the more noticeable when on a dreary Monday in February Sasuke actually left the elevator in a good mood. He wasn't outright smiling, but his eyes were lighter and he didn't look like he was about to throw his briefcase at the first person who looked at him wrongly.

"Good morning," Karin told him, a bit taken aback by his light mood.

She was even more bemused when he dipped his head in return and gave her an equal light, "Good morning." back.

Huh, that was … unprecedented.

She watched him walk into his office, closing the door behind him like usual. Not even a minute later, the door opened once more and he popped his head through.

"Itachi will show up soon for a meeting. You can tell him to just enter my office when he arrives," he told her.

Now she definitely knew something was up. In spite of being brothers, Sasuke had never given Itachi free reign to enter his office, citing that the "bastard will only take that as blanket permission to keep bothering me afterwards". But now he could just walk into the office? Just like that?

"All right, I will tell him," she agreed and he gave her another nod before closing the door again.

She sat there, staring unseeingly at her screen, contemplating what had just happened. Sasuke was actually … in a good mood? During the early morning at work?

A shadow falling across her desk had her looking up, straight into Suigetsu's eyes. He dug his hip against the edge of her desk, crossing his arms. His tie was already loosened, even though it was barely eight thirty.

"You think someone drugged his coffee?" he asked out of the blue, nodding at Sasuke's office.

She raised an eyebrow. "You noticed it too, huh?"

"He nodded at me in greeting and didn't even tell me to fuck off when I made a joke," he said incredulously. "When the fuck has it ever happened that he took that giant stick out of his arse?"

"Well, certainly never around you," she quipped. "In fact, I don't get how you're still employed after all the shit you've spouted so far."

He grinned, flashing his sharp teeth. "I'm a charmer, of course!" He sobered up quickly. "No seriously, what the hell is going on with him? He's in a good mood. When the fuck has he ever been in a good mood here? I didn't even think he was capable of experiencing that!"

She glanced at the closed door again, nibbling on her lower lip. "I have no idea," she murmured.

It was an interesting development for sure. Perhaps it was just a one off thing, though?

It wasn't a one off thing.

Every morning after that particular Monday Sasuke would walk into the office in a good mood. During some days there was even the faintest hint of a smile gracing his handsome face!

Naturally such a development couldn't be left undiscussed, so the rumour mill was working overtime, trying to figure out what could have their infamously surly boss suddenly in such a good mood.

"He's going to fire everyone here and is rejoicing in that fact!" one employee claimed with a quiet wail.

"Bullshit, first of all, the company can't do shit with just two people and two, you think his brother would go along with that?" was the instant retort.

One hypothesis down.

"Maybe his brother is stepping down, leaving him the sole CEO position?" another one suggested hesitatingly.

The idea was considered, but thrown away after a while when there were no signs of Itachi stepping down or leaving the company.

Second hypothesis thrown to the gutters.

"Their grandfather died and left him the majority of the inheritance?" was another rather farfetched theory.

Farfetched or not, research was done and they discovered that Uchiha Madara was still in perfect health – so were Uchiha Fugaku and Uchiha Mikoto, Sasuke's and Itachi's parents, so the inheritance theory was fully debunked.

The third hypothesis shrivelled away like a paper in a flame.

The fourth hypothesis, "He was secretly replaced by a pod person!", "Idiot, you really think anyone could replicate his cold beauty?!", was discarded before it could even enjoy one minute of existence.

Theory after theory was wildly thrown around, one more outrageous than the other one, until suddenly someone, a young nervous woman, suggested awkwardly, "Maybe he's fallen in love?"

That theory left them all stumped for a good minute, before everyone broke down in near hysterical laughter to the point some sank to the floor and others started crying from the force of their amusement. Uchiha Sasuke in love? That had to be the most ridiculous theory ever and someone had actually come up with a pod person theory! There was no way their boss' good mood was the result of a relationship!

"Why not?" the young woman asked naively confused. It was adorable, really, how bemused she sounded. Clearly she hadn't been working here for very long yet.

"Because the boss doesn't do relationships," Suigetsu answered, thoroughly amused. "I lost count how many times he's rejected people over the years. Goddamn, but that was always hilarious as fuck!"

"Sadistic douchebag," Ino shot back flatly.

"Aw, sweet cheeks, at least you got the hint after the first time," he grinned. "Your friend on the other hand …" He snickered.

"He can't be that bad," the young woman tried, but seeing everyone's face had her stumped.

"Oh no, he is that bad," Karin confirmed. "It's honestly awkward every time. If they're lucky, they get a polite rejection, but if they're not …" She whistled lowly.

Another thing Sasuke excelled at after all was having a sharp tongue. He also very clearly did not discriminate: man or woman, if you tried to push him enough, he would give you the tongue lashing of the century. It would be impressive, if it wasn't so horrifying to watch.

Sasuke having been replaced by a pod person was more likely than him actually being in a relationship!

The rumour mill was still doing some major overtime when a notification appeared on Karin's laptop, informing her that she needed to block off Wednesday to Saturday in Sasuke's schedule.

Thinking it was a joke at first, she checked the sender twice, but no, the notification really had been sent by Sasuke.

Mystified, she stood up and knocked on the door, the sound just loud enough to be heard over the continuous whirring sound of laptops and a printer swiftly spitting out paper after paper as people discussed cases with their colleagues.

"Come in," Sasuke called out.

He glanced up briefly from his laptop when Karin poked her head through the gap between the door and the doorframe. "Karin, something you need?"

"I just received your memo," she smiled. "I was just curious: any reason for the days off? Are you going on a holiday?"

She couldn't remember him ever having gone on a holiday that wasn't a mandated time off from the company itself. Perhaps Itachi's pestering had finally brought him to his breaking point? She had overheard the two brothers arguing before over how Sasuke really should take more time off to relax.

"No, not a holiday," he said absently as he typed away. "It's for my upcoming rut."

"Oh, of course. I'll block off those days in your schedule then," she said pleasantly and returned to her desk.

It was only when she sat down and called up Sasuke's schedule that his words finally registered in her brain.

Sasuke was going into a rut?! Since when?!

It had been years since he had last gone into a rut, but he already loathed the way his suit stuck to his body as he fought with his key to get the damn door open. He seemed to be burning up from within and he would almost suspect he had caught the flu, if it wasn't for the raging desire to fuck his Omega that had distracted him all the way from the office's garage to his front door.

Before he could actually break that stupid fucking key in frustration – why the fuck wouldn't it just go into the lock from the first try?! – the door suddenly opened, bringing with it the heavenly scent of an Omega.

His Omega.

"I'd say you look like crap, but honestly even now you look good," Naruto sighed, as if he was lamenting that fact. "I look like shit during my heat, but of course you look amazing during your rut. Life's unfair, man."

"You're here," was all Sasuke could think of to say as he hungrily took in how Naruto looked.

He wore a light blue button up shirt, which was definitely not his and most definitely Sasuke's, because Naruto didn't own any button up shirts. The first two buttons had been left undone, offering a tantalising glimpse of the tanned, smooth skin underneath, the dip of his collarbone visible whenever he moved slightly. He wasn't wearing any trousers, save for a boxer short, of which the edges peeked from underneath the shirt. The sight of his bare slender legs had Sasuke hastily pushing him backwards, slamming the door shut behind him. Like hell was he going to let anyone look at what was his.

Naruto allowed the manhandling easily, letting himself be pushed up against the wall while Sasuke's briefcase ended up somewhere … near the door perhaps, but he didn't care about that now. What he did care about was Naruto spreading his legs for him, letting him fill in that space while the blond man looped his hands around Sasuke's neck. The Alpha's own hands found purchase on Naruto's hips, grabbing them firmly, rucking up the shirt slightly. He lowered his head to Naruto's neck, breathing in his enticing scent.

Naruto's unique scent had been alluring from the very first moment he had accidentally walked straight into Sasuke at the local coffeeshop, but his scent was driving him absolutely mad this time. If pressed to compare, he'd say it was just as intense as during Naruto's own heat, though this time it made him feel drunk instead of just intoxicated. It made him press up against Naruto even harder, sliding his nose back and forth across that patch in his neck where the scent was the strongest.

"Deidara-kun texted me," Naruto murmured and only his fingers running through Sasuke's hair and one of his legs lifting up and curling around Sasuke's hip stopped the Alpha from snarling at hearing another man's name leave his mate's mouth.

Fuck the fact that Deidara was an Omega as well and tied to his brother – Naruto was his.

"Said that I should get to your home because your rut was about to start soon," Naruto went on, letting out a small gasp and tugging at Sasuke's hair when Sasuke kissed his neck, pressing his teeth against the skin but not biting down. Yet. "So lucky you, I can take a break off work and spend your rut with you."

"You changed clothes," Sasuke commented, his mind fixated on how little and yet still so much Naruto was wearing.

He wanted everything gone, he wanted his Omega naked, bared for his eyes only, while he ran his hands all over that smooth, pretty skin, touching him all over until Naruto was so wet, he would start leaking slick all over himself …

Naruto sounded slightly breathless when he replied, "Hm, thought it'd make for a nice surprise. What do you think?"

Sasuke's answer was to capture that alluring mouth in a deep kiss, taking immediate control over it while he shoved up the shirt, finally giving him access to Naruto's stomach. He slipped his hands over Naruto's sides, up, up, until he reached his chest and thumbed his nipples, which pebbled almost instantly underneath his touch. Kicking Naruto's legs further apart, he pushed his entire body flush against the wall, letting him feel how hard he was. Naruto, to his delight, was already in the same state as well; his scent becoming even stronger as he became aroused.

Naruto pulled away with a sharp gasp, gulping for air. He twisted his head to the right, baring his neck to Sasuke who took the invitation to start marking him up for the first time of what would become many, many times over the next four days.

"Bedroom, now!" Naruto urged, even going as far as kicking Sasuke's arse with his foot when the Alpha didn't react immediately.

The dig in his arse and the command had him snarling, shoving Naruto's body up the wall until he could brace his arms underneath that arse. He took his time digging in his fingers in that supple, thick flesh, humming darkly when the boxer short started to feel damp. He pressed his thumb against Naruto's entrance, the fabric of the shorts the only thin barrier separating them. The pressure, slight and teasing as it was, had Naruto whimpering, rocking into Sasuke's stomach.

Abruptly deciding that he still had enough time for teasing later on, Sasuke stepped away from the wall, pulling Naruto with him. The Omega yelped in surprise, tightening both legs around Sasuke's waist and locking his arms around his shoulders.

"Give a guy a warning, will you?" he scolded, but hissed when Sasuke nipped at his lower lip.

"You're the one wanting to go to the bedroom," Sasuke reminded him snarky and marched towards the room in question, too impatient to keep stalling any further.

"Yeah, because my back hurt like hell after the last time you fucked me against the wall," Naruto complained, but his hips didn't cease rolling.

Sasuke's sinister smile had Naruto's legs tightening even further around him. "Who was the one who kept provoking me then, hm?" he reminded his mate darkly. "You weren't complaining back then when I fucked you stupid."

A dark part inside of him still felt smug when he remembered Naruto had been limping the day after that particular round.

Naruto blushed fiercely. "That was …." he fumbled, but couldn't come up with an excuse that would let him keep his dignity.

Sasuke wasn't particularly interested in hearing an excuse anyway. As soon as he crossed the threshold to his room, he was in front of the bed in just a couple of steps, dropping Naruto on it. He yanked off Naruto's shirt, a button springing away to freedom, and threw it down onto the floor, swiftly followed by the boxer short.

Before Naruto could protest the rough treatment, Sasuke pushed him down and climbed on top of him, kissing him again and again, sweeping his tongue across Naruto's mouth. As soon as those plush lips parted, his tongue curled around Naruto's, tasting him. Occupied as he was by their kisses, and loathe to let go for even one second, the removal of his own clothes was a bit hampered until Naruto helped him get rid of everything, finally allowing their naked bodies to slide against each other.

Any other moment and Sasuke would take his sweet time teasing Naruto, preparing him for so long that it would end with teary blue eyes and a cracked voice begging him to just "fuck me already, bastard, please!". He would take Naruto apart until the blond man was nothing but a trembling, moaning wreck who could barely gasp his name when he came.

But any other moment didn't have him experiencing his first rut in years, though. His brain was utterly muddled by now, only knowing Naruto. His skin, his touch, his kisses, his fingers grasping at Sasuke's shoulders, nails digging into Sasuke's back when he abruptly plunged two fingers inside that soaking wet entrance. Naruto's quiet whimpers and choked moans when Sasuke's fingers slid deeper, deeper until they reached that one particular place inside the pretty Omega, one that had his back arching and his sweet voice pleading for more. That had even more slick dripping out of him, making him blush when a third finger made the lewd wet sounds undeniable.

Naruto pulled him down, kissing him urgently, messily, almost desperately and Sasuke kissed him back; the fire in his veins having him clamp down a hand around Naruto's wrists, bringing his arms above him and against the pillow, pressing down hard so that he couldn't leave. He couldn't go, couldn't leave, he had to stay, here with Sasuke.

Naruto, Naruto, Naruto.

His whole being sang his mate's name and he swallowed Naruto's keen when he released his wrists, only to grab both his legs and bring them up, bending them at the knees. This way his mate's body was bared for him completely and he growled warningly when he felt those slender legs trying to close. His entrance glistened, reddish and so welcoming, and Sasuke snapped.

Keeping Naruto folded in half, a part of him marvelling at his mate's flexibility, he lined himself up with Naruto's entrance, plunging inside in one thrust. Naruto shouted, throwing his head back, as his body swallowed Sasuke completely, his muscles contracting and moulding around Sasuke perfectly, like he was made for him. It tried to suck him back in when he pulled back and eagerly tightened around him when he thrusted back inside, filling his mate completely. The generous slick Naruto's body was eagerly producing and the preparation beforehand made fucking his mate easy; the sounds of skin slapping and Naruto's ragged moans driving him crazy.

Kept in this position, on his back with his legs bent and pressed against his chest, his cheeks and neck flushed, and his blue eyes clouded over with lust, Naruto was a sight to behold. And he was all Sasuke's. Only Sasuke's, nobody else's.

Nobody else would know how Naruto would keen and whimper every time Sasuke struck his sweet spot dead on. Nobody else would know how pretty his blue eyes looked when he started tearing up, the overload of pleasure becoming too much. Nobody else would get to hear his sweet moans and wretched groans when Sasuke started fucking him harder, pressing in as deeply as he could, forcing his Omega to accept everything he gave him.

And oh, did he accept Sasuke. His muscles rippled and tightened every time he drew back, desperate to keep him inside; his body trembling with every thrust that made the bed rock and thump against the wall.

"SASUKE!" Even in this position, Naruto's back still arched slightly when he came, spurting all over his stomach and Sasuke's, his eyes scrunched shut and his nails digging into Sasuke's back, scratching even when Sasuke pushed fully against his sweet spot, prolonging his pleasure.

When shiny wet blue eyes opened and locked onto his, Sasuke could no longer hold back. He came hard, filling Naruto to the point that some of it started to drip out already, mixing in with the slick already staining the covers that they hadn't bothered to draw back before Sasuke had started to fuck him.

He had enough presence of mind to help lower and straighten out Naruto's legs, before he collapsed on top of him, still remaining inside his mate. The fire in his veins had weakened for now, allowing him to catch his breath while Naruto's hands caressed his back, smoothing the stinging grooves he had created with his nails.

"Well, you clearly didn't lie about having stopped with that medicine," Naruto said drowsily; the occasional tremor still wrecking his body every once in a while, making his legs twitch on either side of Sasuke.

Sasuke snorted and turned his head so that he could look at Naruto. "You already regretting this?"

"Why the hell would I regret getting fucked?" Naruto said incredulously. He smiled mischievously when he added, "You know I love your dick."

His eyes widened almost comically when Sasuke sat up, growing hard again. He grabbed Naruto's hips and dragged him towards him, so that he ended up straddling Sasuke's lap, his upper body still reclined against the mattrass.

"In that case," Sasuke murmured, watching Naruto's eyes darken in response, smelling the way his body was already reacting again, "who am I to deny you of what you love?"

The whole company was actually petrified when their boss walked into the building the Monday after his unexpected holiday, whistling.

Whistling!

Clearly this was a sign that the world was about to end, no doubt about it! Their boss in a good mood? Fine, they had got used to that, but him actually whistling? If the heavens were to crash down right now, crushing all of them, they wouldn't be surprised!

Only Karin was aware of the true reason why their boss was in such a chipper mood – and if she hadn't been, well, the bruise like marks near his collar really were quite conspicuous if you actually dared to look.

She didn't really dare to look. Nor breathe in when he walked past her; the scent of a satisfied Omega still clinging to him.

Guess she knew a bit more about her boss now: clearly he was good at everything.

The End

AN2: I have at least one more fic planned revolving around an Alpha's rut, but honestly, don't be surprised if my brain comes up with more. My muse has been putting in a lot of overtime these past couple of years, obviously. This was a change from the usual Omega heat fics, so I hope it wasn't too bad!

Please leave your thoughts behind in a review; should you spot any mistakes, please point them out to me.

I hope to see you all back in my future stories! Please stay safe and take care of yourselves!
