Working Overtime

Summary:

Hinata's first office job doesn't turn out exactly how he imagined, but with a boss like Oikawa? Look. He's not exactly complaining.

Notes:

Hi friends! Welcome to this exquisitely horny Oihina office au (seriously there is no plot whatsoever, it's all porn all the time), brought to you courtesy of Rys, who presented me this au custom designed to drive me crazy and has been patiently supporting me as I've written it bit by tiny bit. Thank you for entrusting me with this fic! :D

I hope everyone enjoys it!

I don't currently have a schedule for updates but I do have 3/4 chapters written. So let's say weekly, probably. For at least three chapters. :3

Chapter Text

1

"Oikawa-kacho," Hinata called as he knocked on Oikawa's office door with one hand, his coffee cup in his other hand. He heard a muffled come in and opened the door, adding, "I'm here about the paperwork you needed to go over with me!"

It was his first day at the office and he was ready to make a good impression. All of his friends had said that Hinata had been lucky to get this job, and he agreed. He had heard nothing but glowing reviews of the company and during his interview, his potential new boss, Oikawa, had been poised and thorough in his questions, leaving Hinata with an excellent assurance that this was the right step in his career. 

The fact that Oikawa was also rather attractive was, you know, a nice bonus.

So when Hinata, wearing his sweater vest and his hair partially tamed with gel, stepped into Oikawa's office, he noticed a few things. First, the office was well decorated and the huge window had an impressive view of the sky and the city. Second, Oikawa might enjoy sweets, because his iced coffee was topped with whipped cream and cute, multicolored sprinkles. 

And third, his new boss was smirking at him with a very self-satisfied expression and another man between his legs noisily sucking him off.

Hinata almost dropped his coffee.

Almost.

(Thankfully for the floor and for Hinata's coffee cup, Hinata had very good reflexes.)

"Oh, I see you're busy right now, Oikawa-kacho," Hinata said, looking at a spot just above Oikawa's head, lest he screw up and try to make out the shape of his dick. "Would you like me to come back in…" Here Hinata faltered, but only for a moment. "...ah, in fifteen minutes or so?"

Hinata hoped that he wasn't insulting the lovely man between Oikawa's legs by insinuating it would take him that long to suck Oikawa off, and he hoped he wasn't insulting his boss by assuming he'd get off too quickly. 

Just, they never covered 'walking in on your boss getting an enthusiastic blowjob' in any of his college classes.

Oikawa twisted his hands through the man's dark, curly hair, and shook his head. Now that Hinata was looking, really looking, he saw the faint pink blush rising on Oikawa's cheeks, the way Oikawa's lips were parted in a soft pant, the way he was staring at Hinata with hunger in his eyes.

"You're welcome to join in," Oikawa said, his voice hitching very slightly over the word join. He raised an eyebrow in invitation.

Hinata didn't squeak, which he was proud of. There didn't seem to be room for him between Oikawa's legs, so, as a warm blush rose to his cheeks, Hinata shook his head. He reached behind to the door, ready to leave. 

"Stay." Oikawa's voice was thick with excitement, his cheeks red. "I'd love for you to stay."

Hinata chanced another glance at the man between Oikawa's legs, who was groaning. He realized Oikawa was rocking his hips up into his mouth faster and harder than before and for a moment, things crystalized.

This wasn't an accidental discovery. 

"Oikawa-kacho…" Hinata started, about to accuse him of orchestrating this whole situation when Oikawa's tangled grip got tighter, and he tilted his head back as he whined softly through what must have been an orgasm, given the wet sounds the man giving him a blowjob made.

"Oh, goodness, Mattsun, that was delightful!" Oikawa murmured, a little breathless, but still quite in control.

Hinata couldn't take his eyes off of Oikawa, even as Matsukawa rose gracefully from between Oikawa's legs. He wiped his mouth with a handkerchief that he folded nearly and put in his pocket before offering his hand to Hinata.

"Nice to meet you," he said, as if he hadn't just had a dick in his mouth and as if he didn't have a rather impressive bulge in his pants.

"A pleasure to meet you too," Hinata said, stumbling over the word pleasure.

Oikawa gestured to Hinata. "Mattsun, give us ten minutes, and then I'll take care of you."

Matsukawa hummed. "With all due respect, I think Hanamaki has a few minutes open about now."

"Go on, then," Oikawa said, dismissing Matsukawa with another gesture. He smiled at Hinata and added, in a stage whisper, "Who am I to get in the way of true love?" He winked, and for some reason, Hinata's face warmed up like he was blushing even harder. "Now, let's go over your paperwork, if you please."

Hinata realized he had his papers in a death grip and breathed out, relaxing his hand. He hoped he hadn't wrinkled them too much as he handed them to Oikawa.

Oikawa made a show of dragging his fingers over Hinata's as he took the papers. Every inch of skin that Oikawa touched tingled in his wake. Hinata was surprised by how electric a simple touch could be. His thoughts wandered back to Matsukawa between Oikawa's legs and then his thoughts wandered to what it would be like to be the one between Oikawa's thighs.

Would Oikawa…ask Hinata to do that for him too? Hinata’s cheeks heated up at the thought, and he did his best not to start blushing. Again.

Yet despite all of, well, everything that Hinata had just seen, Oikawa really did seem to want to go over his paperwork. 

He can’t be in charge if he doesn’t get things done, right? Hinata thought to himself, nodding when Oikawa asked him another question. 

It was just hard to concentrate on work when he thought about the fact that he had seen his boss get a blowjob and yet, he had been so distracted by Matsukawa that he hadn't even seen Oikawa's cock. Oikawa must have a pretty cock, Hinata thought, and then awkwardly shifted in his seat when that thought brought a rush of heat to his own dick.

Oikawa didn't seem to notice; he moved to the next line on the form, confirming the information.

Hinata nodded. He tried, he really tried, to focus on the forms. I can't think about Oikawa-kacho's dick any more!  

So his brain helpfully provided him with thoughts of Oikawa's thighs instead. Oikawa was wearing well-tailored pants that fit across his thighs just tight enough to entice and Hinata had a feeling he'd learned the reason why.

Oikawa moved to the next section of the forms and Hinata moved on to thinking about his boss's chest and how full and thick it probably was under his nice button up shirt. Hinata couldn't help it; now that he was half hard, his body seemed determined to get him all the way there. 

He shifted again in his chair, hoping Oikawa stayed focused on the forms, because in about two minutes, Hinata's hard on was going to be unmistakable. Would Oikawa offer to help him with it like he had offered to help Matsukawa? The thought of Oikawa putting his long fingers on Hinata's dick only served to make him harder.

Damn.

Oikawa tapped one of his fingers gracefully against the paper. "So," he said, apparently completely and thankfully unaware of Hinata's unfortunate erection. "This work is exactly what I was hoping for. This is why I hired you, after all." Suddenly, Oikawa's gaze turned nearly feral as he met Hinata's eyes and grinned, showing his teeth. "I knew you'd be able to deliver."

Blood raced through Hinata's body with one stop in mind: his dick. Hinata could say with confidence that he had never been this hard in someone's office before. He was just thinking about how to blame his red cheeks on the heat when Oikawa turned back to the paperwork. 

Crisis averted? Maybe?

"Ah, thank you," Hinata said, trying to sound confident. Even if his classes hadn't quite prepared him for everything that happened this morning, he knew that being confident and polite should go a long way. 

Oikawa shuffled the paperwork over to the corner of his desk, clearing space and fixing Hinata with another look. "Now, onto the next matter."

Hinata, perhaps somewhat naively, assumed Oikawa was about to give him his next assignment. "Of course. What do you need me to do?"

"Tell me," Oikawa said, never losing his cute little smirk as he pointedly looked at Hinata's lap. "Does thinking about Mattsun sucking my dick turn you on that much?"

Hinata only thought he had been blushing before. Now, embarrassment skittered throughout his body, and he wished there was a way to just turn off his cock, to get it down right now, so that he wouldn't have to be in this awkward situation, who got a hard on in front of their boss on their first day of work, oh my god he was going to be fired and why was that turning him on even more and–

"Breathe, kid," Oikawa said, with a little laugh. "Do I look mad?"

"No," Hinata said. "You don't look mad." He was still so very hard. He tried to think about the weather. It was supposed to rain that weekend. He thought about Oikawa getting rained on, his shirt getting soaked through and clinging to his chest. Damn it!

"Do I look upset?" Oikawa continued, jolting Hinata out of his thoughts. 

"Not at all," Hinata said. Honestly, it was like his dick was trying to break out of his pants at this point and he had to commend its effort. "You don't look upset, either."

"Right." Oikawa crossed his arms under his chest, and Hinata swore Oikawa must have been reading his mind. "I'm not upset."

Hinata breathed slowly. If Oikawa would just dismiss him, he could turn tail and run.

"In fact, I'm really pleased by that," Oikawa continued, smiling. "It means I made a good choice hiring you. Talented and beautiful and open to having fun. Of course, we're here to work hard. But…" Oikawa gave Hinata a look that made him feel completely naked. "I'm also here to play hard."

Was his boss going to ask him to get down on his knees and suck him off now too? Hinata's breath caught in his chest at how much he liked that idea. His already hard dick tried to get harder. He hadn't expected this for his first day of work, but he wasn't complaining in the least. 

"How about you?" Oikawa asked, his eyes lingering on Hinata's pants. "Does your go-getter attitude apply to…everything you do?"

Hinata really needed to breathe. He was dizzy. He was going to pass out. There was no way Oikawa was getting hard again already, right? Well, they had been going over paperwork for a while actually, hadn't they? 

Did Oikawa want Hinata to get between his legs? Hesitating for only a moment, Hinata stood from his chair.

"M-may I?" Hinata asked, daring to glance at Oikawa's lap for any sign of arousal. The dark pants didn't give much away, but Oikawa's gaze sharpened. Hinata took a step closer. He tried to keep confidence in his voice. "Oikawa-kacho? Would you like me to…touch your pretty cock?"

Ohh, that did the trick. Oikawa's gaze darkened and he nodded. "Good boy," Oikawa said, scooting his chair back farther away from his desk to give Hinata space. "Go ahead, show me what you can do." 

Hinata, thinking only briefly about how he was going to scuff the knees of his brand new fancy pants if he wasn't careful, crossed the invisible barrier from the front of Oikawa's desk to the back of his desk, and got to his knees between Oikawa's legs.

"Do you always take directions so well?" Oikawa asked. 

Another thing his classes had never, ever covered: how to give your boss a blowjob that showed your professionalism and eagerness to do the tasks laid out in front of you, but Hinata thought he was up to the challenge.

Hinata had sucked dick a few times before. There had been his grumpy, dark haired kind-of boyfriend during college. A handful of one night stands. He wouldn't say he was the world's best at oral sex, but…he thought back to the scene he had walked in on just a half hour ago. Except for some soft whines and the times he was talking to Hinata, Oikawa had been pretty quiet. Hinata set a goal: he was going to, at the very least, make Oikawa make some noise.

That his first goal at work was to make his boss moan should have been Hinata's first sign that this job was going to be a hell of a gig. But he was a little too preoccupied with the excitement of getting to see Oikawa's dick.

With fingers only slightly trembling, Hinata reached up to Oikawa's waistband. He bit his lip and looked up at Oikawa, who grinned back at him with his soft brown eyes. Beautiful eyes. Hinata had to look somewhere else lest he get lost in those eyes.

He tried looking at Oikawa's chest, but Oikawa honestly looked so handsome in his suit that Hinata's breath got stuck in his lungs again. All this and he still hadn't seen his dick!

Hinata undid the button that Oikawa had redone after Matsukawa had gotten up. He unzipped Oikawa's pants, now aware that, yes, Oikawa was getting hard.

"Oh! I should lock the door," Hinata said, the words out of his mouth before he could catch them. Oikawa hadn't cared about the door being locked earlier, had he? He looked up from Oikawa's lap to his face.

Oikawa's devilish grin let Hinata know what he was about to hear before Oikawa said it: "No need."

"Ah, right," Hinata said, surprised to find himself trembling with excitement. What if someone came in when he had his tongue on Oikawa's dick? The thought was almost too much to imagine.

"Ah, there you go," Oikawa murmured from above him. He threaded his fingers through Hinata's hair. "You like that possibility of being caught, don't you?"

Oh my god, I really, really do, Hinata thought as he nodded. This was not the kind of thing he had expected to learn about himself at work, but here he was with his hand in his boss's pants, tugging down Oikawa's underwear. 

And on his first day, no less! Hinata squirmed, so turned on by the idea of his new coworkers finding him like this and saying things like wow, he was really between Oikawa's legs that easily? that he kept pressing his thighs together like that would help him get off. 

"Do you like what you see?" Oikawa asked in a tone that suggested he knew the answer.

"Oh, yes, Oikawa-kacho, your dick is gorgeous!" Hinata said, unable to help himself; it was, after all, the truth. Oikawa's cock was perfect. Thick and not so long that Hinata would choke himself, it was a pretty shade of dark pink and the visible veins running along the sides just begged to be licked.

Oikawa's dick twitched at the praise and Hinata tucked that information away for later. He pushed down Oikawa's underwear just far enough to get Oikawa's balls out and pressed his lips against them in a little kiss of appreciation. 

"So thorough," Oikawa noted, approvingly. But while the compliment was nice, it wasn't the noisy neediness that Hinata was hoping for, so he focused on the task at hand. Well. At mouth.

Hinata leaned forward, sucking one of Oikawa's balls into his mouth and wrapping his tongue under it. Oikawa shivered a little. 

Ok, I need to do my best. As hot as it sounds, I really shouldn't get caught between my boss's legs on my first day, Hinata thought. His neglected cock ached. He ran his tongue lightly up Oikawa's cock before swallowing around the head, testing out a little bit of pressure. Wrapping his mouth around Oikawa's dick felt really pleasant. Hinata had meant to make Oikawa moan, but suddenly, he was the one about to lose it from the way Oikawa's dick sat heavy on his tongue.

"That feels so good," Oikawa murmured above him, his voice low and warm. 

"Mmmhmm," Hinata hummed in agreement. He took more and more of Oikawa's cock in his mouth, shivering happily when he found his nose buried in Oikawa's pubic hair and Oikawa's dick brushing just at the back of his throat. 

Hinata had never come untouched in his life, at least if he didn't count wet dreams, but he thought this was the closest he'd ever been. What if someone opened the door right now and saw him like this? So desperate for Oikawa's cock! 

Hinata whined deep in his chest, pressing his thighs together again in a useless bid to stimulate himself. He didn't want to take his hands off of Oikawa; Oikawa's soft skin and the curve of his hips left Hinata just as breathless as his cock pressed deep into his mouth.

A moment later, something pressed against Hinata's crotch and Hinata glanced down to see Oikawa had toed off his shoe and was using his foot to give Hinata something to rut against.

Hinata, who even ten minutes ago would have said he wasn't that shameless, shamelessly started rocking his hips against Oikawa's foot; if that's what his boss wanted to give him, Hinata was happy to have it.

In the back of his mind, Hinata remembered his goal: make Oikawa moan, but it was completely overshadowed by the way giving Oikawa a blowjob felt. 

Oikawa's grip in his hair got a little tighter, and Hinata couldn't remember anything except sucking dick, loudly and enthusiastically. The whole office was filled with the wet sounds of Hinata's mouth on Oikawa's dick and the muffled groans Hinata made every time Oikawa rolled his hips to help slide his dick deeper down Hinata's throat.

…And then Oikawa started talking.

"Mmm, you look so good taking my dick like this," he said, tracing his finger on Hinata's lips. 

Hinata tried not to implode. At this point, his blowjob was less technique and more providing a warm, wet hole for Oikawa to fuck into, but Oikawa seemed really pleased with that, so Hinata let him keep going. It was all he could do just to keep rocking against Oikawa's foot, getting ever closer to coming just from that.

"Yeah, take my cock," Oikawa said, his voice deeper and a little breathless. "Are you going to come thinking about how anyone could come through that door right now, just like you did?"

Hinata wanted to nod, but he was helpless to do anything except take Oikawa's cock and honestly, it was all he could think of. He looked up at Oikawa, hoping he could read the agreement in his eyes.

Oikawa grinned. "Oh, sweet Hinata," he said, even more breathless. "You're even better than I had hoped for. Fuck, I'm going to come baby, ok? Just relax and take it, just a few more, just–"

Hinata shivered in pleasure when Oikawa erratically thrust deeper than ever into his mouth, and warm, wet cum slid down his throat. He tried to keep eye contact with Oikawa the whole time, but he had to close his eyes. Sensations overwhelmed him; fingers tangled in his hair, fingers tracing his lips, a foot warm against his crotch, and Oikawa's thick cock in his mouth…helplessly and with a gagged scream, Hinata came in his pants so hard that he had to keep his eyes closed to get through it.

He realized belatedly that Oikawa's slowly softening cock was still in his mouth, though much more shallowly. Hinata was able to relax his cheeks a little and swallow past the slight ache in his jaw.

"You feel so good," Oikawa explained, his voice far away in Hinata's post orgasm haze. "Let me borrow your mouth just a minute or two longer."

Ok, so, Hinata's new boss was two things. One, he was an exhibitionist. Two, he was possibly insatiable. Hinata had a thought at the very back of his mind that maybe he should remind Oikawa that he couldn't do his job if he was kneeling between his legs.

Oikawa carded his fingers through Hinata's hair. "Your mouth is incredible. I hope you don't mind me using you a little more."

Hinata hummed. Having Oikawa's dick still in his mouth was prolonging the nice soft edges of his orgasm, and he liked that. After another hazy minute or three passed, Hinata became more aware that every minute he was on his knees was another minute someone might come into Oikawa's office. 

The whine that escaped Hinata's mouth was involuntary. His cock tried to stir in his pants. Maybe it wasn't just his boss who was insatiable. Hinata was learning a lot about himself today, too.

“Go ahead, rest your head,” Oikawa encouraged, patting Hinata’s cheek. Hinata closed his eyes and did as he was told, tilting his head the last little bit to lay on Oikawa’s thigh. His soft cock stayed easily in Hinata’s mouth and Hinata sighed happily. 

Oikawa started typing away at his laptop. Without his fingers stroking through Hinata’s hair, Hinata’s thoughts started to wander, coming into focus as the high of his orgasm finally faded. Oikawa’s cock in his mouth was still a lovely feeling, but the wet spot in his pants started to clamber for attention, an odd sensation of cool and wet and sticky. Hinata shifted from his spot on the floor.

“Getting a little restless now?” Oikawa asked, and Hinata was embarrassed by how fast he nodded. “I understand.” He waited until Hinata looked up at him and then grinned. “All good things must come to an end. For a little while, anyhow. It's ok, you can get up.”

Getting to his feet was a little harder than he’d anticipated. Hinata did not rise nearly as smoothly to his feet as Matsukawa had.

“Ah, there you go,” Oikawa said. He grabbed his iced coffee and slid it closer to Hinata. “Thirsty?”

Hinata paused, but Oikawa shook his head and didn’t give him a moment to worry about the etiquette of the situation.

“You just sucked my cock,” Oikawa said as easily as if he was merely reading a report. “I think you can share a sip of my coffee.”

“As you say so,” Hinata replied, almost automatically. He took a sip of the coffee, somewhat watered down from the time they’d spent doing whatever the heck had just happened between them. He was surprised that it didn’t taste quite as sweet as it looked, but it was still flavorful and delicious and cold and, most importantly, refreshing.

What was not refreshing was the now awkwardly cold, wet cum inside Hinata's pants. He didn't want to draw attention to it by looking down, but he was also nervous if it was noticeable or not. 

"Don't worry," Oikawa said, as if he could read Hinata's mind. "I don't see a wet spot. Do you need a change of pants?"

"Ah, I–dont have one." Hinats had not brought a change of pants because, and he could not stress this enough, he had not planned on sucking his boss's dick and getting off by rubbing against his foot. 

"I figured. But I don't mind loaning you a pair for the afternoon." Oikawa got up, heading to the shelves over against the wall. He pulled out a drawer and frowned. "I think I have a pair that will fit you well enough."

Hinata ducked his head. "I'm afraid we're quite different heights…"

"So we are," Oikawa agreed, but he presented Hinata with a pair of pants just the same. "I think these will do the trick."

Hinata accepted the pants and wondered how many times Oikawa had done this. Either way, he chose to be polite. "Thank you, Oikawa-kacho, I'll bring them back clean tomorrow."

"There's no rush," Oikawa said. "I think I'll like how those ones look on you. Honestly, I'll probably let you keep them."

Hinata didn't know what to say to that. He was beginning to think that every single business class he took had been useless.
