A/n: the last chapter was short and rushed. I apologize.

You guys are filthy creatures. I love you guys. *creates heart shape w/ hands*

"Good morning."

"G – Good morning," Answered Yamaguchi while bowing his head. His boss walked past him without sparing a single glance and shut the door to his office. The brunette let out a sigh he didn't know he was holding and sagged against the wall.

Ever since the …Blowjob Thing, his boss – Tsukishima – had rarely asked for his presence, let alone touches him. Yamaguchi, being a perfectly normal male that he is, would undeniably grow frustrated eventually. Tsukishima was the one seducing him – but now he's leaving him unfulfilled? What nerve!

But of course, Tsukishima is his boss, after all. Not like he could do anything about it.

Except, touching himself regularly.

While thinking about his boss scolding him.

Now that's – that's not normal, he knew.

"Fuck…" He groaned. "What have I gotten myself into…?" He settled into his compartment and slid down on his chair. Just as he was about to check the paperwork piling on his table, one of his co-workers peeked from behind the partition.

"Morning, Yamaguchi." He greeted.

"Um… Good morning." Yamaguchi replied doubtingly. He never actually talked to anyone but Yachi, so it strikes him as weird when someone just leisurely starts off a conversation like that.

"So I heard from Yachi-san," His colleague started. "That you're finally a permanent staff here! Congratulations!"

"Oh… thanks, I guess." Yamaguchi bashfully grinned.

"You just graduated right? Man, that's fast," The guy said, nodding his head in acknowledgement. "The other staffs said that Tsukishima-san likes you a lot. Is it true?"

"W – What?" Caught off-guard, Yamaguchi stiffened in his seat. "N – No, that's not… uh…"

"Hey, c'mon, it's awesome, really. Tsukishima-san is popular but he's also really cold and strict, you know. It's amazing if you're able to get into his good side!"

Yamaguchi's smile wavered. Yeah, sure. Good side.

"Anyway! The reason why I came here is because I – well, and the other guys too – wanted to throw you a welcoming party!" his workmate declared excitedly.

"Welcoming… party?" Yamaguchi eyed him incredulously. He was never a social kind of person, and he never knew the benefit of throwing a party.

"Yeah! Everyone would be there! Even Kiyoko-san from the financing department!"

"But… I don't even know her." He barely even knew everyone in his department, moreover from outside of his department.

"Then you're missing on a lot." At the sound of door opening, the guy hurriedly turned around and lowered his voice. "Anyhow, it's tonight, and I'll talk to you later alright," He said before disappearing to his own office space.

Yamaguchi was left staring distantly at the wall, thoroughly puzzled. Not only that he had been invited to his own Welcoming Party without his consent, the party was exactly that night also. And he wasn't even able to decline.

He did say everyone would be there, didn't he?

Then, would Tsukishima be there too? Fat chance, though, he didn't seem like the type to attend any occasion such as that. He'd only see it as a nuisance…

The thought of Tsukishima glowering in the middle of obnoxiously drunk people made Yamaguchi smile a little.

It wouldn't be so bad if Tsukishima were to come, though, since he's the boss at his current department.

But then, who was he kidding? Of course Tsukishima wouldn't have time for this cheap bullshit.

"For our cutest junior, Yamaguchi Tadashi – Cheers!"

Yamaguchi only knew a few people from his office, but the others? Not really. More than a welcoming party – it looked like these people just needed an excuse to meet up and get drunk together.

"Yamaguchi!" He heard a familiar sweet voice calling him, and he turned around almost immediately. Yachi was sitting at the other table, waving at him. Next to her was a woman who looked older than he is, a dignified air loitering around her.

Yamaguchi crawled closer to her and away from the commotion.

"Yamaguchi, this is Kiyoko-san. She's the company's management accountant and – "

"…Yachi's friend." Kiyoko continued softly, followed by a quiet squeal coming from the blonde next to her.

"Y - Yeah…" Yachi nodded. "And um, this is Yamaguchi. He was an intern for a few months back, but Tsukishima-san decided to hire him permanently with no apparent reason. A – And he's really kind and reliable!"

Yamaguchi blushed slightly at the compliment. He bowed his head at Kiyoko, who did the same in return. "Nice to meet you. Thank you for taking a good care of Yachi."

"Ah, n – no, Yachi-san was the one who helped me a lot!" He responded bashfully, shaking his head.

Kiyoko chuckled before eyeing him up and down. "So, you're the talk of the sales department, huh?"

"Wha… What do you mean?"

"Ah," Yachi chipped in. "Tsukishima-san is the sales team manager, but he is known to be very intolerant and unfriendly – even though his job involves schmoozing and sweet-talking other people. In any case, he rarely shows any interest in his subordinates or even his bosses, but he's been keeping tabs on you, hasn't he, Yamaguchi?"

"Well..." Yamaguchi picked his nails nervously. "I thought it was… pretty normal?" Oh hell, like anything with that guy is close to normal.

Kiyoko laughed softly and shook her head. "It's really not." She supplied. "That's why it came as a surprise to everyone."

The thought of being Tsukishima's special subordinate made his blood rushed to his cheeks. He was a little grateful his boss didn't come tonight; because he was afraid he'd make a fool of himself eventually.

"Anyway! Let's have a toss for Yamaguchi!" Yachi exclaimed happily, holding a huge glass of beer. For someone so cute and tiny, she sure could hold her drink well. "I know the other guys had already done that but you looked so uncomfortable back then, I felt sorry for you,"

Yamaguchi gasped. "W – Was it that obvious?"

"Not really, but if I were to be in your position, I'd definitely be like that too," She grinned nervously.

"Don't worry, Yamaguchi. They're good guys once you know them well," Kiyoko said, grabbing her own glass. "So, shall we have a toss?"

Yamaguchi paused to gaze at her, mesmerized by her beauty, before finally nodding along. "Alright,"

Yamaguchi lost count of how much beer he drank. He wasn't the type to get drunk easily, though, so even when Yachi was sleeping soundly on Kiyoko's laps, he was still sober – just a little tipsy.

There were a lot of people coming to his welcoming party, and he had the chance to actually talk to some of them. Like the obnoxiously loud Tanaka and Ennoshita from the HR section, the oblivious Lev Haiba – from the Russian sales team, the endearing Misaki Hana who supervises the IT section and many more. There were all very kind and friendly, just like Kiyoko said, and Yamaguchi could feel the tension gradually seeped out of him.

"So you're the guy that Tsukishima talked about, eh?"

"Oh, he talked about me?"

Ennoshita nodded. "I was the one who's supposed to be in charge of the new employees, but I can't believe that Tsukishima actually went straight to me to discuss about you."

"H – He… He did?"

"I was shocked as well. He rarely greets me, let alone actually talks to me. Oh, but this is supposed to be confidential – don't tell him I say this, alright?" Ennoshita smiled.

Yamaguchi could only nod briskly, his whole face felt warm.

"He's close to one of the board chairmen though – the one named Kuroo. Have you met him yet?"

"Kuroo…?" Yamaguchi swept his gaze to the crowd surrounding him. "You mean the…" He moved his hands wildly on top of his head.

"Yeah, the one with the ridiculous hair," Ennoshita snorted. "You'll be seeing him a lot in your office, since he's what Tsukishima calls… friend. I guess," He shrugged, unsure of his own words.

"I see," So apparently, Tsukishima was still capable of making friends. Yamaguchi learnt something new today about him. "But isn't he… a little too young to be with the board?"

Ennoshita looked away to watch a shirtless Tanaka dancing wildly on top of a table with an amused smile. "Everything's possible when you're the president's son,"

"Oh," Yamaguchi blinked.

The older man fished out his lighter and a box of cigarette from his pants. "I'll be out smoking, want to join?"

Yamaguchi politely shook his head. "No, thank you. I think I'm going to go back…" He looked over at his wristwatch hurriedly. It was an hour and half before midnight, and he was afraid he'd miss the last train.

"What's the rush?" Ennoshita stood up, chuckling softly. "It's your party, after all," He said before walking to the direction of the door.

Yamaguchi forced himself to smile, watching the commotion before him unfold. His party? What the heck? Then why was he sitting by himself by the corner? Was it because he wasn't able to get drunk, like the others?

He sighed tiredly, grabbing his tie from the ground. Just as he was about to stand up, someone tapped him lightly by the shoulder. He turned around to face Kiyoko – whose face was only inches away from his. He tipped backward reflexively, embarrassed.

"Ki – Kiyoko-san? Wha, What's wrong?" He stuttered, holding his weight with his hand.

Kiyoko smiled apologetically, pressing her index finger to her lips. Yamaguchi brought his gaze to the sleeping girl on Kiyoko's grip, her face flushed red. Yamaguchi opened his mouth but didn't say anything, only nod in understanding. Kiyoko patted his back and whispered a hushed thanks before carrying Yachi on her back and paced to the exit. For someone as elegant as her, she's pretty strong, he thought.

After Kiyoko left with Yachi, he spent the next fifteen minutes forcing himself to laugh at his co-worker's bad jokes and sitting around sipping his unfinished glass of beer before deciding to leave for the day. He stood up wobbly and bid farewell to his friends. Once he stepped outside, he inhaled deeply and stretched out his hands. It felt nice to finally be outdoor, free from the smell of smoke and alcohol in the air. It was already late, though, and as Yamaguchi was about to walk to the taxi stop, a shiny, black sport car drove behind him and the low hum of its engine caught Yamaguchi's attention. He looked over his shoulder at the car, when a hand popped out from the driver's window, gesturing him to come closer. He must be pretty drunk by then because he innocently obliged.

At this point, he must be really drunk, because he saw Tsukishima on the driver's seat, peering at him.

He violently rubbed his face.

Tsukishima was still there.

"I'm drunk," He stated, not sure to whom.

Tsukishima pursed his lips in distaste. "I sure hope you're not."

Yamaguchi gasped, loudly, and jumped backward. He was perfectly sober, and his boss was indeed right in front of him, inside his luxurious sport car. "Tsu – Tsuki – Tsukishima-san?!" He stammered, piercing through the quiet of the night. "What… What are you doing here?!"

"I was invited," Tsukishima replied flatly. "In act of politeness."

"O – Oh… Right." Yamaguchi blinked away his fuzziness. "Of course you are… but um, I didn't see you…"

"I rather not." Was the guy's answer. "Were you enjoying yourself?" Tsukishima asked in return, tone heavy with sarcasm.

Yamaguchi looked down at his feet, unable to come out with a decent answer.

"Thought as much." Tsukishima said after a deafening silence. Yamaguchi raised his eyes tentatively to look at him when he heard the sound of car doors unlocking. "I've been waiting for you. Get in. We need to talk."

The inside of the car was crisp and cold, and smelled like a mix of cheap air freshener and smoke. He was pretty convinced his boss only wanted to talk, but as soon as he was seated inside, Tsukishima gripped his shoulders roughly and shoved his tongue down his throat.

Damn. So much for talking.

Tsukishima's lips were cold and chapped against his, and he wondered just for how long he had waited for him in this cold. He swallowed back his moan when he felt the blonde bit his lower lip, prying it open. He did as asked and exhaled a shaky breath. He felt so weak now, and it not even a minute had passed. He raised his hand, trying to touch Tsukishima, but the guy caught his wrist and pushed his hand away just as he suddenly broke the kiss.

Yamaguchi gawked at the hot mess in front of him, his mouth hanging open and breath short. He could feel the sharp nails, slowly digging into his wrist and he hated himself because he was enjoying every second of it.

"Well, aren't you desperate," Tsukishima said coarsely, lips splitting into a feral grin. "You're just like a dog who haven't been fed for weeks,"

Yamaguchi's heart threatened to jump out and ripped his chest open, just as his breathing got heavier. He must be burning red right now, because he couldn't feel his face at all.

Tsukishima angled his head to the side; the dark expression on his face stayed exactly the same. "I don't really hate dogs, you know."

What's that supposed to mean? What's that gotta do with anything?! Maaannnn, Fuck it.

"…Am I a good dog?" Yamaguchi asked quietly. Tsukishima laughed sourly and tipped the brunette's chin with his cold fingers.

"I'm only going to ask you once, and I am not forcing you on anything," Tsukishima started gravely, glaring down at Yamaguchi. "So clear your head before answering."

Yamaguchi squinted his eyes in confusion before blinking rapidly, shaking the fog off of his mind. "I'm sober," He told Tsukishima meekly.

Tsukishima stared at him sharply before finally, opening his mouth. "I won't repeat this – are you sure you want to go through all this? You know what I'm like, what I'm into. And please note that I won't tolerate any half-assed answer or second thoughts."

Yamaguchi's eyes widened in surprise and he was left speechless by the question. He didn't expect Tsukishima would actually ask for his permission, after all of that hell. So, what happened back then was just the beginning? Could there be more of this sinful desires he plunged himself into? Just the thought of it made him shiver. He scrunched up his face before answering; his mouth seemed to move on its own.

"Yes," He breathed out; almost desperately. "Do it. I want you to humiliate me. Inflict more pain on me." It was addicting; the shame, the pain, the thirst. It felt like opening a door to a dangerous world he didn't know before.

Something flashed inside of Tsukishima's dark, hazel eyes.

"… Please," Yamaguchi ended with a content sigh, and without any further ado, Tsukishima started his car and stepped on the gas.

"There won't be any written contract because it's too much work," Tsukishima said quickly while loosening up his tie. "But I need you to follow my rules, or there will be consequences."

Consequences didn't sound so bad for Yamaguchi.

Tsukishima drove Yamaguchi straight to his house, and after what it feels like hours of ferocious making out, they finally got into Tsukishima's rather spacious bedroom. Yamaguchi hadn't got the chance to look around though – as he was immediately shoved to the bed and with Tsukishima on top of him, it was enough to shut him up.

"First, you are not to engage in any sexual activities with anyone else other than me without my permission. Other than that, you can freely date anyone." He traced Yamaguchi's freckles with his thumb slowly, gazing down at him. "Understood?"

Yamaguchi nodded. "I don't sleep around,"

"Next – We are not allowed get romantically involved with each other. If you were to harbor any feeling towards me, I shall end everything."

Yamaguchi swallowed. Now that's a hard one. "I understand." He said softly.

"I'm pretty sure you already knew what the safeword is for, then lastly… Keep it professional." Tsukishima added.

Yamaguchi was still contemplating his choice for the second one, he was so desperate, and it hurt. He couldn't handle the anticipation building inside his stomach – or was it lust? Either way he didn't care, not when he could feel Tsukishima's groin pressing against his.

"Yes, yes," He said impatiently, trying to move his hips. "I understand, I won't do anything I'm not allowed to, so, please," He urged, biting his lips.

Tsukishima tilted his head and laughed mockingly. It was dark and bitter, but enough to leave Yamaguchi's mouth dry. "You don't get to make demand," He said pitifully, dragging his nails to Yamaguchi's skin, just right above his hipbones.

"I don't get to make demands," Yamaguchi echoed obediently.

Tsukishima licked into his mouth and he liked it. He liked how Tsukishima tasted like, he liked Tsukishima completely – his look, his obsession, his whole existence. But he couldn't say it, not now or ever, because it'd ruin everything. His feelings would shatter all of his fantasies and desires, so he buried it down, deep inside his heart.

"Yamaguchi," Tsukishima grunted, grinding their hips together. The latter moaned, licking his swollen lips while desperately trying to keep his rationality.

But then it stopped.

Tsukishima climbed out of the bed suddenly, leaving nothing but cold air at his wake. Yamaguchi cracked an eye open and watched as Tsukishima rummaged through his dresser and drawer frantically.

He came back with a white, braided rope.

Yes.
