Work Text:

“You made the right decision, Kiyo,” says his boyfriend, caressing Kiyoomi’s cheek with the back of his slim fingers. “It will be amazing, I’m sure of it.”

Kiyoomi gives a smile that doesn’t quite match the smug smirk on Kenji’s face.

“We don’t even know if he’ll say yes to our request.”

Kenji snorts. “Miya saying no to sex? Never. Judging by the rumors, he’d screw anything with a heartbeat. And you’re stunning, Kiyo..he won’t refuse. Just let me handle the talk.”

Right. Miya Atsumu sure had a reputation for sleeping around. Even in his own classes, Kiyoomi had heard people talk about the blond campus fuckboy.

He would usually not pay much mind to immature gossip like this, but he couldn’t deny that his curiosity was piqued after catching snippets of the bedroom talk here and there.

So the blond man had been the first one that came to Kiyoomi’s mind when Kenji had brought this whole thing up a few days ago. But now that he was on his way to their apartment, he wasn’t so sure anymore. Miya was…a walking headache.

They had never talked, but Kiyoomi had seen him at parties a few times and in his freshman year they had been in a few classes together. He doubts that Miya would recognize him, but in Kiyoomi’s head a clear image of the other had formed over the years.

A loud and obnoxious guy that struts around like he owns the whole campus,a perpetually cocky grin plastered on his face. He was undeniably handsome with tousled blond hair and a body that matched all the gym pictures and thirst traps on his instagram.

He was the exact opposite of the calm and mature Kenji. Maybe it was because he was a few years older than Kiyoomi, but his demeanor and the way he carried himself were very different from most men around them.

That might have been what had drawn Kiyoomi to him in the first place. They had been dating for two years now, having met back when Kenji used to be the tutor of his first-year economics class.

Kiyoomi had never been the type to enjoy the loud and chaotic parties on campus so he liked being with an academically esteemed and wealthy man like Kenji. Instead of having to sit between sweaty and screaming students reeking of alcohol while the volume of the music threatened to pierce his eardrums, Kiyoomi could visit the best restaurants in town and build connections with important figures at various cultural events Kenji took him to.

His boyfriend was the perfect gentleman in every sense, which is why the request he brought up a few days ago had surprised Kiyoomi a lot.

Kiyoomi couldn’t compare him to past partners since Kenji was the first person he ever got intimate with, but so far his boyfriend had seemed like he was content with their sex life and didn’t show any intention of experimenting with anything.

Even if he brought something up, Kiyoomi would have expected him to request a special outfit or a difficult position and not… He would have never guessed that the composed and polite man had a voyeurist side to him.

Just the thought of Kenji wanting to watch other people having sex already made Kiyoomi blush, but knowing that he wanted someone else to do those things to Kiyoomi while he himself is watching was quite the shock to Kiyoomi. It was a filthy image, but Kiyoomi couldn’t deny that the thought excited him too.

He never told Kenji about it, but he had always felt like something was missing when they had sex. He was scared to bring up the topic though, since Kenji didn’t seem to have any complaints.

If it was Kiyoomi who didn’t manage to come most of the time, the problem had to be him, right? So maybe this little change in the bedroom would play out well for them both. Also, he loved Kenji and wanted to be good for him.

The problem was finding someone that was suitable for the job. Since Kenji had a reputation he needed to protect, it wouldn’t be wise to pick just anyone that was willing. Most people wouldn’t want to be part of something like this at all and others might use it against them in the future.

“How about that Miya guy?” Kenji had said that night.

“Huh?” Kiyoomi asked, brows raised in surprise at hearing the name that had popped into his own head right away. “Why him?”

Kenji rubbed his chin as he paced around the room. “He’s a total slut, so I doubt he would have issues with the..moral aspects of our request. And the other thing..He doesn’t seem like the kind of person that would blackmail others with this. He probably did much worse things already.”

For some reason Kiyoomi was convinced of that too, so after some more discussion they had decided to go with that option. Through one of his friends Kenji had arranged a meeting with Miya to discuss their proposal and right now he was on his way to Kenji’s apartment on campus.

The shrill ringing sound of the doorbell makes Kiyoomi flinch, wide eyes staring up at Kenji who quickly walks to the bedroom door.

“You wait here while I talk to him,” the man says, stepping out into the hallway. “You should be able to hear us well, I’ll leave the door open. I’ll call you when needed.”

Kiyoomi nods and listens to the footsteps moving towards the entrance door.

“Welcome, Miya-san. Please come in.”

“‘Sup..” a deep voice answers lazily.

Kiyoomi swallows through the lump in his throat, quietly getting up and walking over to the door to hear better. He catches sight of a red hoodie that disappears around the corner just then.

The musky scent of cologne fills his nose when Kiyoomi sticks his head out into the hallway. It definitely is a cheaper brand than what Kenji usually wears, but the scent is nice and alluring. Without realizing it, Kiyoomi takes a deep breath.

There’s the shuffling sound of the two taking their seats in the living room, then Miya’s booming voice speaks up again.

“Alright, Kento-kun. My friend said ya have urgent business with me. So..here I am! What can I do for ya?”

“My name is Kenji…,” Kenji replies, Kiyoomi’s lips curl up at the clear irritation in his voice. “Yes, I indeed have something important to discuss with you, Miya-san. Thank you for coming to see me.”

Kiyoomi notices his quick heartbeat, taking a deep breath and tightening his grip on the doorframe.

“I guess we both are aware of the reputation you have on campus…You sure have been enjoying yourself with all kinds of people.”

Miya draws in a sharp breath at that.

“Fuck, don’t tell me I slept with yer girlfriend. I swear ta god, if this is another of those-”

“No, this isn’t about something like that,” the other interrupts him. “You have no need to worry. I just have a suggestion that might be of interest to you.”

“Oh, alright,” Miya laughs out, audibly relieved. “That’s good. I’ll meet a real cutie tonight and a bloody nose would be a major turnoff.”

Kiyoomi raises a brow. Just what on earth had Miya been up to lately?

“Then what is that suggestion that might interest me?”

Kenji clears his voice and begins to speak once more. “My partner and I want to try out something new in the bedroom. To tell the truth, the sex with him hasn’t been very satisfying lately, even boring at times.”

Kiyoomi’s brows draw closer at this, his chest twisting painfully.

“Have ya asked him what he likes?” Miya drawls back, not seeming fazed by the question at all. “If the sex is not satisfying to ya, it’s probably not good for him either. It’s much more fun if ya keep yer partner’s pleasure in mind. I can help ya with that, though..Tell me about him.”

“I didn’t call you here to ask for advice,” Kenji returns in a cool manner. “My request is more…physical in nature.”

“Oh?” Miya makes a surprised noise. Kiyoomi hears the sound of fingers digging in a bowl, Miya helping himself to the peanuts on the couch table. “This is takin’ an interesting turn. I’m all ears.”

“Alright…There’s something I have been fantasizing about for a while. And now that our sex life is starting to bore me, I thought it’s the ideal time to finally invite someone to join us in the bedroom and….give us what we need.”

“So a threesome?” Miya smacks his lips. “Sure, why not? I’ve had many of those…I won’t take it up the ass though, ya should get someone else for that.”

“You won’t have to. In fact, I’ll be taking a passive role in the whole thing. It’s just you and him.”

The room falls silent after that, the sound of the hand fishing out some more peanuts is the only thing Kiyoomi hears for a while. Then Miya finally speaks again, Kiyoomi can clearly imagine the smug grin on his lips.

“So ya get off on watching other guys fucking yer boy? For real?”
Kiyoomi bites his bottom lip nervously, holding his breath.

“Would you be interested or not?” Kenji pushes impatiently. “You don’t need to comment on anything else.”

Miya chuckles, popping some more peanuts in his mouth.
“I can’t say that I’m not, it sure sounds fun…But I’ll still have to refuse, sorry.”

“Why?”

“Come on, this just reeks of danger..” Miya explains, voice more serious now. “Messin’ with ya’ll rich guys isn’t good. If I fuck some random guy’s girl, I’ll be beat up by him and his friends in the worst case. But if I screw with the precious little playtoys of ya rich people, hell knows where I’ll end up.”

Kiyoomi frowns, not knowing what angered him more: being called a playtoy or the fact that Miya refused.

“Nothing of that sort will happen,” replies Kenji in a bored tone. “It’s me asking you to do this, after all. As long as you stick to the conditions, I have no reason to get upset with you. On the contrary, I’ll owe you one.”

Kiyoomi waits with bated breath, but none of them says something for a few seconds. Miya seemed to be thinking about the pros and cons of their little experiment.

“No, sorry. I don’t think it’s worth it for me,” Miya sighs. “I’m sure ya can find someone else. Sorry for wastin’ yer time, but I’ll leave now.”

“Wait a moment,” Kenji quickly stops him. “Kiyo! Come in.”

Kiyoomi jumps in surprise, he didn’t expect to be called. Miya had refused, so what use was there now? It feels awkward joining the two in the living room after all they had discussed, a faint blush on his cheeks when he enters the room and meets Miya’s gaze.

The other man was sitting in the armchair opposite of them, the blond hair hidden under the backwards turned cap. He was wearing black sweats and a red hoodie, the bright color looking good against his tanned skin.

The moment he sees Kiyoomi, Miya’s brown eyes widen behind the golden pair of glasses he was wearing. Kiyoomi almost missed the sudden darkness flickering across Miya’s eyes, it was gone so fast that he wasn’t sure if he had just imagined it, but it still sent a shiver down his back.

The blond watches Kiyoomi with an unreadable expression until the inky black eyes avert his gaze and Miya leans back in his seat.

“Still want to leave?” Kenji asks, a knowing smirk pulling on his lips.

Miya scratches the back of his neck, releasing a deep sigh. Finally, he looks back to Kenji.

“Fine. What are yer conditions?”

Kenji’s lips form a satisfied smile at those words.

“Not much from my side. I’ll just have you sign something next time. I hope you understand why I have to go that far..Absolutely no one can find out about any of this.”

Miya shrugs, not seeming surprised at all. “I like that actually,” he adds with a nod. “I also don’t want anyone to know. Don’t want them to think I’m some weirdo.”

Kenji’s eyes narrow for a second but he doesn’t comment, turning his head to the other man still standing next to him instead.

“Well, that’s all from me. Tell him your conditions, Kiyoomi.”

Kiyoomi looks from Kenji’s bored face to Miya’s intrigued one, licking his lips nervously. He hadn’t expected it all to be so formal. Miya patiently waits for him to start speaking.

“Uhm, just…,” Kiyoomi begins, swallowing at the intensity of Miya’s gaze on him. “Don’t do anything weird. Like hitting or choking me, it shouldn’t hurt.”

“Of course,” Miya nods. "Anythin’ else?”

Kiyoomi thinks for a moment. “Don’t kiss me either.”

Miya tilts his head at that, as if wanting to say something but he smirks instead and answers: “Alright. No kissing.”

Kiyoomi was trying to think of something else he wouldn’t want, when Kenji spoke up again.

“Are you clean?”

“Of course!” Miya assures with a lazy grin. “I always keep little Tsumu wrapped. I can get ya proof from the clinic if ya wanna go raw. I’d ask ya to do the same though.”

“Come inside,” Kenji orders. “Don’t pull out.”

Miya’s brows rise even higher than Kiyoomi’s own. “Damn, Kento, yer a real freak, aren’t ya?”

Kenji doesn’t say anything, just keeping his calm gaze on Miya who looks up at Kiyoomi now.

“Sure, I wouldn’t mind, but ya shouldn’t be making that decision…” Brown eyes meet black ones before they can look away again. “Omi-kun,” Miya speaks slowly. “Are ya okay with all that?”

Kiyoomi never really liked it when Kenji finished inside him, it was so messy and a real piece of work to clean, but before he realized it he had replied already.

“Yes, it’s okay for me.”

Kenji seemed more than content with that reply, gently caressing Kiyoomi’s back.
“You can come more than once, the more the better.”

Miya frowns a little, meeting Kiyoomi’s gaze for a second before looking back at the older man. “What about him?” the blond man asks.

“What do you mean?” Kenji gives him a confused look.

“Don’t you want me to make him come?” Miya adds, gesturing at Kiyoomi.

“Oh,” is all Kenji returns, looking up to Kiyoomi who lowers his gaze, clearly uncomfortable with the current topic. “Yes, of course. Just do your thing.”

Miya smirks, letting his eyes roam over Kiyoomi hungrily. “Oh, trust me, I will.”

Kiyoomi can’t help but blush, watching Miya rising to his feet and throwing the gray gym bag over his shoulder.

“If there’s nothin’ else ya want to discuss, I’ll leave now. Just tell me when and where ya want to get it done and I’ll be there.”

“How about this Saturday?” Kenji suggests, also getting up to lead Atsumu out. “There’s a party on campus so most rooms should be empty, we’ll have to worry about distractions less. And if it’s alright with you, we’ll come over to your place.”

“Saturday is fine,” Miya agrees, throwing another glance at Kiyoomi before he follows Kenji out of the living room. “Wouldn’t your apartment be the safer choice though? I’m sure my roommate will go to that party, but still..”

“It would fit my…my fantasy better if it’s in your bedroom.”

Miya stares at him for a second before a knowing smirk pulls on one corner of his lips.

“I see. Ya can’t wait to see me dragging him into my cave like some Neanderthal, right? Whatever gets ya off, bro. Fine, then Saturday at my place.”

Before Kenji can close the door, Miya winks at Kiyoomi with a playful grin on his lips. “Lookin’ forward to seein’ ya again, Omi-omi!”

They’re back in the bedroom when Kenji shakes his head to himself. “What an unpleasant guy.. but at least he’s attractive.”

Kiyoomi doesn’t answer and just sits down on the bed.

Kenji joins him and starts kissing his neck and Kiyoomi hums, turning around to him. Kenji quickly catches him in a greedy kiss.

“You’re amazing, thank you for agreeing to all this, darling,” the man whispers, pushing Kiyoomi down until he was lying on the bed. “It’ll be so good, so hot..shit, I can’t wait.”

Kiyoomi smiles, running his hands through the soft brown hair. He was happy he could do this for his boyfriend, it would be a nice change for them.

Maybe Kenji had been right and their sex really wasn’t as enjoyable lately. It probably was due to Kiyoomi’s lack of experience, Kenji had been in lots of relationships before him after all, no wonder he got bored. He wanted to learn more and be better for him.

“You’re so beautiful,” Kenji smiles down at him before pushing himself off the bed and grabbing his phone off the nightstand.

“Get undressed and prepare yourself, alright? I’ll order us dinner and take a quick shower.”

It always went like that, so Kiyoomi doesn’t know why he felt so dirty this time, struggling to open himself up on the big bed. It stings when he tries to hurry and he hisses out in pain, hating this part of sex the most.

When his thoughts start wandering off to the large hands he saw earlier and he starts imagining what it would feel like to be held by them soon, it starts getting easier. Before he knows it, he’s moaning into the darkness of the room, his mind full of cocky grins and piercing brown eyes.

#

It takes a while for Miya to open the door.

When he finally lets them enter, they follow him to the room at the end of the hallway. Kiyoomi’s eyes roam around curiously. The room is small but neat, there’s not much stuff lying around except for dumbbells on the floor in front of the closet, an old volleyball in a corner and some books stacked on the desk. It smelled clean, like fabric softener and soap.

Miya had a white towel around his neck and his blond hair was still a little damp from the shower. He was wearing gray sweats and a simple white shirt, the hint of a shimmering gold chain catching Kiyoomi’s eye.

“Ya can sit there,” Miya nods over to the chair he had prepared for Kenji before letting himself flop down on his bed, throwing the towel across the room into the laundry basket. He supports himself on his elbows, grinning up at the flustered Kiyoomi from the bed.

“Ready when you are, Omi-kun. Do ya want to take a shower first?”

He shakes his head. “I showered before we came here.”

“Alright. Then c’mere,” he chuckles, patting the spot next to him. “I don’t bite.”

After hesitating for a second, Kiyoomi slowly walks over to Miya and sits down next to him.

“Lie down and make yerself comfortable.”

Kiyoomi nods and shuffles further up the bed, cheeks heating up when he sees all the towels Miya had prepared. When he looks up and meets Kenji’s gaze, a shiver runs down his body at the hooded eyes that stare back at him. Suddenly he feels self-conscious, curling in on himself.

“Hey, don’t look over there,” Miya draws his attention back to himself. “It’s just us two now, okay? Pretend that he isn’t here.”

Then he turns his head back to Kenji. “The same goes for ya. Don’t interrupt us and stay quiet. That’s my only rule. I don’t like it when they aren’t fully with me.”

“Understood,” is all Kenji says.

When Miya looks back at him, Kiyoomi nods too, lying down flat on the bed to not see Kenji anymore. He notices that his fingers are shaking when he tries to open his pants in a hurry, he still had to prepare himself after all.

“Relax, we have enough time,” Miya laughs, before climbing on the bed too. “And it’s easier if I do that, ya can just lie back.”

Kiyoomi halts his movements and looks up at him, the other peeling the jeans off him with practiced ease before moving on to the buttons of his blue shirt, swift fingers undoing them one by one.

“Ya said ya don’t want to be kissed,” Miya starts, locking eyes with Kiyoomi. “Should I avoid kissin’ ya entirely..Or are other spots okay as long as it’s not on the lips?”

Before Kiyoomi can raise his head to look at Kenji, Miya pushes him down with one hand, raising his brows in warning.

“Eyes on me. Don’t forget our rule, Omi. I’m askin’ ya, not him.”

Kiyoomi looks back at him.
“I don’t want you to kiss me on the mouth…anywhere else is okay.”

Miya licks his lips before flashing him a pleased grin. “Great.”

Kiyoomi is freed of his shirt now and Miya lets his hands run over the pale skin, using his thumb to trace lines between the moles. When his fingers graze a nipple, Kiyoomi draws in a sharp breath, quickly biting his lip.

“Cute,” Miya smiles. “Yer moles are so pretty, Omi. I love them.”

“T-thanks,” Kiyoomi replies, painfully aware of his unclothed state now. “Can you please take your clothes off too, Miya-san?”

Miya snorts at that. “We’re about to fuck, Omi..I think we can skip the formalities..Just call me Atsumu.”

“You’re right,” Kiyoomi answers, embarrassed. “Atsumu.”

The blond complies and pulls the shirt over his head, throwing it across the room carelessly.

No wonder the man posted shirtless pictures all the time, who wouldn’t with a body like this? Lean muscles ripple under tanned skin, the gold chain dangling over his collarbones as he hovers over Kiyoomi, supporting himself with his arms.

“Like what ya see?” Atsumu asks, winking down at him before leaning down and pressing a kiss to his neck. “I enjoy my view a lot…Relax, Omi. Let me take care of ya.”

Only then does Kiyoomi notice how tense he was, lying there stiff as a board. He tries to calm his nerves and focuses on the feeling of Atsumu’s lips on his body. It felt better than expected, hot breath tickling his skin as the other man whispered praises after every kiss.

It doesn’t take long for Kiyoomi to melt into the bed, moaning out in surprise when he feels Atsumu’s tongue licking over a nipple. Mortified at his own sounds, he covers his mouth with a hand, but Atsumu pulls it off right away, pinning it down next to Kiyoomi’s head.

“Let me hear those pretty sounds, they’re adorable.”

He proceeds to lick and nibble at Kiyoomi’s chest until it’s all puffy, the black haired writhing under him, little gasps and moans starting to fill the room.

Kiyoomi feels how hard Atsumu already is when he pushes his leg between Kiyoomi’s, the length pressing against his pale thigh. Atsumu doesn’t seem to pay it much mind though, still leisurely kissing and biting around Kiyoomi’s collarbones and shoulders.

It’s when Atsumu starts absentmindedly rutting against him while licking at Kiyoomi’s neck that Kiyoomi remembers he wasn’t prepared yet. Even with lube it would hurt like hell if he shoved it in like that, he had to get himself ready now.

He struggles to free his hand from Atsumu’s grip and tries to reach for the bottle of lube next to them.

“Stay still, Omi,” Atsumu breathes against his neck, voice much deeper now.

When Kiyoomi doesn’t listen and Atsumu hears the sound of the lube bottle opening, he stops his ministrations.

“What are ya doin’?”

Kiyoomi gives him a shy look, cheeks flushed as he replies.

“Give me a moment, I need to prep myself.”

“What?” Atsumu repeats, confusion written all over his face. “You don’t have to. I’ll do that.”

Kiyoomi stares up at him with a stunned expression. “You will?”

“Yeah, of course!” Atsumu nods. “Why wouldn’t I?”

When he realizes what this is about, Atsumu turns his head to give Kenji a disapproving look. Clicking his tongue, he returns his attention back to Kiyoomi.

“What a fuckin’ waste,” he hisses, snatching the bottle out of Kiyoomi’s hand.
While Kiyoomi slides off his boxers, Atsumu pours some lube on his finger.

“It’s much easier when yer partner does it for ya. Feels nicer too. Just lie back and enjoy it, Omi.”

Kiyoomi tenses up when he feels the cold lube against his hole, Atsumu prodding with a teasing finger.

“Relax, Omi,” Atsumu whispers. “It’ll feel good, I promise.”

Kiyoomi nods and closes his eyes, releasing a soft sigh when he feels Atsumu’s finger entering him.
Once Atsumu can push two fingers in without much trouble, he starts going faster, gently biting into Kiyoomi’s shoulder when he mewls in his ear.

“Yer so sensitive, it’s drivin’ me crazy, Omi,” he releases shaky breaths next to Kiyoomi’s ear. “It’s beyond me how anyone could willingly miss out on these sounds.”

Kiyoomi is gasping for breath, digging his nails into Atsumu’s back when he feels a third finger pressing into him, relishing in the additional stretch.

“Almost there, baby, just one more,” Atsumu reassures him, nibbling at Kiyoomi’s ear. “So cute, could eat ya up..So good for me.”

Kiyoomi releases shaking breaths, throwing his head back against the pillow with a yelp when Atsumu’s teeth are back on his chest.

He had never experienced something like this before, Kenji never even bothered to check if Kiyoomi was sufficiently stretched and would just shove his cock in as soon as he could take two of his fingers without wincing.

In contrast, Atsumu didn’t seem to mind that he himself hadn’t even been touched yet, taking his time with thoroughly opening Kiyoomi up. It was like he couldn’t get enough of seeing Kiyoomi whimpering under him, biting his lips as he kept his hooded eyes fixed on the boy’s face.

“Yer so pretty like this,” praises Atsumu against his neck, drawing another moan from him. “I really wish I could kiss ya now.. but this will have to make do.”

Kiyoomi sighs when Atsumu starts peppering his jaw with kisses. His thoughts wander off to his request from earlier and he starts wondering whether he should take it back. He had a feeling that Atsumu was an amazing kisser.

Before he could drift further down that line of thought, a particularly deep shove of Atsumu’s fingers makes him scream.

“Bingo!” Atsumu smirks, biting down on Kiyoomi’s collarbone before proceeding to rub his fingers against that same spot with fervor.

Kiyoomi cries out and thrashes around, trying to pull away from the onslaught of pleasure overwhelming his senses, but Atsumu keeps him in a firm hold. His hot tongue licks over the boy’s throat as he’s shoving his fingers in and out mercilessly.

Kiyoomi’s whines grow more desperate, the force of the thrusts making precum drip on one of the moles on his stomach.

“A-Atsumu, too much-” he moans, tears welling up in his eyes. It felt too good, he would go insane if this went on for much longer.

“Sto-uhp, enough. I’m gonna-”
A more pathetic sob breaks out of him and he feels Atsumu’s cock twitch against his thigh.

“Fuck,” Atsumu hisses out, finally stopping the movement of his hand and pulling off Kiyoomi. “The sounds ya make are so fuckin’ hot, Omi..That should be enough..I need to fuck ya now.”

“Yes,” Kiyoomi whines, putting his arms around Atsumu’s neck to pull him closer. “Please, I can’t wait anymore. Need you.”

Atsumu groans, quickly sliding his sweats off and pouring a generous amount of lube over his hard cock. Kiyoomi’s eyes go wide at the girth of it, drooling a little at the thought of taking all of that soon. Atsumu wasn’t much bigger than Kenji but definitely thicker, he would fill him up nice and well.

“Hurry up, Atsumu,” Kiyoomi begs, gasping for breath. “Please..Fuck me now.”

“Shit, alright, I got ya,” Atsumu growls, pushing his knees between Kiyoomi’s legs to keep them open before lining his cock up with Kiyoomi’s hole.

Kiyoomi holds his breath when he feels the head against his entrance, his heart beating faster. But Atsumu isn’t moving yet, taking his time drinking in the view beneath him.

Soft black curls frame Kiyoomi’s flushed face as he gazes up at the other with big black doe eyes, chest rising and falling with impatient breaths. Atsumu’s eyes crinkle up in a fond smile when he spots the little pout on the boy’s lips.

“Alright, alright. I’ll start now, don’t give me that look,” he chuckles, shuffling closer. “Relax for me, okay?”

Kiyoomi nods, shivering when Atsumu’s big hand grabs onto his waist as he’s pushing in. He bottoms out with a deep thrust and Kiyoomi sees stars.

“Oh god,” he gasps, gripping the sheets below him. “Fu- A-Atsumu!”

Atsumu fucks into him at a fast pace, not giving him any time to adjust to the new size. “W-wait,” Kiyoomi manages to get out. “Slow down..or I’m gonna-”

“Shit, Omi, yer tight,” Atsumu breathes out, a deep moan falling from his mouth. “Feels amazin’, fuck.”

He rocks his hips forward with even more force when his eyes are back on Kiyoomi’s face. Atsumu hits his prostate with every thrust, pulling one sound after the other out of the boy.

“It’s too-,” pants Kiyoomi, his vision going blurry at an especially hard thrust. “Too much..so deep.”

“Yer doin’ amazin’, baby..,” Atsumu soothes. “Let me see ya comin’ for me!”

A few more thrusts and Kiyoomi was already thrown over the edge, crying out in surprise when his orgasm washes over him. He tries to muffle the moan that escapes him, but Atsumu is quicker and pins his hands on the bed. The cries that break out of him seemed to be coming from someone else, the sounds utterly foreign to Kiyoomi.

Hot streaks of cum keep shooting out of his cock as Atsumu fucks him through his orgasm. He doesn’t remember ever coming this hard before, his body twitching with every shallow thrust feeding fire into his core. The blond groans at the way the black haired clenches around him, rolling his hips in slow circles until Kiyoomi is finished and falls back into the bed in exhaustion.

“Shit, ya really came untouched,” Atsumu says, pupils blown wide in awe. “Yer perfect, Omi..The prettiest little fucktoy, aren’t ya?”

Kiyoomi moans at those words, his toes curling when Atsumu starts moving his hips again. He was still coming down from his orgasm and yet Atsumu isn’t holding back at all, strong thrusts hitting Kiyoomi’s prostate until he whines from overstimulation.

“Atsumu, fuck-,” he sobs, hot tears rolling down his cheeks. “I can’t. It’s- too much. Too good..ahh!”

Atsumu’s hips falter for a second before he’s groaning and leaning down to lick at the fresh tears staining Kiyoomi’s flushed cheeks.

“Fuck, look at ya,” Atsumu whispers, voice reverent as his dark eyes scan over Kiyoomi’s face greedily, as if trying to engrave every detail of it into his brain.

“‘Boring’, my ass,” the blond sighs, hips hitting against Kiyoomi’s ass hard enough to bruise, making Kiyoomi yelp. “Yer a dream, Omi.”

Kiyoomi is already fully hard again, a series of choked moans knocked out of him as he gives in to the pleasure, freeing his hands to bury his fingers in Atsumu’s soft hair.

Even though they were about the same height, he feels so small caged under Atsumu like this. The man’s dominating presence overwhelmed all his senses. The heat of his breath on Kiyoomi’s neck, the sound of his groans against his ear and that intoxicating cologne, Atsumu was everywhere. And Kiyoomi loved it, catching himself hoping that the bruises and marks Atsumu was leaving would stay on him for days. A shiver runs through him when there’s the low rumble of Atsumu’s laugh against his throat.

“What could be more important than watching this?” Atsumu chuckles.

“Huh?”

Kiyoomi needs a moment to realize Atsumu wasn’t talking to him, but to Kenji.
The man was standing at the door with his ringing phone in his hand, about to step out into the hallway.

Right, Kenji. Kiyoomi lets out a little gasp, clenching around Atsumu in shock and making him suck in a sharp breath and stop his thrusts.

“Fuck, Omi-”

Kiyoomi had forgotten about his boyfriend entirely, the sudden realization makes him hyper aware of the exposed state he was in. He’s mortified, remembering all the embarrassing sounds he had made so far. Ears glowing pink, he hides his face in Atsumu’s chest.

“It’s a call from a business partner, I need to take that,” Kenji replies calmly, as if he hadn’t been watching another man railing his boyfriend just now. “Please excuse me, just keep going.”

When the door closes behind him, Atsumu scoffs in irritation: “What’s wrong with this guy? He’s like a robot, makes me sick.”

Kiyoomi couldn’t help but giggle at the disdain on Atsumu’s face, the blond turning his gaze back to him and lifting his brows in surprise. His lips twitch into a fond smile as he watches Kiyoomi who can’t stop giggling.

Atsumu looks beautiful, flush barely noticeable on his tanned face, some blond strands sticking to his sweaty forehead. Without thinking, Kiyoomi lifts a hand to brush the hair out of his face. Atsumu’s gaze moves from Kiyoomi’s eyes to his lips, then he’s slowly leaning down. Black eyes widen, Kiyoomi’s heart skipping a beat in his chest.

But just when Atsumu’s lips are hovering over Kiyoomi’s, he seems to remember their agreement from earlier and he huffs in frustration, dropping down to kiss up Kiyoomi’s neck instead.

“Where were we?” his deep voice whispers next to Kiyoomi’s ear before he snaps his hips forward again, making Kiyoomi moan and hug Atsumu closer.

Kiyoomi can’t help but notice the disappointment gnawing at him. Why did Atsumu not kissing him bother him so much? He had requested that himself, so he had no right to get annoyed over it.

He’s quickly pulled out of his thoughts by a deep roll of Atsumu’s hips. “Ah!” Kiyoomi gasps, dropping his head back on the pillow.

Atsumu’s pace was changing, as if he was trying to hold off on his orgasm. Kiyoomi notices him switching from quick thrusts to more languid movements, sometimes stopping entirely to pepper Kiyoomi’s chest and neck with kisses.

“I noticed ya long ago, Omi….”

Kiyoomi’s brows jump up at that, a surprised sound escaping him.
Atsumu laughs huskily, smiling against his neck.

“Yeah, saw ya at a party in yer freshman year..Always thought of how pretty ya would be moaning under me, but, fuck, reality is so much better than any fantasy. Shit, Omi, baby..”

Kiyoomi shivers when Atsumu thrusts deeper into him, his rhythm faltering.
“Yer way too cute to let yer man lend ya out like some whore.”

Atsumu must have noticed Kiyoomi’s cock twitching at those words, raising his head to look at Kiyoomi who was averting his gaze, blushing pink.

“Fuck, ya like that?” Atsumu whispers, breathless. “Ya like being called a little slut? Wanna be passed around like this?”

Kiyoomi can’t help the moan that leaves him, Atsumu’s cock pressing against his prostate in that exact moment. It turns into a string of whimpers when Atsumu starts putting more force into his thrusts, knocking the air out of Kiyoomi as he’s held in place by Atsumu’s strong arms around him.

“‘m close,” Atsumu growls.

In the next second Atsumu lets go of him and pulls out.
Kiyoomi whines at the loss, but before he can complain, Atsumu quickly flips him over and slides back in. Kiyoomi cries out when he’s jolted forward, Atsumu pulling him right back to meet his thrust halfway.

“If ya were mine…fuck-,” Atsumu groans, pinning Kiyoomi’s wrists on the bed as he fucks into him relentlessly.

“I would snap their necks before I let anyone lay a single finger on ya.”

Kiyoomi squirms under him, he could feel another orgasm approaching and in this position he couldn’t even fight it, Atsumu’s thighs keeping his legs spread wide and making it impossible for him to escape those punishing thrusts.

“A-Ah- Atsumu,” Kiyoomi pants, voice hoarse from all the crying. “More..”

Atsumu’s hold on Kiyoomi’s wrists is almost painful, deep groans and the sound of skin slapping against skin filling the air as he starts going faster.

“Ya wouldn’t need anyone else again..,” Atsumu gasps, voice heavy with need. “I’d keep yer tight little hole nice and full like this, treat ya like ya deserve, baby. That loser can’t even fuck ya right, can he? He’s a fuckin’ idiot for lettin’ anyone get their hands on yer pretty skin- but hell, am I lucky! So cute.. the prettiest.”

Kiyoomi’s second orgasm hits him like lightning, a loud scream leaving him as heat floods through his body. Atsumu doesn’t slow his thrusts, forcing more and more cum out of Kiyoomi who quickly goes limp on the soiled towel, gasping for breath. He’s spasming and drooling with each thrust, but still taking everything Atsumu is giving him.

“Shit, I’m gonna come,” Atsumu’s hissing as he pounds into Kiyoomi’s abused hole. “Gonna fill ya up, Omi baby..Pump ya so full yer freak boyfriend won’t believe his eyes.”

When he looks down, Kiyoomi has his head turned to him, big doe eyes blinking up at him in a daze. Atsumu’s mouth falls open, his hips stuttering for a second. He wants to say something, but then Kiyoomi is hooking a finger onto Atsumu’s gold chain and pulling him down into a kiss.

Atsumu’s brows raise in surprise at first, but when Kiyoomi doesn’t pull off, he wastes no time in licking into his mouth while he keeps fucking into Kiyoomi. The black haired is humming into the kiss, his heart swelling in his chest and little moans escaping him with each sinful thrust Atsumu feeds into his pliant body.

It doesn’t take much longer until Atsumu is coming with a groan, rolling his hips even deeper into Kiyoomi. Kiyoomi is sighing into the kiss when he feels Atsumu’s hot cum filling his ass, heat spreading through his whole body. He mewls as thick streaks of cum keep flooding his walls, Atsumu's orgasm seeming to go on forever. His heart does a little jump at the thought of getting marked by Atsumu like this.

They keep kissing each other, the silence in the room only broken by soft gasps and little moans. Kiyoomi didn’t know that sex could be this good. He feels like he’s floating, his heart beating faster at every sound Atsumu made, tears welling in his eyes when calloused fingers intertwine with his, squeezing them tightly. He feels safe, cherished, adored.

He wonders if Atsumu’s past sex partners had also felt like this, if he had treated them with the same devotion. Kiyoomi senses an ugly monster forming inside his stomach at these thoughts, digging its dark claws into his organs and baring its long fangs as it roared with hatred.

He’s licking into Atsumu’s mouth with more greed, Atsumu groaning against his lips and pushing deeper into him. They break apart to take deep breaths, a small frown pulling on Atsumu’s brows when he looks in Kiyoomi’s black eyes.

“Omi, I-.”

“-yo..Kiyo!”

Kiyoomi flinches, lifting his gaze to Kenji who was standing next to the bed, arms crossed impatiently.

They hadn’t even realized that he had come back to this room, both of them looking up to the man without a word, still trying to catch their breaths.

“Hurry up and get dressed, we’re going home.”

When Kiyoomi looks back at Atsumu, the blond’s gaze is hazy. After a while, he reluctantly pulls off Kiyoomi and gets up to put his pants on.

Kiyoomi shivers, taking the clothes Kenji is handing to him before letting himself get pulled up from the bed. He’s wobbly on his legs, slowly getting dressed while Kenji was gathering their things.

“Did ya enjoy the show, Kento-kun?” Atsumu sneers, clear contempt in his eyes when he watches Kenji throwing Kiyoomi’s jacket at him. “Ya could’ve at least let me clean him up, ya know?”

“It’s okay like that,” Kenji replies curtly, visibly agitated. His eyes run over Kiyoomi’s disheveled state, gaze turning darker with every second. He licks his lips when he takes in the mess on Kiyoomi’s thighs. “He can do it later. I want to get him back into my apartment now.”

Atsumu rolls his eyes, leaning against the wall and watching Kiyoomi struggling with the buttons of his shirt. When Kiyoomi looks up and catches him staring, he quickly averts his gaze.

“I’ll be waiting in the car, Kiyo,” Kenji calls out, strutting towards the exit without sparing Atsumu another glance. “Be quick.”

“What a fuckin’ prick,” Atsumu spits angrily before Kenji was even fully out the door.

Kiyoomi lets his eyes roam over all the red lines on Atsumu’s arms and chest that hadn’t been there before. When Atsumu catches Kiyoomi’s gaze, he raises a brow at him.

Kiyoomi lowers his gaze, swallowing through the lump in his throat. He had to get out of here.

“..Goodbye Miya-san,” Kiyoomi mumbles, heading to the door. Atsumu doesn’t say anything.

Before Kiyoomi can reach the door, however, he feels a warm hand wrapping around his wrist, pulling him back into a firm chest. Kiyoomi’s breath hitches when he feels Atsumu’s hot breath on his neck, his deep voice sending shivers down his spine.

“If ya ever want to do this again…Ya know where to find me, Omi,” he breathes against the back of Kiyoomi’s neck, putting a featherlight kiss there.

“But next time, leave the boyfriend at home,” Atsumu adds with a smirk.
