Friday, September 5th, 10:25pm

oikawa-san: ok!! the doors unlocked!

oikawa-san: dont be too surprised when u come in ☆ ~('▽^人)


It had been a little over a month since Kageyama and Oikawa had hooked up--both of the two were caught up with schoolwork--but with both of their teams being invited for some Tokyo training camp, and with them being in the same hotel building, they finally had a chance to relieve some stress.

Although, Kageyama found himself standing still in front of the door, a hand frozen on the doorknob. Underneath his bathrobe, he was wearing a two-piece set of black lingerie, a bunny headband stuffed into his pocket, but that wasn't the reason why he felt so hesitant.

It was because he could hear the sound of skin slapping against skin, and Oikawa's moans...

Kageyama peered through the peephole of the door, and flushing red, he saw Oikawa, completely naked, twisted onto his side while Atsumu pounded into him, hard. Oikawa was at the edge of the bed, and Atsumu was standing on the floor, so he was completely taking advantage the leverage he had over him.

And to be honest, it turned Kageyama on way more than he wanted it to.

Accidentally, Kageyama leaned on the door a bit too much, causing it to swing open slightly. He bit his lip, hearing the sounds of the two stopping.

Fuck. Fuck.

"Tobio-chan?" Oikawa's voice was breathy, sounding so, so fucked out. "So nice of you to join us."

Kageyama realized there was no turning back now, so he tentatively stepped into the room, shutting the door behind him. And god, Oikawa looked perfect like this, his face flushed, hair plastered to his forehead from sweat, covered in newly-formed hickies and bruises. The only thing stopping him from rushing over to him and kissing him hard on the mouth was Atsumu--his gaze that was locked on him seemed as if he wanted to burn a hole into him.

"Oi-Oikawa-san," Kageyama started. "Um--"

"Oh, Atsu-chan wanted to join us!" Oikawa gave him a weak smile, mind still clearly fogged by the pleasure of sex. "I hope you don't mind?"

"I..." Kageyama's voice trailed off. He felt way too flustered. "I..."

"I get it, Tooru," Atsumu interrupted, slowly pulling out of him. Kageyama's gaze rested on his cock, and he flushed at the memory of when he'd deepthroated him in the storage room. "Tobio-kun's just a little embarrassed. He thought it'd just be you and him. And you know him, being a goody two shoes and all--the thought of a threesome never crossed his mind."

"Atsumu." Kageyama was sure the embarrassment he felt was going to kill him. "I'm not a--"

"Goody two shoes?" Atsumu tossed the thought in his mind for a moment, stroking his cock lazily. A smirk formed on his lips. "You're trying so hard to be someone you're not."

Kageyama swallowed hard, standing still as Atsumu walked over to him. The latter slid his hands underneath the former's bathrobe, his fingertips playing with the lace that covered his nipples, smiling cruelly as he squirmed, until finally, he removed the robe for him. Atsumu whistled, squeezing his ass with one hand.

"Looks like Tobio-kun wanted to surprise you, too."

Oikawa propped himself up on his elbows, his eyes twinkling at the sight. His gaze trailed down lower and lower, until--

"Oh? There's something that fell out of his pocket."

Kageyama's cheeks burned as Atsumu bent over, picking up the headband; burned as he put it on for him, gripping his jaw with one hand as he admired him with a coo.

"Tooru," Atsumu began, letting go of Kageyama to turn to Oikawa, "it looks like he wanted to be pretty, all for you."

Oikawa was clearly eating up the look, biting down on his bottom lip. "Aw--my precious baby."

Atsumu turned back to Kageyama, briefly looking over his dick that looked painfully hard, straining against the fabric. "Tobio-kun, if you don't want to do this, you can always say so, you know? And I'll leave. Easy as that."

But Kageyama's fists clenched, and quietly, he shook his head.

"No? You wanna stay?"

"Y..." Kageyama opted for a nod of his head instead. Atsumu looked pleased.

"Well, then, go ahead and fuck your upperclassman, then," he said. "I stretched him out, all for you."

"What about--"

"Me?" Atsumu walked over to a chair, seating himself on it. "I'll just... watch. For the meantime."

The very thought made blood rush south for Kageyama.

"Tobio-chan," Oikawa whined, patting a spot on the bed next to him. "Hurry up, I'm horny."

Mind buzzing, Kageyama climbed onto the mattress, hips immediately jerking as Oikawa palmed his erection, climbing between his legs.

"You look so, so pretty, baby," Oikawa murmured, and he placed his mouth over the bulge, sucking despite the thin layer of fabric between them. Kageyama's grip on the bedsheets was tight. "Dressed up, all just for me? My pretty, pretty bun."

"Oi-Oikawa-san," Kageyama breathed. He could feel the intense gaze of Atsumu--even though he wasn't speaking anything, there was something about his expression that screamed impatience. He fucking hated how much it turned him on. "Get on your knees."

"Of course, baby."

And as Oikawa put himself on all fours, and as Kageyama spread his cheeks apart, arousal rushed through his body as a bead of cum dripped out, running down his perineum.

Fuck. Fuck. Fuck.

"What's wrong?" Atsumu's voice rang from behind him. "So what, if I already came inside of Tooru? He can handle another one."

Kageyama squirmed as Atsumu sat behind him, hands moving to pull down his panties. Oikawa looked over his shoulder, half-lidded eyes gleaming.

Atsumu guided Kageyama's cock to Oikawa's rim, the latter whining as the hole closed around his cockhead without much resistance. He put his hands on Oikawa's hips, immediately beginning to move.

The squelches of cum and lube and pre-cum obscenely filled the air.

"Tobio-chan," Oikawa breathed. He clenched around Kageyama's length, making him yelp. "I missed the feeling of your cock so, so much, baby."

Kageyama opened his mouth to speak, but Atsumu's hands squeezed his ass, giving one cheek a hard spank.

Fuck. Fuck. Fuck.

"What's wrong, baby?" Oikawa teased. "Does my ass really make you feel that good? Can't even talk to me? Just wanna fuck into something wet and warm, you dumb slut?"

"Oi-Oikawa-san," Kageyama began, whining as Atsumu began to run his hands over his nipples. He shot him a glare, but the other only smiled in return. "I--I--"

God, the feeling of fucking into someone who was already filled with cum was too, too much. It felt so slick, and despite having already been stretched out, he was still so tight--the fact that Atsumu was also playing with his nipples also didn't help.


Kageyama had been so caught up in thrusting into Oikawa that he barely registered Atsumu pulling down his panties more, just so that it rested mid-thigh. Then, with one finger, somehow already covered with lube, he began to press against Kageyama's rim.

"A-Atsumu," Kageyama began, his hips beginning to stutter--he was caught up in a cycle between wanting to fuck into Oikawa or fuck back into Atsumu's grip, and it was so, so much. He grit his teeth, his grip on Oikawa's hips tightening. "Y-You--"

"Too much?" Atsumu asked, and Kageyama let out a small moan as the former bit his neck, sucking it slightly, his finger sliding knuckle-deep. "Poor little bunny fucks like one, but already gets overwhelmed when he gets fingered?"

A second finger slipped in, and fuck, he was about to cum way sooner than he wanted to.

"Are you already overwhelmed?" Atsumu continued, nipping the shell of Kageyama's ear, curving his fingers just slightly as the latter fucked wetly into Oikawa. His fingers were so, so close to his prostate--

"Of course," Oikawa said, answering for Kageyama. "Poor, poor slut gets overwhelmed so quickly; he can't help it. Right, Tobio-chan?"

When Atsumu slid in the third finger, twisting the digits deeper into Kageyama, the latter's eyes widened, and he came hard into Oikawa.

"Fuck," the oldest setter said, thighs twitching at the feeling of excess cum leaking out of his hole. (He had also came, dirtying the bedsheets with sticky whiteness.) "Fuck, baby, you feel so good--"

He had gotten caught off as Atsumu had quickly entered Kageyama, who was already shaking from post-orgasm, each thrust also causing him to also fuck into Oikawa.

Kageyama lay limply on Oikawa, trying his best to support himself to not crush him but it was so hard, sensitive cock fucking into Oikawa's heat, while his own rim was stretched wide by Atsumu's cock. He was so thick, maybe too thick, but god, he'd be lying if he didn't enjoy that stinging feeling of pleasure-pain. Oikawa was also overrun by the sensation, moaning loudly and incoherently as his prostate was rubbed well past overstimulation.

"Remember what I told you, Tobio-kun?" Atsumu asked after a particularly deep thrust. "That I'm gonna make sure you don't walk the next day?"

"All too well," Kageyama managed, staring at the accidental, red scratches he was marking on Oikawa's sides. "Fuck, Atsumu--"

It wasn't too long before Atsumu came into Kageyama, the younger setter whining at the feeling of cum painting his insides. He pulled out, and Kageyama did the same for Oikawa, collapsing tiredly onto the spot next to him.

Atsumu seemed like the only one who still had energy, smiling at his handiwork of the two others' exhaustion.


Kageyama flipped him off, gathering enough strength to sit up. "I'd be lying if I said I was satisfied."

At that, Oikawa laughed. "Who said there wasn't gonna be a round two?"



Kageyama was on all fours this time, mouth wide open as Atsumu fucked three fingers into him, while Oikawa was messily spreading lube all over his ass, all over the small of his back.

He felt filthy, so filthy.

"You're so fucking messy, Tobio-kun," Atsumu chastised, pressing down on his tongue. "Look--you've got drool all over your chin."

"Baby's always been messy," Oikawa called out from behind, smoothing over the lube on his skin, the movement slick and easy. He pressed his thumbpad against Kageyama's rim, cooing at the drop of cum that threatened to dribble out. "Isn't that right, bun?"

But Kageyama couldn't answer--could only suck on the digits in his mouth. With a tsk, Atsumu removed his fingers, using the same hand to grip the sides of his face, forcing his mouth open.

"Answer Tooru, goddamn it."

"Y-Yes," Kageyama managed. God, he was slipping so far into subspace now. "T-Tobio-chan's al-always been m-messy."

"Keep your mouth open."

Kageyama obeyed, whining as Atsumu spat into his mouth, eyes widening as he suddenly felt Oikawa's tongue on his rim, pushing past the opening and--

And licking out Atsumu's cum from his hole.

"S-Stop!" Kageyama protested, flustered, and Oikawa pulled away, squeezing his ass.

"What's wrong?" he asked. Even if Kageyama couldn't see his face, he knew he was smirking. "You want Atsu-chan's cum to stay inside you?"

The words burned, reddening his face with embarrassment, because it was absolutely true. Avoiding Atsumu's gaze, he nodded his head.

"Maybe this is why Tobio's so insistent on not being called a good boy," Atsumu said, grabbing Kageyama by his hair, forcing him to make eye contact. "Because all he is is a cumslut, right? Just a greedy whore, wants nothing else to be filled with cum and fucked silly, right?"

Kageyama's head was buzzing, buzzing.

"What about lube?" Oikawa asked, pressing the tip of the lube bottle into Kageyama's hole, coldness gushing into the latter as he squeezed it. "You like being messy, Tobio-chan? You--ah, god, you're leaking everywhere."

"S-Sorry!" Kageyama squeezed his eyes shut, biting his lip as he felt excess lube run down his thigh.

"So fucking messy," Atsumu muttered, pressing the tip of his dick to Kageyama's mouth. "But we'll train you to be a good boy. You want that?"

Kageyama was silent. Even with his head floating up in the clouds, the stubborn part of him still didn't want to completely admit to him how much he enjoyed being put into submission.

"Answer me."

Atsumu slapped his cock against the side of Kageyama's cheek, making the latter's cockhead leak a fat drop of pre-cum (Oikawa caught it with his hand, smoothing it over the tip of the youngest's dick).

"I..." Kageyama squeezed the bedsheets with his hands, so far gone. "I w-wanna be a good boy, just for you, just for b-both of you, and... y-yes, I want to be filled with cum, your cum, p-please, slut like me d... d-deserves it...!"

Atsumu swore under his breath, and with little warning, pushed his length into Kageyama's open, pliant mouth. Oikawa spanked the youngest's ass, before he also pushed past Kageyama's rim, the squelches of lube and cum filling the air as both began to thrust into him.

Kageyama's mind went numb, focusing only on keeping his jaw stretched wide as Atsumu fucked into his throat; focusing only on Oikawa yanking the garters of his lingerie back each time he thrusted into him. He was vaguely aware of the saliva that was dripping from his chin; vaguely aware of all the excess fluid that leaked from his hole, splattering on both his back and the bedsheets.

But then he felt a pressure around his dick, and it took him a moment to understand what it was until his eyes widened with realization.

Fuck, Oikawa's using a fleshlight on me. Fuck. Fuck.

"You're not gonna cum already, right, Tobio-kun?" Atsumu asked, and all Kageyama could do was moan in response. "But I'm not surprised if you are. Fucking cocksluts like you just want all your holes to be filled up--all filled up while your dumb cock fucks into something warm and wet, right?"

When Kageyama whined, Atsumu seemed to take some pity on him, pulling out of his mouth, tongue and cockhead connected by a string of saliva.

"Y-Yes, please--" He stopped himself, realizing he was on the brink of orgasm. "F-Fuck, Oikawa, I'm gonna--"

"Gonna what?" Oikawa asked with feigned innocence, pulling out of him, letting go of the fleshlight. "Gonna cum?"

Kageyama let out a petulant cry, pressing his forehead to the mattress. He tried grinding against the bedsheets, but Oikawa gave him a sharp spank in reply.

Fuck, I was so, so close--

Atsumu yanked him by the hair, and he pouted. "Tobio-kun's crying?"

Oikawa frowned. "What's your color, baby?"

"G-Green, I just--" Kageyama swallowed hard as Atsumu brushed away a tear with his thumb. "I just wanna cum, I was so close, please--"

"You're asking so nicely, as if you haven't been greedy," Atsumu said with a laugh, running a finger over Kageyama's swollen bottom lip. "Isn't that right, Tooru?"

Oikawa hummed in agreement, reclining back to rest on some pillows. When Kageyama turned his head to face him, he cheekily stuck his tongue out. "You gotta work for it, bun."

"W-Work for it?"

"Since you don't wanna be a good boy," Atsumu began, "you gotta work for it."

When Kageyama's face was still blank, Oikawa laughed, sitting up to plant a quick kiss on the other's mouth. "You're gonna have to ride me, is what we mean. Is that fine, baby?"

Eagerly, Kageyama nodded his head quickly, moving to straddle his hips. "Y-Yes, that's fine...!"

He guided Oikawa's tip up to his rim, pushing it slowly into him, but was caught off-guard when Atsumu placed both hands on his shoulders, pushing him down firmly, forcing him to bottom out in one go. Kageyama moaned, resting his forehead against Oikawa's chest as the latter whispered soft praises into his ear, gently removing his headband and setting it aside.

"You're doing so well, baby. You feel so, so good," Oikawa softly told him. "You're adorable, your thighs are shaking so much."

Biting Oikawa's collarbone, Kageyama slowly began to ride him, legs trembling as he moved up and down. He blushed, though, as Atsumu pulled apart his asscheeks; blushed as he felt a small gush of cum and lube drip down his perineum.

And then Atsumu slipped one finger in.

"A-Atsumu!" Kageyama started, but Oikawa slapped his cock.

"Never said you could stop, slut."

Kageyama whined in protest, but he obediently continued to ride Oikawa. His thighs were screaming from soreness.

A second finger slipped in.

Kageyama gasped, rutting against Oikawa for some sort of relief. Oikawa cupped his head with both hands, shaking his head in adoration. "Do we really make you feel that good?"

The youngest didn't reply--only leaned in for a sloppy kiss. Oikawa giggled, sucking on his tongue in return, hands playing with the lace of his lingerie, relishing the moans that escaped from Kageyama's mouth as Atsumu slipped in a third finger.

"Actually," Atsumu murmured under his breath. "I think it'll reach deeper if..."

With Kageyama still on Oikawa's dick, Atsumu spun him around to face him. As Kageyama gripped Oikawa's hands tightly, Atsumu pushed his length into Kageyama's hole.

Into Kageyama's hole, right alongside Oikawa's.

"So tight," Atsumu hissed, but he seemed satisfied as Kageyama's eyes glazed over, contentedly overwhelmed. "God, Tobio, your slutty ass can fit two dicks inside."

Kageyama bit his lip, slowly moving up and down, but fuck, the stretch was so much, it felt like every part of his body was being electrocuted. It didn't help that his neglected cock was caught between him and Atsumu, rubbing against both of each other's abdomens.

Oikawa tilted his chin over so that they were looking at each other.

"You okay, baby?"

"Y-Yes," Kageyama breathed. "F-Feels so good."

"Then ride us."

Kageyama nodded his head, leaning into Oikawa's open-mouth kiss as he bounced up and down. But then Atsumu was nipping his jaw, so he pulled away from Oikawa to kiss him as well, letting out a small squeak as Oikawa ran his fingers over his nipples.

"Hnmgh--" Kageyama swore he saw stars as Atsumu thrusted upwards. "F-Fuck--"

Oikawa and Atsumu's mouths moved all over Kageyama's neck, chest, and back, leaving bites wherever their tongues trailed. And slowly, they began to alternate thrusting up into Kageyama, deeply but oh, so slowly, enough to make Kageyama a whiny, babbling mess, incoherent pleas ringing through the air.

Oikawa was the first to cum, releasing hard into Kageyama, all three moaning at the warmth. He pulled out slowly, catching a trail of cum that spilled out with his fingertip, smearing it where Atsumu and Kageyama were connected.

"F-Fuck," Kageyama hissed.

Atsumu pushed Kageyama so that the latter was lying flat on his back now. Kneeling down, he hitched Kageyama's legs over his shoulder in a way that made his hip hover slightly over the bedsheets, and fuck, it made his cock reach so much deeper.

"Tell me," Atsumu began, punctuating the last word with a sharp snap of his hips, causing the other to cry out, "how much you love my cock."

Kageyama opened his mouth to speak, but as Atsumu suddenly gave him another deep thrust, cockhead pressing right against his prostate, only moans escaped.

It was enough for him to cum hard enough that his ears rang, cum splattering over Atsumu's chest and his own lingerie.

"I-I--" Kageyama's breath hitched as Atsumu thrusted into his prostate dead-on again, the overstimulation blurring his thoughts together. "S-So much--"

"Why? Is it too much for you, baby?" Atsumu teased, yet each snap of his hip suddenly became much more harder, much more quicker. Kageyama felt like he was going to go insane.

"Y-Yes," Kageyama stammered, squeezing his eyes shut as he felt Oikawa run his tongue over one of his nipples, a hand playing with his sensitive cock. "B-But, slut like me d-deserves it, d-deserves to be overw-whelmed, d-deserves to be p-pounded by your th-thick cock."

Atsumu's eyes seemed to gleam from the praise, and he leaned in to messily kiss Kageyama on the mouth.

"It really turns me on," Atsumu said when they parted, "seeing the King of the Court so submissive like this, all pliant like this, just because of me."

"I l-like being used by you, b-being fucked by you. Y-Your b-big cock fucks me s-so well," Kageyama told him, every part of his body trembling. "So th-thick, s-so big, stretches me out s... so well."

With one last thrust, Atsumu came into Kageyama with a loud groan. They lay there for a moment, Atsumu riding the last waves of his orgasm, before he slowly pulled out of the youngest.

"Did so well," Oikawa whispered, wiping the sweat away from Kageyama's forehead with the back of his hand. "Good boy, you did so well."

Kageyama was about to murmur a Thanks in reply, but he yelped as Atsumu spread his cheeks apart, sucking his sensitive rim where cum was leaking out.

"Good boy," Atsumu said, wiping his mouth to plant a kiss on the youngest's jaw. "You satisfied now?"

Incapable of forming a coherent thought, Kageyama merely raised his middle finger up at him, causing Oikawa to burst into a laugh.



"Kageyama-kun?" It was the voice of his teammate, Hinata. They were just beginning a practice match with Atsumu's team. "Are you okay? You're walking weird, and you're all covered in bruises."

"I don't think those are bruises," Tsukkishima muttered.

"I'm fine," Kageyama said flatly, though it was a complete lie--every part of his body was screaming, especially his ass.

Hinata pouted. "If you say so..."

Kageyama looked up just in time to make eye contact with Atsumu. Teasingly, the other setter pushed his tongue against the inside of his cheek to replicate the imagery of a blowjob, an all-too-embarrassing reminder of what had happened last night.

Mouthing a Fuck you, Kageyama readied his stance for the match, the whistle of the referee signaling the start of the game.
