two dogs strive for a bone (the third runs away with it)

Summary:

“What is it, Omi-kun?”

He hates how the nickname Atsumu has given him rolls off Suna’s tongue. How he uses it to mock him.

Well. If this is the game he wants to play, then so be it.

“You know exactly what it is, Rin.”

Suna’s smirk falters for a second but, to his credit, he’s quick to put it back in its place.

“And what about it?” Suna says as he tries to push back against the firm hold Sakusa has on his jersey. All the other alpha is able to accomplish is to crane his neck further towards him, bringing their faces so close together that their noses touch. “Jealous much ?”

OR: the one where Alpha!Sakusa Kiyoomi and Alpha!Suna Rintarou want to court Omega!Miya Atsumu but they end up fucking each other instead. (Atsumu enjoys the show.)

Notes:

I always had a soft spot for SakuAtsuSuna and a while back I decided to explore the SakuSuna side a bit more...and this shameless smut is the result of my deeper dive into this ship!! It's tagged with SakuAtsuSuna, SakuAtsu, and AtsuSuna because of the 'bigger picture' I envisioned for this story, but this work specifically is mostly SakuSuna smut. If that's not what you were looking for, click away!!

Warning: overuse of the word 'alpha'. That being said, happy reading!

(See the end of the work for more notes.)

Work Text:

“What do you think you’re doing?”

 

Sakusa growls in Suna’s face as he pushes the other alpha against the lockers. The fact that Suna’s citrusy scent sweetens, as if happy by his outburst, only fuels his anger. 

 

It makes his pine scent turn smokey and bitter, like a forest set on fire. It’s so thick in the air that it clogs his lungs.

 

He hopes Suna chokes on it. 

 

Instead, he looks way too satisfied with himself, a smug smirk stretching his lips even as Kiyoomi grabs him by his jersey; holding the fabric in the tight grip of his fists. 

 

“What is it, Omi-kun ?” 

 

He hates how the nickname Atsumu has given him rolls off Suna’s tongue. How he uses it to mock him.

 

Well. If this is the game he wants to play, then so be it. 

 

“You know exactly what it is, Rin .” 

 

Suna’s smirk falters for a second but, to his credit, he’s quick to put it back in its place. 

 

“And what about it, Omi? ” Suna says as he tries to push back against the firm hold Sakusa has on his jersey. All the other alpha is able to accomplish is to crane his neck further towards him, bringing their faces so close together that their noses touch. “Jealous much?” 

 

“You know I’m trying to court Atsumu already, so back the fuck off.” 

 

“Oh?” Suna raises an eyebrow, the smirk on his face turning lopsided. “Careful, Omi-kun, that’s filthy language for a proper Alpha like you. Perhaps you should go wash your mouth.” 

 

Sakusa snarls at the patronizing jab. Something within him twists as Suna’s eyes roam over his face. Suddenly hyperaware of how close they’re standing, Kiyoomi makes to move out of reach, but before he’s able to, one of Suna’s hands reaches for his chin, grabbing him by the jaw and squishing his cheeks in the process. 

 

“Not to mention,” Suna shrugs, “since when two Alphas can’t court the same Omega?” 

 

Rage is making his blood simmer in his veins, because as much as it pains him to admit it, the other alpha is right. Sakusa knows he’s acting very immaturely, almost like a newly presented alpha, but seeing Suna scenting Atsumu in front of everyone– on the court no less– made him see red. 

 

It’s not uncommon for close friends or family members to lightly scent one another, sure, but while Atsumu might not be aware of Suna’s true feelings for him, Sakusa surely is– and Suna hadn’t meant that scenting to be platonic. 

 

He was so furious that most of his serves were out of bounds, all his receives were sloppy, and after the first set, coach Foster had to pull him out of the game. He just couldn’t stop replaying that image over and over in his head– the image of Suna thumbing circles over Atsumu’s neck scent gland. And Atsumu let him. 

 

“Scared he’ll choose me?” Suna’s smug voice drags him out of his thoughts and the mischievous grin that splits the other alpha’s face, added with his biting yet sweet citrusy scent, makes him snap.

 

Sakusa pulls Suna towards him just so he can push him again against the metal lockers, making Suna finally hiss and growl back at him. 

 

Sakusa doesn’t know why he does what he does next, but he knows that one second they’re growling at each other and the next they’re kissing– or, well, he kisses Suna. And Suna kisses back. 

 

It’s messy and aggressive– more teeth biting lips than anything else– and yet it still counts as a kiss.

 

One that lasts no more than a few seconds. Just as fast as it began, it ends. It’s Sakusa who pushes himself away from Suna, a low growl rumbling in his throat in warning. 

 

“What are you doing?!” He snaps. 

 

“What am I doing? What are you doing!” Suna looks at him bewildered. 

 

The thing is– he has no idea. What has gotten into him? 

 

“Why did you kiss back?” He hisses, because although he had clearly been the one who initiated it, Suna didn’t push him away. 

 

Suna scoffs.  “Why did you kiss me in the first place?” 

 

Sakusa doesn’t answer, because he doesn’t know

 

Neither speak for a tense second. They eye each other, trying to gather the other’s mood by scent and body language; both ready to leave and never speak of this ever again. 

 

That was the plan. Yet he finds himself crowding Suna against the lockers, again , as Suna loops his arms around his neck– and they’re kissing again.

 

The kiss is bruising, filled with a hunger he hadn’t known was there, and suddenly he craves more. 

 

Suna has his hands buried in his hair, gripping his curls tightly enough to make him growl. The sound is swallowed by Suna’s eager lips– they take, take, take without any hesitation, and even though that makes his alpha feel like he’s losing some kind of battle, there’s also a deep sense of satisfaction running through his body.

 

The few centimeters he has on Suna, and the fact that his shoulders are a bit broader, boost his alpha’s confidence– he’s engulfing the other alpha with his body against the lockers, hands on either side of Suna’s head, and the thought of making Suna feel small against him makes his scent flare up.

 

It’s just as potent as before, except that now it’s softer– almost sweet, instead of smokey.

It makes Suna groan into his mouth. For a split second, Sakusa thinks that it’s because Suna likes the way he smells, but he immediately suppresses the unexpected fickle of hope blooming in his chest. 

 

His scent gives away how much he’s enjoying this situation, and Suna most likely finds pleasure in knowing the effects he’s having on him. 

 

“Fuck,” Suna huffs, almost in an incredulous laugh, “assessing the competition, huh, Omi-kun?

 

“Shut up, Rin ,” he resumes their kiss, moving his hands to trace down Suna’s body– he stops at his chest, and Sakusa’s first instinct is to start playing with the other alpha’s hardened, pierced nipples.

 

He knew the alpha had piercings, had seen them before even, and yet he’s still surprised to feel the cold touch of metal seeping through Suna’s shirt. 

 

Suna’s hips snap forward, and Sakusa responds in tandem. Both of them are already half hard just from the smell of their pheromones permeating the air and their heated, unrelenting kissing.

 

He grabs Suna by the hip with one hand, the other still busy playing with a sensitive nub, and he starts to guide the motion of their bodies moving together, taking control of the pace.

 

It should be embarrassing, for both of them, how quickly it takes for their cocks to fill up– Sakusa finds comfort in the fact that, at least, neither of them will ever mention this to anyone else. 

 

A harsh pull on Suna’s nipple earns him a warning growl, to which he growls back with just as much fervor as their kiss.

 

He blatantly ignores the warning, pulling on that same nub once again, and what he gets in retaliation is a short pull on his curls– the kiss is broken and it leaves his neck exposed. 

 

His alpha doesn’t appreciate it. 

 

He hisses, but an unperturbed Suna leans forward. His swollen and spit-wet lips trace his neck– from his jaw down to where his scent gland is. For a moment, Sakusa freezes. 

 

He’s not used to people getting close to his glands, let alone someone who is also an alpha, and yet he relaxes quite instantly when Suna starts to suckle on it, a moan slipping past both of their mouths. 

 

The hand that was previously playing with Suna’s chest flies south, gripping Suna’s other hip to flush their groins together with more force.

 

“Eager, are you?” The chuckle Suna lets out against the damp skin of his gland sends shivers down his body. 

 

There’s a thrill rushing inside of him that makes his stomach twist in pleasure. 

 

“Let’s not waste any more time, yeah?” He breathes instead, groping Suna’s erection through the thin fabric of his volleyball shorts. 

 

Suna feels thick and hot even through his shorts. 

 

“You like that, Alpha? ” His voice sounds so smug, the appellative rolling off his tongue smoothly and with a low timbre that makes Sakusa's skin erupt in goosebumps. 

 

He bites the inside of his cheeks, hard, to stop himself from moaning unabashedly out loud.

 

Before Suna can throw at him a jab of any kind, he slips his hand inside of Suna’s shorts, past his boxers, and wraps his hand around Suna’s cock– it twitches at the very first stroke.

 

Suna throws his head back against the locker, cursing under his breath. In the silence of the room, the otherwise quiet hiss couldn’t be missed, and Sakusa takes this moment as his opportunity to taunt Suna. 

 

“Does it feel good,” He purrs, and then, unable to stop himself. “Alpha?” 

 

Sakusa parrots Suna’s tease, which makes Suna inhale sharply and bite his bottom lip. It’s still not enough to stop a whimper– a whimper– to slip past his lips. 

 

How cute, Sakusa thinks to himself. Just a few tugs at his cock had Suna whimpering.

 

Sakusa feels victorious, his alpha is pleased, and his cock throbs in its confinement. 

 

Perhaps there has been a shift in his scent because soon Suna is reaching out to touch him through his own shorts.

 

Suna expertly handles him with swift movements, and it feels great even through his pants– perhaps Suna wanted to take his alpha down a peg with his deft movements, because the smirk that starts to bloom on his face urges Kiyoomi to shut him up with his mouth before the other alpha can utter something that he knows he won’t like to hear.

 

With renewed fervor, they eat at each other’s mouths; their hands working up and down their shafts like it’s a competition on who brings the other to orgasm faster– but Kiyoomi can’t have this moment ending too fast. For reasons to him unknown, he wants to savor this moment slowly. 

 

He breaks the kiss– they’re breathing heavily against each other’s mouths, lips shiny with spit; red and plump from their aggressive kissing as Kiyoomi swats Suna’s hand away from his cock so that he can take the both of them in his hand.

 

They’re roughly the same size, which makes it difficult to wrap his hand around them both. 

 

Thank god he has big hands.

 

He starts to tug both of their cocks at the same time, and he looks Suna straight into his eyes as he does so. He needs to savor the blissful expression on Suna’s face; the way his cheeks are flushing red and the way his chest heaves with heavy breaths.

 

Sakusa drops his gaze lower, down to where he’s stroking their cocks snugly together, and the view makes him croon deep in the back of his throat. 

 

Suna moans, lewdly and openly this time, after Sakusa twists his upward stroke just right, giving attention to the tip of Suna’s cock with his other hand. 

 

Then, because Suna’s shirt is ruining the view, he takes hold of it and brings the hem up to Suna’s mouth. 

 

“Hold this,” He says, and despite the fact that he sees the same gleam of arousal reflected in Suna’s eyes, the other alpha doesn’t comply with his request.

 

He leans in; his lips close to the shell of Suna’s ear. “Be good for me, Alpha.” 

 

At this point, he’s not even sure if he means to use the appellative to taunt Suna or just to arouse him further– what he knows is that Suna’s breath breaks, as if it has been punched out of his lungs, and his hands hold on tighter on Kiyoomi’s shoulders.

 

“Besides, we don’t want anyone to hear us, do we?” He purrs, just before nipping at the skin between Suna’s ear and jaw while his hand works them painfully slow.

 

Sakusa can feel the fight going on between Suna and his instincts– the other alpha’s body is tense against his, scent turning a bit too bitter, but in the end, Suna complies with his instruction. 

 

Suna bites onto his shirt, revealing his smooth, toned stomach. 

 

Talk about killing two birds with one stone. Besides muffling Suna’s moans, this also gives him a good view. 

 

As Kiyoomi drops his forehead to rest on Suna’s shoulder, he can’t get his eyes off of the light dust of sweat that makes the skin of Suna’s toned stomach glow under the artificial lights of the locker room; gaze following the happy trail of hair down to his pelvis. 

 

He growls through his teeth, but this time there is no threat behind his rumbling, but rather a strong urge to bite– he can feel his teeth ache with the need to sink into supple flesh.

 

Sensing his need, Suna growls back. 

 

“What?” Suna taunts him as he removes the hem of his shirt from his mouth and holds it with his hand. “A strong-willed alpha like you needs to be muzzled?”  

 

Kiyoomi has always prided himself on having great self-control over his instincts– he never had to be restrained, let alone muzzled. 

 

Not even during his ruts, and even though today is proving that perhaps his will is not as strong as he thought it was, Suna’s words would be more effective if not for the way he is gripping onto his shoulder for dear life as Kiyoomi works them toward their peak. 

 

Despite the jab not landing the way Suna hoped for, the urge is still there. 

 

Before he regrets doing something too stupid, he stuffs Suna’s mouth with his shirt again and starts to nip Suna’s skin– it’s not quite what he craves, but his ache settles as any sliver of Suna’s exposed skin gets painted in shades of reds, blues, and purples. 

 

Then he lets his mouth wander lower– down from Suna’s collarbone to his chest; until he finally closes his lips around his hardened nub while his free hand moves up Suna’s torso to cup one of his pecs; thumb playing with his pierced nipple.

  

He alternates kitten licks with lightly suckling at the piercing in his mouth, only stopping when Suna starts to squirm against him to bite on the meaty part of Suna’s chest instead, making him hiss and thrust his hips forward– they’re both leaking and with the aid of their mixed precum, Suna’s cock slides against his in his grip. 

 

“Or perhaps I could put a collar around your neck.” He purrs, “ just like an omega in heat.”  

 

A smirk stretches his lips as he feels Suna’s cock throb– hard – in his hand as he speeds up his strokes. 

 

“Would you like that?” 

 

Suna whimpers, drool wetting the shirt between his teeth, as his hips snap the best that they can in order to fuck into Sakusa’s hand. 

 

“Nu-uh,” Sakusa mumbles in disappointment as the hand previously busy with Suna’s chest goes to grip Suna’s hip to keep him still. “You’ll take what I give you.” 

 

Suna takes a loud intake of breath, scent spiking at his words, and his smirk grows even more prominent when he can feel Suna’s knot start to inflate in his hand, against his own cock.. 

 

“Really, Rin ?” He chuckles, feeling incredibly smug. “You’re really about to pop a knot?” 


“Shut up,” Suna growls in response, but the way his cock twitches speaks a whole other truth, and when Kiyoomi finally drags his gaze away from their lower bodies, his breath hitches. 

 

Suna’s eyes are moist, some tears left unshed while others have smudged his eyeliner, leaving black tear streaks down his cheeks.

 

The heat in his lower stomach sinks even lower in his groin. 

 

Suna is keeping his chin close to his sternum, refusing to bare his neck to him again– as if now that Sakusa has seen him this vulnerable due to his ministrations, he can’t bear another sign of submission in front of him. 

 

Sakusa grabs him by the hair, pulling on them till the other alpha has his head thrown back against the lockers. Suna’s growl comes out more like a whimper, and when Sakusa nuzzles his scent gland, latching his mouth to it, the knot in his hand grows bigger.

 

Kiyoomi suckles on the bulging gland, and the fresh, pungent citrusy scent of Suna hits him harder than ever before– he smells good, and tastes even better. 

 

Suna moans brokenly– that’s when he lets go of his own cock to focus solely on Suna’s.

 

Instead of picking up the pace of his strokes, he tightens his grip at the base of his cock, just above Suna’s knot, his other hand still firmly gripping Suna’s hair. 

 

Suna grunts in frustration, sicking his nails into his back in retaliation for cutting off his orgasm. Instinctively, Suna writhes in his hold, and so he crowds his body closer to Suna’s, putting more of his weight against the other’s body to keep him still.

 

Suna’s chest rises to the rhythm of his short, quick breaths.

 

He craves to touch his own cock again, to bring himself to orgasm, but he needs to see the other alpha come undone before he can do that.

 

“Mmhh , ” he hums against Suna’s glands in a low rumble that makes Suna’s skin rise with goosebumps. A bead of precum reaches his fist around Suna’s cock. “What’s the magic word?” 

 

Fucker. ” Suna hisses. 

 

Of course this is when Suna decides to be difficult.

 

“No, try again, sugar.” 

 

To be honest, he doesn’t even know where that pet name came from– it slipped against his better judgment.

 

It was probably Suna’s scent’s fault. The sweet undertones of it went to his head, that’s why it slipped past his lips.

 

Although it wasn’t his intention to say it, it worked wonders on the other alpha. 

 

“Please.” Suna rushedly says.

 

When Kiyoomi raises his head from the crook of Suna’s neck to look into his eyes, he can tell that the other alpha didn’t mean to plead– not this eagerly, at least.

 

Kiyoomi frees Suna’s hair from his grip and lowers it to wrap it tightly around Suna’s knot– it’s the easiest way to trick an alpha’s biology into thinking they have something to latch their knot into. Suna gasps, and Kiyoomi resumes stroking his hardness with his other hand.

 

With both of his hands on him, Suna quickly falls apart– every breath turns into a breathy moan, eyes unfocused somewhere down his body where Sakusa’s hands are working him up to his peak, and cheeks stained black with ruined makeup.

 

Like many other times this evening, Sakusa does something that he shouldn’t and kisses Suna. Sure, they had kissed earlier. But it was out of anger, whereas now it feels different– if only slightly. Suna responds to his touch immediately, hands sinking into his curls. The moment he tightens his hand around Suna’s fully expanded knot, coupled with an upright stroke with just the right twist of his wrist to his cock, Suna comes.

 

His moans die in Kiyoomi’s mouth, who swallows each and every one of them eagerly.  

 

As Suna comes down from his climax, they rest their foreheads together to breathe. Suna sounds like he has just played another volleyball match right now, but by his scent, Kiyoomi can tell that he’s satisfied– happy even. 

 

It’s in this calm that it hits Kiyoomi’s senses. A third scent– one that he recognizes.

 

One that smells of lavender and cedarwood. 

 

He doesn’t leave Suna’s side; his instincts telling him to stay close to Suna as he’s vulnerable in his post-orgasm haze, but Kiyoomi turns to look toward the source of the scent. 

 

Sure enough, there he stands by the half-open door. His eyes are wide.

 

Sakusa doesn’t know what the omega he wants to court is thinking, but it doesn’t take long for Kiyoomi to see the slick running down his thick thighs, soaking through his shorts. 

 

Kiyoomi doesn’t feel as panicked as he probably should, but his eyes are probably wide from being caught doing this with Suna of all people, and he’s about to ask Atsumu how long he has been standing there. 

 

Except that he doesn’t get the chance to. A hollow thud resonates into the silent room, and a hand closes around his cock. 

 

He should be more concerned about Atsumu standing by the door, but Suna is kneeling before him with mirth swimming in his eyes– which is never a good sign.

 

He wonders if Suna is aware of Atsumu standing just a few meters behind them. Sakusa supposes that he must be, because it’s not like Atsumu is trying to hide, and his sweet, sweet scent fills the room and– thoughts leave his mind when the other alpha decides to prove his point.

 

Instead of taking him into his mouth, he nuzzles his erection. 

 

His hands fly to grip Suna’s hair on instinct, but Suna stops him by gripping his wrists.

 

Looking up at him, Suna leaves a trail of wet kisses on his cock until he reaches the tip. Sakusa’s breath gets stuck in his throat when Suna closes his lips around the tip of his cock and starts to suckle on it– once, twice, and then– nothing. 

 

Suna just resumes leaving lewd kisses down the same path he came from on his shaft. 

 

He snaps, growling low to incite Suna to actually put his mouth to work, but it only makes Suna smirk harder against his cock. 

 

“Mmhh,” Suna murmurs as he looks up at him, “what’s the magic word?” 

 

Sakusa scoffs. Of course he’s throwing his words back to his face. He doesn’t want to play along, but he’s close, feeling drunk on Suna and Atsumu’s scents mixed with his, and that is enough to make him comply. 

 

“Please.” He makes sure that his voice remains firm.

 

Suna does look a bit surprised, if not even a bit disappointed that he played along right away, but he’s done his part, and Suna now follows through with his. 

 

Without breaking eye contact, he licks a long stipe at his cock.

 

The sight before his eyes is sinful, with his cheeks still stained in black tear streaks and lips red and puffy. He thinks he can hear Atsumu muffling a whimper behind him.

Suna closes his lips around him, and it brings Sakusa real joy to see Suna letting go of one of his wrists to wrap his hand around what doesn’t fit in of his cock. 

 

He hollows his cheeks as he moves up his cock, and that makes him moan loudly.

 

He can feel his climax nearing already. He feels only slightly embarrassed for being so close to orgasm already– but he has been riled up for hours now, and Kiyoomi can feel his head swim because of the alluring scents permeating the room, so it’s not like anyone could blame him for coming too fast. 

 

Suna works him expertly with his mouth, but the moment he laces his now free hand in Suna’s hair, the other alpha unlatches his mouth from him. Again.

 

He groans in frustration, hips snapping forward in desperate need to be engulfed in the warm heat of Suna’s mouth even as Suna’s hand starts stroking him.

 

He’s so close, and despite his best efforts, his knot starts to form at the base of his cock. 

 

Suna raises an eyebrow. 

 

“Really, Omi?” Suna parrots. “You’re really about to pop a knot?” 

 

God, he’s insufferable. 

 

Although he mockingly throws his taunt back at his face, Suna’s hand doesn’t stop working his cock– actually, he brings his other hand around his growing knot, just like Kiyoomi had done earlier for him.

 

The grip around his knot sends zips of pleasure through his body, but nothing could have prepared him for the sight of Suna Rintarou opening his mouth wide open, tongue out in front of the tip of his cock.

 

It only takes one more tug and a firm, continuous squeeze to his knot for him to come.

 

He sees white, vision swimming for a second, and he has to lean over Suna to land a hand on a locker in order not to fall on his ass.

 

His breath leaves his lungs in short puffs of air, mouth open in a silent moan, and when he comes down from his orgasm just enough to open his eyes, he has to close them again– Suna’s face is painted white with his come, and he thinks he could come again just from the feeling of Suna’s lips closing around his tip as he suckles him dry.

 

He curses under his breath, and a long string of fuck is the only word he can think of until Suna lets go of him. 

 

Sakusa looks down at Suna, and Suna looks up at him. They stay quiet for a handful of seconds before Suna tears his gaze away from him to look past his frame– eyes zooming onto their accidental spectator. 

 

“Did you like the show, Tsumu?” Suna says as he eyes hungrily the omega.

 

Kiyoomi turns, and a fresh wave of hunger washes over him. There’s a wet patch just on the front of Atsumu’s shorts. 

 

Sakusa watches Suna stand up, eyes never leaving Atsumu, even as he leans his body against Kiyoomi’s as he says. “Come here, Tsumu, we’ll take care of you.” 

Notes:

I think we can all agree that Atsumu is the winner here, which makes him the dog that runs away with the bone, eheh :3
