Day 02: “Do it. I dare you” (nsfw | a/b/o | Bitching) 

Tension lingers on the court whenever Sakusa and Atsumu exchange less than subtle glances at one another. Shoulders brushing as they stand side by side in the locker room post-practice,

the flare in pheromones wafting through the air is instant, and overpowering. 

A friction between two alphas that goes beyond petty competitiveness they have had since high school, there has been a noticeable shift in their relationship,

ever since a drinking session with the MSBY team left them tumbling into a love hotel, fighting for dominance, and exchanging touches far from gentle. 

Purplish bruises blooming across tan and otherwise unblemished skin, bloody scratches raking down a pale,

broad back scattered with constellations of moles- a one night stand becomes two, followed closely by a third that takes place in the locker room.

Before Sakusa and Atsumu know it, it becomes a weekly routine for them.

It’s not a common arrangement between two alphas, but it’s certainly not unwelcome.

Not when the sexual compatibility they have makes it a gratifying way to let off steam, rid themselves of pent-up emotions that have only gotten increasingly complicated over the months,

and work out their aggression, after sending snark in each other’s way during practice, riling one another up at every given opportunity they have. 

Friendly rivalry, rough fucking and budding emotions they attempt to turn a blind eye to,

Sakusa and Atsumu convince themselves that what they have ongoing works for them. 

That is until Atsumu decides to fuck things up and address something that has been weighing heavily on his mind.

“Omi, why’re yer so afraid of leaving marks on my nape? ‘s not like I’m.. Y'know, an omega.” 

Atsumu hesitates, voice trailing off in uncertainty.

There’s an uneasiness building in his belly, and he’s beginning to think he shouldn’t have even bothered asking.

The silence that greets him only makes Atsumu more anxious with each passing second. 

All too suddenly, the cum pooling between his inner thighs and seeping out of his rim feels cold.

Discomfort lingers on every inch of his bare skin.

Where did the warmth and heat that he just shared with Sakusa go?

To be fair, there isn’t a need to put a label to the relationship they have. (Or lack thereof.)

There is no need to raise any questions as to why the taller alpha of the two always marks every part of his body,

except for the back of his nape.

Leaving it free of marks, a part of Atsumu feels hollow, as he traces the hickeys Sakusa has left on the rest of his body. 

Heart twinging in his chest, he can’t help but muse: 'What if Omi marked my nape and bit down on my scent glands?'

It’s strange having such feelings as an alpha, but he’s been experiencing these brooding thoughts recently.

With the distance between Sakusa and himself closing, it’s getting harder to meet the taller alpha’s smothering gaze that locks in on him during practice.

Oblivious to the hungry pair of eyes that fixate on where he rubs the back of his nape self consciously, Atsumu only realises Sakusa’s hyperfixation on him, when the domineering scent of sandalwood and arousal spikes in the room.

Going painfully still at the hardness pressing against the small of his back, the blonde alpha quivers at the heat radiating from large, calloused palms coming to rest on his hips. 

“Do you want me to?” 

Petal soft lips brush against the back of his nape.

“To mark, bite and claim you?”

Atsumu gasps, a shiver rolling down his spine.

Trembling when the barest hints of incisors scrape across his scent glands by his nape, he isn't sure what comes over him or what triggers something in him to snap,

but Atsumu whips his head and weaves his fingers through soft, dark curls, tugging Sakusa towards him into a rough, bruising kiss.

Pulling away with a smirk, he licks his lips and shivers in anticipation at the desire pooling in the taller alpha’s eyes.

The grip on his hips tightens.

"What would ya do if I said yes? Are ya scared, Omi? Afraid? Too much of a coward?

Ya bite's never gonna catch, if yer don't even have the guts to try. Big talk coming from an alpha who wanted to bitch me from the get go."

A low growl of threat emits from the back of Sakusa's throat at being openly challenged. 

Atsumu sneers, a fire igniting in the pits of his belly at the sight of those teeth he wants buried into his nape and scent glands, glinting.

He knows he's pushing it- the boundaries of the relationship they have, but it doesn’t stop him. 

It's thrilling to see those onyx eyes darkening, pupils blown wide in lust. 

"𝘋𝘰 𝘪𝘵. 𝘐 𝘥𝘢𝘳𝘦 𝘺𝘢."

The last string that has been keeping them from crossing the line and tiptoeing around one another snaps. 

“I’m going to fucking ruin you.” is the last warning Atsumu gets. 

//End...?

Lips parting into a silent scream from the sharp pain of teeth sinking in just shy of his scent glands, claiming him the way an alpha and omega pair would, Atsumu sobs, scrambling for some form of purchase on rumpled sheets.

If this is how it feels to be bitten, what happens if Sakusa really bites into his scent glands and ‘claims’ him? 

The rational part of Atsumu knows that it’s unlikely an alpha like himself will ever get bitched, but he can’t quite help getting his hopes up.

Writhing as Sakusa leans in to fist his dribbling cock, all the while mouthing and gnawing at his scent glands, Atsumu thinks his vision flashes white, the moment the taller alpha guides his hips and impales him onto his cock.

“Fuck… Just look at how well you’re taking me in,” Sakusa groans, revelling in the way Atsumu clenches down, chest heaving. 

Slick, hot, tight- made just for him.

Atsumu doesn't usually feel so soft, pliant and slick. Neither does he naturally smell so tantalising, like fresh peaches harvested from the finest trees.

Saccharine sweet, Sakusa takes in greedy lungfuls of air, jaws aching, saliva pooling at the back of his throat.

Something has obviously changed and shifted in their relationship, but neither of them realise it, caught in the pleasure of being pressed against one another and connected like two interlocking pieces of a jigsaw puzzle.

"O-omi-"

The whine that trails off into an uncharacteristic whimper sends Sakusa growling, snarling and pistoning his hips to chase after the all encompassing heat that he wants to carve a space for himself in.

His knot is beginning to fill, but the way Atsumu's hole clenches down greedily has Sakusa thinking that maybe, just this once, Atsumu can take his knot without him pulling out, only to fuck his cum back into him just to get the satisfaction of marking him, someway or another.

Something about filling the setter up, tainting him from the inside, and subduing him, has the alpha's pheromones thickening, permeating the air in smothering waves.

"Atsumu," Sakusa groans lowly, burrowing his face into the curve of Atsumu's shoulder.

The palm that has been resting on the latter's toned torso travels down to his lower abdomen, where Sakusa can almost feel how deeply his cock reaches the blonde alpha. 

It drives Sakusa wild, an animalistic side to himself encouraging him to press down on Atsumu's belly.

Applying pressure, Atsumu chokes on a broken sob and squirms on his cock, babbling incoherently.

Reaching out to grip his hand as a way to anchor himself, the setter rocks his hips back in tandem to meet every roll of powerful hips driving into his core.

"P-please, Omi. I.. I need it," Atsumu begs, tears streaming down his cheeks in rivulets.

Craning his neck in an awkward manner to exchange a wet bruising kiss that feels way too intimate,

everything seems to fall into place when Sakusa knots him in place with a feral snarl, spurting hot streams of cum into his plaint body as he sinks his teeth into Atsumu's scent glands by his nape.

Atsumu screams, thrashing in the taller alpha's firm, possessive hold.

In the heat of a moment, coming down from their climaxes, some semblance of clarity and realisation seem to pass between them, at the fresh gloop of wetness leaking out of Atsumu's puffy rim that continues to milk Sakusa's knot. 

It's not cum.

An eerie silence blankets the room. 

"D-did ya actually bitch me?" Atsumu rasps, thighs trembling to hold him up, an ache building in his belly, "Fuck."

Sakusa blinks and casts his gaze down where they're still knotted in place.

"... We just did."

"Ya idiot! That's not what I'm- nghhh," Atsumu mewls weakly, feeling another steady spurt of cum paint his insides. 

He may be looking like he's all fine and dandy on the outside, but his thoughts are a train wreck, going at a thousand miles per second.

Sakusa has the cheek to huff in amusement, cracking a rare, tiny smile that leaves the setter gobsmacked and a burst of heat surging through his body. 

His scent sweetens instinctively, and Atsumu catches the immediate interest pooling in the alpha's wanting eyes.

"Are you implying that wasn't enough for you, Atsumu?" Sakusa murmurs hotly, manoeuvring them such that they are facing one another. 

Atsumu flushes a scarlet hue.

They both know that they need to talk, and address the emotions they have been sweeping under the carpet,

but for now, as slick gathers under the back of Atsumu's thighs and the scent of heat spreads across the air, Sakusa knows he has a job to do. 

To please his omega, and his mate, Miya Atsumu.
