Chapter Text
For years, Atsumu had harbored feelings for a certain man with a dark set of curls. Paired with even darker onyx eyes that glinted under the bright lights of the volleyball court, the man of his affections was unfairly handsome.
Cheekbones seemingly sculpted by the hands of God, lithe limbs born from hard work and effort, and alabaster skin littered with the prettiest of constellations (his favorite being the two moles framing the right side of his forehead; double stars), to Atsumu, Sakusa Kiyoomi was a galaxy. A mystery, a dream and above all…
Untouchable.
Atsumu recalled his first meeting with the alpha during a training camp. Standing across the court at the end of a grueling practice match with brows furrowed, the mild scent of bergamot and sandalwood seeped through scent blockers and sent Atsumu spiraling. While Sakusa had recoiled the moment he struck his hand out for a handshake, choosing to stare at him with piercing eyes that only sent a heat down his belly and sent his omegan pheromones spiking, the dark haired alpha had taken a sharp, greedy inhale.
Nodding at him briefly, dark curls bouncing to frame his handsome features, Sakusa had put on a mask immediately after shuffling off to a corner of the court to cool down.
Unreadable.
Atsumu recalled how he could not contain the sheer joy and excitement surging through his veins when he first caught the familiar scent of bergamot and sandalwood wafting through the air. Eyes shining at the sight of the alpha on the MSBY training courts, he was quick to holler and wave at Omi-kun, who had bulked up, grown taller and no longer slouched, standing to his full height.
Taking a few brief seconds to admire the alpha, Atsumu pranced over to welcome his teammate. He was eager to set to the dark haired alpha, pausing when Sakusa stared at him, gaze calculative and tentative, before emotions Atsumu could not quite put a name to, filled those dark onyx orbs.
Unfathomable.
Atsumu was in an unfathomable situation.
He couldn’t recall how he ended up in Sakusa’s living room, caged between the alpha and the couch. Soft lips pressing against his nape with a sense of urgency, leaving a trail of heat, Atsumu gripped onto the hem of Sakusa’s jacket, panting, the beginnings of slick running down the back of his thighs.
"Mine."
Atsumu had gone to practice as usual, bantering with his fellow teammates, Bokuto and Hinata. Laughing at a joke the former made, the omega had paid little to no attention to the arm of corded muscles slung over his shoulder, and weaved his fingers through soft orange tufts of hair instead, tousling it. Yelping when Meian joined them in on the fun banter and slapped his lower back, it was then Atsumu had felt it- a heated stare burning holes into his back.
“You guys are awfully close,” A low, husky voice sounded.
It stirred something in Atsumu’s belly.
Turning to meet Sakusa’s eyes, Atsumu had felt a spark run down his spine. It burned, seared and left a fire in its wake.
Was Sakusa upset? Angry? Jealous?
“Omi-”
“Miya, will you… come over to my place after practice? I want to… Speak to you,” Sakusa had spoken coolly, the fire in his eyes burning bright, betraying whatever calm he was holding on to, by a thin thread.
If that was how Atsumu's feet wound up entering Sakusa's den without so much of a doubt that he wouldn't leave the same way he entered, the omega lavished in how he was currently pinned under the alpha who lapped at this scent glands hungrily. Possessively. Like an alpha driven by pure instinct to mark what belonged to him.
Atsumu preened, purring at the attention from the alpha whom he'd been pining for, for years. A man with a dark set of curls, paired with even darker onyx eyes that left a fire in its wake, staring ever so intently, fondly and yearningly. An alpha he so desired to call his. An alpha he wanted to bear a bite; a mating bond on his nape for, for the rest of his life. An alpha by the name of Sakusa Kiyoomi.
"Omi-"
Every urgent press of lips on uncovered skin Sakusa could mark, left Atsumu whimpering in approval, bucking his hips to quell the fire and want, building inside him.
"Omi-” Atsumu murmured, latching onto Sakusa, who sucked onto his scent glands in reply, pulling the omega into his lap, "A- alpha."
A soft groan rumbled from Sakusa's throat.
"Mine."
A fresh pool of slick gathered under Atsumu at those words. Sakusa's nostrils flared, the grip on child-bearing hips tightening.
“Yours," Atsumu whispered, watching the alpha's pupils dilate, "Make me yours, alpha."
(And Sakusa Kiyoomi did.)
Turning up for practice three days later, Atsumu stood proudly beside Sakusa, who had an arm wrapped securely around his waist. Adorning a bite on the back of their napes- it was a mating bond that would bind them together for the rest of their lives. A claim on one another, as an alpha and an omega.
Forever yours, eternally mine.
