Work Text:
Within the Teiko Empire lies Seirin; the empire’s smallest and only hamlet. With not even fifty people to its population, it is incredibly easy for news and gossip to spread among the inhabitants. There are no secrets within, the people honest with nowhere to hide behind lies and deceit.
Some of the nearby villages, namely Kaijo as its closest neighbour, insist that those from Seirin join them under one village, going as far back to the founding of the empire. Yet Seirin holds strong, determined to remain its own community despite the dwindling population.
Leading the hamlet is its lording family, the Aidas. Kagetora currently takes on the role of Head Alpha. His second mate is Shun, an omega 21 years his junior. Kageotra’s heir is his only pup from his first mate, his daughter and an alpha herself, Riko. She’s mated to beta Junpei.
Shun was 13 when he presented as an omega, the first of his friends to present at all, one being Riko who is not even a full two seasons his junior.
When spring returned with pink blossoms caressing the air around him, Shun participated in his first (and only) Annual Mating Run.
As the only omega of Seirin and the mate of the head, Shun found himself under sudden responsibility and immense pressure.
Within a year, Shun gave birth to Kagetora’s second and youngest pup, Kouki.
Much like his elder half-sister, Kouki takes after his father with brown and fluffy hair, the same shade of brown for eyes as Riko, unlike Kagetora’s own dark eyes.
Shun doesn’t see much of himself in Kouki, but he loves him all the same.
Kouki, much like his mother, presents as an omega. It comes as a great surprise to Seirin; omegas, especially male omegas being as rare as they are.
It’s a couple weeks after his 14th birthday when Kouki experiences his transformation heat. It’s long and painful as his body changes to accommodate the ability to give birth, and Kouki is left utterly exhausted by the end of it.
When the unbearable heat begins to wane, his mother comes to his room, dark eyes concerned as he brushes Kouki’s cheek with his knuckles.
“Kouki, my sweet pup,” Shun murmurs as Kouki, even within deep slumber, nuzzles against his mother’s loving touch. “I hope you are not Claimed as quick as I was.”
“What’s it like?”
“What’s what like, Taiga?” Kouki asks in return.
Taiga and his parents, the most recent additions to Seirin, are from overseas. Hailing from Jabberwockian territory, Taiga has an alphan Jabberwockian mother but a Teikonese and alphan father. Kouki has no idea what brought the family to their small community as opposed to the larger villages within the empire.
Taiga pouts, his right cheek growing as he watches Kouki continue his task.
“What’s being an omega like?”
Kouki looks off into the distance, pondering the answer to Taiga’s question.
“I…don’t know,” Kouki answers honestly. “I don’t feel any different.”
Taiga looks at him, not quite believing, but not doubting his friend either.
“I mean—yes, things are definitely different now, and new things are expected of me but…” he trails off, not sure of the words leaving his mouth.
“...maybe you just need more time to process everything?” Taiga offers.
“...maybe…” Kouki agrees.
It’s Kouki’s first time at the Mating Run Site, well, the first time he remembers that is.
It takes days of travel to reach Rakuzan, the capital of Teiko. They only stopped to sleep and relieve themselves; eating was mainly done on the move with the dried and preserved goods that Shun prepared in advance.
Every unmated alpha and omega is required to participate in the Mating Run, whether they presented a week ago or are old and graying. Widowed alphas and omegas also have to participate if they are without pups, but have the choice to participate if they want a second mate if they do have pups. Betas, on the other hand, have the option to participate once they’re 16 years, if they so wish. Such an instance happened during Kouki’s first visit as a toddler with Riko and Junpei.
On top of alphas and omegas being required to attend, all immediate family members of a participant are required to travel with them. Something made mandatory to show support to the unmated members of their family.
The location for the Annual Mating Run is on the outskirts of Rakuzan, on land technically owned by the Emperor. It’s a large forest, almost as large in land mass as the capital itself. The forest is also dense, according to his family. It’s filled to the brim with many trees, flowers and animals alike. Not to mention the unfamiliar species of bamboo that lines the perimeter.
Kouki swallows around nothing as he stares into the unending foliage in an attempt at comforting himself; he can only begin to imagine how easy it is to get lost in there…
“Kouki?” His mother calls, as if sensing his pup’s worrying. Kouki turns to look at him, concern evidently etched into his features. “The forest isn’t as bad as it looks, you don’t need to worry so much.”
Kouki glances back towards the forest, then over to the rest of his family where they’re putting together their little home away from home for the next couple days or so. Kagetora and Riko are putting together their shelter, all while Kagetora is yelling at Junpei about their food supply or something.
“Kouki,” his mother says, demanding his attention back.
“If you’re that worried,” he starts when Kouki meets his eyes once more, “there are plenty of hiding places. Most alphas won’t be able to find you if you remember to control your scent like we practiced.”
“Won’t it be difficult with the heat inducer though?”
Heat inducers, some concoction prepared specifically for the Annual Mating Runs (and made with ingredients Kouki can’t even begin guessing), bring on a temporary heat for omegas. Alphas have a rut inducer as well, which makes the run sound all the more scary. Kouki can scarcely imagine what a true rut is supposed to be like.
“That is why we practiced while your heat was dwindling.”
Kouki forgot about that, his first ever heat feels like forever ago now despite it barely being a full season. “…oh.”
His mother gives him a reassuring smile, and brings him into a tight hug, his scent turning soothing as toasted nuts and something else slightly smoky and earthy envelops Kouki.
It’s waiting time now, the Run not starting for another day as more alphas, omegas, the odd beta and their family arrive from all over the empire.
Kouki sits between both of his parents as a sort of display or ‘sneak peak’ for passing alphas or betas who might be interested in claiming him this Run. Riko, as an already spoken for alpha and close family member, sits a little behind and to the side of their father, with Junpei as her mate on her other side.
“I just realized something,” Riko says suddenly. All members of the Aida family turn to look at her. “Didn’t the Emperor join the Mating Runs the same year as you, Junpei?”
Junpei blinks at her. “Ah, I believe so, yes. Back when he was Crown Prince?”
“It’s been how long again?
“Eleven years now? That’s how long you and I have been mates.” Junpei answers.
Riko whistles. “Hard to believe that no one has jumped at the opportunity to be mates with the Emperor after all this time.”
“I’m sure there has been,” Kagetora jumps into the conversation. “I imagine His Majesty hasn’t found any of their scents appealing. You know how sensitive your nose gets during ruts, Riko.” He gives his daughter a pointed look.
Riko at least looks a little sheepish, a rosy hue covering her cheeks as she rubs the back of her neck.
“…have you heard anything about his council or the higher nobility getting worried about his lack of mate and heir?”
Kagetora, who normally douses both of his pups in unbridled love and affection, sends his daughter a warning glare.
“Riko,” his tone has an almost growl to it. “We are not to speak of His Majesty this way, especially at the Annual Mating Run when he and his knights could be anywhere. Restrain yourself.”
“Yes, of course. Sorry Father.” Riko apologizes, head bowed.
Kagetora’s glare softens somewhat. “You better hope no one else heard, or I won’t be the only person you’re apologizing to.”
Kouki’s standing at the edge of the forest, right next to the bamboo, with about one hundred other omegas consisting mostly of young women similar to him in age. There is also the odd beta, all women, looking to potentially mate with an alpha or fellow beta.
A breeze filters through from the forest, hitting Kouki’s little bit of exposed skin. It feels nice, and relaxes him somewhat.
He’s dressed in the most extravagant kimono his parents could afford. It’s furisode, and mainly white, signaling his ‘bridal’ status. It’s plain for the most part, with red, orange and gold stripes on the bottom, reminiscing a sunset, and trails behind him in its deepest and most vibrant shades. The obi is tied comfortably snug.
Kouki can confidently say he’s never worn anything as decadent as this, more used to the light and informal styles that fit the lifestyle of those in Seirin.
It’s overwhelming, making his omega status suddenly feel much more real. His grip on the cup tightens, the heat inducer inside sloshing around and threatening to spill over onto the earth below. He forces himself to relax, the inducer smelling oddly sweet as it wafts up to his nose.
A ring sounds throughout the clearing, indicating to the waiting omegas that it’s time to drink the inducer.
Kouki, not giving himself the opportunity to talk himself out of it, immediately raises the glass to his lips. He ignores the too sweet scent, how it causes his nose to scrunch in displeasure and tips the glass, the liquid inside sliding down to his waiting throat.
The inducer is unexpectedly thick and slimy, making it difficult to swallow. It burns its way down his throat, settling warmly into his stomach.
It’s so gross…
If it wasn’t for the inducer, Kouki wouldn’t mind coming back every year until he felt ready to mate.
“Remember, Kouki; the key to an invisible scent is neutrality. There isn’t much you can do about your slick, but if you keep control of your emotions and don’t panic, your slick will more likely than not be chalked up to something floral to most alphas.”
Kouki plays his mother’s words on repeat, bare feet repeatedly hitting the dirt of the forest floor as he runs.
He stumbles over logs and tiny stones sticking up from the ground and faint paths, unused to the terrain of the Annual Mating Run forest.
He steers clear of the others, not wanting to be too close to anyone who is actually looking to mate this season or just anyone, really.
Heading further into the forest, Kouki ignores the slick trailing down his thighs and the tantalizing trail he’s leaving behind. He ignores the pain in his feet and chest, ignores how he’s pushing himself past his limits and how he can’t fucking breathe, fuck, fuck, fuck!
He stops, inhaling gulps of air as he drops to his knees, hands fisting into the dirt, desperate to breathe.
Faintly, Kouki catches the same thundering beat and following horn that had released him and the other omegas into the forest; except it’s the alphas’ turn this time.
Finally catching his breath, Kouki wipes his mouth with his sleeve of the spittle from his dry heaving, not caring if he ruins the kimono he wears more than he already has. Seriously, whose bright idea was it to dress in their best kimonos for the Mating Runs?
As the announcement ends, Kouki listens to the sounds around him as best he can. He strains himself, holds his breath for just a moment, in an attempt to hear anything.
Water. He realizes with excitement. There’s flowing water nearby.
“If you happen to come across water, a river or something, go in it. It’ll help wipe clear your scent. Kouki, the most important thing; don’t take your kimono off. You don’t want your scent sticking to an unattended kimono, they’ll know you’re nearby and the last thing you want is to be caught by an alpha while nude.”
Feeling determined once more, Kouki swallows, digging his nails into the dirt as he staggers to his feet.
He’s wobbly, legs unused to running nearly as much as what he just did.
It doesn’t take long to reach the source. It’s beautiful; in a small clearing runs a river, the clearing providing space for the river to widen. There’s large stones at the shore, what Kouki imagines to be a lovely sunbathing spot, unblocked by the leaves of the trees above.
Kouki makes his way into the water, heading to the deepest and most centered part of the river. He can’t help but smile in awe, ignoring the chill that his body is subjected to as it enters the water.
“Mother said my whole body needs to be submerged for the best results…” Kouki whispers to himself, watching the ripples in the surface of the water as he moves his arms.
He takes a deep breath and ducks, water rushing to surround him completely.
It feels so nice, Kouki thinks as the water cools the rest of his heated skin. It clogs his ears, muffling the sound of everything outside yet enhancing everything within. If it wasn’t for the risk of drowning, Kouki could imagine himself just like this forever; body cooled and floating in a sense, being gently carried forward by the current as everything else dulls around him. Life would be perfect…so peaceful.
…you’re in the middle of a Mating Run, Kouki’s mind reminds him rather unhelpfully, you’re in a temporary heat with rutting alphas running wild. You can’t afford to rest. Don’t forget you have your family and everyone back in Seirin waiting for you to come home.
Kouki gasps as he breaks through the surface of the river, tilting his head back to avoid getting water from his dripping bangs into his eyes. Air greets his lungs like an old friend.
Sunlight sneaks through the leaves above, warming his face briefly before the breeze he once thought pleasant bites his wet skin.
As he makes his way to shore, Kouki collects the loose fabric of the kimono away from his skin and wrings it out, not wanting the added weight to hold him back. He won’t be able to get all the water out, but he can at least try when it comes to the trail and dangling sleeves.
He can’t help but continually shift his gaze, not wanting to be caught off guard by any nearby alpha able to control their scent.
When the river is up to his mid-calf, Kouki catches something flash between the trees. He squints his eyes in the direction it came from, trying to get another glimpse. It looked…red? Way too vibrant to be something from the forest…perhaps someone’s kimono? No, it was way too high up and small to be—
Kouki’s foot slips on a loose, moss-covered stone. He panics, his balance lost, and flings his arms out, looking for something to hold on to to prevent falling back but there’s nothing and—
“Careful now,” a smooth and deep voice says suddenly, a warm breath practically kissing Kouki’s ear. A firm yet gentle hand grabs one of his flailing arms, the other hugs Kouki around the waist, pulling him back into a warm body. The voice continues after Kouki is pressed safely against them; “You should be paying more attention at a time like this.”
Kouki stiffens immediately after processing the voice and body he’s now pressed against and the sudden amount of slick leaking out of him. Someone managed to sneak up on him…fuck.
He catches a whiff of his captor’s (saviour?) scent; undeniably an alpha. Kouki’s nose is greeted by the richest and best tasting tea his father owns; it graces them with its presence only when the most important visitors are in Seirin. There’s a hint of something a little sweet and floral, an almost ripened fruit that Kouki can’t place. The alpha smells wonderful.
The unknown alpha chuckles, the sound music as Kouki practically melts more into the alpha’s embrace. “Are you that pleased with my scent? I am honoured; your scent is just as heavenly to me, Omega.”
Slick is gushing, flowing free like a waterfall as it cascades his thighs, to his calves and feet and into the river below. Kouki can feel his cheeks and ears warming as he almost purrs in response to this alpha’s praise.
Kouki doesn’t realize he’s tilted his head, showing off his vulnerable scent glands to the alpha. Not when the alpha starts sniffing him, inhaling his essence directly from the source, but when a pair of gentle lips brush the spot instead.
No, Kouki cannot give in this easily; not to an alpha whose face he hasn’t seen!
“Wait—!” Kouki stutters out in a hurry, attempting to break out of strong arms who refuse to budge.
“Alpha, please wait!” He cries out instead.
The alpha pauses, lips stilling, and Kouki struggles to hold back his whine.
“Yes, sweet Omega mine?” The alpha asks, words and voice oh so sweet. “Is there something you require of me?”
Since when are voices so…attractive? He wonders as tingles dance down his spine.
“I’d like to see your face,” Kouki manages to get out, wanting to prolong the (inevitable) mating as long as possible.
It’s silent for a moment, Kouki unsure if the alpha heard him or was unwilling to comply. He’s holding his breath, waiting for something when the alpha’s arm wrapped around his body moves, their hand now directly holding onto his waist instead. The alpha’s other hand settles on the other side, and slowly turns Kouki around.
Kouki’s looking down at the water when he’s done being moved. He takes a deep breath, readying himself, counts one, two, three and looks up.
He’s taller than Kouki, but that’s not too surprising since he also looks older, though Kouki can’t tell how old he is exactly. Perhaps around the same age as his mother and sister? His hair is fluffy and red—the same shade he saw earlier—yet not the same as Taiga’s hair. Instead, the colour oddly brings the skin of the delicious satsumaimo harvested last autumn to his mind. His eyes are the same shade as his hair, yet seem to take on an orangish hue when under sunlight.
His kimono, on the other hand, is darker than both his and Taiga’s hair, leaning more towards purple, with a matching haori overtop. Looking closer, Kouki catches sight of two mons, one on each side of his collar, indicating the three he can’t see on the back side. The mon are nakakage, the white outline sticking out against the dark colour of the fabric. Taking a closer look, the mon contains three leaves on the bottom, with three sets of flowers sticking above them in the pattern of five-seven-five; it’s not one he recognizes. Looking down, Kouki can see the alpha’s striped hakama. The whole set is incredibly glossy, and Kouki briefly wonders if it’s made of habutai.
“Are you some kind of foreign lord or something?” Kouki can’t help but ask. He winces after the words leave his lips, knowing he’d most likely get a smack on the back of the head and a reprimand for asking a stranger such a question.
The stranger doesn’t seem to mind it though as he smiles teasingly down at Kouki.
“Oh? What makes you think that?” He asks.
Kouki pouts, wishing the alpha would just answer his question first, but answers instead.
“Well, your kimono for one; it looks to be very high in quality and not to mention the colouring…” his gaze trails down to look at the kimono in question before flashing back upwards. “Taiga—my friend—also has red hair…not exactly like yours…but he’s from Jabberwock so I just thought…”
He looks away, feeling embarrassed all of a sudden. The alpha grasps his chin, making Kouki look at him again.
“You’re not too far off,” he says, a gentle and reassuring smile on his face now as he stares deep into Kouki’s eyes. “I was born here in Teiko, but I am half Jabberwockian from my mother. I inherited my hair colour from her.”
“Woah…that’s so cool,” Kouki says, too awed to realize that the ‘lord’ part of his question went unanswered. “…May I ask you another question?”
The alpha’s hold on his chin moves to caress his cheek. “You may.”
“What’s your name?”
He blinks at him, surprise evident at the unexpected yet completely normal question asked of him.
“You may call me ‘Sei’,” he answers. “‘Sei’,” Kouki repeats, testing out the name and finds that he likes it. “Hi, Sei; I’m Kouki!”
Kouki isn’t sure how he got here, laid on top of Sei’s haori on the forest floor. His obi has been untied, his kimono and nakagi undone and being brushed off his shoulders by enthusiastic hands, his white-patterned red juban now on full display to Sei.
Kouki knows his cheeks are undoubtedly as pink as the sakura blossoms back home as Sei’s eyes unblinkingly trail down his body, taking him in. Almost like he’s committing his whole being to memory. The thought causes more slick to gush out of him, dampening Sei’s haori and reminding Kouki of his current heat.
“Perfect Omega. Perfect Kouki,” Sei whispers, kissing down his neck, hands brushing back the thin overlapping panels of the juban, revealing Kouki’s flat chest. “You are so worth waiting all these years.”
Kouki whimpers, his mind starting to fog at the touch of an alpha; his scent and presence completely overwhelming him.
“How—ah—” Sei’s hand sprawled over his chest, his pinky brushing one of Kouki’s nipples, “—how many runs have you participated in?”
“Hmmm,” Sei hums, hand moving to one side of Kouki’s chest and squeezing. “My first Run was when I was 16 so…this is my eleventh Run.”
“Eleventh?” Kouki wheezes, sudden wet heat encloses around his left nipple. His back arches, pushing the bud further into Sei’s mouth. “Tha-that makes you—mhmmm—almost double my age.”
Sei bites and sucks his way from one nipple to the other, his tongue lavishing it in the same attention.
“…you must have been lonely.”
Sei pulls away, Kouki pushing his chest out closer, chasing his mouth. Sei leans in close to his face, their lips almost brushing, teasing.
“Kouki…you have no idea.”
The kiss is light and delicate, as if Sei is afraid of breaking Kouki. One hand comes up to cup Kouki’s cheek, tilting his head to get the perfect angle. If Kouki wasn’t already feeling dazed from his heat, this kiss would have no doubt sent him over the edge.
Too distracted by the kiss, Kouki doesn’t notice as Sei’s free hand dances its way down his body. His fingernails leave the faintest of white trails behind them, his smooth skin providing an easy gliding surface.
Kouki gasps into the kiss as sudden warmth wraps itself around his cock. Sei takes advantage, his wet tongue licking its way into Kouki’s mouth. His tongue traverses Kouki’s mouth, reaching everywhere as fingers stroke his mouth, leaving Kouki feeling out of breath and jerking into Sei’s hold.
“Sei, Sei, Sei, Sei,” Kouki chants into his mouth.
Sei pulls away, Kouki whining until Sei starts leaving a trail of kisses down his body once more.
“Your cock is so cute, Kouki.” Sei says, looking down to where he’s pleasuring him; Kouki can’t help but follow his gaze.
His breathing hitches on a moan, jerking shakily at the sight of Sei’s hand wrapped easily around his entire dick. Kouki knows he’s small and he knows that it isn’t very likely that he’ll continue growing following him presenting as an omega but…Sei’s hand and how effortlessly he’s contained inside…the difference in their sizes does something to him.
Kouki isn’t able to give Sei any sort of warning before he’s hit by his orgasm, cum shooting out of him and landing on Sei’s wondrous fingers and his own chest.
If Sei is surprised, he doesn’t show it. Working Kouki off as he rides his orgasm into overstimulation. When Kouki starts moving his lower half away instead of into Sei’s hand, the pleasure too much and bordering on pain, Sei releases him. He admires his handiwork, Kouki’s cum on his fingers, before sticking one in his mouth and groans.
Kouki blushes as he watches Sei eagerly lap at the rest of his covered fingers, licking them clean and leaving them sparkling with his salvia instead.
“Kouki—” Sei groans “—fuck. Kouki, you taste so good.” Kouki watches him lick his lips for any remaining traces of his cum, pupils taking over the red of his iris as he takes in the mess Kouki has undoubtedly become.
“I wonder…” Sei whispers, almost like his words were meant to be an inside thought. “...how does it taste?”
Kouki doesn’t get the chance to ask him what ‘it’ is before Sei is throwing his legs over his shoulders, pushing his knees into his chest.
“...Sei—ah?!” Kouki exclaims. Sei’s head is ducked in between his legs, his nose shoved between his cheeks and huffing in the scent of Kouki’s slick as if he’d die without it.
Sei grasps both of his cheeks, his hold firm as he spreads them apart. Kouki can feel his rim twitching at the sudden air. He tenses at the feel of something suspiciously wet, firm and soft landing on his hole, it curls inside, coaxing out more of Kouki’s slick to drink it.
“Omega smells and tastes so good,” Sei says before diving his tongue back in for more.
Kouki cries out, grinding onto Sei as he tonguefucks him, slick leaking freely and no doubt covering the lower half of his face. His hands grip as tightly as they can on Sei’s locks, switching between pulling him in closer and attempting to push him away, yet Sei doesn’t seem to mind. He simply continues exploring his insides with his tongue, holding Kouki still as he devours him.
Kouki cums again in no time, cock pathetically spurting more cum onto his chest.
“Se-Sei…please…” Kouki whimpers, fists full of Sei’s hair and tugging him away from his feast.
His alpha growls, his nails digging into the soft flesh of Kouki’s asscheeks in warning. Kouki shivers and a whine escapes him, unable to deny Sei. His growls die down, and the slick sounds of his tongue moving against his hole and his eager slurping start up again, drowning out Kouki’s whimpered pleas of surrender.
Sei’s tongue leaves him, only to be easily replaced by two of his fingers. The entrance is smooth from the mix of Kouki and Sei’s bodily fluids. Kouki’s head jolts back, a long moan escaping as they hit something sensitive inside; Kouki misses Sei’s hooded gaze and his tongue licking up what it can reach off his face of Kouki’s slick.
“Al-alpha…please. I—ah—need your knot,” Kouki begs.
Sei kisses just under both of his eyes, the scent of Kouki’s slick on his breath as his lips pass over Kouki’s nose.
“One more, Kouki.” Sei adds in a third finger, scissoring them, stretching Kouki. “One more, Kouki, and then you can have my knot. Won’t you be a good omega for me, hm? Don’t you want to be your alpha’s good omega?”
Kouki bites his lip, the pleasure is too much. He hesitantly nods; as a reward, Sei crooks his fingers, hitting that spot over and over again.
Sei curses, and it’s as a fourth finger is breaching him that Kouki realizes that he’s been the only one being pleasured this entire time.
“Sei-Sei—please—you to-too. I want to pleasure you too,” he struggles to say, moaning and groaning the entire time. He reaches down, intending to undo Sei’s obi and slip through his kimono when Sei grabs a hold of his wrist, stopping him.
“Oh, sweet Omega,” he coos, moving Kouki’s hand away from his obi and towards his mouth. He clasps their hands together, giving Kouki a kiss on each individual finger. “We have all the time in the world for you to do that…however, I’m afraid my knot won’t make it to your hole if you do that now.”
Kouki can’t say for sure whether he’s imagining it or not, but it’s almost as if Sei is pumping his fingers in and out of him with a new purpose. There’s just something different about the way Sei’s fingers curl inside of him.
His third climax hits him before he knows it, cum barely leaving him at this point. He flops back onto the haori below him, limbs completely giving up.
Sei hums as he slowly drags his fingers out one final time, Kouki too sensitive and tired to do much more than pant and whimper. Sei licks his fingers clean, Kouki lost in his nonexistent thoughts as he takes Sei’s distraction to regain control over his breathing.
“Kouki,” Sei says, “look at me.”
Kouki can’t say for sure how much time has passed but most certainly enough for his breathing to return to normal.
He almost loses his breath again when he glances at Sei.
He’s naked, his obi and all layers of his kimono are off, including his juban. His body is pale and well endowed. Kouki feels drool start collecting in his mouth before he forces himself to swallow it down. His eyes trail down his body, ignoring the sweet chuckle above him and land on Sei’s dick.
It’s…large. Long, girthy, and pale. His veins are prominent and the tip is noticeably red, no doubt from how long he’s been hard. Sei is jerking himself off, spreading the precum leaking out of him along the entire shaft. Kouki also notices that Sei most likely wasn’t lying about his knot earlier, the base of his cock is thickening already.
Kouki meets Sei’s eyes again, his oversensitivity completely forgotten. Sei smiles at him, one full of confidence and awareness of the effect his body has on Kouki. It sends a dangerous thrill down Kouki’s spine.
“Omega,” Sei says, his inner alpha coming through. “If you want my knot, you know what you need to do.”
Now, if this had been any other moment, if Kouki hadn’t had three orgasms wrung out of him, hadn’t seen how hard Sei is, and didn’t have ‘knot’ and ‘Alpha’ on a continuous loop in his mind, he would have felt a little insecure and embarrassed, not certain if this is what he truly wanted.
The possibility of not doing this didn’t even cross his mind.
He licks his lips, and sits up, turning over onto his hands and knees. Kouki leans down, pressing the side of his face into the haori-covered ground. Breathing in the mix of the natural earth and Sei’s heavenly scent.
Reaching both arms behind him, Kouki runs his hands over his cheeks, fondling his own ass and feeling how soft it is. The wet sounds of Sei jerking off and him groaning fills Kouki with a sudden surge of smugness. Hearing how affected his alpha is by a little teasing, Kouki decides to be nice. He digs his fingertips into his skin and pulls outwards, exposing his puckering and oozing hole.
“Knot me, Alpha,” Kouki says. “Mate me, knock me up, breed me full of your pups. I can handle it.”
One moment, Sei is growling behind him, the next, Kouki is choking out a moan, never having felt so full before.
Sei’s hands land on his hips, fingers gripping into his skin, bruises surely to follow. He pounds into him, fucking him so deeply and punching moans out of Kouki.
“Fuck, Kouki,” Sei moans into his skin, teeth scraping against his shoulderblade. “You take me so well. What a good omega. So fucking good for his alpha.”
Kouki mumbles something incoherently; even he’s unsure of the words leaving his own mouth. He’s fairly certain that it’s a mix of pleas and telling Sei how good he’s making him feel though.
“I was going to be gentle…so gentle and nice—fuck—for our first time…but you just wanted to be stuffed full, huh? Fucked to the brim with your alpha’s cum?”
“Mhmmm—yes, Alpha. Please…I need it so bad—RIGHT THERE! Fuck, Alpha, right there please please please.” Kouki meets Sei thrust for thrust, drool now freely leaving his mouth and dripping down his chin to the haori below.
Neither lasts much longer. Sei thrusts in once, twice, and a third time before the knot prevents him from pulling out. He grinds into Kouki, hitting his special spot inside, Kouki’s cock letting out watery cum. Kouki rides it out, whimpering as Sei bites down on the back of his neck, claiming him. It doesn’t take much more, Kouki tightening around him, before Sei is cumming inside, locked in.
His lids feel heavy; eyes struggling to stay open from how exhausted he suddenly feels. Kouki’s heat-raddled mind has finally calmed down as Sei is stuck, connected to him as he continues to cum.
He can feel Sei let go of his neck. Sei laps at the mark, a soothing sting as he does so.
“...rest, Kouki. You deserve it,” Sei whispers, turning them onto their sides. He wraps his arms around Kouki, snuggling them close together. “You did so well for me, so perfect.”
Kouki doesn’t wait, and his eyes close, falling into a much needed sleep.
