Work Text:
It was unbearably warm this morning in July, the rays of the sun soaked into the dirt path, radiating its warmth upwards like a broiling oven. How unendurable…
Or maybe it was just that way to Tanjiro, the young omega holding the straps of Nezuko’s box like a lifeline for something to ground him. He felt so uncomfortable, everything felt muggy and tacky, his breath beginning to come off in ragged huffs. Desperate for cool air in a sea of humidity.
‘Am I getting sick?..’ He’d hardly repressed the quiet whine that scraped its way up his throat at the painful sensation in his legs. His eyes were glassy, clouded and watery as if he were holding back a flood of tears.
He felt fine just the other day, capable of moving about during the mission at hand. What happened?
Tanjiro had managed to push through an hour at most of his suffering, his clothes felt too tight, too damp, it was asphyxiating. His throat felt dry, eyes fluttering as his vision went spotty. “Not.. Good..” He barely rasped out another noise protesting his worsening exhaustion before everything went dark.
Unbeknownst to the unwell slayer he had fully collapsed on the dirt path, Nezuko’s box thankfully remaining closed yet that didn’t hide her distressed mumbling to the sudden weight shift and the lack of response from her elder brother.
No more than a span of a few minutes Matsuemon flew above, taking note of the distress and rushed off in a flurry of feathered wings in search of aid.
Lethargy.
That's the surrounding feeling Tanjiro felt upon awakening, eyelids heavy like lead, gaze struggling to compensate to the darkness of the area he resides within.
There was a distinct pressure blanketing his legs and as he slowly began to rouse, he realized he was stationed within a room. The heavy scent of antiseptics and wisteria advised that he was back at the Butterfly Estate.
The symptoms from earlier were muddled, housed in the back of his mind in wait yet not entirely vacant.
Sanguine eyes shifted down towards the end of the cot he rests upon, taking in the form of his young, sweet little sister in deep slumber. There were dried tearstains beneath her eyelids, the scent of stress hidden amongst that of rest.
She was crying. Or had been.
How long has he been asleep? What day was it? 'I'm so tired…'
The next time he woke he was greeted by the sight of Shinobu hovering by his side, despite the cool demeanor she masked, worry was evident in her scent. Or from what Tanjiro could tell.
“Kocho-sa—” His mouth felt so dry, tongue heavy and his voice cracked as he tried to greet the beta woman. She raised her hand, quickly reaching for water and helping him sit up. “No need for formalities, dear, just hydrate. Drink slowly.” The water she held out to him had a peculiar scent, like some form of earthy tone yet not too overwhelming to his sense of smell.
It was much like her to have the remedies for fixing him right up. He offered a timid smile, appreciating that she tilted the cup to his lips due to his strength being greatly depleted. “Your fever has yet to fully subside, though it is not as worse as it was earlier.”
With a voice much of a worried mother Shinobu huddled near the unwell omega for the time being. Checking on him every hour to refill his water and administer medication when needed be.
The day blew over Tanjiro like a silken stream, it was fast and felt like a fever dream that made little sense. As if he lived it but not. As if he was there, but unable to recall much. Despite it actually happening.
It wasn't until the next day that his condition grew worse, much to the displeasure and worry of his friends, sister, Shinobu and estate nurses.
“Tanjiro?” she’d ask as she picked up the empty bowl by his bed, what was once porridge was now scooped clean. It's a blessing he's able to hold his food now. “Yes, Kocho-san?”
His voice was still wilted and fluttery, his strength returning yet maintaining a specific amount of fatigue in his structure.
“When was your last heat?”
Heat?.. He doesn't recall if he's ever dealt with one before, sure he gets little spells of warmth and neediness, but those have yet to be fully quenched. It wasn’t ever unbearable, mostly a minor twinge that he’d easily snuff out with his fingers. If he ever got the alone time to do so.
“U-Um.. I don’t think I’ve… Ever had a heat.” His voice was so small, his form involuntarily sinking into the cozy blankets out of defensiveness.
Shinobu eyed how he reacted, noting his spiking scent and how he has somehow managed to build a makeshift nest in his own ward bed, perhaps without his knowledge. “Tanjiro, dear.. Would you mind coming with me?”
A new room greeted Tanjiro as he was aided in walking down the halls, it was so much further from the other resting areas where slayers were either chatting lowly or sleeping to recuperate. This room in particular looked simplistic, spacious but rather stuffy. There was a window though not much of a sizeable view. “Kocho-san?..”
She could sense his uneasiness, and turned to offer a warm smile, the kind that creases her eyes softly. “It’s alright, I can sense your worry. This is just pure speculation, but I am sure that what you’re dealing with is your first-ever heat. It’s completely normal for it to be late to present itself so there’s no need to stress. Alright? Make yourself comfortable and I will return shortly with a few things.”
Her voice was always so airy and soothing, something that Tanjiro could lean into with his guard down. Perhaps it was because she reminded him of his mother Kie.
“O-Okay..” He stood there, arms crossed over himself in a makeshift form of safety, tugging at the sleeves of his patient-wear as he looked at his surroundings. The walls were a dim mauve-beige that had intricately designed stencil-work of black carnations and lotuses painted from top to bottom.
The flooring matched the entire estate, smooth birch wood. A single large, padded futon and a small nightside low-legged table with a singular oil lamp. Peering out the small window that was only the size from the top of his head to the waist— He took note of the setting amber sun. Just how long had he slept?
The window itself couldn’t open like the others, it only provided a view of the gardens blanketing the sides of the estate, in a way It was a blessing. It offered privacy with a beautiful view of nature.
But as the minutes ticked by, warmth blossomed across his skin like prickly thorns prodding every open pore on his body. It grew unpleasant, once again his clothing felt too stiff, too warm, and abrasive. Sticking to his skin which was beginning to produce perspiration mixed with the oils of his pheromones.
Shinobu had yet to return inside the room, but he did hear a distinctive shift by the door, it was so quiet he didn’t notice until he scented that the beta had left a tray of food and a packet of herbal medicine. Stepping closer he noticed a medium-sized white box placed beside it, curiosity hit his senses immensely.
Once he set the tray aside he went right for the box, sitting down on the large soft futon and peering inside.
He almost clamped the wooden corners atop his fingers with how fast he shut the lid, his face absolutely ablaze. Tanjiro wanted to question precisely why Shinobu gave him such things, yet after a moment of thought he recognized the purpose. ‘Ah… How embarrassing..’.
Tanjiro barely touched his food or medicine for the time being, his position in the same spot prior, though he was shifting in place. Writhing. Tilting his hips side to side upon the mattress as he clutched a dense item within his palms.
His thumbs worked over the ribbed material as it had some form of give to it, but it was mostly firm and smooth.
The reason behind Shinobu giving him a phallic object wasn’t lost on him, he wasn’t foolish. He knew what it was for and why, he was entering his heat phase.
Although, this is a new experience.
The room felt so hot, it was stuffy, despite the lack of clothing on the omega he was left sprawled on his futon, skin clammy with sweat and breaths coming short and uneven. The symptoms he felt before were nothing compared to this, it was already the morning of his birth. He should be with friends and his sister, celebrating his 15th birthday with smiles and food aplenty! He’s sure of it.
But here he was, facing the ceiling whilst sprawled on his futon, borderline hyperventilating as he rubbed his thighs together, slick freely oozing from his puffed folds. Discomfort. Pain. Emptiness. It was awful.
Nothing could compare the intense need and ache he felt today. Yesterday and all the other days, could never.
His thoughts whirled and varied in intensity. Though what he memorized most was how much he missed his alpha... Well, the Flame Hashira wasn’t his alpha but… An omega can dream, can’t they?
Their relationship was interesting at best, ever since the battle, after they— After he survived the mission from Mugen, from that heartless beast that nearly killed him. Things were foggy at best.
The Pillar was operating fine on his own day to day, if not weekly missions and tasks. His healing was slow, things changed when he’d have to work around only one working eye and idle abdominal pain that further worsens when he uses breathing styles. The fact that he won't retire is what stresses Tanjiro the greatest.
‘Rengoku-san..’
His infatuation for the man is an understatement, how his facial features seem odd to most yet to him they are beautiful in their own way. His thick brows, joyous smile, boisterous voice, and his lips. Goodness, his lips. They look so soft. His hands look like the perfect representation of a swordsman hard at work, at training.
Robust, concentrated, he wonders if his palms are rough or smooth.
They look to be both.
Just the roaming thought of the older alpha has Tanjiro’s face running hot. A fresh pull of slick further wetting the space between his legs as he reminisced. Trembling fingertips traversed across the bed in search of the object that was gifted to him earlier, a warm bloom of arousal settling heavily in his stomach as he grasped the base of it, slowly moving to prod the phallic head at his entrance.
It wasn’t absurdly large, but it was girthy enough to pry him open, the material’s hardness was uncomfortable at first. Resulting in him pulling it out completely, even if he’d only gotten merely the tip inside.
Taking a deep breath, he relaxed his hips and let his legs lay flat on the futon, eyes closing as he focused entirely on the sensations below. Slowly dragging the toy’s head through his folds and intentionally circling it around his budding clit that throbbed from its hood.
In a way he didn’t want to penetrate himself, he didn’t want this damn toy, he wanted Kyojuro. It was all he could think of as he rubbed the ribbed edges of the object through his glistening pink petals.
Would Kyojuro be bigger than this? Tanjiro can only imagine, it would make sense if he were. The Hashira is taller than him anyways, he’s older and stronger. With a body that well sculpted, how can he not be?
Tanjiro did little to suppress the bubbling whine seeping past his wetted mouth, smaller fangs nipping his bottom lip as he picked up the pace at which he ground the textured sides of the toy against himself. Strings of slick pulled at the object, coating it thoroughly with the excessive amount running down the crease of his thighs and ass as he lifted his hips to slant towards it with fervor.
His head was so fuzzy, stuffed with cotton as simmering heat pooled deep in his stomach, nerves drawn taut like brittle wire. He was close, so close yet so very far. Every moment his body quaked near what felt like an orgasm, the peak would never come. His bodily temperature steadily rose as he sought to quench the thirst of his animalistic desires more than anything.
After the fourth failed attempt he hissed through his teeth, tossing the toy elsewhere in the heat-room and took to using the roughened pads of his fingers against his soaked rosy bud, continuously rubbing in circles along the underside.
While one hand was occupied rolling a distended nipple between nimble fingers, he took to using his other to slip in at least his middle and ring digit into his oozing entrance. The sound of his slick sticking and being pressed or tugged from his body alone was absurd. So humiliating and obscene..
He relished in thoughts of the Flame Pillar in this same room, how the adult alpha’s scent would blanket his senses with the hint of his musk, spice and smokey aroma. Tanjiro rolled onto his stomach, fingers curled deep in his dripping cunt as he humped his hand desperately, huffing into the pillows scattered across his already messed futon from endless tossing about.
It took immense effort to hold back the keening mewls rising from his throat as he deliberately dug his fingers against his erogenous spot. The spike had his nude form sweating heavily, he felt as if his body would melt into his own bedsheets as he pleasured himself to the thought of the Hashira. That toned body he’s only seen once in training, those piercing eyes and when the man would move a certain way he was sure that if he’d look close enough without getting caught. A sizeable mound beneath that fundoshi.
He wants to know the taste of him, his seed thick on his tongue.. How feral would the alpha fuck him? Break him in. A shorter, young virgin omega in heat, pliant and unable to deny a thorough breeding if he came through the door right this moment. Better yet, he wanted him to fill deep in his womb. He wants Kyojuro to mark him, bite him forcefully and have him screaming. He wants…
“P-Pup.. Puppies..”
The omega’s body seized with him lifting his hips on quivering knees as he came with an embarrassingly loud cry, fingers stilling inside his pussy as slick and liquid arousal sprayed out in a sticky, creamy stream of his own spend. His thighs trembled as he looked between his legs, his hand was drenched all the way to his wrist. Along with the disheveled blankets amongst his futon.
But the simmering ache of his heat only worsened, his fingers could only do so much. The pain was excruciating, he wanted to be knotted, to be bred full. To be pupped. Sure he was young.. But it’s not wrong to think that way, right?
He just wanted Kyojuro…
With a creak of her office chair Shinobu leant into her desk, paper scrolls were scattered all about depicting the anatomy of the male omega, heat cycles, and what was normal in occurrence or abnormal to consider worrisome. So far to her studies and taking a secluded blood sample from the young boy— He was remarkably fine. Interesting to observe, due to his maturing heat coming so severely so soon.
It was then a thought came across suddenly, the day of his birth. Of course! He’s 15 now, right? Surely he’s matured as a young omega by now. That cloying scent made it obvious, and it was alluring even to her, it has a remarkable appeal to it. Enthralling at best, yet she doesn’t have a powerful keen sense of smell like alphas and omegas have. Especially Tanjiro. She’s merely a normal, unexciting beta that makes her life worthwhile to be a doctor to those who need the utmost care.
There’s nothing to complain about here.
Well, there could be a few things. The sudden barrage of commotion echoed down the once peaceful halls of the Butterfly Estate, various reverberations of footsteps thunking on wooden flooring and one very distinctive voice.
Shinobu set down her ink brush, allowing the paper to dry. She stood from her desk, pinching the bridge of her nose with an irritated sigh. “Of course..” It was only a matter of time before he showed up, surely his crow received the news and reiterated it back to its master.
It was as if he couldn’t run any faster, weaving through the trees and vaulting through the slopes and mounds of the mountains before he skidded to a halt in front of the gates to the Butterfly Estate. He had received the news of his ome— Of Tanjiro falling ill. He had no knowledge of anything else but his deteriorating health and he didn’t wait a second longer before he took off in full sprint.
It was so sudden, his haori littered with dirt and leaves, hair with small twigs sticking from it as he approached the Kakushi standing outside the door, heaving with the wild gaze of someone who just traveled out of sheer stress alone.
“L-Lord Rengoku! Ple-“
“Please allow me to go inside, I need to see Kamado!” He declared whilst simultaneously dusting himself off and ridding as much from his wild fiery mane as he could to at least seem presentable for the young boy.
“I’m sorry sir we cannot allow that, please don’t come any closer! He is unwell, Lady Kocho’s orders!” An older beta, Kakushi, held up her hands with worry in her tone. And Kyojuro was no fool, he could see through her reaction like a glass window. Though as he approached closer to where the two stood his nose picked up on something absolutely delightful.
It was a thick gratifying scent, reminiscent of honeysuckle, fresh crackling wood of a fire and charcoal.. Charcoal… Tanjiro. And by the gods, he smelled divine. It was idly dull, noting the time that has passed since they came through. This was no mere sickness, it was the smell of an omega in heat. ‘His first..’
“I am sorry, but I must pass through now. Do not try to intervene.” Kyojuro’s tone was low, teetering on a growl that clawed in the depths of his lungs as he breathed in the scent of Tanjiro.
It was so strong and potent, as if the omega was right in front of him, beckoning him. Just imagining how intense and suffocating it would be up close and fresh had his cock throb beneath his fundoshi and hakama pants.
“S-Sir!” The other Kakushi, a male beta, stood ramrod straight when a sight of a slitted pupil darted his way, piercing through his very being. ‘Forget it. I do not get paid enough for this…’.
As it turns out the loud commotion Shinobu had overheard wasn’t the workers of the building coming to solve the dispute upfront, but rather running from the cause of it. She stood there outside the door of her office to see the Flame Hashira himself stride up to her with purpose.
Upon closer inspection she noticed the veins protruding across the features of his face as if he were straining to keep his composure as authoritative as possible.
“Good evening, Rengoku! It is quite a surprise to see you here! I presume you’re looking for Tanjiro?” Shinobu’s tone may have sounded saccharine to those on the outside of the Hashira Circle, but if you knew one thing. The sweeter her tone, the more furious she truly was. Because of this mishap, she was seeing Kyojuro as nothing but a damn nuisance.
And if he truly thought he could barge in and take advantage of little Tanjiro while he was in heat. Well, she had a special concoction of a tranquilizer just for this occasion.
This heat spell if anything strengthened his already impeccable sense of smell and he may not have exceptional hearing like his friend Zenitsu, but he knows the flooring scent of a distressed alpha and booming tone when he overhears it.
“Rengoku-san?..” His voice lilted barely a whisper, it was weak no matter how often he drank the medicinal water and took those capsules. Sure they stalled some of the pain, but they did little to aid the broiling throbbing discomfort between his legs in the core of his body.
There seemed to be some sort of scuffle outside his door, there were a few words spoken but he was almost positive he was listening to Shinobu practically hissing at Kyojuro; who from the bold cast of a shadow was close by.
“Will you just— Will you just let me see him!?” Kyojuro damn near yelped as the smaller Hashira grappled his left arm and brought him to the wooden floor with a loud slam, constricting her legs around the limb while she extracted a filled syringe from her sleeve.
“I already told you he’s in heat, he’s unable to protect himself and I will be damned if I let a brute like you get your hands on him! He’s still so young, Kyojuro!” The woman lifted her hand back, prepared to drive the cold needle of the syringe into the man’s arm to temporarily subdue him but the door to Tanjiro’s room swung open.
“Wait! Stop!” There he stood on wavering legs, covered in one of the extra blankets he’d found in the closet. The cloth just barely covered down to his knees and a haze of the omega’s potent scent flooded the halls immediately.
Kyojuro laid there with wide eyes, dilating as he took in that rich scent tinted sour from the pain he was in. How long has the boy suffered like this? Was he not given enough aid to help him? It irked the Flame Hashira to no avail even if he laid on the floor in a close call with being paralyzed.
“Tan.. Tanjiro..” Kyojuro peered up at the omega who was as stunning as ever, despite looking unkempt, gleaming with sweat and the scent of slick perfuming from their sunkissed skin. He was lovely regardless and the alpha could feel the growing itch in his jaw.
“Please let him go, Kocho-san I.. I want him in my room.. Please.” The boy looked so fragile and it was completely out of character for him. Someone who was always stubborn, resistant, and taking the brunt of everything that an elder brother should; to be sapped by this state of body and mentality was a crime. Kyojuro was deprived. He wanted to soothe the omega. His omega.
“Tanjiro…” Shinobu was merely a hair's breadth apart from puncturing a vein along the Flame Hashira’s arm, ready to fully put him to sleep that’d keep him under for a good amount of hours. But here Tanjiro stands on trembling legs like a newly born foal; eyes like jewels wide and glassy as he pinpointed the alpha in question.
“I promise I’ll be okay, Ko-Kocho-san.” Tanjiro offered a bleary smile to the Insect Pillar, the kind of smile that felt like a wilting icy flower, yearning for warmth. She sensed nothing but honesty through the boy’s demeanor. Even if she was extremely reluctant to allow this grown alpha to travel into the young slayer’s room.
It was the omega’s wish, and an omega in heat has every right to decide who enters their nest, their sacred place at the time being.
“As you wish…” Unfortunately, she was unable to put her foot down on this one. It would seem absurd to others outside and even inside of the vicinity. But thankfully the heat-room Tanjiro was placed within is sealed and soundproof. Perfect for either an omega or alpha going through intense spells of carnal needs.
Usually something like this was rare to occur in her estate, she’s used to taking in those extremely injured or on the brink of death— Or even, in Tanjiro’s case: All three plus an impending coma.
She released Kyojuro with a drawn-out sigh, brushing off her uniform as she stood, violet hues trained intently on the alpha as he slowly glanced to the smaller omega in front of him. He was clenching his fists so hard it reduced his knuckles to white, his self-resolve chipping away every minute he stands here inhaling such delicacy.. “K-Kamado.”
“Yes, you can come in… Rengoku-san.” Kyojuro was dumbstruck that someone as sweet and delicate, no, someone as fierce and generous as Tanjiro would allow him of all people into his personal space. Sure they teamed up and worked together in the past but..
He still has moments of doubt, recalling of how he was so adamant on his and his sister’s trial to end in unbridled punishment. Does he really deserve this?
He doesn’t see himself as a worthy alpha, he’s wounded permanently, to some degree hard of hearing and blind in one eye. What is desirable about him? Kyojuro doesn’t sense it, his confidence has weakened over time due to the previous battle that almost took his life— And nearly killed Tanjiro from immense stress and heartbreak.
They aren’t even a bonded pair.
Tanjiro held the door to his room open, shooting Shinobu one more glance and the kindest most reassuring smile before Kyojuro made his way through and the door was shut with an audible lock.
She exhaled once again, staring at the door for a minute longer before wandering back towards her office.
Tanjiro was deep into his heat yet coherent enough to make considerable choices that were sensible at least, for now. It was up until Kyojuro's heady aroma caressed his senses that the omega gave a trilling purr; knees almost buckling as he walked closer to the man.
The Hashira himself lifted his hand to brush his fingers through the redhead’s unruly hair, still soft and silky despite it all. He opened his mouth, closing it at a loss for words.
“Tanjiro.. Are you sure? I can't promise I will hold back.” He looked so worried and if Tanjiro wasn't so damn horny for him he'd find it endearing. But right now he didn't want to hear any of it. He wanted fewer words and more touching.
So he gravitated into the alpha’s space with a soft hum, the blanket he was clutching is dropped and forgotten on the floor where it pooled around his feet. His body bare for Kyojuro's viewing.
And observe he did with a gaze so famished he had to bite the inside of his cheek to not immediately mount the omega here and now, with a youthful figure that was tender but scarred, toned and grown to excellence.
“Are you going to just stand there and not touch me already, alpha?” Tanjiro murmured into the others chest, smaller hands working at the Pillars uniform buttons to expose his torso. Kyojuro almost jolted, feeling the intense heat radiating from the boy’s skin even through the thickness of his clothes.
Alpha.. He called him alpha… “Y-yes my boy! Forgive me. Y-you’re just..” He's just what? Delicious? Divine? Otherworldly? A blessing? Words cannot express the amount of adoring lust this man feels for the slayer before him.
It wasn't until Tanjiro huffed impatiently at Kyojuro's lack of nudeness that the alpha rushed to remove them. Eyes like burning embers trained on the figure that walked back towards the futon, or rather his nest.
Tanjiro watched him undress, soft tongue curling out against his lips to taste the aroma wafting from the alpha- And when he finally, finally dropped his hakama and fundoshi to expose that mass of girth, Tanjiro could feel his body tremble with a shaky inhale. A fresh ooze of slick trickled down between his legs at the heavy scent of that raw masculinity.
It made him moan beneath his breath, legs tilting open when he laid back on the bed, pupils fully blown wide indicating that the young boy was absolutely enveloped by his heat spell.
“Alphaaaa..~” He meekly purred, rolling onto his stomach and lifting his hips high, curving his back to where his shoulders were flat on the mattress. Clearly presenting that sopping cunt for the man to breed.
Kyojuro audibly swallowed around a lump in his throat, all his instincts were snarling, gnashing their teeth at the back of his skull. Howling for him to fully take advantage of this fertile youth, just the exposure of those puffy pussy folds had his mouth pooling with drool and venom.
But behind the rage of dominance was a clearer mind, requesting he take his time to break them in.
Savor it.
“Yes, my omega.” Kyojuro's warm breath fluttered behind Tanjiro's left ear, rustling his hanafuda earring and making the boy whine out. He was wiggling his hips, attempting to push back when he felt the fuming warmth from the alpha's cock. “P-Please alph— AAH!”
Tanjiro's legs quaked, his face burning so, so hot as he smothered it into the rumpled sheets below. The sensation of a searing rough tongue curled out to slide from the entirety of his pulsing clit, through his slick honeypot and pressing a filthy kiss to his fluttering anus.
Kyojuro had the young omega's hips in a rough grip, extending claws digging into plush flesh perfected for birthing all while he lapped and drank in the gathering wetness of the very same boy who tried so hard to ride his face.
Oh, how he squeaked. His cries were delightfully noisy. Little claws of his ripping into the bedsheets as the alpha devotedly ate him out; his tongue dipping into that tight virgin cavern over and over, curling every which way possible just to have him sobbing.
“I-IM.. CUHMMIINNGH!”
That vocalization was the only warning Kyojuro got before he felt the omega cum into his mouth, wetting his face and chin in the process. Yet he didn't stop there, he kept a firm hold on their waist and lifted them so he could sit on his knees.
Tanjiro just dangled there, only his arms and head remained on the futon as Kyojuro held him up, mouth pressed deep into his backside as he resumed to pleasure the already overstimulated omega who tried to wriggle away, pleading, body jolting at every lick and suckle to that bundle of nerves.
“A-ALPHA!! Knot! P-puppies!”
Tanjiro wailed, feeling his slick run through the trimmed pubes of his cunt and trickling up his heaving stomach. He could barely breathe right, stuck hyperventilating and whimpering at every rough lap from the alpha. He wanted more! He wanted to be taken! Mated!
There was no need for words, not when Kyojuro was so enraptured by the boy crying out for his seed. That velvety flushed sex felt so smooth and silky, he'd never tire from feeling the texture on his mouth.
But what kind of alpha would that make him to ignore a crying omega in heat? He was just all too eager to claim him.
It's been a thought ever since they grew close after Mugen. After he healed and found the young one at his side at all times. And when Shinobu, Aoi or anyone else dragged him away to eat and care for himself, he always wandered back and even crawled into the same cot.
Tanjiro was the perfect omega. Motherly, strong, fearless, and capable of such devotion and warmth the sun could never win against.
He needed him.
He wanted him.
He deserved him.
He was adolescent, fruitful, and absolutely supreme. Kyojuro has never come across an omega so suitable to him on the near fateful day they met. To have their scent blooming in his mind as they napped and fought on that train. It took every fiber in his being to not ask the boy for marriage then and there.
But now?
Now he can achieve what he's always wanted. He can finally claim him. Ravage this little body and carve him to take it all. To be his wife, his omega.
'Mine. All mine..'
Kyojuro gradually released his bruising hold on the omega’s waist, though when they struggled to shift themselves back in a poor attempt at seeking the alpha’s cock, a large palm pressed down amid the boys back, completely restricting him.
The omega wheezed out a raspy yip, voicing his displeasure at being denied such a thing. “Alpha please!” He almost wanted to cry, his hips lifting in small fractions as he rubbed himself against the futon.
Kyojuro rumbled a lowly purr that rippled from his throat, bordering a groan as he situated himself behind the smaller male who so feebly tried to do things himself. Though it was so delightful at watching their supple rump move up and down as they massaged those glossy pussy lips on a suitable surface.
He wouldn’t be a very good alpha if he didn’t take care of his omega, now would he?
“Hold still.” He ground out, planting both hands on the curve of Tanjiro’s back as he steadied, lowering his gaze down to the omega’s cunt that he slowly began to rut the girth of his cocktip against. The flared head barely caught on the small rim of their pussy and slipped upwards, stroking between their plush asscheeks.
Kyojuro couldn’t help but rub himself against the boy’s backside for a bit, finding comfort in their helpless mewls and begging cries.
“Pleeahh.. Pleaahse! J-just—F-Fuhck..” Tanjiro’s voice was stuttering as bad as his brain, tongue lulling free from his wet mouth as the large alpha behind him slowly prodded the wide tip of his cock against that small slit.
“Y-Yeesss!~” It felt wonderful being compressed into the bed as the man started to widen him, every minuscule push had the omega’s legs trembling. Of course due to the size difference it ached, but only minorly. Due to the alpha’s preparations prior, Tanjiro mainly felt nothing but bliss. The man he loved leisurely deflowering him.
Red-hot intensity settled like humid vapor in his brain when the Hashira bottomed out with a deep grunt, his lush opening applied with pressure. “My boy..” Kyojuro clamped his jaw shut and grit his teeth with a hiss “I can’t.. I can’t hold back, forgive me!”
All his resolve and self-control were instantaneously discarded. Being surrounded by compact walls that gripped him so frequently had the alpha’s higher mind shatter completely. He gave the omega little time to acknowledge and let alone respond to his words. He just barely pulled halfway out, watching that tight snatch being tugged back before he snapped his hips forwards and violently, submerging himself completely in that succulent dripping cunt.
Kyojuro drilled himself deep within that opening, pushing and pulling slick from the young boy’s body as he shrieked and wept. Scraping his nails along the already damaged bedsheets as he was impaled near insanity. “G— GGHUH!- A-AAH-ALPHA!”
Tanjiro was so involved in his heat that the man’s dick practically ramming against his cervical entrance at every downward thrust, threw him closer and closer to yet another climax. Every pull resulted in the alpha’s cocktip brushing along his g-spot; and every push had him embedded so thoroughly in the young slayer’s pussy that his voice cracked from just how loud he yowled.
‘Any harder and he’s surely going to break me in half!’ And that alone sounded utterly magnificent, it was a blessing the room was padded completely to maintain scent and sound. He was sure that by now someone would think he was being wrongfully mounted against his will.
But no, these cries were of nothing but sheer ecstasy, even if he was writhing and trying to pull away from the alpha due to the amount of unrestrained stimulation. How feral the older man was growling from above, how aggressive he trapped the petite omega and fucked into him like he was nothing but a cocksleeve had Tanjiro salivating excessively.
His ears were ringing deafeningly, piercing into his head in a throbbing headache as he saw nothing but white, the man had struck something spot-on it had reduced the omega to nothing but a rambling puddle of spend.
Tanjiro’s feet were tapping repeatedly against the mattress as he withstood a feeling so mind-numbing he couldn’t tell just how loud he screamed. His skull felt like it would be split open, the pain muddled his senses and blended fluidly with the unfiltered pleasure Kyojuro resumed to deliver.
The larger alpha chuffed pridefully at the near-thrashing boy, savoring the sight of his little pussy struggling to compensate for his size when he clenched and came around him.
“Kii— K-Kiyo..”
It was too much, even for his immense desires. It was too much! He unfortunately blacked out momentarily after his orgasm, slumping flat on the bed.
Kyojuro stalled immediately and gave a startled noise “T-Tanjiro!?”
He wasn’t out for too long. Next he woke on his back, draped in the warmth of a sturdy figure towering above him. There was a distinct pressure pulling at his entrance and he stiffened with a shuddering gasp.
Kyojuro had him boxed in with his forearms planted firmly beside his head, hips fitting perfectly against the omega’s as he slid himself back into that slick cunt, large hands eventually moving to position the smaller male in a half-bend.
“K-Kyo!” Tanjiro practically squealed on re-entry, his walls constricting so tightly around Kyojuro’s cock that smoothly slid to and fro. The heavy sound of skin contact was deafening to his senses and every hit to his cervix had him straining for air.
In this position Tanjiro was able to wrap his arms around the back of Kyojuro’s neck, nails digging into his shoulder blades as their glistening skin slid against one another in a magnificent display of friction. It was such an intimate experience, to finally be so close to the one you’ve cherished for so long. So many nights Tanjiro would lay in his bed and fantasize about becoming one with the Hashira himself. So many days Tanjiro spent daydreaming of becoming the alpha's bonded omega, to carry his pups and belong to him and him only.
So many thoughts, desires, memories.
And he can finally act out on them all. He can finally feel the unlocked fondness and yearning the Pillar has for him. It was so palpable he could taste everything.
It was strange to be in heat and coherent at the same time, to have that level of mindlessness yet maintain a state of awareness to where you know exactly what you want and how. “K-Knot! Please! Breed me a-alpha!”
Kyojuro’s hips faltered from the increasing swell at the base of his cock, a massive bulbous shape tapping on the outside of the omega’s pussy repeatedly as he essentially hooked his arms under their lower back and thrust with persistence. “Y-You want puppies? Huh?..” He huffed out and watched as Tanjiro perked up suddenly with a loud warbled cry— “Y-YES!” It was desperate and pleading. Much like the inconsistent moans falling from his mouth one after the other when Kyojuro picked up the pace.
Tanjiro's smaller body was easily manhandled into a mating-press position, his flexibility resulting in a much easier access as he was forced to watch the alpha's hard knot dip into his pocket of frothing slick.
It was such a lewd sight but he couldn't bring himself to look away, he could only stare absolutely shocked at how his tight cunt could take something so girthy. To him it was certainly enormous. Every throbbing vein glistened from the omega's personal fluids which further messed the bed from their extreme coupling.
When Kyojuro moved to lower himself to be face-to-face with the boy, Tanjiro wasted no time in wrapping his arms around the man once more to pull him ever closer. Unexperienced lips meshed with the Flame Hashira’s as that little body was ravaged, ruby eyes glassy with fat tears streaming down his cheeks. “A-Alph—” He tried to speak but it was oh so hard when Kyojuro slotted their mouths together again. His much larger tongue curling from his maw to lick into Tanjiro’s own.
The omega mewled, tasting the potent saccharine flavor of the alpha’s venom along those dangerously sharp teeth. He cared less if he scraped his tongue along them more than once.
“M-Mhhn! B-ite.. Bite me!”
Kyojuro pressed his face into the crook of the omega’s neck as they tilted their head to the side, ready, presenting and expecting a bonding mark. And yet he stalled, uncertain even through the intense moment of euphoria. He was still unsure if that was exactly what he should do.
Wouldn’t it be taking advantage of this young boy?
Wouldn’t it be unfair to him, would it not be wise to wait?
Surely it’s just their heat speaking to them, making them act out this way…
Lithe fingertips carded through unruly fiery locks at the back of his head, softly tracing the nape of his neck. He felt a pair of warm lips brush along his jawline up to his earlobe where the small omega whispered.
It was so sweet. Endearing. Patient.
“It’s okay. I trust you. I w-want you to.” Tanjiro tenderly cupped the alpha’s face with both hands now, making the grown man gaze down at him with his eyes blown wide in disbelief. Kyojuro overlooked that Tanjiro can scent emotions so easily as if it were displayed on a scroll directly in front of his vision.
Kyojuro’s own only wavered from withheld tears gathering along his lower eyelids, falling down the etched scar of his damaged eye and dampening the omega’s roughened yet warm palms. It was as if the sunlight itself embraced his soul with such serenity.
“T-Tan—”
Something within him coiled, constricting around his lungs like a binding serpent. He couldn’t breathe. This feeling wasn’t stress, it was without a doubt immeasurable passion finally showing its true colors. Spreading its wings inside of his chest and expanding past the ribcage. He wanted to stop these tears, but it was hopeless. He couldn’t cease the stammering inhale when Tanjiro brushed his thumbs along the alpha’s cheeks.
Those vibrant cherry eyes held nothing but a promise.
A promise of security.
For eternal affection.
For a family.
Kyojuro leaned into Tanjiro’s space and switched their position, allowing the boy’s legs to wrap around his waist and Tanjiro threaded their fingers together when the man above took hold.
There was no more fear, what did he have to be afraid of? There was nothing. He was free to delve into the surrounding pheromones of the omega below him that had the expression of someone so enraptured and entirely trusting in him. It made his chest ache. In such a pleasant way.
“Kyo-” Tanjiro’s words were cut short due to an abrupt kiss, the alpha melding their lips together for something much more passionate and less hurried. Something languid that he breathed his entire heart out into, and he was positive Tanjiro could feel every fraction.
Kyojuro's pace merely faltered once he picked up where he left off, securing himself to the hilt in consistent thrusts.
If the labored breathing from the man meant anything, it was that he too was teetering on the outskirts of his own orgasm. Never giving the chance for Tanjiro to forget what that imminent knot felt like kissing his outer lips and clit.
Every whimpering moan was muffled and drunk up by the alpha, his larger much more experienced tongue unfurling in the little one's mouth to taste him fully.
Tanjiro spread his legs open just a bit wider to compensate for the adult's form that ravaged his body, nails gauging deep red welts down the Hashira's back the moment that thick knot drove into his pussy past the outer rim.
“Mm-MMNHH!?” His brain felt lightweight from lack of oxygen since the two were continuing to forego any wellbeing of the outside world.
The room was doused in nothing but the raw scent of slick, sweat, musk and heady pheromones. Both alpha and omega fused in a blissful harmony of aromas with Tanjiro's sweet burnt wood, crackling open flame and woodsy pine that matched perfectly with Kyojuro's smoky raging fire with just the barest hint of oak and honey.
With the little omega secured Kyojuro was free to thrust into their pliant body as roughly as he wanted, carving his cock through those sloppy walls as he neared his peak.
Dagger-like fangs protruded within his mouth, venom idly dripping past his chin as he fucked into that succulent heat. Savoring every keening yelp and weeping moan from the boy who gripped him like a vice. Squeezing around the very same massive cock that swelled his toned stomach from the alpha’s hearty size difference.
It was a blessing Tanjiro felt little pain with the intrusion, being that he was stretched so deliciously it brought heavy tears to his eyes when he threw his head back with an echoing scream; legs locking around Kyojuro’s waist when the man shoved himself inside for good. Knot swelling twice its size to accommodate the flood of viscous cum planting itself within the young omega’s fertile core.
The hardness of the knot pressed directly against his erogenous zone, milking him through another plummeting climax and yet.. This one felt so severe. So intense. Feeling as if magma ran through his veins with the voltage of extreme sensuality.
It was when he realized while he was hoarsely sobbing, that he felt it.
The puncture of sharp teeth into the side of his neck. Directly at his bonding site where he was being injected with the binding toxin from Kyojuro’s canines.
His legs wouldn’t stop shaking, it felt as if this peak of delight was everlasting as he feebly clawed his nails along the already scratched-up back of the Hashira. Every nerve was set off like a crackling surge. Akin to a firework that ached to combust but was unable to do so. Only capable of swelling and growing with heat comparable to a rapidly bubbling cauldron of liquid yet to spill over.
If he listened close enough he could hear the predatory snarl from the man as he was pinned to the bed, being stuffed with his semen and marked all in the same breath of his syrupy summit, the bedspread beneath them was so wet by this point and he could even hear himself spurt against the alpha.
His own fluids merely soaked onto the man’s thick tuft of blonde pubic hair that pressed against his pulsating clit.
“A-Aah!— Alph-“ He could barely swallow around the saliva that pooled in his mouth, quivering as Kyojuro laved his textured tongue along the bitemark to seal the bond. Coagulating the blood and scenting him all the while.
Nothing could conquer the rumbling purr of satisfaction that came from the Pillar when he finally had his wish granted to bond with the omega. To mark him. Breed that bountiful body with his seed.
A higher part of his mind hoped that his seed would take, and the young boy would be pupped thoroughly.
“Kyo…” Tanjiro’s voice was so soft, timidly expressing his fatigue with those half-lidded gleaming eyes of sanguine jewels. His gaze gave away the sincere quantity of love he held for the man that made eye contact with him. Watching as the alpha reacted pleasantly to the charming smitten smile Tanjiro gave.
This wave of his heat was far from over.
“Thank you..”
Tanjiro stirred when sunlight flickered through the drapes partially covering the room’s window, it brought a sensation of warmth across his damp skin.
It was muggy and a tad uncomfortable even with the blanket being halfway off his body and bunching at the dip of his waist. Yet throughout this minor discomfort came a vast waft of comfort. A puff of warm breath tickled the nape of his sore neck and nestled there, breathing softly, was Kyojuro.
The alpha had his arms firmly wrapped around the boy’s body and held him close to his subtly rising chest. He seemed to be in a deep cycle of slumber, nothing but the scent of protection and commitment emitted from his being.
Tanjiro couldn’t help but huff fondly and his cheeks flushed a vibrant scarlet in thought of the things they did only a few hours ago.
He lost count of how many times the alpha had him moaning and begging on his lap, stomach, back or bent every which way possible to take the feverish penetration in such a brutal manner.
The proof was the amount of bruising that blemished his hips, waist, thighs, and wrists.
Love bites littered his body from his neck all the way down to his thighs and parts of his torso had rings of pink and reddish-purple from how frequently the alpha sucked on his sensitive chest.
It was just what he wanted, he didn’t want to be treated like some delicate flower that would break easily. He knows his strengths and limitations. He wanted this. He wanted to be handled roughly by the Pillar, to be shown nothing but that insatiable hunger. To see just how fast he could push the alpha to his breaking point.
— And it worked, apparent with the now permanent marking on his neck that united them together for life.
There was a gruff chuckle that vibrated against his back and had him shivering lightly, large palms tracing the distended mound along the omega’s stomach as the very same alpha he deeply worshipped had his knot embedded deep in his tender pussy.
“I can practically hear your thoughts now, you know.” Kyojuro rumbled, brushing his lips along the mark on the side of the omega’s neck, enjoying the shuddering whine it earned him. The area would be sensitive like no other for the longest. He couldn’t be a happier man.
Despite the joy and afterglow of their frequent coupling, it felt as if something was incomplete.
Here they reside in a very bare futon that he had to strip the drenched sheets from, huddled close to the young boy he spent countless hours thinking about— And yet he felt a missing piece.
“Good morning, Kyo—"
“Marry me, my boy!” Kyojuro’s booming voice suddenly startled Tanjiro from the laxed state, his eyes widening quickly. “Wh-What!?”
Kyojuro sat up just enough to stare down at the omega, careful not to tug on their secured tie. “I said marry me, Tanjiro.” Owlishly wide flaming eyes pierced through the boy’s very soul, it was less intimidating and more surprising.
“N-No I… I heard you but.. Are you sure you want to?” Kyojuro clearly felt the twinge of anxiety rippling through the young man’s consciousness, he looked so.. Afraid. Their bonding amplified every emotion tenfold, every sensation be it physical or mental.
“I have never been more certain my entire life, if I may be honest with you I-.. I thought of courting you the second time we met on that train. Sensing your unstoppable strength, longing for rightness and kind familial love for your sister. The same.. The same little girl I foolishly wished death upon.”
Kyojuro’s palms cupped the boy’s face, thumbs tenderly brushing along the apples of his cheeks. Staring deep into those glittering wine-red eyes. “With all my heart and very soul, Tanjiro.. I once again request your hand in marriage. If you will have me. I assure you I will protect you until my very dying breath.”
Kyojuro sounded anything but desperate, his voice expressed confidence and a strong promise of every word spoken. Tanjiro just stared, eyes wide in shock as his thoughts processed slowly.
He gave the alpha a smile with quivering lips and an even shakier voice, “Y-Yes! I—” He found his space invaded by a happy man with his mouth pressed firmly to the young boy’s own. Tanjiro inhaled sharply, wrapping his arms around Kyojuro’s shoulders, small tongue seeking entrance into the older male’s mouth and was welcomed with acceptance.
The bonded couple laid there in the silent room, ignoring the daily bustling activity throughout the Butterfly Estate, treasuring the time together in peacefulness. Sharing a kiss so passionate and genuine, it had them both tearing up over.
“I’m glad, my boy!” Kyojuro exclaimed albeit laughing at the fact that he was wiping the tears from his eyes with the back of his palm, giving a lopsided grin. “Look at me, now I am the one severely emotional all over again!”
Tanjiro couldn’t withhold the giggle that erupted from his mouth, his hands softly squishing Kyojuro’s cheeks and bringing their noses together. “You’re so unique, Kyojuro… I’m blessed that you were my first and that you wish to wed me. Thank you, for everything.”
Kyojuro barely blinked, undamaged pupil widening from his fondness alone, corners of his lips quivering into a wide smile that creased his eyes. All the while Tanjiro caressed his fingers along the alpha’s face. Tracing his most recent wound.
Unable to fully heal yet in its own way it was undoubtedly gorgeous on him, despite the cloudy eye. It was fitting for a man so formidable and supreme to survive the harshest of injuries.
“You are such a blessing, Kyojuro…”
It was safe to say that after two and a half days of nothing but sex, Tanjiro was severely fatigued and low on energy by the time his heat passed.
Kyojuro looked to rarely have lost any stamina, the only thing he came out of the room shouldering was the excessive claw marks all along his back, arms and the little teeth rings dotting his chest and neck. Of course the majority of their loving wounds were covered by their yukatas— Besides the bond bite Tanjiro cherished to show off.
Breakfast was inevitably awkward, the two sitting side by side as they completely demolished several servings of food and water to replenish their sapped vigor.
All the while Inosuke who sat in front of them suddenly jolted upright, no longer looking confused as he did for the past few minutes of peering between Tanjiro and Kyojuro.
“Ah! I knew it!”
Tanjiro, Kyojuro, Zenitsu and a few of the estate’s inhabitants looked over to the wild-child who was now standing up on his seat; pointing at the Pillar and his mate.
“Sit down you idiot! It’s too early for your foolishness!” Zenitsu barked up at him, attempting to yank at his leg.
It was pointless because whatever Inosuke had on his mind, he spoke without hesitation. Not even sugar-coating it to spare everyone the second-handed embarrassment.
“You guys did breed like animals! I knew I sensed something going on!”
The reaction was instant with an astonished gasp from others, Tanjiro gagging on his rice and Kyojuro stiffening with a gaze so wide it was a miracle his eyes didn’t fall from his skull.
Yes, it was obvious with the mark on the young omega’s neck and the healthy glow of his skin. Not to mention their closeness since this morning but— Did Inosuke have to bring it to everyone’s attention?!
It wasn’t even warranted.
At all.
As per usual…
“I-INOSUKE!” Tanjiro’s voice was high and squeaky, his appearance burning as hot as the very coals he used to tend to, hands slapping to his face to shield himself. Yet it did very little to hide that the omega’s blush reached his ears as well.
Kyojuro just bellowed out a fit of laughter at such early morning shenanigans. Made even more hilarious by the horrified and or irritated expression on Zenitsu’s face as he tried so hard to tune out everything.
Hearing that his best friend had found a mate before he did was one thing but concluding that they did in fact bed together was something else entirely!
“Indeed, quite a good morning to you too boar-headed boy!”
