Uzui Tengen: Former Sound Hashira

“Move your asses! If you don’t finish the last rep, no dinner for you tonight!”

Your husband’s loud voice carries a great distance, no surprise coming from the former sound hashira. This allows you to find him and your other co-wives fairly easily as you make your way up the mountain side where Tengen’s endurance camp had been set up.

You’re met with a somewhat…comedic(?) sight..of your flashy husband dressed in a casual kimono swinging a wooden sword at the fallen demon slayers who were clearly on the verge of passing out from exhaustion. You couldn’t help but feel pity for the poor kids.

“If you don’t get it together you’ll never survive what the other hashira have in store,” Tengen huffed, seemingly more annoyed than angry.

“Now now, Tengen-sama, don’t be so hard on the kids,” you sigh, setting down the extra pot you had been tasked with bringing to help prepare dinner. “You’ll end up giving them all nightmares.”

The way Tengen’s face lights up when he sees you makes your heart flutter. "Y/n! I was wondering where you went off to."

"I asked her to go back home to grab another stew pot," Makio chimed in, all while throwing a subtle glare towards a Suma. "Since someone forgot to do what they were told and bring it like asked.

Suma proceeds to hide behind you and Hinatsuru as you help her with the rice for the onigiri. "Uwahh! Y/n-san! Hinatsuru-san! Makio-san is targeting me again!"

"Please, don't start," You sigh.

"We all need to do our part," Hinatsuru said, like the mature woman of the group she was. "Let's do our best with dinner so that we aren't inconveniencing Tengen-sama."

With four sets of hands, you guys get dinner done by sundown, the smell of fresh onigiri and beef stew wafting through the air. However, the poor demon slayers were so worn out from your husband's brutal training, you don't think any of them would have the energy to even think about eating. Still, Tengen snaps at them to do so as to not let you all's hard work go to waste.

"Tengen-sama, please try to relax a little," you gently say, tugging on the end of his kimono. You offer him a bowl you had prepared. "It's not good to get so worked up."

Although grateful, Tengen doesn't say anything as he takes the food you offered, sipping the broth in silence.

That night, you soak in the Uzui Manner's private onsen, the stress of the day clouding your thoughts. You’re worried. You know the final battle against Muzan will inevitably happen, but you’re terrified. For your friends. For your family. What if Tengen has to come out of retirement to help? What if you and your co-wives are caught in the middle like in the Red Light District?

You’re so in your head that you don’t even hear the door open and someone enter. “What a surprise. I thought you were in bed by now.”

Tengen’s voice startles you and you’re quick to sink into the water to cover yourself. Your husband’s laughter fills your ears. “What are you being shy for?” Clad in nothing but a towel, you gawk at your husband’s physique. Despite officially retiring from the Demon Slayer Corps, his consistent training kept him in shape.

“You just surprised me…that’s all…”

Tengen settles behind you in the bath, the water sloshing as he enters and pulls you into his lap. You relax against his chest. “You wanna tell me what you were thinking about?” He asks, tracing his hand down your side making you shiver involuntarily.

“N-no….its nothing. But you seemed stressed earlier, Tengen-sama. Is there anything I can do for you.”

Tengen sighs, leaning back against the edge of the bath, arms spread and muscles tense. “It’s nothing, love, don’t worry.”

You frown. You then turn so that you’re straddling Tengen’s lap, the water splashing with your movement. Tengen raises a brow in confusion, but doesn’t question your actions. “P-please allow me to help you, Tengen-sama.”

Tengen chuckles, cupping your cheek gently. “You already do more than enough for me, and for that I’m very grateful.” The kiss he pressed against your lips starts off soft, only to grow more intense and desperate. You squirm, letting out a small whimper.

Feeling you rock against him, Tengen groans, his cock beginning to harden. He scoops you up underneath your thighs with one hand, not breaking your kiss. As he lays you down on the onsen deck, you shiver at the cold feeling of the stone. Tengen trails gentle kisses down your neck while his fingers grace your clit, stimulating the sensitive nerves.

“W-wait. W-wait,” you suddenly protest. Tengen pulls back, worried he hurt you. “I-I want to be of use to you, Tengen-sama. Please let me please you.”

Tengen wears a rather perplexed expression before chuckling. He sits back on the end of the bath. “Ok then, please me.”

You drop to your knees before your husband, taking his cock gently into your hands. It’s already stiff with arousal, pre pearling at the fat tip. Your finger traces the thick vein running up the side of Tengen’s length, making him twitch.

Tengen groaned as your warm mouth enveloped him, his head leaning back in satisfaction as his fingers gripped your hair tightly. You immediately began to suck, feeling your jaw strain as he began to swell in size. Tears prickled in your eyes, and you rest your hands on Tengen’s thighs to steady yourself.

"Mhmm fuck," Tengen moaned deeply. His low raspy voice only turned you on more. He gripped Your hair harsher and pulled you closer; you nearly gag. "Fuck. Don't stop. Use your hand. Fuck. There you go.”

You eagerly obliged, sucking him harder and taking more of him, or as much as you could cause he was just so damn big. Tears trickle down your cheeks, and it takes all Tengen’s willpower to not buck into your mouth. The sight of you looking at him so innocently, crying as you try to take his size almost has him coming down your throat. You can tell he’s close to his release from the way he tenses, muscles tightening, yet he quickly pulled you away.

“T-Tengen-sama?” You question, out of breath. Before you can react, Tengen has you pulled into his lap and your knees pressed to your chest with his arms wrapped under your legs in a rather embarrassing position that has your cunt exposed. In a single thrust, the tip of his cock kisses your cervix and you’re crying out.

Tengen rests his head against your back, breathing heavily. “You’re so good to me.” He groans at the feeling of your warm cunt wrapping snuggly around him. “I love you so much.” Tengen’s grip tightens, pulling your legs back further as his hips buck up, stretching you further. The slightly uncomfortable position makes you whimper.

“But tonight, I’m going to fuck you like I don’t.”

Iguro Obanai: Serpent Hashira

You know how ruthless and impatient your husband can be, so you pity the poor slayers who were stuck in the vicious vice-like hold Obanai’s training has. Most of them had been there for at least a week, if not more, unable to perform at a level that satisfied your husband. So, you’ve taken on somewhat of a nurse role, providing first aid to the many bruises, welts and rope burns the slayers received as part of the training. Your hope was that your treatment would lessen the pain of entering the baths.

“There! All done,” you say, closing up your first aid kit having just treated the cut on one member’s face. “Next time, remember to guard your vital spots. You’re lucky it was only training. A demon wouldn’t be so forgiving.”

“R-right! T-thank you Mrs. Iguro!”

You wave the slayer off as you finish packing your things up. Though you try to ignore it, you can still hear the whispering about your husband.

“How did such a sweet woman end up with a man like the serpent hashira?”

“Yeah the only real demon here is him…”

You grit your teeth in annoyance, prepared to say something when the sliding doors slam open. The atmosphere tenses as your husband walks in, a very angry and intense aura surrounding him.

“If you have time for idle chatter then you must not have worked hard enough,” Obanai scowled, Kaburamaru hissing around his neck. The slayers all quickly scramble to their feet and ran to grab their swords and avoid Obanai’s wrath.

You tug on his haori, stopping him from moving. “Dear, be nice.”

The scowl on his face somewhat softens only to immediately return when a new person announces their presence: Kamado Tanjiro.

“I look forward to training under you,” Tanjiro says, as cheerful as ever. Either he didn’t see your husband’s murderous look or he didn’t care. “Ah! Hello to you too Mrs. Y/n!”

You return the bright smile with one of your own. “It’s great to see that you’ve recovered well, Kamado-kun.”

“Oí! Don’t be so casual with my wife like you’re friends!” Obanai snapped. “And the rest of you stop gawking at her!”

You can only sigh. Of course, anything that you said practically went in one ear and out the other, and Obanai was so rough with the trainees you were surprised he didn’t break anything. Poor Tanjiro in particular seemed to get the brunt of your husband’s annoyance, leaving him with thankfully only some bruising since the training was conducted with practice swords instead of real blades. However, Obanai wouldn’t let treat anyone’s wounds this time around. The moment he ordered for them to scram somewhere, he dragged you out the dojo and back to the main house.

His grip on your wrist was tight, and you knew better than to protest when he was in his foul moods. But the fact that he hadn’t uttered a single word was making you somewhat anxious for what was to come. Was he somehow pissed off at you too?

Once you make it to your shared room and Kaburamaru slithers off somewhere, Obanai closes the sliding door. It’s just the two of you, the tension in the air is suffocating.

“U-um…O-Obanai…a-are you mad?” you try to break the silence only to receive the most piercing glare from your husband’s dual colored eyes, making you hush up instantly.

“Mad?” Obanai scoffs. “Nothing you do can make me mad at you. But…” His eyes trained to yours as he backs you into your shared futon. “I hate the way those idiots gawk and act too friendly with you. You’re my wife. You’re mine and mine alone.”

Obanai grabs your chin roughly, forcing you to look at him. His intense gaze while nerve racking is so insanely attractive that you’re whimpering quietly, trying to rub your thighs together in desperate need. Obanai picks up on this and lets out a low chuckle.

“I guess I have to remind you in other ways that you belong to me. Clothes. Off.”

You quickly start taking your kimono off, untying the Obi sash. Clearly you don’t move fast enough for your husband’s liking as he flips you on to your back and starts pulling the fabric off of you.

“W-wait, O-Obanai!” Your cheeks flush in embarrassment. Obanai ignores your pleas, and proceeds to use your obi to intricately tie up your l your wrists behind your back, pinning your arms almost uncomfortably together.

“Don’t you look pretty,” Obanai hums in amusement, pleased with the way the bindings were. He grabs your wrists and forces you to bend over, ass in the air. Obanai nudges your legs up to have a clear view of your dripping cunt, to which he inserts a finger, then two. You helplessly squirm against the restraints, keening against his touch.

“You’re so greedy,” Obanai scoffs. “You’re just sucking my fingers in.”

“Please, Obanai,” you beg. “I need you inside me.”

“Hm…since you asked so nicely.”

You hear him shuffle around, presumably to remove his clothes. You then feel the heat of his chest as he leans over you. Although he was somewhat rough with the restraints, Obanai is tender when he kisses your shoulder blade.

With one hand on you waist and the other on your wrists, Obanai inches his cock into you, groaning at how tight you feel around him. He bottoms out easily and you moan at the uncomfortable arch the position puts you in.

“M-move…p-please…” you whimper.

Obanai chuckles. He pulls out just to the tip before thrusting back in, setting a rough yet steady pace. His cock reaches so deep thanks to the position he has you in, making you gasp each time it kisses your cervix.

“Fuck…you feel so good…” Obanai groans. Usually he’s not one to be overly vocal during sex, but the heat of your cunt was just so addicting and he thought he would lose his mind.

“P-please…” you stumble over your words as he pounds into you. “C-can I hold you?”

Obanai falters briefly, his chest feeling strangely full. How do you always find a way to be so sweet to him? You were going to be the death of him.

Nonetheless, he unties the knot to release your wrists. He flips you over, realigning his throbbing cock at your entrance. You immediately wrap your arms around his neck and legs around his waist to pull him close. Both of you let out shaky moans as he thrusts back in. You gently kiss at the scars on his mouth, and he shivers in response, taking one of your hands to intertwine with his.

“I love you,” he mutters so quietly you almost don’t catch it. You nuzzle into his touch.

“I love you too.”

Shinazugawa Sanemi: Wind Hashira

You’re currently pissed at your husband and ignoring him. You ignoring him has him even more pissed off, so the Shinazugawa mansion is tense and a literal war zone. The impending war against Muzan is inevitable. While you understand that, you see no reason why your husband has to be such a dick to everyone. Especially to his own younger brother.

“That damn bastard, who does he think he is, going off the rails like that,” you angrily mutter under your breath as you threat Genya’s injuries. He winced at the antiseptic on his cut. You frown. “Sorry sweetheart…”

“It’s ok…Y/n-nee…” Genya says half heartedly. The recent fight between the Shinazugawa brothers ended up escalating to a dangerous point. If it weren’t for Tanjiro’s interference, there probably would’ve been more injuries. And having known the Shinazugawa brothers since childhood, you were fiercely protective of Genya. So seeing Sanemi attack his brother the way he did without any hesitation was literally your last straw.

“I’m sorry…” Genya said.

“Hm? For what?”

“For causing trouble in you and nii-san’s marriage…” the younger boy avoids looking you in the eye. “if only I could use breathing techniques and weren’t so weak…then maybe he’d acknowledge me.”

“Awe, Gen, don’t say that,” you say, pulling the younger boy into a tight hug against your chest. “Your actions have nothing to do with my marriage. Your brother is just being a pain in the ass but that doesn’t mean I still don’t love him. I know he has a shitty way of showing it, but he does care. I’m sorry that you’ve somehow gotten in the middle of our marital problems. I promise things will get better. For all of us.”

You finish tending to his injuries before placing a tender kiss on his forehead, like you used to do when you were kids. Still, Genya’s face explodes red at your babying, making you laugh as you take your exit. As you leave, you’re surprised to see your husband standing outside the door with his arms crossed. Your face sours.

“The fuck you want?” You snap.

“Still got a fuckin attitude?” He retorts.

“Says you.” You walk off in a huff. Sanemi sighs and runs after you.

“Y/n, wait. Please talk to me.”

“About what?” You say bitterly. “I don’t got shit to say to you after the stunt you pulled. I don’t want to hear anything from you unless it’s an apology.”

“Fuck, fine I’m sorry! Now will you listen to me?!” Sanemi desperately said, grabbing a hold of your wrist to stop you. Your eyes narrow, not trusting his words. “Look. I know I was wrong but I can’t take anymore of you ignoring me and doting all over Genya.”

You snatch your hand away, scowling. “So now you’re jealous of your kid brother? I used to change his goddamn diapers.”

“That’s not…ugh fuck. Come with me!” Once more Sanemi grabs your arm, dragging you through the manner against your protests. He brings you to your shared room, which for the past few weeks you’ve stopped sleeping in out of spite. Sanemi closes the door, locking it shut.

“Now what? You got me alone.” You scoff.

“Ugh just shut up!” Sanemi yells, grabbing your chin and kissing you frantically, almost desperately. Your response is muffled and your knees immediately go weak as he forces his tongue in your mouth to deepen the kiss. You’re gasping for air by the time Sanemi pulls away. He buries his head into your shoulder, inhaling your scent that he’s missed so much.

“I’m sorry…dammit…” Sanemi’s voice cracks slightly. “I don’t want to lose you too. I couldn’t bear losing another person so important to me…so please, stop being mad at me…I’m sorry.”

“Nemi…” You cup his cheek before pinching it harshly making him hiss. “You dumbass. That’s what this was all about?I didn’t realize you were this goddamn emotionally constipated.” You sigh, Sanemi now glaring at you while rubbing his cheek. You gently kiss the tip of his nose. “I’m not going anywhere any time soon, okay? I promise.”

Sanemi exhales, almost like a sigh of relief. “Okay.” He kisses you again, this time gentler as if he’s afraid you’ll leave. You wrap your arms around his neck, pulling him deeper. “I’ve missed you.” Sanemi muttered. His hands begin to wander, trailing up the side of your waist under your uniform.

“Did you miss me, or my body?” You tease.

“Mhm? Both.”

“You’re such a tease.”

“Yet you love me anyway.”

Sanemi kisses you again with more force, all while guiding you down to your shared futon. His hands are rough, groping your breasts, pinching your nipples that stiffen at his touch. You roll your hips upward to press against the growing bulge in his pants. Sanemi groans, biting your lip.

“You like testin’ my patience, don’t you?” Sanemi huffs.

“That depends,” you taunt, beginning to unbutton your uniform top. Sanemi swallows thickly, his Adam’s apple bobbing. “You gonna do something about it?”

Sanemi grit his teeth. He grabbed you by the waist, flipping you on your backside, the rest of your clothes torn off from his own impatience. “It looks like I’ll just have to fuck the attitude out of you.”

Your husband makes do of his promise, fucking you senseless into the sheets, weeks of built up tension between the two of you finally being released. He’s aggressive and rough, gripping at your hips so tightly they’d probably bruise. Your neck is littered with bite marks, while Sanemi’s already scared torso has fresh red scratches from the way you grabbed at him. Not that he minded.

“F-fuck,” Sanemi groaned, relishing the way you clenched around his cock. His hips snapped against yours, making you gasp and shudder. “Fuck I missed this. I missed you. Don’t ever fucking ignore me again.”

“N-Nemi, please, I’m close,” you whimper.

Sanemi grins. He puts your legs over his shoulder, pressing down to pin your thighs back in a mating press. The position, though uncomfortable, allows for his cock to reach even deeper. You feel so deliciously full, Tears prickling in your eyes. you cover your mouth trying to hide the sultry moans leaving your lips.

“Nope, I need to hear you,” Sanemi pants, pulling your hair. Your cries are music to his ears. “I need everyone to know how good I fuck my beautiful wife.”

He uses the pad of his thumb to wipe away your stray tears before kissing you tenderly. His pace faltered just a bit, making his thrusts more sloppy as his low grunts turned into airy moans. "Ah fuck I'm gonna come."

Sanemi gave one last deep thrust that had you gasping for air. You shivered feeling yourself be filled while your own orgasm hit. After he was sure he finished, Sanemi pulled out and sat back on his heels. He stared down you with a satisfied look on his face as some of his seed leaked from your swollen sex.

He scooped up some that spilled on to the bed and shoved it back into you. You whimpered from the overstimulation. "N-no more."

"Don't tell me what to do," Sanemi huffed. He aligned his cock at your entrance again and sank in with ease. He lets out a satisfied sigh and pulls you to his chest. "There. Now it'll stay in."

Tomioka Giyu: Water Hashira

“Tomioka-San? Hello! Tomioka-San? Excuse me? Are you there? Sorry to bother you. It’s Kamado Tanjiro!”

It’s the third day in a row the young boy has come by. At this point, you find it quite comical but you can tell your husband is losing his patience.

“Just entertain him, dear,” you say, folding up the laundry. “You know he’s not going to stop until you answer.”

Giyu doesn’t say anything before picking up his katana and leaving the room. You sigh. He had been so distant since the hashira training started. For some reason, he opted not to participate, and you could only assume that’s why Tanjiro’s been by every day to convince him otherwise. Nothing you could say would really change his mind either. The last few nights Giyu had been staying out later, only returning when he knew you’d fallen asleep and leaving first thing in the morning.

You didn’t want to push and pry, but you hope he’d open up soon. Or maybe, hopefully Tanjiro could talk some sense into him. You decide to at least go to the door and greet the boy.

“Giyu-San!? Maybe he’s not home…”

“He just left, in fact,” you say, opening the door. “Maybe you can catch him for me.”

“Ah! Y/n-san! H-hello! Sorry if I disturbed you!” Tanjiro said with a bow.

“No not at all! You’re always welcome here.” You then sigh. “Sorry my stubborn husband is causing you such trouble. If it’s not too much to ask, please talk some sense into him. I’m sure whatever it is it’s important.

Tanjiro smiled. “Of course! Leave it to me!”

For the next five days, Tanjiro shows up, trying to get your husband to talk to him. You’re thoroughly entertained by the situation that you do little to mitigate, ignoring Giyu’s obvious and desperate looks for help. After almost two weeks of this, Giyu finally comes home early one night with a rather defeated expression. You’re in bed reading when he enters your shared room and immediately collapses on the futon.

“Rough day?” You tease.

“Tanjiro doesn’t know when to quit,” Giyu sighs. He sheds his haori and places his is katana off to the side. “He wanted to have a soba eating contest?”

You laugh. “Did you win?”

“No. I yielded and promised to help with the hashira training.” Giyu doesn’t seem to thrilled by it from the tone of his voice. You frown, close your book and motion for your husband closer. Like a child, he crawls into your lap, laying his head against your chest and wrapping his arms around your waist. Giyu sighs contently, inhaling your scent.

“Why were you so against participating in the first place? I’m sorry, but I’m having trouble understanding,” you say, gently running your fingers through his long hair, pulling it out of his usual ponytail.

“Can we talk about it later?” Giyu mumbles. He nuzzles his face into your chest. “I just wanna hold you right now.”

You cup Giyu’s cheeks, forcing him to look at you. You smile. “It’s ok. I’m here for you.” You kiss him gently. Giyu relaxes into the kiss, groaning at the softness of your lips. “I love you so much. Don’t forget, okay?”

Giyu exhales. “Okay.”

He kisses you again, this time with more urgency. You wrap your arms around his neck to pull him close as you lay back down into the futon. Giyu trails kisses down the side of your neck, leaving love bites in their wake. His wandering hands tug at your nightgown, exposing your breasts to the cool air. His hair tickles your cheek making you giggle.

“Come on,” you tease, unbuttoning the top of Giyu’s uniform. “Clothes off.” His cheeks were flushed red, and his arousal was evident from the growing bulge in his pants.

“Help me, will you?” Giyu asks, shyly hiding his face in the crook of your neck. He watches while you unbuckle his belt and losen his trousers so that they fall to the floor. He could almost sigh from the instant relief when you release his erection from the confines of his boxers.

You give his cock a few languid strokes, making Giyu shudder in response. He twitched in your hand as you rub your thumb over the sensitive tip, precum beginning to leak out.

“A-ah…f-feels good…” Giyu groans. He has to steady himself on his elbows, resting his forehead against yours. It takes all his strength not to cum right there on the spot. He hikes your leg up around his waist and aligns his cock at your dripping entrance. “Relax, okay? I got you.”

Giyu slowly thrusts in, your wetness causing little resistance. You both groan at the feeling of him stretching you out. Your hips buck upwards, searching for more.

“G-Giyu, m-more,” you plea.

Your husband grunted and picked up the pace. He couldn't get the enough of the way you felt around him. The way your gummy walls would convulse with each snap of his hips. Your high pitched and needy moans for him and him alone nearly drove him over the edge.

"T-there! A-again!" You beg. You wrap your arms around Giyu’s shoulders to hold him close. Capturing your lips again, Giyu sucked hard on them in order to bruise. His thumb jabbed against your clit.

The action caused You to cum. You squealed, biting down on his tongue, making him growl. Your clit pulsated, feeling like it was still vibrating. Tingles raced through veins, rocking your entire body.

"F-fuck, I'm close!" Giyu pants.

His own high was reaching. His thrusts became less rhythmic and more sloppy. Low grunts and moans left his lips. The feeling of You tightening around his dick even more was enough to send him over the edge.

He comes with a low groan. His body rocks and he collapses on top of you, burrying his head into the crook of your neck once more. You squirm feeling him release into your womb.

Giyu pulls out, almost reluctantly and pulls you into his chest. He holds you close as you lull off to sleep. Before you doze off you hear your husband mutter a soft “I love you.”

Himejima Gyomei: Stone Hashira

“Damn it!” You huff. “Why…huff…did his…huff…training…huff…have to be on top of a stupid mountain!”

You slowly waddle your way up the top of the mountain side, on your way to deliver lunch to your husband who had been preoccupied for weeks with the Hashira training. He barely had been home. If he was, it was usually long after you had gone to sleep just to check on you and your unborn child. Then, he was gone before dawn to resume the training.

You missed him dearly. You hated how empty and cold your futon felt without his warmth. You hated how antsy you felt with not only the fear of the upcoming battle with Muzan looming in the distance, but the anxiety knowing that your due date was approaching within the next month. Sitting around was driving you crazy, so you took it upon yourself to make your husband a home cooked meal and bring it to him, asking the crow to guide you. What you didn’t expect was him to be at the top of a literal fucking mountain.

“Ugh I can’t do this…” you groaned, pausing at a random tree to rest. “My feet are cramping and if this child kicks me in my bladder one more time…”

“Eh? Mrs. Himejima?”

“Eh? Ah! Genya!” While you’re thrilled to see the boy that you’ve quite honestly grown attached to like your own child, he on the other hand is freaking out. Why were you out here alone in your condition? Did Himejima know that you were here? What should he do? Help you get home?

“Genya, have you seen Gyomei?” You eagerly ask, grabbing the boy’s hands. “I was trying to surprise him with lunch, but I kinda got lost on my way up here. It’s such a ways away from the other hashira isn’t it.”

“U-um I-I,” Genya stammered. He then sighed. He couldn’t say no to you when your expression was so innocent. He also wouldn’t forgive himself he let you get hurt. “Ok. I’ll lead the way. P-please be careful. Let me know immediately if you need anything!”

“Of course!”

You follow Genya down a path, asking the boy how his training has been with the other hashira. Eventually, the sound of roaring water fills your ears and you both arrive to a massive water fall.

“Namu Amida Butsu,” someone chants and you realize that there are demon slayers standing under the water, bracing the impact.

“Oh my, this is Gyomei’s training?” You gasp.

“Only the first part,” Genya sighs. “Most people collapse and don’t get past the rest.”

“I see.” You’re not that surprised that your husband’s session was the seemingly most physically challenging and demanding. It would of course be no issue for him as his giant stature and inhuman strength made even the most impossible of tasks look like a breeze. But you feel for the younger ones who haven’t quite figured out how to unlock that same inner strength.

“Eh? Wait? Is that Zenitsu!?” You exclaimed, realizing you recognized a head of yellow hair floating down the river. “Ehh! Oh dear! Zenitsu!”

“Wait! Mrs. Himejima!”

You’re already waddling toward the riverbed, trying to reach out and grab the seemingly unconscious boy. You strain as you try your best to grab him, but he slips past you. The rocks are slick with water and before you realize it, you lose your balance. Before you tumble forward, someone grabs you by your waist and gently lifts you out of the river.

“My love, what ever are you doing here?” The low, calm rumble of your husband’s voice fills your ears. Your cheeks warm as your face lights up in excitement.

“Gyomei!” You turn in his arms to hug him around his neck. “I missed you! I bought you lunch! Come on, let’s eat it before it gets cold.”

Gyomei chuckles. “Let’s get you out of the wet clothes first so you do not catch a cold.” He looks over to Genya and gives a slight nod. “Thank you for looking after her. You can be done for the day, Genya.”

“R-right! Thank you, sensei.”

You talk your husband’s ear off about nonsense, him listening with a smile on his face as he carries your back home. By the time you make it back though, you’re sneezing, shivering slightly from the cold.

“My love, what ever were you doing up there?” Gyomei asks, setting you down. He gently unties your Obi, sliding the wet kimono off your shoulders. “You could’ve been hurt, dear.”

“I wanted to surprise you with lunch…” you say somewhat bash fully. “I haven’t seen you much and I’ve really missed you.”

Gyomei softly smiles. “I’m sorry. I didn’t mean to make you feel neglected.” He unties the juban undergarment and you’re left completely bare and exposed before him.

You feel slightly self conscious. Your body has changed so much from the pregnancy. Your breasts were constantly swollen and tender. Your stomach now round and full with stretch marks streaking across your thighs. Yet, Gyomei’s hands are gentle as he explores the new changes to your body. His fingers grace over the curve of your belly, smiling as he feels his baby…your baby…kick against his palm.

“It’s ok…” you let out a shaky breath. “I know it’s your job.”

“No, my first priority is you and will always be you,” Gyomei insists.

“M-mei, can you touch me?” You plea.

“But you’re so far along now. I do not wish to hurt you, my love.”

“You won’t!” Maybe it’s the pregnancy hormones. Or maybe it’s the fact that you’ve been missing the gentle intimacy with your husband due to his busy schedule. Either way, you’re finding yourself overcome with desire, wanting nothing but for Gyomei to take and fill you up. “Please?”

Gyomei sighs. He can’t say no to you. “If I hurt you at any point please let me know.”

Laying down, Gyomei pulls you by your waist over his face, his hot breath tickling your core. Your face flushes. “W-wait, Mei, I’ve gained so much weight cause of the pregnancy. I’m so much heavier now and-“

“I don’t care,” Gyomei says, his gentle hands caressing your skin. “You can sit.”

“B-but-“

“Sit.”

The command leaves your legs weak and you settle down over your husband’s face. He grips your waist as he begins to eat you out. You gasp, for some reason more overly sensitive than usual.

“M-Mei-“ you whimper. You rock your hips in tangent with his tongue. Gyomei’s touch tickles your skin. He traces the curve of your stomach, making you shiver. He cups your breasts. They feel larger, and more swollen than usual in preparation to breastfeed. Your nipples are more sensitive too, stiff from Gyomei playing with them.

Your thighs try to clench shut, which Gyomei puts an immediate stop to. He forces your legs open wider to have deeper access to your dripping cunt as he greedily laps up everything you drop. Your essence is so sweet and he can never get enough of you.

As much as he hates to admit it, he’s hated how much his responsibilities as hashira have taken his focus away from you. He’s missed your touch, your taste. He’s missed your scent and your presence. He has noticed all the subtle ways your body has changed and he hates that he hasn’t been around more often to witness it.

“A-ah, I’m gonna cum,” you whimper, gripping at Gyomei’s hair. You let out a soft cry as your orgasm hits. Your body shudders and you feel your clit tingle as Gyomei sucks on the sensitive nerves. He laps up your release, squeezing your hips to ground himself. “W-wait. T-too much.” Suddenly, a second orgasm rocks your body that leaves you gasping. Your legs have lost their feeling, and you couldn’t stand even if you wanted to.

Gyomei pulls you into his lap. He hugs you into his chest, his hands snaking under your stomach to lift it gently and provide you some sort of relief. You sigh contently now that some of the weight was lifted.

“Are you alright my love?” Gyomei asks, kissing the back of your neck.

“Mm..” Your cheeks flush as you can feel your husband’s straining erection by sitting on his lap. His hard cock presses against his pants, yet he makes no effort to deal with it. “M-mei, do you…um want some help with…”

Gyomei chuckles, his chest rumbling. “Please do not worry about me, love. Your comfort and pleasure is my first priority.”

Rengoku Kyojuro: Flame Hashira

Like Uzui, Rengoku came out of retirement to help with the Hashira training. His session would take place after one passed Tokito’s endurance training and focused on working on Total Concentration Breathing.

Seems easy, no?

Reality is most people pass out due to their inability to regulate their breathing correctly, thus having to start the process all over again. Your job is to go around a bring water to keep the slayers hydrated. But most are unable to drink due to the constricting feeling of the lungs after trying to recover from constantly using total concentration breathing. That along with the other physical strains it puts on the body. So you just do your best to encourage people to drink when they can.

“Come now! You must focus on the flow of your breathing and raise your awareness of your entire body!” Your husband’s loud voice carries across the training grounds. You can even hear him when inside. “Mastering this will even allow you to detect the most hidden injuries and slow the progression of poisons”

“Darling, don’t overwork them,” you say, coming outside with a new pitcher of drinks and cups. You offer him a cup, which he gratefully takes. “Let them catch their breath first.”

“Very well! 3 minutes then we shall start the next rep!”

You can feel all the gracious looks from the junior slayers as they can finally recuperate for a moment, even if brief. You know your husband isn’t intentionally trying to be harsh. He just gets so passionate about something and sometimes seems to forget that others do not possess the same strength or stamina as him.

“Hello? Rengoku-San?” A familiar voice calls out. It’s a face you and Kyojuro haven’t seen in a minute.

“Ah! Kamado! Long time no see!” Kyojuro exclaims. “I’m glad to see you’re in good condition!”

“It’s good to see you again! You too, Y/n-san!”

“I’m glad you’re doing well,” you say cheerfully. “Good luck with the training.”

Since Tanjiro had already had some experience with Total Concentration Breathing, his session was slightly modified. He’d have to tackle the XL gourd, bigger than the one he did at the Butterfly Mansion and then would spar with Kyojuro. If he stopped his Breathing he’d have to restart. But before any of that, for a warm up, all slayers had to run a 5K while maintaining their breathing.

By the time the sun set, just about everyone was passed out, beyond exhausted from the day. Kyojuro was still in overly good spirits, and full of energy as if the training didn’t even cause him to break a sweat.

“Kyo, I think it’s best to call it a day,” you deadpan.

“Really? But it’s not even dark yet?” Your husband has the most innocent look on his face.

You frown but then an idea strikes you. You lean in close to Kyojuro so that others around you can’t hear the next filthy words that leave your lips.

“If you still have so much energy left, why don’t you use that to put a baby in me like you’ve been wanting.”

You walk off without letting him respond, so you miss the way Kyojuro’s face explodes red. He rambles off some sort of excuse to the other slayers about training concluding for the day before rushing off to find you.

You wait patiently in your room, undressing so that you’re in nothing but your underwear by the time your husband arrives in a frenzy. Kyojuro’s face is flushed, chest chest heaving. The moment he spots you, he picks you up and pins you to the nearest wall, kissing you with urgency.

You groan as Kyojuro’s tongue forces its way into your mouth. His hands gripping the meat of your thighs tightly as he presses his growing erection against your exposed core.

“Feel so big, Kyo,” you whimper, rolling your hips against his.

“My flame, did you mean what you said earlier?” Kyojuro pants, his voice husky and airy as what little restraint he had started slipping away. He needed to fill you up and feel you around him bad, but he wouldn’t unless you were serious.

“Put a baby in me, Kyojuro,” you all but demand.

“If that is what my lovely life wishes,” Kyojuro chuckles. He lays you on the futon and sheds his clothes quickly. “Then I shall fulfill.” His cock is already stiff against his abdomen, twitching in his hand as pre cum oozes from the tip. You trace your fingers down his scared torso, noting the way Kyojuro’s muscles tense at your touch.

“I can’t wait to see what you look like when you tummy’s all swollen and full with my child,” Kyojuro said, aligning his cock at your entrance, his cheeks flushed. “You’ll make such a good mother.”

In a single thrust, Kyojuro sheathed his cock into your cunt to the hilt. The penetration left your eyes watering, crying out in pleasure. Kyojuro groaned. You felt so snug and warm around him that it took everything to keep from pounding into you right away.

“G-gods…you feel so good…”

“K-kyo, m-move,” you beg, trying to move your hips for some sort of friction.

Kyojuro grunts. He pins your legs to your chest, With a languid roll of his hips, he experimentally pulled his length out from the clamp of your hole. And with a sharp snap, he drove himself back into you. The sheer force of his scorching length shot the first wave of pleasure through the both of you. The two of you let out low moans. That first penetration gave way to a succession of increasingly rougher thrusts that had your body burning with pleasure.

Kyojuro’s body shuddered slightly anticipation. You clung to him and dug your nails in his shoulders trying to keep him close. The way his cock stretched you out had you feeling so full and lightheaded, leaving you babbling his name like a mantra.

Kyojuro groaned. He hovered over you, leaning down the kiss you passionately. His hands trailed up side to your nipples that became erect from pleasure. Lips trailing up the side of your neck, he left several bite marks.

"Ah a-ah t-that feels funny." You squirmed. "Kyo ~"

The sound of you moaning his name made Kyojuro’s cock throb. He fumbled slightly, his aggressive and frantic rutting becoming slower and slightly sloppy, instead.

“Ugh, coming,” Kyojuro groaned. He buried himself all the way to the hilt inside you. His orgasm hit and it hit hard. His dick pulsated with each subsequent spurt of cum. His hips still as he emptied inside you.

Your eyes roll to the back of your head as you feel your insides snap. Your pussy clenching tightly around Kyojuro, practically milking him as your own high shakes your body.

“S-shit,” Kyojuro gasps. He pulled out of your abused hole, watching the way his seed trickled out. The sight made his dick twitch. “This won’t do,” he chuckled while pulling your legs up around his waist. “At this rate, I won’t get you pregnant. Guess I’ll just have to fill you up again and again until it sticks.”
