Kokushibo couldn't help but clench his teeth as a growl erupted from his throat. The demon was stalking throughout the dark deep forest. Trying to steady his breathing as it had begun to grow irregular for some unknown reason. His chest feeling as though it were closing in. He wasn't sure what exactly the cause of it was. But whatever it was, was beginning to get on his last nerve. Not to mention the fact his body felt as though it was on fire, it also didn't help him that none of his concentration breathing seemed to have been helping him improve as well. He even tried to walk underneath a waterfall to see it could help cool his body temperature for god's sake! Even that was all but a failure in the end.

Yes. He was sure that he was at his wits end.

He was absolutely furious. His hand soon found its way towards the handle of his Katana. He couldn't help but grip it tightly in frustration. He was getting sick of this feeling. Why was his body acting this way all of a sudden?! He only hoped that he wouldn't run into those pathetic excuses of the demon slayer corpse. Or maybe he did. As he'd only end up using them for his relief as he tore them to shreds. Soaking in their screams of pain and agony as he tore into their flesh, ripping them apart. Piece. By. Piece.

His ears soon heard the sounds of quick and somewhat silent footsteps quickly making their way towards him. And from the scent that came from then. He could immediately tell it was a human. He guessed his prayers were somewhat heard. He thought at the familiar sound of a sword being drawn.

Taking out his own, he was quick and easy to deflect the person's attack. With a swipe of his katana, the unknown attacker was easily swung back and thrown to the floor. Though, with a quick grunt they were quick to leap onto their feet once more. Kokushibo paused for a moment until the dust that flew up in the air soon faded revealing his attacker.

It was in fact a demon slayer, but not just any one. It was a female one at that. He huffed in annoyance. "You've made the wrong decision… In choosing to fight me.. Little slayer." You couldn't help but shiver when hearing the demon's voice. It was deep and honestly, a bit intimidating. And it didn't help that you finally had noticed the kanji engraving in his eyes.

Uppermoon one…

The strongest out of the twelve kizuki. You were sure to be doomed if you went onwards from here. The feeling of sweat of uneasiness fell from your forehead but nonetheless, you gripped your handle tighter. Even if you knew you would be killed in the process. You would try your best to slay him, it was your duty as a demon slayer after all.

Seeing how you took a stance, Kokushibo only hummed. He'd make sure to be quick and get rid of you. He would usually humor them, make it look like they had a chance up against him. But in the end, all their efforts were pointless as he'd just slash them with a quick swing of his Katana. Ending their life's right then and there. But tonight was different. His whole entire body was defining him and what he wanted. Which meant that he held little to no patience at all.

But maybe after dealing with you. He could finally try and calm himself with whatever was happening in the beginning. Seeing that you were the first to take charge, kokushibo was quick to block your attack. Not too long after, he also swung his own sword.

Soon all that was heard around the both of you were the sounds of your katanas clashing against one another. That and your grunts as you tried your very best to dodge every attack he swung your way. You and he both were surprised that you'd managed to live as long as you had now. Even if you were now covered with cuts from the attacks he did manage to land on you. All the while kokushibo stood tall with little to no damage on him. Through, he'd just regenerate if he had been hit.

With one final swing you had just barely managed to dodge it but was completely taken off guard by a strong kick that was sent towards your stomach. With a forced cough you were soon forced back making you lose your grip on your katana.

You fell with a grunt as you slid onto the ground. You could only pant as you had grown too tired. You were no match for him, that much kokushibo could tell. But he did applaud that you managed to fight as long as you had. Even if you weren't a hashira. At most you were a kinoto.

"You've managed to survive this long… not many do…I applaud you for that." He spoke out. He continued to watch as you tried to lift yourself up from the ground. God, you looked absolutely pathetic. He couldn't help but think as you tried to crawl your way over towards where your katana layed.

Making his way over towards you, kokushibo soon stood over your body. Lifting up his left leg, he placed it on your back forcing the top part of your body to the floor. You grunted from the force as you still tried your best to reach for your katana. "You fighting is futile… just accept that your life will end…by my hands. " he muttered.

Pressing more of his weight down on you, you couldn't help but grunt in pain as you were being pushed further into the ground. You had to get out of this! You soon began to shuffle every which way you could, trying to release his grip on you. "Let me… go!" You shouted in a growl.

Kokushibo couldn't help but look down on you in amusement. You reminded him of a small and helpless little animal that was about to be devoured by its prey. So weak and defenseless. He kept his gaze on you, enjoying the way you struggled beneath him. His gaze soon stopped on your bottom that was still well in the air swaying side to side as your arms had a firm grip to the floor as you tried to lift yourself from the ground.

Kokushibo couldn't help but notice how his eyes seemed to have been fixated on your action. The way your hips moved as though it were in a taunting manner. He didn't notice how he removed his leg from your back. Or how his hands had moved unsubconsciously lifted themselves until they were firmly grasping onto your ass causing your body to tense and jolt upward in surprise.

"H-hey! What the hell do you think you're doing!" You shouted towards him with a growl. Kokushibo only ignored your shouting as his thumbs began to rub against your ass causing you to freeze in place. Kokushibo also felt his own body heat rise up more than before. Only this time almost growing unbearable. Not to mention how he felt his blood shot through him and directly down towards his groin. And it also didn't help him with the fact that you seemed to have been wearing a skirt than pants like other slayers would have. Honestly, what was up with that?

'Shit', kokushibo thought, his teeth gritting against one another in annoyance. As your skirt had hiked up a tad bit, giving him a little more view on what was underneath. His body seemed to have reacted to it. He knew exactly what was going on. He didn't know how it could have possibly slipped past his mind.

The demon was in heat.

Kokushibo always made sure to keep the thought in mind. He'd always plan ahead to take care of these kinds of things before it escalated too quickly. So how did it manage to pass him this time? He huffed, it didn't matter now. Now that he finally knew what was wrong with him. He knew exactly what to do in order to relieve himself from it all. And who was it that was going to help him through it as well.

"Here's what is going to happen." He mumbled while lifting up one of his hands that held his weapon only to slam his Katana down to the ground as it dangerously landed far too close to your neck forcing you to freeze and listen."You will allow me… kokushibo, upper moon one of the twelve kizuki… to use your cunt as I so please...to help relieve me from my heat". His… heat? You were in deep thought, you thought you had heard of demons going in heat before. But it was rather strange if you had been honest about it. You also thought it was just some joke some slayers of the corpse made up. Guess you were wrong-

His grip on your ass tightened, you gasped when feeling his sharp nails begin to sink into your soft flesh. That and the fact that something hard began to poke your bottom as well- "And in return.. I will allow you to live. " Kokushibo bent over his body to loom over yours. "How does that sound… little slayer" he purred.

You crunched your nose in disgust. A groan was torn from his throat when feeling your ass began to move, managing to rub against his groin as you tried to release yourself from his grip. "Like hell! Get the fuck off me! As if I'd let a demon such as yourself have their way with me! " you hissed towards him. All while the more eager to get him to let you go.

Though, it only triggered him to buck his hip forward making you jolt forward from the force and being able to feel more of his erection. You couldn't help feel your face heat up when feeling just how large it was. God, this was bad. This was very very bad! -

"Shame, you didn't have much of a choice…" He chuckled down towards you. His hand that was once on his Katana was brought back to your ass. With a tight grip, he pulled you back on to his bulge making you gasp- "I was going to fuck you anyways… you only get to decide whether…you lived of not. " he added as he began to slowly grind himself against you causing you to yelp at feeling more of him.

"But do not worry… " he muttered as his right hand slowly began to move its way under your skirt and towards your core. "I'll make sure to pleasure you as well… just before I kill you." Your legs immediately tried to close on themselves to try and prevent him from reaching further. This only made him huff in announce as he kneeled to the ground. His thighs forcing their way between your legs forcing them to spread themselves wider like before.

"Didn't I tell you before… " he growled as he slightly bent forward allowing his chest to press against your back to keep you in place. All while two of his fingers began to lightly graze themselves against your covered lips making you whimper. "You fighting me is futile. Just give in… Won't you? " he huffed into your ear as he grasped onto your underwear. Giving a rough tug, he managed to rip it off from you, making you gasp at the force.

Lifting the two fingers that were against your core. He brought them up against his lips before allowing his tongue to lap around them, coating them with his saliva. Once he deemed that it was enough to use as lubricant he brought them back down to your quivering lips before carefully sliding them into your opening making you gasp. "H-hey- w-wait a minute! " you clenched your eyes shut when feeling him slowly drag his fingers out only push them back in. "I told you before… just give in" he grunted before nuzzling his face into the back of your neck just before lightly nipping at the area.

Your eyes squeezed tighter while you gritted your teeth in a scowl. One of your hands immediately went down to try and force him to stop, all while the other tried its best to keep your body up. But it was no use when your body began to tremble at the feeling of his fingers stretching, opening your walls wider. "W-what do you think you're- doing! " you cried out. Kokushibo only hummed, "I'm only preparing you of course… I'm quite large and wish to not… break you this early on. "

"Well, stop it! " you hissed your hand finally being able to grasp onto his wrist. "Why? Your body seems to be finally reacting to my advances properly. " you bit your lip to try and hide a groan as you felt his fingers pump themselves deeper into your entrance. God as much as you hated it. He was right. You couldn't deny it as you felt yourself growing wetter as he kept thrusting his fingers into you. And by god did it feel good too. But it wasn't like you'd ever let him know that. You let out a Yelp at the feeling of his hand twisting in a new angle, this allowing his thumb to brush against your clit. Your grip on him tightened in anticipation.

A whine tore out of your lips when his thumb began to slowly make circles against your bud. "Not to mention it sounds like you…my little slayer.. Are beginning to enjoy this as well. " he cooed as he continued to toy with you. You turned your head as best as you could to give him a glare. "Like hell! As if you could ever make me e- enjoy- OH GOD! " You were cut off by his pace beginning to pick up speed making the hand that held on to him fell to better hold yourself up. And your head went limp and as a whine was being torn from your lips. Kokushibo's eyes squinted in delight, enjoying the control he seemed to have on your body.

"Oh really?" He began as you covered your mouth to try and hide anymore noises coming out of you. Your eyes began to roll in pleasure at the feeling of him curling his fingers. "Because it seems to me… your body is telling me otherwise" your hand began to muffle your quiet moans as you shut your eyes closed to focus on holding yourself together. Your breath hitching at the feeling of a building pressure beginning to form. "And by the way you're clenching on my fingers alone… I'd say you're close to coming undone… are you not, little slayer? " he asked in a whisper, his body still bent slightly as his lips brushed against the shell of your ear. His warm breath caused your back to arch and your cheeks burning up as he placed a firm kiss just near below your jaw. God, the way he spoke was driving you insane.

"Fuck.. You- AH! " you shouted as his thumb that still circled against your clit swiped it one final time before you felt your climax come crashing down. "Oh fuck! '' You cried out, your hand that covered your mouth slammed onto the ground, your body shaking from your sudden release. Kokushibo only chuckled at this, his fingers still pumping inside of your now dripping cunt. "It seems as though… I was right." He purred as he felt your arousal begin to drip down his hand. He gave your now swollen bub one final brush making you shutter until he finally pulled himself off you, a whine leaving you as his fingers also finally withdrew from you as well.

Kokushibo couldn't help but stare down at you. You seemed to be in a panting mess, trying to catch your breath. Your legs still slightly shaking from your orgasm. Humming, he hiked up your skirt higher now fully showing your name ass to him. He even managed to notice how some of your own slik slowly slid down against the inner of your thighs. Your hole clamping against nothing at the sudden loss of his fingers that were in you moments before. He couldn't wait any longer at the feeling of him growing harder.

Releasing you from his hold, he hastily began to remove his kimono off him as his body heat grew to extreme to his liking. His hands immediately fell to his silk belt from his hakama pants. Undoing the tie, he tossed it carelessly to the side, soon after sliding his pants down just enough to free his length. You who was still trying to get a hold of yourself together, didn't seem to notice him lining himself to your entrance until you felt his left hand fall against your ass check as he began to give it a light massage and the way his tip began to rub itself against your slik puffed lips making your gasp.

"I'm going to put it in now. " he warned you as he continued to lubricate the crown of his cock against your slit. Your eyes widened, your face heating up more from embarrassment at his words and at the feeling just how large he was. "W-wait Wait! T-there's no way you're going to make that fit! " you cried out. He huffed as he got himself more comfortable behind you. "Believe me when I say, it will… I'll force it if I have to anyway." He growled, slowly beginning to push his hips forward allowing his length to finally push inside of your hole. Your eyes feeling like they were bulging out at the feeling of him stretching you open making you whimper as tears began to form and fall down your face. All while kokushibo groaned at the feeling of your walls clamping down against him as they tried adjusting to his length. Loving how you were soaking from your previous orgasm allowing him to easily push himself through.

"See-" he grunted out as he slowly pulled his length out half way before pushing it in once more, stuffing you full- "it fit in perfectly… almost as if you were practically made for me in fact. " he teased as he rolled his hips before continued to have his way with. You on the other hand were a quivering mess. You didn't even have the energy to curse at him. Not when he was pushing his large cock into your quivering cunt. Your face flushing from hearing the sinful sounds coming from both your bodies as he thrusted himself in. Not to mention how you began to become more vocal to it as well.

You bite back a moan at the feeling of his tip brushing against your sensitive spot. He must have taken a noticed as he smirked. "Oh? Did I hit something? " he grunted, his thrusting pace begining to pick up. "By the way your clenching against me… I think I did. " he taunted with a Huff. You turned your head to glare at him. "Shut- Ah! Shut up! " you whined your face warm with embarrassment, moaning as he grabbed your ass in a firm hold and slamming himself into you hitting the exact same spot making your eyes roll.

"Ah fuck! " you mewled out in half pain as his grip on you was to harsh and in pleasure at him hitting all the right places making you grip the grass below you. Kokushinbo only let out a grunt at the feeling of your heat tighten on his cock. He didn't remember the last time he ever felt this good during his heat. Looking down to you, his eyes half lidded as he was to caught up in his own pleasure. Looking down he couldn't help but enjoy how your body seemed to jolt with every hard thrust of his hips. He began to rub his thumbs against your ass massaging it, loving hearing how hard you'd try to hide your moans from him.

It was clear to him that you were indeed enjoying yourself. With the way he'd notice how you'd try covering your mouth to hold in those cute little moans. Or the way your legs would tremble with every harsh thrust, not to mention how utterly wet you've become making an absolute mess on him. Your cunt gripping onto him wanting more of him. And lucky for you. He'd glad do just that.

Letting go of your ass with his right hand. He let it glid down your body enjoying the way how it made you shiver. Placing his palm on the center of your back, he gave you a firm push sending your body further to the ground. "Stay like this for me… won't you? " he asked making you shiver at how low and seductive his voice sounded. His hand returning to your ass. You mufflled a moan, your back arching at the feeling of him going slightly deeper into you. God, you'd have been lying if you said you weren't beginning to enjoy it. As much as it pissed you off as a demon of all things were making you feel this way. He was making you feel the best you'd ever had with anyone you were with before.

Your eyes widened with shock as a cry tore from you when feeling him thrust deep into you. Your fingers digging themselves into the floor below you as you could feel him push his way further, his tip just kissing your cervix. "My god! " you cried in utter bliss. Not being able to contain your moans any longer as you continued to cry, your head laying on the floor. Not even caring of getting your uniform dirty anymore dirty than it already was from both your previous fight. Even going as far as spreading your legs further apart to allow him more room. Not to mention how you also pushed yourself against him showing signs of wanting more of him.

Kokushibo groaned at this. His eyes closing tightly until opening one of his six eyes to stare down to your quivering body. He couldn't help but smirk, " You know… " he began lowering his voice. His body leaning over, allowing you to feel how muscular he was to lay against your back. One of his arms resting beside you to keep him up while the other was kept on your ass keeping you secured." By the sounds coming out of your mouth… I'd say you were actually enjoying this. " withdrawing his hips back, be pulled himself out your soaking wet pussy with just the crown of his cock still in. Whimpering at the loss feeling of his dick in you. Lifting your ass to push more of him back in, you whined when his grip on your ass kept you in place making him chuckle.

"To think, a demon. The very thing you swore onyour life to slay…is making you moan this sinfully. " he breathed heavily just against the shell of your ear making you tremble. A gasp leaving past your lips as he thrusted his whole length deep into you making you cry out. He angled his hips making sure to thrust deeply into you making you moan and cry below him, soft cries begging for more. "Are you enjoying yourself…my little slayer?" He purred just beside you letting his breath tickle your ear. You nodded your head, moaning as he began to nip at your it. "Use your words slayer. " he growled, his rough callous hand giving you a harsh slap on your ass making your jolt and nod more frantically, "y-yes! God yes! It feels amazing! " you managed to rasp out fat tears rolling down your cheeks at a familiar tight knot beginning to form.

Kokushibo immediately took note of this as he felt your walls begin to flutter against him. "Is the little slayer about to come again? " he taunted fucking your a bit harder. But with the way you tilted your head against him and a moan being ripped out from you. Leaving him to assume you didn't mind. "Don't worry, I am as well. " he grunted, the feeling over his own orgasm coming soon as well this making you cry out more.

He began to give you kisses against your skin. Sometimes even allowing some of your skin into his mouth as he sucked on it harshly making sure to leave a mark. "Won't you moan my name little slayer? " he breathed against your ear once more making you shutter. "Come on little slayer… moan my name out. I know you, know it. " he coached his hips beginning to stutter. "Moan it as you make a pretty mess with your cum on my cock" this seemingly to make the knot in you snap.

"K-kokushibo~! " you mewled while finally Cumming onto his cock that was still being pumped into your now soaking pussy. "That's a good little- little slayer" he growled against you making you moan. "That's a good girl. " he panted as he gave you a few more thrust before one hard and powerful thrust causing him to groan and your back to arch in a moan at the feeling of him realising his own seed in you. Your eyes rolled at the feeling of him filling you up making your mouth fall open and a loud moan come out before your head fell to the ground in a panting mess. Kokushibo gave a few more thrusts before allowing himself to take a breath before lifting himself off you all while letting go of your ass and finally withdrawing his cock out of your dripping hole. This causing your body to fall limp onto the floor leaving you still trying to catch your breath.

"Well, that was most enjoyable now was it. " he huffed as he stood up and began dressing himself. You only having the strength to give him a side eye. "Will… will you kill me now like you said you would" you managed to whisper out, but nonetheless catching kokushibo's ears. He gave you a glance. You were panting, eyes half open as you grew to exhausted, and your legs slightly twitching every few minutes.

He hummed deep in thought, he had said he'd kill you wouldn't he? His gaze was locked into your quivering and most likely now sweaty body. Though, you had made him felt ways he hadn't before with another. And if something like this were to happen again. He wouldn't mind using you once more. "I won't kill you-" he began, turning to you fully as he started to make his way to you. Standing in front of you, he squatted while reaching a hand out to take a strand of your hair.

"But, I do have two options for you. " he said as he began to play with your hair. "You either come with me. I will make sure no demons would ever come near or harm you…You will be sheltered, clothed and fed…All while allowing me to take you when my heat or any time I wish. " your eyes widened hearing this. Was he… was he actually serious?! He let go and raised a finger to lay against his lips "that- or have your fellow slayers such as yourself find you like this, all beat and used by a demon…I'm sure you'll have a very fun time explaining how you allow a demon… the strongest of the kizuki nonetheless to have its way with you… you chose little slayer… what will it be? " he hummed.

You were left frozen. You'd either stay with this demon. One who's lived how ever many years on this earth, who's taken who knows how many lives of innocents. And all while allowing him to have his way with you whenever he pleaded? Was he insane?!

But then, you thought of his other option. He was right. How were you going to explain to the corpse members how you layed with a demon? Sure it might pass as he was clearly stronger than yourself. An upperank of all, you were no hashira. There were absolutely no way you'd kept up with them. But even then, you also know how they'd also look down on you. Call you the one who'd allow a demon to have its way with them. No one would ever look at you the same. No one would ever respect you the same.

Looking back to him, your eyes wandered his body. His kimono yet to be put on allowing your eyes to wander. Your face heated up, now that you had a better glance at him. He was a rather attractive one if you had been honest. He looked to be a male somewhere within his late twenty's. His chest was rather toned as well. If he stated to take 'care' of you. You honestly began to not mind at the thought. Even if that did technically meant that you'd be going against the corpse. Oh what the hell-

"I'll… I'll leave with you. " you panted your eyes struggling to stay open before closing. You heard him chuchle, hearing some shuffling. You felt yourself being lifted into the air what felt like muscular arms wrap themselves around you. "That's a very well choice. " kokushibo chuckled walking away with his things in his other hand. Pressing a kiss against Your head that was resting against his bare chest.

"Let's leave to your new home… my pretty little slayer"
