Chapter 1: First Phases

Chapter Text

Pain. Agonizing pain. It was all he felt. All he could focus on. It brought him to his knees. Made him groan and whimper in pain. The gapping hole in his chest gushed blood and he coughed, blood splattering onto the ground. He sucked in a raspy breath and tilted his head towards the sky.

Tears flowed freely from his eyes as he mumbled a prayer, begging Buddha, anyone, to save him from this torment. It felt like fire shot through his veins and he gritted his teeth. He fought hard to fight back the darkness that crept into his mind, seeking to drag him under.

*Am I going to die?* He thought to himself. *Is this the end of the Stone Hashira? Is this the end of Gyomei Himejima?*

"Most people die within seconds from that amount of blood..." The soft, sinister voice said with amusement. It drew Gyomei back to reality. "But you are still here... Interesting. You truly are the strongest of the demon slayer corp."

Kibutsuji Muzan. The first demon. A blight.

Gyomei practically snarled at the man, before crying out in pain as the fire reached his gums. His gums bled as his canines sharpened and elongated. A snarl rumbled in his chest as he fell over, his hands just barely catching himself. The fire in his veins traveled to his fingertips, straight to the tip. His nails grew into long black claws. Claws that could tear into flesh and bone with ease.

*No. No. No!* He couldn't believe this was happening. Couldn't believe he was turning into the very thing he hated. The very thing he swore to kill.

His large hands shakily moved across the ground, searching for his blade. He'd cut his own head off. Ending his life for good before he was too far gone. His memories were already beginning to fade and he felt this burning need. The need to consume human flesh. He felt his fingers brush against his blade, but before he could grab it, Muzan kicked it clear across the field. He gritted his teeth at this.

"Tsk tsk..." He laughed. "Can't have you doing that now can we?"

Muzan smiled with sadistic glee as he watched him writhe in pain. He fell onto his side and curled into a ball, his soft cries music to the demon's ears.

You watched in horror as your beloved sensei convulsed and shook. Muzan had given him so much of his blood you were sure the change would kill him. You tried to move. To get up. But the foot on your back applied more pressure and you gritted your teeth. You were sure your spine was going to break.

"Stay down weakling." He sneered. He dug his heel into the middle of your spine and you nearly screamed in pain.

Gyomei's head turned toward you in response to your cry of pain and he snarled. Fighting against the scorching fire in his body, he stumbled to his feet, his body facing toward you and Akaza. He bared his sharp teeth in a snarl and flexed his fingers. You saw a row of horns begin to grow from the scar on his head. The two horns on either side of the row were the largest, at least a foot in length once they finally stopped growing. His skin began to darken a bit, turning a light shade of gray and black markings formed around his eyes. His body grew in size, tearing through his clothes. He must've grown two feet at least. He had also grown a large tail with a large rattle at the end. His feet morphed and elongated, talons tipping his toes which went from five to three. He looked horrific. Like a true monster.

Gyomei's breath left him in deep growls as he stared menacingly at Akaza. You could sense Akaza's uneasiness. And you yourself had to admit that the way he stood there, starring Akaza down, frightened you.

"Can... Can he see me?" Akaza asked hesitantly.

Muzan cocked his head. "His eyes haven't changed. He hasn't gained any sight. His senses as a human were impeccable so I'm sure as a demon they're even keener." Muzan had to admit he was impressed with Gyomei's strength. Muzan poured buckets of his blood into Gyomei's body. Even less than that amount would've killed any other human. But not this man. Here he stood, changing into a demon and staring down the Upper 3rd of the Kizuki.

Gyomei snarled and took a step toward Akaza. Akaza growled back and flexed his claws. "Try me bitch" He snarled.

Muzan rolled his eyes. "We need to go Akaza. The sun will rise soon."

Akaza nodded. Even though he wanted to face off against this beast, he knew better than to disobey Muzan. So Akaza stepped off of you and turned/ He paused however. With inhuman speed, he turned and kicked you hard, sending you flying toward Gyomei. Gyomei roared at Akaza but made no move to charge him. Akaza laughed and ran into the woods. Muzan gave one last look to his new "child" before disappearing.

You panted heavily, each breath causing excruciating pain to assail your body. You were sure that damned demon had broken a few of your ribs. Black dots began to appear in your vision. You fought hard to stay awake as you rolled onto your back. A deep growl shook the earth beneath you and you looked up. Gyomei was looking down at you. Tears were streaming down your face as you gazed upon him. The man you'd trained under. The man you'd loved from afar, too afraid to tell him how you felt. Afraid he'd reject you. You reached a trembling hand toward him before the darkness consumed you.

 

------------------------------------------------------------------

 

*What... What is this feeling?*

It felt... good. Amazing even.

Pleasure coursed through you, stemming from your core. It made you tremble and moan.

*Feels so good~ Am I dreaming?*

You felt something *enter* you which caused slight pain and your eyes shot open. You frantically looked around you, seeing nothing but darkness. It took a moment for your eyes to adjust to the dark and saw you were somewhere deep in a cave. It was cold and humid. The pleasure you felt earlier had returned however and that' when a horrific reality dawned upon you.

You were seated in Gyomei's lap as he sat with his legs crossed. Your kimono was all you wore and it was wide open. Your breasts and pussy were fully exposed. And Gyomei had a finger buried deep inside your pussy. His other hand had cupped both of your breasts and was fondling them. He was pumping his finger in and out of you. His sharp nail scraped lightly against your vaginal walls. It hurt but at the same time it felt so good. *Feels...* You shook your head.

"N-No!" Your hand shot out and took hold of Gyomei's wrist. Well, the side of it. Your hand couldn't get a good enough grip due to how big his wrist was. Nonetheless you did your best to try and pry his hand away from you and at the same time attempted to get away from him.

His arm moved to wrap around you, pulling you close to his body Your back was now pressed to his front and the speed at which he finger fucked you quickened. You let out a surprised shout and kicked your legs.

"G-Gyomei! No! Let me go!" You clawed at his arms and kicked his thighs. He continued to ignore you. He added another finger, stretching you. Your pussy clenched around him as it coated his fingers with your wetness. Your stomach and uterus began to tighten as a growing pressure began to build and build. "No..." The pressure inside reached a peak that became unbearable and everything spilled over. You bit your lower lip to keep from screaming as you came onto Gyomei's fingers. You expected him to stop. Thinking that your embarrassing orgasm was what he wanted. But he didn't stop. He added in yet another digit, now stretching you with three massive fingers. And when you say massive you mean MASSIVE. Each finger is roughly two and a half inches in diameter.

You whimpered and tears stung your eyes. "Gyomei..." You breathed out. "Please... stop..."

But he didn't. He kept pumping his fingers in and out, making you cum over and over until you eventually passed out from exhaustion.

 

------------------------------------------

 

When you next awoke you could hear soft snoring and you felt your body slowly rise and fall. You felt an unbearable soreness from between your legs from the brutal finger fucking Gyomei had given you. You blinked open your eyes and looked around. You were still in the cave, still dressed in only your kimono. You were laying atop Gyomei's chest, his rapid heart beat and deep snores all you could hear. The sound of his heart made you swoon and you found yourself snuggling into his chest.

*Gyomei...*

*What are you doing?! Get out!* You shook your head. You needed to get out of this cave. Needed to get back to HQ and-

No... What would you tell them? 'Hey, so, Gyomei is a demon now. Please don't kill him!'

Yea, like hell that would end well. They would surely kill him... The thought broke your heart and you felt you'd cry. *I have to do something!* And there was nothing you could do sitting in this cave. So, carefully, you sat up and slid off of Gyomei's body. You didn't bother looking for your belongings because there was not enough time. You licked your finger and stuck it up in the air. You felt your finger grow cold and after holding it at different positions, you found where the wind was coming from. You began to slowly tiptoe towards that direction, careful not to make a sound. Your heart beat hard in your chest and you listened closely for any kind of movement that wasn't your own.

You saw the faint sign of light and you grinned. "There." Just as you neared the cave's entrance a booming, pained roar shook the cave. Your eyes widened and you broke into a sprint. The cold wind of winter bit at your face as you ran out of the cave. You didn't dare look back, for you heard Gyomei give chase after you. Your body ached badly, but you did not let up. No matter how much your muscles protested. *Got to get away!* You didn't know where you'd go but that cave was the last place you wanted to be.

Another roar shook the earth beneath your feet, causing your balance to be throw off. You yelped as you tripped and fell. The snow cushioned your fall as you fell face first. Well that was embarrassing. You quickly stood and shook herself out. *Fuck that's cold...* You heard the snapping of branches and booming footsteps. *Oh fuck!*

You began to run again, pushing yourself to run faster than before. You could hear Gyomei gaining on you and you began to panic. You can't get caught. You just can't.

You could hear him gaining on you. Practically feel his breath on your neck. *Go. Go. Go. Go! GO!*

"NO!" A voice boomed just before you felt someone snatch your kimono. You screamed as you were yanked up into the air. You quickly maneuvered yourself out of the kimono. You fell to the ground and landed in a crouch. The cold air nipped at your skin and you shivered. You went to run again but something wrapped around your waist. You were lifted into the air, kicking and screaming.

"Gyomei no! Put me down!"

Gyomei reached for you, grabbing onto your hips as his tail unwrapped itself from you. Gyomei brought your sore cunt to his face and his long, hot tongue licked up your swollen folds. You sucked in a sharp breath and your body tensed. You saw Gyomei visibly shudder. The sight of his enjoyment from your taste shamefully made you wet. Gyomei growled, clearly sensing your arousal. His long tongue glided over you once more before it parted your slick folds and pushed into your sore hole. You whimpered and tried to close your legs. But Gyomei's head prevented that. Your hands tried to push his off of you, but couldn't manage to do so. His tongue pushed so deep into you that It drove you crazy. Soon his lips made contact with your cunt and he opened his mouth, fully covering your nether region. He sucked on your wet pussy as his tongue wiggled inside you.

You could feel your resistance begin to slip as delicious waves of pleasure traveled from your womanhood throughout your body. The cold wind on your hardened didn't help at all either. Pair that with the assault on your pussy, and you could feel your desire to fight in that moment subside.

"Gyomei~..." You couldn't stop yourself from the moans and whimpers that left you. Couldn't stop your hands from tangling in his soft black hair and pushing his head closer to you.

*No! Fight! Get away! Fi-*

An explosion of pleasure shot electricity through your body and you screamed in pleasure as Gyomei made you cum into his mouth. "Gyomei!~"

He kept assaulting you there, giving you a feverish tongue lashing. You panted heavily and whined as your feet pushed against his shoulders. "P-Please... No more... Please..."

Gyomei reluctantly pulled away and licked your wetness from his lips. He growled softly and moved you to cradle you in his arms. He used his body to shield you from the cold as he trudged through the snow, making his way back to the cave.

You protested weakly, but knew it was no use. Besides with the storm raging around you, you'd die out here long before you found civilization. So, you let him take you back to the cave. *I'll figure a way out somehow..."

 

------------------------------------------------

 

Gyomei sat down and placed you in his lap. You looked up at him and saw his head was tilted down but not facing you. His eyes were closed as he held you close to his body. He was purring as he held you. He held you as if he was afraid you would run off again. He wasn't wrong to feel that way if that were the case. Don't get it twisted or anything. You loved him... Sitting here with him like this is something you dreamed of. But... THIS was wrong. He was a demon now. Who knew how long it would be before his demonic need to consume flesh caused him to look at you as a meal?

So, because of that... Even if you wanted to so badly... You didn't lean into his touch. You kept your guard up.

Gyomei clearly didn't like this and he hissed a bit. He nuzzled into you, rubbing his large face against your cheek. You turned your face away from him and he snarled. His hand gripped your jaw and jerked your face toward him. Before you could protest his lips were on yours. His tongue parted your lips and filled your mouth up. You felt it push far and down your throat, making you choke as it triggered your gag reflex.

Your hands reached up and pushed against Gyomei's chest. He growled into your mouth, the vibration somehow traveling down to your core. One of Gyomei's hands began to fondle your breasts as he kissed you and you couldn't stop your body from leaning into his touch. *Not this shit again...* He pinched and twisted your nipple and you yelped in pain. But the pain wasn't the type that made you want the whole experience to stop. No, it made you want more. Your hands went from pushing against his chest to cupping his face. He growled his approval and started to kiss you with more passion. His tongue thrusted in and out of your mouth as he pinched and pulled at your nipples. You couldn't help yourself as one your hands slinked down your body. Your fingers delved past your folds and began to circle your clit. The simple action had you nearly screaming into Gyomei's mouth.

*Stop... What are you doing?*

*I-I have to... I have to quell it. Quell the fire.*

Gyomei's tongue and lips left your mouth and you whined. "G-Gyomei..." You said, trying to press your lips to his. But he moved away, lifting you up a bit, bringing your breasts closer to his eager mouth. His lips locked onto one of your nipples and sucked and you cried out in pleasure. Your back arched, pushing your breast against Gyomei's mouth. He licked and sucked at your nipple as you pleasured yourself, your fingers moving to push into your tight cunt. You'd never touched yourself like this before, so you did what felt natural. And by the gods did it feel amazing.

Soon, you came like this and Gyomei pulled away from your breast. You pulled your hand away from your heat and looked down at your wet, sticky fingers. Gyomei moved and you watched as he sniffed the air and found his way to your fingers. You watched as his tongue flicked out and wrapped around your fingers. He licked them clean and the sight made you moan.

Gyomei's mouth stretched in a yawn and a sleepy growl rumbled through his body. He swayed a bit before falling to the ground. He helped you close to his body and you laid there as Gyomei gradually fell asleep. With the way he held you, both arms wrapped around your body as his tail around your legs, there was no way you'd be able to wiggle free.

*Damn...*

 

--------------------------

 

Gyomei woke to the sound of grumbling and your soft groans of discomfort. His hand traveled down and he touched your stomach. He felt it rumble and his ears twitched. You were hungry. He realized just now that you haven't eaten in... He frowned. He didn't know how long it's been. And just then his own hunger hit him. He sat up, careful not to wake you. He paid close attention to your breathing as he set you down upon a flat slab of rock. You whimpered but did not wake, instead curling into a little ball.

Gyomei turned to leave but then stopped. If he left you here alone then... who would protect you? What if you tried to leave him? He huffed and started to turn back to you but then once more stopped. You were starving. He needed to feed you. He didn't know why he had such a need to care for you, to keep you safe, to make you *his*... but it was a need that drove him to take you here to this cave. To keep you at his side. To claim your body.

"Food..." His baritone voice croaked. He hadn't spoken in... he didn't know how long. The glowing cracks on his body and horns glowed as he walked through the cave, and as he stepped out he waved a clawed hand.

"Blood art, moving earth." The mouth of the cave molded and closed shut. Holes also formed so that air would be allowed to enter the cave freely still. Gyomei didn't know how long he'd be gone and didn't want you to suffocate. Once he knew the cave was secure enough that no one could get in nor out, he began his trek down to the forest. He'd find you food. Something that smelled edible and that a human would enjoy.

His stomach grumbled and he groaned. "Need... food..."

-------------------------------

"Damn it!" You couldn't muster up enough energy to break the wall using your stone breathing technique, nor even cause a crack. You were so hungry and felt severely nauseous. You swayed, barely having any energy left to even stay standing. You needed food and water. You sniffed yourself. And were in serious need of a bath. It was also then that you noticed the wounds you’d sustained in your fight against Akaza had been fully healed. Hell, you were realizing that you haven’t felt the sting of pain from your wounds since you first arrived to this cave. *Did Gyomei… heal me?* You frowned. *Why?* Was some part of him caring for her? You thought back to last night, to how tenderly he touched your breasts. The sound of Gyomei’s pained roar upon realizing you’d escaped played in your mind once more and tears stung your eyes. Was your Gyomei still in there somewhere? Was this his twisted idea of showing you how he truly felt? You shook your head, wanting even more now than ever to leave this cave. *I need to get him help…* You raised your fists once more and focused on your breathing.

“Total concentration, stone breathing, third form-”

Suddenly, the stone wall that prevented you from leaving began to move like clay. An opening formed, allowing Gyomei to step through. You thought about running out of the opening, but Gyomei’s massive body blocked you and in your state, you wouldn’t be able to move faster than him. Besides, it didn’t matter anyway for the second Gyomei stepped through, the mouth of the cave closed once more. And the holes in the stone wall were too small for you to fit through.

You huffed. “Damn.”

The stench of metal wafted to your nose and you nearly gagged. *Blood. That’s blood I smell…* Your eyes widened in horror when you saw that one of Gyomei’s hands were covered in blood and the other was carrying a bloody carcass. You took a hesitant step back and you suddenly found it hard to breathe.

“Gyomei?” You said warily. “What did you do?”

He frowned down at you. “Food.” His voice was like a deep growl, and you barely understood the simple word.

“Gyomei please tell me-”

He held the carcass to your face and you gagged once more, taking another step back. Sensing your disgust Gyomei brought the carcass to his nose and sniffed. He frowned once more. He was sure this is what humans ate. He couldn’t remember much but he was sure of this.

He held it to you once more. “Deer. Food.” He stated.

You took a closer look and indeed saw that it was in fact half of a dead deer. It was the upper half, the buck’s dead eyes boring into your own gaze. You had never felt more happy to see a dead animal in your life.

“Thank you Gyomei.” Thank you for not killing a human.

He moved the deer carcass closer to you and you leaned away. “I can’t eat this.”

He cocked his head and you had to admit, the confused look on his face was so adorable. “Why?”

You couldn’t help the giggle that left you. “Because it’s raw.”

He cocked his head, but then gave a curt nod. He began to walk further into the cave and you followed. He stopped at the usual spot you could only call his sleeping area. You watched as he set up a pile of rocks. Gyomei set the carcass atop the pile and then piled rocks on top of it. Soon the entire carcass was encased in stone. You frowned but then your brows shot up as the stones began to glow. Gyomei heated the stones up, the smell of cooking meat filling the cave.

Gyomei sat down and patted his lap. You hesitated but reluctantly gave in. You had a feeling you were going to sit in his lap. Whether that be by force was entirely up to you. And so, you walked over to Gyomei and sat in his lap. You were sure, with the difference in size between you two, you looked like an infant sitting in his lap.

Gyomei’s muscled body leaned forward a bit, and his hands moved to rest on your laps as he drew you in closer to him. He purred as he held you to him, his eyes closed. You could hear the soft beat of his heart and it calmed you down ever so slightly. You leaned back into him and once again tears stung your eyes. He was being so gentle with you. Holding you as if he was scared you’d disappear. It made your heart swell and you couldn't help but think of the past.

—-------------One year ago—-----------------

 

Gyomei’s gentle hands upon your back nearly made you moan, your body relaxing from his touch. His fingers expertly kneaded the knots in your muscles, bringing you some much needed relief. It was the end of the first week of your training and you’d pushed yourself too hard with your exercise routines. You had tried to lift a boulder that was frankly too much for you to handle. Now to your credit you were able to lift up to shoulder level, before you ended up pulling several muscles in your back. You’d dropped the boulder with a pained shirek, the stone nearly crushing your foot if Gyomei hadn’t caught it.

He shook his head. “I told you not to strain yourself.” He said as he smoothed out another knot in your back. The feeling hurt but at the same time felt heavenly. It made your toes curl and you felt wetness pool between your legs. *How embarrassing, getting turned on from my teacher’s touch…* The way his strong hands rubbed your aching muscles sent tingles to your womanhood. He was so strong yet so gentle. His callous hands moving effortlessly over your smooth, bare skin.

You weren’t the only one being turned on by this interaction. As Gyomei massaged your back he could feel the tendrils of his own desire course through him and straight to his pulsing cock. His cock was hard and his balls tight. If he could see he knew that if he were to look at his cock right now, it’d be oozing precum. Due to his keen senses he could faintly smell your arousal and it almost made him groan. He got mental images of him impaling you upon his cock. He’d grip you by your hips and thrust up into you, straight to the base. He’d fuck you until he came deep inside you, filling you up with his seed. He wouldn’t stop there though. No. He’d lay you on your back and pound into a hole he knew was tight from never being touched before. Oh the way you’d squeeze around him as he pounded into you. He knew it would drive him crazy.

A deep blush tinted his cheeks and he shamed himself. How could he think such thoughts about you? You were someone who trusted him to guide you down the right path of a demon slayer, not take you with selfish need. Gyomei shook his head and mumbled a silent prayer as he continued to tend to your aching muscles. He brushed across a *sweet spot* on your back and felt your body tense. He heard a small “hmm” and it nearly undid him. You had moaned from his touch, and he wanted to hear it again.

You tried your best to stay still as Gyomei continued to massage the small of your back, barely touching your ass. You didn’t know why, but the way his thumbs rubbed circles on your muscles there wrought the softest moan from you. You prayed he didn’t hear it and tried hard to be quiet as he continued to pay close attention to that area. The pressure in your loins and lower belly intensified and you found yourself rubbing your thighs together, giving you much needed friction on your… area.

Soft moans let you and when Gyomei noticed the way they quickened he applied more pressure, moving down ever so slightly. If he moved anymore his hands would be rubbing the ass he knew was so plump and so soft. Your moans suddenly seized as your whole body tensed. Gyomei felt your body give the slightest tremble as your breath hitched on a silent cry. He knew exactly what had just happened.

It made his cock twitch and throb painfully.

You couldn't believe it and it left you wanting more.

Gyomei gave you your first orgasm…

 

—-----------------Present--------------------------------

 

The scent of cooked meat brought you back to the past and you looked toward the piece of meat Gyomei was holding to your lips. You reached out a hand to grab it, taking it with a soft “thank you” before putting the piece of meat in your mouth. The taste wasn’t all that great. Bland and gamy. But it was food and you weren't in a position to be picky.

You ate until you were full and you thanked Gyomei for the meal. He nodded and leaned down. Your eyes widened and you leaned back, placing a small hand against his puckered lips.

“I need a bath.” You said in a panic, hoping to distract him.

You needed all your strength, so you could not afford for him to… *pleasure* you again.

He frowned but nodded and stood. As he did so, his tail wrapped around your body and lifted you. You yelped, flailing a bit, before being placed on Gyomei’s shoulder. His tail left you and you lost your balance a bit. Your hand reached out and gripped Gyomei’s horn, using it to stabilize yourself. You found yourself leaning into Gyomei a bit, laying your head upon him and taking in his scent. His scent was slightly different but he still smelled of the Earth. Still smelled like your Gyomei.

Gyomei began to walk deeper into the cave and you frowned. *I wonder where he’s taking me?*

The silence between you two was deafening and you couldn't help but break it.

“Gyomei?”

He grunted in response.

“Why do you keep me here? Why won’t you let me leave?” Your voice held hints of fear and sadness. You just wanted to go home. To get the others and figure out a way to help Gyomei, without killing him. They let that girl Nezuko live so why not Gyomei.

Gyomei’s brows were furrowed and he was silent for a long while. But soon he spoke one word. “Safe.”

Now it was your turn to frown. “What do you mean ‘safe’?”

“Safe. Keep you safe.”

Now, it was time for you to get angry. And angry you were. “You think keeping me trapped in this cave and having your way with me whether I want to or not is keeping me safe?!” You snapped.

He flinched and rubbed the ear you were seated by. No doubt his demon senses amplifying his already keen senses.

Part of you wanted to apologize but another part said to hell with him. Serves him right!

“Safe. Here. With me.” He said. His tone was somber and he tilted his head in your direction.

You glared at him and jumped off his shoulder. He halted as you landed in front of him on shaky legs. Small pebbles dug into your feet and you hissed in pain. You pointed a finger at Gyomei and jabbed it in his hip.

“Keeping me here against my will is NOT keeping me safe!” You growled. “You need to let me go. What do you expect me to do? Just be happy here? Compliant without so much as food, water, or clothes. What am I to just let you do whatever you want with me? Till I die?” As you spoke the reality of your situation hit you hard and you suddenly found it hard to breathe. Your hands pressed against your chest as your heart began to race. The world around you spun and you struggled to stabilize your breathing.

“I’m going to die here…” You said in your panicked state. “I’m going to die here in this cave. Either by starvation or illness.” *Or from Gyomei eating you.* That thought caused you to spiral more and your knees buckled. Gyomei caught you before you hit the ground and he lifted you. Cradling you in one arm, his hand stroked your cheek.

“Calm.” He said softly.

It didn’t work. You continued to hyperventilate as you panicked. Horrible scenarios of your demise racing through your mind.

Gyomei whimpered and began to hurry in the direction he’d been walking. He entered a massive cavern, like a cave within the cave. Before you was a beautiful, crystal clear natural pool with flowers and beautiful green grass growing on the ground around it. You calmed down a bit but not enough to stop your labored breathing.

Gyomei stepped into the water and kept walking until the water was to his chest. He held you carefully in his hands as he submerged your body, leaving only your head above the waterline. The water was cool and it soothed your aching muscles. You slowly began to calm down.

“Deep breaths.”

You listened to Gyomei’s words and took deep slow breaths. Soon you were completely calm, relaxing in the water. You slowly eased out of Gyomei’s hold and swam away from him. You swam to a more shallow part of the pool. One that allowed you to stand. You covered your breasts as you faced Gyomei, now fully aware of your nakedness.

“Thank you.” You said softly.

He nodded and then went under the water. You watched as he swam around, coming up every so often to take a breath. He looked peaceful swimming, and it reminded you of how when he was human, he’d swim to relax himself. You looked away from him and began to wash the dirt and grime from your body. It felt so nice to clean yourself and the water did wonders to relax your sore cunt. You closed your eyes and dunked yourself under the water to wash your hair. You drank some of the cool water as you did so, quenching your thirst.

*So good.*

Your eyes shot open when you felt a presence in front of you and you nearly choked on water when you saw it was Gyomei. He was so close to you, his nose nearly touching yours. Gyomei cupped the back of your head gently, and brought your face to his. His lips pressed against yours and his tongue entered your parted lips. He did not shove his tongue down your throat this time however. His tongue stroked yours as he kissed you with intense passion. Yo felt your body respond eagerly to the kiss, your chest puffing out, your nibbles brushing against his hard chest.

You sighed into the kiss as your arms wrapped around his neck. Your fingers tangled in his hair and tugged, causing a deep rumble to vibrate his chest. The sensation traveled to your nipples and straight to your womanhood. Gyomei wrapped his arms around you, fully encasing your body with his muscled limbs. He pushed up, breaching the water's surface. Your kiss did not break as he walked you to shore and laid you on your back on a bed of flowers.

Gyomei lips left yours to kiss down your neck, to your breasts, sucking both your nipples, before he continued his trek down. As he neared your cunt you parted your legs for him. He growled, turned on by your compliance. His long tongue licked up your folds and you let out a low moan. You didn’t know why you were being so compliant with him all of a sudden. You were just yelling at him not too long ago and now here you were, on your back, legs spread wide for Gyomei.

*Shameful…*

You watched as he pressed his tongue flat against your pussy and gave it another long, slow, lick. You bit your lower lip at the sight. You watched as he purred, his body shuddering at your test before his mouth covered your cunt like he’d done in the forest the day you’d tried to escape. He sucked on you. All of you. And his tongue began to flick rapidly at your little bundle of nerves. It made you gasp as your hips bucked against his mouth. He grumbled, the vibrations causing another wave of pleasure. You couldn't keep your hips still as he gave your small bean wicked tongue lashing, driving you crazy.

Gyomei draped a heavy arm over your waist, forcing your hips back onto the flowers. His other hand moved and you whimpered as he began moved his mouth up a bit, allowing his fingers access to your hole. He pushed two fingers into you, his claws scraping against your g-spot. You cried out in pain and pleasure and your legs widened more, as if begging him for more.

“Gyomie~” You moaned. Your hands gripped the arm he used to hold you down and you looked up the cave ceiling. “Fuck~...”

Gyomei’s tongue containued to flick your clit as he rapid fucked your hole with his fingers. Moans and whimpers left you, paired with “oh fuck!” and “please… please… please…” and “Gyomei!~”. Your head thrashed and your hips tried so desperately to move. To press closer to his mouth.

You felt a pressure begin to build in your lower belly and pussy like before. And like before, it built until you couldn't take it anymore.

A loud scream/moan ripped from your throat as your back arched and legs trembled. Gyomei pulled his fingers out of you and shoved them into your mouth as he licked your pussy clean. You didn’t try to turn your head away, instead you sucked his fingers and licked them. Cleaning them of your wetness. A moan left you and your hands gripped his wrist as he thrusted his fingers in and out of your mouth like he’d done your cunt.

Eventually Gyomei pulled his hand away and moved to sit on his haunches. You watched him closely and that's when you noticed it. Gyomei had a slit on his stomach where his genitalia was supposed to be. It was long, starting from just below his belly button and trailing all the way down to where his balls would’ve been. You frowned but then your eyes widened as, from the slit, emerged a massive cock.

His cock was massive, at least 16in. and had immense girth. The shaft was the same tone as Gyomei, grey, and the tip was a shade of purple. Pre cum leaked from the tip of his cock and dripped onto the flowers beneath him. Your heart raced and you felt yourself begin to panic once more.

Surely he didn’t plan to try and out *THAT* into you? It would break you in half!

To your horror Gyomei reached forward with one hand and picked you up. Due to his size and yours, he was able to grab you by your torso and lift you with one hand, his hand almost fully wrapping around you. You shook your head and began to struggle as hard as you could.

“Gyomei no! Please!” Yes, you’ve always wanted to lose your virginity to Gyomei. Have always wanted to feel him inside you. But not like this. Not with that monster he called a cock.

His tail wrapped around your ankles and lifted your legs up as he rested his cock on your stomach. The tip rested just below your breasts, his pre cum now coating your skin there. His tail slowly winded around your legs, stopping at your calves, causing your legs to squeeze together, thus squeezing his cock with your thighs. He groaned and slowly began to move his hips. He thrust his cock between your thighs, the undersided of this monstrosity rubbing your sensitive clit. You stifled a moan and watched as he fucked your thighs.

You watched as more precum coated your skin, and could feel his cock pulsing. He whimpered, clearly in discomfort. No doubt having built up tension from never seeking a release for himself since he’d first made you cum on his fingers. You watched helplessly as he pulled his cock from in between your thighs and with his free hand, lined the tip up at your entrance.

Tears streamed down your face and you pleaded once more. “Please Gyomei…. Please don’t do this!”

But he didn’t listen. He began to try and push into you, but due to his size and how small your hole was, there was resistance. It hurt so bad. The pain was nearly unbearable. *I can’t imagine how bad it would be if he manages to get inside.*

He huffed and kept pushing, his tip creasing up a bit and his shaft bending slightly as he kept pushing and pushing. Your body tensed up from the pain and you gritted your teeth. Your nails dug into the hand that held you, drawing blood.

You felt a small give as he pushed and your breath hitched in your throat. *No! No! No!* His tip slowly began to push into you, painfully stretching your poor hole. Tears flowed freely and searing hot pain shot through you. It was as if someone had set fire to your cunt and then dumped alcohol on it.

After what seemed like hours, Gyomei had finally managed to get the tip of his cock into your virgin pussy. He stopped pushing and you were thankful. You’d surely die if he’d pushed all of himself into you.

You panted and your body went slack, your pussy desperately trying to adjust to his size. Your eyes were barely open, the ordeal having tired you out greatly.

“G-Gyomei… please… pull it out…” You whimpered, barely above a whisper.

You felt Gyomei begin to pull back, his too gradually leaving you and you nearly shouted with happiness. But your joy was sooner sniffed out when Gyomei stopped, just as his tip was about to leave you. He adjusted himself and then thrusted into you, pushing nearly half of his cock into you.

You’d felt something tear before a warm liquid dropped from your cunt. No doubt blood from your hymen being so brutally torn. You couldn’t even muster up a scream. The pain was that high. All you could do was stare up at the cave ceiling in shock as your body twitched. He had pushed deep into you, way past your cervix, his tip pressing against the walls of your womb. Gyomei gave you no time to adjust. He began to pump his cock in and out of you, showing no mercy as he fucked you.

He growled and whimpered as he fucked you. Your wetness from your orgasm paired with the blood from your hymen provided him with the lube he needed to slide in and out with ease. You gritted your teeth against the pain, praying for it to be over already. You felt his cock apply pressure to your bladder each time he entered you, causing you to get this strong urge to pee. You whined, trying so hard to hold it in, but as the tip of his cock assaulted your insides, you couldn't stop as your body emptied your bladder. You sobbed from embarrassment as you pee all over Gyomei’s fat cock.

With your bladder now empty, it provided Gyomei with more room to push into you, going in another two inches. The pain worsened as your womb was stretched even more, but even as the pain worsened you began to fill small tinges of pleasure. *What?* How could this possibly start to feel… good? But to your amazement, the way his cock stroked your insides made your body tingle with delight and your pussy tightened around him. You felt his cock twitch and his thrusts picked up speed, becoming more frantic.

“Gyomei no please! Not inside!” Your pleas were no use, falling upon deaf ears as he frantically pounded your cunt.

Gyomei let out a booming roar as he slammed into you, fully burying his cock deep inside you. His hips jerked as ropes of cum shot from his cock into you, filling your womb up. You felt your womb begin to expand as he filled you and the base of his cock swelled, forming a knot that trapped him, and his hot seed, inside of you. His tail released your legs and they fell. He moved his hands, one moving to support your ass whilst the other rested on your back. You panted as you looked down and whimpered at the sight of your belly.

Your stomach was swollen, like you were pregnant and there was a soft glow beneath your skin. *Gyomei’s cum… glows?* You huffed and your head fell back as darkness began to close in around you.

 

—-----------------------------------------------

When you next awoke, it was to Gyomei circling your hips on the tip of his cock whilst he was hunched over, sucking on one of your nipples. You felt a strange sensation in your nipple and it made you frown. As Gyomei kept suckling, the strange sensation grew and grew until you felt something... be *pulled* from your breast. You gasped in surprise as the sensation continued. Gyomei's suction pulling a warm liquid from your breast.

*Am-...Am I lactating?*

Gyomei pulled more milk from your breast and it made you inadvertently moan. The way he made your hips swirl on his cock drove you wild and him drinking milk from you did nothing but add coal to the raging flame. You bit your lip to stifle your cry of pleasure as you came, your body trembling as you clenched tight around his tip. He growled and switched to your other nipples, drinking milk from your other breast now. He pulled himself from you, your cunt already missing his cock.

Your womb was still full from his seed, though it wasn’t as bulged out as before. Now instead of a large bump, it was small, barely noticeable. You brushed a hand over it. *Is he trying to breed me?*

You were pulled from your thoughts as something pushed into your cunt, making you groan. You looked and saw Gyomei had just inserted the rattle of his tail into your pussy. He pumped it in and out of you, slowly, pulling soft moans from you. He repositioned you, your back now pressed against his chest as his hands gripped the underside of your knees, holding your legs apart. Because of his massive cock stretching you, his tail slipped in and out of you with ease. It felt so good. You were so sensitive you could already feel yourself about to cum again.

Just as you were about to go over the edge, he pulled his rattle out. You pouted but then your disappointment turned to fear as he pressed the tip of the rattle to your asshole. With how he had you positioned, it allowed for easy access to such a place. You knew you didn’t stand a chance at escaping his hold, so you braced yourself for the inevitable.

You hissed as he pushed the rattle into your ass, your wetness, blood and his cum more than enough lubricant. He had as much difficulty pushing his rattle into your ass like with pushing his cock into your pussy. After another round of agonizing minutes, his rattle was finally buried inside you. It had felt as if your ass would rip as he pushed it into you. So far from what you could tell, there was no tearing.

He pulled the ratte out, which took much effort, making you cry out in pain as he pulled it all the way out with a loud POP, before pushing it back in. Tears streamed down your cheeks as he repeated this action. He kept repeating it until he was able to pump it in and out with ease. Finally, he pulled the rattle out and kept it out. You breathed a sigh of relief.

You heard a fleshy sound and looked down. A gasp left you as a second cock emerged from Gyomei’s slit, joinging the one he’d savageldy fucked you with. This cock was different. Like the other, the shaft was gray, but the tip on this one was green. The tip was also slightly longer and slender and the shaft itself was ribbed.

*What the-*

Gyomei’s tail wrapped around your torso to hold you up as his hands went to grip both of his massive cocks. He turned you to face him and you gave weak protest as Gyomei’s tail lowered you toward his cocks and you whined as the tips pushed against your holes. A soft cry left you as his cocks pushed into you. The purple one resuming its place in your pussy and the other entering your ass and stretching you. You whimpered as he lowered you to the base of both of his cocks, a deep moan leaving his parted lips.

His tail left you and he laid on his back. Your feet were planted on his stomach as you sat on his cocks, his hands holding onto your torso. For a moment all that could be heard was your heavy panting. Soon, he began to move you up and down his cocks, thrusting up into you as he brought you down. Your mind grew hazy as he pumped his massive cocks in and out of your body, your belly bulging painfully each time he went deep inside. Blood, cum and your own wetness mingled together as he fucked you slowly. Your body felt as if it were on fire, pain and pleasure intertwining in a beautiful dance. Gyomei leaned up slightly and drew one of your taut nipples into his mouth and sucked. You felt him draw milk from your breast and the sensation made you shudder.

Gyomei moaned at the taste of your breast milk and you felt a powerful shudder travel through his own body.

“Gyomei…” You moaned, your back arching. You could already feel an orgasm coming, a tight coil forming in your lower belly.

You heard soft mumbling and realized Gyomei was whispering against your breast.

“Y/N… forgive… so good… can’t…” His voice was deep, deeper than before and sounded like a growl. Inhuman. This was the first time you’d heard his voice and it made your holes clench. You reached out, for Gyomei, your arms wrapping around his head and drawing him close to you. You didn’t know what to say. Couldn’t form words. But you wanted to let him know that it was okay. That it wasn’t his fault. Yes at first this whole situation horrified you but now… to hell with everything. Now all you wanted was Gyomei and the pleasure he brought you.

Gyomei’s cocks twitched inside you and his pace quickened. You found yourself meeting him thrust for thrust, riding him as he thrust up into you. He whimpered and moaned, his arms moving to loosely wrap around your body as he sat up. You buried your face against his chest and planted your feet firmly on his thighs as you moved up and down.

“Gyomei… Mmmm… Gyomei! It feels so good. Your cocks are amazing…” Your nails dug into his skin, your body trembling as you neared your climax. You could hear Gyomei mumble what sounded like your own name between growls and his body tensed.

Suddenly, the coil snapped and you screamed with pleasure into Gyomei’s chest, sinking yourself all the way down his cocks. You felt Gyomei’s cocks swell at the base, locking them inside you.

Gyomei’s purple cock pumped gallons of cum into your womb, but another feeling drew your attention. Gyomei’s green cocked pumped what felt like… balls? With each jerk of Gyomei’s hips his green cock laid what you could only assume were eggs deep in your ass. The sensation made you tense as another orgasm tore through you.

“Gyomei…” You cried weakly as your stomach grew in size. Gyomei’s knots kept his eggs and cum in your body, and you could feel his eggs move through you. Suddenly you felt a sharp pain as the eggs made their way into your stomach and a wave of nausea hit you. Your head swam and you sagged against Gyomei. He purred and squeezed you a bit. He nuzzled the top of your head and you heard him mutter one word that made your heart swell.

“Mine.”

His. You were his. Now and forever. You didn’t know what would happen if the demon slayer corp ever found you two. All you knew was that you never wanted to leave Gyomei’s side. Nothing would EVER take him away from you. To hell that he was a demon. You were his and he yours. And that’s all that mattered.
