Pairings - Yuuji Itadori x Reader x Ryomen Sukuna
Synopsis - Ever since Yuuji moved away to Tokyo, you've been noticing some odd changes from him, it's almost as if...he was becoming another person all together.
Theme - Monster by Imagine Dragons
A/N - An idea hit me in the head while I was working and I wanted to try this out so badly with both Yuuji and Sukuna! A concept of 'What if the vessel wasn't just the vessel?'. The vessel would eventually merged with the being to become something new altogether, and I thought...yes. why the heck not. This is gonna be a long one, So let's hop right it! Because I really like this idea, theres a good chance this is going to be either split up into parts or I'm gonna keep visiting this every now and then.

All he wanted was to keep those he cared about safe. Lying to you at the time seemed like a good idea, especially since you weren't tied into the mystical world he was now tied to, and he didn't want you too. But now, perhaps he should've told you everything.
About the finger, about the school, and...
You couldn't exactly remember why you originally said yes to the pink haired boy when he asked you to join his occult club activities that night. Maybe it was because of the fact you have nothing really better to do, or maybe because traveling through a forest of possible gruesome death seemed the most attractive thing to you at the time, yet you an Yuuji grew close together that night. Truth be told, walking through those woods during the dead of night was actually creepier than you thought but he was there by your side to comfort you the entire time, holding your hand while cracking a few jokes every now and then to calm your nerves.
"You're not scared? You seem so..well calm?" You asked, looking up at Yuuji with furrowed brows as he just smiled down at you. "Nah, not really. It's just darker and a few trees are around. Not really anything scary, right?" He said, rubbing the back of his neck while chuckling.
Maybe it was because of the warmth of his hands wrapped around your own or how comforting the presence he gave off was to you but it was probably then that your feelings for Yuuji began to grow.
"What you're going to Tokyo?" You questioned, watching Yuuji prepared a few boxes to pack his things. "Yeah, transferring schools. I'm, um .. I'm recieving a sports scholarship at a school there." Placing a few more of things away was when he finally turned to see you, clearly upset over just now being told this. Sure, you should've been happy to see your best friend be able to leave to accomplish more out of his life but it was the thought of him leaving you here that hurt the most. When he saw your face and the conflicted look on it, Yuuji stepped over towards you before wrapping his arms around your waist and pulling you in your embrace.
"I'm sorry, Y/N. I just—" before he could finish his sentence, you stood up on your toes and wrapped your arms around his neck and simply smiled to him. "You don't have to say a thing, Yuuji, I'm happy for you. Just promise me that you'll stay safe out there for me, 'kay?"
Your words alone reminded him why he had to leave, why he had to go and leave you here. It was to keep you safe, safe from curses and safe from the curse lying dormant inside of him now. "R-right...Thank you, Y/N"
The school days were quiet once when Yuuji transferred schools. Sadly enough, the occult club had to disband after he left due to them not having enough members with Iguchi still hospitalized. Now it just seemed..boring without him there but he still seemed to have brighten your day with the photos he would send you every day of the bright city lights and bustling streets. His little messages and calls always well timed to reassure you that just because you aren't blocks away from each other anymore doesn't mean you won't still be friends.
So far, you've became pretty happy with Yuuji and how he's able to come so far in Tokyo. He speaks greatly about his sensei and his new classmates known as Fushiguro and Kugasaki, who from the sound of it, are a bit of a handle but great friends who still treat him well. Every week when he had his day off, he would spend time on video call to talk to you and even show you cool things that he either found around the city or around the school's campus.
Tonight however..he was late. Sure, it didn't bother you really if he was punctual or on time since this was Yuuji we were talking about here but there was a tad bit of worry lingering in your head. Soon enough, as soon as that ugly feeling of worry and doubt began to surface, Yuuji's icon appeared on the screen on the laptop as it began to ring to which you quickly opened.
"Yuuji, hey— oh my god, your face." You said right away, gasping a little at the cuts and bruises littered not only on his face but from the looks of it, his arms and shoulders too. Has he been fighting? "What? Oh, oh! These! Yeah, Fushiguro and Gojou-Sensei kinda roughen me up a little today during training but it's no sweat, really! Barely feel a thing," Yuuji tried to give you a reassuring smile while patting his right shoulder only to wince a little in pain from the impact of the pat.
"First the weird scars on your face, now bruises? Dude, I get that this is a sports thing but don't you think it's a little extreme?"
Hearing the worry in your voice, Yuuji rubbed the back of his neck with his left hand nervously as he tried to think of a way to reassure you until a deep voice came from that same hand, chuckling softly.
"What's this? A woman talking to the brat...? How amusing." Sukuna.
Hearing the voice, Yuuji instantly flinched and lowered his arms out of the camera's view. Panic shot through his body as you stared at the screen with a raised brow. "Oh, is someone there with you now? Didn't know you had a roommate."
Oh good, you didn't see him. It wasn't as if he was afraid of you meeting Sukuna, he was afraid of telling you the truth about everything. About how he was now a vessel for ancient being, how he was studying cursed energy and jujutsu, how he died yet came back to life..dumping so much on you with the chance that you might never speak to him again out of fear, out of disgust. That you stop being his friend, and that he would never..he would never—
"Yuuji?" Tapping the screen a little on your laptop as it shook the camera, he soon stared back at you and laughed nervously. "O-oh right, he's only here for a little bit of time, so I figured what's really the point in telling you"
"Really now? Could've swore I was here to stay with you forever. You could at least introduce me to your friend here." Sukuna felt a great amusement watching Yuuji squirm just to keep you in the dark. Yuuji quickly began stammering on his words, throwing you off as he made a quick excuse to leave the call early. Before you could even say a single word, he clicked ended the facetime before sighing to himself and leaning back against his chair.
"...What is the point in keeping me hidden? We are practically one now, me as you and you as me, Brat." Sukuna said, his mouth now appearing on the left side of his cheek with the eyelid opening to stare up at the boy. "Are you scared of me paying your little toy a visit? Young and no doubt a virgin, I could have some fun with her—" Yuuji quickly slapped a hand against the mouth in attempt to hush the curse only for Sukuna to migrate to the hand.
"I won't let that happen, Sukuna." Yuuji said, frowning as he heard the curse chuckle. He didn't like the sound of how he described his bond to the soul sleeping inside of him, how they were one in the same. Shaking his head, the boy tried to reassure himself that he was nothing like Sukuna and simply went to turn off the lights and sleep on it. The last thing he heard before slumber took him were the ominous words of Sukuna,
"You'll see I was right soon enough, brat..."
A week later, Yuuji came back home to visit you. It was one of the days where the school allowed their students a break from their studies and classes and so he wanted to spend it with you as a surprise. And indeed you were surprised. When you had rushed downstairs, you did so wearing only a red sleeved t-shirt that the pink haired male might have left behind with a pair of gray shorts, and so when you opened the door to see the cheery face of your best friend well...it may have left you a bit flustered.
"Hey, Y/—" you quickly shut the door in his face, collapsing on your knees as you felt your cheeks beginning to burn. 'Why of all days, Itadori?!' You thought to yourself as she slowly stood back up and cracked the door open to see Yuuji's baffled face. He looked like a puppy..a sad puppy who was just kicked off his owner's bed and it broke you. Before long, he was now in your house and sitting in the living room couch while you were in the kitchen preparing tea. Your father was currently away on business while god knows what your mother was..it was just the two of you.
As you prepared tea on the kettle, Yuuji couldn't help but look at the shirt you were wearing as a small pink blush was lightly spreading on his cheeks. In a way, it filled him with a strange feeling seeing you walking around in something of his, seeing you wearing his shirt made him..prideful. didn't help with how short your shorts were either, it was practically hugging onto your as—
"So, it's just you? Dude, you should've told me you were coming! I would've been more prepared..I barely have any snacks or anything here right now." You grumbled, snapping his attention away to listen to what you were saying. "Hey, no worries, Y/N. Honestly, I'm just hungry for something else..." that last part through him off as he covered his mouth. That wasn't his voice. No, it was but that wasn't him speaking.
As he turned his head to the side to the balcony door, there the boy saw it in his reflection. The eye of Sukuna staring right back at him, causing him to quickly cover the eye.
"Huh? Alright, well what are you hungry for? Theres probably some ramen around here someone or we could just go out to a place to eat if you want.." you questioned, back turned away from him as you began to take the now whistling kettle off the stove. No, he couldn't deal with this now, not while you were only feet away from him. Yet the more he watched you in the reflection, the more he saw your curves in those pretty little shorts or your braless breasts bounce with ease under his stolen shirt...
Shaking his head, Yuuji soon stood up from the couch and placed on his jacket. "I'm sorry, N/N, But I have to go—"
"Sorry, u-um, Gojou-Sensei said something came up and I have to go back! I'm sorry but I'll make it up to you— I promise!" Before you could even protest, he was already out of the door and gone. As he left, you could've swore you saw an eye on his cheek where one of his scars were but that was impossible, right?
He honestly had no idea where he was going to run off to but the boy knew that if Sukuna had a chance to take over and you were in front of him, would've hurt you or worse. Seeing your disappointed face yet again almost shattered his heart completely and when Yuuji finally came to a halt, he found himself beside a small stream and sighed. This was all for the best. It was to keep you safe, or so he kept telling himself.
"Damn, to think you would actually run away when she was begging for you to take her there. What a wimp.." Sukuka said, mouth manifesting on Yuuji's neck as his eye looks up at frowning boy. "Its not often you get an open invitation from a woman. If I was in control, I would've taken her then and there and ram my co‐" Yuuji quickly slapped a hand over the mouth as a faint blush appeared on his cheeks, him now thinking back to you and how pretty you looked wearing his shirt. "S-shut up. Don't go saying such gross crap."
"You know you feel the same. I can see that she affects you even now judging by the sight of your pants. You wanted to stuff her with your seed just as much as I did." Sukuna said, the mouth now on his hand. Much to Yuuji's surprise, his dark brown eyes quickly shot down to his pants and just as Sukuna said, there was a raging boner standing up at attention. Swallowing his guilt, he tried to cover it only for his pinky finger to slowly graze the fabric and giving his cock a small jolt. The boy hissed a little and quickly placed his hands to his side.
"I-i..I just.." "No need to be embarrassed. That girl isn't anything typically special but just seeing her, seeing her ass in such revealing clothing. Women of this era must be extremely dirty~" Sukuna chuckled "and hearing your thoughts, you certainly surprised me, Brat..." the more Sukuna spoke, the more Yuuji thought back to you. Seeing your breasts and ass was truthfully hot, even if you weren't exactly his type, he still found you beautiful. Slowly without him even noticing, his hand slowly motioned for his cock once more and in the silence of the forest, Yuuji Itadori thought only of you during his time in pleasure.
It wasn't until later on into the night that Yuuji had finally texted you back, saying he would back tomorrow to make things up with you. Sure, it did cheer you up that he would be back but the way he was acting lately made you feel like something was wrong. If you ever asked, he would change the subject or just smile at you awkwardly as if admitting to hiding something but you won't force him tell you what was wrong. When He was ready, he would tell you for sure and you'll wait for however long he wanted.
"N/N, Everything alright?" Yuuji asked, gaining your attention as you snapped back to the present and out of your thoughts. Looking around, you found yourself staring ahead at a bag of popcorn and the large bright ights of a ferris wheel constantly in motion. That's right, the local fairgrounds, Yuuji had wanted to go one more time before he returned back to Tokyo and since you always liked the food here, you of course said yes. "O-oh, yeah! I'm fine. Just looking ahead at the wheel. Remember last time we were here some kid ended up puking on Sasaki from a cart above us?"
"Haha! Yeah, she smelled of salty tuna for weeks afterwards and it left a stain on her uniform" He laughed, staring at the wheel as he thought about the memory. As you stared at him and watch his smile, it had then reassured you that this was still your best friend and you smiled back. For a moment, the two of you were having a blast at the small fair, playing some of the games set up by the booths (and being turned away after Yuuji broke a few with his strength..) it felt like old times all over again. "Wanna play another game or play at bumper carts? We still have some time to kill before you gotta go back?" You asked, carrying some of the plushie prizes the two of you (mainly Yuuji) earned, you looked over to your side and saw a cotton candy display before your attention turns back to Yuuji, The two of you decided just for a moment to sit down at a small metal bench to rest your feet for a moment
Seeing the display, an idea popped up in his head and the words of Gojou appeared in his mind. 'You want advice on how to swoon a girl? Well take small hints when she gives them to you, if her eyes are lingering on something then that's probably a sign she wants it—'. Seeing as how you kept looking up at the cotton candy, he thought this might have been his chance and sat down his own plushies. Without saying a word, Yuuji got up and walked over to the stand, leaving you there by the table alone with your horde of plush creatures.
Seeing you seating there at the bench by yourself, a group of punks who looked to be close to your age strolled up to you, two of them taking a seat on each side of you while the third one was standing right behind you. "Fine evening, isn't it, love. What's a sweet little thing like you doing here by yourself, you looking for some fun?" The purple haired male said on your left side, lowering his shades as he stared noticeably at your chest. "Actually, I'm here with a friend and this seat is for him so if you could jus—" "oh a 'friend'? But I don't see this friend now, so maybe you could tag along with us back to our place and we'll show you a fun time." The punk behind you said, his hands now pressed firmly on both of your shoulders as he leaned in a bit closer to you, causing you to flinch at his touch. "I, um.."
Turning your head back to in front of you, you saw Yuuji there holding a blue and pink cotton candy stick and face emotionles. "N/N, huh? That's a cute name. This your friend, N/N?" The purple haired punk said, chuckling while rising from his seat "....." Yuuji remained silent for a bit as he stared off at the hands touching you, gripping onto your shoulder and clearly making you uncomfortable. He was typically known for being a calm guy but see this angered him beyond words.
'You see what they're doing to your woman, brat? You're just going to let it happen..?' Yuuji heard the inner words of Sukuna in his head, his eyes dart away from you to the guy standing in front of him, smirking as he touch the cotton candy from the pink haired boy's hand and taking a large bite of the webby treat. "This doesnt have to get rough, all you need to do is walk away and we'll show N/N-chan here a good time she'll never forget." He said, licking his tongue over his lips.
As Yuuji's lips parted, he heard a groan coming from you as you squirmed in the other guys hold with the second punk was now leaning into your neck. Seeing your frown of discomfort, they way they were touching what was rightful his , All he needed to hear were those small words from Sukuna.
'They're touching your woman, they're hurting her. Finish.. them.. off.'
Yuuji stood there for a moment, remaining silent as he lowered his hand, a shadow now cast over his face. Opening one of your eyes as you squirm in the punk's hold, you saw something that made your heart almost stop beating altogether. That smile on his face, that malevolent smile and empty eyes as he held onto the purple haired Male's now broken arm.
The next thing was a blur. The screams of your harassers echoed around you and you heard a wet sound looping over and over again as well as hard thuds. Opening your eyes, you saw it. Two of the thugs bloodied and bruised as their limbs were bent in ways you couldn't imagine, one of them dangling up above you on a tree branch while the other one was limp inside of the cotton candy stand. Looking around for the third one, you saw him behind held against one of the food stands while Yuuji was there gripping his hand over the punk's neck. You couldn't exactly show him any mercy and yet Yuuji was clearly taking things too far, even when the guy tried to beg for mercy and claw his way out of your friend's hold, all Yuuji did was stand there with a grin you've never seen before. It wasnt one of his innocent smiles or mischievous grins, no, it was one of pure sadism. "P-please stop, I'm sorry..I'm sorry.." "you didn't stop when she wanted you too, So why should I?" Yuuji tilted his head to the side a little, chuckling a little as his grip tightened and the man gasped out for air "you'll pay for what you did. You'll all fucking pay..."
The air in your chest almost stopped filling your lungs completely as you watch this. That wasn't the Yuuji you knew, he would've never went this far just to prove a point! Slowly taking a step forward and then another and then slowly speeding up, you reached out and held onto the arm Yuuji was holding the punk up with. "Yuuji, stop it! You'll kill him if you keep this up!" You yelled only to feel a blow strike your face and send you tumbling back a few feet, causing you to scream out in pain. "Stay out of this." Was all he said until freezing and slowly turning back to see what he had done.
Crimson was spilling from your nose onto your shirt and it was gushing out by the bucket to which you quickly covered as you stared up at Yuuji with teary eyes. Regret instantly overwhelmed him as he dropped the thug and slowly reached over to you, his senses coming back to him. "N/N?" He questioned, almost checking to see if you were alright but you backed away as he stepped over to you. What has he done..? Why did he..? He watched you slowly back away with each step, fear in your bright (E/C) eyes and it broke him. "Hey, w-what's wrong? I was only trying to protect them from you, you don't have to be scared."
As people began to crowd in, brought in by the noise of fighting and your scream, Yuuji hand ghosted over the skin of yourself shoulder and you flinched. You flinched at his touch..So many feelings began to overwhelm him that he didn't notice the look of horror in your eyes as you watched what thought were scars slowly twitch and open up, revealing bright red eyes staring directly at you.
"They were going to hurt you," 'She's scared of you now after all you've done' "I saved you! They won't touch you like that again!" 'She sees you for what you are, brat.' "I just wanted to keep you safe!" With each yell, Yuuji watched as you grew more and more scared, the people around all of you terrified as they watched and some even grabbing whatever they could that could be a weapon. Gripping his head as he felt an intense pain through his skull, it was then he noticed..how small you looked as he towered over you. When did you get so small? He thought to himself, bending down to grab you when he saw his arm.
His nails were a dark purple shade, sharper and three black markings were on his wrist. Turning his head a little to one of the booth's and staring into the window was when the truth hit Yuuji hard. His body was different and taller now for some reason and Sukuna's markings were slowly appearing over his face. He was..slipping?
"Y-yuuji, what the hell is happening to you.." he heard you whisper yet before he could respond, there was the sharp pain of something blunt hitting his shoulder. Looking to his feet, he saw a medium sized rock and there another and another. The people were launching what they could at him, yelling at him to leave the girl alone and to leave. Yelling for his death, calling him a monster, calling him a curse. He stared at you for a moment, seeing how now tears leaking from your eyes and Yuuji stepped away before fleeing.
"Yuuji, wait!!" He heard your frantic yell from behind him but it didn't slow him down as he kept running further into the distance and leaving you behind. Your yells becoming drowned out by the mad laughter of Sukuna echoing in his mind.
No, he didn't want this at all. The day was meant to go differently, it was meant to be just the two of you having fun together and end with the ferris wheel and him finally telling you that he...
Thunder crackled outside of the decrepit shrine the boy had taken shelter in, rain pouring outside by the gallons. As he watched the raindrops in silence, Yuuji saw how the scenery slowly began to shift around him as the sky became more malevolent and the cold concrete he was sitting on now a pool of crimson water with piles on top of piles of bones surrounded him. The memories of the fairground echoed in his mind over and over again on loop of him hitting you and your look of fear haunting him, causing his eyes to water.
"Aw, are you going to cry, brat..?"
Yuuji remained silent as he waited for Sukuna to appear at any moment, yet he never came, only his voice lingered around him. "This is all of your fault.." Yuuji whispered, staring off into the rain. "My fault? I don't understand. If I recall, you were to one who eat my finger. You were the one who signed up for being my vessel, everything that has been done was all you..I merely watched from here."
"Bullshit! You made me hurt her..you made me like this!" Yuuji screamed out, flashes of who he did to those thugs showing through his mind, "You made me hurt them!"
"...No, that was all you. You can blame me all you want but I felt what you felt, saw what you saw and you loved every second of that fight. Whipping those who displease you in place, kicking the asses of the men who touched what was yours. Gotta say, made me tear up watching everything unfold" Hear the curse's chuckle echo around in the shrine, Yuuji quickly stood up and yelled out for Sukuna to show himself, only for him to collapse on his knees when feeling an sharp pain in his torso.
"No need to show myself, I'm already with you as close as I can."
Gritting his teeth in pain it was then that Yuuji saw his reflection staring back at him in the water, grinning ear to ear with malice in those sharp fangs.
"You see , Brat, becoming my vessel didn't just mean I was trapped inside of you..no no..You would slowly become me. Your small soul means shit compared to mine and it will be swallowed whole by me. I just needed us to be bound for some time and you would be mine..."
As the reflection spoke to him, Yuuji screamed out in pain as he felt his bones inside of him crack and twist as if they were rearranging themselves. His stomach felt as if it was being cut open entirely as the flesh began to slowly pull apart while tearing open the yellow hoodie in the process, the meat of his torso was forced open as a tongue lulled out and licked his abs like they were lips. The sides of his waist felt as if someone was taking a pair of axes and were merely swinging it down as flesh began to bubble through and bones formed one by one until two new pair of arms were fully shaped. Taking a deep breath, Yuuji slowly chuckled as one of his hands reached up to his head and gripped it and the others wrapped around his waist.
"You should be honoured, Yuuji. You get the privilege of becoming one with me, my power is now yours and yours mine." His lips, against his will, began to speak the words of Sukuna as they formed into a forced grin. "N-no..I haven't told her yet. I haven't told N/N that I love—"
Once when he blinked, Yuuji found himself no longer in the shrine but sitting inside of his desk in his old desk with you standing beside him. Seeing you before him, safe and smiling at him, the boy quickly stood up and wrapped his arms around you which took you for surprise in the process but you simply allowed him to let it all out when you hugged him back. "Well hello to you too, welcome back to earth, how was your trip to space..?" You said, chuckling before feeling something wet on your shoulders. His tears.
"Y/N..I..I'm sorry. I'm so sorry for everything, I should've told you everything. I should'nt have hit you. I just wanted to protect you because...because...I love you!" His words surprised you but you simply smile. "I love you too, Yuuji."
Staring back down at the reflection before him of the boy hugging onto you tightly as he weeped, dark brown eyes shift to that of a bright velvet shade. Sukuna chuckled while stretching out his newly formed body. How good it felt to be back in control, to have actual flesh again and to see this brand new world all to himself. Sure, his power was not what it used to be but he would regain all of his fingers soon enough. As his domain faded away and he found himself back in the decrepit old shrine, he smirked to himself while debating his next order of business.
"Y/N L/N...Maybe I should do this body a favor and seize you for my own."
He wouldn't answer any of your calls or texts. No one has heard or seen of him but now there was a witch hunt for your best friend. As you laid in your dimly lit bedroom with bandages over your nose, you stared down at your phone anxiously awaiting something from Yuuji.
Hearing the sound of your phone vibrating, you quickly shot up from the covers an grabbed the phone, unlocking it right away and placing it to your ear.
"Hello?" There was nothing but silence on the other end, the soft howling of the wind being the other thing you could really make out. "Hello..?"
"N/N.." your heart practically stopped for a moment but you felt almost a wave of relief hearing his voice on the other line. "Oh thank god, Yuuji..Are you ok—" "N/N, open the window." Was all he said before then line went dead and you were left sitting there baffled. Did he make it back to your house? Slowly crawling out of the bed and slipping on your bedroom slippers, you walked over towards the window and moved the blinds down only a little to peep outside. Standing there in your backyard, shirtless and with his hands in his pockets was Yuuji, seemingly back to normal and everything. There were not increased height, no weird markings, he looked fine and apart of you wondered if it was just the force of his punch that made you see him change. No..because everyone else saw his appearance too.
Taking a deep breath, you lifted up the blinds and unlatched the window. The second that it was free and opened up, Yuuji had jumped above onto the roof and crawled inside to your room. "Y-yuuji, you have a lot of explaining to do— Whoa, whoa!" You took a step back cautiously but he soon grabbed ahold of your wrist and pulled you close to his chest, wrapping his arms around your waist and resting his head in the crook of your neck. "I know I do, but first I just want to say I'm sorry to you, Y/N. I never meant to hurt you.." he said, whispering in a soft tone as his hold on you tighten a bit.
"I'm leaving here after tonight but I just had to see you to tell you that I..I love you. I love you, Y/N" Taken back by his words, you felt yourself being pushed onto your bed and watched as the boy loomed over you before crawling onto the mattress.
He loved you. Those words practically made your heart skipped over so many times that you were positive that you had stopped breathing. "Let me come with you, Yuuji." You said, reaching up to his face and caressing his cheeks, "I don't know what's happening but you can trust me. I won't let you go through this alone and I'll always be here with you."
He didn't say much after that. All he did was lower his head a little until your lips were merely inches away from each other before he pressed them together. The sensation you felt was one like fireworks. Those butterflies in your stomach exploding and multiplying over and over again as you felt his tongue licking your bottom lip but you pulled away before he could fully explore your mouth.
"Always..? So you will always stay with me, N/N?" He whispered, head dipping down to your neck as he left a trail of kisses down your warm skin until he kissed the base of your throat. "Yeah..I will." "Do you swear..?" His hands began to grip your hips, running the tips of his fingers against your clothed thighs while he began to press his own hips to your own.
"I-I swear.." you said, staring up at Yuuji with a small smile. He stared at you for a moment, smiling down at you before sitting up, his large hand covering the upper half of his face.
"That's all I need to make you mine." Sliding his hand upwards was when you saw it. Those spare eyes once again on Yuuji's cheeks, staring at you as if it you were nothing but glass. That sincere smile that calmed your soul became a mischievous grin, showing the sharpened fangs he now had. You watched as those pitch blackp markings began to spread over his skin and yet the moment you sat up, two fully grown arms pinned you down onto the mattress. "Almost as naive as the brat himself but I suppose there is some charm to the naivete of a woman. Makes it easier to influence, to change.." 'Yuuji' said, dipping his head down to your ear before biting down on the lobe of it. You gasped out, squirming in his hold.
"Let me go, Yuuji! I don't know what's going on but I want to help! Just let me help you!" You yelled out to him but soon silenced yourself as you noticed the scenery of your bedroom changing. All of your furniture began to disappear one by one as a red hue began to spread around the two of you
In the blink of an eye, you were taken to Sukuna's innate domain. The water that replaced the softness of your bed now causing your back to soaked and your hair now spread out and floating in the depths. "Yell all you want but that brat can't hear you anymore. Gone forever in a dream that will never come true, but I promise I will keep you company in his stead. By the time I am done with you, will forget all about him. All you'll want is me, all you'll ever need is me. The name Ryomen Sukuna will burned into your soul and you'll learn to worship me, N/N..."
With a single swing, the soft yet wet cotton fabric of your shirt and shorts was torn off of you with ease and revealed your now exposed flesh to the cold. Sukuna stared down at them, his tongue licked over his long and sharp fangs as his eyes motioned down to your folds. His hand traveled down your thighs before his finger swiped against the outer circle of your lips yet he looked displeased from what he felt. "Dry as a drought but that's fine. I'll be fucking you regardless" he said, his index finger slowly pushing inside of your virgin cunt causing you to gasp out for air and arch your back. "You tighten just now, dirty whore...Did you often fantasise Yuuji stuffing his cock inside of you...?" he whispered into your ear intimately, he kissed the bottom of your ear and moved onto your neck, sucking until he found the soft spot that made you inhale deeply.
Sukuna sucked on your neck while constantly kept inserting his finger in you, pumping in and out, eventually adding a second digit. He curled his fingers and caused you let out a faint moan as his finger crept closer to your sweet spot over and over. It was too much, you thought as he bit down onto your soft skin, and you were feeling so good from it so far and it made you ashamed. this demon, this thing was in your best friend's body and now he was using it to currently assault your body but the feeling of it all was too good. You had to keep your eyes shut for looking up at Sukuna tugged at your heart as all you saw was Yuuji.
"Oh you are loving this..." parting from your neck,he looked pleased seeing the angry red hickey left behind.
"I-im not...I'm not..." A moan escaped your lips, feeling something wet replace his fingers. Lifting your head, you saw a mouth on the palm of his hand and its tongue gently licking the nub of your clit almost like a lollipop. "Feels good, doesn't it, N/N..?" His tone was nothing less than mocking, the mouth taking ahold of one of your lips with its teeth causing you to scream out. "I said, it feels good doesnt it? Speak when your master is speaking to you. "
"Y-yes! It feels amazing!" You tasted so sweet on his tongue, circling your clit, lapping at your clenching entrance, kissing your folds. "A-Ah~" You whimper when he folds your legs to your chest, He takes another nip at your clit, as he listened to your hushed whines. Your moans were music to his ears, yet what he wanted from you was his name. The thought of his former vessel's love screaming his name turned him on, the thought of keeping you only fueling the flames. It was harder and harder for him to contain hisself when you're drowning in the pleasure of his mouth licking and sucking at your sloppy pussy.
"I'll take you as mine. You'd like that wouldn't you? Being the woman of the king of curses, waiting for me to return to fill you to the brim." sweat felt like it was pooling out of your body from the attention he was giving to on your clit. Your bucking hips were a clear sign that you were close and so, he pulled his hand away.
"You don't get to come yet. You're only allowed to when you're milking my cock."
The things he did to were things no man has ever done before. Scratches and cuts littered your flesh and bruises were on your sore ass and stomach. There a few times to where you had even blacked out from the amount of pleasure he had given you..
Now you found yourself with you riding his swollen cock as he stared up at you with satisfied eyes, grunting while large hands were pressed against your abused breasts as his hips pumped up into your leaking cunt. Your head felt like it was spinning as you screamed out, orgasm crashing hard as your cunt tightened around his shaft.
As you felt his throbbing cock inside of you, his hand grabbed ahold of your chin and your lips made contact. Sukuna only pulled away when he silently cursed, his seed releasing inside of you for what felt like the billionth time. Taking a deep breath, he stayed inside of your warm hole, not wanting a single drop to spill and kissed your cheek.
Fucking you only assured his choice of keeping you as he own. Sukuna was going to original kill you while taking Yuuji's appearance after taking you but holding you close like this as you soon became limp (no doubt exhausted), your warmth against his own and staring down at your cum stained face..it made something inside him feel strange.
A weakness no doubt, but one at the moment that could keep him entertained. Combing a loose strand of hair behind your ears, Sukuna chuckled.
"From this day forth, you will be my bride. Consider yourself lucky..."
