... oh my gosh... you know how people "joke" calling people with glasses "four eyes"?
Yeah, just thought about how Sukuna literally has four eyes and Jin wears glasses. I mean they were already wearing the same outfit combo so yeah, I can see how Jin could be his twin.

Hey gamers, I woke up and immediately started writing this. Four hours later and here I am with this brain love fest, hopefully you like it as much as I do! The new episode really lit something inside me that I thought would simmer down at some point. Cross-posted to Ao3 under the same name, shared to twitter at kenjakusbrain, comment or reblog if you also can't stop thinking about the brain or liked the fic.
The sound of your front door opening and closing roused you from the nap you hadn’t intended to take. You had a feeling tonight might be one of the nights Kenjaku would choose to visit you, but you were never entirely sure unless he’d mentioned it directly. Though you were informed enough about his plans in the days leading up to the 31st to know that he would be in Kyoto on the 19th. Kyoto was where he’d requested you stay ever since they’d begun using that pitiful student as an informant. To make sure he didn’t let anything out, since Kenjaku couldn’t be sure that the boy wouldn’t come to his senses and break the vow they’d taken, he’d placed you here to keep a watchful eye.
You had wanted to stay up, hoping you’d be right about Kenjaku stopping by, but you’d been far too exhausted. Near constant surveillance of the student’s hideout and his robot body simultaneously had you relieved when you watched Kenjaku and Mahito approach the building you knew the student to be in. Finished with your part of this mission, you’d accidentally let yourself fall asleep.
Kenjaku barely gave you the chance to greet him before hoisting your body into the air. A shocked sound left your throat as he pressed an excited kiss to your lips. Through your surprise you kissed back, feeling his tongue slip into your mouth to press against your own. The intensity of the kiss surprised you, Kenjaku was a passionate man but it had been years since you’d seen him this riled up after a single preparation mission.
Large hands manipulated your body, Kenjaku keeping you pressed against him while moving you into a standing position. As your feet touched the ground you felt his lips pull away from yours, leaving you trying to catch the breath he stole from your lungs.
Looking up at him clearly for the first time since this leg of your mission started, you were again shocked to see such manic glee across his features. Kenjaku smiled down at you as if you were a celebratory meal he couldn’t wait to dig into.
“Things went that well?” You asked, hoping he’d fill you in before you got too carried away.
The smile on his face widened, hands squeezing your hips tightly before he leaned back down to kiss you once again. Less pure passion and more of a firm press of his lips against yours. Not that you minded, affection and Kenjaku didn’t always go hand in hand, so you accepted it whenever it was offered.
“They couldn’t have gone better. Watching Mahito evolve so rapidly under pressure is just astounding. And the boy’s use of a simple domain was eye opening, it’s something the newer generation of sorcerers nearly have mastered!” Kenjaku’s voice much more animated than normal as he spoke. His excitement was palpable, you could feel his fingers digging into your hips as he spoke. “It won’t be long now, the 31st is just around the corner.”
While you hadn’t known Kenjaku as long as others like Uraume, you’d been with him for quite some time now. This was the first time his plan had progressed so far. Everything was just falling into place around you, all of his work for the past century blending together, as if it was fated for him to finally succeed. The last time he was this excited, he’d just acquired his current vessel, another important piece to his plan.
“Soon we’ll be able to move past this and onto your main goal,” You said, bringing your hand up to his chest and pushing him back toward the couch he lifted you from. Seeing Kenjaku this worked up had quickly brought you out of whatever tiredness had taken over your body, his energy was magnetic and you couldn’t help but want to celebrate with him.
The smile on his face turned into a smirk as he allowed you to push him back. There had been points in working together that you were stronger than the vessel he inhabited, even if it wasn’t the case with his current form, you still knew just what he wanted in times like this. Before pushing him down onto the couch, you untied the golden fabric at his waist, slipping it off of him and tossing it to the side. While you didn’t dislike his vessel’s robes, they had proved to be inconvenient in the past at times like these.
“Impatient are we? What if I had just come to debrief you on the mission?” Kenjaku teased, using this moment to untie the belt that kept the rest of his robes closed. You took your chance to help him, reaching up and slipping the heavy material off his shoulders, not caring that it had fallen to the ground at your feet. It was something for the two of you to care about later.
The warm skin of his chest now bare under your fingers, you pushed him back again, forcing him down onto the couch. His hands left your hips briefly as you moved in to straddle his strong thighs. Settling on his lap you felt his hands return to your body, kneading the flesh of your ass. A soft moan caught in your throat at the feeling of him handling you roughly.
Slipping your fingers into his long hair and gripping against his scalp, you pulled roughly, forcing him to look up at you. The smirk on his face was still there but the look in his eyes wasn’t quite as manic as before, dark eyes full of lust now stared up at you.
“I know you, Kenjaku. I know what you want after a job well done,” You whispered, hands flexing in his hair. Leaning down you pressed another open mouthed kiss against his smirking lips. He met your kiss with a soft moan as he let your tongue into his mouth without resistance.
The kiss quickly turned desperate as he ground his hips against your core, the position leaving you open on top of him. You could feel his thick cock growing in his pants, rubbing against the soft shorts you fell asleep in. The thin barriers adding more friction to his movements, you knew it felt good for the both of you.
Sucking at his tongue, you pressed your hips down against his, feeling a rush of pleasure fill your body. It had been long enough since the two of you were able to be intimate like this. Slowly you pulled your face back, breaking the passionate kiss for a moment. You were panting slightly, looking down to take in just how much you'd affected him.
Kenjaku’s lips were flush from all the kisses, mouth slightly open as you watched his tongue trace along his lips. Like he was still trying to taste you. His cheeks were lightly dusted as well, you couldn’t wait to make him even more flushed.
Your eyes were drawn higher, to his forehead, where you could see the stitches straining to keep shut. All the pressure you applied to his hair had done exactly what you’d hoped for. Kenjaku, the real Kenjaku, was barely visible to you through the stitches, fluid leaking out and beginning to slip down his face. You felt your heart beat faster at the thought of what you were going to do to him.
Not wasting any time, you ran your tongue gently across the seam in his forehead. The juices thick against your tongue as you brought them into your mouth greedily. You could feel his muscles tense under the attention, nails digging into your hips. After swallowing all the leaking fluid, you slipped your tongue against the straining stitches. Pressing open mouthed kisses to the seam, you could hear his breathing become more shallow with each movement you made.
One of his hands left your backside, quickly reaching up to tug at the stitching that kept him from you. Your grip in his hair loosened as you felt him remove the top of his head. It was a sight that you never fully got used to, you had always expected there to be much more blood. He gently moved the top of his vessel’s head further down the couch and out of your way.
The soft flesh of his brain, the real Kenjaku, was now exposed to you. Fluid leaking down his face again but you were too focused on the delectable tissue before you to bother licking it all clean. Leaning back in, you kissed softly at the brain, allowing your lips to travel around the teeth in the middle.
Kenjaku moaned at the feeling of your lips grazing his most intimate parts. Every press of your lips or pass of your tongue on his brain sent waves of pleasure throughout his entire body.
As you felt his hand return to your ass, you let your tongue slip into the open mouth at the center of his brain. The teeth nipped lightly at your lip before allowing you in, the kiss much messier than the ones you’d shared with his lips. You could feel his juices making a mess on your cheeks, you could feel an ache growing in your core at the thought of how you were making him feel.
“I can’t wait much longer,” Kenjaku said, voice trembling with pleasure as he spoke. You knew what he meant, you knew you were just as wet as he was in this moment. He slipped a hand between your bodies and teasingly slid his fingers against your pussy through the clothing.
Instead of taking off your shorts or stopping you to undress, you felt him rip the thin material, ruining the shorts and exposing you to him. Kenjaku’s thick fingers quickly dipped into your wet folds, teasingly rubbing against your sensitive clit before he pushed two fingers into your aching hole.
You moaned into his brain mouth at the feeling, the thick fingers filling you up perfectly. Kenjaku’s teeth nipped at the tip of your tongue as you broke the kiss. You couldn’t help but focus on the feeling of his fingers inside of you, rocking back and forth you felt them crook inside you just right and brush up against that spongy spot that pulled another moan from your body.
Lost in the pleasure Kenjaku was bringing you, you let yourself get lost in his soft tissue. What started as soft licks and kisses to the folds on his brain had devolved into sloppy kisses. Your tongue gently pressing broad, wet strokes across every part you could reach.
Kenjaku’s moans were beginning to sound as desperate as he tried to focus on stretching your pussy. He wanted to draw this out, to tease you on his fingers and make you beg for his cock. That wasn’t going to happen tonight, you forced his hand the moment your tongue slipped in between his stitches. Kenjaku could feel his cock straining against his pants and leaking into the material he needed to bury himself deep inside you the way you buried your tongue into his brain.
You moaned against the teeth on his brain, tongue tracing them and begging for another kiss. Kenjaku’s fingers inside you felt too good, it was distracting you from your goal of making him feel more.
As quickly as they’d entered you though, Kenjaku pulled his fingers out of your pussy, leaving you to press your hips down onto nothing. You whined at the loss, the mouth finally opening for you and allowing you to kiss your way back inside of him.
You could feel Kenjaku repositioning himself as he used the hand still on your ass to hold you still. Too lost in the way your tongue felt inside his soft tissue to pay attention to what he was doing.
You felt the thick head of his cock rubbing against your pussy, slipping through your folds to rub against your clit. Moaning into the kiss you could feel his cock quickly become soaked in your juices, sliding through your folds with practiced ease. It seemed like Kenjaku was content to just grind against you and tease you both.
Putting one hand on his shoulder to balance, you reached down in between your bodies. Your hand finding his now soaking wet cock and guiding it back toward your aching hole. Kenjaku let you take the lead again, waiting for you to slip the tip of his cock inside you before moving again.
As soon as he felt your tight pussy around his cock, he knew he wouldn’t be able to last. You eased yourself down, taking every inch slowly so as to not hurt yourself. The kiss you had been sharing with Kenjaku’s brain paused because of how much you were panting, teeth still nipping at your lips to continue.
Once you felt Kenjaku bottom out in your pussy, you took a moment to savor the feeling of him inside you. His thick cock stretched you so perfectly, it felt so good. Your mind dizzy at how you could feel him throbbing with want inside of you.
A hand of his pressed against your cheek, pulling you out of your pleasure drunk state for a moment. You looked down at him, his face as flush as you knew yours was and his eyes brimming with tears. You were worried for a second until you remembered just how overwhelming it was for him to have his brain touched this much. Perhaps you had made more of a mess out of him than you realized already.
The hand pulled you down, lips meeting in a messy kiss. You moaned at the feeling, different than kissing his brain mouth, softer and less control. You could taste his brain juice still, it turned you on more to know that he was tasting himself as well.
Kenjaku gripped your hips tightly with both hands before lifting you up, letting just the head of his cock stay in your pussy. You sucked at his tongue, wanting desperately for him to fill you back up. He lowered you, stuffing you half full with his cock. It wasn’t enough.
“Kenjaku please, stop teasing,” You begged, though you had been the one doing most of the teasing tonight this was too much for you.
Without wasting a moment, Kenjaku quickly began bouncing you on his cock, forcing you to take him all the way inside with each powerful thrust. The scream that left your mouth was cut off by his lips on yours. Keeping you quiet as he fucked you, the last thing you needed was to draw any neighbors attention.
Soon your moans had died down and turned into whimpering mixed in with desperate kisses. The feeling of Kenjaku’s thick cock splitting you in half made your toes curl and eyes roll back. He was perfect for you, hitting every spot and rubbing the most sensitive parts of your tight pussy just right.
As close as he had been, Kenjaku needed more to get him back to that edge. Fucking up into your tight pussy as he manipulated your body to ride him felt amazing, but he wanted to feel as fucked out as you did. Breaking the kiss, Kenjaku’s lips kissed their way down, biting at your neck hard enough to bruise. He could feel your pussy clench around him at the violent act, you loved it almost as much as he did. It wasn’t enough though.
Your pleasured moaning was interrupted by soft, wet folds brushing up against your lips. Kenjaku had positioned the two of you the way you had been before, his brain right in front of you. You didn’t need to be told what to do, long licks at the soft tissue made Kenjaku’s cock throb inside you.
Keeping his pace as steady as he could, Kenjaku felt a rush of intense pleasure overtake him as you lavished his brain with licks and kisses. Not only did it make each thrust feel ten times better, his entire body felt like it was on fire. He hadn’t felt this sensitive in a long time, biting at his own lip to keep some of his needy sounds inside.
The thrusts inside you turned erratic quickly, Kenjaku’s even pace falling apart as you let your tongue past his teeth and into his brain mouth again. The kiss was sloppier than before, his juices and your saliva coating your chin as you got lost in him. Every thrust had you moaning into the mouth, you could barely keep up with it.
You could feel Kenjaku’s thighs trembling under you, both of you so lost in pleasure that all you wanted to do was push each other over the edge.
Nails biting into your skin, you could feel Kenjaku’s grip on you getting tighter with each violent thrust of his hips. Fucking up into your pussy blindly, the feeling of Kenjaku so deep inside of your pussy finally pushed you to your limit. You felt yourself let go, pussy squeezing him as if begging him to finish.
The tight heat of you coming all over his cock was more than enough to push Kenjaku over the edge, stuffing you full of his cock before releasing deep inside your pussy. His thrusts slowed enough to allow you a chance to breathe, while he still fucked you both through your shared orgasms.
Your tongue slid out of his brain mouth and teased around the folds, enjoying the taste and soft feel of the tissue. A gasping moan tore from Kenjaku’s throat, it was too much for him. His hands left your hips, leaving his cock buried inside of you just to fly up and pull your lips down to meet his.
The kiss was languid, both of you came much harder than you expected. When you pulled back from the kiss, you could see his beautiful fucked out face. Brain fluid and your saliva on his flushed cheeks, you were sure you looked just as flushed and sticky.
Reaching over, Kenjaku picked up the top of his head and put it back on. Quickly sewing it back into place as you watched. You never got tired of watching his deft fingers apply the stitching. With his scalp back in place Kenjaku’s hands returned to your ass, lifting you into the air as he stood. His spent cock slipped from you as he carried you into your bedroom.
“If I’m still here when you wake up, we can talk about what happens next in my plans. For now, let’s rest,” Kenjaku said, kissing your messy cheek as he crossed the threshold of your room.
Can I please request Sukuna and reader picking up their child from preschool? It can be anything, fluff or angst, its up to you!
Love your work and keep it up <33
thank you for requesting and i'm so very sorry that this took a billion years to complete... i just now finally thought of an intriguing way to do this request <3
some warnings: fem!reader, major character death, ooc sukuna, major angst, modern AU, sukuna and reader have a daughter
good things never really last.
well, at least that's what sukuna believed before he came across you. you and your delicate expressions and equally as delicate affection and warmth, which seemed to wrap around him constantly, even when he tried to avoid you at the beginning of all this, all because of his own uncertainty and his rather skeptical outlooks on the concept of love.
he's always been self-centered-- so the idea of his life becoming centered around anyone else but himself, frankly, scared him a little bit.
but, putting that aside...
a high pitched, overjoyed squeal rings out from inside the daycare centre, and a little girl comes running into your open arms, embracing you with the overflowing energy that little children always tend to have. you lift her up with ease, smiling as she giggles from the gesture.
"mommy!" she says, nuzzling her soft, tiny face against yours without much care for being gentle. someone else trails in from behind, feeling a little left out from this reunion.
"aren't you forgetting someone here, princess?"
sukuna also makes his entrance into the centre, walking towards the both of you. your tiny daughter gasps, and flails her arms out towards the big man.
"daddy!! you're here too?!"
"that i am, sweetheart. happy to see me?" he takes her away from you, holding her as gently as possible with his large hands.
"uh huh," she nods with enthusiasm.
"of course you do. my little girl."
the sukuna of the past would've never fathomed having a future like this, where he'd be handling a child of all things with such care. it's really different when they're your own flesh and blood. he's adored her like no one else. ah- well- no one else but you, that is.
he carries her to the car, while you take your daughter's bag from the daycare teacher, who waves you off with a couple of words of goodbye.
the ride home is nothing short of cosy and cheerful, with the happy singing of your little girl coming from the backseats, and the laughs from you as you listen to the way she mispronounces a lot of the words in the song. sukuna drives wordlessly, with a gentle smile on his face.
the skies happened to be so clear that day, with not a speck of a cloud being sighted within it.
some time after arriving home, you began to languidly start your work in the kitchen, preparing dinner that also turned out even better tasting than usual, that particular night. you always felt the happiest, when sukuna praised your cooking, especially as someone who you knew had very high standards when it came to food.
and miraculously, once dinner was all finished and your daughter was all dressed up ready for bedtime, she managed to fall asleep a lot faster than most evenings, leaving you and sukuna with quite a bit of...freetime.
you lay on the mattress under his sultry gaze, as he undresses you carefully as though he were unwrapping a present, trailing soft kisses down the side of your neck. you're as beautiful as the day he first met you. this was the most perfect end to the most perfect day in his life.
too perfect.
...
he should have been suspicious, with the way things were getting so blissful in his life-- his life that had previously been so rocky and turbulent.
was this supposed to be punishment for his sins? for all his arrogance and selfishness? the heavens decided to grace him with the feeling of genuine love and its reciprocation, only to then tear it away from his hands once he'd started to take it for granted.
...it was an unforeseen accident. could've happened to anybody. why did it have to be you?
good things never last.
sukuna drops the home phone immediately upon hearing the news, and hurriedly packs a small bag for his daughter. he drops her off to her friend's house, who is a long term neighbour of theirs. then makes a beeline towards the hospital, speeding past every red light that dared to try and stop him.
yet, that was all for naught, as by the time he'd arrived to your bed at the hospital, you had already taken your last breath, and said your final words. which he couldn't hear for himself.
'please tell them that i love them'. that was apparently all you tried to say. sukuna is made to sign some documents on your passing, and shortly after, they give him some time to spend with your lifeless body. he is then sent home.
he arrives to see some mail that had been slipped in through the front door. notifications of fines, for crossing red lights multiple times and going against speed limits. nothing but a reminder of his failure.
he tears the letters into pieces, and sits himself down on a chair, where he hangs his head in silence, without bothering to turn the lights on in the house.
and all of a sudden, he becomes so very busy, in the following weeks.
caring for his daughter alone. preparing for your funeral. accepting your death.
grief is such a strange, and horrible experience. all this love he has for you. where is it supposed to go now?
the night after your funeral, he's sitting alone at the dining table once again. he can't stand the bedroom. not when it's become only his now, and no longer yours as well. sukuna hasn't slept well in a while.
small footsteps resound against the floorboards, and he looks up to see his daughter standing meekly a distance away from him.
"what's wrong? had a bad dream?" he asks, with the most gentle voice he can muster in his current condition.
"...no. i just had a dream about mommy," she confesses tearfully.
"why can't she just come back? i miss her."
too young to understand the concept of death.
"oh, sweetheart... i miss her too."
she begins to cry, and he gets up to comfort her, as if the one needing the most comfort right now isn't himself.
they huddle and sleep together that night, in attempts to replicate your warmth. the warmth of a mother. and the warmth of a wife.
-
since then, a part of sukuna seemed to change back into his older self, where he cared less for others and remained disinterested in most things that life offered him. he decided not to care about anything or anyone, other than himself and of course, his darling daughter. your gift to him. the only thing keeping him grounded.
he never finds a new lover, nor does he harbour any desires to seek for one, despite the encouragement from others.
you keep appearing in his dreams every now and then. every night before bed, he hopes to see you again, and is disappointed in the mornings where he wakes up with the realisation that it didn't happen.
years and years pass, and while he ages like fine wine, so does his little girl, who becomes not so little anymore. they still share the best bond that a father and daughter could ever have.
but eventually, she finds her own path in life and leaves the house to pursue her own dreams, even getting married to start her own family.
though they still regularly contact each other, sukuna's abode becomes sorrowfully quiet without her presence around. though he's proud as a father, this solitude only deepens his longing for you, like the sensation of slowly sinking towards the bottom of the ocean floor.
good things never last.
though, it's not until a few more years later, that he passes away rather peacefully of old age.
his soul feels light and airy. he feels calm, despite being aware that he's passed on into the afterlife. the bodily discomforts of aging is non-existent in this place.
he's walking towards the bright light, where he assumes he's supposed to go, and realises that there's a figure standing towards the end of it. sukuna already knows who it is, and his walking begins to speed up.
and with each step, his time rewinds.
"look at you. still all pretty and pristine, unlike me with my abhorrent wrinkles," sukuna comments with a chuckle in his voice.
"what are you talking about? you're still as handsome as ever."
as you grab his hand, your touch shifts his appearance... and sukuna reverts back to the time when he glimmered the most vibrantly - the days before you died, the days of his brilliant twenties. he stares at his own hand, where the creases in his skin have disappeared completely.
rejoicing, he pulls you in for a tight embrace, as he can now feel your body against his.
"you did so well. our little girl grew up so beautifully," you tell him with your sweet voice, hands placed against his broad back.
"of course. she's none other than our daughter, after all," he replies with confidence, as he presses his face against the locks of your hair, enjoying your familiar scent.
your bright smile turns to something more sorrowful, and you step back a bit to come face-to-face with him.
"and... you never found someone else. you never remarried."
"because I never intended to look for another. You were the first and last," sukuna tells you matter-of-factly.
"wasn't it lonely?"
"...terribly. but you're here now, so it was worth enduring after all."
you laugh, and it sounds exactly the same as it did all those years before. the memories he had of you, the ones that he held onto so tightly as to not forget, until his very last breath.
"that makes me selfishly happy. i shouldn't be, for your sake, but I am."
"then why don't you give me a kiss? for all my hard effort."
he leans in, like how he'd always done whenever you appeared in his dreams at night.
except this time, your lips actually reach his, instead of disappearing away, like a fleeting memory.
good things may never last for long, but misfortune certainly doesn't last forever, either.
