˚୨୧⋆｡˚ ⋆ — 𝐂𝐎𝐍𝐓𝐀𝐈𝐍𝐒 : afab!reader, denji being a simp, also obsessed with ur tits, cumming inside, unprotected sex

masterlist | chainsaw man masterlist

Denji wouldn’t exactly call himself a cat person per-se but after coming home from a stressful day to see you on the couch in nothing but his shirt that showcased the plump of your breasts yet hid the plush of your body — asking to be unwrapped and ravaged, well, he practically pounced on you.

He couldn’t stop himself from shoving his head underneath that damn shirt, using it as a veil of sorts — hiding the sins that would later follow. He could only imagine from an outsider’s point of view what he’d look like — a mass floating side to side as he rubbed his face back and forth on your stomach as if spreading his scent, claiming you as his.

Soon followed by him pawing at your tits, grabbing at anything he can while he dry humps you, chasing his high as he leaves mark after mark on your once clear skin.

Eventually he’d lift his head from your (his) shirt to gain more control, grabbing your hips in such a hold you know it’ll leave bruises. He’d lift the shirt just above your tits, watching them bounce with every thrust he made after slipping ever so teasingly into your warm and inviting hole.

He’d even let a few mewl’s slip as he watches his slick cock diving in and out of your pussy, only dying out after making his last claim on you - filling you up until you’re practically overflowing.

After using a finger to push his warm cum back where it belonged he’d slowly collapse on top of you, digging and nuzzling his face into the side of your neck as he peppered sweet kisses wherever he could reach.

He’d still never admit that he’s a cat person though.

your fictional significant other always feels conflicted..

sometimes they want to lock you away in a tower somewhere so that you’ll always be safe and protected from the world

and other times they want the whole world to see you, to know you and your greatness—and know that all that greatness belongs to them

Denji with a Codependent gf!

Contents: Denji x f!reader, mdni, Aged up Denji obvs like think college, 1 vaginal sex mention, dissociation and mental illness mention, blood mention once like minor injury, alcohol mention, reader's grandma death mention, reader is a hot mess but denji is sweet!! about 2k word ..

Affectionate is a bit of an understatement. You are clingy. Dependent. You think you couldn’t surivive without Denji, you know you couldn’t. It’s like the world is frozen over but Denji’s this constant fire, the only one in existence, and it’s either stay by his side or die of hypothermia. Denji’s cool with it though, he’s glad he’s able to keep you thawed. And he’s pretty good at it; holding one or both of your hands every second they aren’t already occupied, dropping little words of affirmation, noticing your moods and checking up on you whenever he senses it’s necessary. Denji is highly in tune to your needs somehow, like it's second-nature. It’s funny because he’ll forget big, seemingly basic things all the time like how to boil eggs or what day rent’s due or even his own birthday, but when it comes to you… at some point he became omniscient.

Like there was the first time you went to a party with him, and you were working through some really tough shit mentally. Some girl you had a class with wouldn’t stop talking to you about her dead dog—apparently he was put down just the day before and she was really messed up over it. Denji had stepped out to buy soju, and you were at least 15 minutes into your exhausting consolation efforts, when suddenly the poor girl shrieked and ran to the bathroom, dripping with the sticky contents of another party goer’s drink. Just then Denji reappeared, holding a geranium he plucked from someone’s yard, and you were tucked into his side.

It was a couple hours before you learned of the artful shove Denji threw to orchestrate the drink spill, and when you did you laughed so hard soju came out of your nose.

When you were denied an internship that your professor described as “imperative to advance in your career field” Denji bought you two cake pops and let you paint little flowers on his fingernails.

When you got in a car accident, Denji proposed you spend eight hours and forty five minutes watching rom coms together on his bed. Most of which were subpar by his standards but he didn’t utter a single complaint the whole marathon.

When you had a fever Denji threw on your apron and spent an hour in the kitchen cooking you the most horrible chicken noodle soup you had ever tasted. Then he was gritting his teeth and sinking you both into chilly bath water to try and lower your body temperature (a trick he read on google a few minutes prior). You cried and protested but it worked; you ended up sleeping through the night at a cool ninety eight point six degrees.

When you spilled hot cocoa all over the freshly finished watercolor landscape you’d slaved over for weeks, Denji threw you on your bed and sunk his cock into you over and over till you couldn’t remember the painting you were mourning or why you were sad in the first place.

Every time your world stops denji somehow makes it spin again. Even the day your grandma died. You couldn’t let go of him all night—you would have panicked if someone made you. You laid on top of him while he watched movies (you couldn’t focus on any of them). You straddled his thighs while he ate leftover take out (you weren’t hungry). You sat on the bathroom counter while he peed (you would have sat on his lap while he was shitting, too, if he had to). It spun a little slower at first that day but Denji got it to keep moving.

Today.. Denji’s the one who’s sad. He hasn’t gotten off the carpet where he’s been laying or moved his position in two hours and you’re growing increasingly anxious over it. Denji is the most resilient person you know! If you’re a flower then Denji’s probably an ancient redwood; wind that could knock you down barely registers for him. So you have hardly any experience helping him through mental adversity let alone this depressed, comatose state he’s in and you’re truly at a loss.

You’ve tried everything. Talking to him, cooking for him, poking him—nothing’s stirred a reaction. So laying half on top of him and cuddling is the solution you stick with. If anything, at least it’s helping you calm down. His foggy, half-asleep state honestly scares you so much you would have called a doctor by now if you hadn’t witnessed the cause.

You’d been at the grocery store, Denji was pushing you in the cart and laughing at some dumb joke you made when a grey-haired old man bumped into him. Denji acted like he saw a ghost. The man did a double take before speaking loudly like he was hard of hearing.

“Denji? Is that you, son? Never thought I’d see that face in a place like this. So you’re a city boy now is that right?”

Denji didn’t answer. He just backed away slow like the man was holding him at gunpoint. You climbed clumsily from the cart to grip Denji’s hand.

“Gosh your daddy woulda hated that, wouldn’t he? His only son packing up and abandoning the hometown.. You know you could always come back to work for me. I’ll bet his little house is in ruins by now, you should really pay it some homage.” He was flashing Denji this toothy grin that made your blood boil. You tried stepping in, “Wha-“

The old man acted like he just noticed you, “And who’s this? You found yourself a real looker eh? Didn’t think you had it in you, son. A pretty thing like that oughtta be kept on a tight leash.”

With that Denji punched him. Not as hard as you know he could have, but enough to knock the wind out of the guy. It was like Denji’s mind was working against his body—one of them wanted to let loose and beat the old man bloody but one was frozen in fear or some kind of hesitation. You weren’t sure which instinct was which. Then he was grabbing your wrist and rushing you out of the store, abandoning your groceries and cart and the old man who was wheezing and laughing after getting hit.

He’s been silent and dreamlike ever since then. Like the confrontation reduced his inferno to simmering coals.

“Deeenji. Denji? I’m worried.” You’re whispering by now. No matter the volume you speak, Denji won’t respond. You offer your millionth kiss on the cheek before climbing to your feet. Time to try method two again. You tie on your apron, moving quickly and shakily with anxiety, and set to work. This time maybe you’ll make something sweet instead of the pasta that’s currently sitting cold in its pot. You grab dishes and a pan, willing yourself to slow your clumsy movements despite the racing thoughts.

He’ll get up. He’ll be fine. It’s okay. Denji’s strong. No need to worry. Crepes. Denji never turns down crepes. If I make these he’ll get up. I can make him feel better. Just gotta cut some strawberries. Easy peasy. I can—

You yelp as the bowl you were slicing fruit into falls to the floor, shattering into pieces and interrupting your thoughts. Then there’s blood, fast and hot, pouring from a fresh cut on your palm. Fuuck! Why is nothing going right today? You spin to grab a towel and scream even louder than the first time when you see Denji standing behind you wrinkling his nose.

“Woah, it’s a mess in here. What’re ya—gah!”

Seeing Denji up and about makes you trip right into broken glass with your bare feet, immediately causing a near fall. Denji catches your arm before you can tumble completely over.

Somehow that heroic catch breaks the dam; now you’re stumbling into his chest absolutely sobbing. You couldn’t help Denji when he was literally dissociating for hours but he’ll just waltz into a room and make things better before you even have time to blink. He’ll always save the day, even on days when he’s the one who needs saving.

“Denji! Denji, I’m so glad you’re up. I was really-hic!-really worried!”

“Hey get offa your feet! Damn, yn, sorry I scared you. C’mere.”

Denji turns and bends real low before sliding you onto his back, marching you piggy-back-style to the bathroom. Then you're sitting on the edge of the sink while Denji bandages your hand and picks glass out of your toes. Your stream of tears doesn’t let up the entire process but Denji chooses not to comment while he works. He’s gentle and patient, biting his tongue between sharp teeth while he concentrates on finding each and every shard. You watch him and feel your heart slowly calm at the relief his presence brings.

“Wanna talk about it?” You both know you’re referring to the encounter with the old man at the store.

“…Nah. Probably later I will.”

Denji clinks another piece of glass into the wastebasket. You sniffle and Denji glares at you. “Do you wanna talk about somethin’?”

His prompting results in a fresh wave of tears as you bury your face in your good hand. Denji sighs and stands, pushing your temple into his side and holding it there, rubbing his thumb back and forth on your scalp.

“What’re you such a crybaby for?” He asks gently. You take a while to respond, rubbing your face off slowly with his shirt sleeve.

“Denji, I don- I don’t deserve you at all!”

“Hu-“

“Like-hic!- I hate that you always have to be there for me-hic!-and save me from stuff but I can’t even do one thing to return the favor. Like today you were clearly having such a hard time but-hic!-I couldn’t distract you one bit.”

You lift your head off his shoulder so you can see his face—he’s staring at you with pursed lips and furrowed brows. You bury your face in his side again.

“Baby, your thinking’s all wrong. You save me all the time! Today was weird, don’t take it personal.”

You sniffle again, shaking your head.

“Be serious, Denji. I’m not helpful at all.”

“Hey. ‘M being so serious! You save me by just existin’.”

You huff and shake your head a second time.

“Come on, yn! You know I need you. You’re like… soothing to me I guess. And I like helpin’ you. Seriously! I can’t explain but I… I wanna be helpin’ you. Like all the time! Never wanna be apart.”

You peek up at him again and his thumb stops stroking your head.

“You…”

“Never wanna be apart, yeah. Just wanna… crawl in your skin or somethin’.”

You study his humorless expression while he wipes your tears then licks the salt water off his fingers. You study his messy golden hair and his eye bags and his sparse freckles. His cider-colored stare. His vulnerable honesty. You can’t help but giggle.

“Hey! What’s so funny?”

“I just feel exactly the same way.”

Somehow, even after the raw gooeyness of his previous statement, this is when Denji manages to blush. He smiles his big, pointy smile. You reach to pull him down to your level, still sitting on the sink, where you can easily kiss him. It’s the kind of kiss that heats up your insides in a fuzzy way.

prequel drabble to this link here hang on . also other denji hcs link here

Pls reblog or smth if u like it I’m trying to talk to ppl about csm more !!!

Do you have Asa or any part 2 character's headcanons?

I loooooove the part 2 gang, and I've posted a bunch of hcs for them on Twitter a month ago! I'll copy and paste it all here

Warning, it's mostly Yoshida because my god I'm insane about him and I apologize

-Octopi are intelligent creatures so Yoshida's contract with the octopus devil is for him to get good grades because it doesnt want to work with a dumb human

-Yoshida ONLY drinks iced coffee, he can tolerate room temp but never hot

-Yoshida really likes cold food in general

-As a kid, Asa knew running while holding scissors is bad so she never did it because she knew she'd trip with them, but in grade school she probably tripped and got hurt anyway from a nearby classmate holding scissors

-Yoshida likes lemon lime sodas because I like lemon lime sodas no other reason it's just true

-Nayuta is a selective mute, but she and Denji click so well that he immediately knows if she needs anything even if she doesnt say or sign anything

-As reckless as he is sometimes, Denji is still very good at taking care of Nayuta, he learned a lot from Aki and from taking care of all the dogs. THIS I'm quite sure is basically canon, even just from the small glimpse of them together in ch97

-If CSM took place in modern times, Yoru is SHIT at video games and Asa is average (hi, not part of the original twt thread, I just remembered that csm doesn't take place THAT long ago and that Denji and Power literally bought a video game console with... Aki's money... So yeah the modern times part was a little dumb of me, but it still applies to some of the hcs ahead)

-Denji spams buttons in fighting games and Yoshida has combos memorized, but somehow he still loses to Denji sometimes

-Yuko is better than all of them and is probably a speedrunning champion

-If all four (five w yoru) of them played games together, Denji and Asa would be at each other's throats while Yoshida and Yuko silently keep playing and win in the end

-Yoru:"I WANT TO KEEP PLAYING!"

Asa:"YORU IT'S BEEN HOURS, IT'S MY TURN TO PLAY ALREADY"

-Remember the doom & acnh thing back then? Yeah Yoru is the one buying acnh and Yuko is the one buying doom

-Yoshida is a rhythm gamer and has spent hundreds of hours on his favs, BUT HE REFUSES TO TRY OSU.

-Denji unironically likes cbat

-Yuko would secretly be one of those popular vocaloid producers that make songs with really dark themes

-Asa listens to her songs a lot without knowing it's Yuko

-Oopsie I just made a fanfic prompt by accident lol feel free to steal the idea

That's the original thread! Here's a couple more hcs I have though, mostly just lgbtq hcs:

-Yuko is nonbinary (in the same way she can't understand people, she can't understand gender roles and all that dumb shit cishets push)

-Related to that last part, Yuko is autistic! It was genuinely my first thought when I read the "I don't understand people" line in 105, I love her so dearly (also I'm also a nonbinary autistic so I'm projecting a little)

-Yoshida is gay and grey aromantic (grayromantic?? Forgot the term) (Also projecting except I'm bi instead of gay, u can tell I love projecting onto my scrimblos)

-Yukoasa are bi4les! Asa is bi but is sapphic leaning after the interaction that is ch104 JSJSKFJDJ she really thought man, men aren't worth it and just visited yuko

-Asa is transfem!! Idk I just saw the flashbacks she had and how she had short hair at one point and I was like hmm and my transfem moots agreed (That post blew up a little actually and some people genuinely thought I was weird or that I was stereotyping cause of the short hair, so I don't talk about this hc that often. I genuinely would've headcanoned her as transfem before I even saw the short hair though, I love hitting csm characters with the transification beam.)

-Speaking of, Yoshida is transmasc! He's a reincarnation of Togata from Fire Punch that was able to successfully transition (socially at least), and he binds! This is one of my fav hcs cause god I love Togata and Yoshida's eerieness in part 1 is really EXTREMELY similar to Togata, and they both have really similar features like black eyes and hair, the fringe between their eyes, the mole under their lip, AND THE WAY THEY SMILE??? I genuinely no joke think Yoshida was meant to be a nod to Togata back when Fujimoto drew him in part 1

-Back to the videogames thing, Asa would be 1st in Mario Kart then fuck up last minute right before she reaches the finish line, and she ends up in last place. My girl trips at the worst time even in video games 💀

Okaaaay brain empty now, hope you enjoyed all these hcs!!

Can I request Reze gf head cannons?

Reze girlfriend headcanons !

a/n : i replied so late omg I’M SO SORRY ANON 😭

— Secretly Sweet

Despite her tough exterior and assassin background, Reze would have moments where her softer, more vulnerable side shows. She might surprise you with small acts of affection when you're least expecting them, like making you coffee in the morning or sending you a random, caring text.

— Protective, but in a Low-Key Way

Reze, being the type to handle dangerous situations, would have a protective nature. She wouldn’t be overly clingy, but would subtly ensure you're safe. Whether it’s walking on the side closer to the street or subtly watching your back when you’re out together, she’d always be aware of your surroundings.

— Playful Teasing

She’d have a bit of a mischievous side, teasing you playfully but never crossing the line. Maybe she'd act cool and aloof sometimes, just to see how you react, but deep down, she enjoys the fun banter and getting you to smile.

— Dark Humor

Given her past and line of work, Reze would likely have a bit of a dark sense of humor. She’d make jokes that are a bit morbid, but somehow make them charming and funny. You’d learn to appreciate her wit, even if it sometimes catches you off guard.

— Quiet Affection in Public

She’s not the type to be overly affectionate in public but would express her care in more understated ways—like gently brushing your hand, fixing your collar, or standing close to you when walking. In private, she’d open up a lot more.

— Good at Keeping Secrets

Reze would definitely have a mysterious vibe, and there’d always be a sense that she’s holding back a little. But instead of being frustrating, it’d keep the relationship intriguing. She’d reveal bits of herself slowly, and you’d always want to learn more.

— Loves Small Adventures

She wouldn’t be the type to want grand, extravagant dates. Instead, she’d enjoy quieter, more spontaneous adventures—like a late-night walk through the city, a secret picnic in a hidden spot, or finding the perfect secluded place to watch the stars.

— Emotionally Guarded

At first, she might be emotionally distant, but as she starts trusting you, you’d see her let her guard down. Reze might struggle to talk about her feelings, but she’d show them through actions. When she does open up, it would be meaningful.

— A Duality of Softness and Strength

There’d always be a contrast with Reze—on the outside, she’s confident, dangerous, and independent, but she craves moments of normalcy and intimacy where she can be herself without worrying about her dangerous life.
