#serizawa katsuya smut

[thistletisle]

Men who whimper when you tease them, sucking on the tip of their cock, he begs for you to make him cum and that he needs it so bad.

You find this quite adorable and finally end up giving him what he wants, slowly, you sink onto his cock while he lets out a moan and grabs your hips.

“F-fuck h-ha…! O-oh my god.. I love you- I love your pussy s-so much..!”

♡˗ˏ✎*ೃ˚ content warnings : nsfw. serizawa katsuya x gn!reader. blowjob (serizawa receiving). not proofread soz

sucking serizawa off in his computer chair in the dead of night. he's a struggle to take in, all 8 inches of him but you love the tingle, get drunk off the way his fat girth stretches your mouth to the limits. but you love most the noises he makes. huffs for breath, unashamed of the rumbling volume as you sink your nose further and further, your tongue pressed flat and resting as it should in the back of your throat; you're a serizawa cock sucking pro after all.

because just how many nights has he woken you up, dribbles of sweat under his curly tendrils, with a panted plea, "i'm sorry, i really need your mouth right now." because how many opportunities has he given you to train your gag reflex until you had the most perfectly tight mouth for him to fuck into?

Intro + Masterlist 💞

Preferably do read through all of this! I’d appreciate it!

Intro (Masterlist under the cut)

Heyo! I’m Alex, I joined tumblr a good while ago, but never really had the courage to post much. Until now!

My pronouns are He/Him, and my account is absolutely a safe space for LGBTQ+ folks!

For safety, I won’t share my age. Regardless, I’ll block any weird dms.

On the topic of DMs, any messages or asks simply saying “hi” might not be answered 😭 they make me anxious.

Smut

Proship

Anything political

(I will add to this as time passes.)

Disclaimers:

If I find a request uncomfortable to fulfill, I will reject it.

If some things have certain disclaimers (such as TF2 with ‘no ships’), it is because I’m not comfortable exploring writing with that specific topic for the fandom.

For characters, like Hobie, I may refuse various topics for them for various reasons. For Hobie specifically, his age is unconfirmed and constantly debated.

Do keep in mind that I’m a student with a job and family, and some requests may take a while. I tend to revise my stories multiple times over 😭.

Update on this section: I've graduated! Currently job searching like crazy and also prepping for college, however tryna get back into the swing of things now that I have some free time.

Of course, if something isn't listed here, feel free to ask! There's a multitude of fandoms I find myself interested in.

However, feel free to ask if I can write something! I’ll almost always say yes.

[puppywawa]

Hello everyone !! My name is AD, 18 and my pronouns are she/her!! I am a multi muse, filipino roleplayer/writer!! I am quite new to the rp community in tumblr so please understand that I'm inexperienced. This blog is mostly to find more reigen rp partners who can giggle and ramble with me about serirei Currently, i am into mp100!! i love the anime with all my heart, have finished the manga and currently consuming anything reigen and serizawa related LOL My current muses right now are Serizawa Katsuya and Kageyama Ritsu; I am more experienced with Serizawa but i also do love writing Ritsu! I have a few set of rules i would also like to make as a seperate post but as of right now, i will be writing them here so please take the time to read them in case you ever want to write or just simply chat with me about anything!!

-----

• Main muses are Serizawa and Ritsu!

• I usually write on discord and prefer to have a server for all the rps. I draw, write and speed out ideas a LOT btw so please be warned. I’m a rambler and I really love Serirei a lot and want to interact with people who love it or just generally love mp100 as much as I do!

• I write mostly romance for adult characters ( between Reigen and Serizawa ) but I can indulge with some Ritshou but I will not write anything nsfw of them; the most I can do for them is soft feelings and pecks but other than that, I am not comfortable writing anything else between the two. I am, however— very indulgent with Serirei ( as long as I can have Serizawa smothering love towards reigen ) and will bend myself for the ship.

• I can word vomit and write long replies a lot- it’s how I usually write so please don’t feel pressured to write the same length as me!! • Via discord rp; PLEASE tell me if I write something that ever makes you uncomfortable- I can edit it out and such, I don’t mind as long as everyone feels safe.

• I’m really biased with Serizawa. I can be ooc with him a bit so please do not attack me if you have any problems with my mischaracterization of him. I am only here to have fun and write, to indulge myself with people.

• I’m also a little bit biased with ships. Im very serirei but I’m open to ideas like dimple x serizawa as long as my rp partner is indulged!

• I have school and responsibilities from my parents so if I don’t answer, I’m probs asleep, working or @ school • Lasty; Dont be shy with interacting with me! I am always happy to make mutuals and friends around here! I would love to answer any questions- either in character or just questions you would want to know about me!! So please dont be shy :D &lt;333 ------

• FOR NSFW STUFF; PLEASE STOP HERE WHEN YOU FEEL UNCOMFORTABLE WITH THE TOPIC. THANK YOU AGAIN.

• I usually just write doms/tops and I can get pretty hardcore with smut writing— please tell me if there is any kinks or stuff in smut you don’t want to read! I also like dark topics but absolutely no adult/kid. That shit is not allowed in my rp blog. I’m very into some dark serizawa content and such but if that’s not your cup of tea, please avoid the " DARK TOPIC // " tag. • I only write nsfw of characters and ocs; cant do erp via me. I will only do them via discord as I am way too shy to write them publicly. PLEASE NOTE THOUGH that i will not just write on a whim. I will be able to make headcanons and such but i need to get to know you and feel comfortable enough to write it. I do write suggestive content here and there so my tags here will be " NSFW // " in case you ever want to avoid it.

[letstalkaboutfandomsbaby]

Serizawa looks like the kind of guy who always cums quickly, pussy so good you make him feel like his first time every time.

Fuuuuuuuuck y-yea, i can see that 🥴 bet he cums from the simplest foreplay. You give him any kind of attention and he's about to bust. Looks like the kind of guy who loves pussy jobs and wants to suffocate between thighs but never asks for that stuff bc he's shy. You have to put a cockring on him just so he can last long enough for you to be satisfied not like he's complaining tho 💦

[glavielepj02]

Serizawa has a gift for reigen✨✨🥀

[arabaka]

♡˗ˏ✎*ೃ˚ content warnings : nsfw. afab!reader. voyeurism. power dynamics.

Meeting in a shabby hotel room, getting absolutely railed and being the next entry in a long list of reasons why mattress’ coils are so loud and squeaky. Your legs spread eagle, Reigen fucks you hard and deep against the bed with fists cuffed around your ankles as he looks at you like you’re the only person in the room.

Because you aren’t. Serizawa is there too, fisting his cock with reckless abandon and haphazard strokes as he sits in the corner. Serizawa’s teeth dig into his bottom lip and drain it of its color while he watches your sweet face contort on every thrust, every sharp slam of Reigen’s weight into your crying heat. Your tight hole gushes out splash after splash of your erotic essence; you just never seem to stop. That seems to make him want to grip himself a little tighter, rub and roll his foreskin a little harder… Pretend that it’s your much smaller hands touching him, imagine just how much smaller they’d look in the presence of his fat and fleshy cock. 

Reigen seems to pour into you every ounce of the erotic passion he feels from having his subordinate watch the two of you fuck. Like he’s showing him, I’m the reason she feels this way. Look at how easily drool seeps out of the corner of her mouth. Pay attention to the way her voice gets high and breathless when I angle her hips just right, press my cock right up against her ravished center. 

Your feet bob helplessly in the air. Reigen is nothing but strained groans and heavy pants as he fucks you dumb on his cock. The sex smell is dense in the air. You’ve been at it for so long. Your sex flutters, your eyes rolling back as the overstimulation starts to build up in your nerves. 

You can barely see Reigen through the dim lighting and with a tear-glossed gaze but you can see Serizawa just fine, his ragged expression cast in perfectly as the light from the hotel room’s bathroom bleeds in. And his look, with iris hollow with carnal desire, tells you that none of you are stopping anytime soon.

WIP Roll Call | 7.10.21

I’ve gotten a few new followers after @httptamaki​ shared my fic, so I want to give a list and brief descriptions of some of the fics I’m working on right now! I can’t promise a timeline or word count, all of these will be as long as they need to be.

Also, all of these stories are subject to change. The pairings will stay the same, but the ways to get there might change :)

Attack on Titan

Levi x GN!Reader

I forgot about this one! I have five full pages of notes for a vast overarching story involving Levi meeting someone during the four years they're investigating Marley. Honestly, I'm excited to revisit it!! I wouldn't say this is imminent by any means, but it's my most fleshed-out long fic idea at the moment. All I will say is that the Reader will be a bookstore owner in Marley. I will include smut, but the story won't revolve around it.

Avatar: The Last Airbender

Hama Fic (Unnamed)

So, in my opinion, the way they wrote Hama as a villain did her dirty. So, I'm writing a fic where she gets brought home to live her twilight years in the place she was taken from, that she gave up everything to protect. This story will take a lot to write because I want her progression to be realistic. I'm indigenous and have elders who survived residential schools. I'm also looking at Holocaust survivors who sought indiscriminate vengeance after the war ended. It'll be a very angsty story because fanfic lets folks explore the more gritty things that studios like Nickelodeon can't. Hama's story is a part of that, for me.

Demon Slayer

Haganezuka Hotaru x GN!Reader

Notes I have for this one have a scenario where you live in the swordsmith village but earn your keep by making pottery for people to use and sell. Since you and Haganezuka are both busy with your crafts, you have a more spontaneous arrangement.

Uzui Tengen x Wives x GN!Reader

Another shameless self-insert. I love fics that include Tengen's wives! You get caught in a storm and need to take refuge at their estate, which was the nearest safe place you could find. The storm will be devastating, requiring you to stay longer than you anticipated. Shenanigans unfold as you slowly realize they have a lifestyle that you've never seen before...but are intrigued by.

Legend of Korra

Sozin's Comet's Return

I've been thinking about and planning this fic for like two years. It's set 30 years after the end of Korra, making her about 40 when the comet returns. It'll be a gen fic about an event with some intrigue, but mostly I want to have fun with worldbuilding and think about how things have changed 30 years after the portals opened. One point of inspiration I'm taking for this is that I was a small child when we got the internet at home, and now in my 30's, it's in every aspect of our daily lives. So, I'm considering ways to show how the portal being open has changed the region decades after.

Mob Psycho 100

Serizawa Katsuya x GN!Reader

There aren't many Mob Psycho 100 characters I want to write for, but Serizawa makes the cut! I am trying out Plottr with this one, using their mystery outline to see how it feels to use tools like that for writing. I want to have a romance plot with the Reader and Serizawa, but it won't be the only point of interest. There's not a lot hashed out yet, but I know I want Serizawa to lose his virginity to the Reader.

My Hero Academia

Aizawa x Trans!Hizashi x GN!Reader

A steamy one-shot with Erasermic. I've been thinking of what I want to do with these two. Y'all realize your feelings, and things progress from there. I might do some poly dynamic vibes or introduce the idea. Depending on how much fun I have with it, it might either be a long fic or multi-chapter. No promises!

Chimera Eros: Chapter 3

(Amajiki Tamaki x GN!Reader)

The next iteration of the Chimera Eros series, I just finished the outline for the chapter, and it's gonna be a fun one :) More soft sweet praise from the Reader and cute subby Amajiki, as usual.

Sub!Hawks x GN!Reader

I've posted about this before, and I have a complete outline for it. You and Hawks have a scene you like to play out when you find the time. The Reader has a somnophilia kink, so you challenge Hawks' stealth skills to creampie you in your sleep. If he wakes you up, there will be punishment - and you're a light sleeper.

Outlaw Star

Aisha Clan-Clan x Sub!GN!Reader

A dom/sub scenario where Aisha controls who you sleep with and makes special requests of you while you do it (such as bringing her creampies when she finds a suitable human). Aisha is the namesake of this blog, so I want to do her justice in anything I write for her!

Yu Yu Hakusho

Botan x Keiko x Yusuke

I have a whole page of filthy notes for this one, and I honestly forgot about it until today, LOL. Botan and Keiko have some fun while Yusuke is away, and both feel guilty and confess. After some contemplation, he presents an idea for them to make it up to him. This will be ABSOLUTE FILTH.

Jin x Toya x AFAB!Reader

This one is also a one-shot idea. These are a couple of my favorite good boys from Yu Yu Hakusho, so I want to give them some love!! I would like for the Reader to get DP'd by them, so I'll go with F or AFAB rather than GN for this.

Kurama Horror Fic (Unnamed)

This is one I've posted about on here before. Still, I want to write a horror story involving Kurama's relationship with his mother. Excerpts from other posts about it:

"My concept is...what if Kurama wasn't supposed to save his mom? We know with Yusuke there's a sense of "you're not supposed to be dead yet," in Spirit World, which leads to the series starting. Everyone has their time to go."

I want things to get to a point where Shiori finds out about who Kurama is in a way that he can't control, and they both struggle with the realization. It's a horror, so I'm not going to lean into the way she was characterized in the show, tbh. Not in the sense of it being a crackfic, but just...considering realistic reactions to learning something so abstract about your own child.

Author Highlight Thursday: Seruspica

Seru on AO3, Tumblr, and Twitter

It’s been a while since we’ve done one of these and I’m excited to highlight someone I’ve been a fan of for a while. Every one of their fics is utterly fascinating. 

From Suzuki family character studies, to very creative alternate universes (psychic clones! alternate history 1950s!), these are stories you’ll still be thinking about months after you read them.

Seru is also co-organizing the Stories from Seasoning City fanfic zine. They will also be contributing a new fanfiction of their own to the zine. All proceeds will be donated to the Organisation for Transformative Works, the group that runs AO3!

We’re so proud of all that Seru has done for the fandom. Please continue to support them!

the supernatural victims’ society

Asagiri Minori & Claw Security Guard. Post Mogami-Arc. Completed. Rated: T. Word Count: 1908

“Memories are meant to fade. She is supposed to forget. She is supposed to be home, she thinks to herself, and not sitting in the centre of Seasoning, watching the world with a stranger by her side, making ghostly shapes out in the crowds.”

A Revolution in Technicolor

Kageyama ‘Mob’ Shigeo & Reigen Arataka, Kageyama Ritsu & Tsuchiya, Koyama Megumu & Sakurai Yuusuke. 1950s AU, Alternate History. Ongoing. Rated: M. Word Count: 116889

Trigger Warnings: Graphic Depictions of Violence, Minor Character Death, Referenced Terrorism, Swearing

“AU. In an alternate 1950, a shocking leak leads to national scandal. Knowledge of espers—those with powers beyond explanation—has become public. The question of ‘integration or persecution’ hangs heavy over a government in troubled waters.

In the madness, stories entwine: of brothers separated and lost, of a gang boy in denial of his true, terrifying identity, of a child reduced to a bargaining chip in a decades-old game, of a former soldier with memories soaked in light, rain and blood… and of one unfortunate journalist caught in the crossfire.”

One of the longest stories in the fandom!

so foul and fair

Suzuki Shou & Suzuki Touichirou. Psychic Clones, Character Study, Second Person POV, Literary Allusions, Introspective. Comlpleted. Rated: M. Word Count: 13153

Trigger Warnings: Graphic Depictions of Violence, Stillbirth, Background Character Death, Suicidal Ideation, Biblical References, Medical Experimentation

“(You are not scared. You have nothing to fear. You will be feared, instead, when you stand on top of the world. You are not scared of anything: least of all, a child, no matter how much he resembles you.)

AU: in which Suzuki Shou was not created in the way humans typically are, in which a burst of psychic energy becomes the impossible, and in which Suzuki Touichirou is left to make sense of the aftermath, and what came before.”

Shou as Touichirou’s actual clone is one of the greatest theories I’ve ever heard.

house ghost

Kageyama ‘Mob’ Shigeo & Reigen Arataka. Harry Potter AU. Completed. Rated: T. Word Count: 4490

“Harry Potter AU; in which Kageyama Shigeo survived an attack by a powerful wizard three years ago, in which a Muggle died saving him, and in which Mogami Keiji ended himself trying to kill an inconspicuous eleven-year-old—whose name nobody really remembers.

(…or in which, in his third year at Hogwarts, Kageyama Shigeo encounters a ghost.)”

sheltering

Reigen Arataka/Serizawa Katsuya. Fluff, Romance. Completed. Rated: M. Word Count: 741. 

Trigger Warnings: Sensuality, Metaphorical Smut

“If the walls break down, then yes, they will die. If they fall to the water and drown, then wash up in the flood, lungs ballasted by crystallised salt and the heaviness of confessions and loving words—then no, he doesn’t mind, feeling tender lips and stubble-rough skin and the thousand meanings that come with each touch.”

the logic of new beginnings

Suzuki Shou & Suzuki Shou’s Mother. Post-Canon, Manga Spoilers. Completed. Rated: G. Word Count: 1423

““What do you think? It’s not too short, is it?”

Shou gets a haircut.”

six months of hell and thirteen years later

Kageyama “Mob” Shigeo & Suzuki Shou. Age Swap. Completed. Rated: T. Word Count: 17002

Trigger Warnings: Kidnapping, Unethical Experimentation, Trauma

“AU. Thirteen years ago, Suzuki Shou was kidnapped and experimented on under strange circumstances. Now 26, he makes contact with a fellow survivor... but those six months of experimentation have deadly consequences, and his world is about to be turned upside down.

(Alternatively: ageswap with a twist.)”

[arabaka]

*₊˚💬୧ when you first tell serizawa you want kids, you see his entire face light up. he's known for a while just how eager he is to spend the rest of his life with you, but to have your beautiful children along for the ride is a vision that has him over the moon with joy.

so you start trying and right away and... serizawa just doesn't know what's taken over him. now he can't stop thinking of shooting load after load inside of you, thrusting long after he's finished to be sure it sticks. he becomes much more forward with you, needing to take you from behind with his massive cock bottomed out inside you with his hand firmly rooted on your stomach. he doesn't tell you but he uses that prominent bulge on your tummy as practice; it's a good idea of what you'll start to look like, what you'll start to feel like after that first positive pregnancy test.

sex with serizawa was usually reserved for the bedroom but now that you've planted the idea of itty bitty kids running around, he can't help but want to take you everywhere. on the dining room table, with his body lumbering on top of yours while his hips jerk sporadically and sternly into you. over the kitchen counter as you prep dinner, his engorged balls going slap, slap, slap on your quivering clit while you swallow him whole. he even fucks you in the shower, even when he's previously expressed concern about slipping and falling, his big hands leaving red marks on your hips by the time he's done with you. he is insane with lust and with passion; he loves filling you up, scooping up the dribbles of cum that come seeping out of your sloppy wet pussy because he doesn't want a single drop to go to waste.

he has a carnal need to see you swell up with his kin and you best believe he won't stop until the job is done.

DO NOT steal my serizawa banner k thanks!

[arabaka]

Serizawa fingering you for the first time and his hands are so big and meaty that you're all squirmy and whimpering and he's so nervous he's hurt you or that it's physically uncomfortable but you completely take him back when you beg him to add another finger.

ʚ｡ﾟ☁︎｡ɞ｡ when you sent this last night you have no idea the demons that went to war inside this broken vessel of mine. i was tired, i was sick, yet i was FED. I WANTED TO ANSWER THIS SO BAD BUT I. FELL ASLEEP but i'm back and i just -

You have to build up to his length and the fat of his cock. He'll split you in two otherwise. You figured as much the first time you felt it, the mountainous bulge in his slacks pushing against your heat during a heavy petting session one day. Confirmed it for yourself when you couldn't get past half his length when sucking him off for the first time, having to use both your hands as buffers to keep yourself from choking and gagging all over his cock - you'd end up doing that anyways, towards the end when Serizawa started dropping the most beautiful groans and sighs of bliss. He'd cum so much, dick still twitching with it's full girth inside you long after he stopped filling your taste buds with his load.

But the time had finally come and neither one of you could hold off touching the other, over-the-clothes gripping and pawing was no longer enough. You needed him inside you and he needed to be inside you.

"Y-You're so tight," Serizawa hisses at the push back he's getting from your clenching hole, "I-Is this okay?"

You know he's nervous, can see the first bead of sweat along his hairline so you nod, quickly and assuredly, "Katsuya, please - need you." Your chest rumbles with a shaky breath upon feeling the poke and prod of his digit, realizing that the big hands that envelope your own with such warmth feel a lot larger running along your folds. A short and sweet moan pushes up your throat when you finally feel him cross that boundary, your gummy walls immediately tightening around him like a vice. You feel him linger just then and that's when you reach out, hand coming to cup his cheek as you whisper, so laced with lust and need, "Keep going, Katsuya."

He doesn't know how he can. He's scared of going too hard, too fast and hurting you but he listens. He listens and crooks a finger deeper inside you, inching slowly with a buzz in his ear telling him he could get addicted to this. The tightness, the warmth. You tremble around him and he feels it even from within, tingling when the spongy ridges of your cunt flex and twitch over his finger. He gasps in surprise when he realizes that he's already down to the knuckle inside you. "S-Sorry, I didn't - are you okay?"

You nod and not wasting any time, plead in a breath, "Y-Yes, need more, Katsuya. P-Please don't stop."

[arabaka]

Look i know realistically it would rip me in half but play with me in the space for a sec and imagine double penetration with Reigen and Serizawa. Serizawa chooses to be under you because he wants to see your fucked out expression as you sink down on his cock. As you bend down to give him sweet kisses and love bites on his neck, Reigen takes advantage of the position to take you from behind. Serizawa's stable enough for the three of you and helps keep you in place while he and Reigen stuff themselves in your pussy. Reigen kind of leans just a tad bit more on the possessive side, so he physically turns your head back from looking at Serizawa to face him instead for a bit. Seri is a little bummed but takes the opportunity to litter your neck with kisses and bites. Basically it's just the two of them lightly competing for your attention as they completely stuff you.

˚₊‧꒰ა ♡ ໒꒱ ‧₊˚ CW: ass eating, ass play, suggested double penetration

The first time happens in the spur of the moment. You've taken them every which way in every corner of the house and it's just another day filled with sex, sweat, and musk when you croon for Reigen as he eats you out, tongue poking and flicking out your tight little asshole while Serizawa pistons his cock all the way inside your pussy.

"'Taka, need you inside." He thinks you mean his fingers until you cry, note kicked up several notches because of the mean pace Serizawa's started to keep your attention, "Y-Your cock, need your cock!"

"Oh yeah?" You don't have to see him to know he has a brow quirked in curiosity, lips forming a half smile just before he gathers and spits a large glob of saliva onto his flushed pink member. "Can you take it?" His voice low, tip of his member teasing your taut rim, he waits for your answer which comes in no time at all.

"Yes, yes! I'll be good, be good for both of you! P-Please just n-need you!"

Serizawa grabs your face, a little rougher than he intended but the point's been made.

"B-Both of you!"

You don't have to say any more.

N/SFW TEXT AHEAD. thinking about SERIZAWA riding my face and fucking his cock to the back of my mouth, forcing my throat to expand with the fat, seeping tip while he mindlessly murmurs apologies because he's too far gone for any sort of cognitive thought. his knuckles are ghost white as he grips the headboard, his skin aglow with beads of sweat running rivers down his terse arm muscles. his voice starts to corrupt further, serizawa rendered to just a tangle of animalistic grunts and groans by the time he's done humping himself to a stupid thick orgasm. <333

(Idk how far you lean in the monsterfucker scale so obv no pressure to answer or write anything about this)

omg some werewolf Serizawa x reader where he's usually so gentle with you but one day you surprise him during a full moon and get a taste of how animalistc he can be. He's so apologetic the next day meanwhile you're still seeing stars and asking him if he has any plans during the next full moon.

ʚ｡ﾟ☁︎｡ɞ｡ cannot stop thinking about this WILL NOT STOP THINKING ABOUT THIS !!!!!! i am all for monsterfucking, monsterfuckery? but writing for non-human characters is so foreign to me, that i wouldn't even know where to begin as far as learning the terminology and what's hot and attractive K;JF;LKDFJGLS;JFG thus exposing me as old and dumb...

but.

i do have thoughts here

just imagine the physique... his muscles bulking up, nails coming out sharp and black, and the plethora of body hair... he'd be so much stronger during the full moon, he could have you in a full nelson standing up. 100000x more drooly, he salivates all over you and doesn't apologize for it. he crams so much of himself inside you, even when he's knotting he's still fitting more and more. biting your flesh, not for the blood but for the sake of remembering how you taste completely and totally.

and he does feel bad the next day, though he also can't deny he's relieved. relieved he no longer has to hide that side of himself from you. relieved he can finally mark you.
