HAPPY BIRTHDAY TO MY AMAZING BOYFIE ♡

[mytheoristavenue]

Shy Makeouts with Your Fav!

Summary: You initiate a makeout as a confession and he's just putty in your hands!

Warnings: Just fluffy stuff, makeouts, sub!character, dom!reader, gn!reader

"H-Hold on..." He said, staring up at you shyly. He'd always had the softest spot for you and no matter how confident he could be, no matter how resilient- he never could tell you no. That's what had him sitting on his own bedroom floor with you in his lap, kissing down his jaw without any shame for knowing neither had confessed yet.

"Sh-Shouldn't we talk about this first...?" He asked weakly, swallowing thickly as his head rolled to the side to give you more room. This felt so taboo, and yet he had no intent to stop it. "Hey..." He shuddered while your lips brushed his throat, but his palms stayed planted on the floor.

He could never pinpoint what it was about you that made him so shy. Maybe it was you dazzling smile or the mischievous glint your eyes would have when you had an idea that would get him in trouble. Kinda like right now. You were smirking at him for above, peppering his face with kisses, giggling at his blushed cheeks and furrowed brows.

"I'm seriou- ahh..." He sighed, melting when your lips brushed the shell of his ear. Your playful giggle rang in his ears as he tried to muster the willpower to stop you, to make you talk things out with him. "W-Wait, please-" He begged, trembling under your touch, but his arms betrayed him, pulling you closer instead of pushing you away. "Just talk to me, you know I hate it when you get all cryptic..."

"What would you like me to say, big guy?" You finally mused, breath hot on his ear.

"That you like me...?" He confessed with red cheeks. "T-That you keep kissing on me because you want be my..." He didn't have the heart to finish his thought, the embarrassment becoming too much to bare.

"Oh, but I do like you..." You smirk deviously. "And I do want to be whatever it is you want me to be." You didn't miss how his infectious, dopey grin cracked across his face at your confirmation. "There's that cute smile..." You giggled, settling back into his lap as he melted against your touch like butter in a pan. "Now, where where we?"

Class 1B boy Random headcanons ──☆*:・ﾟ

MHA

Summary: Random thinks they do or say as your boyfriend*.•

Characters: Awase, Kaibara, Kamakiri, Kuroiro, Shishida, Shoda, Tsuburaba, Tetsutetsu, Fukidashi, Honenuki, Bondo, Monoma, Rin!

AWASE~

He pranks you all the time, just silly pranks like putting salt in your cereal. Nothing to serious but if he ruins something of your such as cereal he will make you more!

He welds you metal flowers with his quirk and says that cringy ass pick up line “my love for you will stop when this flower dies…btw it doesn’t die :)”

He tried making you food, sometimes it’s good sometimes it not- but you pretend to like it no matter what because it makes him happy and if you refuse it he will look dead in your eyes and say “eat it. Please.”

KAIBARA~

He likes gardening, he used his hands as drills in the dirt which makes it really easy to plant them. He asked you to pick out flowers and seeds to plant! He gives you the flowers he plants!

He loves playing with your hair, he loves curling it around his finger when he is bored

Whenever he gets hurt he whines until you kiss it better. You tend to his wounds then wait for you to kiss if

On the same topic he is kind of clumsy he trips over his own feet sometimes- but don’t worry he will be ok as long as you give him a kiss

KAMAKIRI~

He’s scared to kiss you sometimes because of the sharp appendages sticking out of his cheeks, he worries he may cut you. So you normally kiss him instead of him kissing you

He likes it when you compliment his hair, it makes him feel like a bad ass when you do!

He loves bugs so get him anything but relatable and he will be so touched! You also say he reminds you of a mantis, which he doesn’t mind. He’s sometimes insecure abt his looks so it helps!

KUROIRO~

He is like tokoyami, very poetic so he writes you poems sometimes. If you ask him to read them to you he will stammer over the words and blush about it, he is shy when it comes to you~

He scares you in the dark sometimes, like if the power goes out you literally can’t see him so he could jump scare you; “hey y/n” “HOLY SHIT!” “Oh I’m so sorry!”

He giggles like a dumbass, you could pop the most cringe at joke and he laughs like “hehehehehehehehehe” as if it’s actually funny

He acts cool to other people but once you come into the conversation he turns smitten

SHISHIDA~

He lets you brush his fur, he is sometimes to lazy to do it himself so he lets you do it instead

He sometimes thinks he scares you, he knows he looks a little scary because he is a ‘beast’ but he never wants to scare you so he has to make sure you aren’t. “I’m so sorry did I scare you!” “What no? You could never scare me your like a big teddy bear” “oh!”

You call him big boy to tease him, he blushes about it but does like it~ any time you call him that he covers his face with his hands!

SHODA~

He’s such a cutie patootie, he loves being held by you. When cuddling he will inch closer to you until you wrap your arms around him, he would ask but he’s too scared too

He is insecure since he is a little bigger BUT you make sure he does feel loved anyways by complimenting him or saying it doesn’t matter; “don’t you think I’m too big…?” “what? No! Your adorable!!!” He blushes :>

He cares for your wounds everytime, if you have a cut or something he will always disinfect it and bandage it, he also kisses it if he’s feeling brave!

TSUBURABA~

His idea of flirting is blowing you heart shaped bubbles your way with his quirk, if you pop them he sulks in the corner LOL

He literally thinks your a goddess, bro worships you and the ground you walk on, he would tie your shoes for you, or carry your bags whatever you want him to do!

His friends troll on him for liking you so much, he will NOT stop yapping about you.

Play with his hair. He will die if you don’t; “please I’m literally going to cry if you don’t” “Omg fine I’ll play with your hair.”

TETSUTETSU~

He also worships you but 10x harder, he would kiss your feet if you let him- which also means he is very protective of you. He would bark at anybody who tried anything funny with you

He tries flexing his quirk on you by doing dangerous things, most of the time he gets hurt and when you ask “why would you do that?” He says “I just wanted to impress you”

He worries you secretly like kirishima, since they are very similar. You heard him talking to kirishima saying if he ever when after you he would break him. After that you calmed him down and assured you wouldn’t leave him.

FUKIDASHI~

He makes cute little emoticons at you like (*^‿^*) to distract you from the fact that he is a walking thought bubble-

He reads your favorite manga just to impress you by bringing up scenes in stuff, he’s tryna make you think he is cool!

He’s canonically really short so he’s timid with you sometimes because you are much taller but if he uses his quirk right he can at most be 5,3 which ain’t the best either, you convince him that you don’t mind and honestly find it cute

He’s very shy when being romantic if he tries kissing you he mostly strikes out and flashes a sweat drop emoticon before turning away~

HONENUKI~

Out of everyone in that class he is the shyest with his partner, he is also very low in self esteem cuz of it.

He’s very insecure of his looks, he finds his teeth gross and scary, but you hold him and kiss his cheek letting him cry if he wants until he feels better

He’s great at massages, after training he always massages your neck and back! One time he accidentally hurt you and he cried a little over it-

He’s very funny, he’s your little comedian! He tells you silly knock knock jokes just to heard your sweet laugh~

BONDO~

He’s a very awkward boy, he is honestly shocked that he’s dating anyone let alone you. One he’s very socially awkward and looks different. But you asked him out anyway

He stutters sometimes when talking to you about dates or cuddling; “s-s..sure we can cuddle I g-guess.”

He doesn’t talk much, he definitely talks more than koda but he does shy away because he has voice cracks sometimes and it makes him feel stupid, you find it cute tho

MONOMA~

This little shit, he thinks it’s funny copying your quirk just to show you ‘how easy it is’ but most of the time it back fires and he gets hurt

He turns into such a big baby when he’s hurt, he whines like he’s paralyzed and begs you to care for him. “I need to be held it’s the only way I’ll be comfortable! In your arms!” “It’s not that serious. But fine.”

He’s really good at cooking, he makes full course meals and mostly eats it all himself. He saves a little bit for you tho

RIN~

He’s not shy, or awkward with you he’s just kind of…aloof- he sometimes just stared at you with a straight face like 😐 and when you ask what’s wrong he just goes “I’m just looking at your beauty?”

He loves laying in the sun, and watching the clouds n stuff with you, although he does get sun burned sometimes but he doesn’t listen when you tell him to put on sunscreen so he deserves it

He cares for you so hard, he lays blankets on you, he feeds you, he make sure you drink water! He is such a caregiver because he can’t handle if something happeneds to you.

Omg I love them. ANYWAYS ima post another class 1A Post then ima post a haikyuu headcanon I’ve benn workin on

Not proof readddddd

[koibitokeiko]

Hit with a Villain’s Sex Quirk & They NEED You NOW!

UA Part 1 / UA Part 2 / Pro Heroes / Villains

(All readers are aged up, UA students are now Pro Heroes)

They’re desperate, aching, and the only thing that can ease their suffering… is YOU

Featuring Aged Up: Katsuki Bakugo, Tamaki Amajiki, Hitoshi Shinso, Eijiro Kirishima, Mezo Shoji, Fumikage Tokoyami, Rikido Sato, Tetsutetsu Tetsutetsu

Katsuki Bakugo

The second the quirk hits, he stiffens, his breathing ragged.

Heat floods his body, his skin burning, muscles tense as his fingers twitch.

At first, he tries to fight it. He grits his teeth, growling, his body shaking with need.

“The fck kinda quirk is this?!”*

When he sees you, though? His restraint shatters.

Storms toward you, eyes dark, pupils blown wide.

“Y/N… I need you. NOW.”

Doesn’t even give you a chance to tease him—his hands are on you immediately.

So desperate, so rough, so possessive.

“I don’t care what’s going on. I’m not waiting. I need you—NOW.”

Tamaki Amajiki

Poor baby is MORTIFIED.

Instantly flushes bright red, his body trembling as he fights the intense heat flooding his veins.

His entire body feels like it’s on fire, his mind foggy, his skin overly sensitive.

Covers his face with his hands, breathing heavily.

“N-No, this… I-I c-can’t…”

The moment you touch him, even just placing a gentle hand on his arm?

He shudders, whimpering, his breath hitching as his body reacts.

Tries to hold back, tries to be respectful, but he’s losing control fast.

“P-Please… Y/N… I—I need you… I can’t t-take it…”

Completely desperate, clinging to you, burying his face against your neck.

Hitoshi Shinso

Staggers when the quirk hits, immediately groaning as heat pools low in his stomach.

Tries to act cool about it, but his body betrays him.

His hands grip whatever is closest, his breathing getting heavier as his pupils dilate.

“Sht… this is bad…”*

When he sees you, his control completely shatters.

“Y/N… I need you. Right now.”

He doesn’t care where you are—he’s dragging you somewhere private immediately.

Voice is lower, raspier, completely wrecked with need.

“Please, don’t make me beg.”

Eijiro Kirishima

Gasps when the quirk hits, stumbling slightly as his body reacts.

His hands clench into fists, his breathing ragged.

At first, he tries to shake it off, grinning nervously.

“Ha… ha… wow, uh… I think something’s wrong…”

Then it gets worse. The ache deepens, and suddenly, nothing else matters except YOU.

Finds you as fast as he can, panting, his hands shaking as he grips your shoulders.

“Babe… I don’t think I can—”

His usual restraint is GONE. He’s all needy, desperate, primal desire.

“Please, I need you. NOW.”

Mezo Shoji

The second the quirk hits, he stiffens, all six arms trembling as he gasps sharply.

His entire body feels like it’s burning from the inside out.

His self-control is legendary, but even HE is struggling.

His hands grip the nearest surface, fingers digging in as he fights to stay upright.

“I… I don’t know how much longer I can…”

When he sees you, everything clicks.

His instincts scream for you, his restraint slipping as his entire body begs for relief.

Slowly approaches, his voice strained and breathless.

“Y/N… I need you.”

Fumikage Tokoyami

Dark Shadow immediately panics.

“Uh, boss? You okay? You’re looking kinda… HOT.”

His whole body is tense, shuddering with need as he struggles to stay composed.

His usual calm demeanor? Completely shattered.

Grips onto the nearest surface, his breathing heavy and controlled.

“This… this is unbearable…”

When he sees you, his control is gone.

Dark Shadow snickers. “Ohhh, I see what’s happening. You need your mate, huh?”

You barely get a word in before he’s pulling you close, his voice low and urgent.

“Help me, Y/N. I need you.”

Rikido Sato

Groans immediately, his entire body stiffening as the quirk washes over him.

His hands clench into fists, his breath coming out in short, shaky gasps.

He’s used to handling intense physical strain, but THIS? This is a whole different challenge.

His body feels heavy, hot, aching for you.

When he finally finds you, he grips your waist tightly, his forehead resting against yours.

“I— I don’t know how much longer I can hold on…”

Completely desperate, pressing himself against you.

“I need you, babe. Right now.”

Tetsutetsu Tetsutetsu

Grunts when the quirk hits, shaking his head as heat floods his body.

His entire body aches with need, and he groans loudly.

“O-Okay… this is… wow, this is bad.”

Tries to act tough, but he’s struggling.

His steel skin is practically radiating heat, his fingers twitching at his sides.

The moment he sees you? He sprints to you, grabbing your wrist with a desperate grip.

“Babe— I NEED you. Now. Please.”

His usual competitive nature is gone—he’s completely at your mercy.

How they react to accidental hand touches...

UA Part 1 / UA Part 2 / Pro Heroes / Villains

When your hand accidentally brushes theirs how will they react? More adorable moments with my absolute favourite boys!

Featuring: Katsuki Bakugo, Tamaki Amajiki, Hitoshi Shinso, Eijiro Kirishima, Mezo Shoji, Fumikage Tokoyami, Rikido Sato, Tetsutetsu Tetsutetsu

Katsuki Bakugo

Immediate scowl.

"The hell was that?!" Snatches his hand back like it personally offended him.

Crosses his arms, looking anywhere but at you.

Ears? Bright red.

His brain is absolutely screaming. "WHAT THE HELL?! WHY WAS THAT NICE?!"

If you apologize, he just grumbles, "It’s whatever."

If you tease him, he explodes (but doesn’t deny he liked it).

Later, he’s thinking about it way too much.

If you do it again, he might let it linger a second longer before pulling away.

Tamaki Amajiki

Instant panic.

Face turns beet red in under two seconds.

Immediately retracts his hand, but so gently like he’s afraid of hurting you.

"S-Sorry… I didn’t… I mean… um…"

Cannot form a sentence.

Looks away so hard, he might sprain his neck.

Mumbles something about needing to go but doesn’t actually move.

If you brush his hand again later, he might actually combust.

But deep down? He really, really liked it.

Hitoshi Shinso

Smirks immediately.

"Oh? Look at you, making moves."

Acts like he’s not flustered but is absolutely internally screaming.

Doesn’t move his hand away right away, just to see what you do.

If you get flustered, his smirk gets bigger. "Aw, did I make you nervous?"

If you don’t react much, he plays it off like it was nothing, but he keeps thinking about it.

Later, his brain replays the moment while he stares at the ceiling like, "I’m so screwed."

Lowkey hopes it happens again.

Eijiro Kirishima

Immediate sunshine smile.

"Oh, hey! That was cute."

Doesn’t pull away at all.

If you look flustered, he gently squeezes your fingers before letting go.

"You’ve got soft hands!" Says it so casually, like it’s the most normal thing ever.

If you pull away quickly, he looks a little confused but doesn’t push.

But if you don’t pull away? He just keeps holding your hand because why not?

Completely chill but definitely thinking about it later with a lovestruck grin.

Mezo Shoji

Freezes.

Glances down at your hands, then up at you.

Eyes widen slightly, but he doesn’t pull away immediately.

"…Sorry. I didn’t mean to." Says it softly but doesn’t sound uncomfortable.

If you don’t mind, he’ll just keep his hand where it is.

So, so gentle. His touch is light, like he’s afraid of startling you.

Absolutely overthinking it later.

If you do it again, he subtly shifts his hand so it lingers a little longer.

Fumikage Tokoyami

Completely stills.

Barely reacts externally, but inside? "Oh. Oh no. Oh dear."

"Pardon me." Says it so formally, like he just bumped into a royal.

Pulls his hand away gracefully, but his feathers are slightly puffed up.

Acts composed but is 100% replaying the moment in his mind.

If you do it again, he pauses for a second longer before withdrawing.

Might secretly enjoy the warmth of your touch way more than he expected.

Rikido Sato

Blushes immediately.

Kind of stiffens for a second but doesn’t pull away.

"Oh! Uh… my bad." Laughs a little awkwardly.

Tries to act like it’s not a big deal, but his cheeks are definitely pink.

His brain: "That was nice. Do it again."

If you make a joke about it, he just laughs it off but gets even more flustered.

If you do it again later, he just smiles softly and lets it happen.

Tetsutetsu Tetsutetsu

Doesn’t realize at first.

Then he notices and immediately tenses up.

"OH CRAP, SORRY!" Yells unnecessarily loud.

Jumps back slightly like he just got electrocuted.

If you laugh, he gets embarrassed but grins anyway.

"Didn’t mean to get all up in your space!" Scratches the back of his neck sheepishly.

Secretly overthinking it later like, "Did they mind? Did they like it? Am I dumb?"

If you do it again, he might get flustered but grins and lets it happen.

Tetsu... 😭 YES he is SO dumb and i love him so much 🫶🫶

[mystt-ifying]

Men who would have such big cocks that would make you ride them and you can't even get it halfway in before your fucked outta your mind, small drops of your saliva drooling out your mouth as you beg him for help. His hands on your hips guiding you slowly and slowly as you fully take him in, big belly bulge immediately popping out of your stomach.

Men who have such big dicks that you make them hold your hands when you're riding them. Bouncing on his dick coated in your arousal, going on your own pace until you feel your legs go numb and the feeling of him filled in you was making you more cock drunk. You slowly got rid of his hands on your hips and instead hold his hands as support while you slowly bounce up and down on his cock until a white ring forms around his dick as he fills you up with his seed.

Bathroom Confidential ♡

Pairing: Tetsutetsu Tetsutetsu x amab!Reader

Rating: Explicit

Tags: Semi-public setting, sub!Tetsutetsu, dom!Reader, frotting, heated make-out session.

The tiled echo of the empty bathroom during lunch break made every sound feel like it bounced a little too loud off the walls. But that didn’t stop you. Not when Tetsutetsu looked at you like that—flushed, needy, his breath already catching just from being pinned between your body and the cool wall of the stall.

He had pulled you in by the collar with some flimsy excuse, but now he was the one squirming, lips red and kiss-bitten, chest rising fast under the tight cling of his uniform shirt.

You grabbed his hips and rolled against him, slow but with pressure, grinding your hardness against his in a hot, desperate rhythm that made him gasp into your mouth. His hands scrabbled at your back, trying to pull you closer, trying not to moan too loudly.

“Quiet,” you whispered, lips brushing the corner of his mouth. “You’re gonna get us caught.”

“I-I’m trying,” he whispered back, but his voice cracked when you rolled your hips again, harder this time. His head tipped back against the wall, eyes fluttering, teeth sinking into his lip as he trembled beneath you.

The friction was intense—uniforms rumpled and bunched up around your waists, your cocks grinding together through the fabric, heat and pressure building fast. Tetsutetsu whimpered, breath hitching, and that was your cue.

You slapped a palm over his mouth, pinning him there, your hand big enough to muffle the next sharp sound he let out.

“Better,” you growled low against his throat, kissing and biting down along the skin as he writhed in your grip. “You’re such a mess already, and I’ve barely started.”

His eyes were wide, glassy, cheeks flushed a brilliant pink as he squirmed in place, letting you take full control of the pace—slow, steady friction that made his knees weak, every grind of your hips sending sparks shooting through both of you.

He was panting now, muffled under your palm, his fingers digging into your shirt, the tension in his body building fast.

You kept your eyes locked on his—watching him unravel, watching every twitch and moan that slipped past his bitten lips. You leaned close, mouth brushing his ear.

“You gonna make a mess for me just like this?” you whispered. “Just from rubbing up on each other like a couple of desperate idiots in a school bathroom?”

He nodded, whining under your hand—so needy, so sensitive, grinding helplessly back against you like he couldn’t stop even if he wanted to.

And when he came—trembling, muffled, eyes wide and teary—you followed with a sharp groan, burying your face in the crook of his neck as the two of you came undone together, pressed tight in a tiny bathroom stall while the rest of the school sat clueless in the cafeteria.

When it was over, you slowly peeled your hand from his mouth, and he let out a shaky laugh, still breathless, still clinging to you.

“We’re so gonna get detention one day,” he mumbled.

“Worth it,” you smirked, pressing a soft kiss to his temple.

Footnotes ♡

Pairing: Tetsutetsu Tetsutetsu x afab!Reader

Rating: Explicit

Tags: footjob, subby!Tetsutetsu, under desk, flirty reader, gn!reader, non-established relationship.

The quiet hum of the heater and the rustle of notebook pages were the only sounds in the room, save for Tetsutetsu’s soft, frustrated grumbling. He was hunched over his chemistry notes, brow furrowed, pen held between his teeth as he stared at the same equation for the third time.

You sat across from him at the low kotatsu table, legs stretched out under the warm blanket, your own notebook forgotten as you watched him squint at the page like it had personally insulted him.

“You okay there, genius?” you asked, barely holding back a smirk.

“M’fine,” he mumbled around the pen, then yanked it out with a sigh. “I just—why does stoichiometry hate me?”

You giggled, eyes dropping slightly—past the table, under the blanket, where his leg was stretched out and unaware of the trouble it was about to find itself in.

You shifted slightly, slow and casual, until your foot brushed gently against the inside of his ankle. Just a light touch—barely anything—but enough to make him jolt like he’d been shocked.

“W-What’re you—?” he looked up sharply, his face already turning pink.

You raised a brow, playing innocent. “What? Did I startle you?”

He opened his mouth, then closed it again, clearly not trusting himself to speak. You smiled, letting your toes trail just a little higher, brushing along the muscle of his calf under the fabric of his sweatpants. He bit down on the pen again, hard.

“You seem tense,” you teased, voice low, your foot now slowly sliding higher up his leg. “You should relax a little.”

His breathing quickened. He was frozen, eyes flicking between you and his hopelessly abandoned notebook. You watched him closely, your movements unhurried as your foot found its way to his inner thigh, feeling the heat radiating from him even through the layers.

His cheeks were crimson now. “We—we’re supposed to be studying…”

“You can still answer chemistry questions while squirming, can’t you?” you whispered, letting your foot brush against something harder now—very hard, judging by the way he stifled a breathy moan and gripped the edge of the table like it might keep him grounded.

Tetsutetsu’s knuckles were white, his eyes wide, lips parted in a quiet gasp as you pressed your foot more firmly between his legs, teasing pressure and friction while he tried—and failed—to keep his composure.

His head dropped forward, forehead nearly hitting his notebook, a soft whimper slipping from his throat. “This is s-so not fair,” he muttered, voice shaking.

“Could stop if you want,” you offered, dragging your foot away ever so slightly.

“No!” he blurted, eyes snapping up. “I mean—n-no, it’s fine, just…”

His voice trailed off into a helpless whine as you began moving again—slow, rhythmic, maddening. He squirmed, his hips twitching slightly as he tried to stay quiet, but you could see it all over him: the way his eyes glazed, his breathing hitched, his body begged for more.

Under the table, it was hot. Tension rising. Breath catching. And across the table, Tetsutetsu looked wrecked—flushed, panting, trying to keep from making too much noise as you pushed him closer and closer to the edge with nothing but your foot and a wicked smile.

You leaned in just a little, letting your voice drop to a sultry whisper. “Still think stoichiometry’s the hardest thing you’ll deal with tonight?”

He moaned—quiet, desperate—and dropped his head into his arms with a strangled, “Oh my god…”

Sweet After Heat ♡

Pairing: Tetsutetsu Tetsutetsu x afab!Reader

Rating: Teen and Up Audiences (13+)

Tags: aftercare, fluff, mentions of suggestive content, domestic.

The room was warm, still heavy with the scent of skin and sweat and something more intimate. Your limbs felt like jelly, boneless and trembling in the most satisfying way, while the sheets beneath you were rumpled beyond recognition. Every inch of you hummed, glowing with the aftershocks of being thoroughly, lovingly wrecked.

Tetsutetsu hovered above you for a moment, eyes hazy but soft, silver hair damp and wild. He reached up and gently brushed your hair from your face, his fingers trailing across your cheek like you were something delicate, breakable. His thumb paused at your lips, swiping across them like he still couldn’t believe what just happened.

"You okay, babe?" he whispered, voice hoarse from moaning your name like a prayer not that long ago.

You gave a dazed little laugh, nodding as you pulled him down to rest against you. “More than okay.”

He grinned—wide and boyish, a flash of sharp teeth and warmth—and let out a breathless chuckle before collapsing beside you, tugging you close so your head rested on his chest. His heartbeat was still fast, thudding against your cheek like it was trying to catch up to reality.

"That was... wow," he muttered, still half out of it. "You’re dangerous, y’know that?"

You lifted your head slightly to smirk at him. “Says the guy who almost broke the bed.”

He barked a laugh, rubbing the back of his neck sheepishly. “Okay, that wasn’t on purpose.”

You cuddled in closer, fingers tracing lazy patterns along his torso. He was warm—solid muscle and soft skin—and you never wanted to move again. He smelled like clean sweat and your perfume and a little like the vanilla-scented laundry detergent he never admitted to using.

A beat passed before he whispered, “Hey… did I hurt you? At all?”

The concern in his voice was real. Gentle. Like even after everything, all he really wanted was to be sure you felt safe, loved.

You shook your head, smiling against his chest. “You were perfect. Seriously.”

He let out a sigh of relief, kissing the top of your head. “Good. You just… mean a lot to me, y’know? I never wanna push too hard.”

You tilted your chin up to kiss him—slow and lazy, mouths brushing more than meeting. “You’re sweet,” you mumbled, lips still against his. “Too sweet for someone who manhandled me like that five minutes ago.”

“Ohhh, so you liked that,” he teased, grinning again, eyes gleaming now.

You rolled your eyes, laughing. “Shut up and get us some water.”

“Yes, ma’am,” he said with a dramatic salute, slipping out of bed and walking—still gloriously shirtless—toward the kitchen.

You watched him go, heart full, body sore in the best way, and already smiling in anticipation of curling back into him once he returned with two glasses and that crooked, lovesick grin.

Tetsutetsu was already flushed pink all the way to the tips of his ears.

He sat on the edge of the bed, legs spread, muscles tense, and eyes wide as you knelt between them. Your hands slid up his thighs slowly, teasing, but your mouth was anything but gentle. The moment your lips wrapped around him, his entire body jolted.

He gasped, head tipping back, one hand flying to your hair as if it was the only thing grounding him. “S–so good,” he stammered, voice cracking, hips twitching despite himself.

You took him deeper, slowly, deliberately, letting him feel the drag of your mouth, the pressure, the heat. His grip in your hair tightened as a shaky breath escaped him—half moan, half whimper.

“D-Don’t stop,” he pleaded, blinking fast. His cheeks were glowing hot, eyes wet at the corners, overwhelmed by how much it was. You kept going, relentless and smooth, your tongue teasing just right, your throat taking him inch by inch until his moans turned into broken, high-pitched cries.

You felt him try to hold back—trembling, whining—but then he lost it.

Tetsutetsu’s hips bucked forward, and he started to move, unsteady at first but quickly finding a rhythm. He was face-fucking you now, panting, clutching your hair like he needed you more than air, every thrust sending choked moans tumbling from his lips.

“I—ahh—I'm gonna—!” His voice cracked again, desperate and breathless.

Tears welled up at the corners of his eyes as the pleasure overwhelmed him. He looked down at you, mouth parted, face a mess of flushed skin and glossy eyes. “You’re… ngh, so good to me—so f-fucking good…”

You kept your hands on his thighs, letting him have you completely, letting him chase the edge until his voice broke into a loud, needy cry and he stilled, trembling as he hit his peak hard.

He fell back onto his hands after, breathless, face pink, chest rising and falling in uneven gasps.

When you looked up, he was still blushing like mad, eyes watery and dazed, lips parted in awe. “…Holy shit,” he whispered, voice hoarse, “you ruined me.”

TW: Light choking.

Tetsutetsu was already shaking.

You had him on all fours at first, gripping his hips hard enough to leave finger-shaped dents as you drove into him with relentless rhythm, every thrust slamming deep, every sound he made feeding the fire burning through your veins.

But that wasn’t enough.

You grabbed him by the throat—firm, controlling, not choking but owning—and pulled him up, dragging his back against your chest. He gasped, his whole body twitching as he tried to stay upright, legs trembling beneath him.

“You’re gonna take this,” you growled into his ear, voice low and firm, “and you're not gonna stop until I’m done.”

He let out a broken whine, head tilting back against your shoulder, mouth open, eyes fluttering. Every time you thrust up into him, his breath hitched, body jolting with overstimulation. His hands flew out, searching for something to hold on to, but you had him completely controlled—his hips locked in your grip, his throat under your palm, and your body dictating the pace.

The slap of skin was loud, desperate, echoing with the wet, ragged sounds of pleasure he couldn’t stop. His voice cracked between moans, trembling with every sharp grind into that one perfect spot that made him fall apart.

“Y-You’re so deep—” he sobbed, voice catching, “I c-can’t—!”

“You can,” you snapped, not slowing for a second. “You’re doing so damn good, Tetsu. Taking me like you were made for it.”

That praise undid him. He was crying now—loud, choked sounds as his whole body tensed, his legs threatening to give out, but you kept him upright, fucked into him harder, deeper, until he was a babbling, whimpering mess in your arms.

You could feel him clenching tight around you, pulsing, his entire body trembling from the overload. And then he came, hard, untouched—his moans sharp and desperate, whole body shaking as he released, helpless and perfect.

You weren't far behind—dragging him down onto you, locking your arms around his waist, burying yourself to the hilt as you spilled deep inside him, groaning low against his sweat-slicked neck.

Tetsutetsu collapsed forward afterward, completely boneless, still whimpering softly into the mattress as you lay behind him, wrapping him in your arms.

“You were perfect,” you whispered into his hair, kissing his temple.

He didn’t say anything—he didn’t have to. The way he melted into you, trusting and thoroughly wrecked, said everything.

The room was filled with the sound of skin meeting skin—sharp, rhythmic, relentless.

You were bent over the bed, gripping the pillow so hard your knuckles had gone white, your face buried deep into it as the force of Tetsutetsu’s thrusts knocked the air from your lungs over and over again. Every time he slammed into you, you groaned—loud, ragged, on beat with his pace, like your body had no choice but to react.

Behind you, Tetsutetsu was a mess.

His strong hands gripped your hips like they were his anchor, but he couldn’t stop shaking. His thrusts were deep, fast, rough—like he was trying to get impossibly closer, to leave every ounce of himself inside you. He moaned freely, voice cracking and breath hitching with every snap of his hips. Whines slipped out between gasps, and the occasional high-pitched whimper escaped when you clenched around him.

“F—fuck, baby, you’re so tight,” he groaned, voice strained, his breath hot against your shoulder. “I can’t—I’m gonna lose it…”

You only pushed back harder, your body arching for more. That just made him unravel further. One of his hands tangled in your hair, yanking your head back gently but firmly, exposing your neck to his mouth. He bit down, leaving hickeys and marks like he couldn’t stop claiming you, over and over.

“You take me so well,” he panted, his voice thick with praise and desperation. “So perfect. This ass—yours—drives me insane…”

He was grinding deeper now, hitting that spot inside you that made your entire body jolt, your voice breaking into near cries. The pillow muffled your sounds, but not enough to hide how wrecked you were—drooling, dizzy, your thoughts reduced to heat and rhythm and the sound of Tetsutetsu moaning your name like it was the only word he knew.

Your legs trembled under you, and he noticed.

“Hold on,” he growled, both hands gripping your waist now, slamming into you harder. “You’re not tapping out on me yet. I’m not done filling you up.”

You could barely speak, barely think, as your body was pushed past its limit—pleasure and pressure building with every thrust, every deep grind that made your whole body clench around him in helpless reaction.

And he loved it. Loved how wrecked you were. Loved the way your back arched, how your moans came out broken and desperate. Loved seeing you completely undone by him.

“I’m gonna fill you,” he cried out, biting down again, “and you’re gonna take it. You want it, don’t you?”

You nodded into the pillow, gasping out, “Y-Yeah… don’t stop—”

He didn’t. Not until he broke completely, loud and raw, his body jerking against yours as he pressed deep, holding you tight, pouring himself into you with one last, rough thrust that left both of you trembling.

When it was over, he collapsed forward, chest against your back, arms wrapped around your waist, holding you like he never wanted to let go.

“You’re… insane,” he mumbled into your shoulder, still breathless, voice dazed and soft now.

You laughed weakly, barely able to move. “You're the one who just made me forget how to walk.”

Tetsutetsu kissed your spine, his touch suddenly gentle, warm. “Then we’re even.”

You don’t remember how long you’ve been at it—not that it matters. When Tetsutetsu’s got you like this, tangled in his sheets with your thighs spread and his head buried between them, time sort of stops existing.

“Fuck—Tetsu, yes, just like that,” you gasp, hips twitching as his tongue drags up your center again.

He groans into you like your moans are the only thing keeping him alive. One arm’s slung around your thigh to hold you in place, but his free hand’s clenching the sheets, knuckles pale despite the sheen of sweat across his metallic skin.

You glance down and your heart squeezes. His eyes are locked on you, pupils blown wide, practically pleading. Not for you to stop. Not even for you to take over. Just... for more.

“You’re doing so good, baby,” you breathe, threading your fingers through his sweat-damp hair. “God, you make me feel so fucking good—”

That’s all it takes for him to whine—an actual, shaky whimper from the indestructible, steel-skinned powerhouse. His hips rut into the mattress beneath him, completely untouched, as if your praise is all the stimulation he needs.

“You’re perfect like this,” you tell him, rolling your hips into his mouth. “My good boy—fuck, just like that—”

A broken moan spills out of him, and then he’s everywhere. Kissing, licking, sucking with so much focus it nearly knocks the breath out of you. He’s desperate to please, to be told he’s doing it right. He lives for your approval.

“Tetsu—Tetsu, I’m gonna—” You barely get the words out before it crashes over you. He doesn’t stop, not even as your thighs tremble and your fingers curl tight in his hair.

When you finally come down, he pulls back slowly, panting, face flushed and wet with you. He looks almost dazed, drunk on your taste and your words.

“You’re so good to me,” you whisper, cupping his jaw. “My sweet, strong boy.”

His hips twitch again, a low groan spilling from his lips like he’s about to lose it right there.

“C’mere,” you murmur, pulling him up for a kiss. “You want more?”

Tetsutetsu’s voice is rough, needy. “Only if you keep saying that stuff. Makes me wanna give you everything.”
