A/N: happy birthday to us TEEHEE 🤭 also if this looks familiar its bc i recycled lines from something i shared and then never continued writing so just ignore that iykyk....
Thinking about Best Friend!Satoru x Reader..
Best Friend!Satoru who you’ve known since diapers. Whose baby photos are so intertwined with yours that your parents have to squint to remember which toddler was the menace that bit the neighbor’s kid (he insists it was you – it was most certainly not).
Best Friend!Satoru who grows into himself obnoxiously fast. Limbs too long and voice too loud and smile too sharp, looking at you like nothing has changed. Like you’re still the girl two inches taller who used to steal his snacks at recess and boss him around with a gap for two front teeth.
Best Friend!Satoru who grimaces when Suguru asks if you’re dating. Makes a whole show of gagging, dramatically collapsing onto the nearest surface like the idea alone has physically wounded him. “Me? With that hag? If I was attracted to her, I’d cut off my left ball–”
Your brow twitches, and you stomp on his foot. Hard. “Fuck you. Suguru, if I was attracted to him, I’d go bald.”
“Fine, fuck! Both balls then.”
Best Friend!Satoru who just doesn’t see the appeal. When guys go to him asking for advice – what you like, how to impress you – he shrugs them off with a languid flick of the wrist. “Dunno, man. Ask her. She bites.”
(he chooses to ignore the vitriol curdling in his stomach every time some hopeful idiot says he wants to “shoot his shot.”)
Best Friend!Satoru who claims he’s just being helpful. Surely. But he always fucks it up somehow.
“No, don’t take her out there. She’s scared of truffles.”
“Sorry?”
“Yeah. Reminds her too much of her feet, I guess.”
“Oh.”
Best Friend!Satoru who acts horribly offended when you confront him the next day. You’re sitting cross-legged on his bed as he games with Suguru on call, your arms folded across your body and voice shrill. “What the fuck happened yesterday, Satoru?”
“Why’re you asking me? I don’t keep track of your love life.”
“You ruined my date.”
“You lie.”
“You told him I had foot fungus.”
Satoru pauses the game and turns. Glances down at your socks, then back up at you with a scrunch of his nose.
“He looked like the kind of guy who sucked toes, so I had to warn him.”
“I don’t have foot fungus, Satoru.”
“You could. Someday.”
Best Friend!Satoru who tells himself he’s the same old him. You’re the same old you. Except he keeps catching himself staring at your mouth when you talk and your throat when you swallow and your pretty eyes and your pretty smile and your pretty tits (fuck, when did you get those?).
Like, objectively, they’ve always been there. But now they’re just.. there. And he’d be unappreciative not to look and admire, if only a little.
Best Friend!Satoru who finds himself wondering how soft they’d feel, how your nipples would look hard and wet from his tongue. How your neck would look with his marks painting your skin.
Then he blinks, realizes he’s half-hard in his sweats, and immediately starts complaining about being hungry again to distract everyone (mostly himself, and god, he’s hungry for so much more).
Best Friend!Satoru who – when you crash at his place after movie night and fall asleep on his couch with one leg thrown over the backrest and your shorts riding up so high he can see the little dimple where ass meets thigh – has to take the longest, coldest shower of his life.
Best Friend!Satoru who jerks off so hard he sees stars, biting down on his bottom lip so you don’t hear the way he whimpers your name like a pervert.
Fuck.
You.
He cums embarrassingly fast when he remembers you’re in the next room over. Spilling hot into his hand, groaning at the sheer amount. He then emerges half an hour later like nothing happened and tosses a blanket over you while muttering “slutty sleeping positions, jeez” under his breath.
Best Friend!Satoru who keeps telling Suguru “no, dude, she’s not my type”. To which Suguru raises a brow – because he sees the way Satoru smiles when you laugh.
He hums. Watches Satoru stare at you for a full ninety seconds longer – then raises his brow higher.
"Your balls are on the line, Satoru."
"Fuck."
Best Friend!Satoru who knows that you know that he likes your tits. Nothing really ever gets past either of you when it comes to each other. You call him a boob-obsessed pervert. He doesn’t argue, for once – because there’s nothing false about that statement.
Best Friend!Satoru who ends up drunk at your place one night. His head’s in your lap and you’re playing with his hair and his filter just.. evaporates, because he’s in your bed, and god, you’re pretty, and your tits are staring right at him, and fuck, he likes your tits, and he likes you.
“If I motorboated you right now, would you kick me out or moan?”
“Excuse me?”
He repeats the question, and you stare at him before laughing. So hard you snort, which makes him groan and hide his face between your thighs (out of embarrassment, and not for any other reason. no, no alternative motives at all).
“What would you even do if you saw bare boobs, Satoru?”
He gives you an incredulous look. Like it’s obvious.
“Uh.. duh. Squeeze ‘em. Bounce ‘em. Stick my face between ‘em and go brrr.”
He pauses. Looks at you as if waiting for approval. Then raises a hand and makes a little grabby motion mid-air.
“Honk honk.”
You blink, slow.
And maybe because you’re tipsy, maybe because his cheesy grin makes your stomach flutter, maybe because of some dumb concoction of the two – you tug your shirt up. Letting your tits spill free. “Okay.”
And for once in his life, Gojo Satoru is speechless.
No way.
There’s no way you– you, his dumb, stupid, gorgeous, absolutely-nothing-more-than-friends best friend – are in front of him right now. With your tits out. He’s gotta be delusional. Maybe this is one of those dreams he gets where you lean forward and kiss him and he wakes up with a wet spot in his boxers and the afterglow ringing in his ears.
Your shirt’s bunched just beneath your collarbones, tits sitting pretty like it’s nothing. And you’re perfect, just like you always are, and they’re perfect, just like he thought they’d be, and a flush is spreading across his face, and his dick is twitching so hard it hurts.
“Satoru.”
“Mm..?”
“You’re staring.”
“Whoops.”
You raise a brow. “You begged to motorboat me. So do it, loser.”
He answers with a wrecked noise wrangled from the throat – half-laugh, half-groan. Ridiculously long fingers landing on your bare waist as he surges up.
“Fuck,” he whispers. Mouth dry, hands clammy, eyes blown wide as his gaze snaps from your face to your tits to your face to your tits and then all the way down to your sleep shorts before back up. “You’re serious? You’re letting me–?”
“You’ve got about ten seconds before I change my mind, Satoru.”
And oh, that does it.
Best Friend!Satoru who lunges.
Zero hesitation and zero finesse and pure, greedy desperation. His face buries itself between your breasts with a muffled, ridiculous brrrrrrr that vibrates straight through your skin. Nose dragging along the inner curve of one, lips brushing the other, cheeks hollowing as he shakes his head side to side like he’s trying to drown himself in your cleavage. The vibration makes you squeak, before the sound dissolves into breathless laughter.
“You absolute fucking dork–”
He pulls back just far enough for you to see his face – flushed crimson from the tips of his ears to the hollow of his throat, tongue darting out to lick his lips. Lashes fluttering as he stares up at you in open awe.
“They’re perfect,” he whispers, voice cracking, “so fucking soft, holy shit– fuuuck, I might die. Am I dead? Oh, if I am, I’m so, so happy about it.”
Then he dives back in.
His lips are soft and his mouth is hot and he’s relentless – tongue laving open-mouthed kisses over every inch of skin, swirling slow, filthy circles around one nipple until it stiffens into a tight, aching peak. When he closes his lips and sucks – hard – your back arches off the bed. Fingers twisting viciously in his hair.
He groans at the pull, hips jerking forward. Grinding against the sheets.
“Look at these,” he murmurs, hoarse. Hands sliding up to cup your breasts, long fingers splaying wide as his thumbs brush over your split-slick nipples. “Been thinking ‘bout them for years, y’know? Every time you wore those stupid tops and leaned over to steal my fries and hugged me and they pressed against my body– shiiiiit, had to count backwards from a hundred. Didn’t wanna pop a boner in public like a perv.”
And oh, you see it. His hard-on, all warm and thick and pulsing with every heartbeat.
He’s so hard it has to hurt.
“Perv.”
He freezes. A full-body shudder rips through him.
“Don’t,” Satoru whispers. “Don’t– hah– or I’ll cum in my pants right now. I’m not joking.”
You giggle. Fingers running through his hair, cradling his head to your chest.
“Peeeeervert.”
“You’re evil,” he whispers, nuzzling closer. “You’ve always been evil. I hate you so much.”
“You’re literally suffocating yourself between my tits right now.”
“I take it all back. I love you. Never change. Marry me. Have my babies. Name them all after me–”
Best Friend!Satoru who thinks that taking off clothes is suuuuch an inconvenience. He does it because he has to, but really – you’re best friends. You shouldn’t need to wear clothes around each other. If you’re naked in his room all the damn time, then hey, that’s just what best friends are for. And honestly, while he’s at it, what’s a little cock, too? What are best friends for if not fucking?
Best Friend!Satoru who’s on his knees between your thighs before you can even catch your breath, long fingers spreading you wide, eyes glittering in the low light.
“Fuck, look at you,” he breathes. Voice wrecked, thumb sliding through your slick folds just to watch you twitch. “Soaked, huh? Hiii, pretty girl. I know. ‘Toru’s here, baby.”
You barely manage a snarky shut up before he spits – deliberate, filthy – right on your clit. Watches it drip slow and nasty down to your entrance, then drags two long fingers through the mess, mixing it all together before pushing inside without warning.
The stretch makes you gasp – and then he curls his fingers just right, and you swear you see stars.
Best Friend!Satoru who lets out a murmured “attagirl” while he pumps his fingers into your pussy. You’re unsure as to whether he’s speaking to you or your cunt – scissoring you open as his tongue flicks out to swirl ‘round your clit.
“Mmm. Been dreaming ‘bout this pussy, y’know? Used to jerk off in the shower imagining your taste and then– fuuuck, yeah, post-nut clarity would hit so fucking hard. Felt like shit. This feels like heaven.”
Best Friend!Satoru who seals his mouth over your clit and sucks. The way he sucked on your nipples earlier, only harder, and filthier. Tongue flicking fast and then slow and then spelling his own name out against your cunt because of course he does.
“Satoru– fuck! Slow down–”
Best Friend!Satoru who does not slow down. Instead, he pulls off just long enough to grin up at you, lips shiny, chin dripping – “No.”
Then he’s hauling you up by the thighs, lying back against the sheets and dragging you over his face.
“Sit,” he grins. “Sit. Want your thighs around my head when I make you cum.”
Best Friend!Satoru who frowns when you hover just above. Who yanks you down until you’re smothering him, nose buried against your clit, tongue swirling inside you alongside two of his fingers, knuckle-deep. He’s moaning like he’s the one getting eaten, hips grinding uselessly against the air, a pretty bead of pre-cum dribbling down his cock.
And every time you try to lift up to give him air, he pulls you back down harder.
“No, no, use me, baby. Use me. Ride my face. Want you to drown me.”
Your thighs shake.
You’re close, so close, grinding down shamelessly now, chasing it – and he knows. He always knows. Just like he knows the sky is blue and the grass is green and he loves his best friend’s pussy so, so much.
Best Friend!Satoru who sucks your clit into his mouth one last time. Crooks his fingers just right. And then you’re crashing into your high, cumming with his name all sweet on your tongue, gushing while he drinks you down like he needs your arousal to stay alive.
Best Friend!Satoru who doesn’t stop until you’re trembling, oversensitive, trying to squirm away – and only then does he let you collapse beside him. He’s panting, face flushed a cherry pink, lips swollen and glossy with you. Sprawled on his back with an arm flung over his eyes, both of your chests heaving in sync.
You nudge his ribs. “You good, weirdo?”
He doesn’t move his arm. Just lets out the most pathetic little whine you’ve ever heard in your life, then curls into a ball.
“..I came.”
.
You prop yourself up on one elbow, peering down at him. “Wait. Like.. just now? Untouched?”
He peeks from under his forearm, mortified. “Don’t laugh. I’ll actually cry.”
You bite your lip so hard it hurts. Shoulders shaking. And he groans, rolling facedown into the pillows.
“I hate you– shit, sorry, not you.. I hate my dick. Why’s it so loyal to you?–”
You poke the small of his back. “Satoru.”
“–betraying me all the time–”
“Satoru.”
He turns his head just enough to halfheartedly glare at you, cheeks flushed. “Yes?”
“Wanna fuck me?”
His whole body jolts up – dick included. The arm flies off his face so fast it’s comical.
“Hell yeah.”
Best Friend!Satoru who lines himself up with trembling hands. Rubbing the fat head of his cock between your slick folds once, twice, swiping up and coating himself in the mess he’s made of you. And he’s big – bigger than you expected – filling you up with a burningly good stretch. He bottoms out with a groan – long and low and wrecked. Forehead dropping to yours.
“Fuck. Fuuuuuck. Holy shit, you’re tight, baby.”
“Shush.”
He blinks. Pulls back. His eyes dart over your face – hesitant.
“Sorry.”
“It's okay, ‘Toru. Just give me a sec.”
“Okay. Okay, yeah– are you okay?”
You nod, slow. Silence fills the room.
And then his dick twitches, and the both of you burst out into laughter.
It’s awkward. In that best-friends-really-shouldn’t-be-having-sex way. But that’s what makes it fun, no?
And god, Satoru thinks he loves you.
He likes when you smile. He likes when you say his name. You’re really fucking pretty all the fucking time and even more so when you’re giggling – something in the frequency of your laugh making his brain short circuit to a pleasant buzz. And when you give him the green light, the buzz spreads all the way down into his chest, into some funny fuzzy feeling that makes his stomach do flips.
Best Friend!Satoru who fucks you like he’s trying to crawl inside your skin and live there forever. Slow, reverent, hips rolling deep and deliberate like he’s trying to mold your walls into the shape of his cock with every inch. His forehead stays pressed to yours, breath hitching every time he bottoms out, those ridiculously blue eyes all wide and adoring and completely fucking gone.
“Shit.. shit, you feel–” he cuts himself off with a shuddering groan, pulling out slow just to watch the way your pussy clenches around nothing, desperate to drag him back in. “You’re sucking me in, baby. Greedy little thing.”
Best Friend!Satoru who can’t decide where to put his hands. They’re everywhere, frantic, like he’s scared you’ll vanish if he stops touching. Gentle against your tits, sliding down to frame your hips, then up again to cradle your face while he kisses you all sloppy and open-mouthed, tongue swirling with yours like he’s starving.
And then his eyes flutter open, and he murmurs soft against your mouth – “the clitoris.”
“What?”
He smiles bright, hand drifting down to thumb at your puffy clit. Grinning wider when your head falls back against the pillow and your toes curl and you squeal his name.
“The clitoris.”
Best Friend!Satoru who loses the plot completely when you wrap your legs around his waist and pull him closer. The rhythm stutters, turning all messy and desperate, and he pants into your neck, hips snapping hard enough that the headboard smacks the wall with a steady thump-thump. But his hand cradles your head gentle, the other supporting your waist. So, so careful.
“Wait– fu– fuuuckk, m’not gonna last if you keep–”
He chokes on the words when you clench deliberately around him, walls milking his cock.
“Shit, cumming, baby–”
Best Friend!Satoru who tries to pull out. Because he’s a gentleman (allegedly). But you lock your ankles behind his back and your arms wrap around his shoulders as you hold him tight to your body, murmuring a quiet “inside. on the pill” – and he’s gone. Eyes rolling back so hard you’re worried for a second, before he slams back inside with a guttural sound. Hips grinding deep as he spills all hot inside you.
He cums forever. Like, literally. Forever. You didn’t know a guy could cum this much. Pulse after pulse, hips jerking helplessly, face buried in the crook of your neck as he whimpers, muffled against your skin. “Fuck, fuck, take it– take it, baby, shiiiit–”
Best Friend!Satoru who stays buried inside you the whole time. Cock still half-hard and twitching every few seconds like it’s raring to go. Trembling, sweaty hair sticking to his forehead, peppering gentle kisses along your collarbone as the silence spills soft between the two of you.
And then he pulls out, slow. Watches his cum drip out of you with a loving sigh. Proceeds to scoop it all up with two fingers and push it back in, smiling when your walls flutter weakly around his knuckles.
“Mine,” he whispers. Rolling your clit beneath the pad of his thumb almost absentmindedly. “All mine.”
Then he flops on top of you like an overgrown cat, face smushing between your tits, arms wrapped tight around your waist.
Best Friend!Satoru who, five minutes later, is hard again. Nudging your thigh with his dick like a golden retriever ready to play.
“Round two?”
You flick his forehead. “You just came inside me like a broken hose, Satoru. Give me five minutes.”
He pouts. Then brightens.
“Cool, I’ll use the five minutes to motorboat you again.”
“Satoru–”
“Brrrrrrbrrbprbrpbrrrrrr.”
Best Friend!Satoru who swears he’s not perving. Surely not.
Best Friend!Satoru who absolutely is.
But he’s doing it respectfully!
Quietly.
Desperately.
In the stupid way stupid guys do when they fall in love with their stupid childhood best friend.
(Satoru is NOT cutting off his balls for this.)
