Oddly enough, Shouto pops the question when he's balls-deep inside of his cute, angry little boyfriend. He's got him on all fours, holding him steady by the hips, every thrust of his thick cock met with the most adorable high-pitched whines, the sweetest baby whimpers.
God, Katsuki was so cute.
But he was biting on his hand—again, this wasn't the first time—in an attempt to be quieter. Katsuki was usually too proud to scream all-out, even when he had tears in his eyes because Shouto's fat dick fit so snugly inside of him, filled him up and fucked his little boy pussy so good it was unfair.
He was biting hard enough to break skin, Shouto notices, thrusts losing a bit of their momentum to focus and stare silently. Katsuki's sharp canines scraped across the flesh of his palm in an almost violent manner, blood drawing as his third layer of skin splits at the pressure, too weak to hold up. He was drooling all over himself, too, brows furrowed upwards as he sniffled softly and tried his hardest not to cry.
"Damn it, fucking—fuck, fuck—" Katsuki squeaks angrily into his hand, still biting down on his own flesh as Shouto shoves his hungry cock inside him even more aggressively, now, making sure his heavy balls slap against Katsuki's ass cheeks every time he slams in, if only to draw an even bigger reaction out of his boyfriend.
"Katsuki," Shouto starts, in that dead-pan voice of his, expressionless. His fat girth is still buried deep inside his boyfriend's cute butt, throbbing eagerly. "I've been thinking about this for a while... are you a masochist?"
Katsuki snaps his head towards him, quickly, so quickly Shouto wants to pet his head because he looks like an angry puppy. But that's also how Katsuki always looks, normally—to Shouto at least. He finally lets up on the death grip his teeth imposed upon his hand, a thick line of drool connecting from his swollen lips to the outer flesh of his palm. Shouto's eyes flicker downward to stare.
Katsuki's face burns red, a rosy blush settled high up on his soft cheeks. "Wha—!"
"—You're always biting your hand." Shouto interrupts, calmly, genuinely curious. "Doesn't it hurt?"
Katsuki is quiet for a bit, then, the only sounds present his cute little whimpers and the fast, hollow slap of Shouto's hips repeatedly slamming into his plushy ass. Shouto persists, leaning forward to rest his upper torso up against Katsuki's back, whispering in his boyfriend's ear, softly, "So, are you? Do you like a little bit of pain?"
"O-Of course not!" Katsuki's outburst is immediate, laced with disbelief and screamed loudly into the silky fabric of their bedsheets. His voice cracks. His face has gone even more red. "Don't go casually saying shit that makes someone seem like a pervert, dumbass!"
"Really?" Shouto keeps his dead-pan expression, unimpressed and unaffected by his boyfriend's harsh shouting. Large hands leave Katsuki's hips for a moment, sliding up the smooth flesh of his baby's tiny waist, up past Katsuki's six pack until they're resting on the soft expanse of two plushy tits. Shouto's fingers ruthlessly clamp down on Katsuki's cute pink nipples with absolute purposeful intent for it to be painful, twisting the two defenseless baby nubs and pulling them outward violently.
"Ahh! S - Shou- Shouto, you bastard—" Katsuki whines his name pathetically and lets out a sweet, sweet moan, all shaky and high-pitched as his back curves into a beautiful arch, the squishy flesh of his ass cheeks pressing up against Shouto's dick where it's still swollen and pulsing inside of his boyfriend's trembling pussy.
"Looks like you are." Shouto states, factually. He lets go of Katsuki's poor baby pink nipples and allows him to gasp in a breath.
"I- I told you—it's not..." Katsuki begins to protest, getting interrupted by his own soft whimpers when Shouto slides his fat cock out of his pussy, dripping wet with Katsuki's delicious juices and sticky with lube. He buries himself all the way back inside with one single thrust, and then another, and another, each one filling his eager pussy up better than the last, and Katsuki feels tears well up in his eyes again, it was so fucking unfair, "it's not like that! It's not..."
Shouto stays silent, takes a good, long look at his boyfriend's face, hips thrusting absentmindedly as he's deep in thought.
His next decision is made on a whim.
And Katsuki doesn't even see it, too busy trying to fill his lungs with air and calm his rapidly beating heart to notice as Shouto raises a hand, still wearing that dumb blank expression on his face—and spanks him smack across the ass, hard, a full palm and five fingers coming down on both of Katsuki's cheeks so roughly they jiggle back and forth at the force of the hit, and an aching slap is protruded throughout the room.
Katsuki's mouth opens wide in a desperate forced wail, crying out like a newborn baby, hot tears finally spilling over as pretty scarlet eyes go unfocused and his cock squirts steaming cum into a steady puddle of shame between his legs.
Katsuki's forehead is pressed into their comforter, he's shaking, mouth open, panting softly as he sniffles. Teary eyes stare on, wide and absolutely mortified at the sight of his own cock as it continues to spurt out load after load of goopy thick cum into their bedsheets. He can't stop—he can't- it's not stopping, fuck—
Shouto feels his dick throb where it's still snuggled tightly inside Katsuki's pussy. His breath hitches. It suddenly feels hard to swallow.
He came so hard... from just that...
Shouto is still contemplating the next day.
He's in class, chin resting idly on his hands. He understood the situation fully now. Katsuki liked pain. He had always thought it was strange, initially—especially now, looking back on all the times Katsuki would hiss an angry little ouch into thin air, whenever Shouto was clumsily rough. Shouto would apologize—genuinely, of course. But Katsuki's face, afterward, now that he thinks about it, would always be so flushed and sated, rather than angry and frustrated like it was when he was actually upset about something. He would get all teary eyed and whiny and look so ruined, so delectable. So... adorable.
Shouto feels his heart quicken, just the slightest bit. He was excited. Katsuki is a masochist...
Shouto is so deep in his thoughts, he doesn't even notice Izuku and Ochako staring at him worriedly from a desk away. Nothing could pop his current bubble of love and concentration.
"A masochist..." Shouto mumbles to himself softly, staring off into space, a cute, healthy flush hugging his cheeks. Everything made sense now.
He takes out his phone and begins typing away. Preparations had to be made.
The next time he has his tongue shoved down Katsuki's throat, Shouto brings it up.
He's in the middle of devouring Katsuki's cute mouth, tongue soft as it pushes inside to caress along the backside of Katsuki's upper lip and the top row of his baby's teeth, licking behind them, too, prodding at the soft flesh of Katsuki's inner cheeks. It's so warm.
Katsuki obediently keeps his mouth open for Shouto to play around with and thrust his tongue inside of, whining softly against his boyfriend's lips at a particularly hard lick, blushing pink all the way down to his neck. His boyfriend was so cute, Shouto sighs.
"Katsuki," He murmurs, mouth smacking together nice and slow as he catches and pulls Katsuki's wet tongue in between, thoroughly making out with his boyfriend's delicious, kiss-swollen lips. "I wish to try something today."
Shouto feels his boyfriend stiffen against him, just slightly, Katsuki's eyebrows drawing together anxiously. He makes this little confused sound at the back of throat, hesitantly meeting Shouto's mismatched eyes. "What is it?"
Clank, clank. Click.
By the time Katsuki looks down, it's too late. There, around both his wrists sits leather buckled handcuffs, held together by a small metal chain. Dread and something else begins to burn hotly inside his tummy.
What the fuck.
"The fuck are these?" It comes out as a lost sort of whimper. Katsuki means to sound more terrifying, he swears. He's just in shock.
"S&M goodies," Shouto says, simply, eyes bright and innocent. He seems so proud of himself. Katsuki exiles his heart to torturous execution for thinking Shouto looks sort of cute, in this moment. Handcuffing him.
What the fuck, his mind repeats, helpfully.
"Fuck, Shouto, where..."
"Amazon has everything and ships really fast. Kirishima told me so."
It's only then that Katsuki notices the entire box of- of S&M goodies, sitting at the foot of Shouto's bed. And the pretty bastard has a rope in his hands, now- where the fuck—
"What would you like to start with?" Shouto asks this casually, as if he was talking about what Katsuki wanted in his morning coffee and nothing else. He leans over his boyfriend's crouched frame, still holding the considerable length of rope.
Katsuki flinches back, instinctively, cheeks flushed and eyes wide with disbelief. "Wh- What the hell are you even talking about—"
"—Do not worry, Katsuki." Shouto stares at him, completely serious, one hand shuffling around in the box of goodies behind him. "If you are the M, I shall be the S!" He points to himself with his thumb dramatically, looks so goddamn proud of himself, like some fucking loser.
"Even my name is Shouto, see? It's S."
...That's it. He wants to die. Where is the nearest tall building. "What kind of shitty logic is that—"
Katsuki is so mind-fucked he doesn't notice Shouto coming closer towards him, reaching out for his face. Before he's even gotten the chance to process - process anything, fuck—everything in his line of sight is dark. Pitch black. A void.
"I-I can't see—"
"It's a blindfold."
...Of course. Of-fucking-course.
And then there are two large palms, warm, soft on either side of his face, pulling him inward. With his sight gone, Katsuki feels Shouto's tranquil presence even more strongly, taming him, just the slightest bit stubborn, still, when he feels his boyfriend press his mouth up against his again. He wasn't going to just open up and spread his legs like the other time—he refused, damn it.
Don't think you get to just do whatever the fuck you want, you ass. Like I'm that easy, like I'm that fucking...
Shouto licks a firm path up Katsuki's stiff lips, nibbling softly on his baby's bottom lip, catching it between his teeth and pulling, calm and expectant as Katsuki gasps sweetly and opens his mouth nice and wide for him. Such a good boy. Shouto hums softly and thrusts his tongue in deep, letting his saliva pool and drip into Katsuki's awaiting mouth.
...in love... with you... fuck...
Shouto delves his tongue inside Katsuki even deeper, stretching as far as it's able to go, laying it flat inside Katsuki's mouth and turning his head to angle their mouths even closer together.
Shit, fuck- fuck everything, god damn it...
Katsuki holds back an embarrassingly loud whine when Shouto begins to gently suck on his tongue, hating the way his traitorous mouth tries to open itself even wider, even bigger, so Shouto can have more access to lick at wherever he wants. Touch wherever he wants.
The feel of his tongue... it's so vivid with the blindfold, shit...
There's that feeling, burning hot inside his tummy again. Shouto finally lets up, smacking their open mouths together once, twice, before he's pulling away, and Katsuki doesn't even need to see to imagine the thick trail of spit connecting at the tips of their tongues. He feels Shouto slurp it up without an ounce of shame, his boyfriend pecking him softly on the lips one last time. Katsuki's limbs feel like jelly, and his heart feels ready to give out. Would... would it really be so bad to just let Shouto take care of him? Just this once?
This is bad... this is so fucking bad...
Shouto licks his lips, gaze half-lidded. Katsuki was very docile with his eyes covered. Cute.
With steady and calming fingers, Shouto guides his boyfriend's cuffed hands upward so that they're held above his head, spreading out Katsuki's crouched frame. He grasps softly at the hem of his baby's black t-shirt and pushes it up until it's just below his nipples, revealing the cute band of Katsuki's underwear, his small waist and muscled tummy.
"This will be cold," Shouto murmurs quietly. "But hang in there, okay?"
Katsuki, again, can't even process what's happening, not until he feels the sensation of something chilled and sticky being squirted directly onto his stomach, coming out in thick globs.
Katsuki gasps, whimpering loudly, and his eyes go wide underneath the blindfold. "Wh- What did you—"
"—It's lotion." Shouto replies, as calm as ever, setting the bottle down as his hands make quick work of rubbing the creamy substance into Katsuki's baby soft skin. "How does it feel?"
"It's... slimy..." Katsuki tries to keep himself from squirming too much, letting out a high squeak, back arching when cold fingers suddenly squeeze at his nipples, unforgiving. Shouto's palms cup at the sides of his pecs, bunching them together so they somewhat resemble tits, and he teases the tips of Katsuki's nipples, fingers rubbing back and forth at the pink nubs, tugging, pressing, pulling.
Katsuki feels like he's going to lose his mind, a series of whiny ah, ah, ah coming out of his mouth.
Wh... What is this? I can't tell where he's going to touch next... I can't do anything but focus on where he's touching...!
Katsuki lets out a moan at a particularly harsh tug, nipples fondled raw, already panting softly. His heart is beating fast, so loudly all Katsuki can hear is the rhythmic pulse of blood pounding in his ears. Underneath the blindfold, wide eyes begin to well up with tears. He was shaking. It felt so good, what was happening to him?
I'm becoming weird...!
"Katsuki," Shouto says his name so tenderly. He's got one hand resting atop his baby's tummy, the other holding the supple flesh of an upper thigh. Greedy fingers pull down the band of his baby's soaked underwear, cold air hitting Katsuki's swollen cock with a biting sting. Katsuki curses internally. When had this fucker taken off his pants?
"Down here, it's gotten amazing." Shouto runs a single fingertip down the length of his boyfriend's leaking cock, from balls to tip. Katsuki startles, whimpering softly. His face burns.
"Sh- Shut the fuck up!"
He bites the words out venomously, too embarrassed to think of a better come back, but suddenly Shouto is leaning over him again, pressing their bodies together nice and slick, whispering so closely into his ear Katsuki can feel cool breath on his neck. He shivers, suddenly feels so small.
"Tell me honestly, Katsuki," Shouto's deep, soothing lull is unfair, it's unfair, unfair, un-fucking-fair. "Between gentle... and rough..."
A thumb hooks at the bottom of his blindfold, pulling it upward, exposing just how ruined Katsuki is for the world to see, from the darkened candy apple flush of his cheeks, to the pathetic tears in his eyes, to his open mouth leaking drool. He was a mess.
"Which do you like better?"
Katsuki breaks their gaze, he won't look at Shouto, he can't look at him, feels too mortifyingly defeated at how his vision begins to blur over, even without the dumb blindfold. He wasn't going to cry. He was not.
But his heart feels like it's being crushed at every soft pant of breath he lets out, and Katsuki bites down hard on his bottom lip, eyebrows furrowing together, frustrated as he sniffles quietly and in the softest, most vulnerable voice, tells Shouto.
"A... A little rough."
Shouto freezes up, for a split second. There's a faint blush on his cheeks, and his chest feels tight because Katsuki is too cute, god, he's so in love.
"Well then..."
With a firm grip on either of his baby's thighs, he's spreading Katsuki open wide for him, his boyfriend's needy cock still reddened and leaking pitifully between his legs. Shouto slides a hand down, fully presses two fingers along Katsuki's dripping pussy, rubbing at it lewdly so that it makes these embarrassingly wet squelching noises. Katsuki's whines start to get louder.
"What would you like to go in here? Fingers? Or something else of mine?"
"Ahh- Shut- Shut up, you're so fucking- ah, ah- annoying, god," Katsuki tries his hardest to keep face even with two naughty fingers rubbing circles into his aching pussy, teasing him, threatening to push inside but never actually following through because his boyfriend was a fucking sadist for the day, apparently. Fuck Shouto if the bastard thought he was actually going to- to do something so humiliating as beg for his cock, Katsuki would never.
"If you don't say anything, we're going to keep staying like this." Shouto looks down at his boyfriend, unimpressed. Katsuki was getting fussy. This wouldn't do.
As Shouto expects, the other stays silent, even going so far as to squirm around and bring his cuffed hands down from above his head.
"Katsuki," Shouto tries, softly, pulling his fingers away. He's met with an even whinier baby at that. Shouto clicks his tongue quietly. "Hey—"
"Fuck you!" Katsuki shouts, he can't help it, why did the bastard stop touching him, Katsuki couldn't even touch himself with his hands all tied up and shit like this it just wasn't fucking fair, "J- Just shut the fuck up and put it in already!"
Katsuki is about to say one more thing, already has the breath in his lungs ready to go, but that air is soon cruelly knocked out of him when Shouto slams a palm down onto his chest, firmly, forcing him to lay back down and be good. And when Katsuki looks up, timidly meets his boyfriend's gaze, he stiffens.
For once, Shouto didn't have that calming, stupid dead fish expression on his face. In fact, he almost looked angry, with how he loomed over Katsuki's helpless body, mouth set in a line, eyes dark.
"That potty mouth of yours just can't seem to beg correctly, huh?" Shouto finally lets up on some of the pressure he was laying on Katsuki's chest, sighing softly, looking so disappointed. His voice is cold, ice cold, and Katsuki feels himself shiver under the pure authority it seemed to demand. He felt like a puppy, being scolded with his tail between his legs. Shouto's next words make his cheeks flush.
"You deserve a punishment."
Shouto's punishment was fucking him until he cried, it seemed.
"Ahh—uagh- Shou- Shouto, nn—" Katsuki sobs at the absolute heavenly feeling of having his trembling pussy filled up and stretched out, cuffed hands clutched tightly into his chest, mouth open wide and leaking drool all over himself as he gasps and whines over his boyfriend's cock. Shouto's got him on his side, legs spread with one of Katsuki's thighs hooked over his shoulder to use for momentum to slam in. He's in complete control, thrusting his cock in and out at a brutal pace, fucking Katsuki’s wet pussy so good on his big fat dick.
Shouto rests his cheek against the smooth flesh of Katsuki's inner thigh, affectionately watching on as the thick girth of his cock gets swallowed whole and repeatedly disappears inside Katsuki's body over and over again, hugged tight by his baby's needy pussy. "I'm really deep inside you, Katsuki."
At this point, Katsuki can't even salvage enough of his voice to curse back, simply curling into himself on their bedsheets, only able to pant harshly and let out little baby whimpers as he chokes on his own sobs and is absolutely incoherent while having his pussy pumped so roughly with Shouto’s fat cock. In, out, in, out, rough, harsh, so deep inside him he feels Shouto's sweaty balls slap against his pussy at every thrust.
"Face me," Shouto murmurs, sliding Katsuki's thigh down from his shoulder and laying his baby flat on his back instead, stretching both of his legs far, far apart so he can fit himself in between and force Katsuki's eager pussy down further onto his dick. Cold hands push up at Katsuki's t-shirt again, raising it above his nipples so Shouto can latch on with his fingers and pinch the pink nubs roughly, enough to hurt.
"Ouch!" Katsuki cries out loudly, throwing his head back, tongue finally finding the strength to form real syllables at the heady shock of pain.
Shouto hums, forcefully pounding his baby’s scrumptious pussy raw as it slurps and contracts around him, gripping onto his cock like it never wanted to let go. "When it hurts, your pussy squeezes really hard. It's cute."
The hold Shouto keeps on his nipples is tight as he fucks into him, pinching down even harder the second time, pulling hard enough to break skin.
It feels so good, it feels so fucking good, fuck, fuck fuck -
"Agh- no, I- I'm going to- " Katsuki weeps, voice breaking, nipples twisted raw, wrists bruised, and pussy completely stuffed full with Shouto’s pulsating cock as it mercilessly thrusts inside him and continuously fills him up. He gasps softly, can't help the tears that spill over as he buries the side of his face into their mattress and helplessly babbles with his tongue lolled out, drool dripping from his mouth in copious amounts, "I- I'm com..."
"Wait."
Shouto stops, the motherfucker actually stops, fat cock still fully seated deep inside Katsuki's pussy. Katsuki absolutely whines, not giving a single fuck anymore, throwing his head back like a spoiled baby not getting what he wanted. He wouldn't be surprised if there were actual buckets of tears streaming down his cheeks.
"I told you this was a punishment, right?" Shouto's tone is comforting as he grabs at the base of his boyfriend's leaking cock, firmly, enough to keep him from squirting cum all over the place. It's painful. "Not until you say I'm sorry."
"S- Screw you!" Katsuki wants to cry. He wants to kick and scream and demand that Shouto give him what he wants, damn it, but even so, his voice had come out weak and needy. He was so desperate, fuck. This wasn't fair... It wasn't-
"Katsuki," Shouto's leaned in close to him, again, and he's got a hand lovingly threading through the soft strawberry blonde of Katsuki's hair, coaxing his baby boy to look up at him. The worst part is, Katsuki doesn't even look mad. No, he looks devastated, red in the face as he sniffles and shyly meets Shouto's eyes.
"Shouto, I'm sorry, say it." He commands softly.
Katsuki whimpers in defeat.
He turns his head to the side, completely and utterly wrecked, breathing in and out in harsh pants as he swallows down his pride and starts to whisper, so quiet it was clear the words were only for Shouto's ears and no one else's.
In this moment, Katsuki looked very cute.
"Shou- Shouto, I... I'm sor- ... I'm sorr—"
Shouto really should have waited for the last syllable, he could have—probably. But all the times Katsuki has told him to die and eat shit had suddenly flashed inside his head, and at the utter contrast of what was happening now, his heart couldn't take the level of cuteness and love he felt. It was too much.
And so, Shouto cuts Katsuki off, rudely, mid-sentence, slowly sliding the fat length of his cock out of Katsuki's trembling pussy until just the head is stretching him open, grabbing hold of his baby's thighs, and then slamming his big cock back inside so aggressively Katsuki gags as tears fill his eyes and he cries out loudly, scream unbelievably needy and high-pitched as he cums, cute little cock squirting messy globs of hot semen all over his own chest and t-shirt, spurt after spurt, until his balls had nothing left in them.
Shouto stares with glazed over eyes at the beautiful scene in front of him, but doesn't stop for a second, cock still hard and throbbing inside Katsuki's pussy and chest overflowing with the overwhelming amount of love he feels as he leans forward to undo Katsuki's handcuffs. His blank expression is dead serious when he asks, "You can still keep going, right?"
Katsuki is so exhausted and out of it, whimpering softly with sticky tears and snot all over his face he doesn't understand what's happening. Shouto lays back, resting his head against their bed pillows. He grabs at his baby's now free wrists and pulls Katsuki on top of his lap until he's sitting in a riding position and bouncing up and down on the big pulsating cock in his pussy like a good boy.
"W- Wait—" Katsuki chokes out, resting his hands on the comforter behind him, back arching, pushing his tits out and mewling like a small kitten when Shouto grabs hold of his tiny waist and begins lifting him up off his cock and then dropping him back down abruptly, using Katsuki's body weight to fuck his baby's pussy even more roughly onto his fat girth. Katsuki gasps, going cross-eyed, tongue out. "Just- came -..."
Shouto lets out a soft breath, takes both hands and slaps them down against Katsuki’s ass cheeks, squishing and bouncing the soft, soft flesh between his fingers before roughly yanking them far apart to spread Katsuki’s pussy open wide for him so it can eat up his cock to the very last inch.
Katsuki whimpers loudly at the feeling of being spread open and exposed, shaking from overstimulation, feeling dizzy like he's about to pass out. And Shouto is still thrusting into his pussy hungrily when he wraps a hand around Katsuki's over-sensitive cock, unforgiving as he uses the blunt tip of his thumb and stabs it into Katsuki's cum-leaking little cock slit, hard enough that Katsuki begins to see stars.
"Don't- ah—n-not with your nail—" Katsuki squeaks, pleading, words all slurred together and incoherent as drool continues to spill out of his open mouth. He felt like he was going insane. It felt so good he didn't want it to stop, he never wanted it to end. What was happening to him? "Ah, ahh—stop! I... I—"
"Why?" Shouto simply digs the tip of his thumb in harder, breath hitching at how unbelievably tight Katsuki's pussy repeatedly squeezes around his cock, clenching eagerly and begging to be filled up. He was really enjoying this. "You like pain, don't you? You—"
"—This..." Shouto freezes up, usually blank eyes going wide when Katsuki leans over from where he's sitting on his cock, pressing their chests together, reaching a hand out to clutch at Shouto's shirt for comfort. He's sniffling like a baby, full of tears and drool and he looks so vulnerable Shouto's heart can't.
"Something like this..." He whimpers softly, voice cracking in that unfairly adorable way it sometimes does. His bottom lip is trembling. "it's scary, Shouto...! What i- what if I can't go back to normal again?"
Ba-dum. Ba-dum. Ba-dum.
It takes Shouto a second to realize that the sound is just his heart, beating so loudly in his chest, so full of love.
Mismatched eyes go unbearably soft as they look at Katsuki, his baby, still hiccuping through his own tears, and it's instinctive when Shouto's arms come up to wrap around Katsuki's waist, pulling in tight, so tight until Katsuki collapses on top of him, the warmest and most loving of hugs. He feels like his heart is going to burst when Katsuki immediately goes to bury his face into the crook of his neck, sniffling and sobbing quietly while Shouto holds him. God... Shouto thinks, for maybe the ten thousandth time that hour. He's so cute.
Katsuki.
Shouto leans to sit up, rest his back against the headboard, arms still holding his cute boyfriend flush against him. He turns his head to press loving kisses into Katsuki's forehead, his cheeks, the crown of his head, basically anywhere he can reach, thrusting upward into Katsuki's gorgeous pussy and bouncing his baby boy up and down on his cock with a newfound vigor, powered wholesomely by how ridiculously in love he is.
It's okay... even if you can't turn back and can't be normal again.
Katsuki whines soft little ah, ah, ah, ah into the crook of his neck, whimpering nice and sweet when Shouto fucks him good until he's cumming again, squirting all over himself for the second time that night. He's breathing hard, each hot pant of breath huffing into the side of Shouto's neck, and he's squeezing his cute little pussy around Shouto's cock again, repeatedly. Squeeze, squeeze, squeeze.
Shouto feels his breath hitch, feels his massive sweaty balls tighten up, engorged with all the thick goopy cum being held inside them, load ready to be let out and pumped into Katsuki's tight needy pussy until his baby's tummy gets all bloated filled up with Shouto's sweet thick release. It's not long before Shouto is spreading Katsuki's legs wide open for him and shoving his fat cock the deepest inside Katsuki's pretty pussy he can manage, big mushroom cockhead fitting itself inside snuggly, fat dangling balls fully pressed up against Katsuki’s ass cheeks as Shouto finally lets all his cum gush out of his cock and shoot straight into Katsuki’s sweet heavenly pussy with a soft moan and a quick, desperately murmured, "I love you, I love you, I love you."
Katsuki gasps and whines brokenly, back arching, wailing with tears rolling down flushed cheeks as Shouto’s fat cock pumps steaming hot cum into his pussy non-stop, heavy milk stream filling Katsuki up good, so good, until his tummy feels unbearably warm, pussy absolutely spent and filled to the very brim with Shouto’s hot, delicious thick cum, so much that it overflows out of him. He felt so good, so fucking full.
Faintly, he feels Shouto press a last kiss into his temple, hears his own voice croak out a soft love you... I love you before his eyes roll back and everything gets fuzzy and Katsuki can only assume his body finally passed the fuck out, about damn time. He wanted to sleep for the next ten thousand years. Filled up with Shouto's cum and suffocated by love.
Shouto hums a quiet melody, gently easing his softening cock out of Katsuki's well-stretched, cum-filled pussy and laying his exhausted boyfriend down so that his head is resting on a couple pillows, standing up to get a washcloth. Katsuki's soft snores make small bubbles of laughter rise up in his tummy.
Because for you, I'll always...
