Work Text:
Katsuki tries to focus on the prayer meeting. He really does, but it’s so fucking hard when all he can think about is the mind-numbing and hot sex they indulged in last night. His throat is still sore from being roughly fucked into, the weight of Deku’s huge cock and the taste of his cum vividly burned into his whole being. His hole suddenly feels very empty, also remembering the way Deku split him open on his dick, fucking him and not letting up till he was cumming dry.
Deku’s parents were out and he’d invited the other boy over under the pretence of doing bible study like good little religious boys, and well, why read verses from the bible when they could be having hot, steamy sex instead?
He had fucked Katsuki raw, had filled his ass so much that the blonde could still feel his thick seed in his guts.
Fuck, he really should be paying attention.
Katsuki sings along with the hymn he knows byheart, the words flowing from his mouth even though his mind is completely elsewhere.
“Kacchan—baby, you’re so good for me,”
“Yeah, take it. Fuckin’ made for this, weren’t you?”
“Look at how your hole swallows my dick,”
Katsuki squirms in his place, body sweating the more time passes and the more worked up and heated he gets. Deku’s voice is still ringing in his ears, his praises ingrained into the very depths of his body. The phantom feeling of his dick filling Katsuki’s ass and pounding into him has blood rushing quickly south, his cock filling up slowly as his mind feeds him images of sex and Deku and different sorts of lustful temptations one after another, all while his mouth sings praises of the Lord.
“Oi Katsuki, why aren’t you saying the prayers? Stop getting distracted, will you?” Mitsuki says, side-eyeing him in disdain. He clears his throat nervously, willing the sinful thoughts away. His pants feel a little tight around his groin and he discreetly looks down, and yep, that’s definitely a half-chub he’s sporting.
Katsuki takes a deep breath and forces all thoughts of Deku and his stupid freckles and his stupid smile and his big dick out of his brain.
“Who knew Kacchan would be such a slut for cock.”
Well, it can’t be helped.
He looks up at the statue of Christ on the cross and his lips curl into small grin.
“Mom, I’m just going to go to the bathroom real quick. I’ll be back in a few,” he says, smiling at her like the gentleman he is. His mom nods and he excuses himself, quickly adjusting the crotch of his pants so his semi-hard dick isn’t too visible.
Satan wins again, huh. Sorry, old man up in the heavens, maybe I just wasn’t made for resisting temptations, he thinks in glee as enters the stall and takes his dick out, jerking off to the thoughts of one green-haired freckled idiot.

“Deku—”
“Mhmmm, Kacchan, I missed you,” Izuku coos into his neck, loosening the tie around Katsuki’s collar and tugging it down, pressing a kiss to the hot skin there, taking it between his teeth and biting down, making Katsuki grunt tightly. He shoves his hand beneath the blonde’s dress shirt, running his fingers along his back and down to grab his ass and yank him closer.
Izuku pushes his lips onto Katsuki’s in a bruising kiss just as he grinds his hard length against the blonde’s. Katsuki gasps wetly against his lips, moaning into his lover’s mouth while he sucks Katsuki’s bottom lip and ruts their clothed erections together.
They can’t be too loud, the distinct sound of the organ playing reminding them about the service they have to attend. Quickly, with deft fingers, Katsuki reaches down and unbuckles Izuku’s belt, pulling the zipper down and shoving his hand in, arousal shooting up his spine at how hard and huge and thick Izuku is.
“All I think about is how much I want to be fucked by this big cock of yours,” Katsuki pants, rubbing his palm against the length and grabbing it through the boxers. Izuku hisses when Katsuki thumbs the head and sucks on a patch of skin on his collarbone, low enough to be covered with his shirt.
“Kacchan, wanna fuck you so bad, wanna fuck your tight ass till you’re begging for me to stop.” Izuku growls, fingers burying in blonde locks and yanking him up so that their lips meet again, wet and slick. He pushes Katsuki back further so that he’s pressed against the wooden wall of the confessional, wedging a strong, thick thigh between Katsuki’s legs and angling it upwards to press against the blonde’s erection.
“Yeah? Gonna give me your dick right here, Deku?” Katsuki grins, breathless and sweaty as he humps down on Izuku’s thigh. “Wanna know how much I’ve been aching for it?”
Izuku makes a noise in the back of his throat, rubbing his thumb on Katsuki’s nipple over his shirt, making the blonde hiss lowly. “Tell me,” he says, voice half demanding and half pleading.
“Woke up feelin’ so fucking empty, had to stuff in four fingers ‘cause I was so fucking horny and it still wasn’t enough,” Izuku whines, nipping on his neck and urging Katsuki to continue. “Kept fantasizing about it during every sermon and prayer group, imagining everyone’s faces as they watched you fuck me over the pews and table.” Katsuki finishes, pushing Izuku’s slacks down to his ankles and wasting no time in grabbing his ass and pulling him in more.
Holy shit. The thought of bending Katsuki over one of the wooden benches and mounting him in front of all those religious people, in front of the Saviour while He looks down at them, shamelessly pounding his boyfriend and breaking every law written in the holy book, that very thought has Izuku almost to the point of creaming his pants already.
He does the sign of the cross and mutters out an Amen in his mind because Jesus fucking Christ.
Katsuki laughs breathlessly at Izuku’s mumbled whisper of their God’s name, pulling him in for a wet kiss as he yanks the freckled boy’s boxers down. Izuku’s dick springs free and the very sight of it puts Katsuki in a hypnotic trance. His hole clenches and throbs, wanting nothing more than for Izuku to just shove it deep inside and fuck it into him. He wraps his fingers around the throbbing length and gives it a nice, slow stroke, from base to tip, circling the wet head with his thumb and squeezing the shaft teasingly. Izuku groans, dropping his head down to Katsuki’s shoulder as his hips jerk forward involuntarily.
“Give it to me, Izuku. Want it so bad, want it all the fucking time,” Katsuki whispers into Izuku’s ear, biting the cartilage and running the tip of his tongue along it. His fingers keep sliding over Izuku’s dick, spreading precum along the shaft and reaching down to play with one of his balls.
Something snaps in Izuku. Whether it’s because of the way Katsuki’s been fantasizing about him every day, or if it’s how Katsuki allows Izuku to fuck him sloppy everywhere; in their rooms when their very Catholic parents are downstairs having no idea that Katsuki’s choking on his dick, or fucking in the toilet of their very Catholic all-boys school in plain daylight where the nuns could catch them anytime, or sneaking off to somewhere private just to have wild, rough sex when they should be raising money during charity fundraiser campaigns.
Izuku pulls his head out of Katsuki’s neck and slams his lips against the blonde’s, pushing his tongue in when his baby’s sweet mouth drops open pliantly. He runs it along every wet crevice, sucking and nipping on Katsuki’s own tongue like it’s the one thing keeping him alive. “Fuck—you’re so damn needy,” he growls in between their heated kiss, pushing Katsuki’s slacks and boxers down to his thighs, spreading his asscheeks, running his finger along the crack and dipping inside.
It’s wet and loose already. Izuku’s chest and groin heat up at the image of Katsuki fucking himself on his fingers, imagining Izuku doing it to him. His cock gives a violent twitch in Katsuki’s grasp, more precum beading and running down the shaft.
“See how wet I am for you, baby? Got myself all nice and stretched just for you.”
“Sweetheart, did you finger yourself this morning before coming for mass, hmm?” he asks, thrusting two fingers inside and twisting them, the pads scraping against the soft walls and making Katsuki whine and nod. “Kacchan’s such a naughty boy. You wanted my cock to be filling you up instead of your fingers, didn’t you?”
Katsuki nods again, whimpering in pleasure when Izuku scissors the digits and grinds them in deep mercilessly. “Yeah—fuck Izuku, nothing compares to your dick. It’s so big and it fills me up so well, baby. I need you in me right now,” he pleads, planting his lips on his boyfriend’s in a sweet kiss.
“Kacchan...”
It takes everything in Izuku’s will to calm himself down so that he doesn’t bust a nut right then and there. Katsuki just knows how to rile Izuku up, telling him all his depraved desires and praising Izuku, voice dripping with lust, thick like honey. His cute little noises coupled with the soft squelching of Izuku’s digits fucking his warm heat only fuels their lust more, like adding kerosene to an already raging fire, both boys growing needier and eager as the seconds pass by. Hands grab at each other and lips seal together in hot, wet kisses as they climb up new heights of sinful temptations together.
“Do it, fuck me Deku. Fuck me so hard that it’s all I can think about when I’m on my knees praying,” Katsuki pants, clenching down on the fingers in his ass.
Izuku sends a silent apology to the man upstairs because he’s about to commit another grave sin.
This is exactly what he signed up for when he rebelled against his parents and the religion he was forced to follow, when he broke his vow to save his virginity for his wife, when he broke his vow to his God and swore in His name to fuck Katsuki so hard he forgot every prayer and every verse from the bible, till he screamed Izuku’s name and came on Izuku’s cock alone.
Izuku’s patience shatters like glass and his mind completely zeroes in on the tempting little devil in his arms. Said ‘devil’ looks like he just won the damn lottery, red eyes twinkling and lips pulled back in a naughty grin.
Damn it all to hell. If Kacchan wants to be fucked like a dirty whore, who am I to say no?
Izuku pulls his fingers out and pushes Katsuki’s slacks down to his ankles, not bothering to wait for Katsuki to completely step out of it before he’s grabbing the back of his thighs and hauling him up, sweaty, trembling legs wrapping around Izuku’s waist. Katsuki’s black slacks dangle from one leg, dangerously close to falling off as he’s manhandled into a proper position. The confessional booth is small and suffocating with little space for their limbs to move comfortably and freely but Izuku still presses him back into the divider, also thinking about what would happen if one of the priests came in and caught them fucking like dogs in heat.
Izuku wraps his fingers around Katsuki’s wrist and brings his hand up, eyes dilating at the precum staining it. “Lick,” he commands, letting Katsuki’s hand go. Katsuki obeys, licking the cum away, making a show of sucking his fingers nice and slippery. “Get me wet, darling,” Izuku husks, green eyes lidding more when Katsuki smirks and takes his fingers out of his mouth, glistening deliciously with spit. He licks his palm too and reaches down between them, wrapping slick digits around Izuku’s dick, the precum and saliva making the glide smooth and easy.
Katsuki keeps his eyes on Izuku the entire time as he keeps sliding his fist over the throbbing length. The heavy weight and thick girth of it makes Katsuki bite his lip, arousal spiking hot in his groin. Izuku grunts and fucks into the hand curled tight around his cock, a quiet whine slipping out when the blonde leans forward and bites into the flesh of his freckled cheek.
“You’ll give it to me good, won’t you baby? Nice and rough, just how I like it.” Katsuki whispers against his face, breath hot and voice deep. Izuku turns his head and kisses his boyfriend, lips sliding over each other’s soft and wet.
He pulls away with a loud smack, resting his sweaty forehead against Katsuki’s, neatly combed green hair falling in unruly strands in front of his eyes. Izuku nods, barely suppressing a full-bodied shiver when Katsuki’s thumbnail digs into the slit. “Gonna fuck you till you fuckin’ taste me,” he snarls, Katsuki’s eyes widen for a second at the downright carnal look in his lover’s eyes before they relaxe into a lazy gaze, lips curling back into a devious smirk.
“Do it then. Fuck me like you mean it.”
Izuku makes a noise in the back of his throat and hitches Katsuki up higher, sweaty thighs slipping a little as the blonde balances himself. The space inside the confessional is only so much, and Katsuki’s neck is bent in an awkward angle, head pressed against the top of the booth and body curled over Izuku’s. It’s difficult with two well-built boys but if anything, it makes the sex all the more exciting and hot.
Izuku grabs his cock and brings it to his lover’s ass, rubbing the tip back and forth along the crack a few times. Green eyes lock with red ones, a spark of thrill passing between them, fire licking at his insides. Katsuki smirks mischievously, pushing and wiggling his ass down, Izuku’s breaths stuttering at the wanton display of lust.
Izuku’s so glad that he shifted to Katsuki’s hometown and had the chance to meet him all those months ago. He’s so fucking glad that the shackles of religion that were binding him down shattered that night which began with nervous touches and playful flirting and ended with Katsuki sucking him dry and Izuku eating his ass like a man starved to death. The very night that they were supposed to be reading the holy bible and praying to their Lord above like the good, religious boys their mommas taught them to be, they instead chose to damn it all to hell and embraced each other over and over, till they were physically aching everywhere.
They’ve committed so many sins together, hell, even falling in love with a each other was a sin that Izuku and Katsuki readily took on themselves, if it meant they could be with each other.
Katsuki wraps his arms around Izuku’s neck, his face clearly giving away how horny he currently feels. Flushed red, lips bitten and raw, nipples hard and cock dripping between their bodies. “Do it, ‘Zuku. Fuck me, please.”
He doesn’t have to be told twice. Lining his cock to Katsuki’s hole, Izuku pushes in slowly, burying inch after inch into the warm heat of his boyfriend, forcing Katsuki to feel everything, the blonde hyper focused on his ass being filled to the brim by his lover. “Oh fuuuckk—” Katsuki drawls, mouth opening in a slutty moan and eyes rolling to the back of his skull. Izuku keeps pushing his hips forward, till he’s in all the way to the base, hips flush against Katsuki’s ass. “God—yesss...” he hisses, feeling every raw bit and ridge of the hard prick stuffed in him, his hole twitching as Izuku’s length throbs and melts Katsuki’s mind in a puddle of lust.
Do not take the Lord your God’s name in vain.
“Jesus—Kacchan, you’re so damn tight—” Izuku groans, pulling out till only the tip is inside before slamming forward and burying all of his fat cock in Katsuki’s asshole. He gnaws at the blonde’s shoulder, teeth clamping down as he moves his hips back and forth, rutting inside his lover.
The moans that leave Katsuki’s mouth are breathless and low, trying to keep his noises of pleasure down as he’s taken by Izuku just how he wanted it, nice and rough. His body jerks underneath Izuku’s, knees trembling beside his waist. It’s so good, fucking in a place meant for absolving sins, tainting it with all sorts of unholiness and depravity.
The thrill and risk that comes with it. All of it adds to the need burning hot between them.
Izuku watches in delight as Katsuki is split open on his cock. Gasping, shuddering breaths escape his red, spit-slicked lips along with quiet whines and whispers of Izuku’s name. He rucks the blonde’s pristine white shirt up, now wrinkled because of Izuku’s frantic fingers. Taking a hold of Katsuki’s tiny, tiny waist, he squeezes the baby soft flesh hard, enough to leave bruises and handprints behind, ones that Izuku knows Katsuki will treasure. Said boy squeaks at the sudden pain that blooms from his side, his legs closing tighter around Izuku.
Katsuki buries his fingers in green hair and pulls, reveling in the way Izuku hisses at the pain. He gives a punishing thrust in retaliation, the force making Katsuki inch backwards. Izuku smirks against his boyfriend’s throat when Katsuki lets go of his hair to bite his knuckles instead as he tries to keep his voice from pitching higher when Izuku’s dick reaches so deep in him.
Izuku digs his nails in the soft skin of Katsuki’s sides and continues thrusting with unwavering desperation, hips rocking while Katsuki’s dick, slick and wet, rubs up against his abdomen. It’s incredibly hot in the small booth, Izuku’s fingers slipping when it glides along the equally slippery skin of Katsuki’s waist and hips, the scent of sweat and musk permeating the air. There’s something so erotic about it that it makes Izuku dizzy.
He imagines how they look right now in the cramped space of the confessional booth. Katsuki is hanging onto Izuku like his life depends on it, letting out breathy moans and whimpers as Izuku rails into him like there’s no tomorrow, hard and fast, indulging their young sex-deprived bodies in some good, sweaty lovemaking. The image makes Izuku drive into his boyfriend with renewed vigour, hips slapping repeatedly against the backs of Katsuki’s thighs.
However, the sound of the organ playing in hall reminds them that the service will start soon, and they only have a small window before it starts becoming suspicious and god forbid, their parents come looking for them.
Izuku speeds up his thrusts, lips parted against his boyfriend’s neck, licking the salt off his skin as Katsuki trembles and quivers under him, pushing his ass down as much as he can in the small space, whining into Izuku’s hair when the head of his cock slams against his prostate. “Fuck, ‘Zuku—” Katsuki pants, eyes squeezing shut as pleasure coils in his abdomen.
“Kacchan—” Izuku moans quietly, forehead plastered to Katsuki’s jugular, breathing laboured as he ruts into his lover, making sure to hit the bundle of nerves inside each time he presses in. Katsuki’s hole flutters and twitches around his length. Regardless of how many times they’ve done this, his hole remains soft and tight and warm. Perfect, just like everything else about Katsuki.
Katsuki has one arm wrapped around Izuku’s neck, the other reaching down to grab a hold of his hip, clinging onto the boy as he’s pounded into mercilessly. He drops kisses to Izuku’s hair and temple to keep his mouth occupied so that he doesn’t accidentally moan too loud. It’s so damn difficult, with Izuku’s big, fat dick grinding away at his throbbing walls and jamming against his prostate, his own erection rubbing up against the hard planes of his boyfriend’s abs, causing bursts of stimulation and making his whole body shiver. His nails scrape against Izuku’s hip, leaving red welts in their wake.
“Yeah—just like that. Harder, fuck—”
Izuku grips Katsuki’s thighs tighter and hitches him up more and gives it to him harder. The new angle makes the blonde arch and his mouth breaks out into a desperate string of moans and curses.
“Izuku, Izuku, ‘Zu—mmpphh!” Izuku quickly tilts up and muffles Katsuki’s loud and strangled cries of his name with his lips, capturing them and locking them away in the spaces of his ribs. He fucks the breaths and groans from Katsuki’s lungs, letting it fall unrestrained into his own mouth, the sounds resonating deep within his body and making his heart beat a little more fast.
“Ah, ah, ahhnn! ‘Zuku, please—”
“Sshh baby, quiet now,” Izuku murmurs against his lover’s plump lips, pulling out and slamming deep inside him so forcefully that it has Katsuki’s face crumpling into a sob and mouth lolling open in a silent scream, his eyes rolling to the back of the head. With every hard thrust, Katsuki’s body jostles and Izuku’s hand keeps slipping because of sweat. He grips the blonde’s thighs more firmly, nails digging into the soft skin. The action brings the sweetest and most pleasurable pain which Katsuki absolutely loves, evidenced by the way his breath hitches on a moan and his hole clenches around his lover’s dick. Precum smears against Izuku’s abdomen, it’s wet and messy and perfect.
Sounds pick up from the hall and they know they don’t have much time before the entrance hymns start. It’d be a real problem if they don’t finish and return back before the hymns.
Izuku paces up his thrusts, the whole booth shaking with the sudden increase in speed as he fucks into Katsuki recklessly, desperately, relentlessly. Hips pound into the body quivering underneath him, the blonde completely taken over with pleasure. The constant movement inside him drives Katsuki wild, his chest stuttering out breathless gasps and quivering groans the more he’s rutted into.
Lord, Izuku’s become addicted to this. The masculine scent in the air, the dick rubbing up against him, strong thighs bracketing his body, having a pretty boy in his arms, whining and being fucked stupid and sloppy on his cock. His dick hardens even further inside Katsuki who lets out a cute whimper when his hole is stretched more.
Izuku wants this to last, he’ll do everything in his hands to make it last. Izuku and Katsuki. Deku and Kacchan. That is how it’s going to be.
Heaven and hell both know he’s not going to let a religion come in between them.
“Touch yourself, Kacchan.” Izuku rasps in Katsuki’s ear, licking a long stripe up his neck, nuzzling his ear and biting down on it. Katsuki whines and obeys, wrapping slick fingers around his dick and stroking it in time with Izuku’s thrusts. Izuku bends Katsuki’s body further, nips and mouths at his neck, careful to not leave any marks behind. His stomach clenches and jumps in heat, so close to climaxing already.
Katsuki’s thighs shake and his hole spasms around Izuku’s cock sporadically and Izuku knows he’s about to cum. He covers Katsuki’s dick with his hand, rubbing the head against his slippery palm while he grinds away at Katsuki’s prostate. The added stimulation of Izuku’s palm is enough to hurtle him towards the edge, his dick tingling and stomach clenching as he cums with a broken moan and a string of profanities that would make a whole convent of nuns blush.
Izuku catches the cum spurting out on his palm so that it doesn’t splatter on their dress clothes, his own hips jerking and faltering in their pace when Katsuki’s hole tightens around him. “Cum inside, Deku. Fill me up.” Katsuki demands, eyes glassy and hazy with desire.
Izuku shudders at that, a growl rumbling low in his throat as slams his cock in once, twice, before he’s cumming with a deep, muffled groan.
“Just like that, baby. Fuck it into me, c’mon,” Katsuki eggs him on, soft and warm hole tightening around Izuku’s cock to milk him. “Kacchan, hnnggh—” Izuku whines. His dick pulses and more semen squirts out, thoroughly coating Katsuki’s insides, hips thrusting shallowly and fucking the cum into his lover till they’re both sore and well into oversensitivity. Once they’re both done, just standing there slumped over each other, catching their breaths, Katsuki brings Izuku’s soiled hand up in front of him.
“Lick,” he says, using the same tone that Izuku used just minutes prior, lips playing a smirk and eyes twinkling.
Cute, little vixen.
Izuku grins, bringing his hand to his lips, tongue snaking out to lick Katsuki’s cum off his fingers and palm. His spent dick gives a twitch at the way Katsuki bites his lower lip, red eyes tracking every movement his tongue makes. Izuku sucks on his fingers, cleaning up everything and not letting a single drop go waste.
After that, they help each other put their clothes back on. Their limbs are uncoordinated and slow after a mind blowing fuck, but they do it eventually. Katsuki doesn’t mind the cum spilling out of his ass as he pulls his slacks back up. The very thought of his cum cooling and drying on Katsuki’s skin and inside his ass makes heat pool low in Izuku’s groin, his dick giving another twitch. He ignores it in favour of tucking Katsuki’s shirt in his pants because as much as he’d like to go for round two, they have a service to attend and a God to pray to, even if it’s just for the sake of their parents.
Katsuki helps Izuku pull his pants up and buttons his shirt, smoothing out the wrinkles as best as he can. Izuku reties the tie around Katsuki’s neck and smiles fondly when his boyfriend combs his unruly green hair with gentle fingers so that it’s not so messy. They share a few kisses, before Katsuki exits the confessional. Izuku watches him go, the slight limp to his steps making his chest preen with pride.
He counts upto five seconds before slipping out of the booth, glancing up at the statue of their saviour looking down at him. He winks at it, grinning as he walks towards the hall and takes a seat beside his mother. Inko gives his arm a gentle squeeze and smiles at him before returning her attention to the priest. As the hymns start, Izuku falls into routine habitually, singing and saying the memorised prayers.
Izuku and Katsuki. Deku and Kacchan. As it should be and as it will be, now and forevermore,
Amen.
