Work Text:
Blood Riot watches from the shadows as the pretty hero squirms, curses, and tries to jerk himself free, face flushed and sweat dripping down his naked back. All of that beautiful fair skin is on full display where Katsuki is bent over the padded bench, his head and wrists locked securely into the attached stockade with built in quirk suppression bands. His hips are elevated by the bench, ass up in the air and legs spread by the spreader bar locked around his ankles. Riot does quick calculations to make sure that he got the height perfectly right for what he has in mind, and a pleased smile stretches his lips. Katsuki Bakugou, the pro hero Dynamight, is right where he wants him.
It had taken the hero quite a while to wake up, giving Riot just enough time to strip him bare and maneuver him into position, before giddily locking each limb in place, preventing the hero from escaping or moving much at all. Riot’s thick cock is already twitching and laying heavily between his legs as he stalks towards his prey from behind, eyes fixated on Katsuki’s exposed asshole that is currently adorned with a lovely red jewel that matches his eyes. Riot had done Katsuki the favor while he was out and stretched that tight little hole open and worked the thick plug into his plushy insides.
Katsuki must hear his footsteps, because he tries to turn to look over his shoulder but the stockade prevents him from turning his neck. “Goddamnit! I know it’s you, Riot! Let me the fuck out of here!” Katsuki screams in rage, his limbs trembling a little with the wrathful emotion that seems to be constantly on tap within the small blonde. A low chuckle rumbles from Riot’s chest as he sets the items in his hand down on the tray he has set up right next to the bench splaying Katsuki open. He lays the items out one at a time before turning to his restrained captive. Reaching out, he runs his palm up Katsuki’s flank and pats him lightly on the ass like one would do to a prize pony.
Katsuki jerks under the touch. “When I get out of here, I’m going to fucking kill you,” Katsuki grits out through clenched teeth.
“ IF you get out of here,” Riot corrects lightly. “You’re right where I want you to be, pretty hero,” he coos.
If possible, Katsuki’s skin turns even more red. Riot can’t be sure if it’s a blush of embarrassment, or if it’s from the rage boiling under Katsuki’s skin…either way Riot admires the effect he’s having on the blonde.
“I fucking hate you! What even is this?!” Katsuki shouts, voice stilted like he’s trying to keep up a brave face. Riot understands…all heroes have their reputations to uphold after all.
Riot grabs Katsuki’s ass cheeks in a firm grip and spreads them further apart, not bothering to respond. Katsuki begins to tremble in his hold. Without saying a word, he releases one of Katsuki’s cheeks and reaches down between his legs to grab roughly at the cock dangling there. Katsuki jolts.
“What the fuck?! Don’t fucking touch me!” Katsuki hisses like a feral cat.
Riot smirks when Katsuki’s shaft is swollen and hard. He thumbs over the tip to find droplets of precome starting to bead at the tip. Katsuki lets out a grunt when Riot gives him a singular tight stroke, rewarded with more precome dripping from the tip. This is the most attention he plans on giving Katsuki’s cock tonight. It’s merely a visual aid to help him gauge Katsuki’s arousal. The blonde will actively deny his reactions, but his body…his body will tell Riot the truth. He drops Katsuki’s cock unceremoniously, leaving it to hang uselessly dripping to the floor below.
“You can’t lie to me, hero. Your slutty little body is giving you away. You fucking want this,” Riot comments nonchalantly.
Katsuki practically snarls and starts yanking against the restraints with more vigor. Riot knows that it’s a fruitless endeavor. He designed and built this system himself. “You might want to save your strength, baby. You’re going to need it,” he purrs.
“FUCK YOU! LET ME THE FUCK OUT OF HERE!”
Riot clucks his tongue, hauls his hand back and slaps Katsuki’s ass cheek with a loud smack. The hero cries out with the impact. A lovely red mark in the shape of Riot’s hand begins to form, contrasting nicely with Katsuki’s pale skin. “You really should be nicer to me, Katsuki,” Riot warns in a light voice and taps against the gem protruding from Katsuki’s entrance. Katsuki stills like prey caught in a trap. “The way I see it, you have two options. You can be my good boy and I’ll treat you so nice, baby. Or you can be my naughty boy, and I’ll punish you until you’re begging me to stop. It’s your choice, hero.”
“Go fuck yourself, Riot,” Katsuki whispers fiercely.
Riot’s answering grin is wide and mean. Katsuki never disappoints. Riot grabs two items from the table and makes his way towards Katsuki’s head. When he stands just in front of him, Katsuki glares up at him defiantly, meeting Riot’s eyes with pure vitriol written in his expression.
“Open your mouth, baby,” Riot commands coldly.
“Like fucking hell–” Katsuki starts and Riot takes advantage of his tirade by hardening his fingers and gripping the hinges of Katsuki’s jaw, making the lower half drop automatically to alleviate the pain. Riot shoves the silicone ball past Katsuki’s teeth and secures the strap behind his head quickly. Katsuki’s shouting continues, muffled through the gag as he tries to shake his head from side to side in a futile attempt to remove it from his mouth. Riot just smiles at him and winks before slipping the blindfold over Katsuki’s head to cover his eyes.
Katsuki falls silent and his body tenses, suddenly deprived of two of his senses. Riot pets through Katsuki’s hair in a soothing gesture. Really it was the hero’s fault for not heeding Riot’s warning. He was given a choice…and he chose punishment. That’s okay though, Riot knows just what to do with naughty boys. His fingers retreat from Katsuki’s soft strands as he walks back to the rear of the hero.
Riot looks down and notices the little puddle starting to accumulate on the floor beneath Katsuki, where his dick is still hard and leaking. Time to get started… Without ceremony, Riot reaches out and tugs the plug from Katsuki’s ass with a harsh yank making Katsuki jump and a muffled yelp can be heard through the gag. Riot sets the plug to the side and pulls one of Katsuki’s cheeks to the side to inspect his hole. He prods his finger along the outer edge of the pulsing rim, testing the give. Katsuki’s hole quickly shrinks down, despite being softened by the medium sized plug he’d inserted earlier. His little hero had been so fucking tight while Riot had slowly and methodically stretched his hole just large enough to take it.
The little entrance winks enticingly at Riot as he reaches once again towards his makeshift workstation and pumps several squirts of lube over his fingers. Katsuki is squirming again, legs shaking and Riot likes to think that it’s anticipation getting him worked up. Not wanting to keep his hero waiting, Riot pushes three fingers through his resistance and twists them inside of sucking heat to add more lube to the tight channel. He doesn’t spend too long on it though, just enough to slick Katsuki’s walls before pulling them out again. He wipes his hands on a nearby towel and grabs the thicker plug from his tray. He turns the vibration on low and presses it to the outside of Katsuki’s rim, letting him feel the vibrations against his sensitive pucker.
“Feel that, baby? It’s gonna feel so good inside you. You can scream and moan all you want, but nobody is going to hear you,” Riot threatens darkly and begins to push the pulsing plug inside, forcing Katsuki’s hole to stretch wider than it had previously. Katsuki groans through the gag and tries to wiggle his hips to no avail. “I know you can’t see it, but your slutty little fuckhole is practically begging for it.” He applies a little more pressure when Katsuki’s rim resists the width of the bulge, but then it suddenly disappears inside and Katsuki’s rim sinks down over the flared base, muffling the sound of the vibration. Riot taps against the base to turn the vibration up and Katsuki moans around the gag while his cock twitches.
Riot pets over his cheeks and massages his lower back. “Fuck, little hero…you look so good spread open and restrained. I even love your mouth. Makes me so fucking hard when you’re spitting mad and shouting. Just makes me want to stuff my cock down your throat.”
A blush spreads down Katsuki’s shoulders and Riot can even see it at the tips of the hero’s ears. “You’d like that, wouldn’t you? I know your secret, Dynamight. You’re just a slutty little bottom that needs his holes bred and filled with cum.”
A tap on the bottom of the plug increases the vibration so that steady buzzing can be heard throughout the room. Katsuki’s chin tilts down in the stockade and he breathes heavily through his nose. Riot grabs two earplugs from the table and walks to stand in front of him, smiling smugly at the drool dripping down the hero’s chin from around the ball gag. Leaning down close to the hero’s ear, Riot nuzzles lightly against his cheek. “Look at you, so helpless and needy. I bet you needed this so badly. Don’t worry, little hero…I’m here to make you take it. By the time I’m done with you, you’re gonna be a fucked out mess addicted to my cock. Gonna make you cum so many times that you think you’re gonna lose your mind. And when you’re begging and pleading for it all to stop…I won’t be able to hear you because you just had to go and provoke me,” Riot whispers harshly.
He strokes through Katsuki’s hair and grabs the hair at his crown in a tight fist before yanking the hero’s head up as far as the stockade will allow. He pops one of the earplugs into Katsuki’s opposite ear and then leans in close again. “I’m gonna give you one chance, little slut. Here’s how this is gonna go…You’re gonna sit and think about your actions for as long as I deem appropriate. If you can be my good boy and NOT cum during that time, your punishment will be over. If not…well…I can get really creative.” Eijirou shoves the second earplug in Katsuki’s ear, drops his head, and walks back to his position next to Katsuki’s upturned ass. He grabs the base of the plug and pulls it slowly past Katsuki’s rim, making it gape wide around the bulge and then shoves it back in. Katsuki whimpers through the gag. Riot taps the plug twice, doubling the vibration. Instantly, his little hero starts to wriggle and squirm. The plug Riot had chosen is specifically designed to press firmly against the prostate. It will be nothing short of a miracle if Katsuki doesn’t cum, and even if he doesn’t, Riot will keep going until he does. There’s no shot of the hero winning this, but Katsuki doesn’t need to know that. All Riot wants him focused on is on the feeling of his body being used and his lack of control.
There’s a padded rolling chair next to the workstation and Riot makes himself comfortable after glancing at the clock. He laces his hands behind his head, eyes glued to Katsuki’s sweaty twitching muscles as he tries desperately to be a good boy. Jokes on him though, Riot doesn’t want him to be a good boy. He wants Katsuki to be a desperate little fuckhole, begging for Riot’s cock and cum. He wants to take his pristine hero and turn him into a sloppy defiled mess.
Riot’s cock is heavy and so fucking hard that it almost hurts. Every time Katsuki moans and mewls into the gag, it jerks against Riot’s thick muscled thigh. When the fifteen minute mark passes, Riot is forced to take himself in hand and stroke over the shaft to try and ease the pressure. All he can think about is shoving his cock into Katsuki’s tight wet heat. His imagination runs wild with all of the possibilities now that he has the hero at his mercy. At the rate this is going, his little fuckhole is going to be raw and dripping with cum with how many loads Riot plans to fill him with.
Originally, he was planning to let the hero go after this, but looking at Katsuki’s straining body and listening to his slutty sounds, Riot is plotting a different outcome where he keeps Katsuki chained to his bed, spread open and ready to be used any time Riot wants. He could be Riot’s little cumdump, filled constantly with cum and plugged to keep it all warm inside. He would open his mouth willingly and let Riot fuck his throat and feed his belly with so much cum that he bloats, then afterward he would keep Riot’s cock warm in the cavern of that profane mouth.
Fuck… At the thirty minute mark, he stands and checks on the blonde. Katsuki’s whole body is shivering and while there’s a pool of precome beneath his drooling cock, he still hasn’t cum. Time to up the stakes. Riot gives a sharp tug to the plug and Katsuki lets out a surprised yelp through the gag. Pulling harshly on the plug, he works it roughly inside Katsuki, never fully pulling it out. Katsuki moans freely, clearly enjoying the sensation. Just to mix it up, Riot releases the plug, letting it sink back in to the base, clicks the button to level up the vibration and walks to Katsuki’s head. The hero flinches when one of his earplugs is removed.
“Doing so well, baby. Looks like you might just be my good boy yet,” Riot praises softly. He knows Katsuki’s ears will be sensitive after being silenced for lengthy periods of time. “But your punishment isn’t done yet. I know you like a good challenge. Let me see how ‘Plus Ultra’ you can be…” Riot puts the plug back in place and makes his way back to his chair and plops back down to give himself a couple more idle strokes. He briefly entertains the idea of jerking himself off, just to take the pressure off for enough time to truly break Katsuki in, but then he chastises himself for being impatient. No…he’s saving his cum just for his little hero.
After another fifteen minutes, Katsuki has gone limp in the restraints and lets out a steady stream of groans and whines, hips twitching with aborted movements. His little hero has already lasted longer than Riot expected. That won’t do at all… He stands and taps the plug twice. Katsuki lets out a scream and begins quaking again. Riot taps the plug again. The buzz is loud enough that the whole room sounds like a nest of angry buzzing bees. Katsuki’s legs tense and his back arches against the bench. SMACK! Riot lands the blow right over his mark from before, and Katsuki jolts and screeches. SMACK! He lands a blow on the opposite cheek. From there, he alternates cheeks until both globes are reddened and Katsuki’s cries have turned to outright wailing. He jiggles the plug in Katsuki’s ass, working it up and down and then side to side. He tugs it out with a wet squelch and then plunges it back in a couple of times.
He’s not sure if Katsuki has ever had an untouched orgasm, but Riot is determined to train his little hole into cumming just from sticking his cock in. “C’mon, my little cockwhore, cum for me,” Eijriou mutters before pulling the plug out fully. He squirts more lube on the the intensely vibrating toy and turns back, noting that Katsuki’s hole now gapes a little from the plug’s thickness. In a last ditch effort, he turns the plug up all the way and drives it into that hungry hole and grinds it deep inside. Katsuki lets out a full bodied scream and Riot smiles hearing the satisfying sound of cum splashing to the floor below, he leans back to watch as Katsuki’s dick practically flops as it unloads thick white spunk in a flood from his slit.
Satisfied, Riot reaches up and turns the plug off and pats against Katsuki’s ass in a condescending manner. He doesn’t remove the plug, wanting to keep Katsuki nice and open for what comes next.
Riot runs light fingers over Katsuki’s still spasming muscles as he stalks forward until he’s facing Katsuki. He leans down and kisses Katsuki’s sweaty forehead and delights in the tear tracks running from under the blindfold. Drool runs freely around the gag and Katsuki is surprisingly quiet. Gently, Riot removes one of the earplugs and cups Katsuki’s chin. “Looks like you can’t be good after all. You were supposed to hold it, little slut. Guess you just need some more training.”
Katsuki mumbles something that Riot can’t make out around the gag. He reaches behind Katsuki’s head to loosen the straps just enough that the ball can pop out from behind clenched teeth and rest against the divot in Katsuki’s chin.
“What was that, little hero? You were talking with your mouth full…” Riot says chidingly.
“You fucking wanted me to fail…” Katsuki accuses, voice scratchy and raw.
Riot smirks, “Of course, little slut. I never stipulated how you would be punished or for how long.”
“Fucking villains,” Katsuki mutters peevishly and shivers a little when an aftershock tumbles through his body.
“That’s right… and right now, I own you, Katsuki. You’re my little plaything. My little pet hero…that I’m going to punish until he’s the perfect little cumslut for me,” Riot sneers. He pinches Katsuki’s jaw again and forces the ball back between his teeth before tightening the strap once again. “Until you learn some respect, my little pet isn’t allowed to talk.”
Katsuki makes a growling sound in the back of his throat. Still so stubborn… Riot fucking loves it. He pulls the other earplug out and carries them back to the table. He wants Katsuki to hear every filthy degrading thing that Riot wants to call him, wants him to learn to appreciate and soak up praise like a sponge, wants him to hear Riot’s commands and get off on his words alone.
Riot eyes his table again and begins to lube a long and ribbed dildo that is just slightly smaller than his own cock. He needs to stretch Katsuki a little more to be able to fit his monster cock (perk of his quirk), but also wants Katsuki to still feel the stretch when Riot finally stuffs himself inside. Riot gives his cock a couple of pulls with the excess lube on his hand before turning to Katsuki and pulling the plug from his quivering hole. Katsuki’s gapes, pink and fleshy insides on display as Riot aims the dildo and slowly presses it in. He watches each ridge of the silicone catch lightly on Katsuki’s rim as he pushes. Katsuki groans with each inserted inch. “You feel that, little fuckhole? This is just the warm-up. I should make you thank me for going through all of this trouble to make sure this little hole doesn’t split apart on my cock.”
When it reaches the hilt, Riot draws it back out and drives it back in sharply just to hear Katsuki cry out. It appears the little hero is just as vocal in bed as he is out on the streets. He imagines that Katsuki is still ringing with oversensitivity, but now that he’s cum from just his little gland, the next one should be easier. Riot sets a steady rhythm to the the sounds of Katsuki’s panting desperate breaths, making sure to angle the toy until Katsuki’s hips jolt. There it is… Keeping his pace, Riot leans down and checks on Katsuki’s cock which is already starting to fill out again at the stimulation.
“I’ve been thinking…” Riot muses out loud. “Maybe I should just keep you like this all the time. Just a pretty little cocksleeve for me to enjoy. Your little hole was made to be bred, baby. Feel how it just swallows up anything I shove inside? It’s so fucking greedy. Maybe I should just open that door and let my whole crew have a go. I’m a generous guy, Dynamight… I could fill that hole with a never ending supply of cock and cum. Not that I like the idea of sharing my toy, but if that’s what my pet needs, I’m more than happy to supply. Or maybe I should just set up a fucking machine to drill this sweet little cumhole constantly…day and fucking night. Of course, you’d get breaks so that I could fill that little belly with cum and then let the machine pound it deeper inside you. Doesn’t that sound nice?”
Katsuki lets out a pornographic squeal when Riot picks up the pace and batters the toy against his prostate. It almost makes him wish Katsuki wasn’t gagged so he could hear it without interference. “How does it feel knowing that a villain is fucking you open? I should set a camera up so that the whole world can see how fucking desperate you are for my cock…” Katsuki starts writhing against the restraints, making the table wobble and Riot can tell that he’s getting close. “Show me how a good hero cums, Katsuki. Let it all go so I can give you what you really want. Cum for me, little cockslut,” Riot commands.
As if by words alone, Katsuki goes tense and his breaths become near frantic. Riot keeps pounding the toy inside him, even as he can see Katsuki’s hole visibly clench tightly around the toy. The sound of liquid splashing to the floor is music to Riot’s ears. He keeps working the toy, making Katsuki shriek and try to pull away, but Riot wants every drop of cum milked from his balls. When there’s no longer the sound of dripping spurts, Riot slowly pulls the toy out and marvels as Katsuki’s rim flutters and struggles to close. He sets the toy to the side and walks to the front again. Riot’s cock is painfully swaying between his legs, weighted and swollen with his arousal. Fisting Katsuki’s hair, he yanks his head upwards again, making Katsuki’s nose flare with a sharp exhale. With his other hand, he lifts the blindfold from Katsuki’s eyes. Watery red gemstones blink up at him in the dim light, pupils dilated and expression completely fucked out. “Such a pretty hero,” Riot murmurs and strokes Katsuki’s cheek. Riot then jerks Katsuki by the hair and shoves his face next to his heavy cock until Katsuki’s nose brushes his heavy engorged balls. He uses his hold to rub Katsuki’s face back and forth over the top of his shaft and intermittently shoves his face deeper so that he’s forced to inhale Riot’s musk. Riot leaks to the floor below while showing the hero his place, worshiping his cock and balls. He wishes he could feel Katsuki’s mouth and tongue slobbering and sucking on them, but that will take more time to train. Soon though…
“This is where you belong, Katsuki,” Riot confides, like he’s telling some great secret. “You were never meant to be a hero…you were meant for this…meant to be on your knees for me. Meant to be stuffed full of villain cock.” He pulls Katsuki’s face back and grabs his cock with his other hand. He guides his slick cock tip to Katsuki’s lips stretched around the gag and smears the thick liquid over them. Katsuki’s eyes cross while he tries to watch Riot’s cock. His face flashes with uncertainty and trepidation, making Riot chuckle.
He waves his cock teasingly in front of Katsuki’s face, like waving a treat in front of an excited dog. “Are you imagining this inside you, little cockwhore? You want it so fucking bad you can taste it, isn’t that right?” Katsuki tries to shake his head no.
“No? Well that’s too bad, because it’s going inside you anyway. I’m gonna cram it all inside until you fucking burst. Then I’m going to breed that fucking hole until you pass out,” Riot snarls.
He taps his cock against Katsuki’s cheek, smearing more of his seed over his face. “Hmmm…maybe I’ll save one of my loads to cum all over this pretty face. Maybe then it will sink in who you belong to.” With that, Riot releases Katsuki’s hair and strides back to his table where he pumps an absurd amount of lube over his cock. He feels like he could cum just from the feel of the cool liquid spread over his shaft. As an afterthought, he grabs the metal custom cockring and snaps it over the base of his length before he turns back to Katsuki.
He presses his tip to Katsuki’s still gaping hole and grabs both of Katsuki’s hips in a bruising hold. Katsuki’s insides are slick and velvet soft as he begins to push inside. Even after all of the prep, Katsuki is still tight.
Katsuki is squirming and grunting while Riot feeds his cock into his silky channel. “Fuck, baby, this hole was fucking made for me.” When Riot is halfway in, he pauses and smirks…lulling Katsuki into a false sense of security. When the muscles in Katsuki’s back finally untense and his hole loosens just a fraction, Riot plunges the rest of the way in, earning him another one of those delectable squeals. He pulls back to the tip and starts the process all over again, slowly coaxing Katsuki’s tunnel to adjust and relax.
Katsuki is muttering incoherently around the gag and Riot laughs, wondering if he’s finally broken the young hero. “There we go,” Riot rambles. “Just give in and accept it. All you are is a hole for my cock to fuck into, my little breeding bitch.”
Katsuki lets out a groan and Riot feels a hard clench against his cock that makes him smirk knowingly. His little hero is getting off on this . “I know you like it, Katsuki. You like being mine. With this firm little ass, lithe sexy body, and beautiful blood red eyes…You’re just begging for it like a slut. Everybody wants a fucking piece, but they’re too late because you belong impaled on my fucking cock, and my cock only.”
Katsuki clenches down again, muscles constricting around Riot. Riot rewards him by rocking his cock in and out harder. He wonders if Katsuki’s belly would bulge from how deep Riot is inside him. Determined to test the theory, he leans over Katsuki and wiggles one of his hands between Katsuki’s belly and the padding of the bench to press against the hero’s navel. Driving into the hilt, Riot feels the skin of Katsuki’s flat belly push outwards. Riot rubs upwards hard against the spot and suddenly Katsuki tenses and lets out an animalistic sound that Riot isn’t sure how to classify, but it makes his cock pulse. Then, he feels splatters of liquid hit his bare feet as Katsuki’s hole flutters around his cock, and he grins. “Awwww did my little slut just cum from me pressing on your little belly bulge?” he mocks. “Such a good little pet, finally learning…”
Katsuki whines and is practically hyperventilating as Riot’s hips slap against his ass, filling the air with lewd smacking sounds. Snug walls cling to Riot’s cock as he continues to drag within them. Suddenly, Katsuki starts rapid fire yelling through the gag and Riot can just barely see over the stockade as he shakes his head from side to side. Riot can just imagine that he’s begging and pleading for a break, but Riot isn’t going to give him one. “I warned you I was gonna keep fucking you until you pass out. Gonna fucking cream this hole,” Riot growls and his thrusts slow when Katsuki’s clamps down over his cock and convulses in his bindings. Riot doesn’t feel or hear Katsuki’s cock unload, but the signs of orgasm are evident. “That’s it, keep cumming on my fucking cock,” he coaches with a clenched jaw and slams his hips forward, bullying his cock through constricting muscles.
Katsuki goes limp after a few moments and Riot pauses only for a second to pull out and unsnap the cock ring before plunging back in and resuming right where he left off…brutally fucking his little captive hero. He’s getting fucking close, having edged himself so long. Meanwhile, his captive has gone completely lax beneath him, only letting out soft puffs of air and little grunts with each thrust. Riot’s orgasm crests over him like a tidal wave and he grabs onto Katsuki as his legs threaten to buckle under the force of pressure in his balls as a flood of heat pours from his cock, straight into Katsuki’s welcoming insides. Spurt after spurt of Riot’s thick cum pumps inside of Katsuki as he continues to thrust, trying to work it deeper.
A low whimper catches his attention. Still awake then… Riot slowly pulls his cock out and watches as Katsuki’s hole gapes wide and a thin trickle of white begins to drip down his taint. Riot quickly grabs the vibrating plug, slathers it with lube and works into Katsuki’s loose wet hole. He turns the vibration on low and smirks when Katsuki barely twitches as the stimulation. Riot reaches between Katsuki’s legs and grabs a limp cock, verifying that his hero did cum again. He wonders if it was a dry orgasm.
Legs feeling like jello, Riot walks around to face Katsuki. Red eyes are distant and hazy, unfocused on anything in particular as Riot unstraps the gag and gently pulls the ball from between the hero’s teeth. With firm fingers Riot massages either side of Katsuki’s jaw. The blonde is uncharacteristically silent, but leans into Riot’s touches easily. “Good boy,” Riot praises softly and watches as Katsuki’s eyes flutter briefly. His little hero is floating… Riot’s cock gives a jerk and begins to fill again.
“Sweet little slut…” he coos and Katsuki looks up at him, soft and fucked out.
Riot carefully lowers his hold from Katsuki and his hero’s chin dips down to rest against the padding of the stockade. His cock is already plump when he reaches down and pumps it in his fist as he looks down at the ruined hero.
“Who do you belong to, little slut?” Riot asks, dropping his voice down low.
Katsuki’s head doesn’t lift, but Riot can make out his raspy response. “You.”
“That’s right, baby,” Riot confirms and strokes his length harder. “And who is my little slutty fuckhole?”
“Me,” Katsuki breathes out.
Riot grins and walks back to his station to slick his cock. “Gonna fuck another load into you,” Riot warns while pulling the buzzing plug out and thrusts back into Katsuki’s sloppy hole, sheathing himself completely. Katsuki whimpers again… God, that sound . There’s no place that Riot would rather be than fucking his little hero over and over again. He should have taken Katsuki sooner. He wasn’t lying when he said that Katsuki was meant for this. His plush walls suck on Riot’s cock as he slowly rocks his hips.
“Riot, please…” Katsuki rasps out. “Please don’t stop.” His voice cuts out, coming out as a croak.
“You’ll take what I give you, slut,” Riot huffs out, pleased with Katsuki’s begging.
Katsuki moans at the words and Riot can’t help but think that Katsuki in subspace is the most erotic thing he’s ever experienced.
“Riot…” Katsuki slurs when Riot thrusts in harder.
Katsuki saying his name like that will forever live rent-free in Riot’s brain. He leans back just a little bit to watch his thick girth slide in and out of Katsuki’s puffy and swollen rim. The sight nearly undoes him right there. He reaches over, not pulling out and grabs his phone from the workstation. He pulls up the video app and hits record, aiming the camera downward to capture the image of his slick cock splitting Katsuki open.
“Riot p-please…” Katsuki stammers and Riot redirects the camera to capture all of Katsuki’s pale skin, trapped below him. Katsuki clenches down as Riot speeds up.
“Is my little cocksleeve gonna cum again?” Riot asks loud enough for the recording to pick up.
“Yesssss,” Katsuki hisses and starts to tense and arch as the pressure builds.
Riot starts fucking into him harshly as his balls also begin to grow tight. “You can hold it, little slut. Don’t you dare cum before me,” he commands, while aiming his camera back down as he rails his cock inside.
“I can’t hold it,” Katsuki cries out brokenly.
“Yes, you fucking can. Good boys hold their cum until they’re told,” Riot sneers and pumps his hips faster, trying to hold the camera steady, but it's proving to be impossible. “Beg for it, little slut. You wanna cum so bad, convince me!”
Katsuki groans long and loud. “Please, Riot. Please let me cum. Please stuff me with your cum, breed my slutty little hole. Anything! Just please!” he pleads, a frantic edge to his voice.
Balls tingling, Riot shoves in deep and fucks with short harsh strokes that rattle the bench. He’s forced to toss the phone to the side as his nails dig into fair skin. “Cum for me, slut!”
Katsuki howls, voice shredded and barely there, jerking in the restraints.
Riot snarls just as his vision whites out and clenches on for dear life when this orgasm rolls over him more powerfully than the first. His cock jerks and throbs, as liquid heat shoots from his slit to add to the growing pool in Katsuki’s belly. Katsuki’s hole dutifully milks him through it until his head swims from lack of blood flow. “Fuck, so good,” he mutters almost to himself, grabbing the plug and gingerly extracting his softening cock. Before any cum can escape, he plugs Katsuki up.
His slutty hero is silent and limp over the bench as Riot makes his way around. Katsuki’s head is tilted downward, eyes closed, and wheezing out harsh breaths. His face is completely relaxed in a way that Riot has never seen before. “Katsuki?” he calls softly.
“Hmmm…”
“Baby, are you okay?” He asks gently.
Katsuki just hums in his crackled voice.
Riot leans to the side and unlatches the stockade, shifting it upward and to the side, freeing Katsuki’s upper body. The spreader bar comes off next as Riot quickly and efficiently releases all of the restraints. He carefully rolls a limp and passed out Katsuki into his arms and makes for the bed in the corner of the room. There’s already a warm washcloth in a bowl waiting on the nightstand when he lays Katsuki down and begins to wipe down sweat and cum covered skin. He leaves the plug in, knowing that Katsuki doesn’t like to be empty after a scene. Crawling in next to his little hero, he pulls Katsuki into his side and nuzzles down into his hair.
He lays there for quite some time, just listening to Katsuki’s soft breaths and holding him close.
“I can hear your sappy thoughts from here,” Katsuki snarks suddenly, breaking the silence, making Riot jump.
“How did you know they were sappy?” Riot asks playfully and kisses Katsuki’s temple.
“Cuz you’re always sappy after a scene,” Katsuki deadpans.
Riot chuckles, “And what’s wrong with that?”
Katsuki shrugs a shoulder and smirks, “Nothin’.”
“We both know that the big bad Dynamight likes kinky sex and cuddles after a big villain bust,” Riot jokes. “As long as it’s not my ass you’re busting, I’m more than happy to oblige.”
Katsuki snickers. “Nah, don’t gotta bust you. Just gotta make a booty call and you come running. Instant distraction. Can’t be out destroying society if you’re here destroying my ass…”
Riot laughs bright and loud, while Katsuki just snuggles closer. “You’ve got a point, pretty hero.”
After his laughter settles, Riot strokes down Katsuki’s arm. “I didn’t go too hard, did I?”
Katsuki peeks an eye open and glances up, “Your quirk is literally hardening…” he says seriously and then snorts, unable to keep his composure.
“Always gotta be a brat, don’t you?” Riot raises an eyebrow.
Katsuki hums in agreement. “That might have been the best sex of my life. Fuck, I’m gonna be feeling it for days.”
Riot shifts and lays over Katsuki, pinning his arms above his head… “Who says you’re done, pretty hero? Pretty sure that when we agreed to this, I said I was gonna fuck you senseless…and I don’t think you’re quite there just yet.”
