Riot pulls his knees upwards before spreading them to either side, making sure that his Kitty Kat will have easy access to exactly where Riot wants him. His boy looks fucking delicious standing at the edge of the bed wearing nothing but Riot’s thick red collar around his neck, flushed with arousal and his thighs shiny with wetness. The villain licks his lips and fists his hard and throbbing cock as he eyes Katsuki’s corded body and sleek muscles, eyes catching on the perfect pussy between his legs. Riot has already been inside that pussy once tonight, the residual wetness still coating his cock under his hand. But for now, he wants something different from the hero that is his nearly nightly indulgence. They’ve been seeing each other secretly for over a year now and every time is just as exciting as the first. He side-eyes the toys on the bed, noticing Katsuki’s glance towards them. “Are you curious, Kitty Kat?” he purrs with a smirk.
“Yes sir,” Katsuki responds quietly, already sunk into the submissive space that only Riot gets to see from him. His little hero is gloriously furious, passionate, and shines so fucking brightly outside of these four walls, but in here…he belongs to Riot alone and Riot demands immediate compliance and quiet servitude. He may be a villain, but Katsuki’s trust in him is almost humbling, an honor of the highest order from the explosive hero. In this room, Katsuki gives Riot the greatest gift, the gift of control and in exchange, Katsuki gets to give it up and feel the relief from the expectations that weigh heavily over him. His baby often comes to him ragged and run down, but Riot knows just how to polish him back up, loosen up those tense muscles and make that pretty pussy squirt until Katsuki is a melted puddle on the floor.
Riot uses his other hand to crook a finger in his boy’s direction. “Come here, Kitty Kat,” he commands firmly. Immediately, Katsuki crawls onto the bed and pauses as if he’s unsure of where he’s supposed to go. “Right up here, baby,” Riot coaxes and points to the spot just below his exposed ass. Katsuki shuffles forward and a pleased thrum shoots through Riot to see hunger written in ruby eyes. “Good, now open your mouth,” Riot growls in a low tone and watches a shiver roll through his boy as he drops his jaw almost eagerly. Riot drops his hand down between his legs while still pumping his cock slowly with the other one. Katsuki’s eyes drop to where Riot pets over his hole with firm fingertips. Katsuki’s eyes widen momentarily as the implication sets in and Riot watches him carefully for any sign of discomfort. Riot knows that he’s switching up the dynamics tonight, posing the hero with a new challenge, a new way to serve him. They’ve never played this way before, but Riot is hoping that Katsuki will rise to the occasion. He knows that he’s won when he watches one of Katsuki’s hands shift and move towards his pussy in an unconscious motion while he stares at Riot’s fingers like he’s hypnotized.
Riot clicks his tongue in warning and Katsuki’s hand stills and shoots back to its proper resting spot on the top of his thigh. Riot almost slips and grins, but instead he keeps intense eye contact, daring Katsuki to touch himself without permission. He can see the apology poised on the tip of Katsuki’s tongue, but he doesn’t dare utter a word after Riot had commanded him to open his mouth. “Now, bend over…hands and spread knees, Kitty Kat. Wanna see that back arched and ass in the air while you use your tongue…” Riot taps over his hole, drawing Katsuki’s gaze back down. “You’re gonna use that sexy mouth of yours, right here, Kitty Kat and get it nice and fucking wet for me.”
He’s never seen Katsuki shift so fast as he drops his hands to the mattress and arches his back to spread his knees wide, forcing his ass high into the air. The moment that hot mouth seals over his hole, Riot groans and wraps a fist in Katsuki’s hair to pull him closer just as a wet tongue licks over his twitching pucker. “Fuck yeah, Kitty Kat, lick it just like that,” he praises, fisting his cock a little harder as Katsuki swipes his tongue back and forth over his entrance with eager kitten licks. Riot’s breaths come a little faster when Katsuki switches to swirling his tongue in circles around the rim. Fuck…he’s good at this. Riot tugs his hair a little harder when Katsuki seals his lips and begins to suck. “Good fucking boy,” Riot groans, the sensation over his hole making his legs tremble and his strokes over his cock quicken. He grits his sharp teeth when Katsuki’s tongue wiggles through the softened rim between hard sucks over the entrance. “Fuck yeah, baby, get your tongue in there…get it nice and deep…” Riot snarls as the tip of Katsuki’s tongue tries to twist and bury further inside, lapping against Riot’s walls and making his cock twitch in his palm. He’s forced to slow his fist over his cock, feeling the tension in his balls already starting to build and he doesn’t want this to be over yet as Katsuki presses in further, tasting Riot’s walls and making them clench over the wet appendage. For a few moments all Riot does is tilt his head back against the mattress and huff aroused breaths as his boy stretches his hole and eats his ass like a four course fucking meal.
Katsuki is like every lewd and obscene wet dream come to life as he sucks and slurps over Riot’s hole messily. Riot leans foreward when he can’t take the teasing anymore and yanks his head upwards, smirking wickedly at the fucked out look on his boy’s face. Drool drips from his chin and is smeared across his cheeks while his eyes are nearly crossed, trying to look up at Riot with his mouth still hanging open. “Such a messy eater, Kitty Kat,” Riot coos, voice low and gritty. Riot reluctantly releases his cock to grab the lube from the bed next to him. “Give me those fingers, baby,” he demands and Katsuki’s hand slowly raises as he shifts his balance to his other hand. Riot isn’t careful as he douses Katsuki’s fingers liberally in the thick shiny substance until they drip to Riot’s skin below. When he’s finished, he closes the cap and sets it to the side for later. He hums in thought, his hand hovering over something he’d picked out for his baby. His hand closes over it and he turns back to Katsuki who is still holding his mouth open. Without ceremony, he shoves the ball past Katsuki’s teeth and spit-soaked lips, efficiently buckling the straps behind his head. “Love it when your mouth is full, baby…” Riot purrs and pets through blonde hair softly before gripping the strands and giving them a sharp tug. “Now get your fucking fingers inside me and open me up…”
Riot revels in the hazy look of acceptance in Katsuki’s eyes just before they shoot downward to where Riot’s hole glistens with spit. Riot twitches as Katsuki’s fingers brush over his hole almost reverently when his hair is released, smearing the slick thickly around the rim. “Don’t play with your food, boy…” Riot growls impatiently as Katsuki spends several moments wetting the rim. Ruby eyes glance up at him briefly, their depths molten and sweet as a finger presses in slowly, almost cautiously. Riot is about to coach him further, but his words dry up instantly when the full length of the digit stretches him wide and sinks in up to the knuckle. It’s been a long while since he’s had anything inside of him and he sucks in a breath at the sudden fullness. He doesn’t miss the smug glint that lights up in Katsuki’s eyes at the sound. “Careful, Kitty Kat,” Riot warns heavily and Katsuki’s features contort into concentration as he starts to methodically open Riot one finger at a time.
By the fourth finger, Riot’s thick cock is drooling over his belly, but he doesn’t dare touch it as Katsuki pets heavily over his walls and spreads his fingers against the tight rim. Occasionally, he grazes Riot’s sweet spot, making him groan at the pressure. He can tell that Katsuki is getting needy and worked up, drool dripping around the ball spreading his lips wide. His ass and legs are quivering where they’re still elevated behind him. Riot has no doubt that his boy is dripping streams of arousal down his thighs as he focuses on his task. Riot is also impatient, his cock hard and purposefully neglected.
“Enough,” Riot orders quietly and Katsuki’s hand immediately withdraws, fingers dragging free through his softened rim with a slick sound. Riot lets his legs go and shifts to sit up with them splayed around his boy. He grabs the new custom red harness that he just purchased while Katsuki watches him curiously. “Up on your knees, Kitty Kat, keep them spread wide for me.” Katsuki gives him a questioning look but sits up between Riot’s legs and shuffles closer, his knees spread wide, exposing his pretty pussy. Riot doesn’t hesitate to palm the bare little mound and rub his hand through the gathered slick there. “Mmmm…you’re soaked, Kitty,” he growls and presses two fingers through wet folds to sink them deep and curl them into Katsuki’s fleshy inner wall. Katsuki makes a whimper through the gag and closes his eyes, making Riot smirk and start to pump the digits slowly. He drops the strap-on between them to brace a hand on Katsuki’s hip, pistoning his fingers a little harder. Katsuki’s legs quake. “Did fingering my ass get you all worked up, baby?” Riot demands and when he receives a nod, he smiles warmly, curling his fingers a little harder against Katsuki’s sweet spot.
He spends several moments just listening to his favorite wet sounds that Katsuki’s pussy makes and his panting breaths before leaning in close and grabbing the back of Katsuki’s neck to pull him forwards so that Riot can breathe directly against his ear. He shoves a third thick finger in next to the other two and Katsuki jerks with a moan through the gag. “Here’s how this is going to go, Kitty Kat,” Riot murmurs against the shell of his ear. “This pussy is fucking mine and it’s going to squirt on my fucking fingers. Then, I’m gonna shove something nice and thick in that cunt, strap it over these lovely hips so that it traps it inside you and stuffs you just right while a little vibrator sits right over your little clit. I’m gonna click a little button on the bottom that’s gonna make your fucking insides buzz and feel so fucking good as it tortures that needy sweet spot. Your gonna lay on your back and cum over and fucking over again for me while I ride moster cock attached to you until my fucking ass gapes and I cum all over you.”
When he pulls back, Katsuki’s eyes are wide and pleading. If his mouth were free, he’d be begging for it. More wetness coats Riot’s fingers as he grips tighter to his boy’s waist and begins to drill them inside mercilessly in just the way that he knows his Kitty Kat likes. Katsuki’s hands fly to grip Riot’s arm, dull nails digging into the skin as he cries out, gritting his teeth over the silicone ball and closing his eyes.
He loves Katsuki like this…helpless to the pleasure he provides. It’s his favorite sight and his cock pulses between his legs, nearly painful in his arousal. He dutifully ignores it, used to edging himself when it comes to his boy. He enjoys the build up of watching Katsuki fall apart until he’s an overstimulated mess of his own fluids and floating high in the afterglow. Riot’s knuckles beat over Katsuki’s pussy lips as he finger-fucks Katsuki hard and fast, making Katsuki practically vibrate over his knees as he mewls. Riot can practically taste his coming release. “C’mon, Kitty Kat…fucking cum for me. Soak the sheets so I can ride that large cock of yours.”
As if he said the magic words, Katsuki thrashes over his hand, bucking his hips down over Riot’s fingers while his pussy flutters wildly and warm cum begins to spray from his cunt like a fountain. “Good fucking boy,” Riot snarls, continuing to thrust through clenching tight walls until the spray tapers to a stop and Katsuki is quaking. He pulls his soaked hand away and his boy shivers at the sudden emptiness, eyes half lidded and chin dripping to the comforter below.
Riot grabs the strap between them by the base of the thick dildo at the bottom and poises the tip at Katsuki’s entrance. When he roughly shoves it in, Katsuki yelps at the sudden stretch. It’s not quite as big as Riot’s cock, but he’d made sure that it was damn close, curved just right to press hard against Katsuki's g-spot. For a moment he fucks it in and out of Katsuki’s slushy hole, enjoying the breathless moans as Katsuki still spasms in aftershocks and sensitivity. Eventually he shoves it in until it’s nice and deep, flush to Katsuki’s lips and holds it in place as he positions the straps and tightens them down. Then he tucks his fingers into the lining and pushes the little switch to turn on the vibrator sewn into the inside. Katsuki jolts with a squeal when it turns on from where it’s pinned directly over his swollen nub. The thick red silicone cock attached to the front bobs with Riot’s adjustments as he tightens the straps just a little more to make sure that the toy is absolutely secure. He plans to fuck himself silly on that thick cock while Katsuki squirms and cries. He licks his lips as he reaches between Katsuki’s legs just below the external dildo and presses the button to make the internal cock vibrate. Katsuki’s groan is animalistic and already his legs start to quiver from where they’d calmed down.
“Does it feel good, baby?” Riot teases in a low voice, smirking when Katsuski nods. Riot presses the button again to increase the vibration and his boy’s teeth clamp over the ball. It’s still not quite enough and Riot presses the button once more. Katsuki curls over, nearly collapsing at the intense stimulation and Riot grins. Perfect . He puts his palm to Katsuki’s chest and roughly shoves him backwards onto the bed, making his Kitty yelp in surprise as he bounces over the mattress. Riot yanks his legs out from underneath him, laying him completely flat until that monstrous red cock sticks straight up from over Katsuki’s tortured pussy. Katsuki’s hands fly up to grip the comforter above his head, eyes fluttering and squirming as Riot grabs the lube and heavily coats the massive red cock until it practically shines and the thick substance slowly drips down over the base to the harness below. He crawls over his prey, hungry for the obscene image Katsuki makes.
Katsuki’s hips helplessly buck over the mattress while the loud buzzing adds a sort of electric tension to the air. Riot leans down and sinks his face into the sweaty skin of Katsuki’s neck and gives a sharp nip to the muscle, just below his leather collar and over his pre-existing marks that he’d sucked into Katsuki’s skin earlier in the night. He’d made sure that they were blooming dark and noticeable above the neckline of Katsuki’s hero costume, possessive in letting the world know that Katsuki was already owned. He and his boy aren’t official in any way…not yet at least, but Riot knows that Katsuki is HIS regardless. Riot has bloodied his hands more than once with anyone that has dared to go after or hurt his hero…Not that Katsuki knows that of course…but Riot has no qualms with defending his territory with violent and ruthless means. Many in the underground are fully aware that Dynamight is off fucking limits and those that don’t will soon learn.
Katsuki trembles below him, body slicked with sweat as he holds on for dear life and pants wildly through his nose while Riot grabs the shaft of the dildo and guides it to his prepared hole and starts to sink down. His Kitty Kat is squirming so much that the tip immediately slips free. He gives another harsh bite to Katsuki’s skin, making him yelp. “Hold still, boy,” he commands through gritted teeth. He can tell that it’s a struggle, but Katsuki tenses and goes still beneath him, almost rigid in his attempt. Riot groans as he once more fits the cock head to his hole and slowly drops over it, enjoying the stretch as it fills his walls. He’d forgotten how good this feels and resolves that from now on, the strap will be a regular feature in their play. He might even have Katsuki work his hole over with a few of the large vibrators and dildos he has in his collection one of these days. Fuck, just the thought has his cock bobbing as half of the length disappears up his ass.
Katsuki is shaking with his eyes tightly closed as if he’s barely holding on, fists nearly white as they grip the bedding. Riot can’t resist and wraps a hand around his throat in a possessive manner, squeezing lightly at the sides just above the collar. “Fuck, Kitty Kat…Your cock feels so fucking good,” he praises heavily, sinking down further. “Stretching me out and stuffing my ass so well.” He lets his weight drop the last few inches and groans as the toy impales him and he can feel the vibration of the harness through his balls. Katsuki’s face is red as he heaves desperate breaths through his nose while Riot pauses to adjust to the ache that radiates from his hole.
Suddenly, Katsuki bucks beneath him with a muffled squeal, defying Riot’s order. Riot doesn’t mind though, recognizing that his baby can’t fucking help it as liquid bursts around the leather of the harness. Riot squeezes just a little harder at the sides of his neck as he raises his hips while bracing his other hand by Katsuki’s head. Katsuki strains against Riot’s hand as his knees crook upwards, feet braced against the bed. When his hips buck upwards, Riot moans when the cock inside him jolts upwards into him. He rolls his hips down just to get it deeper, pinning Katsuki’s hips back to the mattress with his weight. “Good boy, just like that…” he encourages in a low gritty tone even though he knows that the act was accidental. He releases Katsuki’s throat to arch his back as he lifts again and reaches behind him to turn up the vibration between Katsuki’s bent legs. Katsuki dutifully bucks again and screams through the gag and Riot chuckles meanly when that thick cock shoves once more up into his ass. He feels feral as he starts to actually ride the cock cock, enjoying how the thick ridges lining its shaft rub perfectly over his prostate while his heavy leaking cock bounces with his movements. His Kitty Kat’s head tosses from side to side, making his shaggy blonde hair stick up in wild directions as Riot fucks himself with grunts and groans.
Riot nearly cums when Katsuki jerks again with a delectable wail and tears start to trail down his cheeks to mix with the saliva coating his chin. The villain is forced to grab his shaft and squeeze to stave off his orgasm. Next time he’ll wear a cock ring… “That’s it, Kitty Kat,” he snarls. “Fucking take it. Make a fucking mess for me. Cum your fucking brains out while I bounce on your fucking dick!”
Riot shifts his legs under him and until his feet are planted and he’s sitting upright and starts to fuck himself harder over the cock, slamming his ass down over Katsuki’s pelvis while the tension in his abdomen builds from the stimulation over his gland. “Fuck,” he shouts viciously. “God…Gonna ride this cock all the time now,” he swears and grabs his cock to start stroking it in time with his thrusts, balls tightening in warning.
His Kitty Kat is practically senseless and whining below him, neck strained and head tilted back against the mattress as he cums again. Needing to be closer, Riot shifts back to his knees, barely pausing his rolling hips as he once more hovers over his baby, braced on one hand as he works his cock furiously and slams his hips down over and over again. “Gonna cum all over you,” he warns, strained as the coil tightens. “You’re fucking mine, Kitty Kat. Your pleasure belongs to fucking me and I’m going to take it all from you,” he rumbles just before the pressure in his balls explodes and thick ropes of cum begin to spew in wide arcs from his tip to coat Katsuki’s belly. “FUUUUUUUUCK!” he roars, as his vision shakes and pleasure rolls through him in violent waves. Katsuki must cum again because his back arches upwards with a shrill inhuman sound until their sweaty chests bump together before collapsing over the mattress, boneless and limp. Riot’s groan is pulled from the depths of his chest as he continues to unload in heavy spurts while he milks his prostate by grinding down over the cock. “Good boy,” he chants breathlessly as his orgasm tapers and he slowly rises off of the cock.
His boy is limp and gurgling heavy wet breaths through his nose as Riot tries to shuffle off of him, legs feeling like jelly. He quickly presses and holds the button over the vibrator in Katsuki’s pussy to stop the vibration before toggling the switch to stop the one over his clit. Katsuki’s sigh of relief gusts from him as quiet settles over them. Riot unstraps him carefully, mindful of Katsuki’s undoubtedly sensitive mound and pulls the drenched cock from him slowly. A heady whine is muffled through the gag as the tip pulls free of the spasming hole.
“Did so well, baby…” Riot murmurs softly as he sets the soaked strap-on to the side and leans up to unbuckle the gag from around Katsuki’s head to pull the ball from between his teeth. Katsuki’s eyes are closed and deep breaths make his chest rise and fall quickly. Riot quickly tosses the gag behind him and lays on his side to wrap an arm around his shivering boy to tug him against his chest, heedless of the copious liquids drying uncomfortably over their skin. Needily, Katsuki latches onto him and snuggles in close, down deep in the submissive afterglow and completely nonverbal. “Shhhh…you’re okay,” Riot reassures sweetly. “Such a good boy for me.”
Riot cherishes these moments, when Katsuki is soft and tactile. He could lie like this for hours with his perfect hero tucked against his chest, boneless and satisfied. He nuzzles down into sweat damp blonde hair, just breathing in Katsuki’s natural scent and rubbing his palm down his spine soothingly. It’ll take awhile for Katsuki to come up, but Riot is perfectly content to keep him tethered and calm, to bring him down from the high slowly. “My pretty Kitty Kat…” Riot whispers, pressing a kiss to Katsuki’s head. “One day, I’m going to keep you all to myself,” he promises so faintly that he knows that Katsuki won’t be able to hear in his altered state. He makes the same promise every time he has the hero close.
