bad kitty

Summary:

Shouto is a careful, loving master, and a good dom knows that all his subs yearn the most for is to be put in their places.

Not that it's an easy task.

Notes:

I've started this EXACT story as seroshinkami and I've even posted the first part here, but I've got no shame in admitting I've decided to just adapt it to todobakudeku for me to go on with the writing. I've also got no shame in just posting this here so God help me.

Work Text:

A pleased, yet almost eerie laugh left Shouto's lungs, as he leaned back lazily in the armchair. The uncanny smile remained after, while his eyes didn’t leave the yellow page of the book held in one of his hands. On the other there was the black wireless control, his thumb caressing the intensity knob.

"You should see this, kitten, it's truly a bad joke. And all that puzzles me, because the main character supposedly loves this girl he dominates, but I love you as well, Katsuki..." The thumb on the control turned the knob, decreasing the intensity "and that's why I know how to take care of you. And you know, a dom does not bend to what a sub wants. This is how a submissive knows his place. Don't you agree, kitten? Don't you need me to show you where you belong?"

The answer was a strangled moan very much like a meow, albeit unintentional. Shouto lowered the book, laying back, and looked at his boyfriend, right at the clear halo of irises around dilated pupils.

Kneeling on the rug a step away from the armchair was Katsuki, not a single piece of clothing in his body, unlike Shouto, who was still fully dressed in sober, dark pieces, as if it were a day's work.

The only props Katsuki wore were a leash with the sayings BAD KITTY in golden and the binding pieces that held him in place there: his hands tied back, his forearms almost parallel to each other; and knees fastened bent, calves against the back of his thighs. That, and, of course, the strap that held the vibrator inside him, whose control was in Shouto's hand in that moment.

Katsuki moaned softly when Shouto opened up a sweet smile of admiration with his eyes locked on him. The image was beautiful to them from both points of view, and Katsuki wanted to smile back. He would not lack will: the problem was that he was unable to be tender as he found himself in complete despair. He was sweating, breathing short, seeing blurred so dilated his pupils were, so aroused he was, and of course, he was also painfully hard, to the point that a few translucent drops of pre-cum had dripped onto the rug.

Being in Shouto's hands that way was always wonderful, and for that very reason, bordering unbearable. His heart hammered in his chest and his legs were already shaking, but he had no prospect of when his torture would end. The thought went in the same direction, the opposite way: unbearable, therefore, wonderful.

Sighing as if bored, Shouto turned his gaze back to the book, for Katsuki's helplessness. As Shouto was supposedly back to reading a cheap, cheesy sub/dom themed romance novel, Katsuki right away was brought to squirm suddenly, throwing his head back and clenching teeth, feeling that Shouto had increased the intensity of the vibration inside him.

"You know, kitten, I even laughed, as expected, but I guess I'm kind of offended, especially to imagine such a horrible excuse of a sub." He sighed and then closed the book, putting it aside and tucking the vibrator control in the pocket of his pants. "As if it were something she should fight against."

He stood up; Katsuki choked in thin air, dry throat, and almost smiled when he noticed the volume in Shouto's pants; despite all the controlled, indifferent posture, he was also hard. Katsuki could not help thinking how much he wanted to have it in his mouth and throat at that moment, and the cogitation only already made him spasm.

"I mean, don't you like it, Katsuki?" Gently Shouto reached the other's chin and lifted it, making him look up. 

Panting the blond nodded, feeling the hand then caressing his face; he took another small step forward, enough to rub his leg against the extremely sensitive skin of the one kneeling there. Katsuki closed his eyes, mouth gaping, sobbing with every skim and really trembling in a will to push himself against him. It was completely animal and he really breathed in a snarl. As if Shouto knew, his hand slid up his sweaty face and his fingers tangled in the disheveled blond hair, jerking his head back.

"Say it."

"I like- I love it, Shouto. You doing whatever you want with me-" He begged, looking up, and gave a crooked smile. "It is fucking wonderful. I'm yours to use."

The smile on Shouto's side next to a distinct glow from those domineering eyes said the same thing, but the answer was another.

"You love it, hm?”

“I do, I do.”

Shouto crouched in front of Katsuki, and staring at him like that took the little bit of breath that was miserably left in him. What Shouto watched was his boyfriend choking, sobbing, that delicious deplorable state. And that was when he reached out and began to caress delicately - gently too - Katsuki's erection, feeling it pulsating against his palm.

"How do you love it when I touch you, kitten?"

"U-hum, yes, oh, shit, a l-lot." Struggling even to find the simplest words, Katsuki whined, his eyelids fluttering

"Do you want me to take that vibrator off you and put you on my lap instead?" While holding his erection, Shouto's thumb slid around the glans in circles, caressing slowly. "Would you like it?"

"Y-Yes, yes, please, anything..."

Then Shouto brought his face even closer, murmuring the words almost against his boyfriend's lips, who was already rolling his eyes, body taken by spasms he couldn't hold back.  

"Do you want me to make you cum, Kats?" His hand slightly increased pressure and speed to the movement, caressing the full length firmly, making Katsuki writhe, mouth open, moan softly. "To the end, without stopping, do you want me to finish you off, kitten?"

"Yes, yes, please- please don't stop, go on, go on, please, fuck, Shouto..." He begged; but Shouto, instead, held the tip firmly, preventing him from coming and making him growl in frustration.

"If you say anything other than my answer I might end up thinking it's our safe word." He reached the control of the vibrator and turned it down to the minimum. "I'll even turn down the noise to make sure I heard it right. Do you want me to stop, Kats?"

Gritting his teeth, immersed in a haze that almost made him dizzy, Katsuki shook his head, vehemently, hips yearning to jerk forward. Shouto went on.

"So it means you were only being wayward, then, is that it?"

Again the other shook his head in denial, eyebrows angled and eyes in pure anguish.

"No- shit... no, sir, please..."

"Then do not open your mouth except to answer me straight or when I tell you to."  

Then, Shouto stood up and Katsuki whimpered softly, clutching his legs together, shaking, craving with all his heart any kind of touch or friction for his edging body. With all the calmness in the world, he gave his back to Katsuki and took the two steps to the small table next to the armchair he had been sitting. There was a bottle of water on top of it, which Shouto opened, and he drank a few sips from it before walking back to his boyfriend.

"For example, now. Open your mouth."

Katsuki did so, and let his boyfriend give him water in his mouth, gently, until he quenched his thirst.

"Alright there, kitty?" Soft voice, Shouto's thumb stroked his now wet lips.

Katsuki nodded, and then, suddenly, no expression on his face, Shouto just turned the bottle and poured the rest of the content onto the other's shoulders; cold water dripped over his warm body and Katsuki couldn't not cry out, out of surprise mostly, his heart suddenly racing more. Unaffected, Shouto walked around the now wet body of Katsuki's and stopped behind him, bending down.

"You're mine. I'll do whatever I want with you." He whispered next to his ear, carressing his wet cock. "Behave and, who knows, when I get back, I may fuck you stupid like you want me to."

Shouto increased the intensity of the vibrator to the maximum, compensating for the effect of the cold water, and, along with his words and gestures, he made sure not to let him come back from that edge. He stepped back, steps almost absolutely silent on the rug, leaving Katsuki - or that seething, raging chaos Katsuki was by then - alone in the room, whining low and forsaken to his sweet misery.

***

Entering the bathroom, Shouto leaned against the sink, the pose he had kept falling apart for a moment. Looking at his own image, he sighed, his breath heavy. He really loved that, but it didn't mean it wasn't torture for him either. He unzipped his pants and put his hand inside. It always felt like such a waste to get relief alone when the two of them would do anything to sit there, but, well... he had a job to do and a stance to keep. He was a dom, a master, it was his role. And he would comply.

When he left the bathroom, he did not return to the living room. Instead, he went to the bedroom; someone else was waiting for him too. He leaned against the doorway, smiling, and watched for a moment Izuku's sweet suffering as he was lying in the middle of the bed, on his back, blindfolded, a leash on his neck, and headphones covering his ears. The pink plushed cuffs kept his wrists together and fastened to the headboard above his head; his knees were held apart by a retractable metal bar - a simple spreader bar.

Needless to mention, just like Katsuki, there was also a vibrator inside him and a cock ring on the base of that erection preventing him from coming.

Shouto entered the room quietly and held the control of the vibrator that lied on a countertop. The sub wouldn't hear him that easy, because there was music playing on his ears, but yet still he was still very careful approaching him. Izuku had been there for about half an hour, but he had no clue about it at all. He could perhaps count an average of how many songs he’d listened to ever since Shouto left him there, he even tried it at first, but he had already forgotten it.

Maybe he had entered a trance. After eternal minutes he was cathartic, plunged into darkness, filled with the constant, unchanging vibration emanating from his guts and with the perception interspersed with psychedelic electronic music. 

Then suddenly he felt the intensity of the vibration within him rise sharply, without any warning, and could not control a scandalously loud moan that could even be heard by Katsuki in the living room (to his own disgrace, who writhed alone kneeling in the rug).

“S-Shouto? Are you there?” Izuku cried out, his heart impossibly racing. After being teased, tied to the bed, left on the edge, and abandoned for that countless amount of time, he returned. It was like hearing salvation, like being raptured; no one could tell him that there was nothing divine about this rescue. Deep down some reason told him that he would have no relief anytime soon and he was in the same intrinsic duality of Katsuki; he wanted more of it, and wanted it to end and get relief as soon as possible.

The answer was not verbal - a sharp pain radiated through his chest as he had his nipple pinched and then kissed, the texture of his tongue and lips softening the sensation. 

He felt the weight on the bed beside him and the tips of his fingers that were on one nipple slid to the other, stroking the pulling as well. There was more moaning. The hand on Izuku's chest slid down his body to his belly, where he touched only with his fingertips, circling the groin to reach his thigh, caressing his skin softly and provocatively. 

Izuku writhed at the touch as if his body were made entirely of erogenous zones, oversensitive. His chest was rising and pushing down in deep, forceful inhales and exhales. He caught his breath as he felt a greater pressure on the mattress and assumed by the movement that Shouto was crawling up the mattress and stopping between his legs. That already made him squirm, which Shouto watched with satisfaction as he grasped the metal bar of the leg spreader and pushed it toward Izuku's chest, leaving him there with his legs spread and bent against his torso, at his complete mercy. The movement drew yet another loud moan from Izuku, frightened and horny as he felt at that moment. 

Then the music stopped and the headphones were removed, but the blindfold was kept. Izuku gasped, dizzy. The heat and presence upon his body seemed to come from all sides.

"Keep quiet, Izuku." 

Shouto's voice was like another kind of music and also sounded almost psychedelic. He was dying for more touches, for more Shouto, but he breathed, licked his lips and swallowed hard, his breath still deep and forceful as he felt his erection throbbing with the slightest of touches. Izuku sighed, biting his lip, feeling his heart race in his throat.

"I'll let you go now and take you to the living room. I’ve told you already, but I'll repeat it, for the last time: there’s no playing brat today. I’m not allowing you to disobey this time. You don’t call any of the shots here and I might as well leave you stuck without any relief until tomorrow if I want to. If you understand me, nod.”

Shouto's orders so firm that they made him shiver, and if he wasn't completely hard before, now he certainly was.

"U-hum." He nodded and basically groaned, biting his lower lip for a moment.

Shouto took his blindfold out slowly. The green eyes opened slowly, adjusting the focus because of the the light and watching Shouto over him, the two colors of his eyes and hair like a mirage. Staring at him, serious, he kept one hand holding the leg spreader.

"Repeat: I'm your good boy and I'll do everything you tell t to."

All Izuku wanted was for Shouto to open his pants and to take him right there, in that wonderful and so propitious position. If Shouto hadn't taken action in the bathroom about his own arousal, he would have a harder time resisting.

"I'm your good boy..." Izuku gasped. "...and I'll do everything you tell me to."

"That's about right. Good boys get rewards..." Shouto whispered against his lips before kissing him, not deep or slow as he wanted to, but thirsty and quick, purposely making the wish for more to remain. “...but you two were really, really bad boys, and that alone won't be enough.”

The hand that didn't hold the spreader then came right back at Izuku's face, slapping him hard. Thumb and the other fingers clutched his cheeks, on both sides of his face, making him pout.

"Shall we?"

***

If the seconds dragged themselves whispering inside his perception or if Shouto had indeed been gone for an eternity, Katsuki could no longer tell. His legs and bound arms hurt, but nothing matched the state of his arousal. He was so on edge that seemed to dissociate from reality, all throbbing on every edge, as if the pain itself has released buckets of endorphins inside his body.

So he heard the footsteps in the hallway and the living room door opened, his first impulse would be turning to look, but he heard an incisive "Don't you dare look back." 

Guided on a leash and with his handcuffed hands behind him, Izuku entered the room and saw Katsuki wet all over, bound hands and legs, kneeling on the floor. So Izuku even froze for a second and muttered a "fuck" that he was sure Shouto just let pass. It was just too beautiful to react otherwise. Shouto knew very well. He wanted to catch every drop that had not yet slid down his body with his tongue, wanted to have fucked Izuku in that bed, wanted so many things he would not do at that moment that he had lost count. His mind should stick only to his plans, the strict rules, the script. The desire was for another moment, and it would only increase.

In Izuku and Katsuki, it was already coming out of their pores, burning their lungs, radiating from their bones. When Shouto brought Izuku on a leash and ordered him to kneel beside Katsuki in front of his armchair, it was as if they were tamed animals. Increasingly unable to think, increasingly overwhelmed by instincts, all that was left of their self-control fixed on being silent and obeying. 

Standing in front of the two of them, Shouto opened Izuku's mouth wide as if to make him suck him off, but it was just to give him water. He would always take care of them. While they feared what would happen, it had never been a real fear. They would always feel safe because even when Shouto slapped them hard in the face he would do it just because they liked it so much.

Then Shouto sat in the armchair in front of them. He crossed one leg with his ankle resting on his knee. He clasped his hands and sighed, causing Izuku and Katsuki to swallow hard.

It was true, of course they didn't really fear what would happen to them. That didn't mean they wouldn't suffer a lot on his hands, even if it was pleasurable.

Izuku looked at Katsuki, but didn’t dare to turn his head, however much he wanted to. Seeing him in that state, really submissive and not even trying to disobey, melted his mind. If there was even something solid yet to melt. It was as if everything had already smelted and he was undone. 

He looked at the master and almost smiled, but still couldn't. Something itself would, but it wasn't that simple.

"Well." Shouto let his head fall to the side. "You both know you’ve been naughty boys. Imagine if I let you believe you should rebel. I worry, you know? If you think you have a right to be dominant. That you can do this to me. A submissive gets lost without their rules, I'd never be this inconsiderate to you. You both deserve punishment. You both tried to take my place. But one of you was meaner." He stood up, making them both swallow hard. 

He walked slowly around them, starting on his right, going around Katsuki. Then he bent down behind Izuku, who sobbed. 

“This time you escape. That doesn't mean I'll just let you do what you want, ”he whispered, that purring sound vibrating beside Izuku’s ear as he released his wrists. Izuku no longer had the vibrator inside him, but when Shouto kissed the back of his neck and neck as he let go of his hands, he shivered so much that his legs trembled and his knees faltered.

"Release Katsuki for me. Carress his skin a little bit in the meantime." He stroked Izuku's hair to one side, tilting his head, and giving him more kisses on the more exposed neck. "Just don't get anywhere near his groin. Other than that, try to entertain me, sweetheart."

He got to his feet and returned to the chair, leaning back and sighing as if to watch.

Izuku's and Katsuki's eyes met and there was a brief apology before the fire took the greenish eyes for good. A moment of sanity before he got on all fours and predatorily crawled the two steps separating them, a sadistic smile so unlike him taking over his expression. 

Katsuki held his breath as he approached; closed his eyes as if in an execution he just accepted the shot. It was his damnation now, and he must soon be consumed by the flames.

Blessed it be.

Those awfully skilled hands on the velcers and buckles would hardly have any trouble setting him free, but of course Izuku spent more time on it than necessary. Kneeling behind him, he caressed his thighs from knee to hips, front and back, to loosen each leg. He kissed his shoulders and bit his nape, and it was only when he heard a "shh, calm down" from Shouto, who woke him up to how greedy he was. He wanted to devour Katsuki there within the reach of his hands, he had already hugged him and wanted to push his hips against his back. Honestly, why not, slide his pleading cock into that fully prepared body of Katsuki’s, which was just begging to be filled. He filled his hand with golden strands and slowly pulled Katsuki's head back before sliding his hand down his spine. Katsuki arched his back with every inch Izuku's fingers touched, slipping all the way to the end - when he removed the prostatic vibrator, which slid easily into his lubricant-filled hand, making it very clear how aroused and ready he was; Izuku moaned in despair along with Katsuki.

Vibrator turned off and removed. Legs freed. Katsuki stretched his arms down and they hurt on the strained joints.

"Izuku remains still where he is now." Shouto said, then patting his lap, on his thigh. "Katsuki, here." 

Katsuki fell in all fours and approached the armchair. With pleading eyes, he knelt between Shouto's spread legs and sat on his heels.

He didn't want to know how, he just wanted Shouto to use him. To do anything to him, whatever he wanted. Please. He was his toy, so he needed to be played with. That was the magic of that kind of situation; to be reduced to that, a fucktoy, stripped of his usual pride, no need for shame. Suddenly Shouto grabbed him by the hair, his fist clenched in blond locks, a dubious growl of pain and satisfaction leaving Katsuki's throat.

"No. Lying on your stomach, on my legs.”

Katsuki's eyes might have even sparkled at what he believed he understood what Shouto would do to him, and Izuku lifted both hands to his mouth to hold back his own moan. 

“Izuku, get the gagball over there for me. ” 

Biting his lip, Katsuki knelt beside Shouto's legs, swallowing hard. He laid with his chest and belly on Shouto's thighs and Izuku handed their master the gag with the small black ball in the middle.

Katsuki smirked and bit the black ball, allowing the other to close the gag buckle behind his head. Shouto’s left hand then gripped a handful of Katsuki's hair, lifting his head high enough that he was looking straight ahead rather than down. The submissive's hands clenched on Shouto's pants expectantly, muscles tense.

“I'm so sorry, kitten. You know I love you. It will hurt me more than it hurts you, "was the phrase before his hand rose." Take a deep breath. "

Katsuki did it, and when that hand came down and hit his asscheek in a hard, loud smack, he flinched, in the initial pain. The stinging spreads, radiating hot, and he writhed. The pain from spanking - oh, Katsuki already knew it very well - was distinct from the others. It hurt sharp, then burned. As he felt it tingling, his fingers slowly dragged on Shouto’s pants, grabbing, and a groan scratched his throat, suffocated by the gag. 

One more slap on the skin, causing it to flush even more. The gag that Katsuki was biting increased that sweet anxiety and the helplessness was consuming him along with all the pleasure hormones in an absurd incoherence. He couldn't utter anything coherent or keep himself from drooling, saliva draining down his chin and neck as he was spanked.

Maybe it was a punishment for Katsuki, but for Izuku was like the equivalent: just watching without participating. It wasn't who was vilifying that soft skin, marking it, nor who was receiving the mark. He was abandoned and yet he was too lucky to have the privilege of watching. Shouto let go of Katsuki's hair and let him hang his head forward, panting. 

And one more slap. And another. Katsuki really was in a catharsis too deep for anything but the hypnosis of that cycle. The humiliation of still having someone watching such a degrading punishment would only be so attractive because it was the three of them. 

If there was no pride to get in the way, the only instinct was left under these sophisticated and unnecessary feelings. The hit, the burning, the tingling and the waiting. He caught his breath, his heart pounded, and again. 

Izuku felt like a dog waiting for the owner to just whistle so he could attack. He trembled. He gripped the rug so that he would do nothing with those already shaking hands.

Shouto liked to leave his fingers a little apart when he spanked Katsuki, to see the reddish imprint of her fingers perfectly marked on the pale skin. This was his selfish pleasure, which was nasty in his fetish. It was his. His to have and to use. He chose to care and love, but every time Shouto Todoroki was simple and calm, it was in domination that everything fell apart beautifully. Here he only took what he wanted, marked his territory, made it clear that his wishes would be satisfied. He had Izuku in anguish in front of him and Katsuki undone in his arms, both thanking him for it. Yes, even Katsuki, short breathed and yelping. It was already hurting enough but he couldn't signal for Shouto to stop - he wouldn’t, ever. He wanted more, how much Shouto wanted to give, and he had no idea if he should or shouldn't. 

Feeling his own hand hurting, Shouto smiled the lightest. The pleasure of the specific pain was in him too, the specific hot tingling. Then when he raised his hand this time, he watched Katsuki flinch, and the sadistic grin widened. 

Instead of slapping hard once more, palm and fingers touched the asscheek gently instead. He stroked the red welt he caused.

"You're a good kitten, Kat." The fingers delineated the drawing of his fingers on the skin.

Then pulling blond hair, Shouto pushed him off his lap, enough to be rude. Katsuki dropped to the carpet, pain and pleasure blinding him.

Everyone in the room wanted to grab each other with everything they had. They wanted more and wanted revenge. They wanted to submit and wanted to obey. The truth was that they were already on the edge, but there were decisions to be made.

"Katsuki..." Shouto exhaled and leaned back in his chair, sighing. “You can take off the gagball. Then you put Izuku sitting here on my lap, okay? ”

Izuku's eyes widened and it was always a surprise to feel his heart race because he always felt that the blood was beating at forbidding speeds inside his veins. 

"I-" Izuku tried, but Shouto did a 'shh' to him and gritting his teeth again seemed to make him explode. He needed to scream, trembling not to do anything. In his already distorted perception, as a surreal dream, Shouto was a divine law, and perhaps it was very god-like indeed to insurge such fury in the worship. It was a shiver that constantly crawled under Izuku’s skin but never came to fully bristle. It made him want them to scratch, to bite, to take. Perfectly mundane of him.

Taking a deep breath, getting up to his feet, Katsuki pulled the gagball out of his mouth, the fake black leather gleaming wet as well as his lips and chin. He gritted his teeth and the way he was panting, head down and turning his darkened gaze to Izuku, was more of a hungry wolf than a kitten, no doubt, and a part of Izuku’s hoped he would lose the little control he seemed to have left.

But Katsuki grinned vengefully, and Izuku tasted his own poison as the blond bent down once more and climbed on all fours on top of his body. He felt perfectly preyed and wanted every filthy pornography he was certain to have taken Katsuki's imagination as their eyes met. He was feeling defiled, used against Shouto's will, as the most abominable sin. Izuku's knees repelled themselves beneath his body and Katsuki growled low, stroking the other’s lips with his thumb slowly.

“How do you want him, master?”

The whole scene had been hypnotic enough to take Shouto's concentration off and take him a moment to respond. Katsuki's slow, strong movement, which, on its feet, bent down and crawled like a predator, followed by the voice that enticed them to perdition like letting itself into a whisper in a dream. Izuku dropping his body onto the rug, resting on his forearms, his legs spreading almost like a force of nature. 

How beautiful they were was obscene even before it was erotic. It was outrageous, incoherent, everything he wanted most. He was already hard in those pants, too, and was slowly but steadily losing his ability to reason. When he realized, his fingers were gripping the arms of the armchair. He cleared his throat discreetly.

"His back against my chest."

Katsuki crouched and pulled Izuku’s legs to around the waist, hugging him against his body. Izuku clutched his shoulders like holding onto a branch in a waterfall for dear life, sinking his face into the curve of his damp neck and taking a deep breath, rolling his eyes with desire as his scent filled his lungs. He growled low in despair as Katsuki stood and his arms adjusted both bodies together, groin against his belly.

For a moment they stood, Izuku trembling not to rub against Katsuki's torso and Katsuki to not pull him down and have his neglected erection finally satisfied, slipping to inside that body that would always accept him so well.

"Hey. Over here. You two.” Shouto snapped his fingers. “No having ideas.”

In fact they were on the edge and Shouto knew it. When they looked at him, the master's voice lost its cordiality. It was firm and relentless.

"Izuku on my lap now or we start everything all over again."

Katsuki walked over to him and left Izuku on his lap, back against Shouto’s chest. In those arms, Izuku spread his body as if stretching, wanting as much touch as he could, grunting once more.

Shouto's arms wrapped around his slender torso and his hand slid down his sweat-damp belly. 

“Will you remain obedient, Izuku?” He bit Izuku's ear and whispered against it. “Will you deserve your orgasm now?”

The mere word in Shouto's voice behind him and the sight of Katsuki kneeling in front of them made Izuku moan and spasm.

"Y-Yes, daddy ."

Shouto chuckled, half a smile remaining, and his hand reached the groin. He hel the ring that held Izuku's orgasm back and pulled it slowly from his body to take it off, relishing on how much Izuku writhed when his fingers slid the length of his cock. Then his arms hooked under each knee of Izuku’s and he pulled them up, entwining his fingers behind Izuku's nape. It was a position that left the sub with his head low and his back all bent, completely exposing him to Katsuki.

“And you, Katsuki? Do you want this? ”

Katsuki hesitated. It wouldn't be that easy. It was a trap. 

Which he would fall for knowing it or not. Because there was Izuku, chin pushed against his chest, green eyes begging under angled eyebrows, legs wide open and fully surrendered. His body begged for him. He swallowed hard.

"Yes."

"Yes, what?"

"Yes, please, daddy ...?"

Not that it was the first time they'd called him that, not at all, but it amused Shouto, in a slightly funny way. He was pleased with that, with all forms of submission.

"If it's with the dildo, you can do whatever you want with Izuku. But go all the way to the end."

A snort made it out of Katsuki's dry throat, almost a laugh, but wouldn't he dare to laugh - or would he? He didn't know if he was laughing, and if so, of what; if mocking of himself because he knew it was too good to be true, if he was pleased to take revenge on Izuku for teasing him, if it was of his own disgrace or out of sheer nervousness. 

What he knew was that coming back with the dildo in his hands and seeing the lovely despair in the green eyes was truly powerful, and that he would make him fall apart. He would make him beg. It was the vicious cycle; if he was being tortured, at least he would take someone to the pit with him.

Shouto released the fingers that were entwined behind the back of Izuku's neck, allowing him to lie against his torso, resting his head on his shoulder, but kept those legs wide open. As Katsuki knelt between Izuku and Shouto's legs and slid the dildo in, he watched it enter Izuku's body easily, at once and steadily, accompanied by Izuku's breath as a loud cry as he threw his head back, squirming. He had Shouto kissing his neck and shoulders and keeping his legs open for Katsuki to pull his arm back and push once more, perfectly and terribly slow. The touch on his prostate was continuous and slow, and in the next movement of Katsuki's arm, it was like a wave going back and forth on the beach. It took him away completely, peaking in one spot and spreading slowly. And, to his damnation, to blind him once and for all, Katsuki's mouth found the tip of his damp cock and in the next moment it was in his throat.

Spasms shook Izuku’s entire body and Shouto covered his mouth so he wouldn't scream, because he would, he surely would, as his whole body lost its grip and it was Shouto only the one to keep him in place. Katsuki, in turn, was a complete animal, Izuku there in his hands, so close to cumming but so far from satisfying him back. He was breathing through his teeth and forcibly when his mouth wasn't busy with Izuku's cock, licking slowly and sucking just hard enough for the orgasm to be a wave rather than a climax. Izuku’s legs trembled, his breathing was broken, hesitating, and in the middle of wanting to scream and really moan, he actually heard himself begging Katsuki to continue.

"Please, please, please don't stop." Izuku grabbed Shouto's wrist. He was feeling, so close to snatching him, so powerful that he thought he would lose consciousness, and if they ruined that orgasm there he could honestly start crying. "Please, I’ll do anything, please ..."

"I won't stop." That's just what Katsuki said, cavernous voice, before being back to sucking him off. The insistent, endless thrusts, never resting, never increasing or decreasing, drove him to dizzying levels of pleasure. And the orgasm would come in a way he would never believe, even if it wasn't his first time. 

Call it transcendental again. It was like the cliché of seeing stars as he closed his eyes, the heat spreading from his insides to his limbs as it ran through every tiny vein of his body, and his own moans in tunnel hearing, the last thing being an omnipresent whisper of Shouto telling him to let go. Let it go, because they would hold on.

Shouto would hold on, but that was all he could do about it, because after what he was going to watch, he only could think of fucking them wildly as the epicenter of everything he had to control that night. Izuku's erection against Katsuki's tongue was ridiculously wet, but he didn't ejaculate. From Izuku’s mouth came words he could not understand and animalistic growls.

Izuku’s hands curled into golden hair as Katsuki continued, both with the dildo and his mouth; this time even firmer and more resolute, sucking him off untill deepthroating. He mumbled more incoherent things, Shouto kissing his neck and biting his shoulder, and before regaining control of his body he was overwhelmed by another orgasm; this time punctual, not so powerful but like an apex, enough to shake his whole body this time and drain out all his strength, when he finally ejaculated. He was at its highest peak, undone and recomposed, resurfacing to another level of consciousness.

Wonderfully ruined, Izuku experienced this catharsis without even thinking how to get back from it or what to do from there. He was just lying in Shouto's arms and feeling his kisses on his skin, staring at the ceiling as if in paradise.

Katsuki swallowed it all and it was the end of the line for him. He left Izuku there on Shouto's lap like a rag doll. He wiped his mouth, let the dildo fall to the carpet and his arms along his body. He stood there, looking at Shouto, as if waiting for the order, but it was much more a jar of nitroglycerin that if stirred the wrong way would explode whether he wanted to or not. It was very clear in his eyes; there was no use in try to tame him anymore. Shouto wouldn't even try. He had already transcended too, and feeling Izuku losing himself completely like that in his arms, almost losing consciousness in his lap, was the end for him as well. Staring at Katsuki as if they didn't even want to blink, Shouto sentenced:

"It's your turn now."

Katsuki picked Izuku up on his lap and it was harder when he could barely steady himself to help him out. He left him on the couch beside them and as he laid him, he was enchanted for the hundreth time by every trace that outlined that exhausted expression, the reddish freckled cheeks and parted puffy lips; Katsuki was taken by that duality that made him want to cradle him inside his arms or wrap his hands around his neck just to hear him beg his name. Every drop of sweat on his flushed skin was like a treasure. Surely he thought of kissing him before realizing that whoever his lips rested on now he would no longer be able to let go, and he stood up again, giving Izuku his back. Almost laughing, completely dizzy, Izuku tilted his head and watched, dying to participate but definitely unable to move.

He saw Katsuki go back to Shouto's armchair. He knelt on the floor between his knees, hands sliding down his thighs with something indefinable between idolatry and possessiveness. It was two steps away, but it was not directly under Katsuki's gaze, he could not taste all the nuances of what it showed. Maybe even Shouto, who was the direct target, couldn't translate. Neither he wanted, in fact. He just wanted whatever came from Katsuki now, whatever it was.

Shouto then began to unbutton his shirt, and expecting Katsuki to watch, he smirked as he loosened the second button much more slowly than necessary. It was addictive, what could he do?

But it had been the wrong choice, or the perfectly right one. Anyway, the last straw for Katsuki was the tiniest. He grabbed both sides of Shouto’s shirt and tugged it to both sides, popping open some buttons and ripping others, with sounds of them bouncing off somewhere on the floor of the living room. His mouth found Shouto's thorax and he bit and kissed as if he needed it to survive.

“What-” Shouto choked, because what he wanted to come out as a protest came out as a moan, and he needed to start over, “what do you think you're doing, Katsuki?”

The furious look under his brows froze Shouto's blood and made him throb in his pants, which Katsuki unzipped now.

"Taking what's mine," the phrase came out hoarse, dense, and followed from his hand lowering Shouto's underwear and holding his cock as he freed him from the piece of clothing.

"You're going to pay-" Shouto tried, but Katsuki covered his mouth with his other hand before bending down and basically swallowing it at once - no hesitation before sucking him off with all his will. same. Shouto rolled his eyes, one more movement away from giving up completely. He pulled the blond hair hard to keep him from going on, pushing Katsuki's head back.

"Don't you want it, Shouto?" Panting, his head hanging back, that already crazed Katsuki growled in spite of some dry, half-manic laughter, saliva running down his chin. "If I don't sit on your cock I will sit on a dildo and come calling your name and you won't be able to do anything to stop me."

Shouto narrowed his eyes, but felt himself seething inside the clothes he was still wearing.

“I should have punished you a lot more. You're not a good kitten. ”

With one finger, Katsuki showed the collar that was still around his neck, which read“ BAD KITTY ”.

Damn, Shouto snorted. 

"Make it count, then."

Even outside the script, how could something so incredible be any less than right? Katsuki so blind with desire that he didn't want to know anything anymore, rules, roles, punishment now or later, needing him, only him, with everything he had, and screw everything else. Riding him like that, both legs at his sides in the armchair, smiling almost maniacally as he watched the helpless gaze of his said master. Wasn't that what they had sex for anyway? To be of each other, perfectly, wildly?

Damn him, Shouto snorted again before squirming as Katsuki lowered his body and sat slowly on his lap, letting himself be filled with his cock. 

Izuku was still shivering and barely able to sit back down, but if his body didn't respond, maybe even his spirit would have been aroused by such wonderful scene. He wished he had filmed it, but he was sure he wouldn't forget it so easily. Shouto removed the cock ring that delayed Katsuki's orgasm and as his hand slid down the length of that reddish, moist, aching erection, Katsuki shivered all over.

Without warning, then, Shouto slapped his face, hard, causing with an immediate acceleration of Katsuki's already tachycardic heart.

"If you're going to do it, go for it." Shouto said still deadpan, two fingers hooking on his leash, still not giving up dominance, and making Katsuki only smile more in that same insane way. He grabbed Shouto's neck with both hands - instinctively the right way, fingers clenching under his jaw but not pressing the trachea.

“I will, master .” This time the tone was sarcastic, and Shouto couldn't help but grin, feeling the chill of falling dizzily in that absurd pleasure, his hips moving almost against his will. An up and down movement of Katsuki's body and his hands slid to Shouto's shoulders as the face under his gaze was already flushed hard enough.

It would take just a couple of minutes, however, considering their level of arousal, and Katsuki surrendered to his own particular pace: slow and strong. He let a moan claw up in his throat every time he felt the entire length rub against the specific point that radiated pleasure through his insides and the dry sound accompanied it when it reached the deepest, the hands on his hip helping with the impact.

By then Katsuki was already throwing his head back and moaning loud. Shouto pulled his torso close to his, hugging him against him, Katsuki's hard cock pressed between their bellies. Moving up and down at the same incessant pace, the sensation that made Katsuki’s legs tremble grew steadily, like water flooding a closed room, about to burst the windows to spurt out. Eyebrows in angle, Katsuki was already whimpering, and Shouto looked up panting, both admiration and desire to see him crumble in his arms. He pulled him harder down at the same pace, the impact as hard as possible. At one last moment Katsuki ran his hands through the thin, straight hair of the other, each hand grabbing a handful of one color, and bent down to kiss him, which was much more a collision of mouths and the incoherent and brief touch of his tongue on the other's lips. 

Soon he was moaning too much against Shouto's mouth and his eyes rolled. Shouto locked his closer embrace, the orgasm he felt about to snatch the other dragging him along, and felt him jerk violently, without grace or posture, what happened to him when he was taken by a prostatic orgasm.  In the echo of his own demand, he experienced such ecstasy, such an idyllic reality, where it was cradled and nestled, as if they were embracing in the middle of a volcano. It was all inside him, and that didn't drive him to exhaustion, no matter how overwhelming.

Obliterated in Shouto's arms, Katsuki might have his eyes open, but still everything was dark and throbbing, as if dragging the instant you look at something too bright. He couldn't tell if the moans were echoes or if it was him again. Shouto bit down hard on his chest to mark, and the pain confused Katsuki’s senses maddeningly. When he realized it, he had dug his nails into Shouto's back. It took just a single movement of his to make Katsuki cum, smearing between their bodies.

The pressure around Shouto when Katsuki ejaculated was too strong, pulling him, too tight, too hot and too intense. White and red strands glued to Shouto's sweaty face as he lowered his head and rested his forehead on Katsuki’s shoulder and, in a strangled, short moan between his teeth, spilled into him. Even if for a moment, pleasure took the place of everything; strength, reasoning, conscience.

And static, as if sensing a dense fog dissipating, their minds were empty for an eternal moment. Katsuki knocked his body against Shouto's, who dropped into his chair. 

They sighed in each other's arms, still immersed in that delicious sensation. If there was anything more incredible than doing all those depravities with other people, it was being able to look into each other's eyes and not be ashamed, even if they could laugh at it later; not feeling remorse for violent marks on the body, and feel cared for even when degraded. The game was over tonight, and it would be nothing but a sweet, torrid memory of the countless things that would always keep them together.

Still...

“Izuku, my darling, keep note:” Shouto pushed Katsuki off of him to get up, dropping him to the rug. “Next time the two of us have fun, this piece of shit right here will be tied up and gagged in the corner the whole time.”

It was a game, yes; but it didn’t mean he would allow Katsuki to win. His submissives needed to know their place, after all. It was what they needed, so he would always give it to them.

For now, though... aftercare might be the ideal.
