"We’re late," Hitoshi sing-songs to Shota as they run through the crowd, their eyes set on the amateur purse snatcher they’re after.

"Nothing we can do about that now," Shota grumbled. His wrist flicks his capture weapon out, the material snapping around the person’s ankle and pulling them to the ground. "The kitten’s fine. She can wait a bit longer."

"Think so?" Hitoshi asks as he gets close enough to bring his boot down on the thief’s wrist, preventing them from reaching out for the dropped bag once again. They groan in pain, activating their quirk to summon a dagger of light in their other palm. They swipe the blade of energy at Hitoshi’s leg, cursing at him all the while.

"Fucking meddling heroes!" They scream, blindly wielding their weapon. "Can’t mind your own fucking business! I—" Their screeching comes to an abrupt halt, their eyes dulling and muscles relaxing.

Hitoshi sighs, aggravated by the lack of a challenge and disappointed with the abundance of stupidity. If he was going to be spending his time away from home, away from his new kitten, then he wanted the patrol to be worth his time. "I didn’t even have to trick you into opening your big, fat, fucking mouth." It’s not a moment later that Aizawa is slapping a pair of quirk-canceling cuffs onto their wrists, ending the shit-show of a robbery quickly. Hitoshi silently commands their perp to stand, guiding them to follow wordlessly to the nearest precinct. Shinso is quick to pick up their conversation again. "I just hate leaving her all alone. She’s still in the training phase."

"That’s how kittens learn," Shota reminds. "We can’t be home 24/7. She needs to learn how to behave even when we’re not there."

Hitoshi’s shoulders slump and he heaves out another sigh. "I know, I know. I still hate it though. Her little sad eyes and pitiful mews are like fucking daggers to the heart." Aizawa raises an eyebrow at the pun, but whether Hitoshi meant it as such, he doesn’t address it, so neither does the older hero.

"You’ll spoil her," the dark-haired man scoffs. "You can’t just pamper her. You gotta look away from the eyes."

The deep-seated sigh that escapes the lavender-haired man’s mouth causes the sensei to roll his good eye in exhaustion over the same tired argument. "But what if she hates the potty pad and won’t use it? Or what if—"

"Look, kid, you gotta trust me, okay?" Aizawa interrupts. "I’ve been through this before. She’ll learn. The training phase will be over sooner if you don’t coddle, alright?"

Hitoshi agrees with the older man, but his tone is less convincing. Not that it matters much as there is little that can be done about it now. They’re already late, the few minutes it takes to make it back home won’t make much difference. But their kitten will be fine in the amount of time it takes to travel to their shared apartment.

Once they open the door, they’re greeted with the sight of their pretty new kitten, sitting right where they left her before their patrol shift. Hitoshi chuckles at the sight and coos at the little creature, quickly making his way over to pat her head and scratch behind her ear.

"Hello, kitten, did you have a good day without us?" Aizawa snorts at the question, knowing they won’t receive a verbal answer. He looks over your quivering form and the puddle beneath you. Your face is flushed in humiliation and tears trek down your face, your eyes glassy as you look up at the two men. Shota tries his best to ward off the obvious sadistic pleasure he gets at seeing you still bound to your spot on the floor and the potty pad they left under you full, but he can’t help the twisted upturn of his lips at the sight. "Aww, see, sensei? We were gone too long! Our kitty cat made a mess of herself." Hitoshi grants mercy upon you and switches off the vibrator taped to your overstimulated pussy, slowly pulling it off. You’re finally able to catch your breath, and you attempt to gulp down cleansing breaths but the muzzle over the bottom half of your face makes it hard to do so.

Aizawa squats down to your level, observing the golden pool beneath you. His huge hand cups your throat, the touch gentle but the power evident by the simple display. His gaze gauges you, his head tilting to the side as he wordlessly watches you. "I’m gonna take this off, and you’re gonna be our good girl, yes?" His eyes bore into you, waiting for a response. You finally nod. "And good girls don’t speak unless told to, correct?" You nod again, knowing better than to hesitate a second time. Aizawa smirks, lightly patting the side of your face approvingly. "There we go. We’re learning." His fingers work the clasps of the maw-shaped muzzle, gently working the suffocating contraption off your face. The moment you’re released from the muzzle, you gulp greedily at the fresh air, the unobstructed oxygen filling straight into your lungs. Good thing too. You weren’t sure how much longer you could have been in that thing while being so close to panicking. He gives you a moment to catch your breath, scratching gently behind the ears clipped into your hair. "Now, how long have you been sitting in your mess?" You blush brightly at the acknowledgment, but you refuse to look down at the evidence of your indiscipline. You look towards the oven’s digital clock, and your shoulders slump when knowing the answer.

"T-two hours, sir," you whisper. Your voice is rough and quiet, not only from disuse but also from the lack of hydration. Using the little cat water bowl was much harder to do with the leather muzzle on. You try your best to ignore Hitoshi hissing through his teeth at your answer. Shota tsks and shakes his head.

"Did you get permission to relieve yourself?" He asks. You hesitantly shake your head. His hand claps down on your thigh and you jump. "Words. We use words now. You speak when we’re not actively playing pet. We took you out of pet play when I asked you a direct question and you answered with words. We’re training, so this is the only time I’ll be telling you this. You’ll go back to being a speechless pet when I say so. You understand?"

You go to nod again but manage to stop yourself and mutter, "Yes, sir."

"I’ll ask again," he says lowly, his fist closing around your throat once more, but not so gently this time. "Did you have permission to go?"

"No, sir," you barely manage the words, your voice shaking almost as much as your thighs.

"You got anything else in here?" Shota pokes at your tummy harshly. Before you can respond, Hitoshi slides behind you, an arm caging around your shoulders and pressing your back flush against the front of his body as his other hand presses down on your bladder, pushing out anything remaining. You whine as the last of your piss dribbles onto the overfilled potty pad, the warm liquid tickling over your extra-sensitive cunt. Your thighs tremble harshly, your hands clenching against them and pulling at the restraints keeping your wrists attached to your thighs. Hitoshi laughs at your struggle. He presses your body back into his own once more, hands roaming your rope-clad figure. He squeezes the bits of flesh that spill over the tight bindings and runs his fingers delicately over your quaking thighs. Shota grabs the leash hooked to the collar around your neck, giving the material a yank.

"Sorry, kitten," he sighs, "but you have to learn." He’s not sorry. Not at all. He was actually elated that his plan was executed perfectly. It’s why he insisted they finish their patrol without skimping the final few minutes. That’s why he made Hitoshi chase that last criminal with him, the one before that, and the one before that, despite going over their scheduled patrol time. And as he tugs on that leash cord taut, your collar straining against your pretty neck as he pulls you over his lap, he knows it’s all worth it.

He loves having you on your knees, shuffling across the floor on reddened shins towards the bedroom. He loves the sight of your sticky thighs as they press together shamefully. He loves bending you over his lap. He loves that the angle shows off your pussy glistening with your creamy juices and golden release with your perky ass pressed into a presenting pose. The view reminds him exactly why you were the perfect pick for their pretty new kitten. So eager to please that you didn’t even object to your alleged mistake. Good pet owners are better about punctuality so they can take care of their helpless babies. But their precious pussy cat is just accepting her punishment without arguing like a brat. Oh, yes, you were definitely the right choice. And now, Shota can take this opportunity to teach Hitoshi how a good owner disciplines their kitten.

Aizawa’s rough fingers dig into Shinso’s cheeks as he pulls the younger hero’s reluctant attention onto him instead of your dripping heat. "Pay attention, Toshi," he whispers. "How many do you think she deserves for making such a big mess with permission?"

"Well," Hitoshi starts, voice strained looking down at your dirty ass, "we were late."

Shota lets out a heavy sigh. "And good kittens should know better. We laid out the rules, it’s her job to follow them."

"But isn’t that unreasonable?" Hitoshi asks, a push-over whine to his tone.

"I was gonna give her five, but ten it is," Shota decides. Hitoshi looks as if he wants to protest, but Shota doesn’t leave room for argument. "If we’re not strict with her in the early days then we have a brat on our hands. You want that, Toshi?"

Hitoshi’s lip quirks up at the corners, imagining his bratty little kitten. "Well…"

"No." A rough, calloused hand smoothes down the globes of your cheeks, goosebumps following its trail. You do your best to remain still, knowing he’ll be harsher on you if you flinch away. You’re a quick learner that way. His fingers wind the leash around them, yanking at the fabric. You look up at your master with wide, innocent eyes; the kind of eyes that make his pants tighter. He pinches the sides of your face between his fingers, blunt nails lightly digging into your cheeks. He speaks slowly, ensuring your little, kitty mind comprehends his next words. "We’re back in pet play. The only sound you can make is cat noises. I only wanna hear your little meows, kitten. Understand me?" You nod, offering a small mewl and nuzzling your cheek into his palm.

It was like a switch went off in your head the moment he confirmed pet play was back on. Your movements become more fluid, more soft, more cat-like. You really play into your role as their pretty pet so well. And when Hitoshi slowly works the fluffy, pink toy into your puckered hole, you easily arch your back as if he were playing with your actual tail. You slip into your kitten mind-space so easily, that it’s as if the paws and tailpiece were mere extensions of your body. Hitoshi was so nice to lube up the toy for you, but his quick work-in of the plug leaves your hole to clench around it, keeping it snug and in place. When Hitoshi tugs at the tail, it feels as if it’s a part of your body and you arch with it, presenting prettily over Shota’s lap. Hitoshi’s fingers comb through the toy’s fluffy fur before his touches scratch up to your back. His digits work your sore limbs out of the restraints strapping your wrists to your thighs. He works at the stiff muscles in your arms as you stretch after so long being in one position. You practically purr at the comforting attention the lavender-haired man gives you.

"Cut it out," the older man snaps at Shinso. "This isn’t a treat. You’ll confuse kitten." Hitoshi sighs before pulling his hand away. You resist the urge to whimper. Instead, you pull your arms over Shota’s thigh, resting your head over them and burying your face atop your paws. The raven-haired man meanly tugs your tail out of the way before he grips at one of your ass cheeks roughly. He leans down, whispering softly, "Ten, and then you’re done, kitten. I know you can do it, pet." You nod into the fluffy paws covering your fists, taking a deep breath to prepare. His hand pulls back, hanging in the air for a moment of anticipation before clapping down onto your left cheek. Your shoulders tense but otherwise you don’t move. The force was fairly light, the sting dissipating faster than you thought, but the reprieve was short-lived after the light test hit. His hand comes down firmer the second time, your asscheek reverberating with the smack and the sound resonating through the room. Lucky for you, the clap covers your tiny, unintentional squeak that slips from the force. Despite the bite blossoming through your ass, you arch your back more, giving your masters easier access to do what they wish.

Shota can't help the breathy chuckle that escapes, pleased by your easy compliance. The next series of strikes are quick and painful, the power behind them leaving your skin red and welting. His hand shifts between each cheek before his hits come down onto the back of your thighs. You can't keep the squealing and squirming down for those. Aizawa shifts you onto your back across his legs after the eighth swat before his palm slaps between your thighs. Your back arches off his legs, your head throwing back at the tingling sting spreading through your lower region. And Shota smirks at this, sadistic joy blooming in his chest as he watches you writhe and whimper in his lap. One more spank between your legs and he's done.

He admires the tears that stream down your cheeks, the way your bare chest heaves when trying to catch your breath. His eyes drift up to Hitoshi's, reveling in the unbridled amazement in his gaze. Shota knows that the younger man has never been a dom for anyone before, the closest he came were the nights the older man allowed him to top, so he also knows that his former student has never experienced the thrills that such a power over someone can bring. The pure ecstasy that taking care of a pretty pet can give. He can see it now, in the way the same perverted pleasure at the sight of your pain and humiliation seeps into his eyes. But Aizawa Shota is a merciful man. Despite the gleam in Hitoshi’s eyes, he knows that you need a little treat for taking your punishment so well.

"Toshi," he calls gruffly. You jolt at rough digits sliding through your folds, breath hitching and body shivering as they spread you out and expose you to the cool air. "Why don’t you kiss the pussy cat better?"

The lavender-haired man is all too happy to accommodate the request. He dives in without hesitation. But his rush to get his mouth on your cunt does nothing to betray how slowly his tongue works your oversensitive clit. It's torture. The way his wet muscle intimately picks you apart, circling your bundle of nerves with expert precision. The pressure makes you want to cry. It’s not enough. You need more. After being edged during their entire patrol, you need more than kitten licks and kisses. It’s almost as if the lilac-eyed man reads your thoughts, his callused digits tenderly prodding your slit. Your older dom pets back your hair as Hitoshi penetrates your entrance, his fingers tapping up into your anterior wall.

You're close—fuck—so close. Looking down at the tuffs of lavender as his head moves between your legs, you get lost in his movements. He's so focused, determined to pick you apart with only his languid tongue and deft digits. Despite his unhurried work, he's quick to pull out your pleasure with skilled movements. Just as you're about to let go, your eyes shoot open in panic. Are you supposed to ask for permission to cum? You look up at your older master, a pout taking over your features while you try to silently communicate with him. The raven-haired man smirks at the obviousness on your face, but he doesn't give you any indication of what he wants you to do. You whimper and whine, writhing in his lap as Hitoshi drags on his torturous methods. You paw at Shota's chest, mewling pathetically for his sympathy.

He chuckles, combing through your sweaty locks. "What's wrong, pet? Do you want something?" Your bottom lip wobbles. You nuzzle your head into his big palm, moving your faux paw-covered hands more insistently over his chest. "Oh, does kitten wanna cum?" You drop your pout for a relieved smile. Instead of nodding, you do your best impression of a purr and kitten-lick his palm as a sign of confirmation. He laughs at your cat-like interpretation and gives Hitoshi the go-ahead. He works faster, harder, bringing you close to the edge. "Okay, kitten, you can let go." And you do. You gasp, releasing silently, your mouth dropping into an 'O' shape. Your thighs shake uncontrollably around Hitoshi's head.

Shota gently brushes sweaty strands from your face as you breathe through the aftershocks. Your chest heaves, lips parted with your gulps of air. And your swollen, bitten lips look so dry, your mouth seeming so thirsty. So your loving masters decide you need something to drink up. Your dark-haired dom cradles you to his chest for a moment before laying you out across the mattress. Your fluffy paws rest over your chest adorably, mimicking a real kitten lying on her back. Hitoshi and Shota find it incredibly endearing. Though, you'd look even more adorable with your tummy full.

Shota nods his head to Hitoshi as he sits up on his knees beside your head, pulling himself out of his jumpsuit. He's been so hard since the moment he saw the golden pool beneath you. They both have. Achingly so—and they've been so patient while waiting to give you their milk.

Shinso follows his mentor's lead, scooting on his knees to hover over you. He tangles your leash around his fist, tugging lightly to capture your attention. "C'mon, kitty cat," he whispers. "Open up. Time for your cream." A small smile twitches your lips before they part, your tongue falling out, awaiting. Both of your masters work their fists over their cocks, their chests heaving with ragged breaths. It doesn't take long for salty spunk to spurt over your face, spraying into your mouth, along your cheeks, dripping off your chin, and tickling your nose. Once you swallow what was deposited into your mouth, you do your best to lick up the rest. It's such an odd sight—a weirdly adorable gesture in such a lewd context—and both of your doms breathlessly laugh at your effort. You wrinkle your nose, swatting with heavy paw gloves at what your tongue can't reach, and that's the moment they know.

You truly are the prettiest, most perfect, pussy cat that they could've ever asked for.
