The chill of the cold night air hits your sweaty face and palms creating a slight tinge of pain from the contrast between the temperature of the night and your body. You have been running away from the robbery in progress after the police arrived to chase after the villain who caused it. Your calves burn and your feet feel like glass from how long you've been running and chasing after him. You dip, dodge, and jump over all the obstacles in your way and as he threw something behind him, you just barely ducked enough for it to only graze your palms as you tossed it out of the way, a little scrape left in the wake.

"Will you fucking stop already?!" You scream out to the villain dressed in an all-black outfit with a purple short cape swirled with various patterns that seem reminiscent of various animal footprints on it.

"You seem too slow hero, might need some help with that!" The guy yells back before slapping a random shape on the back of his cape and using his fist to throw an orb of light at you but you quickly sidestep out of the way just in time.

Taking the chance after he stumbled from throwing it at you, you open your palm wide and fire three balls of fire at the villain in front of you. They all land perfectly into his side and he doubles over and falls over his own two feet while running. He skids along the pavement and takes out a lamppost in the process but he ultimately comes to a stop and lays still while breathing shallow breaths.

"Hah, I, hah I got you, villain." You say panting and out of breath. "Damn I need to work on my stamina." You say mostly to yourself.

You bend down and flip the villain over onto his back before grabbing a tight pair of handcuffs from your utility belt and quickly clasping his wrists with them and hiking him onto his two feet.

"Cherrybomb did you apprehend the suspect?" Your partner Shinso asks you over your earpeice.

You reach your free hand up and tap the button before replying.

"Yeah just now. Head back to the office and I'll meet you there after I call a cruiser to take him to the station."

"Heard, stay safe."

You confirm with Shinso and tighten your grip on the suspect before notifying the police of your new location and wait for them to arrive.

Only a few minutes pass before the cruisers show up and they grab the villain from your arms, and right as you're about to pull away, the suspect breaks free from one of the officers grasp and walks darts towards you and grabs your wrist in an attempt to attack you while you were distracted talking to civilians. You turn around to attack him back but the officer already managed to grab him before another brawl could start and slapped him with another pair of cuffs. Unbeknownst to any of you, he was able to slap a paw print on the back of his cape and touch you with it when he grabbed your wrist. The villain gets shoved headfirst into the back of the quirk and armor-proof van before the doors shut loudly and they drive away.

"Cherrybomb! Cherrybomb yet another excellent takedown of a villain and you stopped the bank robbery with no casualties, how did you do it?" A reporter asks while the cameraman points the camera towards you and you confidently reply how you normally always do.

"Meow!"

You freeze in confusion, the reporter freezes in confusion, and so does the crowd that has gathered around you all.

"I'm sorry, meow?"

You go to speak again but before you can, you feel a tingle in your hands and you look down to see that your fingertips are slowly morphing into sharp feline-like claws.

You roll your eyes and mutter a "fuck" out loud but to everyone else it just sounds like another meow. Before you could be bombarded with more questions, you take off running down the road and into the secret alleyway you knew one on would find you at. You had found this alleyway months ago after you had gotten beat up pretty bad in a brawl with the LOV and managed to stay secluded all night until you told Shinso your coordinates to find you.

When you duck under the torn hole in the chainlink fence to get to the hiding spot, you brace yourself up against the back of the brick building and look down at your hands to see they've morphed into paws as well as your feet. When you look back up at the brick, you also notice you've gotten incredibly smaller than you remember. It wasn't until you turn around and see a big fluffy tail attached to your butt that you realize what that villain's quirk was; Beastmorph. He turned you into a cat.

"You have got to be fucking kidding me." You say to yourself in your head. You try and find a way to break out of your transformation by running headfirst into the brick wall but all you get out of it is a nasty headache, you can't seem to break out of it by force. You shake your head and droop your ears at the pain and lick your paw and rub your ear to ease the pain.

You saunter around the damp alleyway and see your reflection in a puddle next to a garbage bin and stare into it. You see a slight scar from where you headbutted yourself and notice your very fluffy y/h/c fur blowing in the slight breeze and getting damp from the rain that started to roll in overhead. Staring into your feline eyes in the puddle, you don't even notice the hulking figure walk up behind you and scoop you up. You yelp at the sudden loss of connection of concrete on your paws but feel relaxed in the strong arms of however picked you up, even more so when you feel two soft fingertips rub behind your ears.

"Hey, kitty kitty what are you doing out here?" You look up and instantly recognize the purple hair of who grabbed you.

If a cat could look surprised, you were surely embodying it.

"Where the hell is y/n, she's not at the office and she's not here. God, I hope she's alright."

The rain starts to fall harder and you yelp at the sudden feeling of your soaked fur. You accidentally sink your claws into Shinso's arm while hiking your butt up to try and shake off the wetness and you hear him slightly gasp at the pain.

"Hey hey, kitty it's okay. Come on let me take you home and get out of this rain."

Before you can try and jump out of his arms, he grips you tightly and covers you under his cape while taking off his mask and doing his best to walk under awnings to keep you both from getting even wetter.

You recognize all the turns and roads Shinso takes to get back to his house as you've been there multiple times. It doesn't take him very long to make it back and when he enters his house he shuts the door behind him and places you on his comfy couch. You drop with a slight bounce before he sets his things down on the counter and locks the door behind him.

"Make yourself at home kitty, I'll keep you here tonight and figure out what to do with you tomorrow."

He leans over the back of the couch and starts petting your head and back, and while it feels awkward, it also brings on a strange warmth that you haven't felt before. You smile the best a cat can and you feel your tail swish back and forth. Shinso chuckles before scratching a certain place on your lower back, right above your tail, and your eyes practically bulge out of your head at the extremely weird pleasure it brings on. You are torn between trying to move away or enduring the weird feeling, and it wasn't until you feel a rumble in your chest that you realize you're purring so you decide to hold out and enjoy the scratches.

"Good kitty."

His words strike a chord in your head and you roll your eyes and shiver from the unknown feeling inside of you. Shinso smiles once more before stopping and turns into the kitchen and grabbing a bowl from a cabinet.

You whine at the loss of contact and hop up on the back of the couch and stare at him while cocking your ears behind your head and staring at him.

"Sorry girl, I don't have any cat food but I'll pick some up tomorrow after work."

He says to you as he places a glass bowl of water down on the floor next to a wall. You hop off the couch and walk down next to it, as much as you highly don't want to drink from a bowl like some animal, you are pretty parched from the earlier fight so you lap it up while you can. When you finish slurping it up, you look up and see that Shinso has disappeared and you go to look around his house for him before you see his bedroom door open. You strut over into it and your eyes go wide at the sight in front of you.

His shirt is off of his body and he's walking around in just his boxers as he takes his dirty uniform and tosses it into the laundry basket. His slight muscle definition makes your mouth water when he turns around and you catch a good look at his back. This is the first time you've seen Shinso completely shirtless within the few years of working at the agency together, which is surprising considering the countless amount of times you two have had to patch each other up, he's even seen you completely shirtless besides your breasts as you've always covered them. You walk further into the room and he turns around and you see an array of patchwork tattoos scattering along his arms and a few on his chest. A few of these you've seen before, but you also notice many new ones which make your mouth water even more that your tongue lulls out the side of it.

You are quickly blushed when you see that he's about to pull his boxers down, and with the fear of perversion coming over you, you quickly pounce out of the room and back onto the couch. You shake the thoughts from your head until you hear Shinso's voice speaking to you from two places at once; your head and the adjacent room.

"Y/n, where in the fuck are you. You weren't at the office or your alleyway. Are you alive?" He asks you over the earpiece, which is weirdly enough still attached to you in your cat form. You go to speak but remember how it came out as a meow last time, but you are surprised by the actual words from your mouth.

"Yes I'm okay, I had a uhm, accident and I'm waiting for it to subside." You speak in your actual voice from underneath the couch where you moved to in fear that Shinso would hear or find you.

"What? What accident?"

"A mishap with the villain's quirk I think. I'll be okay I'm just waiting for it to disappear. "

"I-okay then. I'll see you at work tomorrow." He says more of a question than a statement.

"If I'm better by then, sure."

"Okay, goodnight y/n."

"Night Toshi."

You get out from under the couch and trample into his bedroom after checking if the coast is clear first. You see that the en suite bathroom is in use by him when you hear the shower start and him grumbling as he steps inside. You leap onto his bed and stare at yourself into the mirror attached to his side wall that faces the bed. You stare into your eyes and notice that your pupils are no longer stretched like a cat's eyes are and that they've reverted back to your normal eye color and shape. With your voice back and your eyes reverting back your normal body should return by tomorrow. Oh shit, your normal body will return tomorrow. How can you leave without Shinso catching you?

You're caught off guard when you hear the bathroom door open and steam billowing out of it and a very stark naked and dripping wet Shinso walk out of it.

"Me-ow" You gulp to yourself out loud when you see him walk over to the bed while wiping his damp hair with the tan towel around his broad shoulders. You can't help but trace his body down and notice the purple patch of hair above his pelvis and the happy trail connected to it, it fits perfectly against the shallow v-line under his hips.

You feel a shiver ripple through your body and your tail swish back and forth slowly while you take in the sight of the juicy man in front of you. You don't even hop off the bed when he sits down on it next to you and begins petting you. A very loud purr erupts from you and you nudge your head against his hands before he pulls away and scoots you a little bit away so he can get under the comforter.

He turns on his side and flicks off the bedroom light before huffing and puffing while rolling back over onto his back. He slides his fingers through his hair and tugs on it slightly before sliding his hands down his face and dropping them on top of the blanket. He turns back over to you and smiles as he pets your head.

"I hope y/n is okay kitty. You'd like her if you met her, she's beautiful and sweet to every animal she meets. She has one hell of a mouth on her to just about everyone else though." Shinso chuckles to himself at the last thought and you can't help but feel taken off guard at the unknown compliment he gave you. "What I wouldn't do to just make her shut up sometimes."

You quietly gulp to yourself when you feel him tense up while he's petting you before he stops entirely and sits up in his bed and scoots you off of it and towards the door but never shutting it. He whispers something that you don't quite hear before walking back towards his bed and sitting up against the headboard.

You can't help your curiosity as you tip-toe your toe beans into his room and tilt your head around the edge of his dresser and catch sight of what he was doing.

He groans as he rests his head back against the headboard with his eyes shut and his one hand tracing his nipples while the other strokes his cock to get it hard while quietly muttering your name. He's sitting above the comforter and you feel impressed at the endowment of him, you'd never think he'd be that big. You lick your lip and accidentally catch your tongue on your fang before shaking your head and walking closer to the bed to hear and see him better, your morals are entirely out of the window as you don't care how wrong it is to watch your coworker touch himself to the thought of you.

"Fuck." He moans out as he takes his thumb and spreads his precum around his cock while rubbing his nipple with his thumb. He pumps himself while squeezing the base of his cock and you see him shiver at the feeling with taking his free hand and dropping it onto the comforter and gripping the sheets until his knuckles turn white.

"Y/n, just like that, fuck." He says shutting his eyes tightly while envisioning you riding his cock all nice and tight.

You've somehow found your way into his closet and are staring at him through the doorframe of it. Also at this point, you haven't noticed that your hands and feet have reverted back to normal, along with everything else about you. Well, besides the fact that you still have your tail and cat ears. You still don't realize it when you take your hand and touch yourself along with him and rolling your eyes backward when you feel your fingers rub your clit in pace with his pumps.

Moving your hand in time with Shinso's, you stick your fingers into your wet cunt and you moan out his name at the feeling of it, but you quickly clasp a hand over your mouth and put your back against the closet door hoping he didn't notice.

At the sound of your moan, Shinso shoots his eyes open and his head pops up and he stops touching himself while looking around the room. He quietly turns on the end table light and his eyes squint at something in his bedroom when he sees your bare foot poking out of the side of his closet. He gets up from his bed very quietly and walks over to the door and slaps his hand alongside the doorframe making you scream before slamming the oak door right into his face.

Confusion, arousal, and aggravation fall over Shinso's body at the sight he saw before him. He saw you standing stark naked in his closet, with your fingers deep in your cunt, with a pair of cat ears and a tail matching the cat he took home earlier today. He scans the room and takes in the fact that the cat is nowhere to be seen and he smirks as his knuckles come up to the closet door to lightly rap against the wood.

"Oh y/n?"

Silence, which is hard considering you're still touching yourself while also biting your hand and clamping your eyes shut as you try and hold back your lewd noises.

"I know it's you."

It's no use, you can't help but let your noises and words slip.

"Fuck."

A flip switches inside of your body and you're frozen, waiting for some unseen instructions to guide you. Shinso smirks to himself and you curse at yourself in your head as you forgot about his quirk.

"Open the door and come out."

His husky tone sends shivers down your body as you do exactly what he says. You open the door and see him standing there with his arm above your head resting against the closet doorframe. You step in front of him and his free hand comes up to grip your chin and stare into his eyes and the contact breaks you out of your trance.

"Hi, kitten." He says hungrily.

"H-hi Toshi." You gulp at getting caught and now fully realize you're, mostly, back to normal.

"So this is the mishap? Didn't think to tell me about it?"

"I'm sorry, I didn't even know what happened. The villain must've blindsided me with his quirk and I got turned into a cat."

You don't know why you feel like you have to explain yourself to him, but you're utterly at his mercy and it isn't at all due to his quirk. You're entirely yourself right now.

"Hm, how unfortunate. It's even more unfortunate about what I'm going to do to you for deceiving me."

You gulp.

"What, uhm, how did I deceive you?"

"You acted like such a good kitten when in reality I know you're nothing but a slut wanting to be fucked by me. Dirty fucking girl."

"Toshi, no I can't, we can't."

That trance is back that you felt before.

"Shut up."

You do.

His hand drops from your chin and he stands confident and tall above you.

"Get your ass on the bed and wait for me."

Your feet mindlessly walk on their own. You squat onto his bed and turn towards him while sitting on your thighs and letting them plump out around you. Your palms rest against your thighs and your tail swishes back and forth while you wait for him.

"Good girl."

You're still locked in the trance but you feel the pool starting to drip from your cunt at his words and actions. You watch as he stalks over to you, like the way a cat does to a mouse, but in this case, you're the ladder in this situation.

You gulp when you feel his fingers trace your bare chest before stopping on your breast and giving one a good squeeze. You moan while getting knocked from your trance and he takes that as an invitation to continue. He releases your breast and immediately grips the back of your neck with force before bending down and kissing you sloppily and passionately at the same time. You moan even more and you feel him smirk into you as his free hand traces down your breasts, flicking your nipple, then trailing it down to your sopping core. You whimper when you feel his finger ghost over your warm folds and then he slides his finger in between them to catch all the juices coming from you.

"Well look at this, my kitten is all nice and wet for me already. I knew you were a slut y/n."

You roll your eyes at the words and it was a big mistake on your part when you feel a slap against your breast and you gasp and look up to the lavender eyes drilling into yours.

"Don't be a fucking brat with me." He dips two fingers between your folds again and as you whimper, he takes that chance to stick them into your mouth and down your throat. "Taste yourself and shut up." His hand grips the back of your neck tighter and bends it back as his two fingers get shoved down your throat and you gag on his fingers. Tears prick your eyes at the feeling and you feel yourself grow wetter and wetter at the force and words he's using on you and you just want more.

He pulls away from you and you both smirk at the long strands of saliva that trail from his fingers and your mouth and he licks it off his own fingers before releasing your neck and pushing you down onto the bed.

"Do you taste good kitten? Spread your legs for me and let your owner taste."

"Ho, fuck Toshi."

You say as he pushes you back and bites your thigh, but he shoots up and tuts at you.

"It's master now."

Your eyes roll back in pleasure as he spreads your legs and kisses your folds and you let bliss take you.

"Ye-yes master." You bite on your finger from the pleasure and use your other hand to twist into Shinso's locks. He groans into your pussy when he feels you tug on his hair and as you buck your hips into his mouth, he wraps an arm around your thigh and rests his hand flat against your pelvis, and uses his other hand to rub up and down your chest and squeezes your breasts making you shiver and shake.

His tongue is that of a god, he's eating you out like no other has done before and you don't want him to ever stop. His tongue speaks passion into your core as he twists your nipple in between his thumb and forefinger and gives it a sharp tug which makes your chest rise and gasps of pleasure drip from your mouth. You feel him smirk into your pussy and your thighs clamp around his head when he nibbles your clit and he smiles even more with the feeling of it happening.

Within minutes you're seeing stars as he plunges the hand he was using on your breasts into your warm cunt while he uses the hand on your pelvis to rub your clit. He sees you trying to resist the urge to cum and he feels himself grow harder which only causes a mix of pleasure and pain to score through him. He needs contact but he only wants the focus on you, he only wants his precious kitten to feel good tonight.

"Fuck master, can I cum? Can I please cum baby?" You beg him as you knot his hair tighter with both hands now.

"Go ahead kitten, cum on my face for me."

He plunges into you and rubs harder at the same pace and dips his mouth back to your pussy before you release onto his face so much that it drips down his chin. He pumps you a few more times before pulling his fingers out of you and smiling down at you panting and wiping sweat from your brow.

You're caught off guard when his dominant persona is dropped as he bends down and kisses you on the forehead and lips before checking in on you.

"Are you okay baby? Can you keep going or can you stop?" He asks so sweetly and innocently.

You run a hand through his hair softly and swipe your thumb against his lips before bending up and kissing him, tasting a mix of himself and your fresh juices which make you want round 2 even more now.

"Please master, I want you to fuck your little kitten-like no one else has before." You whisper seductively into his ear before nibbling on it and licking his neck and falling back down onto the bed.

"Holy fuck." You managed to catch him off guard this time. He gets back into the persona, now even more eager before gripping your hips so tight you know for a fact you'll bruise, and flipping you over with a hard bounce back on the bed and you gasp when you feel him hike your ass into the air.

"Look at your precious cunt, so beautiful and wet for me." He smacks your ass and you yelp out in pleasure before he scissors inside of you with his fingers, stretching you out and pulling away and to his side drawer.

"No master, let kitten feel you. Please?" You ask him while reaching back to grip his wrist.

"You want me to fill you nice and full with my cum kitten? Dirty fucking girl."

He spits into his hand and pumps himself a couple of times before lining himself up with your hole. He grabs both of your ass cheeks and rubs them gingerly with his thumbs before spreading your lips and entering your pussy slowly, getting you used to him.

"Hah, fuck Toshi- Master, I don't care, oh fuck." You shake out the words as you feel him bottom out inside of you and you don't even fathom how you managed to take him so well. Your toes are already clenching when he pulls out and slides back in just as slow as he did before.

"Fuck yeah kitten, I'm gonna fill you so good and full with my cum. Can't wait to have my fucking child can you?"

His head falls backward as he starts to pick up the pace inside of you and groans loudly when he feels you squeeze around him. The villain's quirk has entirely disappeared by now but neither of you has noticed and neither of you cares from the absolute ecstasy you both are receiving from the other.

His cock is slamming back and forth into you at an incredible pace. For every handful of hard pumps into you, it's followed by a slow and teasing pound that hits your spot perfectly every time. You don't know how long you've been going at this, minutes, hours, doesn't matter, you don't want it to ever stop. Your pussy clenches around his cock like it was perfectly molded to be there. Shinso slaps your ass with so much force it leaves a gorgeous dark handprint afterward. You both moan out a "fuck" from the way it made your pussy jump and Shinso picks up his pace inside of you.

"I-I'm about to cum Toshi, fill me up nicely with your cum baby."

You barely manage to get out as he slams harder into you, hitting your g-spot with precision. He smirks and you hear it in his moans. He slows down slightly before bending down and slowly tracing his hands along your sides, squeezing your breasts, gripping your throat, and bringing you back up with him so that your back is against his chest. This new position has you absolutely in pure bliss. You see your entire life flash before your eyes when he grips your throat tightly and bites the side of your neck while his other hand rests against your hip bone and rubs circles into it.

"You're going to be such a good mother, baby." He bites your neck harder. "You're taking my cock so nice, and I'm about to fill you to the brim with my cum. Can't wait to see your stomach bulge with my kid." With that last sentence, his hand moves from your hip to your stomach and he pushes on it, especially in the place where he feels himself slightly bulge your stomach.

"Fuck, can't wait to be a daddy huh? Fill me the fuck up already." You quip back to him, gathering confidence when you feel his thrusts become sloppier and you know he's about to cum with you.

"Watch your tone." He says into your ear while gripping your throat even tighter, cutting your breath off a little before kissing you on the lips and biting your lip while letting go of your throat to let you breathe.

As soon as he bites into your shoulder, you both moan out at the same time when you each release with one another. Your cum mixes with his as he shoots his seed deep inside your cunt. You feel it pulse inside you and your tongue lolls out at the feeling. Shinso keeps himself inside of you until your cunt takes every last drop and when he's content with how much he filled you, he slowly pulls out and watches the cum drip from you before using his fingers to push it back in.

"Keep it in there while I go get a towel to clean us up."

You whimper out a confirmation and as soon as Shinso steps out, you fall back onto the bed and giggle to yourself at the absolutely insane situation you just had. You'd never imagine that you'd fuck your coworker but here you are. You don't move when Shinso comes back and kisses you on the forehead and lips while he wipes in between your legs and anywhere else you may feel hot or sticky. You grab him before he moves away and you bring his forehead down to yours and give him a sweet kiss on his lips and you both smile at each other.

Shinso tosses the towel into the basket and slides under the covers next to you. He lifts his arm up to have you slide up next to him and he breathes out a content sigh.

"So...have you always wanted to fuck a cat?" You ask trying to break the ice.

Shinso laughs and gets beat red at your comment and turns his head to face you.

"No, no I haven't. To be clear, I didn't want to fuck a cat, I just wanted to fuck you."

"You surely did." You pause before your next thought. "Did you mean what you said when you were talking to the uh, well, cat-me?"

"All of it, yeah."

"Oh, cool, cool."

You stop for a minute and try and get comfortable but there's still an unease in the air.

"Look, if this was just a horny-sex haze type of thing for you I get it. I won't mention it again." You say while sitting up to talk to him, as your breasts fall from the sheets, Shinso can't help but stare. You giggle and snap your fingers in front of his face to get him to look at you.

"No y/n, it's not a one-time thing for me. I don't know what I feel for you but I know it's not a one-night stand type of feeling."

"Oh..good, cause I'm pretty sure I fell in love with your dick."

Shinso bursts out into a fit of laughter before pulling you down on top of him and kissing you intensely and having you straddle him.
