Work Text:
“It could be worse, it could be so much worse. Really, it’s not that big of a deal. You could be living on the streets, you could be starving, you could have had to drop out of college. This? This is nothing. It’s just-... a dog-ear headband.”
Izuku finishes the pep talk to himself, looking at the headband on top of his new bed. New bed in the new bedroom of the new place he’ll live since he got evicted from his last apartment. Honestly, the place he used to live was a dump — it smelled, there was mold, the shower never got hot — and yet, he still couldn’t afford it. The beautiful, clean room he’s in right now doesn’t even deserve to be compared to his last place.
At 21 years-old, Izuku has been taking the expression ‘broke college student’ to new heights (or lows). His mom could barely afford to keep a roof over her own head, so he had to make do all on his own. And to say the struggle has been real would be an understatement. The part-time jobs he found that worked around his school schedule barely pay enough for food, and he can’t afford to take fewer classes because he’s on a scholarship that demands he takes a certain amount of classes each semester.
So when he found a job ad on craigslist that offered lodging, food, and good pay for four hours of work each day, Izuku thought it was too good to be true. But he called anyway. Beggars can’t be choosers and all of that.
And he was right, there’s a catch.
When Izuku went to talk with the person who posted the ad, he was met by the most handsome man he has ever seen. Bakugou Katsuki — a 35 years-old successful businessman in the fashion industry, editor of a famous magazine, who wears tailored suits that fit his athletic physique perfectly, and is, overall, the personification of Izuku’s wet dreams.
“You’ll be expected to dress and act like a dog.”
“Uh-” Izuku opened his mouth, but nothing came out.
“Your work will be being my pet,” the man said, without missing a beat.
“Excuse me?” he asked, completely flabbergasted.
“I live alone, my friends don’t live in town, and I don’t trust shitty extras. It can get lonely here by myself. Unfortunately, I can’t buy a dog or a cat because of severe allergies. So I’ll be hiring someone to act as a regular house pet during the hours I’m home, usually after seven until elevenish when I go to sleep.” Bakugou spoke as if he was talking about the weather.
The calm with which the businessman explained the ‘job offer’ made Izuku settle enough to ask the questions that burned in his head. If Bakugou was acting so professional, then he could do it as well.
“A-and wh-what I-I’d be e-e-expected to do?” Still, he couldn’t control his stutter.
“What pets do,” the man shrugged. “Greet me at the door, be on my feet while I cook us dinner, lay by my side to watch tv — and don’t utter a word while doing any of it.”
“A-a-and will you f-f-fu-fuck-” Izuku couldn’t even say the word, but he was understood.
“God, no.” Bakugou scrunched his face in disgust. “What kind of sicko fucks their pets?”
‘What kind of sicko hires college students as pets? ’ is what Izuku wanted to ask, but he bit his tongue. So far, though strange, it was the best job offer he had had.
“So, from seven to eleven? That’s it?”
“On weekdays, yes. On weekends, the working hours may go up to six, and I’ll leave you a schedule on the fridge. Outside these hours, you’re free to do however you want. You’ll have your own room, your own keys, and will be free to use the rest of the house when I’m not around. I have a housekeeper that comes every day while I’m at work, so you won’t have to worry about that either.”
Really, Izuku wouldn’t find anything better than this. His only other option was to take more hours in the convenience store during the night and forget about the whole ‘not having where to live’ issue since he wouldn’t be sleeping anymore. That would surely make his grades sink and he’d lose his scholarship.
“I accept it,” he said with a certainty he was far from feeling.
“Not so fast. I still need to see how you’ll perform on the job,” Bakugou said and then indicated the floor with a tilt of his head.
“Uh?” Izuku looked from Bakugou to the floor a couple of times confused before it hit him. “Oh!”
He had to show to the man how good he’d be acting like his pet.
Izuku’s stomach did a couple of flips as he got off the chair and to his knees on the fluffy grey carpet of Bakugou’s living room. The businessman seemed even bigger and more intimidating when looked from below. Those piercing red eyes followed Izuku’s moves almost bored, he clearly hadn’t impressed Bakugou yet.
With his hands and knees on the floor, Izuku scavenged his brain for any clues of how a dog acted. Izuku was so nervous he could feel his hands shaking and sweating. There was a cold dread running up and down his spine, and he felt like whimpering. He never had pets growing up, so the only thing he could think of was that when he went to his neighbor’s house, their labrador would always come begging for pats, putting his chin on Izuku’s thigh.
So that’s what he did. He crawled towards Bakugou and put his chin on the man’s knee, pulling his best 'puppy dog eyes’. When the man didn’t make any motion to pet him, Izuku stepped the acting up a notch and whimpered like he remembered the labrador did.
That finally broke Bakugou’s resolve, and the businessman began scratching the back of Izuku’s ear. It actually felt pretty good, so good that he closed his eyes and rubbed his head against Bakugou’s big hand. That made all the anxiety and stress bleed out from Izuku’s body so quickly he even felt sleepy.
Bakugou scratched his hair and carded his fingers through Izuku’s locks, making the student groan and whimper. Izuku got so into the whole thing, he doesn’t remember exactly what happened or how long they stayed that way. All that he knows is that eventually, Bakugou said, “you’re hired. I’ll expect you here on Monday.”
After Izuku left the man’s place, he didn’t second guess his decision to take the job not even once.
On Monday, Izuku dragged all his belongings inside two suitcases to the businessman’s apartment. There, he was welcomed by a sweet and helpful housekeeper that accompanied him to his new room and informed him about the basics of the place — the days she did laundry, where his towels and sheets were, how to call the building’s busboy if he had any issues. This was just as overwhelming as pretending to be a dog, Izuku never had a housekeeper before or someone he could ask for help if he had problems with his hot water.
The woman also politely didn’t say anything about the bags of stuff Bakugou left for Izuku in his new room. Certainly, it must look odd for her that a broke college student just moved into her boss’s place and is receiving gifts, but she made her best to make Izuku feel welcomed and not judged.
It didn’t take long for Izuku to get settled into his new home and be forced to deal with the gifts on top of his bed. Now, he looks at the contents of the bag with a paradoxical mix of feelings — anxiety, dread, shame, thrill.
There isn’t much. Overall, it’s quite tame. Way tamer than what showed up online when he Googled ‘pretending to be someone’s pet’. There’s a red leather collar, a headband with fluffy ears, a clearly fake tail with a clip to be attached on the waistband of his pants, and two paw-mittens -- all in fake black fur.
So far, everything Bakugou has done has been undoubtedly of non-sexual nature. Maybe the businessman really is just lonely and wants a pet. Still, picking up the headband, Izuku can’t help but feel he’s doing something naughty. He’ll dress like a dog and wait kneeled by the door for a handsome man that will boss him around the whole night.
Still, that’s his job and he has half an hour before his boss arrives home. Trying not to think about what he’s doing, Izuku puts on the tail first, just clipping it to his jeans. The headband is next, he checks on the mirror on his bathroom (he has a private bathroom!) to make sure it isn’t crooked and then looks down to the collar on top of his sink.
It’s a beautiful collar and looks very expensive. The inside is lined with soft, fake white fur and is very thick. Though it’s a little heavy, Izuku thinks he can get used to the weight. The thought of getting used to using a collar makes him nervous. Even more anxiety-inducing is the fact there’s a name engraved on a small little plaque dangling from the collar. ‘Deku’ it says — apparently, that’s his new name. Izuku’s hands tremble slightly as he wraps the leather around his throat and fastens it.
Looking at himself in the mirror again, Izuku is amazed by what he sees. He looks… lewd. His face is flushed, the collar stands out on his neck, and the little fake ears make him look like he’s one step away from getting ready in a skimpy Halloween costume. Still, that’s what Mr. Bakugou asked for, and Izuku won’t be a good pet if he starts with complaints from the get-go.
The clock tells Izuku that Mr. Bakugou will arrive in ten minutes, so he quickly grabs his mittens and the signed non-disclosure agreement that was in the bag with his ‘uniform’. He took a good while reading the agreement to make sure there wasn’t anything that could give him trouble in the future, but it was a very short contract with a pretty straightforward premise — don’t ever say anything he did for Mr. Bakugou or anything he heard about the man’s business and life or else he’d receive a fine so hefty it would get him in crippling debt for the rest of his life.
The contract is left on top of the dinner table, the mittens go on his hands, and Izuku kneels down by the door to wait for his-... boss? Owner?… Master?... For Mr. Bakugou (maybe he could think of a nickname for the man?).
As the clock ticks away, Izuku replays in his mind every little thing he researched about companion dogs. They can’t exactly tell the passage of time, so they’re always extremely happy when their owners come back. They are loving, fun, and cheerful. They think their owner is their whole world and want to be with them at all times.
Izuku can do this. It’ll be like the school plays he used to participate in when he was young. And really, standing in front of the door of this big apartment, Izuku can understand why Bakugou would feel lonely coming home to no one every night. So there’s nothing sketchy going on and it’ll be-
The sound of the lock turning breaks Izuku’s line of thought. Mr. Bakugou has arrived.
It takes a second for Izuku to change his expression from ‘slightly terrified’ back to ‘overly excited’, but he manages to do it before Mr. Bakugou looks at him.
“I’m home, Deku,” the businessman greets him and Izuku 'woofs’ back, praying it sounds alright.
***
It turns out Izuku likes being a pet.
That revelation would have shaken him to his core, but he was so comfortable laying on the couch, hugging his bunny plushie (a special gift from Kacchan), being petted on the head after eating the most delicious home cooked meal that he really couldn’t be bothered to actually shake.
Kacchan is the best pet owner ever.
(Izuku struggled with the idea of calling him ‘owner’, and ‘Mr. Bakugou’ was too impersonal for a guy that lets Izuku drop his head on his lap every night and calls him ‘his silly fluffy puppy’. So Kacchan became Deku’s naughty little secret.)
Deku is a very beloved pet. Almost every day Kacchan gets home with some sort of gift for him — pillows, blankets, toys, and treats. He gives it to Deku, rubbing behind his ear and saying that Deku is a good boy. Then he goes to cook their meals, reminding Deku that he deserves only the best and that’s why Kacchan bought steak for them.
The food is served already cut into bite sized pieces in a pretty porcelain bowl that says Deku on the side. Deku eats sitting on the floor, by Kacchan’s side and rubs his head on the man’s leg to show how much he loves the food. After that, they sit down by the couch to watch Netflix series and Deku is allowed to bring his toys with him. At bedtime, Kacchan gives one last good scratch behind Deku’s ear and says goodnight.
It’s truly great to be Deku. Never before Izuku had felt so cared for and was so spoiled. Even living with his mom, he had chores and wasn’t allowed to just stay on the couch, receiving belly rubs the whole night. The only difference between Deku and a regular dog was that Deku’s food bowl was offered to him with a spoon on the side, and the treats he receives come from a regular bakery or a Starbucks Kacchan passes by on his way home.
And it’s not only the way he treats Deku that makes Kacchan so great. No, Kacchan truly is amazing. He’s incredibly hardworking. Every day, when they’re supposed to watch TV, Kacchan still needs to check his phone and answer e-mails. Kacchan’s work is very demanding and, since he’s the editor of a magazine, close to the printing day, Kacchan needs to work the whole night to make sure everything turns out perfectly.
It’s been almost two months since Izuku came to live with Kacchan, and he’s still amazed by the hours the man pulls. Some nights, Kacchan sends Deku to bed, arguing “good boys need to sleep properly”, and then goes to his home office to keep working. Even though he has so much stuff to do, he never, never misses a night with Deku.
On the weekends, it’s just as hard for Kacchan to find time for Deku. The man is very diligent in working out, so his mornings are usually dedicated to that. And in the afternoons and nights, Kacchan calls his parents, facetimes friends, goes shopping for groceries and other errands like that. And then, if he has any time left, he goes back to work. Izuku needs to whine and rub his nose on Kacchan’s hand to convince the man to relax and spend some time with his pet.
Deku sees how diligent and dedicated Kacchan is. How the man always tries to add new designers and artists to his magazine to give them a shot, how he berates his employees for working overtime, how he’s always concerned with his mother’s health.
Sure, Kacchan has a funny way of showing that. It’s all ‘if all our magazine has the same old geezers everyone else does, I’m gonna fucking give your jobs to an intern!’, and ‘do your goddamn job during the fucking workhours instead of playing Candy Crush and having to pull all-nighters, dipshit!’, and ‘you hag better not be overworking yourself, dumb old! You’re too old for that! Go knit or some shit!’
Kacchan sounds abrasive, but Izuku knows his heart is in the right place. The idea that Kacchan would be coming home to a cold, empty apartment for nights alone if he didn’t have Deku breaks Izuku’s heart. Kacchan is too much of a good person to deserve something like that, and Izuku decided his job is to make sure Kacchan is as happy and relaxed as he can.
If dogs had opposing thumbs, Deku would be giving his Kacchan massages. Since that isn’t a possibility, he has become more assertive in affections to Kacchan. Deku makes sure to rub his face and body as much as he can, to provide some comforting touches to the man, and he has steadily increasing how much he allows himself to climb over Kacchan’s lap — before, he’d just put his head on the man’s thigh, now he puts his head on Kacchan’s chest, leaning over the man’s body.
Usually, Kacchan humors him. He teased a little the first time, “ain’t you needy tonight?”, but he didn’t push Deku away then and neither on the times that followed. However, tonight his Kacchan isn’t paying attention to him at all and Izuku doesn’t like that.
Kacchan got home late from work, ordered take out instead of making his amazing food, and now he doesn’t let go of his phone to enjoy their cuddling time on the couch. There’s a deep crease in Kacchan’s forehead that betrays how annoyed and stressed the man is. Izuku can even see how his shoulders seem more tense than usual.
Deku rubs his nose on the hand Kacchan is using to hold his phone, trying to get the man’s attention. But Kacchan just pushes him down back to the couch. So Deku pushes his whole face, almost knocking Kacchan’s phone down.
“Deku! Behave!” Kacchan yells at him. Izuku whimpers and does his best hurt expression to Kacchan, with a big pout on his lips. Kacchan sighs before talking again, “I’m sorry, but I’m busy tonight.”
Well, this won’t do. Kacchan can’t spend the whole night stressing about work. With purpose, Deku pushes the phone away from Katsuki’s hand with his nose and growls at the gadget. Kacchan just looks at the display of aggression baffled. He doesn’t even protest when Deku climbs on his lap, hugs his shoulders, and sticks his nuzzle on Katsuki’s neck.
Kacchan actually chuckles as his petulant protest. “You’re such a spoiled puppy,” he says lovingly. “Alright, I get it. I shouldn’t be working during our time together.”
Izuku huffs as if he said ‘Exactly! Now cuddle me!’, and Kacchan gets the message perfectly. The man starts petting Deku’s back and waist, and he even kisses Deku’s hair and fake ears.
“Spoiled, needy puppy…” Kacchan whispers. “What would I do without you?”
That’s a question Izuku doesn’t want to think about because he doesn’t know how he’d live without Kacchan either. After five months of working as ‘Deku’, Izuku found out he needs this as much as Bakugou. Being Deku is liberating and relaxing. It feels good to be taken care of, snuggled and spoiled. All the stress from college bleeds away the second Kacchan greets him at the end of the day and Izuku loves it.
***
Alright, maybe Izuku’s increasing physical contact with Bakugou isn’t only about offering affection to the lonely and hardworking man. Maybe it also has to deal with Izuku’s increasing sexual attraction to Kacchan.
They hug and snuggle every night — and when Deku is sent to bed, Izuku doesn’t even bother taking the collar off before sticking his hands on his pants and jerking off, dreaming about those big, soft hands all over his body. He dreams of Kacchan telling him how much of a good boy Deku is, presenting his pretty asshole and taking Kacchan’s cock so well.
Every day, Deku gets more daring in his actions, blatantly laying his head on top of Kacchan’s dick or nuzzling and licking his owner’s neck. And Kacchan lets him get away with everything.
Kacchan’s actions haven’t changed much, he still brings treats and gifts almost every day, makes their dinner, says how much he missed Deku. But sometimes, when Deku is on his lap, Izuku feels Kacchan’s lips almost kissing his neck or how the man’s petting almost becomes a groping. And Izuku loves it.
Tonight, however, Kacchan is late. Very late. Izuku actually had to eat a muffin because dinner time already has come and gone. Deku has gone through a wide array of emotions — from wondering if Kacchan is stuck at work, to being angry about being stood up, to being very worried something has happened with Kacchan. When he catches himself thinking that maybe his owner will never come to see him again, Izuku has to accept he really is acting like a pet.
It’s past midnight when Deku finally hears the keys on the door. He tip taps his mitten-clad ‘paws’ on the floor in worry and excitement. However, he’s not met with the usual happiness when Kacchan sees he’s waiting by the door. Kacchan looks almost pained when his eyes meet Izuku’s.
Deku still takes that as a sign that he needs to greet Kacchan with even more love, and starts pawing on the man’s legs and celebrating his return. Kacchan takes a deep, tired sigh before petting Deku’s head a little to calm him down.
“That’s enough. Yeah, I’m home, Deku.”
Izuku whimpers and groans, complaining about being left alone. When Kacchan looks like he’ll just trail to his room without giving Deku any attention, Izuku hugs the man’s legs and nuzzles on his thigh, making pitiful sounds.
“What are you even doing up?” Kacchan asks. “It’s already past the hour of good boys being in bed.” Cries and whimpers are the only answers the man gets. “Even pets deserve a night off…” Deku hugs Kacchan even tighter, afraid this means his owner is getting tired of him. “Did you miss me that much?”
Without meaning to, Izuku breaks the acting by nodding effusively with his face still against Katsuki’s thigh.
“You needy puppy…” Kacchan whispers lovingly and then pulls Deku to cuddle with him on the couch.
It doesn’t take any further prompting for Izuku to settle on Kacchan’s lap and nuzzle on the man’s neck. He gets a little put off when he smells a hint of alcohol on Katsuki’s breath, but it’s not overwhelming, so Izuku decides to ignore it. Deku feels too good snuggling with Kacchan, and it’s not like pets can grill their owners about where they have been — or with whom.
That doesn’t stop Izuku from trying to smell if there’s anyone else’s perfume on Kacchan. He shoves his face on the man’s chest, trying to sniff any scent that isn’t Kacchan’s natural smell or his cologne. He does the same with Kacchan’s collar and neck, going all the way to under Kacchan’s ear.
“Sorry, sorry,” Kacchan chuckles, amused by Deku’s weird behavior. “I won’t stay out so late again…”
Izuku is pleased to not smell anyone else on his Kacchan — and he’s even more pleased when he feels Kacchan erection probing his butt. Instantly, he feels the need to see and feel more of Kacchan.
Since Kacchan seems to enjoy being sniffled, Deku keeps nuzzling and smelling in a downwards path over Kacchan’s chest and abs until he reaches the man’s groin.
“Deku?”
He has to scootch back on the couch, in all fours like the pet he is. Izuku doesn’t see which expression Kacchan is making, but he hears the man’s breath hitching when Izuku nuzzles on his very hard cock.
Deku loves how hard and warm Kacchan feels against his cheek and nose. He really wants to know how Kacchan smells and tastes like. Without second-guessing, he bites the top of Kacchan’s pants to pop the button and pulls down the zipper with his teeth.
“Shit, Deku… You don’t-”
Whatever objection Kacchan had, died on his lips when Izuku licks his dick over the thin cotton of his black boxers. Deku likes how Kacchan smells and likes even more the little moan he hears coming from the man.
The next step is trying to pull Kacchan’s underwear off. This proves to be way harder than the pants, though. Deku bites the elastic and pulls down, releasing Kacchan’s angry red cock, but he can’t make the clothing pass his balls.
Deciding that’s enough for now, Izuku latches on to the head and drinks the pearly drops of precum that Kacchan offers to him. “De-Deku-!” Kacchan cries, and his hand tangles on Deku’s hair.
But Kacchan doesn’t pull him out. His fingers twist Deku’s hair for a second, and then he starts petting his dog. “Such a good fucking puppy… Shit…”
Izuku loves hearing the praise, he loves being Kacchan’s good boy, and that gets him to suck his owner’s dick even harder. Deku lets his tongue play with the underside of the cock and bobs his head up and down. When he gets to the tip, Izuku gives a harder suck or opens his mouth to let Kacchan see the fat head of his cock on Deku’s pink tongue.
Looking up, Izuku can see that Kacchan follows every one of his movements with hazy eyes. Kacchan’s face is flushed, and sweet little moans spill out of his lips as he enjoys Deku’s blowjob. Izuku bobs his head up and down sloppily as drool starts dripping down Kacchan's dick. Seeing Kacchan’s lustful expression for him makes Izuku’s blood run hot like lava. He can feel his own dick straining painfully in his pants, begging for release.
Kacchan’s hand goes back to petting him and the man offers more praise. “Fucking good boy… You’re so good to me… My sweet Deku, my perfect little pet…” That gets Izuku so hot and needy that he lowers his hips until he’s dry humping the couch. Pitiful little moans and whimpers are muffled by Katsuki’s cock as the fabrics rub on Deku’s dick in a painful and delicious way.
“Deku?” Kacchan calls him and gently pulls Izuku away from his dick by the collar. Izuku fights back, but Kacchan manages to maneuver him back to his lap while saying sweet little things. “That’s enough, puppy, that’s enough… You did so well. And what do we have here?” Kacchan palms Izuku’s erection, making him whimper more. “My poor puppy… This must be hurting, right?” Izuku nods and makes pitiful soft noises while trying to rub his crotch against Kacchan’s hand. “Let me take care of my pet now…”
And then Katsuki pulls him to a deep kiss. It takes no probing for their tongues to meet hungrily. Kacchan devours Deku as if he’s starving and Izuku revels in it. He hugs Kacchan’s neck desperately and, as if Izuku doesn’t weigh any more than a small lap dog, Katsuki hoists him up in a princess carry and takes him to his bedroom.
The moment Izuku’s back hits the mattress, he’s already waving his mitten-clad hands, trying to bring Kacchan closer to him again. But Katsuki disentangles himself from him. “Calm down, puppy,” he chuckles. “I’ll be there in a second.”
Izuku whines, but stops quickly when he sees why Kacchan pulled away. The man is stripping off his clothes, showing his perfectly sculptured body to Izuku. Kacchan is really cut and defined, has big pecs and thick arms, and his cock is still glistening from Izuku’s saliva. A pleased growl rumbles through Deku’s chest.
“Now it’s your turn, puppy,” Kacchan whispers sinfully to him as he climbs the bed on his knees until he’s hovering on top of Izuku. “Give me your paw.”
With Kacchan sitting on top of his thighs, Izuku extends his arms towards the man. Kacchan takes one of Deku’s paws and takes the paw-mitten off before kissing Izuku’s wrist and palm. On the second hand, Kacchan takes a moment to suck on one of Izuku’s fingers, making him whimper.
“Good boy,” Kacchan whispers. “Now let’s get this off.” And he starts pulling Izuku’s t-shirt up.
When the t-shirt hits the floor, Kacchan focuses on Deku’s shorts. The man doesn’t seem to stop to think as he pulls off the shorts and the boxers in one go. Izuku is left naked on his bed — except for the thick red collar, the dog-ear headband, and his dripping erection.
“Ain’t you a sight, puppy?” Kacchan runs a hand on Izuku’s thigh. “The most beautiful pet I’ve ever seen.”
Deku whimpers and spreads his legs. Kacchan smirks at him, “Do you want something, puppy?” Izuku nods and bucks his hips. “This?” Kacchan fondles his balls. It’s good, but it isn’t what Izuku wants so he shakes his head and spreads his legs wider. “Does my naughty puppy wants me to play here?”
One of Kacchan’s fingers rubs slowly around his rim, teasing him. Deku nods and whines desperately. “Such a dirty, naughty puppy… I thought my Deku was a good boy.”
No! Deku is a good boy! The best boy! Kacchan always says so! Just because he wants Kacchan’s cock deep inside him, it doesn’t mean he isn’t a good boy anymore! Deku just wants to show how much he loves his Kacchan, and receive all the care and affection Kacchan has for him.
“Shh, calm down,” Kacchan says, chuckling. “I was just joking. My Deku is the best boy and deserves all the treats and pets, right?” Izuku nods desperately. “Like this treat?”
One lubed up finger breaches in Izuku’s puckered hole, and he moans in pleasure. He hasn’t seen Kacchan grab the lube, but he really won’t argue because that’s exactly what he wanted. Kacchan’s other hand rubs his inner thigh, teasing his balls. Izuku loves the combination of sensations Kacchan is offering him, and pleased noises come from his lips.
“You really are a good boy, opening up for me like this…” Kacchan’s voice is lewd and raspy. “I bet you can take two fingers already…”
Izuku bucks his hips against Kacchan’s fingers to indicate that yes, he’s the best boy and can take as many fingers as Kacchan wants to give him. He loves the feeling of being stretched; Kacchan’s fingers are so thick inside him, much better than his own.
“Good puppy,” Kacchan coos at him. “Let’s see if I can make you bark for me…”
Kacchan sticks his fingers deeper and probes inside until he finds Deku’s prostate. Izuku jumps in the bed and gasps loudly at the harsh poke in his prostate, Katsuki chuckles and gently rubs the little ball of nerves after that. “Found it,” Kacchan teases, smirking.
Crying and whimpering, Izuku works his hips against Kacchan’s fingers. It’s absolutely maddening and Izuku can probably cum just like that, completely untouched on Kacchan’s fingers. That thought takes Izuku out of his haze of pleasure, because he doesn’t want things to end so soon.
He whimpers louder and makes grabby hands towards Kacchan, but the man looks very pleased watching Izuku unravel for him. “Good puppy, just relax and enjoy…” But Izuku refuses to this end this way. He wiggles and squirms, pulling away from Kacchan. “Deku?” Katsuki asks worried, giving Izuku some space.
The moment Kacchan isn’t crowding him anymore, Izuku flips in bed and raises his hip, presenting his ass in a way he’s sure Kacchan will understand the message. He even shakes his booty a little when Kacchan takes too long to get moving.
“Fuck…” Kacchan murmurs under his breath, his big hand feeling up Izuku’s ass. “Damn, puppy… You want me to mount you?” Izuku whines and shakes his ass again. “And here I was thinking I had a boy, but I have a cute little bitch…” Kacchan spreads Deku’s ass cheeks to look at the blinking hole. “Are you ready for this, my good bitch?”
Izuku feels Kacchan teasingly rubbing his cock on his hole, so he whines loudly and presses back. Katsuki doesn’t need any more prompting, he aligns his dick to Deku’s hole and thrusts in as slowly as he can while a string of praises and profanities spill from his lips.
“Shit- Deku… Such a good boy, a good bitch… You’re going to take my cock all the way… I’m going to fill you so good, I’m going to breed you… Fuck- So tight, puppy… Your little ass is so tight…”
Each little praise goes straight to Izuku’s cock. He loves being Kacchan’s good boy, he loves being a good bitch taking Kacchan’s dick. And what a dick — it feels so incredibly hot and big inside him, touches his prostate in the most delicious way. It’s so fucking good and he wants more, he wants so much more.
As if reading his thoughts, Kacchan picks up his pace until he’s slamming hard and fast against Deku’s ass. Each time Kacchan thrusts in, his cock hits Izuku’s prostate hard and has him seeing stars. Never before Izuku has been fucked so good; any former boyfriend or fling pales in comparison to the raw power Kacchan has fucking him.
The slapping sound of their skins echoes loudly through the room, but it doesn’t drown the loud moans and whimpers coming from Izuku or the grunts from Katsuki. Deku loves feeling Kacchan’s praise on his body — it’s not just words, the way Kacchan grabs tightly on his hips and fucks into him with desperate abandon is praise on itself. The tighter Kacchan squeezes him and harder he thrusts into him, the closer Izuku gets to cumming.
And he’s so goddamn close. Deku can feel his orgasm just a breath away and he doesn’t know if he wants to reach for it or to stall so he can enjoy the sex for longer. The decision is made by Kacchan, though. Katsuki falls on top of him and hugs Izuku against his chest. For a second, it’s hard for Izuku to not fall on the bed with the weight of the big man on his back, and as soon as he gets his balance back, Kacchan starts jerking him off.
“Cum for me, puppy,” Kacchan orders him in a broken voice. “Cum for me, and I’ll fill you up. Gonna- Ahn!~ Gonna breed you, my little bitch. Want me to fill you with my cum? So be a good boy and cum.”
As if on command, Izuku’s orgasm rips through his body, making him shake violently. His mind completely blanks out and he barely registers that a couple of aborted thrusts later, Kacchan cums inside him. Deku loses the fight to keep himself from collapsing and just relaxes, getting comfortable on Kacchan’s bed.
Kacchan’s warm body falls by his side and he keeps hugging Deku for a good while. Sleep is almost taking Izuku in its arms when he feels the bed dipping and Katsuki getting off. Deku doesn’t have time to find the strength to look for Kacchan before he was back, though. And the feeling of a warm cloth cleaning him explains what Kacchan was doing.
Caring and thoughtful as always, Kacchan cleans him all up, takes off the red collar and the headband, gets rid of the dirty sheet from beneath Izuku, and covers him with a new clean sheet and a light blanket. Deku’s barely conscious through it all, but the moment Kacchan lies beside him and pulls him to his chest, Izuku snuggles against the man.
“Good night, puppy” is the last thing Izuku hears before sleeping.

The next morning, Izuku holds on to sleep for as long as he can. He’s too comfortable, and he doesn’t want to face the day yet. Honestly, he hasn’t felt this good in so long — his pillow is softer, there’s a nice smell, and he’s hugging someone warm-
The realization that there’s someone in bed with him makes Izuku’s eyes snap open, and his whole conscious quickstarts startled.
“Good morning, Izuku.” Kacchan’s voice sounds very amused, if still raspy from sleep.
Deku doesn’t know what to do. He had sex with his boss yesterday! And now he was rubbing his face on his boss’s very sexy and very naked chest. What should he do? Should he say anything? Apologize for starting things last night? But he isn’t allowed to talk!
“I’m pretty sure we’re over that by now. First, because you’re off the clock, so you’re not my pet now. And second-” Katsuki cups his face and forces Izuku to look into his eyes. “Because you’re a mumbler and have been talking since I hired you.”
Oh fuck. Izuku’s eyes get huge in surprise as he processes that information. He’s been talking? To Kacchan? And he hasn’t been fired?
Kacchan chuckles, “Why would I fire you? It was the cutest shit ever to hear my beautiful puppy mumble about how much he loves my petting, my food, and his little stuffed bunny.” Kacchan gives a soft peck on Deku’s lips and continues sinfully, “and it was the sexiest thing ever to hear you mumbling about how good my cock feels.”
“It- it feels very good.” Izuku’s mouth offers without his brain’s permission.
“Well then… I guess I should give it to you again,” Kacchan whispers, kissing his jaw as his hands start wandering over Izuku’s body. “I’ve been going crazy, dreaming about fucking you for months… I tried to stay away, but I just couldn’t…”
However, Izuku has too many doubts in his mind to get in the mood yet. “Wa-wait! What does that mean? Am I not fired?”
“I don’t know,” Katsuki answers earnestly. “Do you want to keep being my pet?”
“I-... I really love being your pet… So I can just put on my collar and-”
“I don’t want you on your collar now.” Kacchan looks deep into his eyes. “I like spoiling you as my puppy, but I don’t want that to be all of our relationship. I want to talk to you and hear your voice, not just through mumblings.”
“I- I'd like that too…” Izuku blushes and looks away.
“Perfect, then from now on, you’re my boyfriend first.” A small kiss seals their deal. “And my pet when we feel in the mood… What do you think?”
Izuku smiles brightly as him. “It sounds perfect, Kacchan.”
Katsuki lays on top of him with a predatory smile. “Now, let me make you scream this stupid nickname you gave me, Deku.”
