The Double Life of Kannonzaka Dog-ppo

Summary:

Doppo, a werewolf who can shift at will into the form of a dog, just wants to relax after work. Sure, he doesn't expect to be taken home by one of the Buster Bros nor adopted as the family pet, but there's no harm in that.

If he can behave himself.

Notes:

This is a birthday fic for my friend, Roo. I love you so much and I hope you enjoy this!! ^w^

[Not beta'd so sorry for any mistakes.]

(See the end of the work for more notes.)

Work Text:

Doppo needed a break.

 

He needed a vacation, really, but if he did that, Doppo knew his boss would give him Hell, he knew he’d be labeled as a lazy slacker trying to get out of work, and he knew he’d come back to a plethora of papers stacked on his desk.

 

No vacation for him.

 

He checked his watch. It was late, but not late enough for Hifumi to be home yet. He’d gotten a text earlier that day from his friend and roommate, apologizing that there wouldn’t be dinner in the fridge for Doppo that night, since he woke up late, but he’d cook when he got home if Doppo was willing to wait that long.

 

It wasn’t like Doppo couldn’t cook. He just wasn’t very good at it, and often didn’t have the energy for it. That left him with a few hours to kill, unless he bit the bullet and shelled out some cash for take out. He checked his wallet. Hm... No take out for him tonight. Payday was a few days away, at least.

 

Might as well pass the time, then—and he knew the perfect way to do it. He walked down the street to nearby storage lockers, stored his work briefcase and as much of his personal items as he could, then took a detour into a nearby alleyway, ensuring it was empty before he did anything. As embarrassing as it was, Doppo had a… condition. It ran in his family, from what they could tell. Dad’s side. The only ones in the know were, of course, his immediate family, and Hifumi.

 

Werewolfism. Lucky him.

 

Full moons were Hell. He had little to no control over himself, and the form he took was big and ugly and feral, but the rest of the month, he had the freedom to shift at will. The only difference was, his form wasn’t the same. It was smaller. Tamer. More dog-like than wolf-like.

 

Hah. Dog-like. Who was he kidding? He looked like a normal dog. Entirely un-intimidating and kind of pathetic-looking. It felt truer to his real self than his full moon form.

 

He couldn’t find it in himself to hate it entirely, though. Sometimes it was nice to leave his usual worries behind and spend a few hours as a dog, to let himself be doted on by strangers, to be pet and fed and loved…

 

He was really pathetic for that, wasn’t he? But, he did it regardless. It would just be a few hours, he told himself– just a few hours, and then he’d go home.

 

It’s normal, at first–a few kids out with their parents ran up to him, pet him, asked their parents to take him home, only to be told “no” and dragged away. A group of (probably drunk) college students pet him, too, albeit a bit roughly–though one of them fed Doppo some of his leftover takeout. It always tasted better as a dog, for some reason.

 

Nothing out of the ordinary… until someone crouches down in front of him to pet him, and Doppo realizes he recognizes him.

 

“Aw, hey there, handsome guy. Ya lost?”

 

Doppo knew, as a member of Matenrou , the first champion team of the first ever DRB, it was silly to be a fan of any rival team. He could see them as rivals and equals, sure, but to actively root for any of them felt foolish. But a fool he was, because though he kept it a relatively well-kept secret, Doppo was actually a big Buster Bros fan.

 

Huge, actually.

 

Which is probably why he felt his tail wagging at incomprehensible speeds when he realized that Jiro Yamada himself was crouched to his level, petting him with the gentlest smile on his face.

 

“Hm, no collar?” Jiro asks, running his hands around Doppo’s neck, scratching all the while, “Ya seem pretty clean. I don’t think you’re a stray.”

 

He wasn’t.

 

“Where’s your owner? Can ya find your way home on your own, boy?”

 

Yes.

 

But Jiro looks up at the sky, frowning, “Hm, it’s gettin’ dark pretty soon, though…” he seems to mull this over for a moment before looking at Doppo again, giving him another dopey grin, “Ya wanna come home with me?”

 

Yes.

 

 

Yes?

 

Terrible idea. He wasn’t actually a dog. He had a home. A roommate. A job . He could just book it out of there right then and there, disappear out of sight long enough to shift back to human, and go home. Frankly, he should .

 

Why he didn’t, Doppo wasn’t one hundred percent sure. His work day had been pretty bad, yeah, but this was, like, an incredibly bad and stupid idea. Unfathomably so. And yet, he found himself trotting into the home of the notorious Buster Bros less than an hour later, much to the visible surprise of Ichiro, who watched, dumbfounded, as Jiro waltzed into their home with a stray dog.

 

Woof.

 

“Okay, hear me out…” Jiro started, giving Ichiro a very persuasive argument about ‘the dog obviously being lost’ and ‘it getting dark out soon’ and ‘please can we just let him stay the night, I’ll go find his owners tomorrow’. Somehow, it works. Ichiro relents rather easily–probably because he loved his brother so much, honestly, which was very cute–but he comes to find that not… every brother was stoked about this.

 

Ugh , why did you bring this stupid dog home? Isn’t one dog bad enough?”

Saburo Yamada, the youngest of the three, looked at Doppo with what he could only define as disgust. Even so, Doppo wagged his tail upon seeing him. Saburo was his favorite . He was the cutest of the three, with big, pretty eyes, and soft-looking lips, and the cutest little moles on his face–

 

So maybe Doppo had a bit of a crush. On a fourteen year old.

 

Okay, yeah, he was a creep. Whatever . Not like anyone had to know.

 

“Huh? We don’t have another dog,” Jiro points out, confusion evident in his voice.

 

“I’m talking about you , Jiro.”

 

“Oi! Would it kill ya to stop being a brat for, like, two seconds?”

 

“I’m not a brat, you brainless oaf!”

 

“Saburo I’m gonna piss in your breakfast tomorrow if ya keep this up–”

 

“That’s enough, you two,” Ichiro calls from the kitchen, glancing over his shoulder at them with a frown, “Saburo, it’s just for one night. We’ll make sure to keep him out of your room. Okay? Now come help me with dinner.”

 

He grumbles unhappily, but obviously doesn’t want to argue with Ichiro, so he relents, joining his brother in the kitchen.

 

It’s certainly strange to be a quiet onlooker into the domestic evening of the Buster Bros, but it’s really nice, too. They eat dinner amicably, feed Doppo dinner scraps, and all congregate on the couch after to watch a movie together. Ichiro and Jiro smother him in pets and affection, though Saburo pointedly avoids Doppo altogether, wrinkling his nose at him. It’s so cute, Doppo wants to jump him and lick his face. He decides against it. He doesn’t want to give any of them a reason to kick Doppo out of their home.

 

Jiro lets Doppo sleep on his bed with him that night. He expected to find it humiliating, to sleep as a lowly dog at the foot of a teenage boy’s bed, but when he wakes in the morning, it’s the most well-rested he’s felt in a long time.

 

And then he realizes he has work.

 

Fuck .

 

By some miracle, no one else is awake yet, so Doppo’s able to shift back long enough to let himself out of the house, then makes a beeline back to the lockers in Shinjuku to grab his things and head to work.

 

Hifumi had blown up his phone, of course. He’d never come home, after all, so it was understandable that Hifumi would worry.

 

He really doesn’t want to explain where he was, though–not over text. He sends a brief message, hoping it would do for now.

 

“im fine. heading into work now, will fill you in later.”

 

He plans to go home after work. Truly, he does. He plans to go home, tell Hifumi where he was, endure being laughed at and ridiculed by his best friend, and continue on with his life as if nothing had happened.

 

And yet, he found himself waiting outside the Buster Bros residence as a dog that evening, whining to be let in.

 

What the Hell was he doing?

 

Saburo is the one who opens the door. Doppo’s tail wags. He’s so cute he’s so cute he’s so cute . Saburo looks down at Doppo, scowls at him, and calls over his shoulder.

 

“Jiro! Your stupid dog is here.”

 

Jiro appears moments later, shoving Saburo out of the way, “He’s not stupid. Move.”

 

When he sees Doppo, he crouches down, taking his furry, doggy face in his hands.

 

“Well, there you are. I was worried when I woke up and you were gone. How’d ya get outta the house, huh?”

 

“Ichi-nii said it was only for one night, y’know,” Saburo points out as Jiro walks the dog into their home, arms crossed, “He’s not your dog. We can’t keep him.”

 

“We’re not gonna,” Jiro argues, “I’m gonna go out and look for his owner.”

 

“... Right now?”

 

“Yeah, right now. Hang on, lemme just…” he fishes his phone from his pocket and snaps a quick picture of Doppo, then tucks it away again.

 

“There. I’m gonna go ask around Shinjuku. And, uh, I guess if I can’t find ‘em, I’ll make posters or somethin’.”

 

He’s in the process of slipping on his shoes when Ichiro enters the room, gaze flickering to Doppo, “Oh, the dog’s back.”

 

“Jiro’s gonna go look for the owners.”

 

“Right now? It’s getting late. Why don’t we just let him stay another night? We can look for his owners in the morning.”

 

Saburo groans dramatically. Doppo guesses he doesn’t like dogs much. It’s hard not to take it personally. But, maybe he’ll come around?

 

The rest of the evening is as pleasant as the last. He’s pet again, fed again, and this time, Ichiro lets Doppo sleep on his bed.

 

He doesn’t run away the next morning. It was Saturday, after all–one of his days off. He’d texted Hifumi in advance this time, and prepared for a relaxing weekend of being pampered and pet.

 

Doppo knew they wouldn’t find his “owners”. He didn’t have any. He’d just stay in their home and enjoy their affection–until the moment one of them mentioned taking him to a shelter, at least, then he’d split and never come back. But, maybe if he was lucky… they’d take him in.

 

What the Hell are you thinking? You’re not a dog. You can’t live here.

 

He knew it was better to just go home. To never come back. But rationality be damned, Doppo was having a good time living as a dog, so he stayed put.

 

Of course, Ichiro couldn’t find his owners. He printed a few “found dog” signs, but Doppo knew no one would respond to them.

 

Doppo overhears Ichiro tell his brothers that evening that they’ll keep the dog–until the owners contact them. Jiro’s obviously overjoyed, but Saburo… not so much.

 

When he goes back to work on Monday, he tells himself he’s going to go home, this time. He’s not going to play pet anymore. It was fun while it lasted, a nice relaxing weekend of acting the role of a common housepet, but he wasn’t going to do it anymore. He was a grown man with an adult job and an apartment and bills and he wasn’t going to sit on the floor and beg for food and sleep on the bed of someone ten or more years younger than him. It was embarrassing. Undignified. He was better than that.

 

“Your stupid dog’s back, Jiro.”

 

“Oh, there he is. Was wonderin’ where he went.”

 

He wasn’t better than that.

 

It only takes a few days before Jiro does something Doppo… hadn’t anticipated.

 

“How do ya feel about Shiro as a name?”

 

Saburo and Doppo stared at him in unison.

 

“A name? You can’t give him a name.”

 

“Why not?”

 

“Because he already has an owner and a name, and you’re just going to confuse him,” Saburo argues. “Besides, if you name him, you’ll just get attached to him.”

 

“Well we can’t just call him ‘dog’.”

 

“Why not? That’s what he is.”

 

“Whatever. I’m callin’ him Shiro.”

 

Doppo supposed it fit the Yamada naming convention, though he wasn’t exactly stoked to have a new name. He liked Doppo. It fit him. He should just ignore Jiro whenever he was addressed by this new name–maybe that would get him to drop it.

 

“Shiro, dinner!”

 

Oh, Hell yeah, dinner time.

 

By the following Saturday, it seemed Ichiro and Jiro had all but given up on ever hearing from Doppo’s “real” owners.

 

“Can we get him a collar?” Jiro asks, holding one of Doppo’s paws in an attempt to teach him to “shake”.

 

“Sure,” Ichiro responds simply.

 

Saburo looks at his older brother in shock, mouth agape, and though it’s obvious he wants to protest… he doesn’t. He closes his mouth and sinks into the couch cushions, arms crossed, pouting. He looks over at Doppo, sighs, and seems to resign himself to his fate.

 

Doppo wakes in the middle of the night, the reality of the whole situation dawning on him.

 

Uh-oh.

 

How the Hell was he gonna keep this up? Surely they’d get suspicious eventually about how Doppo manages to escape every weekday morning. What if they try to go on vacation with Doppo? How will he get out of work? What if they take him to the vet for shots? What if they try to neuter him?

 

He’s home in under an hour, rudely shaking Hifumi awake in a panic.

 

Groggily, Hifumi sits up in bed, obviously drained, and rubs his eyes.

 

“Wh… Doppo? You’re finally home… what time is it?”

 

“Uh, I don’t know. Three?”

 

“In the morning?” Hifumi yawns, stretching his arms over his head. He rubs his eyes again, blinking them open slowly, “Whoa, ya look like shit. What happened? Kill a man and need help hiding the body?”

 

“Hifumi, I’ve been staying with the Buster Bros as a dog and I think I’m their pet now.”

 

It takes far too long for his words to sink in, but when they do, Hifumi laughs so hard that he nearly falls out of bed. Nearly .

 

It takes ten minutes to get Hifumi coherent again, and finally his friend asks him to explain from the beginning.

 

Once Doppo does, Hifumi’s grinning at him, biting his lip like he’s trying to keep from laughing again.

 

“It’s not funny.”

 

“Aw, Doppo, c’mon. It’s hilarious. You’re their pet . Their doggie.”

 

“I am not.”

 

“You live there outside of work hours. They named you Shiro. They got you a collar . You’re their pet.” He pauses, giggling into his hand, “Can I see it? The collar. I bet it looks cute on you.”

 

Hifumi.

 

“Sorry, sorry,” Hifumi sing-songs, not sounding sorry in the slightest, “If you’re that freaked out, just stop goin’ over. They can’t figure out your secret if ya disappear.”

 

“But then they’d be sad…”

 

Hifumi chuckles, ruffling the hair on Doppo’s head, “Aww, what a good doggie you are. You care about your owners sooooo much.”

 

Doppo knocks his hand away, “Fuck off. I just… what do I do?

 

“Well, if it makes ya happy, just keep doin’ it, I guess. They don’t gotta know.”

 

“I can’t keep this up forever, Hifumi.”

 

“Then, I dunno, tell ‘em the truth. Maybe they won’t mind.”

 

“They’ll call the cops on me.”

 

“Ya sure?”

 

“Why the Hell wouldn’t they? Any rational person would call the cops if they found out a grown man twice their age was secretly living with them as their pet dog .”

 

“Well, when you put it like that …”

 

“Hifumi, seriously. What do I do?”

 

“Maaaan, I dunno. Just do what makes ya happy, Doppo.”

 

That wasn’t really helpful, but Hifumi was obviously exhausted and not exactly an expert in werewolfism, and wound up rolling over and going back to sleep before Doppo could get another word in.

 

I guess I’ll just go home, then.

 

He’s out the door before he realizes he saw the Buster Bros residence as home .

 

Fuck .

 

He sneaks back into the Buster Bros residence without any issue, shifting back into a dog the moment the front door is closed and locked. He heads back up to the bedrooms, wondering which bedroom to settle down in, when he realizes Saburo’s bedroom door is open.

 

He’d never slept in there before. Saburo always kept his door closed to keep him out, but now that it was opened… he couldn’t help himself.

 

Saburo was asleep when he entered–understandably, as it was the middle of the night. He hoped Saburo wasn’t a light sleeper as he hopped up on the bed and settled on top of the boy’s legs.

 

He wakes an hour later when Saburo stirs, and upon lifting his head, he finds the boy staring at him with a frown. Uh-oh. He was gonna get kicked out of Saburo’s room, wasn’t he? He supposed it was inevitable…

 

Saburo clicked his tongue, muttering, “Whatever,” before plopping his head back on the pillow and going back to sleep.

 

Huh. Progress.

 

It’s in the middle of dinner the next evening when Saburo gets up to refill his cup, passes by Doppo silently, and pats him on the head as he goes.

 

Doppo thinks he imagined it at first, until Saburo comes back and does it again . He’s certain his tail has never wagged so fast.

 

He can’t help but start pushing his luck. He starts laying on Saburo when the three brothers are trying to watch TV in the evenings, and though he’s shoved away at first, Saburo starts to, begrudgingly, accept it. He tries to sneak into Saburo’s room at bedtime, and though sometimes he gets the door shut on his face, sometimes he makes it inside, and Saburo doesn’t bother to force him to leave. Sometimes, when Saburo’s busy clacking away at his computer keyboard, Doppo flops on the ground beneath the desk, and Saburo actually lets him stay there. What a lucky dog he is.

 

One Sunday afternoon, Doppo finds Saburo’s door cracked, so he nudges his way inside. Saburo’s on the floor, folding laundry, and Doppo drops down beside him and rolls onto his back, staring up at Saburo, silently pleading. He hadn’t been properly pet by him, not yet , but if he kept trying, then maybe he’d get lucky.

 

Saburo stares at him a moment, sighs, and drops one hand on Doppo’s stomach, rubbing gently.

 

Holy shit this was actually happening. Yes yes yes.  

 

“Sheesh, keep wagging your tail like that and you’ll punch a hole in the floor,” Saburo says, rubbing Doppo just a bit harder.

 

Heaven. This was heaven. Saburo was actually giving him attention and a fraction of affection. He was so lucky. Being a dog was worth it, why was he ever worried? Ah, Saburo’s hand was so soft, too…

 

“Dogs are so simple,” Saburo mutters, curling his fingers to scratch at the skin of the dog’s stomach, “I barely do anything and you’re just soooo happy, wagging that stupid tail of yours.”

 

Yes. Yes, it was true, but Doppo really liked Saburo, so could he really be blamed?

 

Saburo places his other hand on Doppo’s stomach, giving his full attention to the dog, ignoring the laundry he had been attempting to fold one-handed, and starts to coo .

 

“Aw, you’re just a big dumb dog, aren’t you? Just a big stupid fuzzball, huh?”

 

Hm, okay, though he was kind of mean , Doppo couldn’t help but be entirely dog brained, focusing more on the cutesy tone of voice than anything, wiggling excitedly as Saburo gave him the best belly rub to end all belly rubs. He loved it. He had Saburo’s attention, his hands on him, a cute little smile on Saburo’s face…

 

And then it falls. Saburo scrunches his nose and pulls his hands back, recoiling, “ Ew , Shiro, that’s disgusting.”

 

Huh?

 

… Oh. He’d hardly realized that he’d popped a boner until then. Well, not like it was entirely his fault . Saburo was cute, and was doting on him when he never had. Who wouldn’t get excited? So sue him.

 

“Ugh, gross , get out of here,” Saburo scoffs, rolling Doppo onto his legs and ushering him out the bedroom door, closing it the moment Doppo’s tail clears the opening. No matter how long he sits outside the room and whines, scratching at the door, Saburo doesn’t open it again.

 

The next day at work is abysmal. He spends the whole day down on himself, certain that he’d royally fucked up his chance at getting Saburo to actually like him. He still had the attention and affection from Ichiro and Jiro, sure, but Saburo is the one he really wanted it from.

 

Good job, Doppo. You fucked it all up, with your stupid, excitable dog hormones.

 

Imagine his surprise when he arrives home that evening, slips through the doggy door Ichiro had so nicely installed for him, and finds the house empty–save for Saburo, who hardly noticed Doppo entered, giving him ample time to peer up at the screen and see what he was doing.

 

No fucking way.

 

Saburo realizes he’s not alone and jumps, minimizing at record speed before spinning around, eyes wide. He relaxes almost instantly, letting out a deep sigh.

 

“Oh. It’s you. Geez. You scared me, stupid dog.”

 

He spins back around in his chair, glancing at Doppo and hesitating before re-opening the minimized window.

 

“I know you don’t understand what any of this is, but since it’s technically your fault, I can’t help but feel weird about you being here… can’t you go nap in Jiro’s room or something?”

 

Nope.

 

Saburo sighed.

 

“Fine. Whatever.”

 

He turns his attention back to the computer, and Doppo watches as Saburo, somehow , probably using a fake ID or something, orders what is undoubtedly a dog dildo.

 

For days, he can’t get it out of his mind. He popped a boner, and Saburo was interested enough to buy a dog dildo ?

 

He bounced his leg, trying to focus on his work. It was a Friday, at least, which meant he got the weekend to relax with his owners, but work was the last thing he wanted to do right now. It was barely 2pm, how the Hell was he going to survive until 5?

 

Don’t think too much into it. He’s a teenager. He’s just curious. Curious and horny and with a strong enough sense of morality to not want to fuck an actual dog. It’s not that big of a deal. People use weird animal dildos all the time. Hifumi has a horse dildo, for fuck’s sake. It’s not that weird.

 

It was impossible to stop thinking about it, though–not when he wanted Saburo as bad as he did. And here Saburo was, planning on fucking himself on some stupid fake dog dildo when Doppo could supply the real thing –and he wanted to. God, he wanted to so badly . Just the thought of it, of pounding Saburo into the mattress and making him cry and cum on his cock–

 

Snap!

 

He’d forgotten he was holding a pencil until half of it went flying across the room.

 

God, he was so fucked.

 

He was certain the universe was testing him, punishing him, when he came home that night to find, once again, that Ichiro and Jiro were gone.

 

But Saburo was home. And the sounds coming from inside his room, though muffled, were unmistakable.

 

He was pleasuring himself.

 

He was pleasuring himself, without Doppo .

 

The temptation to shift back to a human and barge into Saburo’s room was nearly too much to bear, but he held back. He held back and scratched at the door, and whined, and barked , because he needed to be in there, he needed to be in there now , and Saburo was obviously ignoring him.

 

Until finally the door opened, and a flushed and nude Saburo cracked open the door and glared down at Doppo.

 

No , Shiro,” he hisses, “I’m busy . I’ll let you in when I’m done.”

 

Fuck that, Doppo wasn’t waiting any longer. He barged in, using as much strength as he could muster with his little dog body, and Saburo stumbled backward, shocked. He watches Doppo settle himself at the foot of Saburo’s bed, sitting, wagging his tail, waiting . Saburo stares at him, hesitating, looking back and forth between Doppo and the empty hallway, but finally relents.

 

“Fine. Fine . Ugh , this is so weird . Just be quiet so I can forget you’re even here.”

 

Doppo watches Saburo close and lock the door before settling back in bed, grabbing the toy he’d left waiting atop his bedsheets, then slowly parted his legs and guided the toy inside him.

 

Fuck . Fuck fuck fuck, this was so unfair. Saburo was right there, eyes closed, those cute little tits of his rising and falling with each breath, one of Saburo’s hands playing with his perky nipples as the other gradually fucked himself on the toy. On that stupid little knotted dog dildo, a cheap replica of the actual thing.

 

He couldn’t stand it.

 

To Hell with it.

 

He jumped onto the bed, nudging Saburo’s hand away with his nose. Saburo jumps, startled, releasing his hold on the dildo without a second thought, “Wh– Shiro! No, bad dog, get off the–”

 

Before Saburo can try and shove him off, Doppo latches his teeth around the stupid little toy and wrenches it out, flinging it to the floor unceremoniously. Saburo watches it go, absolutely dumbfounded, starting to prop himself up, but Doppo quickly settles over him, using as much of his weight as possible to keep Saburo pinned. He wasn’t exactly the strongest in his dog form, but he was at least stronger than the average dog–enough so that he could most likely keep Saburo pinned like this.

 

Good.

 

“Wh-what the Hell are you doing , you stupid dog, get off –”

 

It takes a moment to adjust the placement of his legs, but once he’s certain he’s lined up, Doppo doesn’t wait a moment longer. He’s already hard–how could he not be, seeing Saburo like this?--and his dog cock slides right inside Saburo’s already well-fucked pussy with ease, like it was waiting for him.

 

He watches Saburo’s eyes go wide in shock and terror, pushing his hands against Doppo, “No, nonono, what are you– stop , you stupid dog, you can’t just–you–!”

 

Doppo vastly preferred Saburo when he was moaning, but it seemed he wasn’t quite at that point again. No matter, he just needed to get him to that point. He presses his face against Saburo’s, parting his maw and letting his tongue flop out of his mouth, and forces it past Saburo’s protesting lips, silencing him entirely.

 

He’s not surprised Saburo struggles against him, kicking his legs and shoving him with his hands, shaking his head to try and get Doppo’s tongue out of his mouth, but ultimately, he was trapped. Doppo had the upper hand, and he wasn’t giving it up. He licked into Saburo’s mouth, his large tongue messily lapping at whatever he could reach, licking Saburo’s teeth and dragging their tongues together as he thrusted his hips, faster and faster. He felt like his cock was on fire , arousal at a high he never knew it could be. Saburo’s pussy was absolute heaven , so tight and wet and perfect for him, sucking him in like it wanted to be bred, like it wanted to milk every last drop of his cum, like it was asking for his knot.

 

The bed beneath them squeaked with every thrust, and as Doppo came closer and closer to release, Saburo’s struggling gradually began to taper off, his muffled cries of protest slowly turning to cries of pleasure . Maybe he was crazy, but it felt like Saburo was kissing him back , pressing his tongue against Doppo’s as he gasped and whined and squeezed his legs against Doppo’s flank.

 

When Saburo started rolling his hips in time with Doppo’s thrusts, it was all too obvious that he’d finally given in. He’d finally allowed himself to give in to sheer pleasure–and Doppo was all too happy to give it to him.

 

He feels his knot start to swell. If he wanted to do this properly, he had to do it now . He thrusts into Saburo again, his knot catching at the entrance to Saburo’s pussy, just slightly too big to fit. He wasn’t a quitter, though–not today. He pushes, hard , cock twitching as Saburo cries out in pain as his knot slowly forces itself inside.

 

“S… sto–h-hurts–!” Saburo manages to cry around Doppo’s tongue, but he’s ignored as finally, thankfully , the knot slips inside and swells to its full size, keeping the two locked together as he cums, cock emptying wave after wave of cum deep into Saburo’s pussy. As he filled the boy to the brim, Saburo’s body shook, pussy clenching around Doppo’s knot as he squeezed his legs tight, back arching as he came with a hoarse cry, practically convulsing around Doppo’s cock.

 

Saburo’s body goes limp, chest heaving, breathing hoarse as he struggles to catch his breath, and with his tongue free again, Doppo gently laps at Saburo’s chest, licking beads of sweat off his cute little chest. He wanted to feel the lumps of flesh beneath his hands, his human hands, but this would have to do for now. Maybe one day he’d reveal himself to Saburo, but not now. Not while his knot had yet to go down.

 

He rests his head on Saburo’s chest, wagging his tail as he waits for the knot to deflate on its own. Saburo doesn’t say anything, though he does weakly scratch behind Doppo’s ears, which he takes as a good sign.

 

When his knot finally goes down, Doppo sadly, reluctantly, pulls out of Saburo–though he enjoys watching a steady stream of cum trickle out onto the bed sheet.

 

He watches Saburo slowly push himself up on shaky arms, roll off his bed, and waddle to the bathroom. He pauses at the door, looks over at Doppo, and parts his lips to speak.

 

“I… know you can’t understand me, but…” he hesitates, closing his eyes and scoffing at himself, “I can’t believe I’m talking to a stupid dog…” he shakes his head and opens his eyes again, “... uhm… Ichi-nii and Jiro are gonna be gone tomorrow, so…”

 

He pauses, as if waiting for a response, and Doppo wags his tail, hitting it against the ground with a happy thump, thump, thump .

 

To his surprise, Saburo blushes .

 

Blushes!

 

“Ugh, what the fuck is wrong with me…” Saburo mutters, dipping out of the room to take a bath.

 

Hm. Wasn’t there a school break coming up soon? Maybe he’d take some time off of work to spend it with Saburo. He had a feeling he’d be staying up awfully late anyway, in the nights to come.

Notes:

If I had a nickel for every time I wrote a fic for Roo about Doppo turning into an animal and fucking Saburo's tight underage boy pussy, I'd have two nickels. Which isn't a lot, but it's strange it's happened twice.
