My Puppy

Summary:

“He’ll be fine. He’s just excited because I told him I have a surprise for him, but that he has to wait until after the party,” Keiji explains, much to the amusement of the two men standing opposite him.

“Bokkun doesn’t strike me as the patient type,” Atsumu snorts and Keiji shrugs, taking a long sip of the cola in his glass before answering him.

“He might surprise you. He can behave when he’s properly motivated.”

Notes:

A late birthday gift for Kou born of a brainrot post I made on my nsfw twit.

Please read the tags! This fic features puppy play and Dom/sub elements. Bokuto and Akaashi are both transmasc and I use terms like cunt/cock interchangeably.

This is wildly self indulgent, Bokuto just strikes me as someone who would be into puppy play and then I wrote 4500 words of it. I hope you enjoy!

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

Work Text:

“Is he alright? He’s been bouncing around the room like an excitable puppy all evening,” Sakusa asks dubiously, staring over the rim of his glass at Koutarou as he flits from group to group, looking very much indeed like a puppy meeting new people for the first time. The dog costume may be contributing very much to the effect.

Keiji chuckles softly from behind his own glass, glancing at his energetic boyfriend for a brief moment before returning to his drink.

“He’ll be fine. He’s just excited because I told him I have a surprise for him, but that he has to wait until after the party,” Keiji explains, much to the amusement of the two men standing opposite him.

“Bokkun doesn’t strike me as the patient type,” Atsumu snorts and Keiji shrugs, taking a long sip of the cola in his glass before answering him.

“He might surprise you. He can behave when he’s properly motivated.”

Keiji sets his glass down on a side table and goes to collect Koutarou before he trips over something and hurts himself. He catches him from behind as he’s about to breeze by and gathers him against his chest, pleased when Koutarou realizes it’s him.

“Keijiiii, please,” he whines in a low, rumbling whisper and Keiji grins, hooking his chin over Koutarou’s shoulder and keeping him close with an arm around his slim waist.

“Are you enjoying your party, Kou? All of our friends are here to celebrate Halloween with us. They even got dressed up for the occasion, you should be more excited,” he teases softly, subtly nudging his leg against the crease of Koutarou’s ass.

To anyone else it just looks like a couple playing around with the theme of their costumes. After all, Keiji is dressed as a dog catcher to Koutarou’s puppy.

He even reaches up to pat between the fluffy ears perched in Koutarou’s hair, knowing that it’ll make him pliable putty goo in Keiji’s hands. Koutarou’s back arches at the contact to his ass, and then he goes predictably still as he’s pet like a real dog.

“Do you think you can be a good boy for me? It’s only another hour and then people will start heading home, I’m sure you can handle that,” Keiji purrs and reaches down to tug at the tail sticking out of a small, nearly invisible hole in Koutarou’s jeans.

Only they know that the tail isn’t attached to him by a safety pin or clasp.

“I’ll be a good boy, I promise,” Koutarou gasps, and Keiji makes a pleased noise before planting a kiss on his cheek.

“Promise who?” he asks innocently, tugging on the tail again.

Koutarou twitches and Keiji suddenly finds himself wishing he could send everyone home early as well.

“I promise, Master,” he whispers and Keiji finally releases him with a pat on the head, right between his white fluffy ears.

“Good boy,” he murmurs just to see Koutarou light up, and if Koutarou’s tail were real it would surely be wagging right about now.

He bounces off again to go entertain their guests and Keiji casts a furtive glance around before he returns to his drink and his companions, who apparently got bored and decided to make out instead of talking to anyone else. Keiji chugs the rest of his cola and leaves them to it, meandering around the room in search of better conversation.

He ends up finding it in Koutarou’s team captain and that’s where he remains for the following hour, trying his best to look like he isn’t obsessively checking the clock. Finally people start to make their way to the doors though and Keiji smiles and thanks them all for coming while Koutarou hovers.

Keiji can feel him nearly vibrating out of his skin with impatience but he makes a good show of being a gracious host, and when he finally closes the door behind the final guest he turns to Koutarou and offers him a soft, pleased look.

“You were such a good boy, puppy… Master is very proud of you for behaving tonight,” he croons, reaching out to pat Koutarou’s head between his big fluffy ears.

Koutarou lights up like a firework and Keiji doesn’t have to even give the command before he’s sinking to his hands and knees in front of him, peering up through the soft fringe of his bangs like he hung all the stars in the sky.

“Go get your things and meet me back in the living room. Do you need Master’s help getting undressed?” Keiji asks gently, studying Koutarou’s already blissed out face. Poor thing must have been on the edge of dropping for a while just from wearing some of his puppy gear and from Keiji making him call him Master in a crowd of people.

Koutarou always slips into his headspace rather easily once Keiji stops using names.

He shakes his head at Keiji and crawls off to do as he was ordered and Keiji watches him disappear down the hallway before he slowly sinks onto the couch, pleased that their party had been rather small. There’s only a few stray glasses on various surfaces around the living room and kitchen area, but those can be dealt with after Keiji has taken care of his puppy.

Tossing the dog catcher costume hat aside, Keiji leans back onto the couch and makes himself comfortable, turning the television onto whatever drama is currently playing.

Koutarou knows not to dawdle so Keiji relaxes while he waits, enjoying the peace of an empty house.

When Koutarou returns he’s still on all fours but no longer wearing the clothing from earlier. He has a new plug inside his ass and Keiji is amused to see it’s Koutarou’s favorite one, with a plush, fluffy white and grey tail attached that Keiji had custom ordered himself just for his favorite puppy. He has his ears still perched on his head and he’s brought his puppy paws with him, which means he really wants to go deep this time.

Keiji chuckles and sits up so that he can help him slide the soft leather mitts onto each of his hands, tightening the buckles around his wrists so he won’t be able to remove them by himself. They’re lined with soft fur on the inside to keep Koutarou’s hands comfortable and stylized with a dog paw design on the bottom, which Keiji finds rather cute.

“My good boy… You really need this, hmm? It’s been a while since we last played with your puppy paws,” he chuckles softly, and Koutarou bobs his head before offering Keiji his collar as well.

Already nonverbal, too.

Keiji feels a little bad as he accepts the custom made leather collar. The tag dangling from an o-ring at the front has ‘Kou’ inscribed on one side and Keiji’s name on the other, and Keiji runs an absentminded finger over the engravings.

He’s been working so much lately that he and Koutarou hardly have time for vanilla sex, nevermind a whole scene, but Koutarou relies on this type of play to blow off steam and manage the stress of all the expectations and struggles he faces as a professional volleyball player. If he goes for too long without Keiji putting him under he starts to overwork himself at the gym to manage the buzzing in his brain, and he begins to get anxious and easily overwhelmed.

The fact that he’s already so deep just from wearing his puppy costume pieces and a few words of praise from Keiji is a testament to just how much he’s needed this.

“I’m sorry I haven’t been around much these past couple weeks. Master promises to be better for his puppy, okay?” Keiji murmurs, buckling Koutarou’s collar on and stroking the soft skin of his neck.

Koutarou gives him a dazed, happy smile and nuzzles his face into Keiji’s arm, like he’s just happy to be there and have Keiji’s attention.

He takes Koutarou’s pillow from the couch and sets it on the floor at his feet, then lazily spreads his legs. Koutarou immediately obeys the unspoken order and crawls around to kneel on the pillow, keeping his paws on the ground and leaning forward to rest his chin on Keiji’s thigh.

“Such a good boy for me, puppy… Don’t even need to tell you what to do half the time,” Keiji sighs contently, slipping his fingers into Koutarou’s hair and scratching idly at his scalp.

He undoes his belt and zipper one handed while continuing to pet Koutarou’s head, planting his feet on the ground and lifting his hips to shove his pants down so he can kick them off and away. He drops his hand between his thighs and slides his fingers through his folds, gathering up some of the slick that has accumulated and using it to ease his way as he fingers at his small cock.

“Master wants to watch some TV, puppy. Why don’t you be a good boy and keep me warm?” he instructs and sinks down a little more into the couch to make it easier for Koutarou to get to him.

He hooks his legs over Koutarou’s broad shoulders and lounges back into the couch cushions, wiping his hand off on his own thigh before settling in to let Koutarou do all the work.

Like the obedient puppy he is, Koutarou buries his face between Keiji’s legs and licks at his wet pussy, thick tongue delving between the lips to taste before lapping his way up towards Keiji’s cock.

His wide mouth seals over his cock and cunt and Keiji huffs out a comfortable breath, resting his hand on top of Koutarou’s head and lazily stroking through his hair.

Koutarou’s lips are soft and wet against Keiji and he does his best to stay still while he cockwarms him, earning soft murmured praises from Keiji occasionally as he pretends to watch whatever is on the television through one entire episode, and then into a second.

Mostly he just watches Koutarou.

His puppy’s eyes are shuttered and his expression is relaxed and honest in his simple enjoyment of the scene. Koutarou likes doing things that make Keiji feel good, and cockwarming is one of his favorites.

Keiji certainly isn’t complaining and he bites back a small hiss of pleasure when Koutarou swallows and his mouth moves against his cunt by a small fraction. He pushes Koutarou’s face down a little harder and grinds himself onto his tongue, pleased when Koutarou gets the memo and wriggles his tongue against his cocklet.

Giving up all pretense of watching the television now, Keiji curls his fingers into Koutarou’s hair and tugs him closer, rocking himself up into his mouth with a soft, needy groan.

“Master is going to fuck your face, puppy. Pinch my thigh if you need to stop or slow down okay?” Keiji pants, waiting for Koutarou to bob his head slightly in acknowledgement before he bucks his hips upwards against his waiting mouth.

Koutarou is obediently still as Keiji uses him for his own pleasure, his mouth open and his tongue out for Keiji rub himself off on. Keiji grinds his cock into his puppy’s soft palette and groans at the harsh stimulation, shuddering as a familiar heat starts to build in the pit of his stomach.

Keiji holds his head down through his orgasm, his breathing coming in rough, ragged gasps. When it’s over he gets a look at Koutarou’s face and is amused by the mess of slick covering it from his nose down.

“Such a good puppy…” he murmurs, loosening the deathgrip his thighs have on Koutarou’s head. “Do you want to go play with your toys now? A treat for being so obedient for Master.”

Koutarou rests his chin on Keiji’s knee and grins dopily at him, and Keiji can see the way his hips swing back and forth, making the plush dog tail wag back and forth as well. He’s so cute that Keiji can’t resist retrieving his phone and snapping a few photos. They’ll go with the rest of his collection in a password locked folder on his laptop for safekeeping, so no nosy busy bodies can find them.

Keiji peels his shirt off and leaves it somewhere on the floor on their way to the bedroom, mulling over his options for what kind of toys he can use on his precious puppy. After rummaging through their toy chest for a bit while Koutarou gets comfortable on the bed, Keiji ends up with their favorite strap, a short paddle, and the leash that goes with Koutarou’s collar.

He clips the leash onto the o-ring and then cups his palm against Koutarou’s cheek, smiling when Koutarou gives him a dreamy, happy look.

“My puppy is down deep tonight… Can you tell me your color, baby?” he murmurs, reaching up to scratch his fingers between Koutarou’s dog ears.

“Green,” Koutarou sighs softly, and Keiji rewards him for getting the word out with a kiss to his forehead.

He wipes the remaining slick off Koutarou’s face with a towel from a stack he had set up prior to the party in preparation for this, and then tugs on the leash to guide Koutarou across their massive bed to kneel on some more towels he had spread out earlier as well. Ideally he wants to be able to put his puppy to bed after this without having to change the sheets, but Koutarou is a messy boy.

“Master’s going to fuck you, but first, you know he has to punish you right?”

Koutarou sits back on his heels and gives Keiji a sad, confused look, and it pulls on Keiji’s heartstrings even though he knows it’s just part of the scene. He had been the one to request that Keiji start incorporating punishments into their play for mistakes Koutarou makes during his games.

It’s cathartic, he had insisted. It helps with the guilt and the frustration if Keiji punishes him, even if his ‘mistakes’ aren’t truly mistakes but merely just the other team playing better.

Plus, Koutarou likes the pain. He’d said so himself through a dark blush that Keiji found irresistibly adorable. But he’s such a good puppy all the time for Keiji that it’s hard to find reasons to punish him for anything normally.

And so they worked out a system. Keiji can’t complain though. He likes how good red looks on Koutarou’s body after he’s spanked him to tears.

“Don’t make that face at me. You know what you did. Letting Kageyama-kun get that many service aces past you… That was a very, very bad boy,” Keiji growls, picking up the paddle and raising an eyebrow at Koutarou.

“Head down, ass up, puppy. Don’t make me ask you a second time or I’ll add more.”

Koutarou obeys instantly, his back bowing and muscles rippling in a way that makes Keiji’s mouth water just looking at him. His strong arms are folded in front of him to pillow his head on his puppy paw hands and his knees are already spread just like Koutarou knows he likes it.

He cups his palm against Koutarou’s soaking cunt and chuckles faintly, teasing through the slick folds and wet curls of silvery pubic hair for a moment just to make Koutarou squirm before he pulls away.

“Already so needy just from a little bit of play. Poor puppy… Master’s going to take good care of you, I promise,” he coos, and when he lightly grazes Koutarou’s thigh with the paddle it makes him twitch.

“I think fifteen should be enough to teach you a lesson. I want you to ‘woof’ after each one, baby, can you do that? If you miss one then I’ll have to start over until you get it right.”

Koutarou twists his head to look at Keiji and lets out a soft, low ‘woof’ to show that he understands.

Keiji smirks and rubs the edge of the paddle against Koutarou’s plush ass, studying him through narrowed dark eyes.

“Good boy.”

And that’s all the warning Koutarou gets before Keiji strikes him with a loud, harsh smack. The blow lands on the meat of his ass and Koutarou yelps at the sudden spike of pain, then remembers to make a ragged ‘woof’ sound as instructed.

Keiji keeps an eye on Koutarou’s face as he lands the next few spanks, watching as his eyes glaze over and he starts to pant between each obedient ‘woof’. He always gets so pliant when he’s being spanked and today is no exception.

“You’re being such a good boy, puppy… Master is proud of you for taking your punishment so well,” he purrs softly, leaning in to kiss one of the red marks he’s left on Koutarou’s ass.

He taps the paddle against the buttplug just to watch him squirm at the stimulation, then without warning lands another spank on the crease between his ass and thigh.

He waits for Koutarou’s woof and then quirks an eyebrow when Koutarou doesn’t make a sound.

“Are you forgetting something, pup?” he growls and Koutarou jerks, gasping out a strangled ‘woof’ in response.

Koutarou’s ass is red and hot to the touch by the time Keiji is finished and he sets down the paddle in favor of smoothing his hands over no doubt aching flesh, digging his fingers in slightly and watching as Koutarou trembles. There’s drool at the corner of his mouth and he’s well and truly deep into his headspace now, which is exactly where Keiji wants him.

Hazy golden eyes stare at him as he slowly buckles the strap on into place. It’s a deep purple color and veiny with a nice girth to it, which is why Koutarou likes it so much. Keiji positions the hollow base over his own small cocklet and rocks his hips a bit to test the fit before settling between Koutarou’s legs and brushing the fat, flared head of the dildo against Koutarou’s pussy.

His hole clenches and a dribble of slick oozes out, dripping onto the towels that Keiji set out.

“So messy, puppy. You’re already soaked and Master hasn’t even fucked you yet,” he murmurs, positioning the toy against Koutarou’s cunt and rubbing it through his slick folds to get it nice and wet.

He loops the leash around one hand and grabs hold of his tail in the other, tugging slightly just to make the heavy glass plug slide out a little bit.

“You better keep this toy in your ass if you want Master to let you come tonight. Bark if you understand, pet,” he orders, pleased when Koutarou immediately lets out a short bark.

Keiji uses the hand holding the leash to position the dildo, knowing that it’s tugging the collar against Koutarou’s throat to do so, and slowly pushes his way into Koutarou. He’s so wet and needy that the glide is easy and Keiji licks his lips, enjoying the sight of the thick toy disappearing into his body.

“You’re sucking me in, puppy. You really needed Master’s cock,” he purrs, tugging sharply on his tail and pleased when Koutarou clenches up, preventing the toy from sliding out of him.

“Good boy, Kou.”

Keiji pulls out and fucks back into him hard, hissing at the stimulation to his sensitive cock. Koutarou had asked him for rough though so he doesn’t waste time on preamble and sets a brutal pace from the start. The wet sucking sounds Koutarou’s cunt makes each time Keiji moves are intoxicating, and the man himself is gasping into the towels, puppy paws digging into the mattress to push himself back onto Keiji’s cock.

The bounce of his ass every time Keiji’s hips slap against it is so delicious and Keiji spanks him with his open palm to watch the muscle jiggle and clench just in time to prevent him from pulling the plug out of his ass again.

“Such a good fucking puppy for me,” Keiji snarls, yanking on the leash until Koutarou is forced to pull his head back to relieve the pressure of the collar around his throat.

He leans over Koutarou’s prone body and crushes their lips together, forcing his tongue inside to chase the lingering taste of himself in his mouth. He licks a hot stripe over Koutarou’s soft palette, swallowing his puppy’s desperate sob as he pistons his hips against him.

“You’re gonna come untouched, puppy, you understand? If you’re a good boy and do this for Master then I’ll touch your pretty cock but you’re gonna come on Master’s cock first,” he growls against his lips before pushing Koutarou’s shoulders back down into the bed.

Koutarou sobs out a ragged little bark of acknowledgement, and Keiji laments that he looks so pretty with tears on his face.

He spanks his ass again and Koutarou clenches, and Keiji knows he’s approaching his limits by the way his thighs have started to shake.

“Come, puppy,” Keiji orders and Koutarou cries out as he spasms and comes hard around the dildo.

Keiji fucks him through it, angling his hips so the fat head grinds against Koutarou’s g-spot with each in and out movement. Then he pulls out and unbuckles the strap, setting it aside on a towel to be cleaned later.

“Roll over onto your back, puppy,” he murmurs, guiding Koutarou over until he’s sprawled on the now damp towel.

Slick and come drip out of him and Keiji makes a soft, pleased noise as he straddles Koutarou’s hips.

“So wet and messy for me, baby. You’re beautiful like this,” Keiji sighs and strokes a single fingertip up the length of Koutarou’s cocklet.

It’s still stiff with arousal and Keiji smirks when Koutarou’s hips buck up at the contact.

“Color, puppy?”

Koutarou stares dazedly at him and Keiji realizes he may be too deep in his puppy headspace to make the words anymore. He leans down and presses a kiss to Koutarou’s sweat damp forehead, stroking his fingers soothingly through his hair.

“Nod for green, shake your head for red. Can you do that for me, puppy?” he asks softly, and Koutarou blinks dazedly at him before he nods twice to both of Keiji’s questions.

Keiji smiles and rewards him with another kiss, scratching his fingernails behind one of Koutarou’s human ears until he’s squirming again.

“Good boy, Kou. I’m so proud of you. Master is going to ride your cock, okay? You can come whenever you need to but I’m not going to stop until I’ve come too.”

Koutarou nods again and Keiji sits back up, positioning himself over Koutarou’s cocklet once more. His cock has grown longer than Keiji’s in the years they’ve been together and Keiji sighs contentedly when the stiff length of it sinks into him, rubbing nicely right against his g-spot.

Keiji doesn’t anticipate he’ll last long and he doesn’t bother to waste time on pleasantries. He angles his hips so his own cock grinds into Koutarou’s muscled abdomen on each thrust and the stimulation is utterly delicious as Koutarou’s cock buries inside him again and again. Moaning, Keiji cups a hand against his own chest and pinches at a nipple, hips twitching at the spark of pleasure-pain that shoots down his spine.

“Such a good boy, puppy. The best puppy I could ever ask for,” he pants, planting his free hand on Koutarou’s stomach for balance as he starts to bounce on his cock.

He can’t get too high or else Koutarou’s cock will slide out of him, but the pressure against his sensitive inner walls is so good when he rides him like this. Keiji clenches his cunt around Koutarou’s cock and huffs out a laugh when Koutarou comes a second time, listening to him whimper as Keiji continues to fuck himself.

Just as his own pleasure is starting to build, Keiji raises himself off Koutarou’s cocklet and climbs further up his body to grind himself against Koutarou’s skin, panting as he comes in a wet, sticky squelch of slick all over his chest. He rocks his hips into him through his orgasm then slowly sinks down to lie on top of him, desperate to catch his breath for just a second.

Koutarou nuzzles into him and Keiji chuckles, turning his head to press soft kisses to his face and neck. He’s pliant and clingy and Keiji does his best to soothe him with gentle fingers in his hair and quiet, murmured assurances that he was so, so good, but ultimately he has to get them both up out of the wet spot.

Getting Koutarou into a bath is going to be impossible for a while so Keiji does his best to clean him up with a wet washcloth and then tosses it and the now soaked towels into the washing machine. He does manage to make Koutarou drink some water at least, and while he removes most of the puppy play gear to get cleaned and sterilized for the next time, he leaves the collar on for now.

Koutarou likes to sleep in his collar after a scene, especially when he goes deep.

He’s starting to come back to himself a bit by the time Keiji climbs into bed with him, accepting the bites of protein bar that Keiji feeds him piece by piece for a while before he buries his face into Keiji’s chest, refusing to eat any more.

“You were so good for me tonight, Koutarou… I’m so proud of you,” Keiji praises softly, stroking his fingers through Koutarou’s hair as he begins to shake.

He has a hard time coming down from his headspace if it’s been a while since the last one and Keiji can’t help the fresh guilt that fills him. It’s his fault that it’s been so long since their last play time together. Kissing Koutarou’s forehead, Keiji closes his eyes and huffs out a quiet sigh.

“I’m sorry I’ve been so busy lately. Master promises to be better about paying attention to when you need to play, and to stop letting work distract me from taking care of my puppy like I should be,” he murmurs, curling his arms possessively around Koutarou.

Koutarou makes a tired noise and muzzles his cheek against Keiji’s chest, looking so soft and sleepy and vulnerable that Keiji just wants to wrap him up in a blanket and hide him away from the rest of the world.

“You’re th’best Master ever, ‘Ji,” he slurs, blinking foggy gold eyes up at Keiji. “Love you… Thanks f’doin’ this f’me.”

Keiji smiles faintly and presses his lips to Koutarou’s forehead, drinking in the scent of sex and sweat that still clings to his skin.

“Love you too, Kou. Thank you for trusting me with this.”

Keiji doesn’t know how he got so lucky to have someone like Koutarou but he thanks the stars every day for the impossible joy of getting to hold him while they drift off.

It’s the best sleep Keiji’s gotten in ages.
