a dog's tail is its greatest asset

Summary:

Hatsune has an idea for how she can be even more puppy-like. Sakiko helps.

Notes:

This was written before episode 10 aired, and then episode 11 slapped me in the face. After episode 13, I went back and let me tell you, it is not simply a matter of changing all instances of 'Uika' to 'Hatsune'. If you see any inconsistency in the characterisation, that's because I had a predetermined idea in mind, but then had to alter it so that it fits Sakiko and Hatsune's ending dynamic. Taught me to never write for an ongoing series ever again.

And yes, I still ship them after episode 11. If you dislike that but have clicked on this title nonetheless, I don't know what to tell you anymore.

Work Text:

“Hatsune, sit.”

At once, Hatsune squats down, sitting on the balls of her heels. She does it with such speed that Sakiko has to wonder if she doesn’t get whiplash from it. Her paws are placed together neatly in front of her, and her eyes are trained upwards — towards Sakiko’s — wide and expectant.

“Good girl,” Sakiko smiles sultrily, and delights in the subtle, but visible shiver that runs through the blonde. She takes a step forward, watching the way Hatsune’s pupils shift to follow hers, the way the muscles of her neck strain to hold the position. 

Sakiko cups Hatsune’s cheeks with both of her hands. Her touches are feather-light as they trail downwards, following the pronounced ridges of Hatsune’s jaw to her neck. The muscles bob under her fingers, once, as if something has been swallowed — though Hatsune’s expression betrays nothing. Just rapt attention, and a staunch dedication.

“You’re a good girl, aren’t you?” At that, Hatsune’s face lights up with just the brightest smile. She gives a soft bark and nods enthusiastically, even bouncing a little on her hindlegs. Sakiko laughs — a light, fond sound. If Hatsune’s tail were real, it would most likely be wagging right now. “Yes, you are. Yes, you are.” She uses her thumbs to squish Hatsune’s cheeks together, rubbing them around. Hatsune’s eyelids flutter, a pleased, goofy smile spreading across her face.

Sakiko moves her attention downwards. Her fingertips continue, leisurely, to Hatsune’s bare shoulders — catching a little on her collar on the way, and feeling Hatsune’s breath hitch in response — then down her chest. Hatsune’s eyes move to follow them, a subconscious action.

“No, Hatsune, keep your eyes on me,” Sakiko takes off a hand to gently grab Hatsune’s chin and guide her gaze back to hers. Hatsune whines, but complies. Sakiko gives her a pat on the cheek in encouragement, before returning to her task. To make things easier for her at least, she kneels down, lowering herself to Hatsune’s eye level. Like this, Sakiko still towers over her large, human-sized puppy, but Hatsune no longer has to crane her neck to meet Sakiko’s eyes. 

Hatsune’s naked body runs scaldingly hot under Sakiko’s touch as it traces the curve of her chest, almost like the golden retriever she so resembles. Sakiko gently takes a handful of her boobs, enjoying the way the warmth and the softness fill her palms. Hatsune keeps her breathing steady as Sakiko takes her time playing with them, massaging them, really feeling out their shapes — though Sakiko thinks she hears the quietest intake of breath as she experimentally presses her thumbs into Hatsune’s cute, pink nipples and rolls them around. A glance up at Hatsune’s face grants her a most amusing sight — Hatsune’s lips pressed into a thin line, the slightest crease between her eyebrows, and a sort of glazed look over her eyes as she struggles to focus her gaze ahead, and not look down as instructed.

“How do you feel, girl? Do you enjoy being touched like this?” Sakiko prompts. 

Hatsune’s eyes snap back into focus, and she is quick to let out a happy “Arf!”. Sakiko smiles. 

“If you like it, don’t be afraid to make a little noise.” She leans in — close enough to feel the heat of Hatsune’s glowing cheeks brush her own — and whispers into Hatsune’s ears. “I like hearing the little whimpers you make.”

She punctuates that with a possessive squeeze. She feels, rather than see, the full-body shudder that wracks Hatsune… followed by the high-pitched whimper that she has been waiting for, in the same voice that Hatsune uses to captivate thousands of people as Uika and sing the songs she composes so beautifully. 

Sakiko suppresses a shiver herself. Hatsune’s voice never fails to have that effect on her — no matter on stage, or in the bedroom.

“Such a beautiful girl,” Sakiko murmurs as she pulls back, the performed sweetness of her words tinted with a hint of genuine affection. Indeed, it’s hard to believe at times that such a beautiful, talented woman, an idol so widely revered like Hatsune can hold such devotion to someone like her, who has caused everyone so much harm. Sakiko tries not to think too hard about it these days — Hatsune herself is not without sin, and they have made a vow to forget — but the thought still sneaks up on Sakiko from time to time. “What did I ever do to deserve you?”

The look Hatsune is giving her is already heavy, swimming with lust, but at that, something seems to shift within those darkened purple eyes. Suddenly, she leans forward, her tongue on Sakiko’s neck catching her by surprise. Sakiko gasps, falling back on her hands, Hatsune’s full weight bearing on her shoulders from where her paws have come to rest on.

The weight is too much. Sakiko’s arms buckle under it, and they topple to the floor, Hatsune on top of her. Hatsune’s lips are latched tight onto her, leaving open-mouthed kisses on where she knows Sakiko is most sensitive. Involuntarily, Sakiko lets slip a few noises. 

“No, Hatsune, stop,” she tries to admonish, but it’s hard to sound stern with Hatsune’s hot, panting breath so close to her ear. Something wet wraps around the lobe, and Sakiko moans at the arousal that shoots straight down her core.

“Hatsune…” Sakiko breathes out, feeling her will slipping as the haze of lust slowly comes over her. Wait, no, she’s supposed to discipline her pet. With the last dredge of her self-control, she gropes for Hatsune’s collar under her golden mane, and tugs with just enough force for it to be felt. “No, stop! Bad girl!”

The effect is immediate. Hatsune lifts off her and scrambles back. The loss of her body heat is a regrettable one, but the cool air gives Sakiko back her clarity. Sakiko gives herself a moment to catch her breath, then looks down.

Hatsune looks extremely guilty. Her head is down, her shoulders hunched in on herself. She was glancing up at Sakiko through beneath her bangs, but the moment Sakiko meets her eyes, they dart down to her paws.

Sakiko sighs. It’s so hard to stay — or act — mad at her, but she must. “Hatsune, you know you’re supposed to stay still,” she chides, putting on a frown.

Hatsune whines, a distraught, pitiful sound. It strikes Sakiko’s empathy deep in its core, but she stays resolute. Although… she can’t help but let her gaze soften a little. “It’s okay. It’s not a big problem.” Sakiko sits up, and crawls towards her puppy. She takes her paws and brings them up between them as she says. “You’ll just have to sit through one small punishment for me, okay?”

That gentle tone would never work with Nyamu — who enjoys acting like a brat far too much. Hatsune, on the other hand, only nods and gives a small, shameful ‘woof’, head still down.

Sakiko smiles and pats her head, between her floppy, cotton puppy ears. Then she reaches behind her and grabs the remote. Hatsune jolts slightly when the plug attached to the tail inside her starts vibrating, but apart from a small whimper, she keeps still. Sakiko stands up.

“Come here, girl.”

Sakiko moves to the bed, drawing her legs up to kneel at the head. She pats the space in front of her invitingly. Hatsune crawls onto the bed on all four with practiced ease — only stumbling a little from squatting for so long.

“Can you sit back for me?” 

Hatsune tilts her head in a perfect imitation of a confused puppy, but then her eyes widen. Her expression is one of visible apprehension. Despite that, under Sakiko’s pinning stare, she slowly leans backwards.

Sakiko leans forward at the same time, helping to guide her movement. Hatsune lets out another whimper as her backside hits the surface of the bed, eyes screwed shut — the previously loosely inserted plug fully seated inside her. “Shhhhh,” Sakiko gently shushes her, one hand stroking her mane and one hand placing on her shoulder, coaxing her to lean back on her arms. Hatsune is acting terribly clingy about it — her paws keep clinging onto Sakiko’s sleeves, trembling like a terrified puppy about to receive her shot at the vet. “You’re okay. It’s okay. You’re okay.” 

Not that she blames Hatsune. This plug is several sizes up from the girth of the toy that she’s normally used to. Still, for someone who is so hesitant about trying new things, the one who brought up wanting to try a bigger toy was Hatsune in the first place, much to Sakiko’s surprise. Perhaps it has something to do with Mutsumi’s influence — who’s introduced Sakiko to a plethora of implements invented for adult pleasure that she didn’t even know existed — but if Hatsune won’t tell, Sakiko won’t ask.

If it’s something Hatsune wants for herself, Sakiko is more than happy to grant it.

Eventually, Hatsune’s dead grip on Sakiko slackens. Sakiko keeps a hand on her bicep as she gingerly lets herself fall back on her arms, squirming around a little on the toy. Sakiko waits a moment for her to settle down, find a comfortable position. She waits for her to give the signal that she wants to stop. Hatsune opens her eyes to give Sakiko a watery look, but — after a shaky exhale — she gives a tiny nod.

Sakiko lets out a breath she didn’t know she was holding. 

Like this, the entirety of Hatsune’s gorgeous body is presented to her. With her shoulders bent back, her plump, supple breasts are in full view — swollen, cherry-coloured nipples standing out on fair skin. Her smooth, cushy and invitingly pettable belly rises and falls with slightly laboured breaths, glinting with a subtle sheen of perspiration. And between those parted, subtly muscular thighs — Sakiko gulps — Hatsune's sex stands at half-mast, tantalising, a few drops of milky precum already leaking out of the pink tip.

“You look… simply delectable,” she murmurs, breathless and candid. 

Hatsune flushes to the tip of her ears. Her maw gapes, a stutter on the tip of her tongue, before she seemingly remembers that she’s not supposed to speak and just freezes. She finally settles for an embarrassed whine instead.

Seeing that makes Sakiko giggle, her tension dispelled. Her hand hovers over her prize — though just before she makes contact, she pauses, looking up at her puppy’s expectant face. “May I?”

She already knows the answer, but there is a certain cuteness in how quickly and eagerly Hatsune nods, eyes blown wide and a “Yes!” barely held back behind pursed lips. Just the reaction she’s expected to see.

Her puppy’s length scorches Sakiko’s hands just like the rest of her, practically pulsating with need. Just from the first touch, Hatsune is already whimpering — reflexively shifting away from it, and then letting out another noise as the plug grinds against a new spot inside her. “Poor girl, already so sensitive,” Sakiko coos, even though she keeps her eyes on the arousal in front of her, showing no sign of stopping her teasing, maddening caress down its length. “Have I not been taking proper care of you?”

Hatsune shakes her head vigorously, “arf”-ing in denial. Sakiko smiles at her, guiltless. “I’m glad.” Hatsune keens sharply as Sakiko pushes her thumb into her slit and rubs. There’s a surge — even more pre dribbles down Sakiko’s knuckles. “I love when you enjoy yourself, Hatsune. Just hold on for me, okay?”

Hatsune nods, even as she’s shaking. Sakiko rewards her with a kiss to her forehead.

And oh, hold on Hatsune does. She twitches, and squirms, and struggles to stay upright as Sakiko continues to stroke her, an endless litany of pants and whines pouring out of her lips. Sakiko presses a kiss to the crease between her eyebrows, the tears at the corner of her eyes, her nose, the corner of her mouth. She captures her lips in a deep kiss, drinking in those sweet moans that are like honey to her ears — and feels one of Hatsune’s paws come up to grab onto the back of her neck, rough and frantic, pulling her closer but also hanging onto her as if trying to ground herself.

They’re both a little breathless as they pull away. Sakiko does that particular motion over the frenulum that Hatsune likes, making her jerk and yelp. 

“I don’t remember giving you permission to do that,” Sakiko smirks. Hatsune looks at her with big, pleading, wet puppy eyes, and Sakiko feels herself this close to caving, but pulls herself back at the last second. “No, girl, a punishment is a punishment. I’m sorry.” She lets go. The long, distressed wail that Hatsune vocalises in response is painful against her determination — and if she were any less familiar with it than she is, she would have lost.

She grabs the remote for the plug again, upping the vibration by one level. Hatsune jumps again, claws digging into the sheet and head bowing as she desperately swallows a whimper. 

Still out of breath, Sakiko keeps the remote in hand as she lays back against the headboard, unfolding her legs. It’s only as her head meets the pillow she’s propped up that she notices how… dizzy she feels. When has it gotten so hot in here? A healthy amount of sweat has collected under her collar — which she quickly unbuttons. She can feel dampness under her hairline, the streaking droplet cool against her burning cheeks. And the wetness in her core— Sakiko bites her lips.

She’d prefer to play with Hatsune a little more, but maybe that can be shortened a bit.

“Hatsune.” She gestures with her other hand. “Help me out of this skirt, won’t you?”

Hatsune’s head snaps up, and she all but scrambles forward. She pauses as she hovers over Sakiko’s waist, glancing up to look at her from under her bangs.

Sakikos’s breath catches in her throat as slowly, slowly, Hatsune lowers on her hands and knees, and mouths at her waistband. The soft, cloud-like touch of her lips as they brush against Sakiko’s navel — so close, so close — sparks a flame that lights Sakiko’s entire body on fire. It’s a struggle now more than ever to not lose herself in the dark, low look Hatsune is fixing her with as she pulls her skirt down with her teeth, inch by inch — the desire within those smouldering purple eyes seemingly a void without end.

She fails to notice when Hatsune was done with her bottom clothing, only comes back to her senses when Hatsune’s face is suddenly inches away from hers. The blonde leans down and noses at the top button of her shirt, silently asking.

Sakiko huffs. “Silly girl, you can’t take that off with your mouth.” Hatsune’s pouty expression and subsequent bark seem to say “try me”, but Sakiko ignores her in favour of unbuttoning her shirt the rest of the way herself. Her hands shake a little — she tries not to let the other see how affected she is already. There’s a better use for Hatsune’s mouth elsewhere, anyway.

Her shirt and bra joins the pile of discarded clothes on the floor. The moment she finishes taking her top off, Hatsune dives for her neck, but is stopped by Sakiko’s hand on her mouth.

“Slow down, girl, what did I say?” Hatsune growls and licks her palm. Sakiko expected that, but for performance’s sake, she puts on a mock scowl anyway. “Naughty girl. If you don’t stop acting out, I’m going to have to send you back into your cage. You don’t want that now, do you?”

Hatsune whines and taps her paws agitatedly, but she does retreat. Sakiko holds her back with hands on her cheeks before she can retreat all the way, meeting her gaze dead-on as she commands.

“You’re not allowed to cum before I do, understand?”

Hatsune visibly swallows, and nods. Sakiko releases her.

The cool air against her exposed centre serves as a reminder of how drenched she is. Sakiko cannot help but shiver as it is replaced by Hatsune’s warm breath, her core throbbing in anticipation to the barest of stimuli. She catches Hatsune giving her that low look one last time, before diving in.

Even after bracing herself, Sakiko still gasps when Hatsune’s tongue dips between her folds. Despite her undeniable hunger, the blonde shows admirable consideration, trying to build Sakiko up to it first with small, light flicks of the tip of her tongue. Not that Sakiko doesn’t appreciate it, but that languid pace — when she’s this wet already — quickly becomes its own kind of torture. Impatiently, she threads a grip into Hatsune’s golden mane and grinds back against her face — and is rewarded with a surprised growl and more intense licking instantly from the puppy girl, who promptly abandons all restraint to give Sakiko those heavy, full-length strokes that have her throwing her head back and moaning out.

“Ah— yes, that’s it… good girl…” Sakiko pants between moans. It only seems to spur the blonde on more.

Hatsune’s claws dig into her inner thighs, a strong grip that bares all of Sakiko to her while she loses herself in her taste. She laps, and kisses, and sucks, savouring the meal in front of her with all the fervour of a follower who has been granted a feast from God. Sakiko’s grip on Hatsune’s fur tightens, her toes curling on the sheet unwittingly, the pressure inside her swiftly building up to a level that heralds a fast approaching orgasm, with how well Hatsune handles her. 

Perhaps a little too fast, even. Hatsune’s tongue works her like she’d die if Sakiko doesn’t cum soon. Is she trying to bring her to the edge as fast as possible? This was not meant to be an easy punishment. Sakiko refuses to let her pet outdo her.

Sakiko finds, and clicks the vibrator to the strongest level.

Hatsune’s tongue stutters against her — though even that feels strangely good. Her fangs briefly graze Sakiko’s lips as her forearms lose purchase and she falls face-down onto the bed and cries out, breathing heavily. For a moment, it feels like Hatsune has collapsed — her legs trembling weakly, her arms struggling to raise herself back up. 

“Come on, girl, just a little more,” Sakiko says, also panting. Hatsune only groans pathetically in response. Sakiko wonders for one stomach-sinking moment if she’s gone too far. “Hatsune?”

The hand that rests on Hatsune’s head slides over to take her hand. Sakiko lets her fingers rest loosely on Hatsune’s palm, waiting for the signal.

After a moment, Hatsune squeezes her fingers.

Sakiko breathes a sigh of relief. She is about to withdraw her hand when Hatsune’s grip tightens. Understanding the message, Sakiko lets Hatsune hold onto her hand as she breathes, until she finally manages to pull herself up — still trembling, still breathing heavily. Her legs are squeezed together, Sakiko notices, quivering in her valiant effort not to cum.

Hatsune’s tunnel vision on her vulva suggests that she’s dying to go back in, but even through those thick, messy bangs, Sakiko can see her pupils struggling to focus. She lets go of Hatsune’s hand, only to touch it to her cheek and redirect her gaze to hers. 

“Good girl,” she praises, caressing Hatsune’s cheek with her thumb, wiping away some of her own mess plastered all over her loyal puppy’s face. She reaches over to scratch soothingly at the dip behind Hatsune’s ear — her real one, not the puppy ears she wears. “You’ve been doing so well, Hatsune. Just a little more, okay?”

Hatsune’s eyes sparkle with unbridled joy and tears, some of them falling as she closes her eyes and leans into the touch. She seems to have recovered her zeal by the time Sakiko pulls back and she opens her eyes again, letting out a soft but enthusiastic bark.

The heat simmering inside Sakiko has admittedly died down a little from the brief pause, though Hatsune doesn’t seem to have any problem stoking it right back up. It must be a kind of talent in and of itself for Hatsune to know how to work Sakiko up and have her gasping and moaning again in no time — because really, this is just unfair. Her beloved pet knows her so well, knows her inner rhythm, knows exactly where to apply a little more pressure with her tongue to make her see stars. Occasionally, her movement stumbles — or she moans, either from the continuous stimulation inside her own walls or from Sakiko’s tug on her scalp — but it’s those inconsistencies that catch Sakiko off-guard and make her toes curl every time.

The warm tingling of her climax is upon her before she knows it, and this time she lets it happen. “C-Cumming,” is all she manages before the powerful ripples of mind-numbing pleasure wash over her, leaving her blank to the world for what feels like minutes on end.

When she comes to, she hears whimpers.

Her eyes, though dazed, snap open. “Hatsune,” she pants, not having even the strength to lift her head and look down. “Come here.”

At once, she’s pressed into the bed by the weight of one big, needy puppy girl, enveloped in her heat and sweaty embrace, which Sakiko returns. “S-Saki-chan,” Hatsune whimpers, rutting mindlessly against whatever part of Sakiko she can reach. “Please… I wanna cum…”

“Where do you want me?” Sakiko asks.

“I-Inside— please, Saki—”

Sakiko hurriedly switches off the vibrator, grabs the tail and carefully eases it out — though it’s hard to tell from Hatsune’s pained whines if the motion is hurting her or if she’s just been edged to the point of wanting to explode. The blonde shivers when the plug finally exits her with a squelch, then moans loudly when Sakiko immediately replaces it with her own fingers, easily plunging two of them to the hilt from how well-lubed she already is.

Just a few firm, centric circles on her prostate and Hatsune is shuddering and coming undone above her, her back arching off Sakiko before becoming boneless. 

Slowly pulling her fingers out, Sakiko heaves a deep sigh of contentment, and allows the afterglow to hang over them for a long moment. 

It’s quiet — the only thing she can hear is their breathing together. The others are all out, there’s no sound coming from any other part of the house. Sakiko feels like her senses have come back enough for her to perceive her surroundings again — though she doesn’t really want to. Not when she can let her world stay narrowed to this bed, to the woman breathing peacefully on her chest, the warmth of their love confining them to this moment for however long the scent stays and till the proof fades.

“........ve you….”

Sakiko blinks, looking down at her exhausted puppy. “Hm? Did you say something?”

Hatsune’s eyes are already half-closed, and her voice is slurring a little as she repeats. “I love you, Saki-chan…” She curls up further against Sakiko, her breath warm on the side of Sakiko’s neck. “I’ve wanted to tell you that the whole time…”

Sakiko feels herself smile. Gently, she presses a kiss to the crown of her head. “I love you, too.”

Hatsune blinks sleepily. “Really…?”

Sakiko giggles. Silly, sensitive Hatsune, always looking for affirmation for anything and everything — even when she’s half passing out. ”Yes, really.” She lets her head fall back on the pillow, while her hand continues to stroke Hatsune’s hair. She hears the other let out a contented hum, before going quiet once again, filling the air with the soft, comforting sound of her breathing. 

It’s perfect. Sakiko doesn’t want to wake up from this, ever. 

After a while, though, an urge rises such that she really wants to clean up the sticky mess down there so they can cuddle properly.

“Hatsune,” Sakiko looks down. Hatsune’s eyes are closed. “We should clean up.”

Hatsune’s only response is to nuzzle into her neck and mumble. “Mmm… five more minutes…”

“Hatsune,” Sakiko frowns, trying to put a little more authority into her voice. No response. “Hatsune, come on, we can cuddle after we clean up.”

There’s a soft snore. Incredulously, Sakiko pokes her cheek. No reaction at all. She’s out cold.

Sakiko sighs, plopping back down. Perhaps Hatsune will wake up before the others come back. Or, in case she doesn’t, hopefully by that time, Sakiko will have regained enough strength to pry herself out from under the heavy dog girl and clean up hersel—

There’s a knock, then the door opens.

“Excuse me, Sakiko-san, have you seen—”

Sakiko comes face to face with none other than one Yahata Umiri, walking into the room with her bass still strapped on her back. She stops dead in her track as she takes in the other two in the room — her eyes going from the trapped Sakiko, to the sleeping Hatsune, to the tail plug off to the side.

A beat.

Sakiko feels compelled to say something, but before she can, Umiri speaks first, in her typical nonchalant, albeit mildly interested tone.

“New toy? That’s great. How about trying that with me next time?”
