Choco crossed her legs, rested her chin in her palm, and gave a deep sigh, looking forward with an exasperated expression.

"Towa-sama...you know I'm a NURSE, not a veterinarian, right?"

The purple-haired devil girl seated in front of her clasped her hands together and gave her best puppy-dog eyes. "Come on, pleeeease, Choco-sensei? You're the only one I can ask right now! I came all the way to your infirmary in the underworld just to see if you could help!"

"Really? How am I the only person you can ask for help finding out what's wrong with your pet hellhound? I'm a school nurse; I've never treated an animal in my life!" She looked over to the beast sitting beside her owner, a puzzled expression on his face. "And did you have to bring him with you right now?"

Seated on the floor next to her was a massive beast sitting patiently next to his owner. He resembled a giant Doberman, about the size of a donkey. His head easily reached above Towa's and then some. His ears pointed straight up, and his coat was primarily jet black, with the hairs charred on the ends. Underneath the fur, patches of his skin glowed orange, where his body temperature was exceptionally high. As for his head, his eyes were a deep scarlet, the iris glowing. On top of the head were horns, jet black and curved backward. His tail was also unlike that of a normal dog's, being thin with a pointed, spearlike tip at the end.

Towa leaned over and hugged her hellhound. "I can't leave Kuroshi alone when he's like this! What if he ends up tearing up my place out of frustration?"

"Putting that aside, there remains the fact that I really don't know very much about animals. There have to be others much more qualified than me that you could ask."

"Well, it's not like I can take him to any regular old vet in the human world; imagine him sitting in there; everyone else would panic! And there's NO way I could go to the underworld to try and find some random hellhound trainer to figure out his problem! Those people are WAY too scary! You're the only person I know with medical experience who won't freak out at the sight of him."

"Not to be rude, but couldn't you have spent some time trying to figure out what exactly the problem was before you came to me? You're more familiar with him than I am, and if I knew, I might've been able to fix him up right away."

"Well, that's the other thing...my schedule's completely booked right now. I have to prepare for my upcoming birthday concert, record for a cover I'm putting out alongside it, and stream with Sui-chan later, not to mention the meetings and the collabs I have scheduled for the rest of the week...I'm totally swamped, and suddenly he starts acting all moody and aggressive! I really can't spare the time for him right now." Towa bowed her head down and raised her clasped hands. "Please Choco-sensei! If you can't find out what's wrong with Kuroshi and fix it, can you just look after him for a couple of days? I'll make it up to you, I promise!"

Choco closed her eyes, shook her head, and shrugged while sighing again. "Fine, fine. I'll look after him and see what I can do to help him. But I'm holding you to what you just said, alright?"

Towa jumped out of her chair and wrapped her arms around the demon nurse. "Alright! Thank you so much, Choco-sensei!" She let go and turned back to her pet hellhound, bending down a little and patting him on the head. "Alright, Kuroshi, I've got to leave you with Choco-sensei for a little while. Be a good boy, and don't cause her any trouble, alright?" He gave her an affirmative bark, and she stood back up, making her way over to the infirmary's door. "I'll keep in touch with you, Choco-sen. You're a lifesaver!" With those words, she walked out of the office, the door swinging shut behind her as her footsteps trailed away.

Choco shook her head again, looking over at Kuroshi sitting on the floor in front of her. "Your owner's a real handful, you know that, boy?" She stood up and stretched her arms before placing her hands on her hips. "Right, well, no time to waste. Let's at least try to figure out what's bothering you." She walked over to one of the medical beds, patting it and beckoning the canine. "Come on, boy, up."

Kuroshi stood up, lazily trotted over to where Choco was standing, and hopped up on the bed. She started by looking over his body, trying to remember what she knew about hellhounds from her one course on underworld biology back in her academy days. At a cursory glance, nothing looked out of place; she started by inspecting his horns. They seemed undamaged, so there were no problems there. Prying open his eyelid, she looked over the eyeball; no signs of irritation. Next up was his mouth; his teeth were clean and sharp, and his gums looked healthy. She let go of Kuroshi's head and moved down to his body, the dog giving a shake now that she no longer held him in place. As for his coat, there were no sores, parasites, or anything else out of the ordinary on his skin. His tail was alert and active, wagging around like nothing was wrong. What could possibly be the issue? Stepping away from him and walking towards her medical cabinets, Choco decided to move on to some internal inspections. "Which one was my stethoscope in again..." she muttered, bending down to rummage through one of the lower ones.

Kuroshi's head and ears perked up. In front of him was the curvy bottom of a demon woman, clad in a tight, black skirt, wiggling from side to side. Unbeknownst to Choco, she was stimulating the problem she was hoping to fix and was in for a big surprise as he hopped off the bed and began sniffing at her rear. With his large frame, he hopped up on top of her and began to hump away, Choco letting out a startled yell as he did so. "Ah! Kuroshi, what are you doing? S-stop! Off, boy, off!"

Obeying, Kuroshi relented and got off Choco's back, sitting down and giving a slight whine as he did so. The demon nurse stood up and turned around, setting her hands on her hips. "Geez, boy, what the heck was that about? It's almost like you were trying to...oh my!" Letting out a gasp as she looked up and down his body, she saw something that wasn't apparent before; a fully erect, throbbing canine penis sitting right between the hellhound's legs. Of course. The enhanced aggression and the restlessness when left alone; how could she not have seen it earlier? He was in rut.

While hellhound reproduction was something she knew less about than regular hellhound biology, Choco at least understood the basics; while the normal human world canines' reproductive cycles functioned entirely around the females' reproductive cycles, hellhounds were different. They had a system where the females would go into heat and the males into rut at around the same time, ensuring both parties would be particularly...enthusiastic about mating. In particular, the males were known to be highly dominant and aggressive during their rut cycles.

Choco put her hand to her lips, pondering what to do about this. She couldn't just leave him like this; she'd promised Towa she'd try to help fix whatever the problem was. One option was to go and find a hellhound trainer herself and try to introduce him to a female in heat, but there were several problems with that: First of all, she didn't know any hellhound trainers herself. Towa was right about one thing, they WERE somewhat intimidating people, and she'd rather not have to suddenly approach one if she could find a more straightforward way to go about this. Besides, even if she did, there's no way they'd let some random dog throw his genes into the mix and breed with one of their females; breeders were very strict about complete control over who got to be a stud for their brood bitches. Finding an acceptable partner for Kuroshi would be a near-impossible struggle. She had trouble finding a partner for herself; how was she supposed to find one for this dog?

A thought suddenly pierced through her mind, her eyes growing wide; she returned her gaze to the thick, long dick, which was twitching eagerly—a partner for Kuroshi...and a partner for herself. For years, Choco had been trying to find someone to take her, but no matter how hard she tried, she could never find the right man. There was always something wrong with him, or something wrong with her, or they just couldn't find the spark of passion between each other. She'd been with human men and demons of all shapes and sizes, but not one hit the mark. So maybe...she could try going for something a little more...out there?

"He DID get this way because of me...I could get him off with my hand, and everything could return to normal. Towa would never have to know about it. It would be all in the name of treatment, of course!" Choco mused to herself out loud, causing Kuroshi to quizzically turn his head at her, unsure if she was talking to him. Of course, she was lying to herself, and she knew it well.

Choco stepped back to the bed, her heels clacking on the hard floor as she did so. She daintily sat, looking towards Kuroshi and speaking in a softer, sweeter voice than before while patting the space next to her. "Come here, boy...let me take care of that for you, hmm?" Obeying, he jumped back onto the bed, his large frame just barely able to fit comfortably along with her. He sniffed at the woman who had piqued his arousal, licking her face in an attempt to court her. She gave a small giggle, then crawled underneath him, approaching the manhood she wanted to give a closer look.

Coming face to face with it, Choco cooed with delight seeing the thick dog dick up close. An impressive foot long at least, it was a deep crimson with its veins emanating a slight glow, the intense heat coursing through them radiating into the air. She wrapped her hand around it, and as she expected, it was hot to the touch; for a human, it'd be too hot to handle, but for a demon like herself, the heat was a welcome delight. It was also reasonably sticky and damp; the moisture in the air around it constantly evaporated, wrapping the tool in a steamy haze. She stroked it carefully, handling the entire thing, from the tapered tip at the end to the fleshy knot at the base. Each stroke made Kuroshi's cock twitch with excitement as Choco's soft, silky hand glided up and down with expert precision. While not a succubus, Choco was still very proficient in the art of sex and was proud of it. Her hand started to moisten as the steam around it condensed on her hand, causing her stroking to get slicker and slicker, faster and faster.

The combination of the intense heat in the air around Kuroshi's crotch and the masculine, bestial musk emanating off his genitals wafted into the air and, subsequently, Choco's nose. It made her dizzy, stimulating her excitement and slight shame at the fact that she was trying to get an animal off. As she became more and more aroused, she craved something more than just stroking. The deep crimson cock bobbed enticingly in front of her; maybe she could just...

In a haze of lust, Choco opened her mouth and leaned forward, directing the tip of the hellhound's cock into her mouth. She pushed her head forward, enveloping her lips around the shaft, taking more and more of it into her throat. The heat coursed throughout her oral cavity, her saliva sizzling as it made contact with the hot cock and causing even more steam to fill the air around it. She moaned around it as the taste flew across her taste buds, a strong, salty flavor that made her crave more. She dropped her hand and began to bob back and forth, twisting her head around as she sucked off a hellhound. Her tongue licked around the bottom of his dick as she slurped, aiming to please him. The depravity of what she was doing only excited her further; she was working to satisfy a friend's pet, debasing and placing herself beneath him.

The pleasure of a female's mouth activated Kuroshi's mating instincts, and he shifted his legs into a stance that gave him more control and thrust forwards, Choco letting out a surprised gurgle as more dog cock than she bargained for poked its way into her throat. He started to jerk his powerful hips back and forth, taking power over the nurse throating his cock and setting his own pace. She suppressed her gag reflex as the long, tapered dick shot in and out rapidly, the thick bulb at the base smacking against her soft, round lips each time, the lipstick she was wearing leaving traces on it. Her gaze went half-lidded as she entrusted herself to his whims, accepting that he was now in control. She focused on keeping her tongue moving, trying to stimulate his shaft as much as she could as he fucked her face. She could feel his precum leaking into her throat, the intense heat of it sliding down, providing a pleasing sensation like sipping hot chocolate.

With a mighty thrust, Kuroshi's knot suddenly pushed past Choco's lips, filling her mouth entirely as he sheathed his whole foot-long cock in her throat. Her eyes widened as she began to choke on it, unable to pull herself free. All she could see was his dark, furry underbelly smothering her face. Still acting on his instinct, Kuroshi rapidly rocked his hips against Choco's face, only able to make short, small thrusts. His jet-black, heavy balls smacked her chin with every push, drool dripping onto them. She started to feel light-headed as the male above utterly dominated her, her mouth as good as any other hole for him to fuck. Steam flowed through her body and pushed out of her nose as wet, gagging sounds filled the infirmary. Mustering up the strength, Choco gave a hard pull and finally managed to pull the knot and Kuroshi's entire penis free from her mouth. She coughed and sputtered for air for a moment, then pushed herself forward, the lack of oxygen and her intense lust still clouding her mind. At this point, she was fully engrossed with the powerful male she was servicing, no longer caring that he was an animal. The foot-long dog cock rested on her face, and acting on instinct, Choco stuck her tongue out and began to lick at the shaft, still eager to taste more.

She worked her way down, reaching the knot and swirling her tongue around it before continuing to reach the ballsack that was smacking against her face moments before. Like Kuroshi's dick, his balls were burning hot; resting them on her face, she could feel the boiling cum coursing through them, eager to breed with whatever bitch he could pump it into. She licked at one of the heavy, jet-black nuts before taking as much of it into her mouth as she could and slurping around it. Her tongue circled the surface, tasting his masculine flavor, polishing it to a sheen. Not one to leave a job half-finished, she did the same to the other of his balls, covering as much of it with her saliva as she could. To her, these were the symbol of his masculinity. They deserved to be treated with as much love and care as she could provide them. She took her tongue back into her mouth and kissed his sack lovingly, pressing her lips deep against the skin. A bright red lipstick mark was left on the surface when she pulled back. She left kisses all over his testicles, showing them all the love and appreciation she felt for the source of his seed that she hoped he would pour into her soon.

“Mmmmmm, I just can’t get enough of these…I need more~” Choco moaned loudly. She buried her face between his searing, heavy nuts and sniffed eagerly, taking in all his delicious, potent musk. She rubbed against the leathery pouch to try and get his scent marked all over her face. Unable to resist, she lolled her tongue out of her mouth and sloppily waved it around, polishing his doggy balls until they shone. Loud, messy sniffs and licks filled the room as she utterly worshiped every inch of Kuroshi’s testicles; the haze of pheromones and sweat clouded her mind, and she was elated by it. Finally, she pulled back, gasping for air after being stuffed in between the sweltering heat of a canine’s ballsack for so long. Her mouth was a mess, covered with saliva and sweat; a thin trail of the mixed fluid connected her lips and the two dangling orbs beneath him.

Choco could feel that her black, lacy panties were dripping wet with her arousal. She couldn't take any more foreplay; she needed to handle this colossal hellhound cock deep inside her. Wasting no time, she wiggled herself out from under him and stood up, quickly pulling off her black skirt, then removing her panties, leaving her smooth pussy exposed to the air. Confused about why she stopped, Kuroshi had hopped off the bed, sniffing at her; the smell of her wetness made its way into his nose and only served to arouse him further. Fully prepared, Choco set herself back on the bed, pulling her stocking-clad legs up and out, spreading them wide. She left her thick, bubbly butt hanging off the foot of the bed to give him an easier time penetrating her. She called out seductively to her hellhound lover: "Come on, boy. Mate with your bitch..."

Following the smell that had aroused him, the giant beast moved towards where Choco had placed herself and sniffed at her dripping wet pussy. A few licks of his large tongue told him everything he needed to know: in front of him was a bitch in heat, ready for mating. Kuroshi moved forward, placing his muscular hips above Choco's, lining his groin up with hers. Struggling to find purchase, his front legs moved around the bed before he settled them on top of her hips, his paws curling downwards to rest on her ass. She gasped and let out a small giggle, her legs coming together to rest above his thighs and her arms reaching up to hold his big, powerful body pressing down against her own.

Kuroshi clumsily jerked his hips, his dick randomly poking around the demon woman's pelvis, attempting to find its mark. "Hold on, boy, let me help you with that..." Choco trailed an arm, still in the sleeve of her white coat, down to the hellhound's crotch. She gripped his scorching hot cock and pointed the tapered tip into her vagina. Feeling his cock touching a woman's wetness, Kuroshi instinctively thrust forwards again, finally burying his dick inside Choco's wetness. She moaned in surprise; so much of him entered her at once, the heat radiating through her lower body. "Oh fuck, that's so big..." She reflexively clenched around his thick shaft, her instincts desperate to keep him inside her. Her first experience with not just an animal inside her, but a demon one at that, was much more unique than even she anticipated. The sensation was indescribable; she could simply feel how different his cock was from a human's or even a humanoid demon's. The consistency of the flesh, shape, and incredible heat gave her a rush she had never gotten from sex before.

And the rush she felt was only magnified when Kuroshi began to move. Wasting no time, he humped forwards quickly, eager to work on breeding the female he was buried inside. He pumped downwards hard and fast, slamming into the woman much smaller than him, the eight inches of his shaft shooting in and out of her. "Ooooh! You're really wasting no time, are you, boy?" She squeezed her arms and legs tight around his body as he pounded her cunt. She'd never felt so full before, and the scorching hotness made her demonic body even more excited; the tiny bit of pain she felt from it only enhanced her pleasure twice over. She could feel his thick knot smack against her labia with every thrust, and she knew it'd be amazing to feel him shove it inside her.

Not that it would be any time soon; one thing hellhounds certainly didn't lack was endurance. Sweet, sing-song moans escaped Choco's lungs as she passionately fucked against the dog within her deepest parts, grinding her supple cheeks against his hips. His heavy, leathery sack swung like a pendulum and slapped against her jiggling ass, again and again, the boiling seed churning within them. All that Kuroshi knew was that the hole he was fucking was soft, wet, and tight and was pleasing his malehood better than anything ever had. His claws dug into her bottom, scratching the skin and marking her flesh. Choco willingly accepted every part of his dominating lust, of course. While she did like to take control occasionally, there was nothing better for her than feeling a powerful male claim her curvy body as his by absolutely brutalizing her in bed. The fact that it was an animal doing it was even more titillating. He fucked hard and fast, seeking his own release more than her comfort, and the degrading sensation of just being used as a fuckhole for an animal aroused Choco to no end. "Holy shit, boy, you're so good! Keep going, break me, use me for your pleasure, make me belong to you!" Feeling an orgasm coming, she buried her face into his hot, broad chest and moaned into his fur. Her large breasts, still trapped within her pink shirt, squeezed up against his stomach, her erect nipples poking through the fabric. With a mind of its own, her tail wrapped itself around his thigh, doing whatever it could to keep him inside her. Finally, she came around his hot dog cock, her mind going blank as her juices soaked his penis. Her arms and legs twitched as they clung to his body, embracing him tightly, savoring every moment she felt him plunging into her pussy. Steam lifted off his throbbing crimson shaft as her arousal evaporated off the hot surface of it, making the air between them hot and moist. And in the throes of her orgasm, Kuroshi simply kept humping away at her, not noticing or caring about her body shaking from pleasure or her mind starting to crack.

Not wanting it to end in this manner, Choco managed to unfurl her limbs from the massive hellhound and gently but firmly pushed him off of her, his dick making a loud shlick noise as it withdrew from her. Getting pushed onto the floor, Kuroshi let out a sound between a loud whine and a growl, frustrated that he wasn't allowed to finish inside the woman he was feeling so good inside. Choco sat up and patted his head, her generous chest heaving up and down as she breathed heavily while coming down from the wonderful orgasm she had just had. She gave him a soft smile. "Don't worry, boy, it's not over yet...I just wanted to make things a little better for you." She turned away from him and crawled forward fully onto the bed on all fours. She flipped the back of her coat onto her back, raised her shapely rear into the air, and placed her head on the bed, fully presenting herself to the beast behind her. She seductively reached her arms back to her butt, jiggling it with her hands to try and entice him before giving it a hard slap, then spreading her cheeks wide and giving a light giggle. "Come on, Kuroshi. I'm ready for you to pump every last bit of your doggy cum inside me~" Her tail slipped between her legs, taking one of her labia and spreading it to the side, exposing her dripping wet cunt to the yet unsatisfied dog.

Her words didn't reach his brain, but her submissive pose told Kuroshi everything he needed to know. The hellhound jumped onto the bed one more time, moving forward until he stood entirely over her. One of his front paws found purchase on her shoulder, and the other firmly pressed onto her head, pushing her face into the bed beneath her. His loins jerked around, his throbbing, eager cock doing its best to find its mark before, with one lucky thrust, he poked into Choco's needy vagina. She gave a delighted gasp as she was filled up with dog cock once again, pushing deep within her as he kept her head held down beneath his paw. As this position was much more natural for him, Kuroshi again started thrusting at a breakneck pace as his breeding instinct took over.

While the first position they were in was intense, it paled in comparison to the rough copulation that occurred in this one. Living up to its name, doggy style let Kuroshi go all out on Choco's pussy, the glowing veins on his cock pulsing as he thrust in and out of her four times a second. Loud claps rang out whenever his furry hips smacked her enormous, round ass, the soft flesh squishing from the force and creating ripples across the skin. His scorching knot rubbed against her clit each time, making Choco tremble with delight at the added stimulation. As he fucked and fucked, Kuroshi growled in bestial conquest, making sure the bitch beneath him wouldn't dare try to get out of his grip. Not that she even wanted to, of course; her voice rang out with sweet and manic words of praise as the hellhound dominated her. "Yes! Oh fuck, I'd never have imagined this would feel so good, so right! Keep going, boy! Fuck your slutty demon bitch! Make me scream as you slam that wonderful dick against my womb!"

Of course, it was more for her arousal than actually trying to communicate with him, but she meant every last word she said. There was no way she could go back to having sex with humanoids after this; the feeling of being pinned down by an animal and savagely rutted was a rush she could never get anywhere else. The degrading feeling, the intensity of the sex, the heat of his cock radiating through her walls...this felt right. This was where she belonged, speared on dog dick, a paw pressing her face into the bed to remind her who owned her. Her tongue hung from her mouth as another orgasm rocked through her, her arms limp at her sides as she spasmed with ecstasy. Yet still, his scarlet red cock had no signs of slowing down, smashing into her cunt repeatedly.

One intense thrust made the pointed tip of Kuroshi's penis brush against the entrance to Choco's womb and made the front of his knot barely slip inside, shooting off sparks in her mind. Still sensitive riding off her last one, she had another mini-orgasm immediately, her back arching and her plush lips forming an "O" shape as her eyes started to roll up reflexively. And when his furry hips rolled back and slammed forward again, the same thing happened, and everything began to blur for Choco. He fucked her deeper than she ever knew she could be fucked, and it became hard to tell where one of her orgasms ended and the next began.

"Oh god, yesh! Fuck me harder wif that knot of yours! You’re better than any man I've ever had! Dominate me like a real man! Take your bish and knock her up! I luv you! I luv your big, long, heated dog cock!" Choco screamed out, her words slurring from the pleasure rocking her brain. The impact of his thrusts made her rock back and forth, and her breasts slipped out of her blouse. The round orbs smushed against the bed and her hard nipples brushed the sheets, adding another layer of stimulation to her already overloaded mind. The heat of his body pressed against her back flowed into her, making her body dripping wet with hot sweat. His singed fur was like a heated blanket pressing against her, giving her a sense of security underlying the mind-blowing pleasure.

Kuroshi's thrusts, still powerful, began to become erratic, his cock pulsing more and more. She could feel his balls tighten as they swung into her thighs. There was no mistaking it; he was getting ready to cum. Even in Choco's fuck-addled state, she could tell, and the prospect of it made her heart flutter with excitement. "Please! Shove that fat knot inshide me and cum! Unload your hot sperm into thish doggy shlut! I need every lasht drop inshide me!" Her heart-tipped tail snaked its way behind him and twirled around his, a sort of embrace as she wiggled her hips, encouraging him to finally bring things to a close. And with one final, brutally hard thrust, and a deep growl, Kuroshi pushed his wide, bulbous knot past Choco's wet labia and inside her tunnel and began to unload. Boiling semen pulsed out of his fat balls, traveling through his veiny red shaft and out his pointed tip. It poured directly into her demonic womb, heating it and flooding her eggs. A final, glorious orgasm rocked through Choco's body, the curvy nurse crying out in delight at the feeling of being seeded by her big, domineering canine lover. Every last muscle in her body twitched in euphoria, eagerly accepting every last drop of hot dog cum he released inside her. Not that she had any choice in the matter; as more and more semen filled her depths, his knot remained at the entrance, tightly sealing it and not letting a drop exit her insides.

Kuroshi jerked around as his release began, still instinctively humping at the thick ass in front of him, causing his dick to poke around Choco's insides while filling her up. The extra stimulus of his tugging around only enhanced her orgasm, giving it additional peaks of bliss. Finally, her climax died down, her body going limp as the experience left her exhausted. Yet, Kuroshi's cock continued to steadily pour hot semen into her vagina, only slowing down slightly. Acting on instinct, he began to shift around, trying to dismount from the demon nurse. He twisted his body, turning it until he was facing away from her, his penis pointed backward, still lodged inside her. His heavy balls, pulsing as they churned out his seed, rested on her ass, still battered and hot from taking so many hard thrusts from the hound. Choco's tail curled up and met his sack, the heart-shaped tip caressing it gently, encouraging him to pour out every last drop inside her. She gathered the energy to bring her arms up, crossing and resting her head on them as she spoke to the canine behind her in a sultry voice.

"Mmmm...you're pouring so much of your hot cum inside my womb...good boy, keep going. Drain those doggy balls inside me trying to knock up your bitch~" Choco said seductively, letting out a small giggle before closing her eyes, humming in contentment as she relaxed, waiting patiently for him to finish cumming. After what felt like hours but was closer to about twenty minutes, his flow stopped, Choco's womb and tunnel filled with hellhound semen, not a single space left unoccupied. His knot softening, Kuroshi gave a couple of tugs forwards before his cock popped free of the curvy woman, Choco letting out one last moan of surprised pleasure when he pulled free. Seed flowed out of her, her smooth, plush labia bright red from the heat of it and steam emanating off of the small puddle that formed. With nothing holding her up anymore, her legs finally collapsed, leaving her lying face down on the bed, her pelvis soaked with a combination of cum, sweat, and juices. She released an exasperated sigh, exhausted from the roughest, most passionate, and most pleasurable sex she'd ever had with an animal of all things. Suddenly, she felt said animal's breath on her face, Kuroshi's mouth right next to her, reaching out his large tongue and licking at her in a show of affection; it was almost like standard aftercare. Smiling warmly, she shifted onto her back, closing her eyes and opening her mouth to accept him. His tongue met hers, and she made out lovingly with the beast, twirling her tongue around his sloppily. It was red-hot like the rest of his body, but Choco still poured every bit of affection into the kiss. She pulled her head back, a trail of saliva connecting their mouths as she gazed into the slight glow of his eyes. Falling in love with a hellhound was probably the last thing she expected to happen to her today, but it was the best thing she could've asked for. He lay beside her, and his furry body warmed hers like a blanket as she cuddled up. They both started to doze off, tired and content in one another's presence. One last thing went through Choco's mind as she closed her eyes and smiled dreamily; she would definitely ask Towa if she could "look after" Kuroshi again in the future.

SEVERAL MONTHS LATER

Towa thumbed through her phone, rechecking her messages while her other hand tightly held a leash attached to Kuroshi's collar. This was the place, right? Everything seemed correct; this was Choco's home in the underworld. She didn't talk much about her family, but it seemed they held a surprising amount of power and wealth down here, enough for her to have a whole place to herself. Choco usually stayed in the human world for streaming, but she'd taken a sudden break a while back; she didn't explain why, but nobody was going to put pressure on her to explain. She had kept in touch with Towa, though, so she knew a little about what was new in her life. Towa put her phone away and reached out to ring the doorbell, a cacophony of high-pitched yips and barks ringing out when she did so.

A few moments later, the door opened, and there Choco was, out of her lab coat and smiling warmly at her. Five hellhound pups were at her feet, excitedly jumping around and wagging their tails at the new visitor they hadn't seen before. "Towa-sama! You're here; come in!" Towa stepped inside, accepting her invitation, bringing Kuroshi in with her. She took off her shoes and left them at the front, following Choco to her living room and tugging Kuroshi along, trying to stop him from getting distracted by the puppies jumping around and on him, trying to get him to play with them. Making it to the living room, they sat down, Choco on her favorite chair and Towa on the couch, finally releasing Kuroshi and letting him freely play around with the pups, who were happily hopping around and playfully yipping in excitement. Choco laughed heartily at the spectacle, and Towa smiled slightly before looking back to the nurse.

"Thanks for agreeing to look after Kuroshi again, Choco-sensei. I know you're probably a bit busy taking care of these little guys, but my schedule just got packed full, and he was starting to act strange again..."

"No problem, Towa-sama! After last time, I said you could leave him with me any time, and I meant it! There's always room for more in my house, after all." She smiled brightly, one of the puppies hopping up on her lap.

"Still, I never expected you to have gone and bought a hellhound of your own, let alone five puppies. I know how much you value your rest, and even one of these guys is a fair bit of work. What happened?"

Choco reached down and petted the puppy in her lap, jumping up at her chest and trying to lick her face. "Well, after I spent that time with Kuroshi, it made me realize I've been quite lonely for a while and needed a companion. Lucky for me, the first breeder I went to had a litter for sale, a bunch of mutts he hadn't planned for, and they all warmed up to me immediately. I couldn't bear to separate any of them from each other, so I took them all home with me, and I've never made a better decision!"

Towa let out a small "hm," looking at Choco closely as she played around with the pup on her thighs. It seemed plausible enough, but it was strange. Was Kuroshi really that charismatic to make this woman who loved her rest and time to herself suddenly commit to something this time-consuming? He was a nice boy, for sure, but he never seemed like a one-of-a-kind wonder dog that would charm someone this much.

Suddenly, a small detail caught Towa's eye. She hadn't seen it until now, and it puzzled her immensely. It had to just be a coincidence, right? But still...

"Hey, Choco-sensei? One more question."

Choco paused, looking up at Towa expectantly. "Yes, Towa-sama?"

"The puppies' horns and tails...don't you think...they look a lot like yours?"
