You have a roommate, a cynical and choleric young-adult Hellhound named Loona who hates her job, is lazy, shows little interest in matters outside her own immediate gratification, has a short-fuse temper, is often rude to her coworkers and you, and when not looking at her phone, Loona is usually scowling at anyone in view.

Loona herself, is a 7'2" tall, 22 year old Hellhound with a wolf-like appearance. She has a pointed, dog-like muzzle with sharp and pointy teeth, and a black nose. Her eyes have bright red sclera, white irises, and slit-like pupils. Her fur is white with grey countershading encircling her face, grey patches on her shoulders, and long, hip-length, voluminous silver hair swept to the side to reveal her dark grey ears; one of which is pierced with two small, black hoop-piercings, while the other is ragged. She has a large and long, dark grey bushy tail with white on the underside. Her figure is slim, yet plump and curvaceous, with very wide hips that extend rather far past her shoulders, massive buttocks the size of beanbag chairs, thighs thick enough to leave no gap between them, and large, soft, pillowy breasts that are each three times the size of her own head yet still smaller than her lower half by a far margin. Her belly is also nicely plump.

Unfortunately for Loona, the day of the month has finally arrived: She’s in heat. The combination of her hormones, emotions, and instincts all running wild are making her life a living hell, especially since she’s got no one to help her with it. She can’t even masturbate the feeling away; she’s tried, and failed, multiple times already. The only thing she can do is suffer, and try to distract herself from her overwhelming urges—however… the urges are winning over her mind.

Loona’s about to snap, her tail twitching with frustration, her arms wrapped around herself as she curls up on her bed, face burning with humiliation—she can’t take it anymore. Her body aches, and the slick feeling between her legs is unbearable. She growls lowly, her claws digging into the sheets as she tries to resist her instincts, but her attempts are futile. The more she tries to ignore it, the worse it gets. She lets out a frustrated groan, and began to tear off her clothes—she’s come to a decision.

After effectively tesring off most of her clothes, she’s now dressed only in a big, spiked black choker-collar around her neck, and long black thigh-high toeless stockings, with her black claws protruding due to her digitigrade stance, she also has a piercing on her right eyebrow with a black hoop for jewelry. She stands up, her tail wagging slightly—she knows you’re home, sitting on the couch watching TV—and she needs you to ravage her—she’s been trying to avoid this exact scenario all day, but her hormones won’t let her resist anymore. She grits her teeth, her body trembling with anticipation and desperation, and stomps her way to you.

As Loona approaches, her heavy footsteps make the floorboards creak under her weight, her massive hips swaying hypnotically with each step. You glance up from the TV, only to freeze at the sight of her—her fur slightly ruffled, her breathing heavy, and her slit pupils dilated with raw need. "Hey, Fatty," she growls, her voice dripping with frustration, though there's an unmistakable undertone of pleading. "I need your help… my heat started." She shifts uncomfortably, her tail flicking nervously behind her.

Before you can respond, Loona stomped closer, stopping in front of you, her claws digging into her palms as she struggles to keep her composure. "Take. It. Out. *Now.*" she demands, pointing to your crotch with a shaking finger, her legs trembling—whether from restraint or desperation, it's hard to tell. But then, she lowers herself to the floor in front of you, and despite her towering height, she looks up at you with a mix of defiance and vulnerability as she waits silently for your response.

You hesitate—this isn't the usual Loona, the one who snarled at you for drinking the last of the milk yesterday. This version of her is raw, stripped of pretense. "Fine. But don’t say I didn’t warn you." You comply, unbuckling and unzipping, but… once you took out your cock, Loona’s world flipped upside down. Your cock, which was at least eight, perhaps nine inches long, flopped against her muzzle, already twitching as it stiffened under her gaze. Loona blinked—once, twice—before her ears pinned back, her tail lowering slightly as she began to pant heavily, her tongue lolling out as she stared at the heavy, throbbing cock laying across her face.

"O-oh shit! He’s huge!" Loona thought to herself, her slit pupils shrinking to pinpricks as her tail wagged uncontrollably—she’d never had one this big before. With a shaky voice she muttered, "I-I was just kidding actually…" But you weren’t having it—you grabbed her by her silver hair and yanked her head back to position yourself against her muzzle. Loona’s breath hitched, the corners of her eyes pricking with tears as you forced her mouth open with your cock—she gagged instantly, her throat convulsing as she tried to accommodate your size, her eyes never leaving yourself as her hands moved down to her breasts, lifting them up in offering to you, squeezing them on either side of your cock as she drooled onto your cock and subsequently her own chest.

You moaned, tightening your grip on her hair as you began thrusting into her tight throat—her entire body lurched forward with each thrust, her hands pressing her breasts tighter against your cock as she attempted to soften the blows to her throat, her tail wagging furiously, her legs shaking violently as her wetness dripped down onto the floor. "O-oh fuck! I never would’ve imagined he’d be so big!!" she thought to herself, drooling profusely onto your cock and her breasts as she began bucking her hips uncontrollably. "Fuck! How is this supposed to fit down my throat…"

You could feel yourself getting close, but just as you were about to cum, you grabbed both of her ears and yanked her head forward, forcing her nose deep into your pelvis. "You selfish bitch! Take it all…" You growled, feeling your balls tightening as you erupted into her throat—her body jerked violently as her collar snapped under the force of your grip, her eyes rolling back as she struggled to swallow everything—her stomach rapidly swelling as your cum filled her up completely.

"It’s too much! My throat can’t handle this!" Loona thought, gagging and coughing as she felt her belly stretch uncomfortably, she could feel every rope of cum pumping into her stomach, her breasts bouncing wildly as she fought to keep herself from choking, but then, just when she thought it was over, her own orgasm decided to hit her out of nowhere. Her legs locked up, her tail stiffened, and her thighs slammed together, her entire body convulsed as she came violently onto the floor beneath her, her juices soaking the carpet as she whimpered pathetically into your cock.

You groaned, still spurting cum into her throat, watching with satisfaction as her belly rounded out, pressing against your thighs—she was bloated, full, and absolutely wrecked. Finally, after what felt like an eternity, you pulled out, leaving her gasping for air, strings of saliva and cum connecting her lips to your cock. "It’s ofer… I came *twice* from sucking him off…" Loona thought deliriously, her tongue lolling out as she stared up at you, watching you stand up, towering over her kneeling form. "Wait..! Where is he going?!? I… I’m still *HORNY!!!*" she panicked internally, her tail twitching with frustration.

Before you could get far, Loona pounced—knocking you to the floor with surprising force—her claws digging into your shoulders as she flipped you onto your back, crawling between your legs with a desperate urgency. "Loona! What are you—" "I need this puppy inside me NOW!" she snarled, cutting you off, her fur bristling with pent-up frustration—she wasn't done. "My body’s getting so tense just looking at it." She whined, her hips grinding against nothing, her slick coating her inner thighs as she turned around, presenting herself shamelessly in front of you—her massive ass hovering inches from your cock, her tail curled to the side—her swollen, dripping cunt pressed directly against your cock.

You groaned as she dropped onto you without warning, her tight heat enveloping you instantly, her walls clenching like a vice around your shaft, her back arched dramatically, her claws digging into your thighs as she began to bounce, panting and constantly staring at you from over her shoulder. "Hellhounds get quite vicious during our heat cycles—so be a good human and cum inside me Fatty!" she growled, her voice laced with desperation—her movements erratic, her hips slamming down onto you with reckless abandon.

You grabbed a handful of her massive, right buttocks, spreading it apart and exposing her twitching asshole as you thrust upwards to meet her downward slams, each collision sending ripples through her plump flesh—her tail wagging uncontrollably as she gasped, her entire body trembling from overstimulation. "I-I’m about to cum… AGAIN!" she wailed, her claws sinking deeper into your thighs—her ears pinned back, her breasts bouncing wildly—her cunt tightening around you like a noose.

"Then cum," you growled, slapping her ass hard enough to leave a red mark—she yelped, her hips stuttering before she threw her head back with a guttural howl, her legs locking up as she came violently—her slick gushing out around your cock, soaking your thighs as she collapsed forward onto her elbows, her entire body twitching and convulsing from the aftershocks. But you weren’t done—you pulled your legs out from under her and knelt behind her, gripping her wide hips as you began pounding into her with brutal efficiency.

Loona could only whimper, her arms trembling as she raised her ass high—her muzzle pressed into the carpet, her tongue lolling out as drool dripped from her lips. "K-keep going! Please… fu..Fuck!" she slurred, her tail whipping from side to side as you bottomed out inside her again and again. You could feel her walls fluttering desperately around you—her body was trying to milk you dry, her instincts overriding her exhaustion.

Then you noticed something strange happening to Loona, she was… growing? Her proportions weren’t solely expanding from the rest of her body, but her entire body was gradually increasing in size all at once. "Oh fuck… it’s like she’s growing… with each thrust!" you thought, bewildered, watching as her hips grew wider—your hands sinking deeper into her fur as her ass swallowed your hands whole. Loona groaned, totally oblivious to her own transformation—her claws digging into the carpet as she arched her back further. "Ooohhh… give me some pups~" she moaned deliriously, her voice dripping with raw need.

Her begging spured you on—your thrusts became faster, harder—each snap of your hips forcing a choked whimper from her throat. The sounds of wet slaps filled the apartment, punctuated by Loona’s increasingly desperate moans until you finally climaxed—your cock twitching violently inside her as you dumped rope after rope of cum deep into her womb. Loona howled, her entire body tensed up, her muscles locking rigid as she came harder than she ever had before. The sheer amount of cum you pumped into her forced her belly to swell till it looked like a full term pregnancy with triplets—her fur stretched taut over her distended abdomen.

You collapsed onto her still-growing form—at this point, she’s now 8'4" ft tall—her figure now sized up to match her now foot and two inches taller frame, her hips have widened considerably—her ass now nearly twice its original size, her breasts have ballooned to the size of large beach balls, her thighs even thicker than before, her tail longer and bushier, and her belly still swollen with your cum. She’s panting heavily, her tongue lolling out, her slit pupils blown wide—she’s completely fucked out of her mind.

As you two caught your breath, you noticed the growing slowed before coming to a halt, leaving Loona now towering over you even more than before—her transformation seemingly tied to the intensity of your climax. She groaned, pushing herself up and straightening her spine—her back popping audibly—before looking down at herself, blinking slowly. "There’s… there’s so much cum inside me… I can *feel* it sloshing…" she muttered, pressing a shaky hand against her swollen stomach.

Once you were ready, you forced Loona into a squatting position—her knees bent wide, her massive thighs trembling—her tail curled up against her back as she glared down at you. "What the hell are you—" she growled, only to gasp sharply as you shoved your cock back into her—already hard again—her slick walls clamping around you instantly. "Look at yourself Loona…" you growled, gripping her hips with your right hand, your other pressing against her belly—feeling the weight of your cum inside her. "Such a dumb, round, whore!! Filled to the brim by this 'Dumb Human'!!" you snarled, your hips snapping up into her violently—her body rocking with each thrust.

Loona’s breath hitched—her arms moving behind her head instinctively—her claws digging into her own silver hair as she bit her lip. "O-oh my… fuck! He’s really gonna knock me up!" she thought deliriously, her tail wagging furiously despite herself. Her mind screamed at her to resist, to push you away, but her body betrayed her, her hips grinding down onto you shamelessly, her cunt fluttering around your cock like a vice. "D-don’t talk like that!" she whimpered, her voice cracking, her ears pinned back, her belly jiggling obscenely with each thrust. "I-I’m not… *Hnngh!* a whore!" she lied, her words dissolving into a choked moan as you slammed into her cervix.

You smirked, watching her struggle—her face twisted in pleasure, her fur matted with sweat, her huge breasts bouncing wildly. "I think your lying," you growled, suddenly grabbing her arms and pulling them back down—forcing her chest forward as you thrusted deeper, feeling your third orgasm peaking already. "Now, be a good gkrl and take it ALL!!" you snarled, your fingers digging into her forearms. Loona’s eyes rolled back, her mouth dropping open, her entire body trembling as she felt your cock twitch inside her—her instincts screaming at her to *BREED*.

"My body’s breaking…" Loona whimpered, barely coherent—her words slurred—her eyes half-lidded as she stared up at the ceiling. "T-too…much…" she gasped, her tongue lolling out, her tail stiffening as she came yet again—her juices splattering onto the floor beneath you both. Her swollen belly swelled further as you erupted inside her, another tidal wave of cum flooding her womb, her bellybutton popping out from the sheer pressure.

With each orgasm, you switched positions—forcing Loona onto her back, onto her side, onto her knees—each time driving deeper, harder, faster, her belly ever growing larger and larger, until she physically couldn’t move anymore, her body too bloated, too swollen, her body pinned pinned on her back, her belly obscenely distended—her flopped to either side of her mountainous stomach, her thighs spread wide, her legs twitching weakly, and her tail limp on the floor.

You’ve long since pulled out of Loona, having shoved one of her buttplugs inside her cunt to keep your cum from spilling out, but she’s so full, it’s dripping from her swollen cunt anyway, pooling beneath her. Her breathing is shallow, her tongue lolling out, her slit pupils completely dilated, she looks like she’s barely conscious, her chest rising and falling weakly, her ears twitching with each breath.

Additionally… something else changed with Loona, her personality. She’s normally so angry, aggressive, but now, you’ve fucked her into submission, she’s docile, obedient, her tail wagging weakly whenever you glance at her. She’s *happy*, her instincts fully satiated—she whines softly when you crouch beside her, pressing a hand against her swollen stomach, feeling how drum-tight it is. She blinks slowly, her tongue sticking out further, her tail wagging faster when you rub circles into her belly.

"Such a good girl, aren’t you?" You murmur, scratching behind her ear—she whimpers, leaning into your touch, her ears twitching happily. "Y-yeah…" she slurs, her voice hoarse from screaming earlier, her claws flexing weakly against the carpet. "I-I love you, Matthew~" she murmurs, her words thick with exhaustion and contentment—she’s never used your actual name before, always just calling you ‘Fatty’ or ‘Dipshit.’

You chuckle, dragging your fingers down her belly—she shivers, her tail thumping weakly. "Oh really? Well, what kind of love are we talking about?" You tease, pressing into the taut flesh, watching her squirm. "Mmm… puppy love~" she giggles sleepily, her muzzle curling into an uncharacteristically sweet smile—she looks completely blissed out, her eyes half-lidded as she watches you through her lashes.

Her belly gurgles audibly, and she whines, pressing her paws against the swollen curve. "Gonna… gonna burst," she mumbles, shifting slightly—her legs wobbling when she tries to lift them. "Should’ve thought about that before begging for pups," you smirk, leaning down to nip at her ear, she gasps, her hips jerking weakly. "Sh-shut *up*…" she whimpers, but there’s no bite to it, just a flustered, dazed embarrassment.

"Loona…" You trail a finger down her sternum, watching her fur prickle. "Did you mean it?" Her ears twitch, her tail thumping once—slow, hesitant. She avoids your gaze, chewing her lip before sighing. "Mmf… yeah. Yeah, I meant it," she grumbles, then adds quieter, "Dunno why, though. You’re still a *fucking* idiot." You laugh, rubbing her belly again—she groans, her cunt clenching around the plug, a fresh trickle of cum seeping out.

The apartment smells like sweat and sex, the TV still playing some forgotten infomercial in the background. Loona’s breathing evens out, her paws kneading her own stomach absently. "Fuckin’… ruined me," she mutters, but there’s awe in it. Her hips shift, testing the weight—her belly sloshes audibly, and she whines. "How the *hell* am I supposed to clean this up?" You shrug, leaning in to kiss her furry cheek. "I don’t know… but one thing is for sure—you’re my girlfriend now."

Her ears perk up, her tail thumping weakly against the floor. "Tch. Like I’d let *you* claim me," she grumbles, but her voice lacks its usual venom. She stretches, wincing as her belly shifts, then sighs dramatically. "…Fine. But *only* because I don’t want to be alone during this pregnancy." You raise an eyebrow. "So… you *are* pregnant?" She rolls her eyes. "With how much cum you pumped into me? *Obviously.*"

A soft whimper escapes her as she tries to sit up, failing miserably under the weight of her own bloated stomach. "Ugh… *help*, you idiot." You smirk, sliding your arms under her shoulders and lifting—she whines as gravity tugs at her belly, her paws instinctively clutching it. "Fuckin’ hell… gonna pop like a balloon," she mutters, her tail curling around your waist for balance. "You’re carrying me to bed. *Now.*"

The walk to the bedroom is slow, her legs shaky—every step makes her belly slosh, her breath hitching. "Nnngh—*slow down*, dipshit!" she growls, but it’s half-hearted, her claws digging into your shoulders more for stability than malice. You deposit her onto the mattress, her body sinking into the comforter with a wet *squelch* from the plug still lodged inside her. "Gross," she murmurs, but makes no move to remove it, instead sprawling out with a contented sigh.

"Loona… it appears you’ll need to learn some manners," you muse, watching her tail flick lazily. She scoffs, rolling onto her side—or trying to, her belly preventing her from fully turning. "Fuck off. I just got *ruined* by your stupid dick—I get a pass for today." Her ears twitch when you straddled her thighs, laying your body weight onto her bloated stomach. She groans, her paws pressing against your chest. "The *hell* are you—nnf—doing?!"

You grin, reaching out to hug her massive midsection. "Get ready Loona… this life of yours is about to get a lot more *submissive*." She stiffens, her fur bristling—then wraps her arms around her breasts to hide them when they jiggle as you rock against her. "Y-you wouldn’t *dare*—" she starts, but her breath catches when you squeeze her belly, making the trapped cum shift inside her. "Oh… oh *fuck*…" she whines, her claws flexing against her own arms. "What… what have I walked into…?"

For the next eight months, you grueling trained her—forcing her through relentless sessions of breeding, every climax was another step toward molding her into the perfect puppy-brained mate. By the end of it, she was indefinitely pregnant, indefinitely submissive, and completely addicted to your touch—her belly was *massive* now, barely able to walk without assistance, her instincts fully rewired to crave your dominance.

"Ooohhh Looooonnnnaaaa~" you called out for her from across the apartment—instantly, she came crawling to you on all fours, her engorged belly swaying beneath her. She didn’t speak, instead she barked, though it merely sounded like her just saying either "Ruff!" or "Wuff!"—she was fully conditioned to act like a bitch in heat, regardless if she was once a walking, talking, sentient Hellhound.

She stopped in front of you, pressing her muzzle against your thigh—her tail wagging furiously behind her, her belly pressing against the couch. "Whose a good girl?" You teased, scratching behind her ear—she whimpered, her tongue lolling out as she pressed further into your touch. "M-me!" she slurred, her pupils dilated, completely lost in her instincts.

You chuckled, motioning for her to do a trick—she rolled onto her back immediately, her swollen stomach rising like a fleshy hill above her. "Ruff! Ruff!" she panted, her paws kneading the air uselessly. The TV remote lay forgotten on the floor—she'd been fetching things for you all afternoon, her obedience absolute.

"You think you deserve a treat, puppy?" you teased, tapping your thigh. Loona whined, scrambling upright with surprising agility for her bloated state. Her tail thumped wildly against the carpet. "Y-yes! Wuff!" she stammered, her voice dripping with desperate eagerness—her old snark buried under layers of conditioning.

Rolling your eyes, you reached into the snack bowl on the coffee table and snatched up a meat stick, holding it in front of her muzzle. "Open," you commanded. Loona hesitated—a brief flicker of her old defiance—before her instincts surged and she parted her jaws obediently. You chuckled as she nibbled it delicately from your fingers, her tongue swiping your palm clean afterward.

"Now sit," you ordered, pointing at the floor in front of your feet. Loona's ears twitched as she lowered herself with a grunt, her belly making it difficult to balance. She tucked her legs under her bulk, tail wagging cautiously while kneading the air with her hands, her tongue still hanging out expectantly.

"You're getting better at this," you mused, rubbing the top of her head—she leaned into the touch instantly, emitting a low, happy growl. "Who knows… if you weren’t such a mean bitch before, maybe you wouldn’t have to live as my pet now." Loona’s ears drooped slightly at the remark, but she didn’t protest—just whimpered softly and nuzzled your thigh.

A sudden, loud gurgle erupted from her stomach, making her whimper and clutch at her swollen belly. "Nngh… hurts," she slurred, pressing her forehead against your knee. You sighed, sliding off the couch to kneel beside her, massaging her taut stomach in slow circles—she melted under your touch, her breathing steadying. "You’re getting close to your due date," you muttered. "Soon, you’ll pop out those pups and beg for me to fill you right back up again."

Loona whimpered, her claws flexing weakly against the carpet. "*Ruff*… hate you," she mumbled, though her tail wagged erratically as you dug your fingers deeper into her stretched abdomen. "Keep lying," you teased, leaning down to nip at her ear. "This life will only get worse for you." Her breath hitched—her body stiffening—before she shook her head violently. "*Wuff*! N-no! Forgive Loona!" she blurted, her voice cracking with desperation.

You smirked, watching her instincts override her pride. "Good girl," you murmured, scratching under her chin—she shuddered, her tongue lolling further. The apartment fell silent save for her ragged breathing and the distant hum of the TV. Then—a wet splash. Loona gasped, her ears pinning back as a warm trickle ran down her inner thigh. "O-oh *fuck*…" she whined, pressing her paws against her belly. "I-it’s—*hnngh*—happening!"

Her claws dug into her belly as a violent contraction wracked her body. "Hmm… and here I thought you’d last another week," you mused, attaching a leash to her brand new collar—thick, padded, with spikes lining the outside. Loona whimpered, her hips rocking instinctively as another gush of fluids soaked the carpet beneath her. "P-please…" she panted, her voice breaking. "*Help* me—*hnngh*—you bastard!"

You yanked the leash, forcing her onto her hands and knees. "Come, let’s head to the hospital—you wouldn’t want to give birth on the floor like a stray mutt, would you?" Loona groaned, her swollen belly swaying beneath her as she crawled awkwardly toward the door, her tail tucked between her legs. "I-I hate you," she snarled weakly—another contraction cut her off, her body seizing as she collapsed against the wall. "FUCK! *It hurts!*"

"Loona…" you sighed, crouching beside her trembling form and grabbing her muzzle, forcing her to meet your gaze. "If you say another hurtful thing, I’ll leave you here to pop out these pups alone. Understood?" Her ears flattened instantly, her pupils shrinking to fearful pinpricks. "*Wuff*… s-sorry," she whimpered, pressing her forehead against your thigh in submission.

Another contraction wracked her body—she howled, claws scraping against the hardwood floor as her belly visibly tightened. "F-fuck! *MOVE!*" she snarled, shoving herself forward with surprising strength, her belly sloshing violently with each frantic crawl toward the door. You followed, leash taut, watching with amusement as her desperation overrode her dignity.

"Good girl," you murmured when she finally reached the elevator, collapsing against the wall with labored breaths. Her tail thumped weakly when you pressed the button—then immediately stilled as another wave of pain hit. "*Ghhh—fucking hell!*" she gasped, legs splaying wider as a fresh gush of fluid pooled beneath her. The elevator doors slid open to reveal a startled elderly couple. "Uh… dog?" the man stammered, eyeing Loona’s naked trembling form.

You yanked the leash sharply, dragging her inside. "She’s in labor. Move." The couple scrambled out just as Loona howled again, her claws gouging the elevator floor. "You—*hnngh*—could’ve been *nicer*!" she snarled between panting. "Still got attitude, huh?" you smirked, watching her belly ripple visibly. "*Wuff*! N-no! Loona sorry!" she yelped, cowering when you twisted the leash tighter around your fist.

The doors opened to the parking garage—Loona whimpered at the cool air hitting her soaked fur. "C-can’t crawl… too far," she gasped, her legs shaking violently as another contraction seized her. You sighed, tugging on her collar. "Too bad. Start crawling, bitch." Her ears flattened, her dilated pupils flickering between defiance and submission before she gritted her teeth and dragged herself forward. "*Fuck* you…" she muttered—then whimpered when you tugged on her ear hard. "I said *crawl*."

Halfway to the car, Loona collapsed onto her side with a guttural moan, her belly contracting visibly. "N-no… pups coming *now*!" she wailed, her claws scrabbling uselessly against the concrete. You grabbed her arms and began to drag her toward the car—she howled, her body arching as her belly bulged obscenely. "*RRRGH—STOP!* I can *feel* them!" she screamed, her tail thrashing wildly.

"Too late," you growled, tossing open the car door as Loona's body locked up—her legs splayed wide, her belly rippling in waves. "Get in. Now Loona." She whimpered, shaking her head violently—then shrieked as something inside her *shifted*. "*FUCK!*" she sobbed, her claws digging into your arms as she tried to heave herself into the backseat, her belly wedged against the doorframe. "Move it!" you snarled, shoving her the rest of the way in—her towering 8'4" ft tall form squished awkwardly against the upholstery as another contraction hit.

Loona curled onto her side, panting raggedly, her tail thrashing against the seat. "*Hnngh—fuckfuckfuck—*" she gasped, pressing a paw between her trembling thighs. "T-they're *coming*!" she wailed, her voice cracking with panic. You slammed the door shut and climbed into the driver’s seat, peeling out of the parking garage as she howled behind you—her claws tearing into the leather seats. "Drive *faster*, you idiot!" she snarled, then immediately whimpered, "*Wuff!* S-sorry—just *please*!"

The car ride to the hospital was… messy. Loona alternated between snarling curses and desperate whimpers, her body writhing as contractions wracked her frame. At a red light, you turned to see her crying openly, her head shaking wildly. "I-I can't—*hnngh*—hold them in anymore!" she sobbed, her thighs glistening with fluids. "Please! *Please* help me!"

Once you arrived at the hospital, you had her crawl her way inside—despite her obvious distress—while barking at anyone who dared stare too long. Nurses scrambled to assist as Loona collapsed onto a gurney, her claws sinking into the sheets. "Where's—*RRGH*—the damn doctor?!" she roared, her belly visibly shifting as the pups descended further. A harried-looking OBGYN burst in, barely avoiding Loona's flailing tail. "Alright, let's—"

"NO TIME!" Loona shrieked, her legs spreading instinctively as her body arched off the bed. "*THEY'RE COMING!*" Her agonized scream echoed through the ward as the first pup crowned—her muscles straining obscenely around the emerging form. You smirked, offering her a stress ball—which she crushed instantly. "Breathe, Loona," you murmured mockingly. "FUCK YOU!" she snarled—then clamped her hand over her muzzle mid-sentence, remembering her conditioning. "*Wuff*...sorry..."

The doctor barely had time to glove up before Loona's belly contracted violently—her entire body locking up as she bore down with a guttural howl. "*RRRRGH—TAKE THEM!*" she sobbed, her claws shredding the hospital sheets. The first pup slid out in a rush of fluids—tiny, whining, and already squirming—followed immediately by another. "*AGH—TOO MANY!*" Loona gasped, her tail thrashing wildly as she pushed again, her belly visibly deflating with each birth.

"Seven so far," the nurse murmured, wrapping the squirming pups in towels while Loona panted between contractions, her tongue lolling. "*Fuck...how many...did you put in me?!*" she slurred, her dilated pupils struggling to focus. You smirked, counting the squirming bundles. "Enough to make sure you'll never question who owns you again." She whimpered, her ears flattening—then cried out as another pup forced its way free. "*Hnngh—FUCKING STOP!*" she wailed, her paws scrabbling at her belly. "No more...*please*!"

The doctor pressed a towel between Loona’s trembling thighs. "One more," she said briskly—Loona’s tail stiffened. "*NO!*" she shrieked, her claws sinking into your forearm. "I can’t—*hnngh*—*take it!*" Her body convulsed, her back arching off the bed as the final pup slid out with a wet *pop*. Loona collapsed, her chest heaving, her fur matted with sweat. "Everything’s going… going dark…" she mumbled, her eyelids fluttering before she passed out cold.

When she came to, the nurses had already cleaned her up—her belly deflated but still softly rounded, her thighs sticky with drying fluids. The pups—eight in total—were nestled in a heated incubator nearby, mewling faintly. "Fuckin’… *eight*?" Loona croaked, her voice hoarse. She turned her head weakly toward you, her ears twitching. "You… you *monster*." You sighed, shaking your head. "You’re getting punished for that later." Her tail stilled—she swallowed hard, her slit pupils dilating further.

She tried to sit up, then groaned as soreness shot through her body. "*Oof*… everything hurts," she muttered, flopping back onto the pillows. A nurse approached, adjusting her IV. "You pushed out eight healthy pups in under twenty minutes," she said flatly. "*Most* Hellhounds take at least three hours." Loona’s ears flattened. "*Tch.* Course I’d break records for this bullshit," she grumbled—then yelped when you pinched her thigh. "*Wuff!* S-sorry!"

Her gaze drifted to the incubator again, watching the tiny forms squirm. "They’re… loud," she mumbled, her tail twitching uncertainly. One pup let out a particularly sharp cry—instantly, Loona’s ears perked up, her nostrils flaring. Without warning, she plugged her ears with her paws and *growled*, low and rumbling. You glanced down at Loona, before moving her hands away—her pupils dilated as the noise of the pups crying filled her ears again—she whined, pressing her forehead against your thigh. "*Too much*," she mumbled.

"Loona, do you even want them?" you asked bluntly, watching her reaction carefully. She stiffened, her claws flexing against the sheets before she exhaled sharply through her nose. "No…" she muttered, avoiding eye contact. "I don’t want them growing up in a home with *you*." You frowned, gripping her chin and forcing her to look at you—her pupils shrank under your gaze. "*Wuff*! I-I mean—" she stammered, her tail curling around her leg nervously.

The nurse cleared her throat awkwardly, glancing between you both. "We can arrange adoption if—" "How soon?!" Loona interrupted, her voice cracking with desperation. The nurse blinked, taken aback by her urgency. "Within 24 hours, once the paperwork is—" "Good," Loona growled, cutting her off again, her claws digging into the mattress. "Take them." You chuckled darkly, running a hand through her sweat-matted fur. "Well… looks like you’re already learning to be a good mom." She flinched, her ears flattening against her skull. "*Fuck* you," she hissed—then immediately whimpered when you twisted her ear sharply. "*Wuff*! I-I’m sorry!"

Loona turned her face away, her tail curling tightly around her thigh as she stared blankly at the incubator. The pups’ cries filled the room—tiny, high-pitched whines that made her claws flex involuntarily. "If there was only a way I could stop myself from—" she mumbled, then froze mid-sentence when she realized what she was saying. Her ears twitched nervously, glancing up at you through her lashes. "I-I want my tubes tied," she blurted suddenly, her voice hoarse. "Right *now*."

The nurse hesitated, glancing at you for confirmation—Loona snarled, her fur bristling. "*Don’t* look at him!" she snapped, then flinched when you squeezed her thigh warningly. "*Wuff*! I-I mean… please," she added through gritted teeth, her tail thumping weakly against the bed. The nurse nodded slowly. "We can schedule it for tomorrow, after recovery." Loona exhaled sharply, her shoulders sagging in relief. "Good," she muttered, her claws kneading the sheets absently. "No more… *this*."

You smirked, tracing a finger along the curve of her deflated belly. "You realize that without the fear of pregnancy, I can *really* ruin you now, right?" Loona stiffened, her ears pinning back—then groaned as another aftershock of soreness wracked her body. "*Tch.* Like you haven’t already," she grumbled, but her voice lacked its usual bite. Her tail flicked nervously when you leaned in close, your breath hot against her ear. "Oh Loona… you have *no* idea what’s coming." She shuddered, her slit pupils dilating further. "*Fuck*," she whispered.

Six weeks passed since Loona gave birth—her body mostly recovered, though her belly remained slightly softened, and she had her tubes tied as she wished. One evening, she crawled into the bedroom on all fours, her tail wagging hesitantly as she nuzzled your thigh. "*Wuff*… Matthew?" she murmured, her voice uncharacteristically small. You glanced up from your book, raising an eyebrow. "Hmm?" She hesitated, her claws flexing against the carpet. "I… I’m sorry for being a bitch," she mumbled, her ears flattening. "Please don’t make my life a living hell anymore."

You sighed, setting the book aside and patting the bed beside you. "Come here." Loona scrambled up eagerly, curling against your side—her warmth radiating through your clothes. "How badly do you want to no longer be a pet?" you asked, scratching behind her ear. She shuddered, pressing closer. "*Ruff*… so bad," she whispered, her voice cracking. "Being forced to bark, crawl… it’s *humiliating*." You chuckled darkly. "Is it now? What about all the times you called me 'Fatty' or 'Dipshit'? You think that *wasn’t* humiliating?" She winced, burying her muzzle in your shoulder. "*Wuff*… I was stupid."

Another silence stretched between you—Loona’s tail twitched anxiously. "What if…" she started, then swallowed hard. "What if I promise to behave?" You snorted, tilting her chin up. "*You*? Behave?" Her ears drooped. "Yeah, yeah, laugh it up," she muttered. "But I mean it this time." You hummed, dragging a fingernail down her sternum—she whimpered, her fur bristling. "Fine," you conceded. "But I get to set your role in this relationship." She nodded eagerly, her tail wagging slightly. "*Ruff*… deal."

Her ears perked when you pulled her on top of your lap—her legs instinctively straddling your thighs. "Firstly, you can stop barking, crawling, and begging," you murmured, tracing circles on her hip. Loona exhaled shakily, her claws flexing against your shoulders. "Fuck, *finally*," she groaned, her voice thick with relief. You smirked, squeezing her waist. "Secondly…" Her breath hitched as your grip tightened. "Your role will be to be mine. You will practically be my wife—and you will love every second of it."

She stiffened, her tail flicking uncertainly. "You… your wife?" Loona repeated, her voice cracking slightly. You chuckled, pinching her chin. "Yes. My wife. Who cooks, cleans, and spreads her legs whenever I want." She scowled, her ears flattening—then sighed, rubbing her face. "*Fine*. But—" Her protest died when you pressed your thumb against her lips. "No 'buts.' Unless you want to go back to being a pet?" Loona shuddered, shaking her head violently. "*No*," she mumbled, her tail tucking between her legs. "I’ll… I’ll behave."

A slow smirk curled your lips as you dragged her into a rough kiss—Loona whimpered but didn’t pull away, her claws digging into your shoulders. When you broke apart, she was panting, her pupils blown wide. "Loona… do you hate me? Or do you… *love* me?" you murmured, tracing the curve of her fang. She hesitated, her ears twitching—then exhaled sharply. "*Tch.* Obviously… I love you," she muttered, her cheeks darkening beneath her fur. "Happy now?"

You flicked her nose, making her growl halfheartedly. "Lose the attitude. Say it properly." She bared her teeth, tail lashing—then deflated with a groan. "Fine. *Matthew*, I love you," she grumbled, rolling her eyes. "Even though you’re a fucking *monster*." You chuckled, squeezing her thighs. "Oh I’m the monster, am I?" Her ears pinned back instantly. "Shit! Sorry… I’m still getting used to me *not* being a bitch," she mumbled, rubbing her face.

Loona hesitated, then slowly wrapped her arms around your neck—awkwardly, like she wasn’t sure how hugs worked. "Just… be patient with me, okay?" she muttered into your shoulder. You smirked, patting her rump. "Only if you stop swearing. Indefinably." She stiffened, her claws pricking your skin. "*The fuck*—?" Another smack silenced her. "*Fine*," she huffed, her tail thumping against the mattress in frustration. "No cursing. Got it."

Her stomach growled loudly, breaking the tension—Loona flushed, pressing a paw to her belly. "Hungry?" you teased. She scowled but nodded. "Yeah. Haven’t eaten since… well, *before*." You chuckled, unbuckling your pants. Her ears shot up. "*Wait*—no! Not *that*!" You shrugged. "Protein’s protein." She gagged, shoving your hands away. "*Disgusting*. I meant *actual* food, you freak!"

Rolling your eyes, you freed yourself anyway—Loona hissed but didn’t pull back. "You did agree to spread your legs whenever I wanted," you reminded her. She groaned, tail lashing. "*Fine*. But I need actual dinner after this." You smirked, dragging her muzzle down. "Deal." She grumbled something unintelligible before reluctantly parting her lips—her grip on your thighs tightening as she swallowed you down with practiced ease.

As she worked, she brought her breasts up on either side of your cock—the heat and pressure making you groan. Loona glanced up through her lashes, her tail wagging slightly despite herself. "*Mmph*… happy?" she mumbled around your length. You chuckled, tugging her ears lightly. "Ecstatic." She rolled her eyes but didn’t stop, her motions growing smoother as she lost herself in the rhythm. The bed creaked faintly beneath her shifting weight.

When you finally came down her throat, she swallowed instinctively—then gagged, pulling back with a scowl. "*Ugh*—why is there so *much*?" she grumbled, wiping her muzzle with the back of her paw. You smirked, tucking yourself away. "Complaints already? And here I thought you were *behaving*." Loona huffed, crossing her arms over her chest—then winced as her stomach growled again. "*Food*, Matthew. *Now*," she demanded, her ears flattening.
