“Well, this is... cheery.” Mora surmised. She stared, hands on hips, at the grim sight that the girls had beheld as soon as they’d swung open the door at the top of the stairway. 
Before them a long, wide hallway stretched straight ahead, long enough that even the tall doorway at the far end seemed about half a mile away. To call the abundant torch sconces lining the rafters a boon would have been but a half truth, for while they certainly illuminated the path clearly, they also made obvious the rows of what seemed to be prison cells, or perhaps cages built into the stone walls, lining the corridor right up until the other end. The cells nearest to them were empty of anything living, though that emptiness carried with it the ominous implication that whatever had been in there before seemed to leave of its’ prey nothing but bones. 
“Ooooh, creepy.” Geecku surmised. 
“That’s... one word for it.” Mora shrugged. “But that’s a dungeon for you, can’t afford to underestimate these places. Otherwise, best case scenario you end up head over heels in lust for a big gross troll, and worst case scenario you end up like Yorich, here.” Mora said, kicking an errant human skull left laying on the filthy floor which practically caved in from her boot’s lovetap.  
“Enough philosophising, turbo tits, time is treasure.” Rach groaned, already ignoring the grim bric-a-brac of the hallway as she began confidently striding down the hall. 
Before Mora could retort, her words were interrupted by a shrill, scraping bark.
“AAHHSHITFUCKNOOOOOO!” Rachael instinctively yelled, impressively turning four  words into a one syllable squeal as she cowered away from the noise. 
The barking continued, while gnashing jaws collided desperately against the metal bars of the cell on Rachael’s left. A huge canine, feral in anatomy and comparable in colourings and musculature to a common Rottweiler yet no less than five feet in height, was furiously growling and salivating just beyond the bars. Between its’ physical size, its’ three pairs of legs, gills running along its’ massive muzzle, and furiously splattering saliva a deep, swampy green, it was clear that this was a product of some ghastly transmutation.
Slowly but surely, Rachael came to recognise that however intimidating the beast was, it was for the time being, trapped. She came to her senses just in time to hear Mora’s raucous, snorting round of laughter. 
“Awww, whassa matter? Is the kitty afraid the big bad doggie’s gonna eat you up?” Mora teased, patting her comrade firmly between the shoulders. Geecku prowled up behind, cheekily chuckling. 
“Like you would’ve seen that coming.” Rachael huffed. “Lets’ just go already, before that mutt chews through the bars and shows you how unfunny that was.” She hissed, already storming off with a renewed confidence, or perhaps simply a brave face. 
“It was kinda funny.” Geecku whispered. 
Mora smirked, ruffling the girl’s hair before they too walked on, the dog’s ongoing barks now music to their ears, in a dark, cathartic sort of way. 
With their pace slowly gaining momentum and confidence, the trio worked their way along the hall. Almost all the cells they passed were empty, save for one which housed a particularly intimidating canine of the same variety as before, the likes of whom could still be heard yapping away far behind them. In contrast to its’ companion, this beast was simply pacing along the bars inside its’ cell incessantly, snarling out at the group.  Geecku, inexhaustibly enthusiastic and athletic, had taken to clambering along the beaten up walls and bars of the cells that were empty, or occupied only with the grim remains of slain canines and adventurers alike. She seemed the least phased of the trio, giggling and mimicking the movements of the growling, scar-faced hound as she passed by.
Rachael suddenly felt a twinkle of light reflected into her eye. She winced momentarily at the unpleasant flash, before realising from whence it came. A row of glistening, dangling metal spikes, like a row of teeth, lined the top of the doorway ahead subtly. She recognised it immediately. 
“That door’s got a portcullis.” 
“Huh?” Mora asked, not bothering to look Rachael’s way as they continued walking. 
“A portcullis, dummy. A big heavy metal gate that you can’t brute force your way through no matter how much you punch it. I know, impossible, right?”
“Don’t get smart with me. I know what a portcullis is. But if it’s there to keep us out, why’d the geniuses behind this place leave it open?” 
“Because it’s not there to keep us out, heifer. It’s there to keep those poochies in, with us.”
Mora gritted her teeth, but strengthened her resolve and sighed the slur off. Rach was probably just still sore over her earlier scare. 
“Would explain all the sunshine and lollipops all over the floor. There must be a switch or button somewhere that releases the hounds.”
“Yeah, well, I’d rather not find it. And all the more reason to watch your step, else your fat feet might just step on it.” 
“Oh, can it, kitty. Those poochies wouldn’t want you as a chew toy anyway. Not enough meat on your bones, girl.” 
“Better off meaty where it counts, rather than being a walking talking beef burger.” 
Mora turned in place, almost prompting Rachael to collide into a wall of chiselled tan bovine. 
“Alright, that’s it. You may not like being stuck with me but at least I’m trying to keep my eyes on the prize here. So either shut your hole and follow me or go crawling back to help that blue ballsucker wolf down her dinner of troll jizz. You wanna make it in the raiding business? Better grow a thicker skin, princess.” 
“Or a thick skull in your case, cow. I’ve put up with your dumb ass playing leader of the pack until now but if you can’t get anything but greed through your head then I’m the only one who can lead this group safely.” 
“You couldn’t lead a horse to water, bitch.” 
“You couldn’t lead a dumb mage wannabe away from a dumb beast’s dick.” 
“Fuck you!”
“FUCK YOU!” 

“Hey girls?” Geecku chirped from ahead. 
“WHAT?!” They snapped her way. Instantly, their expressions fell like anvils from a rooftop as they saw Geecku’s hand pulling the lever.
“Whass’is do?” 

The effects were instantaneous. With a pained rumble, the bars on all the cells lining the corridor began to lift, the rusted metal squeaking and howling in reluctant motions as the mechanisms linked to the lever Geecku was still innocently grasping began freeing the canine prisoners. Already, the two remaining hounds the girls had seen so far were snapping at the gradually widening gap between the blood drenched ground and the raising bars to their cages, desperate for escape and hungry for flesh. 
Mora then hollered the wisest order she’d given to the group all day. 
“HAUL ASS!”
Mora and Rachael sprinted down the corridor, all arguments promptly shelved in the backs of their minds in favour of survival. At the very least, they had a head start on their feral pursuers, the likes of whom were now shuffling and scurrying out of their cells and bounding into the corridor. What was more, unlike a certain mage they knew, the trio was not weighed down by encumbering, large or heavy clothing, which improved their speed considerably, even if their generous breasts certainly weighed them down to some extent, jiggling in rhythm with each step. 
That head start proved to be a minimal advantage, as it soon became clear how fast the dogs were barrelling down the hallway, closing the distance. An astonishing feat, considering not all the cells were even fully open by now. Mora and Rachael knew better than to look back; the snarls and growls and yaps behind them were getting louder, and that was more than enough motivation needed to run for their lives. 
Geecku sat ahead of them, by the lever she’d so foolishly pulled, next to the tall exit where sure enough, the portcullis had already started lowering at an alarmingly fast gait. The hounds were hot on their heels, but the end of the hallway was not far off. Having pulled ahead of Mora, Rachael reached out to Geecku, intending to grab her impulsive ally and drag her through the gateway. 
At least, that was the plan until a third hound tackled Rachael in the ribs. Having been freed from its’ cell right by the closing gateway, it had immediately pounced Rachael, sending the kitten sliding along the dusty, dirty ground, the impact kicking up dust while raining saliva down from it’s repulsive wide maw. 
The beast was snarling and snapping in the pinned rogue’s face, while Rachael did all she could in her winded state to force it’s jaws away from her guttural. It was half the size of its’ larger brethren, whose heavy paws were still causing thunderous vibrations in the ground as a constant reminder of their encroaching presence. But size didn’t matter when you had fangs that could crack an adventurer’s head like a nut. 
Rachael screamed and struggled, the dog’s teeth inching closer and closer to her bare, tender fur coat as her strength began to fail her...
Before a mighty swing sent the pooch throttling into a wall with a squelching thud, and a weak whimper as it breathed its’ last. 
Mora didn’t wait for Rachael to come to her senses and catch back up with reality. She simply grasped the collapsed feline by the forearm in one of her hardy gauntlets and lifted the girl back onto her feet like she was as light as a feather. 
For a moment, the warrior and rogue shared a glance which said everything that needed saying. Rachael would never forget what had happened, and Mora was bound to make sure she didn’t. 
Provided they survived the assault thundering down at them from that pair of snarling, mutated monsters. They were getting far too close now. The ground bellowed with tremors under the beasts’ steps, their foul feral aroma thickening in the air. 
With Rachael still in her grasp, Mora made for the gateway, just in time for the portcullis to lower past their eye level. 
“NO!” Mora spat, her directionless defiance of the group’s peril almost drowned out under the vicious barking right behind them. She tossed Rachael forwards, sending the girl tumbling under the spiked metal barrier, and took a leap of faith. 

With her eyes squeezed shut and body tensed up flat on her face like a toppled statue, Mora was unsure whether she’d made it, or the pain of being skewered under the portcullis simply had yet to kick in. Yet the seconds ticked by, and she felt nothing. She opened her eyes, and saw no blood. The ringing in her ears calmed, and she heard nothing. Or, she heard something, but it was so contrary to the previous sounds of deathly barking and rusted door mechanisms  that she almost didn’t register it at first. 
Was that... laughing? 
Mora flipped herself over, baffled by the noise. First she saw Rachael, who was bruised and dirty, but alive and staring intently back behind the gateway they’d somehow snuck under. Then she saw Geecku. Alive, and dirty, but in a very different way than Rachael. And on the other side of the gateway. 
With the hounds slathering their tongues over her face and chest. 
Mora almost shrieked in the horror of seeing her comrade eaten before her eyes, before she realised their real intention. 
“Shut up.” Rachael mumbled.
“Shut up.” Mora concurred.
“Hahahahaha! Good puppies! Awwww, whossa good boy? Whossanother good boy? You are! And you are!” Geecku cackled and snorted. She was laying on her back, relaxed and calm, even as long purple tongues painted her colourful body with canine saliva, glistening with a purple tint. 
“Ew...” Rachael muttered, turning her gaze away from Geecku’s predicament with the crinkled expression of someone wrought with disgust and guilt in equal measures. 
“Um... Geecku?” Mora asked, raising her voice carefully as she spoke through the portcullis bars, seeking to get the girl’s attention without enraging the hounds again. 
“Oh! Boobie lady and cute kitty made it! Thank Maker, you two almost got smooshed or chewed up like a doggie treat!” Geecku cheerfully sighed, rolling about onto her front as the canines sniffed and slurped along her hair. 
“How did you... What is... Are you, like...” Mora stuttered, unsure where to begin. “What?!” She said instead. 
“Hah! It’s okie dokes boobie lady, Geecku’s just like... good with animals! When Geecku saw you two were about to get chomped, Geecku pounced in like woosh and gave these poochies the look Geecku gives all her animal friends when they need a time out. But turns out these pups aren’t mean, they’re just all sad about being pent up in those nasty cages for so long!” 
“But... you’re stuck there now. Let me see about getting you outta there...”
“Ohh,sorry boobie lady, Geecku doesn’t think that’s a good idea. Geecku can distract these boys a while, but if we open the gate up again so Geecku can run, they’ll get mad for real! Then we’d all be on the menu!” 
“So, what, we’ve gotta leave you here?” 
“It’s okay, really! Geecku’s just gonna play with these pups a bit then find another way out and catch up with you two!” 
Mora paused, then glanced at Rachael. The kitten had sat herself up against the wall, one hand over her toned abdomen where the smaller pup had rocketed into her. Her stockings were laddered and dotted with holes torn open. Hadn’t she had two knives before, too? 
The rogue was in no shape to fend off another assault. Mora gritted her teeth and practically shouted to Geecku out of resolute frustration. 
“Come find us soon, okay? We’re getting out of here together.”
“Sure! Oh, boobie lady?”
“Yeah?” 
“Geecku’s sorry she screwed up before. Is Geecku a good adventurer?”
Mora froze up for a moment, hearing only Rachael’s weak footsteps climbing the staircase behind them. 
“Yeah.” She said, turning just in time to hide her expression as she walked on. “You’re the best, Geecku.”

For some minutes, the giggling, snorting, and playful slobbering continued, there at the end of the long hallway, grimly stained with the blood and remains of so many hopeful heroes that had raided that far into the dungeon over what must have been decades. 
Contrary to the fates of those doomed souls, however, the solitary adventurer that had remained in the kennel with her newfound canine companions was finding her experience to be quite the playful one. 
After Mora and Rachael ascended the stairs out of sight towards whatever else awaited further into the dark depths of this strange realm, Geecku had allowed herself to really unwind with these poor pups who had been deprived of kindness or playtime for so long. From playing fetch, to racing them up and down the hallways, to playfighting and belly scratching, Geecku immersed herself fully in her antics with these oversized, fearsome hounds. No matter their size, looks or demeanour, they were still creatures of the animal kingdom, her own kin, and would be treated with the respect and compassion she showed all living things. 
It was not long until Geecku was able to show her compassion in an entirely deeper level, either. 
After a particularly rousing tussle around the kennels with the duo which saw her bounding about and dancing her way around the dog’s lighthearted swats and tackles, Geecku had managed to pin one of her hounds down onto his broad belly, with her comparatively small body straddled possessively atop his torso. He could easily have rolled over at any point to send her toppling off of him, but he lay submissively and calmly, tongue lolling and panting from his maw, as if in respect for the wild woman that’d tamed both him and his friend. 
“Gotcha!” She chuckled, eyes slitted mischeviously with hands splayed out firmly, beginning to caress the canine’s shallow coat of fur she’d captured under her sunny yellow thighs. Her fingers swept forwards and back, pushing and pulling her upper body and her arms’ reach gradually further until she was practically lying on the hound’s belly. Geecku’s gaze had remained locked on the pup’s visage throughout, with a wide grin plastered cheek to cheek. That was until she felt a new warm presence prodding at her rear from behind her. 
Geecku knew what it was without having to look. But she glanced anyway, tossing her long wavy blue locks over her shoulder as her neck turned to glance over her shoulder, where an engorging, deep red, lightly knotted canine member was standing to attention. 
Geecku turned back to face her hound, and immediately planted a long, deliberate rasping lick over his muzzle, received with steamy panting from the beast who bucked its’ hips upwards impatiently. 
“Naughty puppy.” Geecku growled, already shuffling herself downwards, her breasts smearing into the canine’s fur in the process. The friction soon caused her generous bust to slip out of the handmade pelt that was barely restraining her to begin with. Geecku didn’t seem to mind. Indeed, the first thing she did when curving her spine back upwards to sit upright, was to tear her top away with her strong clawed hand, tossing it to the wayside as her perky bosom jiggled into freedom. 
“Geecku don’t like clothes anyway.” She muttered. “They get in the way of what Geecku want...” Her words trailed off as she bent her back further still, neck craning and head soon upside down. After planting her hands on the canine’s thighs, and lifting her own hips with the strength, flexibility and command over one’s body gained only from a lifetime of surviving in the natural world, Geecku somersaulted backwards, her loincloth flopping upside down with the slow but perfectly honed acrobatic motion. The canine’s cock prodded her in the back as she flipped her body over it; evidently he was impressed as well as aroused. 
When her hips tumbled back down to earth, Geecku wasted no time. With one hand pressed to the dog’s thigh and another soon cradling his generous balls, the wild woman let out her long forked tongue, letting it slather from base to tip along the thick crimson cock laid out like a meal before her eyes. 
“Haaaaaahhnn~” Her breath steamed along the sensitive shaft, tongue resonating by virtue of the sound. Her predatory gaze, alight with erotic hunger, ate up the very sight of the cock that twitched excitedly against her oral muscle, while its’ actual taste washed down her throat. Unclean, somewhat, but more importantly it was an all natural, pure, animal taste. Something that the manmade world could never replicate or replace. It made her head swim, eyes roll and tail tremor. Sometimes, she adored her own addiction.
While rasping and twirling her tongue across the tip of the cock with her hands grasping and teasing pleasure out of his balls with slow squeezing motions, Geecku realised how long it had been since she’d had a good lay. 
A day? Two days? How had she managed to cope?! 
Perhaps it was the flavour of masculine musk that she inhaled with each breath, each more shuddered than the last with how capably it brought heat and moisture to her loins, perhaps it was the impressive size and girth of this member which trickled pre in abundance from its’ pointed tip like a hearty appetiser, or perhaps Geecku was just excited at the prospect of this very unique sexual encounter. 
Whatever the reason Geecku only knew that she was aching to get fucked by this monster of a hound. And judging by the whimpers he gave while melting under Geecku’s oral assault, and the way his knot was gradually inflating at the base of his girth, Geecku surmised that he was raring to go too. 
Like the signature of a professional marked at the footer of an official decree, Geecku applied a firm, slathering, mouth-stuffing kiss to the head of that canine cock, with eyes cutting through the dim kennel torchlights into the hound’s eyes, before popping right off of her meal with a singing sigh. 
“Mmmnnh, good boy... Geecku wishes she could feast on your yummy dick, but Geecku’s gotta find her friends, and besides...” She whispered, while nuzzling her cheek along the bumpy, routinely twitching sexual flesh. 
“Geecku needs to get fucked right now.” Her voice had taken a sudden stern turn, marking her intentions clearly while she trailed her body up from where she’d been sprawled between the pooch’s thighs. While deliberately dragging that member between her deep cleavage and beautifully smooth yellow belly, Geecku perched herself in much the same position she’d been in after winning their previous little tussle. 
Except this time, her loincloth had been torn to the wayside, and her soaked mound was prodding into the canine’s cock. Her fingers tickled up the flesh, lips puckered and voice cooing. 
“Such a big, juicy dick... Mmmm, you’re lucky Geecku’s flexible enough to take it aaaall in...” She giggled. One of her hands massaged its’ way up the hound’s ribs in a most atypical ‘belly rub’, while the other grasped her treat three inches down the length and kept it steady while her pussy got in prime position to take it inside her. 
Geecku pressed down into the hound’s chest with her right hand, and with her left, squeezed his member just enough to summon a whimper from the beast’s jaws. 
“Mmmmm, you’ve been soooo patient, puppy... Now, lets’ really play~” Geecku said no more before sinking her hips, inch by inch, second by second, onto the spearing pillar of canine cock beneath. She freed her left hand and planted that too on his chest, once he was deep enough inside that he couldn’t slip out. 
Before Geecku could slam her hips down, the puppy rutted his hips up, bulging Geecku’s pussy down to the thickening of his knot. On pure instinct, her body followed him back down, desperately keeping herself as full of his feral member as she could possibly be. 
“Oooooooooooohh!” She happily sang with wide eyes, flexing claws and quivering folds. Once her nerves, head and breasts came jiggling back down to earth, Geecku was possessed of a single desire, the likes of which she pursued proudly. 
“Geecku’s gonna fuck your brains out, puppy!” 
As a woman in equally acute control of her sentient mind and animal instincts, Geecku was afforded what some may have called ‘the best of both worlds’. In no context was this statement more true, Geecku herself believed, than when it came to sex. Between her tough toned body built for battle and breeding alike, and her sentient imagination capable of devising creatively carnal ideas, she thought herself to be a partner that any bedfellow of hers would have to bring their best just to keep pace with. 
Nevertheless, the purely feral fuckbuddy she was clapping her thighs and jiggling her ass atop was certainly putting up a firm fight.  Even while his forelegs were kept tucked into his body, his hips and hindlegs more than compensated. Befitting of a beast bred to sniff out, chase and devour its’ prey without mercy, not a shred of fat marred its’ sleek canine musculature. While its’ submissive position underneath Geecku was hardly ideal, that didn’t stop him from ramming upwards frantically, with such force that even his hearty ballsack would clap into Geecku’s jiggling rear on occasion, harshening the ripples that swayed along her rear at the root of each motion. Only his slowly but surely ballooning knot prevented her from going deeper, the hot hard phallic bulb whapping and smacking into Geecku’s petals every time they hilted. He remembered enough from their prior playtime to know that Geecku could take all he could dole out like a champion. And he was after all, an animal. His singleminded intellect now sought only one goal, with a burning vigour. Juices splashed, sweat pooled and saliva rained from around his panting maw. He would not rest until he’d knotted and laid seed within this fertile beast of a woman. 
Between his strength and endurance of the delight ofher womanhood’s velvet, slicking grip, and Geecku’s flexibility and sexual experience, it was nigh on inevitable, as well. Indeed if it weren’t for such boons, they would arguably not have been physically compatible at all. The juices painted across his member that glistened on each occasion that she rose her hips back up to the tip, mingled with her saliva, certainly helped ease their union too, but there was no denying how tight of a fit it was. Her sweat-sheened smooth golden navel bulged noticeably each time she kissed that knot. 
Geecku felt it each and every time, too. An electrifying filling feeling at her deepest depths. A constant reminder that she was stretching her limits, literally and figuratively. Rarely did she get to go as wild as this, and with a feral partner who made no hesitation or apology in letting lust overtake their every thought. She could taste his need in the air, in that cloud of musk roiling around the two of them, composed of their combined natural pheromones. She drank deep of it, and let it carry her away. Her sharp fingers would tweak, twist and flick her nipples. Her hands would frequently scrape and smear along the canine’s belly. Her head tossed and turned, steamy breaths wafting further pheromones into the foul dungeon air through whines and growls of pleasure. 
“Ohhh Maker.... Oh fuck... Fuck me fuck me fuck meeeee...” Her voice built, pitch cresting as her first climax rose up, and up, and up... When she glanced down, her own field of vision caged by strands of hair messied around in the carnal abandon, the accompanying sight of the dog’s bulge pushing her figure out from the inside was astonishing enough to almost shatter that threshold. Almost. 
“Oooohh FUCK!” She groaned, mouth agape as the heat boiled and spread from her core. “Fuckfuckfuckyesssss...” She continued under her breath, doing everything she could to cross that threshold while she sat against the knot. Hips gyrated, her hands kneading her breasts, pussy clamping... And yet, she sat on the brink, frustratingly. She knew what she needed... That knot. It wouldn’t have been wise; she still had to find her friends and she didn’t have time to stay plugged up down doggie dick. As good as the massive size of that globed-out cock base would feel... The climax, the creampie, the afterglow... 
“Fuck it...” Geecku muttered to herself, easing down the shaft with dwindling reluctance. 
Then a spare pair of paws pushed her abruptly down with what felt like the weight of a house, and all remaining reluctance in her mind was obliterated when the other massive hound’s massive cock slammed home into her puckered ass. 
Evidently between his own saliva and precum, the smart pup had lubed himself up for it to not have caused Geecku agonising pain upon entry. At least, as much could be surmised considering how hard she immediately came around both invading shafts. 
“NNNNGHRRRRRRRAAAAAAAAAWRRRRR!!!!” Geecku roared, more animal than woman by then. “KNOT ME! GEECKU WANNA BE YOUR BITCH!” The implication of her words was not wasted on Geecku herself. She knew, and meant, what she said, even through her quaking orgasm that squeezed and squirted across the girth and length of the devious doggies’ cocks. With her hair frazzled, cheeks burning and rosied, pupils vertically slitted thin in her feral madness and her tongue lopping out from between drooling fangs, she was a woman possessed by her own heat. 
She was willing, ready and aching to be their Bitch, and bare their young. With the first of many growling undulations into her depths, the beasts obliged.
Unlike his brother underneath, the canine on top was in the ideal position to rut Geecku’s rear. His frontal paws both supported his motions and restrained his ‘prey’, willing and eager though she was. In long, practiced, curving thrusts, he’d drive his violently engorged cock down time and time again into the quivering, panting colourful woman sandwiched in such a powerful bind. Even though she continued to ride the hound beneath with a harder, faster, wilder pace than ever, not once did his own hind fail to raise the bar by pounding her ass down with greater force than even this insatiable Amazon could manage. 
Geecku had never felt so full. Her own power could only give her so much leeway here, where she’d been forced into such a forcibly receptive position. But that immobility, that control shackling her usually unstoppably impulsive personality, was thrilling. They were forcing the pleasure upon her, and she was burning with delight at feeling everything they gave. The duo’s thrusts were hardly synchronised; they fucked at different rhythms, often hastening into furious blurs of sweat-splattering motion only to reel back down into sensually slow, almost compassionate humping. But she gladly forgave the lack of professional technique they showed in cooperation with one another; she didn’t want a sentient veteran humanoid lover, she wanted a fuck, with a beast. Or in this case, two. They clearly didn’t care, indeed couldn’t care, about the details. Even with their own ballsacks smacking together messily, dangling flesh colliding in a cocktail of juices, nothing but intent to breed continued to guide their thoughts and actions. 
And those knots, prodding and promising greater girth yet to be had, smacked ominously into her puckered star and sopping labia every time. 
“Nnnhhh, fuckfuckfuck! Do it!” Geecku sang. “Fucking knot Geecku!” She continued, or tried to as best she could while the hounds beat her to the punch. In truth, any sound her voice was capable of got winded out of her when those ‘puppies’ started forcing more and more of their massive plugging knots into her at the crux of each pummelling. 
At first they simply shunted themselves with greater pressure against her already taut holes, as if testing the waters. Then each following thrust began to push a little more, linger inside her a little longer, and force more of themselves inside. A meagre amount more each time making her pussy and ass yield to the thick, slick living flesh, but all new ground gained made Geecku quake and hiss. 
"So..." She gasped, her every breath a painstaking effort. "Thick..." 
Soon they were approaching the point of no return. Geecku knew she couldn't stop it if she wanted to. All she could do was ready herself for when it happened. She did so by whipping her tail into her own maw to give something to chew on, to relieve the pain, and moving her hands to her own breasts where she'd tweak her own nipples, to increase the pleasure. 
Indeed, she couldn't have stopped it, but Geecku didn't want to. She'd never wanted anything more.
It happened suddenly. With a final cry the dogs pushed in, parted her and passed the widest circumference of their knots into her holes. After that widest point breached the threshold, the rest followed easily. The residual force by which those fearsome animals slammed home made her bounce in their grip. 
This is bad, Geecku realised as soon as she was knotted. These bulbs of throbbing hot canine flesh were too big for a girl her size. They were really going to fuck her up. This was really bad.
But it felt so GOOD. 
"NNGGGHHHHRRRRRFFFFFF~~!" 
Geecku shrieked around her tail, chewing and pinching for dear life even while the hounds furiously gyrated their hips. With their knots inside their climaxes were moments away. She was miles from recovering from such a massive double insertion as those evil twin knots, and still dealing with the constant stimulation of them smearing against one another through her own insides, by virtue of their sheer girth. Not only was she physically trapped, but the crushing pain and mind breaking pleasure was dulling her thoughts and misting her sight. 
"Ugghh.. Guhhh... I... Nnnggh..." Geecku garbled, all her playful control relinquished under the nervous overload these hounds had fucked into her. Her orgasm burned through her body for longer than any high she'd known before, pushing her to the highest plane of ecstasy and keeping her elevated there, a captive of her own libido. Were her body not more or less completely shrouded by the hulking beast’s forms, her overstuffed state would have been incredibly apparent to any observers; their knots had distended and distorted her belly visibly. No matter how flexible Geecku prided herself on being, every girl had a limit. She was already creaking over the edge of that limit by the time they finally came, sending her barrelling over it to an abyss of lust. 
She was barely still conscious by the time she felt those knots releasing within her. Both canines threw their heads back while Geecku's continued tossing to and fro, as thick fertile cum hosed her insides down, the force of each generous jet of spunk pushing into sensitive specks of flesh deep inside, then flooding back out only to be stopped by both knots, serving their intended purpose with unintentional effectiveness. Not a drop trickled free, all of it serving to fill Geecku beyond her limits. Inevitably, as shot after copious fertile shot of semen pumped inside with nowhere to go and every reason to stay, Geecku's sweat-drenched sunny torso began to expand subtly but steadily with the sheer size of the double-strong load.  
Geecku's eyes were hazy, her teeth almost breaking the tough skin of her tail, hair caged over her face and saliva drooling down her chin. Yet she continued to tweak her nipples, continued to swivel her hips in a blur, continued to growl out the pleasure of being made the dogs' bitch. It wasn’t the first time she’d given herself up under the weight of a partner’s power, but never before had it risen to such a lofty bastion of sensation. The forceful strain on her belly as it bloated with vile animal cum, the flooding of her womb in what may well have been an impregnating onslaught, the warm wash of male essence up her ass pouring deepest and furthest of all... She couldn’t tell which was best. Literally, in fact; it all just congealed in her mind as she collapsed, limbs and tail falling limp with her pussy still contracting in climax after climax. 
For once the predator had become prey. Before she passed out with legs numb and yet further orgasms piling on amidst the last trickles of spunk fed into her womb and rectum, she thought of her friends.
Not out of regret or worry - she simply hoped they'd make fine prey too.
