Alistair licked his lips, though the deep purple fox had other things on his mind than eating. The bunker was underground - well, half of it - and best suited to withstand the inclement weather and landscape of a post-apocalyptic world, everything that they had known, once, collapsed into dust. Cities were ruined, rang hollow, though the fox, who was technically of the Vulpiri species, didn't remember much of that time. It had happened so long ago, he'd barely been a kit, yet he knew there was more out there for him in a world that had been decimated than there would have been.

Namely, he thought, the glow of his tongue sweeping across his muzzle, his mother. She was shorter than him, now that he was an adult, along with his sister, Amber, but the changing times had made it so that he could not look up to her. The world had shifted so suddenly that everyone, not only the Vulpiri, were forced to adapt, to change, meeting something that was supposed to only happen in cheesy films and flicks that didn't do well in the box office halfway.

His mother... Alistair growled, sprawled back on a half-collapsed sofa, though his clothing was clean, dark in shades with a mesh top cut across his chest as if he was following a gothic aesthetic that no longer had much of a place after the disaster had struck. His mother, Olivia, a fox rich in burgundy shades, curvy and alluring, claimed his attention. Not that he did not see other females there, of course not, but the swing of her hips, even then, could not stop him from pursuing her through the bunker, hungering for something that he perhaps did not quite yet understand.

But that was alright. He'd gotten with others, though his mother was plumper, curvier, the sort of fox that got his cock hard at night, though there was still little privacy at all to be had in the bunker. It was the way of it, unfortunately, though something like that could not be helped, watching her as she walked past him, her clothes fitted, though that was merely because she'd used to be a seamstress. Things like that didn't matter after the apocalypse.

There was still a cooker in their bunker and Alistair smirked to himself, swaying his flared hips, which were a little broader than his chest, as he squeezed up to her.

"You're looking so cute there, mommy..."

It could have been a tease if delivered to any other fox, but Olivia squirmed away from him, laughing.

"Oh, you! You're just trying to flatter me!"

But he wasn't. His lust had grown for her, cock hard in his black trousers, which were loose enough to slide down, allowing the tip of his blue rocket to tease against her thigh.

His mother's brow furrowed, but she did not register or recognise the feeling, shifting her weight.

"Are you ready for dinner, sweetie?"

Clueless, clueless. Alistair tucked his cock away, energy thrumming beneath the surface, lust hungering for her in his gaze. It was too much for him to hold back, sneaking a grope of her arse while she yelped and rounded on him with a spoon, though she professed that his father had been just the same as him, back when he had been Alistair's age, of course.

"Boys will be boys," Olivia muttered to herself, unaware that Alistair was not yet out of hearing range. "Oh my, what a fox he's turned into..."

But he was not yet done with her, perching at a rickety table for dinner with his sister to the side, though Amber scoffed her food without barely letting it touch the sides of her gob. She was larger than even her mother, thick around the waist with large, sagging breasts to match, a vixen who most certainly liked her food. She was a sharp, brick red, though they didn't see all that many bricks like that in the world anymore, something of their London accent lingering between them all, though it was Alistair who had retained much of the cockney twang. They all got on well enough with others, of course, but Amber hunkered down in the bunker most of the time, not seeing any need to go out.

"Hey!"

Olivia growled and smacked her son's paw away from her thigh as he slid his fingers up her leg towards her pussy, though she didn't realise that he was hard too, bulging out the front of his trousers, knot still tucked within his sheath despite his arousal.

"Keep your paws to yourself, cub!"

But he was no cub, several years an adult with a vixen before him that he could not help but pursue, the musk of the Vulpiri luring him in. Amber watched distrustfully, stealing from his plate (she "never got enough food", or so she complained, constantly) as her brother pawed at their mother as if she was a slab of fresh meat. What had gotten into him? But she didn't have a clean slate either, not exactly, pouting, lips pressed together as if there was something distasteful before her, though her possession had no true place there.

Amber, after all, had a secret, and seeing him paw at her mother wasn't helping that stay hidden, not in the slightest. She wondered a little whether there was any point in keeping it hidden - it was not as if the world that they lived in was anything at all like what they remembered, after all - but admitting to watching her brother fap, well... It didn't seem like the sort of thing that could be brought up, even at that dinner table.

It had been hot, something different for the vixen who so very rarely ventured outside. She had to make her own entertainment in there and there were only so many communication systems left, despite the technology that had been rapidly bodged together after the disaster. Their world was a mishmash of too much all clumsily squished in and her lust had flared up to simply see his paw sliding back and forth over that hard length, her breath catching.

In her mind, her brother belonged to her. But that had always been the possessive way of the Vulpiri. Maybe it only came forth so strongly for Amber due to their isolation.

Alistair, however, knew none of that, days passing, not much changing in bunker life, though he did not bother venturing outside when he had so much in there to occupy him. His mother shoved off his advances, but she was hardly convincing at all about it, her tail flicking, scoffing and telling him off - though she had to realise that her son was not a mere boy anymore.

"Alistair! You've got to learn to keep your paws to yourself."

Oh, he was being a boy, playing the same games that his father had, yet Olivia completely failed to recognise just how that was playing out, the dangerous path that she had started down without even realising. She almost became used to feeling his touch on her too, a casual grope and squeeze when she was preparing dinner, though Alistair learned to be quick too, darting away from her so that she could not smack him away. Not that she hit hard, too soft on her family, too warm, too caring, though that could very well have ultimately been her downfall.

Olivia didn't stop her son from teasing her, from treating her as someone who might very well be up for sating his needs. She could have, of course, but maybe there was something in her too that was lonely, trapped in the bunker without anyone there to love, her husband elsewhere, having left a long, long time ago on an expedition where they did not even know if he was able to come back to them. It was not something that any of them spent long dwelling on down in the bunker, not when the grind of day to day life and living called them on, more and more.

Alistair, however, was feral and predatory, trembling with energy, cooped up for too long with only his own paw to satisfy his needs. And that simply could not be tolerated, not as he stalked her through the clunky corridors, sharp angles of the bunker heralding the turning of a corner, the quarters that were spread out down there, electric lights buzzing and flickering where they needed tending to once again. Yet that only gave his pursuit even more clarity, shivering luxuriously, his cock out and hard, snarling softly, though Olivia did not notice him behind her, coming for her, entrapping herself without even knowing.

"Alistair?"

She only became aware of him when Alistair cornered her in her bedroom, the sight of his hard cock stripping her breath from her lungs, taking an uncertain step back. The Vulpiri snarled, showing his teeth, yet there was too much frenetic energy in him to hold back, to take it slow, lunging, the world speeding up around him as his purple furred body lashed through the air.

His mother squealed and tried, ineffectively, to push him off her, but it was hard for him to do anything but to take her by that time. Alistair growled ferociously, seeing only her body, her plump curves, everything that her body could do for him, absolutely everything and more that he had lusted for. Sexual energy and tension had been held back for too long, to the point that the only option it had was in explosion, rushing forth, Olivia whimpering, arching her back, trying to worm and wriggle away from him even then, though the moment was already long gone past the point of no return.

The rent of fabric tearing, her skirt cast aside. Alistair's growl pouring over her, sending shivers of less than sweet submission through her. Dimly, she thought of just how like his father he was, just in a different body, and maybe that was what gave her the moment of pause to allow him to push over her, his trousers around his ankles, her bare buttocks pushing back against him without thinking about it.

But his cock did not plunge into the soft folds of her mildly wet pussy, for her body could not help but respond, mind awash in emotion, twisting and turning. Oh no, it was aiming for something much higher, his shaft plunging into her backside instead, driving deep and deflowering the bud of her tail hole for the very first time.

"Ohhhh!"

It was not a moan of pleasure as she panted heavily, clawing at the bed, half pinned over it, one of her hind paws down on the floor and the other on the low mattress, the position awkward. But it was never meant to be soft and smooth as her arse was fucked rampantly, her son snarling as he rammed into her, so lost in the moment that even Alistair could not have stopped himself if he'd tried. His mother's shudders and swallowed up groans told him something even as he took the dirtiest, least clean part of her body, thrusting and grinding like a fox possessed, as if there was nothing more left for him, not in that moment nor any other.

Olivia howled under him, his knot swelling, for Alistair could not hold back, not when he did not need to. It was his mother who had let things go for too long, repressing her desires, all alone in the bunker but for her children. The vixen under him grunted deep in the back of her throat as he rammed in, grasping the back of her neck, nibbling and licking, though it was his lust that consumed him more than anything else, plunging his dick inside her tight rump while the need to cum swelled through him.

His knot grew, locking them together, the pleasure enough to make his head swim, hips rocking, grinding, coaxing the last drops of ecstasy from his body in the moments before climax, though to hold back any more would have been a crime in itself. Yet his mother was tighter around him, not only the knot, everything rising to a throbbing crescendo down in the dankness of the bunker, the sheets rumpled and bunched up beneath her half-naked body.

Yet her scream was what forced him over the edge, his mother getting off on his dick while her pussy squirted messily, nothing to plug it up, messy and sordid and everything that a young fox like Alistair could have hoped it'd be and more. He could not thrust hard and fast with his cock locked into her, bliss pummelling him, but he did all he could, ramming every inch that he was free to move, spending spurt after spurt of virile cum into her tight arsehole.

He stayed there, gasping for breath, heaving over her, nuzzling into the back of her neck, inhaling the scent of her, the sweat clinging in the air, the musk of them. Oh, Vulpiri could not help but exude a particular kind of musk, the aroma of soured apples rising from the body while sour lemons and copper came, ever so faintly, from her plundered tail hole, though it could never be expected to be the cleanest of holes. That was the scat that caused that scent, yet being clean, perfectly so, was not the point of it, not as he spent every drop of bubbling, fizzing cum he had to give, hips rocking, grinding into her backside to get every sliver of pleasure that was to be afforded to him.

Alistair grunted, pulling back, his knot keeping them together even as his mother helplessly looked back at him, a whimper on her muzzle. Olivia panted heavily, tongue lolling out, but the vixen had nothing more to say to her son, nothing to hold him back from, her body trembling with a strange kind of arousal that she could not explain, even if everything that had happened was wrong. Yet how could something like that be wrong when it felt so goddamned right too.

Maybe it wasn't for her to work out right then and there, not as something hot filled her, her son taking the raunchy dirtiness of the act to an even greater height, panting as he spent his bladder inside her too. Although the tiny nuances of such a filling could not be felt, the burgundy Vulpiri could not deny the connection there, fragile yet growing, her son so hot and randy and wanting to fuck her so badly that he'd taken her arse...

Olivia shuddered. There was embarrassment there, twisted up in something more, her pussy wet from something that she would not put words to. Filthy sex, her son's cock... There was no way for her to understand it, but neither did she have to while her son's knot kept them tied, secured together while he filled her to the brim with piss, his knot keeping it from leaking out.

What neither of them knew, however, was that there was an even dirtier little vixen (well, perhaps not so little with her plump stature) outside the door, her jaw hanging and her paw shoved between her chubby thighs. Amber worked furiously over her own pussy, though there was a part of her that snarled, that wanted to dive in there, to snatch the brother who was hers away from her mother. That bitch of a vixen must have wanted him all for herself all along! That's why she'd never stopped him from groping her!

Amber, however, could not help herself, panting, clapping another paw over her muzzle, keeping herself quiet all so that she could watch for a few moments longer, as long as possible. Her brother was balls deep in their mother, his knot pulling at her pussy, though he could not yet free himself as his mother wriggled under him, whispering to Alistair. Still, it was something that Amber could not quite catch.

She peeked, ears twitching, though she still strove to be as discreet as possible, wanting to watch, not to be discovered, emotions writhing with discontent. It should have been her that he was fucking! Yet if that was to be the case, why wasn't she rushing in there instead of standing there masturbating, her breath catching as she got closer to the edge? Amber couldn't get off without revealing that she was there, reluctantly sliding her dripping fingers from her pussy, though the scent of Vulpiri scat, as faint as it was, tickled at her nose, the raunchy musk stoking an even deeper need in her.

As she backed off, eyes glowering in the dim light of the corridor, she vowed to have her brother.

Through any means possible.

He was too hot for her to resist.

*

Olivia didn't know what to make of her son, afterwards, though he carried on as if things were normal - expect for pursuing her multiple times a day, of course, to ram his cock into her arse. It didn't matter where they were, in a bedroom, a corridor, at the table, over the sofa: he would have her anywhere he pleased. And he knew it too, feeding off her natural submission, the distant and aloof mother that he had known transforming into something new.

She didn't know what she was to be, who she was to be, not yet, but that would all come in good time, stifling her moans into a pillow on the sofa (something that had been sewn too, of course, by her). Olivia didn't want to be heard, but her son didn't care about any of that as he thrust into her tail hole, plundering her backside with thrust after thrust, spreading her open and forcing her to take his dick time after time again.

It was rough and it was coarse and it was crude and it was shameful. Still, his mother did not stop him doing that, something that Alistair was more than set to take full advantage of. After all, if she did not resist or tell him no, not even once, didn't that mean that she wanted it? Maybe that could be so, though Olivia still had to come to terms with her wants and needs, everything twisted and confused, even liking the dirtiness of her son pissing into her backside. That was wrong, so very wrong, but she loved it too, shuddering through orgasm, her pussy squeezing down around nothing, hiding how much she liked it even then.

Days turned into weeks, though they never quite caught Amber watching them, the chubby vixen too sly and discreet, though her plans were in action, all in the background of everything. She would not have wanted to hold back and, of course, it was obvious what her mother and her brother were up to, even if she had been completely clueless and had not caught them in the act that first time. The scent of sex and Vulpiri musk clung to the bunker, only exacerbated by the fact that hardly any of them ever ventured outside, instead choosing to hunker down and wait it out. Sometimes, it felt like that was all they could do, thus it was the done thing.

The feel of his cock plunging into a tight arsehole... Oh, it was the best, but perhaps not quite the best thing ever, not the thing that would have him grunting and growling and snarling for more. He took it but he craved something more, more devout passion still, the dirtiness of the act not excluding him as he took his mother more savagely than ever. It was a wonder indeed that he had ever been able to hold back his sexual energy, the fervour that made him who he was, the fox grunting as he slammed in, driving her, that time, into the chilled fridge, where most of their food was kept.

"Unff... Yes... Fuck... Ergh..."

He didn't have to be eloquent in the heat of the moment, tongue lolling out, the squirting mess of her orgasm splattering around her inner thighs, the scent of her arousal and musk clawing at his nostrils, demanding attention. The stink of it clung to her, though it was intoxicating for a Vulpiri, making him want her even more. His knot was already half-swollen and hard, extending out of his sheath with arousal, but it would only swell to its full size to keep them together through dirty cumming when inside. Otherwise, something like that just would not have fit into her tight pussy, her folds squelching lewdly as he pounded her arse.

Her body was there for him to take, the flicker of a red fur around the corner heralding his sister backing hastily out of the kitchen, though Alistair could still hear her there, the slop of her pussy, her fingers plunging inside. He could not help it, growling, slamming his knot into his mother and climaxing right then and there as he filled her arse once again with cum. Fizzy cum bubbled and churned inside her, kept right where it was supposed to be. His knot stayed hard, his orgasm rolling forth, pump after pump spilling from his nuts while another part of him yearned for a dirtier, messier kink still. His cock, of course, would be smeared with a hint of her scat when he pulled out, but that was all in the nature of backdoor play, at least as he wanted it to be. It wasn't as if his mother had voiced any kind of complaint as to the messiness of it all either.

His knot popped out, but not before he'd hosed her down inside with a liberal dose of urine, practically treating her as his own kinky toilet. The trickling drips of piss were none of their concern as the lust of the moment ploughed on, dragging them with it, his mother grinding back as if to get even more inside her. Though who knew what was going on inside her head, her body more than big enough to throw his form off if she'd wanted to, yet she submitted to him pinning and fucking her all the same.

As Alistair drew out, he let the last dribbles of piss leak over her tail hole, smeared around her pucker, urine mixing with a hint of scat. It was not as "bad" as if scat play had truly been delved into, yet gave him a shivering nuance of the naughtiness of it, the uncleanliness bringing a rise of need to him, despite needing a break for his knot after cumming the once. It, at least, served to let her recover a little, even as his mother's dirty craving for his dick grew and grew.

Eventually, however, Olivia didn't know any other day except for one where she submitted to her son pinning her to take her arsehole. So much so that she sought him out when he did not come for her.

"Do you want to fuck mummy's arse?"

She posed a little jauntily, dressing more skimpily than she had before, more of her thick legs showing, her clothing easy to pull aside to get at her tits and backside, as he pleased. She was still modestly covered up, but there was a noticeable difference as her son sprawled back on his bed, eyebrows raised, a certain kind of smirk pulling at his lips.

"Maybe..." Alistair evaded the question, quelling the need within him even as his heart pounded, skin prickling with tantalising heat. "But no. I want to fuck your pussy, cumming inside... It should not be just your arsehole that I own."

His eyes glowed, tongue lashing the side of his muzzle with barely restrained need.

"So, give it to me!"

She panted and shook her head. No... No, her backside was dirty, but her cunt was too much to give him - he was her son! Yet there was still only one course that Olivia could follow down in the bunker where the rules and laws of society had ceased to exist, everything that they had known becoming something different, something of their own design.

Maybe it was better that way.

Alistair dragged her back onto him so that her backside faced him, his mother whimpering, quietly passive but not giving him exactly what he wanted. But he could take control, licking his lips with a lewd, wet smack as he plunged her down onto his dick, the position allowing him to guide and control her as her legs went to either side of his, straddling his hips. His cock, however, plunged deep, right up where it belonged, his mother whining, high-pitched, as she was forced down onto his dick, though there was little force to be had about it as her pussy was finally filled.

The Vulpiri vixen howled, climaxing hard, her pussy squeezing and gripping his dick while her son claimed her, filled her, his bare length holding connotations that they would only come to recognise later. The tapered tip drove deep up into her, though it was perfectly designed to wedge into her innermost barrier - something that would have been painful for her if their species had not been perfectly designed to take it. He heaved and panted, scrabbling to thrust up into her, but despite all the sex he'd had with his mother of late, Alistair was not all that experienced himself, not as much as, perhaps, he claimed to be.

But that had no matter, not between them. His cock plunging into her was all that he cared about, exulting in taking her pussy for the first time since his father, slamming in hard and fast, regardless of how the sheets twisted and pulled at him. He could only thrust, more and more, driven by raw need alone, a snarl rising in the back of his throat, unable to hold himself back even then. Not that he had to hold back, now that his mother had completely and utterly submitted to him, wanting him to fuck her dirty hole, to have him, even if she did not quite understand why. Understanding of lust could come in time.

Her pussy was hotter still, clenching wetly around him as she squealed and squirted in orgasm, no longer even trying to hide her passion in any way. There simply seemed to be no need for it, no need at all, not as her sex squeezed and rippled around it, her body knowing just what it needed to do to coax every dirty drop of cum he had in him forth. It would milk him and massage him of his fizzy seed, as erratic as the twitch and pull of her sex was, though the tightness was indeed delicious, his knot plunging inside with a ragged howl of lust that did not sound as if it came from him. Even Alistair was uncovering more parts of himself in filling and fucking his mother.

Orgasm would not be held back and his mother losing control of her bladder - it could have been grossly deliberately, erotically so - as the sordid nature of the act itself ramped up tenfold. For, as he filled her with spurt after spurt of thick cum, her pussy squeezed around him, giving him nowhere to go but to let her piss soak the fur of her inner thighs and even his crotch too. The rankness of the aroma clawed at his nostrils, yet it was one of the most alluring things to a Vulpiri, something that had Alistair licking his lips, again and again, softening his nose with the wetness there so that he could better take in the alluring scent.

More... He blinked through a haze of lust, energy slipping from him, drifting on an afterglow, though he could no longer find the presence of mind, that time, to relieve himself into her pussy too. Maybe another time. Another time when his skin was not tingling while his muscles ached with passion, with lust, the devoutness of orgasm coursing through him. His knot swelled and throbbed, tying them together, panting so heavily that he barely seemed to manage to get any breath at all into his lungs.

All the while his mother was there, her legs trembling, helpless, broken to his will, wanting only him, her son, the fox that she had raised and yet had to take her then, as a fully grown adult. He was no longer a boy that she had to look after but one, perhaps, that could care for her too - even if that caring and protecting started with greedily taking his leave of her pussy and arsehole every single day for the rest of their time together.

Olivia shuddered, licking her lips. She could only hope.

Only after he'd filled her pussy with his spunk and pulled out did he finally taste her, slithering his tongue wetly through her arousal, showing her just how turned on she'd become from him fucking her. It was the ultimate humiliation, the most carnal of all, though neither did Alistair mind cleaning off her dirty tail hole either, wondering if she had left herself particularly stinky and musky down there just for him. The scent of her need was particularly strong and he slurped up deeply into her cunt and her tail hole alike, tongue insistently worming inside so that the greedy young fox got the best of both worlds, entertaining himself in sordid depravity.

It was all he craved, all he needed, and he lapped deeply into her, tasting her musk, the dirt of her tail hole. The coppery undertone highlighted the lemon of her scat, but it was not overwhelming, not in the slightest, a little slick on the tongue where she was not cleaned as well inside as she could have been, yet that only made it all the better for her son. He wondered a little too if shed worked out how much he liked it, the smell and the taste of it, how it clung to his dick after fucking her, but it didn't matter if she had or had not, not to him. He got what he wanted either way.

"You bitch!"

It startled them out of their lustful reverie, Alistair glancing up with his nose buried under his mother's tail, though it had already been flagged up well out of his way to enjoy her. His sister heaved for breath, fat rolls shuddering, but he wasn't about to stop on Amber's account, his sister bedraggled and whimpering furtively through her rage as if that was going to help at all.

"You can't fuck her - you're supposed to be for me!" She screamed, fists flailing, though Amber didn't know how to fight, how to use her body even then to defend herself. "Stop stealing my brother's cum! He's mine - you bitch!"

Yet even her insults were not as strong as perhaps the younger vulpine would have liked them to be, the Vulpiri affected by the heavy scent of musk in the air. She could not help but suck in breath after breath of it, simply needing breath in her lungs, moaning, whimpering, shaking with pent-up rage.

"You can't fuck her and forget me!" She pressed on, lips trembling so badly with the want of growling that it was more difficult than ever for her to get words out. "He's mine... All mine... He can't knock you up - it's meant to be me!"

She howled, deranged with lust, but her brother shuddered, struck with passion again, his body recovered enough with all the time he had spent eating out his mother's pussy and arse to go again. It may have been an act of riling her up or an act of defiance, but it took only a moment for Alistair to shove his plump mother onto all fours, her backside perfectly positioned for him dick all over again. Olivia tried to placate Amber all over again as her pleading cries fell on deaf ears, the younger Vulpiri flailing, fighting against nothing at all, for it was her brother who decided the course of action from them on out.

"You're right, sis," he laughed, a twinkle in his eye that begged trouble. "Maybe I should have been thinking about breeding a fox... But knocking mum up comes first!"

He could have stopped, but it was too much for him, too keen to wind up his sister. After all, they would always be brother and sister, despite her lust for him, and Alistair saw another fertile vixen in need of breeding, even if she was fatter than their mother, fat thick around her as she trembled with anger.

His cock plunged home into his mother again and he wasted no time at all, even as a horrified Amber rushed in, slamming into her, his knot pushing out, growing, swelling, as if his body suddenly sensed the lust and urgency behind his strokes. He had to fuck her, had to breed her, had to ensure that her pussy was so well-seeded that there was absolutely no way that she would not come out of such a liaison without her womb brimming over with his cum. That meant that he had to go deep, snarling, his sister pulling at him, but he was stronger than even her, Amber weak with fury.

She had to do something though - anything! She had to stop him from sealing the deal from knocking her mum up, though her mind was too addled with lust and musky arousal to think straight. Her body moved as if through thick sludge, wading through the odd passion of the room, breath catching, pulling anxiously at her lungs. What a cum-stealer her mother was! She wasn't supposed to take it from her! Did she even know how badly she wanted her brother? Probably so, for Olivia had already forgotten her daughter as the vixen lowered her head, on all fours, submitting to her son in all ways, wanting only his cock pounding her ruthlessly, again and again.

With his knot inflating inside, ensuring that he could not and would not pull out, Alistair howled out his victory in orgasm, the dirtiness of the taste of his mother lingering on his muzzle making it all the better for him. He knew what he needed and he took it whole-heartedly and lustfully, having grown increasingly comfortable with his mother's body, the shape of her curves, how she humped back against him when she was becoming just a little bit more desperate. His eyes glinted, some part of him that he had not known existed delighting in his sister's fury, how she was trying to stop him, even then, turning around and backing up as if she could get him to fuck her.

"Come on, bro!" She howled, stamping, trying to convince him through any means possible, her pussy swollen and dripping as if she could not stand it any longer. "Fuck meee!"

Her mind swayed and turned with lust that was not to be controlled as she groaned and shoved her fingers up into her pussy, straining to masturbate, pummelling her cunt with three digits as the embodiment of raw need. Despite her shirt, her stomach rolled down against her thighs as she bent over, her size all on show, the thickness of her arse ground back against her brother as if she was trying to get him inside her right there and then. Amber wasn't thinking straight, not even realising that his knot was stuck inside their mother already, that there was no way to get his prick out of their mother and into her. There was simply too much going on, all at once, for her to keep track of it, whimpering, half on the bed, masturbating furiously, lost in a moment that had not truly been meant for her.

Yet the vixen pushed on into it all the same as he fucked their mother, knotted, taking longer to cum that time around even when there was no going back. His cock slammed into the older vixen while Olivia howled out orgasm after orgasm, Amber whimpering and whining, twisting, gyrating, trying anything to get some kind of relief. Yet masturbating was all she had while her brother's attention was wrapped up in their mother, fingers grinding into her sodden pussy, folds squelching around her fingers, passage tight and yet yielding, both at the same time.

She had to have him, had to have his dick, but her panties were only yanked down enough to bare her pussy, her need too high to hold back. His sister squealed through furious climax, spraying and squirting all over the bed, even marking Alistair's thigh, though that was not enough to stop him from thrusting and filling their mother. With his knot engorged, he finally burst over the edge into climax as spurts of cum poured forth, ensuring that there was no way that their mother could leave such a liaison without being knocked up - exactly as he wanted it to be.

Amber, however, squirted her mess onto him, the bed, their mother's fur, not caring for the mess of arousal and urine squirting forth. It was dirty and it was meant to be, all part of their mating rituals that Vulpiri could pick up and put down as they pleased, though they could never pull back entirely from the liking of dirty play, as ingrained as it was into their psyche. Amber ripped off her panties, soaked with urine and a hint of her "cookies and cream" like scat to mark her territory, flinging them balled up on the centre. Her brother looked on, tongue lolling out, though his energy had simmered down, at least for the moment, enjoying the rolling pulses of orgasm as he filled his mother, imagining, lustfully, just how her belly would swell with the evidence of his virility in the months to come.

He stayed there, licking his lips, lust rising, though he had to have time to recover too, sprawling and stretching out on his bed while his mother, his knot having softened, went to get dinner. Time seemed to have no meaning when he was fucking her, something that he lusted for more, whimpering and grunting, eyes intent with the burning need of it all. One of his family members would not be enough, though it was hard for him to know that, to truly understand, even after so much already had come to pass. Maybe that was the course of things in the bunker, twisting things to sordid, filthy whims and wills, letting his cock rise again to full hardness once it was good and ready.

Then and only then did he seek out his sister, licking his lips hungrily, though to find her in her room was not unusual. The lingering scent of her panties, used and dirtied, clung to his nostrils, but they'd been left on his bed, his sister on her bed, groping her fat tits, mostly naked bar a shirt that had been yanked up to expose her tits, nothing on her bottom half.

She froze as her brother stood in the doorway, looking her over with a glint in his eye that made her heart pound, the sheets under her soaked with a mess of need already.

"What do you want?" Amber snapped, the bite in her tone impossible to hold back. "You done fucking mum already?"

Alistair considered her, his hard shaft throbbing, lust rising, curling deep in the fit of his belly. He could feel it even then, the need in him, what made him want to close the space between them and fuck her as if she was nothing more than a hot hole to breed. The fox took a breath.

"You want me to fuck you, don't you?"

He said it as if it was a question, yet a question that only had one answer. The cocky fox with a tilt to his head knew he did not need to ask it, not as his sister panted, fingers rammed up into her pussy still, wide-eyed and staring as if she didn't know what to do, even then.

"Yes..." She whimpered, barely able to get the words out. "Oh, fuck... Bro... I... I want..."

But he already knew what it was that she wanted, even if it was hard for her to say that, harder than either of them could have ever imagined. She rolled onto all fours without thinking it, for conscious thought was the enemy of all, presenting herself for him on all fours with her tail raised, a needy whine clawing its way out of her throat.

"Present yourself!"

He barked the command, though there was giggling glee behind the words, not much of a leader but one who knew what he wanted. His sister jumped and groaned, grinding back onto her paw all over again, showing him the depth of her need, her depravity, how much her swollen pussy truly needed it, even then, hardly knowing what she was doing. Her brother simply brought out that side of her in a way that she did not understand, could not understand, but she had to try, had to lust for it so very keenly all the same.

She was presented, exactly as Alistair wanted her to be, grinning madly, smirking down at her as he knelt on the bed behind her. The roundness of her backside drew him in and he caught the tremor that went through her, even then, the tip of his cock prodding at her pussy.

She tensed.

"Ah..."

He wouldn't want to fuck a fat fox like her, would he? Her head spun. No, he'd chosen her mother, hadn't he? Yet that was not for her to decide as he slammed in, delight washing through her, her heart lifting as she chuffed out a sharp exhalation of air. Amber's heart pounded, beating too quickly, though she didn't hold back her glee as he fucked her, harder and faster, slamming into her as his half-swollen knot popped in and out of her sloppily soaked pussy.

"Unff... Fuck, yes..."

Alistair's eyes gleamed as he powered in, the slap of his hips on her plump backside rolling through the room, though it was no good trying to hide anything. It barely seemed as if they had begun when his mother appeared again, cum trickling down her legs, completely naked, her eyes wide with shock.

"Alistair! You can't breed her too - think of what'll happen! You'll make her pregnant! We can't..."

But Olivia trailed off. Even though it was "wrong", on a technicality, there was so little to be had in the post-apocalyptic world that those lines, like an old song that no one much had liked, had become blurred. The edges were shaky and shuddered even while she strove, weakly, to drag her son from his sister, her fingers trembling and ineffective at best.

Olivia may as well have not done anything at all, for all the use she was in stopping him from grinding into her daughter, not that Amber wanted anything any different. Her fat jiggled and rolled with every thrust, delighting where he was, losing herself in orgasm after orgasm, passion coursing through with the pounding of her frantically beating heart. She cried out for her brother while his aroused knot popped in and out of her, not yet swollen fully to lock them together, her ears more submissively splayed out to the sides.

Olivia, however, knew when she was beaten, or maybe it was her submission to her son already winding through her, telling her what to do, what was the only course of action she could take. She was there for him, her son and her daughter, and maybe it was only natural for her role to shift, however discreetly, over time. Whimpering, she nuzzled in, intoxicated by the scent of them, tasting her daughter's musk on the air more strongly than ever, though it was always there, trembling between them. Sex only brought a rise to it that had her lapping her lips, drawn in more and more as she submitted to the new head of the household, the bunker that was their home, and nuzzled at the join of their bodies.

"Oh, yes! Yes, yes, yes!" Amber howled. "Fuuuck meee!"

He slammed in, his knot swelling inside her, locking their bodies together so that there was only one place for his seed to go as it filled her, spurt after deliciously fizzing spurt pumping forth, the young Vulpiri not able to control himself. It was a time of change like no other and there was no going back from fucking his mother and sister bareback, his seed pouring into them, erupting directly into their wombs, ducking into the neck of his sister's cervix, designed for such things. He shuddered, panting heavily with a roll of his shoulders.

"Fuck, that's hot..."

And that was true, even as his mother cleaned him and his sister off, lapping over them, fussing with them, adoring them but in a new way, a way that would bring them all closer together than ever before.

There was no stopping the course of events as, that night, all slept in their respective bedrooms, even if there was not enough fresh water there to wash the musk and stink of one another from their coats. Everything had changed, so very swiftly, and Alistair licked his lips, eyes alight from all that he had, final, dared to snatch up for himself.

*

He didn't stop fucking his mother and sister either, not even as their monthly cycles came to a halt, no longer going into heat and their bellies, slowly, so very slowly, growing with the promise of new life. There was no one there, of course, to judge them for such an act, though he nuzzled warmly into his mother's stomach as it became a little more obvious, rounded out, knowing with a delicious shiver of pleasure that it was his offspring in there. Breeding was oddly more alluring than even Alistair had thought, but it was still a time of new experiences, despite the twist in the fate of the world they lived in.

His sister groaned, cleaning his cock after he'd fucked his mother's pussy and arsehole, delighting in his musk, though she'd been fed up more by that point so that her pregnancy was not even noticeable at all in the early stages. He teased her and mocked her fatness, telling her how big she was, how her fat rolls gave him something, "love handles", to hold onto, though she kept eating and eating, growing in more ways than one.

Olivia had, in a way, tried to hold him off from ensuring that she was impregnated - just in case that first time, or second time, or third time didn't take. The vixen ground her arse back at him, spreading her rear cheeks with her paws while she submitted to him, trying to show off her body as much as possible, to make her tail hole look like the more appealing option. She was older and it should have been more difficult to impregnate her, panting and whimpering, the submissive, lowering part of her wanting it all the same. After all, it was what her son and her dominant fox wanted, so what, truly, would she ever have done against him for that matter?

"Don't you want to take mummy's tail hole?" She whined, wiggling her butt back at him as he folded her over the arm of the sofa once again. "You know you want to, darling... Ohhhh!"

But Alistair had eyes for the succulent sweetness of her plump pussy, grinding into her while his body rumbled with pleasure. He didn't have to ask permission to fuck her anymore, not when it had already been given, and the vixen stopped trying to get him to fuck her arse after it became obvious that she was pregnant. That didn't mean that she stopped taking him up her arse, for that was Alistair's choice to fuck her there, but there was no need to dissuade him from breeding her fertile pussy anymore, regardless. She was already pregnant and, with so much going on, there was simply no going back as another month passed and Olivia sank lower and lower into a strange kind of submission.

They wore fewer clothes still, tits out most of the time, allowing Alistair to hungrily suckle on them, groping and squeezing their bodies whenever it pleased him to do so. Olivia whimpered, letting him fuck her missionary style, though Amber was hovering around, demanding attention, her body thicker, fat lumps rolling and settling on her hips as if her body was forever in a state of growing larger, though it was a slower process. His mother didn't know what she wanted anymore as she submitted to him, taking her mind elsewhere, though his rampant thrusts, popping his knot into her swollen folds, flushed with arousal, would not be denied.

She craved it, losing the sense of her old self and finding something else down in the bunker that was more alluring still, the messiness of it all reminding her instincts of a more feral, more primal time, sometime where they had not had to worry about such anthro needs as Vulpiri. They were an old species, one that had been around for so long that their kind remembered the beginning of modern society, yet her son changed all of that for her, regressing her into a snarling, whimpering mess that only craved his cum.

Never out loud though. Alistair fucked her into screaming, howling orgasm after orgasm, yet his mother was his, even if she never said it out loud. His sister, on the other hand...

Well, Amber's paw, to say the least of it, was always between her legs, even though she was not always fucking her brother. She trembled at the thought of how large she was, but kept herself as busy as possible, her fingers sliding between wet, slippery folds. She was his, yes, but she had greedily claimed him too, the perfect wife, the one that was with him, even if they so very rarely had any need at all to venture outside the bunker. Amber could have talked to others on the radio system or the inter-bunker communications lines, but, well, she'd much rather be gulping her brother's dick into her throat or taking his cock into her pussy.

She didn't let him fuck her tail hole, growling and snapping, still a brat. She would always be a brat, regardless of anything else, regardless of how perfect she wanted to be for him. Her brother let her know how big she was, even heaping extra food on her plate, smirking at her the whole while, but she could not stop him from feeding her up, as greedy as ever. Even though the vixen did not want so much extra food, she snaffled it up, slurping down every meal, the meat that her brother brought in for them, trading and negotiating better than her or her mother, more delicious than ever.

Maybe that was just why he needed to be the head of the bunker, the new household, so badly. It was simply his right, his position, the place that he should have loftily taken for his own so long ago. He didn't want the responsibility, of course not, but he most certainly took advantage of all the perks that went along with being the top fox around there, humping his mother before she was even allowed to use the bathroom in the morning, her pussy stuffed full of his cock.

Her cries echoed forth and his sister scrambled out of the shower, wet and sodden, wanting his dick, squeezing in, forcing him not to knot their mother and fuck her instead. So early in the day, despite not rising all that early at all, Alistair wasn't all that picky about who he fucked, but he did make sure to spank her chubby arse, all to make the flesh of her body jiggle and shake. God, what a shame fest of fat she was, even if she was a fuck fest for him, the meaty folds of her thick pussy swallowing him up too as if her body was slurping down his cock. His cock was just another meal for her to take in, gripping her love handles, the folds of fat rolling down her body. Amber was bigger than ever and he smirked to see it, though there was a part of Alistair that would not have wanted it any other way.

He just wanted to see her grow and grow, how thick she was, feeding her up as if he had any real reason behind it, though he wanted solely to see her reaction, lusting for her. Of course, he only fucked his mother and sister there, not seeing the need or reason to fuck anyone else or seek anyone else at all out, especially as Amber's belly finally became noticeable past the swathes of fat layering her body.

"If you keep eating, you won't even fit through the doorways," he teased her, fucking her hard on her bed, his stomach against the rounded rise of her own, though that could no longer be helped. "You're so big... When did you even start eating so much? So thick, sis..."

It was a taunt and a tease all wrapped up in one, his knot slamming into her, swelling, locking them together for a fizzy load of bubbling Vulpiri cum to spill forth. Alistair panted heavily even as his sister whimpered, torn between two opposing courses of action, even though she didn't quite know what she wanted to do, what she wanted to say. He drew on such strong emotions in her that it was difficult to pull apart one from the other, licking her lips, a growl weakly rolling forth. Yet his mockery of her tamed her words, seducing the edge of her "brattiness" away, all for the pleasure of her "brother-husband". Amber did not, however, need to understand what the young fox was doing to her, if he was pleased with her.

After fucking his mother's tail hole one day, Alistair dropped to his knees, reeling and relishing in her musk. She seemed to smell even stronger as her pregnancy eased on, five months in and obviously round and showing, though she would get even bigger with a full litter of fox cubs very soon. Their pregnancies were like those of many humanoids, though Vulpiri had larger litters than most other species, fourteen to sixteen cubs in a litter. Alistair, however, did not care about that.

His tongue swirled around his mother's tail, scooping up the dirtiness there, though it only lured him in, softened the moment into something delectable. If he had not been able to savour her essence every day, perhaps he would have replayed the moment repeatedly in his head, how it felt to wriggle his tongue inside her dirty backside, that sourness, the bite of metallic copper nipping at his tongue. But, as it was, Alistair could have her dirtily or cleanly whenever he pleased, thus simply enjoyed.

Filling her with his piss, however, was a kink that he particularly enjoyed, Amber whimpering and pawing at him, groping her huge, sagging tits as if that would get his knot to deflate, while he rested, balls-deep, within his mother's backside. Streams of piss pumped forth after his climax, the young fox exhaling softly while he relieved himself, the stink of his mother intensifying, though he swore that, sometimes, she relieved herself too while he was tied to her pussy. She certainly squirted, the mess of her juices clinging to his fur, though he had her clean that up too, when it pleased him, rendering her muzzle a stinking mess, fur matted and clumped, her eyes desperate.

She was a pet to him, though Alistair did not have enough experience, not in that kind of play, to put a name to how he felt about her, at least not out loud. His sister whimpered and whined and, as she caught his muzzle in a desperately sloppy kiss, he claimed his sister's lips with his own, teeth gnashing against hers, his tail lifting dominantly. To have not one vixen but two, his very own family... Alistair shuddered with heated pride, his knot throbbing inside his mother's cunt. There was nothing else that he would rather have had.

Their stomachs grew bigger and bigger in the last couple of months of their pregnancy, Amber struggling to walk a lot of the time, the one of them that had faced the greatest change to her centre of balance. She groaned, tongue hanging out, leaning against a doorframe for balance, yet she would still insistently make her way to her brother's bed to mark her territory, his wife, his pleasure-fuck, the fat vixen that he'd take every day while she made sure her mother knew that he was really hers and hers alone. She'd piss on his bed, squatting dirtily, though the urine seeping into the sheets would often send her into a frenzy of need, masturbating furiously until the reek of it became enticing, enhancing her need even further.

It was a vicious cycle but one, in a way, that suited the family well. It was their own kind of way of living through something so truly horrific that it did not bear dwelling on, even at that time. It was not for them to wonder and worry, locked up in the safety of the bunker, his mother panting as she walked, though she still took care of the family mealtimes, like the good mother and pet she was.

Before they, finally, gave birth, Alistair took both rampantly, for even he knew that they would need time to recover afterwards, filling them both over the table straight after dinner. The female foxes moaned and groaned about how full they were, Amber's stomach heaving more than her mother's, yet neither of them had any standing at all to tell Alistair not to fuck them, not to slam his knot into each of them in turn and clean up both their pussies and tail holes afterwards. All their holes were for him to fuck as Amber's bare tits squashed down over the wooden table, the grain of it pressing up to her breasts, muzzle agape in a moan, and the fox would have them, again and again, as much as pleased him.

"Ah, yes... Bro... Yes..." Amber panted heavily, the strain of his cock in her backside, dirty and unclean and yet perfect exactly as it was, making her shudder, her stomach heavy with young. "Yes, fuck me... Cum inside me..."

Of course, Alistair wasn't going to have it any other way, not even as she clung to the table, the old wood creaking, his mother sitting there ready to help with her tongue, swirling it around the join of their bodies, regardless of the lingering sourness of dirt there. That didn't matter to any of them, regardless of all the laundry that Olivia ended up having to do. She would care, as the mother, as the pet, while his sister satisfied him, taking yet another load of cum. She'd said something, once, about wanting all his cum to ensure a healthy litter of fox cubs, but he did not care to tell her that it had no bearing once she'd been knocked up. It no longer mattered to Alistair.

Could a fox like him have had it any better in life? The bunker had been the start of a new life for him, a better life, and there never was any going back from that.

Smirking, rolling his hips against his sister while his knot tugged at his tail hole, Alistair panted heavily, eyes alight with domineering glee.

As soon as they gave birth, he'd knock them up again, his harem of two slutty, lusty victims, begging for more. He'd never need anything else, their days happy and long, flush with sex and rolling moans.

He'd never need to ask for more, when he already had all he wanted.
