#15 of Commissions

A commission for Lynneth

It was fun putting an unusual twist on the ol' mom/son kink. Originally I wanted to have the mom and son stuck with each other during a zombie apocalypse, but trapped together on a tropical island certainly made for a sexier setting.


All characters depicted in this work of fiction are of legal age of consent.

Not even if you were the last woman on Earth.

Isn't that how the phrase goes, lads? Isn't that what you'd say if your sister crept into your bedroom in the wee hours of the morning, hungry for your cock? Wouldn't that be what you told a cousin, or God forbid, your own mother if either went into heat and you were the only man in arm's reach?

Ethan liked to think that would be that easy. He liked to think there were lines of civility he would never have to cross, no matter how horny he might be.

Unfortunately, as he quickly came to find out, an uninhabited little island in the middle of the Pacific wasn't exactly a civil place.

Perched on a rocky outcropping, Ethan watched the shimmering lagoon waves below with care. In his right hand was a long stick sharpened into a slender spear, his free hand held out for balance as he stood frozen and patient. The equatorial sun beat his white fur from above, with a light sea breeze bringing some much-desired relief from the heat. It brushed across the sleek coat of fur covering the anthro husky from his head down to his bare feet. Dressed in naught but a tattered pair of board-shorts, Ethan looked more like a cat staring into an aquarium than a canine waiting patiently for the next meal to swim by.

A shadow skittered across the soft sandy bottom of the lagoon. Ethan locked on with practiced precision, then leaned in slightly and smoothly threw the spear.

There was no arc to the throw, he wasn't going for range. The target was only a few metres away, and with hardly a splash the spear pierced the surface of the water and slammed into the fish just below.

A few moments of scrambling and splashing later, Ethan waded onto the sandy shore, spear resting on his shoulder and a meaty tropical fish in his hand. Gathering up the other fish he had caught earlier, Ethan wrapped the catch into a few palm leaves and made the bundle into a sort of satchel that he strung across his shoulder.

On top of his spear and a makeshift pack, Ethan had spent these past months making everything from scratch. Everything from utensils, to string, down to simple bowls and even shelter had to be made out of what was available on the island. He'd circled the island at least twice in search of other survivors, or perhaps even some form or civilisation.

Alas, it seemed they were alone, surrounded by untold miles of ocean in every direction.

Following the shore to the rockier south end of the island, Ethan had a moment of mental betrayal. Reminiscing like this brought up a horrible memory of when their plane went down. He had been flying home with his mother when something exploded. The whole craft had gone down somewhere in the Pacific, and the next few moments had been a mixture of choking darkness, bubbles and claustrophobia. Ethan didn't know how, but he'd somehow managed to drag his mother out of the wreckage with him and paddled to the surface where they desperately clung to a piece of floating wreckage in the buffeting storm.

The next day they'd woken up here. Washed up on the shore of this tropical island. Alone.

Rubbing his eyes, Ethan sighed. It wasn't all doom and gloom. The island was big enough to have an easily sustained eco-system. Lush vegetation, sandy shores, fresh water flowing from the central mountain with reefs thick with aquatic life all around. Under different circumstances, this would make for a kickass holiday resort.

Additionally, there were populations of small rodents and goats all over the island. The most dangerous things on the island were perhaps the monitor lizards, though they stayed inland and avoided the coast most of the time. When it came to survival, the island provided them all they needed.

And at least he wasn't stranded alone. He was with his mom. Though time was beginning to tell if that was such a good thing.

The caves housing their camp came into view and something in Ethan wanted to turn him about and march him in the opposite direction. It wasn't that he disliked his mother. Rebecca Wolsey was perhaps the greatest companion Ethan could ask for on a deserted island. It was just... difficult.

Months away from civilisation - away from women in particular. Now the only nearby woman was his own mother. Add to the fact that she was incredibly hot. Trim and athletic, with a nice pair of C-cup breast, long slender legs with wide hips aching to be touched...

Ethan shook his head, drowning out the wandering thoughts considering his mom as hot. That was just the extended strain of sexual frustration thinking. He felt some tension in the front of his shorts for a moment, but after a few long breaths managed to bring his erection under control again.

He'd seen his mother on the poolside before. He'd seen her nude plenty of times. And in the past he would have been impassive. But now, isolated from the warmth of a woman for two months, knowing explicitly what treasures lay beneath Rebecca's bikini, it was driving Ethan insane.

Swallowing hard, Ethan did his best to flatten the immense bulge showing in the front of his shorts and approached the cave.

The cavern was elevated about three metres off the beach and was only maybe a dozen metres deep. It was more like a giant had taken a bite out of the island, leaving a large rocky cropping. But it was well sheltered from the elements and elevated just enough so predators didn't come scrambling in during the night.

The small campfire Rebecca tended to helped in that regard too.

Humming to herself, the woman threw a few more twigs on the fire, then went back to maintaining the palm leaf tarp covering the sleeping area. She'd padded the makeshift beds with more soft leaves and fibres stripped from coconut shells earlier. And now using a bit of string Ethan had made she tightened the large palm leaves, then used a knife to cut away the excess.

Finishing up, the husky looked down at the knife Ethan had made, like everything else in their camp. It was a piece of the aeroplane that washed ashore, and Ethan had battered it into shape and sharpened the edges to serve as a knife. Simple but very effective.

For a moment she was immensely proud of her son... and regretted the thought for an instant.

Rebecca put aside the blade and put her hands on her hips. Her eyes fluttered shut and she took a few shuddering breaths, knees shaking a little as a fire ignited between her thighs. She had to bite her lip, nearly hard enough to draw blood to quench the sudden flare of desire for a strong man rising within her.

She'd been in heat for a nearly a month now. And with no medicinal suppressants to hand, things were really taking a toll. Her body craved a desirable male between her legs so desperately, she was finding her mind wander more and more to thoughts of bending over for her own son and begging him to rut her silly.

Though thirty-nine years old, Rebecca's age didn't show. She had the figure of a woman half her age, standing five-six in height with a trim, curvy figure and long slender legs. She liked to keep in shape, and it showed in a toned abdomen any other mother would kill for after her first baby, and healthy, white fur. The only tells were a few strands of silver at the temples, though the rest of her wavy chestnut hair drowned out the greys.

Her sleek curves were barely left to the imagination. With most of her luggage lost to Davey Jones' Locker, she was left with the tattered remnants of the dressy black miniskirt she'd been wearing when the plane crashed, and an ill-fitting bikini top that had washed ashore. Her panties were missing, gone like her stockings and shirt to make some essential survival supplies like water-filters, bandages and other binds. It was too damn hot to wear too many clothes anyway. Unfortunately, the bikini top while a good find, was also a size too small, so while it covered her nipples, it was rather scandalously teeny.

Thankfully it was just her and Ethan on the island. She'd worn scant swimwear on the poolside in front of him in the past. But had there been any other men in the area aside from her son and she'd have died of shame by now.

However: being alone on an island, in heat and the only attractive male for miles in any direction being the handsome nineteen-year-old boy that also happened to be her son? Rebecca wondered what sins she'd committed to end up in this circle of hell.

She'd tried to remedy her heat in a conventional way in the past, but raising Ethan on her own never left much time for dating. And while she was by no means unattractive, Rebecca always found it difficult to find a man. Not for lack of men in the age range of nineteen all the way up into their late forties throwing themselves at her when they caught even the slightest whiff of her heat. It was like post-marriage PTSD making her balk at any advances made in her direction.

Her husband, Ethan's father, had left them for his corporate lawyer. And not only had she stolen away Rebecca's husband, the bitch had even made sure Rebecca was left with nothing but a little state support. Her husband... ex-husband didn't even glance back at his college sweetheart, nor his own son in pity.

Ethan had grown up thinking of the man as a scumbag, which probably wasn't healthy despite being accurate. Then again, neither was growing up without a father. But somehow Ethan turned out alright. The story of his father leaving served as something of a cautionary tale, it seemed. And he did everything in his power to be the exact opposite; to be a good man no matter what.

Rebecca was immensely proud. So proud in fact, her hands strayed across her body just thinking of the way Ethan had grown up into a perfect young man. He always called home to check on her, made sure she was taking care of herself all the while taking good care of himself.

This one time while visiting home she's spotted him working out. Simple reps with dumbells, push ups, sit ups and the like, and he'd been wearing a tight t-shirt and a pair of tighter shorts. It was the first time Rebecca realised how much her son had grown up, especially by the outline of his sheath in his shorts.

She was a little ashamed to admit she'd married his father or his big cock, but knowing that length rather intimately she had to guess Ethan's was somehow bigger. Rebecca began salivating just thinking about it, closing her eyes and imagining that hefty chunk of rigid meat spearing her cunt and filling her depths like no man had before.

Rebecca tipped her head back and moaned as her walls parted to let the cock in, her moist tunnel rippling with excitement about the length. Her whole body flexed, begging to be fucked to the heights of orgasm.

And yet at the same time, Rebecca tore open her eyes, in a sense of sudden sobriety realising she was knuckle deep in her own snatch and filling the cave with the seductive musk of her heat while thinking about her own little boy - though _little_was a bit subjective here.

Still, Rebecca panted lividly. What the hell was she doing? This was wrong! Thinking of Ethan while touching herself? She should be ashamed of herself!

And yet the realisation didn't stop her. Shamelessly she lifted her skirt a little higher and propped herself up, fingers squelching back in and out of her sopping pussy. There was no tempering her voice, and with shuddering sighs of pleasure she began moaning, pleading under her breath for more. Her fingers felt inadequate even as she scratched that desperate itch burning between her legs. Her body wanted a cock in her.

Specifically, she wanted Ethan's. Her mind kept wandering to his aspect, imagining him planting his powerful arms beside her face as she gazed up at him, her body undulating back and forth as he thrust his hips, sliding his cock into the womb that had birthed him again and again. Before long she was even moaning his name.

"Ethan... Ethan, oh God that's so good." She wasn't even conscious of the quiet words leaving her lips. "Fuck me, Ethan. Fuck mommy until she cums!"

She threw her head back and slumped to the cavern floor. Two fingers slamming her yearning tunnel repeatedly, she circled her free digits over her burning clit. She could have thought of any other man ploughing her as she finger-fucked herself, but the delicious taboo of imagining her own son, her own flesh and blood dominating her under his weight, thrusting into her belly without reprieve or any sign of slowing was unlike anything Rebecca had felt before. She hadn't had to finger herself since she was a younger woman, and even then flicking through a magazine filled with barely clad muscular swimsuit models she'd never risen to the heights of orgasm this quickly.

So close to relief though, Rebecca suddenly stopped. The shuffling of feet on rock stopped her and she sat bolt upright, breathing deep and hoping she didn't smell her own sexual gratification simply because it was her own. There seemed to be no time to air out the cave either way. The moment she slid her fingers form her snatch and tugged her skirt back down over her hips her son clambered into the cave.

Ethan was every bit of handsome in real life as he was in Rebecca's fantasies. A five-foot-eleven lad, he clearly took good care of himself. Dressed in just a pair of shorts left his toned abs on display, as well as much of his clean white fur.

The resemblance to his mother was uncanny too. They definitely had the same eyes, and the same dark chestnut coloured hair. Though his features and build were more like that of his father. And while that did remind Rebecca of that disloyal asshole, it wasn't a bad thing either - Ethan was no doubt a wet dream of all the girls he'd gone to school with. And evidently, he was quickly racking up to be hers as well.

Rebecca swallowed hard, tugging at the hem of her skirt again, hoping the smell of her heat wasn't filling the cave. If Ethan noticed her pent-up scent of desperation, he clearly didn't show it.

"Hey," she greeted, trying to sound casual.

It worked well enough, and Ethan smiled. "Hey," he greeted back obliviously before holding up his satchel of fish. "I got dinner."

As the sun set, the rest of their evening played out rather uneventfully. Ethan didn't seem to be picking up her scent of desperation and didn't seem to notice the way her eyes kept drifting down his neck to check out the rest of his body. They chatted idly while scaling and gutting the day's catch, then roasted the fish on the campfire and wolfed down their substantial feed with a side of fresh water and coconut flesh. Rebecca was almost ready to admit she was getting sick of coconuts, but she'd stick it out for just a bit longer. What else was there?

After the usual small talk and cleaning up after themselves, the sun had gone down and they got ready for sleep. There was never anything to do during the dark of night, so they hit their cots early, so they could be up at first light and start the cycle of survival again. The schedule usually involved a few leftovers for breakfast, then Ethan hunting for supplies and food while Rebecca maintained the camp. She had admitted early on she wasn't really good at much else. Ethan took to the task of taking care of her without complaint though.

Little did Rebecca realise her son had a singular complaint.

Returning from stashing the fish guts somewhere outside, which would serve as lobster bait tomorrow, Ethan entered the cave to see his mother was on her hands and knees, patting down her bedding.

His eyes widened as they lingered on the taught skirt that rode up high over her hips. Her tail lifted the hem just a little more and Ethan was treated to just a fleeting glimpse of his mother's trimmed cleft. To his shock, he made a note of how the lips were swollen and parted even as Rebecca moved, a thin line of glistening pink flesh revealed within, wet with pent up desire.

Ethan suddenly picked up that scent he couldn't quite identify earlier. He'd thought it was something in the cave, or something blown in on the breeze from outside. Only now that he was actively thinking about it did he recognise the pheromone laden musk of a ravishing woman in heat. And it made his head spin with drunken lust.

His mother, crawling some ten feet away on hands and knees, was probably at the heights of desperation, ready to lift her skirt and let the next available cock ravage her pussy in every conceivable way...

Ethan stopped as he imagined he was attached to that cock and had to derail his train of thought as he began wondering how wet she was, or how tight the walls that birthed him still were.

He gritted his teeth and shook it off, but that didn't stop his member from sliding out of its sheath, bulging against the front of his shorts. And in masterful bad timing, as Ethan was desperately trying to pluck at the garment and shift the fabric in a way that lessened the obviousness of the bulge, Rebecca sat back, those perfect globes of her ass perched on her heels before she turned on the spot.

She was smiling, and Ethan couldn't help let his mind wander again, wanting to see that smile as he basted her face and tongue in a torrent of cum. He clenched as if about to cum, feeling a dribble of precum run from the tip of his cock and mingle into the fur on his inner thigh.

Rebecca seemed ready to say something, then stopped short when her eyes fell upon his groin. Her eyes visibly widened with surprise, and there was no point trying to be subtle anymore. Instead of sneaking about it, Ethan adjusted his pants in a bid to make the bulge less offensive.

The cat was very much out of the bad.

"Er..." Rebecca began to say when Ethan quickly turned away.

"Sorry. My mind's been wandering all day," he murmured. Not exactly a lie, though he failed to mention she was the one his mind had been wandering too.

"N-no need to be sorry," Rebecca stammered, recovering and sitting back in her cot. "Um... we've been stuck out here a long time. No prospects for, um... relief, right?"

Were he raised to be a barbarian Ethan would have disagreed while subtly tracing his eyes over her body. Was it just his horned-up paranoia, or was his mother now basking in his lusty gaze somehow? The way she sat back seemed to pronounce the slender length of her bare legs. She rolled onto her side and the way she faced him exaggerated her sexy curves. Ethan subconsciously licked his lips, the red blooded male in him wanting to lung forward, tear the shreds of clothing from the woman and plough her into the cavern floor.

He quickly cleared his throat and just answered with, "Yeah."

"It's been a while for both of us I guess." Rebecca pulled a few locks of her hair down over the side of her face, as if trying to hide as Ethan nodded. "Out here, no other men or women, no privacy..."

"Yeah."

His throat felt dry as he licked his lips. Rebecca was looking off to one side, at what Ethan couldn't see because he was entranced by her body. Long, slender legs with her skirt pulled taught over her perfect wide hips and inviting ass. Her waist tapered into a trim mid-riff, not a shred of fat to be seen anywhere until her wide bust, her perfectly round breasts plumped up just a little by the bikini top that was a size too small, but by no means an unwelcome sight.

He felt a little disgusted suddenly, realising he was ogling his own mother, and at the same time seeing her for the gorgeous woman strangers would see her as. This was what men saw when she took him out to get ice-cream as a child, or walked him to school, or chided him for throwing a tantrum when he didn't get the latest video game. They didn't see a caring mother, but instead saw a babe they wanted to bend over and slide their cock into.

Ethan gulped, realising he was thinking the same and jerked his eyes upward. He hoped the sight of her slender neck, her sharp canine features or dazzling blue eyes would do something for the strain in his shorts... no such luck.

He clenched and felt the rock-hard rod of flesh in his pants throb with aching desire. His balls churned and ached like someone was squeezing them as his body instinctively worked up a load it wanted to inject into Rebecca's tight womb.

When she finally looked back at him, it was Ethan's turn to look away, and he quickly retreated to his bed. "We should get some sleep," he mumbled, hoping the strained horniness wasn't evident in his tone.

"You're right," Rebecca quickly agreed, threw a little more driftwood on the fire and then crawled into the cot beside his.

They looked more like a pair of lovers irritated with each other, rather than a pair of horny and perfectly healthy anthro huskies laying half-dressed with barely a metre between them. Ethan faced one way, while Rebecca quickly rolled over to face the other way.

Darkness took the island quite quickly. But even as an hour ticked by and a few embers in the fire throwing only a very dim light about the cavern, Rebecca couldn't sleep.

She would close her eyes, and in a flutter of heat she'd feel her fingers trace down the bare parts of her body, pretending and yearning for the digits exploring every curve to be Ethan's. Her imagination ran rampant, so vivid was her fantasy she could feel his hot breath huffing down her neck, the massive hard bulge of his cock slipping between her ass cheeks and grinding against her most intimate parts as he huffed dominant words into her ear about being ready to fuck her like the slut she was.

She would press back, pleading him to do so under her breath, reaching down to wrap her fingers about his gorgeous stem... and she'd only grab air.

Rolling onto her back, she looked over to see Ethan was still facing away. She found herself entranced by the way the bands of muscle on his back flexed with every quiet breath. One hand was pawing at the bedding beneath her while Rebecca's other slender fingers played with the fur on her inner thigh.

She wondered if she could get away with it. Surely she could. It would be her little secret...

Rebecca was still plotting in her head as her skirt was pulled up over her hips again. Inch by inch she spread her legs wide and ran her digits over the swollen mons between her thighs. The flesh parted easily and Rebecca bit down on her lip hard so she wouldn't moan over the soft wet smack of her labia blossoming like a night flower.

Her index and ring fingers keeping her nether lips spread open, her middle finger curled to run up along the slick slit, teasing and testing the wet opening winking inside. Her free hand clawed at her bed hard enough to tear into some of the leaves and fibres. The ripping and fluttering was just an octave louder than her quickening breaths, and the slippery wet explorations of her finger across a throbbing pearl of flesh that screamed for attention.

As she let her eyes fall shut, she imagined the fingers belonged to Ethan. Once more she fell into the wildly taboo fantasy of her strong son leaning over her, his hefty cock resting on her stomach while his hands explored her aching body, finding her most treasured places and massaging her into a moaning, dribbling mess.

Her digits pressing firmly against her clit was too much. The slightest touch set her off, and rubbing in vigorous, fitful circles now, Rebecca couldn't stop herself from letting out a long, warm moan of pleasure. He gnashed her teeth to try and hold it in, but the husky failed and gasped loudly, again and again as if working up to a sneeze that would never come.

Instead, her lower body tensed. She'd been grinding and gyrating against her fingers, and now she slid deep into her crevasse, pumping the sopping tunnel with reckless abandon until her ass lifted off her cot. Her inner muscles rippled along her probing fingers as she rose higher and higher, building up to...

"Geeze, mom. Do you have to?"

Rebecca coiled in an instant, closing her legs around her hand and curling into a ball. Her eyes wide with panic, she quickly clapped her other hand over her muzzle then looked sideways at Ethan.

He'd half rolled on his back and was craning his neck to look back. But he didn't look irritated as his statement might have indicated. He just looked tired and... Rebecca recognised the look of male desperation from her promiscuous college years.

She pinned her ears flat against her head. "Oh... oh, God. I'm sorry, sweetie. I thought you'd fallen asleep."

When Ethan rolled over fully, she suddenly understood why he hadn't. That enormous throbbing bulge in the front of his shorts was clearly bothering him, and if it belonged to any other man Rebecca would have known exactly what to say or do.

Though, the truth of the matter was she did know what to say and do.

Gulping, Rebecca pulled at her hair a little. "I've, um... I've been having some trouble falling asleep."

Ethan grunted. "I noticed." He paused to take a deep breath, and seemed to relax a little. "I know, you're in heat."

He said it so normally, as if it was the most natural thing in the world. And biologically speaking, it actually was. It wouldn't have been the first time he smelled her, whether she was on meds or not. Since his terrifyingly hormonal teen years he would have recognised the scent of pure pent up desire to breed. Or more specifically, the desire to be bred. Rebecca wondered if he'd had any reciprocatively desire to slide his manhood into her fertile womb and unleash a volley of virile baby batter into her yearning...

Rebecca shook off the naughty thoughts of a lean young Ethan being tutored in may pleasures by an older woman like herself and blushed furiously. Fact of the matter was, he had smelled her. And despite embarrassment burning on her cheeks, she wondered with a lewd sense of hope that was the reason he'd gotten an erection earlier.

Rebecca hummed, smiling. "It's um... it's been a while for me. and since I don't have any meds to suppress it I guess I'm going a little insane." She chuckled, despite the lack of a joke there.

They stared at each other for a protracted second, then looked away.

"I haven't actually been with anyone since your father left," Rebecca admitted a little more downtrodden.

"Is there a reason for that?" Ethan asked, wondering if there was something severely wrong. His mother was an attractive woman - it felt weird to admit but it was the truth. And once again, it felt weird to admit, but for her to have a total lack of male attention just seemed wrong.

Rebecca shrugged. "I just haven't found anyone yet. What about you?" She turned the question on him as easy as a hitman turned a gun on his target.

It took Ethan by surprise, and he clammed up for a moment. He cleared his throat and simply said, "It's been a while for me too, I guess."

Rebecca arched her eyebrows, waiting for more that didn't come. "C'mon, Ethan. I told you how long it's been, now you can tell me. it's okay, I'm your mother. Who am I to judge anyway?"

Ethan caved. He'd always told his mother everything. They only had each other after all. That was how he'd grown up and he always felt he could share everything with her.

"Maybe..." he started to say.

"Yes?" Rebecca encouraged.

"Maybe... a couple of months. I was with someone a few days before the crash."

Rebecca arched a slender eyebrow; her mind automatically racing to try and figure out who it could have been. They'd been travelling together and hadn't been separated long enough periods of time until... wait, that was it!

Rebecca remembered with a secretive little grin. She was jealous sure, but also a little turned on as she thought to the hotel bar where an older woman, a tall and slender anthro giraffe about Rebecca's age had started flirting with Ethan. She'd though nothing of it and shrugged the whole event off as a flattering joke at Ethan's expense. Having been a little tipsy after one too many cocktails, Rebecca had retired early that night. She hadn't seen Ethan until that morning, so putting one and one together now she figured he had shown that lady a good night. He had been a little out of breath that morning now that she thought about it, and if there was one thing Rebecca knew about her fellow women was the more mature ones tended to be a little more energetic in bed than young girls now and days. Ethan must have been put through his paces.

She could see it vividly in her minds eye; the mature giraffe towering over him, squatting on his cock with the vigour of an athletic woman half her age. She would have no doubt been vocal in her approval too. A cock even half his size would turn any woman into a screamer. Rebecca hadn't known any woman to refrain from moaning like a top dollar whore when they were stuffed by a twelve-inch rod of fuck meat and squirting hard.

She wanted to call her son out for fucking an older woman, call him a scandalous young man who should be ashamed of himself for bedding a woman his mother's age - in the sauciest way imaginable of course. She decided to save him the embarrassment though.

"That wasn't too long ago," Rebecca commented instead, putting on a teasing tone. "You need a lot of attention then?"

Ethan rolled his eyes, and she chuckled apologetically.

"It's okay, sweetie. I've known men to be worse off after shorter dry spells."

Ethan wondered what the hell that meant, and accidentally imagined his own mother shushing a flustered man before sinking to her knees and wrapping her lips about his cock for a quick stress relief blowjob. He gulped, purging the thought as his cock pulsed, begging to be in exactly such a situation. Either wrapped in her mouth, her hand, her marvellous tits or her heat addled pussy, Ethan was sure he'd blow his load at the slightest bit of her sensual affection at this point.

"Haven't you tried... you know. Relieving yourself?" Rebecca pressed.

Ethan cleared his throat. "Well... um... once or twice, but... I dunno. I couldn't really finish."

That took Rebecca by surprise. "Why not?"

He blushed. "Just... I dunno. A bit busy with everything." He waved across the cavern as if to indicate the island. "Stress maybe?"

Rebecca sighed. "You shouldn't stress. It's true, thanks to you we've managed to survive out here comfortably this long. But if you get so pent up you can't take it... you're better off clear headed for whatever challenges await us tomorrow."

There was an awkward silence between them as Rebecca considered how she was going to say this with some sense of tact. But as it turned out, there was no way of doing that so she decided to just go all in.

With a sigh she sat up a little straighter and set her jaw. "I can help."

The way she blurted that out made Ethan's eyes widen severely. "W-wait... help?"

He seemed to shy away for a moment until Rebecca explained. "I don't mean help you with... y'know," she nodded at the bulge in his shorts. "Not directly anyway. I can... here."

She figured it was best to show him. So, reaching back she undid the knot holding up her bikini top and pulled it loose. The garment fluttered off into some forgotten corner of the cavern, and Rebecca sat on one hip, her slender legs curled to one side while proudly bare-chested in front of her son.

Her breasts were even more amazing uncovered, despite the tightness of the top having plumped them up. They hung more naturally, more appealing to the conservative male senses. Slightly lower than before, but not sagging. Slightly parted to give a nicer, sleeker valley between the perky furry globes. Each was a little more than a handful, straining the limits of a C-cup but not quite making a D.

Ethan barely even made note of her perky dark nipples and he was already drooling. Every ounce of him wanted to rush forward and grab his mother. Force her on her back, squeeze those amazing tits together and slide his cock into the tight furry valley between. He wanted to cum her a lovely pearl necklace around that slender neck, decorate her face with his seed and not just feed her the fruits of the sea, but feed her a tangy, salty treat straight from the tap.

He obviously held himself in check. And she seemed to notice the way he froze.

"It's okay, Ethan," Rebecca said soothingly in a way only a mother could soothe her son. "It's just us here. You can look at me while you masturbate. Maybe it will help."

Ethan had never been so torn in his life. He knew this was wrong, even just looking at his mother while jerking off like she was suggesting. But at the same time he was so pent up and desperate.

And his cock was harder than it had ever been! The thought of jacking off to his mom's tits was such a turn on! What was wrong with him? It was just a depraved thing, obviously. And still he was almost too excited to get started. He lowered his gaze from her eyes and gave her bare chest one more longing look. The bulge in his shorts shifted noticeably, growing significantly as he could hold no more of his erection it's sheath anymore. The cloth was being stretched to painful limits and Ethan would have to unzip shortly or risk hurting himself.

His Adam's Apple bobbed before his head did the same in a nodding motion.

Slowly, seeming a little embarrassed to do so, Ethan rolled onto his back and opened his shorts, finally freeing his immense red rod from its cloth prison. Rebecca felt her eyes widen again and stifled a gasp of surprise and lust as the mighty cock bobbed freely. Almost fourteen inches long, and about four in diameter with a large bulb beginning to swell at it's base, Rebecca had rightly assumed he was bigger than his father. Even his balls, large swollen eggs full of sticky cum yearning to be ejected across or in the nearest woman - whom Rebecca was beginning to hope would be her - were bigger than any set Rebecca had seen before.

There was a free flow of precum beading at the tip before dribbling down over the shaft where Ethan tenderly rubbed it into the bright red flesh like a lotion. Already, with just a few strokes he was breathing hard, but Rebecca was conscious of the way he angled his gaze away from her. It became almost counter intuitive to the exercise. He was spending all his energy avoiding looking at her, and as a result he was taking longer than this was supposed to.

Rebecca knit her eyebrows with an affectionate expression. Her poor boy was so pent up and embarrassed at the same time. And that would not do.

Moving closer, Rebecca tenderly put her hand on his arm, the same that was stroking his member with feverish lengths now. He suddenly stopped and whipped his eyes about. But instead of looking at her bare breasts, one cupped with the nipple tweaked between two fingers as Rebecca wanted to put on something of a sexy show to help him along, Ethan was drawn up to lock her gaze.

They stared into each other's eyes for a moment, pondering the exact same shade of ocean lagoon blue, the similar muzzle structure, the same hair and fur colour...

Rebecca's yoni screamed for attention. Again her hand absently drifted from her nipple, floated past her belly button and found it's way between her thighs. She expected Ethan's eyes to follow, but as he lay there panting and staring, his eyes remained on hers while her fingers tested the waters. She was sopping wet. Wetter than she had been for his father on their wedding night. Wetter than she had been for any man in her life. The heat threatened to ignite the fur on her finger as she dipped into her tunnel, which clenched about the digit. Her walls were desperate with desire.

Rebecca whimpered as a profoundly simple thought crossed her mind. 'Fuck it!'

Rolling onto her knees, she boldly pulled Ethan's hand away from his member and wrapped her long slender fingers around the shaft herself, the moisture from her pussy mingling with the clammy, slippery salve of precum that was now pooling at his balls.

She took over without thinking, a small smile growing into a full lusty grin as Rebecca's hand jerked up and down her son's cock. She worked the rigid meat with uncanny ease, her tits bouncing with every stroke, catching Ethan's mesmerised gaze. Every sense of taboo burned out faster than a scrap of confetti on an open flame.

Ethan flattened his back on the floor and bared his teeth with a distinct, sucking hiss. Rebecca felt her boy tense. Biting her lip, she figured something was probably wrong. Other men would have finished already at this pace. So something was probably missing.

"God, it's so big," Rebecca said with a gorgeously womanly smile. "It barely fits in my hand."

"Geeze, mom. Really?" Ethan jerked his eyes away, blushing furiously.

"It's nothing to be ashamed of," Rebecca cooed. Then biting her lip, she added a little more coyly than she intended, "I think this is going to take a little more than just my hand to take care of."

Ethan hardly reacted to what she said, more so tensing as she tightened her grip for a moment then leaned forward. The wash of her hot breath over his crown was amazing and he curled his spine a little, subconsciously aware of what was happening and willing to thrust forward to make it happen faster.

There was more than enough precum glazing his cock, letting Rebecca's palm glide up and down the shaft with lewd, squelchy noises. The strong musk coming from her son's member was overwhelming her with the desire for a taste, and she gave a brief lick across the crown.

Ethan tensed when her tongue lashed over his tip, then instead of the slick up and down motions of her palm stroking his shaft he felt her broad tongue press against the base, then ride up along the underside, lapping up the slippery, salty layer of precum as she went.

Rebecca's eyes rolled into the back of her head, and she felt the fire in her cunny re-ignite with a fresh intensity. There was no holding her back anymore and with a hungry growl she opened her mouth wide and slipped the entirely of his cock into her muzzle. There was zero trepidation as she bobbed her head down and down, letting the tip probe her throat, drawing soft little gags from the woman as she suckled sweetly over every inch she could fit.

Ethan had never met a woman his own age who took him in her mouth so quickly. All others would hesitate, or refuse in every way but verbally, simply licking him for a bit to skirt the issue and then suggest they move on. His own mother sucked him right down to the swelling knot, his shaft bulging in her throat as she gargled a little with every inch she swallowed down.

He clenched, lifting off his bedding just a little and dug his fingers into the cave floor. He'd never felt anything close to this before. The way her tongue lashed over his most sensitive parts, her throat muscles constricting about his cock to massage every inch while her lips puckered over his knot... Ethan liked to think he had good sexual stamina, but his mother fucked him with her throat for less than a minute before he felt his balls tighten and a rush of cum bubbling at the base of his member.

"Oh, God... wait, mom I'm going to..." Ethan's face screwed up with effort as he tried to hold back as long as possible. Those would normally be the cue for his lover to immediately take her mouth off his genitals and start stroking his length.

But not his mother. Rebecca greedily inhaled another inch of his cock, gagging for a brief second and bobbed her lips across his member with renewed enthusiasm. Her tongue rolled across the sensitive flesh of his crown, gloriously hot and slippery, massaging the glans...

Ethan made the mistake of looking down. Rebecca's eyes looked up and locked into his gaze, searching for approval as her lips worked up and down the shaft of his member. He clenched one more time and failed to hold back. A few small spurts of errant cum basted his mom's mouth, causing her to freeze, but the corners of her lips to curl upward.

Her tongue lashing across the sensitive flesh, her look of unabashed lust, eagerness to drink down every drop of his essence right from the source all proved too much. He clenched one more time, then let his mother have exactly what she craved.

He erupted in her maw, glazing the roof of her mouth. She swallowed it down with long throaty gulps though, moaning as she felt the slimy thick goo warm her gullet all the way down to her belly. Still suckling, she swallowed down the rest Ethan gave her as well. Rope after rope after rope - it just seemed to go on forever. Rebecca opened her eyes with surprise, losing track of how many mouthfuls she was swallowing down. After a while she felt the strain on her stomach like she'd downed a litre of water all at once.

Clutching her belly she coughed as more cum jetted into her mouth, her son still spasming between her mouth. Long pearls dribbled down his shaft where they escaped her muzzle. She had no choice but to pull back, and as she did there was still more Ethan had to give her. There was no more question of want, he simply had no choice. His balls tightened and his member throbbed between her slender fingers. Long streams of the thick, slimy batter, it's musk assaulting Rebecca's senses and making her head spin, painted the side of her face. Spurts blasted her in the throat and as she pulled further away with surprise, three more weaker spurts, the last ones in this copious torrent landed across her bare breasts. It was so hot, she could feel it burning through her fur and sear on her bare nipples.

She gasped for air looking down at the mess Ethan had made. She was literally drenched from her cheek down to her breasts in his cum, some of it flecked on her lips where she licked it up eagerly.

"Oh, God," she whispered, eyes wide. "That was so much. I've never... ohhh~!" Her head span again. His salty taste on her tongue, the strong scent of his masculine seed marking her as his property - it made Rebecca burn with fresh desire.

Not that a simple blowjob would have satisfied her anyway. She needed more. She wanted that big cock inside her. At least, it would have been nice to feel the big thing stretch her open and plunder her sacred trove.

Rebecca sulked a little, hand idling across the shaft of the wet member. With such a massive eruption, surely Ethan had nothing left for tonight. She figured she could tug him all night and not get any more life out of this delicious stem.

Disappointment quickly turned to amazement though. She squeezed, and Ethan's cock throbbed firmly in response. He was still hard as an iron rod, just like when they had started. Rebecca was shocked as she was excited, letting a sloppy smile cross her muzzle. Every other man she'd ever bedded would typically cum and then roll over for the night.

Not Ethan it seemed. She dipped down and ran the bridge of her muzzle up the underside of the cock, breathing in the delicious scent and feeling a fresh torrent of excitement run down her thigh in response.

"Still so hard," she whispered huskily. "You clearly still have more for me. That's good."

Whipping around on the spot, Rebecca eased forward on hands and knees before lowering her chest to the ground. Her ass pointed up into the air with her skirt hiked up over her hips, Rebecca presented everything to Ethan.

"Mommy's so excited. It's probably going to be hours before I can get to sleep." She wagged her hips, looking at him pleadingly over her shoulder. "Are you going to fuck me in the meantime?"

Seemed like a dumb question really. Ethan scrambled to his knees and sidled up behind her without even thinking about it.

The only sound he made was the only reply he could think of. "Like you're the last woman on earth."

Rebecca giggled excitedly, yelping slightly as she felt his powerful hands grasp at the curves of her hips and draw her in close. The hot rod of meat slapped across the crevasse of her ass as he humped back and forth for a moment, grinding that mighty stem across her fur and the base of her tail.

She whimpered impatiently. "Don't tease. Just give it all to me. Fuck my pussy silly. Mommy's so horny, she needs it so baaaa-aaaaaaah~!"

Rebecca hardly finished her sentence as Ethan rocked back, lined up and pressed the crown of his red rocket into her sweet, hot folds. The soft lips of her pussy spread to let him in, her tunnel slipping around his girth with remarkable ease. Her excitement flowed so freely and the precum was practically pouring from Ethan's tip, in one wet motion he was able to slide into her until a tight mouth of resistance permitted him no further, leaving maybe a little under an inch of clearance between her clenching opening and the bulb growing at the base of his cock.

Ethan wouldn't have known it - how could he have possibly known before now - but it seemed his mother was a screamer. She was so lost in the throes of heat that all it took was one entering stroke to tip her in to the heights of orgasm; and when she came she came loudly.

Rebecca howled with delight, her eyes rolling into the back of her head as she planted her chin flush on the deck. She undulated back and forth, voice trembling in time with Ethan's earnest thrusts as he dug his fingers into her wide ass, holding on for dear life while driving forth into her too long neglected depths. Rebecca's own arms lay weak and useless on the cave floor by her sides, her fingers twitching the same as her hips as she came torrent after hot torrent of creamy sexual gratification washed Ethan's swinging balls in warmth.

She'd never felt like such a complete woman in her life. Not until her own son's big cock was crammed so deeply inside her.

Tight as a virginal canal wrapped about his member and hot as a furnace, Rebecca's pussy quivered with unbridled passion. The combined heat from Ethan's cock and the jets of her liquid approval was enough to set off her clit without the slightest hint of friction. The lower half of her body bucked back and forth uncontrollably, and she drooled out the corner of her mouth, literally yelling the most depraved curses and slutty demands for more that Ethan had never thought his mother capable of. The sight and sound of her going to absolute town, bucking and rocking back and forth when Ethan failed to move was almost enough to set him off.

"Oh fuck! Fuck, Ethan, keep fucking me like that! Make mommy your dirty little cum-dumpster. I want it all! Pump me full while I squirt all over your cock like a worthless little slut!"

Ethan honestly had to double-take. He had been with some slutty girls in the past, but this... it was something else entirely. His mother was suddenly possessed and while it was an immense turn on it was at the same time just a little off-putting. This was the woman who'd cuffed him when he said 'crap' at the dinner table.

Rebecca in the meantime gushed again and again over the course of several minutes before Ethan could take no more. Before long he felt a tightness at the base of his cock, his knot beginning to swell where it hung unloved just outside Rebecca's body. The feeling of about an inch of cock hanging in the wind wasn't entirely unsatisfying though. He'd fucked shallower pussies before, and in most recent memory this was probably the deepest he ever managed to get his disproportionate length into a woman's body. He'd never tried anal, all his partners balked at the prospect when seeing him fully erect. But considering how unabashed his own mother had been so far, he had some hope that some experimentation might be on the table. The night was young after all.

As his seed bubbled up through his shaft with a divine rush of pleasure that had his body aching greedily for more, Ethan while mindless in the throes of joy was still conscious of cumming inside his own mother. So, in a moment of lucidity, clenching just before release, he pulled back and slid his member from her, then up between the divinely soft cheeks of her ass. He erupted a moment later, ejaculating into the fluff of her tail and all across her back.

It was as hot as Rebecca's core, the long ropes of cum thick as icing laying in long streams from the small of her back up to between her shoulder blades. A few more powerful torrents reached Rebecca's hair, but having orgasmed with literally every one of Ethan's thrusts, she was far beyond the realms of caring. All that mattered was the satisfying ache of her pussy being thoroughly plundered, a lingering itch for much more and a deeply fulfilling slimy warmth up across her back. There was so much cum, almost as much as Rebecca had failed to swallow in its entirety before painting her fur, leaking down her sides, dribbling from her hard, sensitive nipples and pooling beneath her.

Their cots were already a slippery mess, but neither husky cared much.

Another pang of disappointment curdled in Rebecca's gut as she felt the last spurt of his seed dribble between her ass crack. Surely that would be all Ethan had left. Now he had to go soft, and Rebecca felt her body was only just starting to get warmed up.

Swivelling about on her hands and knees she figured she could try licking him back to readiness. But as she turned about, she realised there was no need.

Ethan was still hard and alert. His massive slab of meat twitched with excitement under her gaze, which drank in the magnificent sight with the lustiest version of motherly pride imaginable... in fact, such a look had been unimaginable - and unwelcome - to Ethan before tonight. However, trapped in the throes of passion and eager to feel more of the pleasures of his mother's gorgeous body had to offer, Ethan was excited to slip into her again.

Licking her lips with a saucy twinkle in her eyes, Rebecca lunged forward and opened wide, swabbing her throat with Ethan's length with one greedy gulp. Ethan grunted, cupping her face in his hand as he thrust forward, feeling her throat bulge under his fingers as he fucked her face for a few earnest thrusts. Her throat was so hot and tight, he would have been perfectly content to just keep fucking her like this until he came down her gullet. But Rebecca wanted him elsewhere it seemed.

Pulling back she immediately laid flat on her cot, bits of bedding sticking to the cum glazed fur on her back. Her arms were open, as were her legs, presenting for a perverted version of an intimate mother-son hug.

Ethan fell into it immediately, and as he did, his lips locked furiously against hers. That took Rebecca by surprise, and her eyes widened, but only for a moment. Breathing his warm musk deeply through her nose, her eyes fell slowly shut and she hummed with bliss as their tongues intertwined in a passionate embrace.

His hips rolled forward at the same time and probed her pussy, drawing a muffled squeal of excitement from his mother as her folds parted to let him in. Rebecca quickly locked her ankles around his back and moaned loudly into the kiss.

Again, he bumped her cervix, itching the depths no other cock had ever touched. It was magnificent and she couldn't help but let her voice flow, her cries pealing from the cavern walls and replacing the lonely, quiet island nights normally filled with animal calls or gentle waves on the shore.

Rebecca raced to the heights of orgasm in just a few of Ethan's powerful thrusts kissing her core. Lunging forward she bit into his ear, her moans shuddering along with her body as if she'd taken a sudden fever. Again, and again he assaulted that tight barrier, goaded by Rebecca's pleas for more.

But eventually Ethan grew too zealous. He was maybe his second dozen bouts in when he pushed and felt something pop. A tight, wet fleshy mouth enveloped his crown with pursed lips and Ethan bit his lip so not to cum right away. Rebecca on the other hand yelped in sudden distress as the last inch of cock sank into her yoni, penetrating her cervix.

Reactively Ethan pulled back. "I'm sorry..." He began to stammer, but Rebecca silenced him with a kiss and her nails in his back.

"Keep going," she hissed, pulling her lips back just a little so she could speak. "Punish me. I've been such a bad girl, fucking my own little boy. Mommy needs to be disciplined."

Sliding one hand down to his rear she pulled him in to thrust inside again. Once more he bumped the tight mouth at her core, then with a moment of persistent pushing, in he popped. Rebecca threw her head back, and Ethan had to quickly catch her with his free hand, the other groping her ass tightly, so she wouldn't knock herself out on the cave floor.

Rebecca's screams amplified, though Ethan's feelings were a little mixed. There was a fiery blaze of pain welling in her eyes, but at the same time her screams were pleasured, even more so than before. Though before Ethan could consider slowing, Rebecca shook with familiarity. Her tunnel sucked him all the way in, the rippling muscles milking him as she squirted out a torrent of hot femcum with a sense of finality.

Her expression was a little frightening at first. There was a vacancy in her stare as she rolled her eyes, locked in a seizure like fit of absolute rapture. Her squirts came in long flows for a while, drenching Ethan's crotch and the young man had to tighten his grip so she really didn't knock herself out on the hard floor this time.

It was so hot and tight, Ethan couldn't hold himself back anymore. And considering where he was firmly lodged, deep in her womb, he wanted to pull back. Only Rebecca held her son in firmly, and there was no time to wrestle free.

Slamming into her depth one last time, Ethan injected his last, copious thick load right into his mother's womb. Torrent after torrent, a bigger wave than before - if it had been at all possible - of thick salty honey irrigated Rebecca's innards. Her belly felt swollen, and she was reminded of being nine months pregnant. She was heavy, drowsy, and above all, immensely satisfied with the load deep inside her, and a knot swelling just inside her opening, holding Ethan firmly in place. Not that her arms and legs slackened after the mind shattering orgasm that just ravaged every inch of her body. She tingled from the inside out, still shaking and twitching, her vice like pussy still clenching to milk out the last dregs of her son's cum.

Ethan seemed content to stay that way, connected to her while nestled deep in the quivering canal that had birthed him nineteen years ago.

That suited Rebecca just fine, and she yanked him closer by his head, kissing her son deeply one more time.

That wonderfully taboo sexual encounter would not be their last. Every morning and evening, and sometimes in-between if there was time, Ethan and Rebecca would fuck frantically. Days passed and the number of pleasures they shared became innumerable. Ethan would sometimes wonder who this insatiable woman he had known all his life truly was. She was as unabashedly slutty as she was gorgeous, taking his cock in every orifice and every conceivable position they could come up with for as long as it took, never once losing her grace or even an ounce of energy. She could be face down, ass up, blubbering and moaning out the foulest of curse words as her body shook with orgasm after orgasm, squirting non-stop the whole time; and still she looked as beautiful as she did when lounging on the beach like an Instagram model.

One minute she was his desperate little cum-dumpster begging for his cock to fill every hole... the next she was his kind and supportive mother again.

Then one day it seemed their pleasurable time together would come to an end. Finally, a passing ship spotted their smoke signals and sent rescue. Rescue teams had picked up other survivors from the ocean shortly after the plane crash, and had been searching the area, but it seemed the mother and son had drifted way outside the search area.

Regardless, they were brought back home. Back to civilised life.

Ethan got back into the groove of the college life fairly quickly. About a month in he was well on his way to becoming a productive member of society. Getting home, he locked the modest apartment's door behind him and called out to let his mom know he was home.

And like the groove of college life his mother stepped out of the kitchen to present herself exactly as predicted. Not to announce dinner was on the table, but that in fact 'dessert' was ready to be served.

Rebecca slid around the door post and immediately fell into a sexy pose, half leaned against the wall and with her free hand resting on her hip to draw attention to her delicious curves. Tonight's outfit indicated she'd gone on something of a cleaning spree. Inch heel shoes with silver buckles on her feet, she had opaque black tights hugging her long legs up to the white ruffled hold-ups on her mid-thigh.

The skirt of her black apron could barely be called that considering it hid nothing of her quim that glistened with pent up excitement. Long velvet gloves and a white hairband completed the sexy maid outfit, complete with suggestive smirk and a slutty twinkle in Rebecca's eye.

Ethan felt his cock go rigid in an instant, his jeans completely failing to hide the hefty bulge.

"Welcome home, son. Dinner is still in the oven. Are you going to fuck me in the meantime?" she asked coyly, biting her lip.

Ethan smiled as he thought to himself: Like you're the last woman on Earth.
