Katie shifted in her chair, leaning over the laptop and letting out a quiet sigh. She was making an effort to focus on the lecture on her screen, delivered in a sleep-inducing voice by a balding professor. She managed to take a lot of useful notes, so it wasn't entirely futile, but there was no hiding it that her mind was mostly elsewhere.
"Fuck," she cursed, groaning in frustration. "I can't stop thinking about... oh!... about him, and about... oooh!..."
A long moan escaped her lips, which her breathy words folded into, as the shapely blonde added another finger to the soppy handiwork between her legs. She spread her tanned thighs a bit more, to give herself better access. She felt a pleasant shiver when the chilly air touched several new, freshly exposed spots inside and outside her sizzling hot pussy.
It aroused her nipples, too; not that they required much. The wanton girl allowed her other hand travel to one of the engorged nubs, squeezing it gently to elicit one more, lusty moan. She continued churning the gooey mess in her soaking wet hole, all the while trying to concentrate on the droning voice in her noise-canceling earbuds.
"O-okay, that's... a bit better," she breathed, now pinching the other hard nipple. "Maybe I just need... to touch myself... more..."
It wouldn't be too difficult -- indeed, Katie was able to touch every intimate spot on her nubile body. She was completely naked right now, which was in fact the normal state for the beautiful, nineteen-year-old girl. Neither she nor her family ever wore clothes anymore, save for her mom's occasional trips to the grocery store. Especially Katie and her brother Ethan, who became permanent nudists in order to aid the sexual education of the inexperienced, eighteen-year-old boy.
Or rather, the *formerly* inexperienced boy. Thanks to his older sister, Ethan had been quickly catching up on the matter, and in a very practical way. The siblings started having sex at the break of summer; since then, they would hardly ever stop. They walked around the house naked and fucked wherever the urge struck them, often within earshot or in the full view of their mother. And their mom actually *agreed* to this, tolerating and even condoning her kids having sex so openly, because it was their journey of sexual discovery which she wanted to be fully supportive of.
Needless to say, it had been a very memorable summer. But after living in such a blissful sexual nirvana, the return to her usual college classes, even if she was now taking them remotely, was a tough ordeal for Katie. Her completely out-of-control libido, developed over the months of fucking her increasingly sexually adept brother, had a really hard time coping with even just a couple of hours of academically motivated abstinence.
"Finally!" she let out, as the professor's monotonous voice announced the end of the lecture. "Last one for the day, and of course it had to be the most boring one!"
Sighing, she took the pruned hand out of her needy pussy and wiped the dredged-up juices over her flat, lightly muscled stomach. She closed the laptop and removed the earbuds, then lifted her bubbly butt and grabbed the wet towel she'd been sitting on. It was thoroughly soaked, mostly with her vaginal secretions, so she made a face and threw it straight in the hamper. For a moment she thought she'd heard a sound outside, but after several hours of listening to voices in her ears Katie wasn't sure if that was real or not.
Once she opened the door to the hallway, though, she realized that the sound *was* real, and it was exactly what she'd thought it was. Now that she was hearing the full, orchestral version, it was extremely evident why Katie's earbuds had to be noise-canceling.
"Ooooh! Ooooh! Oooh!... Oh my god... Ethan, son... Yes! Fuck me! Fuck your mother, Ethan! Fuck her slutty pussy with your huge, hard, incredible cock!"
Yup, that was Katie's mom and brother. Judging by the pitch, intensity, and direction, it sounded like they were fucking somewhere downstairs, likely in the living room, and that they'd been going at it for a while now. The cadence of Mom's whimpers indicated that Ethan was probably thrusting into her with deep, full-length strokes of his unbelievable 10" shaft. He was shoving it in quickly, his sister thought, but taking his sweet time on the way out to tease and rub against his mother's sleek vaginal glove.
Katie could read all this from her mom's ecstatic cries because this wasn't the first time by far that their mother was having sex with her kids. Living with the dynamite blonde daughter and her surprisingly capable brother -- both of whom had been doing nothing but fucking like bunnies, all over the house -- it took less than a week for their mom to discard all her inhibitions about incest. Then, after clearing up one little misunderstanding, their mother had finally joined the siblings in their sexual 'experiment', as she'd call it, and the three of them had been fucking ever since.
Yes, it had been a *very* memorable summer indeed.
Following the lurid noises, Katie descended the stairs and peeked into the living room. A raunchy smirk instantly crept upon her face, as she spied the ongoing debauchery that was taking place only a few feet ahead.
"Yeees, Ethan, fuck me! Yes, yes, don't stop... Don't stop, sweetie! Yes, I'm so close... I'm so... Oh my god, I'm gonna.... AAAAAAAAH!"
It was clear that Ethan had just brought his mom to another screaming orgasm. The delirious cry was wrought from her lungs by the savage thrusts of his massive cock, then prolonged into a wailing aria by those same ceaseless efforts of the strong, virile young man. The sight of their coupling was pornographically erotic; as she took it in fully, Katie couldn't help but gasp.
Their mother, Linda, was splayed obscenely on a large ottoman in the middle of the room. Head hanging beyond the edge, her large pendulous breasts swayed and flopped from the force of her son's strokes. She was getting absolutely railed by the fit teenage stud, who had put her meaty legs on his shoulders and was relentlessly thrusting his huge meatpole into the piping hot furnace between them. Thick thighs were bouncing him off, assisting his expert hip work, as he was fucking the curvaceous woman throughout her ongoing, thunderous climax.
"Shit," Katie cursed under her breath. "So, that's what I'm missing out on now..."
Linda's howls of pleasure went on for a good while. Sometimes, they'd take the form of some primal pseudo-words that she'd shriek out frantically atop one of the many crests of her body-shaking orgasm. Those crude, practically animalistic noises soon abated, however, as they were replaced by the regular chant of broken yelps and moans that punctuated their continuing mating.
But shortly after his mom calmed down, Ethan also slowed down and eventually came to a halt. He decided to change things up for the next bout of their lurid tryst.
"Flip over, Mom!" he growled. "I wanna pound that tight pussy of yours from behind!"
Helped massively in this task by her son, the half-delirious Linda assumed a stance on all fours, with the large ottoman supporting the weight of her tiring body. The fleshy hemispheres of her expansive ass were right in front of Ethan now, and so he plunged his juice-slicked shaft back into his mother's gaping wet hole.
Then, he simply started fucking her all over again.
"Okay, that's it," Katie decided, straightening up as she sauntered into the room with a sultry smile on her face. "Good afternoon, my dear brother. Having fun?"
"Hey, Katie," he greeted her with a grin, the pace of his thrusts unchanging. "You're all done? With your classes and stuff?"
She sighed, as she padded across the room. "Yes, for today," she said. "Bad news is, I'll have to do pretty much the same thing tomorrow."
A chuckle escaped her brother's throat, momentarily throwing him off-balance. He decided to slow down a little bit after that, but even then he was far from stopping his avaricious plunder of Mom's dripping wet snatch.
"I guess it is a bit funny," Katie said. She was staring at the lewd action, with both a frown and a lusty smile on her practically drooling mouth. "Funny for you, that is. You've got like what, half the number of classes that I do?"
"Ugh, yeah, something like that," Ethan admitted.
"So, you just wrapped it up, and then you ran to stick your hard cock inside Mom, huh?"
He gasped. "Sis, you're making me think you're jealous..."
"Of Mom? No," she denied immediately, smirk turning into a wider grin. "Of you *fucking* Mom? Instead of me? Right now?... Hell yes! Bro, I've been dreaming about your thick, hard, giant dick for hours!"
He let out another chuckle, as he looked at his sister's exposed and absolutely drenched pussy that was just about at his eye level. It distracted him, obviously, though it didn't disrupt his steady thrusts that rebounded, again and again, from Mom's bountiful asscheeks. So far, he'd been keeping a measured pace inside his mother's steamy orifice; but his sister's simple praise of his extraordinary manhood, and the sight of her practically squirming slit that yearned desperately for his cock, had him on the verge of cumming within seconds.
"I'd love to switch... and I think Mom... wouldn't mind," he said between breaths, glancing down at the mature woman. He was right. Other than letting out constant moans, she seemed thoroughly pacified by her son's cock and the many orgasms it had already given her this session. "But I'm, uh, getting kinda close here... so maybe..."
"Oh, that's fine," Katie said, as she approached the other end of their mother's shaking, undulating body. "I think I can get her to help me with this..."
Ethan raised an eyebrow in curiosity, watching his nubile sister kneel on the soft carpet. She then scooted forward and brought her needy snatch in the vicinity her mom's drooping head. She cradled Mom's head in her hands, lifting it gently to have her look at her daughter's kind, loving, albeit mischievously grinning face.
"Mom," Katie pleaded sweetly, "I *really* need you to lick my pussy. Can you do that?"
"Y-yes," was her mom's weak answer, but it was all that the horny girl needed. She scooted even closer, all but shoving her juice-leaking cunt in Mom's face, and winking at her brother who knelt on the other side of Mom's prone body.
Before long, the slapping and shlicking sounds of Ethan's vigorous rutting were joined by another source of lustful, feminine moans. This time, though, it was his nympho sister who was gasping and moaning in pleasure, struggling to keep her body upright while her mother attacked her overheated and under-stimulated pussy. That poor, neglected slit was receiving the thorough licking it deserved, getting the girl off several times in preparation of getting totally reamed by her brother's immense cock.
"Oooooh, yes, that's it, Mom!... Lick me... right there!... Oh fuck, fuck... Fuck, I'm coming, Mom! Oh my god... Oh my... OOOOOOOOH!"
She was struggling to stay on her knees, so her mom tried and helped. She swung her arms around her daughter's firm, perky butt, squeezing the taut globes and bringing Katie's crotch even closer to her mom's hungry mouth. The distance was further closed by Ethan, who kept thrusting into their mother with the same youthful vigor, literally fucking her face into his sister's throbbing snatch!
But it wasn't going to be for long. The boy's bloated nuts were arriving at their boiling point, as pressure rose greatly at the hilt of his straining cock. He didn't resist it. He'd been fucking Mom for about half an hour, taking her through a gauntlet of full-body orgasms, so the teenage stud more than deserved to unload the voluminous content of his massive testicles.
"Ugh, fuck," he let out, "this is it! I'M COMING, MOM!"
He yanked his exploding cannon out of his mother's thoroughly plowed pussy and aimed it at her luscious body. Jet after jet of his virile cream coated the large, fleshy pillows of her breasts, before more of the potent boy's cum landed on her soft stomach and stuck to the wisps of her pubic hair.
"Oooh, yes, son!" his mother croaked, struggling to stay conscious as her arms fell from her daughter's shapely ass. "Cover me... in your cum! Ahh..."
Grunting and groaning in pleasure, Ethan did just that. He then directed the last few spurts straight ahead, where his sister was shuddering from the aftershocks of her numerous oral climaxes. The force of his final volleys was still strong enough to hit her, landing on her round breasts and the flat tummy. The rest ended up on Mom's neck and chin, which her playful and slutty daughter immediately scooped up and shoved into her hungry mouth.
"Oooh, thanks, bro!" Katie purred. "Is this an appetizer?"
"Yeah," he panted, grinning at the sultry blonde. "And you got more on your tits, too!"
"Mmm, I'm gonna keep it there for now," she said, savoring the taste of her brother's thick cum. "There's gonna be more there soon, because obviously you're going to fuck me and *glaze me* next, right?"
Katie put her hands on her hips, indicating she absolutely wouldn't accept no for an answer. In her opinion, that was only fair. Mom already had a few hours of sexy fun time with Ethan, so Katie obviously had to be next. Her studly brother was simply going to have to cope with the demand, bringing his huge dick to bear where it mattered and where it was truly needed.
...Not that he'd ever lodge any complaints about this, of course. Fucking his insatiable sister, or fucking his nympho mother -- or indeed, fucking them both together -- were precisely the kind of activities that Ethan was *very* well versed in.
"Sure thing, sis," he said, grinning, as he gripped his barely softened cock. "Lay down and spread your legs, uh, *somewhere*, and you'll get every inch of my dick, you slut!"
After all, this whole summer he'd been doing little else.
***
"So, uh, I think you've been talking about it earlier but I was... well, a little *preoccupied*," said Linda, sheepishly, talking to her children who sat across the dinner table. "I wanted to ask: how was your first day back in school? After such a long time, it must've been quite an adjustment..."
The siblings were in their usual position, with Katie grinding on her brother's lap. She had his hard cock buried in her softly quivering pussy, feeling its rigid tumescence as it pried apart her glistening lips. There was a look of serene contentment on her face, which unfortunately didn't exactly match what the naked girl had to say.
"It's... oh!... it's been really difficult, Mom," she replied, letting out a gasp as Ethan slowly thrust into her. "I think we are just so used to fucking all the time, it feels weird that we are now... ah!... that we're not supposed to do that anymore. It's a pretty big change..."
Her mom nodded. "I know, sweetie. You and Ethan were practically inseparable, and now you have to stay apart for several hours each day. It must be very tough on you, which is why I've been wondering... Have you considered that you could maybe go through both of your schedules, in detail, to try and find some small gaps where you could sneak in at least a short quickie?"
With her ample boobs shamelessly groped by her younger brother, Katie let out a protracted moan. "Ooooh!... I don't know, Mom," she panted." We, uh, we don't really do 'short', like, at all. Ever since Ethan and I started fucking, it's always been hours and hours of sex, every time... Once we get going, it's pretty much impossible for us to stop, so most of the time we'd just try to tone it down a little, like... ooh!... like now..."
A soft sigh escaped Linda's lips, for she was well aware of her kids' insatiable appetites. Her own rampant libido wasn't all that far behind either -- she was simply more used to controlling it. It was Linda who had maintained a semblance of sanity during their wild summer of unrestrained love, after Katie and Ethan had instigated and then fully succumbed to an all-consuming, lustful madness.
Because, let's be clear: madness was the only accurate way to describe it.
For many long weeks of summer -- indeed, until as recently as *yesterday* -- the siblings had sex practically around the clock. There had been many periods, of several days or more, when they seemed to do little more than eat, sleep, and fuck. The only thing that somewhat moderated this carnal frenzy, other than mere hunger or thirst, was the fact that Ethan liked to work out in the home gym. This one short hour was about the longest break that the sex-crazed couple could stand, for otherwise they had been rutting more or less constantly.
"Right, I suppose I should've known, huh?" their mother said, teasingly. "Whenever I see my kids fucking at the dinner table, I should appreciate how much they are *toning it down* for me..."
Both of them snorted a laugh. "Yes, precisely!" the girl said with a cheeky grin. "I mean, it would be really hard to keep a fork steady if Ethan was actually railing my pussy right now, so it's not like we are doing it just to be polite." Her brother chuckled. "But anyway, more seriously -- it wouldn't work for us, Mom, to have those short fucks during the day. We can barely let go of each other already, so having to split not once but multiple times a day would be, ugh..."
"Difficult," Linda finished for her, and sighed. "Yes, I get it. It would be silly to expect that we'd get back to -- well, definitely not *normal*, but somewhat more manageable -- overnight, but I don't think we have much choice... Unless, of course, you have some other ideas how to make this transition a little easier?"
The siblings looked at each other, eyes clouded with a fog of ambient lust. Their nonverbal communication, honed over days and weeks of nearly constant sex, was close to perfect now. They could understand each other practically without words, especially when Ethan's huge cock was sheathed inside Katie's tight pussy,
Unfortunately, all they got from this melding of minds was that no obvious answer had come to either of them.
"Maybe we should first, uh, try to figure out what it is that we want?" Ethan then suggested, as his first contribution to the whole conversation. "We might have a better idea what to do then..."
"Oh, that's easy," Katie said, looking straight at their sexy mother. "I want to fuck you, Mom, and of course Ethan!"
"And I want to fuck Katie and Mom," Ethan added.
Their mom raised an eyebrow and smirked. "And I want my children to one day become productive members of the society," she said pointedly, but soon she couldn't resist an amused chuckle. "Well, that, and of course for the three of us to keep fucking each other silly!"
Katie threw her hands up and cheered, allowing her brother to really maul her round, shapely boobs. She jumped and rocked on his lap, and soon the two of them lost track of the conversation as they began to focus more on their ongoing coupling. His sister gyrated on top of his throbbing dick, squeezing it with her sleek pussy muscles, while Ethan's fingers were busy rubbing and pinching her pencil-hard nipples.
"Hmm, yes, I guess that *does* help," Linda admitted, watching her nude, lewdly groped daughter as she writhed on her brother's lap. "At least we know where we stand, huh?"
"Ooooh, yes," she moaned, not really trying to reply to her mother. "What... what do you mean, Mom?"
"Let's face it, sweetie: we have become a family of completely unabashed, incurable sex maniacs," Linda declared, a narrow smirk on her face betraying there was more pride than regret in this statement. "That is just a fact, and we got to stop pretending that it isn't. I believe our journey of sexual exploration and discovery is therefore moving into a brand new territory. It is one where we take our little holiday adventure and turn it into a whole new lifestyle. In other words, forget about fucking all summer -- we need to figure out how we can do it all year long!"
A breathy gasp escaped Katie's throat, spurred equally by her brother's cock as it was by her mother's blatant admission. She agreed with her completely, and she knew that Ethan would concur as well. The fit blonde put away the fork and started vigorously bouncing on the thick shaft that was spearing her moist pussy. Her lover quickly took the hint and did likewise, bucking his hips and pushing his large cock even deeper into his sister's tight snatch.
Both siblings were now rapidly reaching the crests of their respective orgasms. Neither of them felt like they should put into any effort into delaying their impending release. Why would they? There was no reason why they shouldn't simply cum right there, sitting at the dinner table. Their mom had just officially declared that they were completely shameless sex maniacs, so they should wear this badge with pride and behave accordingly.
"Oooooooh! Yes, yes, yes!" Katie cried out, as the climax hit her tanned, nubile body. "Oh my goood... FUCK! I'm coming, Mom! I'm coming... right here... at... at... AAAAAAAH!"
Her brother wasn't far behind, and soon he let out a loud, savage groan. Head thrown back, he started filling his hot naked sister with blast after blast of his dense, virile seed. The base of his massive cock stayed outside of Katie's lewdly impaled pussy, so their mother could see the obscene throbbing of her son's manhood. Each time it shot its large volley deep into her squirming, still climaxing daughter, she would bite her lip and sharply inhale through her puffed nostrils.
"Aaaargh," Ethan grunted as he came. "Fuck, fuck, fuck... Hnnng!"
"Jesus," Linda whispered, furiously fingering her own dripping slit. "I thought I've seen a lot, but this... this is..."
Over and over, the immense fleshy pipe pumped load after load of thick, potent seed. It all went deep into Katie's wildly spasming vagina, as more than a dozen spurts erupted from Ethan's huge cannon. He let out a final grunt and relaxed, letting out a contented groan. He soon embraced his sister's lightly shaking body, as she came down from the peak of her own blissful release.
"Beautiful," their mother said, beaming a warm smile. The glowing of aura of post-coital bliss that surrounded her children was making Linda all so much warmer, a bit fuzzier, and much, *much* wetter inside. "Yes, this was really quite something... If you ask me, I think you kids are already embracing this new stage of sexual growth. You've just talked about 'toning it down', and yet you didn't even wait until dinner was over before cumming like total sex maniacs! Pretty crazy, even by your standards..."
"Yeah," Katie said, her breathing slowly returning to normal. "Crazy..."
"Crazy good!" Ethan added, which made both women giggle.
"By the way, speaking of growth," Linda said, momentarily putting on her typical motherly tone, "as your mom I have to insist that you hurry up and clean your plate. You kids need to stay healthy and strong, so that you can keep fucking each other like you clearly need to!"
"Yes, Mom!" said the kids, laughing as they once again picked up the forks.
"Good," she said, sliding the chair out to stand up. "And at the same time, as an avowed sex maniac myself, I'll have you know that I'm going to read and masturbate in my bedroom. If you come up with any ideas, or if Ethan's cock comes up, feel free to drop by, alright?"
As she left, swaying her wide hips and bouncing the large hemispheres of her naked butt, the siblings looked at each other and snorted another laugh. Their wordless agreement was that Mom was becoming downright lewd and slutty, and that it was unequivocally a good thing.
Eventually, they managed to finish their shared dinner, which by now had almost gone cold. To help their amazing mom with cleaning, they were very careful to not spill any of Ethan's abundant cum that was still corked up inside his sister's cramped pussy. To ensure it stays there, Katie expertly worked the well-developed muscles around her flooded tunnel, forcing the massive shaft of her cute brother to remain rock-hard until they both finished.
One appetite sated, it wasn't long before the horny siblings moved on to the living room satisfy a different kind of craving. Within seconds they were on the couch, with Katie's upper body thrown over the back and her hunky brother plowing her thoroughly soaked snatch from behind. He couldn't really see much other than the girl's firm, athletically sculpted ass; he was roaming about it with his hands while driving his cock with deep, thigh-slapping thrust. Ethan's sizeable pillar was gliding effortlessly in an out of his sister's hot pussy, lubricated by the voluminous load he had deposited there over dinner.
"Ooooh! Yes! Yeeees!... Fuck me, brother! Fuck your slutty, totally sex-crazed sister!... Yes, fuck me hard! I need your huge cock inside me, fucking me all day, every day!.... Ahhh! Oh my god... Fuuuuuuuuck!"
Her body cringed, seized by the power of a vibrating, full-body orgasm. She arched her back and lifted her body, bringing it briefly to her brother's eye level before falling back down again. He noted this with some amusement, eventually reaching down to lift his half-limp sister while still railing her cum-filled pussy. She was putty in his hands, moaning and whimpering in the throes of another shuddering climax, as her strong brother held her body below her perky boobs and continued to pound her sloshing wet hole.
A few minutes later, Ethan felt his building orgasm reach a boiling crescendo. He gripped her hips tightly and roared, electric pleasure coursing through his young male body as he unloaded even more cum into his sister's rapidly overflowing canal. There was no space for his copious jizz to go at this point, other than to spill out of Katie's thoroughly stuffed orifice.
And so it did, dripping down the leather upholstery of the couch. It added to the stains and blotches that were already there, from the teenage boy's vigorous rutting into his sister's cum-soaked pussy that had splashed his semen around, or made it run down Katie's smooth legs. Ethan kept coming for several more spurts, his kiwi-sized testicles still producing more than enough cream to fill the womb of his horny sister.
"Yes, yes! Fuck! Fill me up again, Ethan! Fill your sister's cunt with your hot, brotherly cum!... Oh my god, yes! I can feel it! I can feel it all... It's... OOOOOOH!"
Yet another orgasm ravaged Katie's body; this one was quick and almost brutal in its intensity. She caught up with her brother and they finished cumming roughly at the same time. Both breathing hard, Ethan helped his well-fucked sister up, then sat down on the couch and enjoyed a moment of rest after their erotic exertions.
Katie soon slid down the couch and cuddled with her handsome brother. She was feeling all tingly in the aftermath of her numerous orgasms. The two loads of cum that were leaking out of her pussy were making her feel extra affectionate in a very naughty way.
"I love you," she whispered, nuzzling into his neck while she played with his slippery, reluctantly softening cock. "Never stop fucking me, alright?"
They shared a kiss of sibling love -- their own unique kind of it, that was overflowing with incestuous lust and passion. It went on for a while, brother and sister enjoying their intimate closeness, slowly and languidly, without that frantic rush of arousal that characterized their fervent couplings. Their tongues intertwined in a sensuous dance -- not fighting for dominance, not even trying to excite each other, but instead hugging and caressing in an adoring, mellow fashion that would befit a kiss between lifelong lovers.
Well, almost -- with their insatiable carnal desires simmering just below the surface, this make-out session was obviously just an interlude. They knew it wouldn't be long, perhaps only a few minutes, before their mutual lust boils over and the incestuous couple starts fucking like crazy once again.
"So, my dear brother," Katie asked huskily, as she leisurely stroked his large and chubby dick, "when you do 'come up', do you think we should go check on Mom, or just fuck some more right here?"
He was gearing up to say something about his sister's unabashed sluttiness. She was already getting him hard again, despite god knows how many loads he'd blown into her and her libidinous mother over the last several hours. While the virile young man had always been able to cum frequently and repeatedly, it was only after they started going nude and fucking at the drop off a hat that his teenage male hormones went into uncontrollable overdrive.
These days, it felt like Ethan's massive cock hardly ever went down anymore. One of the main causes of this predicament was, of course, his wanton sister Katie. The blonde nymph wanted his rigid meat inside her on a constant basis; and, as her brother, he was only too happy to oblige. Like now, for example, when she was clearly itching to mount his recovering erection and sheathe it inside her sopping wet pussy.
But before she did that, as she maneuvered herself on the couch, Ethan realized he had a very promising idea. If it worked, then it might just solve the problem Katie had complained about earlier -- by giving his sister even *more* dicking that she oh-so-sorely needed...
***
When her kids finally appeared in her bedroom, Linda had high hopes. She was horny as hell, having spent the last hour in a horizontal position, with a vibrator in one hand and a smutty romance novel in the other. She had gotten herself off several times, squirming and writhing on the sheets, but in the end those self-inflicted orgasms mostly served to make her crave actual sex even more.
Yet, much to her chagrin, it didn't look like that was in the cards right now. Although the siblings were both smiling and laughing, and of course didn't have a stitch of clothing between them, Linda sensed they didn't actually come to instigate a hot threesome with their mother. Ethan's cock was only half-hard, a rare occurrence in itself, though it was firming up at the sight of his voluptuous mom masturbating naked on her bed.
"Oh, hey... What's up kids?" she asked casually, pulling the vibrator out of her leaking pussy. She openly stared at her son's large manhood, getting bigger by the second, as she hoped it would soon fill the void left by the buzzing toy.
"We've got something downstairs to show you, Mom," Ethan said, gaze flicking to the shiny plastic shaft his mom was holding. "It's, uh, about the stuff we talked about over dinner..."
"Oh," she yelped. "I... I'll be down in a moment, okay?"
Katie flashed her a grin. "Take your time, Mom!"
It took Linda a few minutes to compose herself, if that's what you'd call wiping excess fluids around her crotch with a napkin and brushing her disheveled hair. She resisted the temptation to lick the vibrator clean of her essence, knowing it would've likely made her horny enough to plunge it back into her sizzling hot depths. She was hoping that the business downstairs wouldn't take long, and that she'd be back here with her beautiful, horny kids, ready to fuck the whole night away in a blur of hot, writhing bodies.
With this salacious image in mind, she eventually came down and saw what the fuss was likely about. In the middle of the living room, their large, L-shaped couch was partially dismantled and rearranged into a new configuration. At first glance there was no rhyme and reason to it, which made Linda really curious what her crazy kids had in mind.
"Okay, this is interesting to say the least," Linda said, as she walked in. "So, kids, tell me. What exactly did you do to the living room? And why?"
"Living room?... No, Mom, this is a *study* room now," Ethan said, showing her a broad grin. "A shared one, for me and Katie. Here, let's have a look..."
He approached the strange contraption. Its largest element was the long section of the couch that he and his sister had just fucked on. There was still a trickle of half-dried cum running down the middle, and the cushions bore the indentations made by his knees as he'd railed her. This wasn't at all special, of course -- such stains, and other traces of unrestrained sex, were a frequent feature of every piece of furniture in their household.
The odd thing was how the couch was situated: away from the TV, facing a completely uninteresting wall. The shorter section had been detached and was now set back-to-back with the longer one. This part *did* face the TV, and it took about one-third of the length of the longer section. The remainder was taken by a simple IKEA desk Ethan must've taken from Linda's home office; its flat surface was rising to just a few inches below where the back of the couch ended.
Overall, it looked a bit like a waiting bench at a train station, one where people face away from each other. Except some sitting space was missing here, for it was inexplicably replaced by a seemingly unusable table.
"Basically, the idea is that Katie and I will be taking our classes here, together," Ethan continued, getting with his knees onto the couch cushion. "Sis? Can you demonstrate?"
Very intrigued now, Linda watched her nude daughter join her equally naked brother, as they both were about to show her this new innovation in education. Katie carried her laptop, which she promptly set upon the table, before clambering on the couch and bending over its back.
She was right in front of Ethan now -- or rather, her shapely butt was, with her shiny slit exactly at the level of Ethan's jutting cock. She put her hands on the table, opened the laptop like she'd normally do, and even placed her fingers on the keyboard like she was about to start taking notes. She waited a few seconds in this position, making sure her mother had a good look at the sinuously arching spine and the rest of her bent-over stance.
Eventually, she gave Ethan a sign by seductively wiggling her firm and perky butt. Her brother speared her pussy immediately.
"Oh?" Linda asked, trying not to laugh. "And what is that? Some kind of a learning aid?"
"Pre-precisely," Ethan replied, groaning through his grinning mouth, as his cock lodged itself inside his sister's silky folds. "Katie?... Can you, uh, tell Mom...?"
Freshly impaled upon her brother's sizeable erection, the girl wasn't really in any better position to explain things to their impishly smiling mother. She had to take a breath and bite her lip, just to gather the wits she needed to speak. This temporary daze was all due to his thick cock moving slowly inside her tight canal.
But then, once her young pussy gushed enough juices to make his invasion rather less overwhelming, Katie began the moan out an explanation. "Sooo... This is how Ethan and I will do... oh!... will do our coursework. I... I'll be on my computer here, listening to lectures or whatnot, and he will... ooh!... he'll just keep fucking me... throughout..."
Linda arched her eyebrow. "And that's going to help -- how?"
"Well, Mom, uh," Ethan tried to answer, but the sensations of his sister's sleek glove around his shaft were hampering him somewhat, "I think it's kinda like with your job... Remember when you started working from home? I'd always try to fuck you, Mom, even when you were on the clock! And I was, uh, pretty insistent, too, so eventually you just gave in..."
She snorted a laugh. "Yeah, 'insistent' is one way to put it," she said, smirking lasciviously, as she crossed arms under her spilling bosom. "And you still do that, by the way. You just come up from behind and shove your big cock in, and I have no choice but to try and do my job with my horny boy inside me!"
A huge grin appeared on her son's face. "And you're doing just fine! See? That's the point, Mom..."
Linda blinked, her mind having at last made the connection. "Ooooh, I get it!" She giggled. "My sex maniac of a daughter will now attend classes *and* get railed by her beloved brother, all at the same time! How convenient. Let's hope she can multitask well, eh?"
"Ooh, Mom... I can do that... just fine," the slutty blonde moaned. "Ethan's dick... when it's going in and out of my pussy like that... It's positively meditative!"
Both her mom and brother snorted a laugh. Truthfully, though, Linda had a reliable inkling what her daughter was referring to. A skillful lover like her son, whom Katie had trained into a well-oiled fucking machine over those past few months, should be able to do this easily. He would maintain just the right pace, that'd keep his partner on the thin line between boredom and spiraling arousal for hours on end.
He'd sometimes do that with his mom, actually, if she really pleaded with him and convinced the stud that her current work task was especially important. She'd always have to take a royal pounding afterwards, of course, but still!
"Alright, I suppose this checks out," Linda said, as she watched those mesmerizing, meditative thrusts of her hunky son into the fit, limber body of his sister. "But then, what about Ethan? He's got some coursework of his own, even though it may not be as demanding as yours..."
"Eh, that's easy," he answered his mom. "The TV's right there; that's why we turned the couch around. And with this"--he leaned to the side to produce a wireless keyboard--"I can take notes, or whatever. I just need to put it on, ahem, relatively stable surface, which happens to be..."
"Your sister's sexy butt!" his mother finished for him, and chuckled. "Okay, this is amazing. It is exactly why I emphasize the importance of education! Look at you, son: this is just your first day in college, and you've already turned into a genius!"
Now Katie burst into laughter, and it sounded incredibly cute when punctuated by her frequent moans. Ethan was somewhat less amused, but he chuckled regardless, happy that their mom seemed to approve of her kids' unorthodox approach to college work.
"So, uh, can we try this out tomorrow?" he asked, regaining the pace of his thrusts after his mom's joke.
"By all means. I'm not a huge fan of how this setup looks right now but hey, if it works, it works," Linda said, shrugging her shoulders and sending her pendulous breasts into an enticing jiggle. "We can figure out the details later, like maybe order some new pieces online and putting them in Katie's bedroom. Come to think of it, there may be other places in the house that could use some refurnishing..."
Ethan flashed her a grin. "Thanks, Mom! Did we tell you already that you're the best?"
Her cheeks gained a cute, rosy shade. "Probably, but it's always nice to hear again," she said, biting her lip, as she fixed her gaze on the lubricious junction of his cock with her sister's snatch. "And, you know, there is always this one good way in which you can express your gratitude to your mother..."
The grin remained on the boy's handsome face, as he continued to drive his huge shaft into his increasingly loud sister. She was gasping and whimpering in pleasure now, evidently beyond that thin line, where all that awaited her was a spiral into delirious ecstasy brought to her by Ethan's pistoning rod.
...Except that he had just retracted it, leaving Katie's confused at the sudden end to her brother's energetic pounding. She gasped and groaned, propping herself up on the table and trying to twist her neck to look where her stud was gone.
She found him quickly, embracing their voluptuous mother, hand sliding down to squeeze the soft pillows of her asscheeks.
"Ethan! What the hell?! Why did you stop fucking me?"
"Oh, come on, sis!" he called to her, with a raunchy smirk and a wave of his other hand. "Don't be so selfish! You'll be getting a lot more of my cock starting tomorrow. But Mom needs some loving *right now*, so come on, let's give it to her!"
Katie grumbled, but did not say anything more. Letting out a somewhat frustrated sigh, she scrambled back to her feet and followed her mom and brother upstairs. They soon arrived in Linda's bedroom, which the three of them wouldn't leave for the rest of the evening and night.
***
Over the next few days, a new and improved daily schedule would be crystallized for the self-proclaimed family of incurable sex maniacs. It was one that fit this moniker to a T.
All three would wake up, usually in Linda's bed, and immediately start having sex again. Sometimes, it would be Ethan sticking his huge morning wood into either his mom or sister, and the lustful moans and the squeaking of the bed frame would inevitably wake up the other woman. Other times, Katie's mouth would act as an alarm clock for her younger brother, and after swallowing his overnight load she'd purr sweet and horny nothings in his ear while impaling herself upon his rigid manhood. Their mom, who liked to sleep in, would usually have to wait for her kids to finish their first tryst of the day. She'd be rewarded with a massive load of her son's tasty seed, which she'd eat straight from her daughter's pussy while getting pummeled with his enormous cock.
The horny trio would then move to the bathroom and jump under the shower, where they'd continue fucking until such time that both pussies happened to be clean of Ethan's cum. Breakfast was next, which Katie would gobble up in her usual position: sitting on her brother's lap, speared with his huge rod, slowly fucking herself with it; all while they'd both eat the scrambled eggs and sausage patties served them by their caring mom.
Ethan would go work out in the basement gym for the following hour. During that time Linda would attend the daily stand-up meeting at work, while Katie would attend to the boundless needs of her insatiable pussy. Incidentally, this marked pretty much the only time that the siblings would stay apart from each other, exactly as it had been during their summer break of unrestrained sexual exploration.
Their study setup hadn't been without some teething issues, such as the discovery that they had to add some extra tables for the water they needed to hydrate them throughout the day. Also, once Ethan finished his classes on the first day, he became a bit of nuisance for Katie when he started to pound her soaking wet pussy for real. She almost didn't notice at first -- so accustomed she was to getting steadily railed by her brother -- until a powerful orgasm overtook her body while she was trying to take some notes.
It was then that she had to remind him what the shorter part of the couch was for. They switched around and he was made to sit there, with Katie watching the remainder of her lectures on the TV. She was rocking back and forth on his erect cock, giving out sultry moans, while she was also enjoying the groping attention of her brother's hands, cupping her shapely breasts and teasing the engorged nubs of her clit and nipples.
Curiously, their mom's earlier advice had now become feasible for the inseparable brother-sister duo. They found some shared gaps in their respective schedules, during which they were able to sneak a quickie, just like Linda suggested. In their case, it meant upping the intensity of their continuous yet languid mating into a veritable explosion of untamed, carnal passion. They'd go at it until they both came, then return to the previous pace of their ongoing, leisurely coupling.
In the meantime, their mother would be working in the home office while dealing with household chores on the side. The moment she was done for the day, however, she would jump on her son's persistently erect cock and have him fuck her to several screaming orgasms. Her daughter would be made to eat the creamy deposit of Ethan's virile gonads, which the taller blonde would do with gusto, usually while receiving another raw pounding from her astonishingly capable brother.
The ensuing session of incestuous sex between the siblings would inevitably drag on until dinner. On Friday, at the end of their first week in school, they were still rutting quite energetically even as their mom placed before them a large plate of food. Ethan would dive into it quickly but Katie, who was bouncing on his lap and swiping her clenching pussy up and down his rigid tumescence, seemed too preoccupied to so much as pick up the fork.
"Eat, honey," her mother nudged her. "Aren't you hungry, after all our exertions?"
"Ooooh... Sorry, Mom," her daughter moaned. "You're right! I'm just, uh... so excited... oh!... about tomorrow..."
Linda nodded, a warm smile coming over her face. "Yes, it's finally the weekend. Been a long couple of days, wasn't it? Any special plans?"
As soon as the question left her mouth, seeing the obscene sight of her daughter being lewdly impaled on her son's hugely erect cock, the perceptive mother immediately realized what the answer was going to be.
"Oooh, Mom... Isn't it obvious?" said the squirming girl, her voice trailing into a breathy string of moans. "Ethan and I... gonna be fucking... all day..."
Still, Linda's eyes did go wide. It was clear that her sexually liberated kids wanted to revert to their old habits at the earliest possible opportunity. The week that had just passed might've been too insignificant to make any difference in their attitudes towards this... 'experiment' of theirs.
"Really?... But you know it's not your summer break anymore, right?" she asked, her brow becoming lightly furrowed.
"It is not... But we can... oooh!... we can still do it," Katie replied, through gasping breaths. "There is still this... fire within us, Mom! Don't you feel it, too?... We can barely... keep it contained... and it feels so good... to let it burn!"
Linda let out a half-intrigued, half-dismissive scoff. She appreciated how her brother's immense cock could apparently make Katie speak in evocative metaphors. At the same time, being her mother, Linda wasn't quite convinced whether this justified the horny girl taking a solid reaming from said cock at all hours of the day.
Linda did get it, though... They were still incredibly young, absolutely brimming with sexual energy, and going through the kind of erotic awakening that was only possible in a supportive, familial environment. Just looking at them now: always naked, completely uninhibited, having sex right before her mother, cumming loudly and without shame, proudly declaring their intent to fuck as much as possible --
"Oooh, oooooh, oooooh!... Fuck me, brother! Oh my god! Fuck me, fuck me, fuck me, fuck meeeeeeee!... Yes, yes... YES!.... YEEEEES! OH MY GOD! I'M CUMMING ON YOUR HUGE COCK!"
Linda gasped. It was so utterly *beautiful*. She knew that even if Katie insisted Ethan was only her 'brother with benefits', they were confessing pure, unadulterated love to each other. It just so happened that they were expressing it by rutting like animals morning, noon, and night!
Still, though...
"Alright kids, you might be onto something," she admitted, before switching to her motherly tone. "But guess what? You still have to *eat*!" She pointed at the largely untouched plate. "And, you know, maybe also have some kind of life besides just --"
"Yes, of course," Ethan seemingly agreed, picking up his fork and also Katie's, then waited for his sister to calm down. "Like you said earlier, Mom, we're still figuring this one out. It's all cool!"
She smiled, and the sigh she gave was rather gentle and quiet. Perhaps it was best to just let this play out naturally. They had already managed to incorporate college classes into their... routine, so maybe it really *was* possible to turn their summer madness into some semblance of a viable lifestyle?
"Fine," she relented. "We'll figure it out then."
Besides, as her pussy would readily confirm, there was certainly a lot of benefits to being a family of incurable sex maniacs.
And Linda wasn't about to pass them up!
Friday started for Ethan the same way his past few days did. He woke up with a parched throat, a dull ache in almost every muscle in his body, and of course, a huge hard-on. Lolling his tongue around, in the vain hope to make his mouth feel less like Mojave desert, he made a mental note to haul a few more gallon-jugs of water to his bedroom. Hydration was important, especially during long stretches of physical activity; and lately, Ethan had been getting more exercise than he ever did in the entire eighteen years of his life.
Raising his head slightly, he looked around the bed and smiled. Next to him was his beautiful older sister Katie, happily snoring away as she lay on her stomach with the legs spread out. Ethan could just about spy the puffy purple lips of her labia, along with a thin streak of dried cum connecting it with the crusty puddle beneath.
This has been his final load from yesterday, deposited inside his sister's pussy only moments before they both drifted to blissful sleep. Seeing her like this, naked and leaking his own seed, made Ethan's cock twitch with desire as he recalled their last steamy session of the day before.
He and Katie had been having sex for several days now. It started about a week into the summer break, shortly after Katie came back home following her first year in college. The siblings' incestuous liaison wasn't at all a secret: the very first day it began, they were actually discovered in the act by their mother.
Thankfully, she was open-minded enough to realize there was really nothing wrong with it. It was merely her kids acting on their strong, physical attraction to each other. Being a good mother, she wanted to support their choices, regardless of what the wider society would think about them. She therefore fully approved of their taboo relationship, and even went so far as to accommodate the highly unusual way in which they wanted to conduct it.
The arrangement was originally Katie's suggestion, but it was hardly surprising that Ethan agreed to it in a heartbeat. Though it was ostensibly for his benefit, as a recent virgin who needed to learn more about sex, his sister was equally excited about him keeping his part of the deal.
To put it simply, the horny siblings agreed to remain nude at all times, allowing themselves unrestricted access to each other's bodies. Any time Ethan was around Katie, he was free to grope her, feel her up, squeeze her hard nipples and finger her wet pussy, or to do anything else he felt like doing to his sexy, naked sister. In turn, she was allowed to take the same liberties with her brother, which could go all the way to surprise blowjobs and just regular, full-on sex.
These were the rules by which they wanted to carry out their incestuous affair, and what followed as a result had exceeded their wildest expectations. Although they had been some very horny teenagers already -- Ethan jacked off religiously, while Katie had many sexual partners -- it was nothing compared to the way in which this total sexual freedom had affected their libidos.
On the very first day, the siblings had sex so many times that Ethan decided he must get in a better shape, just to make it less physically taxing on his body. Then the next day, he and Katie fucked through all of morning and most of the afternoon, until Mom came home and treated their children to a delicious dinner. Amazingly, they actually fucked *while* eating it, too: with Katie slowly rocking on Ethan's lap, his hard cock firmly lodged inside her dripping wet pussy.
From there on out, the insatiable lovers had sex pretty much all the time, fucking like rabbits in every spot of the house. Their mom had been extremely accommodating of this "experiment," as she called it, and normalized the fact that her kids were now rutting openly like wild animals, often in full view of their mother!
Totally supportive of their sexual self-discovery, she served them food, made their beds, and cleaned every mess they'd make while fucking each other for an entire day. Moreover, she actually expressed interest in the particulars of their lurid activities, not unlike a mom who would want to know if her kids are doing well in school. She always asked if they felt like they were making the most out of this opportunity, to explore their sexuality by letting their desires run completely free.
To Ethan, the answer was obviously a resounding yes! Every now and again, he would still get this feeling that it was all just a wonderful, erotic dream. Ever since Katie gave him a free pass to fuck her whenever he felt the urge, it seemed like all he'd been doing was thrusting his large cock deep into her heavenly tight pussy. With his teenage hormones in complete overdrive, he was always hard and horny for his hot sister.
Just like now, when he saw her stir and slowly open her eyes; Ethan's cock was already throbbing with anticipation.
"Mmm..." Katie purred sleepily, twisting her head as she followed her brother's movements. He was on top her now, his big stick poking at the entrance to her warm tunnel, while he kissed her neck and gently nibbled at her ear. "Ooh, Ethan..."
"And good morning to you, sis," he whispered, rubbing the tip over the moist lips of her pussy.
"You can wake me up like this any time," she said between ragged breaths, her slit quickly lubricating itself in response to Ethan's prodding. "I just love your hard cock, bro!"
"All for you, Katie," he said, bathing his shaft in her leaking juices but carefully avoiding the entrance to her sizzling hot furnace. "Since my slutty sister likes my cock so much, let me just make sure that everything down there is well acquainted with it..."
He continued daubing his rigid meat in his sister's copious moisture, making her give frustrated groans.
"Please," she breathed. "Don't tease me! I'm already so wet... I need you now!"
Taking matters in her own hands (or lips), she lifted her butt and pushed against her brother. Surprising Ethan with her craftiness and agility, she then caught the head of his swollen cock and sheathed it inside the opening to her vagina.
Amused by her eagerness, Ethan let out a breathy chuckle. He braced himself against the bed and pushed the rest of his rock-hard shaft all the way into his wanton sister, making the horny girl squeal in delight as he started rhytmically fucking her again.
***
Linda sat on the couch and felt like she was about to explode.
Normally, she'd be looking forward to the weekend. It was two whole days of respite, away from her stressful, though admittedly rather satisfying job. Especially weekends like this one, when she wasn't on-call, standing by to jump in and douse whatever virtual fire threatened to engulf her company's servers.
Yes, normally a weekend like this would be the perfect time for some cozy rest and relaxation at home. But for the past few days, Linda's home had been anything but normal.
"Yes! Yeees!... Oh my god... Fuck me, Ethan! Fuck your sister with your big cock!... Yes, ooh, yes... oh... Fuuuuuuuuck!..."
She could scarcely believe it. Her teenage kids had been going at it for literal days now, and it was slowly driving Linda insane. No, she didn't have any problem with her children having incestuous sex. What she couldn't stand was the fact that they weren't also fucking *her*!
In a way, she only had herself to blame. She really did everything she could to accommodate their torrid affair. She was acting on a faint hope that by involving herself in their sexual activities, if only from the sidelines, she would make them see her as the hot and horny woman that she was.
Lately, she even stopped being in any way subtle, as her wardrobe at home now consisted of a sports bra and a pair of ass-hugging shorts. Every day over dinner, she would listen to lustful moans that punctuated their eager recollection of the ongoing debauchery they engaged in. And she would drop one suggestion after another: that maybe, just maybe, they could think of even more ways to "explore their sexuality."
And yet, nothing had worked! As far the siblings were concerned, she was simply their very cool mom, strict about grades but super lenient about everything else.
Linda was fed up with it. She decided she was done with being just a mother. By golly, she deserved some of that sweet "sexual exploration" herself!
"Kiiiiiiiids!" she yelled. "Movie night!"
A movie night on Friday was their family tradition, or at least it had been before Katie went off to college. An old-fashioned one, perhaps, but it still worked just fine in the age of internet, flat screen TVs, and streaming apps with huge libraries of content.
Today, however, Linda didn't care much for a movie. What she needed was a pretext, to get her sex-crazed kids to come downstairs and sit with her for a while. Sure, there would be some Netflix involved, but the real point was the chill.
"Uhm... you called us, Mom?"
There they were, still naked as jaybirds. Ethan's cock was sticking out at a right angle, slick with what Linda was sure were the pussy juices of his slutty sister. Katie was with him, of course, holding her brother's hand and eyeing his shaft longingly.
"Yes," Linda replied. "Now that Katie would be home for a while, I figured that we could have our traditional Friday movie nights again. You know, just like the old times." She patted the couch invitingly. "So, why don't you sit down? I've got some snacks ready, and we can pick a film that we'd all like..."
The siblings looked at each other, shrugged, and wordlessly decided this wasn't the worst idea. Ethan went first, sitting maybe two feet away from his mother, followed by Katie who, pretty much reflexively, straddled his brother's lap and began to lower herself onto his pulsing hard-on.
"You may want to face the TV, honey," Linda said with a laugh, causing her daughter to blush and quickly change position. "Alright, I think we are all comfortable enough..."
During the first ten minutes of the movie -- a run-off-the-mill action flick -- Katie and Ethan were actually paying it some attention. Linda seemingly was, too, although she often glanced at the leisurely mating couple.
Over time, however, the pace of action both on and before the screen would rapidly increase. Ethan's sister was now gyrating upon his rigid cock, the sounds of her lusty moans drowning what little dialogue the movie had. The boy was quite worked up as well, cum boiling in his bloated nuts, as he flicked Katie's clit with one hand and groped her ample breasts with the other.
Linda was now openly staring at her kids, who were screwing right next to her, the heat within her pussy growing with each passing second. Previously, she would've simply averted her gaze, trying her best to ignore the primal noises of their incessant fucking. Simply hearing it was hard enough already; watching too closely could make her do things, things she might later regret. But now, having cast her doubts aside, she *wanted* to do those things. Her only regret was having waited so long to do them!
So, she kept staring. And, very slowly, she reached into her shorts and found the hard, throbbing nub of her clit.
"Oooh, brother," Katie started to really vocalize her pleasure now. "You feel so good inside me... I'm getting close... really close..."
Ethan let out a low groan, his hands resting on his sister's hips. He knew he should hold off for a moment now, to allow Katie to reach the bloom of her budding orgasm. With a firm grip he steadied her movements, and his eyes searched for some non-erotic scenery to help him delay his own release. He happened to glance at his mom, a sight that should normally be ideal for this purpose, but his eyeballs almost bulged out when he saw how far from innocent the view was.
"Katie," he whispered, pointing to the side with a flick of his chin. "Look!"
There was no denying it: Mom was masturbating! She had a hand stuffed inside her snug shorts, rapid movement of her fingers easy to see under the tight fabric. Her eyelids were half-shut, breath getting quicker and quicker as she worked herself towards a powerful climax. To reach it, she clearly didn't even need to watch her children anymore, though she was still straining her ears to catch the lewd sounds of their incestuous coupling.
But the noises were gone now. Her kids stopped fucking, and their attention was now all on her.
Linda opened her eyes and immediately met the gaze of her daughter. She was no longer riding Ethan and instead watched her mom with a surprised, curious, and intensely lustful expression. For a moment, they both froze.
But then Katie flashed Mom a huge grin, and soon started grinding against her brother again. Every now and then, she would glance at her mother and smile, locking eyes with her as she groaned at the feeling of Ethan's thick cock stretching her insides delightfully.
Linda's heart was racing: she was finally getting somewhere! Trying not to appear too excited, other than from her arousal, she gingerly went back to stroking her inflamed pussy. Her children were once again mostly focused on themselves and their mutual lust, but both of them would occasionally gaze at their mom and smile.
No words were said. The TV was still on, but no one was paying it any attention. Linda's loud moans, Ethan's grunts, and Katie's cries of pleasure filled the air of the dimly lit living room. The whole family was now building up towards a huge climax, together climbing their way to the peak of their shared ecstasy.
"Sis... I don't think I can hold it much longer..."
"Just... a little... more!... oh... oooh... oooooh!... OOOOOOOOH! OH YES! OH GOD! I'M CUMMING!... I'm cumming, Mom!! I'm cumming so hard on your son's huge cock!"
Katie cried out her release, trembling and squirming as the violent orgasm ripped through her young body. Her arms flailed, looking to grip something that could steady her through the overwhelming experience. Instinctively, Linda reached out with free hand and caught her daughter's arm, holding her firmly as the girl kept spasming and crying out in orgasmic bliss.
"AAARGH!" Ethan let out a savage growl. "I'm coming... too!..."
His sister's wildly quivering pussy was instantly flooded with Ethan's massive load. Just like Katie, he kept coming and coming, blasting her love canal with a great torrent of white hot cum. The rich seed soon leaked from her overflowing vagina, ejected by the forceful convulsions of her ongoing orgasm. It dribbled down Ethan's rampant cock and trailed further, forming a small but growing puddle underneath the shaking couple.
"Oh my, Ethan..." his mom spoke in a quivering voice, "this is so much cum!... You'll stain the couch... Oh god, it's so hot..."
Horny like she hadn't felt in years, Linda fingered herself furiously, her own release so close at hand... Her children were still cumming when their mom finally added her voice to the lewd chorus, moaning throatily at the apex of her long-deserved orgasm. Clad in a skimpy sports bra, her plump breasts shuddered on the waves of carnal joy, and she slid limply, momentarily paralyzed by the sheer intensity of her spine-tingling climax.
Linda's shorts were a complete mess, drenched in copious juices from her gushing pussy. To the side, her insatiable children were sitting in a puddle of her son's cum, panting heavily after cumming right along with their mother. The movie, long forgotten, was still playing on the big screen, the main protagonist now involved in some kind of a car chase.
But it all didn't matter.
What mattered was that Linda and Katie were still holding hands. Mother and daughter have at last come together, revealing to each other the incestuous desires that they both shared. Their son and brother was right there, too, ready to begin with them a new chapter in their voyage of sexual exploration.
"Well!" Mom finally said, relieving the lingering tension with a good laugh. "I'd say this was the best movie night in ages!"
***
Linda opened the door to her bedroom and flicked the light switch on. She turned back and cheerfully invited her slightly nervous children to come in. While they had obvious reasons to hesitate -- Mom's bedroom had always been uncharted territory -- it was clear that what happened between them was about to change things.
A lot.
"You can sit there," Linda pointed to a cushy armchair in the corner. "Ethan should be quite accustomed to having his sister on his lap by now," she added with a smirk.
Emboldened, the still-naked duo took the proffered seat, but Katie didn't impale herself on her brother's cock right away. Instead, she let the erect shaft jut from between her legs, resting against her pussy and lubricating itself with her juices. A cute yelp escaped Katie's lips at the contact with Ethan's hard-on, but the horny siblings were otherwise quiet and still.
"I've been awfully patient with you kids," their mom began, facing them as she sat on the bed. "I accepted that my son and daughter were having a sexual relationship. I've tolerated you having sex not only when I'm at work, but also in the evenings. I agreed to the idea of the two of you going nude, of you fucking all over the house, and even of you doing it right in front of me if you wanted to," she paused for a breath, looking at the increasingly disquieted faces of her children.
"I've been very accommodating, feeding you and cleaning after you, so that you could stop worrying about everything else and focus exclusively on your, ahem, sexual growth and discovery... And you've been doing just that, haven't you? For the past week, you've been going at it practically nonstop! I doubt you've ever gone more than an hour between your, uh, sessions, and it's an hour only because that's how long Ethan usually works out. You really want to spend the entire summer on nothing but sex, huh?"
Though the answer was obvious to them, the siblings weren't so sure, not anymore, that their mother would like to hear it again.
"We... kind of do, Mom," Katie tried it anyway. "When I saw Ethan's cock and realized what a stud he was"--her brother's face lit up with a cheeky grin--"I simply wanted him to be my fuck-buddy. But once we actually started having sex, and we stopped wearing clothes and all that... Well, it just got crazy! It's so naughty and exhilarating, to know that we can just fuck each other at any time. It's like we both know that even if we're done for the moment, it won't be long before one of us wants to go again. So, why even stop?" Katie asked with a disarming smile. "Well, okay, I'm sure we'll eventually calm down somehow, because nothing this good can last forever. But I don't want to think about it... Right now, Ethan and I are simply loving this, and we absolutely want to continue."
Ethan was nodding along vigorously. He wasn't completely sure he agreed with everything his sister told Mom, particularly the part that predicted the eventual end to their activities, but he sure as hell wasn't about to contradict her. For now, Katie was taking his throbbing dick inside her pussy at all hours of the day so, in his view, this made her correct about pretty much everything.
"Huh, okay," Linda said hesitantly, trying to not to show how jealous she was of this passion between her children. "Well, if nothing else, I suppose it's a fun way to spend your summer break. Just make sure you *do* calm down at some point, alright?"
"We'll try," Katie said, looking at her brother who understandably didn't want to commit to anything. "But right now, we are just super horny. Leave us to our own devices, and we will be fucking all day, every day! I guess you know that already..."
"Yes, I've noticed," she said, a soft sigh escaping her lips. "It has been rather difficult to ignore. Sometimes, I would get frustrated enough to think you are doing this on purpose. I'm sorry, I know it's obviously not the case, but I was just --"
"Mom," Ethan spoke up, and swallowed, "we were actually, kind of, trying to fuck in front of you. But it was"--he wanted to say 'Katie's idea', but he caught himself in time--"uh, it was because we thought... uhm... that you would... enjoy it."
"Pretty much," Katie jumped in. "You just never told us to go away, or to be quiet, or anything like that. Now I feel bad since it was obviously, uh, affecting you... But we had no idea! Why didn't you tell us, Mom? Ethan has been dying to fuck you!"
"I didn't tell you..." Linda muttered reflexively, then froze as her daughter's words sank in. "WHAT?! Since when? Ethan?"
He stammered, biting his tongue not to say 'always', "Since, uh, you caught us fucking, Mom..."
Linda blinked, several times, then out of nowhere bellowed a fierce, almost savage cry.
"OH MY GOD!"
Her kids jumped, looking in shock at their mother whose fists were slamming the mattress in frustration. "M-mom?" Katie asked with obvious concern.
But Linda didn't hear it. Not when she was letting out all the anger and frustration that had built up in her all throughout the week. All the simmering horniness, all the unrequited desires, all the dissatisfaction and continued disappointment, and the ever-growing, wistful longing for good, hard, wild fucking!
It felt incredibly liberating to finally release all these pent up emotions. She knew that she could at last rectify this awful, horrendous, terrible misunderstanding that plagued the incipient sexual relationship with her children.
Eventually, getting a little winded from her outburst, Linda threw herself on the bed. She lay on her back, motionless, her substantial chest heaving as she stared at the ceiling.
"Mom?... Speak to us, please!"
Linda took a deep breath, feeling the warmth spread from her lungs and course through her body, settling in the area between her legs. The (fresh and clean) booty shorts she was wearing suddenly felt unnecessarily constricting. Having unleashed her bottled-up exasperation, she was now yearning for a different kind of release.
"Tell me, kids," she finally spoke. "When Katie said that you want to just keep fucking, was it exclusively about doing it with each other?"
The siblings exchanged surprised looks, then a wide smile, and finally a hearty chuckle.
"Not necessarily, Mom." she said, feeling a rush of heat that further warmed her already balmy pussy. "I love fucking Ethan, and I've been worried he would eventually find someone else and lose interest --"
"Sis! I would never --"
"-- but," she continued, hushing him with shoulder rub, "as long as he sticks his cock inside me whenever I need it, I'd be thrilled to expand our horizons... Why, Mom?" Katie asked with a mischievous grin. "Do you have someone specific in mind?"
Not taking her eyes off the ceiling, Linda smiled the most wicked, satisfied smile that could fit on her pretty face.
"Yes."
***
It was just like in Ethan's fantasy. Except better.
Mom was on all fours, her lush naked body glistening with a thin sheen of sweat; it coated her pale skin and condensed into droplets as she jerked, shuddered, and writhed in pleasure. Her swaying breasts, large and squeezable pillows of luscious flesh, were grazing the mattress with their pencil-hard nipples, sending electric pleasure right up her arching spine.
Behind the wanton mother was her own son, plunging ten inches of rigid cock-meat into the sizzling hot depths of her mature, yet divinely tight pussy. The eager boy was groaning, as the clenching vagina gripped his retreating ramrod, pulling him back into the very womb that birthed him.
"Wow, Mom," said Linda's excited son. "Your pussy is squeezing my cock so fucking good!"
At the same time, his mom's curvy butt cheeks rebounded from his savage thrusts, jiggling as he slapped into her meaty thighs. His virile gonads, both the size of golf balls and filled to the brim with his thick seed, swung wildly as he plowed her dripping snatch, now and again hitting her sensitive clit for another, sudden jolt of pleasure.
"Oh fuck, this is great," the boy moaned throatily. "You are so wet, it's practically dripping over my balls!"
Linda couldn't audibly moan how incredible it felt, to have her son's enormous dick slide in and out of her sopping wet cunt. She couldn't cry out the ecstasy that was building inside her, and the ecstasy she was already feeling as Ethan fucked her to oblivion. All she could do was savor it, just like she savored the creamy, sweet and salty ambrosia that filled her mouth with every lap of her tongue.
Linda's head was being held in place by her daughter's hands. It was the girl who was crying out in pleasure, throaty moans mixed with shrieks and whimpers; the ebbs and flows of her ongoing climax. Recently flooded by her brother's deluge of semen, Katie's pussy was now being thoroughly cleaned by her Mom's eager mouth.
"Ooooh, right there, Mom... YES! OH FUCK! OH GOOOOOD... Keep... doing that..."
The horny mother couldn't be happier to oblige. Finally, she was exactly where she wanted to be: with her amazing, beautiful, sexually insatiable children, all three of them sharing her large bed and engaging in mind-blowing, incestuous debauchery.
No longer would she have to only watch and listen, while the unstoppable siblings shook the house to its foundations with their endless, vigorous rutting. Linda was about to become a regular feature of the brother-sister couplings, to an immense delight of both her big-dicked son and her feisty, nubile daughter.
"FUUUCK!" Ethan roared, his climax striking him almost without warning. "I can't... hold... Oh fuck! I'M COMING, MOM! YOUR SON IS CUMMING INSIDE YOUR TIGHT PUSSY!"
She let out a muffled squeal, as Ethan's large spurts whitewashed the sperm-deprived insides of her steamy vagina. The numerous blasts coming from her son's prolific cum-cannon sent her spiraling into an orgasm of her own. She practically gurgled on her daughter's gushing juices, gasping for breath as the momentous release took over every nerve in her wildly quaking body.
"Ooooh yes...." Katie moaned. "Cum inside Mom, Ethan! Fill her pussy with everything you got!"
The trio groaned, relishing their generously shared orgasms. The peak of their pleasure was marking a new beginning for the whole family. From now on, all three of them could enjoy the carnal delights together, no longer feeling frustrated or left out.
"I... I can't believe... you kids are doing it... all the time..." Linda said, gasping, as she lay exhausted next to her smiling daughter. "I'm gonna need to... get used to this..."
Katie just giggled. "Don't worry, Mom," she said, beckoning her brother and spreading her legs invitingly. "As Ethan here can attest, it's all just a matter of training and practice!"
The boy just grinned, grasping his barely softened dick and lining it with the entrance to his sister's spotlessly clean pussy. Intimately familiar with her sexy body, he knew just the right speed and angle to make even the first stroke an exquisite pleasure for his horny sister. Katie moaned, yelped, then cried out in carnal joy, a mini-orgasm lighting up every nerve in her body for a brief, ecstatic moment. Locking eyes with her and smiling, Ethan began thrusting into her juicy warmth, slowly and more gently than the royal pounding he had just served their mother.
"Ooh... I'm feeling so nice and full again," she cooed, returning the cheeky smile. "Thanks, bro!"
"Everything for my hot sister," he said, giving her pussy a decisive stab that wrung a lustful moan from her lungs. "Told you I would never lose interest in fucking you!"
"Aww, you say the sweetest things," she said with a breathy laugh, then turned her head to Linda as her brother started to thrust into her again. "Mom? You are still full of Ethan's cum... and I know it's so yummy!... Would you mind... giving me a taste?"
Catching her breath, the mature woman stuck several fingers into the frothy mix of cunt juice and her son's sperm that was slowly leaking out of her gaping snatch. It coated her hand copiously, and Linda couldn't resist to sample it herself; the flavor was tangy but sweet, and she immediately acquired a strong liking to it. Eventually she scooped up more, putting her cum-dipped fingers in her daughter's hungry mouth and having her lick them clean of her son's delicious spunk.
"God, when did I turn into such a slut?" The mother laughed.. "I'm feeding my son's cum to his sister, straight out of my own cunt, while he is fucking her right next to me!"
The horny siblings chuckled. "Mmm... Pretty damn hot, isn't it?" Katie purred, patting Ethan's shoulders to ask him to slow down for a moment. "And tasty, too! I think I'm gonna need all of it, Mom..."
Linda didn't get it at first. "Huh? All of it?"
"Just sit on her face, Mom," Ethan nudged his mother, propping herself up and swinging his sister's legs over his shoulders. "Let Katie eat your pussy like she did yours."
Linda was being blown away by the sheer debauchery her children were asking her to engage in. The renewed ache in her cum-filled pussy, however, had already made the decision for her. Listening to her horny cunt, she easily found the energy to scramble back to her knees. She then swung one leg over Katie's head and, with only a slight hesitation, lowered her dripping snatch onto her daughter's lapping tongue.
"Oooh! Sweetie... This feels... Aaah!"
Within moments she was already shuddering in delight, falling forward on the bed and groaning from the fireworks of pleasure brought about by Katie's oral ministrations. She spread her legs and straightened her arms, her back arching at a concave angle, her sodden pussy forcing itself between the girl's smacking lips and even deeper into her mouth.
Watching it from a feet away, Ethan had to really slow down his deep strokes into Katie's sex. He was afraid that the unbelievably lewd scene -- that was playing out right there, at the other end of his sister's body -- would make him blow his load pretty much instantly if he dared to go any faster. This was beyond even the hottest erotic dreams that the teenager ever had. For a boy who had been a virgin less than a week ago, this straight-up pornographic, incestuous threesome felt like once-in-a-lifetime experience.
He refused to believe this just the first one of many, many more!
"Ooooooh! Yes!... Yes, yes, yes, yeeeeees!" his mother chanted, grinding her engorged clit against Katie's face that was buried between her thick thighs. "Aaaah! Don't stop! Oh god! Right... right there... EEEEEIIIIH!"
The sexually awakened MILF was emitting a whole spectrum of lurid noises, from quiet whimpers to loud, almost savage groans. Her daughter was playing her quivering pussy like an intricate wind instrument, each flap of the tongue producing a different yelp or moan from the straining throat of the wanton mother. Ethan's fierce grunts, though loud and raw, were merely a background track to Linda's aria of carnal pleasure.
"Fuck, this is so hot," he managed, as he bottomed-out inside Katie's pussy yet again. His bloated balls were close to fully loaded with another potent payload, and he was about to spray it wherever his women wanted him to. "I'm gonna blow soon! Sis...? Mom!... Where... where do you want it?"
"On meeee!" his mom wailed, barely holding on as a wave of sensual bliss washed over her almost exhausted body. "Cum all over me, Ethan! And on your sister, too! Just... cover us in your cum!"
Amazed at his mother's transformation into a shameless cumslut, Ethan was more than happy to listen to Mom. Feeling the surge of spunk rushing through his engorged cock, he pulled out of his sister's wet hole and aimed the spout of his firehose at her chest.
He roared when the first volley shot out of his pulsing shaft, splashing against Katie's smooth neck and her firm, heaving boobs. The next salvo went higher, hitting his mom's large and shaky butt. For the rest of his massive discharge, he went back and forth between both women, spraying many volleys of teenage jizz all over his mother and sister. The orgasm was so intense that it totally sapped his strength; he fell forward, bouncing off of Katie's thighs that he had slung over his shoulders. He finally rolled to the side, panting heavily as he lay on his back and allowed his racing heart to gradually calm down.
Linda had collapsed, too. She'd been overwhelmed by the final climax that her daughter gave her, amid the veritable rain of cum that her son precipitated upon their writhing bodies. Only Katie still had most of her wits about her, laying limp on her back and staring at the ceiling, gobs of Linda's pussy juice still smeared all over her face.
"Holy shit..." she whispered, and a huge smile appeared on her lips.
***
By the time the weekend was done, the entire incestuous family had gone through a veritable whirlwind of sex.
After the incredibly hot three-way romp on Friday -- a followup to the immensely successful revival of their movie nights -- Linda let the horny teenagers sleep with her in her own bedroom. In the morning, the siblings took advantage of this and were very quick to instigate another wild threesome with their mom.
This time, it was Ethan who got some much needed practice in eating out his voluptuous mother. She was sitting on his face and moaning in joy, while Katie rode his stiff wood and goaded Mom to make out with her daughter. Linda didn't have to be told twice, and she very much enjoyed the young girl's lithe body as it pressed against her own, more curvaceous one. Their delightful purrs and moans were making it a real challenge for the lucky boy underneath them to focus on the task of orally pleasuring his mom's pussy.
Still, he had done a very respectable job. It wasn't long before Linda cried out in a powerful orgasm, just as Ethan sprayed her daughter's pussy with his thick semen.
They later went for a quick shower and eventually returned to Linda's spacious bedroom, the siblings being quite eager to take their sexual exploration even further. The thoroughly satisfied mother wasn't as keen, though she was still amazed not only at the intensity of her children's lurid activities but also the ease with which they had drawn her into their erotic wonderland.
"You kids go off!" she playfully shooed them out of her bedroom. "I'll make myself decent, and make us a really large breakfast..."
"Uhm, Mom," said Katie, "now that we're all having sex, why don't you join us in this, too?"--she waved her hand about the nude forms of herself and her brother--"If you stay naked like us, then we can enjoy each other any time we want to."
Mom chuckled. "Honey, after today and especially yesterday, I couldn't possibly want to fuck you again so soon!"
"Oh, but you only think so now!" Katie said with a chuckle. "I'm pretty sure that once you do this, you're gonna find yourself just naturally more horny, like us!"
"Really? Is that how it works?"
Katie shrugged. "I mean, it does make sense that your body would open itself to the possibility of sex at any time," she reasoned. "Like, if Ethan can just take me any time he feels like it, then my pussy *needs* to stay wet for him, and it does! I can't see why the same thing wouldn't happen to you, Mom."
Linda shook her head in amusement, and laughed. "Okay, I suppose there is some logic in there. Guess I'll try it then, at least for today, and we'll see what happens," she said, dropping the towel that covered her and exposing her gloriously nude, voluptuous body. "There!... Now, since I'm skipping the 'getting decent' part, I'll just go make some food, alright?"
And with that, she sashayed out of the bedroom, her wide hips swaying enticingly. Ethan obviously found the sight enthralling, and it distracted him long enough for Katie to sneak up on him, push him onto their mom's bed, and mount his rock-hard cock again.
Wisely, the siblings gave Mom some space after their (nude) breakfast, though of course their incessant fucking continued unabated. Listening to her kids copulate upstairs like a pair of animals in heat, it didn't take long for Linda to feel an itch between her legs once more. She had an unpleasant flashback to her recent experiences of sexual frustration, so she decided to act on her urges right away.
And so, after lunch, they had another threesome.
And then one more after dinner.
On Sunday, following yet another menage-a-trios in her bed, every muscle in Linda's body was screaming from the physical effort. But rather than take it as a sign that she should perhaps slow down, Linda figured she could "rest" by spending most of the day on her back. She let her son and daughter use her body but only in gentle ways, with Ethan having a cozy, languid session with his mom in the missionary position.
Linda had to admit: her daughter was absolutely right. Going nude, and making her body sexually available to her kids at all times, had supercharged her libido to straight-up dangerous levels. On Monday, she dreaded going back to work like this, but she feared that excusing herself into her home office would only make it harder to go through the necessary adjustment period. Linda had quickly realized that she now had to balance her professional life against the urgent demands of her skyrocketing sex drive.
That first day was incredibly challenging, as she had to visit the bathroom about once every hour to relieve the ache in her overheated pussy. It wasn't until she came back home that Linda finally felt comfortable again, with every piece of her clothing promptly discarded, as she practically ran upstairs to impale herself upon her son's huge, unyielding hard-on.
It took her about a week before he learned to cope with her nigh-uncontrollable horniness at work.
In the morning, she would have Ethan and Katie focus mainly on her, kickstarting her day with multiple earth-shaking orgasms. Along with a vibrator always buzzing in her dripping snatch plus a strategic choice of wardrobe, this allowed Linda to concentrate on writing code while in the office, at least to a passable degree. All day long, however, she would look forward to the incestuous romps they'd have once she returned home.
In light of these development, Linda thought, she would probably need to reevaluate her career choices...

With a fierce grunt, Ethan let loose inside his mom's piping hot snatch. He erupted with several volleys of his dense cum and coated her womb thoroughly, then yanked his spurting cock and scooted up the squirming mother's body. He aimed the final salvos at her bountiful breasts, covering them in a thick layer of spunk, as she moaned in delight at her virile son glazing her with hot semen. Moving further up, he presented his dripping cum-cannon to Mom for cleaning, which she did immediately, inhaling it with great gusto.
"Mmm, delicious as always," she purred and giggled. "I just can't get enough of my son's tasty treats!"
"I should have more for you very soon, Mom," he said with a grin. "All you have to do is keep licking it like this..."
Ethan loved to have Mom in the house on a permanent basis. Several days ago, she switched from her old job to a different, fully remote position, that enabled her to stay home and take much better care of her kids.
Since then, the horny boy had been a constant, albeit very welcome nuisance to his mother. She was tempting her with his huge boner, just as she was trying to familiarize herself with the complicated production setup at her new company. Most of the time she would relent, letting him spear her wet slit with his dick while she struggled to maintain focus on the task at hand.
Yet, ironically, Ethan's rock-hard cock could be said to make Linda *more* effective at her job, not less. She could now solve many problems using maybe the fifth of her usual brainpower, with the rest devoted to enjoying the carnal sensations of her son slamming relentlessly into her juicy cunt!
