Little Sister's Big Butt Ch. 06

Sooner than both of them expected, the toe-curling yet so far sweetly stable rumbles of delight emanating from Michelle's cock-jammed anus reached a new vertiginous peak when her latest tiny assgasm unexpectedly swelled up to immense proportions and then exploded in the blink of an eye, releasing its orgasmic charge in a burst of butt-centric bliss that crashed full force into her petite frame without any preamble. As her pussy-diddling fingers twitched and froze in place on her engorged clit, Michelle's eyes blinked wide open and her melodious mewls of pleasure turned into a choked gasp and then into shocked silence for a moment, before a scream of incapacitating ecstasy erupted from her lips, coinciding with the crazy tightening of her orgasming rectum around her brother's enormous truncheon.

"Uuhh... Uuunghh! Fuuuh-uuhh-uuhhuuck!"

His sister's rapturous yells and the glorious image of her adorable face transfixed in a mask of indescribable anal pleasure had barely just registered in Tyler's ears and eyes when his boner was engulfed from tip to root in the deep, cock-milking pulsations that suddenly possessed Michelle's narrow anal passage. Despite having left his throbbing dickmeat pretty much fully immersed inside her steamy anus for the entirety of that impulsive buttfuck, and thus having enjoyed the enhanced tightness that her back-to-back miniclimaxes had imparted on her velvety anal walls, Tyler was instantly undone by the awesome shaft-squeezing intensity of the convulsive ripples that Michelle's final mind-melting assgasm generated in her already super snug rectum.

"Ohh Mimi! Fuuuck... Ooohh fuuuuck, Mimiiiii!"

Surging forth with the same quickness of his bestial growl of release, Tyler's ejaculation exploded inside Michelle's ass with such force and suddenness that he felt faint with pleasure and his vision blurred as a veritable deluge of creamy semen sprayed from his deeply buried schlong, painting his sister's buttery bowels white with cum. Bucking and throbbing and swelling impossibly bigger and harder against her soft dick-wringing anal walls, thus increasing even more the complementary delightful sensations of suctioning tightness for him and ass-stretching pressure for her, Tyler's horsecock pumped an almost continuous, obscenely abundant stream of warm sperm inside Michelle's orgasming rectum, the sheer amount of his load sending her lust-drowned brain into overdrive and adding yet another sweet layer to the forbidden, incredible pleasure she took in being sodomized and anally creampied by her beloved big brother.

Locked in their visceral embraced, his huge cum-spewing sausage buried to the hilt inside her overdilated shaft-constricting bootyhole, Tyler and Michelle kept moaning while their lips met and they initiated a passionate make out session that lasted all through their entwined climaxes. Even after Michelle's rippling rectum had stopped convulsing around his horsecock and a few final spurts of gooey seed marked the end of Tyler's ass-flooding ejaculation, the siblings kept smooching and licking and sucking on each other's tongue, barely pausing to take a few much needed breaths here and there, their shared afterglow egging them on to keep trading more loving kisses.

Eventually it was the lewd cock-hardening feel of creamy slickness surrounding Tyler's firmly slotted dong that broke the siblings' lip lock. Still hornier than he should reasonably have been given that he had just pumped a massive load up his sister's ass right after hosing down her throat with another equally copious batch of his brotherly seed, Tyler couldn't help but feel his buttlust resurface with a vengeance as the heavenly warmth and shaft-hugging tightness of Michelle's forbidden tunnel also gained that sinfully appealing, irresistible slipperiness that unavoidably occurred every time he creampied her ass, a sensation that always impelled him to start pounding away at her glorious bubble-butt again so that he could put the added lubrication he himself had provided to good use.

As his freshly spewed cum began seeping all around his hefty truncheon to envelop his pole from tip to root in the lewdly gratifying slickness of his own seed plastering his sister's soft anal walls, Tyler couldn't help but start humping back and forth, gently sawing his boner in and out of Michelle's cum-filled anus in slow fluid strokes that made her kiss-muffled moans instantly spike up in volume and pitch. Realizing that he just couldn't resist the urge to go for round two, Tyler chuckled as he pulled back from Michelle's umpteenth panting smooch to speak.

"Holy fuck, Mimi... This is so fucking awesome!" Tyler exhaled with deep satisfaction, his massive schlong sliding with fabulous ease into her sperm-lubed rectum, the added lubrication provided by all the girlcum that kept trickling over her tautly distended butt-ring further facilitating his pistoning motions and making his booty-cramming thrusts feel so deliciously smooth that he simply couldn't bring himself to stop. Somewhat perplexed, he laughed as he concluded: "I'm gonna have to fuck your ass again, Mimi! I just have to!"

The mixture of burning hot lust, matter-of-fact simplicity and ironic bafflement in her brother's tone made Michelle's naughty giggles resound bright and clear in the cramped confines of the car. Even as her laughter turned into gasping mewls of appreciation though, she willed herself to focus enough to look him in the eye and purr: "Oohh Ty... You know that my horny little asshole can never get enough of your big fat cock! But... Uuhh fuck yesss! I just think that maybe... Oowwhh god yeeesss! Uuunghh..."

Michelle's pleasure-dripping words were fading into bursts of sexy squeals already, but Tyler had guessed what she was about to say and promptly nodded in agreement while finishing her thought.

"Yeah, maybe we should go inside, right?"

"Yesss... Uuhhh yes!" Michelle replied, smiling impishly as her mewls of delight merged with her affirmative response, her sparkling green eyes casting a quick glance around before returning to lock with Tyler's gaze. "This is pretty hot, but not very comfortable. Oowhh fuck, yesss... But, uhm, can you stay inside me, please? I want to keep your cum in my ass and your big cock fills me sooo good..." she trailed off, giggling as she added with a coquettish shrug: "There's never a buttplug around when you need one, am I right?"

The siblings' chuckles filled the car all through the somewhat clumsy rearranging and shifting that followed as they tried to get out of there while remaining joined as they were. Eventually, to the sound of Michelle's sweet giggles intermingled with her sexy moans of anal delight, Tyler managed to exit the vehicle while she held on tightly to him, her legs wrapped around his waist, her arms thrown around his neck and her plump jiggly bubble-butt deeply impaled on his unyielding horsecock.

Hugging her in his powerful arms, glorying in the feel of her soft curvy body clinging to his muscular frame as her huge pillowy tits got smushed deliciously against his chest and her pink, engorged nipples brushed teasingly against his sculpted pecs, Tyler planted his hands possessively on the big fleshy globes of his sister's asscheeks and walked with deliberate slowness, all the while savoring the exquisite warmth and snugness of Michelle's sperm-coated anal sheath squeezing and sucking lewdly on his fat dong. In truth, Tyler was having a blast just making his way out of the garage and into the house with his amazing little sister's fabulous ass speared on his dick and bouncing gently against his groin in time with his steps, her tight little bootyhole sliding rhythmically up and down along the very last inches of his broad shaft. Her sexy moans and her labored breathing hitting his neck as she held desperately onto him added even more to Tyler's excitement, so much so that, as he crossed the kitchen and walked into the living room, he decided not to continue their buttfuck right there and then on the couch, but to head upstairs instead, just so that he could extend that ass-spearing stroll a bit more and soak in the cock-hugging coziness of Michelle's rectum engulfing his shaft and her overdilated butt-ring nursing on the root of his pole a little bit longer.

"We've got to remember to go get our clothes out of the car later!" Tyler suddenly said, trying to voice out that very crucial thought before it got irremediably lost in the rising fog of the asslust that was already clouding most of his rational brain. "Before Mom gets home, you know. If she goes into the garage and sees that, it would be really tough to explain why we left everything in there..."

Panting and mewling, her eyes half-closed and her pussy overflowing with girlcum as her big bubble-butt kept bouncing on her brother's ass-stuffing sausage, forcing his fully buried length to slide briefly out of her clingy sphincter only to quickly push deep into her anus again and stir her cum-coated bowels with his every step, Michelle was barely aware of what Tyler had just said as she cooed her deliriously enthusiastic reply.

"Oohh yeah... yeees, Ty! Uuungh yeees!"

Moments later, Tyler reached the stairs and began climbing them, his steps getting longer and his motions firmer, causing Michelle's fully impaled booty to bounce more intensely as his huge dickmeat pushed harder and deeper into her shaft-constricting forbidden chute. At that point, Michelle's words had no relation at all with anything else but the incredible pleasure she felt in getting her tight asshole crammed to bursting by her brother's horsecock.

"Uuhhh yees! Oooww fuck... Yesss! Uunngghh yeessss!"

*****

Even though the evening started with a fairly close call when, suddenly hearing their mother's voice echoing from downstairs, Michelle untangled her naked body from Tyler's safe embrace and reminded him in a panicked squeal that their clothes were still in the car, the rest of the night unfolded smoothly and was in fact very pleasant.

After a combined operation that involved Michelle distracting Ellie while Tyler sneaked out to the garage and collected their discarded clothes, the siblings felt relaxed enough to enjoy a nice family evening which, at their mother insistence, consisted of an awesome dinner at their favorite Italian restaurant. Indeed, having spent the hours between their return home from work and Ellie's arrival lustfully sucking and fucking on Michelle's bed and thus feeling in dire need of a robust caloric refill, the siblings were more than happy to comply with their mom's adamant proclamation that they should celebrate the first day of their summer jobs with a nice meal together.

On top of the delicious cuisine, what made Michelle and Tyler's dinner even more delightful was Ellie's unexpected and morosely exhaled announcement that the following morning she would have to go out of town for a few days on a last-minute business trip. Much to the busty mother's surprise, the siblings not only took the news with what she interpreted as rather impressive philosophical calm, but they also went as far as to cheer her up and laugh her motherly guilt away by saying that they would be okay, more than okay, and they totally understood her position. Sipping her red wine with a smile on her luscious lips, Ellie was almost moved to tears as she glanced at her kids trading jokes and teasing one another while sharing their food and tasting tidbits of their choice course from each other's plate. Their warm, unbreakable bond never failed to make Ellie feel good, and that was on top of the maternal pride that already filled her in light of the remarkable responsibility and maturity that Michelle and Tyler were showing by deciding to get summer jobs despite there being no real need for them to do so and no prompting on her part at all.

After dinner, when she was sitting in the back seat of her SUV while Tyler drove them home with Michelle sitting by his side giggling and teasing him with some new variant of their usual inside jokes, Ellie couldn't help but smile broadly and sigh with contentment as she considered how lucky she was that her kids loved each other so much and were so close and happy just to be together. It was a rare and precious thing, the drowsy mother pondered, and that comforting thought was still with her even later, lulling her to sleep and making her feel much better about having to leave early next morning and be away from her kids even longer than her usual work schedule forced her to be.

For their part, Michelle and Tyler did feel somewhat sad about their mom having to leave town, of course, but not too sad really. In fact, they felt almost guilty about how thrilled they were to have the house all to themselves for a few days. Ultimately, both their guilt and sadness were crushed into insignificance by their shared arousal and by the realization that, starting the following morning, they could let their roaring lust for each other completely loose at home and they wouldn't have to worry about sneaking around and being cautious like they were currently forced to do every night so that they could sleep in the same bed and have steamy buttsex.

Unsurprisingly, the siblings' plan to celebrate their mother's imminent business trip was to wait until Ellie fell asleep, dash to Tyler's room and fuck each other's brains out. Not only did their simple tried-and-true plan work like a charm, but they also got an unexpected cherry on top of their nightly ass-pounding session in the form of a video from Gabby.

Lying on her side in a snug spooning position with her brother's muscular body pressed firmly into her curvy little frame, his powerful arms holding her in a loving embrace and his massively huge schlong pumping steadily in and out of her sizzling bootyhole, Michelle was smiling and trembling and moaning her umpteenth climax of the night into the pillow when the chiming buzz of a new message on her phone partially called her back to reality. Choosing to ignore that distraction, Michelle kept strumming her nectar-squishy clit and pushed her big round bubble-butt back against her panting brother's groin, matching his relentless rump-cramming strokes in an attempt to feel his horsecock push impossibly deeper inside her already cum-coated bowels and thus empower her next assgasm even more. Only after her rippling, shaft-massaging anal walls had finally milked another rectum-hosing ejaculation from Tyler's stiff dickmeat and the storm of pleasure that was crashing over her finally abated a little did Michelle once again acknowledge the annoyingly persistent humming and vibrating of her phone.

Drowsy with his afterglow and busy peppering her smooth neck with butterfly kisses as he let his huge, fully buried schlong soak in the creamy heat and tightness of her forbidden chute while her twitching little asshole squeezed the very last dollops of his load from him, Tyler eventually murmured: "You should probably get that. Who's texting you this late anyway?"

"Probably Gabby," Michelle replied, letting out a half-sigh and half-purr that made Tyler chuckle, because it synthesized in one soft sexy sound how her slight irritation at being interrupted right at that moment still couldn't prevail over the all-encompassing, deliciously sinful pleasure she was enjoying and sharing with him as his meaty boner stretched her needy butthole out and filled her doubly creampied rectum to the brim.

"She said she had some sort of big family reunion kinda thing going on, with people staying over at her house too," Michelle languidly went on, wiggling her deeply impaled booty against Tyler while he tightened his bear hug around her petite frame and filled his palms to overflowing with her big round tits. "But she also told me to wait for some 'good stuff later', so I guess that's that..."

As soon as she reached for her phone in the pile of her hastily discarded clothes by the bed and glanced at the screen, Michelle's residual annoyance evaporated completely to make room for a cascade of naughty giggles. "Yep! That's Gabby alright!"

Turning her cell toward Tyler so that they could both see the screen, Michelle played the video that their friend had sent them. Immediately, it was obvious that the clip wasn't particularly polished in the way that the vast majority of the double anal videos Gabby had given them tended to be, but the spontaneous nature and raw feel of the scene made up for the lack of editing.

Caught in a POV style, the video opened on Gabby on her knees jacking off two fat dicks which she alternatingly took deep into her mouth and sucked on with lewd gusto. Based on their knowledge of Gabby's personal stash of incestuous homemade porn, not to mention the live show they had happened to catch the night of the graduation party, Michelle and Tyler easily identified the two guys that Gabby was voraciously blowing as her cousins, Eddie and Rob, one of whom must have been holding the phone and filming the whole thing. Hot as it surely was to watch Gabby gobble down one of her horny cousins' hard dick while she jacked off the other's saliva-slick shaft with her manicured hand, the really thrilling part of the video began about a couple of minutes in, when the mewling brunette opened her mouth wide and forcibly crammed both of those stiff slabs of cockmeat into her oral cavity.

"Whoa! That's a new one!" Michelle gasped with excitement, cooing immediately afterward as she felt Tyler's butt-stretching monstercock flex deep inside her seed-flooded anal sheath. "I don't think she ever did anything like that before, right?"

"If she did it wasn't in any of the videos she gave us," Tyler replied, cupping Michelle's massive boobs more firmly and pressing his groin harder against her soft pillowy asscheeks, jamming his fully buried sausage as deep as possible inside her creamy anal passage.

All the while, on screen Gabby was gagging and spluttering and slobbering all over her cousins' veiny rods, trying to force them both all the way down her overstuffed throat at the same time. The sight of her spittle-dribbling, indecently dilated lips stretching out to the limit around Eddie and Rob's dongs made the siblings moan with horniness, causing Michelle to resume strumming her clit while Tyler began gently humping into her gloriously plump booty, stirring her buttery bowels with his enormous pole. Despite her valiant efforts though, Gabby didn't seem to be able to fit more than half of the twins' shafts down her impossibly crammed gullet, but the look of unquenchable lust she cast right into the camera and the glint of scorching hot desire burning in her dark, half-closed eyes was more than enough to ensure Michelle and Tyler that, sooner or later, the brunette was somehow going to learn how to take those two huge dicks inside her mouth just as easily as she could already take them up her ass. For the time being though, Gabby seemed content to settle for a sloppy, slobbering double-facefucking session, which she immediately set about accomplishing by bobbing her raven-haired head back and forth on Eddie and Rob's truncheons, jamming her overfilled oral cavity with half of their schlongs at the same time over and over again.

Already turned on like crazy by Gabby's obscene dicksucking antics, Michelle and Tyler were thrilled to realized that the brunette's cousins appeared to be genuinely surprised by her attempted at double oral penetration, as their panting voices testified in the video.

"Holy shit, prima! What's gotten into you tonight?! This is fucking hot as fuck!"

"For real, you're such a sexy slut, Gabs! Just go easy on the moaning and gagging, or they're gonna hear us."

That last comment made Michelle and Tyler's equally transfixed eyes bug out as they realized that, just a few feet away from the incestuous trio and past some kind of garden bush or flower bed, a big French window was visible behind which the shadows of people inside the house were vaguely discernible as they passed by every once in a while. That detail, along with the fact that Gabby seemed to be wearing a fancy formal dress that showcased her perky tits in a tastefully naughty way, convinced the siblings that the brunette and her big-dicked cousins must have sneaked out of some ongoing family event to have sex in a not-so-hidden corner of the garden! The enhanced eroticism provided by that risky context multiplied the already crazy high level of hotness of the reckless, spittle-filled double blowjob they were watching, making Michelle and Tyler breathe heavily as her fingers danced faster on her clit and his huge ass-stuffing boner began pumping harder in and out of her tight, cum-lubed asshole.
