Little Sister's Big Butt Ch. 08

Tyler and Gabby's laughter resounded in the room as Michelle, still dazed and far from fully recuperated after her crazy orgasmic high, barely managed to sit up before she got dizzy and had to let herself fall on her back again, her huge tits all the while swaying all over the place as she groaned and finally rested sprawled on her back, laughing.

"Okay, maybe I'll just lie down a little bit longer!" Michelle exhaled, looking at Gabby and Tyler in turn, smiling at them. "But there's no way I'm missing this! God, it's so exciting! You two are gonna have so much fun, I promise you. I mean, I should know, I fuck you both all the time!"

To the sound of their collective chuckles, Michelle slowly rolled and shifted and repositioned until she was lying on her back beside Gabby, her head by the brunette's thighs. Without needing to be prompted, Gabby understood what Michelle had in mind, so the two of them deftly got in a sixty-nine position, granting Michelle a front row seat underneath Gabby's groin.

"Yeah, this is much better!" Michelle giggled as she looked up and drank in the sight of her friend's juice-glazed pussy and dilated, waiting-to-be-plugged asshole.

The large purple knob of her brother's cockhead was poised right outside of Gabby's wanton orifice, and Michelle couldn't help but lick her lips at that image, but then her gaze swiftly moved past Tyler's menacingly big dong to focus on his handsome face. As soon as their eyes met, Michelle's smile became warmer and brighter and broader.

"Go ahead, Ty," she said, winking at her brother, "you've left her waiting waaaay too long already!"

"Yeah, you sure did!" Gabby agreed with a snicker that triggered Michelle's silvery giggles as well.

Grinning, still looking down at his adored little sister's cute face, Tyler nodded as he felt his heart swell with inexpressible joy. All he could say while he breathed in and out and tried to get a grip on the thrumming maelstrom of love and lust raging inside him was: "I love you, Mimi."

"I love you too, Ty," Michelle replied, her sparkling green eyes all shiny with emotion and arousal.

"Yeah, yeah... Alright, so you two love each other, and I love you both, and you both love me back, yadda yadda yadda..." Gabby cut in, exhaling theatrically, her teasingly playful tone very much tinged with impatience and horniness. "Now, can we get on with the fucking, please?"

"Absolutely," Tyler chuckled, glancing at Gabby's intense dark eyes for a moment, only to then once again return to ogling her sweet round ass, which she kept wagging gently side to side, making her perfect globes jiggle enticingly.

In truth, even though Tyler had already found the ass of his dreams in his sister's big, juicy and beautifully plump booty, there was no denying that Gabby's shapely rump was a very close second in his personal list of best asses ever. Lusciously full yet toned and firm, the brunette's tanned bubble-butt protruded gorgeously from her back, and the swelling curve of Gabby's hips was so perfectly complementary to her thin waist that Tyler was sure there must be some kind of magical hips-to-waist ratio behind the formula for the perfect ass, or something along those lines. At the end of the day though, what really mattered was that, by luck or fate or whatever other inscrutable reason, he had ended up being gifted not just his sister's fabulous ass, but now Gabby's too, and that was a blessing that Tyler was very happy about and thankful for.

Grinning and salivating as he stared at the brunette's gaping anus, which was still desperately winking at him even though it was now way less distended than before, Tyler shook himself out of his butt-staring trance and grabbed his achingly hard pole at the base, lining it up perfectly to penetrate Gabby's wanton orifice. Just as he was pressing his large glans against the brunette's eager bootyhole though, a sudden thought struck him.

"Wait! The lube!"

"Jesus, Ty!" Gabby groaned in frustration, unable to play it cool anymore, such was her visceral need to finally try out for herself the horsecock that always made Michelle cum like crazy. "You're really torturing me here! Who cares about the stupid lube, just ram it in! I'll be fine, don't worry. I mean, I can even take two dicks in my ass, remember?"

"Of course I remember!" Tyler grinned back at Gabby, actually liking the way she was getting all antsy and needy as she looked back at him with devouring desire painted all over her perfect features. "I just thought that maybe..."

"Here you go! All good!" Michelle cut in with a giggle, meanwhile squirting a nice dribble of lube straight into Gabby's twitching sphincter and another one on her hand, which she promptly wrapped around her brother's girthy shaft. As she started stroking Tyler's nectar-slick dong, thus further coating it with the slippery fluid, Michelle said in mock-resignation: "I guess I'll just have to do the honors, or we'll never get this done..."

As Gabby sighed in languid approval and Tyler chuckled looking down at his sister in desire-addled adoration, Michelle's schlong-tugging hand pulled his poised horsecock just another inch closer, guiding his precum-leaking tip right into the pulsating opening of Gabby's horny butt-ring. Aided by the lube and by the prepping that the brunette had done with Michelle earlier, not to mention her consummated talents in all things anal and double anal, Gabby's asshole accepted Tyler's broad cockhead with obscene ease. Dilating docilely and opening up with barely any effort despite his humongous size, Gabby's gummy little orifice allowed Tyler's huge rod to slide into her ass without strain, engulfing his whole glans in the heat and snugness of her cozy chute in the blink of an eye. Seeing her brother's fat mushroom head being gobbled up by her friend's needy bootyhole just like that made Michelle gasps and giggle and pause her shaft-stroking manipulations, thus stopping the butt-impaling motion that her hand had imposed on her brother's monstercock.

"Hey, don't stop now!" Gabby immediately complained at that, dipping her head down to give Michelle's drenched slit a quick lapping tongue-swipe just to call her back to her duties. At that point though, much to the brunette's delight, Tyler was more than ready to take charge.

Growling deep in his throat as he savored for the first time the soft warmth of Gabby's exquisite anus around his broad glans, Tyler planted his hands on the brunette's gorgeous buttcheeks and spread them nice and wide while giving a firm push with his hips, driving his dong forward and thus feeding more of his veiny truncheon into her greedy ass. Unsurprisingly, Gabby's reaction to the feel of Tyler's horsecock sliding deeper into her receptive anal tunnel was immediate and very enthusiastic.

"Uuhh yes, yeaah, stud, that's it... That's what I'm fucking talking about..." Gabby mewled, tossing her head back and causing her long, jet-black locks to cascade over her arched back, her whole demeanor getting languid and mellow as more and more girthy inches of stiff cockmeat entered her narrow chute. "Uunngh fuck yeah! So fucking good... Oowwhh fuck!"

Entranced by the image of Gabby's elastic asshole smoothly accepting more and more of his dick, and further aroused by the sight and feel of his sister's dainty hand pumping his exposed length and coating it with lube, Tyler groaned with delight at the feel of the brunette's silky soft anal walls adjusting around the embedded portion of his schlong. As he immersed himself deeper and deeper inside Gabby's asshole, he was stunned to feel almost no resistance around his invading boner except for the natural snugness of her velvety forbidden passage. No signs of seizing or cramping came from her anal muscles, which simply relaxed and let him glide further up her ass, while the walls of her tight rectum seemed to be molding and reshaping instantly to fit his massive schlong as he delved deeper and deeper into her steamy bowels.

Indeed, Tyler's booty-skewering progress was so fluid and swift that, within seconds of his glans disappearing into Gabby's butthole soon followed by his shaft, Michelle had to stop lathering his pole with lube and let go of it, so that he could cram the final veiny inches into the brunette's anus. For an instant, Michelle was kind of sad that she couldn't touch and masturbate Tyler's cockmeat any more, but the next moment she was looking up in awestruck admiration, her eyes wide and her jaw slack even as her lips curled in a naughty smile brought on by the epic spectacle of Gabby's overdilated butt-ring wrapping itself tautly around the very base of Tyler's humongous boner.

"Uuungh yes, fuck yes!" Gabby exhaled, letting out a husky laugh that was very close to a breathless gasp as she savored the rectum-cramming hugeness of Tyler's horsecock totally filling her needy asshole. "Mmmh so fucking big... Congrats, stud! You feel almost as big as two regular dicks up there! Ooohhh shit, you're so fucking deep... My ass feels so fucking full, oh my god... Uunggh yes... This is awesome! Remind me again why the hell we waited so long to do this?!"

As Gabby moaned and hummed in anal delight, Tyler and Michelle shared a chuckle at her remark. Dazed by the deliciously naughty feel of tight, soft dick-encasing warmth that Gabby's clingy passage was gifting him and thrilled by the realization that he was sampling another fabulous ass beside his sister's, Tyler was about to come up with a reply to the cheeky brunette's quips, but before he could form any actual words, a deep lustful grunt escaped his lips as Gabby started bouncing her skewered booty back against him, rocking back and forth with wanton eagerness and thus buttfucking herself on his humongous rod, multiplying his delight with the silky, slippery friction of her narrow tunnel massaging his fat, throbbing hard boner.

"Ooh fuck, Gabby! Ooooh fuck yeeahh!" Tyler growled even as the initial rush of pleasure of feeling Gabby's asshole gliding back and forth along his dong became ten times greater, due to the fact that she also began rhythmically squeezing her anal walls around him too. "Holy shit! Fuck, Gabby!"

"Yeah, I know!" the brunette just replied, her voice sultry with slutty pride yet trembling as she attempted to demonstrate her anal queen status on a dick as enormous as Tyler's. In truth, the real challenge for Gabby was not just Tyler's sheer size, but the fact that, exactly due to the length and thickness of his monstercock, she was already feeling all tingly with preorgasmic joy: she just loved so much the way he filled and stretched her needy asshole. Still, she couldn't resist the chance to be playful and tease him a bit more. "Feel free to start fucking me back, stud! Uungh... Whenever you're ready..."

A peal of bright laughter from Michelle fused with Gabby's panting chuckles. "Wow, Ty! I think that was a challenge, or something..." Michelle said, arching her eyebrow as she looked up into her brother's lust-distorted face, the vision of Gabby's curvy bubble-butt slapping back against his groin and her overstretched asshole gobbling up his whole schlong over and over creating an almost irresistible distraction all the while. "Actually, I'm sure it was a challenge. You're such a tease, Gabs!"

Whether or not Gabby was going to respond, only a stream of gasping mewls erupted from her mouth, because Michelle's lips immediately glued themselves to her dripping pussy and she started licking and slurping away, preventing the brunette to focus enough to speak. The sudden tidal waves of pleasure radiating from her pussy had an instant effect on Gabby, causing her to slow down her self-impaling tempo, but still she didn't entirely stop bouncing her ass back into Tyler's horsecock. Indeed, even though she could only squeal and mewl, her playful yet wanton defiance remained, conveyed now by the sultry over-the-shoulder looks she cast Tyler.

The smoldering lust burning in Gabby's dark eyes was the clearest confirmation that, as Michelle suggested, the brunette was indeed challenging him, in a sense. And of course, since it was a buttfucking challenge, Tyler couldn't help but be all in. That, plus the sight of his sister's mouth locked in a lewd French kiss with Gabby's pussy and the sounds of Michelle's slit-nursing assault mingling with the brunette's irrepressible moans of pleasure, brought a grin of deep, lustful excitement to Tyler's lips, spurring him into action.

"Okay, Gabby," he chuckled as he grabbed onto her taut round asscheeks, pawing them possessively. "Challenge accepted!"

And with that, Tyler began bucking his hips, driving his achingly hard boner deep into Gabby's needy bootyhole. At first, he didn't force his pace but instead chose to match the brunette's steady bouncing rhythm stroke for stroke, so that he slid almost all the way out of her tight anal sheath when she bounced off his groin, only to then drill his dong balls-deep into her eager anus right as she pushed back into him, thus causing his rectum-jamming plunges to be particularly swift and intense, much to his own and Gabby's pleasure.

Indeed, already thrown off by Michelle's pussy-eating attentions, Gabby found herself moaning deliriously the instant Tyler's began actively humping her ass. As she immediately noticed, it was one thing to use his giant schlong as a static fuckstick, but when that fat, veiny, throbbing hard slab of dickmeat began unleashing its rump-splitting power, things changed radically. A quick stabbing orgasm hit Gabby's slender frame in a matter of seconds as she and Tyler seamlessly matched rhythms, his long, fluid balls-deep thrusts triggering a big burst of anal bliss that was multiplied in intensity by the voracity with which Michelle's lips and tongue took care of the brunette's drenched pussy.

Unsurprisingly, the gushing rivulets of girlcum that inundated Michelle's mouth only motivated her to redouble her slit-slurping efforts, while at the same time the feel of Gabby's overstretched asshole pulsing in climax as it glided along his shaft while her anal walls rippled with orgasmic joy around his girth egged Tyler on, causing him to pick up the pace.

"Uungghh fuck! Oowwhh shiiit! Uuuunhhh... So fucking good!" Gabby squealed, her head thrown back as she screamed out and shivered in ecstasy, all the while still rocking in place to meet Tyler's booty-plowing thrusts.

As sweetly climax-addled and dizzy as she was, Gabby was still managing not only to slap her ass back against Tyler, but, most impressively to him, she wasn't missing a beat as far as working her anal muscles around his pistoning boner was concerned. Even as she came and writhed and tossed her raven mane across her shoulders, the velvety smooth walls of Gabby's dick-packed rectum continued obeying her wanton will to prove herself a true anal queen to Tyler, much to his joy. The deep milking squeezes and potent tugging spasms animating the brunette's narrow chute felt amazing, especially because they were combined with the delicious pressure and friction that came from the mere act of fucking her tight asshole. Indeed, Tyler would have complimented Gabby on the way she could control her anal muscles so flawlessly even in the throes of climax, but, in the spirit of the naughty competition she herself had instigated, he decided to save it for later, choosing instead to just keep plunging his enormous truncheon balls-deep into her steamy anus over and over again.

"Fuck... Oohh fuck, guys!" Gabby finally exhaled once her stabbing orgasm started winding down. Her arms were shaking and her fingers were clawing at the sheets as the last jolts of pleasure still coursed through her lithe body, whose back and forth self-impaling rocking motions she was now striving to maintain. "Uunggh... You two are so fucking good together... Mmhh yeah, you're making both my holes cum so hard!"

Since she was still hungrily munching on Gabby's gushing slit and had no intention of stopping just so she could properly talk, Michelle's response came out as a mere jumble of slurping, squishy pussy-muffled sounds, while Tyler's only answer was the big grin he flashed Gabby as he continued vigorously pummeling her flawless bubble-butt. Slamming her juicy ass back into Tyler's body at the same pace of his increasingly faster thrusts, Gabby was panting and sweating and looking ever wilder and pleasure-drunk, even though she was still managing to keep up somehow. However, what was most striking to Tyler was the fact that the brunette's lewd playfulness seemed to only have been stoked further by her unexpectedly quick and intense climax.

"Mmh, Ty, your huge dick feels so good in my asshole..." Gabby purred breathlessly, engulfed as she was by the clit-centered shock waves of bliss that Michelle was gifting her on top of the constant tremors of deep, body-wracking anal pleasure rumbling outward non-stop from her overstuffed rectum, which Tyler kept drilling with relentless force. And yet, she just couldn't stop herself from raising the bar even more. "Uuhh fuck yeahh... Your monstercock is stretching me so fucking much! Come on, stud, fuck my ass harder... Make me squirt again, let's give your sister more pussy juices to drink!"

Chuckling and shrugging his broad shoulders as he looked into Gabby's lust-glazed eyes, Tyler simply said: "Sure, if you want it harder, I'll fuck you harder. No problem, Gabs." Glancing down between Gabby's thighs, Tyler managed to lock gazes with his sister just long enough to joke: "Get ready, Mimi, here comes another mouthful of pussy juice!"

Again, Michelle's words were made unintelligible by her stubborn devotion to her slit-munching duties, but somehow Tyler was sure that her answer must be positive and enthusiastic. And so, without wasting a second, he accelerated his rump-riding cadence even more.

And this time, despite having handled herself like the true anal queen that she was, Gabby started showing signs of having possibly bitten off more than she could chew.

At first, as Tyler's sodomizing tempo grew seriously frenzied and his huge boner began flying in and out of her ass so hard and so fast that his motions became a blur and the impacts of his groin slapping against her round asscheeks became loud enough to completely mute out Michelle's sloppy pussy-eating slurps, Gabby more or less managed to keep up. Her control over her anal muscles was still there, meaning that she could still wantonly squeeze Tyler's dong from tip to root in the warm, rippling grip of her slick rectum on his out-strokes while relaxing completely to facilitate his jarring, balls-deep in-strokes. But that was all that she could still do.

Gone were the sexy undulating bounces with which she had so far pushed herself back into Tyler's crotch, gobbling his horsecock into her insatiable asshole; now the brunette was totally limp while being buttfucked, and only the fact that Tyler's big, powerful hands were holding her by the hips and slamming her lithe body back and forth to meet his booty-plundering thrusts still might have given the illusion that Gabby was moving with him, while in truth she was being moved by him. Arching her back and keeping her arms extended underneath her with her palms firmly planted on the bed was the limit of the control that Gabby still had on her pleasure-ravaged frame, and even that final semblance of self-mastery was teetering on the brink of total orgasm-induced annihilation.

Delirious with such anal bliss as she had never experienced before, caught in a sizzling chain of back-to-back ass-centric shock waves whose intensity was made even greater by Michelle's clit-suckling contributions, Gabby could no longer tease or joke. In fact, she could not even speak actual words at all. Her mouth was only capable of breathing raggedly and producing gasps and mewls of wanton satisfaction at being anally owned by the biggest, hardest, thickest cock she had ever taken.
