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.
