*****

As he groggily emerged from deep refreshing sleep into foggy consciousness, Tyler basked in a sense of warm delight pervading his supine body and centered around his thick morning wood.

Pleasant memories and afterimages from the previous night lingered in Tyler's mind as he attempted to open his eyes, images of his sister's sweet mouth wrapped around his huge boner as she blew him to the fourth and final bursting ejaculation of the night's ass-centric fuckfest. The rush of endorphins that had hit Tyler as he flooded Mimi's dick-nursing oral cavity with cum and the delicious swallowing noises she had made as she voraciously gobbled down his potent seed were the last things the teenager remembered before his curvy little sis had cuddled up in his arms and they had fallen asleep together, locked in a loving embrace.

Now, dazed and more than half asleep as he was, Tyler conflated the pleasure radiating from his rigid pole with the echoes of that ball-draining goodnight blowjob he had received from Michelle before they had drifted off in his bed, but as soon as his heavy eyelids managed to blink open just a little bit, he realized that things were in fact even better than he imagined.

Straddling his lap in a reverse cowgirl position, with a dainty hand holding onto his huge shaft so that it was nestled cozily between her pillowy buttcheeks while his fat glans was pressed against her pink, lewdly pulsating little hineyhole, Michelle was carefully lowering her big round booty down on Tyler's imposing erection. The sight of his sister's plump asscheeks hotdogging his veiny schlong was just as amazing as the feel of those two soft fleshy buns smothering his boner, and the obscenely erotic vision of her miniature butthole slowly but surely dilating around his bloated cockhead was the perfect addition to the suckling, gently nibbling feel of her rosy pucker gradually opening up to accept his mushroom tip.

The shiny layer of lube coating both his dong and her docile, ever cock-hungry asshole left no doubt in Tyler's mind that Michelle had greased them both up nicely while he was still sound asleep, a fact that further reiterated how awesome his sister was and how genuinely devoted she had become to their shared passion for anal sex. A warm and fuzzy whirl of affection washed over Tyler as he realized that Michelle must have decided to wake him up by impaling her beautiful ass on his boner as a way to reciprocate the thorough pussy-licking and butthole-rimming he had given her the previous morning; the fact that a proverbial sleepyhead like Michelle had woken up before him just to do that brought a big goofy smile to Tyler's face, further strengthening his deep love for his sweet little sis.

An irrepressible groan erupted from Tyler's mouth in perfect sync with the sexy squeal that escaped Michelle's lips the moment her gummy pink sphincter relaxed and widened enough to let his purple knob pop entirely past her butt-ring and slip into her exquisite anus. The warmth, softness and tightness of his sister's heavenly asshole shocked Tyler into full wakefulness, stirring his arms into motion so quickly that, before a whimpering Michelle could lower her bouncy bubble-butt more than a couple of inches down his massive dong, Tyler's hands were already planted on her fabulous asscheeks, kneading and caressing and massaging away at her perfect cushiony globes.

Gasping in surprise as much as in delight, still lustfully determined to sit on her brother's enormous schlong and force every last sphincter-stretching inch of his dickmeat into her tiny bootyhole, Michelle looked over her shoulder as soon as she felt Tyler's fingers sink into the soft, jiggly flesh of her plump rump. Framed by long sleep-tousled locks of her light brown hair, Michelle's delicate features looked even cuter than usual to Tyler as she scrunched her lips in a silly pout that seemed particularly comical given that, all the while, she just couldn't stop mewling from the mix of strain and pleasure that was pervading her petite curvy frame as she stubbornly set about the task of gobbling his fat boner into her small anus.

"Aw balls, you're awake..." Michelle sighed while eagerly continuing her butt-stretching descent on Tyler's veiny pole. "I wanted to uhhh fuck... I wanted to have you all the way up my ass before you oowwhh... Before you woke up. Oohh god, Ty, you're so fucking big... Actually I'm kinda glad I don't have to uuhh... To keep quiet anymore. Uhhh fuck yesss!" Michelle giggled and moaned at the same time as she winked at her smiling brother, biting her lower lip while her overdilated bootyhole kept stretching out and sliding down along his humongous truncheon, half of which was already engulfed inside her warm, divinely snug chute.

Chuckling and drinking in the way his beautiful little sister's eyelids fluttered closed as her mouth went slack from the sheer mind-melting delight of letting her velvety soft anal walls get widened and crammed full of his dickmeat, Tyler rose an eyebrow and replied: "You seriously thought I could sleep through this?! Come on, Mimi, your ass feels way too good, of course I'm gonna notice it when it's wrapped around my cock! But it's an awesome way to wake up all the same..."

"I know, right!" Michelle laughed along with her studly big brother even as her breathing grew more ragged and her anal passage more and more stuffed with his enormous schlong. "I thought you'd like it and ahhh fuck... I loved the way you woke me up yesterday. That was really nice... Uuh god, my ass is sooo full of cock!" Michelle murmured with a heartwarming smile before continuing: "Plus I figured uuhh... I figured we wouldn't have much time later today with oohh fuck... With Mom being home for the graduation ceremony. And then there's Gabby's party later, so... Ooowh my fucking god! You're so fucking deep in my ass, Ty!" Michelle panted with debauched joy as her tautly stretched butt-ring finally ended its downward gliding descent and wrapped itself around the broad root of her brother's massive schlong, engulfing him from tip to base inside the tight, rippling warmth of her needy anal passage.

Grunting from the dick-smothering pleasure that her steamy, velvety soft rectum was giving him as it adapted to his ass-stretching presence, Tyler shook his hazy head in an attempt to focus and recall all the events waiting for him and his sister in the day ahead.

"Fuck, that's right! Stupid graduation... And that party at Gabby's house too, yeah... And Mom's home from work today!"

"Yeah, that's right: she's home. So try not to ooohh... Try no to be too loud, okay?" Michelle instructed her brother with a naughty wink as she started gently rocking her majestic, fully impaled booty on his lap, stirring her cozy rear passage with his enormous hardness as her smooth, dick-caressing anal walls adjusted to being widened to their limit by his throbbing, orgasm-inducing monstercock.

Smirking as he noticed the telltale motions of Michelle's right shoulder and arm indicating that her fingers must be quite busy rubbing away on her dewy little pussy, Tyler reluctantly let go of his sister's fabulously plump buttcheeks and ran his hands up along her flaring hips, her narrow waist and reached up to her front, until his palms made contact with the hefty, fleshy roundness of her big juicy tits. As soon as his digits started tweaking her puffy nipples, Michelle couldn't help but let her hushed moans spike up in volume, making Tyler chuckle teasingly.

"Hey, keep it down, Mimi! Mom's home, remember?"

Scoffing and shaking her huge melons side to side until her sensitive nipples were free of her brother's tormentingly delightful fingertips, Michelle cast Tyler a playfully reproachful glance as she exhaled in anal ecstasy.

"It's hard enough to be quiet with your horsecock up my butt, Ty, so leave my tits alone for now, jeez! Just relax and let me do all the work, okay?" Michelle concluded with a giggle and a gasp of ass-centric delight as she raised her dick-skewered booty a few inches and then let it fall down on Tyler's monumental erection again, cramming his veiny truncheon to the hilt inside her asshole once more. "Ooh fuck, Ty! That's so fucking good! Uuhhh god..."

Smiling and nodding, Tyler agreeably let go of his sister's ample boobs to plant his hands back on the big meaty globes of her bubble-butt and resume kneading those superbly round asscheeks while, panting and mewling as quietly as she could with his gigantic pole jammed into her twitching little anus, Michelle began eagerly working her epic ass on his cock.

Keeping a good half of his mighty shaft always embedded inside her suctioning anal tunnel, Michelle bounced her juicy booty up and down on her brother's dickmeat with careful but persistent self-impaling motions, coaxing deep groans from Tyler's throat and barely muffled squeals of ecstasy from her own mouth. Shaking her big round rump for Tyler's visual pleasure as her overdilated bootyhole slid fluidly along his rock-hard truncheon, Michelle got into a slow sensuous dick-riding rhythm that made both of them transition into that newly found state of shared anal bliss and mutual completion which neither of them ever imagined would even exist, but which now they both ached to reach any time they possibly could.

Soon enough, as Michelle's reverse cowgirl ride got faster and wilder and her epic booty started seriously bouncing away on Tyler's rampant horsecock, the siblings couldn't help but vocalize more than just indistinct moans of delight. Their love and passion for each other and their disbelieving joy of getting so much pleasure and closeness from anal sex simply needed to surge out and be expressed, even if just in panting, hushed tones.

"Oohh Ty... Uuhh fuck, yesss, Ty! Oowwhh I love your big cock so much... You fill me like crazy, you get sooo deep inside me! Uuhh your cock is so perfect, so deep in my aaaass!"

"I love your ass Mimi! Holy shit, it's amazing... Your asshole is so hot and tight! And look at this big round ass, oh my god! So thick and juicy! Oohh I love it, Mimi, aaahh Mimiiiii!"

By the time they heard the sound of their mother's bedroom door opening and closing down the hall followed by the distant pattering of the shower running in the master bathroom, Michelle and Tyler's goodmorning buttfuck had already reached its climax and the siblings were lying in a tight spooning position, cuddling and panting and savoring their afterglow.

With his chubby schlong still jammed balls-deep inside her cum-flooded rectum and his powerful arms wrapped around her soft curvy body, Michelle sighed and wiggled her plump booty back into Tyler's groin, squeezing her creamy anal walls around his fat boner, lazily and sexily calling his attention to the fact that their morning fun was over and they should get ready before their mother got out of the shower. In response to his sister's dick-caressing anal squeezes, Tyler just groaned and tightened his embrace, pawing her huge boobs in his hands and nuzzling her neck, peppering her smooth skin with tender kisses. Beaming with joy and yet trying to stifle her giggles, Michelle countered her brother's smooching assault by turning her head toward him and planting her tumid lips on his mouth, leading him to share a deep loving soulkiss.

When their mouths finally broke apart, Tyler's huge cock remained cozily tucked inside Michelle's snug little bootyhole and his crotch stayed pressed urgently against the soft, pillowy globes of her asscheeks. The siblings didn't need words as their gazes locked and focused deeply onto one another's being. While Michelle and Tyler shared a peaceful moment of silence, their eyes communicated something else beside their intense love for each other: it was time for them to get out of bed and prepare for their graduation day.

*****

Less than a week had passed since the amazing night when the siblings had first had sex together, and since then their relationship had grown stronger and more nourishing than ever before. In truth, Michelle's gift of her anal cherry to Tyler had opened up a new, deeper and more intimate level in their lifelong bond. Even though they had always been warm and affectionate with each other, Michelle and Tyler were blown away by how intensely connected and close they felt now that they were able to express their love in a physical way through their frequent and mutually satisfying anal couplings. Indeed, beside feeling perfectly natural, having buttsex turned out to be a ton of fun for them both.

After their first life-changing assfuck, Michelle and Tyler were very much determined to spend every single moment of their time together having sex, and, whenever they were home and their mother wasn't around, they enthusiastically did so. The fact that he now had full access to his beloved sister's epic bubble-butt, and was not only allowed but actively encouraged by her to plunge his huge cock into her sweet little asshole, was such a phenomenal turn on for Tyler that he was in a constant state of semi-hardness at the very least. In turn, Michelle loved how enamored her hunky brother was with her big round booty and couldn't get enough of all the attentions he lavished on her plump ass all the time. Tyler's adoring compliments and butt-kneading caresses and the permanent bulge in his crotch made her feel the sexiest, most beautiful and desirable girl in the world, and Michelle simply couldn't get enough of that empowering sense of being truly, unconditionally and exclusively loved.

Beside that intense emotional satisfaction, Michelle got also very quickly and very deeply addicted the toe-curling feel of having her brother's humongous schlong sliding deep, deep into her ass and filling her tightest and most sensitive hole to absolute bursting as he sodomized her with all of his passion, until a deluge of his dense cum exploded from his fat spongy glans and flooded her rippling rectum, further enhancing her lewd anal ecstasy. The screaming, gushing orgasms that Tyler could gift her by fucking her docile bootyhole were genuinely shocking to Michelle, in the most positive sense of the word. Her toe-curling assgasms filled her with such a unique sense of full-body pleasure that Michelle was certain she could never stop craving it and seeking it from her brother, much like she would never stop relying on his reassuring presence and sincere love to feel truly safe and happy.

Seamlessly and effortlessly, the siblings incorporated oral and anal sex into their day to day life as if it was the most normal thing for them to do, which was exactly how it felt. Getting on all fours and presenting her big bouncy rump to her brother to have her needy butthole stretched out and pumped full of warm seed, or pulling down his pants to gobble his enormous sausage into her throat and suck him off until he hosed her mouth and face and jutting tits with thick, creamy ropes of his delicious sperm became normal and instinctive acts for Michelle. In the same way, kneeling behind his sister's heart-shaped booty and peeling down her ass-hugging shorts to worship her lovely pink rosebud with smooches and tongue swipes as his fingers took care of her clit and pussy until she reached her gushing climax became commonplace occurrences for Tyler as well.

Overjoyed and hyper horny all the time, the siblings had never been happier to have the house to themselves for the better part of the day, and they took full advantage of their mother's absence by having sex all over the place. The only downside of their newly discovered sexual intimacy was the fact that they now had an even harder time than usual keeping their hands off each other when Ellie came home. Still, tough as it was to resist the need to jump each other's bones with their mom around, Michelle and Tyler still managed to rein in their urges when it was absolutely necessary to do so. In fact, all the efforts they had to put into behaving themselves in front of Ellie in the evening fueled their burning passion and urgency even more, so that when they were finally together again behind the safety of his or her bedroom door, Michelle and Tyler were even hornier for each other and took even more satisfaction in their nightly anal fuckfests.

Given how used they had got in the previous days to capitalize on their mom's merciless work schedule to have sex whenever and wherever they wanted, Michelle and Tyler couldn't help but be impacted by how starkly different from their usual routines their graduation day turned out to be.

The fact that Ellie had taken a day off work was an event in and of itself, and as glad as the siblings were to see how important it was for their mom to witness their graduation from high school, they couldn't help but get very antsy when they fully realized that, with her around all day, it would be impossible for them to swim naked in the pool and then have buttsex on the recliners, or to sixty-nine on the couch when they got bored of a TV show, or to do all the other naughty things they had been doing lately all the time. It did help that Michelle had woken Tyler up by stuffing her needy little asshole with his meaty pole, giving them both an early morning fix of anal pleasure that would help them endure the forced abstinence of that special day, but it still was pretty rough on them.

Despite her newly discovered and barely manageable need to feel her brother's huge cock up her ass as frequently as possible, Michelle had an easier time than Tyler when it came to actually dealing with the day's unavoidable ban on buttsex. Having crammed her favorite plug up her bootyhole before breakfast with the intention of not removing it until she could replace it with Tyler's fat sausage, Michelle kept herself anally teased all through their graduation day. With her twitching, sensitive anus persistently stimulated by the sphincter-stretching toy, Michelle was more or less on the verge of climax all the time; she only had to slip her hand into her panties and give her engorged clit a few rubs to bring her moist pussy to a quick pressure-venting climax, and she did so at any chance she got.

Of course, the downside of having her hineyhole teased non stop by the buttplug was that she was constantly reminded of how insanely more awesome it would be to be actually fucked in the ass by the brother's massive dickmeat instead, but being buzzed with arousal and being capable to bring herself off almost any time she liked was a good enough tradeoff for Michelle. Tyler, on the other hand, didn't have it quite so easy.

The sight of sister's beautiful bubble-butt was as tormenting as it was magnificent, causing his pants-trapped boner to be achingly erect all the time with no prospect of imminent, or at least adequate, release. All too aware of the frequent sneaky climaxes that Michelle gave herself, Tyler could only grit his teeth in frustration as he strove to keep his bulge concealed, groaning longingly whenever his giggling sister extended her nectar-wet fingers his way right after she had diddled herself to orgasm, allowing him to sniff her sweet girlcum and, if their mother wasn't looking, even lick her precious juices off her fingertips as well. Sure, Tyler did retire to the bathroom to quickly jerk off a couple of times throughout the day, but that was far from enough to sate his raging lust for his little sis's fabulously plump ass.
