Stiff as a marble column and just as imposing, Tyler's boner looked positively ready to explode. It pulsated and flexed incessantly, like a rabid savage beast straining inside its cage. His humongous pole was so thick and overswollen, even by its usual mammoth standards, that Gabby got worried for a moment and wondered if Tyler was okay or if he actually needed medical help or something. The angry purplish red color of his bloated precum-drooling glans further added to the impression of powerful manliness that his formidable erections always conveyed, and particularly so at that moment. Taking in the slick sheen of pre-ejaculatory fluid coating the whole shaft from tip to root, focusing her gaze to follow a clear drop of runny precum as it trickled down his considerable length, Gabby decided that no, Tyler probably wasn't exactly glad about the situation, but his discomfort was most likely tied to his desperately contained desire and his unfathomable albeit restrained horniness. Yeah, Gabby concluded mentally, rather than medical attention that massively hard cock needed the relief of a big orgasmic burst of pleasure. And what a burst that would be, she pondered.

As Gabby stared at her fake boyfriend's epic hard-on and instinctively licked her lips, the arousal that was violently stirring inside her was suddenly tinged with a cold sense of dread that caused her brow to furrow. Unblinking before Tyler as he rested his hands on his hips and stood proud and silent in front of her like a flesh and blood Greek statue, plus a ragingly erect horsecock that would put most male pornstars to shame, Gabby tried to speak a few times but couldn't do much more than gasp and mumble and keep ogling that gigantic slab of dickmeat. When she finally managed to string a few words together, Gabby also forced her gaze up from Tyler's monumental boner and met his piercing gray eyes. In them, she saw quiet triumph, alongside the fires of a roaring inferno of lust barely kept at bay by his straining iron will.

"You... You really pulled it off!" Gabby finally blurted out, shocked to the core, as understanding fully hit her and she was forced to accept Tyler's state of unprecedented hardness as the ultimate proof of her defeat. He had resisted! That was what had caused his dick to swell to such gigantic proportions. "You two actually made it through last night and today without fucking, didn't you?"

"Yes, we did," Tyler replied simply, flashing his pretend girlfriend a genial smile. Gabby didn't doubt for a moment that Tyler had spoken the truth. She knew he wouldn't lie on something like that, not after he and Michelle had both given their word. "We won, Gabs. It was very, very fucking hard," Tyler chuckled, shrugging his powerful shoulders at his own cheesy pun as he wagged his humongous erection side to side, letting a thick bead of precum drop wetly to the floor, "but yeah, we made it."

Letting out a sound that was part sigh, part gasp and part giggle, Gabby slowly nodded to herself as her dark cock-hungry eyes returned to stare at Tyler's mighty schlong. Somehow, even as the realization that she had lost sank in, Gabby felt a weird sense of growing relief swelling up inside her, an unexpected feeling of selfless joy surprisingly taking over the bitter taste of defeat, replacing it with the sudden awareness that she actually preferred this outcome after all. Yes, Gabby's inner voice slowly told her, it was better this way. It was right.

Paradoxically, Gabby found herself feeling glad that the siblings had won, because their victory indeed proved wrong the teasing idea she had floated about the two of them being unable to be together without fucking, as if their relationship had become reduced only to sex. Of course that was a lie, and Gabby knew it all along. Choosing that argument as the core of her bet had been a mere pretext, or so she had told herself the night before when she had cajoled Michelle and Tyler into one of her usual mind games. At that moment though, as she feasted her eyes on Tyler's painfully hard, massively huge cock, Gabby was hit by the thought that, in a twisted way, she had involuntarily offered the siblings a test to prove the pure, profound nature of their love, and they had passed. Gabby was happy for them, but for herself too, for having been accepted within the ever-glowing warmth of Michelle and Tyler's affection, which apparently had the power to turn even her impish schemes into positive opportunities!

Weirded out by the fact that, for all intents and purposes, she had unwittingly done something good while thinking she was doing something devious, stunned into uncharacteristic silence by the flood of realizations pouring into her brain in the blink of an eye while the image of Tyler's amazing monstercock still filled her vision, Gabby finally mumbled in a daze: "Well, fuck me..."

Unaware of the brunette's train of thought and of the crucial intuitions she was still processing, Tyler took her surprised exclamation at face value and chuckled jokingly in response: "Don't tempt me, Gabs. I'm so horny that I just might take you up on that offer and fuck you right now!"

Snapped out of her epiphany by those playful yet very appealing words, Gabby blinked up at a smiling Tyler and quickly gathered her wits. With a smirk and a raised eyebrow, she teasingly wagged her finger at him as she spoke.

"Now now, stud, I might be your girlfriend but we both know who has first dibs when it comes to your loads. And by the looks of your ridiculous boner," she concluded, pointing at Tyler's portentous precum-slick erection, "you must have a monster load stored up and ready to blow. If I get in the way of you dumping your cum inside Michelle's ass, I'm pretty sure she'd kill me. Like, seriously."

"That's right," Tyler agreed in a matter-of-fact tone, knowing that his sister would do exactly that.

"Well," Gabby added with a sigh, "I guess she's earned it. You both have. My god, you must be going crazy right now... I bet you both can't wait to have a nice deep buttfuck, uh?"

"Yeah," Tyler exhaled slowly, as if forcing himself to stay calm. "Mimi at least came while I ate her ass out, but it didn't really help. She's super horny now, and so am I."

Taking a better look at him now that she was less blinded by his distracting, pussy-drenching handsomeness, Gabby noticed the tension in Tyler's muscles, the way his jaw tightened as if he was physically straining to maintain control. No doubt the mere thought of releasing his long-deferred load deep inside his sister's heavenly pink butthole had him on the ropes, and no wonder.

"Come on," Gabby said, initially reaching to grab Tyler by the dong like she would normally have done but then thinking better of it, lest her touch turned out to be enough to set off his ejaculation, which seemed very plausible at the moment. Taking his big powerful hand in hers instead, the slender brunette dragged Tyler behind her as she swiftly started walking, headed upstairs. "We've gotta get you to Michelle right now. I don't wanna spoil your victory. You two are fucking champs, for real."

When Gabby and Tyler got to Michelle's room, the first thing they saw was her big heart-shaped booty hanging off the side of her bed and pointed right at the door as she lay languidly on her side on the rumpled covers. Beside being stunned for the umpteenth time by the luscious callipygian sexiness exuding from her petite friend's plump ass, Gabby didn't fail to notice the glinting sheen of saliva coating the inside of Michelle's sumptuous buttcheeks and the trails of shiny girlcum dripping from her smooth pussy and between her thighs to pool on the bedspread, all of which instantly confirmed to Gabby that Tyler must have been feasting on his sister's adorable little asshole for quite a while, with obvious orgasmic consequences for Michelle. At the moment, lying on her side by the edge of the bed, Michelle was mewling and panting as she pawed at her own huge bulging tits, pinching and pulling on her nipples in frustrated arousal, chasing a climax that, by the rules of the bet, she couldn't achieve by fingering herself.

A thin smile curled Gabby's lips as she took in the sight of Michelle, who seemed always at her most beautiful whenever she was so desperately horny, with her cute face flushed, her lust-glazed green eyes barely open and long rebellious strands of her light brown hair escaping her ponytail to fall across her pale, unblemished shoulders. Indeed, Michelle held a special fascination in the brunette's eyes right there and then: the considerable strength of character she had demonstrated by winning the bet impressed Gabby in the extreme, and even more so because she knew that her curvy friend's horniness was focused entirely on her big brother, for whom Michelle felt true love beside roaring, needy passion. Caught in her musings, Gabby had barely time to walk into the room and, before she could even speak and graciously admit defeat, Michelle had already rolled and turned her cure face toward her.

"Ah! We won, bitch! Mwahahahah!" Michelle exclaimed with a big goofy smile, her voice bright and her desire-clouded eyes shining with joy as she laughed out loud with exaggerated, cartoonish glee, going as far as letting go of her own massive boobs to point at the brunette. "You thought we'd fall for your 'rimming only' rule, didn't you? Well, we didn't! So bite me, you Machiavellian ho, you!"

The comical element in Michelle's display of triumph, combined with her nakedness and the silly lust-drunk vibe she exuded, made all three of them chuckle, binding them together in a general celebration of what was certainly a victory for the siblings, but wasn't entirely a defeat for Gabby somehow. As Tyler neared the bed, his monstrously erect boner slicing the air as it left a trail of trickling droplets of precum behind, Michelle was distracted from her celebratory haze, her evil villain style laughter turning into giggles and coos while she stared at that huge, mighty cock with unrestrained desire. Still, before she let herself drown in the liberating lust she would soon share with her beloved big brother, Michelle cast another glance Gabby's way and grinned broadly as she put on a haughty air and primly instructed: "Get naked, bitch! Time to eat my pussy while I finally get my ass pounded!"

"Sure thing," Gabby smirked with a shrug, all too happy to tear her clothes off and be naked like the siblings.

Once stripped, excited as she was to get started on Michelle's deliciously juicy pussy, and even more eager to watch Tyler sate his lust inside the warm tight confines of his sister's tiny bootyhole, Gabby couldn't help but frown as a thought struck her and forced her to intervene. Michelle was already rolling onto her tummy and Tyler's hands were firmly planted on her meaty asscheeks to help her get in position on her hands and knees when Gabby's voice resounded in the room: "Wait! Guys, wait a second, please!"

Turning to look at the brunette, Michelle and Tyler were both panting with anticipation and almost shaking with urgency. His humongous schlong was already pointed at her big round bubble-butt, dribbles of shiny precum trickling down to splatter on her soft fleshy globes and slithering their way into her luscious ass-cleavage, hitting the pink puckered orifice that Tyler so ached to penetrate and Michelle so needed to have stretched and filled to bursting by his horsecock. Given how horny they looked, Gabby was surprised that the siblings had even heard her and bothered to turn her way, so she wasted no time in blurting out her idea.

"Let's do this in your room, Tyler. So we can film it, you know? Guys, please, it's gonna be just a few more seconds, and it's gonna be sooo worth it! You have everything set up to record there, right? Come on, let's go to Tyler's room! This is gonna be epic, I know it is! We need to film this, guys, we just need to have it on video! Pleeeease?"

As soon as Gabby's breathless, desperate plea was over, Michelle and Tyler shared one of their meaningful looks. For a moment there was absolute calm and silence in the room, then Tyler turned and grinned at the brunette.

"You have a point," he conceded, shrugging his powerful shoulders, his hugely swollen boner flexing as if in protest against the prospect of a delay to the imminent assault of Michelle's willingly offered bubble-butt. Glancing at his sister, Tyler lifted an eyebrow and asked perfunctorily, already guessing that she would agree not to miss that obviously great chance to get some super hot stuff on video: "Mimi?"

"Okay, let's go to your room..." Michelle nodded at her brother, the barest trace of sulkiness in her voice. Then, letting out a giggle as her cute face scrunched into a theatrical pout, she added: "But you're gonna have to carry me. I came so much while you ate my ass that my legs are all rubbery and shaky now. I don't think I can even walk!"

*****

Rushing ahead of the siblings, Gabby was giddy with anticipation as she quickly set up their phones in the usual strategic places around Tyler's room and positioned his laptop on the desk right across the bed so that it had the best view of the imminent action. The brunette's nipples were tormentingly stiff with excitement and she was biting her lips when Michelle's giggles and Tyler's chuckles increased in volume, anticipating their arrival.

As she turned to see them cross the threshold, Gabby couldn't help but gasp and laugh and smile all at the same time, her dark eyes twinkling as she felt that strange warmth inside her that she never failed to experience around the siblings. At that moment more than usual, the visual impact of the two of them together was particularly indicative of their deep love for each other.

Holding her effortlessly in his muscular arms, Tyler was grinning at Michelle while she looked back into his eyes in smiling adoration, her petite curvy body pressed to his sculpted frame as he strode toward his bed with long, confident steps. Though she already knew that the two of them were perfect soulmates and were undoubtedly meant to be together, Gabby always marveled at the perceivable aura of loving affection that seemed to radiate off Michelle and Tyler, and even more so right there and then, as they were caught in that particular pose, so typical of a husband carrying his newly wed bride into their home. Indeed, the fact that the siblings were naked and that Tyler's preposterously huge erection was poking and slapping against the plump roundness of Michelle's big juicy asscheeks made that image much more powerful in Gabby's eyes, turning her on immensely with its mix of raw lust framed in tender love.

In the blink of an eye though, as soon as Tyler had crossed the room and after Gabby had the chance to get a quick passing glance at Michelle's lovely wet pussy, a sense of shared lust descended upon the trio and took over their actions, much to everybody's delight.

In one fluid motion, while Tyler laid his sister down on her back and pulled her closer so that her beautiful bubble-butt was hanging off the edge of his bed, Michelle wantonly parted her legs and drew them back against her large bulging tits, granting her brother total access to her holes. Still holding her slender arms locked around his neck, Michelle pulled Tyler closer as she moaned and panted, her lips puckering in an invitation to a kiss. As a growling, lust-addled Tyler leaned down and pressed his mouth to his sister's delicious lips, Gabby briefly wondered if the siblings had actually refrained from making out during their bet. Of course the brunette knew that Michelle and Tyler would have told her if they had in fact broken the rules, but the thought sprang up automatically given how passionately the two of them were kissing now!

Even as that needless doubt dissipated, Gabby's attention was captured by the pussy-moistening sight of Tyler's hand grabbing his humongous boner and guiding it to his sister's pink, spit-lathered sphincter, a gesture that made it unequivocally clear that the fun was about to begin. Forcing herself to remove her gaze from the scene for a second, compelled to turn and make sure one last time that the laptop was angled just right and that she had indeed hit record, Gabby gasped in awe as soon as her eyes darted back to watch Michelle and Tyler again.

Huge and pulsing and shiny all over with leaking precum, Tyler's bloated cockhead was already pressing urgently against Michelle's winking little hineyhole, the angry reddish purple of his broad glans completely covering the adorable pink pucker of her needy rosebud. The contrast between his fat bulbous tip and her miniature anal orifice awoke in Gabby the familiar thought that no, no way, there was absolutely no fucking way that a dick as indecently big as Tyler's could fit inside an asshole as cute and tiny as his sister's. Of course, at that point Gabby was very much aware of how well-trained Michelle's backdoor truly was when it came to welcoming her brother's horsecock up her ass, but still the brunette shivered with arousal and felt her dewy pussy tingle and moisten even more as she drank in the ever-shocking sight of Tyler's huge cockhead poking and prodding at Michelle's little bootyhole.

In truth, at that moment more than ever before, the idea that such a thick veiny schlong wouldn't manage to slip inside such a delicate-looking and adorably tiny sphincter seemed somewhat justified to Gabby, given the exceptionally overswollen state of Tyler's dong and the fact that the siblings didn't appear to be even remotely concerned about using any lube. Sure, the hour that Tyler had spent feasting on Michelle's anus had left her butt-ring extremely slick with spittle, and the impressive amount of runny precum coating his overswollen length looked slippery enough to do the trick, and yet Gabby did feel a moment of genuine uncertainty as she stared in rapt attention at Tyler's mushroom head bulging lewdly out against Michelle's rubbery pucker, his long iron-hard shaft meanwhile throbbing with his primal need to assfuck his beloved little sister after their enforced abstinence.

For an instant, time seemed to stop and everybody in the room held their breath while Tyler's large precum-oozing tip pressed against Michelle's lovely little sphincter, desperately pushing to punch through. Then, to the sound of their entwined kiss-muffled moans, the spell was broken and time started flowing again as the rim of Michelle's soft rosy orifice bloomed open, her butt-ring stretching out to obscenely sexy proportions and thus allowing her brother's huge purple cockhead to slide inside her asshole. Prompted by that epic sight and by the pleasure gasps that erupted from the siblings' conjoined mouths, Gabby's legs moved of their own accord and she rushed to the bedside, eager to get as good a look as possible.

Overcharged with horniness as she was, feeling like her well-rimmed butthole was positively on fire with the long-deferred desire to get stretched out and filled up and royally fucked by her brother's raging monstercock, Michelle felt like a knot of needy, antsy tension had finally come undone inside her and a bolt of lightning had just hit her, electrifying her docile curvy body and reviving her with a rush of physical joy as soon as Tyler's broad glans managed to widen her winking butthole into relaxing and opening up enough for his huge meaty pole to start slipping inside her ass. The familiar feel of stuffing fullness and the unique sensation of perfect completeness that she always got whenever her brother's dick pushed his way into her bootyhole washed over Michelle's very being, overwhelming her with even greater force than usual. Having been so horny for a buttfuck all day and having had her asshole teased and prepped and worship amazingly for the last hour, Michelle did expect to cum hard and fast once she finally got her well deserved dose of anally delivered dickmeat, but the intensity and quickness of her assgasm shocked even her.
