Little Sister's Big Butt Ch. 05

*****

Unsure how to feel about the unexpected twists and turns that the evening had taken, much calmer now but still mildly shocked by the general weirdness and emotional shakiness of it all, Tyler spent a solid quarter of an hour sitting on the edge of Gabby's bed while the girls sat at her desk, going over the ample collection of home-made incestuous double anal clips and pics she had stored on her laptop.

"Oh, this one here is pretty good too," Gabby was saying, calling the attention of an ever more giddy Michelle to yet another one of her videos. "It's actually one of my favorites. Eddie did a good job editing this, I gotta say."

"Holy shit, look at that gape!" Michelle exclaimed, barely hearing what Gabby was saying, her mouth slack with awe, her eyes bugging out of her skull as they remained steadily glued to the screen in front of her, much like they had done since the brunette had fired up her laptop. "Jeez, that's so fucking hot! Ty, you've gotta check this out. It's amazing!" Michelle cried out, too mesmerized by the antics of Gabby and her buttfucking cousins on screen to turn all the way around and notice the vaguely bored expression on her brother's face.

"Sure, maybe later..." Tyler replied blandly, unable to share his sister's enthusiasm for Gabby's private porn stash. Not that he didn't like it, but after he had watched the first few videos of the twins ramming their dongs up Gabby's anus together and a couple of folders full of pics of her gaping and cum-drooling asshole, the novelty had simply worn off for him.

Plus, he could always watch it all later, which seemed indeed unavoidable given Michelle's lewd fascination with the brunette's booty-stretching skills. For his part though, as much as he did recognize how hot Gabby's double anal videos were, Tyler still couldn't fully appreciate them. It just seemed unthinkable to him that a guy would let another guy bang his girl in the ass at the very same time he was in there: to Tyler, that was just crazy. Of course, he knew very well that whatever arrangement Gabby and her cousins had, it couldn't be anywhere near as loving and affectionate and deeply intimate as his own relationship with his sister, but still Tyler remained baffled by the general idea of fucking any hole that was already occupied by another dude's dick.

And yet, even as he sat somewhat awkwardly on Gabby's fluffy bed and distracted himself by taking in the kind of details he hadn't bothered to notice the night of the party, first and foremost the significant number of Emily The Strange posters and books and assorted gadgets peppered around the room, Tyler still couldn't help but sport a visible tent in his pants, courtesy of the sexy background moans and grunts and assorted booty-plowing noises blaring out of Gabby's laptop speakers.

"Okay, girl, gimme your phone and let's get it loaded up with my best and filthiest work!" Gabby chuckled as she fished out a USB cable from a desk drawer and plugged Michelle's cell to the computer. "So, this one, this one and those and I assume all of these pics too, right?"

"Yeah yeah yeah, totally!" Michelle promptly agreed. Her excitement was so blatantly transparent as she stared in rapt anticipation at the progress bar marking the transferring of the files, that it made Gabby laugh and glance at her with sardonic inquisitiveness.

"So Michelle, tell me... Were you always into double anal, or am I due some credit here?" the brunette asked, her overtly complacent tone making it clear that she had only thrown in the first half of the question so that she could stress even more the part about her own merits.

"Oh, it's all your fault, one hundred percent!" Michelle quipped back, giggling and playfully elbowing the brunette, hitting the side of her barely covered boob and enticing a shared burst of laughter. Feeling weirdly connected to Gabby now that they had somehow bonded over her DAP videos, Michelle went as far as adding in a mumbled tone: "We even tried doing double anal too... You know, with a dildo..."

"Really!?" Gabby perked up visibly, looking at a blushing Michelle with renewed if lewdly motivated respect. "Come on, girl, tell me all about it! How was it? I bet you loved it, didn't you?"

"Well, no, not exactly..." Michelle shrugged, making a funny face as she turned and smiled at her brother, who had reacted to her unexpected admission of their recently failed incursion into double anal territory with stoic resignation.

After all, Tyler reasoned, Gabby knew their secret already, and she did seem trustworthy enough in spite of her quirks. Also, she was kind of the best person for Michelle to discuss that specific topic, what with being an expert in the field of double anal and the only person to whom they both could talk openly about their incestuous escapades. On top of those considerations, the bright-eyed warmth that Michelle exuded as she locked eyes with him couldn't help but bring a smile to Tyler's sealed lips; indeed, the mere fact that his sister wasn't scared or worried anymore jolted him with a welcome, full-body rush of joy. But it was what Michelle added and the laugh that accompanied her final statement as he turned her gaze back to Gabby that fueled Tyler's good mood even more.

"Ty's got such a huge dick," Michelle truthfully said, smiling with slutty joy, "I just couldn't fit anything else in my butthole!"

After giggling and turning her swivel chair around to flash Tyler a naughty grin, Gabby commented: "He's that big, uh? I couldn't tell too much from the video, but yeah, it looked like he's packing a pretty huge dick alright. And he sure knew how to use it. You lucky bitch, you!" the brunette concluded, planting a resounding slap on Michelle's plump shorts-clad bubble-butt that made her squeal in surprise, thus joining Gabby's own throaty laughter and Tyler's more contained chuckles.

"Anyways, if you need some pointers on how to get your juicy booty double boned, you may refer to these instructional materials here," Gabby said with comically exaggerated mannerism as she handed back Michelle's phone, concluding with: "And feel free to consult me for any advice in the fine art of taking two fat dicks up your ass, young lady!"

After accepting her cell from Gabby's hand with matching playful grace while laughing along with her, Michelle scampered her way toward her brother, her eyes zeroing in on his bulging crotch as she cheerfully replied: "Thanks, but I think I'll just stick to taking just one dick at a time for now. This one!"

Giggling and smiling, Michelle ceremoniously sat sidesaddle on Tyler's lap, making sure that her big round bubble-butt was pressing firmly against his pants-trapped boner, nestling it between her bouncy asscheeks. As she threw her arms around her brother's neck and snuggled in his prompt embrace, Michelle rocked and ground her ass against his growing tent, bringing Tyler's imprisoned schlong to full aching hardiness in a matter of moments.

Spurred on by the unfailingly arousing effects of being physically close to each other and now mellow with the relief they shared about having oddly yet seemingly very efficiently defused the potential risks inherent in Gabby's discovery of their secret, the siblings didn't show any sign of hesitation nor restrain as they let their bodies snuggle more tightly together, their lips spontaneously joining in a deep loving soulkiss right there and then, on the brunette's bed and before her greedily staring eyes.

The pure and simple passion that Tyler and Michelle conveyed in their kiss hit Gabby much harder than she may have expected, as did the way Michelle held onto her brother's strong body as he wrapped her in the embrace of his muscular arms while possessively planting his hands on the ample meaty globes of her shorts-clad ass. It wasn't just the hotness of that forbidden kiss nor the easy, natural attunement evident in the siblings' non-verbal language that affected the brunette; there was some kind of aura of love and affection and mutual devotion surrounding Michelle and Tyler when they were near, a vibe they communicated always when they were together, a perceivable sense of harmony and completeness that even a sarcastic, prematurely jaded hedonist like Gabby couldn't help but find nourishing, awe-inspiring and primordially sensuous.

Leaning back in her chair, the brunette watched in religious silence as Michelle and Tyler forgot all about her or anything else in the world and just lost themselves in their prolonged moment of smooching, lip-locking communion. By the time the siblings' brief but intense kissing trance ended and their mouths managed to pry themselves apart, Gabby had slipped her hand inside her damp bikini bottoms and was caressing her clit with slow circular motions, her other hand meanwhile distractedly playing with her turgid nipples in turn through the flimsy, sodden fabric covering them.

Turning toward their horny hostess together, Michelle all the while grinding her plump ass against Tyler's pants-caged dong as his hands kneaded her big protruding buttcheeks through her shorts, the siblings didn't even have time to say a word before Gabby whistled and exclaimed: "Wow, that was really hot, and it was just a kiss! And you haven't even taken off your clothes yet! Speaking of which..." she concluded with a snicker while briskly undoing the knots of her bikini and letting that skimpy cover fall off, leaving her totally naked and granting her nervous fingers better access to her tingly, juice-glinting pussy.

"So," Gabby purred as she nonchalantly resumed her languid nipple-tweaking and clit-rubbing manipulations, "care to get naked too, guys? Now that you have my videos and I have your video, all we need to be even stevens is for you two to give me a live show!"

Excited as they were by the brunette's nudity and by the fact that she had been turned on by their kiss enough to start diddling herself in front of them, already achingly hungry for each other, Michelle and Tyler still paused and shared a quick glance before answering.

"I guess that's fair..." Michelle began, half tentative and half excited about the idea of being watched while having sex with her brother. "Right, Ty?"

"Yeah, I guess so..." he conceded, shrugging his powerful shoulders while trying to think clearly about the situation in spite of the fact that his clothes-caged, massively swollen boner was yelling for him to just fuck his beautiful sexy sister right there and then, and to hell with whoever was watching. After willing himself to be as rational and lucid as possible about what was going on, Tyler answered Michelle's persistent questioning look and Gabby's smirking gaze by exhaling and nodding slowly while saying: "Yeah, sure. Let's do it."

"Excellent..." Gabby gleefully murmured in her best Mr Burns impersonation, whose rendition was somewhat impaired by the fact that she refused to remove her hands from their tits-massaging and pussy-caressing tasks to accompany the signature line with the Simpsons villain's characteristic hand steeple gesture.

Still, her performance didn't fail to get a laugh out of the siblings, who were still chuckling even as they locked eyes and started urgently taking off one another's clothes. Purged of all previous misgivings and surrendered to their roaring passion for each other, Michelle and Tyler removed the other's top within moments, her hands then rushing to his bulging crotch to take off his pants while he deftly freed her huge jugs from her bra. Even more than the sight of Tyler's strong manly pecs and chiseled abs, the vision of Michelle's large, pillowy yet gravity-defying rack made Gabby's deep brown eyes widen with awe and brought a gasp to her parted lips.

"Fuck me, girl! Those are some seriously fucking big titties! They're not as epic as your ass, but still... Wow!"

Giggling and blushing adorably yet undeterred in her mission to take off her brother's pants and free his fat schlong from its present confines, Michelle spared Gabby a quick thanking glance as she replied with a smile. "You have nice tits too. All firm and perky, and shaped just right."

"Oh, I know. It's not that I'm complaining or anything," Gabby exhaled lazily while arching her eyebrows and giving each of her sensitive nipples a distracted but still pussy-wetting pinch, "but sometimes bigger is better, that's all I'm saying. And speaking of big..." she added, her voice getting huskier and trailing off before finally fading to a gasp the moment she saw Michelle yanking down Tyler's pants and boxers, thus unveiling his ragingly hard monstercock in all of its meaty hugeness.

Rabidly excited knowing that her brother's overswollen boner was throbbing with desire for her, Michelle got rid of her remaining clothes with wild eagerness and swiftly dropped to her knees before Tyler. Licking her lips as her gaze traveled from his massive dickmeat to his piercing gray eyes, Michelle didn't let more than a couple of lust-charged seconds go by before she grabbed her brother's pole by its thick base and dove down face first, jamming his purple knob plus a few veiny inches of his shaft into her cock-starved mouth and instantly starting to blow him.

"Wow... That is a big dick!" Gabby mumbled almost to herself, her fingers rubbing her pussy faster as she watched Michelle's soft suckling lips slide up and down along Tyler's dong with such passion and such genuine, sinful need to cram her brother's enormous sausage down her gullet that the mere sight got her dizzy with vicarious excitement. As she stared raptly at Michelle slurping and bobbing and slobbering away all over Tyler's mighty pole, Gabby couldn't help but jokingly add: "No wonder you couldn't take anything else up your butthole. That monster is as thick as both my cousins' dicks combined! You're a brave bitch to try double anal with that, Michelle!"

That doubly flattering yet obviously exaggerated comment made Tyler chuckle, inducing him to flash Gabby a pleased grin. At the same time, it also caused Michelle to giggle and therefore immediately gag on her brother's throat-clogging truncheon. Emitting a series of wet slurping sounds that were somewhere between squelching dick-muffled laughter and sloppy suctioning smooches, Michelle slowly let the fat length of Tyler's boner emerge from her constricting gullet and slide all the way out her oral cavity and past her saliva-glossy lips before she finally turned to the brunette with an expression of mock-anger painted on her amused, lust-flushed face.

"Gabby," Michelle began with what little sternness she could muster given the fact that her hand was still stroking up and down the left of Tyler's monstercock and a shiny, dangling string of precum-laced spittle connected her lips to his bulbous glans, "please, don't make me laugh while I give my brother a blowjob. It's very distracting and it could make me choke."

Admiring Michelle's spirit as much as her remarkable cock-sucking skills, Gabby nodded agreeably and replied with theatrical formality. "My apologies. Please do continue your forbidden fellatio, it's quite a sight to see."

Emboldened by the brunette's playfulness and appreciation, Michelle redoubled her schlong-gobbling efforts, much to her own and her brother's pleasure, not to mention Gabby's voyeuristic delight. Soon the room was saturated with loud slurping and moaning sounds, Michelle's sexy dick-muffled mewls increasing in volume the faster and deeper she sucked away at Tyler's overswollen pole.

Always strumming her clit and panting ever more raggedly, Gabby remained as quiet as possible while drinking in the spectacle of Michelle kneeling between her groaning brother's legs, her big round booty sticking out as her head bobbed devotedly up and down, her soft saliva-shiny lips wrapped lovingly around his enormous dickmeat, her dainty left hand wrapped around the root of his shaft and happily stroking away while her right hand was put to work between her legs, rubbing frenziedly at her juice-dripping clit. Initially just another hot detail in that scene of incestuous pleasure, the rhythmic sway of Michelle's huge tits jiggling and wobbling in time with her lustful cock-inhaling tempo soon became the key detail that captured Gabby's attention, eventually leading her to speak up after a long interval of awe-struck silence.

"Fuck, you two look so hot together, so... Complementary, I guess is the right word?" the brunette mused, her voice husky from the rippling mini-climaxes she was giving herself by restlessly circling her pussy-teasing digits all over her engorged clit and nectar-slick labia. "Look at those massive tits, they're the perfect match for such a huge fucking monstercock..." Gabby murmured to herself before emerging from her contemplative mood with a snicker, only to immediately address a moaning, lust-high Tyler. "I bet you just love fucking your sister's big soft titties. Don't you, Tyler?"

Grunting with pleasure as he enjoyed Michelle's awesome blowjob, Tyler looked at Gabby with glassy eyes and just nodded in reply while cracking a broad, ecstatic smile. All the while, his hands kept caressing his sister's bobbing head, his fingers playing with her long light brown locks as her wet warm mouth worked its dick-engulfing magic on his achingly hard schlong. Immersed as she was in her own lascivious cocksucking haze, tingly with delight while she frigged away at her nectar-squishy clit with a desperation that matched her gusto in cramming her brother's massive shaft down her saliva-lubed throat, Michelle didn't fail to hear Gabby's words too, and indeed took them as a not-so-veiled invitation for her to show off more of her slutty tricks.

Surprising Tyler and leaving him panting and grunting and aching for more of her superb fellating attentions, Michelle suddenly interrupted her blowjob and let her brother's raging horsecock slide all the way out of her oral cavity until it plopped out of her talented mouth with a lewd slurping sound. Towering rigid and coated all over with a slippery sheen of spittle and precum, Tyler's enormous dickmeat throbbed obscenely before Michelle's pleasure-foggy eyes for just a second, not even long enough for him to complain about that unexpected development. Within moments, Michelle removed her pussy-diddling hand from between her legs, brought it to her lips to quickly lick up her own sweet juices off her fingers, and then straightened up on her knees while pushing her ample rack forward, thus nestling Tyler's overswollen pole between her round jiggly tits. As she cupped her own massive boobs with her dainty hands and pressed them snugly around her brother's rampant erection, Michelle looked up to see his expression shift from momentary puzzlement to instant bliss, the dick-hugging softness of her fleshy melons immediately compensating for the loss of her lips and mouth and gullet servicing him in concert.

"Fuck yeah! Aahh, Mimi, yeeess!" Tyler grunted as Michelle started expertly guiding her heavy jugs up and down along the veiny, girthy length of his shaft, treating him to an amazing titfuck that was made slicker and sexier by the layer of saliva she had lathered all over his dong during her intense blowjob.

Soon enough, Tyler's words of appreciation degenerated into basic albeit obviously enthusiastic groans of pleasure when his giggling little sister winked at him, flashed him an adorably innocent smile that somehow made her present sluttiness even sexier, and then dipped her head down so that she could wrap her fantastic lips around the big pulsating tip of his dick. Keeping up the shaft-stroking motions of her bulging tits, Michelle made Tyler see stars as she began suckling and smooching and lapping away at his swollen glans, mewling sloppily as she licked up and drank down the copious stream of precum that she was milking out of him with her cock-smothering rack. Crazy horny and nearing climax, Tyler reacted to that incredible combination of pleasant stimuli by bucking his hips excitedly between Michelle's huge round tits, fucking her saliva-lubed cleavage with quick, urgent strokes that testified to his savage need to pay homage to his own personal sex goddess of a sister with a generous offering of his brotherly cum.
