It had been four days since Michelle and Tyler’s unlimited buttfuckfest had begun when Ellie called them to announce that finally, after one last business lunch the next day, she would be free to jump on the first plane headed home.
Despite the unavoidable dampening effect on their lust-induced high spirits, the news of their mother’s imminent return did also bring some genuine joy to the siblings, who were always glad to spend some time with their mom and knew that she would be overjoyed to see them, as she always was after a business trip. Indeed, rather than souring their mood, the knowledge that they only had roughly twenty-four hours left to go crazy before they had to return to their usual and more careful ways to sneak some quality assfucking time together acted as an incentive for Michelle and Tyler, who felt that they had to make every moment count now that the clock was ticking for real.
Due to that rush of urgency, the siblings had a particularly fun time during their lunch break that day, with Michelle taking the initiative and recklessly impaling her big juicy ass on Tyler’s raging horsecock, riding him in a reverse cowgirl position as he sat back on a pile of deck-lounger cushions. Watching his sister wildly bouncing her plump bubble-butt on his overswollen pole right after her deliciously gaping, lube-dripping asshole had gobbled up his entire veiny schlong in one single rectum-stuffing plunge was already insanely hot for Tyler, but the sight of Michelle’s delicate hands sneaking their way under her top and past her bra, so that she could pinch and pull on her own stiff pink nipples while she crammed his horsecock deep inside her sweet heart-shaped ass without pause, drove him even crazier with lust and led him to turn his pawing and kneading and cupping caresses on his sister’s glorious jiggly booty into ever firmer and louder spanking slaps.
Beside making her already mouthwateringly bouncy rump shake even more and creating another layer of fleshy sounds on top of the steady clapping beat of her big round buttcheeks impacting against his thighs, Tyler’s passionate ass-spanking made Michelle mewl in naughty surprise and appreciation, her muffled vocalizations clarifying just how much she liked that treatment even if the buttplug jammed into her mouth partly silenced her sexy moans. Indeed, the very fact that the robust plastic toy was keeping Michelle from fully crying out her wanton delight, thus also preventing him from hearing the nuances of all the spikes in loudness and pitch that occurred every time he brought his hands down on her majestic cock-engulfing ass, somehow ended up turning Tyler on even more. Muted and muffled as they surely were, there was nonetheless no doubt about the deeply appreciative quality of Michelle’s mewls, and the fact that she was loving that impromptu spanking was further demonstrated by the fact that her self-impaling bouncing rhythm kept growing more and more reckless the harder Tyler’s palms hit her gorgeous, meaty buttcheeks.
Overcharged with anal passion as they both were, that day the siblings managed to speed up their quickie to record times, both of them reaching massive orgasms much faster than they usually did. At the time same time as Michelle slammed her luscious bubble-butt down in a final sphincter-stretching bounce that pushed her over the edge and sent her dick-packed bowels into a shaft-constricting frenzy, Tyler’s climax instantly hit him too, right while he was bringing both hands down one last time on the round, pillowy and at that point slightly reddened hillocks of her asscheeks. Buried to the hilt inside her epic booty, milked flawlessly by her twitching, overdilated butt-ring and by her rippling anal walls, Tyler pumped a prodigious ejaculation deep inside his adored little sister’s ass, filling her soft narrow rectum with so much cum that some thick pearly globs even managed to squeeze their way out of the tightly encircling rim of her orifice and seeped all over his groin.
With her delicate hands still cupping her own huge tits and her digits lazily teasing her sensitive nipples, a panting and pleasure-dazed Michelle was somewhat surprised when she felt her brother’s hands leaving their usual perch on top of her big and now deliciously smarting asscheeks only to reappear right before her unfocused eyes, his fingertips dripping with thick white globs of his freshly spurted cum. Removing the buttplug from her mouth, Michelle grinned impishly at Tyler as she turned to blow him a kiss over her shoulder, and then eagerly parted her lips so that he could feed her his runoff seed.
As they savored their afterglow still joined together, with Tyler letting his enormous boner soak in the cock-suckling tightness of her warm creamy chute and Michelle gently grinding and rocking on his lap to stir her buttery bowels with his thick pole and make sure that her asshole stayed snugly wrapped around its very base as more and more squeezing anal spasms milked his balls dry to the last drop, the siblings remained silent but traded scorching hot glances that were more explicit than any words, Tyler all the while dutifully retrieving any trace of pearly sperm escaping Michelle’s impossibly stuffed orifice and then offering it all to her greedy mouth. By the time they had straightened themselves up and were ready to get back to work, they had already sent a few pictures of Michelle’s beautifully plump and dick-skewered ass to Gabby, each image clearly showing the reddened imprints of Tyler’s hands on her sumptuous, milky white buttcheeks.
When her phone chimed upon receiving Gabby’s reply, Michelle was already grinning in naughty anticipation, expecting her friend to vent out a bit of her understandable jealousy or to dish out one of her characteristic sassy comments. In fact, Gabby’s text conveyed something else, something better all around, as Michelle promptly informed Tyler with a big smile on her lips and a twinkle of playful mischief in her green eyes.
“Gabby says that her ‘family thing’ is over and she’s dying to have some ‘serious fun’ with us!” Michelle giggled, biting her lower lip and raising her eyebrows suggestively. “Do you think we…”
“… should invite her over after work?” Tyler finished with a chuckle, easily reading his sister’s mind and agreeing with the obviously naughty intentions that were written all over her flustered, lovely face. “Yeah, definitely.”
“Yay! This is gonna be great!” Michelle exclaimed in an adorable burst of excitement, jumping happily in place and thus making her huge gravity-defying tits jiggle deliciously under her top as she tapped away at her phone to give Gabby the good news.
