Michelle had just smooched her brother deeper in response and wiggled her big booty excitedly as she wrapped her legs tighter around his waist, quickly dissipating his concerns with a purring giggle.
“Already taken care of, Ty. I’m all lubed up for you. Go ahead, push your big fat cock all the way up my ass!”
And that was exactly what Tyler had done. Thrusting up while letting Michelle slide down on his rock-hard boner, using a combination of force and caution that reflected both his raging lust and his tender love for his amazing little sis, Tyler had gradually slotted his entire humongous pole as deep as it could go within the warm, heavenly tightness of Michelle’s narrow rectum, until her tautly dilated orifice was gripping and pulsing around the very base of his dong. The long, wanton mewl of anal ecstasy that had burst from Michelle’s smiling lips once his horsecock was jammed balls-deep inside her asshole was more than enough to clarify her pleasure, but the increased feeling of wetness that spread from her virgin slit and drenched his groin with her precious nectar made it even more evident to Tyler that his sister was truly loving how his throbbing schlong was stretching out her bootyhole and stuffing her narrow chute full to the limit.
Buried to the hilt inside her forbidden hole, Tyler had gladly paused for a few moments to enjoy the velvety ripples of pleasure that coursed through Michelle’s buttery passage and massaged his thick boner from tip to root. Then, as her head lolled weakly back so that her long hair was flowing freely across her slim shoulders, he had started pumping his hips and assfucking his sister’s incredible ass with all the love and lust he felt for her.
Holding Michelle possessively in his arms and digging his fingers into the juicy, amazingly plump roundness of her buttcheeks, Tyler had synced the bucking of his hips to match the motions he imposed on her surrendered little frame as he guided her up and down along his pistoning dong, making each booty-skewering penetration doubly intense. Thrusting over and over into the snuggest, steamiest recesses of her slippery anus, Tyler had made it a point to cram his veiny truncheon balls-deep into his sister’s cock-hugging rectum at every in-stroke while taking care to always leave a good half of his massive length cozily tucked inside her shaft-squeezing anal passage on the out-strokes, thus making Michelle squeal and cum non stop as she snuggled tightly in his strong, possessive embrace.
Synching flawlessly together, fusing once again into that shared sense of sensuous completeness that they never failed to obtain whenever they had buttsex, Tyler and Michelle had moaned in joined delight all through that spontaneous assfuck, which was their third anal coupling of the day but also the first one ever standing up. Only vaguely acknowledging that element of absolute novelty, much more interested in relentlessly immersing his raging horsecock all the way up into his sister’s incredibly tight and sinfully warm anal depths, Tyler had taken particular pleasure in the animalistic, primal rush he got from sodomizing Michelle while holding her closely in his arms, the physical exertion inherent in the act indeed amplifying his sexual enjoyment of it.
The mind-boggling intensity of their buttfuck had certainly possessed a powerful rawness to it, which was made very clear by the urgency with which Michelle’s arms and legs clung to Tyler’s muscular frame while her huge rack was squashed against his chest and her whole petite curvy body was bounced up and down on his rump-impaling schlong. While her brother grunted and groaned in unrestrained delight, pumping his huge dickmeat all they way inside her indecently cock-hungry bootyhole without pause, Michelle had felt happily faint, overwhelmed as she was by the crashing waves of all the back-to-back assgasms that Tyler’s frenzied butt-cramming rhythm was gifting her. Her anal-centric bliss had been truly enhanced by the deep-seated satisfaction of being held with such ease in the arms of her strong, beloved big brother, whose incredible ass-plowing monstercock was making her see stars and sending rivulets of her liquid pleasure gushing incessantly from her pussy.
Eventually, after Michelle’s girlcum had thoroughly drenched his groin and her climaxing anal tunnel had suckled and tugged and caressed his recklessly thrusting schlong so much and so amazingly that he couldn’t hold back his ejaculation any longer, Tyler had felt compelled to shift position and break the so far uninterrupted tempo of their standing poolside assfuck. To the sound of his sister’s adorable sexy squeals and sigh-infused giggles, Tyler had rammed his fat sausage to the hilt inside her rippling rectum and left it stuffed in there as he marched across the backyard and into the house, only to instantly stop at the nearest wall and pin Michelle’s back against it.
With the wall helping to support her, Tyler had gained all the added stability he needed to unleash the final booty-busting assault with which he meant to give Michelle a big brain-melting assgasm while also allowing his impending ejaculation to finally explode deep inside her lovely butthole. Horny as they both were and electrified by the mixture of lust and love that joined them so perfectly together, the siblings hadn’t taken long to reach their respective and equally earth-shattering climaxes. Furious yet infused with the purest passion, the barrage of ass-plundering thrusts that Tyler let loose on her twitching little anus had sent Michelle into orbit, making her scream rapturously while wave after merciless wave of anal-centric bliss crashed into her with the very same breathtaking force of her brother’s balls-deep slams.
Of course, Tyler’s rabid butt-busting blitz couldn’t last too long, but its ending had marked a new pinnacle for his own and his sister’s shared anal pleasure. As he howled in release, Tyler’s ejaculation had erupted with deluging force from the bloated tip of his fully buried monstercock, hosing Michelle’s dick-squeezing chute with rope after massive rope of cum and triggering an assgasm so epic that her vision flashed white and she pretty much passed out on the spot, her slack limbs still wrapped around Tyler’s sculpted body, her twitching and insanely crammed bootyhole filled to bursting with throbbing dickmeat and warm, brotherly seed.
