The bulge in Tyler’s trunks reached obscene proportions as he watched his naked sister get on her hands and knees on the recliner with her epic booty tilted up toward him. Michelle kept that enticing pose on all fours for a few seconds, then she wiggled her big bouncy asscheeks a little bit and sensuously leaned down, until she was lying on her tummy like the day before. As her brother drank in the plump perfect roundness of her protruding rump, Michelle looked over her shoulder at him and pointed out: “You’ve gotta be fully naked too, Ty! I mean, it’s only fair, right?”
The intoxicating mixture of trepidation, excitement and simmering lust that dripped from his sister’s words struck a nerve deep inside Tyler, because the emotions ringing in her voice perfectly mirrored his own. Emboldened and reassured by the fact that he and his adored little sis were still as attuned to each other as ever even in that weird, almost surreal situation, Tyler nodded vigorously at Michelle and proceeded to get rid of his trunks as if they were on fire. The irrepressible gasp of awe that his sister let out as soon as his massive boner was revealed in all his raging, meaty hardness egged Tyler on even further, bringing a broad grin to his face as he approached her.
“There we go, fully naked it is!” he said before grabbing the bottle of sunscreen lotion and eagerly getting into position on the recliner like the day before, straddling Michelle’s shapely thighs while sitting up on his knees.
“Whoa, Ty… Fully naked and super hard too!” Michelle quipped as she flashed her hunky brother a mischievous smile, her eyes all the while drawn irresistibly to the awesome vision of his enormous erection bobbing and flexing menacingly mere inches above the bulging curve of her bubble-butt.
Chuckling and enjoying the lustful way his sister stared at his huge boner, Tyler poured a liberal dose of sunscreen on Michelle’s fabulous booty and started eagerly rubbing the slick lotion all over the plump roundness of her jiggly buttcheeks. Immediately, Tyler’s ass-kneading motions caused him to rock in place slightly, which made his thick hardness come repeatedly in contact with Michelle’s upturned rump. The feel of her brother’s beefy balls bumping into her curvy ass as his girthy shaft brushed and rubbed against her soft buttcheeks over and over again made Michelle all tingly with arousal, giving her the courage to push things even further.
“You know, Ty, you really should put on some lotion too… I mean, you don’t want to get your boner all sunburned, right?” Michelle asked in as casual a manner as she could muster considering how crazily her heart was beating at the prospect of what she wanted to do next.
“You’re right, Mimi,” Tyler agreed, kneading his sister’s juicy asscheeks even more devotedly and letting his long pole brush all over her bouncy globes ever more carelessly as he boldly added: “But maybe you should do it. I’m already kinda busy with your butt here, you know…”
Excited by her brother’s naughty reply, Michelle’s let out a silvery giggle and took a big steadying breath before she looked at him over her shoulder and said: “I’ve got an even better idea, Ty. How about this…”
While her words were still hanging in the air, Michelle reached back with her hand and grabbed her brother’s enormous truncheon in a possessive grip. The feel and sight of his sister’s dainty digits suddenly wrapped around his girthy, powerfully throbbing dickmeat coaxed a delighted gasp from Tyler’s mouth, soon followed by a long groan of pleasure as she slowly started massaging his overswollen schlong. Treating Tyler’s boner to a few slow jacking strokes was enough to make Michelle’s virgin pussy soaking wet with arousal, she was so thrilled to be finally touching and holding and masturbating her brother’s massive dick. Still wanting more, Michelle didn’t wait long before she guided Tyler’s huge shaft between her plump buttcheeks, nestling his meaty length in the cozily softness of her ass-cleavage.
While she shivered at the feel of Tyler’s fat cock flexing between her sumptuous globes, Michelle flashed her disbelieving brother an impish grin as she giggled and blurted out: “Okay, so we’ve got a big sausage, we’ve got the buns, now just squeeze some ketchup on that hotdog and we’re good to go!”
That goofy yet somehow appropriate tension-breaking joke made the siblings laugh in unison, but it didn’t stop Tyler from letting go of one of Michelle’s juicy asscheeks, grab the lotion, turn the bottle upside down and let a long dribble of it plummet right on top of his hotdogged boner, completing the sexy picture she had just evoked. Their complicit chuckles were still echoing in the sun-flooded backyard as Tyler once again filled both his palms to overflowing with Michelle’s plump globes and squeezed them lustfully.
Looking her right in her lust-shiny eyes he simply said: “You’re so awesome, sis!”
To the sound of her glad giggles, Tyler held Michelle’s bouncy asscheeks hungrily in his hands and pushed them snugly together, smothering his enormous truncheon within their pillowy roundness. At the same time, he gently started rocking in place, sawing his cockmeat back and forth between his sister’s big buttcheeks with slow, long humping strokes that made her glorious booty jiggle mouthwateringly and caused Michelle to purr like a sexy kitten. As if having her brother’s impressive schlong gliding between her meaty buns wasn’t exciting enough, the sensation of Tyler’s veiny shaft rubbing sickly against her sensitive pink rosebud was making Michelle shiver all over, causing more and more of her sweet juices to dribble from her smooth little pussy.
“Mmhh, that feels so good…” Michelle cooed while her brother kept pumping his cockmeat between her lotion-slippery asscheeks, his rhythm slowly but surely increasing at each pass. “Do you like it, Ty? Do like tit-fucking my big butt?”
“I love it, Mimi!” he replied truthfully, his hands pawing and kneading and massaging the cushiony fullness of her plump rump as his achingly hard pole slid fluidly back and forth in her luscious crevice. “Your ass is fucking incredible, so big and round and beautiful… And it feels so soft around my dick, it’s awesome!”
“Have you, uhm… Have ever done this before, Ty?” Michelle couldn’t help but ask, even though she already knew the answer. Still, even the remote possibility that her brother might have shared that experienced with another girl caused Michelle’s voice to tremble with fear and jealousy, a detail which Tyler noticed and found cute in its total absurdity.
“No, never,” he was quick to reply, dispelling Michelle’s momentary worry and causing a long sigh of relieved pleasure to escape her parted lips. “But I thought about it, Mimi, about doing it with you…” Tyler added, humping his little sister’s ass-cleavage deeply and deliberately, letting his whole length glide between her fabulous buns and rub over her adorable tiny asshole. “I think about doing a lot of stuff with you, sis. You’re the only girl of my fantasies.”
Overjoyed and totally reassured by her brother’s words, Michelle mewled with delight and urgently brought a hand underneath her prone body, reaching straight for her drooling pussy. As her fingers started feverishly circling her nectar-wet clit, Michelle flashed her brother a scorching hot glance over her shoulder and blurted out what sounded to him like the sexiest mix of a needy plea merging with a firm demand.
“Do it, Ty… Tit-fuck my butt with your big fat cock! I love doing this with you, I wanna do everything with you, only you!”
“Oh fuck, Mimi!” Tyler murmured, his boner flexing between her soft asscheeks, his heart bursting in his chest as a storm of lust and love for his awesome little sister raged deep inside his very being.
Overwhelmed by the intensity of his feelings, with the image of Michelle’s beautiful and radiantly excited face filling his eyes, Tyler let his instincts take over and leaned down until his mouth met hers in a scorching hot kiss that she reciprocate instantly. None of the affectionate smooches the siblings had shared before had ever been anything like that deep, passionate soulkiss, and yet their torrid make out session was so spontaneously steamy that Michelle and Tyler looked like they had done nothing but French kiss each other all their lives.
As their lips and tongues danced together flawlessly, Tyler sank his fingers even more possessively in the glorious plumpness of his sister’s big bubble-butt and began sawing his throbbing boner even more vigorously between her lotion-slick asscheeks. Those round bouncy globes felt so incredibly good as he squeezed them in his palms, and what they were doing to his rapidly pumping schlong was simply amazing. Soft and full and meaty, Michelle’s pillowy buttcheeks enveloped his aching erection in a perfect dick-pleasing hug while the sheen of lotion coating both his thick shaft and her luscious crevice made it easy for him to plow her ass-cleavage as vigorously as he wished.
As if the warm cushiony embrace of the booty of his dreams wasn’t already an awesome enough sensation for Tyler, the fact that at each stroke he could feel the puckered rosebud of Michelle’s asshole twitch with excitement along the underside of his raging horsecock was making him mad with lust, egging him on to hump his sister’s cozy, slippery butt-crack even harder. All the while, the sexy pulsations of her tiny asshole didn’t only confirm Michelle’s delight and desire, but they also reminded Tyler that, as great as it felt to fuck her epic booty on the outside, even greater pleasures awaited him inside the unplumbed depths of his little sister’s adorable forbidden hole.
Moaning into her brother’s smooching lips and lewdly sucking his tongue into the liquid heat of her mouth, intoxicated by the feel of his hunky body hunched over her petite frame, Michelle squirmed with horniness and rocked her ample booty back and forth in an attempt to match Tyler’s lustful rump-humping rhythm. The growing speed and force of his thrusts into her ass-crack increased the slick, amazingly pleasurable friction of his veiny truncheon rubbing incessantly against her butthole, making Michelle’s pussy leak rivulets of her nectar all over her clit-strumming fingers. All the while, her rocking motions caused her big jutting tits to wobble all over the place as well, so that her puffy nipples grazed constantly against the rough cloth of the recliner’s cushion, adding yet another layer of delight and enhancing her quickly simmering climax.
