The Book of Power

Looking at her nephew lying on the bed, his cock fully erect and waiting for her to "check his virility," Elli bit her lower lip and slowly undressed, revealing her smooth, sexy body.

She obediently spread her legs and lowered herself until her pussy hovered just above his face, then gently pressed her swollen labia against his mouth.

Her beautiful sex was once again fully exposed to him. 

Max immediately stretched out his tongue, sliding it slowly back and forth between her soft folds, savoring the sweet, musky scent of his soon-to-be-married aunt.

Now and then, he would gently catch her clit between his lips, giving it soft little bites and flicks, before pushing his tongue deeper inside her, sucking gently at the warm love juices that flowed freely.

Under his teasing tongue, Elli’s cheeks flushed deep red. 

She bit her lip hard to hold back her moans, while her soft hand wrapped around his thick, throbbing cock, stroking it slowly and firmly, feeling it grow even harder in her palm.

"Mmm… so hard already," 

She murmured breathlessly. "These thick veins… they’ll rub so nicely against a woman’s walls… and it’s so long… it’ll reach right into the cervix, stretch everything tight… perfect for deep, uterine pleasure."

She played with him a little longer, then bent down into a 69 position and took him into her warm mouth.

His slick cock slid in and out between her lips with wet, lewd "slurp… slurp…" sounds as she sucked him eagerly, tongue swirling around the sensitive head.

Under her skilled mouth, Max couldn’t hold on much longer and tapped her thigh urgently, signaling her to stop.

Elli released him with a soft, wet pop, a thin trail of saliva and precum connecting her lips to his glistening tip as she licked it up slowly.

Before she rose, fluids dripping visibly from her folds — a mix of his saliva and her slick juices trailing down her thighs.

"Now… let auntie really test this big cock with her pussy," she whispered huskily. "Get ready, baby."

Straddling him, she guided the thick head to her dripping cunt with trembling fingers, then slowly sank down.

Her lips parted in a soft "ahh…" as the fat shaft began stretching her open, sliding deeper inch by inch.

The delicious feeling of being slowly filled made her groan low in his throat.

Finally, the blunt head pressed firmly against her cervix, still with a little length left outside.

"You’ve really got a lot…" She breathed, rolling her hips. "The tip is already kissing my cervix… but there’s more to take. Okay, Max… let Aunt try to open her womb for you."

She leaned forward, pressing her full breasts against his chest, and captured his mouth in a deep, hungry kiss.

Her round hips began to move, rising and falling in a steady rhythm, wet sounds filling the room as her juices coated him more with every stroke.

After a few minutes, she angled her ass carefully… pressed down harder… and with a sudden soft "pop" sensation, the swollen glans slipped through the tight ring of her cervix.

"Ahh!!"  

"Ahh!!"  

Both of them gasped at the same moment, overwhelmed by the intense, exquisite feeling.

Elli’s face flushed bright, eyes shining as she smiled down at him and whispered, "Finally… you’re inside auntie’s womb… now we can really enjoy deep, uterine intercourse. Today… you’re allowed to finish inside, baby."

Hearing that, Max’s eyes darkened with hunger as he grabbed her soft, full buttocks with both hands and began thrusting up into her — strong, steady strokes that drove straight into her most secret place, making wet, obscene sounds and splashing her fluids with every movement.

Elli matched his rhythm, her heavy breasts swaying wildly as she rode him, lost in the overwhelming pleasure of being filled so completely.

They continued like that, locked together in their forbidden breeding rhythm, until the pleasure became unbearable.

They reached the peak at the same moment.  

They came together — his thick cock pulsing, pumping rope after hot rope of cum straight into her womb while her walls spasmed and sucked him deeper, milking him for every drop.

"Ha… ha…" Elli panted, collapsing against his chest, stroking her slightly swollen lower belly with a dreamy smile. "So much cum… so thick… perfect breeding load. This is definitely baby-making quality."

Max stayed buried deep, cock still twitching, plugging her cervix so none of his seed could leak out.

"Aunt… did I pass the test?"

She looked down at him with glassy, cock-drunk eyes, slowly licked her lips and purred with a naughty little smile:

"Yes… It’s marvelous. But… I think one sample isn’t quite enough to be sure. 

What do you say we do another round… just to double-check? ♡"

Her eyes were glazed, and she licked her lips with a lewd look, then smiled and said,  "So, Maxxy, let your aunt check your cock again!"

As she spoke, she straddled him once again, wrapping her arms around him, his thick cock still buried balls-deep in her cum-stuffed cunt.

Her fingers trailed lightly down his chest, nails scraping just enough to make him hiss.

"Although you're massive and healthy, and your semen is of the highest quality I've ever seen. But I need to confirm that your production is... consistent.   That you can keep delivering high volumes... even after multiple samples."

She squeezed her inner walls, feeling his shaft twitch inside the hot, sloppy mess he’d already pumped into her womb.

Hearing her words, feeling her flooded womb clench, Max groaned, his hands sliding up to grip her heavy tits, thumbs brushing over stiff nipples.

"You’re still so full of me, Aunt Elli," 

He rasped. "And you’re already asking for more?"

She bit her lower lip, cheeks flushing deeper, and spoke in a trembling tone.

"It’s... important. 

I have to make sure your semen quality remains optimal.  

That it can... flood a woman completely. Over and over."

And started moving, slowly, rolling her hips first, just churning his thick load around inside her. 

"Still so fucking hard," 

She murmured. "Looks like you've got a lot stored in there."

Every little grind made wet, obscene squelching noises as his cum mixed with her slick, pushing out in creamy globs around the base of his shaft and dripping down his heavy balls.

"Oh, my womb is so full of your seeds already? All that hot cum sloshing around in there… sticky and thick… but this greedy pussy wants another load, just to make sure."

She lifted her hips higher this time, letting almost his entire cock slide out until only the swollen head was stretching her dripping entrance, then she slammed back down, taking every inch in one hard, wet drop.

"Ahhn~... still so deep..." 

She sighed, eyes fluttering half-closed.  

"I can feel it pressing right against my womb again... right where it needs to go..."

"Ahh~.. fuck.. still so tight in there.." Max growled, fingers digging into her ass cheeks to help guide her rhythm.

Elli's breath hitched every time she bottomed out. The blunt head kissing the back of her uterus over and over.

Her walls fluttered greedily around him, milking him like they were trying to pull another load out already.

"Ohhh.. yes.. right there.. deeper.. mmmph~.."

Now she was riding him in earnest — lifting high and dropping hard, her fat ass cheeks smacking against his thighs with loud, wet slaps. 

Her heavy tits bounced wildly with every plunge. Each time she bottomed out, another thick rope of his cum got forced out around his cock, running in pearly streaks down his sack and soaking the sheets.

The obscene squelching became... louder now, wetter, more shameless... as she began riding him in steady, rolling waves.

Each upward lift pulled thick strands of cum out around his cock; each downward plunge forced it back inside with a filthy glorp.

Her heavy breasts bounced in time with her rhythm, swaying heavily, nipples tracing little circles in the air.

Max watched, mesmerized, as her swollen pussy lips clung to his shaft... glossy, stretched, coated in creamy white.

"Fuck... look at that greedy cunt, Aunt," he growled. "Leaking my load everywhere and still trying to suck me dry."

Elli whimpered... a soft, needy sound... but kept her "professional" tone, even as it cracked more and more.

"Yes... it’s... necessary... to observe how well you... respond to stimulation... ahh~!"

She started bouncing harder now... ass cheeks clapping against his thighs with wet, rhythmic smacks.  

Her breath came in short, sharp gasps between words.

"I need... to test your... endurance... nngh...  Your ability to... keep going... keep filling... keep breeding..."

Max thrust up to meet her, driving deep, battering that tight ring at the back of her pussy.

"You want me to breed you properly, don’t you, Aunt?" 

"Want your nephew to pump your womb so full you’ll be dripping for days?"

Elli’s head fell back, a long, broken moan spilling from her throat.

"Yes... for science... for... health... oh god... right there...!"

Her pussy made obscene, sucking noises every time she rose, clinging to his shaft like it never wanted to let go.

Max watched mesmerized as her swollen lips stretched wide around his girth. Creamy white streaks of cum coated his cock every time he pulled out. "Fuck, Aunt.. look at that.. your womb's already leaking my cum.. but it's still begging for more.."

Elli's eyes were glassy, cheeks flushed deep red as she bit her lip and nodded frantically. "Yes.. yes.. give Auntie more.. fill me again.. breed me properly this time.. ahhn~!"

Max thrust up harder to meet her downward strokes.. the head battering her cervix with every slam as the lewd slap-slap-slap filled the room again.

She tilted her hips just right, making every thrust batter directly against that tight ring inside her, and soon Elli's moans turned into desperate little cries.

"I'm.. I'm close again. Max..I'm gonna cum on your cock..

He grabbed her hips and yanked her down hard, burying himself to the root, the sudden deep grind against her womb sending her over the edge.

"Ahhh—! Fuck—! Cumming—!"

Her whole body shook violently.. pussy clamped down like a vice around him.. walls spasmed wildly as she gushed around his shaft.

Throwing her head back and screaming as the orgasm ripped through her, cunt spasming, gushing fresh slick all over his cock and balls.

The milking sensation snapped Max's control...and he bucked up hard, burying himself as deep as he could go, and unloaded, blasting thick, hot ropes of his seeds straight past her cervix into her already overflowing womb.

Rope after rope.. painting her walls white.. overflowing.. leaking out around his buried cock in messy rivulets..

"Nngh — take it — take every fucking drop..!

He kept thrusting through his climax, forcing more and more cum deeper until she was whimpering from the sheer fullness, her lower belly visibly rounder, cum leaking out in thick, creamy rivulets around his shaft despite how tight she gripped him.

When the last heavy spurt finally faded, Elli collapsed forward onto him again, trembling, panting.

Her womb felt impossibly full. swollen.. warm as she pressed a shaky hand to her belly and moaned softly..

"So... much... haa... haa... it’s... everywhere inside me..."

The two stayed locked for a while, her cunt still impaled on his cock, gently rocking her hips, letting the last dribbles of cum ooze out around him.

After a long minute, she lifted her head, cheeks flushed dark, eyes glassy with cock-drunk satisfaction… but still burning with hunger.

"Sample two.. complete," 

Elli nuzzled against his neck, lips brushing his skin. 

"But.....I think... for the most accurate results...   we should do one more sample."

Her tongue flicked against his earlobe....

"Just... to be absolutely certain...  

that your production is... truly exceptional."

Max looked at the sweat-filled milf against his chest, feeling his still hard cock twitching inside her womb full of his semen and whispered...

"Unless your balls are already empty…?" At the same time, her cunt clenched, squeezing around his cock as she rolled her hips, feeling him stir and harden again inside her overstuffed, leaking cunt.

Her tongue flicked against his earlobe.

"Because your dirty aunt can keep riding this cock until you can't give me another drop~ ♡💦"

As expected for these two sisters...even though she wasn't as slutty as his stepmom.

Maybe that's because she didn't meet someone who could flip her switch, like now.

"Don't worry Aunt, I've got plenty of cream to give you."

He groaned and then thrust into the muddy, relentlessly pounding and slapping, using his flesh hammer larger than a fist several times to take revenge on the mature womb, pounding it until it was soft and powerless.

"Mmm... hoh... ohhh... ahhh... uuu... ohhh ❤❤～～."

Her head jerked back sharply as she moaned loudly, her fleshy folds clinging to his cock, clamping tightly like scissors, as if she wanted to devour the boy completely!

The sexy bombshell, unable to extricate herself from lust, clung tightly to the young man, riding his cock like a bitch in heat.

Splat, splat!

The completely soaked vulva erotically and stickily rubbed against his crotch, secreting fluids; the sound of his testicles hitting her labia, the sounds of flesh colliding, the subtle rustling of her secretions as he plowed into her.

The young man, holding the beauty's slender waist, continued to thrust forcefully.

Before, it was Elena who rode her handsome nephew to check his cock's virility and semen quality.

But, now, Max was mindlessly sprinting, treating the soft, plump beauty in his lap as a large masturbation cup, ruthlessly pounding her!

Meanwhile, Elena moved her hips to barely match his rhythm, her slutty hole tightly gripping his big cock that was almost at its limit.

In particular, her tender cervix locked his glans, making it feel numb.

"Mmm... hoh... ohhh... ahhh... uuu... ohhh ❤❤～～ Max's cock is so big and hard ❤～～ So big ❤～～ Uu... pu... ohhh... ohhh... ahhh ❤❤❤～～."

While fucking him, she pulled his face to hers and, without hesitation, pressed her dewy, full, fragrant, moist lips against his thick lips. 

That soft, tender, small, red tongue tangled with his large, fleshy tongue.

"Gu-chu... gu-chu ❤～～."

The springy, soft, sticky, thick fleshy tongues coiled around each other, emitting sticky, saliva-filled lewd sounds that echoed throughout the room. 

Releasing even the bone-deep pleasure of receiving seed-planting, pile-driving thrusts through sound, like a hysterical slut.

Her seductively mature, plump buttocks rippled at every powerful impact, turning red as he rammed his cock into her womb.

Every inch of its scorching, fleshy bumps and veins instantly crushed open every bit of weak point, folded flesh within her cunt, which continued to coil as suck on it, expressing the desire to be conquered.

" Ah... ohhh... ohhh... ohhh... ohhh ❤～～ Just like this, fuck, just like this, fuck your slutty aunt to death ❤ My little pussy is going to be ruined, ruined by your big meaty cock ❤ Uu... ohhh... ohhh... ohhh... ohhh ❤❤～～."

As the mating session continued, she turned from a professional doctor to a cock-hungry slut, begging to be bred.

And Max, under his aunt's churning flesh and slutty moans, soon felt himself approaching his limit. 

"Aunt, it's about time to cum. 

My semen... You'd better catch every last drop of it in your slutty womb!"

Hearing his words, Elli looked at his handsome face, listening to his heavy breathing, feeling his throbbing prick plowing her without mercy and shouted the most lustful of screams.

"Mmm... ohhh... ahhh... ohhh ❤❤～～ Good, good, yes ❤ Uu... ah ❤ shoot..your.. semen, shoot it all into my womb! ❤ Gu... uuu... hoh... hoh... ohhh... ahhh... ahhh ❤❤～～."

And just as she did, a powerful wave of pleasure suddenly rushed up to her brain from below!

"I'm cumming too... ❤”

Her body shuddered, cunt spasmed, sending currents throughout her body, under the heavy impacts of his cock at the entrance of her womb, she let out a scream and climaxed....her juices gushing out, spraying on his prick as it plowed into her.

Splashing lewd fluids sprayed messily everywhere. 

"Fuck....take it...you bitch.!!!"

Under the extreme stimulation, Max could no longer hold it anymore and let out a low roar, shoving his cock inside her cervix, before spraying out his scalding seeds, pouring into the in-heat womb.

In yet another climax, Elli's eyes suddenly rolled upward. 

Her pupils spasmed as transparent drool flowed out from her mouth as she opened it wide. 

"Oh so much.... ha……❤"

Amidst the lewd, decadent sound of semen flowing and overflowing, the thick, turbid, white, thick semen squeezed into the full, wantonly, grinding flesh-pot womb, actively nourishing the female cells on the uterine wall that extremely craved his seeds.

"Pop ❤～～"

"So, Aunt, how was my cock?"

"The Besszzt.."

Her eyes rolled, as she murmured something and finally passed out....
