The Squirting Big Sister-in-Law
Even Grandmother Liu Ruoshi had begun subtly grooming her as the next generation's family head.
Of course, this was only a temporary role—once Wang Yue matured, the family would pass to him. But Liu Xinru, despite her modest cultivation talent, was a woman of deep responsibility. Even as a placeholder, she was determined to fulfill her duties.
In the martial world, where inter-family marriages were the norm, society had grown far more conservative than the secular realm, reviving ancient customs.
Premarital sex was commonplace in the outside world, dismissed without a second thought. But in the martial world, it was another story entirely.
A Wang family daughter, barely fifteen, had already lost her virginity. In this era of revived traditions, that was no small scandal.
Liu Xinru felt compelled to have a serious talk with Wang Xin'er.
She headed to Wang Xin'er's residence and sent a message.
Soon, Wang Xin'er—now dressed in a cute little nightgown—opened the door and welcomed her in. Though she shared a mother-daughter-like bond with Su Mengqing, both being her brother's lovers stirred inevitable comparisons.
She knew she couldn't compete with her little aunt's sultry allure just yet, so she leaned into cuteness, crafting a style worlds apart. Her aunt always left Brother thrilled yet oddly frustrated during their "little horse pulling a big cart" sessions, right?
Then she'd be his little loli, letting him unleash his manly prowess on her, easing that frustration.
"Big Sis-in-Law, what brings you here so late?" Wang Xin'er asked curiously after ushering her inside.
Liu Xinru's expression turned grave. "Xin'er, who were you with on your trip these past few days?"
"No one special—just Little Aunt, Brother, and the four big sisters: Hong Ling, Bai Yan, Lu Bo, and Zi Yun," Wang Xin'er replied.
"Nonsense!" Liu Xinru's face hardened as she fixed Wang Xin'er with a stern gaze. "You met someone else. I know all about it."
"You found out about that?" Wang Xin'er gasped, her little mouth falling open. She thought the Li Yuan'kui incident had reached Jinling, and Big Sis-in-Law had pieced it together.
"Yes, I know," Liu Xinru pressed, seeing her bluff land. "Who was that man?"
Since it was family, Wang Xin'er saw no point in hiding it. "His name's Li Yuan'kui. A deacon from the Tianhai Adventurers' Association."
"A Tianhai Adventurers' Association deacon?" Liu Xinru blinked in surprise. How had Xin'er crossed paths with someone like that?
But that wasn't the point. "How old was he?"
"Looked mid-thirties, but probably over forty. Why do you care about some dead guy's age, Big Sis-in-Law?" Wang Xin'er tilted her head, puzzled.
"Where is he now?" Liu Xinru continued, sensing the situation worsening. She'd thought if Xin'er had gotten involved with some man and lost her virginity, she could convince Grandmother and Second Aunt to arrange a marriage.
But over forty? Older than Second Aunt? Unthinkable!
"Brother chopped him to death with one swing," Wang Xin'er said casually. "Probably beast shit by now."
"Ch... chopped him?"
Liu Xinru froze, her imagination running wild again. Had that bastard raped Xin'er, prompting Yue'er to kill him? And Xin'er, young and vengeful, just shrugged it off?
Wang Xin'er had no idea Big Sis-in-Law saw her as a tragic rape victim. She huffed, "That creep was gross—couldn't win Little Aunt, so he threatened the four big sisters. Why leave trash like that alive for New Year's?"
"Pursued Little Aunt?" Liu Xinru's mind reeled. What the hell was going on?
"Xin'er, be honest. Did he rape you because Little Aunt rejected him?" Liu Xinru asked.
"Rape me?" Now Wang Xin'er was lost. "What are you even talking about?"
Liu Xinru took a deep breath, her tone solemn. "Xin'er, you don't have to hide from me. I can tell you've lost your virginity. It's not your fault—don't be scared to tell Big Sis-in-Law."
Wang Xin'er shivered. Just thinking of Li Yuan'kui made her skin crawl, and her body was Brother's alone—the thought of anyone imagining her with another man was unbearable. In her panic, she blurted, "It's not like that at all. It was Brother..."
She clamped her mouth shut mid-sentence, eyes wide.
Too late. Liu Xinru's eyes bulged in shock. "You and Yue'er?"
This was worse than rape—a thousand times worse.
Yue'er and Xin'er were twins, born of the same mother!
Incest!
If word got out, the Wang family would be ruined in the martial world.
Realizing her slip, Wang Xin'er backpedaled frantically. "No, of course not! I meant... right, Brother wouldn't let anyone bully his little sister."
Liu Xinru inhaled deeply, forcing calm. "Fine. If not your brother, then how did you lose your virginity?"
"Lose it? I just scratched it by accident while... you know," Wang Xin'er stammered.
"Don't lie. Self-play and a real man feel worlds apart," Liu Xinru said, more convinced than ever. Her heart churned with turmoil.
Though only their big sister-in-law, with the siblings and her daughters so close in age, she'd always treated them like her own children.
Yet they'd committed sibling incest. Heartbroken and lost, she didn't know what to do.
Wang Xin'er, just fifteen, faced her maternal big sister-in-law's piercing scrutiny. Exposed, she had no more lies.
After a moment, Liu Xinru sighed. "Come on. We'll go to Yue'er."
"You're gonna scold him? Big Sis-in-Law, it's not Brother's fault—I seduced him!" Wang Xin'er pleaded.
Liu Xinru sighed inwardly: Xin'er wasn't just chasing thrills; she was hopelessly in love.
All the more reason to stop this sinful affair.
Face dark, she turned and strode out without a word.
Wang Xin'er had no choice but to follow meekly.
With her Earth Palace 6th layer peak cultivation, she could easily subdue her Qi Condensation 5th layer big sister-in-law and scheme with Brother and Little Aunt.
But raised under Big Sis-in-Law's watchful eye, she respected her like an elder—violence never crossed her mind.
The two arrived at Wang Yue's place. Liu Xinru nodded for Wang Xin'er to notify him.
In her presence, Wang Xin'er sent a simple "open the door" message, no tricks.
Liu Xinru wanted surprise—to catch him off-guard and make him confess easier.
But she miscalculated.
Moments later, they saw Wang Yue—buck naked, his raging big dick throbbing as he greeted his little sister.
Simple logic: late-night visit meant she missed him. Even if she wasn't recovered for fucking, he could slip into her little bun pussy and cuddle for basic dual cultivation, easing his ache.
He never imagined company: Big Sis-in-Law Liu Xinru.
With a yelp, he bolted back inside. By the time the stone-faced Liu Xinru and Wang Xin'er entered, he'd thrown on clothes.
Liu Xinru felt shock beyond fury.
She never dreamed a boy Wang Yue's age could pack such a monstrous big dick—that shape, that size. Terrifying. Unforgettable at a glance.
No wonder Xin'er fell for him.
But now wasn't the time. To intimidate the incestuous pair, she kept her face icy, eyeing their unease.
Objectively, if not siblings, they'd be a perfect golden couple. But blood doomed them.
"Do you know you've done wrong?" Liu Xinru demanded coldly.
Wang Yue guessed she'd uncovered him and his sister. "Big Sis-in-Law, it's not Xin'er's fault—mine. I took advantage of her innocence, tricked her into it."
Liu Xinru sighed inwardly, a twinge of envy: taking the blame for each other? True love.
From a lesser Jinling martial family, married for alliances, her bond with her husband was harmonious, even producing two daughters—but more familial than romantic.
She'd never known soul-searing passion.
Breaking such young lovers felt cruel.
But for family and their future, she had to end it.
"End this now. I can pretend it never happened," she urged earnestly. "You can't be together."
"Why not!" Wang Xin'er bristled. She revered Big Sis-in-Law, obeyed her always—except this. Not even Mom or Grandma could sway her.
"Because you're blood siblings from the same womb!" Liu Xinru snapped. "It's against all rites and law—your children would be defective."
"So what? I won't marry. I'll stay as Brother's little sister forever, no kids needed," Wang Xin'er shrugged.
Liu Xinru rubbed her temple—hopeless. With a sigh, "Fine. I can't control you. Grandmother and Second Aunt will decide."
"No!" the siblings cried. Wang Yue begged, "Big Sis-in-Law, please, let us be together."
"Do you grasp the gravity?" Liu Xinru agonized. "If discovered, Wang name destroyed—you two shunned by the world!"
"As long as you keep quiet, who'll know?" Wang Xin'er said.
"No secret holds forever. Stop now, or it'll leak," Liu Xinru warned.
"So you're dead set on splitting us?" Wang Xin'er's tone chilled.
"It's for your good," Liu Xinru sighed.
"You forced my hand!" Wang Xin'er gritted, striking like lightning—sealing eight major acupoints, immobilizing her.
Liu Xinru gasped. Xin'er matched her cultivation—how was she suddenly so strong?
"What are you doing?" Liu Xinru demanded—her speech untouched.
"Can't let Grandma or Mom know—they'd split us," Wang Xin'er ignored her, turning to Wang Yue. "Bro, fuck her. Conquer her with your big dick—she won't try splitting us then."
"Huh?" Shock hit both Liu Xinru and Wang Yue.
He knew his sister got bold at night, but this? Urging him to rape Big Sis-in-Law?
Liu Xinru, Chen Rong's daughter-in-law, was far steelier. She snorted, "Pulling me down too? Useless—kill me now, or for family and you two, I'll stop this incest even if it destroys me!"
Wang Xin'er giggled. "Big Sis-in-Law, tough talk's pointless. Try Brother's big dick—you'll worship it. Fucking him feels heavenly and boosts cultivation. This is for your good."
To Wang Yue: "Bro, your move. I'm out."
She slipped away, thoughtfully locking the door.
Wang Yue stared helplessly at her retreating figure. How did she dream up this?
But realistically? No other way. Big Sis-in-Law wasn't like Aunt—strong-willed, family-first. Unconquered, she'd report to Grandma and Mom.
Wang Yue wasn't indecisive. Sister forced the point of no return—might as well go all in.
"Sorry, Big Sis-in-Law." Apologizing, he scooped her rigid form, carrying her to the bedroom. Aunt's like this, now you—mother- and daughter-in-law both cursed meeting me.
Only way to make amends: drown them in pleasure.
In the bedroom, he laid her flat on the bed.
She stared coldly, silent.
Guilt stirred— she'd raised him. That reverence twisted into forbidden thrill.
Focused on Xin'er earlier, she still wore her daytime training clothes.
Loose fit hid curves usually, but her explosive figure made them tease: full breasts and hips peeking, adding exotic allure.
Her massive tits strained the fabric flat against her, monumental. Wang Yue groped them through her clothes.
"So big, so soft, so bouncy—perfect feel!" As he kneaded, he praised, "Big Sis-in-Law, I've craved these tits forever. Watching them bounce in the training yard, I dreamed of grabbing, squeezing, sucking—titfucking my dick between them."
"Pervert!" Liu Xinru spat, furious and humiliated. Yet his hands sent tingling pleasure through her breasts, sinfully good.
"If lusting after beauties makes perverts, most men qualify," Wang Yue grinned. "You're gorgeous, sexy—a hot-blooded guy's gotta wanna watch and fuck you."
"I'm your big sis-in-law, your cousin's wife, watched you grow—how could you?" Liu Xinru raged, more grieved than angry.
Wang family's—and Jinling three clans'—sole male heir. She hated seeing him corrupted.
But Wang Yue was resolute. Releasing her changed nothing.
Only fuck her senseless till conquered.
No more talk—he mauled her tits relentlessly.
Soon, clothes dulled it. He stripped her top, yanked down her modest bra.
Her snowy giants sprang free, quivering.
His guesses confirmed: not smaller than Little Aunt's, and on her shorter frame, huger.
Large areolas—five centimeters wide, red-brown caps—big nipples like dates, erect from his touch.
Not Little Aunt's dainty pink prettiness, but ripe, mature seduction.
Wang Yue dove in, suckling one like a babe, slurping loudly.
Liu Xinru clenched her teeth, fighting the bliss, clinging to anger and dismay.
Only after swelling them further did he rise, stripping naked. Straddling her chest, he teased her saliva-slick nipples with his glans.
Seeing his dick toy her tits, Liu Xinru flushed with fresh shame, eyes slamming shut.
But the hot, hard prods on her nipples pierced her defenses.
Soon, he sank lower, nestling his cock in her deep cleavage, squeezing her tits around it.
Thrusting, his length shuttled her valley—glans nudging her delicate chin each forward stroke.
Eyes closed, she felt it all: immense, rigid, scorching...
Thirty-plus years, she'd never imagined a cock so huge.
From an underage boy? The contrast shocked deeper.
Titfucks lacked raw pleasure—pure kink.
Her stoic face bored him quick.
He abandoned her torso, stripping pants, panties, shoes, socks.
Now, her voluptuous nude lay bare.
First word: plump.
Not fat—plush at worst. "Fat" concentrated in tits, ass, thighs.
Thighs not Little Aunt's endless, sister's slim, or Yan-Mom/Aunt's sleek—but rounder, sexier.
Overall, meaty sensuality.
Less "artistic" than Little Aunt, but peak "fuckable."
Admiring, he spread her lush legs, eyeing the prize.
Opposite Little Aunt/sister's bald white tigers, hers was a jungle: thick bush blanketing mound, flanking deep-red lips.
First "hairy saucy pussy"—curiosity piqued. He parted the forest, probing her crimson slit.
Her mature cunt clenched instinctively, oozing crystal nectar, wetting his fingers.
Books said hairy or bald women hornier—maybe true.
Wang Yue smirked inwardly, aloud: "Feeling it, Big Sis-in-Law?"
She stayed shut-eyed, breaths quickening.
No expert, but basics he knew: break her iron will first—shatter defenses, induce collapse.
Plan: demolish shame, unleash lust, then overwhelm with stamina.
Finger-dipping her fresh slick, he waved it before her face. "See this, Big Sis-in-Law?"
Eyes sealed, silent.
Shrugging off the pussy-juice show, he ground his cock along her slit.
Her body betrayed her quick—fingers alone juiced her; glans friction flooded.
Slick coated his crown fast.
"Taste yourself, Big Sis-in-Law." Grinning, he sidled to her head, smearing her lips with her own wetness, then prying with his glans.
Pinching cheeks forced her mouth open.
He pressed—half her-slicked glans invaded.
First cock ever—coated in her juices. Humiliation peaked; she'd bite if able, ruin the beast.
Her crimson fury thrilled him: Working!
But newbie tricks limited—dick-in-mouth her peak.
Strength over finesse: his big dick's power he trusted.
Back between thighs, tip kissing slit: "Gonna fuck you now, Big Sis-in-Law."
Words futile, she knew—stayed mute.
Deep down? Flicker of craving his monster's plunge.
Shame burned, but uncontrollable—cunt winked, spurting more.
"Can't wait, huh? Don't worry—little bro's coming." He eased in slow, wary of pain from past rushes.
Full glans in—no agony.
Even stranger: looser than Little Aunt/sister (virgins), Yan-Mom/Aunt.
For his size, still snug—but fact remained.
Why?
Three years celibate—should be tighter.
No other men: loyal, fortress-secure.
Only: frequent toys—big ones.
Prim proper by day, repressed slut by night!
Confidence surged. Hips snapped—schlick!—half-buried.
"Ahh...!" Liu Xinru yelped, pained.
Looser than Mom-in-Law's, but his girth wrecked—deep thrust agony.
Pain faded to impossible fullness.
Never so stuffed—save birthing daughters.
Subtle twitches sparked bliss; willpower alone held her.
Wang Yue paused adaptation, then pumped steady.
"How's my big dick, Big Sis-in-Law? Feel good?" He grinned mid-thrust.
Brows furrowed, eyes shut—no quarter.
"Silent treatment? Your saucy pussy loves it—clenching, begging me stay."
Torture: pure ecstasy, but she fought, clamping moans.
Pain easy; orgasmic tide? Hellish.
Childbirth paled; she'd crack without iron will.
Moans held—body not. Hundreds strokes in, she quivered violently.
He sensed: few more, or flower-heart grind, she'd shatter.
But he yanked out fully.
Her ass bucked vainly after him.
Edged denial—madness-inducing.
Paralyzed, no self-relief.
Waited her peak ebb, re-entered, hammered.
Edge again—pulled.
Twice teased, she broke. Lust consumed—shame, morals? Bullshit. Need to cum!
Third edge, as he withdrew: eyes flew open. "Please! Don't pull out!"
Glans barely in, he froze—no re-thrust. "Why? Don't you hate me fucking you?"
"No! Love it—so much!" High tide trumped all; truth spilled.
"Good girl. My big dick wrecking your saucy pussy good?"
"Yes! Not just pussy—whole body bliss from your big dick!" Desperate: "Little bro, fuck me! I'll go mad!"
Satisfied, he gripped her plump ass, slamming home—heavier, deeper, glans battering womb near-breach.
"Little bro, I'm dying... dying...!" She convulsed, ass grinding up, cunt vise-gripping as she gushed.
Her urethra flared—a clear jet sprayed, drenching his face, hair, chest.
Mid her spasming saucy pussy creampie, Wang Yue froze: She pissed? Nah.
Heavenly Origin senses: no urine tang.
Tide!
Rare trait—one in ten.
Jackpot!
No physical boost, but watching her squirt? Soul-shattering conquest.
Resting, he unsealed her points.
Yet she lay limp, despair crashing.
Here to stop sibling sin, righteous guardian.
But she'd begged him to fuck her for climax!
