Mom Defiles Her Beloved Daughter with a Black Monster Cock
"It's been a while, ma'am."
Blonde ponytail, black suit, one arm in a cast—Ben Arthur bowed his head in greeting.
"Arthur... what happened to your arm...?"
Ayoung's eyes widened at the sight, prompting the question.
"Pathetically enough... I injured it while escaping."
Arthur shrugged his casted arm once. On closer inspection, it wasn't just the arm; a bandage wrapped around his forehead beneath that golden fringe as well.
About a month ago.
Bang!Bang!Bang!
In the midst of a barrage of gunfire.
"Halt right there!"
Crash—!
Police leaped over cover or smashed right through it in pursuit! Their frames looked as delicate as any slender woman's, but...
Tat-tat-tat—!
Their sprinting speed rivaled motorcycles on the highway, and...
Crunch—!
With unbelievable power from those slim arms, they ripped up nearby metal scraps and concrete chunks to use as shields, charging like berserkers on a battlefield.
All of them were Futanarians.
"Arrest them all!"
"Martial law's in effect—we can just beat the crap out of them!"
To be precise, they were the elite Futanarians handpicked by the state from among their kind.
Bang!Bang!
"Damn it..."
Normally, the side with guns held overwhelming advantage over unarmed foes, and the black market smugglers had always toyed with Korea's police, who couldn't legally carry firearms.
"Got one!"
"One down here too!"
But this new special Futanarian police unit from the National Police Agency had physical abilities bordering on superhuman, rendering guns irrelevant. They breached the factory's firearm barricades—the black market's hideout—in seconds, subduing members one by one.
"Escape through the emergency exit!"
"Yes, boss!"
Of course, the black market had Futanarians too, and their combat experience let them slip from the special unit's grasp.
"A lot happened."
Arthur dismissed the ordeal with a single phrase, impassively scanning his client Ayoung from head to toe.
"Urp...Urp..."
A slovenly face failing to stifle burps, and...
Grrroooowl—!Groooowl—!
A bulging belly straining against her apron, plus...
Crunch—Crunch—
A monstrous cock spewing white steam, erect beyond reason.
"Sorry...! I tried hiding it under my apron, but I ate so much semen my belly bloated up... couldn't conceal it."
"Pardon?"
Even Ben Arthur, ever composed before clients, was struck dumb by Ayoung's words and state.
"Ahem... It seems you've had your share of troubles too, ma'am."
Regaining his wits, Arthur replied...
"Y-yeah..."
...as Ayoung wilted in embarrassment, her cock still out.
"Um...! Since it's been so long, let me pour you some tea!"
"I had some business to discuss anyway. I'd be grateful if you would."
"This way, then!"
Eager to welcome the familiar guest warmly, Ayoung led Arthur to the living room table.
Clink—
"Here you go, Arthur."
She set the steaming tea on the glass table before him, pressing a small tray to her belly. It was the picture of a demure widow.
Throb...!Throb...!
Save for one ruinous detail. No widow sported such a terrifying black monster cock.
"This tea has a fine aroma..."
Ayoung sat opposite, explaining the brew, but...
Hiss—...
'What a pungent stench... Doesn't it bother her?'
Arthur couldn't smell the tea at all over the thick, musky semen reek from Ayoung's cock.
Slurp...
"Fine tea aroma."
"Right?"
"Yes..."
Unable to tell a client her dick stank too badly, Arthur just kept drinking.
"That said, ma'am... Might I measure your cock's size?"
"Wha?!"
"Frankly... it's in an extraordinarily abnormal state right now."
"W-well, yeah."
No denying it—that black monster cock.
"Could I borrow a tape measure? For precision."
"Oh... sure! One sec!"
Ayoung fetched a tape from the bedroom and handed it over.
"I measured it once already, though..."
"Better safe. I'll do it now. Stand there, please."
"Okay..."
Ayoung stood straight; Arthur knelt before the towering erection.
Rustle—
He extended the tape.
"30... no, 31...! Hmm... 32cm."
"Huh? It was 31 before..."
"Size varies with blood flow or physique. Average now seems 32cm."
"I-is that so?"
Mortified at a stranger appraising her absurd cock, Ayoung blushed furiously.
Throb!Throb!
Unlike her shame, the cock—thrilled by the blonde beauty's touch—pulsed its entire massive length shamelessly.
"Now girth... Hard for me to measure alone, ma'am. Hold still?"
"S-sorry...!"
No apology stopped the pumping.
Squeeze—!
"Hah?!"
Arthur wrapped and cinched the tape like taming a savage beast, measuring circumference.
'21cm girth... Incredible.'
Company records showed Alex Parker's erect size: 22cm long, 14cm girth.
Yet the cock Ayoung had nurtured as a Futanarian was 1.5 times bigger—a monstrous impossibility.
'Compared to mine...'
Arthur was a Futanarian too. Erect at 20cm—above average.
Bulge—Sw swell—...
But facing nearly double her own made her shrink instinctively. Genetic superiority?
Tw twitch...Tw twitch...
In her pants, Arthur's white cock shriveled, trembling—not erect.
Squelch—...Squelch—...
Her golden-fuzzed pussy, though, gaped pink, drooling hot nectar at the superior male.
"Hoo..."
Drip...
Her black pants darkened at the crotch, blue eyes half-lidded.
"A-Arthur?"
Flinch!
Ayoung's voice snapped her back.
"S-sorry! Ma'am."
Uncharacteristically stammering an apology, Arthur reached to remove the tape.
Drool...
Semen-mixed precum oozed from Ayoung's cockhead slit, trickling down veiny shaft.
"...!"
As it neared Arthur's close face...
Whoosh—!
Intense male pheromones invaded her nose and mouth.
Gasp—!
"Hnngh—!"
Arthur yanked her hands away, covering her mouth and turning aside.
"A-Arthur!? What's wrong? Is your injury hurting?"
Ayoung crouched closer, face full of innocent worry.
"Is it too hard with one arm...? You okay?"
Haaaah—...
Her semen-laced breath wafted out, nipples tenting her white shirt obscenely.
"Ah..."
Unbidden, her gaze lifted to the greasy black monster aimed her way.
'I want to lick it...'
A fierce urge to lap the precum.
Before she lost control and pounced like a bitch in heat...
"Ma'am!"
Arthur grabbed Ayoung's shoulder, shoving her back!
"Eek?! Y-yes...?"
Ayoung hiccuped in shock.
"P-please... back away from me a moment...!"
"Huh? O-okay."
Arthur's face pale, she retreated.
Huff...! Huff...!
Regaining sanity with deep breaths, Arthur glanced at Ayoung.
Her pure, worried eyes held no clue.
'Ayoung's too soft-hearted. Telling her her cock's pheromones are that aphrodisiac-potent would devastate her.'
"Just dizziness from my head injury. My apologies."
"Oh... Was it because of me pushing you?"
"No. Not at all."
Arthur blamed her wounds, hiding the truth.
"And... your current size: 32cm length, 21cm girth."
"...Unbelievably huge. My thing."
Even plain facts drew a wistful look from Ayoung; Arthur inwardly praised her cover-up.
But one fact couldn't stay hidden—for Ayoung's sake.
"This change... seems from improper erectile suppressant use. A mutation, essentially."
"...Mutation?"
Ayoung blinked in confusion.
"Your cock developed far more than other Futanarians'."
"N-no way!"
She'd hoped others existed like her. But Arthur nailed it: beyond normal Futanarians entirely.
Ayoung keenly felt her body's abnormality.
"Ma'am. Crush this medal, please?"
Amid her shock, Arthur offered a medal stamped with a B.
"This? Looks super tough..."
"If you can, do it."
'No way...'
Ayoung squeezed tentatively.
Creak...
'Wait... it might...?'
Crunch—!
She folded it in half with one hand.
"As expected."
Arthur nodded.
"Requires over 500kg grip strength. Gorillas max at 300kg."
"Whaaat?! No way!"
"Black market reps don't lie, ma'am."
Ayoung stared at the crumpled medal, recalling...
Slap! Slap! Slap! Slap! Slap!
Gripping daughter Ara's ass, pistoning full-force—yet never bruising her.
"No lie...! Even at full power with Ara... no wounds or bruises ever."
"That's next. The mutation likely isn't just yours."
"...!"
Ayoung's eyes widened.
"Ara too...?"
"You may know: partners of Futanarians adapt to the cock that took them."
"Yeah... that's why her ass grew."
Ara's hips recently exceeded 100cm.
"Yes. Likely evolved her buttocks and pussy for your mutant cock. But without relaxant, insertion's now possible."
Indeed. Lately, no injections needed—Ara's entrance stretched, regenerating post-sex.
"From investigating your drug's maker and researchers before coming: her ass didn't just grow."
"Not just that...? Is something wrong with Ara's body?!"
"...Her body probably 'evolved' to accept your off-spec ultra-male cock."
Arthur pointed at Ayoung's member.
"To endure its size and pressure, she gained rapid regeneration, elasticity, flexibility—from relaxant components."
"Y-you mean now... Ara's... my daughter's body...!"
Understanding instantly, Ayoung trembled, shouting.
"Is your personal fucktoy."
"...!"
Thud...
Ayoung's legs buckled; she collapsed.
Beyond taking her virginity—she'd turned her daughter's body into a tool for her monster cock. Vision whited out.
"J-just to confirm... other prostitutes...?"
Voice quavering like she'd cry.
"Probably only your daughter can take it now."
BOOM—!
Ayoung's mind echoed with a massive boulder crashing down.
