The Mother Who Ravages Her Beloved Daughter with a Black Monster Cock
Rustle-! Rustle-! A woman's hands frantically rummaged through the medicine packets inside the box.
"...!"
She spotted a single sheet of white paper tucked beneath the packets and snatched it up, her eyes widening. 'I've read everything on the instructions... but there has to be something else...!'
Ayoung, the woman who had been scrutinizing the paper from every angle for anything she might have missed, let out a sigh as a folded sheet slipped free.
Flap-...
"Ah...!"
'It wasn't just one sheet...!'
The paper had been so thin that the two sheets had been stuck together, and Ayoung, who had only skimmed the drug's effects, had no way of knowing. Trembling, she picked up the fallen sheet from the floor.
"..."
Unlike the first sheet's description of the drug's effects, this one detailed the [Precautions When Taking].
[First.]
- This drug suppresses erections but does not eliminate sexual desire. After taking it, you must engage in sexual intercourse with the opposite sex to release the pent-up urges.
..She had never once relieved her sexual desire.
[Second.]
- Take only one pill per day, spaced out at regular intervals. *Taking multiple pills in a day may cause unknown side effects.
...Every time her body heated up and her heart raced, she had popped a pill—sometimes five or more in a single day.
[Third.]
- If taking this drug regularly, inform family or close acquaintances, and if abnormal symptoms (binge drinking, binge eating, stress-induced behaviors) appear, stop taking it immediately and monitor your condition.
...She had shown those symptoms but never stopped taking the pills.
"Ah... aaah..."
Ayoung's mouth hung open in a moan-like whimper, her face twisted in terror as she clutched the precautions sheet.
"It doesn't eliminate sexual desire or erections... it's just a delay?"
She had been worried only about her strange behavior so far, but the reality was far more dire.
- Ooooh..! Oooohhh..!! Here it comes, here it comes, here it comes, here it coooomes—Hiiiiiik!!
Even trying to endure just one day had flipped her eyes back, stripping her reason as she masturbated like a monkey in heat. That terrifying lust.
'That kind of lust, piled up for 50 days... inside me right now...'
Ayoung couldn't gauge the sheer volume of urges stacked in her body and felt pure dread.
"Pills...! I need to take the pills...!"
Remembering she hadn't taken her dose today, terror gripped her at the thought of when the lust might explode. She scrambled for the pill box.
"...!"
..But with the packet in hand, Ayoung couldn't bring herself to pull out a pill.
'If I take it, I'll go crazy again.'
She'd snap at her daughter Ara, lash out in irritation, act purely on her urges—lost to madness once more.
"What do I do...! What the hell am I supposed to do?!"
Ayoung shrieked like a madwoman, trembling hands clutching the packets.
Skip the pills, and the pent-up lust unleashes, turning her into a beast ruled by her cock. Take them, and she's a madwoman ruled by desire anyway. The same damn thing.
In that crushing agony.
"R-right! Ask Arthur! If I ask Arthur...!"
Recalling the emergency number from Ben Arthur, her VVIP customer service rep, Ayoung whipped out her phone and dialed.
Riiiing— Riiiing—
The quiet ringtone filled the room.
Crackle-!
Ben Arthur's calm voice came through the smartphone.
"I-it's... well...! I've been taking the erection suppressant pills, and...!"
Calmed slightly by his voice, Ayoung spilled everything in a trembling rush: her symptoms, her condition, how she'd never once relieved her lust while taking the pills.
"I see. That explains why, when I met you, your body's changes seemed faster and more extreme than a typical futanarian's."
"What do I do?! If I take the pills, I'll go crazy again, but if I don't, I'll get erect and...!"
"Please calm down and wait just a moment. I'll contact the manufacturer and get a solution, then call you right back."
"Yes! Please, Arthur... I beg you...!"
Click-!
"Haa..."
As the call ended, Ayoung exhaled deeply, her taut nerves loosening. In her clueless panic, Ben Arthur had become her lifeline.
"Nothing'll happen before Arthur calls back, right...?"
Muttering anxiously, she glanced down at her crotch, hidden beneath her heavy breasts.
'Even if they find a solution... my body's already changed. It won't go back, will it...?'
Shake-...
Her exposed cleavage jiggled from the undone buttons. Outthrust even more voluptuously than before. Ayoung's face fell as she began buttoning up, one by one.
Snap-!
Even buttoned to the collar, her breasts strained the fabric, peeking flesh around the buttons.
"This vulgar body... I've never wanted it..."
Breasts, hips—all of it unfit for a faithful wife upholding her chastity to her late husband. Even if she escaped this state, she sensed this body would linger. Ayoung wanted to cry.
Thump..!
"Ngh...?!"
..But she had no time for sorrow.
Thump..! Thump..! Thump..!
Her heart suddenly pounded wildly.
"Hah...! Haaah... hah...!"
Her breath came in gasps, as after a sprint.
"Nngh..!!"
Her lower abdomen itched deep inside.
'Th-this feeling... no way?!'
Blood rushing to her crotch—Ayoung's eyes bulged.
Thumpthumpthumpthump—!!
Shhhwooo—-..!
But the symptoms didn't weaken; they intensified.
"Hnnngh...!"
Her insides heated up, a line of fire stretching from her belly to her crotch.
'No... already...!'
Ayoung hurriedly hiked her skirt.
Slide-!
She rolled it up, exposing her stocking-clad groin.
Rip-..!
No time to peel them off—she tore them with her hands.
"Hnnngh... please... please... not now...!"
Gazing at her chastity-caged crotch through her cleavage, Ayoung pleaded with the stirring cock inside.
Twitch—! Twitch—! Twitch—!!
Rattle... crack..!!
..But ignoring her, the black cock trapped in the cage swelled with veins from the massive blood rush.
Clunk—! Clunk—! Clunk—!!
"Hiiiik..!!?"
Hardening, it thrashed wildly, as if to shatter its bonds.
'Noooo...!! I said no...!!'
Then came Ayoung's own voice echoing in her mind.
"No... nooo...!! Hiiiuuugh...!!"
The relentless command to mount a female—Ayoung bit her lip, pinching her thighs until they bled to fight the boiling lust, collapsing beside the bed.
Clunk-! Clunk-!
Drip...!!
Then, a snap from inside the chastity cage...
Ping-..!!
The belt buckle securing her waist flew off.
—Splash—!!
The black cloth covering her crotch blasted away, the hidden monster springing free.
"Oooohk..!! Ok...!"
Ayoung's face contorted, lips pursed in a grotesque moan.
Crunch..!! Crunch..!!
Between her legs, the oily black monster cock reared up, curving toward the sky.
"Hiiiik..!!"
Ayoung's mind overflowed with visions of a woman's genitals and the vulgar word for it.
"Hoook...! Hoook...! Pussyyyy..."
Reason on the brink of snapping!
Riiiing—!
The phone rang...
- "Mom... are you tired of me now?"
"...!?"
It rippled through Ayoung's last shred of sanity.
'Snaps out of it... Park Ayoung, you're Ara's mom... Snap out of it...!!'
"Nngh...!!"
Grinding her teeth, she mustered every ounce of strength to quell the lust boiling to her brain.
Crunch—! Crunch—!
'Th-this...! My cock...?!'
Regaining a sliver of sense, her eyes fell on the fully erect monster.
Pulse..!! Pulse..!!
Far longer than before, thicker than ever, the black shaft trembled, its taut glans ballooned to bursting. No need to measure—it had surpassed its old 25cm, hitting around 28cm...
'And this... isn't even fully hard...!?'
Realizing the veins bulging on its surface were mere capillaries, not full erection veins, chills ran down her spine amid the haze.
Riiiing— Riiiing—
The phone kept ringing.
'I have to answer... get the solution...!'
Beep-!
She snatched it with shaking hands and hit accept.
"C-customer, Arthur h-here..."
"Hah...! Ha...!! F-fas... faster... I'm going insane right nooow...!!!"
"Take only half your usual dose. The duration shortens, but no mental side effects."
Clunk—!
She dropped the phone at his words.
Rustle-!
She tore open a packet from the box beside her.
Crunch!
She bit half a pill and swallowed it dry.
"Ahhaaah...! Hah...!! Hah...!!!"
'I endured...!! I have to endure...!!'
The effect wasn't instant. Face flushed crimson, she panted roughly, battling the lust.
Drip... plop.. plop..
Sweat poured like rain over her body.
Throb-! Throb—! Throb-!
Spurt..! Spiiiirt..!
Her balls thrashed to produce semen anew; below, tidal squirts of climax gushed from her pussy slit.
"Ooooh...!! Oooohk...!!"
The lust she endured now rivaled aphrodisiacs for pigs or horses.
Crunch...!
Slide-...
Suddenly, the veins subsided, the cock drooping.
"Hogoook...!!"
Thud-...!
All strength fled her body; Ayoung collapsed fully to the floor.
Sloooow...
Success—the pill tamed her cock!
"Ook... hook..."
But drained of mental and physical stamina, Ayoung lay moaning, immobile for a while.
======
"Ara... Ara, honey."
Ara, dozing in a curl, slowly opened her eyes to the gentle hand stroking her face and the familiar, kind voice by her ear.
"Time to head to work, sweetie?"
'M-Mom...?'
Ayoung's face waking her in the morning—after so long. Her hair still waved in loose curls, her figure sensually outlined by her clothes, but the vibe was utterly unlike yesterday's.
"Can't be late. Come on, up you get?"
Her hair neatly tied to one side. Makeup-free, simple face. No skin shown despite her curves—a plain, modest outfit.
"...Mom?"
"That's right. Your mom."
Ara sat up slowly; Ayoung replied with a gaze full of maternal warmth.
- We're not blood, so be grateful I even bother looking after you!
"Ah..."
A vicious face flashed in Ara's mind—
She turned away from Ayoung, forcing a bright voice.
"N-no need to fuss anymore. I'm grown up now...!"
"Ara..."
"No need to wake me, I'll handle meals and chores. Last night, I realized... I've just been a burden, acting spoiled to you... no, to my big sis...!"
Grab-!
As Ara's voice shook on, Ayoung seized her arm, pulling her close—
Poof-..!
—her ample breasts smothered Ara's face.
'Mom's... scent...?'
Not heavy perfume, but the familiar body odor from every hug.
- Mom... you won't abandon me, right? You'll stay by my side forever?
Shortly after her dad Jo Jinuk passed.
- Of course. I'm your mom—where would I go?
Ara had always slept in Ayoung's bed, cradled in her arms.
Warmth-..!
Bigger now, but the embrace felt just as comforting as ever.
"Ara, I'm sorry... Mom's been sick lately."
"Sick...?"
"Yeah. My heart wasn't like that, but I kept neglecting you, snapping... it was all the illness. What I said yesterday wasn't my real feelings. Can you forgive me just once?"
Ara nodded slowly to Ayoung's sad, earnest plea.
"Thank you. For letting me be your mom again..."
"No... snff... thank you, Mom."
Ara, who had agonized all night over living alone, broke down in Ayoung's arms at her return to normal and gentle tone.
"It's okay. Everything's okay now..."
Ayoung patted her back, soothing until the tears stopped.
"But Mom..."
"Hm?"
"The illness... is it bad? Does it have to do with your body's changes...!"
"Oh, that... yeah."
Ayoung nodded at Ara's serious question.
"Then we gotta go to the hospital! Your daughter's a nurse—ignoring an illness is ridiculous!"
Ayoung could only smile awkwardly at Ara's worried face; she couldn't spill the truth.
"I'm fine. A friend gave me meds, and I'm all better now."
"Good... but if anything's still wrong, promise you won't hide it? I'm your daughter."
"Promise. But you'll be late for work. Breakfast's ready—let's get you prepped, sweetie?"
"Yeah! Mom."
Ara hopped down from the bed with a beaming smile.
"..."
Ayoung watched her daughter's back quietly.
'Sorry, sweetie... for lying.'
She apologized inwardly. Just last night, at dawn.
"Here are the clothes you requested, ma'am."
Ayoung had met Ben Arthur and received outfits like her old style.
"Now, I'll explain your current condition and treatment based on what you've told me."
She learned how to release the lust congealed in her body. Arthur said the urges were too potent and concentrated for masturbation, oral, or other stimulation to work.
The only way: vaginal sex, ejaculating into a womb.
"Take half a pill once daily. Eventually, the buildup will overwhelm it—erections will happen despite the dose, though not perfectly suppressed. But going fully off meds risks rampage, so use the half-dose to stay sane while gradually releasing the lust."
"Our Black Market has many sex slaves. Buy one, and we'll deliver during prep."
Arthur withdrew after mentioning the Black Market's female slaves.
'I'm a woman... sex with a woman...'
Ayoung wanted to deny her reality, but.
"Huh? Why aren't you eating?"
"Waiting for you~ Mom, eat together?"
Ara's smiling face at the table.
"Yeah. Let's eat."
'I have to. To live with Ara.'
Ayoung steeled herself inwardly.
