My Third Sister's Filthy Mouth Hole

After leaving the bandit cave and entering the city, I moved without a moment's rest.

I liquidated every last scrap of gold and treasure I had brought and bought out my third sister Elin's debt in full.

Margaret and Seria, whom I had dragged along and worked like pack mules, were locked up in an inn on the city outskirts.

I rented the basement of an abandoned building on the edge of the city and erected a thick wooden board.

Right in the center of the board I cut a round hole large enough for an adult man's cock.

Wearing a mask over my face, I tore a voice-modulation scroll and crossed my legs.

Creeeak—.

The iron door of the basement swung open and burly enforcers dragged in a trembling Elin.

They flung her onto the floor.

Long years of hard labor had left her looking shabby, yet her distinctive elegant features remained unchanged.

The enforcers left and the iron door slammed shut.

In the dim basement, only Elin and I remained, separated by the board.

Elin curled into herself, eyes wide with terror as she scanned her surroundings.

"W-who are you? They said the creditor had changed, so I came…"

Her voice quivered faintly.

From the other side of the board I spoke in a low, grotesquely distorted voice.

"That's right. I'm your new master. I bought up every last bit of that enormous debt you'll never repay no matter how long you work."

"Th-then… what happens to me now…"

Elin asked in a voice thick with despair.

I smiled wickedly and tapped the hole with my finger.

"Don't worry. I'm going to offer you an excellent way to wipe that debt out in a short time."

"W-what kind of…"

"Look at the wooden board blocking your way. See the hole?"

Elin's gaze locked onto the ominous hole cut dead-center in the board.

Her face drained of color in an instant.

"Satisfy me with your mouth through that hole. Do that and I'll erase that filthy debt."

"W-what kind of horrible thing are you saying! I can't do something like that! Just kill me instead!"

Elin shrieked as if having a fit and scrambled backward.

I snorted.

"Go ahead and die. Sure, dying alone would be nice and easy for you. But who do you think the remaining debt falls on? Your mother Margaret starving back home? Your little sister Seria who'll get sold off to a brothel to pay it? Or maybe even that missing brat Ian."

The moment the names of her family spilled from my lips, Elin's body went rigid.

It was her most fatal weakness.

She had come this far to protect her family; if she gave up now, everything was finished.

"Ah… aah…"

Thick tears began to drip from Elin's eyes.

Her mother Margaret, her sister Seria, and the face of the little brother she had cherished so dearly must have flashed through her mind like a lantern reel.

She bit down hard on her lip.

"If I… if I service you through that hole… will you really erase the debt…"

"Yeah. Fill your belly with my cum and I'll guarantee it."

Elin clenched her fists tight.

Her nails dug into her flesh until blood welled up.

Slowly she sank to her knees and crawled toward the wooden board.

Her knees scraped across the cold cement floor, yet she did not stop.

When she reached the round hole she squeezed her eyes shut.

On the other side of the board I felt my third sister approaching on her knees and dropped my pants.

Ssslick.

I shoved my massive cock roughly through the hole.

From the far side I clearly heard Elin suck in a sharp breath.

"Hup!"

Elin recoiled in horror at the enormous weapon that had suddenly thrust out of the hole.

Veins bulged along its length like a beast's club; it was obscenely huge.

Just imagining it belonged to some filthy old noble made her gorge rise.

But she forced herself to think of her family, stretched out a trembling hand, and gripped the monstrous thing.

"Suck it. Don't use your teeth—lick every inch with your tongue."

I growled like an animal.

Tears of revulsion streaming down her face, Elin opened her mouth wide.

Her hot lips closed around the head.

"Chuuup… chuk…"

Elin's mouth was astonishingly hot and soft.

I closed my eyes and savored the service my third sister was offering.

"Huuup… chuk… juuup…"

Fighting down the urge to gag, Elin stuck out her tongue and licked the glans.

Shame at sucking a filthy man's cock brought fresh tears.

Yet the more she cried, the wetter her mouth became, wrapping tighter around my cock.

I began rocking my hips, roughly violating my sister's mouth-hole.

Thud! Thwack! Thud!

"Uup! Ghk! Uup!"

Every time I thrust, the wooden board rattled.

My massive cock mercilessly slammed deep into Elin's throat.

Unable to breathe, her eyes turned bloodshot and she coughed violently.

"Ghhk! Uegh! Kek!"

I did not stop; I kept swinging my hips.

Beastly, violent piston strokes continued without pause.

My sister's mouth-hole was already nothing more than a vulgar hole for taking my cock.

"Swallow it deeper! Open your throat and take the whole fucking thing!"

Juuuup! Squish! Chook!

Elin felt like she was dying from lack of air, yet she desperately swallowed the shaft.

She sucked so hard her cheeks hollowed.

I accelerated my hips, fucking her mouth like a cunt.

Saliva drooled freely, soaking the floor in front of the board.

Smiling wickedly, I drew up mana.

It was time to properly corrupt this sister.

Through the tip of my cock I sent the tiniest trickle of the Forced Orgasm skill.

Just enough output to stimulate her brain.

Zing!

"Uuup! Huup!"

Elin's body jerked and trembled.

Her pupils began to waver.

This fellatio should have been pure disgust. A horrific punishment of sucking some filthy old man's cock.

But once the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠skill flowed in, a strange pleasure began prickling up her spine.

"Haa… chuuup… chuk… uuup…"

Unconsciously her sucking speed increased.

Without realizing it she stuck her tongue out farther and licked upward.

The sounds spilling from her mouth were shifting from groans of pain into cries of pleasure.

Churrup! Chooook! Chuk!

"Haa… haa… something's weird… I feel weird… uuup…"

Elin pulled off for a moment, panting as she mumbled.

Her eyes were glazed and hazy with pleasure.

I chuckled in my distorted voice.

"What's weird? Is it your body that's weird for getting off while vulgarly sucking cock?"

"N-no! That can't be… hyaaang!"

I suddenly snapped my hips hard, driving the head straight into her uvula.

I raised the concentration of Forced Orgasm another notch and poured it in.

Intense pleasure raced from her throat through her entire body.

Her thighs began to grow wet.

Shame and pleasure mixed together, burning her brain white.

The noble spirit of sacrificing herself for ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her family was gone; all that remained was a vulgar body craving cock like a bitch in heat.

Chuk! Chooook! Churrup! Churruup!

Elin licked and sucked my cock like a madwoman.

Both hands braced against the board, she rocked her head back and forth, forcing the shaft deep into her own throat.

Spit ran down her chin and soaked the valley of her breasts.

"Uuuuup! Kek! Churrup! Hyaaang…"

Beast-like cries kept bursting from her mouth.

To save the family she loved, she was frantically sucking that same family's cock and racing toward climax.

"Fuck, you're sucking like a real slut. You're desperate for cum, aren't you."

I hammered my hips mercilessly, building toward orgasm.

Elin's mouth burned hot, clamping tight around the shaft.

Thwack! Thud! Thud! Juuuup!

Uuuuk! Uuup! Ghhk!

"I… I'm cumming! Swallow every drop! Don't spit a single fucking drop—swallow it all!!"

I roared like a beast and slammed my hips flush against the board.

The head buried deep against the entrance of her esophagus.

Buruuuuurrrk!! ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Squeeeeze!! Gulp! Burut!!

Thick, scalding semen erupted like lava, battering Elin's throat.

An enormous volume of cum kept pumping out, flooding her gullet.

"Hiiiiik!! Uuuuup!! Gulp! Gulp!"

Elin's eyes rolled white as she swallowed the semen.

Even through the pain of her throat being torn open, the pleasure from the skill made her gulp it down greedily.

Milky cum she couldn't swallow in time dribbled from the corners of her mouth.

Her belly pulsed as it accepted the load.

"Cough! Ghhk! Haa… haa… haa…"

When I finally pulled out, Elin collapsed onto the floor, coughing violently.

Her face was a mess of tears, snot, saliva, and semen.

Yet the afterglow of extreme pleasure still lingered thickly on her expression.

Even as she shed tears of despair at the fact that her body had surrendered to such filth, she was rubbing her thighs together.

At that moment translucent status windows began flooding my vision in a frenzy.

The status messages flashed without pause.

The experience bar filled like mad, already on the verge of a level-up.

I looked at Elin beyond the board, still trembling and catching her breath, and smiled wickedly.

I had only just broken in her mouth-hole.

Just thinking about how I would corrupt my third sister made my cock ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠stand rock-hard again.

Keeping the voice-modulation scroll active, I muttered low.

"A mouth alone isn't nearly enough."
