No Refunds on Futanari
Anyway, the money's already paid... what can you do?
Chae Yu-na loved her sister, Chae Ye-na.
She was an idiot, scatterbrained, gullible enough to fall for scams, couldn't earn a dime but spent like it grew on trees—yet Yu-na loved her anyway.
Because she was pretty.
Of course, Yu-na loved herself too, with her face that was an exact match for that pretty one.
But unnie's got bigger tits, at least.
So she put up with it.
When Ye-na donated 200,000 won to some religious group Yu-na had never even heard of, or when she invested in a coin named after some random seaweed that wasn't even a celebrity pet, or when she got hauled into the police station for leaving sexual harassment comments on female idols—Yu-na covered for her every time.
She's kind, at heart. A bit dumb and clueless, sure, but kind. And with tits that big, of course she's airheaded. Yu-na argued her case passionately.
"But this... this is too much."
Staring down at her sister, whose body was cooling off, Yu-na muttered under her breath.
Two million won.
A third of what Yu-na earned in a month.
Rent, food, clothes, games, savings—money had a million places to go, and yet she'd blown it all on a one-time brothel service.
At least pick the one with the big tits!
No, wait—wasn't it random?
Yeah, probably! Random pick, so of course someone flat-chested showed up!
Unnie's always had rotten luck anyway!!
...Hah. For real.
Yu-na turned her head and eyed the woman named Seo-ha Yoon from the service.
Futanari, right...?
This was her first time seeing one up close.
She'd learned about them in school, read about them online—knew the facts—but seeing it in person hit different. Way different.
She's that gorgeous... and she's packing?
Seo-ha was beautiful.
Honestly, if it weren't for the chest—or rather, the lack of it—Yu-na might've begged her to marry right then.
...Money's spent, though.
No refunds, probably.
Nothing to be done.
Yeah.
Nothing for it.
"Um..."

Seo-ha Yoon gazed at Chae Yu-na, who wore a faint smile.
The girl was wiping something red off her knuckles onto her clothes, stepping closer one foot at a time. Seo-ha wanted nothing more than to bolt backward.
She's scary...
Hiding that thought as best she could, Seo-ha faced her with the biggest smile she could muster.
"Thaaat's... the fee's already paid, right?"
"Yeah, it is."
"...S-So, ending it here would just be wasting money... right?"
"Y-Yeah...?"
At Seo-ha's response, Yu-na grinned dopily and slowly stripped off her clothes.
Her black tee hit the floor with a soft thud. No bra—her small breasts were right there, bare and perky in a cute, petite way that drew Seo-ha's eyes.
"Mm."
Seo-ha took a step forward.
A height difference of over a head. Looking down at her, Seo-ha smiled with her eyes.
They curved into crescent moons, her brown irises taking in every inch.
"Ah..."
A soft gasp.
Seo-ha stripped off her own underwear, standing naked before her. Their pale skin glowed in the light.
"...F-Fuck."
Yu-na's piercing stare fixed on Seo-ha's body—locked onto the massive cock. Thick as a forearm, no exaggeration. It swelled, rising upward, and Yu-na swallowed hard.
"...Ah."
"Kiss first?"
"...Y-Yeah."
Yu-na went up on tiptoes, pressing her lips to Seo-ha's.

Not soft or lover-like—just devouring. Tongues tangled sticky and fierce; Yu-na's hands twitched.
Her fingers dug into Seo-ha's firm skin.
"Ngh, hnnngh...!"
Her juices dripped to the floor.
Heart pounding, breaths ragged. Her deep green eyes trembled up at Seo-ha.
Ah...
Dangerous.
Her instincts screamed it. This was too far—some primal instinct howled a warning.
B-But...
Should she stop?
Two million won.
A third of her monthly pay. With savings, it was two-thirds of her living expenses.
Should she stop?
But after dropping that much cash, wasn't getting your money's worth the right call?
Was that reason talking... or...?
Ah. Head hurts.
Thud—her body was shoved.
Pushed onto the bed, Seo-ha looked up at the trembling girl above her.
Ah.
Thud—the massive cock slapped down on her stomach.
From lower belly past navel to solar plexus. Would that even fit? And if it did, what then? The thoughts clashed, headache blooming.
"I-It won't fit..."
"It's fine. It always does."
"B-But just in case..."
"I've fit it in girls even tighter than your sister."
A wet squelch.
The huge glans pressed against her narrow slit.
Rubbing between thick labia, the girthy shaft began sliding in slow.
"A-Ahh, ooooh?!"
Her body shuddered, convulsing.
Juices squirted out in a psshhh.
Something precious shattered inside.
"Ah, u-ugh...!"
"Mm. A virgin, huh?"
"A-Ahh, ooooh...!"
"And you're cumming this hard already. Pervert. Just like your sister♥"
Squelchhh♥
Her pussy stretched by force.
Breaking, tearing, overwhelming pleasure crashing in. Her brain rattled. Eyes rolled back, whites showing. A voice no girl should make poured from her lips.
Her lower belly bulged out—the motion visible front to back. Seo-ha's big hand gripped the protrusion.
"K-Kyaaaah?! Kiiiii♥"
"Nng? This your womb?"
"Kh, h-hooooh?! Kyahuuu♥"
"Yup, womb. Take it♥"
A guttural wail.
Seo-ha slammed her hips, crushing the womb relentlessly.
Like jacking off. No matter the screams or moans, Seo-ha pistoned mechanically.
It felt good.
But that was it.
"Hah."
"Khhnnngh♥♥"
Just an onahole that moaned and climaxed with every thrust. Better than silicone from the store, sure—but barely.
Seo-ha endured the creeping boredom, hips moving.
Pussy clenched tight, womb hugged the glans, refusing escape.
Same as always.
This girl was no different.
"Nngh."
Squelch—♥ Squelch♥ Squelchhh—♥
Emotionless pistoning continued.
Moans, dripping juices, spurting cum. It felt good, satisfying—but something was missing.
"Kh, hi, hnnngh...♥"
Seo-ha slowly pulled out.
"Hoo."
Exhaling, she sat on the bed's edge.
The sister trembled hard. Seo-ha smacked her ass, watching the reaction.
Shaking, squirting everywhere. The mess of fluids drew a hollow chuckle.
"Yaaawn..."
Four hours since sex started. Four more till the basic eight-hour service ended.
Boring.
Had any client ever bored her like this?
Come to think of it, that married woman last time was the same.
She could've filled 48 hours, but didn't. Or rather, hadn't bothered.
"Kinda dull."
Seo-ha muttered softly.
She patted the sister's ass, rousing her from her faint.
"U-Ugh...?"
"Gotta clean up."
"...Y-Yeah♥"
Twitching, she slid off the bed.
Sitting in the pooled juices, she carefully kissed the cock.
Seo-ha absently stroked her head.

"Like a puppy."
Smack smack, tentative kisses cleaning cum and juices with her tongue—sneaking tastes now and then. Total dog vibes.
"Ehehe..."
Petting made her squirm happily, face melting into a dopey grin. Seo-ha couldn't help smiling.
Not the smile for lovers—for pets, like a dog or cat.
"Nngh."
Hand slid lower from her head.
Cheek to chin.
Gently scratching under the chin, Seo-ha murmured.
"Good girl?"
"Y-Yes! So good...♥"
"Mm."
Easy as always.
Wreck the womb a bit, pet the head, and they fold.
"Little sis."
"Y-Yes?"
"Bark."
At Seo-ha's command, Yu-na froze in confusion.
Eyes wide, darting side to side, parsing the meaning.
But not for long.
"W-Woof!"
Barking like a dog in seconds.
Seo-ha petted her head, watching.
"Good girl."
"Woof, woof!"
"Pfft. That's right."
