Acquiring My Personal Onahole
*Slurp slurp chu-ru-lup♥* The sound of wet sucking echoed.
A woman, intimately kissing and licking the shaft as if savoring a familiar treat.
Yoon Seoha watched her sister with a smirk.
"You're pretty familiar with it."
"Mmm. I've done it a lot... ♥ You wouldn't know, Seoha...?"
She planted a kiss on the glans, then dragged her tongue long and slow along the pillar of the cock. She gathered saliva in her mouth and let it drip down, smearing it over the entire length with her palm.
A squelching sound followed, and the suction on the glans intensified.
"Nngh."
"Gonna cum?"
"Yeah."
"Then cum for me♥ Fill my mouth up... ♥"
Thick semen, almost like custard cream, poured out. Yoon Seoyoon swallowed it greedily, her eyes glazing over slightly as she looked up at Yoon Seoha.
"Baa~♥"
"Ha... seriously."
"Phew, our little sis... your cock's gotten huge... and the load's bigger too."
"That's why I'm asking—how the hell do you know that?"
"There's ways♥"
Yoon Seoyoon grinned mischievously and lay back on the bed. She spread her legs wide, exposing her aroused, dripping pussy.
A pretty pink slit, slightly plump. Yoon Seoha's cock pressed against it.
"Ah... ♥"
"...You're not a virgin?"
"Nng. Disappointed?"
"A little...?"
Yoon Seoyoon chuckled at Seoha's words.
"Don't worry. Before, now, and from here on—my pussy's only for you. Experience count: one. Only you've ever used it♥"
"Huh? What does that—"
"Shh. Don't overthink it. Just fuck me already. This is the first time I'm getting it like this♥"
Yoon Seoyoon's cryptic words puzzled Seoha, but the overwhelming pleasure surging through her cock drowned out any questions.
"Hngh, haaht, kkuuup♥"
"Hng—!"
"Kk, heek♥ O, oowook♥"
It felt different from BB or the other bitches. Not a tight squeeze, but a cozy embrace.
"Ngh, hieeek♥"
"Haa, hngh."
"Hoo, hoooook♥"
Seoha moved her hips slowly, deliberately. For some reason, she didn't feel like pounding away roughly.
She wanted to bury her cock deep in that snug pussy and savor the lazy rhythm. The velvety walls hugged her warmly, and her cervix parted wide, cradling the glans tenderly.
"Huuuuk♥ Kk, hiiik♥"
Vulgar moans.
Seoha thrust deep, letting out a short groan.
Objectively, it was inferior to BB's pussy. No tightness to speak of, less chewiness, a clear downgrade in every way.
But there was something.
A profound satisfaction that filled her from the depths of her soul—something BB lacked.
If BB's pussy was a luxury suite in a five-star hotel, Yoon Seoyoon's was like coming home. A subtle comfort no hotel could match.
"C-cock♥ Lil sis's cock is the beeeest♥"
"Feels good?"
"Y-yesss! So gooood♥ Ah, aaaah♥ Goooood♥"
"Yeah? I like your pussy too, sis."
"Haaaaah?! Kk, hiiiiik♥"
The pussy clenched and writhed. Sticky juices soaked the sheets, and the cervix twitched, pulling the cock deeper inside.
They said sisters were mom-made onaholes. It was true.
"Gotta thank Mom."
For this killer body and for birthing such a perfect onahole.
"Take it."
"Hnghk, kyuuuuwuuut♥"
Seoha pinned down the womb, unleashing her load.
Thick semen flooded the uterus, over and over. The bloated womb, crushed by the cock, spat it back out—only to be refilled again.
Dozens of times.
The womb turned ragged, the pussy limp and slack.
Strength drained from Yoon Seoyoon's body, the light fading from her eyes.
A pleasure-induced blackout. The body's failsafe to prevent total brain meltdown from overwhelming ecstasy.
"Hngh."
*Pop*—Seoha pulled out with a wet sound and caught her breath.
She grabbed her sister's legs, hoisting them up.
The gaping pussy could easily fit a fist. She aimed her cock and—
"Hnght!"

—slammed down.
"Kkiheeuk?!"
Mating press. Or breeding press.
Thick cum from her stomach bubbled out her mouth. Her eyelids fluttered, pupils flickering.
Tiny sparks burst in those pretty brown eyes.
"Wha, heh? Heek...?"
"Sleep well? Sis."
"Ah, uh? Uuugh... ♥"
"That's no good. Who gave you permission to pass out?"
A sweet voice whispered into Yoon Seoyoon's ear.
It melted her brain. The liquefied thoughts spilled out as tears, snot, drool, and pussy juice.
Something inside shattered irreparably. Already cracked and barely holding together, it crumbled to dust.
Wha... what am... I... do...ing?
What had happened?
Moans poured from her lips, her body convulsing in addiction. Thoughts fragmented, burning away unfinished.
Ah... right. I'm... an onahole...?
*Thud thud thud, squelch squelch squelch.* Vulgar sounds rang in her ears, mixed with her own slutty moans.
...Heh, hehehe...
Pleasure was a drug.
Harmless to the body, but it wrecked the mind.
"C-cock... ♥"
Her eyes lost focus, drowned in bliss.
She tried to remember who she was, but even that felt like too much effort.
She could only surrender to the overwhelming waves.
"Like cock?"
"L-love it♥"
"Good. 'Cause I'm expensive."
"Ex-pensive?"
"Yeah. Pricey."
Seoha grinned.
"Even if you spent your whole life as my personal onahole, you couldn't pay it off."
"Hee, hiiik... N-nooo..."
"No?"
"N-nngh... Nooo..."
Seoha pressed on the womb and repeated.
"For real? When it feels this good?"
"Wha...? F-feels... gooood..."
"Then why not?"
"Uh... wha...? Th-that's... uh..."
Semen flooded the womb.
Thick, potent seed that would impregnate without fail—pumping her full.
*Blub blub blub.* The violent gush echoed in her brain.
"For real?"
"Uh, uhhh..."
"Be my personal onahole, and it'd feel great, right?"
"F-feel... great...?"
"Yeah."
Seoha stared straight into her sister's eyes.
"Feel great."
"...Feel... greaaat?! Kk, hiiik♥"
"You'll do it?"
"Y-yes, yesss♥♥♥ I'll dooo it?! Hng, hiiioook♥"
Yoon Seoyoon nodded amid her vulgar cries. Seeing it, Seoha laughed exaggeratedly and cheered.
"Yay! I'm so happy, sis!"
"Hng, kkooook♥"
"Here, a kiss for you!"
"Kk, hiiungbup♥ Mmwah, hiiubup♥"
Sloppy kissing sounds filled the air as Seoha pumped another load inside.

Late evening.
After extending the day-use several times, Seoha finally switched to an overnight stay and made a call.
Seoha glanced down as she spoke.

"Anyway, hanging up."
