Hikikomori Me and My Perfect Sister - Onahole Rampage Masturbation Begins!
"This one's shaped like an ass... and this one's a one-hand pussy?"
My sister pulled each onahole out one by one from the open chair and placed them on the glass table in front of the sofa.
....!
Every time one was revealed, I wanted to crawl into a hole and die. Even a total virgin like me had sexual urges, and I'd been satisfying them with these. I'd made sure to receive the packages when she wasn't home to avoid getting caught, and just in case, I'd even bought a sofa-chair-style lockbox to store them safely in my room...!
"Lewd sister's big ass... Sultry big sis's thick, plump pussy..."
And she even knew the product names!?
Of course, the already-opened onaholes didn't have labels, and I'd thrown out all the boxes to save space. Even if she'd absorbed my memories, how could she recite the full names of products I barely remembered myself...?
"They're all 'sister'-themed toys, huh?"
That meant she'd known exactly what I'd ordered from the start.
Squish—
She picked up the pink "Sultry Big Sis's Thick Plump Pussy" one-handed onahole again, bringing it right up to her face.
"...I'm a little hurt. You should've just told me instead of using these. I would've taken care of everything for you."
Squeeze—!!
She gripped it hard, crushing the onahole in her fist. Even with its high-elasticity silicone, the combined strength of a woman and a man made it seem like it might burst any second.
No... honestly, who cares if the onahole breaks at this point.
"..."
The real problem was the blank look in her eyes—like after the onahole, I'd be next in that grip.
Clang—!
But she let it go, propping her face with one hand as she smiled.
"Still, I get it. You're at that age, Jinseong, so you needed somewhere to vent your urges. And... I'm kinda glad these exist."
She spoke with that same gentle face and voice as before...
Squish—!
"Now I get to use your dick on the toys you used?"
...What?
I froze at her bright smile. Use my dick on my onaholes?
Twitch..! Twitch..!
Yeah... it was possible. Since I'd become her cock, she had a dick to shove into them.
But why would she want to use my old onaholes? Just because she grew a dick and wanted bigger pleasure?
"Hehe..."
Throb..!
My body—our lower half—was rock-hard, so yeah, lust was part of it.
"Haaah... I'm gonna use the onaholes you jerked off with and make your experiences mine."
It wasn't just lust. Did she want my body, memories... and even my experiences!?
How deep did her obsession with me go? Her love—call it what you want—felt bottomless, and it terrified me more than ever.
Squiiiish—..! ..Ah.
A cold splash hit my head like ice water, snapping me alert as I watched her again.
Drip... Sticky..
No way—is that gel? Love gel, the lube. Thick, transparent lotion-like stuff essential for onaholes since they dry out otherwise.
Squelch—... Squelch—..
She wasn't applying it inside the onahole... she was pouring it all over my shaft.
Did she not know how to use them? No, impossible. She'd absorbed all my memories, including how I'd used them a million times.
Thud—.. Sticky—
She'd emptied a whole bottle and tossed it aside.
Squelch— Squelch— Squelch—
One hand stroked my slick shaft.
Squish.. Squish..
The other grabbed the big sis pussy onahole.
Psssh—
She squeezed lightly to vent the air inside.
That's when I realized she'd gotten all my onahole memories. To make them feel better, you squeeze out the air first...
Schlup—...
"Nngh...!!"
—Sluuuuurp—..!!
She pushed my glans first into the thick pussy-shaped entrance.
Squiiiish..! Glorp—..!
"Ahhat—! The onahole you used is sticking so tight to my Jinseong... haaang..!"
With the vacuum seal, the internal nubs and gimmicks clung perfectly to my shaft.
"Ohhot—.. Hoook.. This is it..!"
Squish— Squish—
She gripped and released the squishy surface repeatedly, legs spread wide, thighs trembling.
"Oook..! Hoooot...!"
Just kneading it was huge for her new-to-dick body—she stared wide-eyed, letting out vulgar hoots.
..Guhk..! Uuooo—!!!
No... I wasn't in any position to casually observe her reactions.
Glorp— Glorp— Glorp—
Her grip made the thick silicone pussy walls massage my entire shaft up and down.
....I-I'm sensitive right now!! Don't squeeze so hard..!!
Glorp—! Glorp—! Pffft..!!
The meaty, squishy masses pressed against my hypersensitive, fever-hot skin.
...Uooooht—!!
True to its name "Big Sis's Thick Pussy," it felt like being hugged by a gentle older woman's soft naked body—pure comfort.
"Nnght..! I feel it.. haaang! You're feeling good too, right Jinseong? If you like it, I love it..! But.. but.. getting off to some other bitch's pussy..!"
Schlup—Shluck..!!
"That's NOT allowed!!"
She glared, yanking the onahole from my base up to just under the glans in one go.
...Uhheeeek—!!
It was like someone grabbed my head, yanked it up, and stabbed needles everywhere—a jolt of ecstasy.
"Cumming to any pussy but mine!! I can't forgive that..! Can't forgive it..!!!"
Schluckschluckschluckschluck—!
No mercy for me—she pistoned the onahole up and down furiously.
Squelch-squelch-squelch-squelch—!!!!
...Sis, please stop—!! Too fast!! This pleasure's gonna drive me insane!!
I begged even knowing she couldn't hear me.
Glorpglorpglorpglorp..!!!
Before, it was cozy marshmallow softness. Now? It was like throbbing painfully hard on mountains of tits and ass—overwhelming bliss I couldn't handle.
Crunch..!!
My shaft inside was at its limit—veins bulging, throbbing veins everywhere.
Squeeze— Gloooorp..!! Bulge—! Bulge—!!
The onahole, once snug, couldn't handle our combined erection—every upward stroke made my glans bulge out visibly.
"I'm cummiiiing—! CUMMING—!!! With your onahole, I'm gonna cuuum— nghoooook..!!!"
Slap—!
She thrust her hips forward, arching her back like a bow.
Gush— Spluuuurt— Bluuuurb—! Blubblub....!!!!
Her male orgasm erupted deep into the onahole.
Gurgle—!! —Gushgushgush—!!
The semen pressure was insane—the end, bulging glans-shaped, bubbled and boiled with white fluid like a condom overflowing.
...Guhk.. Huhk..!
I figured she'd rest after that ridiculous load, but...
Crunch..! Crunch..!
...Wh-what?! Why's it still hard..!
My dick wasn't dying—it was getting harder, throbbing stronger inside.
As I reeled from the stretching pain...
"Feels too good... so I can't forgive you. Using such a good hole without me— aaah..!!"
Her face twisted in rage.
"Kang Jinseong!!! Kang Jinseong! Kang Jinseong! Kang Jinseong!!!"
She screamed my name hysterically...
Schluck-schluck-schluck-schluck-schluck-
...Kaaaaah!!!
Friction heat burned my skin as she shook the onahole at hyperspeed.
Bloooorp—!! Bloooort—!!!
Incredibly, even as she stroked fast, my erection held—and I kept cumming.
"Kang Jinseeeeong—!! How could you leave me!!!"
Proof of her lost reason—and that she wasn't checking her body.
..I'm dying..! Gonna die!! Either drained dry or skinned alive!!
Snap—-!
The semen-swollen baseball-sized end tore open.
Pop..!
A tiny hole formed, and—
Spluuuurt—!!!! Bloooort—!!!
"...!"
The backed-up cum blasted out, startling her into stopping.
"Ah..."
Thud—..!
Post-orgasm crash hit—pupils rolled up, she staggered back onto the sofa.
Squish—.. Thump..!
The torn onahole popped off me and rolled across the floor.
..Huhk.. Hek..!
Somehow, I stayed conscious through that torrent of pleasure and pain. Good job, me.
..Br-broken..!
Even dazed, seeing it shredded gave relief—no more torture.
But that was way too naive.
"Nnght.. Jin..seong-ah..?"
Her hazy eyes shifted, landing on the 1:1 scale ass onahole "Lewd Sister's Big Ass" on the table. They widened, shoulders shaking.
Crunch.. Crunch..!
Not just shaking—my wilted dick surged back to life with blood flow.
..No fucking way! After all that cum!
Her stamina was unreal. I'd been average (by my standards), but fused with her? Endless erections, infinite semen. Mind-blowing.
"Haa.. I.. haa.. Jinseong.. Sis.."
She muttered, crawling to the doggy-style giant ass onahole.
Grab—!
Both hands seized the white, flesh-like ass cheeks.
"Jinseong's sister is..."
Schlup—..!
She pressed my throbbing glans against the plump pussy entrance—
"ME!!"
Slam—-!!!
—and rammed my shaft root-deep in one brutal thrust.
....!?!?
Stunned by the sudden assault—
"Can't forgive! Can't forgive! CAN'T FORGIVE!!!"
Slam—! Slam—! Slam—!! Slam—!!! Slam—!!
Her screams and the slapping impacts against the ass shook my entire "head."
...?!!
Too fast—the pistoning felt like my head dunked in water over and over. No scream possible amid the onslaught...
—Beeeeep—
...Tinnitus rang, and consciousness snapped.
———
Slap—! Slap—!
"Huuuhk.. Huhk..!"
Bam! Bam! Bam! Bam! Bam!
"Huuuhk..! Haaak..!"
On tiptoes, she slammed her crotch into the silicone ass lump.
"Oooht— oht—!"
Eyes rolled back, tongue lolling, hooting like a beast in heat—reason gone.
Slam—! Slam—! Slam—!
"Haaak—! Haak—! Even if my back breaks. Even if my muscles cramp from climax. Even with stinging pain from my new cock..."
"Heeeek—!!"
Bluuuurb—!!
All sensations dumped in one massive ejaculation.
"Heeek..!! Hiik..!"
Slap—! Slap—!! Slap—!!
Then back at it, slamming full body weight into the ass.
If coworkers saw her now, they'd never believe it was the same woman.
Slap—! Slap—-! Slap—!
Slam—! Slam—!
Kang Sion, the office lady, was beautiful, aloof, efficient—admired by bosses and subordinates alike, the perfect career woman.
"Ohhot...!! Ogook..!"
Two reasons for her fall: her mad obsession with her little brother...
'Jinseong-ah.. Jinseong-ah.. Jinseong-ah..'
Crunch..-!!
And the male urges from the cock now growing between her legs.
Bluuuurb—..!!
"Heeeek..!!"
Combined, they birthed this madwoman.
Slaaaam—! Slaaaam—!
'Jinseong is mine..! Everything of Jinseong's is MINE!!'
No matter how much she came or fucked her hypersensitive dick into pleasure holes, her endless desire never filled.
Even with her beloved brother as part of her body, mentally unsatisfied.
Bambambambambam—!
Bloooorp..!
She kept slamming hips, clenching balls, shooting cum.
Piiiing—-!
"Nghuk..!?"
But humans have limits. Sudden dizziness hit...
Schlop..!
She stumbled back, pulling out of the deep hole.
Schluuuk...
Her cock, coated in white cum-lube foam, was red and swollen from brutal friction.
"Haa.. Haa.. Haa.."
Sion glanced at her dick-brother, then the wrecked ass onahole spewing cum from its flattened hole.
Pffft..— Pffft..
"Pfft.. Pfuhaha!! Kyahahaha—!"
She cackled maniacally, staggering to her feet on wobbly legs.
"Mess with my Jinseong... my thing... and you get destroyed, huh?"
-Splatter—...!
She pissed bright yellow urine from her brother's cock onto the ruined onahole, grinning.
"Ngh..-"
-Thud..!
Then, like me, she passed out.
Shhhh...
The living room reeked of fishy semen, decorated with the siblings' spilled white fluid and torn, crushed onaholes.
