"Fucking look at this prick, ignoring his queen-tier sister's texts?"
Ji-min storms into her Sekyung Villa apartment, huffing like a pissed-off milf, and flops her *huge*, jiggly tits onto the couch.
Ghosting her calls, acting like I'm not holed up in Reboot? My go-to fuckboy move. Ji-min's dealt with my shit forever, but I've gone full bastard. Used to grovel for her cash before blowing it on gacha, at least pretending I gave a fuck. Now? I'm straight-up milking her wallet for *Legacy of Heroes* pulls like a shameless cock-jerker.
"If I was there, I'd be strangling his neck with my thick-ass thighs, squeezing till his cock begs!"
I'm too beefy for her old-schoolyard bullying, but… 'Shit was sweet back then.'
When we were tight, Ji-min could smack me down for being a dick. Now, out in the corporate grind, she's stuck stewing, and it's eating her up.
---
Ji-min's got a soft spot for her fuck-up brother. Friends always shat on her for dragging me along, but she never trashed me.
"Haa… Worried about Jang-seok's dumb ass."
Grown man jerking to mobile games? Dumping insane cash? Ji-min, adulting hard, can't get it. This month, she slid me 5.2 million won—enough to live like a king for months. Me? Torched it in a week on gacha. No wonder she's fuming.
Back then, I'd kiss her ass for cash, but now…
"Ugh, as his sister, I'll eat the L."
Thinking about sucking my cock last time, Ji-min licks her lips, hungry. Gotta forgive her favorite cock-hound brother.
Stripping for a shower, she gropes her massive, sweaty tits, pussy tingling. Why? My nasty-ass video.
*[Beatrice-chan, I'm unloading! Fuuuuck]*
"That fucking moron…"
Dropping stacks on digital waifus and sending his sister jerk-off vids? My bullshit's beyond her.
*But…*
"If it got him *that* hard…"
Ji-min's hands slide, kneading her fat jugs, pussy dripping as she relives fucking me. Her nipples pop *hard*, body screaming she's still cock-drunk. She's jerking herself raw in seconds.
"Haaa… Sister wanking to her brother's dick vid? Fucking filthy."
Word is, the stronger the brother's cock, the harder sisters crave it. That's why sisters get shit—using family ties to slobber on their brother's dick.
'I *asked* to suck, so I'm not *that* slutty.'
Ji-min smirks, squeezing her tits, tongue lolling, eyes glazed, lost in sleazy self-fucking.
"Hngh, hooo…"
A quick cum hits, but she's greedy, fingering her soaked pussy, twisting her nipples for more.
Then—
*[Here's Beatrice-chan you paid for, sis!]*
"Haaa… Throwing cash at fucking mobile games…"
She groans at my idiocy. My cock's a beast, but she hates me wasting my load on this. Wants me chasing a real future, like some Harin-level mom nagging.
---
Call and bitch me out? Ji-min curls up, rubbing her clit raw.
"Haaa… Hoooh…"
Phone loops my cock-stroking vid. She's glued to my throbbing dick, wishing it was pounding her pussy, not her fingers.
"Fuck me again… Jang-seok… Slam my pussy… Breed your sister's hole…"
She moans dirty, pinching her clit. My cock's alpha stench seems to pulse through the screen. Her cheeks burn, nipples so hard they twitch at her shirt's graze.
Didn't know her pussy could get *this* slutty.
'Cock changed everything.'
Thought she wasn't some dick-starved chick. But my cock's raw, brutal visuals? Rewired her brain. Life's different now.
Just eyeballing my dick feels like pussy-victory—dopamine flooding her brains out. In this world, cock rules. Pussy-havers are its bitches.
"Haaa… Hngh… Pussy… Fuck my pussy… Spoil me…"
Instead of Beatrice-chan, Ji-min craves my cum bloating her womb, ramming fingers deep, twisting her rock-hard nipples.
Writhing on the couch, lonely, cock-hungry.
Today, she can't nag. Wanking to my vid instead of lecturing? Fucking embarrassing.
Part of her's humiliated…
But another part wants to ditch her office-lady mask, go full slut, let her pussy run the show.
"Haaa… Haaa… Haaa… Jang-seok… My pussy's cumming… Cumming… You'll fuck me, right?"
*[Fuuuuck! Blasting Beatrice-chan's face!]*
"…Hngh… Heh…"
Ji-min giggles mid-climax, thrown off.
"Haaa, hahhh…"
*Twitch. Twitch.*
She arches, clutching her sweaty, massive tits, pussy exploding. The cum drags on.
*Twitch, twitch…*
"Haaa, haaa… So fucking good…"
Guilt slams—she got off to my cock. But…
'Jang-seok's fault for sending that sleazy shit…'
No respect for his dick. Flashing it like that? No chick's resisting, not even his sister.
She strokes her tits, excusing herself.
"Hooo…"
Nag vibe's dead.
She checks my game—*Legacy of Heroes*.
AKA *Legacy of Heroes*. Pull hot, unique heroes, raise 'em, raid or defend territories. Infamous for wallet-raping gacha. Collecting heroes burns cash, but this game's evil. Rare heroes need dupes for "Legacy Tokens" to roll premium pulls, with dogshit odds. Completionist hell—banned in some places. Beatrice's pull cost? 18 million won.
"Fuck… That much?!"
Ji-min's shook but, curious why I'm hooked, tries it.
[Welcome, "InvincibleSis"!]
[Free 100-pull for your first hero. Go?]
"Hmm… Free? Sure."
[SSR Hero Venom Acquired!]
[SSR Hero Ren Acquired!]
[SSR Hero…]
100 pulls spit 13 SSRs at 0.6% odds. Rainbow screen flashes. Ji-min shrugs.
'Feels lucky. Nah, just me?'
Using "Legacy Tokens," she hits a 10-pull.
[SSR Legacy Hero Beatrice Acquired!]
[SSR Legacy Hero Silverfang Acquired!]
"Yo! These are rare, right? Hell of a start."
She doesn't know it, but Ji-min's gacha luck is fucking godlike. I'm decent, but she's a legend.
No rerolls—she builds a cracked account, auto-wiping early stages, smashing skill grinds, getting comfy fast.
"Hmm. Kinda hot… I'm lucky as fuck."
Friend requests pile up. Whale account vibes?
Friends borrow Legacy heroes for quests. Beatrice and Silverfang are meta gods, making Ji-min's newbie account a star.
"Now I get why he wants stacks."
She's feeling my gacha lust.
[SSR Legacy Hero Beatrice Acquired! Breakthrough!]
[SSR Legacy Hero Silverfang Acquired! Breakthrough!]
"…Huh? Just play, and it drops. Why pay?"
Can't grasp spending on free shit.
Memory hits—
"Sis! Pull for me!"
"What? Mobile games? Cash sink."
"Please! You're lucky. Just tap the 10-pull. Give me your magic!"
"Ugh… Done. Don't cry if it's garbage."
"Holy fuck!! Four SSRs?! You're a goddess, sis!"
"What?! Watch your mouth, Jang-seok! Get here!"
"Thanks, sis!!"
"So stoked…"
'Maybe I kicked off his gacha bullshit…'
If her luck had tanked, maybe I'd be normal. She remembers my dopamine-drunk face melting at her pulls—bad move.
'He was cute then. Now he's a stud, hard to nag.'
Remembers me sweet-talking for snacks, swearing to repay her big. Still a kid, but she trusts I'll grow up.
'Who's worrying who?'
Sister stressing over her cock-prime brother? Hotshots like Harin probably cream to lock me down. My dick's a lifetime meal ticket.
But why's she so hung up? It's like habit—unbreakable love.
Others see me as set, but Ji-min's not buying it.
'Mobile games! Fucking evil!'
Single-purchase games? Cool. But brain-frying, cash-torching gacha? Gotta end it.
Idea sparks…
'What if I crush him at his own game?'
*Legacy of Heroes* lets strong players fuck up weaker ones. Guilds are hardcore—raid seasons mean skipped meals, voice chat 24/7.
How a shut-in like me plays this hardcore? No clue. But Ji-min knows one thing:
'Keep losing, you ragequit.'
Games burn you with bullshit RNG. What if *she* fucks my game?
"Fuck yeah…"
Join my game, wreck my ass. That's sisterly love!
Ji-min dives into grinding…
[SSR Legacy Hero Beatrice Acquired! Breakthrough!]
[SSR Legacy Hero Silverfang Acquired! Breakthrough!]
'Why the fuck spend cash?'
Her golden hands go ham.
