135. AV Little Sister Peeping on Big Sis's Fuckfest "This is Fucking Insane!!!"
'I'm losing my fucking mind!!!'
Ha-jeong had returned to her room midway through eavesdropping because Mom interrupted, but the sounds she'd heard earlier left her head spinning.
'N-No way... They were really doing that in her room!?')
A man casually tossing out words close to insults and abuse—like "anal masturbation" and calling her sister a female pig. And her sister, hearing it all, kept letting out those lewd moans like she didn't hate it one bit.
'No way in hell!!')
For Ha-jeong, who despised men, that kind of talk and treatment was utter bullshit. And yet, the idea that they were doing it in a house full of family, using studying as an excuse? Unbelievable.
'I must've misheard... Yeah, that's gotta be it.')
She hadn't seen it with her own eyes—just heard through the door, so parts were muffled. When she'd cracked it open, they looked normal, just studying. Nothing certain.
'He said he'd come tomorrow too, so then I'll check for real...')
If he was just toying with her sister, Ha-jeong would stop it as the little sister. Hasun might be a bit unreliable, but she was still precious family. If that guy was defiling and playing with her like that, it was up to Ha-jeong to block him.
"B-But no way... A-anal? There's no feeling there, right? Th-That's ridiculous!"
She only knew the basics of sex, so the idea of feeling pleasure from anal was beyond her.
"M-Maybe right now?"
The walls between rooms weren't thick, so she pressed her ear against it, but no sounds came. It almost felt like those earlier noises were a hallucination.
"I know it's bullshit, but... J-Just in case..."
The phrase "anal masturbation" stuck in her head like glue. Face burning red, Ha-jeong slipped under the covers and quietly pulled off her panties.
'This is just to check... Definitely not doing anything weird!')
Convinced her sister couldn't be some anal-loving pervert, Ha-jeong figured she'd test it on herself. If she didn't feel anything, neither would Hasun. Flimsy logic, sure.
Cautiously, she reached back toward her ass.
Squelch.
"Nngh♥"
Her finger brushed her anus, and an involuntary moan slipped out, but she played it cool and kept rubbing.
Squelch squelch squelch squelch.
"Th-This... Nngh♥... Doesn't feel like anything♥"
Her body was heating up a bit, and she had to bite back moans if she got careless, but she figured it wasn't real pleasure.
'Must've been a dildo or something in her ass... Ngh♥')
She was shocked inside at the thought of something thicker than her finger stuffing her sister's butt.
"Sis must be getting forced into it♥ Nngh♥ Haaang♥"
The family had no clue how perverted Hasun might be deep down, so Ha-jeong imagined she was being blackmailed or threatened by the guy.
"Blackmail and dirty stuff♥... Ah♥"
That man started popping into her head. His lecherous gaze raking over her.
Squeeze.
"Mmph♥♥"
Grabbing her huge tits sent moans leaking out, her finger starting to probe deeper into her anus.
Squelch squelch squelch squelch.
In her fantasy, the man was forcibly groping her breasts and fucking her ass.
"Filthy♥... Hnng♥... Bastard♥..."
She hated men, but imagining him doing it to her made her body burn hotter.
"Not just Sis♥... Nngh♥... Me too♥ Hnng♥"
The shameless prick reaching for her, the little sister (in her delusion).
Squelch squelch squelch squelch... Plunge!
"Mmmph♥♥"
Twitch twitch twitch.
Shoving her finger as deep as it would go, she convulsed into orgasm, the aftershocks lingering for minutes.
"S-See? Felt like total shit!"
Remembering what she'd just done, her face flushed crimson as she denied how good it felt. She headed to the bathroom to wash up, thinking:
'If he's really doing weird shit to Sis... I won't forgive him!')
She had no idea the fantasy she'd just had would soon become reality...
............................
The next day arrived—the day that guy, her sister's "study friend," would come over again. Mom was out at a meeting, so just Hasun, the guy, and her at home.
"Hoo... Let's go in."
Knowing they'd probably be there already, Ha-jeong slipped quietly into the house.
- Ah♥ Aaang♥ Ah♥ Nngh♥
'M-Moans!!'
The moans she'd doubted yesterday hit her the second she entered. She hadn't seen it yet, but curiosity burned—what the hell were they doing to make those sounds?
Gulp.
Creeping silently to her sister's door, she found it slightly ajar. Yesterday was just sounds, no proof—but now, she could peek right in.
Peering through the gap with bated breath, an unbelievable sight unfolded.
Squelch squelch squelch squelch.
"Ooh♥ Ooh♥ Ooh♥ Ooh♥ My shithole f-feels so good, Master♥ Ooh♥"
"Shake your hips more sluttily."
"Yesss♥♥"
Ha-jeong froze on the spot at the sight proving she hadn't misheard yesterday. Naked, legs spread wide in a squat, Hasun displayed her massive ass. A huge dildo was buried in her asshole.
'S-Sis...')
Squelch squelch squelch squelch.
"Bwooooh♥♥"
Shaking her ass up and down with vulgar cries, Hasun masturbated her anus with the dildo right in front of the guy. Not the timid, kind sister Ha-jeong knew—just a shameless bitch in heat.
'H-He really did that to Sis...')
The second the parents were gone, ditching studying for depravity. And such an extreme perversion? A massive shock to Ha-jeong.
"How's masturbating after a full day banned?"
"Feels amazing♥♥ I keep cumming from my shithole♥♥"
'Why is Sis obeying that guy... L-Like that... Haa♥... Haa♥...')
"Disobey again, and I'll leak that video from last time. Be ready."
"Eek♥ P-Please not that♥ Ooooh♥♥"
"Cumming before you even finish talking? What a hopeless sow."
"Sorry, Master♥ Ooh♥ Ooh♥"
'Knew it! He has some dirt on her!!')
Convinced her sister wouldn't debase herself like this willingly, Ha-jeong figured blackmail forced her hand.
'E-Even so, that stuff♥... Haa♥...')
"Shake it more sluttily."
"Yesss♥ Hiiih♥♥"
Hasun's jiggling ass went wild—up, down, side to side—in even trashier motions to please him.
'S-Sis♥...')
Squelch.
"Mm♥"
Seeing it, her hand unconsciously drifted to her pussy.
Squelch squelch squelch squelch.
'I'll save you♥ Ah♥ I'll help you♥')
Barging in now wouldn't help with that leverage over Hasun.
Slap!
"Bhuuuuh♥"
"Knew it—nothing makes you squeal like a spanking."
'Th-That trashy bastard♥♥')
Squelch squelch squelch squelch.
Horrified as he casually smacked her sister's huge tits with a grin, but Ha-jeong's fingers sped up, pussy juice dripping to the floor.
"Your favorite cock."
"C-Cock♥ Cock-sama♥♥"
'Th-That's a cock!?♥')
He dropped his pants, revealing a dick way bigger and thicker than the dildo—one even Ha-jeong, who occasionally watched porn, had never seen.
Gulp...♥
Ha-jeong held her breath, heart pounding like mad as she watched what he'd do with it to her sister.
"Open your mouth-pussy."
"Yesh, Mashter♥"
Mouth agape, tongue out, Hasun wagged it sluttily, begging for cock.
'H-How did he turn Sis into that♥ Ah♥... Haa♥')
Not the sister she knew—a total bitch in heat, drooling at the sight, thrilled by her own sluttiness. It almost seemed like she wanted this.
'No way Sis wants it♥ Definitely that guy♥ Nngh♥')
Squelch squelch squelch squelch.
"Suck."
"Thank you, Master♥ Hnng♥ Shluuuurp♥♥"
Permission granted, Hasun engulfed the cock and slurped greedily.
"Slurp!♥ Glurk!♥ Hngh!♥ Shlooop!♥"
Cheeks hollowing, drool dripping, she devoured it like a feast.
Gulp...♥
'H-How fucking tasty can it be♥')
The room reeked of cock and bitch. Beyond her sister's scent, that male musk hit Ha-jeong hard—stirring her nostrils as she inhaled deeply without thinking. Purpose forgotten, she masturbated furiously, peeping on their fuck.
"Close call. Gonna creampie that shithole proper—get on the bed and spread."
"Y-Yes, thank you♥"
On all fours at his command, Hasun gripped her cheeks, spreading her shameful hole wide, winking it lewdly.
"Haa♥ Haa♥ Haa♥ Haa♥"
Anal mating—not pussy—and still Ha-jeong couldn't look away.
Squelch.
"Boooooh♥♥♥"
Plunge!
"Ooooooooh!!?♥♥"
The massive cock buried balls-deep in her sister's ass. Hasun's beastly howls of ecstasy made Ha-jeong's pussy clench on its own.
