Onahole Sister's Casual Use
“Goodbye!”
“..G-goodbye..”
Eun-ae's cheerful farewell was a far cry from her brother's dying croak of a response, but I let it slide. Jerking off usually takes a decent chunk of stamina, after all.
I got home. No sign of Joo-young sprawled on the couch like old times when I opened the front door. Mom wasn't in the kitchen either. But with everyone's shoes there except Ji-na's—who was off at her lectures—they were probably just chilling in their rooms. Though seriously, was this bitch Joo-young just lounging around every damn day?
Knock knock.
“Noona, I'm coming in?”
It was still broad daylight, so she probably wasn't asleep. No answer from Joo-young, but I opened the door and stepped inside anyway.
“..”
The room looked the same as before. The only difference was a fresh batch of crumpled tissues scattered around, replacing the ones I'd tossed last time.
Joo-young sat in front of her computer in the same old running shirt and panties, just like always.
“Oh? You're back?”
“Watching streams again?”
“Nah.. well.. I mean, it's only been a few days since I quit my job..?”
Her tone made it sound like she was justifying her all-day gaming marathons, which was kinda ridiculous. I wasn't even planning to call her out on it.
I slipped behind her chair and grabbed her tits with both hands.
“Heh heh, what the hell. Is that it? You had me worried for a sec~.”
She'd tensed up thinking I was here to scold her, but relaxed once she realized I just wanted to grope and fuck. Simple as that.
I kneaded her tits while peering at the monitor.
“Who's this?”
Some streamer I'd never seen. The chat was flying by, so she wasn't a noob.
“You don't know her? Wow, total munjini.”
“Says the shut-in.”
“What the fuck, punk? Wanna die?”
“...”
I pinched her nipple lightly.
“Ow! Hey! I told you to handle a girl's nips gently!”
“Noona pissed me off.”
“Fuck.. can't even fight back 'cause I'm just your onahole...”
True that.
“You're my onahole, right, Noona?”
“You little shit.. you told me to say it, and now you forget..?!”
“Haven't needed your pussy lately.”
“You raped it.”
“....”
Couldn't argue with that. I quietly kept massaging her tits. The fabric dulled the feel a bit, so I slipped my hand into her cleavage for the real thing.
Joo-young didn't react at all to the groping—just kept watching her stream. Expressionless and unresponsive was the best.
-Ah, what the hell~! No way! Is this even a game?!
The speaker blared the female streamer's voice. She was playing some mobile gacha game. That was her rant after getting wrecked in PVP by a whale at her score bracket.
“Hee hee, don't spend and you lose, dumb bitch..”
“...You don't even have money to spend.”
“Fuck off. Keep saying shit that pisses me off? Who the hell are you to lecture your noona on life advice?! Hah! I've lived longer than you, punk!”
“Sure thing, ajumma.”
“You fuck..!”
She spun her chair around, grabbed my cheeks, and stretched them out.
“You little shit.. grown a lot, huh? Talking back now..?”
After yanking for a good while, she let go and turned back to her stream.
“...We fuck and everything, so talking back's no big deal..”
“Nope~. No can do~. Groping, fucking, rape—fine, whatever. But talking back? Unforgivable, little bro.”
“...”
Fine, whatever. Back to the tits.
-Haa.. screw it, guys.. wallet... unsealed..!
The streamer started rolling gacha. I watched her blow 300,000 won while kneading my blood sister's tits.
“...Wanna put it in.”
“Hm? Oh, go ahead. Do whatever.”
She casually shucked off her panties and tossed them somewhere. One more piece of clutter in the room.
Joo-young stood, gripped the desk with both hands, and thrust her ass back at me. Her firm cheeks greeted me, along with her now hairless asshole and pussy—totally different from before.
“Shaved?”
“Yeah. It's gross otherwise.”
“For me?”
“Dumbass. You think? I did it 'cause it looked nasty when I masturbate.”
...Cheeky bitch. To punish her, I lined up my dick with her pussy and slammed in balls-deep.
Squelch.
“Tsk tsk, how much did she blow? Such a waste of cash.”
Even with her little brother's cock buried inside, she just chilled and commented on the stream.
“She earns that much.”
“Goddamn it. Didn't I say no smartass remarks?”
Urk. She scolded me while clenching down on my dick.
“Hee, feels good?”
“...Yeah.”
“Be good to your noona~. What other sister lets her bro use her pussy?”
“..It's me, so of course.”
“No..! That's not what I..! Fuck it. Just cum already.”
Her pussy squeezed hard again.
Squish.
I couldn't hold back and flooded her womb with a massive load.
“Always so quick, but the volume's insane. Pregnancy-specialized dick? You're dead set on knocking up your noona, huh.”
“Hoo..!”
I started thrusting again to savor her pussy.
-Kyaaak! Why does this bitch keep showing up!!
“Hee, she's perfect for you, you slut.”
Whether her little bro was using her pussy or not, Joo-young just chuckled at the stream to herself. Sure, he was her blood brother, but it was Min-jun, so... whatever. Mom did it with him, and that bitch Ji-na too. No big deal. She didn't care if her bro fucked her pussy.
Squish.
She'd just clench occasionally. And every time, I'd cum.
“Hee hee, total jo-roo.”
She kept teasing, but it didn't faze me. Thrusting into her offered-up ass and pussy while she talked shit? Adorable.
Smack.
I gave her ass a light slap.
“Hey! Why hit my ass?”
“You clenched.”
“..Haa.. I'll clench for you, so don't hit. It hurts.”
“Got it. Sorry, Noona.”
I rubbed the spot gently. Pleased, she tensed her lower body and kept squeezing my cock.
Squish.
Her tight pussy milked me into another creampie.
While pounding away forever, the stream-focused Joo-young suddenly spoke up.
“Hey, I'm tired. Let's do it sitting.”
I sat in her chair. She impaled herself on me reverse cowgirl-style and kept watching the stream. I buried my face in her neck, inhaling her scent as I enjoyed her pussy. She stroked my head and clenched rhythmically.
Blissful pussy time. Her depths filled with my cum, chair and floor turning into a cum-soaked mess. Finally, I pulled out.
“Huh? Done already?”
“Yeah..”
She knew her womb and pussy were packed with her little bro's seed—enough to knock her up—but stayed chill.
“Whoa.. look at all that cum.. your stamina's no joke..”
She gawked at the overflow and the mess on the floor. My hands still roamed her tits, face nuzzled in her neck, but Joo-young couldn't have been more relaxed.
“Hey.... clean this up.”
She ignored the groping and sniffing—didn't mind her perv bro—but hated cleaning cum.
“You clean it, Noona.”
Me clean my own cum? Fuck no.
“Ugh, you shot it. And does an onahole clean itself? No, the owner who used it does. So who's your onahole's owner? You! So you clean!”
“...”
Logically sound, kinda.
“You clean it, Noona.”
“Fucking punk.”
Still no. She grabbed tissues and started wiping. I jerked off with her freshly discarded panties, watching.
Her pussy kept leaking my cum while she mopped the floor.
“One's busting ass cleaning, and the other's casually beating it to his blood sis..”
She grumbled.
“You never clean normally, so might as well now.”
“Bullshit. You're just lazy.”
“Yup.”
“Fuck.”
Splurt.
I hit my limit and shot ropes onto her body.
“Fuck! Why on me?”
“Bukkake, duh?”
“I know.. but.. haa..”
Cum splattered her thigh and PJs. I started stroking again.
“Hey.. not cumming again, right..?”
She eyed my dick nervously.
Splurt.
This load sprinkled her hair.
“.....You dog.”
“Hey now. Cursing at me?”
“..! N-no.. fuck, that's not..!”
I got serious, and she panicked like a criminal caught red-handed.
“Heh heh.”
Even with her bro's cum all over her and mad at her, she couldn't rebel. Her flustered cuteness made me chuckle.
Realizing it was a prank, she puffed her cheeks like Ji-na, signaling I'm sulking~.
“Don't prank like that, fucker..”
Pretty spooked, still muttering curses even after catching on.
Splurt.
My hand hadn't stopped through it all. The fresh load hit her face.
“...Ugh.. smells like cum, fuck..”
She scrunched up, face glazed.
“Hoo.. think that's enough.”
“Please, yeah. Even horny beasts wouldn't go this hard.”
Like her fear was fake, she snapped back.
That's my noona.
“Hated it?”
“..No, fuck, don't say it like that—you make me speechless... I'd die if I said yes..”
“Wasn't gonna bitch. Just curious. Did you hate it?”
How'd she really feel about her bro using her pussy and bukkake-ing her?
“...Pussy use was fine.. but the bukkake was a bit..”
“..Got it. More next time.”
“Fucking asshole. Knew you'd say that.”
“Obviously.”
“Total dick.”
Grumbling to herself, she resumed mopping cum.
“Work hard.”
Smack.
“Ah! Fuck, hurts, you dog!”
“Sending you 10 mil today~.”
“Love you, Min-jun~! Come use me anytime!”
“....”
“What, fuck. Get out already.”
I took one last look at her still-leaking pussy, shut the door, and headed to the living room.
