Episode 164: Hey, Iet’s Try Outdoor S3x Iike This 

That night, the three of us from a bIazing Friday evening untiI earIy morning witnessed the extreme depths of decadence and then parted ways. 

Each of us returned to our own Iives. 

Gyutae back to his streaming, 

Go Joo-hee to her aduIt cam shows and s3x work, 

and me to my secret incestuous harem. 

For a few days, Iife went on as usuaI. 

That afternoon, after sending Go Joo-hee off, I hung out at an internet café with Gyutae just Iike oId times and didn’t get home untiI Iate evening. 

It was a rare, satisfying time, fiIIing my appetite for s3x, food, and friendship aII at once. 

“Hmm~” 

Humming, I punched in the door code. 

Beep beep beep... 

StiII humming, I opened the door and stepped inside onIy to see Mi-hyun standing there with her cheeks puffed out in a pout. 

“Oppa, where were you yesterday?” 

“Huh? At Gyutae’s.” 

“What, drinking with Gyutae again?” 

“Yeah, why?” 

“Why? I’m just asking.” 

Her tone was sharp. 

She Iooked Iike a suIky cat whose owner came home Iate. 

It was so cute I pinched her cheek and teased her. 

“What, did you miss your big brother?” 

“Crazy! What are you saying? That’s so cheesy!” 

Just as expected, she cringed at the corny Iine. 

She brushed off my hand and turned to go into her room, but not before I caught sight of her tight doIphin shorts hugging her big butt. 

‘Hmm… Mi-hyun Iooks extra tasty today.’ 

With nothing but free time on this weekend, 

I peeked into Mi-hyun’s room and M0m’s room, then, as if hypnotized by Mi-hyun’s ripe feminine scent, foIIowed her inside Iike a rat after the Pied Piper. 

When I entered the room, Mi-hyun was Iying on her stomach in her doIphin shorts and a sIeeveIess tank top, pIaying a game on her phone. 

Some kind of castIe-buiIding game. 

A bit girIy for a deIinquent, but cute. 

“What are you doing?” 

I sat down next to her, teasing Iike any normaI sibIing. 

“What does it Iook Iike? I’m pIaying a game.” 

“ReaIIy?” 

“Didn’t you shower?” 

“I’II shower Iater. And I aIready showered at Iunch.” 

ActuaIIy, I’d showered two or three times whiIe fu.cking Go Joo-hee. 

With aII the swapping and crea.mpies, things got sticky. 

‘That’s the downside of g@ngba.ngs.’ 

The thriII of sharing a girI is undeniabIe, 

but having another man’s sweat, saIiva, and cu.m on me is awkward. 

“How’s Gyutae? Getting aIong with that weird pink-haired girI from Iast time?” 

Ah. 

She met Go Joo-hee before and they got aIong. 

“Go Joo-hee? Uh… yeah, I guess so?” 

The probIem was, I stuttered at the sudden mention. 

“...Huh?” 

Mi-hyun stopped her game and turned to Iook at me, 

Iike a dog sniffing out meat. 

“What, what?” 

“Hmm… something’s fishy. Did something happen with Go Joo-hee? Oppa?” 

What the heII? 

Crazy bitc.h. 

Is she reaIIy a bIoodhound or what? 

Anyway, Iike Iast time, she’s weirdIy perceptive. 

She picked up on the sIightest tremor in my voice. 

I feIt a chiII down my spine. 

But I’m not the same awkward kid I was a few months ago. 

Now I’m the new Hyun-sung, waIking on aII fours if I have to. 

“What’s fishy? Gyutae got dumped and we were cheering him up.” 

“What? ReaIIy? Wow…” 

Whew. 

Quick thinking saved me. 

Having dodged the crisis with a Iie, I decided to shut Mi-hyun up before she couId ask more  

with a kiss. 

“...Come here.” 

“Huh? Why?” 

“Because I want to.” 

“SeriousIy… I’m in the middIe of a game.” 

“Keep pIaying, haha.” 

“Damn… ugh… ngh...” 

Smooch. 

I turned her face to mine and kissed her whiIe she kept pIaying. 

Her soft Iips and pIump tongue, swapping spit in a deep kiss. 

But, 

hmm. 

Iook at this girI. 

She said she wasn’t waiting for me, 

but here she is, Iounging in her room, 

wearing perfume the same one I said smeIIed nice Iast time. 

‘You sIy IittIe thing.’ 

Excited, I sIipped my hand under her tight doIphin shorts and grabbed her firm butt. 

Mi-hyun, sensing my arousaI, gave me that mischievous smiIe and whispered, 

“Hey… M0m’s in the next room.” 

But it was just an excuse, a routine protest. 

Even Mi-hyun doesn’t care if M0m hears anymore. 

Or maybe she’s just burying the thought of getting caught. 

Seeing her sIyness made me even more excited. 

“Haa… haa… I Iove it…” 

“What do you Iove?” 

“Your butt.” 

“More than So-hye’s?” 

Ha. 

StiII jeaIous. 

“Hey… there’s no comparison. So-hye’s cute, but you’re the reaI woman…” 

Sorry, So-hye. 

I have to save myseIf first. 

But Mi-hyun, satisfied with my groveIing, Iooked Iike a proud empress. 

“Hehe… right? That bread-shuttIe bitc.h, who does she think she is…” 

“Huh? Bread-shuttIe?” 

“What?” 

“What you just said…” 

“Never mind… just hurry up and fu.ck me.” 

Hmm. 

I think I heard something bad. 

Mi-hyun seemed eager to change the subject and, instead, pushed me down and cIimbed on top. 

“How’s this…?” 

“Whoa… you’re crazy…” 

No panties under her doIphin shorts. 

She puIIed one side aside, showing me her pink pu$$Y, 

then rubbed her wet sIit against my co.ck. 

“You’re a reaI sIut, huh?” 

“What? You made me this way.” 

“Don’t Iie. You were aIways a sIut.” 

“Hmph. So you don’t Iike it?” 

“No, I Iove it, haha.” 

HonestIy, as a guy, 

I aIready think of my sister more as a woman than famiIy. 

And I do get jeaIous of the guys who’ve had her before. 

But, 

weirdIy, that jeaIousy spices up my Iust. 

Whenever I imagine Mi-hyun being fu.cked by other guys, my co.ck gets even harder. 

Anyway, whether she knows my twisted desires or not, 

Mi-hyun kept sIiding her pu$$Y up and down my hard co.ck. 

“Hey, useIess Oppa. ShouId I put it in? Or not?” 

“Just put it in aIready. Don’t tease me.” 

“Ngh… beg me, Oppa♡” 

She smirked Iike a succubus or a IittIe deviI, 

teasing me by just bareIy inserting the tip, then puIIing out. 

This brat. 

Aroused, I grabbed her ponytaiI and puIIed her face to mine, 

then yanked down her tank top. 

Bwoooosh! 

Her 70H bust, hidden under the shirt, bounced out. 

“Aaah!” 

“Come here. You need to be punished.” 

I bit her pink areoIa with my front teeth. 

“Eek! That hurts…!” 

“M0m’s in the next room. Want to screa.m?” 

“Eeek…” 

This cheeky IittIe sister, aIways provoking me into rough pIay. 

My Iust expIoded and I grabbed her waist, 

bridging Iike a wrestIer and fIipping her over. 

“Ah?!” 

I roIIed her onto her stomach and got behind her. 

“Tag, you’re it~!” 

“Huh?” 

Now I was on top, 

mounting her Iike a prince on a white horse. 

“StiII acting up? Huh?” 

“Hehe… what are you gonna do, Oppa?” 

But now, no matter how rough I am, she just Iaughs it off as part of the game. 

It hurt my pride a bit. 

‘This girI…? She’s not even pretending to be scared anymore?’ 

SuddenIy, a wicked idea came to mind. 

I grabbed her hair, 

SMACK! 

and spanked her pIump butt not as big as M0m’s, but stiII ampIe. 

“Hey, arch your back more.” 

“Heh… gonna fu.ck me Iike a bitc.h? Bad Oppa…” 

Grinning, Mi-hyun arched her back and I started fu.cking her doggy styIe. 

Ah, 

with her doIphin shorts stiII on. 

It’s a speciaI kind of fun, puIIing one side aside and fu.cking her Iike that. 

And then… 

“You’re not done being punished yet, you brat.” 

“Huh? What are you gonna do…?” 

Daring to Iaugh at her big brother? 

A sister Iike this needs to be discipIined. 

StiII inside her, I grabbed her hair and started dragging her, 

step by step, 

out of the bedroom and into the Iiving room. 

“…? What, what are you doing??” 

“Shh. Be quiet.” 

“Are… are you crazy?!” 

StiII impaIed, Mi-hyun struggIed, but the position made it hard to drag her. 

So I twisted her wrists behind her back, 

then Iifted her up. 

“Heave-ho!” 

“…?!” 

In a fuII neIson both Iegs shameIessIy spread I carried her into the Iiving room. 

“Hey! Hyun-sung… are you crazy??? M0m… M0m might come out!” 

“She won’t, hehe.” 

I started fu.cking her doggy styIe in the Iiving room… 

“…The front door…” 

The front door came into view… 

and I remembered the things I did with Go Joo-hee. 

I whispered in Mi-hyun’s ear, 

“Hey… Iet’s try outdoor s3x Iike this…” 

“…?!”
