Sister's Outdoor Indulgence♡
Han River Park, packed with people. I walked right through the middle of it with my sister. Truth be told, I'd never been to a place like this before—it was my first time. At most, I'd only seen it on TV or the internet.
And yet here I am now, strolling with someone. A total babe, no less. It felt great. Even on my first visit, I walked tall and confident, thanks in part to the reactions from the crowd.
"Whoa, is that an actress?"
"She's insanely pretty. Fuck, she's hot as hell."
"That guy's so lucky, goddamn it."
"Fuck all you normies. Will I ever even get a girlfriend in this lifetime, let alone marry?"
I chuckled silently to myself. Marriage was just an extra in this world anyway. At the very least, I planned to get my fill of romance.
Sis pointed with her hand.
"Let's sit over there!"
"Sure."
We headed to a decent spot. I glanced at her subtly.
"You okay? Not uncomfortable?"
"Nope!"
"Still, at least sit on this." I took off my coat and spread it out for her.
Sis's eyes trembled for a moment before she flashed a quick smile.
"Ooh! My little bro's the best? Hehe."
"Haha."
We sat together and looked around. Countless people were wandering nearby or idly gazing at the Han River. The blazing sunlight made the whole scene feel strangely surreal.
That shop over there must've gone bust? Door's shut tight. I spotted one of those hole-in-the-wall convenience stores common near the river. Completely closed.
It would've been nice to grab something to eat or drink from the river for that authentic vibe. Then I turned to Sis.
Nah, she's got the vibe and romance all covered. Just her alone.
She brushed her hair back as the breeze blew, wearing a refreshing smile. I scratched my head watching her.
I asked casually, "Sis."
"Yeah?"
"I've realized I don't really know much about you."
"Oh? Come to think of it, I don't know much about you either, Si-hyeok."
Her eyes widened in a cute smile. She pondered deeply, then let out a sigh.
Even living under one roof, our hearts had been miles apart.
"Let's get to know each other while we spend time like this."
"Hehe, that's a great idea! My bro's so sharp—I love it! Gotta pamper you!"
"Whoa."
She grinned and patted my head. Her touch felt nice. Like a mom's hand. More precisely, like Mom's when she was younger.
Back then, I had nothing to fear. Same now. Just in a different way.
We silently gazed at the Han River together. Even just the two of us, it was plenty fun.
"Sis, do you have any circumstances you can't talk about or anything?"
"Hm? Nothing besides the stalker."
"Really? Like stuff you wanna do, or places you wanna go."
She tilted her head, narrowing her eyes at me.
"Why's my Si-hyeok acting like this?"
"You're always busy anyway. Even your hobbies, like cosplay."
"It's fun."
"Still, you should rest when you rest. I bet stress is piling up."
She looked at me in surprise, then smiled warmly. Like rich, aromatic coffee. Just like with Romi before, I was set on drawing out her true feelings.
And like spilling her guts, Sis opened up.
"Well, there is something."
"Yeah? What is it?"
"Can't tell you. Especially not you."
I let out a hollow laugh. She stuck her tongue out playfully at my reaction.
Some things just couldn't be helped.
"No means no, even if you cry."
"Ugh, are you ditching me?"
"There's something like that. Unless we suddenly go abroad somewhere."
"Tch."
I pretended to sulk on purpose. She kept glancing at me, aware of it, but just smiled weakly.
I advised her carefully. "Bottling up worries you can't share... they pile up. Turn into regrets."
"Huh?"
"After Dad divorced and I split from my real mom, that was my big regret. She was my whole world."
I showed my sincerity first. It was something I'd wanted to tell someone someday. I knew what Sis's issue was, but I wanted to hear it straight from her. At least get her to be honest with her feelings.
"But once I sorted my heart out, it got easier."
"You can really sort that out?"
More or less. If she couldn't sort it, better to spill. Even if not to me, it'd be good.
"I guess."
"If there's something you want, go for it boldly! You're the protagonist, Sis!"
I encouraged her with all my heart. Everyone's the protagonist of their own life. But someone as capable as Sis? She'd be the protagonist of protagonists.
She beamed broadly.
"Aw, Si-hyeok. Thanks."
"No biggie. Ahem, throat's dry. Want me to grab drinks?"
"Yeah! Carbonated water for me."
"Got it!"
I stood with a grin and stepped away. Headed to a nearby convenience store.
This should do it, right?
I went to the store, grabbed two affordable sparkling waters, and headed out. Lots of people around. Especially couples.
Good times. My good times too!
I smirked and returned to our spot. But Sis was gone.
Hm? Where'd she go?
No way she ditched me. No bathroom nearby either. Stalker maybe?
That'd be fucked. Damn, in this short time!
Dohoon watching from the shadows flashed in my mind. I frantically searched.
Looked around.
"Ha, fuck."
Sis was in eye-catching clothes. I searched urgently, ending up at that closed hole-in-the-wall shop from earlier.
Ah, shit. Where is she?
Fear crept in for no reason. Why did it remind me of separating from Mom?
Right then.
"Ngh, mmph♡"
A moan hit my ears. I crept to the back of the shop, wondering what it was. Shockingly, Sis was sitting there, legs spread wide.
Masturbating. Right here outdoors!

Insane?
It was a secluded spot, but jerking off?
I watched briefly, then moved. Hid behind a nearby tree.
Watched Sona.
This sis came all the way here and still... No way, because of my advice?!
I was flustered, but it thrilled me. Revealing her emotions so freely like that. It meant my words had hit home.
Straddling something, legs splayed wide. "Haa, hng, I want Si-hyeok's cock♥ Such a caring, huge cock♥" She licked her lips stickily, grinning lewdly. Then she jammed her middle and ring fingers into her pussy.
Started stroking up and down at first. Then, panting hard, she thrust in.
Not caring if her dress got dirty, she moved even more fiercely.
"Ngh! Ugh, hek♥ Haa, shove that cock in deeper, haa♥ Si-hyeok said that stuff. He's seducing me, that's it, ngh♥"
Seducing, huh? Kinda embarrassing. I barely stifled a laugh.
Sis was like an actress scripting her own scene. She shook her soft, curved waist while fingering her pussy.
"Ugh, ehng♥ Haa, stress, stress! But more than that, hikt♥ Craving that cock I can't have, it's frustrating, hng♥"
I was stunned by her mutterings. She liked me that much? Or rather, my monster dick?
Complicated.
Her fingers grew more passionate, like a succubus desperate for love.
Squelch squelch! Slurp slurp!
Her neatly split pussy hole clenched and pulsed. Clear juices trickled out, sparkling in the sunlight.
One eye half-lidded, she fingered harder. Breathed raggedly.
"Haa, haak♥ More, finger-fuck me deeper♥"
Head thrown back, twisted smile on her face. The gentle, caring Sis to everyone... now breaking down into a bitch in heat from pure lust.
Was this her true self?
Felt it from the drone footage, but damn, it's shocking up close.
Long white fingers plunging deeper. Her pussy hole red-hot. Female nectar gushing helplessly. Even matching the Han River's tide rhythm.
"Si-hyeok, pound me harder, knock me up♥ Please, fill me with your cum♥ Hng!"
Faster fingering. Her heaving tits started sweating. Jiggle jiggle♡ Boing boing♡
Staring at the sky during self-comfort, she glanced around. Missed me right behind diagonally.
Just kept repeating those filthy, slutty sounds.

"Driving me crazy♥ Haaang! If someone shows up, they might snap pics of me♥ No, I gotta get fucked by Si-hyeok first♥ Ngh♥"
Reason gone, spouting vulgar shit. Licked her lips again—glistening pink with saliva.
Pulled her dress top aside. Roughly kneaded her pure white milkers, upping the tempo.
"Agh, ahng♥ Hng! Hek, haa♥"
Her pussy squirted juices nonstop amid the nasty sounds. Relentless assault on it made her tremble.
Nipples rock-hard, poking the air. She added fingers one by one.
Squelch slurp! Pshht!
Wet sounds as her pussy gaped wide then clenched. She flashed a weird smile. Up close, tears streamed down.
Pain? Or...
"Hng, S-Si-hyeok♥ S-Sorry I'm such a cheap bitch♥ But I can't hold back, hng! Ever since I glimpsed your cock by chance, I keep thinking, haang♥ No other guy's does it for me♥"
Body slick with sweat, she ramped up her self-pleasure. Breaths roughening. Sticky fluids soaking the grass. Hips bucking like waves from bottom to top.
Her milkers swayed smoothly with the motions.
"So cum for me, your jizz♥ Si-hyeok's precious jizz♥ Hng, fill my lower mouth full♥ And my upper pussy too♥"
Squish squelch! Slurrrp! Splat splat! Slosh!
Fiercely finger-fucking. Worried she'd tear her hymen at this rate. She kept squirting juices intermittently but didn't stop—only went harder.
"Aang, hng, haang♥"
A bead of sweat on her chin. Rolled down, paused at her nipple. Then flung off by her intense movements onto the grass.
Legs spread as wide as possible, she was drenched in sweat.
"Ngh, oogh, hoguk♥"
Getting worse. Drooling now, fully exposing her defenseless bitch face.
"Hhek! S-Sorry, Si-hyeok sorry♥ Sorry, sorry, sorry for being this kind of girl♥ Haaang, finger me more, more♥"
Apologizing rapid-fire while fingering even faster. Thick juices reached her asshole, which clenched like it prayed for something to fill it.
Whole body a erogenous zone, she snapped her waist wildly. Milkers and firm ass quivering big time.
Boing♡ Taeng taeng♡
"Ugh, can't anymore♥ Si-hyeok please finish me♥ Cum deep inside♥"
At her limit, tits heaving off-beat like squats. Tears of ecstasy as she hit climax, head thrown back.
Splish splash♡
"Si-hyeok, I like you♥ No, haa! I love you, yes love you♥ Only you, love you, cum, ahng, I'm c-cummingggg♥"
Final moment, she orgasmed. Holding back moans with all her might. Waist arched like a bow.
Slurrrp! Slosh slosh! Splurt!
"Oogh, ooooh♡"
She collapsed limply onto the cold grass, twitching her hips now and then, just breathing.
Even then, her swollen red pussy leaked juices intermittently. Like it wasn't satisfied.
What now? Wait it out? Sigh.
Right as I thought that, she smiled like wrapping it up.
"Filled me up so good♥ Si-hyeok's cum♥ Hng. Gotta jump him tonight♥"
Yeah, this sis has it bad. For me, that is.
I quietly slipped back to our spot.
