Sister Who Wants to Submit to Her Little Brother (1)

Squiiiish—!

“Hnnnghaaah♥”

Thwack! Thwack! Squelch, squiiiish!

“Haa, haa... Siwoo... Siwoooo...”

Elena, sprawled on the sofa, clung to my neck, hanging off me desperately. Her sweat-soaked blonde hair swayed, tickling my face. I growled low in time with my thrusts.

“Has that village head ever fucked you like this?”

“No... never! He doesn't know anything about this!”

“Not even in Russia have you ever felt this good?”

“No... never once... my brain's melting...♥”

Elena shook her head, letting out a lewd cry. The living room AC blasted cold air nonstop, but the room burned even hotter. I lifted one of her arms with a hand. Her smooth, sweat-slicked armpit gleamed wetly, exposed. I pressed my nose to it and blew a light puff of breath.

“Ha, haaht... Siwoo, there... that's embarrassing... hnnnghaaah♥”

Elena's eyes glazed over in pleasure as she gazed down at me, her body twitching. She didn't even know what sex was—just that it felt amazing. But her armpit was a little embarrassing. Her face flushed as she murmured softly.

“Elena's armpit... if it smells, Siwoo disappointed. Hnnght—!”

Before she could finish, I stuck out my tongue and licked a long, slow line from the bottom center of her armpit upward.

“Nah. It's fine between friends.”

“I-is that so? Sex ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠friends can lick armpits too♥”

After that, I obsessively licked and nibbled her armpit while relentlessly pounding her from below. Squelch— squiiiish— slap! The cheap leather sofa slapped against her wet ass, echoing vulgarly through the living room. Once one armpit glistened with saliva, I had her lift the other. She gripped my hair tight.

“Hnnnght...♥ Siwoo's a pervert friend...♥”

After a good long while of thrusting into her pussy and sucking her armpits, I'd had my fill of her armpits and tits. I pulled back up.

“Get on your stomach.”

I flipped her over. Elena's pale ass stuck up in the air. Her pussy hole, freshly fucked and gaping inside out, and her deep pink asshole were on full display. I slammed my cock deep inside from behind again, leaning forward. My hard upper body pressed tight against her smooth back. I pinned her torso down and roughly kneaded her massive tits with both hands. Elena drooled like a bitch in heat under me.

“Hnnnght—♥ Haaaangh♥ Siwoo's hands feel so good♥”

I nipped her earlobe lightly and whispered—no, commanded.

“Listen up, Elena. From now on, don't even hold hands with your husband. Got it?”

“Yes... yes! I won't! His hands are dirty! I hate them!”

I glanced at the app screen, out of her line of sight, and checked the Adultery Addiction tab. [Lewdness] and [Target Recognition Contrast]—the sub-options under the latter, [Spouse Disgust ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Sensitivity] and [Admin Superiority Imprint], had skyrocketed on their own without me touching them. Now, just seeing her husband the village head would trigger visceral disgust in Elena. Maybe even outright loathing.

I'd wrecked one marriage in a matter of minutes, but no guilt or negativity stirred in me. It wasn't even a real family—they didn't love each other. Just a marriage of duty and obligation. I'd freed her from that misery; if anything, I deserved thanks.

Feeling my cock start to throb, I straightened up again. I gripped Elena's ass tight. No holding back the building orgasm—I ramped up speed and unloaded right there.

Spluuuurt— bluuuurb! Bloooort! Bluuuup— splat— splat—!

“Haaaaaaaangh—♥”

The hot rush filling her womb pushed Elena over the edge. Her pussy walls twisted and clenched around my cock like a vice. Eyes rolling back, her whole body convulsed as she buried her face in the sofa. I pulled out and sat beside her collapsed form. As she panted exhaustedly, I gently brushed her sweat-matted bangs into place.

“How was it? Feel good?”

She smiled at my touch.

“Was happy...♥ Elena live forever as Siwoo's sex friend♥ Only happy moment since coming this country, favorite person.”

“Good.”

I pointed at my cock.

“And this. Gotta clean it up.”

“Ah, clean friend's there nice♥”

Elena stirred her hazy body upright. She staggered toward the bathroom for a towel.

“No, not a towel.”

I chuckled. Of course, the app gave me all the sex knowledge, but I kept forgetting others didn't have it. I fiddled with my phone. Selected Elena, activated [Data Injection: Basic Sex Knowledge] and [Visual Censorship Off].

Her eyes flashed wide. The fog of censorship shrouding 'sex acts' poured directly into her brain, crystal clear. She finally understood what she'd just done—and what my cum-dripping cock meant. With censorship lifted, it all sharpened into focus for her. But instead of shame, her face flushed brighter, a beaming smile spreading.

“...Ah, this how do it?”

Elena dropped to her knees and crawled between my legs. Armed with sexual knowledge, her movements were way smoother now. She tentatively extended her tongue and began lapping up her own juices and my cum from my shaft.

Slurp, sluuuurp—♥

She looked straight up into my eyes with a sultry smile. The lonely foreign bride suffering in isolation was gone. In her place, just a bitch begging for my cum under the label of 'friend,' offering her lips, tits, and pussy.

I leaned back against the sofa armrest, gazing down at her bobbing head. It amused me—no expectations, just dropping by the village head's house, some old guy's place I'd never even seen, and getting his wife to suck my dick in their living room.

*

It'd been a week since we moved here and I got the app. On the surface, family life looked peaceful, but underneath, things were starting to creak.

I rotated through the three women regularly. Mom crawling naked into my room every night. Elena, alone in the quiet village head's house by day, lighting up with a wave and smile whenever she saw me. Even Ju-hee at the hole-in-the-wall shop by the village entrance. Each bitch satisfied my lust in her own charming way. I was living my best life.

But that was just me. The rest of the family? Hard to call it good, even politely.

Mom, Chae-eun, was still the kind, attentive mother on the surface. Cooking breakfast for everyone, prepping clothes, scrubbing every corner. But dark fatigue shadowed her eyes inescapably. No helping it—same daily chores, but every night visiting my room, spreading her pussy for my cock, left her sleep-deprived. And when no one was watching, she'd throw herself at me daytime too, tempting her son nonstop. Plus, getting fucked mid-cooking made her mix up sugar and salt, burn rice. Laundry piled up more often. She barely held up the 'devoted mother' mask, but the bliss of being her son's bitch was shaking it loose. Fatigue built, spilling into daytime gaps.

“Mom, didn't you say you'd iron my blouse?”

Seo-yoon stormed into the living room, holding her wrinkled shirt, voice sharp. Chae-eun blinked vacantly at the table, startling upright.

“Huh? Oh, sorry, Seo-yoon. Mom forgot. I'll do it right now.”

Chae-eun hastily set up the ironing board. But ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠ironing her eldest daughter's shirt lacked its old care. Even as she pressed, her eyes flicked to me repeatedly—not maternal love, just a bitch in heat's lust gleaming. If I beckoned now, she'd drop the iron, strip naked, and spread ass and pussy for me in a heartbeat. That prim mother act was just a tool to seduce her son now.

My sister, on the other hand? Seo-yoon hit new lows daily. After Dad's accident, she'd become the real head of the house. Company courtesy shifted her to 100% ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠remote work when we moved rural, but it crushed her compared to her flashy Seoul career.

“Argh, seriously! Why's the internet acting up again?!”

A frustrated yell exploded from Seo-yoon's room. She'd been wrestling sluggish satellite internet for an hour, trying to join a video call. This sleepy village house was a prison to her. No delivery, even convenience store meant 15 minutes driving. Outings? Just fields. Nights? Unnamed bugs plastered windows, creepy noises.

“Mom! No bug spray here? More weird bugs got in!”

Seo-yoon burst into the living room, stomping. Her eyes bloodshot, work stress and environment hate at breaking point. She wasn't usually this edgy, but 'head of household' weighed heavy on her young shoulders—early 20s, still too much.

“Seo-yoon, Mom'll get it quick. Don't get so mad.”

Chae-eun approached to soothe, but Seo-yoon coldly brushed her off.

“Don't look mad? How am I supposed to work here? Internet sucks, hot, bugs everywhere! Feels like I'm suffering alone!”

Seo-yoon huffed back to her room, slamming the door. Chae-eun just watched with pitying eyes.

I sat on the sofa, watching quietly. I felt for my sister too. After Dad's funeral, holding back tears in front of us, vowing she'd handle it, nodding resolute—she was amazing, worthy of respect. Even now, eyeing her with lust, that admiration lingered. I didn't want her crumbling to mere stress.

I stood.

“Mom, I'll handle the bug in Sis's room. You rest.”

I patted Chae-eun's hesitant shoulder at her door. She smiled gratefully.

“Thanks, son.”

Chae-eun retreated. I pulled out my phone. Why was Sis stressed and snappy? Simple: nowhere to lean. Wanted to rely on someone, but everyone relied on her. Whole family hanging on her. That pressure must suck.

My respected, beloved sister. And how I'd help her?

Become the master she could depend on.
