Sword-Fighting with Sis
"Ugh, is it over?"
"Yeah."
As I stepped out into the living room, Mom and Noona, who had been sitting awkwardly on the sofa, stood up to greet me with stiff smiles.
"Eunbi should be fine for a while now. I gave her a good, thorough release."
"R-Really?"
I slipped onto the sofa and fidgeted with my fingers for a moment before speaking up.
"Who wants to go next?"
"..."
Mom and Noona bowed their heads slightly, glancing at each other hesitantly.
"I'm fine, so Yuyeon should go first."
"N-No, I'm okay too. Mom, you go ahead."
The two of them kept deferring to each other, insisting the other go first. At a glance, it might look like they were trying to push it off on one another, but the bulging tents in their crotch areas told a different story.
This wasn't going to get decided anytime soon, so I made the call.
"Let's do Noona first."
"Ah, y-yeah?"
Noona flinched at my words, her eyes darting to mine like a puppy caught in the act, avoiding and then meeting my gaze before finally nodding.
"Okay..."
"Let's go to your room, Noona. Mom, just wait a bit longer."
"Got it. Take good care of your sister, sweetie."
With my whining skill, the atmosphere settled in an instant, and Noona obediently let me lead her into her room.
Click.
The moment I let Noona enter first and closed the door behind us.
Conquer Noona's Dick Files!
Noona's arousal is lower than her little sister's, but she's already quite accustomed to futanari masturbation and pleasure. To drop it to normal levels, you'll need at least four ejaculations.
So, let's conquer Noona's secret files stuffed with futanari bochu sibling incest porn. The more shame and embarrassment you inflict by watching her dick files together, the easier it'll be to lower her arousal.
Additionally, doing sword-fighting face-to-face will grant a new skill.
Sword-Fighting — The act of rubbing dicks together while staring into each other's eyes.
Please accept~
Ngh, wh-what the hell is this status window trying to make me do?!
Unlike with Eunbi, where it popped up midway after I helped her out, this quest appeared the second we entered Noona's room. Eunbi only needed three, but Noona requires at least four. No way a simple handjob could handle that.
Haa... It'll be a bit embarrassing, but watching her files together is one thing—s-sword-fighting? Telling me to do something that perverted with my own sister? As if I could!
I mentally screamed 'reject!', but my eyes kept drifting to the promise of a new skill. What could it be? Probably not some combat thing out of nowhere—it had to be something to relieve our family's lust and keep us safe. Earlier, Eunbi's arousal dropped to 54, but one dick kiss bumped it up by 3 to 57. Just 3 more and it'd hit 60, the caution zone. I'd barely finished Eunbi, and once Noona's done, it'd be Mom next.
A skill... ugh, one more skill would be great, right? Y-Yeah, that's it. Sword-fighting... hnn. Just close my eyes and do it once...
"Eunwoo, what's wrong?"
"Oh, uh? New quest just came up. But it might be kinda embarrassing. You okay with that, Noona?"
"Hmm, I'm fine. You're working so hard for my sake, after all."
Even though we're only two years apart, Noona's always had that big-sister vibe, putting me first. She's smiling brightly now, pretending it's no big deal for my sake. How long can that radiant smile last...?
"...Gulp. D-Do we really have to do it like this?"
"Yeah. To finish quick, we gotta follow the quest. So, unlock the password."
Noona's hidden secret file [Thesis1a]
At my firm tone, Noona's trembling fingers started tapping the keyboard.
Tap tap diggle ms dnfl dms...
"But what's this even mean? It's so long, and you're not looking at anything—just typing?"
"Ah, w-well... Curious...?"
"Kinda, but it's hard to say—"
The thought hit me: making Noona as embarrassed and ashamed as possible would lower her arousal faster. My words shifted.
"Yeah, I wanna know. What is it? A straight-A student like you probably picked something fun and unique, right? Am I right?"
"Ngh, th-that's..."
Tap, tap tap. Her typing slowed drastically as she spoke in a quivering voice.
"M-My beloved Eunwoo. I want to suck your little dick."
"Wha—suck my what?"
"Suck your little d-dick. That's the password. Ngh, sob."
Her answer blew past my wildest guesses. While I sat there stunned, the password unlocked, and the files opened. The screen flooded with a massive horde of porn. Second time seeing it, but the sheer volume was still overwhelming.
Hoo... Here we go. Get it together, Baek Eunwoo.
I scooted right up next to Noona and scrolled down.
"First time I saw this, the sheer amount shocked me. I have some porn too, but nothing like this. Hmm, Noona speaks English and Japanese fluently, so maybe that's it? Porn's way hotter when you get the story or dialogue—subs matter, and mangas without 'em are a total turn-off."
"Th-that's..."
Scroll, scroll. Click.
"Watched this one—pretty hot. Futanari big sis has anal sex with her bochu little bro behind their parents' backs whenever they get a chance. Hearts in their eyes, screaming 'I love you,' clinging tight as they cum together... hnn. Imagining myself as that little bro made my ass tingle."
"Haa, haaa."
Scroll. I kept going, down to her darkest secrets.
Click.
"I want to fuck Eunwoo. I want to kiss Eunwoo. Grab that tiny cute face and deep-kiss him. Rub my monstrous huge futanari dick on his bare belly while tongue-fucking his mouth sloppily♥"
"Hnn, stop. Eunwoo, please stop..."
Reading aloud what she'd written about me mortified her. She never imagined this day would come when she typed it. No pretense—just raw, filthy, stimulating words.
"I'll torment your prostate. Rub that male weak spot with my big glans♥ Cum your brains out, cry and sob 'ang ang.' I'll pound your ass-pussy so hard it won't close, so spin that cute dick like a top and go nuts. Scream you love Noona while you feel that bowel reflex kicking in!"
"Ngh, nuu..."
"Noona, take off your pants. Panties too—spread your legs and jerk off. Listen to me read your own stuff while you shake that dick with both hands."
With my whining skill layered on, Noona meekly started stripping. Pants down, panties down—
Twang!
Her vicious cock, soaked in precum, sprang out proudly. Twitch twitch! Just like Eunbi's, it throbbed wildly up and down. Squish, squiiish... Sticky precum sounds as her masturbation began. Hips thrust forward, legs splayed wide, both hands barely enough to stroke that monster—futanari jerk-off in full swing.
I fed her ASMR of her own desires, piling on the shameful questions.
"You really wanna finger my asshole and prostate-train me? Tease me for hours on the edge till I'm bawling 'please let me cum,' then cover my whole body in your cum?"
"Hnn, y-yes. Aaa..."
"Shove your dick balls-deep in my ass-pussy, pound away till you flood it with hot stinky cum? Never knew you thought like that, Noona. You're always so gentle, smiling bright, hugging me tight. Look, it even says 'I love you' here. Is this your way of loving your one and only little brother? Ravaging his ass mercilessly?"
Squelch squelch, squelch squelch!
"Haa haa, sob. Sorry, sorry, Eunwoo."
The more I degraded her from my mouth, the faster and harder her hands pumped her dick.
"But how'd you know my dick's so small?"
"Hnn, uh, j-just a fantasy, figured maybe..."
"'Cause my body's small and cute? Pale, soft skin like a girl's? Yeah, like the bochus in these mangas? Figured since it's a cute bochu, the dick must be tiny too?"
Squiiish, squeeelch! Squelch!
"Haaht, heee♥ Th-that's."
Noona couldn't answer easily, but her hands never stopped furiously stroking.
"Lemme show you."
"Haa haa, eh?"
I pushed my chair back, stood, and dropped my pants. In a flash, pants and undies hit the floor, exposing my lower half. Smooth hairless pretty legs, hips almost girly, perky ass. And unlike Noona's, my pale, milky—but tiny—dick. Erect yet still foreskin-covered, smaller than a finger, a pathetic little nub. Too small for full-hand jerks; had to pinch fingers carefully even to rub it... a total male-failure cock.
"Haa haa, ngh. Noona, stand up?"
Noona and I faced each other, dicks erect. Her blushing face matched her cock throbbing fiercely, nearly brushing her belly. Twitch, twitch! Throb throb! Mine hung limp downward despite being hard.
"Noona, you know what sword-fighting is?"
"Huh? N-No, what's that?"
Noona, swallowing hard at my dick, gasped in lewd surprise at my next move, letting out a filthy whimper.
"Didn't know either till the quest. It's, like, this."
I grabbed her powerfully erect cock—nearly belly-touching—with my right hand, my own limp one with my left, and rubbed the glans together, clashing tips. Then...
"Ngh, haa. Uuung. Shake our hips like this and fight dick-to-dick... that's sword-fighting..."
