How to Apologize to Your Stepsister
My stepsister slammed the door and stormed out of my room. Flustered, I shut down my computer and chased after her, but she'd already shut herself in her room by then. I knocked on her door anyway.
Knock knock.
"Hey, why are you so pissed?"
No response. We'd bickered over little things plenty of times before, but she rarely got this mad. I was a bit thrown off. Was she really that upset about me selling my panties?
"What's wrong? Something happen?"
Mom, who'd been sipping coffee in the living room, overheard the commotion from Na-hee's room and gave me a long look. I felt a little embarrassed, but I started explaining the situation slowly anyway.
"Well... on my way back from the gym, I sold my panties to some girl."
"...You sold your panties? Like, the ones you were wearing?"
"Yeah."
"Oh dear... no wonder Na-hee got mad."
Mom's eyes turned serious as she heard my answer. Seeing that, I got a little flustered. ...Did I screw up for no reason?
I'd assumed selling panties was totally normal in this twisted world where common sense was all lewd and shit, but maybe there was a problem with it? I'd just been trying to make a quick buck...
Mom usually forgave my screw-ups with gentle understanding, but now she was staring at me with a grave look, and I realized I'd made a huge mistake.
"Se-hyeon, honey. Are you short on cash lately...? Want Mom to give you more allowance?"
"N-no, I'm fine..."
"Then you didn't borrow money from anyone, right? If you're having money troubles, you have to tell Mom. I'll help however I can..."
She looked genuinely worried. I shook my head frantically.
"It's not like that!"
"Okay, good... But still, you should've saved your panties as jerk-off aid for your little sister. Where else is she gonna find jerk-off aid as good as panties soaked in her big bro's cock scent?"
"Uh, r-really...?"
"Yeah. Na-hee's at that age where her sex drive is raging, right? She probably wanted to sniff your panties and masturbate, and then you go sell them to some other girl. Of course she's bummed out."
Listening to Mom's calm explanation, I finally got what my fuck-up was. Panties that should've been Na-hee's jerk-off aid—I'd sold them to another woman. From her perspective, it must feel like someone stole her masturbation side dish.
"You're an adult now, Se-hyeon, and you'll be busy fucking girls outside, so it's natural you'd neglect family a bit... but you could've at least saved your panties for your sister's wank fodder, yeah?"
I got the gist of how things worked here. Apparently, it was common sense for a big brother to let his little sister use his worn panties as jerk-off aid.
Think about it. In a world where common sense was lewd as hell, selling my panties to some random chick was basically inconsiderate as fuck to my stepsister, who needed to get off every day. Worst case, it could come off like I didn't give a shit about her sex life—like I was a trash brother.
Hmm... yeah, that tracks.
But that's not it...!
This common sense was really hard to adapt to. I sighed and said,
"Haa... I messed up."
"It's okay. Just let your current panties soak up that cock scent and give them to her later. But if you wanna apologize to Na-hee properly, why not just go in her room and fuck her brains out?"
"W-what?"
Even as I stammered in shock, Mom's tone stayed as warmly affectionate as ever.
"She's mad 'cause she doesn't have jerk-off aid, right? So wouldn't the best way be for her big bro to take care of her sexual needs?"
"Uhmm..."
Mom's reconciliation method was straightforward. I'd recklessly sold off panties meant to be her jerk-off aid, so as her big brother, I should take responsibility and handle her urges myself.
It didn't sound wrong, exactly... but sex with my stepsister? Could I even pull that off?
"I'll think about it."
Na-hee showed no signs of coming out, so I figured I'd talk to her later. I was heading back to my room when—
Bang! The door flew open right on cue, and out came Chae Na-hee.
She shot me an irritated glare as I stood in the living room, grabbed a drink from the fridge, and headed back to her room. Mom saw it all and gave me a knowing smile with meaningful eyes.
Apologize now, why don't you?
Her gaze seemed to say. With a sigh, I had no choice but to call out to her.
"Haa... Hey. Chae Na-hee."
"What?"
"Let's talk for a sec."
"..."
She ignored me and tried to head back to her room. I followed and said,
"Sorry."
"Sorry for what?"
Only after I apologized first did she stop and stare at me. Her face was still blank, but at least she seemed willing to hear me out.

I took a deep breath and said,
"Look... I'm sorry for selling those panties you were supposed to use as jerk-off aid without asking. I won't do it again, so cool off, okay?"
"...Come to my room first if you wanna talk."
Did she sense the sincerity? Her voice softened a bit as she suddenly turned and told me to follow her inside.
I trailed after her quietly. Once in her room, she plopped on the bed, crossing her bare legs peeking out from her dolphin pants.
"So. You're sorry, so I should just get over it?"
Her tone was a bit scolding, but unlike before, her expression had eased up a lot. It wasn't that she was still mad—it felt like she was pretending to be pissed to squeeze something out of me.
Like a classic tsundere ploy? After nearly twenty years together, I knew her tricks inside out.
But I'd fucked up first, so I nodded meekly.
"Yeah. My bad, so forgive me."
"How much did you sell your panties for?"
"...200,000 won?"
Her brows furrowed at my honest answer.
"You sold them to some random bitch? I don't care if you fuck pussy left and right outside, but you could've saved your panties at least?"
"Sorry. Wanna split it? I'll give you 100,000."
"Haa, I don't need it."
She pouted and tapped her foot sulkily. My eyes locked on her bare legs stretching from the dolphin pants, and she started poking my thigh with her foot.
"So, is a sorry all I get?"
"No, you said you don't want the 100,000. Or do you want something else?"
"Why? If I do, you'll give it to me?"
I nodded for now.
"I'll hear you out first and decide, but if it's something I can do, sure."
"Really? No take-backs later?"
Hearing that, she suddenly grinned—way too brightly, almost suspiciously—and nodded.
A flicker of unease hit me at the abrupt mood swing, but then—
"Here."
She spread her legs wide open.
No explanation—just bam, legs apart. I stared blankly, wondering what the hell, and caught her smirking slyly.
"Lick it."
"Lick what?"
"Lick my pussy."
She demanded a pussy lick so casually. Doubting if she was serious, I looked at her, and she snapped irritably,
"What, you don't wanna?"
"No! Hold on! Why the hell should I?"
"You just said you'd do whatever I want."
"Yeah, but..."
This world's common sense had warped lewd over the past two days—I'd seen it with my own eyes. Siblings reconciling like this didn't even feel weird anymore.
But that didn't stop my brain from short-circuiting. She had zero patience, though.
"Hurry up and lick."
"...Fine. There."
I had no choice but to approach her.
The moment her lower half in those dolphin pants filled my view—bare legs and all—my crotch reacted on instinct.
She smirked at that, lifted her legs a bit, and I pretended to resist as I started peeling off her dolphin pants.
Swish—as they slid down her hips, her skin emerged so white and smooth it almost felt wrong. I couldn't help but gasp a little.
This girl's skin is insanely pale... Must be Mom's genes—flawless, not a single blemish.
I pulled Na-hee's dolphin pants all the way down, and that's when I froze. Of course—no panties inside.
"Ah..."
I was speechless for a second. I'd planned to take off the pants first, then brace myself for the panties.
But suddenly, her pussy was right there, and my brain blue-screened.
It's pretty...
Pink color—gorgeous. Skin so soft-looking. I leaned in closer, and the warm, musky scent from her pussy thickened, filling every breath with her aroma.
My stepsister's pussy smell... For some reason, inhaling it made my cock throb painfully hard.
Unable to hold back the surging lust, I timidly stuck out my tongue and gave her pussy a tentative lick.
Lick...
Her smooth, hairless pussy mound had this exciting tang to it. The mix of a girl's soft, sweet scent and raw lewd musk was dizzyingly stimulating.
Gaining confidence, I licked more aggressively.
Slurp, smack... Schlick...
"Ahh, haa... Lick every corner deeper."
Schlick... Slurrrp...
"Yeah, like that... Hah, fuck... so good..."
That potty mouth again... I'd told her a million times a cute girl like her shouldn't swear, but she never fixed it.
"Deeper inside... suck it more..."
She pressed down on the back of my head as she said it. I didn't resist, diving in deeper.
Smooch... lick...
"Yeah... haa..."
Her slutty moans. The sweet taste on my tongue tip.
Slurrrp...
With all my heart for making up, I used my full lips to worship her pussy devotedly, then thrust my tongue deeper to stir her most secret depths.
