A Lewd Morning with Stepsis
I flopped onto my bed the moment I got back to my room. "Ah, this is driving me insane for real..."
No matter how you slice it, she's my stepsister! Sure, we weren't blood-related, but we'd lived under the same roof for 17 years—practically real siblings. We'd bickered every day, and once puberty hit, we'd gotten to the point where even eye contact made us cringe. Still, I'd always thought of Chae Na-hee as my genuine little sister.
And then out of nowhere, she offers to suck my dick. Hell, I even got tempted for a second there.
"Haa..."
Racked with guilt, I let out a sigh and sprawled out on the bed like a starfish, staring up at the ceiling. As I replayed the day's events in that position, all I could do was let out a hollow chuckle.
"Feels like I've gotten dragged into something huge..."
Countless questions tormented my mind.
"...Am I really stuck living in this twisted world from now on?"
Or was it just a temporary glitch? Why was I the only normal one, while everyone else's common sense had gone haywire? I had no answers yet. My head was a total mess.
As I blankly stared at the ceiling, the buzz from the beer and the exhaustion from the day's unreal bullshit hit me all at once.
"Haa..."
I just didn't want to think about anything. I slowly closed my eyes.
Guess I'll rest for now...
It had been one hell of a chaotic day.
♪♪♪♬♪♪♪
Rrrring!!! The blaring alarm assaulted my eardrums. I barely managed to pry my eyes open, and sunlight was already pouring in through the window, bright and cheerful.
"Ugh... morning already?"
I fumbled around and finally shut off the alarm, but something felt off. The blankets were warmer than usual, and there was this soft something pressing against me from inside.
"What the...?"
Something was in the bed with me? At first, I thought it was that big body pillow I'd tossed on there, but then I heard someone else's breathing, and a squishy sensation brushed my thigh.
My heart skipped—no way—as I yanked the blanket off.
"...?!"
I jolted in shock the second I flipped it back.
"Wh-what the hell are you doing...!"
It'd felt too soft and warm for a pillow, and sure enough, there was my stepsister Chae Na-hee, curled up and snoring softly.
Seeing her like that left me dumbfounded. When the fuck did she sneak in here?
She'd claimed a whole corner of my bed like it was hers, which was ridiculous enough, but then yesterday's events flashed back, and I couldn't help yelling.
"Hey! Chae Na-hee! Get up!"
At my shout, she groggily cracked her eyes open. Looking up at me with sleepy, unfocused eyes, she mumbled irritably.
"Ugh... fuck, shut up."
"Why the hell are you sleeping in my room?"
"Came to wake you up and got sleepy, so I crashed here, I guess."
Rubbing her eyes, she propped herself up. Her loose T-shirt slipped off one shoulder, exposing her pale skin, but she didn't seem to care—only I did.
...Her common sense is still fucked up, huh?
She'd always thrown a fit if I even thought about entering her room, yet here she was, casually perched on my bed. It hit me again: the world's logic was still broken. Man, this was messing with my head...
The whole world's common sense flips overnight, but no one else notices—only me. It was frustrating enough to drive me nuts. Without thinking, sharp words slipped out.
"Hey, get out of my room. Now."
"Nah, why should I?"
Ignoring me, she scooted closer. And then the thing I'd dreaded happened.
She casually lifted the edge of the blanket I was under and slid both her legs right in.
And...
"...Gasp."
My breath caught. Her foot had just touched my leg.
"H-hold on. Can you move your foot?"
"Why should I?"
With her defiant tone came a soft-yet-firm pressure worming between my thighs under the blanket. Her toes.
I tried to clamp my legs shut in a panic, but her foot grazed my inner thigh and slid higher.
What the fuck is this crazy bitch doing?!
Startled by the sudden move, I reached under to shove her foot away—but that just gave it more room to burrow in. Glancing down at the soft sensation on my lower half, I saw her bare foot rubbing over my boxers.
I was too flustered to speak. Meanwhile, her toes started pressing and rubbing lightly over the fabric.
The gentle pressure and warmth seeping through that thin layer hit way too vividly first thing in the morning—my head was spinning.
"Oppa. What's that poking my foot?"
"Hey... cut the joking around."
My voice cracked. But my body was already betraying me, reacting honestly. As my dick hardened and strained against my boxers, she smirked while prodding it with her foot.
"You hard already? It's rock solid."
"...Wh-what'd you say?"
"Your dick's fucking diamond-hard, oppa."
Her face was dead serious as she said it. No filter, straight-up blunt. Truth be told, morning wood had my boxers tenting already, but instead of pulling away, she grinned wickedly and started rubbing her sole teasingly over the bulge.
"Want me to back off a bit, oppa?"
"...Quit with the bullshit."
"Your cock's standing at full attention, and you're playing dumb? I'll milk that cum out for you."
...Talk about waking up in a shock. Every time vulgar shit like "dick" or "cum" casually dropped from her mouth, my brain short-circuited.
"Hey. Move your foot before I make you."
I tried to persuade her nicely. But she ignored me.
"Hah, look at this dick throbbing first thing in the morning. Turned on by me, huh?"
Embarrassing as hell. Getting caught tenting by my stepsister brought an indescribable wave of shame. But my body didn't care.
"Gulp..."
Her smooth thighs peeking from under her dolphin shorts. That familiar sisterly scent I'd grown used to. Her foot grinding on my boxers.
This is fucking insane...
Was she always this hot? Well, she'd been popular at school, sure. But this crossed every line.
Swish—
"Ugh, this is annoying... I'll just take 'em off."
Unfortunately, she wasn't waiting around. Leaning forward, she slipped her hand under the blanket and grabbed my pajama pants and boxers in one familiar motion.
"H-hey! Wait...!"
Despite my protests, she yanked them down without hesitation. Cool air hit my lower half in an instant, and my cock sprang up proudly in the morning light, fully exposed.
"Hah, holy shit..."
Her warm breath washed over it as she muttered—admiration or what?—sending chills racing up my spine.
"Oppa. You know what happens when you show your stepsister a boner like this, right?"
"Wh-what happens?"
"Don't play dumb. I'll suck every last drop of cum from your balls, you perv. Ptoo!"
Hot spit splattered on my glans. I looked down in panic—drool dripping from my dick courtesy of her.
"Ah..."
The lewd, obscene scent filled the air, and for a moment, I forgot she was my sister as my cock throbbed harder.
I shouldn't... this is wrong...
We'd been a normal sibling pair. Stepsiblings, but raised like blood. Nearly 17 years under one roof after Dad remarried meant petty fights and playful tussles were routine. Even at 23, a lifelong virgin bursting with pent-up lust, I'd never fantasized about her. Hell, I'd actively avoided it. Not blood-related, but still my sister—after puberty, we'd minimized contact. I'd seen her panties or bras in the laundry basket plenty, but never used them as jerk-off bait. That'd be crossing a line no siblings should.
...So why the hell was my dick getting even bigger?
"Mmm..."
Truth be told, I was excited. A twinge of self-loathing hit, but my cock was at max hardness, bigger than ever.
Fuck, this is cheating.
The sibling boundary meant nothing anymore; her actions were so hot I couldn't calm down without blowing a load.
"Then I'm doing it?"
Her hand gripped my shaft. A moan escaped me involuntarily. I should've shoved her away, but I couldn't. Pleasure had beaten reason.
"Heh... horny mutt. Look at that dick stiffening from your sister's spit. Slurp, ptoo!"
More slick spit coated my cock. The situation, the vibe, her dirty talk—it was all insanely arousing. While I sat there frozen, she spat enough to lube up, then wrapped her hand around my dick and started stroking up and down.
Slap slap slap—
Her hand shook my cock. The pleasure shorted out my brain.
"How's that? Like your sister's handjob?"
Slap slap slap!
She cupped my glans in her palm, twisting lightly like turning a doorknob, pumping away. The wet spit made obscene sounds.
"Ngh, yeah... feels good..."
Her soft hand and sticky spit delivered pleasure leagues beyond my solo sessions. My inexperienced dick twitched wildly from the novel stimulation, on the verge already.
"H-hey, wait..."
"What, gonna cum already?"
Chae Na-hee asked while jerking me, and with no breath to speak, I just nodded. She casually replied.
"Then shoot it in my mouth."
