Chapter Title: 10. Doing Bad Things (4)
-----------------------------------------------------------------
I know.
This thing I'm doing,
it's not just some casual saliva application,
it has a proper name: fellatio.
"Slurp... chu... "
When my sister's not around.
Lying on my sister's bed,
wearing my sister's dolphin panties,
tying my hair with my sister's hair tie,
pretending to be my sister,
I'm slathering saliva all over
my sister's boyfriend's cock,
that brutal thing shoved right in front of my face?
...Hahaha.
Funny.
No.
I'm diligently...
giving fellatio.
Doing something lewd.
"Chu... mmph, ngh... "
To be honest...,
being alone with my sister's boyfriend
felt off from the start.
That's why I tried to keep some distance from you.
And actually, up until we started gaming together, I did.
But you kept catching my eye.
You were the first to game with me, and even as a noob, you listened so well.
I kept ending up in your arms because of healing.
No matter how hard I tried to think of you as just a 'guy friend,'
the thought of 'sister's boyfriend' kept poking at my mind.
That's when I dug into my sister's secret browser history.
Why did I choose that moment to go into 'clear browsing data'?
What embarrassing stuff did I frantically delete without her knowing?
You, Seo Woo-jin, kept teasing me into it.
One little slip, and I'd cross the line for real.
"......"
...Ah, but I haven't crossed it yet.
Sex.
I haven't done that.
Still barely safe.
...Right?
"Pwah... heh... "
I spat out the cock I'd been servicing in my mouth until just now, lay back on the bed in a sloppy pose, and let out heavy breaths.
Hah, hah, over my ragged breathing,
that cock, soaked in my saliva, twitching pleasantly, drilled into my vision.
It's not my boyfriend's cock.
Not even like some incest couple with a stepbrother's,
or some slut taking a stranger's she'd just met—
my sister's boyfriend's cock.
The more I chewed on that fact, the more ashamed I felt.
"Heup..., chu... "
I carefully gripped the base of the cock
and diligently licked along the vein under the glans.
To make it even more shameful.
Even more something
I could never tell my sister.
A secret I'd take to my grave.
"...Hey. Lee Ji-yoon."
"...What."
"Looks like you've applied enough saliva. Doesn't it?"
"...A little left. Wait."
"Where's it left?"
"You can't see from far away... up close, there's still a bit?"
The cock that should be coated in my sister's saliva
was now dripping with mine, stretching down.
I lapped it up with my tongue over and over, swallowing it,
...then turned my head to the side entirely,
engulfed the thick glans between my lips,
and with vulgar slurping sounds—
schlurp, schlurp—
coated Seo Woo-jin's cock with my fresh saliva.
...First time actually doing fellatio, but seems like I'm doing okay.
His hand had been stroking my hair without permission since earlier.
Save that for your girlfriend, not me.
I'm just the girlfriend's little sister.
"...Kgh..., kehk....... Pwah...!"
Not liking that, I shoved the cock deep into my throat a few times before pulling it out of my mouth,
and between the glossy, sticky cock and my lips, saliva threads stretched like spider silk.
Not just one or two strands, but several.
If someone snapped a photo right now and sent it to my sister, our sibling bond would shatter instantly.
Seeing that scene right in front of me made my lower belly twitch.
...Ah, anyway.
These threads, just lick them off...
......
...No no.
Break them with my fingers. Yeah.
I pulled my dazed tongue back into my mouth, wiped my lips,
broke the threads with my fingers, and stared blankly at the thick rod in front of me.
"......"
Even after all this, seeing the base still dry brought all sorts of thoughts to mind.
If he really shoved that thing all the way in, it'd wreck my insides.
Or,
What if Seo Woo-jin gets too excited, ignores my suggestion, and like a beast, slams it in—pound, pound?
Dangerous curiosities like that.
"...Seo Woo-jin. Don't just kneel there, come a little closer."
"This is enough. The base aside, it's plenty slick."
"Since we're doing it, finish it all now, you idiot. Listen."
"......"
"It's not fellatio or anything, just applying saliva..."
I swallowed the leftover saliva in my mouth and buried my face under Seo Woo-jin's lower belly, lapping diligently at his cock.
...Somehow my hands felt empty, so pretending it was a joke, I gripped his cock,
stroked it up and down with wet slaps,
rubbed the glans with my palm like I'd heard in those sex jokes from games.
"Are you sane?" he said in a voice full of pleasure,
so acting like I had no idea what it was,
all innocent,
I stroked the shaft even harder—schlick schlick.
While licking the base and imprinting his manly scent deep in my brain, I belatedly noticed something.
"......"
My saliva on Seo Woo-jin's cock,
mixed with his sticky precum,
was dripping onto my sister's pristine white bedsheet, leaving gray stains.
"......"
I stared at the sight for a moment,
roughly wiped the bed with my soaked hand to erase the traces,
then shoved the cock back in my mouth and rolled my tongue again.

"...Saliva application, right?"
"Yeah."
"Then why'd you give me a handjob?"
"...To spread it evenly everywhere."
"......"
"W-Why are you laughing? It's true, did I say something wrong? Idiot..."
Logically speaking, the moment you touch it with your hand, the saliva you'd slathered on gets taken by your palm.
Does Lee Ji-yoon think that's a decent excuse?
Or does she think even that idiotic excuse will fly because my blood's rushed to my dick instead of my brain, so I'll pretend not to notice?
Too lazy to hide my smile anymore, I gripped her slender ankle tight and lifted it up to my shoulder.
"Fine, whatever. But do it like you're really having sex with your sister?"
"...That'd be best. What we're doing is just 'sex practice' after all."
"I get that, but... you calling me sweetly like that feels way too awkward, honestly."
"...Shut up."
Like she was embarrassed inside, she covered her eyes with both wrists right after the fellatio ended and answered.
...Weird.
That "shut up,"
she never said it to me before, only to Lee Ha-yoon sometimes.
Today it feels like I'm hearing it once a minute.
Like how she texts me first when bored.
Am I as comfortable to her as her own sister now?
I squeezed her soft, squishy thighs together and thrust my soaked cock between them.
"I love you, sis."
"......"
Whispering softly,
like before.
"Why no reply? You're embarrassing me."
"...You said my acting was awkward earlier."
"You'll get better with practice. Keep going. That's how you improve, right?"
"......"
"I won't tease anymore, so just do it roughly. Or do it silently."
"...Wait a sec. Let me prepare mentally..."
"......"
"I... l-love you... Woo-jin..."
"I love you, sis."
"M-Me too... love you."
Taking her mumbled voice, cheeks flushed red, as a side dish,
schlick,
schlick,
schlick.
Gently.
I thrust my sticky cock diligently between her pale white thighs.
...Of course, not shoving it all in,
just exactly as much as Lee Ji-yoon said.
Not letting it poke out past her thighs,
carefully.
But still,
a bit aggressively.
"...But sis wants rape play, right?"
"...Why bring that up...?"
"Saying 'I love you' feels kinda weird now that I think about it."
"...It's just play for now."
"And for rape play, isn't this too timid thrusting...?"
"Eek... w-wait... "
Slam, slam, slam.
Replacing the sticky schlicking sounds from moments ago,
the slapping of my lower belly against Lee Ji-yoon's thighs
filled Lee Ha-yoon's bedroom.
Under my downward gaze,
her saliva-slick glans popped out with each thump.
Her lewdly spread thighs
got squished and distorted—squelch squelch.
Startled by her suddenly rocking body, Lee Ji-yoon
peeked between her thighs from under the wrists covering her eyes.
I slammed my cock in freely.
"This is how you thrust, right?"
"...D-don't know...! That's not my thing..."
"Think of me as Ha-yoon sis. ...We're in the middle of 'sex practice.'"
"......"
"Not your tastes—what do you think Ha-yoon sis would like?"
"......"
Lee Ji-yoon, eyes covered, barely managing heavy breaths.
After a quiet moment, she gulped and squeezed her thighs while speaking.
"Th-that might be better... shoving it in by force all the way..."
As if she had no real interest in it herself.
Like she was just helping a friend practice.
"You can borrow my thighs..., so... practice."
Even after eyeing my cock peeking out from her thighs, swallowing hard.
So shameless.
...That look,
crudely put, was fucking hot.
"Then, like before."
"Ngh... "
Me too.
"I love you. Ji-yoon..., no, Ha-yoon sis."
"......"
Deliberately dropping Lee Ji-yoon's name,
I pounded my blood-engorged cock into her saliva-smeared thighs.
"...Reply a little. It's embarrassing doing this alone."
"Th-that, my name... I heard it..."
"Obviously a slip. ...You and your sis differ by one letter."
"...When you have sex with sis, never do that."
"I'll try."
As if saying I wanted to thrust into you like this,
not your sister,
but you.
That I wanted to ram this cock into you,
dropping Lee Ji-yoon's name.
I hugged her thighs, too busy covering her eyes with her wrists, and pounded between them until the wet slaps echoed loudly.
While suppressing the heavy ejaculation urge building in my balls.
"Hoo..."
"Eek..., ngh... "
Her legs twitching each time my lower belly met her thighs.
Following that curve downward, I saw
my fully erect cockhead nearly reaching her navel, bulging out.
Slowly lifting my gaze up,
her emerald eyes peeked at the glans from under her "covered" wrists.
...Well, yeah, it's leaking precum like it's desperate to cum already.
Probably worried when the semen might spurt out.
"......"
Tissues were right by the bed anyway...
It's fine.
Suppressing the pleasure throbbing at my cock's base since the fellatio, I
suddenly pinned my lower belly against her sweat-soaked thighs and exhaled.
"...Wh-what? Seo Woo-jin, st-stop...!"
Onto Lee Ji-yoon's pale belly,
her shirt rolled up to her chest,
Lee Ha-yoon's pitch-black dolphin panties she'd changed into.
So I could dump my jelly-thick semen there.
"What if you cum here...! No, stop, stop cumming...! What if it gets on sis's bed?!"
Spurt,
splurt,
spluuurt.
Splurt...
Her hastily outstretched palm caught a load of semen.
Startled by the heat?
Lee Ji-yoon, feeling semen temperature for the first time, flinched and pulled her hand back.
...Thanks to that, the following thick ropes splattered freely, messing up her belly completely.
"......"
"......"
From her pale lower abdomen to her navel.
Below that, even the dolphin panties she'd borrowed from her sister.
Thick globs of sticky semen splattered everywhere.
Lee Ji-yoon, treated like tissues in place of her sister,
stared blankly down at her body
until my ejaculation ended.
A total mess.
Defiled with semen.
