Sis, What Are You Doing in Cheol-gyu's Room Every Morning??
I'm a prostitute working OP. Of course, I was originally born into a well-off family(?) and raised without knowing any hardship, just a normal rich girl. But when Dad's business went under, I ended up living in a goshiwon for the first time in my life, and eventually Uncle took me in so I could settle here. Still, I felt like I had to earn my own money.
So I tried part-time jobs and this and that, but nothing suited me... Then came the offer... a kiss room. A pleasure joint where you make money kissing other men. I agonized over it at first. Naturally, having been born and raised as a rich girl without any struggles, I couldn't just jump into something like that. But I fell for the sweet talk—no sex required, just kissing—and ended up taking the job...
"Hey. You can't just do actual kissing and call it a day."
"Huh...? But Manager said at first that just kissing would be fine..."
"It was fine back then. But people need some give and take, right? You think I'd be happy if you really just kissed and stopped? The other girls at least give a handjob finish after some grinding?"
"No..."
"Ah, I'm not forcing you. Just know that if you stick to kissing only, your hourly pay and pickup rate will tank. That's all you need to get. So, what'll it be?"
It might sound like an excuse, but I didn't sell my body from the start. I only began at the kiss room this April. Just four months ago. Unable to resist the Manager's half-threats, I started giving handjobs to clients, and as time heals all wounds, it became natural to take them in my mouth too. Then I ran into a university junior at the kiss room... got half-blackmailed into fucking him. And the Manager found out about that... so I got scouted to OP.
Obviously, my first client was disgusting, revolting... I wondered how I could keep doing this. You know the type who come to OP—eight or nine out of ten have something wrong with them, right? So at first, I really thought this wasn't for me—
But now? Doing it over time... I got used to it, and once used to it... I could even enjoy it a little in my own way. Sometimes a client with good chemistry would come along, and I'd cum too...
So what I'm saying is...
"Haa... haa... Sis's mouth-pussy feels so good!"
"...Fuck, you're such an idiot. Mouth-pussy, mouth-pussy, shut up."
"...What can I do? It feels good."
"Hah. No wonder you're a total loner otaku."
Sucking Cheol-gyu off for money. Doing it right in the house with the whole family around. Even that... after a few days... I adapted.
At first, sucking off a loser like Cheol-gyu filled me with massive self-loathing, and just being blackmailed by him was huge stress. But familiarity is scary... Just a few days passed, and the revulsion from sucking his unwashed, filthy dick... mostly faded.
And—
"Here. 200,000 won."
"..."
Even taking money from him felt like utter humiliation at first... Now it's as routine as taking it from OP clients. It's humiliating that I've adapted, but what can you do.
But it wasn't just me getting used to it. Cheol-gyu got bolder too, making all sorts of demands. Now he casually slips his hand under my clothes, groping my tits, my stomach, even my pussy... Ugh... If it weren't for the blackmail, I'd kill him...!
"Sis!"
"...What now? I already sucked you off."
"What if... I pay extra..."
"...For what?"
"Heh heh... Sell me your panties, Sis?"
"What?"
What kind of pervert shit is this?
"What are you gonna do with my panties?"
"Just... heh heh."
That monkey bastard grinning sleazily. As if I don't know what creeps like him do with women's panties.
Overwhelmed with pathetic disgust, I snapped at him.
"Hey, is your money rotting away or something?"
"Yeah. Got plenty."
"..."
True. His dad—my uncle—is the director of a major women's hospital right in the heart of Gangnam. Living in this 4-billion-won apartment is "frugal" for them, so yeah.
Of course, I lived similarly when Dad was at his peak... Back then, swiping millions on the card he gave me was no big deal.
Anyway, hyped by my reaction, Cheol-gyu starts bragging unprompted.
"Sis, Sis. You know I actually have coins because Tae-gyu hyung told me to?"
"What? Coins?"
"Yeah. New Year's money I saved up—Dad said do what I want with it. Tae-gyu hyung said instead of buying a computer, invest in coins."
"...So you bought coins?"
"Yeah. It was about 10 million back then, I think... Now it's around 35 million? Or something."
Hah. This loser has that kind of cash. I couldn't keep a straight face; my expression twisted.
"...Must be nice."
"That's why I'm saying..."
He spoke in a sly whisper... while slipping that monkey paw inside my panties.
"...Get your hand off."
"Just do it with me once?"
"...Hah, I said no."
"Why not? I'll pay a lot."
...This fucker... Treating me like a full whore now. Shit...
But no matter how important the money, I didn't want to spread for him.
"Dream on. No matter what, I ain't opening my legs for you."
"...Th-then at least sell me your panties."
"..."
I wanted to reject even that pervy demand... But if I did, he'd throw a tantrum and waste my tight schedule.
Knock knock knock—
Sure enough.
"Hey. Let's go."
"Yeah! Just a sec!"
My little brother, always right on time for academy prep. Because of Jin-woo.
"Hurry up. Jin-woo's waiting, heh heh."
"Ah, fuck..."
And Cheol-gyu, knowing that... Exploits Jin-woo waiting outside—might come in and get suspicious—perfectly.
"...You pervert fuck... This panty's 100,000-won."
"Wh-what? What panties cost that much?"
"...200,000 won."
"What...?"
"Take it or leave it."
Money to burn, huh. Time to play hardball.
No way he'd actually buy panties for that price...
"Deal. Here."
"...?!"
For real...? He's buying it?
=====
Yeon-woo Lee's little brother, Jin-woo Lee, had been feeling a bit off lately.
Is something up with Sis?
Her expression had been dark these past few days. Of course, Sis was a master of composure—no one else would notice—but as her brother, he could sense the subtle difference.
And one more thing.
What the hell do they do every morning?
He hadn't noticed before, but lately, after breakfast, Cheol-gyu and Sis would go into his room and do something. It took his oblivious self a while to catch on, but that meant even he could tell something was fishy.
What reason could there be to go into that room every morning...? Teaching him? Private lessons?
But straight-laced Jin-woo couldn't even imagine the truth. At most, he figured since Sis was an academy instructor, maybe she was giving him extra lessons—model student thinking, nothing more.
No way he could picture his one and only blood sister sucking off their cousin Cheol-gyu in there and taking money like a whore.
(Though he was right that she was "giving" something!)
So it felt off, but being polite, he wouldn't stoop to eavesdropping at the door.
But—
Hah. Fucking fidgeting forever. When are they coming out?
For Jin-woo, who couldn't function without his Kant-like rigid daily routine, it was infuriating.
"Ahem!"
Knock knock knock!
This time with more feeling in the knock.
"Ah, got it!"
A shout from inside. Sounds of frantic... dressing? Then—
"Haa... haa, alright already."
The monkey-faced one burst out the door crack, face drenched in sweat as always.
"What the hell were you doing?"
"Huh? Oh, heh heh..."
That expression. Subtly smug, like he wanted to brag but couldn't—the punchable look of someone holding back.
On that ugly mug, no less. Even model Jin-woo felt the urge to deck him.
"J-Jin-woo. Don't we gotta go to academy?"
And Sis emerging late, face flushed.
"Sis?"
"Yeah?"
"Your lips... Hold on."
Jin-woo reached for her lips.
To brush off some weird hair-like thing stuck to the corner.
"Wh-why??"
"Yeah... Looks like some hair or something?"
"Huh?"
He examined the strand closely. Curly hair.
"Ah, wh-what. Must've gotten hair on me by mistake, ha, haha."
Suspiciously flustered, cheeks suddenly red, she snatched the strand from his hand.
"Anyway... What've you been doing there lately?"
"Huh?"
"...Yeah."
"Why do you go to Cheol-gyu's room every morning?"
"I-I..."
"...Uh-huh."
Weirdly tongue-tied, both of them. Even thick-headed wall-like Jin-woo would suspect something by now—
"Maybe giving Cheol-gyu some morning study help?"
But rational Jin-woo couldn't imagine beyond this rational scenario.
"Ah, haha! Y-yeah... T-teaching him studies!"
"Y-yeah... Th-thanks, Sis, haha."
"...?"
Weirdly sweating buckets, both. Jin-woo tilted his head but checked his watch and spoke urgently.
"Hey. Hurry up. We're already late."
"Ah, y-yeah. Haha. S-Sis, teach me 'again' tomorrow, okay?"
"Y-yeah... Ha, haha."
=====
"Ah. Hey, I left something behind."
"What? You've never forgotten anything once."
Distracted by what Sis was up to? Jin-woo realized a bit late he'd left his pencil case in his room—something he never did.
"Wait here."
"Hurry back."
Conveniently remembered right as the elevator hit the first floor. Safely stopped it before it closed.
Pressed the button again and headed back home thoughtlessly. Well, not entirely thoughtless—solving math problems in his head.
"Gotta ace the mock exam this time."
Muttering that lame crap, Jin-woo re-entered his room and saw Sis inside.
Yeon-woo was bent over in dolphin pants that exposed half her ass (sometimes he thought his own sister dressed too sluttily), rummaging in the under-bed drawer.
"Sis."
"Huh, why?"
"Forgot something."
"You? Weird."
"Yeah..."
Grabbing his pencil case from the desk without thinking, about to head back to academy—
He saw it.
"...?"
Her on her knees, bent over... ass raised way higher than needed.
The too-short dolphin pants riding up tight—revealing half his blood sister's pink pussy through the gap, wearing nothing underneath.
