Exactly How Many Guys Did You Fuck, You Bitch in Heat?
With a trembling voice, my sister reads the lewd graffiti scrawled across her body.
"...Milk bags... slutty whore that gets cocks hard... get pregnant..."
"Keep reading."
"...Filthy cumrag bitch..."
"More."
The graffiti on my sister's body was incredibly varied. A whore you pay to fuck already writes this shit on herself and begs customers to add more—what do you think they make of that?
"Tastes like pussy heaven... 5 stars..."
"Sis, your fuckability rating is off the charts, huh?"
"..."
"Everyone's going nuts saying it tastes amazing, kekeke."
Ah... this was the pinnacle of mental humiliation. Forcing my sister to beg OP customers to write this crap on her herself. How humiliating and degrading must that have been? And how thrilled were the customers? They must've thought she was a total hopeless slut and mocked her with vulgar, cruel scribbles bordering on verbal abuse, no pangs of conscience whatsoever.
Excited by the graffiti, I got rock hard, but I held back from touching her right away and gave an order instead. No rush now. Take it slow.
"Sis. Take off the rest of your clothes."
"...Okay."
She hesitates slightly at my command but eventually strips off her skirt, blouse, and bra, standing completely naked in my room... trembling faintly. Like some furniture on display.
I've stripped Yeon-woo sis bare and posed her like a mannequin in front of me. Not a single thread left on her exposed nude body. But the bitch still has some shame left—she's covering her pussy and tits with her hands. Kinda ruins it.
If you're a whore and a sex slave, act like it.

"What're you doing? Hands off—your master wants to look."
"..."
"Put 'em down. What shame does a whore like you still have?"
"...Yes."
Her pride clearly stung, she furrows her brow slightly... and reluctantly lowers her hands. Still a bit stiff. Even with the sex slave contract, her heart isn't fully enslaved yet.
But I don't bother punishing her more for now—just file it away and admire her artistically sculpted body on display before me.
70G cups. Massive yet perky melon tits that defy gravity. Big enough to sag a little naturally, but unbelievably firm for their size. Topped with pretty pink nipples and areolas. The stimulated nipples are slightly elongated and erect. Naturally, I reach out and grope those plump tits while taunting her.
"Fuck, these udders are huge. You know the academy kids jerk off imagining you every day, right? Huh?"
"...Ngh."
"You know? Strutting around reeking of slut, teasing them with those massive jugs—makes the poor bastards so horny they can't study."
"..."
"You're a teacher harming their learning. Feel ashamed."
I pull my hands off her cow-like tits and scan lower. A breathtaking curve at her 22-inch cinched waist that makes you wonder how her organs fit. Flowing down to wide, childbearing hips and a huge ass... nicely plump thighs propping up those hips on her otherwise slim frame, pale as marble and lusciously thick. Nestled between: thick—no, swollen—outer labia carving a deep axe gash.
As someone who's fucked her firsthand, I can vouch: that thick pussy meat cushions every thrust so it doesn't hurt your pubic bone—instead, the soft, squishy texture delivers supreme pleasure. Pubes? Kinda disappointing, but congenital hairlessness—not a single stray. I prefer a little bush, personally.
And skin white as a canvas. Pale like a white girl's, but pussy and nipples pink. A literal work of art... no, too obscenely sexual for "art." A body customized for sex, pregnancy, birth—like something out of male-oriented comics or games. Unreal.
Whoa. A real person like this actually exists. Of course, right now that white canvas is defaced with vulgar scribbles... and that's the hottest part.
If we weren't related, I'd never even talk to a girl like this. Thank god she's my cousin sis. At least I got to see her occasionally at family holidays.
But a bitch like this turns into a whore anyone can fuck for a price. Thank god Uncle's business tanked. If she'd stayed a rich girl, she wouldn't be freeloading at our place, selling her body, or getting blackmailed by me, right?
Thanks. Uncle's off somewhere dodging debts now. Thanks to his failure, the princess he raised... became a cumdump whore for anyone, and to top it off, his monkey-faced nephew turned her into a sex toy. No more New Year's money needed, folks.
If this slut knew I was defiling her in her dad's head, how would she feel?
Anyway. Back then, imagining this nude body was all I could do while jerking off. Even the first day I blackmailed and raped her... I was so desperate to fuck her I just pounded away like a maniac. Way tastier than my wildest expectations. So I came inside her three times in a row, greedy as hell.
But a day later, after forcing the sex slave contract and officially making her mine... I could strip her naked openly and savor her like a work of art, all leisurely.
No rush when I can fuck her anytime.
Instead...
"Stand straight."
"...Ugh, okay."
"Don't move. Feel the humiliation of obeying my orders out of fear of retaliation—this attitude turns me on as much as your body."
That sassy cousin sis who used to scowl openly when we were alone... now submitting to me like this? Hot.
Come to think of it, reminded me of New Year's a few years back. In front of adults, she'd act all sweet and treat me like a cute lil' bro. But alone? "Don't act familiar," face turning to stone. Her expression toward tall, handsome Tae-gyu hyung and me was night and day.
As a kid, that shit pissed me off and felt so unfair. But now this bitch trembling naked at my command... the same haughty princess who looked down on me like dirt.
I grope her ass openly, tease her areola with my fingers, rub her pussy slit... and all she lets out is a weak "Hngh..." moan, unable to push my hand away.
Ah. Can't hold back anymore. My naked sis's aroused duck-butt ass. So plump and jiggly—I had to smack it with my palm.
Smack!
"Ah!"
"Your ass is fucking perfect. What'd you eat to grow it this big?"
"..."
"Hey. What do you say when your master compliments you?"
"...Thank you, Master."
After smacking her ass, I look closer. Customers scribbled on her back and butt too. The highlight: creampie tallies. Huge ones on her ass cheeks... a whopping four.
"Sis. How many times did you do it with customers today?"
"...1, 16 times..."
What...? Even I'm doing the crazy shit of training my cousin sis as a sex slave, but... what the fuck did she just say? My brain glitches.
What? How many times...?
"What...? Crazy. No fucking way... in three hours?"
"..."
"Hey. Exactly how many guys did you fuck? You bitch in heat."
"...F-five... guys... no, I did it with five... Master."
Fuck. Even with low expectations for her chastity, this is insane. How does a person fuck 16 times in three hours? Five customers? That's guys fucking her every 10 minutes.
What a cumrag slut.
Sis blushes with shame... but that makes even less sense. A girl who knows shame agreed to a gangbang with that many men...?
"Whoa. I thought you were a dirty whore already, but you're a total insane cumrag? How the fuck 16 times in three hours? Shouldn't three hours mean just three guys?"
"...Th-that's..."
"Knew you were a whore, but this is bitch-in-heat breeding level."
She doesn't argue back at my insults. Can't, probably. She knows she's a cumrag deep down.
"It, it was... um, recently the Manager..."
Her explanation: Recently, the Manager suggested adding a gangbang option at the OP. Can't work more hours? Pack in more customers per session. Efficient profit boost from a business view... but it's her body taking the hit.
Ridiculous.
So...
"So... you jumped at the chance to make more cash per hour and said okay?"
"..."
"Yes or no."
"...Yes."
"...Fuck. No wonder there's so much goddamn graffiti."
Ah. That tiny guilt pang from humiliating her? The "am I too harsh?" sin? Gone.
Even before I made her my sex slave, she loved getting degraded by strangers. A slut born for it.
...So I can play with her however, and she'll love it more? Already filthy anyway. Novel ways to abuse her? She'll love it. No matter how rough I get on a whim? Zero fucks given.
With that thought, I squeeze her tits—her ambiguous pained moans addicting me—as I order:
"...Earlier, I ordered you to film every time you fuck other guys, right?"
"...Yeah."
"Did you?"
"..."
"Fuck, did you film it?"
She hesitates, embarrassed. But after gangbanging that many in three hours? Hilarious.
"Cumrag bitch still clinging to pride?"
I twist and yank her sticky-rice-cake tits, stretching the glandular tissue. Finally she answers.
"Haak...! S-stop... I-I filmed it... Master."
"Good. Bring your phone."
"...Here."
"Password."
"..."
"Sis. What are you now?"
"...Ch-Cheol-gyu's slave..."
"Right? Slaves have privacy?"
"...No... Master."
"Say it."
"...1112."
"Pathetically simple. Who'd you want hacking this?"
Password seized. This phone's mine to check anytime.
"Where's the footage?"
"Here..."
Let's see. How'd the customers degrade her? Excited, I play the first clip.
"...Hngh... haa...!"
A masked sis getting railed by two guys. Pussy and mouth. Double penetration. Plus the filmer—three total. My crotch tingles as I dive into the video.
