Did I Just Think of Cheol-gyu as 'Sir' in My Head?
Scritch, scritch, scritch...
"...Eut."
I'm in full panic mode, everything blurring together in a haze where I can't even tell what's happening. I lift my clothes as ordered, and even as the marker scrawls across my exposed lower belly, I can't quite grasp it. So I don't resist, don't react properly. It's just this primal sensation of something tickling my stomach...
"Haa... haa... fuck, this is so goddamn hot, heh heh heh."
Reality only catches up to me slowly, lagging way behind. What? What the hell is going on? Ever since that bastard blackmailed me with Sextwitter, my brain's been in total meltdown, refusing to process anything right. He made me stamp that filthy 'sex slave' contract... suck him off when he said suck... write in formal language when he demanded it... Then I realized he was filming, my body froze solid, he slapped me hard, terror gripped me... I was terrified of whatever he was yelling, so I stood up as ordered... and suddenly he's writing on my body... But none of it registers clearly in my head—it's all foggy, like sleepwalking, my body moving on autopilot. Like a dream, unreal, so I just drift along, puppet-like, doing whatever he says.
Ah... oh, right. Only much later does it all click in my mind. That I'm getting some kind of 'punishment' from this creep. By then, of course, I'm too panicked to fight back, and the brand's already seared onto my body.
"Heh heh... come here."
"..."
After scribbling on me with the marker, he grabs my hair roughly and drags me to the storage room next door. He's shorter than me, so I have to hunch like a lamb being led to slaughter, powerless, following him... like a female dragged into a goblin's lair...
"W-wait a sec..."
"Shut up and follow."
The 'storage room' he drags me to—it's called that, but really just a spare room crammed with unused gear and junk. Big re-taker cram school like this, they just dump forgotten crap and leave it. A dead space, pitch black like a real goblin den, unknown to most, no footsteps all day.
He hauls me to the deepest corner of that dusty, musty pit, right in front of an abandoned full-length mirror. No idea why a full-body mirror's even here... He drags me in front of it, shines his phone flashlight like a spotlight on my naked body, and forces me.
"Alright. Read it out loud."
"...Huh?"
But my head's still foggy, so I react slow.
"Hah. Still fucking out of it..."
Slap! Just for hesitating a bit, his palm cracks against my ass...
"Ah!"
The sharp sting shoots up my spine to my head, but instead of rage at him—At least it's not my face—that's the first thought, making me flinch. At some point, I've naturally submitted to him.
"Read what I wrote on your lower belly, sis."
"O-okay..."
Smack! Another burning hit. This time on my thigh.
"Master! You keep forgetting?"
"S-sorry... ah, no, I mean... I'm sorry, M-Master."
If I don't follow his orders perfectly, his palm flies. Like training a dog or cat with punishment—he's conditioning me. Making 'Master' slip naturally from my lips.
"Yeah. Don't forget. Now read it quick like I said. You agreed to be a sex slave, right?"
"...Y-yes, M-Master."
No time for complicated thoughts—I submit like livestock to his command. ...Even I think it's weird how naturally I've started obeying him... like it's my true nature...
Anyway, under his pressure, I stare at my naked reflection in the mirror. The phone light illuminates my bare body, and under that glow, on my pale, soft lower belly, bold black letters stand out starkly.
"...."
And my voice catches. It's... too much. The most humiliating thing I've ever endured...
"Read it already, you slave bitch."
But with Cheol-gyu fully perched on my head, playing real master, his coercion forces me to read the shameful tattoo on my body in a trembling voice.
"S-sex slave... in training..."
On my lower belly, right over where my womb sits, the vulgar words "Sex Slave in Training." But even worse shame creeps up from below...
♥Walking Onahole♥
♥Please Rate My Pussy Taste♥
(Stars + Review Requested!)
Like some porn forum review... begging to be rated after fucking this body... Reducing me from 'person' to 'lust relief toy'—a literal walking onahole for eating and enjoying like food... Reading it aloud myself, my body shudders uncontrollably...
...Not from anger, but this massive humiliation vibrating from my lower belly, making my erogenous zones tingle with lewd pleasure surging up again.

===== How to even describe it. Tears well up from the injustice and shame... but that degrading sensation hits me so strangely, making me doubt myself as a human.
"You love this shit, don't you, sis? Getting doodled on, insulted, raped—you fucking love it, huh?"
"Ah... no."
Smack!
"Ha-eut...!"
Shit. Behavior correction. After another ass smack, I hurry to fix my words... My ass burns and stings—definitely gonna leave handprints...
"...S-sorry, Master."
"How the fuck did you even get into college with that brain? Dumb bitch. That's why you're just a walking onahole with no value."
"..."
Forcing an absurd sex slave contract on his cousin sis. Absurd submission rules. Slaps without hesitation if I slip. Insulting my dignity... Why can't I even think to rebel against this bastard? Sure, blackmail, but...
"Last time too, you were drooling pussy juice while I skullfucked you, you maso bitch. Where do you think you can grab me, huh?"
"...."
"Good. Check yourself. You felt it when I smacked your ass just now, right?"
"Ah... no..."
Smack!!!
"H-eut!"
"See? You're disobeying on purpose to get hit, huh? Here... take this marker..."
"...?"
"Shove it in your pussy once and pull it out. That'll prove who's right."
"...!"
Under this ridiculous excuse, he orders me to fuck my own pussy with the marker right in front of him... I hesitate, get another ass smack, trudge like a cow to the slaughter... but eventually take the thick, long marker he hands me and slide it between my legs myself.
"H-eut..."
But... unlike usual, the moment the foreign object enters my pussy, my hips snap back like a bowstring—sensitivity cranked way up. My insides feel hotter than normal, the plastic marker's ridges scraping every fold as it goes in... I can't hold back, hips trembling, clit swelling taut, goosebumps everywhere, nipples rock hard...
What... the hell...?
Too intense, dizziness hits automatically. And with him forcing me to twist it a couple times and pull out...
"Haa-eut... hiik!"
I can't scream, have to clamp my hand over my mouth as moans escape, tears streaming...
Of course, the monkey bastard's totally hyped by my shameful display, barking beside me...
"Fuck... seriously. Cumming just from one shove? What a ruined slut."
"...Haa... haa."
"N-now pull it out. Pull it out, you slut."
"Hiik..."
Ah... just as he said... one shove, twist, pull... and the black marker's slick with juice, dripping from between my legs, trailing sticky strings...
So... so humiliating, my whole body flushes red... Like my body's changed. Enduring his humiliations and sexual abuse... but hypersensitive, shamefully gushing lewd fluids. Like he says, turned into a pervert slut—head spinning, I just stare blankly at the mess...
"Heek..."
"Fuck! So goddamn nasty, heh heh... Sis, embarrassed? Huh? You know you're a maso pussy slut too, right?"
He's all riled up by my vulgar state too, panting hard. His naked lower half—banana cock way too big for his height, standing rigid, foreskin peeled back, red head exposed like a dog's...
"Hah, can't hold back...!"
He grabs my waist from behind, stands close, whispers in my ear...
"Grab the mirror, stick your ass out... you fucking slut. Hurry."
"...Y-yes, M-Master..."
A tiny bit, but the resistance to calling him Master and sticking my ass out fades—just a sliver, but ominous...
Of course, whether I feel it or not, Cheol-gyu's cock plunges into me... two days straight now.
"Haa-euk!!"
...My pathetic pussy that couldn't even handle a plastic toy naturally can't endure getting raped by my tyrant cousin brother either.
=====
"You fucking... slut who loves getting raped... Master's pounding feels good, right? Huh? Say it feels good!"
"Hiik... hut... ah, no..."
"No my ass...!"
This 163cm dwarf shitstick... I bend over deep to make it easy for him to pound from behind, getting force-fucked. In my workplace, the academy. Even if it's an abandoned storage room no one comes to, it's still public... Clutching the dusty mirror, standing doggy, his disgusting vulgar insults pouring in my ear...
Yet even in this, shamefully, my body heats up wildly on its own, cumming uncontrollably...
S-stop reacting... please...!
Blackmailed for Sextwitter, for whoring... forced to get raped by him, and my body reacts like this—honestly, I'm so ashamed of myself I'm going insane...
Is... is this why... am I really a maso pervert... for real...?
Ah... creeping in... truly submitting deep down, losing control of my body, my mind, my life—becoming a meat urinal that processes his or other men's lust regardless of my will. That future feels so real... like it's actually coming, terrifying me.
"Eup!!!"
Already... I can't even control squealing like a brood sow getting pierced by Master Cheol-gyu's iron-hard cock...
....
Did I just think of him as Cheol-gyu'nim' in my head?
....Ah
