Cheol-gyu's Story
"Hey. Where'd you go?"
"Huh? To take a shit."
"What kinda shit takes an hour...?"
It wasn't until I heard the guy sitting next to me that I realized an hour had passed. Time really flew that fast? Still a bit dazed, I mumbled some excuse to him.
"Uh, constipation."
"Constipation for an hour? You were slacking off, weren't you? Dude, the CSAT's right around the corner."
"I know, asshole."
"Jeez. You know English direct lecture starts in ten minutes, right?"
"I said I know..."
This guy's not even my wife, but he's worrying about my grades. His name's Jin-woo. My cousin, same age as me. He's been living with us since the start of the year. Unlike me, wandering aimlessly, he's got a clear goal—medical school—and he's steadily chipping away at his time to make it real. Hell, even a guy like me has to admit he's impressively cool. And just now, I came back from raping his big sister.
Mabong Self-Study Re-taker Academy. It's basically a self-study spot where you listen to online lectures, but since last year, they've hired experienced instructors for direct lectures in key subjects like math. So the top-tier course is direct lectures plus online self-study, while tier two is just self-study with access to human teachers for questions. The director's my dad's friend, so Jin-woo and I get special discounts to take math and English direct lectures.
"Alright! Look closely at the first sentence. -A cell is 'born' as a twin when its mother cell divides, ①producing two daughter cells.- Comma, then ing. Classic participial phrase spot. The subject of the main clause, its mother cell, divides while producing two daughter cells, so it's clearly active. Pass."
Normally, we study in assigned seats in a reading-room-like 'self-study room,' listening to online lectures on schedule. Top-tier, or rather comprehensive class students, move to the lecture hall at designated times for direct instruction. That's why Jin-woo and I are listening to Square Teacher's English grammar lecture.
"Second one. -...each grows until it becomes as large as the mother cell ②was.- The daughter cell grows as large as the mother cell was. Comparing the daughter cell's state (becomes large) to the mother cell's past state (was large). It takes a stative verb like becomes, not a general verb like grows, so was is correct. That's the examiners' first trap. Impatient kids see grows and waste time debating did or pick the wrong answer..."
Honestly, I have no clue what the hell he's saying. Square Teacher (yeah, his head's literally square like a block—how does a human even look that angular?), spitting as he explains furiously, but CSAT English grammar... was it meant for humans to understand? Or just torture? Not 'cause I'm a blockhead with English grade 6— even native speakers struggle. Why do I have to listen to this?
Of course, the Lee Jin-woo next to me, that inhuman study machine who probably cried "Hello, ma'am" politely the moment he popped out of the womb, is fully focused on the passage and the instructor, without a single stray thought.
...Jealous.
And honestly, a bit resentful too. What I can't do, but he can. Concentration, vocab, comprehension, reasoning... brainpower gap from the start. No, not just brains—mental grit, that so-called perseverance, that's the real kicker. While I'm rotting my re-taker life on games, comics, porn, shorts... instant dopamine hits, he's sprinting full throttle toward med school without glancing away.
I'm a 10-million-won Chinese compact; he's a 300-million-won Porsche. Innate stats, total capacity—just different leagues. Enviable, jealous-making, and deep down, I can't help admitting the thick sense of defeat he gives me. That's talent, huh? They say studying's 20% effort, 80% genes... Wait, if it's genes, why me? Dad's a doctor, big bro went to S University—why am I the only average grade 4?
...No point dwelling; it'll just make me hate myself more. That gloomy inferiority complex, triggered again by comparing to him... My stressed brain, like always, can't focus on the boring English anymore, starts craving dopamine. So I replay what happened in that dim warehouse earlier... no, these past few days, the insane stuff with my cousin sister.
My cousin siblings crashing into my dull gray life. Especially cousin sister... Yeon-woo Lee. Yeon-woo sis... Number one in my head for years, secret crush, jerk-off fantasy. That sis I secretly loved. We'd see each other once at holidays, but my heart raced every time. But as cousins, she stayed just a head fantasy for ages...
Then, first time trying to lose my virginity, I stumbled into an OP. Saw her there, getting fucked by a friend. That's when my boring gray life started shaking up big time.
Real shock. That perfect Yeon-woo sis turns out to be... a whore who'll spread for anyone with cash?
Unlike me, no rationality or fate with women, she was haughty, neat, elegant, innocent... every good word for praising a woman fit her perfectly. My one-sided crush cousin sis... a whore? Even if uncle's business tanked, no issue affording food... doing whore work for a bit more cash?
That moment. Remembering when I found out she works OP, my heart still pounds uncomfortably. And her, who despised me, grimacing like she was dying as she was forced to suck my dick. Took a bit, but first time popping cherry, and that third-rate fantasy of turning sis into a sex slave became reality.
Just two hours ago, that thrilling memory of forcing her in the dark warehouse... excited, I glance slyly at her blood brother, Jin-woo, whom I just raped—perverted hobby, but...
He has no idea, right? That his sis is a slut... no, a real whore who spreads for cash?
Thrilling just thinking it. This guy plodding straight ahead, ignoring everything... if he knew his only sis is a whore? And worse, exposed as a whore, blackmailed by cousin bro-me into becoming a sex slave, spreading pussy for a measly 20,000 won...?
Fuck...
Imagining it gets me so hard it hurts... Even after shooting in the warehouse, precum's soaking my panty front from the stiff dick.
Doesn't know I fucked his own sis... just studies, clueless.
Of course, I don't hate Jin-woo. Good, serious, diligent. Why hate? Just— that iron mask face of his, different from a loser like me... imagining it twist when he learns sis's secret... I know it's pathetic, gloomy desire, but unbearably thrilling.
English direct lecture ends, self-study time, back to my seat—but excitement won't subside. Eyes fixed on textbook, looks like intense studying to anyone, but actually, not turned a page, lost in fantasies.
Fantasies. My escape since kid days, bullied, no friends. Outlet from stuffy, boring, stress-filled reality.
-Gaining superpowers, killing bully bastards.
-Wizard, hypnotizing class bully girl Choi Ye-na, raping her.
-Paying protection to Jo Yong-ho, actually becoming friends...
-Chaebol, building a harem.
In fantasies, I become Hulk, dragon, bully, chaebol. Can do anything. And... what I craved most was sex. Not weird—pubescent boy's raging hormones, who doesn't know? Plus, yeah, ugly monkey like sis calls me. What girl chats nicely with an ape? Love with women... sex... eternally impossible for me.
So only indirect via porn, erotic stories, hentai... piling up fantasy castle from those.
And... fantasies impossible in reality got hardcore.
Today: shoving lightbulb in Choi Ye-na's pussy after she stole my money. Forcing piss, licking floor. Choking to forced orgasm. Punching belly. Impregnating, then incest with the kid.
In my fantasies, omnipotent god doing all. Knowing impossible in reality, twisted castle grew unchecked.
But now... no.
Sis... fuck... wanna fuck again. Hurry home, fuck her more!
Real, actually fucked sis. And today, tomorrow. Keep fucking. First time, twisted fantasy realizable. In reality, with real woman... cousin sis no less...! Not porn or hentai, not silicone onahole—real woman's flesh pussy, thrusting, cumming. Real conquest, humiliation of living woman. That pleasure I never knew... now at home, academy too.
So even looking at book, fantasizing: how to fuck Yeon-woo sis at home, what positions. What 'mission' for humiliation. Suck dick or balls? What clothes for max shame. Let next-room Jin-woo hear sis-getting-fucked sounds.
Those unspeakable gloomy fantasies, time flies immersed. Dick stays hard, lower belly aches, but soaring dopamine from now-possible fantasies, trance state ignoring pain.
Lost in fantasies near blackout, kind cousin Jin-woo taps shoulder, pulls me back.
"Hey. Time's up. Let's go."
"Huh? Already?"
Fresh play, axe rots unnoticed—exactly that.
"What's with you today?"
"Huh? What?"
"Seemed spaced out somewhere else."
"Oh. Haha... nothing. Let's go home."
Unlike usual, heading home feels unbearably exciting.
