Chapter 48: Gonna Suffocate to Death...! I Fucked Her...! I... Fucked My Sister!
“Ugh... ugh... ugh!”
I'm sorry to my right hand that's been my girlfriend substitute all this time, but thrusting into a real woman's pussy was nothing like jerking off. Not at all. Unlike my rough hand, a real woman's insides were slick with her juices. Especially my cousin noona—does she have some super wet constitution? I barely even pumped a few times, and already there was so much love juice sloshing around, making squelch! squelch! sounds as it wrapped my dick in this slippery, lewd sensation.
“Fuck... this is insane... huff... huff...”
And the temperature was different too. Her body heat—actually a bit hotter than normal—enveloped me as I shoved my dick inside. That warmth, mixed with the moist slickness of her juices, sent shivers straight to my groin. And Yeon-woo Lee's pussy was special. No comparison obviously, since it was my first, but her outer lips were plump and cushioned like swollen pillows, thick and meaty. Inside, the walls were densely ridged, brushing against my cock with every thrust, teasing the sensitive nerves on my glans.
It wasn't just her looks that made her the ace OP girl. Her fuckability was on another level—a natural-born masterpiece pussy.
Of course, the pleasure of sex is half physical, half mental. Any stimulation gets habituated, raising your threshold over time, but a first time? It's pure novelty. No prior experience to compare it to, so it's inherently thrilling.
And... not just any first time, but incest. With my own cousin? Breaking that taboo naturally melted my brain with forbidden excitement. And it wasn't just plain incest—the target was someone who'd always looked down on me, even after grabbing her weakness as an OP whore, refusing to submit properly, piling up all my grudges. That haughty, bitchy cousin noona... I was raping her, forcing myself on her like a beast.
Sure, guilt flickered, but conquest overwhelmed it. Especially for a guy like me, riddled with inferiority from years of resentment.
Fuck... I'm fucking this bitch...!
Brain-melting extreme pleasure—right then, Cheol-gyu Lee felt his entire lower body melting, getting sucked into noona's pussy hole in a massive wave of ecstasy and depravity. Too excited, he didn't notice the pillow over her face was crushing her airways dangerously.
“Haa... haa...!”
Like a lust-crazed animal, he just bucked his hips wildly, oblivious to noona's struggling kicks below.
Air... can't breathe...!
Of course, Yeon-woo Lee wasn't enjoying it like Cheol-gyu. She was getting raped, after all. A month as an OP whore had worn away any virginity notions, but rape was a whole different beast. And physically, with hyper-aroused Cheol-gyu pinning her down under a pillow while pounding her, breathing was agony.
Gonna... die...!
His frantic hip-thrusts let only fleeting gasps sneak through the pillow gaps—that was her only air.
“Kuhp... uup!!”
She thrashed, but the short, scrawny Cheol-gyu she'd dismissed as weak was overpowering her now. The strength gap was brutal.
“Hup.... uuup....”
Air... can't breathe. Oxygen starvation and fading consciousness terrified Yeon-woo.
I'm... gonna die like this...!
But weirdly, despite the controlled breathing and terror, her lower body reacted oppositely.
“Hah... fuck... it's... squeezing... huff...”
“....uuup”
Face crushed into the pillow, her pussy clenched harder instead. Born with masochistic tendencies, now in mortal peril, her body kicked into survival instinct. Like death-row inmates ejaculating at the end, or isolated lovers fucking desperately. Human instinct to propagate genes before death unwittingly aroused her senses. Just like that time Uncle loomed, unintentionally deepthroating her under the covers with brutal intensity. She hadn't registered it then, but her body had wired pain to pleasure.
Huuuk... gonna... go insane.
When pain overwhelms, the brain pumps endorphins, tricking it into pleasure. Like how spicy food lifts your mood under stress—pain receptors fire, but endorphins reframe it as enjoyment. Same with spanking asses or tits heightening arousal.
Cheol-gyu wasn't doing it on purpose, but the pillow wasn't quite lethal—yet her brain panicked like it was, mimicking breath control SM play, choking to restrict air.
“Uuup....!”
“Hah... huff... like it? Huh?... Noona's enjoying this too? Yeah? Cumming from your cousin bro raping you?”
So Yeon-woo endured psychological torment of being raped by her ugly, despised cousin bro, physical agony of breath control under the pillow, and her masochism... shudder shudder... climaxing shamefully mid-rape.
Noona's body under him shuddered violently once, then thud! went limp.
“Hah....?”
Even Cheol-gyu's pleasure-numbed brain flashed danger.
“N-Noona?”
Panicking, he yanked the pillow away, revealing her face smeared in tears, snot, drool.
“Hah... haaack...!”
Thank god—not fully suffocated. She gulped huge breaths.
Worried he'd killed her, Cheol-gyu relaxed, but...
“Ah, what... thought you were dead...”
“Haa... haa... haauk...!”
“....?”
Something was off with noona's reaction.
“...Noona?”
“...Hah!... Huff!... Haaack...”
Breaths ragged, choking staccato, body twitching finely, lower belly undulating like waves—bulging out, sinking in, heaving wildly.
What... no way... she actually came?
Zero prior sex experience meant Cheol-gyu had never seen a real orgasm, unlike porn. Baffled at first by the unfamiliarity, realization dawned.
“What...? She really came while getting raped?”
Excitement exploded uncontrollably. If she was such a slutty masochist cumming even mid-rape and suffocation, any lingering guilt vanished.
“Noona... haa... haa...! Noona...!”
Grabbing her soft, pale convulsing body, he pistoned his hips madly.
Squelch! Squelch...! Splurtch! Squelch! Squelch! Squelch!
“Hngt... haa... haa!”
Post-orgasm, her pussy was stickier, slicker; massive juices gushed out with each thrust, soaking the sheets instantly. Wet splat splat sounds echoed on every pound.
Pounding her juicy, sopping pussy like a maniac,
“Haa... aaah... gonna cum...”
Cheol-gyu felt his pelvis melting into weird bliss, eyes rolling back.
“Ah, cumming... cummiiing...”
Too good... how to describe this? Everything before was nothing... this is sex... I wanna impregnate her, fuck my cousin noona raw till she's knocked up!
Chaotic thoughts swirled. Cheol-gyu hit peak ecstasy with his first real creampie inside a woman,
“Ah...? Uh...?”
Just regaining her senses, Yeon-woo felt massive semen erupting deep inside her.
Of course, oblivious in the next room, Jin-woo Lee focused on studying.
“Hydrochloric acid (HCl), sodium hydroxide (NaOH), and potassium hydroxide (KOH). Good, three solutions... mixed in ways (A), (B), (C). Volumes V, 2V, 3V...”
His eyes scanned the table rapidly, combining data. In his mind, ions swirled in virtual beakers, mixing and separating.
“First, variables: HCl molarity x, NaOH y, KOH z. Solution (A) is acidic, so... total ion molarity 8x. That's H+, Cl-, Na+, K+ summed.”
Scribbling furiously, immersed, then—a weird sound flitted by his ear.
-Hngt... haa... haa...
Hm? What was that?
Faint, but definitely odd.
....
Listening briefly, nothing followed.
Hallucination...?
Dismissing it, head back down—then,
-%##!-
Now mumbling from next door, like Cheol-gyu muttering.
Damn punk's noisy... what the hell's he doing?
Polite Jin-woo wouldn't eavesdrop, but the distraction irked his focus.
“Concentrate. Concentrate.”
Suneung loomed. To pass med school, honor Dad, reunite the family— no time to waste.
Neighbor noises bugged him, but noise-cancelling headset fixed it.
“Back to it...”
Had Jin-woo burst in then, he'd have seen unsatisfied Cheol-gyu, post-rape, flopping his drained precious noona doggy-style, mounting her like a stud dog breeding a bitch.
Lucky? Unlucky? Who knows.
