Because We're Siblings
Because we were siblings, when I grabbed my younger sister's thick thighs and spread them wide to either side, her groin was already almost fully exposed, and I hadn't even touched her underwear yet. Not wanting to waste even the time to take it off, I tugged aside the panties— so tiny they were embarrassing to even call underwear. I'd pierced her depths countless times and savored every inch, but that tightly sealed, innocently pure pussy was still waiting for me. It looked so young, without a single hair, yet the gap with her vulgarly enormous breasts had my cock throbbing at its absolute limit.
"Why the fuck are you wearing panties like this?"
"…"
"To turn me on?"
"…"
"You wanted me to pin you down that badly?"
"…"
"Not gonna answer?"
"…"
I stared for a moment at my sister, who kept her lips stubbornly sealed and just shook her head no, but there was no sign she'd say a word. No time for back-and-forth, so without asking, I spread her outer labia with my right hand. Peering intently into her pussy, slick and wet as if urging me not to hold back, she just stared straight at my face, not covering anything. Silently, I gripped my already slimy cock with my free hand. I rubbed the glans against her folds, smearing precum everywhere. Spreading the tightly clenched labia wide, I pushed my cock into the mucosal warmth.
The vaginal walls I'd missed so much clung even stickier than usual.
"O…ppa…"
"You wouldn't answer before, but now you do?"
"…We're… fucking now, aren't we?"
"You begged me to defile you. You did."
"I told you not to… but you did it anyway, forced it… right?"
As I slowly thrust my cock all the way to her depths, my sister—who hadn't even answered before—finally spoke up. She'd offered no resistance or refusal, yet now she was shoving the blame onto me, provoking me. It pissed me off so much, made me so goddamn furious, that it only turned me on harder.
"You were the one babbling on about how you wanted it like this, and now what?"
"I said… no… ah… it's dangerous… I kept telling you… et…"
"…"
"Oppa… you're the one… who forced it…"
"…"
"It's your fault… right?"
I grabbed her breasts so roughly my fingerprints would bruise them, slamming down without mercy, pounding my cock into her. The more I did, the more she gasped and panted, barely holding back moans, acting like she bore zero blame while blaming me nonstop.
"You fucking perv… my own brother… haat… getting hard for his sister…"
"…Yeah, fuck. I'm a piece of shit. A trash bastard who gets horny for his sister and rams her raw without protection."
"You admit it? Hek? Hah… haak…"
"And what if I do?"
"Heeek… hek… you said you wouldn't… but in the end… haak… you do whatever I say…"
"What?"
"I said… don't… clothes? Heeek… even if we do… you're gonna cum inside…"
"…"
"What if… clothes… hoot… I really get pregnant… what then…?"
"…"
"What're you gonna do… oppa… hik? Heeek? Haak… haang… hoo-eot…"
Curious how far she'd push my anger, I propped myself with one hand and pinched her nipple hard with the other. She writhed with a scream half pain, half pleasure, so I let go for a second, then switched to her clit, rubbing it fast with my thumb. She let out a sharp hiiik, sucking in her breath. Even treated that roughly, she didn't resist me at all.
"O…ppa… that's… et… hiiik? Hoot…"
"Why? Feels good, doesn't it?"
"That's what you say… when you force it… ja… na…"
"I'm forcing you, yeah. So what?"
"You're such a fucking perv… my own brother… trying to… hiiik… knock me up… pinning your sister down… haa… ha… crushing her…"
"…"
"Gonna fill me up… hoot… with your… cum… hoot… and not let me go… so I can't run…"
"…I'll do it. If you want it that bad, I'll give you what you want, fuck."
"For real… you're insane… oppa, you're fucking trash…"
She kept poking at my violence, my aggression, until my switch finally flipped. I scraped the dangerously deep, bumpy wrinkles with my glans, and her pussy chewed on my cock wildly. She clamped her mouth shut, not wanting to moan, but whimpers leaked through her fingers. Pinned under her own brother, her most precious place ravaged mercilessly, yet her eyes stayed locked on mine—no trace of disgust.
"Haa… fuck… Kim Gyeo-ul."
"Hak… oppa… you're fucking trash… horny for your sister… hiiik? Heeek… heeek… trash…"
"…Gonna cum. For real."
"Gonna make a baby… inside…"
"Fuck, I'll take responsibility. That's what you wanted to hear?"
I finally gave my sister—who blamed everything on me—the words she'd been dying to hear. The moment she got them, her eyes went soft, staring at me, her face turning into that of an undeniable female in heat. She wrapped her legs around my waist, arms around my neck, pulling me toward the bed.
"…For real?"
"…I'll take responsibility."
"Heeek… if… that's… hoot… what you want so bad…"
Her breathing ragged, her hips bucking every time I ground my glans against her walls, but her final words as she pulled me close were steady, clear.
"I'll give you one kid… oppa's baby."
After saying what she never should have, she nipped my earlobe lightly. Guilt for our sin mixed with the thrill of it, wrecking my brain. In my half-mad vision, there she was—my sister, face melted in ecstasy, gazing at me desperately.
"Fuck… Kim Gyeo-ul. I love you. Kim Gyeo-ul. Ha… fuck…"
"Too deep… oppa… ah… heeek… it hurts…"
Chanting her name, I slid my arms under her back, crushing her completely beneath me, slamming in with my full weight until her guts might bruise. Her convulsing walls gripped and sucked my cock, pulling me deeper like there was more room. I pounded the spot too dangerous, too deep to pierce—enough to leave scars. Untouched, forbidden territory stimulated, she cried out more in pain than pleasure, suffering. But even then, she never pushed me away.
"It… hurts! For real… it really hurts… no joke…"
"Shut up. …I'll kiss it better."
"…K…kiss… quick…"
No more talking. I sealed her mouth. Shoving my tongue between her teeth, licking every corner, she couldn't even complain about the pain, surrendering completely. Like my saliva was painkiller, her pained moans faded; muffled nasal hums from her plugged mouth turned to her sucking my tongue, curling up, hugging me tight. At the same time, her contracting pussy squeezed my cock to the bursting point, climax surging.
"Heeup… he… oppa…"
"…Gyeo-ul-ah."
"You… hiik? Hak… gonna cum?"
"…"
"I'm not lying…"
"…Doesn't matter."
If she wasn't lying, no doubt it was the dangerous zone—but I unleashed the male joy of breeding right there, flooding her depths with thick, clinging semen. Toying with her my way, thrusting despite her pleas, dumping cum inside—the pleasure was beyond refusal. Brain-melting, drug-like, the peak ecstasy of a male wrapped my whole body.
"Haa… hoo… heup…"
"Hee… heeek… o…ppa…"
"…Yeah."
"…You came?"
"…Yeah."
"Even though I'm your sister… you didn't care… came so much it might make a baby?"
"…Yeah."
"Satisfied… oppa?"
"No."
It felt like the most I'd ever cum in my life, but I wasn't satisfied. I was, but I wasn't. The craving to relive that pleasure never stopped.
"Figured… you never are after one time."
"…"
"Your sex drive is insane… your strength too…"
Even after cumming, my twitching cock kept crushing her, and I felt the semen starting to leak out. It sucked that my fluids were escaping her; I wanted to defile her beyond excuse, mark her more with my scent. I didn't want anyone touching even a hair on her—only I should have the right to taste every part.
"Oppa."
"Yeah."
"I don't have many friends… don't keep in touch much."
"…So?"
"Mom comes home late… no one's around but you and me."
"…"
"Even if you keep doing this… I can't fight back…"
"…"
"Pin me down like before… so I can't move…"
"…"
"Pound so hard… I can barely breathe…"
"…"
"Even if it hurts… you kiss me to shut me up… use my body however…"
"…"
"No protection… on a dangerous day… cum inside again…"
"…"
"Even then… no one for me to tell… it's so scary…"
"…"
"…I'm your blood sister, right? You wouldn't do that…?"
"…Of course not."
Of course not—of course I would. Now, every time I heard "siblings" or "sister," lust surged uncontrollably. I wanted to rape her, pin her, dominate her. Even if caught, I wouldn't care anymore.
