55. Siblings—But It's Become Familiar Before We Knew It.
I mounted you, and you lay beneath me, gazing up with those pleading eyes that always tempted me to cross the line. By this point, there was no turning back anyway. Man and woman. Brother and little sister. The distinction had long since lost all meaning. All that mattered was my desire to be with you.
"Oppa. Really, really no. ...For real."
"Because it's that kind of day?"
"...Yeah."
"What kind of day is that?"
"..."
"Is there a day when we can't do it? Even during your period, I get that."
"That's why! ...It's been two weeks. That's what makes it a no-go. For real. You don't know anything..."
"Why?"
"Because if we just go at it like usual... it's super dangerous. We absolutely can't. For real."
For some reason, this felt like the first time—your refusal even after we'd come this far. It excited me beyond hiding. Every time you voiced your rejection, my cock twitched, and before I knew it, I'd stripped off your pajama pants entirely and tossed them to the floor.
I tried to yank away even the skimpy panties that barely covered your pussy, but you blocked me by covering your breasts and crotch with your hands, so I couldn't get that far.
"Can't even during your period. Can't today because it's dangerous. So when the hell can we?"
"Later, I'll let you do whatever you want... Just not today. Absolutely not."
"What's not allowed?"
"...We can't do it. Sex... with you, Oppa."
"Why?"
"Because... it'll happen."
"..."
"It's super dangerous, us being siblings... blood-related siblings. We can't make that."
"...And us blood-related siblings doing this is okay?"
"That's different! That's... as long as no one finds out. But if it happens, we'll get caught for sure..."
"You begged me to defile you. Said it was good because we're siblings. Good because I'm your real brother."
"That's a whole other thing! ...And that's not dirty. So... anyway, no! Absolutely, absolutely not!"
That wasn't the face of someone who meant "absolutely not," nor the attitude of true refusal. I had no idea how much you really knew, but at this point, even I couldn't pretend ignorance. That was no signal to stop.
"Move your hands. Let me strip you."
"I said nooo..."
You squirmed desperately to block me. Of course, it might all be an act, but either way, the difference in our strength made it pointless. A light grip on your wrists subdued you easily, brushing your hands aside.
I undid the front of your pajama top and slowly spread it open to the sides. Maybe because we'd been hugging for a while? You didn't even resist anymore. Your breasts—hornier than usual, though they were always tempting enough to grope—sagged enticingly to either side.
Ridiculously, you weren't even wearing a bra, your sweat-glistened tits fully exposed in all their bare glory.
"...Are you kidding me?"
"...You defiled them."
"Defiled what?"
"The underwear I wear to bed—you made it unusable by dirtying it. ...All your fault."
"I dirtied one pair, and now you have none?"
"If I wear it, you'll dirty that one too... with your sticky stuff. It doesn't wash out easy."
"..."
"I know you'll grope my tits however you want and cum all over my underwear... Pervert oppa."
Your roundabout way of begging me to defile you was pure provocation, and I was more than willing to oblige. I pinned you down so you couldn't escape and latched onto those luscious fruits with my mouth. One bite into that forbidden fruit was sweet and addictive beyond escape.
"Oppa, nooo, don't suck... hyah."
"You said other stuff was okay."
"But this'll lead to you definitely doing it, Oppaaa."
"Doing what?"
"You won't be satisfied with just my tits... nngh."
I didn't bother stopping your words that kept stoking my lust. I licked, sucked, nipped lightly, even tugged your nipples with my lips to stretch them. I mashed your breasts together with both hands, kneading them like dough over and over, ravaging them greedily—but you never pushed me away. You just let out shallow moans, then verbally scolded me the moment I pulled back.
"...Pervert. Rapist. Dog-pervert. My real brother... groping his little sister's tits however he wants."
"If you don't like it, hit me or scratch me."
"Then you'd hit me back. Pin me down. Make it so I... can't move."
"Why would I?"
"Even if I keep saying no, you ignore it. Pound away... boom boom."
"..."
"...It's a day when it could really happen, and you'll still fill me up... with so much inside."
"Kim Gyeo-ul."
Honestly, up until a moment ago, I'd planned to tease you a bit and stop. I wasn't that crazy—I figured I'd enjoy the mood, then obediently do whatever you asked. Hug if you wanted a hug, wherever you wanted it done, there.
But you weren't even trying to negotiate. What was I supposed to do? Why weren't you saying a word about it?
"Why haven't you said a thing about birth control?"
"..."
"Put on a condom or pull out. Why not even mention it?"
"...But when you go into heat... you won't care what I say."
"When have I ever?"
"You'll ignore me completely. Even if I say put it on, you'll do it halfway and pull out anyway."
"...When have I ever?"
"No matter what I say, you'll crush me down so I can't resist and do it anyway... dog-pervert."
"..."
"You can't satisfy yourself unless you do it that way... You'll go at it over and over."
"..."
It was like a button plastered with a "DO NOT PRESS" sticker. I had no clue why you were tempting me like this, testing me, making me so damn happy. At this point, it was suspicious enough. Were you picking up weird ideas somewhere to satisfy my fetish again?
"...You're lying about the pill, right?"
"No! For real... I didn't take it."
"Liar?"
"For real. I really didn't. It's really the day it could... happen, so we absolutely can't..."
"...What could happen?"
"A... baby... It'll happen..."
...I had no idea anymore. I thought I knew everything, but with that expression and tone, I couldn't tell if you were lying or not.
In the end, the only sure thing was my urge to flip those panties aside and slam my cock into you. I couldn't hold back the desire to conquer you, my cock-teasing little sister, and do you however I wanted. Every time I tried to restrain myself, you shattered my patience.
"Eek, Oppa? Why, why are you undressing?"
"Want me to strip you first?"
"I said no, for real..."
"We could do other stuff, so why assume?"
"...Your eyes look really scary now."
"My eyes are always like this."
"With those eyes, you always do it... Every time, every time. You pounce when you look like that."
Whether your provocations were real or not didn't matter anymore. I wanted to repay you in kind for all the teasing. No matter what you said, I wanted to pin you under me and fuck you till you squealed. Ignore your "absolutely not"s, pour every drop deep inside you without holding back. I knew I shouldn't, but the more you resisted knowing that, the more my brain screamed to commit the sin.
With the last thread of conscience I had left, I asked one final time. ...Though your answer hardly mattered.
"I'm really gonna do whatever I want."
"..."
"Even now, kick me or whatever if you wanna refuse."
"...Then."
"Then what."
"Then you'd force me anyway."
"..."
"You're bigger than me, stronger... way more powerful. You'd grab me and do whatever you want."
"..."
"Your little sister. Blood-related. You don't care. Dangerous day, I said no, but you'd ignore it. Make a... baby anyway."
"..."
"Even if your sister says no. Even if I'm exhausted and can't move, you'd use my body however and thrust till the end... cum inside."
"..."
"...You'd impregnate me. Even though I'm your real sister, blood-related, you'd fill me up... so much inside."
Your mouth—shattering my ordinary values, ethics, and morals right to the breaking point—was so infuriatingly lovable. I wanted to defile you all the more. I stole that bewitching mouth, licked it lightly with my tongue, and it parted instantly. I pried that gap wide so you'd never close it again, drool stringing from my lips as I rose up on my knees to look down at you.
I gave you enough distance that you could flee if you wanted, but you showed no sign of it.
"Say it clearly. ...Did you take the pill or not."
"..."
"...Answer me."
"If I say I did... what then?"
"I'll do whatever I want."
"...If I say I didn't."
"Still whatever I want."
"..."
Your pajamas nearly stripped away, drool dripping from your mouth, you looked up at me with those eyes I'd seen countless times... and slowly shook your head.
I kept my promise too. Sober as could be—no alcohol involved, by my own will—in my room, on my bed, I began devouring my little sister, defiling the word "siblings," the phrase "blood-related siblings."
