Because She's My Little Sister – Thrusting Deep Again Without Pulling Out
Because she was my little sister, I thrust my cock—which I hadn't pulled out even after cumming—deep back inside her pussy. It was so sensitive from the way I'd pounded her earlier that it would've stung if there'd been even a little less slickness, so I moved as slowly as I could. Her inner walls, now stained with my cum, were even slipperier than before, offering no resistance at all. Pinning her down from above so she couldn't move, I pressed my pubic bone against hers and made just the tip of my glans twitch.
I wasn't pistoning in and out, so she didn't moan, but every time my cock throbbed, her walls responded in kind, and it was so damn cute I almost laughed.
"...You said you weren't gonna."
"Liar."
"I said it was natural. Never said I wouldn't."
"It's natural to feel lust for your little sister?"
"Yeah."
"...Dog pervert. Fucking trash. You're my real brother. Feeling that way about your little sister. You're insane."
My little sister verbally tore into me, cursing me out, then gazed at me with a blissed-out look before pulling my neck down for a light kiss on the lips. After only ever hearing "I love it" from her, overlapping our bodies while she called me trash felt way more stimulating than usual.
"Pfh... haah... fuu... you're such fucking trash..."
"Why do you like kissing so much?"
"...Wanna know?"
"Yeah."
"You gonna take responsibility if I tell you?"
"I'll take responsibility even if you don't."
"...W-Well, then I guess I have no choice."
"What is it?"
"Wait... just a sec. Lemme prepare myself."
She cleared her throat with a little ahem, as if she were about to drop some earth-shattering revelation. Then, carefully picking her words one by one, she told me.
"Even with my eyes closed... I can feel you, Oppa."
She brushed her lips lightly against mine. Then she pulled back a bit, opened her eyes, and looked at me. Her face had completely melted at my promise to take responsibility, so adorably.
"Kissing... until it feels like I can't breathe."
She closed her eyes again and this time tangled her tongue with mine, like she was demonstrating. The moment our oral membranes touched, the connected ones down below twitched too, as if saying it felt good. We devoured each other's lips and tongues without even breathing until we were desperate for air, finally breaking apart to gasp it in. Saliva stretched between our mouths before snapping with a plink—a sight I'd seen countless times, but still so fucking hot.
"When we pull apart and I open my eyes... I love how you breathe all rough, staring at me with those eyes."
"...Why? You just called me trash."
"But if you weren't trash, you wouldn't do this to your little sister."
"...True."
"So... I like that you're trash, Oppa."
Even though I was just keeping still inside her so obediently, she was driving me crazy, making it impossible to stop. I was already totally hooked. Every little gesture of hers turned me on, every word she uttered threatened to burst my heart. It went way beyond simple lust. The twisted possessiveness I'd vaguely realized long ago was finally being satisfied, sending thrills through me.
"Hey, Kim Gyeo-ul."
"..."
"Gyeo-ul-ah."
"...What, Oppa?"
"You like being pinned down by me that much?"
"You pinned me down all on your own."
"...Yeah. My fault. But you didn't say no."
"'Cause I'm your little sister? I have to take it when Oppa pins me down."
"So why do you keep begging me to fuck you senseless?"
"...I felt wronged."
"Wronged how?"
"It's unfair if only I like you. If you just like me out of nowhere without me doing anything... it feels a little less."
"...Less what?"
"Less like I'm sinning. 'Cause it's your fault, not mine."
"I feel like I'm sinning so bad because of you that I'm going insane."
"But you're trash, right? Doesn't it turn you on more? 'Cause you're such a dog pervert."
"Then what does that make you, wearing panties like this to seduce trash like me?"
"...I'm your real little sister, haaah... ah, hek... haaah..."
I hated shit like that. Relationships just for pleasure, affection based on looks—fuck all of it. What I liked was twisted bonds, grotesquely so. In books or movies, I always gravitated toward those kinds of relationships. Ones that could never be broken, unrealistic as hell.
"...Haa, Oppa. It... feels like you're super hard again..."
"You think I'd stop after just once?"
"You're such... a dog pervert. I heard guys get tired after one cum."
"Where'd you hear that crap?"
"Internet... or friends of friends... haaah..."
"They're the weird ones. I'm normal."
"Haaah, you're just the one with too much sex drive... getting horny for your little sister."
"I used to be fine before."
"But every time, you go four or five rounds. You're not a beast..."
"...You're the one who keeps driving me crazy. I used to know restraint."
I had my lines, my own morals. Not super moral, but I wasn't some deviant outside the norms. I was the type who could hold back today for tomorrow. But thanks to you, I stopped giving a shit about tomorrow. Today was happier than yesterday or tomorrow.
"Liar... fucking trash who pins down his real little sister... restraint my ass."
"...Want me to pound you like before?"
"Nooo... that really hurt..."
"Can't hold back anymore. What am I supposed to do?"
"Your sex drive is insane... having a dog pervert like you for a real brother..."
"What about it?"
"No one else would take it... ah, haaah... agh... it hurts..."
She'd been panting like that nonstop, yet still had the stamina to provoke me endlessly. I wanted to punish her for it. I ground my pubic bone harder against hers, teasing the back of her cervix, and she actually cried out in real pain. I froze, a bit scared, but honestly, my anger hadn't fully faded. It wouldn't until I'd dirtied her insides again—no, over and over. Now that she'd made me like this, I wanted it all.
"Oppa... can't you go easy, just a little...?"
"Why should I care about you? You said do whatever I want."
"When did I..."
"Don't you remember saying you'd give me one kid?"
"Th-That was... 'cause you said... you'd take responsibility..."
"One won't be enough to satisfy me. What're you gonna do? Huh?"
"Still... two... is too much..."
"Why?"
"One... I can lie and say Dad doesn't know... but two... it'll get found out..."
"...What?"
"No choice... Mom would freak if she knew..."
Up until then, I'd thought her saying she hadn't taken her pills was a joke or some bullshit she'd picked up to feed my fetish. But hearing her gasp it out like that hit me with a wave of reality. What if she really hadn't? And I'd dumped so much inside? It'd be weirder if she didn't get pregnant. Was the pharmacy open? Is Christmas Eve a holiday? Do ERs give morning-after pills? What if she really is? But we're blood-related. What about the family registry? A barrage of trash thoughts and real worries raced through my brain, but in the end, only one remained.
She's mine. I won't let it be any other way.
"Fuck, I said I'd take responsibility."
"Haaah... hek...?"
"Shut up with that shit. It's my responsibility. My kid."
"Hek, haaah... for real... really?"
"You think I'm lying? Out of my fucking mind with lust?"
"Rea... haaah... you'll... take... responsibility...?"
"I will. For life. Whatever beatings we take, fuck, I'll handle it all. We'll run overseas or wherever—I'll be the dad, and you're my little sister."
"Rea... lly...?"
"I promise."
Swept up in a sudden whirlwind of emotions, I crushed her beneath me. I thrust in at an angle where my cum might overflow but not spill out, and as she stared at me with that dumb, blissed-out face—like her IQ had dropped by half—I sealed her mouth with mine on purpose and hugged her tight.
"Hmph... puha... Oppa..."
I devoured her lips until she couldn't breathe. The moment we parted, she sought me out again, saw my pissed-off face, and gently stroked my hair before pulling me into a tight embrace.
"I love you... Oppa..."
Her voice dripped with happiness as she confessed, urging me to cum. Unable to hold back the surge of feelings, I did it again—one more time, for real this time—flooding her pussy deep inside.
"Haa... haaah... fuu..."
"Hoo..."
"...I did it. Making a baby... with Oppa."
"...Kim Gyeo-ul. Gyeo-ul-ah."
"Yeah... Oppa."
"I love you... so much."
Overlapping with my little sister always makes me stupid. Too much dopamine, blood pressure and body temp through the roof—no room for normal thoughts. But with you in my arms, none of that mattered.
"...Why?"
"Uh... 'cause you like me too much?"
"Why do you think I like you that much...?"
"You said it's 'cause I'm your real big brother. Didn't think you'd remember."
"Then... why do you love me?"
Same position as before, same level of pleasure-drenched stimulation, but one tiny thing was different. No more hesitation.
"Because you're my little sister."
"...Just any little sister?"
"My real little sister. ...I love you."
"I've wanted to hear that... forever."
I'd just thrown her own words back at her, but she made a face like she might cry, then clung to me and hugged me so tight I couldn't breathe.
"...From the moment I started liking you, Oppa. All along."
"I'll say it every time you want."
"No, once is enough. ...I love you, Oppa."
"...I love you, little sister."
Exchanging words no one else could ever hear, just for us, we stayed like that as siblings for a good long while. I didn't want to think at all. Family was warm, cozy, and comfortable. Right there.
