Chapter Index

    .

    After the creampie.

    The first thing I noticed was Lee Hayoon making a strange expression, likely due to the sound of my younger sister’s moans ringing in her ears.

    …And then, well.

    After coming face-to-face with my sister’s semen-covered, still-hard cock resting plop on her ass.

    Hayoon just sat there, dazed, for about five seconds.

    “I-inside… inside…”

    Even as her older sister struggled to pull herself out of her embrace, Lee Jiyoon was still twitching in the throes of orgasm, her backside clenching.

    Letting out a satisfied sigh, I followed Hayoon’s gaze downward—toward Jiyoon’s ass, where a torn condom, smeared with cum, was barely hanging on.

    Of course, the cock that had destroyed that condom was still standing at full attention.

    I hadn’t expected to make this much of a mess, given how much I’d already cum today.

    Guess my body’s been working overtime.

    At this point, I wouldn’t be surprised if this little shit had some internal damage.

    Then again, after fucking both sisters senseless and cumming enough to make my head spin, I’m not exactly in peak condition either.

    Sweat’s pouring off me like rain.

    And my throat’s fucking parched.

    “Wh-what do we do? Jiyoon, what if she’s… pregnant…?”

    “…Unnie, I’m… safe…”

    “Safe…?”

    “…Yeah…”

    “Safe…? When was your last period…?”

    Hayoon, now right beside me, wore the gravest expression in the world as she stared at the cum still leaking out. Meanwhile, Jiyoon, collapsed face-first into the couch, barely managed to croak out that she was in a safe window.

    A moment later, Hayoon bit her lip, mentally retracing the dates before finally letting out a sigh of relief.

    Judging by her reaction, Jiyoon hadn’t been lying when she told me she wasn’t in a risky period.

    I’d sometimes imagined—what if, out of nowhere, Jiyoon grinned and told me I was gonna be a dad?

    Thank god that’s not happening.

    I’d rather save that for when these two’s reputations are sky-high.

    It’s still too early to leave my mark on them like this.

    I want to claim them completely—when the urge to conquer is at its peak.

    Or something like that, anyway.

    “Haa… At least it wasn’t a dangerous day…”

    Hayoon sighed like the weight of the world was on her shoulders before glancing up at me.

    That usual cute expression of hers was gone, replaced by something firmer—more like an older sister’s.

    “Seo Woojin.”

    “…Yeah.”

    “If the condom broke, you should’ve pulled out.”

    “…S-sorry. I guess I was too into it to notice.”

    “We almost had to go to the hospital… Haa…”

    I did know.

    I just didn’t care.

    But I played along, putting on an apologetic face, and Hayoon didn’t press further.

    She just glanced at Jiyoon’s cum-drenched pussy, let out a tiny “eep!”, and turned away, her face burning red.

    …This part’s a bit disappointing.

    Instead of sneaking glances at her sister’s freshly creampied cunt, she just looked away immediately.

    I was hoping for a more… interesting reaction.

    Not the worst, sure, but still pretty tame.

    She wasn’t strictly against creampies, but her reaction made it clear she didn’t take it lightly either.

    I swallowed a sigh.

    At first, I’d planned to use Jiyoon—either to assert dominance or to provoke jealousy—to get permission for my first creampie.

    But seeing Hayoon’s virgin-like reaction, I might need to rethink my approach.

    No solid ideas yet, though.

    But I’ll figure something out.

    “Jiyoon-ah. Lee Jiyoon.”

    “…Mmm.”

    While peeling off the now-useless condom, Hayoon crouched down to eye level with Jiyoon—as if their earlier bickering never happened—and lightly shook her sister’s shoulder.

    The movement made more cum glug-glug out of Jiyoon’s pussy, staining the couch, but Hayoon just silently grabbed tissues from the coffee table and wiped it up.

    I kept my mouth shut for several reasons.

    One of them was—

    This.

    “Feeling better now? You were moaning like crazy earlier.”

    “…I’m fine. It just… felt good…”

    “…Sex did?”

    “Y-yeah… But also…”

    “…”

    “The creampie… especially… felt really good…”

    Jiyoon.

    “Oh, and I think… I got way more cum than you did…”

    “…What?”

    “The time was about the same, so… doesn’t that mean I won, unnie?”

    “…”

    “…What’s wrong? Woojin’s body likes me more than yours. …Heh.”

    Jiyoon, still riding the high of her first creampie right in front of her sister,

    kept poking the bear.

    Which is exactly why I decided to stay quiet.

    198

    …Ugh. Fuck.

    Unnie’s flick hurts.

    Woojin’s all bark and no bite—it never actually hurt.

    But why’s unnie hitting me for real…? Ugh…

    It’s not like Woojin’s gonna go back to her just because of this.

    If she’s mad that he likes my body more, too bad.

    Should’ve been born more his type.

    Tch…

    “…Unnie. I have a question.”

    “If you’re gonna spout more nonsense about being ‘better suited’ for him, this won’t end with just a flick.”

    “No, no. Not that.”

    “…Then what?”

    “Since you already creampied me… can’t we just keep having sex?”

    “…You’ve got cum inside you. How can you even say that?”

    “Why not? It’s not a risky day.”

    “No. If anything, we should clean it out first. And Woojin needs to rest too…”

    “Eek…!”

    Splash—

    The bathroom echoed with noise despite our hushed voices.

    Water from the showerhead in unnie’s hand sprayed straight into my eyes.

    I flailed, trying to signal her to stop, but she ignored me, diligently dousing my face and body.

    Only after thoroughly soaking me—and the towel wrapped around me—did the water finally stop.

    “Pfft…! You told me to clean the cum out fast, so why’d you spray me…?!”

    “Just because.”

    “You did it on purpose, didn’t you? To piss me off?”

    “Maybe a little?”

    “Ugh…”

    Sure, I messed up, but isn’t she being extra petty today?

    For a second, I almost missed the unnie from her short-lived rebellious phase.

    “…”

    Watching her rinse her right shoulder, I flushed slightly, remembering what had happened earlier.

    I mean.

    I was the one who bit her.

    And I was the one who licked her.

    …So, logically, I should’ve been scolded for it.

    But now that I think about it, she hasn’t mentioned the shoulder thing at all.

    “…Sh-showerhead. Give it to me when you’re done.”

    “…Okay.”

    Is unnie into this?

    I quickly dismissed the thought—I know her porn preferences well enough.

    But aside from that disgusting kink, I couldn’t think of any other reason.

    The most plausible explanation?

    She’s too embarrassed to even bring it up, so she’s pretending it never happened.

    Which, sure, I get.

    Even if it were just two girls, it’d be gross—but we’re sisters.

    “…”

    But back then—

    Woojin.

    Hate to admit it, but.

    His dick was definitely…

    …rock hard.

    “…Why are you just standing there?”

    “Oh, uh…”

    When unnie, pinned beneath me, said “Don’t bite,”

    And when she outright told me “Don’t lick,”

    The way his hips pistoned.

    The thickness of his cock…

    The slap-slap of his lower stomach against my ass.

    Compared to when I cheated on unnie in secret.

    Compared to when I cheated on unnie right in front of her.

    Compared to when I openly cheated and even did lesbian play.

    It was.

    Way.

    More.

    Intense.

    “…”

    What if.

    If, while using unnie like a bed,

    We could show him—Look how hard we’re working for you.

    Would he.

    Fuck us both.

    All night.

    Nonstop?

    —Splash.

    Should I bring it up…?

    If unnie makes a disgusted face, I can just drop it and change the subject.

    Just once.

    Yeah.

    “…Hey, unnie.”

    “What now?”

    “Earlier, when Woojin and I were… y’know.”

    “…”

    The second I brought it up, unnie’s face twisted like a pouting Pomeranian.

    I glanced down at her, then quickly averted my eyes out of sheer embarrassment.

    “…I bit your shoulder, remember?”

    “…Y-yeah.”

    “It wasn’t because I’m a lesbian, okay? You know that, right?”

    “…I know.”

    “Same with the licking after… Anyway… It’s just…”

    “…I know. You said you like Woojin, so it’s not like you’re into girls. …Is this because of that misunderstanding last time?”

    “That’s… part of it, but… Ugh…”

    What do I do?

    This is so embarrassing—maybe I should just drop it?

    …Actually, I don’t have to bring it up.

    The amount of cum he dumped inside me earlier? Total victory.

    Do I really need to team up with unnie to get Woojin hard again?

    Though, to be fair, it only happened because Woojin saw me doing lesbian play with unnie…

    Ugh, fuck…

    If I say that,

    Hayoon’s gonna think I’m just some horny bitch.

    “…”

    …Wait.

    Doesn’t she already?

    The little sister lusting after her big sister’s boyfriend.

    The little sister who stole all his firsts.

    The little sister who got creampied right in front of her, moaning like a slut.

    At this point, I’m less than livestock.

    Right?

    “Unnie. Just hypothetically, okay?”

    “…Why are you dragging this out?”

    Then.

    Even if unnie does see me as a horny bitch.

    Does it even matter?

    I’m only doing this because I want to see her jealous.

    And if the target of her jealousy is a horny bitch.

    Wouldn’t her reactions.

    Be even better?

    “When I bit and licked you earlier… Did it feel really bad…?”

    “Obviously. Why even ask? …It was disgusting. So much.”

    Unnie’s answer came without hesitation.

    I forced a weak smile—”Yeah, figured. Mm.”—while still avoiding her gaze.

    “So… was it ‘disgusting but bearable’? Or ‘never do that again’ disgusting?”

    “…? Why?”

    “Because… of this…”

    No way in hell am I admitting how turned on I was riding him in front of her.

    Instead, I swiped up some of the cum still trickling down my thigh.

    And showed it to her.

    “…I’ve never seen Woojin’s cum like this before.”

    “…”

    “Unnie, have you?”

    …Just how thick was the load he dumped inside me?

    Does unnie usually get cum like this when they fuck?

    Watching her sneak glances at the cum without answering, I couldn’t help but feel superior.

    “From the moment you told me not to bite, Woojin… was so turned on, wasn’t he?”

    “…”

    “You felt it too, right, unnie?”

    “…I don’t know.”

    “And when you told me not to lick, he started fucking me like an animal.”

    “I d-don’t know…”

    “…He didn’t even notice the condom broke, just kept thrusting… filling me up until my womb was packed… fucking bastard…”

    The way her face was burning red made it obvious she knew exactly what I meant.

    I stepped closer to my sister—who couldn’t lie to save her life.

    She backed up but didn’t leave the bathroom.

    So I.

    Bit down.

    On her shoulder.

    Again.

    “Hey, Lee Jiyoon…! …Ngh…”

    “…Still gross? Like this?”

    “Disgusting—get off…!”

    “…How about this? Hahh…”

    “…?!”

    And then.

    On the faint teeth marks my fingers couldn’t possibly feel.

    I dragged my tongue.

    Lick. Lick.

    …I can handle this much.

    But unnie?

    Probably not.

    “Hey, can you give me a straight answer? It’s not like I’m doing this because I want to.”

    “…I-I hate it…”

    “Hate the licking? Or hate talking about it?”

    “I hate it…! Sisters doing this… it’s weird… Hic…!”

    “…Weird turns you on. Plus, there are tons of guys who pretend to be normal but are total freaks.”

    “It’s gross, okay…? I only let it slide earlier because you looked like you were struggling…”

    “Something like this—just kissing your body—is… easy, right? Relatively.”

    “How is this easy…?!”

    Splash—

    Hiding my voice under the sound of the shower.

    …I skimmed my fingers along my inner thigh.

    The cum stretched, sticky between my fingers.

    I showed it to her again.

    And said—

    “Then, wanna suck Woojin’s cock together while looking at each other, unnie?”

    “…Y-you’re insane…”

    “I don’t want to see your face up close either… but if we did, Woojin would definitely empty his balls completely…”

    “…”

    “…Ah, taking turns sucking sounds kinda gross too. We could split the licking, but if we suck, I’d have to taste your spit.”

    “Sh-shut up. Just clean the cum out already…! And it’s not like I haven’t had Woojin all to myself before—”

    “Oh?”

    I poked the bear.

    Again.

    “The amount, the texture… Seems like Woojin prefers the weird sex we just had over the normal kind with you, unnie…”

    That sex just now.

    I want it again.

    For such a simple reason.

    Even carefully provoking her wasn’t enough.

    So I went all in.

    Like I was picking a fight.
