Chapter Index

    .

    And so, the two of them ended up sleeping in after having sex all night long.

    There was no fairytale-like ending to any of this.

    It wasn’t as if tomorrow was the weekend or anything.

    It wasn’t as if he was the kind of man who could stay hard no matter how many times I came.

    If we kept having sex for nearly four hours like today, even I would inevitably hit my limit.

    …And of course, the same probably went for Hayoon, who had taken my cock inside her for those four hours.

    “Haaah….”

    “Hah… Hahhk….”

    I came inside Lee Hayoon, who was too busy gasping for air, as if emptying every last drop from my swollen balls.

    As her body trembled from the aftershocks of her orgasm, her head lolling to the side, I whispered into her ear that I loved her, that I liked her—things like that.

    Then, I showed her the condom, now slack and filled with thick cum, before replacing it with a new one.

    I kept checking on Hayoon’s body, wondering if she might be sore after such a long session.

    And then, once again, I buried myself deep inside her and came hard.

    Not just while holding her tight, but while pounding into her relentlessly.

    Just moments ago, Hayoon had been stammering out I love you and I like you in return—but now, all she could do was grip the bedsheets and let out lewd moans.

    …Lost in the dizzying thrill of conquest, my cock twitched as it spilled nothing but thick ropes of cum.

    “…Can we stay like this for a bit?”

    “…Mmm….”

    For a brief moment, I glanced at the phone lying face-down on the dresser. Then, collapsing onto the bed, I pulled Hayoon into a tight embrace, my body drenched in sweat.

    Her shirt, crumpled in every direction and just as sweat-soaked as mine.

    Breathing in her scent deeply from it, I let my hands roam freely over her body as she squirmed and whined about how ticklish it was.

    …Ah.

    Fuck, what the hell am I supposed to do?

    Hayoon wasn’t even a famous hero to begin with—just Jiyeon’s sidekick.

    Or maybe more like a “key” to get to Jiyeon.

    But the more I looked at her, the cuter she got… Seriously…

    “…Noona. Get on top of me for a sec.”

    “No… You were just making fun of me earlier, saying I was bad at it…”

    “That was a joke… Anyway, I’m not asking to have sex. I just wanna hold you.”

    “Then just lie next to me…”

    “If I lie next to you, I can’t hold you properly. My arm’ll go numb. …Come on. Hurry up.”

    “…Tch…”

    Even our hushed whispers were loud enough to hear at this distance. As I played with her bangs, she finally stopped resisting and gingerly climbed on top of me.

    …Women are human too, so they should normally be self-conscious about things like sweat.

    So why does she have to be this sexy?

    If I had to exaggerate, she even smelled a little like fruit.

    “…Whew. Noona, you’re pretty heavy…”

    “…I’ll get off.”

    “Kidding. Just kidding. If you were really that heavy, my back would’ve given out when you were riding me earlier.”

    “…….”

    “…This feels nice…”

    “…Hey, um.”

    “Yeah?”

    “…Earlier, when I was on top… Did it feel good?”

    “You saw it yourself, didn’t you? What happened inside the condom.”

    “…I-I saw, but…!”

    “…You squeezed me that hard. There’s no way it didn’t feel good, Hayoon-ah.”

    “Mmm…”

    I ran my fingers through her hair—the same hair I’d been tugging and pulling during sex—and Hayoon, her head lowered, began nuzzling her cheek lightly against my chest.

    I’d been planning to save pet play for Han Soo-ah later, but…

    Now that I think about it, Hayoon would suit it pretty well too.

    Even without animal ears, she’s basically a wagging puppy or kitten at this point.

    And if we used adult toys, we could even give her a tail in no time.

    She looks pretty worn out today, though, so maybe I’ll bring it up casually next time.

    …Hey, can I put a collar—

    —around your neck?

    “…Oh, right. Noona.”

    “…?”

    “Shouldn’t you be heading back soon? It’s almost midnight.”

    “…Yeah. I should.”

    “What did you tell Jiyeon? It’s not like you’re late because of work.”

    “Just, well… Told her I had something to do…”

    “…Then she probably already figured it out. Why you’re coming back late, Noona.”

    “Sh-Shut up…”

    I chuckled and pinched her cheek, making her puff it out in protest.

    She acts all mature because she’s a year older, but why does she keep doing these cute things otherwise…?

    Still smiling, I rolled us halfway over, then pushed myself up from the bed while holding her.

    “Wanna shower together? Like earlier?”

    “…J-Just so we’re clear, no sex…!”

    “…Obviously? We’ve never done it in the shower before.”

    “I-I mean, just in case…!”

    “Besides, if we did have sex in the shower, it’d be hard to use a condom, so we’d have to go raw…”

    “…….”

    “…Pervert.”

    “Eek…! N-No…!”

    Her face flushed, Hayoon started pounding my chest with her tiny fists before finally scrambling off the bed like she was running away.

    Not that it mattered—she was just shuffling toward the bathroom in nothing but my shirt.

    Anyway, raw sex…

    It’s fine if she’s on birth control or if it’s a safe day for creampies, but that’s just fine.

    Going at it recklessly anytime isn’t my style.

    Handjobs are hot because blowjobs exist.

    Blowjobs are hot because condom sex exists.

    Condom sex is hot because raw sex exists.

    And creampies are hot because pull-out sex exists.

    If I creampied her all the time just because it’s hot, I’d get bored of it fast.

    Of course, if Lee Jiyeon—who’s usually ice-cold in front of others—blushed to the tips of her ears and stammered out a request for me to knock her up before her sister…

    I’d pump her full of cum all night long until her fertile womb was stuffed to the brim.

    But it’s still too early for that kind of talk.

    As for raw sex with Hayoon…

    Maybe I should save it for when I’m doing all three of us together.

    …And if I only use condoms with Jiyeon,

    I might get to see some interesting reactions.

    “You should take your hair tie out before going in. And your clothes.”

    “I’ll do it myself.”

    Hayoon stomped into the bathroom, clearly sulking.

    I was about to follow her when I paused, turning instead toward the dresser where my phone lay face-down.

    “…….”

    As expected.

    Still connected.

    “…….”

    Listening to the faint sounds of movement from the bathroom, I briefly considered what to do about this.

    Hanging up with a simple I’m ending the call would be one way to handle it.

    Or I could play dumb and ask What are you doing?

    But in the end, the most satisfying option was obvious.

    “…Hmm.”

    Without a word, I ended the call, stretched with a groan, and headed to the bathroom.

    Of course,

    the phone didn’t ring again.

    How long has it been since the last time?

    Coming home after class and not playing a single game.

    And then, just like that,

    listening to Seo Woojin and my unnie’s voices,

    I lost myself in hours of masturbation—

    even pulling out unnie’s towel and soaking it wet.

    How long has it been?

    …The first time?

    No, probably not.

    Not since middle school, when I first learned how to touch myself.

    Not since high school, when I started vaguely realizing my preferences.

    I’ve never masturbated this much before…

    So yeah.

    The first time.

    “Haaah…”

    The soaked towel? Easy. I could just say I spilled a drink, toss it in the laundry, and let it slide.

    But the smell filling my room—

    this reek of a bitch in heat—wasn’t something I could explain away. So I opened the window, airing out the room as much as I could.

    Of course, I could just own up to it—I was jerking off while you were gone, so what?

    But what kind of sisters in Korea would ever have that kind of conversation?

    Honestly,

    sharing the same sex partner between sisters was way more realistic.

    Pffft…

    “…My legs hurt.”

    A late March night.

    The cold air drifting in through the window cooled my flushed cheeks, if only for a moment.

    First, I started putting away the things I’d taken out for my little pleasure session.

    Unnie’s hair tie, which had been holding up my short, pale hair just moments ago.

    Unnie’s dolphin shorts, which fit my hips perfectly and stirred a strange sense of rivalry in me.

    Unnie’s clothes, always carrying her scent.

    …And the clothes Seo Woojin bought for me.

    The ones he complimented me on, saying they suited me—even with unnie right beside me.

    Biting back the urge to start touching myself again, I hung them back up on the rack like nothing had happened.

    No. No way.

    Unnie had gone to shower a while ago, so she’d probably be back soon.

    What would she think if she came home to find me jerking off while hugging the clothes Woojin bought me?

    Unnie’s too nice to cuss me out on the spot, but…

    She’d be so flustered.

    …Hey, that’s my boyfriend—

    She’d probably say something hot like that.

    “Hahh…”

    So this has to stay a secret.

    The “sex practice” excuse I used to meet Woojin behind unnie’s back—all of it has to stay secret.

    Never, ever let unnie find out.

    As I halfheartedly repeated Unnie, I’m really, really sorry in my head,

    my phone—still warm from eavesdropping for so long—vibrated lightly.

    “…”

    Unnie? Or Woojin?

    If it’s unnie, she’d only ever text me to come out and help carry groceries. So probably Woojin.

    If it’s him, what did he send?

    …Was it about how I teased him earlier for being bad in bed?

    Gulp. I swallowed hard before picking up the phone from where I’d left it by the bed.

    [Seo Woojin] – Was it really that bad?

    Luckily, Woojin’s message was just a single, playful line.

    I’d been a little worried that I’d gone too far and pissed him off, but

    seeing that easygoing reply put me at ease.

    Even though he acts all sweet normally, what we’re doing behind unnie’s back is definitely bad.

    That weird dissonance is kind of funny.

    If Woojin were as bad as me,

    he’d probably have fucked me senseless right next to unnie while she was asleep, muffling my moans…

    The fact that I’m the only bad girl here—

    …kinda turns me on.

    Heh.

    [Lee Jiyeon] – Total trash.

    [Seo Woojin] – Which part?

    [Lee Jiyeon] – All of it. – Every. Single. Bit.

    [Seo Woojin] – Noona seemed to like it just fine, though?

    [Lee Jiyeon] – How was she supposed to say no in that position? Think for a second. Ugh…

    With my room mostly cleaned up, I flopped onto the bed and started tapping away at my phone, lightly slapping my foot against the mattress.

    This way, I could set up another “sex practice” session with Woojin later, right?

    Unnie likes it rough, so I should tell him to stop holding back and just pound her like an animal.

    If I don’t, he’ll keep acting all gentle, so I’ll have to practice on my own body first.

    That way, when Woojin pins me down, he’ll fuck me like a beast.

    …Of course, I’ll have to get there before unnie does—

    since she’s the one who actually likes it rough.

    [Seo Woojin] – Then I guess I’ll have to try harder next time. – I thought I was plenty rough already. – Trying to match noona’s tastes is a pain in the ass…

    [Lee Jiyeon] – …Hey. You free tomorrow?

    [Seo Woojin] – Free? – Oh. – Nah. You’d hate having sex with a guy you don’t even like, right…?

    …Huh?

    [Seo Woojin] – Anyway, thanks for today. – Sleep well. Text me if your head hurts. – Next time… I’ll treat you to something nice. Something expensive.

    “…….”

    …Huh?
