Just Another Year-End Day
A winter day at year-end, no different from any other. The voices of celebrities drifting from the TV. The slightly rowdy yet comfortable air in the living room.
"Don't hog the whole sofa—scoot over or something. Fold your legs."
"No way."
Just like always at this hour, my sister was sprawled out, claiming all three cushions. It pissed me off every time I saw it.
"Oppa, my stomach isn't your pillow."
"Then move."
I leaned my back against the base of the sofa and tilted my head back. The warm, squishy pillow twitched, then slipped away from the back of my head.
"...What the hell."
Instead, a weight settled on my shoulder. Soft, delicate skin brushed my cheek. I could feel her breath near my ear.
"Light skinship."
"You know when Mom's coming back?"
"You started it first. I'm innocent."
How long could we keep getting away with the excuse of being 'close siblings'? Was it still okay since it was just light skinship?
"I'm just using your shoulder instead of a pillow, same as you."
"It creeps me out."
"Liar."
Her hair grazed my neck, sending a slight shiver down my spine. The shampoo scent wasn't unpleasant.
"How about hiding your ears at least?"
My earlobe got a little nibble. It felt like blood was rushing there—hot as hell.
"Cut the joking around."
"You prefer it when it's not a joke?"
Her warm exhale blew into my ear canal. A vague sensation crawled up my back. It wasn't quite ticklish.
"I'm not playing along with your little sibling games."
Her arm tightened around my neck. The soft flesh pressing against my head felt even squishier than her belly. I'd tasted that forbidden fruit countless times before—soft and sweet—so holding back was that much harder.
"Does giving in to temptation make the guilt feel less heavy?"
"Kim Gyeo-ul."
I unwrapped her slender arm and turned my head slightly to the right. Naturally, you closed your eyes too.
"...Is this a joke? Or for real?"
"My bad."
A feather-light peck that barely made a sound. You'd said you liked it when it felt suffocating,
"...That one wasn't a mistake."
but I preferred our tongues touching,
"...You're insane, Oppa."
and seeing how you never actually refused, it seemed we were both on the same page—two peas in a pod.
"You saying that?"
"So you hate it?"
"No."
We were too close to pass as just siblings,
"Does that mean you like it?"
"As much as you like me."
"...Aren't you embarrassed saying stuff like that?"
"Of what?"
Too close to define as lovers,
"What's there to be embarrassed about between siblings?"
yet our bond was undeniably intimate.
Christmas had passed, and the end of the year was creeping closer. What a long year it had been. Back in summer, I never imagined I'd turn into this kind of guy. Obsessed with my sister, showing my possessiveness. That much could happen, I guess. Just a bit twisted. But at some point, I'd started feeling rational attraction, sexual desire. And eventually, I couldn't hold back against her every little provocation—I crossed the line. Stole her first kiss, her first time. From siblings to lovers, then back to suspiciously close siblings.
...I had to take responsibility. It was my judgment, my choice. Even if it was an unrealistic mistake, handling it like some thoughtless kid dreaming it away would lead to disaster. That's why I needed to talk with her. About what came next.
"So you're going for English Lit?"
I shoved my sprawled-out sister's legs aside in the living room sofa. Sat at the edge and propped her feet on my thigh. Even if Mom came back from grocery shopping, this shouldn't raise any flags.
"Yeah. To learn English. ...We might have to go abroad, right? Not just English, but lit will make adapting easier."
"...Makes sense."
"And I'll go to a different uni from you."
"Why?"
"Same school, and we might get caught. ...Hard to explain to others."
...Surprisingly thoughtful. Guess I wasn't the only one agonizing. Of course not—we wouldn't have gone this far without a plan. Studying English, pretending not to be on birth control to toy with me. Though it wrecked my self-control and patience.
"Same uni, and you'd push for moving out together."
"...Moving out?"
"No car anymore, so you'd say let's live near school. And drag me along for sex every day—obvious as hell. How could I go to your school?"
"Come to my school, and you'd do dorms or online classes. No need to move out."
"You'd force it anyway. Seducing your pure little sister. Till it gets boring. Every day."
She grinned at me while spouting nonsense that didn't add up. ...Damn, couldn't take it anymore. From now on, I wouldn't believe a word she said during our naughty times. If it actually happened, I'd just take responsibility. If Mom was out playing instead of shopping, I'd pin her down right then.
"...No getting caught till we both graduate, at least. Preferably never."
"Psh, we won't. As long as you don't pull that last time."
"What'd I do?"
"Kissed in the living room. You're crazy."
"You saying that? You jumped me when Noona visited."
"That was... bedtime, so it was fine. You did it in broad daylight."
"So you want me visiting at bedtime? You said if you felt lonely, I could come to your room."
"...Horny again?"
"Haven't done it since Christmas Eve. Three days holding back already?"
No point hiding it anymore, so I was blunt. ...I did want to live together. Denying the fantasy of exhausting each other till we collapsed would be a lie. Falling asleep together, waking to each other's faces. Doing it again first thing. Teasing her from behind while she made breakfast, then again after eating. Not every day, but once in a while? Yeah. Once we're solid outside, we should travel. Abroad's good. Domestic works too—find somewhere decent.
"Three times a week... I won't kick you out."
"Three's low. Can't it be daily?"
"No. I'd get sick."
"Just once is fine."
"...Don't like that."
She sat up—the one who'd been saying no more lately. Then brought her lips to my ear and whispered softly.
"I like it... like last time. Daily, and you won't do that."
"...Do it like that now?"
"No. Mom could come back anytime."
She giggled, pulling away after teasing me plenty—adorably ridiculous. I knew tonight she'd be a mess anyway. ...Gotta torment her quietly. Or plug her mouth? Fantasies swirled in my head, but her continuing words scattered them.
"...You said you'd take responsibility. So take it—don't let us get caught. I wanna live together later. Abroad or here. Oh, and keep a cat. Or a dog."
"Why a pet?"
"...Can't give you kids, so something instead."
"... ."
"I'd do it if I could... but no. ...Mom'd collapse."
"...She'd faint just hearing this."
...Could we hide it forever? I was rock-solid on continuing the relationship. No one more attractive than her, even after dying and reviving ten times. Living together wouldn't lack spark. She's my blood sister, after all. But on whether we could avoid detection like this? No clear answer. It wouldn't be weird if we got caught any second. Yet holding back was way beyond me.
"Gyeo-ul."
"What, Oppa? Voice dropping suddenly."
"You said no med school."
"Probably?"
"Wanna move out?"
"...See? Knew it. Proves my point."
"You sleep a ton—commuting from here would tire you out."
"That's really why? ...Not 'cause you wanna do me?"
"...Honestly, living together here feels like we'd get caught eventually. You solo or us together—worry about that later."
Her living alone wouldn't be a big deal. Might even be more convenient. Satisfy some fetishes too. Less risk than at home.
"...Still hate being apart from you."
"Then say it's dangerous for a girl alone."
"You look the most dangerous."
"Keep scratching at me like that—what're you planning for tonight?"
"Ah, that dangerous look again. Scream if you pounce."
"...Think you could even scream?"
"Wow... saying that to your sister. Total trash. Pervert dog."
I wanted payback on her as she lay back on the sofa, prodding me with her feet—but Mom came back right then, and I took the hit instead. ...Gotta move out together. Too risky here. Not saying I won't visit at night, though.
