What Should I Do? I Can't Sleep at All

What should I do? No matter what, sleep just wouldn't come. The mental burden was heavier than I'd expected. After the argument with my sister ended... a strange tension hung between us. No matter how you looked at it, we'd ended up lying together under the same blanket. If I reached out my arm, we'd be close enough to touch, pressed right against each other. A girl who talked back. A fully grown woman. A beautiful woman. A woman I'd kissed. '...A woman I crave.'

"Hey. Why aren't you sleeping?"

It seemed my sister was in the same boat. Ridiculously, the two siblings were both wide awake, staring at the ceiling.

"What about you?"

"I... I'm worried you'll try something weird."

"Keep saying that and it might come true."

"Bullshit. I tell you to drop dead every day and you're still walking around just fine."

"Then I'll become a ghost and follow you around everywhere. I'll watch you shower, and I'll watch you masturbate too."

"You crazy bastard. Yeah, go ahead and die quickly so you can follow me around. Please. I'll even hold a memorial service for you. I'll do a shaman ritual too."

"Aww. You can't do anything without me, but you're still throwing a tantrum."

"You fucking idiot. Does this look like a tantrum to you?"

"If you like it, just say so honestly. Don't be ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠embarrassed."

"It's not that I like it, it's that it fucking sucks. It sucks ass. You. Kang Minjun."

"Alright, alright. No more bad words from now on."

I slowly placed my hand on her head. It was to soothe her temper a bit. There was the same tension I felt when petting a large dog that looked like it had a nasty personality. 'At least if a dog bites you, you can get compensation from the owner.' But with her... should I bill our parents? Your daughter did this to me. If you don't want to raise a criminal child, please send the settlement money quickly. Victim son, perpetrator daughter. What a messed-up household.

With my fingertips, I gently tickled and stroked her hair. Her soft strands flowed between my fingers.

"If you're really having trouble sleeping, want to watch a movie or something?"

"...Is there anything good?"

Oh, she's calmed down. Next time she gets cranky, I'll have to try this again.

"That famous award-winning one that just came out. You haven't seen it either, right?"

"Nope."

"Then let's watch that. People say it's really entertaining."

"Whatever."

"Just wait a sec. Sis, lift your head. Good girl."

"..."

She obediently lifted her head, so I quickly slipped a pillow underneath. See? When she's this well-behaved, how pretty she looks.

"It's definitely cold outside the blanket."

I grabbed the fully charged tablet and lay back down.

"Stay still for a bit."

"I'm cold, that's why. I'm cold."

I subtly pressed myself even closer to her. From her voice alone, I couldn't tell if she was annoyed or if she was willing to let this much slide. When I extended my arm again, she rested her head on it without complaint. It felt like... 'our relationship has gotten a little closer.'

"You don't need popcorn?"

I placed my hand on her head again. The feeling of her hair flowing through my fingers was so nice that I kept touching it.

"It's fine. Just watch."

"Remember how when we watched scary movies back then, you'd always ask to sleep together? You remember that?"

"Back then I didn't know you'd grow up to be this gross."

"I knew you'd grow up to be this pretty, though?"

"...Idiot. Just watch the movie."

She looked like she'd taken a hit. Her reaction was so cute that I leaned in slightly and kissed her forehead. She stayed perfectly well-behaved. As if saying this much was now allowed.

The movie began with the production company's logo filling the screen. Then came the conflict between the characters. The constant tension. I was impressed—it really was a well-made masterpiece. My sister seemed to be enjoying it too. She watched in complete silence, fully focused. The two siblings were enjoying the movie together when—

"..."

"..."

Uh. W-why did it suddenly go there? A scene I never imagined popped up out of nowhere. When I was alone, the level wouldn't have even registered, but right now I was with my sister. And we were pressed tightly together. Feeling awkward, I quickly paused the movie.

"Sh-should I skip ahead?"

Her ears, illuminated by the tablet's glow, were bright red. She probably hadn't expected a scene like this either.

"It's... it's pretty erotic."

"Yeah. Wow, that caught me off guard."

"...Did you know about this?"

"No! Seriously. I had no idea either. I swear on our parents."

"Your mom and dad are my mom and dad too. Who are you to swear on them?"

"Anyway, I'm completely innocent here."

"Really? For real?"

"I literally only knew the title. Nothing else about this movie."

"Then why did you pick this one of all things? It's so dirty."

"You said it was fine. Otherwise I would've put on something else."

"Fine. I'll believe you. It's okay, just keep watching."

"You sure you're okay with it?"

"We're not kids. If it was scary I wouldn't like it, but this isn't that."

In the end, I did as she asked and resumed the movie. Slowly but surely, the man and woman on screen were taking their clothes off. The actress's voluptuous breasts and the actor's firm muscles appeared. They could've at least faded to black. Seriously, both of them. That said, her breasts are really beautiful. Are they about the same size as my sister's? 'No. Please. Down, boy!' Don't imagine it. Please. I tried my hardest to direct my thoughts somewhere far away. I also shifted from lying at an angle facing her to facing forward. If I wasn't careful, I might end up poking her leg with this. Or maybe I already had. Absolutely not. We'd finally gotten the mood nice and we'd been getting along—I didn't want to ruin it and hear her get annoyed again. I didn't want things to get bad between us.

"..."

My sister remained completely silent, still focused on the movie. Was she planning to use this in her novel too? The truth was, those siblings in her story were practically one step away from having sex. That perverted younger brother watches porn with his sister and tells her to do the same things. That crazy guy... he treated his own sister like some kind of toy. Calling her a dog, calling himself her owner. 'If it's your own sister, you should treasure her.' Like I do. Still, I couldn't stop the sweat from filling my palms. I was so nervous I was going crazy. It felt awkward to suggest stopping now. I shifted around, thinking about wiping my hands on the blanket, when—

She jolted violently.

"Sorry. Did I scare you?"

"N-no. Uh. Yeah."

Her dazed reaction. She must have thought I was about to pounce on her in my aroused state. To think she had so little faith in me. That was a bit hurtful. I swear I would never touch her if she didn't want it. I hated the idea of her hating me more than anything. Strangely, a sadistic urge to tease her a little rose up inside me. My lower half had calmed down now, at least. I turned over to face her.

"What? Are you scared I'll eat you up or something?"

I paused the movie and looked at her. She couldn't meet my eyes.

"Yunseo. When someone talks to you, you should look at them."

She reluctantly turned her head toward me. But her gaze was still fixed on my chest. She looked so cute like that that I slowly, very slowly, moved closer to her. I savored every little detail that made her who she was. The hair I'd tousled while stroking it. Her soft cheeks. Her red lips. Her round ears. Her large eyes, even though they were half-lidded. Her signature pale skin was now flushed bright red.

"Don't worry. If you say no, I won't do anything. Your feelings matter most."

I kissed her forehead again, then let her go from my embrace. I guess I'd gotten too caught up in the atmosphere. Feeling a bit embarrassed, I roughly messed up her hair.

"How was that? Did your heart flutter a little? I looked pretty cool, right? Like I wanted to protect you and everything."

"Bullshit."

She swatted my hand away.

"Why? Your heart was racing. Mine's pounding like crazy right now."

"Idiot. If your heart wasn't beating, you'd be dead."

"If you really want to check, go ahead and listen."

I pulled her tightly into my arms. Her soft cheek and ear pressed against my chest.

"You can listen when I stop. Don't act up right now."

"Why? My heart's racing because of you."

"I said you can listen when you stop."

"You said if it stops, that means I'm dead."

"That's why I'm telling you to say something before you die."

"Aww. You liked it too, though."

"Why would I be 'you' to you? That's gross."

"Then can I listen to your heartbeat?"

"W-what?"

"To see if you're really fine or if your heart's pounding like mine."

"Wh-what are you going to do?"

"...Maybe put my hand on your chest and see?"

"Fuck. Just say you want to touch my tits."

"How can you interpret my pure intentions in such a dirty way?"

"Because that's the only way your words sound. This is your chance to cop a feel of your sister's breasts."

"You know, when I really look at you, it seems like you're hornier than ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I am. Is that creative passion for your erotica or something? Does it just pour out of you 24/7?"

"It's better than that pathetic dick of yours. You were poking me with it earlier too."

Ah, shit. She noticed.

"That's why I turned away right away. And let's be accurate with our words. It wasn't poking—it was thrusting. Poking is for needles. Thrusting is for bats."

"Talking more bullshit with that ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠pathetic dick of yours. I should really bring scissors and cut it off. Move! I'm going to sleep now."

She shoved me hard and yanked most of the blanket over to her side.

"Hey. What am I supposed to cover myself with?"

"Be grateful I'm not kicking you out of the house."

"This is my room. My blanket."

"What do you want me to do about it, fucker? Freeze to death for all I care."

This woman. I show her kindness and she repays me with shit.

"Hey! Hey!"

I wrapped both arms around her and flipped her over completely. The siblings were now stacked on top of each other like sushi rolls.

"Let go? You really want to die?"

"You're sleeping like this tonight. I'm not letting go."

I needed to fix this bad habit of hers. She was so small but had such a nasty temper. I rolled her up in the blanket like a mat. It was convenient—just had to lie still and cover her like this.

"It's stuffy. Let go."

She squirmed around inside the blanket until only her head popped out.

"'Let go' is casual speech."

"Please let go, you son of a bitch. Happy now?"

"If you say, 'My beloved younger brother. Could you please let your sister go?' then I'll think about it."

She was about to headbutt me again. I decided to just hold her face tightly so she couldn't thrash around.

"...My beloved younger brother. Could you please ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠let your sister go?"

"My beloved younger brother. Could you please let your sister go?"

"My beloved younger brother. Could you please let your sister go... fuck."

"I didn't ask for the swear word at the end."

Anyway, as requested. I loosened my arms, and she wriggled out of the blanket. Then—

Smack!

She smacked my forehead hard.

"Huh? Where are you going?"

She suddenly tried to get up and leave.

"Sorry, sis. Are you really mad?"

I panicked and quickly sat up.

"No, I was just joking. If you're that upset..."

"Idiot. I'm going to the bathroom. Move."

"Ah. Sorry. Number two? You didn't pee your pants, did you?"

Instead of answering, she flipped me the middle finger. I see. So that's why she was making such a fuss about being let go. She must be dying to go. And I kept not moving out of the way.
