The Story of Watching a Movie with My Brother

"Haa... I'm so tired..."

The short but somehow endless trip to Busan was finally over. I'd even slept on the KTX, so why was I still this exhausted? Maybe I really had gone too hard yesterday...? Though it didn't quite feel like that was the reason.

'Better change out of these clothes first~'

The underwear I'd worn since yesterday. My bra was soaked with sweat, and in a moment of irritation I'd considered going braless, but if I did that I knew I wouldn't be able to control myself. The way my nipples rubbed against fabric felt far too good.

"......"

I'd almost skipped it, but in the end I put the bra on anyway. Obviously it was to prevent sagging. It had nothing to do with being conscious of anyone. No matter that he was my younger brother... it would still be embarrassing if he saw. He might think I was a vulgar woman.

When would I finally be able to show him without shame?

"The dark laundry today, so put it in the machine."

"Okay~"

It was perfect timing since I'd wanted to wash them anyway. I should toss the unwashed shirts in too~

"Ugh..."

"......"

Jiyun emerged from his room, stretching. Ah. His six-pack was on full display. Why was he showing that to me? What was I supposed to do...!

"......"

Worried I'd end up staring at Jiyun again, I quickly loaded the laundry and came back out. Had I shown him my underwear earlier? I couldn't remember. What if he had seen? Uuu....

"...Mom!"

Jiyun brushed past me. That male scent. He'd probably never recognize it in his life, but to me it was unmistakable. Mixed with the pleasant fabric softener, it made me want to bury my face in it. Wait, was that flash I just saw his underwear?

"Yeah? What is it?"

"Want to go see a movie together later, all three of us?!"

"A movie? Anything good playing?"

"Plenty. It's Liberation Day, so there are independent films too."

I suggested the movie both to distract myself and because I felt guilty about leaving Mom alone yesterday. It had been a long time since our whole family had a proper day off. Chatting with Mom always melted my stress away.

"......"

"Going to sleep?"

"Yeah. I'm tired."

"Alright. Sleep well~"

"Yeah. Good night."

Jiyun disappeared into his room. He'd probably stay in there sleeping for a while. But what if he was doing it alone in there? If I saw that, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I didn't think I'd be able to hold myself back... Yeah, better not go in.

"Did you have fun ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠yesterday?"

"Yeah. It was fun."

"What was that about all of a sudden? Going all the way to Busan."

"It's nothing... I just had something annoying happen."

The gallery I managed these days was a complete mess. The story about the panty-stealing younger brother had suddenly spread everywhere, and people were flooding in on a pilgrimage. I'd created the gallery just so I could giggle to myself, but now it was contaminated with impurities.

'Maybe I should just nuke the whole thing...'

But then I'd lose my collection. This was the only place where I could release these dirty, shameful desires of mine. I couldn't lose the one spot where I could openly say I wanted to fuck my brother every day.

"You should've contacted me beforehand. I would've given you money for the trip."

"No way. We're old enough to take care of ourselves now, you know?"

"In my eyes, you two are still children."

"I give you allowance every month~"

"And I'm putting it to good use, thanks to you."

Mom's scarves, clothes, and the bags she carried were all bought with the allowance I gave her. As expected, expensive clothes really brought out Mom's elegance. At least she wouldn't get criticized for looking shabby wherever she went.

"What are you watching, Mom?"

"That recent drama. The one with the chef."

"Oh, that one~ Did you know it has an original story?"

"What original?"

"It's based on a web novel. They changed the title from the original."

"Really? I had no idea."

It was a drama I'd enjoyed too. Unlike the disastrous ending of that story about the youngest son of some family, this one had been genuinely entertaining.

"But why watch on your phone instead of the TV? We have OTT."

"I don't know how to use it. I only know how to change channels."

"Want me to set it up for you?"

"No. I'll just watch it like this."

She couldn't handle the smart TV but somehow managed the smartphone just fine. She always nagged me about getting a turtle neck, too.

"Going to sleep?"

"Yeah. No plans to go out, right?"

"Kyung-soon wants to meet up."

"Aunt Kyung-soon? Okay. Don't come back too late."

"Got it."

I went into my room and dove straight onto the bed I'd been about to lie on earlier. Nothing beat that soft, fluffy feeling. It would be nice if the KTX offered first-class seats. Maybe our country was just too small for them.

I really wondered what sex felt like. I wanted to try it.

I tore open one of the condoms I'd brought back yesterday and slipped it over my finger. Maybe this way I could at least get a sense of the feeling. But I hadn't felt much yesterday, so would today be any different...?

"...Haa."

When I came back to my senses, my hand was already slipping inside my pants. Had I not learned anything from yesterday? Or had rubbing against the real thing raised my dopamine baseline?

'Mom's right outside...'

My finger pushed inside. The moment I imagined what had happened last night, I couldn't stop.

'I'm already so wet...'

Maybe because I'd held back with reason until just now, the moment that reason vanished the floodgates opened completely. Did men like women who got this wet? Would Jiyun like it?

"Mmm..."

I slipped my hand under my t-shirt. The bra had been pointless. I unhooked it, tossed it aside, and fully savored the sensation of fabric rubbing against my skin.

'What do I do, this feels too good...!'

They said too much friction could cause darkening, but I couldn't stop. It felt way too good.

'How did it go, I wonder...'

The person who wrote this post was truly wicked. They only described the part where they showed each other and completely omitted everything after. How was I supposed to know exactly what happened? I was dying of curiosity.

'Should I try it myself...?'

Everything had started with stealing panties. So if I stole some, maybe something would happen. Come to think of it, when I'd put the laundry in earlier, his underwear had been mixed in there.

"......"

I quietly opened my door. Mom must have gone to her room; the drama was playing loudly from somewhere out of sight. Jiyun's door was firmly shut.

'Can I really do this...?'

With desperate resolve, I made it to the washing machine. It hadn't started yet. Good.

'Hoo.'

Like some kind of secret agent, adrenaline surged through me and my body grew strangely calm. I quickly opened the machine and rummaged through it like I was hunting for treasure.

'Found it.'

I swiftly completed my mission, kept my expression neutral, and returned to my room. The moment I closed the door, the corners of my mouth lifted on their own.

Navy ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠blue trunks. Still carrying a faint trace of body heat.

"Sluuurp!"

I immediately buried my face in them.

'What is this smell...'

It was completely different from the faint whiff I'd caught when his erection had pressed against me on the subway. This was a hundred times more concentrated, a thick, heavy scent. They said pheromones were actually odorless, but that had to be a lie. The more I smelled it, the more my reason disappeared.

"Mmm...!"

I tried my best to hold back any sounds. Using Jiyun's underwear as a soundproofing panel, I muffled myself.

'Nooo...'

It felt like the scent was devouring me. No, it already was. The important thing now was sound. From this point on, nothing but the wet squelching should be heard.

"Ah, aah..."

Though thinner than Jiyun's, two fingers now thrust inside me. Imagining Jiyun on top of me made it even hotter. I wished someone would pin me down. I wished that someone was Jiyun. But it still wasn't quite enough.

"Oh, uhh..."

Jiyun's scent and mine mixed together, creating a swamp of madness. I had fallen right into the middle of it.

"Hngh...!"

A shudder ran through my entire body as my toes curled. My hips trembled up and down. It had been a long time since I'd come like this without a vibrator, since that very first time I'd done it alone.

"Haa... haa..."

Oh no. I'd forgotten to lay down a towel. Why was my room such a mess again? I didn't remember taking everything off, so why was I completely naked?

"......"

Looking at my pitiful room and the state of my lower half, I felt more than a little disappointed in myself. Uuu. Why did I keep doing this? Was it because of how his thing had pressed against my ass yesterday? I'd used it well, so I needed to return it to its original place right awa──

"Ah."

I ran straight into Jiyun. What do I do, what do I do? I'd hidden it behind my back for now. He couldn't have noticed, right?

"You weren't sleeping...?"

Jiyun asked me.

"Huh? Yeah... I slept earlier, so there's no way I could fall asleep again."

"True..."

Why was he staring at me so intently? Had he noticed I wasn't wearing a bra? Or had he seen the underwear?

"What about you, Jiyun?"

"I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠just came out to use the bathroom... You can go in, Sis."

"Really? Perfect. I was about to go myself."

"......"

"......"

Why wasn't he moving? I needed to get in and destroy the evidence. If he kept standing there, I was going to get caught...!

"What about Mom?"

"Looks like she's sleeping too. Oh right! Let's go see that movie later."

"Ah. Yeah. Anything you want to watch?"

"Anything but a kids' animation."

"Obviously~"

Hurry up and move! Why was he coming this way!

"...Why are you hovering there?"

"It's nothing... just..."

I couldn't hold back anymore and spoke. What if he got suspicious...?

"Can you move...? I need to go in."

"...Yeah."

Oh no, did I just sound angry? No, I thought I'd spoken gently. He wouldn't misunderstand, right...?

"Sis."

"Yes?!"

The moment Jiyun stepped aside and I tried to go in, he called out to me.

"Does your back hurt?"

"Why would my back hurt?"

"You were standing with your hands behind you..."

"......Ah, yeah! It hurts a little."

"Is it because you slept sitting up?"

"Probably."

He'd thought I was in pain. Thanks to that, I'd gotten away. Even in this situation, he was worrying about me. What was I supposed to do with how cute my little brother was?

"......"

"......"

But why wasn't he going in? Please go inside already....

"...Can I go pee now...?"

"Ah... yeah."

Jiyun finally went into the bathroom. I opened the washing machine and quickly tossed the underwear back in.

"Phew..."

How well had I used it that the musky scent had doubled? That was seriously close.

'I need to wash up first...'

Next time I'd have to be even more careful not to get caught. Ah, I'm wet again.
