Waking Up Next to 'Big Sister'
The next day.
I woke up early to the sound of someone stirring. The bed felt unfamiliar, and when I opened my eyes, I realized I wasn't in my own room.
'Big sister's blanket?'
It seemed I had fallen asleep while giving her a massage. I rubbed my face against the blanket, my voice thick with sleep as I murmured,
"Big sister?"
As I propped myself up, I saw Yang Dahee standing by the sink. She was already preparing breakfast, even though it was still early.
"You're up."
"Mmm... did I sleep here? You should've woken me up."
"I didn't want to. You looked so tired. What, don't tell me you're unhappy about sleeping with your big sister?"
I shook my head vigorously.
Just knowing I was wrapped in her blanket made my heart melt; how could I be unhappy? If anything, I felt like a helpless little kid. To think a guy would fall asleep while massaging his sister—I could roughly guess how that would look to a woman.
'If I showed this side of myself to Lee Yurim, she probably wouldn't be able to handle it.'
I wanted to show my weak side and make her crave me. I couldn't wait to see how she'd react if I played the card that she was the only woman I knew.
But not everyone looked at me so kindly. As I rubbed my bleary eyes, Yang Dami walked out of the bathroom.
"Ugh, what is this."
Yang Dami frowned the moment she saw me.
"Why..."
"Hmph, you idiot."
She huffed and didn't even bother looking at me properly. My younger sister, the one who ignored her own brother. Just yesterday, she’d been texting me with an intensity that bordered on obsessive, but her attitude had flipped overnight.
'Even for siblings, she treats me way too harshly.'
I wondered if she’d go easy on me if I acted a bit more pitiful. Feeling a surge of injustice, I whined,
"Why are you like this to me..."
"You idiot, are you still waking up this late? You're not a toddler."
"Sorry..."
I apologized immediately. It was barely 7:00 AM, and I didn't have the courage to talk back. Her neatly trimmed short hair added to her cold aura, making her feel intimidating.
'She looks like a delinquent when she’s like that.'
Big sister had a cold look too, but she at least smiled at me; my younger sister was just plain prickly. Intimidated by Yang Dami, I tried to throw off the blanket and get up.
"Oh."
My underwear was damp.
'Oh no...'
At twenty-one, the realization that I’d had a wet dream made my face burn. I worried if there had been a smell while I was sleeping next to 'big sister,' or if she’d noticed anything strange.
"Sniff..."
I checked for a scent, careful not to let anyone hear. Thankfully, there was no smell, and a quick check confirmed it wasn't a wet dream after all.
'Then what is it?'
Nothing had changed except for sleeping with my sister. Confused, I looked up to see Yang Dahee and Yang Dami.
'It’s cramped.'
They called it a "large room," but it was just a two-room apartment. With a mature woman like Yang Dahee standing there, the place didn't feel empty at all.
'She’s in her underwear again.'
Yang Dahee was wearing a different pair than the ivory ones from yesterday. She seemed to find wearing anything on top stifling, and her insistence on simple designs really showed her personality. I found myself wondering if even a 'big sister' like her would wear something flashy if she ever got to know a man.
'She’s my sister, but she’s so hot...'
The impure thought forced me to sit back down. I wrapped the blanket around myself to hide my rising erection. Then, pretending I was still half-asleep, I yawned and spoke to Yang Dahee.
"Big sister."
"Yeah?"
"Aren't you going to date anyone?"
If it were Yang Dahee, she could get a boyfriend whenever she wanted. She turned to look at me.
"I'm not interested in that kind of thing."
"...Do you like women?"
"Pfft, what are you saying."
It was a joke between us. Yang Dahee was just too busy with work to bother with dating. I was about to ask if she planned to stay single forever, but I was interrupted.
Yang Dami, who had been glancing at us from the side, chimed in.
"You idiot."
"...?"
Where did I stand in Yang Dami's world? It seemed like no matter what her brother said, she just didn't like it.
'She’s hot, so I’ll let it slide...'
I meant as a woman, not as my sister. Unlike her sister, she was wearing a cotton shirt, but she was bottomless, which kept drawing my eyes. Before I knew it, I was staring at Yang Dami's chest.
'Are her nipples... missing?'
She wasn't wearing a bra, so her breasts were visible through the fabric, but I couldn't see those pointed tips. According to Yang Dajun's memories, Yang Dami had inverted nipples.
"Ah... hehe."
"What, why are you laughing?"
"It's nothing... hehehe."
"You idiot."
Even as she glared at me with a scowl, I couldn't exactly tell her that her hidden nipples were cute. Her breasts weren't very large, just slightly rounded, which made Yang Dami feel a little less intimidating.
'Still, a woman is a woman.'
The body of an adult woman was enough to stimulate 'me.' I had to look away from Yang Dami and wrap the blanket tighter around myself.
While we were bickering, Yang Dahee brought over the breakfast table.
"Dajun, are you cold?"
"A little?"
"Oh my, I'm hot."
She thought I was cold because I was covered in the blanket. Looking at Yang Dahee, the way sweat beads rolled down her forehead—just like she said, she was hot—was incredibly erotic. I’d felt the curves of her body while massaging her yesterday. I wanted to wipe those sweat beads away with my own hands.
"Haa."
Yang Dahee raised her arms to tuck away some stray hairs. Her crimson-colored armpits were glistening with moisture.
'Dahee...'
She was so defenseless despite having such a sexy body. It was troublesome how much I kept seeing her as a woman. Even with her armpits exposed, it didn't feel dirty; if anything, it smelled sweet.
Even though the food was right in front of me, I couldn't take off the blanket.
"You'll spill something, so take off the blanket and eat."
"But I'm cold..."
"You idiot, what a show."
Yang Dami looked at me with disapproval and tried to pull the blanket off.
"H-hey, don't."
"Ugh, you’re so damn stubborn."
I protected the blanket. And I protected my dick. As I held onto the blanket and resisted, Yang Dahee laughed.
"Should I turn on the boiler?"
"That’s a waste of money."
"Even so. If you're cold, we should turn it on."
She had that look on her face she used when dealing with her much younger brother. It felt good to be cared for, but... Yang Dami was making me feel like I was on a rollercoaster.
"You idiot, you're cold because you’re always cooped up inside."
"You were the one who gave me grief for going out yesterday..."
"That’s not the same thing!"
Why is she like this to me? She complains when I stay home, and she complains when I go out. Thankfully, Yang Dahee went to the veranda to check the boiler.
"Seriously, sis, you keep spoiling him."
"I'm sorry..."
"Then just take off the blanket!"
"I'm sorry..."
"Augh!"
A moment later, the boiler started up with a rattling sound.
"Big sister..."
Yang Dahee patted my head. My heart ached with the feelings of 'Yang Dajun,' who loved his 'big sister.' My heart beat in rhythm with the sound of the boiler.
Clatter, clatter...
It was a bit rough.
'Is it going to break?'
It was an old boiler. But it was a familiar sound to us siblings, so none of us paid it any mind. Yang Dami and I waited for Yang Dahee to pick up her spoon first. No matter how hot-tempered Yang Dami was, she still deferred to her eldest sister.
'It’s not like she’s scared of her.'
Looking back at my memories, it wasn't that she feared or avoided Yang Dahee. It was more like she felt a sense of distance, likely because Yang Dahee had a different mother than the two of us.
'Hmm...'
It probably wasn't an important issue. The fact that the three of us—Yang Dahee, Yang Dajun, and Yang Dami—considered ourselves a family wouldn't change. More than that, the women I wanted to focus on were the others.
"Big sister, Yurim is coming over today, too."
"Is that so?"
"Yeah, we decided to study together."
"...I see."
For some reason, Yang Dahee sounded drained when she answered.
'Is it just my imagination?'
I couldn't bring myself to ask what was wrong. Yang Dami, who had been listening quietly, cut in.
"Yurim-unnie has it rough, too."
"Why?"
"Because she has to come over every day to take care of someone like you."
'Wait, what the hell?'
I felt so damn wronged. Lee Yurim was the one who came to see me because she liked me. Just yesterday, I was a guy being pursued by two beauties, Lee Yurim and Chae Riji, yet here I was, being picked on by my younger sister like it was a daily chore.
'She wouldn't actually be saying "I like my brother" deep down, would she?'
I looked at Yang Dami for no reason and just ended up getting cursed at.
"You idiot."
The one who saved me was 'big sister.'
"Still, Dajun is going to school now, too."
"Hmph."
Yang Dami turned her head away. She started eating, stabbing at her rice with her spoon. Yang Dahee was an angel who took care of even her youngest sister.
"Dami, what are you going to do?"
"...Going out to hang out."
She hadn't even finished eating before she put down her spoon and stood up. Then, she really started getting ready to go out.
'Can't you two just get along...'
The time we spent together was too short. If things kept going like this, I worried I wouldn't see them as 'family,' but as 'women' outside the house. 'Yang Dajun' didn't hate his sister, but... I watched her go with a lingering sense of regret.
'Holy crap.'
My younger sister was stripping off her clothes.
'Gulp...'
My heart raced. It was a different feeling from looking at 'big sister's' body. To think that my 'younger sister,' who treated me so harshly, was getting naked right next to me. The feeling that this shouldn't be happening made my lower half tense up.
'She’s... so slim.'
Unlike Yang Dahee, she had a petite chest and a slender, willowy figure. I could even see her ribs slightly. Even if she was smaller than her sister, her proportions gave her a certain vibe, and the fact that such a girl had inverted nipples was strangely cute.
'Ugh, I shouldn't keep looking.'
If I got caught peeking, I’d get an earful, so I lowered my head again. While I pretended to be nonchalant and ate my rice, Yang Dami changed into whatever she felt like.
"Sis, give me some money."
"I gave you some last time, didn't I?"
"Just give me a little more."
"Hmm..."
Yang Dahee scratched her head in thought before pulling some money from her wallet.
"Thanks."
Despite her words, Yang Dami took the money with a prim attitude.
'She’s so chic...'
Judging by her outfit, she dressed exactly according to her personality. Simple, just like her cool impression. She wore a thin padded jacket over a hoodie, but even that looked stylish on her.
'I almost fell for her for a second.'
If she hadn't been my younger sister, she was the kind of woman I’d want to be devoured by. I wondered how a girl with that personality would hold onto me, or how she’d act in bed.
'Ugh, she’s my own sister.'
If it weren't for 'Yang Dajun's' heart, which saw her as a sister, I would have been in danger. We said our goodbyes to Yang Dami, who was just about to head out the front door.
"Have a safe trip..."
"Dami, call if you're going to be late."
"Yeah."
It was a cold, short answer, even for a family member. I thought she was just going to leave, but Yang Dami suddenly turned back.
"Hey, you idiot."
