The 'Little Sister' Measuring Size ⋯What Size?
A man and a woman walked out, moving sluggishly.
What appeared before Yang Dami’s eyes were her own brother and his childhood friend, Lee Yurim.
“Oh… Dami, you’re here.”
“Heh, Dami….”
They greeted her, but Yang Dami froze for a moment.
She wrinkled her nose at the suggestive, heavy scent filling the house and glared at the two of them.
'They should’ve aired the place out. Just because it’s winter, they’ve been cooped up in the room all day.'
It seemed fixing the boiler had been a mistake. Thinking that, Yang Dami gave a belated greeting.
“Unnie, you’re still here?”
“Oh… I was studying with Dajun.”
“That’s right. Heh….”
Zap.
Yang Dami glared at Yang Dajun, who was just giggling mindlessly and playing along.
Her ‘brother,’ standing next to Yurim Unnie with a beet-red face, looking around nervously….
As she stared at him, she suddenly noticed something strange.
‘…What is that?’
There was a red mark on her ‘brother’s’ neck.
It looked exactly like a mark left by someone sucking on it hard.
‘Wasn’t the one I bit on the other side?’
Yang Dami tilted her head, her memory hazy.
It hadn’t even been a full day.
It was early this morning, before the day had truly begun.
The boiler had broken, so they decided to sleep together, and she had even thrown her own blanket at her brother when he whined about being cold.
“Huum… Noona….”
“Hehehe, Dajun-ah… Huuum….”
She had been on her way to the bathroom when she found the two siblings tangled together.
‘Geez, you scared me….’
They were curled up in a position that looked like something only lovers would do. Yang Dami thought it was because her sister spoiled him too much.
“Hmph….”
Snorting at the unsightly scene, she approached Yang Dajun.
She wanted to pull him away from her sister.
Yang Dami reached out and pinched his nose.
“Ugh, ugh….”
With his air supply blocked, he should have tossed and turned and changed positions.
But.
“Hmmnya… Huueeum….”
Instead of pulling away from his sister, Yang Dajun just smacked his lips and burrowed deeper into her arms.
A grown boy, rubbing his face against his sister’s breasts without a shred of shame.
‘Geez, you’re not even moving after that?’
Yang Dami ground her teeth and glared at her brother.
Then, she opened her mouth wide.
“Chomp.”
“Augh….”
In a fit of pique, she had bitten his neck.
Yang Dami snorted and turned her head away.
“Hmph.”
She walked past them without even a glance.
Yang Dajun groaned for a while, as if it actually hurt. She tried to head back to her sleeping spot, but as she was about to lie down on the other side, Yang Dami stopped.
“…”
She spun around and changed direction.
She tapped his shoulder and pushed him aside.
She even snatched the blanket and covered herself with it.
“…Hmph.”
The spot Yang Dami lay down in was right next to Yang Dajun.
And now, back to the present.
Yang Dami slowly rolled her eyes, checking the spot where she had left the mark.
“Heh… why do you keep staring?”
“Dami, do you have something to say?”
Yang Dami shook her head and replied.
“No.”
“Then why do you keep looking? Ugh.”
He shuddered and complained.
Yang Dajun, sensing the situation, ran behind Lee Yurim.
“Ugh.”
“Hehehe. Dajun-ah.”
Just like a man, he went to a woman to elicit sympathy.
She didn't know when they had gotten so close, but he was even grabbing her sleeve without hesitation.
‘Geez… I’m a girl too, you know?’
Her ‘brother’ was hidden behind her sister’s large breasts.
‘I have breasts too… oh, geez.’
Yang Dami subconsciously started to raise her hand but stopped herself.
She bit her lip at the sight of Lee Yurim’s body, which was more mature than her own.
‘Hmph, why should I care about something like this? Yang Dajun, you idiot.’
Yang Dami looked up again and glared at her brother.
Her one and only ‘biological brother,’ who had a pretty face but was hopelessly naive….
Yang Dajun’s face was beet red.
‘Why is his face like that again?’
Yang Dami pouted and said.
“Hey, Yang Dajun.”
“What, why.”
Until a moment ago, he had been stammering and looking nervous, but now he only gave a short reply.
He was acting cocky because he trusted Yurim Unnie, who was hiding him.
‘Good grief.’
Even so, the person he’d be seeing for a long time at home wasn’t Lee Yurim, but his own little sister.
Yang Dami let out a dry laugh and shot back in a sharp, ringing voice.
“Why is your face so red? You didn’t do the studying you were supposed to, did you go and exercise or something?”
“W-what…?”
Yang Dajun was visibly flustered.
He had been listening with just his face poking out, but now even his ears had turned red.
He looked around and even started sniffing himself.
‘What is he doing?’
Yang Dajun stammered.
“H-hey, hey, Yang Dami. What are you talking about?”
“No, I’m asking why your face is red. Did you catch a cold or something?”
“Ah… y-yeah. N-no?”
He nodded, then shook his head again.
Yang Dami sighed at his foolish appearance.
“Ha….”
Is he doing that on purpose?
Whether he knows it or not, every word and action of his makes it impossible to take her eyes off him.
It was impressive, just in terms of how much attention he drew.
‘…Because I’m his little sister.’
It definitely wasn’t because she cared as a woman. Yang Dami avoided looking at her ‘biological brother.’
She tried to avoid it, but….
“Ah….”
As she lowered her gaze, she stopped dead.
Her mouth fell open, and only a groan leaked out.
Her ‘biological brother’s’ ‘that place’ was swollen so large it was bulging out….
Yang Dami swallowed hard as she looked at the bulging front of his pants.
‘W-what is that. That thing, when is it going to go down?’
She tried to ignore it, thinking it was just a physiological phenomenon, but it showed no signs of subsiding.
It had already been that big when she returned home.
‘Ha… don’t tell me it was like that even before I got here?’
Yang Dami glared at her brother.
He was standing next to Yurim Unnie without a shred of shame.
Thinking that he had been with her in that state made her own face flush and her body heat up.
‘Hopelessly naive, you idiot.’
It was fortunate that Lee Yurim had been by his side for over a decade. If it had been any other woman, something would have happened long ago.
Yang Dami tried to steady her breathing, glancing at the two of them one by one.
“Dami-ya.”
“Hoo… what.”
Yang Dajun asked with an innocent face.
“By the way, what’s that?”
He pointed with his chin at what she was holding in her hand.
It was the lunchbox she had bought for the three of them to eat, and ‘that thing’ she had bought for only one person.
‘It’s no use showing interest. I’m not giving this to you right now.’
Yang Dami hid one hand behind her back and held out only the lunchbox.
“This? A lunchbox. For you to shove down your throat.”
“Oh….”
Yang Dajun opened his mouth roundly and marveled.
He nodded and even blinked his eyes; he was truly a dim-witted brother.
‘Seriously, I don’t even want to look at him.’
Yang Dami forced herself to turn her head and handed a lunchbox to Lee Yurim as well.
“I bought one for you too, Unnie. Here.”
“Hehehe, thanks. I’ll enjoy it.”
Unlike when she handed it to Yang Dajun, their hands touched softly. She didn’t have any particular ill will, so she had to treat her differently than her idiot ‘brother.’
“Dami, you’re so kind. You even bought ours.”
“…Of course I had to buy them.”
“Heh, please take care of us in the future too.”
“No? I’m not going to listen to your requests.”
I definitely didn’t buy it thinking of you.
I just bought it because I thought of it.
It was just obvious that Yurim Unnie was taking care of him, but he wasn’t even treating her properly as a guest, and that was so frustrating and shameful as a family member that she was trying to treat her at least this much!
‘Ah, anyway, I’m going to do whatever I want.’
Yang Dami muttered to herself with her head bowed, not even knowing what she was saying.
But Yang Dajun, thanking her anyway, approached her.
“Anyway, thanks. Heh….”
“Oh…?”
He stood on his tiptoes, got close enough for his breath to touch her, and reached out his hand.
“Oh…?”
And then, he placed his hand on her head and patted it.
“Eek?”
Yang Dami froze in place, receiving her brother’s touch.
She hunched her shoulders and bowed her head slightly.
She could see below.
“Huk….”
Her chin was tucked in, and her breath was blocked. Yang Dami’s eyelids trembled as if they were about to pour down, and she couldn’t keep her gaze steady.
‘Ugh, ugh… what is this, you idiot!’
Goosebumps rose along her spine.
It tingled all the way to the top of her head.
It echoed even inside her head, and every time her heart pounded, her hidden nipples felt like they were about to pop out.
“Huk, huk….”
Yang Dami felt the knot in her lower abdomen melt away, and her body grew hot.
“Yang Dami, what’s wrong?”
“Dami-ya?”
They asked in worried voices, but her mouth wouldn’t open.
When she tried to open it, it trembled, her teeth chattered, and it closed again.
“Huk, huuu….”
The world spun, and her breathing grew shallow.
Yang Dami didn’t know what to do, so she belatedly touched her hair.
‘W-what is this… why am I trembling so much! They won’t think it’s weird, will they? You idiot, what do I do, seriously.’
Her heart was pounding so hard that even her eyeballs were twitching.
Yang Dami wandered around and her gaze landed on her lower half again.
She let out a low sigh at the sight.
“…Ah.”
The place where Yang Dami’s eyes stopped was her ‘biological brother’s’ ‘that place.’
“Ah, ugh….”
She was so hot that even her ears were stinging.
Yang Dami gasped as if she’d been caught doing something wrong, then looked up again.
“Heh… why are you like that?”
He looked at her with an expression that said he didn’t understand.
Normally, this would be the time to shoot back with a sharp voice.
But Yang Dami stared at his face and then lowered her gaze again.
“Ugh, why do you keep looking like that.”
“Dami-ya?”
“Ah….”
Yang Dami, whose ears were ringing, blurted out something without thinking.
“Y-you idiot!”
Yang Dami spun around and ran straight into the bathroom.
“Hey, where are you going?”
“Dami-ya!”
The two called out, but she slammed the door shut.
Bang-
The bathroom was small and cold. Yang Dami leaned against the cold wall.
“Ha, haaa….”
Her chest heaved as she let out hot breaths through her small lips.
Her blood vessels were in such a frenzy that even her temples were throbbing.
Yang Dami’s chin trembled as she looked at the mirror in front of her.
“Gulp….”
She swallowed without realizing it and grabbed her top.
When she lifted her clothes, her pale white abdomen was revealed.
It was her lower abdomen, slightly protruding because it contained a womb.
Yang Dami, who placed her hand on it, trembled.
“I-is it bigger than this?”
Yang Dami, who had been pouting, lifted her arms further and pulled her clothes up to her shoulders.
Her ribs were slightly visible….
“U-up to here?”
Both her hands stopped dead.
She froze in place, having finished gauging the size.
Her lower abdomen was pounding, thump, thump, on its own.
Yang Dami stuttered and let out a belated sigh.
“Ha… t-this is ridiculous…?”
It was absurd.
“R-really ridiculous…?”
She took the hand that had been rubbing her lower abdomen and placed it back on top of her head.
It was the hair her ‘brother’ had touched.
“Ha, good grief… haha… ha….”
She swallowed a dry laugh and lowered her hand.
Her ears felt hot, as if they were swollen.
Her own breasts, which fit into her palms….
Yang Dami kneaded them with her hands and sighed secretly.
“Ha… haaa… ha….”
Yang Dami felt like her inverted nipples were about to pop out.
“Ha, haa… huuu….”
