The Nurturing Method for a Lackluster Younger Sister
"What are you doing?"
"Ugh… isn't it obvious?"
"Why are you holding on to that spot?"
The place I pointed at was her nipple.
A puffy areola concealing a nipple that had sunk inward, hidden away despite the swelling.
At my words, Yang Dami let out a long breath before answering.
"Haah… I'm loosening up the lump, obviously. Do I have to spell it out for you?"
"No, that's kinda weird, isn't it?"
"What's weird about it? You just keep kneading away."
Yang Dami brushed me off as if my objection weren't even worth a response, then grabbed my hand.
And then she placed it on top of her own chest and made my knuckles knead at her breast.
"Like this. Keep doing it like this."
Her voice was crisp and curt, but there was something undeniably cute buried in it too.
So I did as Yang Dami instructed and worked her breast in my hand.
Squish, squish…
'It's like a little ball of rice cake.'
A small chest, but perky where it counted, sitting up nice and firm.
Yang Dami, meanwhile, was playing with her own nipple.
"Mmnh…."
Rolling it around in a circle,
"Hnngh…."
pinching down hard,
then squeezing and twisting it sideways.
"Haahk…!"
Her nipple had sunken in, and it looked like she was trying to coax it back out.
A little sister offering her chest up to her brother while she touched herself.
Soft whimpers leaked out from that tiny mouth of hers.
"Mmmh… nnghh…"
Yang Dami pressed down on her breast with a dissatisfied look and shot me a sidelong glance.
"…It's not working."
She muttered to herself as she squeezed her breast forward in her hand.
That flickering, crab-eyed stare made me nervous, so I pretended not to notice.
"What do you want me to do about it?"
"Hmph, you're hopeless…."
Yang Dami stuck out her lips in a pout.
Then she suddenly snatched up my fingers.
"Moron, I'm telling you to do it for me."
"Hey… that's a step too far, isn't it?"
Yang Dami pressed my fingertip against her own nipple, and I grimaced and tried to yank my arm away.
But Yang Dami just played it cool.
"What about it?"
She said it with perfect calm, as if she couldn't comprehend my objection.
"Don't go getting weird ideas. Touching this spot is just part of self-care."
"Self-care? This?"
"You've never heard of corrective exercise? I can't do it right on my own, so I'm asking you to help."
I was left staring at her, dumbfounded.
'She's got some nerve, that face of hers. If I call this out, I'm the one who'll end up looking like the pervert here.'
A little sister who wants her brother to play with her nipples as "self-care"… this was a tough one.
Left with no choice, I flexed and unflexed my fingers, stalling for time.
Unable to watch anymore, Yang Dami tilted her chin up and urged me on.
"Hurry up and do it already."
"…Tell me if it hurts."
With that, I reluctantly spread two fingers apart.
An adorable little chest, with a nipple sunken into it.
I pinched my little sister's inverted nipple.
"Hah!?"
The moment I applied pressure, a sweet whimper burst out of her.
"Hnnngh…!"
"Ah, sorry—"
"Your… your hand! Moron! Don't you dare stop, ahhh…!"
Yang Dami grabbed my wrist and snapped at me in a shrill voice.
'Guess even girls have their pride.'
Though by the end, her voice had gone small and creeping.
Yang Dami slowly closed her eyes, her expression melting into something soft and gooey.
"Hnnnh…."
She even wriggled and squirmed as if she were being tickled.
Every time I touched her, the nipple that had been hiding inside peeked out a little further.
Her Affection had gone up.
'As expected.'
I watched my little sister's face come apart in a blissful, melting smile under my touch, and thought,
'I think I'm right about this.'
Just like my 'older sister,' my 'little sister' seemed to have developed feelings for me too.
Both sisters seeing me as a man….
The back of my neck prickled with tension.
'For now, I should act like I haven't noticed.'
Knowing Yang Dami's personality, she'd be mortified if I let on.
Things could turn even messier than they did with Yang Dahee.
I kept my expression stiff and tried to pull my hand away, but—
"Don't…."
Yang Dami caught my hand and pushed her lips out in a pout.
"Don't take your hand away…."
"That should be enough, right?"
"Mmmmmh…."
She shook her head slowly, eyes fixed on me.
I sat there facing her, Yang Dami sprawled half-reclined in front of me.
"Moron…."
Yang Dami batted her lashes and grabbed my wrist.
She pulled my hand up and set it on top of her head, then started rubbing her own head against my palm.
"What are you doing?"
"Shut up…."
Every time my palm brushed her hair, she let out a little purring sound like a cat.
"Hnngh…."
Yang Dami slowly closed her eyes.
Kneading her own breast with one hand, she soaked up my touch with the other.
'Dami, please, let's just let this pass peacefully.'
Face frozen, I stroked her hair.
Yang Dami felt like her nipple was about to pop right out.
That itchy, restless feeling was welling up from beneath her chest, and she wanted Yang Dajun to keep touching her.
'Don't take your hand away. My breasts are going to get bigger too….'
She wanted him to touch her hair as well.
'Hurry up and pet me. Tell me I'm a good girl.'
Having her head stroked made her feel like she was being acknowledged—as his little sister.
Yang Dami rubbed her head against Yang Dajun's hand, sneaking glances up at him between nuzzles.
"Mmnh… hm…?"
'What's with him? Why is his face totally blank?'
He was a guy, and here he was touching a woman's body without so much as a blush.
Yang Dami had never been in a relationship herself—still a virgin—but she'd simply assumed Yang Dajun was a natural-born innocent, too naive for his own good.
So she decided to push her luck a little further.
"Haah. I wanna lie down."
She sprawled out on her back and pulled Yang Dajun toward her.
"This is a bit much. This position is weird."
"It is not weird at all? Honestly, what is going on in that head of yours?"
Even as she spoke, her heart was pounding like a drum.
She told herself her ragged breathing was just because she was lying flat on the floor.
'Yang Dajun, you moron.'
Looking up at him from below, her lips couldn't help but jut out in a pout.
Yang Dami turned her head to the side and spoke.
"Knead them properly this time."
"Is this seriously the last time?"
"Like you've done all that much? Whatever, just do it right."
A man's hand came to rest against her bare upper body, not a single thread covering it.
"Haah."
She glanced at Yang Dajun; his lips were pressed tight, like the effort was getting to him.
Every time he pressed down with his hands, her breath broke loose in little gasps.
'Hnnh….'
Yang Dami held back a giggle that threatened to escape.
Because Yang Dajun—the boy who always clung to their older sister—was, just for this moment, working hard for her sake alone.
And Yang Dami found herself wanting to chase away the anxiety gnawing in a corner of her heart.
"Hey."
"Hm?"
Yang Dajun frowned and looked back at her.
'Moron, if you're tired, just quit when you've had enough.'
But he just kept kneading away, doing exactly as he was told.
Watching him, Yang Dami asked carefully,
"Yang Dajun… you're not going to disappear, right?"
"Obviously not?"
"Hahh…."
Moron, you're supposed to at least hesitate.
He clearly had no idea what she was getting at.
'I'm asking if you'll vanish like Mom and Dad did, you idiot.'
Even their own parents had abandoned their children and walked away.
Such an easy answer left her anything but reassured.
Yang Dami ruffled her own hair into a mess.
'Moron. You should ask for proof, at least.'
Yang Dami slowly lifted her eyes.
Above her, Yang Dajun was looking down at her.
"Dami?"
For some reason, her chest felt tight and constricted.
She stared at Yang Dajun.
'A kiss….'
Her tiny lips trembled.
'I want to kiss him….'
Yang Dami parted her lips slightly.
Her hand reached out toward Yang Dajun, almost without her meaning to.
"Hm?"
Their eyes met.
"What are you doing?"
"…!"
Yang Dami's ears flared scarlet.
A rush of heat climbed up her face, making her eyelids flutter and tremble.
'Sh-Shit, I've lost my mind!'
She'd almost kissed her own older brother.
She glared daggers up at Yang Dajun.
'…Yang Dajun?'
Her face was burning, and all he could do was tilt his head in confusion.
Yang Dajun asked,
"What's wrong with you?"
"Sh… shit…."
At that, Yang Dami bared her teeth.
"You…"
"You what?"
She glowered at the oblivious Yang Dajun, then simply screamed the rest at the top of her lungs.
"YOU IDIOT!!"
"Wha—?"
She headbutted him straight in the forehead.
CRACK!
It sounded like a watermelon splitting, and Yang Dajun swayed on the spot.
"Aaargh…."
"Move!"
Yang Dami sprang to her feet and shoved him aside.
She flung her clothes over her face and bolted into the bathroom.
She slammed the door shut behind her.
Yang Dami leaned against the wall, gasping for breath.
"Shit… goddamn shit…."
Her chest felt like it was about to burst.
Yang Dami thought of her own older brother.
"Moron, Yang Dajun you absolute moron…!"
His lips kept floating up into her mind, no matter how she tried to shake them away.
"Total IDIOT!!"
"Wow…."
I staggered into my room.
'That hurt like hell. My stomach's churning too.'
Rubbing my forehead, I shut the door behind me.
I sank onto the bed and let out a long sigh.
"Ha… all things considered, I got off easy."
The mood had almost broken completely.
She'd sprawled out beneath me, and then suddenly reached her hand up—
'Yang Dami tried to kiss me. She got embarrassed and ran off on her own, but still.'
I let out a long breath and thought it over.
She's a girl right at the age when romantic feelings first take root.
Those feelings must have gotten tangled up with her love for family.
'I can't just flat-out reject her.'
Not when she might react as extremely as Yang Dahee did.
I decided I'd handle Yang Dami gently—coax her, soothe her, never corner her.
'For now, I need to get out of here.'
I picked up my phone and checked the time.
It was time to meet Lee Yurim.
I'd go to her place today.
'I can text her on my way out.'
I got dressed and opened the door.
On the floor, Yang Dami sat hugging her own clothes tight to her chest.
She looked up at me and asked flatly,
"…Where are you going?"
A little sister who demands a full itinerary every time her brother leaves the house….
I answered as casually as I could manage.
"Yurim's place."
"Hahh… fine. Go, and don't come back."
Where was all this now, when she used to blow up my phone with texts telling me to hurry home?
I skirted around Yang Dami as she ruffled her hair into a mess and glanced around the floor.
'A USB?'
Must be my older sister's.
I passed it without a second thought and put on my shoes.
Yang Dami watched me the whole time, grumbling to herself.
'Guess she doesn't like it when I go outside.'
I just lifted my head and looked at her.
"I'll be back soon."
I said it with a smile, half to placate my little sister—but her answer was the last thing I expected.
"Don't come back!"
"Huh?"
"I said don't come back! You'd better hurry up and get home early, or else!"
Yang Dami shrieked loud enough to bring the whole house down.
She kept twisting her words so it sounded like she was telling me to come home late, and I got the feeling something was about to come flying at my head if I lingered, so I scrambled out the door.
Right up until it closed, Yang Dami was clutching her clothes in a death grip.
"Heh heh… guess I can't tease her any harder than that."
Halfway down the stairs,
I smirked to myself and typed out a text.
A heads-up text should do the trick.
Lee Yurim's parents would have already left for work by now.
'Guess I'm about to get thoroughly devoured.'
Rolling around with Lee Yurim would take the edge off, at least.
Pleasant thoughts in mind, I pressed send.
And then—
Bzzz.
Bzzz.
'?'
A vibration was coming from somewhere very close by.
The very instant my text went out, a phone was buzzing.
A chill ran down my spine.
