One morning, not long after the new semester had started...
"Bro, wake up! Mom says it's time to eat!"
Jinwoo was still fast asleep when his youngest sister, Minji, came bouncing onto his bed, jumping on him to wake him up.
"Argh!! What the hell are you doing?"
Startled by Minji's sudden "splash" attack, Jinwoo, groggily but desperately, tried to push her off.
Young girls have no idea what young men go through.
The weight of Minji's thigh and the feel of soft flesh through the thin blanket was transmitted directly to Jinwoo's aroused cock.
Lying down, he quickly pulled up his knees to create some distance from Minji.
"Hey, didn't I tell you to stop doing this?"
Jinwoo, struggling to open his sleepy eyes, said to Minji.
"Hehe~ You can't get up if I don't do this."
Oblivious to his plight, Minji grinned innocently.
Seeing Minji leaning against his chest with his knees raised slightly, Jinwoo felt a renewed surge in his manhood.
"Get off, will you?"
Pushing Minji to the side amidst the chaos, Jinwoo caught his breath and thought to himself.
'Wow, that was close.'
Minji, now pushed aside, began pulling at the blanket Jinwoo was under.
"Bro, you need to get up, Mom said to wake you up~ I'll keep bothering you until you do."
"Alright, alright, I'm up, I'm up."
Jinwoo turned away from Minji, curling up and trying not to let go of the blanket.
He didn't want to expose his aroused state—though it might have been too late.
Minji began shaking the blanket back and forth again.
"You can't go back to sleep, bro~"
"Alright, I'm really up, I'll get ready and come down, just stop."
Jinwoo sat up with a look that seemed close to tears, clutching the blanket to him.
"Are you really up? Come down quick, breakfast is your favorite egg rolls and sausages."
Minji, with a devilish smile, headed downstairs, but Jinwoo's excitement showed no signs of subsiding.
Her whiny tone and expressions remained childlike, but her body was no longer that of a little girl.
Not quite mature yet, but definitely on the brink, ready to transform into an adult; a precariously mature girl's physique.
156cm. Quite tall for a 18 year old.
She'd always had great proportions—probably something she got from her mom.
Her face and personality were Absolutely adorable.
Honestly, even now, she was the kind of girl future boyfriends would go to war over.
*****
After Minji left,
Jinwoo calmed his erection by silently repeating the national anthem to himself three times.
Jinwoo's and his second sister Sohee's rooms were on the second floor.
The first floor had the master bedroom, the youngest sister Minji's room, and the room that used to belong to their eldest sister, Yejin—who now lived on her own.
After washing his face in the bathroom, Jinwoo headed downstairs.
At the dining table, Sohee and Minji were already seated.
Mom was sitting on the living room floor, sewing tools spread out, sewing a button on Sohee's school blouse.
"If you had told me the button fell off, I could have dealt with it, but just taking it off and leaving it in the laundry basket—what am I supposed to do with this in the morning rush?"
It seemed like mom's nagging had begun.
"I forgot to mention it~"
Sohee, sitting at the table and eating, turned apologetically towards mom.
"You've been told so many times to clean your room, but you just keep buying cosmetics and clothes? You don't listen, but you still think everything is fine enough for mom to sew your buttons in the morning?"
"I'll clean it up later~ I've just been so busy~"
"Quit sports and still this busy? And why would a perfectly good blouse button suddenly fall off? You're not gaining weight, are you?"
"Mom, it's not like that~ Why bring this up over breakfast~~"
Sohee looked hurt and complained to mom.
Last year, Sohee, now a freshman at the advanced school, had been an athlete.
She had never missed a morning workout, had won several competitions, and was considered a promising talent in sports circles.
But she had decided to quit athletics upon moving up to the advanced school.
Not long after dad's death, mom was understandably worried.
Though her career path wasn't set in sports, quitting something she had been committed to so suddenly was naturally linked to the loss of her father.
-Luckily, there was another reason-
Later, through a friend, it was revealed that it was because Sohee's chest and hips had grown too large.
Her chest and hips had grown too large...
Jinwoo casually glanced at his sister.
Even just wearing a T-shirt, it was clear her development was beyond ordinary.
The slim body shaped by sports was oppressively wrapping around a chest as large as soccer balls, practically bursting the buttons of her usual school blouse.
-In fact, they had burst before-
The curve of her large hips, rare for an Asian, continued from her slim waist.
It was definitely a trait inherited from the maternal side.
Just by looking at their mother and aunts, it was clear where it came from.
Sohee sitting there was a testament to how such blessed genetics could be sculpted through sports to such an extent.
Her shoulder-length hair, tinged with a hint of red, was styled in a chic way that parted on the sides, giving a clear view of her forehead.
Her dusky, tanned skin paired with well-defined muscles presented a refreshing and healthy appearance.
As Jinwoo joined the table, he teased his sister in a playful tone.
"Seriously, you've been eating a lot more lately."
"What are you talking about? I eat the same as before."
Sohee shot a fierce look at Jinwoo.
"That's the thing, you're not working out but eating just as much. You're bound to gain weight~"
Ignoring Sohee's glare, he continued while picking up his spoon.
"Hey! This isn't about getting fat, it's about my chest getting bigger, naturally filling out!! I still go jogging in the morning and do my workouts. You just stay up all night doing weird stuff and oversleep."
Sohee's voice rose.
"Enough, enough~!! Sohee, why do you keep yelling at your brother?"
As the noise escalated, their mother intervened.
"It's because Jinwoo keeps teasing me about gaining weight."
"To mom, it doesn't sound like teasing, just saying it as it is."
"Right, right, just saying it as it is, hehe."
"Damn it, look how annoying he is~! Why does mom always take Jinwoo's side~ See~?"
"Who's taking sides here? Jinwoo, stop pestering your sister!! Why do you keep provoking her?"
"Alright, alright, hehe."
"And why are you oversleeping again today?"
Mom's nagging shifted from Sohee to Jinwoo.
After a while of back-and-forth, mom finished her sewing and stood up, handing the blouse to Sohee.
"Big brother should set an example for his younger sister. Ah, our Minji is the most adult-like, not oversleeping and always listening well."
Mom stroked Minji's hair as she giggled 'hehe'.
Sohee, seemingly annoyed, pouted.
"That's because Minji has been sleeping with mom every night lately."
Since their father passed away, Minji had been frequently sleeping by their mother's side at night.
It was tough for everyone in the family, but Minji seemed to show it the most.
"Ah~ So sleeping in mom's room instead of her own at the age of a junior school 5th grader is being adult-like?"
Jinwoo spoke as if he found mom's attitude unfair.
"Oh my~ Jinwoo, you were clutching at mom's chest in your sleep until you graduated from junior school, and now you talk about others?"
Mom, displeased with Jinwoo's sarcastic tone, exposed his past like that.
"Jeez! That was just sometimes when scary movies were on TV back then. And it wasn't like I was grabbing on purpose, it just happened in my sleep."
Jinwoo was genuinely embarrassed as mom brought up his dark past.
"Kekeke, pathetic kid."
Sohee spoke with a look of disdain.
"Hehe~"
Minji still smiled innocently.
"Come on, you guys need to eat quickly and go to school~"
Mom sat at the table, smiling as if she found Jinwoo and the kids endearing.
This is just another chapter in the life of a loving family.
