The next morning
Jinwoo woke up before Minji came to wake him up.
It was 7:25 AM.
Just the right time.
In about five minutes, Minji would come up to wake him, and if he didn't get up then, she would return after ten or fifteen minutes to launch a body-slamming attack.
Memories of the previous day—specifically a furious masturbation session focused on his Mom—drifted back to Jinwoo like smoke as he came to his senses.
It wasn't a dream.
Sohee's disdainful look and her scoffing sighs confirmed that yesterday's events were real.
A chilling sense of shame, like ice needles jabbing his heart, proved that yesterday was definitely not a dream.
From today, Jinwoo must endure the humiliation Sohee will heap upon him.
JInwoo's cock was rock hard with morning wood.
Soon Minji would come to wake me up, and if he stayed like this, she'd definitely notice his erection.
Jinwoo was only wearing underwear, unlike usual.
After showering yesterday, he fell asleep in my room without dressing properly because his mom caught him in underwear.
"What a hassle!"
Regardless of the state of his cock, Jinwoo felt a sense of lethargy.
Why should he bother hiding it when a morning boner is a natural thing and it's his nosy little sister who intrudes into his room and disrupts his sleep?
Jinwoo decided to just stay as he was.
No! He decided to throw off the blanket and proudly display his majestic hard-on to his sister.
Jinwoo's cock was huge.
Not just among his peers, but on a human scale, it was considerably large.
Jinwoo never understood why his friends and older guys marveled at the size of cocks in porn.
Jinwoo quickly swept the blanket aside.
He adjusted the direction of his erection to make sure it was fully visible when Minji opened the door, then raised his arms to cover his face and pretended to sleep.
Minji would be overwhelmed by the sight of an unusually large, erect penis, certainly feeling embarrassed, and would give up on waking her brother.
It would be the first victory over his sister, who wielded their mother's authority to tyrannize him every morning.
How many minutes had passed?
Jinwoo waited in the same position.
Could a brother who shows his erect penis to his sister really be considered normal?
-I never really thought Minji was detestable-Minji would end up seeing his erected cock.
It was a giant tool meant for sexual pleasure, exposed just before insertion.
Suddenly, an erotic thought made his penis throb with blood.
Shame washed over him too.
"Could this become another irreversible dark chapter in my life?"
"What would happen if she told mom?"
"Should I stop now?"
While he was thinking this, Jinwoo's door suddenly opened.
"Brother, it's morning! Wake up~ We need to eat and go to school~"
Minji's cheerful voice could be heard.
"You'll get in trouble with mom if you oversleep again."
Minji approached Jinwoo, whether she saw his huge cock or not.
"Brother~ Brother?"
Minji gently shook Jinwoo's shoulders and chest.
His massive cock also began to shake.
Jinwoo had no choice but to desperately pretend to be asleep, whether Minji woke him or not.
After shaking Jinwoo, Minji stopped her hand and stood beside the bed for a while.
Jinwoo didn't care what happened; he just hoped Minji would leave the room soon.
After a moment, Minji bent down to whisper in Jinwoo's ear.
"You pervert..."
Jinwoo snapped to attention.
But he couldn't move.
Was that sound really from Minji's mouth?
Or was he dreaming again?
While he was thinking this, Minji straightened up and spoke cheerfully as usual.
"Brother, you need to wake up~ I'll come back in 10 minutes and if you're still sleeping, I'll torment you like yesterday~~ Got it?"
With that, Minji left the room.
Jinwoo opened his eyes and got dressed.
'It must have been a dream. It had to be. Minji wouldn't say something like that.'
Jinwoo reassured himself as he talked to himself.
* * *
I waited for my boner to go down before quickly showering and heading downstairs.
Mom and Minji were sitting at the dining table.
"Jinwoo, you're up? You got up right away today?"
Mom said with a smile as she ate.
"Yeah, Mom, did you sleep well? I slept so soundly last night that I woke up naturally this morning."
Jinwoo, seemingly conscious of Minji, was strongly implying to his mom that he didn't remember Minji coming to wake him up earlier.
"Bro, come on~~ Hehe, today's side dish is your favorite braised beef."
Minji greeted Jinwoo as usual.
-As if she hadn't seen his erect state earlier-
"Really? Did you help Mom with cooking today too?"
Jinwoo responded coolly, pretending everything was normal.
"Yeah, I'm learning a bit of cooking from Mom~ I'll cook your favorite dishes for you later~"
Minji made another impressive remark.
Jinwoo thought it was too calm and smooth for a conversation with a sister who had seen his erect cock.
As he was about to sit down, his sister Sohee was coming down from the second floor.
Sohee was wearing a white tank top that showed a lot of cleavage and pink training hot pants that clung to her body.
Like their mom, the sisters had quite ample breasts.
Sohee's large breasts, which fit nicely into her muscular frame, were barely covered by the white tank top, revealing almost half of them.
The pink training hot pants barely contained her big ass; the whole outfit was just too sexy.
Seeing his sister dressed in such revealing clothes made Jinwoo feel blood rushing to his cock again.
Jinwoo immediately pulled up a chair to sit down and try to hide his arousal from his family.
"Sis, you look really pretty, like a model! Hehe."
Minji complimented Sohee.
"Thanks~ You have an eye for fashion, don't you?"
Sohee happily accepted Minji's compliment.
"Where did you get that outfit?"
This time it was Mom who asked Sohee.
"Mom, isn't it pretty? I bought it when I went shopping with my friends! Hehe."
Sohee boasted to her mom, but her mom's expression wasn't great.
"Uh..um...but isn't it a bit thin to wear out?"
"It's okay, I'll only wear it at home."
"Ah...um...yeah, it suits you well."
Mom was about to say more but stopped and went to the kitchen to scoop rice from the rice cooker.
Jinwoo's gaze inadvertently followed Mom's ass before he quickly bowed his head.
He felt Sohee's gaze as she was about to sit across from him.
He looked up cautiously at her face, and Sohee snorted as if in disdain.
"Ha-"
"Why?"
Jinwoo asked indignantly, as if he had been wronged.
"I didn't say anything?"
"Why are you laughing?"
"I saw you bowing your head, thought you might have a stomachache..."
Sohee said with a wicked smile.
"If it's tough, why don't you ask Mom to rub your belly?"
Jinwoo, still hard, stumbled over his words in confusion.
"What...what are you talking about, I'm not a kid."
"That's right, you're not a kid anymore."
Sohee's words carried a deep meaning.
Jinwoo, confused, had no choice but to stare at his sister, speechless.
"Jinwoo, does your stomach hurt?"
Mom, having returned with the rice, put her hand on Jinwoo's shoulder and asked with concern.
"No~ It's just Sis saying weird things."
Jinwoo pulled his chair closer to the table to hide his erection from Mom.
"Damn it! Sis, stop picking unnecessary fights!!"
"Yaaawn~"
Sohee stretched, deliberately accentuating her breasts by interlocking her fingers and exaggeratedly throwing her arms behind her head.
The fabric of the tank top that covered half her breasts was pushed down by her bold stretching move, now precariously hanging just above the nipples.
Then she suddenly leaned forward, gathering her breasts to accentuate her cleavage, and said, "What? Did you call me?"
Jinwoo blushed and averted his eyes.
Seeing this, Sohee laughed triumphantly.
"Ha ha!! You're really funny right now, you know? You should've never messed with Sis from the start!!"
"What are you guys doing this early in the morning? Sohee, stop bothering your brother! Jinwoo, eat your food quickly!! Sohee, you need to finish eating and change clothes too~ Get ready for school!"
Mom intervened, seemingly pitying Jinwoo who was being weirdly teased by his sister.
From this point on, Mom started worrying about how to deal with Sohee's sexual jokes and pranks aimed at Jinwoo.
