Jinwoo went upstairs to grab a change of clothes and came back down.
He had planned to shower before Aunt Haeju and Sohee Noona arrived.
Tossing his clothes into the laundry basket in the changing room, Jinwoo stepped into the shower.
He turned on the water immediately.
As the temperature adjusted, a stream of hot water soon cascaded down over Jinwoo's body.
Under the spray, his massive cock stood proudly, rigid and imposing.
Before long, that thick, formidable penis would plunge ruthlessly into the bodies of the two women he loved, delivering them, and himself, waves of pleasure.
In Jinwoo's imagination, Aunt Haeju and Sohee Noona were barely able to handle his enormous length, taking turns moaning as they struggled to accommodate him.
The tight, wet grip of their pussies clung to his shaft, sending jolts of excitement through him.
Aunt Haeju's body trembled in response to his arousal, while Sohee Noona, with her delicate whimpers, tried to suppress the overwhelming pleasure of the thick flesh filling her, her face flushed, veins faintly visible.
In front of Aunt Haeju, Sohee Noona 's moans escalated into cries loud enough to fill the entire house.
Jinwoo gripped his cock and began stroking.
Masturbating while vividly imagining the two women—
The pleasure was so intense it felt like his very flesh might melt.
As the overwhelming urge to cum surged through him, Jinwoo stopped, his grip tightening momentarily before releasing.
**
Pushing back the wet strands of hair clinging to his forehead, Jinwoo tried to gather his thoughts.
Even in the midst of arousal, his mind was racing.
The text exchanges with his aunt…
Mom knew Sua was Dad's daughter, but she had no idea about what happened at the pension last year.
Which meant Dad had kept his sexual relationship with his own biological daughter, Yejin Noona, a secret from Mom.
At some point, Mom had been excluded from Dad's group sex sessions, whether with other family members or outsiders.
But that didn't necessarily mean she'd been freed from her submissive role to Dad…
According to Aunt Gyuri, it seemed the master-slave dynamic between Dad and Mom had persisted right up until his death.
Mom had only been released from her slave status because Dad passed away.
So even if Dad had secretly slept with Aunt Haeju, Aunt Gyuri, or other partners, Mom wouldn't have been in a position to interfere.
Was Mom's slave contract still hidden somewhere in the house?
What had happened to it after Dad died?
Earlier, while searching the master bedroom for the blindfold he'd use on Aunt Haeju, Jinwoo had deliberately scoured every corner.
*—Anywhere an A4-sized document could be stashed—*
Even as he looked for the blindfold, his mind kept circling back to Mom's slave contract.
Had Yejin Noona also had a master-slave relationship with Dad?
If so, there must have been a contract for her too.
When had Yejin Noona fallen into that kind of dynamic with Dad?
Suddenly, Jinwoo recalled a memory of Yejin Noona walking around the living room fresh out of the shower, wearing nothing but a towel draped around her neck.
Just a few years ago, in front of the whole family, she had confidently flaunted her voluptuous figure, striding through the house as if it were the most natural thing.
Her smooth skin, full breasts, the seductive curve of her waist leading to plump hips, and the occasional glimpse of her slit between her thighs as she moved…
It was as if she was spreading the scent of a female throughout the house.
Even as a young boy, Jinwoo had found himself mesmerized, his gaze helplessly drawn to her intoxicating allure.
Had that been around the time Yejin Noona and Dad started that kind of relationship?
Even before then, it hadn't been unusual for the family to lounge around in their underwear.
But no matter how open they were, walking around naked after a shower wouldn't have been allowed.
Running to their rooms while covering themselves would have been more normal.
For Jinwoo, that period remained a special memory, one where he'd caught multiple glimpses of Yejin Noona's sensual body.
Back then, he hadn't looked at her in a sexual way, but now, recalling those mesmerizing moments, Jinwoo gave his still-hard cock another firm stroke.
Would he ever get to thrust his massive length into that alluring slit of hers?
The thought sent a thrill of excitement through him, his thick shaft pulsing as depraved, intoxicating desire spread through his body.

Finishing his shower, Jinwoo stepped into the changing room to put on the clothes he'd prepared.
Just then, the sound of the front door opening reached him, followed by familiar voices.
"Jinwoo~ we're heeere~! Hehe~"
Aunt Haeju's playful, slightly tipsy voice announced their return alongside Sohee Noona.
"Oh! Aunt Haeju, you're here?"
Still naked, his cock standing proudly, Jinwoo answered from inside the changing room.
"Oh my, our Jinwoo's already showered? Feeling frisky, huh? We were gonna eat first and shower after~ Right, Sohee-Hic~?"
Aunt Haeju teased in a mischievous tone, as if making a dirty joke to her nephew.
"I—I thought you and Sohee Noona would take longer… Wait, Auntie, have you been drinking?"
Jinwoo responded, slightly flustered by her unusually bold humor.
But despite his shyness, his cock twitched defiantly, as if reacting to Aunt Haeju's audacity.
"Of course I did~ With Sohee~ Kikik~ Since we're already like this, why don't we just go in and help Jinwoo shower? What do you think, Sohee?"
Aunt Haeju's provocative joke, clearly meant to tease Sohee Noona.
"W-What are you saying, Aunt Haeju?! W-We agreed to eat first~!"
Sohee Noona raised her voice in flustered protest.
Seemed like something had gone down between them before coming home…
"I—I'm already done showering! I'm just getting dressed now…"
Jinwoo, too, sounded caught off guard by the sudden turn.
"Oh? Well, guess we have no choice then~ Kikik! I'll go get dinner ready~!"
Aunt Haeju's sly voice faded as she walked away.
Jinwoo suppressed the urge to storm out right then and bury his throbbing cock deep inside her. Instead, he picked up his clothes and got dressed.
**
Jinwoo put on a loose black T-shirt and gray shorts.
Fully dressed, he left the changing room and headed to the living room.
Jinwoo's erect cock seemed about to burst out of his loose clothes.
But Jinwoo no longer cared about such things in front of his lovers.
In the kitchen, Aunt Haeju was scooping the chicken porridge she had brought into bowls.
Sohee was nowhere to be seen, not in the living room or the kitchen.
"Where's Sohee Noona?"
Jinwoo asked Aunt Haeju as he walked towards the kitchen.
"She went upstairs to her room~ Said she's gonna shower right away and went to grab a change of clothes~"
Glancing at Jinwoo as she answered, Aunt Haeju's lips curled into a faint smile when she noticed his obvious bulge.
"Aren't you gonna shower?"
"Aren't you hungry? I'll eat first and shower after. Let's eat together when Sohee comes down, okay? You're eating first too, right?"
Her use of "you" had become so natural, as if there were no other option.
"Uh… yeah… okay."
Jinwoo replied, somewhat taken aback.
His eyes landed on the pile of shopping bags near the dining table.
Jinwoo sat down at the seat opposite Aunt Haeju and looked inside the shopping bags.
Clothes with tags still attached, likely new purchases from the department store.
"Did you go shopping with Sohee today?"
Jinwoo deliberately left out the title "noona" when asking Aunt Haeju.
"Yep~ Wanted to chat and cheer her up a bit~ There's something for you too, so check it out later."
Aunt Haeju continued effortlessly, as if they'd always spoken this casually.
"What did the hospital say? Will there be any records if you get a prescription for something like that?"
Jinwoo asked, sounding concerned.
"A record? Oh, don't worry about that~ We didn't go to the hospital today."
Aunt Haeju replied cheerfully.
"Wait, so where'd you get the meds?"
Jinwoo sounded puzzled.
"I got the medicine from someone I know."
"Someone you know? Who?"
"That's a secret~! Kikik!"
Aunt Haeju laughed mischievously.
Her playful response only stoked Jinwoo's sadistic urges, his cock swelling even harder as dark, depraved desire coiled through him.
**
As Jinwoo was talking to Aunt Haeju, his smartphone vibrated.
He opened his phone to see a message from Sohee with a photo attached.
The photo showed the inside of Sohee's dresser drawer.
Her underwear was soaked with his's semen.
'Ugh, seriously, what the hell!'
Sohee Noona's text radiated frustration.
'Hehe, did you see it? I couldn't help it while thinking about you in your room.'
'You could've taken one to jerk off into! How am I supposed to change now?!!'
Sohee's extreme annoyance was evident in her text.
