Jinwoo carried the tools downstairs to the first floor.
Without hesitation, he headed straight to Minji's room.
The moment he stepped inside, Minji's bed came into view.
Jinwoo recalled the sensation from last night—
The feeling of his penis pressed against Minji's lips as she slept.
Her mouth, clinging tightly to the head of his cock, sucking with a delicate pressure that seemed to milk out his very essence.
The soft, wet warmth of her inner cheeks and the rough texture of her tongue.
Just reliving that maddeningly exquisite sensation sent a dizzying thrill through his body, making him tremble with the urge to cum right then and there.
It hadn't been long since he'd ejaculated in Sohee noona's room,
Yet his huge cock was already stiff again, throbbing as if ready to explode.

Jinwoo set down the items he was carrying onto Minji's bed.
Then, he moved toward the bookshelf on the left side of the bed, pulling open the drawer beneath it.
Rummaging through its contents, he found it stuffed with highschool textbooks and miscellaneous knickknacks.
Buried among them was a coiled-up orange jump rope, its glossy surface catching the light.
He reached in, digging deep to pull out Minji's jump rope.
With it in hand, he returned to the bed, placing the coiled orange rope alongside the other tools he'd laid out.
The jump rope, condoms, a remote-controlled vibrator, and the adhesive bands to secure it to skin—
Staring at the array of items on the bed, Jinwoo imagined Aunt Haeju bound and ravaged by him.
Aunt Haeju, stripped of dignity, arms and legs tied behind her back, struggling to keep balance as her chest and groin were exposed, forced to lie back helplessly in front of her niece and nephew.
The humiliating image made Jinwoo pull out his cock, stroking it up and down in a strange, self-soothing act of masturbation.
After a while, he suddenly realized he was missing one crucial item.
pulling up his pants, he left Minji's room and headed to the master bedroom.
The moment he entered, he began searching through every drawer—
The nightstand, the wardrobe, even his mother's vanity.
What he was looking for was inside the vanity drawer:
The lavender silk sleep mask borrowed from Aunt Gyuri.
The very same mask he'd torn off his mother during sex and carelessly tossed onto the bed just before cumming.
His mother, in her frantic cleanup of the bedsheets and blankets, must have neatly stored it away in her vanity.
Jinwoo planned to use it today, to blindfold Aunt Haeju.
With the mask in hand, he returned to Minji's room.
The tools for tonight's activities were now spread across the bed like a display.
What exactly did Jinwoo intend to do with them?
Interrogation? Torture? A clumsy imitation of BDSM?
Even he wasn't entirely sure.
But one thing was clear, the burning desire to shatter Aunt Haeju's composed, adult facade.
That urge squirmed inside him, undeniable.
Leaving the tools where they were, Jinwoo stepped out into the living room.
**
The remnants of last night's frenzy still littered the living room and kitchen.
Deciding to use the remaining time wisely, Jinwoo resolved to clean up the mess.
He dumped the leftover food and trash from the dining table into a garbage bag.
Carrying the dishes to the sink, he wiped down the table and floor with a wet cloth.
Then, he washed the piled-up dishes and put them away.
As he worked, his mind wandered to what would happen once Aunt Haeju and Sohee noona arrived.
Would they eat dinner together at that very table before moving straight to sex?
Would he take turns fucking them, scraping his cock against their inner walls, listening to their moans intertwine?
He'd already slept with both Aunt Haeju and Sohee noona separately.
But the idea of being with both at once still felt awkward.
Should he suggest they all shower together?
Or would it be less strange to take turns in separate rooms?
Aunt Haeju probably wasn't unfamiliar with threesomes or group sex.
And Sohee noona had been in a long-term lesbian relationship with Shin-bi noona.
If she had no reservations about being with her aunt, maybe the three of them could naturally transition into a sexual routine.
Maybe he'd even get to see Aunt Haeju and Sohee noona in a 69, pleasuring each other with their mouths…
**
After finishing the cleanup, Jinwoo slumped onto the living room couch.
Half-lying down, he pulled out his phone and began scrolling through the recent files he'd acquired, evidence related to the mothers.
Starting with the slave contract for Aunt Gyuri, received from Daeho, to the orgy video at the pension sent by Aunt Haeju,
and even today's photos of his mother's slave wedding ceremony along with the vows they'd written.
These videos, photos, and documents were undeniable proof of the mothers' depraved cartel.
Putting it all together, it was clear, his mother, Aunt Haeju, and Aunt Gyuri had been sharing each other's dark secrets all along.
The slave contract he'd first discovered,
the pension video from Aunt Haeju, questions he should've asked long ago.
Now, under the guise of play, he wondered if he could finally confront Aunt Haeju.
The obscene photos of his mother and Aunt Gyuri, wearing nothing but veils, collars, and metal rings, lost in each other's bodies.
His mother's past, whether by choice or force, had been exposed to him today.
Jinwoo knew there was no turning back now.

"Haeju, where are you? On your way?"
Jinwoo texted Aunt Haeju.
"Yeah~ baby! Sohee and I just finished our date. We stopped to get some chicken porridge, so we're heading back now~"
Her reply came instantly.
"Did you take care of the pill?"
Jinwoo checked about the morning-after pill.
"Yep~ All taken care of! No need to worry!"
Aunt Haeju mixed casual and polite speech in her response.
"How's Sohee noona feeling? Is she okay?"
He was concerned about the side effects of the emergency contraceptive.
"Yeah, seems fine."
"Good. If anything happens, you better take care of her, got it?"
Jinwoo texted as if giving orders.
"Got it~ baby. I'll take good care of Sohee~ Don't worry!"
Aunt Haeju replied playfully.
"But now that Sohee's yours, you're still fussing over her even when I say she's fine?"
She teased him further.
"Huh?"
Jinwoo reacted, flustered.
"Before, you two would bicker all day if left alone~ Now you're making me a little jealous~?"
Her texts continued, dripping with playful sarcasm.
"No, it's not like that! I just feel bad because I fucked her senseless all night, so I'm checking in! Why are you getting jealous over this?!"
Jinwoo defended himself, slightly panicked by her pouting tone.
After a brief pause, Aunt Haeju replied:
"LOLOLOL~ Ah, so funny! I was just teasing~ Like aunt, like nephew~ Why would I be jealous of Sohee? LOLOLOL"
Her laughter-filled text was lighthearted.
"Ugh, what the hell?!"
Jinwoo felt a flash of irritation at being toyed with.
"Sohee's my niece before she's your girlfriend LOL Did you really think I'd be jealous? Even if you didn't say anything, of course I'd look after her~"
Though she mixed polite speech, her tone was subtly patronizing.
"Stop messing around!"
Jinwoo snapped.
"Hehehe~ Okay, okay~ I won't tease anymore, honey~"
She switched to a sweet, faux-innocent tone.
"So when are you getting here?"
"We're close, so maybe 30 minutes?"
"Alright, be careful with Sohee!"
"Yeah, see you soon~"
With that, their back-and-forth banter ended.
**
After the exchange, Jinwoo paused to think.
The questions he should've asked after receiving that shocking video last night…
"Can I ask you something?"
He texted Aunt Haeju, deliberately keeping the formal "Aunt" title.
"Of course~ What's on your mind, Jinwoo?"
Her response was free of teasing this time.
"You know Su-a's dad, right?"
Jinwoo typed slowly.
"Yeah."
"Is he someone I know?"
After a long hesitation, he finally asked.
"Yeah."
She answered without resistance.
"Is it who I think it is?"
Jinwoo danced around the subject.
"Yeah. Probably."
Her reply was straightforward.
"Does Mom know?"
"She does."
"What about what happened with Yejin noona at the pension?"
"She doesn't know about that."
Answers he'd vaguely expected for a while now.
Without hesitation, Jinwoo sent Aunt Haeju the photos he'd taken of Aunt Gyuri earlier.
Pictures of Aunt Gyuri, legs tied back, chest and groin fully exposed,
ass raised high, face buried in the couch, wrists bound between her thighs,
mouth and pussy smeared with cum.
Then, the photos of his mother's slave wedding ceremony received from Aunt Gyuri.
Followed by the marriage vows between him and his mother,
and finally, Aunt Gyuri's slave contract.
The (1) notification disappeared, but no immediate reply came from Aunt Haeju.
—As if waiting for Jinwoo to speak first—
"You better brace yourself when you get here! I won't forgive any of you!"
After a long silence, Jinwoo sent a domineering message.
"Yes, Master."
Her eventual reply sent a thrilling shiver through him.
His cock swelled, harder than ever, ready to burst.
