On his way home, Jinwoo was already hard, staring at Sinbi noona's photo.
The kiss mark nestled between Sinbi noona's breasts…
Just imagining how that mark had been made caused his lower half to swell even more.
Sohee noona, glancing around at the people nearby, undid Sinbi's buttons and pressed her lips to her exposed skin.
Her plush, soft lips met Sinbi's smooth flesh, sucking with enough force to leave behind faint red marks.
When she was with Sinbi, Sohee noona seemed bolder than usual.
Perhaps as early as tomorrow, Jinwoo might get to see that secret mark with his own eyes.

It seemed there was no changing Sohee noona's decision to stay the night at Sinbi's place.
Jinwoo struggled to calm his unyielding arousal as he headed home.
Holding his bag in front of him to hide his bulge, he moved slowly.
Then it hit him, he was heading back to an empty house.
A hollow, lonely feeling suddenly washed over him.
Ding!
Just then, his phone buzzed with a message notification.
He checked the screen.
"Master~ Did you finish your classes?"
It was a cutesy text from Haeju, his aunt.
Jinwoo felt unexpectedly comforted by Aunt Haeju's message.
"I just finished, heading home now. Why?"
Jinwoo responded to Aunt Haeju's text with a deliberately dry tone.
"You're alone tonight, right?! I was thinking of stopping by with Sua and Minji, would that be okay?"
Aunt Haeju seemed to already know Sohee wouldn't be home, asking for permission like this.
"Uh… with Sua and Minji? Coming over? What time?"
Though he was extremely happy, he kept his tone dry and uninterested.
"Around 6, before dinner. Just for a little bit."
She gave him a specific time.
"But why are you bringing them?"
Jinwoo couldn't help but ask.
"Sua and Minji said they have something to give you~"
Haeju replied immediately.
"For me? What is it?"
Curious, Jinwoo pressed.
"They made something at their magic class and insist on giving it to you today. Can I bring them?"
Obediently answering his questions, she asked again.
Haeju noona seemed to have fully abandoned her aunt status, now acting completely submissive toward him.
"Yeah… fine. 6, right? Oh, are you still wearing that vibrator I told you to?"
He granted her request but then recalled yesterday's command…
The order for Haeju noona to always keep a vibrator inside her.
"It's charging right now~"
She confirmed she was following his instructions.
"Haeju! Finish charging it, then put it in before you come with Sua and Minji! Got it?!"
A mischievous grin spread across his face as he imagined her struggling to hold back moans in front of the girls.
"Yes~ I'll do as you say, Master."
She replied without protest.
Hearing this, Jinwoo adjusted his stiffening bulge and quickened his pace home.
The thought of seeing his beloved cousins soon washed away the gloom Sohee noona had left behind.

Upon arriving home, Jinwoo dropped his bag in his room on the second floor and gathered clothes to change into for a shower.
Carrying his fresh clothes, he went back down to the living room.
His eyes landed on the sink, the dishes he hadn't managed to clean up in the morning rush were piled inside the sink.
Jinwoo threw his clothes on the living room sofa and headed to the kitchen to do the dishes first.
After tidying the mess, he prepared to welcome the girls into his now fully controlled, secret domain.
Once done, he grabbed his clothes and headed to the shower.
The moment he stepped into the changing area, a musky scent hit his nose.
The source seemed to be Sohee noona's orange panties in the laundry basket…
The lingering smell of their old bodily fluids, unnoticed in their hurried morning wash.
Aunt Haeju must have moved them there to wash later.
Maybe she hadn't had time to run the machine before leaving.
As Jinwoo reached to transfer the clothes, he paused.
What if the girls smelled his dried cum on Sohee noona's panties?
Just yesterday morning, Minji had come to wake him up, and Jinwoo had almost exposed his erection to her…
Though still hidden under his underwear.
Staring at the orange panties, the sinful thrill of that moment resurfaced.
The idea of revealing last night's events to his cousins made his cock throb harder.
He placed Sohee's panties on the side table.
Then, pulling down his pants, he freed his cock and gripped it.
Imagining Sua and Minji arriving in an hour, he began stroking.
His hand moved faster, tightening around his shaft, pulling him closer to release.
Squelch! Squish! Splurt!
Finally, Jinwoo spilled his hot, milky fluid onto the orange fabric.
Sohee's underwear was splattered with Jinwoo's white semen.
As Jinwoo's semen slowly soaked the orange fabric, feelings of guilt and thrill simultaneously seeped into his heart.
Leaving Noona's cum-soaked panties behind, he stepped into the shower.
The hot water washed away the remnants of his guilt, or at least, he pretended it did.
**
Jinwoo finished showering and sat on the living room sofa looking at his smartphone.
Lewd, incestuous photos and records of his mothers' past…
Most of it detailed the tangled, secretive relationships within his family.
His mother, pregnant with him, had undergone a slave wedding ceremony.
And it seemed she was the one who had dragged Aunt Gyuri and Haeju into this world.
At first, Jinwoo had dismissed it as just extreme roleplay among family.
He had tried to ignore it.
But as more secrets surfaced, the discomfort grew harder to shake.
When had all this started?
From what Haeju and Gyuri had said, it must have begun even before his mother met his father.
A hidden network of acts and relationships that extended beyond family…
Involving not just his mothers but also his father's acquaintances.
Maybe even neighbors or people Jinwoo didn't know.
This wasn't just play. It was something far larger, something that had already seeped into his reality.
At the very least, the slave contract Daeho had sent, Gyuri's contract, was the root of his unease.
The agreement between Gyuri and Daeho's father, Kyuhyung, included not just details about Jinwoo's dad but also names he didn't recognize.
Jinwoo was looking at Aunt Gyuri's slave contract on his smartphone screen.
He remembered Daeho's words, that there should be two copies of the contract since it's an agreement between two parties.
Did that mean a second document existed?
Among those involved, these slave contracts seemed to hold real weight.
But to outsiders, they'd just be meaningless scraps of paper.
After all, wasn't this just an elaborate game of roleplay fetish.
Yet Daeho insisted that, following real-world formalities, master and slave would each keep a signed copy.
Was that claim just Daeho's simple speculation?
Jinwoo zoomed in on Aunt Gyuri's slave contract.
And he began to meticulously examine the content.
