Chapter 415 (Mom)

[I went through all the trouble of stripping you, so why’d you leave your clothes there? Since you’re already naked, I’m thinking of just making you walk home like that~ haha.]
Si-woo was teasing his mother with words that left her unsure whether he was joking or being dead serious.
[Stop joking around! I feel like I’m losing my mind as it is! Stop saying such ridiculous things and bring my clothes here right now!]
His mother replied, her words practically bursting with indignation.
[Who said I was joking? Haha. I already left that room ready to head home. You saw me grab my bag and walk out, didn't you?]
[I was just thinking about it, but seeing how you’re acting, I think I should just go straight home! I’m heading back now, so you just take your time and come back whenever you’ve calmed down~]
Si-woo spoke to her as if he were bluffing, making it sound like he was truly on his way home.
[What? How can you just leave in the middle of everything?!]
[How am I supposed to get home in this state?! If I run into someone I know on the street, it’ll be a disaster!]
His mother sent the messages in a frantic rush.
[That’s for you to figure out! I can’t solve every little problem for you, can I? Anyway, I’m heading home first. Be careful on the walk back~ It’s going to be pretty chilly walking around like that~]
Si-woo continued to speak as if he were actually returning home.
Of course, he had no intention of actually leaving his mother alone at the karaoke room and going home. He was simply lying about leaving to push her into a psychological corner.
[Si-woo, what are yuo talkign about? Do yuo really want to see Mom go crazy?]
His mother sent a message riddled with typos, making it clear how desperate and confused she was.
Even after seeing her frantic message, Si-woo didn't respond immediately.
Just as she had taken her time to reply to him earlier, he intentionally ignored her message for a while.
Staring down at her last text, Si-woo imagined the confusion, frustration, and humiliation she must be feeling—and the unique, perverted masochistic pleasure she would be experiencing as a slave.
His rock-hard penis throbbed with another surge of heat.
At the same time, a satisfied smile naturally spread across his face.
Si-woo minimized the chat window and pulled up the vibrator control app.
Instead of replying to the text, he placed his finger on the screen and cranked the intensity up several levels at once.
Si-woo’s smartphone vibrated so violently it felt like it was rattling his bones.
The vibrator inside his mother was likely vibrating even more intensely than his phone.
The powerful vibration continued for quite some time.
Then, his phone, which had been vibrating intensely, began to ring loudly.
It was a call from his legal wife and bitch slave—his mother.
Si-woo let it ring five or six times, drawing out the tension, before finally answering.
"Hello? Mom? What’s up? Why are you calling?"
Si-woo answered with a nonchalant voice.
"Si... Si-woo... are you really... ngh... going to do this to your mother?"
His mother’s voice sounded as if she were on the verge of bursting into tears.
"Do what? You said everything you wanted to say, didn't you? I figured we were done, so I was just heading out. Why?"
Si-woo spoke in a rebuking tone, criticizing her earlier rebellious attitude and demands.
"We... we were still mid-d... discussion! Hngh... You said we’d talk about... ah... posting the photos and videos to the group chat... after I came back from the... bathroom! Ngh! We weren't finished yet... so how can you just... ah... strip me like this and... just leave? Haa-ah!"
She sounded resentful, as if it were unfair of him to leave her abandoned and irresponsible after they had agreed to continue their talk.
"Oh, that? I thought about it, and I figured you wouldn't listen to me anyway, so I decided to drop it."
"You said you didn't want them posted in the group chat, right? I didn't feel like having a pathetic argument with you about it~"
"I figured it’d be faster to just go home and show the videos to Se-hee and Se-young while you're not there and explain it to them myself. I have to tell them about the new rules we set earlier anyway."
"Don't you think it’ll be much easier for them to understand if I give them a live explanation while they watch the videos and photos?"
Si-woo provoked her with a sarcastic tone, testing her reaction.
"Si... Si-woo... M-Mom was wrong... hngh... I thought you were trying to... ah... consult with me... I won't say anything anymore... So please...!"
It seemed she had finally realized that regardless of whether the files were posted to the group chat, her daughters were bound to see her in that humiliating state.
"Please what? What do you want me to do? You have to speak clearly for me to understand! Seon-mi!"
Si-woo called her by her name, mocking her.
"Haa-ah... Please come pick me up! M... Master... I can't go home alone like this... ngh... ah!"
In her frantic state, she mixed formal and informal speech, pleading with him through sobs.
"Why can't you come home alone? It's not like you're tied up like Gyu-ri was! Just find something nearby to throw over yourself and run for it! Why are you whining, you fucking bitch?"
Si-woo spat out the insults, berating her harshly.
"Mom... being like this... hngh... is really hard... uuugh... ngh..."
Her voice sounded like she was about to break down in tears.
Yet, even then, she didn't seem to have any intention of removing the vibrator pressed against her clitoris.
Si-woo found her state and her desperate voice absolutely adorable.
"Se-young and Su-a did far worse than this without a single word of complaint. Why are you whining so much just because I stripped you where no one can see? You total slut!"
Si-woo looked down on her, comparing her to the younger girls and hurling verbal abuse.
After speaking, he opened the gallery app on his phone and looked for the photos and videos of Se-young he had taken today.
He began uploading photos and videos of Se-young and Su-a—things he hadn't shown his mother or the rest of the family yet—into the 1:1 chat window with his mother.
Photos of his sisters naked inside the dark haunted house.
The provocative exhibitionism play they did while walking from the call van to Aunt Seon-ju’s house.
And the photos and videos of the humiliating outdoor urination play he did with Se-young behind the park bathroom.
Si-woo uploaded all the exhibitionism play files of Se-young and Su-a from today into the 1:1 chat room as if he were showing off.
The videos and photos of the younger girls were clearly much more extreme than what his mother was currently doing.
The numbers next to the thumbnails in the chat window disappeared instantly.
It seemed his mother was checking the files her son had sent.
[See? Se-young and Su-a don't whine like you do when they're doing stuff like this!]
Si-woo messaged her again.
"Haa... hngh... ahhh... ngh... haa-ah...!"
Instead of a reply, all he could hear was his mother’s heavy, sobbing breath.
Had she reached an orgasm from seeing her daughters' exhibitionism?
Or did the fact that Se-young had already performed even more humiliating acts with Si-woo excite her even further?
Si-woo switched back to the vibrator app and lowered the intensity to the lowest setting.
As the level on the screen dropped, the violent rattling of his phone subsided.

Si-woo spent some time listening to his mother’s heavy breathing, as if giving her time to recover.
"Mom~?"
After a while, Si-woo called out to her in a calm, friendly tone.
"Haa... haa... What!?"
His mother answered, still catching her breath.
She sounded slightly irritable, displeased with how Si-woo could switch from berating her with foul language to calling her so affectionately.
"I'll come over there now, just like you wanted. But in exchange, you have to do one favor for me."
Si-woo took the opportunity to present his planned terms of the deal.
"Phew... W-what favor? Tell me."
At the news that Si-woo was coming back to her room, his mother responded eagerly, as if grabbing onto a lifeline in her desperation.
