Chapter 426 (Mom)

While Si-woo headed to the karaoke room's restroom to grab a mop, a text from his mom arrived on his smartphone.
Opening their 1:1 chat window, Si-woo immediately checked the message.
[You’re not just going to leave like this, are you? Where did you hide my clothes? Stop joking around and bring them to me right now!]
It seemed Mom was worried that Si-woo might actually head home without her, just as he had threatened earlier.
[I told you I’m not joking. I really threw your clothes in the restroom trash can! And since we already decided on this, I have no intention of bringing them back for you to wear! lol]
Si-woo emphasized once again that he had discarded her clothes and had no intention of letting her get dressed.
[It’s not even the middle of the night; there are people walking around everywhere! How am I supposed to go home like this?!]
Mom’s text carried a sharp, confrontational tone.
[What? So it’s okay to walk around like that late at night? Then I guess you can just sing until dawn and walk home alone when no one’s around~]
Si-woo replied with a mischievous tone, clearly teasing her.
[Si-woo, are you really going to keep this up even here? Just because I’m playing along with the mood, do I look like some toy you can just treat however you want?!]
Mom reacted with genuine indignation to Si-woo’s persistent teasing, even within the 1:1 chat.
The two of them had agreed to remain in a mother-son relationship specifically within their private chat window.
Yet, only moments ago, she was the one whose core had been pierced by his massive cock, her red, swollen buttocks ruthlessly thrashed.
The female slave who had looked up at him with submissive eyes, cleaning his penis and testicles after his creampie and watersports play, had vanished. In their 1:1 chat, she had returned to being the nagging mother as if nothing had happened.
That strange, jarring gap between reality and the chat window—a dissonance so sharp it was hard to distinguish between the two—made Si-woo feel a peculiar sense of thrill and an alien sort of excitement.
[Hahaha, check the shopping bag~ There’s something in there for you to wear instead of your clothes!]
Seeing her reaction, Si-woo sent a text with a bashful laugh emoji, telling her to open the shopping bag containing the swimsuit.
* * *
Si-woo had brought that swimsuit along when his mom called him, secretly hoping they might end up having sex in a motel or somewhere similar.
Originally, he had intended to make her wear it during a family trip or an outing to humiliate her.
It was the red micro bikini swimsuit he had purchased separately while visiting the department store with his younger sisters.
[Did you check what’s inside the bag?]
Having reached the restroom, Si-woo texted her.
[What is this?]
Mom asked, curious about the item in the bag Si-woo had left on the karaoke room floor.
[It’s a gift~ Se-young, Su-a, and I picked it out for you at the department store today! I wanted you to wear it when we go to a pension this summer!]
[I even sent a photo of Se-young holding it earlier, didn’t I? You should have gotten a text about the card transaction too. Did you miss it?]
Si-woo explained the contents of the shopping bag in detail.
[Is this... that?]
Mom asked, seemingly having confirmed the item immediately.
The swimsuit Si-woo bought for her was a micro bikini.
While such styles were supposedly trendy among young people, they were mostly worn for SNS photos or in private spaces.
Even if it wasn't a "total" micro-mini, the level of exposure was far too high to be worn in front of family.
[Yeah, try it on! I bought it to fit your size. Even Se-young said it would look great on you the moment she saw it!]
Si-woo spoke coaxingly, trying to persuade her to put on the erotic swimsuit.
Being naked, she didn't exactly have a choice.
[You could have given this to me at home; why bring it here? You planned this from the start, didn't you?!]
Mom texted back grumpily, as if complaining about Si-woo’s perverted tastes even though she had no choice but to wear it.
[Aren't you glad you at least have that? Thanks to that, you don't have to wait until dawn~ lol]
Si-woo replied playfully, feigning innocence.
[-_-^]
Seeing Si-woo’s text—which didn't sound like a joke at all—Mom sent her signature emoticon, one that seemed to contain a whirlwind of emotions.
Seeing her return to her usual self, Si-woo felt a pleasant fluttering in his chest.
There was no reply for a moment, likely as she pulled the swimsuit out of the bag to put it on, before she texted again.
[Is this really the right size? It feels a bit tight. And isn't there way too little fabric? Everyone’s going to stare! You want me to go home like this?]
Mom was already sharing her thoughts on the red micro bikini as if she had it on.
She whined to Si-woo for quite a while, sounding almost cute in her complaints.
[It’s probably a bit smaller than a regular swimsuit. But I told you, this is what’s trendy on SNS and private streaming channels these days!]
[Celebrities and influencers wear stuff like this and take tons of photos when they go to pensions or hot springs. I saw it at the department store on the way back and just had to get it! It’s a micro bikini!]
Si-woo continued to coax and persuade her, trying to make the erotic swimsuit feel like something familiar and acceptable.
[Trends don't matter! How am I supposed to go home in something like this?! You dummy!]
Mom finally snapped, scolding him in annoyance.
The undeniable fact that the person scolding him in the chat was the same woman who, just moments ago, had been panting humiliatingly while being impaled by his penis seemed to heighten Si-woo’s arousal even further.
Si-woo switched the screen from the 1:1 chat to the vibrator control application.
Then, with a touch of his finger, he cranked the vibration intensity up two or three levels.
Bzzzzzzzzzt!
The smartphone’s vibration became much more violent than before.
The vibrator in Mom’s groin would be buzzing just like his phone.
Was this a punishment for the insolence she displayed in the chat?
Or was it a display of his superior position, proving he could assert their master-slave relationship at any time, regardless of their conversation in the 1:1 window?
[I’m going to bring the mop and wet wipes now, so just wait there for a second~]
Si-woo switched back to the chat, brushing off her annoyance, and grabbed a mop from the restroom’s cleaning closet.
[Sighhhhh...]
Mom expressed her lamentation with a long, texted sigh.
* * *
Holding the mop, Si-woo left the restroom and headed toward the main hall of the karaoke bar.
In the main hall, there was a vending machine for sanitary products.
Si-woo tapped his mom’s card on the machine and pressed the button to buy wet wipes.
Thump!
The sound of the thick pack of wet wipes dropping into the dispenser echoed impressively.
Before retrieving the wipes, Si-woo re-read the texts he had just exchanged with his mom.
Even though she was currently losing her temper and scolding him in the chat...
Even if it was within the 1:1 chat where they agreed to remain mother and son, she was the woman who had made a humiliating slave declaration in front of the whole family in the group chat.
Furthermore, wasn't she the one who had just been panting while her buttocks were thrashed as he drove into her?
Seeing her show such an extreme shift in attitude made Si-woo feel a strange mix of arousal and indignation.
That feeling of indignation toward her was mostly converted into fuel for his sadistic lust and excitement.
Using her insolence as an excuse for punishment, Si-woo wondered if he could demand a new perverted act from her.
[But Mom, you definitely turned your head earlier, didn't you?]
Si-woo spoke to her, reviving the conversation that had seemingly ended with her sighs and annoyance.
[Turned my head? What are you talking about?]
Mom asked back, sounding confused by his sudden question.
[I mean when we were doing it in the room earlier. When I put the microphone right in front of your face!]
Si-woo spoke as if to remind her of their actions and words in the room.
[The microphone was picking up every sound! Of course! In that situation, how could I not turn my head?! Did you want everyone outside to hear?]
Mom protested indignantly, defending herself against Si-woo’s accusation.
