Chapter 417 (Mom)

[See? Even if it was hard at first because it was so big, once you tasted it a few times and adjusted, you feel like you can't live without our Master's cock now, right?]
[I’ve always known how much of a prude you are, Unnie~ I didn't think Master would make you submit this quickly, though~ As expected, our Master is truly amazing!]
[Master, please take good care of my Unnie from now on~ But don't neglect me too much because of her. You know I'm Slave No. 1, right?]
Aunt Seon-ju spoke to Si-woo in a playful, teasing tone.
[Unnie loves the position where she gets her ass slapped while doing it from behind, so please do that often! LOL]
[She also loves it so much she practically faints when she's being fucked while having her nipples, anal, and clitoris all sucked at the same time, so definitely try that when you get the chance!]
Aunt Seon-ju continued to pour out lewd and suggestive comments, using Mom as her subject.
[I'll take the anal, Se-young and Su-a can each suck a nipple, and Se-hee can lick the clitoris. Unnie also loves nursing while being fucked, so maybe we can ask Se-jin to let her breastfeed?]
As if she had found a new hobby in teasing Mom, Aunt Seon-ju continued her provocative dirty talk, listing the family members' names one by one.
[Seon-ju, shut up! That's enough, so just stop it already!]
Perhaps finding Aunt Seon-ju’s messages—which exposed her preferences in front of the family—too embarrassing, Mom cut her off with a sharp tone.
[Oh my~! Unnie, are you actually speaking here now? I thought you’d decided to stay silent since you only barely answered when Master forced you to~]
[Now that you've finally opened your mouth, we can just have family meetings here~ Let's see each other often, Unnie! LOL]
Aunt Seon-ju maintained her teasing attitude, yet she spoke as if she were genuinely glad and proud of Mom's change.
[See each other often? For what! I told you to stop, you really don't know when to quit!]
[When you think about it, this is all your fault! You and Gyu-ri planned to make things like this from the start, didn't you?!]
Mom snapped back, seemingly provoked by Aunt Seon-ju’s continuous teasing and goading.
[Oh my~? Do you think we're like you, Unnie? Things just took their natural course. What did Gyu-ri Unnie and I even do? Someone might actually get the wrong idea if they heard you!]
[Master~! Look at her trying to pick a fight with us because she's embarrassed, even though she did everything she wanted to do because she enjoyed it~! Since she made her Slave Declaration today anyway, please discipline her until she cries so she can fix that bad habit of hers! LOL]
Aunt Seon-ju reported to Si-woo like a younger sibling tattling to a parent about a petty squabble, pointing out the other's flaws or mistakes.
[Are you going to keep acting like this? Seon-ju, you'd better watch out when I see you! I have a lot to say to you!]
Mom expressed her strong dissatisfaction, her tone suggesting she was ready to confront Aunt Seon-ju in person.
[Heehee~ Master~ Unnie is being scary and telling me to watch out~ Please protect me so she can't hurt me~!]
Aunt Seon-ju acted coy and played the victim to Si-woo.
[Alright, alright~! Both of you, that's enough! Seon-ju, stop teasing Seon-mi now!]
Si-woo stepped in to restrain Aunt Seon-ju, perhaps feeling a bit sorry for Mom, who was being relentlessly teased.
[Yes~! Master! Since you said so, I'll stop teasing her now~! LOL]
As soon as Si-woo spoke, Aunt Seon-ju’s flirtatious reply came back immediately.
[...]
Then came Mom's message.
Perhaps too embarrassed and ashamed to answer Si-woo directly, Mom tried to substitute her answer with an ellipsis, as if to indicate she understood.
[Seon-mi, you fucking bitch. Is that how you're supposed to answer when your Master is talking? Answer me properly.]
Si-woo demanded a proper response, hurling a curse at Mom for trying to gloss over the situation with dots.
[I'm sorry, Master. I'll stop now, too.]
After a brief moment of hesitation, Mom answered Si-woo in her capacity as a slave.
[LOL]
Aunt Seon-ju’s laughter followed, mocking Mom's predicament.
[Se-hee, Se-young, and Su-a—if you've all checked the video content, answer here right now!]
Si-woo demanded a response from Se-hee Noona and Se-young as well, who must have been watching Mom's Slave Declaration, the photos, the videos, and the entire conversation in the group chat.
[I just checked it, Master. When I'm with Mom, I just have to do what you said in the video, right? That we should always be completely naked, even without underwear, when we're on the second floor...]
Se-hee Noona, who had checked the video first, sent her reply.
[I saw the video, Master. I'll keep that in mind for now.]
Next came Su-a's message.
[I checked it too! Hehe~ Master!]
And then Se-young's message, still appearing a bit awkward and shy, appeared on the screen following Se-hee Noona's.
Only then did Si-woo feel as though all the women in the chat room had become his complete possessions.
A sense of proud achievement and a surging pleasure filled Si-woo’s chest with overwhelming emotion.
* * *
After finishing the conversation in the group chat, Si-woo realized the call with Mom had remained connected the entire time they were texting.
"I'm coming now. Wait for me."
Si-woo spoke into the smartphone's microphone in a low voice.
"Yes? Yes...! Master... I... I'll be waiting."
Mom hesitated for a moment before responding to Si-woo's words.
She still seemed confused, caught between her roles as a slave and a mother depending on Si-woo's whims.
However, Mom seemed to be trying very hard to adapt to being treated as a slave by Si-woo.
Satisfied with Mom's answer, Si-woo ended the call.
While texting and talking in the bathroom, Si-woo had been holding Se-hee Noona's T-shirt the whole time.
The apricot-colored long T-shirt still seemed to hold Mom's warmth and scent.
Si-woo used the bunched-up T-shirt to wipe the shaft and the tip of his glans, which was still erect and outside his clothes.
Mom's apricot T-shirt became soiled as it wiped away the fluids smeared on his shaft and glans.
After a brief moment of thought, Si-woo tossed the T-shirt straight into the bathroom trash can.
What kind of expression would Mom make when she realized she no longer had any clothes to wear on the way home?
Si-woo tucked his penis back into his clothes, straightened himself up, and left the bathroom.
He walked back through the karaoke hallway, slowly heading toward the room where Mom was.
As he passed through the corridor, the echoed singing of female students drifted from all directions, sounding surreal.
Before long, Si-woo arrived in front of the coin-operated room in the corner where Mom was waiting.
Just as Si-woo had expected, the door to the room remained halfway open.
Rather than choosing the simple and easy option to lessen her shame, Mom had chosen the masochistic pleasure of a slave that came from obeying Si-woo's command.
Si-woo pushed the half-open door and entered the room.
In the corner of the room, he saw Mom's naked body, huddled up and clutching the shopping basket.
Mom flinched as she looked at Si-woo entering the room, her eyes brimming with tears that looked ready to spill over at any moment.
Her current appearance was a stark contrast to the way she had been bickering and arguing with Aunt Seon-ju in the group chat just moments ago.
Now, Mom was simply a helpless and miserable woman.
She was a woman who had been stripped naked in a public place by a son much younger than herself, unable to offer any real resistance.
Perhaps clutching that shopping basket was her last shred of resistance, a desperate attempt to protect what remained of her shattered pride.
The vibrator was still buzzing with a low vibration.
Si-woo turned around and closed the open door.
With the click of the door closing, the sounds of the bustling singing and accompaniment from outside faded.
Si-woo walked over and sat down next to Mom.
She was clutching the shopping basket, which was far too small to cover her body.
She sat with her upper body hunched forward, her eyes cast down in shame, her body trembling.
Mom's breasts, crushed by her arms and the shopping basket, bulged out to the sides like thick, viscous mounds of flesh.
Si-woo gently placed his hand on one of those breasts.
The soft, elastic, and pleasant flesh met Si-woo's palm.
Mom's body jolted, and a ragged breath escaped her lips.
"Mom?"
Si-woo called out to her gently in a low voice, stroking the side of her protruding breast.
"Uh, ugh... Yes?"
Mom reacted with slight confusion when Si-woo addressed her as 'Mom,' as she had expected him to treat her like a slave and speak down to her the moment he entered the room.
