Chapter 278 (Mom)

Even though he’d taken a hard hit to the head with a ladle, Si-woo felt a surge of pride at the fact that he had become someone capable of shaking his mother’s emotions to such an extent.
Given his mother’s personality, Si-woo wondered if she was exaggerating her anger and putting on an act even though she wasn't actually that mad.
"I never had a chance to talk~ You just went and fainted on your own before I could say a word, haha. Se-hee and Seon-ju both held out just fine... but you're the only one like this, Mom. Don't you think you really need to start exercising?"
Si-woo spoke, teasing his mother once again.
"I told you Mom is angry, and you're still going to keep teasing me like that?! Si-woo, if you keep this up, Mom might really take Se-young and just leave this house for good!!"
As if she truly disliked Si-woo teasing her, Mom threatened him with a menacing sentence intended to shut him down.
"Alright, alright~ I'll stop teasing you now, haha. This house belongs to you, Mom, so why would you leave?"
To calm her down, Si-woo spoke soothingly, matching her mood.
Was it maternal instinct or carnal desire? Which was her true nature?
At this point, it was difficult to even distinguish what was play and what was acting.
Si-woo’s cock was swollen red as if it might burst at any moment, twitching as if it wanted to pierce through the ceiling of the changing room.

"Mom~ Did you happen to come into my room at dawn and clean up the mess?"
Si-woo asked as if to confirm, remembering how the traces of masturbation and ejaculation he’d left right before falling asleep had been wiped clean by the time he woke up.
"Where would Mom find the energy to go into your room at dawn?! I was already overwhelmed checking Se-young’s smartphone, and it’s driving me crazy knowing Se-young was in Se-hee’s room with all her clothes off doing that with you guys!!"
Contrary to Si-woo’s expectations, Mom replied that she hadn't had the luxury of tidying his room.
Si-woo had brought it up intending to praise her as her master for her actions instead of teasing her.
He tilted his head slightly at his mother’s unexpected answer.
If it wasn't Mom, then it meant Se-hee Noona had woken up at dawn, entered his room, and cleaned it...
Se-hee Noona wasn't usually the type of person who was meticulous about tidying up or cleaning.
She certainly wasn't the type to wake up at dawn and clean not just her own room, but Si-woo’s as well.
Si-woo felt a considerable sense of awkwardness regarding his mother’s answer and the actions Se-hee Noona would have taken at dawn.
However, regardless of her usual behavior, there was no law saying Se-hee Noona couldn't clean Si-woo’s room.
Perhaps since deciding to enter a master-slave relationship with Si-woo, a sense of awareness and responsibility as a slave had blossomed within Se-hee Noona.
"Did Se-hee get up at dawn and clean my room while I was sleeping?"
Si-woo muttered to himself as if accepting his mother’s words for what they were.
"Just what kind of mess did you leave that Se-hee would go and clean your whole room at dawn?"
Mom, also curious that the same Se-hee who didn't even clean her own room properly had cleaned Si-woo’s, asked him back.
"Ah... actually, I masturbated on my bed before I went to sleep~ I’m pretty sure I just fell asleep right after I came, but when I woke up, it was all cleaned up~"
"So I just assumed Mom had come into my room to tidy up while you were on your way to wake Se-young up~"
Si-woo explained the situation he found himself in upon waking, honestly confessing his act of masturbation to his mother.
"Sigh... You came that much yesterday, and you still have energy left?"
Mom scolded him as if she were fed up with Si-woo’s stamina.
"It’s not a matter of stamina, it’s because you’re so pretty, Mom! What am I supposed to do when I get an erection just by thinking about your face and body?"
Despite his mother’s scolding, Si-woo replied shamelessly, using her as his excuse.
"What is this boy even saying?! You keep saying such strange things!"
Mom reacted with a stern face to Si-woo’s playful words, but she didn't seem to be in a particularly bad mood.
"It’s true~ When I think about how I can make you eat my semen every day from now on, it stands right back up!"
Si-woo tried some slightly high-level dirty talk on his mother.
"Goodness!! Just hurry up and finish so you can wash! Are you going to be like that all day?!"
This time, Mom didn't get angry at Si-woo’s provocative comment; instead, she hurriedly ended the conversation as if embarrassed.
"Got it~ Haha. I’m going to cum right into Se-young’s panties now, haha."
Si-woo replied to his mother, feeling a strange sense of pride.
Until not long ago, Si-woo would never have imagined he could naturally share such lewd and obscene conversations with his mother.
And to do so while directly informing her that he was masturbating in real-time...
Even though he’d been hit hard on the head with a ladle and threatened with her taking Se-young and leaving the house...
Si-woo knew for certain from his experiences so far.
No matter what she said or what kind of detestable act she put on while wearing the mask of a mother,
It was a fact that his mother’s true nature was that of a female slave in heat, enjoying being insulted and violated even by her young son...
In any case, it seemed that as long as it wasn't a prank directly related to Se-young or Se-hee Noona, Mom was now accepting even Si-woo’s sexual jokes.
Si-woo spread Se-young’s panties, which had been wrapped around his penis, onto the floor in the center of the changing room.
Then, kneeling and leaning his body forward, he tilted the head of his penis toward Se-young’s panties.
Slap! Slap! Slap! Slap! Slap!
Si-woo gripped his penis with his bare hand and began to shake it rapidly.
Se-young’s beginning-to-swell breasts... her cute, protruding pink nipples.
And due to the lewd conversation he’d just exchanged with his mother, Si-woo’s body was already heated to the point of being right on the verge of climax.
Splurt! Splurt! Splu-urt!
The white liquid erupted from Si-woo’s penis like lava from a volcano, pouring onto Se-young’s panties spread on the changing room floor.
Si-woo’s thick, hot liquid was sprayed across the floor, covering almost all of Se-young’s panties.
Without even taking a moment to catch his breath, he picked up his smartphone to capture the traces of his ejaculation.
Click! Click! Click!
Se-young’s panties, drenched in Si-woo’s semen, were captured on his smartphone.
Without a moment’s hesitation, Si-woo sent the photo of Se-young’s panties to his mother.
The numbers next to the photo in the chat window disappeared in real-time.
Inside the changing room, Si-woo’s male scent, seemingly intended to seduce his mother, drifted like bait in a snare.
* * *
Without even cleaning the floor, Si-woo went straight into the shower room.
He placed the smartphone he’d brought with him onto the shelf where the towels were kept.
After turning on the water and waiting a moment, warm water began to pour from the showerhead.
Shhhhhhh~
After ejaculating, Si-woo soaked his body under the pleasant stream of the warm shower.
After thoroughly wetting himself, Si-woo turned off the shower faucet.
He squeezed some shampoo into his palm and rubbed it into his hair to create a lather.
Then, he applied body wash to a shower towel, worked up a lather, and scrubbed every corner of his body.
Before long, he sensed someone entering the changing room.
It felt as if he could faintly hear the small bell attached to Mom’s red leather dog collar even inside the shower room.
Mom’s silhouette was visible through the opaque glass door of the shower.
Mom let out a long sigh, then knelt down and began to clean up the traces of ejaculation Si-woo had left behind.
The sight of his mother cleaning the floor and the panties of Se-young that he had defiled...
As that strangely erotic image of his mother was reflected through the opaque shower door, Si-woo’s cock began to stand tall and hard once again.
Seeing his mother like that, Si-woo gripped his penis, which was slippery with foam, and began to shake it up and down.
Squelch! Squelch! Slap! Slap! Slap! Slap!
The sound of flesh rubbing against foam and the sound of impact echoed simultaneously inside the shower room like a cave.
Mom, who had been cleaning the floor, stopped and lifted her head as if reacting to the sound, her body trembling in surprise.
Mom was undoubtedly looking at the silhouette of Si-woo masturbating through the shower door.
Si-woo turned the shower back on and rinsed the foam from his hands.
He picked up the smartphone he’d placed on the shelf for his mother and took a photo of his erect cock.
Click! Click! Click!
Si-woo sent the photo of his massively swollen penis inside the shower room to his mother.
Ding! Ding! Ding!
The message notification sounded on Mom’s smartphone.
Mom stopped what she was doing and checked her phone for a moment.
Si-woo moved closer to the semi-transparent glass door of the shower while continuing to masturbate, so that the silhouette of his body and the shape of his penis would be even more visible to her.
Mom seemed frozen, looking back and forth between her smartphone screen and Si-woo’s figure reflected on the glass door, like a beast caught in a trap.
