Chapter 289 (Mom, Se-hee, Se-young)

"But Si-woo Oppa! Why did you leave me in Se-hee Unnie's room yesterday instead of mine?"
While Mom went into the master bedroom to get Se-young's smartphone, Se-young watched Si-woo approach the electric pressure rice cooker with curious eyes and asked.
"Ah~ You said you sleep well even when you're suckling Aunt Seon-ju's breast, so I wondered if Se-hee could do it too. You said you sometimes wake up at dawn and go back to Mom's room to sleep, right? Mom is tired, so if you and Se-hee take turns sleeping with her on set days, wouldn't that make her a little less exhausted?"
Si-woo answered Se-young's question as if it were no big deal.
—While subtly pretending to care for Mom, he was actually suggesting she take turns sleeping with Se-hee Noona.—
"Hehe~ I mean, I like sleeping with Noona too..."
Se-young spoke with a regretful expression, looking at Se-hee Noona, who had supposedly overslept because she let Se-young nurse last night.
"It seems like she struggled a bit since it was the first time, but well... Se-hee said she didn't mind letting Se-young nurse while she sleeps. It'll get better once you get used to it. Right, Se-hee?"
Si-woo asked in a subtle tone, as if forcing an answer out of Se-hee Noona.
"Ye... yes... once I get used to it..."
Se-hee Noona, sitting at the dining table, answered Si-woo's question reluctantly.
Si-woo glanced toward Se-hee Noona.
Her breasts were packed so tightly under her white hoodie that they looked ready to burst. In the center of those breasts, prominent protrusions stood out, their outlines clearly visible.

—Ding!
A text message arrived for Si-woo as he was scooping rice from the electric pressure rice cooker into bowls.
It was a message from Mom, who was in the master bedroom.
[Did you delete it?]
It was a brief message from Mom, omitting both the subject and the object.
[What?]
Si-woo had a good idea of what Mom was asking, but he intentionally played dumb and replied to her short text.
[What do you mean 'what'?! Si-woo! Did you delete that video of me you sent to Se-young earlier?!]
Slightly annoyed by Si-woo's feigned ignorance, Mom sent a complete sentence this time to confirm.
It seemed Mom wanted to check if the lewd video of her sent to Se-young's smartphone had been deleted before she returned the phone to Se-young as Si-woo had instructed.
[What video~?]
Si-woo continued to respond nonchalantly, acting as if he had no idea what she was talking about.
[Are you going to keep playing dumb? The video we took in the changing room!!!]
Mom sent the message with three exclamation marks, expressing her frustration at Si-woo's teasing.
[Ah~ are you talking about this? The one where Mom gets slapped on the cheeks by my cock? You have to be specific for me to know! lol]
After sending that message to tease her, Si-woo immediately found the video of Mom he had taken in the changing room and uploaded it to the chat window.
Mom's humiliating appearance, with Se-young's panties pulled over her head while her cheeks were being struck by Si-woo's penis.
The shameful video, capturing Mom accepting Si-woo's actions with a flushed face, was sent to her.
There was no reply for a moment, as if Mom was checking the video Si-woo had sent.
[Why are you sending this here?!! I have to give the smartphone back to Se-young right now, so just tell me if you deleted it already!]
Mom flared up in embarrassment, demanding an answer regarding whether the video he sent to Se-young had been deleted.
[Haha~ Well, I told you to give it back to Se-young because I've sorted everything out~ haha]
As if to reassure Mom, Si-woo gave an ambiguous answer, saying he had "sorted it out" instead of saying he had "deleted it."
Si-woo felt there was no longer any reason to hide the sexual secrets or the relationships with other family members from Se-young.
Without deleting the disgraceful video of Mom he had uploaded to the chat window with Se-young, Si-woo intended to let Mom return the smartphone to her.
[Check again just in case to make sure it's properly deleted!]
Just to be safe, Mom urged Si-woo once more to confirm the video's deletion.
[Don't worry~ I took care of everything while you were showering!]
Si-woo intended to deceive Mom until the very end.
What kind of expression would Mom make when she later realized the photo hadn't been deleted after giving the smartphone back to Se-young?
Si-woo imagined Mom's face, devastated and in shock, her heart sinking.
As he imagined her miserable state, Si-woo's cock throbbed and twitched inside his clothes.
* * *
Si-woo sat down at the table after placing the rice bowls he and Se-young had filled in front of the family.
He nonchalantly observed the expression of Se-young, who was sitting across from him.
Se-young still had a bright expression, as if she knew nothing.
Even though she had seen her brother's erect penis covered with a condom...
Even though she had seen that long, magnificent rod being shaken up and down...
Se-young treated Si-woo just like usual, without showing any particular sign of it.
Si-woo recalled the time he had intentionally shown his erect state in his underwear to Se-young when she came into his room to wake him up the other morning.
Se-young had whispered "You perverted piece of shit" into the ear of Si-woo, who was pretending to be asleep, her voice laced with contempt.
When Si-woo had gotten out of bed and gone downstairs feeling awkward, Se-young had spoken to him as if nothing had happened.
Just as Si-woo had invited Mom into a game of deceit, mocking her by acting differently between day and night...
He felt that now, he could reveal the whole truth to Se-young.
* * *
Before long, Mom came out of the master bedroom with Se-young's smartphone.
Mom clutched the smartphone tightly with both hands and held it to her chest as if trying to calm herself.
She glanced toward where Si-woo was sitting, let out a small sigh, and approached Se-young.
"Se-young... here..."
Mom handed the smartphone to Se-young with a reluctant expression.
"Wow~ you really found it? Where was it? I looked in the master bedroom while you were washing earlier, but I couldn't see it."
Se-young took the smartphone with a joyful expression and asked Mom.
"Uh... it was... under the bed... I think it fell there after I brought it in and fell asleep last night..."
Mom avoided Se-young's eyes and gave a vague excuse before sitting down across from Se-hee Noona.
After unlocking the smartphone she received from Mom, Se-young began checking the messages and notifications that had arrived overnight.
Se-young would soon see the video of Mom that Si-woo had sent.
Si-woo was certain that Se-young already realized the relationship between him and Mom, or perhaps even more.
However, the thought of Se-young actually checking the video and secretly sharing that lewd relationship with him made Si-woo's heart start to race.
A strange tension seemed to flow around the kitchen table where Si-woo sat.
If he picked up his smartphone and opened the chat window he shared with Se-young, he could easily see when she checked the video of Mom he had sent.
But Si-woo intentionally didn't look at his phone.
In this messy flow of fate he had surrendered to, he wanted to simply observe and enjoy the fluttering, tightening tension and excitement until the very end...

"Do we not need to feed the puppy we brought yesterday breakfast?"
Si-woo struck up a conversation using the puppy as a topic, gauging Se-young's mood as she looked at her smartphone.
"Se-a is still sleeping~ Hehe~ I'll give it to her when she wakes up~"
Se-young answered Si-woo's words with her usual bright smile.
"We're going to the department store today to buy puppy supplies, right? Feed, a food bowl, and a necklace?"
Si-woo continued to talk as if questioning Se-young, trying to hide his tension and excitement.
When Si-woo glanced toward Mom while mentioning the necklace, Mom flinched as if her body had received a tiny electric shock.
"Yeah~ Hehe~ I'm going to buy a toothbrush, toothpaste, and shampoo too~ We also need potty training pads, a bag for traveling, and a cage~"
Se-young spoke to Si-woo, counting the items on her fingers as if excited by the mention of puppy supplies.
"Didn't you say you were going to buy a dog house too?"
Si-woo asked Se-young, as if checking the list of items they had agreed to buy yesterday.
"I'm going to use the cage as the dog house~ Everyone does it that way these days~ Look!"
Se-young fumbled with her smartphone and held the screen out toward Si-woo.
As she extended her arm, Se-young's areola was exposed outside her clothes.
Si-woo was slightly flustered by Se-young's bold action, occurring in a situation where he didn't know if she had checked the video of Mom he had sent or not.
On the screen was a photo of a large iron dog cage.
"Oh?... Uh... I see... Is that how people do it these days? If it were a bit bigger, you could even lock a person in there."
Si-woo blurted out his honest impression of the photo, imagining Mom lying face down inside the cage.
