Chapter 290 (Mom, Se-hee, Se-young)

"There’s even a cage for large dogs~ Su-a’s family bought one recently. You haven't seen it yet, right? Want me to show you?"
Se-young asked Si-woo, seemingly looking for another photo to show him.
"Really? Let me see."
Si-woo acted curious, waiting for the photo Se-young was about to pull up on her screen.
With her eyes cast down, Se-young busily tapped her smartphone screen, searching through her saved photos.
Si-woo waited, naturally assuming she would thrust the screen toward him to show him.
However, Se-young didn't lift her arm to show him the screen.
—Ding!
Instead, a text message notification rang out from Si-woo’s smartphone.
Without thinking, Si-woo looked down at the phone in his hand.
A notification for a text message from Se-young was displayed on the screen.
"Huh?"
He reflexively tapped the screen to open the chat window.
A photo of a steel cage for large dogs, seemingly taken at Su-a’s house, appeared in the chat.
It was a simple photo of a cage, the kind of mundane thing siblings might normally exchange.
But right above it was the video Si-woo had sent from the changing room, the '1' indicating it had been read now gone.
—A video whose thumbnail showed Mom’s humiliating face, with panties pulled over her head and Si-woo’s cock resting on top of her...—
For a moment, a wave of cognitive dissonance washed over him, and Si-woo froze as if his brain had stalled.
He stared blankly at the text message Se-young had sent for a long time.
"I just sent the photo via text, Si-woo Oppa~"
Se-young spoke as if confirming that the message she just sent was the photo she mentioned.
She looked at Si-woo, who was staring blankly down at his phone, and gave him a bright, innocent smile.
It was an act that was no different from Se-young confirming to Si-woo that she had received the video of Mom.
As Se-young’s innocent, youthful voice rang in his ears, Si-woo felt the blood throughout his body rush toward his penis.
His penis swelled, looking as if it might burst through his pants.
Si-woo stared at Se-young’s face with hollow eyes, finding her expression almost loathsome.
Was it just his imagination, or were the corners of her mouth turned up slightly higher than her usual smile?
A moment later, Si-woo’s body began to tremble slightly, pushed by a sadistic desire.
He barely suppressed the urge to shove the food on the dining table aside, pin Se-young down, and rape her right there.
* * *
"...You’re right. If it’s someone about Mom’s height, two or three people could probably fit inside together."
Si-woo spoke while scrolling up and down the chat window with Se-young, trying to calm his mind.
"Right? I went inside with Su-a, and it was huge! It’s sturdy, too! It even has curtains on the outside, so you can cover it so no one can see inside from the outside~ Hehe~"
Se-young explained the features of the cage to Si-woo boastfully, as if she were enjoying herself.
"I see. It’s really big. This would be perfect for punishing bad people who lie or steal things."
Si-woo spoke as if pointedly calling out Mom’s behavior from that morning.
After speaking, he glanced up at Mom’s face to gauge her reaction.
Mom’s face was flushed deep red, as if she were foreseeing her own fate.
"Oh, right! Se-hee, didn't you say earlier that you had something to give Mom later?"
Si-woo turned to Se-hee Noona beside him, acting as if he had just remembered.
"Huh? Oh... yeah... that’s right. I have... something to give Mom..."
Se-hee Noona responded to Si-woo’s lead, answering exactly as he had instructed her.
Sitting across from Mom, Se-hee Noona’s face was also burning red with embarrassment.
"S-something to give me? What is it?"
Mom asked, looking back and forth between Si-woo and Se-hee Noona with an anxious expression.
"That... well... I’ll tell you separately later, Mom..."
Se-hee Noona stammered her answer, glancing at Se-young as if she were in a difficult position.
"Se-hee Unnie, why tell her separately later? What are you giving Mom? Am I not allowed to know?"
Se-young asked with a disappointed pout, as if she felt left out by Se-hee Noona’s words.
Se-hee Noona was at a loss for words, her face troubled, not knowing how to respond.
"It’s nothing special, Se-young. We’re just talking about a snack to feed Mom after we leave!"
Si-woo kindly explained to Se-young on behalf of the struggling Se-hee Noona.
"Feed Mom? What’s that?"
As if her curiosity was piqued even further by Si-woo’s explanation, Se-young leaned forward, propping her arms on the dining table.
As her one-piece dress shifted against the table, Se-young’s provocative pink nipple was exposed.
"Ah, should I call it a drink? It would be nice if Se-young could have a proper taste of it later, too. Well, maybe Se-young already knows the taste?"
Si-woo spoke to Se-young in a playful tone, as if playing a game of twenty questions, but making sure Mom heard every word.
Mom seemed to realize immediately what Si-woo and Se-hee Noona were planning to give her; she hung her head low, breathing heavily.
"Once Se-hee gives it to you after we leave, drink it immediately. Just take it all and drink it in front of Se-hee. Got it?"
Si-woo spoke to Mom in a soft but solemn tone, as if making a request.
In reality, it was no different from a command.
Mom looked like she wanted to protest, but she simply swallowed hard as if her throat were constricted, answering Si-woo’s command with a silence steeped in resignation.
Se-young looked back and forth between Mom, Se-hee Noona, and Si-woo, tilting her head as if she couldn't understand at all.
Si-woo scrolled all the way down the chat window with Se-young, which he had been idly flicking through.
Then, moving his fingers carefully, he slowly typed a single, short word into the message bar.
'Semen'
To begin a secret conversation with his younger sister, Se-young, Si-woo carefully typed out the answer to the riddle she was curious about.
Looking at the word in the input bar, Si-woo’s heart pounded as if it might explode.
He lifted his gaze toward Se-young and stared, entranced, at her fully exposed nipple.
It was a dainty, pale pink nipple that seemed to be tempting him.
With the feeling of reaching out and violating Se-young’s nipple with his finger, Si-woo swiped the send button on the smartphone chat window.
Perhaps because she already had the chat window open, Se-young’s phone didn't make a separate notification sound.
Se-young simply lowered her head slightly as if checking her phone, then raised it again to look straight at Si-woo.
"I'll let Se-young drink some next time, too!"
After pressing the send button, Si-woo spoke to Se-young while acting composed, gauging the situation.
"Okay~ I’d like that, Si-woo Oppa~ Hehe~"
Se-young answered brightly, meeting Si-woo’s eyes as if his text and the following words were nothing out of the ordinary.
There was no way she hadn't seen it... and no way she hadn't understood...
Si-woo checked the chat window, wondering if Se-young had somehow missed the message he sent.
The number next to the message in the chat window had definitely disappeared.
Se-young was definitely answering after having seen Si-woo’s message.
Si-woo imagined grabbing the collar around Se-young’s neck, staring into her eyes, and ejaculating into her mouth.
Just imagining her submissive gaze and the soft sensation inside her mouth made Si-woo’s chest swell with a sense of fulfillment.
His heart began to throb and race wildly.
* * *
Si-woo switched from the chat with Se-young to the group chat window where Mom, Aunt Seon-ju, and Se-hee Noona were all present.
Then, he prepared to give separate orders to Mom and Se-hee Noona.
[Today while I'm out, Seon-mi, you use formal speech with Se-hee! I left some semen in a condom from when I was with Se-hee this morning! As soon as I leave, ask Se-hee for it and drink it! Se-hee, you film Seon-mi drinking my semen on your smartphone and send it to me immediately!]
After writing the long command, Si-woo pressed the send button without hesitation.
—Ding!
The notification sound rang out from Mom’s and Se-hee Noona’s smartphones almost simultaneously.
The mother and daughter each picked up their phones and checked the message Si-woo had just sent.
Watching the two of them check his command, Si-woo’s cock inside his pants surged with power, feeling as if it might explode.
The air inside the house already felt as if it had ceased to be ordinary.
Mom and Se-hee Noona barely spoke throughout the rest of the meal, perhaps worried about the situation that would unfold once they were left alone after Si-woo and Se-young went out.
Amidst the strangely flowing tension, only the ragged breathing of Mom and Se-hee Noona could be heard, intermingling in a dizzying fashion.
