Chapter 209
"Haaaah...!"
Se-hee Noona stared at Si-woo for a long time before letting out a heavy sigh that sounded more like a groan of despair.
"What? Is... is there a problem? Was I too much just now?"
Si-woo asked, looking slightly flustered as he watched Se-hee Noona sigh right after his serious declaration.
"It’s not that... It’s just, now that things have turned out like this between us, doesn't it mean I can't ever see another man for the rest of my life?"
Se-hee Noona spoke to Si-woo as if complaining, feeling the unfairness of it all as the reality sank in.
"Of course! Se-hee, you're mine now!"
Si-woo answered firmly.
"Sigh... Si-woo, you're planning to have Mom, Se-young, and Shin-bi all for yourself! But you're saying I have to live the rest of my life knowing only you?! How is that fair?!"
Se-hee Noona sighed again, her tone bordering on a pout.
"Hehe... It can't be helped. Things are already the way they are! Instead, I'll let it slide if you do things with other girls."
Si-woo gave a sly grin, answering her playfully.
"What?!"
Se-hee Noona reacted as if his answer was utterly absurd.
"I'm saying you can keep seeing Shin-bi. And if you're interested, you can even seduce Mom or Se-young and eat them up yourself. Hehe."
Si-woo grinned mischievously once more.
"What... what are you even saying?!"
Startled by his words, Se-hee Noona’s usual way of speaking slipped out.
"Haaaaah..."
Then, as if realizing the reality of her situation again, she let out another deep sigh.
"Don't worry! I'll protect you and our family with my life! And I'll make sure you experience everything other men could never give you!"
Si-woo spoke as if making a vow, tightening his grip on Se-hee Noona’s hand.
Triumphantly, he nudged aside the jacket draped over his arm, thrusting his rock-hard, erect penis forward so only Se-hee Noona could see it.
Se-hee Noona had been looking at his face, but her gaze instinctively drifted downward.
Beneath the navy suit jacket hanging from Si-woo’s arm, his massive, erect cock came into her view.
Whatever she imagined, her face instantly flushed red, and she quickly turned her head away.
For the next two stops, Se-hee Noona stood there in silence, holding Si-woo’s hand.
Then, she blurted out a remark as if it had just slipped from her lips.
"If you let me get fat, you're dead!"
Se-hee Noona gave this final warning to her younger brother, Si-woo, as his older sister.
Si-woo suppressed the sudden urge to shove his cock shaft deep inside Se-hee Noona right then and there.
Hand in hand, Si-woo and Se-hee Noona remained on the subway train as it sped toward home.
* * *
Si-woo and Se-hee Noona arrived at the station near their house.
The two stepped out of the subway station and began walking straight home.
The hands they had joined on the train remained tightly clasped, never letting go.
When they reached the public restroom in front of the park near their house, Se-hee Noona stopped walking.
"Why? Do you need to pee?"
Si-woo, who had been walking hand-in-hand with her, stopped as well and asked.
Se-hee Noona silently shook her head.
"Then why?"
Si-woo studied her expression, worried about her condition.
With an embarrassed look, Se-hee Noona glanced toward Si-woo’s crotch.
Where her gaze landed, Si-woo’s lower half was bulging massively, standing so tall it looked ready to burst through his pants.
It seemed Se-hee Noona was worried about the awkward situation they’d face if they went home like this and ran into Mom.
"You want me to take care of it first?"
Si-woo asked casually, understanding her concern.
"Sigh..."
Se-hee Noona didn't look at him; she just blushed, sighed, and nodded.
Even though they had already done so much, Se-hee Noona still seemed embarrassed to mention such things directly to Si-woo.
Furthermore, ever since her final warning on the subway, she seemed to be having a moment of self-reflection, making her feel quite shy about speaking out loud.
"Then take off your panties. I saw earlier that they were soaked through from the leaks."
Si-woo now spoke of her taking off her underwear as if it were the most natural thing in the world.
Se-hee Noona couldn't meet his eyes.
She simply nodded, released his hand, and turned toward the women's restroom as if trying to escape.
"Ah, wait! No need for that. We can just go in together this time!"
Si-woo spoke firmly, grabbing the wrist of Se-hee Noona as she tried to head for the women's room.
"Wh-what?"
Startled by the grip on her wrist, Se-hee Noona turned back to him.
"Why go back and forth? Let's just finish it all at once!"
Si-woo pulled her by the wrist and led her into the men's restroom.
"Wait... wait a minute! What are you doing?!"
Though she protested in surprise, Se-hee Noona followed him into the men's room without much resistance as he pulled her along.
Inside the men's room, Si-woo entered an empty stall with Se-hee Noona, closed the toilet seat cover, and sat down on it.
He immediately pulled down his pants and underwear, releasing his erect genitals.
Si-woo’s iron pillar, standing tall and straight, revealed itself to Se-hee Noona once again.
"Kneel on the floor!"
Si-woo’s command was firm.
After a moment's hesitation, Se-hee Noona obeyed his order, kneeling on the bare restroom floor and settling in front of him.
"Suck it!"
Si-woo commanded her with a single word, offering no further explanation.
With glazed eyes, as if drugged, Se-hee Noona took the entirety of Si-woo’s cock into her mouth.
Slurp, squelch, sluuuurp—
The wet sounds of Se-hee Noona’s mouth filled the stall.
Si-woo placed a hand on top of Se-hee Noona’s head, savoring the sensation of her mouth and tongue against his cock.
Receiving Se-hee Noona’s service in a toilet stall at the park near their house—a place familiar to him since childhood—Si-woo felt an overwhelming sense of triumph.
"Mmm... Ugh... Seon-mi... I'm going to make her just like you, Se-hee. So... don't worry about a thing!"
Si-woo stroked her hair with the hand resting on her head.
In her kneeling position, Se-hee Noona looked up at Si-woo and nodded, her mouth still full of his penis.
"If Seon-mi tries to act like she's going to scold us, I'll just rape her into silence!!"
Sitting on the toilet cover, Si-woo thrust his hips back and forth, boasting of his natural physical prowess as he spoke to her.
As if she understood, Se-hee Noona maintained eye contact with Si-woo while increasing the suction in her mouth, moving her head in rhythm with his thrusts.
Soon, an intense, violent urge to ejaculate surged through him.
—Spurt! Spurt! Spurt!!
While maintaining eye contact with Se-hee Noona, Si-woo vomited his semen into her mouth.
Gulp, gulp, gulp!
As if it were now second nature, Se-hee Noona swallowed the semen Si-woo had ejaculated into her mouth.
* * *
Mom was currently back at the house.
After being away for about a week, she had returned and was waiting for Si-woo and Se-hee Noona.
The last text message Mom had sent to Se-hee Noona...
It told her to bring Si-woo home as soon as they woke up in the morning.
It was a threatening message, warning that there would be hell to pay if they were late.
It seemed Mom had reverted to the version of herself from before she had sex with Si-woo.
Mom was setting the mood as if Se-hee Noona didn't know about the fact that she had slept with Si-woo, or that they had agreed to a master-slave relationship over text.
Si-woo also checked the messages sent to his own smartphone from Mom.
[Where are you guys?], [You're with Se-hee, right?], [I told you to make sure to use contraception!], [What are you really planning to do?], [Mom and Se-young are waiting at home, so come back quickly!]
After Si-woo ignored her first text, a string of messages had followed on his phone.
Mom had indeed bombarded him with texts when he ignored her, just as she had with Se-hee Noona.
However, there was clearly a significant difference compared to the messages sent to Se-hee Noona.
There was a distinct difference in "temperature" between the texts Mom sent to Se-hee Noona and those sent to Si-woo.
That difference in temperature was enough to make Si-woo’s heart flutter with excitement.
Perhaps Mom was sending these mischievous signals of submission and sexual playfulness while pretending not to?
Even if that wasn't the case, Si-woo drew great comfort and confidence from the fact that Mom’s attitude toward him was considerably more cautious than her attitude toward Se-hee Noona.
As they drew closer to the house, a mixture of sweet anxiety and tightening excitement swirled in Si-woo’s chest.

Finally, Si-woo and Se-hee Noona arrived home.
The two opened the front door and stepped inside to meet Mom.
