Chapter 297 (Mom, Se-hee, Se-young)

Above Se-young’s knees, her fair-skinned thighs peeked out from under her skirt as she moved.
"Oh... you look pretty! I think it really suits you, Se-young!"
Si-woo scanned Se-young’s body from head to toe as he answered her question.
"Right? Hehe~ I like it too~"
Se-young was acting as if she had chosen everything herself—the light blue skirt, the orange socks, and even the orange striped panties she was wearing underneath.
After spinning around once in delight, Se-young walked toward the changing room.
She went inside and came back out carrying a desk mirror, a hairdryer, a round brush, and a lilac hair tie.
Then, she scurried over to the kitchen where Mom was and placed the items on the dining table.
"Mom~ dry my hair for me~ Hehe~"
Se-young turned a dining chair so it faced the living room TV and sat down, speaking to Mom in a friendly tone.
"O-okay..."
Mom’s awkward voice drifted over from the corner of the kitchen.
Hearing Mom’s response, Se-young settled into the chair.
Mom approached the back of the chair where her daughter sat, the bell on her collar tinkling with every step.
"How... how should I do it?"
Mom asked Se-young what kind of hairstyle she wanted.
"Braid it like you did when we went to the department store last week~ Hehe."
Se-young answered in her usual tone.
As she sat, she swung her legs back and forth, crossing them in a playful, rhythmic motion.
Her body swayed in a cute, endearing way.
—Whirrrrrrr!
Soon, the sound of the hairdryer filled the kitchen.
Since Se-young had turned the chair toward the living room, Mom, standing right behind her, was naturally looking toward the living room where Si-woo was.
The red dog collar’s leash trailed out from under Mom’s clothes.
No matter how one looked at it, Mom’s attire was bizarre.
Sitting on the living room sofa, Si-woo turned his head toward the kitchen, and his eyes intermittently met Mom’s.
Every time they did, Mom would flinch awkwardly and quickly avert her gaze into thin air.
Se-young, sitting right in front of her, left her hair in Mom’s hands while glancing back and forth between the TV and Si-woo, her eyes meeting his frequently.
With a giggling smile, Se-young changed from swinging her legs back and forth to spreading them wide and then closing them.
When her legs parted, a wide gap opened up under her skirt.
The orange striped panties she was wearing were clearly visible beneath the light blue dress.
A strange sense of excitement washed over Si-woo, causing his erect cock to throb incessantly.
In the morning light, in the space connecting the living room and kitchen, a peculiar exchange of glances continued between the mother, the daughter, and Si-woo.
Si-woo let his gaze wander up and down, watching the two of them with appreciation, taking in their sensual appearance until Se-young’s hair was finished.

"I’m heading out, Mom!"
Having finished his preparations to leave, Si-woo gave Mom a brief farewell.
"I’ll text Se-hee as soon as I leave, so tell her to be ready! Got it?"
Si-woo added, reaffirming the instructions he had given her during breakfast.
"Yes... r-right... have... a safe trip..."
Standing at the entrance, Mom answered without being able to meet Si-woo’s eyes.
Her hands were clasped in front of her groin, as if she were trying to hide her secret shame from her children.
In the center of Mom’s voluptuous breasts, covered by her purple T-shirt, her nipples stood out hard and prominent, as if they were about to poke through the fabric.
The red collar around her neck and the attached red leash had been tossed over her shoulder, hidden behind her back.
"Mom! That outfit and the collar really look good on you~ Hehe!"
Se-young scanned Mom from top to bottom and complimented her outfit.
"I’m going to the department store with Oppa, so you stay here and watch the house with Se-hee Unnie!"
Se-young spoke in a tone one might use when giving instructions to a pet.
As she spoke, she moved closer to Si-woo and linked her arm with his, pressing her breast against him.
Through the light blue dress and his shirt, he could feel the soft, squishy sensation of Se-young’s breast.
"Y-yes... Se-young, you be careful too while you're out with your brother..."
Mom didn't object or argue against Se-young’s somewhat rude tone and provocative behavior; she simply complied.
As she answered with her head bowed, Mom’s face was as crimson as the leather collar around her neck.
A hot, heavy breath escaped her lips.

Si-woo left the house with Se-young.
It was just past 9:00 AM.
Si-woo walked while using his crossbody bag to hide the erection straining against his clothes.
Se-young kept her arm linked with Si-woo’s from the moment they left the house.
With every step, she clung to his arm for balance, her breasts moving back and forth and pressing against him.
Si-woo intentionally tensed his arm to resist, crushing Se-young’s breast against his side.
He enjoyed the feeling of that elastic flesh pressing against his arm.
It seemed they were both conscious of each other’s movements, but throughout the walk, Si-woo and Se-young acted as if they weren't aware of the highly inappropriate, non-platonic physical contact happening between them.
While subtly rubbing against Se-young’s breast with one arm, Si-woo pulled his smartphone out of his pocket with his other hand.
He opened the chat window with Se-hee Noona and began to type.
[I’ve left the house with Se-young, so head downstairs and give Mom the condom with my semen in it!]
Si-woo issued the command for Se-hee Noona to carry out the planned task.
[Got it. I’m going down now. But do I just give this to Mom?]
Se-hee Noona replied obediently but asked for clarification.
[Yeah... tell her to eat it! And start recording the video now! I told Mom she has to use formal speech with you while I’m gone, so if she uses informal speech, don't let her get away with it! Got it?]
Si-woo began to give Se-hee Noona detailed instructions and warnings.
[...But I’m a little scared. What if Mom gets mad at me while you’re not here? I’m really scared of getting in trouble with her~ Can’t we do this next time when you’re around?]
Se-hee Noona pleaded, clearly uncomfortable and worried about having such a sexual interaction with Mom in Si-woo’s absence.
[We have to do what we agreed on! You know how Seon-mi has been acting yesterday and today, right? Seon-mi said she’d do it earlier, too!]
Si-woo spoke, using Mom’s name, Seon-mi, casually to reinforce the current hierarchy within the family to Se-hee Noona.
Se-hee Noona didn't respond immediately, seemingly hesitating.
[Don’t worry! It’ll be fine. If you’re that worried, should I talk to Seon-mi one more time? Would that help?]
Si-woo spoke soothingly to the whining Se-hee Noona.
[...Are you going to talk to her now?]
Se-hee Noona was silent for a moment before reacting to Si-woo’s offer to speak to Mom again.
[I’ll do it now. It’s not hard! Hold on!]
Si-woo immediately switched chat windows and messaged Mom.
[Se-hee is coming down now! Be ready! And for today, while I’m gone, Se-hee is your superior, so watch your attitude! If I hear any complaints from Se-hee later, I’ll beat your ass until it’s raw!]
Si-woo spoke to Mom with a stern warning.
[Yes... I’ll be careful...]
Mom answered submissively, as if she had given up everything in the face of Si-woo’s harsh warning.
Had she realized that saying anything else to Si-woo was useless?
Seeing Mom’s almost hollowly obedient reply, a sadistic urge welled up inside Si-woo for some reason.
He imagined Mom falling into an even more humiliating and shameful state of pleasure after swallowing his semen in front of Se-hee Noona.
[Do whatever Se-hee tells you to do while I’m gone today! Got it?]
Si-woo asked, as if demanding a vow of absolute obedience to Se-hee Noona.
[I understand... I’ll do that...]
Mom, as expected, answered Si-woo’s text submissively.
—Even though this was the 1:1 chat room where they had promised to interact as mother and son...—
After what happened with Se-young this morning, Mom was treating Si-woo like someone who had lost her mind.
The fact that her secret had been exposed to Se-young, following Se-hee Noona, seemed to be a massive shock to her.
Si-woo screenshotted the conversation with Mom and sent it to Se-hee Noona as confirmation.
