Chapter 28 (Mom, Aunt Seon-ju, Aunt Gyu-ri) (Si-woo's House)

Si-woo carefully wiped the semen off Aunt Gyu-ri’s face using his mom’s panties.
However, the panties were soaked with more pussy fluid than he had expected. Rather than wiping her clean, it felt more like he was spreading a mixture of his semen and his mom’s pussy fluid across Aunt Gyu-ri’s face.
Left with no choice, Si-woo gathered the clumps of mucus that had pooled on her face and pushed them into Aunt Gyu-ri’s mouth.
With glazed eyes, Aunt Gyu-ri looked up at Si-woo, her mouth slightly parted, accepting his actions without a hint of resistance.
She gulped down the mixture of Si-woo’s semen and his mom’s pussy fluid just as he fed it to her.
Her ragged, heavy breathing was finally beginning to settle, bit by bit.
Lastly, Si-woo pressed his large cock into Aunt Gyu-ri’s mouth once more.
He intended to use her mouth to clean his soiled dick.
As if sensing his intent, Aunt Gyu-ri kept her unfocused eyes on his face while her tongue licked up the length of his shaft.
Every time her tongue swept over his glans, Si-woo’s body flinched.
The stimulation of a tongue against his genitals immediately after ejaculation was so intense it was almost painful.
As if finding his reaction amusing, Aunt Gyu-ri carefully cleaned his cock, occasionally giving him a playful look while flicking her tongue sharply and quickly over the glans to tease him.
Seeing this side of her—a playfulness so unlike her usual self—Si-woo felt an indefinable sadistic desire surge from deep within his chest.
It was as if she were acting out, begging to be tormented even more.
Si-woo decided that next time, he would push Aunt Gyu-ri to her absolute limit, making sure she understood their master-slave relationship so clearly that she wouldn't even dream of playing such pranks.
After finishing the cleanup, Si-woo took his mom’s panties and headed to the changing room.
He tossed the soiled panties into the washing machine.
He had thrust his fingers into Aunt Gyu-ri’s pussy and forced his cock into her mouth.
He had shoved himself in so deep she gagged, and he had pounded away.
He had ejaculated on her face and then used his mom’s fluid-stained panties to gather the semen and feed it to her.
And he had done all of this in the living room, where his mom could hear everything, while exchanging messages with her. He felt a slight pang of guilt toward Cheol-jin, but it was nothing compared to the overwhelming sense of conquest and satisfaction currently filling his heart.

By the time Si-woo finished washing his hands and his cock in the bathroom and stepped out, his mom was hurriedly opening windows everywhere to ventilate the house.
The faint scent of semen was lingering in the living room.
They had to be careful; if Se-hee Noona, Se-young, or Su-a came out of their rooms, they might notice.
Aunt Gyu-ri, perhaps too embarrassed to face his mom immediately, lay sprawled out as if exhausted and asleep, one arm draped over her eyes.
Mom approached Si-woo as he came out of the changing room. With an exasperated expression, she balled her hand into a fist and gave him a playful rap on the head.
It was a light, teasing gesture that didn't hurt at all.
"Good grief! You should have been gentler! You're going to end up killing Gyu-ri at this rate!"
Mom had turned a blind eye to her son’s sexual "massages" and his erections in front of her sister and her friend.
Even after being subjected to his harassment and molestation—and even giving him her panties—it seemed she still wanted to assert some semblance of maternal authority now that the deed was done. She continued to nag him.
"Alright, alright. I'll be gentle when it's your turn, Mom."
Si-woo replied with a relaxed smile.
To him, his mom’s attitude and behavior felt like role-playing in a game of house.
Right now, she wanted to play the role of a mother scolding her son for his mistakes, and he was playing the part of the son who playfully brushed it off, dutifully following her lead.
In truth, Mom’s heart was a tangled mess of confusion.
Through a series of coincidences, she had realized her nighttime temptation of her son—something a mother should never do.
And she had a son who was overflowing with sexual desire for her.
She knew, of course, that if she ever chose to seduce him, he would fall for it instantly.
She told herself that the first time she showed him her breasts was a complete accident, and therefore, she’d had no intention of seducing him.
But to continue denying that intent even as her breasts were exposed time and time again after that day was nothing short of self-deception.
It was a contradictory deception, formed as if their conscious minds were clashing while simultaneously denying the truth.
Mom believed that as long as this contradictory deception—built on a tacit agreement with her son—remained intact, their relationship as mother and son would also remain safe.
But Si-woo’s actions were becoming increasingly bold...
As if he were blatantly pointing out her naive belief in that deception, he was creating irreversible fissures in the boundary between day and night, as if his only goal was to tear down the walls of their relationship.

"Si-woo, go to the convenience store and buy some hangover medicine! The girls won't even be able to get home at this rate. You know the powdered kind, right?"
Mom handed Si-woo her card, her voice sounding intentionally more frantic than necessary.
Si-woo took the card and headed toward the convenience store.
Once he was outside the house, he sent her a text.
[Mom.]
[What?]
She replied instantly.
[Are you mad?]
Si-woo knew she wasn't, but he asked anyway to check her mood.
[I'm not mad. Why would I be?]
[Because I 'cheated' with Aunt Gyu-ri?]
Si-woo asked, testing the waters.
[Oh, please! Someone might actually think we're dating if they heard you.]
[We weren't? Well, I guess we can just start now.]
Si-woo joked slyly.
[Excuse me? I am still your mother, you know.]
She played along with the joke but made sure to draw a firm line.
[Haha, so for now, we're just mother and son?]
Si-woo asked, as if confirming their current status.
[Why are you stating the obvious?]
Mom seemed to have composed herself now.
[Are you okay with me taking your panties?]
Si-woo teased her further.
[Ugh!! You really make your mom do the strangest things!! How can you ask if I'm okay after making me do that?]
As expected, she sounded embarrassed.
[When we go out for dinner tonight, wear the skirt I pick out for you. Got it?]
Si-woo gave her an order, recalling a short skirt she used to wear a long time ago.
[I don't know!! I'm too embarrassed now!!]
She protested playfully, expressing her feelings like a coy girl.
Si-woo found her incredibly cute.
He was thrilled that he could now have this level of conversation with her over chat.
Thinking about the special night he would spend with her again, his footsteps felt light with anticipation.

Si-woo bought the hangover cures at the convenience store and returned home.
Se-young and Su-a were playing in the living room, and Aunt Seon-ju was sitting on the sofa, leaning back with a glass of water, looking like she had just woken up.
Aunt Gyu-ri was also at the dining table with his mom, drinking water. Her makeup was gone, suggesting she had washed her face.
In the time Si-woo was gone, both his mom and Aunt Gyu-ri had calmed down significantly.
"Are you feeling better, Aunt Gyu-ri?"
Si-woo walked to the table, handed the plastic bag with the hangover medicine to his mom, and spoke to Aunt Gyu-ri.
"Yeah, I feel refreshed thanks to you, Si-woo. Can I ask you for another massage next time?"
Aunt Gyu-ri mentioned the massage casually in front of his mom with a smile.
Si-woo stole a glance at his mom’s expression.
Mom pretended not to notice, looking away to hide her face as she took a sip of water.
"Sure. Next time, I'll go to your house so I can make you feel even more refreshed."
Si-woo looked at his mom as he foreshadowed his next encounter with Aunt Gyu-ri.
Mom glanced toward him, but the moment their eyes met, she quickly turned her head away.
Finding her reaction adorable, Si-woo walked over and stroked her hair.
While keeping an eye on the living room, Mom stayed silent and let him touch her, her face flushing red.
Aunt Gyu-ri watched them with a suggestive smile.
The secret he shared with his mom was now being shared with Aunt Gyu-ri as well.

A short while later, Si-woo went into his mom’s room and rummaged through her dresser.
He found the shortest skirt among her collection.
It was a pink flare skirt that would sit well above the knee when worn.
Hoping his mom would follow his instructions, Si-woo laid the pink flare skirt out on the bed.
