Jinwoo carefully wiped his own cum off aunt Gyuri's face using his mom's panties.
But the panties had more of mom's juices than expected, so it felt more like he was smearing a mix of his cum and mom's juices across aunt Gyuri's face rather than wiping it off.
With no other choice, Jinwoo scraped the clumped up mucus off aunt Gyuri's face into her mouth.
Aunt Gyuri looked at Jinwoo with glazed eyes, her mouth slightly open, accepting his actions without any resistance.
Following Jinwoo's lead, aunt Gyuri swallowed down the mix of Jinwoo's cum and mom's juices that smeared her face, gulping it down.
Aunt Gyuri's breath, harsh and ragged, seemed to calm bit by bit.
Lastly, Jinwoo put his cock in aunt Gyuri's mouth once more.
Jinwoo intended to use Aunt Gyuri's mouth to clean his dirty cock.
Knowing what Jinwoo wanted, aunt Gyuri continued to lick his cock with her tongue, looking up at him with those unfocused eyes.
Every time her tongue touched Jinwoo's tip, he twitched.
The stimulation of the tongue on his genitals right after ejaculating was painfully intense.
Aunt Gyuri, finding Jinwoo's reactions amusing, playfully and vigorously licked the tip, stirring up more stimulation.
This playful torment, uncharacteristic of the usual aunt Gyuri, awakened some sadistic desire deep within Jinwoo.
It was as if aunt Gyuri was begging to be tormented more.
Jinwoo thought next time he'd make sure aunt Gyuri couldn't even think of such pranks by showing her their clear hierarchy.
After roughly cleaning up, Jinwoo took mom's panties and went into the changing room.
He threw the panties in the washing machine.
He fingered aunt Gyuri's pussy while forcing his cock into her mouth.
He shoved it down her throat until she almost gagged.
He came on her face and then used the panties soaked with mom's juices to gather the cum and fed it to her.
All this while exchanging messages with his mom in the living room where his mom could hear everything, feeling a bit sorry for Daeho, but the sense of conquest and fulfillment filling his chest was incomparable.

When Jinwoo came out of the bathroom after hastily washing his hands and genitals, his mom was hurriedly opening windows to ventilate the living room where the subtle scent of Jinwoo's semen was lingering.
It was a delicate situation; Sohee, Minji, and Sua could notice something if they came out of their rooms, so caution was necessary.
Aunty Gyuri, feeling too embarrassed to face the mom, had covered her eyes with one arm and sprawled out as if exhausted and asleep.
Seeing Jinwoo come out of the changing room, his mom approached him with a disgusted expression and playfully punched him on the head.
"It's a joke! A painless one! Ah~ Be gentle!!!"
Mom had tolerated the sexually charged massages and erections Jinwoo had for his aunt and mom's friend.
After hearing Jinwoo's indecent remarks and even going so far as to take off her panties, mom, still wanting to maintain some semblance of maternal authority, only started nagging Jinwoo after everything was over.
"Alright, alright~ I'll be gentle with mom~"
Jinwoo responded casually with a smile.
To Jinwoo, his mom's attitude and actions felt like role-playing in children's pretend games.
Right now, mom wanted to play the role of a scolding mother and a son, casually dismissing the situation, and Jinwoo was faithfully acting to meet her expectations.
Mom's feelings were complicated and troubled.
Through a chance event, mom had given in to a nocturnal temptation towards her son, something a mother should never do.
A son filled with sexual desires towards his mom.
Mom knew well that if she tempted her son, he would give in at any time.
The first time she showed her breasts to Jinwoo was really by accident, so she believed there was no intentional temptation towards her son.
However, every time her breasts were exposed after that day, using the initial accident as an excuse and denying the intent of temptation was a clear self-deception.
A paradoxical self-deception formed as if in denial and confrontation of each other's awareness.
Mom believed that as long as this paradoxical deception, which seemed to be formed by an implicit agreement with her son, continued, the relationship between mother and son would also continue to be safely maintained.
But Jinwoo's actions were becoming bolder...
It was as if the only purpose of his actions was to blatantly point out and break down mom's complacent belief in the deception, creating an irreversible rift between day and night.

"Jinwoo, go to the convenience store and buy some hangover medicine!
The kids won't be able to go home at this rate~
You know the powdered kind, right?"
Mom gave Jinwoo the card, deliberately making her words sound more hectic.
Jinwoo took the card from mom and headed to the convenience store.
Stepping outside, Jinwoo texted his mom.
'Mom'
'What?'
Mom promptly replied.
'Are you mad?'
Jinwoo knew mom wasn't really mad but asked to check her mood.
'Why would I be mad?'
'Because I cheated with Aunty Gyuri?'
Jinwoo's probing question seemed playful.
'That's funny! People might think we're lovers!'
'Weren't we lovers? Maybe we should start now then?'
Jinwoo playfully teased his mom.
'Hello, I'm still your mom, you know?'
Mom jokingly responded but clearly set boundaries.
'Haha, so we're just mom and son for now?'
Jinwoo asked, as if confirming their current relationship.
'Why state the obvious?'
Mom seemed to have reconciled her feelings by now.
'Is it okay that I took off mom's panties?'
Jinwoo teased mom just for the fun of it.
'Ugh!! Really, you only ask mom to do weird things!!
How can you ask if it's okay after making such requests?'
Mom seemed embarrassed as expected.
'Mom, when we go out for dinner tonight, wear the skirt I choose, okay?'
Jinwoo instructed, recalling a short skirt mom had worn long ago.
'I don't know!! I'm embarrassed now!!'
Mom expressed her emotions with a playful tantrum, seemingly refusing.
Jinwoo found such reactions from mom quite adorable.
Jinwoo was thrilled that he could now chat this freely with mom.
Thinking about the special night they would spend together again made his steps lighter with anticipation.

Jinwoo returned home from the convenience store with the hangover remedy.
In the living room, Minji and Sua were playing, and his aunt seemed just to have woken up, leaning back on the sofa with a glass of water.
Aunt Gyuri was also sitting at the dining table with mom, drinking water, her makeup washed off.
By the time Jinwoo returned from the convenience store, both mom and aunt Gyuri had calmed down significantly.
"Are you feeling better, aunt Gyuri?"
Jinwoo approached the dining table, handed mom the bag with the hangover remedy, and started a conversation with aunt Gyuri.
"Yeah, I feel much refreshed thanks to you, Jinwoo~ Can I ask for another massage from you next time?"
aunty Gyuri talked about the massage nonchalantly, smiling in front of mom.
Jinwoo glanced at mom's expression discreetly.
Mom pretended not to notice and looked away, hiding her expression as she picked up a cup filled with water to drink.
"Next time, I'll go to aunt Gyuri's place and make sure you feel even more refreshed."
Jinwoo looked at mom while hinting at the next visit with Aunt Gyuri.
Mom glanced briefly at Jinwoo as he spoke, and when their eyes met, she quickly turned her head to look elsewhere.
Jinwoo found such reactions from mom endearing and approached to stroke her hair.
Mom, receiving Jinwoo's touch and blushing silently, looked around the living room.
Aunt Gyuri, watching mom, had a mischievous smile, indicating that the secrets between mom and Jinwoo were now being shared with her as well.
* * *
Shortly after, Jinwoo entered his mom's room and rummaged through her wardrobe drawer.
He found the shortest skirt among mom's clothes.
It was a pink flare skirt that would rise above the knees when worn.
Hoping that mom would follow his instructions, Jinwoo placed the pink flare skirt on the bed.
