Chapter 439 (Mom) (On the Way Home, Residential Area)

Mom was walking through the familiar streets near our house with her groin and buttocks completely exposed to the outside air.
The sight was as alien as it was provocative, making Si-woo’s penis twitch incessantly inside his clothes.
Si-woo scanned the surroundings before shifting the crossbody bag that had been covering his front to the side.
He flipped up the hem of his T-shirt, which had been covering the top of his shaft, and eased his pants down slightly to pull his penis out.
More than half of the massive flesh pillar was now exposed, jutting out into the open.
Si-woo sidled up to Mom and pressed his exposed penis against her bare buttocks.
Mom’s pace faltered instantly, her buttocks tensing and tightening in a reflexive flinch.
Slap!
Si-woo delivered a sharp smack to her backside from behind.
"Hngh!"
A moan escaped Mom’s lips, sounding as if she were suppressing a surge of pain rising from deep within.
"Who told you to stop?"
Si-woo spoke to her in a threatening tone.
Mom stood there for a moment, seemingly enduring the pain and humiliation radiating from where Si-woo’s palm had struck her, before she silently began to walk again.
Following close behind her, Si-woo repeatedly pressed his penis against her buttocks and pulled it away.
He then wedged the tip of his glans into the crack of her buttocks and began to rapidly pump his shaft up and down.
Thwack, thwack, thwack, thwack, thwack!
The sound of his masturbation—part of this exhibitionism play with his mother in the middle of a public residential street—echoed through the night air as if melting into it.
After vigorously stroking his massive shaft against her, Si-woo pulled his penis away from her buttocks and resumed walking a short distance behind her.
Mom’s body swayed momentarily as if she were losing her balance once the contact was broken, but she quickly steadied herself.
For a while, Si-woo walked on, admiring his mother’s exposed rear.
The voluptuous, seductive movement of her buttocks swaying left and right made his heart race.
The juices leaking from between Mom’s legs were now so abundant they threatened to soak the very asphalt they were walking on.
* * *
Si-woo and Mom walked in silence for some time.
Up ahead was a familiar corner in the residential alleyway.
Once they turned that corner, the house would be less than a hundred meters away.
Walking ahead, Mom rounded the corner with cautious steps.
The moment she turned, her body jolted. She hurriedly let go of the hem of the cardigan she had been holding up above her waist.
Seeing her reaction, Si-woo also flinched and stepped back from her, quickly swinging his crossbody bag back around to hide his penis.
Following her cautiously around the corner, Si-woo immediately understood why Mom had lowered her cardigan in such a panic.
In the distance, a figure could be seen putting out a plastic bag of trash in front of a house.
It was the face of a middle-aged woman he recognized from passing by before.
Was it the house with children around Se-young’s age?
The familiar middle-aged woman set down the trash, organized the recyclables, and was about to head back inside.
Then, as if recognizing Mom’s face, she turned toward them.
"Oh my, are you coming back from grocery shopping?"
The middle-aged woman gave a friendly nod and greeted Mom, appearing genuinely pleased to see her.
"Ah... yes... I’m just on my way back from the mart to get some things for dinner..."
Mom replied awkwardly, clutching the lowered cardigan tight and using her body to shield Si-woo behind her.
Fortunately, the neighbor organizing the trash didn't seem to find anything unusual about Mom or Si-woo.
"I see! Well, have a delicious dinner then!"
The neighbor didn't try to strike up a longer conversation or approach them. After finishing with the trash, she gave a final greeting and quickly disappeared into her house.
It had been a brief moment, but the encounter was enough to make their hearts race with tension.
Having run into a familiar neighbor the moment she turned the corner, Mom had lowered her cardigan in a fright to hide her groin.
Her pace was now noticeably slower than it had been before they turned the corner.
"I don't recall giving you permission to pull that down...?"
Si-woo spoke in a low voice, almost like a mutter, from behind her.
"Th-that... just now... there was someone... someone I know..."
Mom stammered out an excuse, sounding completely cowed and intimidated.
"There’s no one here now..."
Si-woo murmured again, his voice dropping even lower.
"Yes... yes... th-there’s no one now... Sigh..."
Mom let out a heavy sigh at Si-woo’s words... and gripped the hem of her cardigan as if to pull it back up.
However, perhaps due to the shock of the encounter with someone she knew, she couldn't bring herself to hike the cardigan up as easily as she had before.
Si-woo pushed the bag hiding his penis to the side and pressed his massive, exposed flesh pillar against her buttocks like a prod.
"Hngh!"
Mom stood there, looking as if she were terrified that Si-woo’s palm would come crashing down painfully on her backside again.
She trembled and flinched, her body wracked with nerves and intimidation.
"Looks like our Seon-mi needs a little discipline before we go inside!"
Si-woo spoke to Mom in a tone one might use to scold and coax a puppy that wasn't listening during a walk.
With her hands raised awkwardly in the air, Mom struggled to gather the hem of the cardigan and pull it back up above her waist.
Yet, the hem wouldn't go up easily, as if she were still worried about running into another neighbor.
At the same time, her body shook with tension, as if she were waiting for the spanking from Si-woo that could fall at any moment.
Si-woo watched her for a moment, a look of satisfaction on his face.
Then, he brought his palm down, tapping her buttocks lightly.
Mom gave a violent start, her hips jerking forward in surprise.
"Hngh!"
Realizing that the hand on her buttocks wasn't a powerful strike, Mom let out a sound of embarrassment.
"I texted Se-hee to tell her we’re coming home now. Along with that photo of you I took earlier, Seon-mi..."
Si-woo changed the subject, stroking Mom’s buttocks with a gentle touch as if he wouldn't force her any further.
"What?... Ah, yes... yes... Haaah..."
Hearing Si-woo’s words, the strength left Mom’s hands as they gripped the cardigan. A sigh—whether of resignation or relief—escaped her lips.
"She said Se-hee’s friends finished cleaning up and went home, so I don't think there’s anything else to worry about."
Si-woo spoke as if relaying the contents of the text messages he had just exchanged with Se-hee Noona.
"I see..."
Mom replied, sounding as if she understood.
"But still, Se-hee and her friends were quite mischievous, making you go on a cigarette run like this, Seon-mi!"
"I’ll make sure to set things straight with Se-hee’s friends later! So don't worry about that either!"
Si-woo added, as if explaining how he had settled the situation.
"Yes... I... I’d appreciate that..."
Mom replied in a voice thick with embarrassment, her head hanging low.
After speaking, Si-woo pressed his exposed penis against her buttocks again to urge her forward.
Mom flinched as her buttocks tensed in surprise, but she soon returned to her original walking pace.

Before they knew it, Si-woo and Mom had reached the street where their front gate was visible.
"I wonder if it took about two or three minutes?"
Si-woo spoke as he continued to walk behind her, his genitals still exposed outside his pants.
"Pardon?"
Mom reacted with confusion to Si-woo’s sudden, cryptic remark.
"Earlier, you lowered that cardigan that was hiked up to your waist without my permission, didn't you?! I’m talking about the time it took to walk from that corner to here in that state!"
Si-woo’s voice suddenly dropped into a low, threatening register, setting a heavy atmosphere.
"Th-that’s... because there was someone out there putting out trash... Y-you saw them too, Master..."
Mom replied frantically, sensing the threat in Si-woo’s low voice.
"And after that person went inside? You didn't hike the cardigan back up, did you? Even though I still had my cock out!"
Si-woo interrogated her, his tone refuting her excuse.
"Th-that’s... because Master... was touching my buttocks and talking to me... I thought it was okay..."
Mom stammered, sounding distressed and cornered.
"Who the fuck said it was okay, Seon-mi, you fucking bitch?! Should I just not let you go home today and make you walk around like that? Want to go to the convenience store again?"
Si-woo threatened her harshly.
"M-Master... I was wrong... P-please forgive me just this once."
Mom turned toward Si-woo, pleading with him.
It seemed she already realized that no matter what she said, she couldn't escape the flow of the play Si-woo had planned.
Her expression had shifted, looking as if she were on the verge of tears.
