Chapter 280 (Mom)

—Tak! Tak! Tak! Tak! Tak!
While receiving a lewd oral massage from Mom, Si-woo gripped his cock and stroked it with Se-young’s panties as if wringing it out.
Thick semen that had been smeared on Se-young’s panties dripped onto Mom’s smooth face.
The semen that trickled down the shaft of his cock also flowed into Mom’s mouth as she licked his scrotum.
Holding Si-woo’s semen in her mouth, Mom worked her lips and tongue together.
It was a sensation where ecstatically slippery pleasure and a stinging ache were exquisitely intertwined.
That mixed, unfamiliar sensation spread from Si-woo’s shaft and testicles, surging through his entire body.
Si-woo used the smartphone in his hand to film Mom’s face as it was pressed against his cock.
—Click! Click! Click!
Perhaps she knew how the photos on the smartphone would be used?
With every sound of the shutter, Mom’s face flushed a deeper shade of red.
Si-woo uploaded the photos to the group chat where Mom, Aunt Seon-ju, and Se-hee Noona were all present.
—Ding! Ding! Ding!
The notification sounds signaling the arrival of the photos rang out from Mom’s smartphone.
As if reacting to the sound, Mom’s body began to tremble violently.
"About Se-young’s breasts I saw this morning..."
Si-woo stopped his hand, which had been stroking his cock for a while, and spoke to Mom.
As if trying to focus on the words Si-woo uttered after pausing his movements, Mom also immediately stopped her tongue, which had been sweeping over his scrotum.
"I think she’s growing up to be more beautiful, just like you, Mom. When I saw them this morning, even the color of her nipples was so lewd. I wonder if those little things will eventually get as big as your breasts? It’s fascinating."
Si-woo spoke playfully, using Se-young’s breasts, which he had seen that morning, as his topic.
The pure white breasts that had been revealed when one shoulder strap of Se-young’s yellow sleeveless dress with a pink checkered pattern was undone.
As if intentionally trying to provoke Mom, Si-woo spoke to her using explicit terms, reminding her of what had happened in the kitchen that morning.
As soon as he started talking about Se-young, Mom’s breath began to puff out raggedly while her mouth was still stuffed full with his scrotum.
"I wonder if Se-young is planning to stop wearing bras now? She was bragging to me about it before... You saw her that evening after we went to the department store last week, didn't you, Mom?"
Si-woo spoke as he recalled Se-young, who had provocatively shown off her first time wearing a bra last weekend.
After returning from the department store and taking a shower, Se-young had lifted her outer clothes to show Si-woo her bra, even though Mom was right there in the kitchen.
It was a sudden, unexpected action from Se-young, unlike her usual self, which even gave the impression that she was disregarding Mom’s authority.
"Se-young seems to listen to me surprisingly well. Should I try suggesting she stop wearing panties in a roundabout way? I wonder if Se-young will start going around the house without panties now, just like you, Mom?"
Si-woo continued his lewd talk using Se-young as the subject, as if determined to keep provoking Mom.
At the suggestive and mischievous topic of conversation, Mom’s pupils shook wildly within her half-lidded eyes.
—Tak! Tak! Tak! Tak!
Watching her, Si-woo began to stroke his massive cock up and down again with Se-young’s panties.
It was as if he wanted Mom to know he was getting excited by imagining Se-young growing up without ever wearing a bra...
Thick, slippery pre-cum dripped from the tip of Si-woo’s penis, soaking Mom’s hair and forehead.
Looking up at Si-woo’s face with unfocused eyes, Mom’s lips and tongue began to move again in sync with Si-woo’s hand movements.
With the provocative movements of her mouth and tongue, as if she had completely abandoned her awareness as a mother, Si-woo felt like his testicles were about to melt.
Before long, the semen that had dripped from Se-young’s panties flowed down Si-woo’s hard shaft and filled Mom’s mouth.
"Gulp! Gulp! Gulp!"
Mom swallowed every drop of Si-woo’s semen that filled her mouth, sending it down her throat.
With Mom’s swallowing, Si-woo’s balls were pulled forcefully into her mouth.
His scrotum was sucked right up to the front of her throat by the powerful suction.
"Aaaah!"
Si-woo couldn't hold it back and let out a pained groan, his body jolting violently.
A squeezing pain, accompanied by a faint sensation of pleasure, once again bore down on Si-woo’s testicles.
A sudden pain felt in his lower abdomen was followed by a surging sense of climax.
"Ugh... Ah... Mmm..."
Si-woo let out a ragged groan but barely managed to endure the precarious verge of ejaculation.
Moving the hand that had been gripping Se-young’s underwear and stroking his penis, Si-woo placed it on top of Mom’s head.
Pushing Mom’s face away, Si-woo endured the moment of pleasure tinged with pain.
"Haa... Haa... Mmph... Haa..."
After swallowing all the semen that had been in her mouth, Mom opened her mouth and gasped for breath.
Si-woo pulled his hips back, extracting his testicles from Mom’s mouth.
Cringing slightly, Si-woo waited for the pain in his balls and the lingering pleasure to pass.
A dull, burning pain, as if they were bruised, radiated from his scrotum.
* * *
After some time had passed, the stinging pain in his testicles and penis, as well as the urge to ejaculate, seemed to gradually subside.
"Damn! I thought my balls were going to burst!"
Si-woo spat the words at Mom, his voice a mix of annoyance and relief.
As if a mischievous prank had suddenly occurred to him, Si-woo brought Se-young’s panties, which he was holding, to Mom’s head.
Then, he pulled Se-young’s panties over her head as if he were putting a knit cap on her.
The small piece of cloth, soaked with semen, stretched out and sat on Mom’s head like a thimble.
Mom knelt there in a vulgar posture, her body hunched as she looked up toward Si-woo’s face.
As if punishing Mom for her earlier actions, Si-woo grabbed his cock and swung it against the face of his mother, who was wearing Se-young’s panties on her head.
—Thwack! Thwack! Slap!
The massive shaft was swung back and forth, striking both of Mom’s cheeks.
Every time Si-woo’s large, heavy meat stick struck her cheeks alternately, Mom flinched and shrank back.
In the face of this humiliating punishment, Mom seemed to have completely abandoned her awareness as a mother at that moment.
Her face was entirely slackened in submission as she breathed heavily.
Si-woo filmed the sight of Mom being struck on the cheeks by his penis while wearing Se-young’s panties on her head.
—Ding!
Mom’s face, captured on the smartphone screen, was flushed a deep crimson.
Mom leaned her face forward and stared into the camera lens, accepting the humiliating violence inflicted by her son.
Clicking the stop button with a satisfied look, Si-woo saved the video to his smartphone.
This time, Si-woo didn't upload the video of Mom to the group chat with Aunt Seon-ju and Se-hee Noona, but to his 1:1 chat window with Se-young.
Since Mom had hidden Se-young’s smartphone, there was no way Se-young would see the video.
However, the mere fact that a humiliating video of Mom had been sent to Se-young’s smartphone seemed enough to inflict an even more miserable and precarious sense of humiliation upon her.
He thrust the smartphone in front of Mom’s face, letting her confirm for herself that the shameful photo of her had been uploaded to the chat window with Se-young.
Whether from the surge of shame at her own appearance, Mom’s body trembled even more violently than before.
Without a word, Si-woo brought his cock to Mom’s mouth.
Mom now stuck out her tongue and licked Si-woo’s massive shaft from the bottom up.
Then, she wrapped her lips around Si-woo’s semen-stained meat stick and began to suck on it industriously, moving up and down.
"I think it would be better if you didn't wear a bra either, Mom..."
Looking down at Mom as she licked and sucked his penis with her tongue and lips, Si-woo gave her an instruction—or rather, a command—in a nonchalant tone.
Being a mother born with a masochistic nature, there was no way she would disobey Si-woo’s words, just as she had shown until now.
At the thought of the mother and daughter eventually living without any underwear, blood rushed to Si-woo’s member once again.
Mom took the red flesh protruding from the tip of Si-woo’s shaft into her mouth.
Si-woo’s penis slid into Mom’s soft, wet mucous membranes as if melting into them.
Mom began her foreplay by wrapping her tongue around his penis and swirling it clockwise.
Every time the sensitive glans was rubbed by Mom’s tongue, a thrilling shiver ran through Si-woo’s penis.
That electrifying pleasure, which felt like it was scorching his skin, soon spread through Si-woo’s entire body like a vibration.
Si-woo briefly set his smartphone down on the bedside table next to him.
Then, he reached out with both hands and cupped Mom’s head, which was still covered by Se-young’s panties.
The urge to ejaculate surged up from the tip of his cock, feeling as if it would explode at any moment.
Barely suppressing that urge, Si-woo shoved his massive tool deep into Mom’s mouth.
