Chapter 420 (Mom)

Si-woo’s bare cock, unburdened by a condom, was buried deep within Mom’s fissure.
The mucous membranes and ridges of Mom’s vaginal walls—a sensation he was tasting for the first time—rubbed vividly against the raw skin of Si-woo’s shaft and glans.
The ecstatic touch of her bare vaginal walls felt as if it would melt Si-woo’s very brain.
Bzzzzzzzz! Bzzzzzzzz! Bzzzzzzzzzz!
Along with the slick, wet sensation of the vaginal walls, the vibration of the vibrator pulsed through to Si-woo’s penis.
The vibrations were being transmitted through Mom’s vaginal walls and labia, which were clamped tightly around his penis.
Mom’s vaginal flesh clung to Si-woo’s penis, repeatedly tightening and releasing in a convulsive, surging rhythm.
The vibrations and the clenching were so ferocious that they made Si-woo’s penis tingle and go numb the moment it was buried inside her pussy hole.
Had Mom been enduring this kind of stimulation from the vibrator all this time?
Si-woo kept his penis buried inside Mom’s pussy hole for a moment, curling his body forward as he desperately suppressed the intense stimulation rising from his core.
After barely passing the peak of his climax and catching his breath, Si-woo straightened his back and placed his hands on Mom’s buttocks.
The mucous membranes of Mom’s vaginal walls still clung to Si-woo’s penis without a single gap, creating a subtle, rubbing friction.
Smack!
Si-woo delivered a sharp, heavy blow to Mom’s defenseless buttocks.
It was partly because he remembered Aunt Seon-ju saying that Mom loved being slapped on the ass while being plowed from behind, but it was more an expression of respect and awe for the sensation of Mom’s bare vaginal flesh, which had brought him to the brink of climax in such a short time.
"Haa-ah!"
Slumped over the table, Mom let out a short moan, her vaginal flesh twitching and tightening around his penis.
Si-woo grabbed Mom’s waist and applied just enough pressure to shove his penis as deep into her hole as possible.
Squelch!
Si-woo’s penis buried itself deep inside her, as if pushing up against Mom’s womb.
"Hnghhhhh..."
Mom’s body trembled violently as she let out a low moan.
Maintaining that depth, Si-woo leaned forward until his chest pressed against Mom’s back.
With his penis deeply inserted into her hole, he pinned her down, his body flush against her back.
In that position, Si-woo reached forward and slid his palms under Mom’s breasts.
He began to cup and knead Mom’s large breasts.
Mom’s large, elastic breasts shifted and distorted under Si-woo’s hands like mounds of dough.
Si-woo pulled his waist back slightly and began to slowly grind his penis back and forth, creating friction within Mom’s pussy hole.
Schlick, schlick, squelch!
The wet sound of his penis tightly filling and rubbing against the vaginal walls echoed between them.
While kneading her breasts, Si-woo continued to scrape against the inside of her vaginal walls with his rhythmic thrusts.
"Haa-ah... Haa-ah... Haa-ah..."
A pained, yet pleasurable moan escaped Mom’s lips, perfectly timed with the movement of Si-woo’s waist.
* * *
The tight, intricate clenching of Mom’s bare vaginal flesh provided Si-woo’s fully erect penis with a sense of ecstatic fulfillment and vivid pleasure.
The soft, heavy weight of her breasts, the nervous trembling of Mom’s body, her ragged breathing, and the heat and lewd scent of sweat filling the room...
Everything seemed to act as an element that multiplied the satisfying pleasure Si-woo was experiencing.
Si-woo moved his penis slowly on purpose, as if savoring the texture of Mom’s bare vaginal flesh.
He also synchronized the speed of his hands, which were supporting and cupping her breasts, with the movement of his penis.
"I noticed Se-young’s breasts have grown quite a bit lately, haven't they? Kids really do grow up fast. Don't you think?"
Si-woo questioned Mom, as if continuing the conversation they had before insertion.
"Hngh!"
Mom seemed to falter for a moment at Si-woo’s question; she caught her breath and squeezed her pussy hole tight.
"Haa... Y-yes... Hngh, Se-young... she really has grown a lot..."
Mom eventually exhaled and replied, as if responding to Si-woo’s comment about their daughter.
"If she keeps growing like this, she’ll catch up to Se-hee’s chest in no time. Though I guess reaching this size might be impossible?"
Si-woo spoke about Se-young’s growth potential while kneading and crushing Mom’s breasts at his whim, comparing them to her daughters'.
"Haa... Hu-aaaaah~"
Mom’s breathing became ragged and irregular, like someone who didn't know how to react.
"Oh, right! I heard you like sucking someone else's nipples while being plowed, Mom?"
Si-woo asked directly, recalling what Aunt Seon-ju had said to tease Mom in the group chat.
"Haa... Yes... I... I like that. Things like that too..."
This time, Mom answered Si-woo’s question immediately, without catching her breath or hesitating.
"It must have felt great when you were being plowed by Dad while sucking on Gyu-ri’s nipples, right? Wasn't it?"
Si-woo asked, recalling the scene from the Fetal Wedding photo Aunt Gyu-ri had given him.
Si-woo was testing her with a mischievous tone, asking questions that were difficult for her to answer.
"Hnghhhh..."
Mom couldn't give a proper answer, only letting out a sharp intake of breath.
"Have you sucked Seon-ju’s nipples too?"
Without waiting for an answer, Si-woo continued with questions that a normal mother would find impossible to answer.
"Huu... Haa... Yes, yes... I’ve sucked them. A long time ago..."
Mom answered as if confessing to Si-woo, her breath hot and heavy.
It seemed Mom was more comfortable talking about Aunt Seon-ju than anyone else.
As Si-woo imagined Mom sucking Aunt Seon-ju’s nipples, his penis throbbed and swelled inside her pussy hole.
"Haa-ahng...!"
Mom’s waist arched as her upper body jerked.
Si-woo found Mom’s nipples and pinched them between his fingers.
He began to rub and flick them up and down, catching the nipples between his fingertips.
"Hnghhhh... Haa-ahhh... Haa-ahhh..."
Mom let out moans that sounded overwhelmed by excitement.
"We’ve done it before where you were being plowed while Se-young was latched onto your breast, right? But have we ever done it where you were being plowed while sucking Se-young’s breasts?"
Si-woo asked provocatively, trying to recall the hazy memories of the previous night.
"But since that happened while Se-young was asleep, I guess it doesn't really count, does it?"
Si-woo stopped the movement of his waist and rubbed his entire palm over her nipples to make her focus on the stimulation he was providing.
"Tonight, while Se-young is awake, try being plowed by me while you properly suck her breasts."
Si-woo’s words were no longer a suggestion; they were a command.
Mom closed her eyes tightly, seemingly trying to steady her frantic breathing.
Then, at some point, she suddenly pressed her thighs together and her body jerked as if she couldn't take it anymore.
Si-woo released her breasts and straightened his waist.
"I’ll talk to Se-young about it, so don't worry!"
Si-woo spoke as he pressed down on Mom’s upper body to keep her from bouncing up, slowly pushing his penis back in.
Her pussy hole, which had been slumped over and tightly gripping Si-woo’s penis as if paralyzed, suddenly began to convulse violently.
"Haa-ahhh... Haa-ahng... Haa-ahhh... Haa-ahhh!!"
Whether she no longer had the composure or the strength to suppress the surging pleasure, Mom began to let out shameless, vulgar moans while pinned beneath Si-woo.
Was Mom imagining sucking Se-young’s breasts while being plowed by Si-woo’s penis on the bed right now?
Si-woo moved his hand from her back down to her buttocks.
He raised his hand high, preparing to strike Mom’s ass once more.
Smack! Smack! Smack!
A cruel punishment for the climax she had reached on her own.
As if expressing contempt and anger toward her vulgar moans, Si-woo continued to lash out at Mom’s swollen buttocks.
"Hngh! Ha! Haa-ah!"
In the middle of her climax, the pain blooming on her buttocks made Mom twist her body and let out pained groans, looking like someone who didn't know what to do.
"Answer me properly, you fucking bitch! What are you acting all shy for, you perverted cunt who even made a slave declaration in front of the whole family?"
Si-woo spoke to Mom, his voice laced with anger and profanity.
"Yes... Yes! Hngh... Tonight, while being plowed by Master’s cock... I’ll... I’ll suck... Se-young’s... breasts... Hngh... Please... please talk to Se-young for me. I beg you... Hnghhhh..."
Mom supported herself on legs that looked like they would collapse at any moment, trembling violently.
Her pelvis and thighs shook incessantly as she pleaded with Si-woo in a voice that was almost a sob, uttering those lewd words.
At Mom’s words about sucking Se-young’s breasts, a surge of climax rushed to the tip of Si-woo’s penis.
Si-woo bit his lower lip and endured the oncoming sensation of climax once again.
Whether it was because of his bladder full of urine or the vibration of the vibrator echoing in his groin, a thrill spread through his fingertips and toes.
Of course, the urine in his bladder, the vibration of the vibrator, and the lewd words coming from Mom’s mouth could have all played a major role in the two near-ejaculations Si-woo had just experienced.
However, having survived two crises of ejaculation in such a short time inside Mom’s body, Si-woo began to wonder if Mom’s pussy was a masterpiece unlike any other in the world.
As that thought took hold, a sadistic instinct toward Mom and a destructive desire for dominance filled Si-woo once again.
