    Siwoo takes out the smartphone he had put in his pants pocket.

    Then, after displaying the app for operating the vibrator on the screen, Siwoo adjusts the intensity to the maximum level.

    Giaaaaaang!

    The vibrator, attached to the front of Mom’s crotch, vibrates violently, making a loud noise.

    The intense vibration of the vibrator was transmitted as is to Siwoo’s penis inside her body, along with the squeezing of the vaginal walls.

    The powerful power of the vibrator that seems to resonate to the brain.

    “Haaaang… Hooaaat… Hieuuuut! Hueueueung!”

    Due to the unexpected intensity of the vibration, Mom’s knees bend as if she is about to collapse regardless of her will, and her posture is becoming disheveled.

    When the vibration of the vibrator rises to the maximum intensity, Mom bends her body forward as if struck in the abdomen, and makes a moaning sound close to a cry.

    “Put strength in your legs! You fucking cunt! Straighten your knees out too!”

    Siwoo cursed at his mother and gave an overbearing order.

    Slap!

    At the same time as the words end, Siwoo strikes Mom’s buttocks strongly.

    “Haeueut!”

    Mom spits out a moan filled with pain and barely tries to correct her collapsing posture.

    However, perhaps because she doesn’t seem to be able to put strength into them, her legs, gathered inward, stagger like a newborn fawn.

    Siwoo wraps his arms around Mom’s pelvis below her waist and supports her as if lifting her.

    Only then does Mom straighten her knees and barely manages to stand up straight.

    Mom puts her hands on the table and, relying on Siwoo’s arms, was trembling all over her body.

    Icy sweat, like dewdrops, seeps out from every corner of Mom’s body as she withstands the vibration of the vibrator.

    Siwoo slightly lowers the hand that was wrapped around and supporting Mom’s pelvis to find the vibrator attached to her clitoris.

    Keureureureung!

    The vibrator, touched by Siwoo’s fingernails, made a low and threatening sound like the growl of an animal for a moment.

    “Heueut”

    Mom’s body jumps up as if startled by the sudden sound and stimulation.

    Siwoo quickly leans his body forward and suppresses Mom’s back with his chin.

    Then, Siwoo covers the vibrator, whose location he confirmed with his fingernails, with his palm.

    Juaaaaang! Juaaaaang! Juaaaaang!

    When the palm covering the vibrator is pressed down towards Mom’s crotch, a compressed vibration sound is heard wildly between her legs.

    “Haeueueuk! Haaaang! Haeueueung~!”

    Mom moaned, twisting her upper body, which was pinned down by Siwoo, from side to side in time with the vibration of the vibrator pressed against her clitoris.

    Siwoo moves the vibrator from side to side tenaciously as if determined to crush her clitoris.

    “Haaaang… Haeueung… Ma… Master… More… More… Master! Haeueuk… Haa haaaang!”

    Mom squeezes her vaginal opening as if she is about to wring out Siwoo’s penis, and makes a sound as if begging Siwoo.

    “Why? Are you going to faint here again like you do at home?! Do you think I’ll let you get away with it if you make such a fuss?!”

    Siwoo says, pressing down on Mom’s clitoris even more tenaciously with the vibrator.

    “Haeut haaang… Ma… Master… Siwoo… Master~! Heueueung….Master~! Heueuk! Haeueueung haaaaak!”

    Mom desperately calls for Siwoo, making a sound like she is about to lose her breath.

    Mom’s sobbing makes it feel as if she has acknowledged her limits and declared surrender.

    The spasms and tightening of the vaginal opening that wraps around Siwoo’s penis was informing Siwoo that Mom had reached extreme orgasms several times.

    But Siwoo does not try to stop the violation of his mother.

    “Why do you keep calling me, you fucking bitch! You just try not being able to handle it! I’m going to cancel everything I did to match your ranking with Sehee earlier, and treat you worse than my dog.”

    Siwoo, mentioning Sehee’s name and the ranking he had just determined, rebukes his mother as if threatening her.

    “I…I really…don’t think I can handle it…like this…Haeueuk…Too…too strong…! Haeut! Siwoo~! Siwoo-yat! Heueueung heugeueuk!”

    Tap tap tap!

    Mom, as if forgetting for a moment that she was playing a master-servant game, was tapping and begging on Siwoo’s arm, which was wrapped around her pelvis.

    A satisfied smile spreads across Siwoo’s face.

    With his waist stretched out while lying face down and pressing down on Mom, Siwoo brings his lips to Mom’s ear.

    Siwoo loosens the pressure on the hand that was pressing the vibrator for a moment.

    “Mom! If you can’t take it anymore, just say ‘Save me’! From now on, we’re going to set this as our family’s ‘safe word,’ okay?”

    Siwoo speaks calmly in a whispering voice, as if sharing a secret, into Mom’s ear.

    Mom’s body trembled slightly, reacting to Siwoo’s softly whispering voice.

    “Haeue… Haaaah… Heueueung… Un…”

    Mom makes a moaning sound as if she understood after hearing Siwoo’s whisper.

    After speaking, Siwoo puts strength into the vibrator again as if pressing down on her clitoris.

    Is it because she gained hope that she could be released by Siwoo at any time at her own will?

    Perhaps because she understood the story about the safe word, Mom’s violent trembling and shaking seemed to have subsided more than before, as if she had gained psychological stability.

    “Sa…Save…”

    In that state, Mom was trying to open her mouth to pronounce the safe word that Siwoo had told her.

    Siwoo lifts his waist and moves his lips to the opposite ear of Mom, and speaks as if blocking Mom’s mouth.

    “But if you say save me even though you can handle it, I won’t let you get away with it from then on, so you better be careful! You fucking bitch!”

    Siwoo warned Mom in a condescending tone and with swearing in the other ear, while maintaining the whispering voice.

    “Heueueut!”

    Mom’s body stiffens momentarily as she tries to utter the safe word.

    Mom’s vaginal opening is squeezed tightly, as if to cut off Siwoo’s penis.

    A vibration and trembling different from the vibration of the vibrator, which is vibrating at the highest level, was being created deep inside her cave.

    Mom’s appearance seems hesitant because she does not have confidence in her limits, even though there is a way to escape from the torture of pleasure pushed to the extreme.

    Siwoo left the hand pressing on Mom’s vagina as it was, and raised his waist while holding her buttocks with the other hand.

    Siwoo looks down at Mom’s appearance of enduring her limits with a contemptuous gaze.

    “Look at this! You could have handled it just now, but you were just going to say it, weren’t you? You fucking bitch!”

    Siwoo said in a cold tone, as if pointing out the deceptive attitude Mom had shown within the master-servant game he was having with her.

    Siwoo spreads his hand, which was placed on her buttocks, and gently strokes it as if caressing it, then lifts it into the air as is.

    Thwack!

    Siwoo’s palm cut through the air and fell on Mom’s buttocks.

    “Haeueueut!”

    Mom curls her body and lets out a painful groan from Siwoo’s powerful spanking.

    Thwack! Thwack! Thwack!

    Siwoo continues merciless spanking, alternating between the other buttock as if balancing them.

    “Haat! Haeueheut! Haaaat!”

    Mom is now making moaning sounds close to screams.

    Siwoo takes his hand, which was pressing down on the vibrator, away from Mom’s crotch and sends it forward.

    Siwoo grabs Mom’s arm, which was propped up on the table, and brings it to her crotch where the vibrator is attached.

    Siwoo covers Mom’s hand, which he brought to her crotch, over the vibrator, just like he had been doing earlier.

    Siwoo forcefully presses Mom’s hand, which is covering the vibrator, towards her crotch.

    Juaaaaang!

    The vibrator, pressed between Mom’s hand and crotch, once again creates a rough vibration sound and wails.

    The violent vibration is enough to be felt by Siwoo’s penis.

    “I can feel the vibrator vibrating in my dick too. Just try taking the strength out of your hand!”

    Siwoo says to Mom again as if rebuking her, and slowly takes his hand off her hand, which was covering it.

    Even after Siwoo takes his hand away, Mom’s hand pressure on the vibrator is maintained.

    “Haeut! Haeueue… Haeueueut!

    Mom was now panting with exhaustion, burying her face on the table.

    Mom’s big, shapely buttocks, swollen like a red full moon, are facing Siwoo.

    Siwoo brings his fingers, raised, to Mom’s swollen buttocks.

    Siwoo writes letters on Mom’s buttocks with his raised fingers as if playing a prank.

    [Mom], [Cunt] [Seyeong], [Sex], [Pregnancy]

    Siwoo immediately writes down the letters of the two-character words that come to mind, alternating between the left and right buttocks, one by one, as if catching and listing them on Mom’s buttocks.

    The letters are engraved, drawing white lines on Mom’s red flesh.

    Each time a word is completed, Mom trembles and lets out a breath that seems to have a deep story.

    Siwoo puts all the letters down and then wraps both hands around Mom’s waist.

    Siwoo pulls his waist back as is, and then forcefully shoves his penis into Mom’s vaginal opening.

    Cheolpueok!

    Siwoo inserts his penis deep into Mom’s vaginal opening and fixes it.
