Chapter 418 (Mom)

"How are you feeling now? Are you okay?"
Si-woo asked in a tender voice, as if genuinely concerned about his mother’s mood and physical condition.
"...Yes... I-I'm okay..."
Mom replied with a troubled expression, using awkward informal speech as if trying to match Si-woo’s tone.
Si-woo’s hand, which had been stroking the side of her breast, expanded its reach to her armpit, back, and shoulder, caressing her softly.
Every time Si-woo’s touch brushed against her naked skin, Mom’s muscles tensed, and she shuddered uncontrollably.
"Aren't you cold? You've been shivering for a while now."
Si-woo asked in a probing tone, even though he knew perfectly well that her trembling was caused by his touch.
"It... it’s not that cold... It’s... just... a little..."
Mom answered, acutely aware of Si-woo’s hand as it continued to stroke her.
"Really? I guess it’s bearable then. Then, unless something happens, you can just stay naked like this from now on, right?"
Si-woo spoke in a cocky, mocking tone, teasing her.
"Ah... no, it’s not that..."
Mom replied, shrinking back even further as if intimidated.
"Si-woo! But where did you put my clothes? Did you put them in your bag?"
Fearing that Si-woo might order her never to wear clothes again, Mom looked at the bag he was carrying and spoke with a desperate, urgent expression.
"No? Your clothes aren't in the bag."
Si-woo turned the bag inside out to show her, confirming that he didn't have her clothes.
Mom’s expression stiffened as a chilling realization washed over her.
"Th-then... where... are my clothes?"
Mom asked cautiously, looking at Si-woo with trembling eyes.
"Oh, I threw them away when I went to the bathroom earlier. Why?"
Si-woo informed her that he had discarded the clothes she had been wearing in a calm, brazen tone, as if wondering why she would even ask such a thing.
"What?! What did you say?!"
Mom’s eyes widened in shock at Si-woo’s words.
"I said I threw them away because I didn't think you'd need clothes anymore~!!"
Si-woo spoke with a slick, nonchalant attitude, as if he had simply done something perfectly natural.
"Wh... where?!"
Mom asked him urgently, her face filled with despair as if she were about to burst into tears.
"What are you going to do if you know? It’s not like you can go get them right now anyway. If you're going to go get them, let me know~"
Si-woo spoke in a rebuking tone, as if mocking her for not properly grasping her current situation.
Mom stared at Si-woo, her mouth agape and her wide eyes blinking as if she were at a loss for words.
Eventually, as if finally giving up on the last shred of hope, she closed her eyes tightly and hung her head low.
Si-woo picked up his smartphone and opened the vibrator control app.
He turned the vibration intensity up to level 3.
The vibrator attached to Mom’s groin and the smartphone in Si-woo’s hand began to vibrate violently in unison.
"Haaa... hng... h-hng... hng... haaa..."
Mom’s breathing began to grow ragged.
Si-woo moved the hand that had been stroking her back down to her lower waist, near the pelvic area of her buttocks.
The vibration of the vibrator resonated through her bones.
Feeling that vibration, Si-woo pressed down firmly on her pelvis.
Then, just as her pelvis began to twist and buck, he pulled his hand away and gently placed it on top of her head.
Si-woo’s hand now moved softly through Mom’s fine hair.
"Seon-mi!?"
This time, Si-woo called her name while stroking her hair.
"Haaaaa..."
She let out a long, sobbing sigh, as if the moment she had been dreading had finally arrived.
Her entire body trembled as if she were truly accepting the sadistic master-slave relationship with her son, which had now become an absolute reality.
"Ha... yes... Mas... Master... hng..."
Then, in a heavily trembling voice, Mom answered him, calling him Master.
Si-woo lowered the hand that had been stroking her head back to the side of her breast.
"How do you feel now? Are you okay?"
Si-woo repeated the exact same question he had asked just moments ago.
"Pardon? Yes... I-I'm okay..."
Mom continued to answer Si-woo using formal speech.
It was a strange and bizarre exchange between Mom and Si-woo, as if they were confirming to each other that they could cross between the relationship of mother and son and the relationship of master and slave whenever Si-woo desired.
"Is what Seon-ju said in the group chat earlier true?"
Si-woo asked as he slid his hand under Mom’s breast.
The thick, soft flesh of her crushed breast filled Si-woo’s palm.
"Pardon? Wh... what are you talking about? Hng...!"
Mom questioned him back as a slave, her body shrinking in tension.
"You, Seon-mi! That you like getting your ass slapped while a cock is buried in your back! Is that true?"
Si-woo repeated Aunt Seon-ju’s words from the group chat almost verbatim.
"No... that, that’s..."
Mom stammered, unable to give a clear answer, looking flustered.
"That’s what?!"
Si-woo mimicked her words overbearingly, as if pressing her for an answer.
"That... haaa... well... that is... Seon-ju... haaa... h-here... I mean... hng..."
Mom fumbled for words, dodging the question and failing to give a proper answer.
Si-woo moved the hand he had slid under her breast upward, gripping one of her breasts as if to envelop it entirely.
Then, using his thumb and forefinger, he found and pinched Mom’s firmly erect nipple.
Si-woo half-rose from his seat and brought his lips to Mom’s ear.
While gently rubbing her protruding nipple with his thumb and forefinger, he spoke to her in a low whisper.
"You have to be honest, Mom! That way I’ll know for sure if I can do those things to you, right?"
"I told you before, didn't I? I wouldn't have been like this from the start if it was something you hated...!"
"You're a total masochist, aren't you, Mom? You must be used to this since you've done it a lot with Dad, right?! You like being treated like this by your son, don't you?"
"Just tell me if you like it or hate it! I'll take care of the rest!"
This time, Si-woo referred to her as "Mom" instead of her name, whispering as if asking for her innermost feelings.
"Hng... uuuu... hng..."
Mom trembled violently as she received soft and stimulating foreplay on her erect nipple along with Si-woo’s secret whispering.
Si-woo pulled his lips away from her ear and sat back down in his original position.
He stopped rubbing her nipple and watched her distorted face in silence, as if waiting for her answer.
A moment later, as if Mom had reached a small orgasm just from Si-woo’s gaze, her body bucked and twitched.
"Hng, h-hng, hah, ha-ah!"
With her mouth open and a dazed expression, Mom let out short, repeated moans.
"Answer me! You fucking pussy-bitch! How long are you going to make me wait?!"
Si-woo returned to being a violent and stern Master, snapping at her.
"I... I think I... like it. Master... haaa... hng..."
Without even a moment to enjoy or feel the afterglow of her small climax, Mom spoke as if reacting reflexively to Si-woo’s harsh voice.
"If you like it, you like it. What do you mean you 'think' you like it?! You think you're playing games with me, you bitch?!"
Si-woo squeezed the palm that was cupping her breast hard, shouting at her once more.
"Hah! I... I like it! I like it! Master...!"
Mom answered as if confessing her true feelings, accompanied by a pained moan.
"What?! What do you like?!"
Si-woo didn't stop there; he squeezed her breast even harder and induced her to say the specific words from his question with her own mouth.
"P-pardon?"
Mom reacted as if she didn't immediately understand his question.
"I'm asking what you like, you bird-brained bitch! Say it yourself! Do I have to explain everything to you two or three times?"
Si-woo raised his voice, rebuking the flustered Mom.
"Hng... hng..."
Only then, as if realizing what Si-woo wanted, Mom let out a low, humiliating moan.
"Getting... getting f-fucked from behind... and getting my butt slapped with a palm... hng..."
Mom answered exactly as Si-woo wanted, as if she had laid down all her authority as a mother.
Hearing her answer, Si-woo loosened the grip on her breast.
Then, he flattened his palm and gently stroked her breast as if soothing a sore spot.
Mom twitched as she endured Si-woo’s palm stroking her sensitive body.
As if finding her reaction amusing, Si-woo stroked her breast for a while before pulling his hand out from between the shopping basket and her arm.
Then, he immediately lifted his top and lowered his pants, revealing his penis, which had swollen as large as it could possibly get, right in front of her.
Mom’s dazed gaze was drawn toward Si-woo’s rock-hard erection.
