Chapter 399 (Mom)

The room Si-woo entered with his mother was just large enough for two people to use comfortably.
A karaoke machine stood directly in front of them, with a small table beside it for tambourines and songbooks. The seating was an L-shaped bench that wrapped from the wall by the entrance to the side wall.
A dark, tinted film had been applied to the large glass door, allowing people to see out, but making it difficult to see in. However, if someone looked closely enough through the glass, they could still make out what was happening inside.
His mother went in first and took a seat in the corner, facing the karaoke monitor. Si-woo followed her in and sat down near the door.
He placed the grocery bag and shopping bag on the floor by his feet and set his backpack on the seat beside him. As soon as the bag was out of the way, Si-woo's cock, already fully erect, revealed its magnificent state, straining against his clothes as if it might burst through.
His mother sat there, pointedly pretending not to notice his unavoidable erection. Sitting right next to her, Si-woo could see her face was slightly flushed, as if she were a bit tipsy.
He hadn't noticed when they were standing in front of the mart, but now that he was sitting close to her, he could smell the sweet scent of alcohol on her breath. Had she bought alcohol at the mart earlier and been drinking by herself?
She sat there in silence, lost in thought. Si-woo wondered what she wanted to say to him.
"Mom, didn't you call me because you had something to talk about?"
Si-woo spoke first, prompting her. He waited for her to say anything.
His mother opened her mouth to speak but stopped. She repeated this several times, the silence stretching out awkwardly as the flow of the conversation kept breaking.
Then, as if something had just occurred to her, she finally spoke.
"There's a frozen pizza in that grocery bag. You saw the microwave in the lobby earlier, right? Go heat one up now! And take out a couple of cans of beer before you go!"
Even though the glass door allowed a clear view of the interior, she seemed uncomfortable being alone in the room with Si-woo. She kept her eyes fixed forward, avoiding his gaze as she gave him instructions.
Si-woo checked the bag and found a small pizza box and cans of beer. Had she bought the beer and instant food specifically to eat while talking to him at the karaoke bar?
If so, the amount of alcohol and snacks in the bag seemed a bit excessive. And what caught his eye more than anything were the cigarettes and the lighter. There were three different brands of cigarettes inside.
Si-woo had no memory of his mother ever smoking. Was she planning on starting?
"This one?"
Pushing his curiosity aside, Si-woo pulled the frozen pizza out of the shopping bag and held it up for her to see.
"But is it okay to eat outside food here?" he muttered to himself.
"They allow deliveries here. We just have to clean up after ourselves!"
His mother gave him a surprisingly clear answer.
"But isn't alcohol forbidden? Usually, karaoke places like this have signs saying no alcohol allowed."
Si-woo placed the beer cans on the table, sounding a bit concerned.
Only then did his mother look at him with bleary, resentful eyes.
"Who cares! It's not like the owner is watching us all day! Stop grumbling and just go!"
She spoke with a hint of irritation.
"Alright, alright... but why have you been so annoyed with me lately?" Si-woo asked, acting as if he were being treated unfairly.
His mother whipped her head around to glare at him.
"I just need to heat this for about five minutes, right?"
Si-woo spoke playfully, avoiding her gaze as he took the pizza and headed out to the main hall of the karaoke bar.
"Haaah...!"
As he left the room, he heard a heavy, suppressed sigh escape his mother's lips.
As if reacting to that sigh, Si-woo's cock throbbed and grew even harder.
Reaching the main hall near the entrance, Si-woo placed the pizza in the microwave. He set the timer for five minutes and started it.
On his way from the room to the hall, he had glimpsed two or three groups of female students through the glass doors, looking like they were from an intermediate or Advanced Academy.
His cock was bulging so prominently it looked like it would tear through his pants, but Si-woo made no effort to hide it. Part of it was because he didn't think the girls inside, who were busy singing their hearts out, would care about someone passing by.
But more than that, he felt as though, in this moment, everyone in the building would understand his situation.
As the microwave ran, Si-woo looked around. Aside from the entrance, the hallway, the snack counter, and the kiosk, there were no CCTV cameras pointed elsewhere.
Where Si-woo stood in front of the microwave was a complete blind spot.
A crazy thought suddenly flashed through Si-woo’s mind.
What if I took my cock out and masturbated right here?
What if I showed it to Mom, who’s waiting alone in the room, via video?
After a brief moment of hesitation, Si-woo pulled his cock out of his pants. His massive, erect cock stood tall, pointing toward the empty space of the main hall.
Beep!
He opened the camera app on his smartphone and began recording his cock. Si-woo wrapped one hand around his massive, imposing cock and began to stroke it slowly.
The sight of his huge cock being rubbed up and down was captured on his phone.
In the open space of the karaoke bar, in a precarious situation where he could be caught at any moment, Si-woo felt a powerful surge of deviant satisfaction and euphoria.
The sound of the karaoke accompaniment and the provocative singing of the female students echoed from the rooms. The knowledge that his mother was waiting for him in a room at the end of the hallway...
Everything seemed perfectly calculated to fuel Si-woo's arousal.
Slap! Slap! Slap! Slap! Slap!
While the pizza rotated in the microwave, Si-woo stroked his massive cock into the air with a heart-pounding thrill.
Ding!
The microwave signaled it was finished.
Beep!
Si-woo stopped his hand and ended the recording. He saved the video and sent it directly to his mother.
The four-minute-long video was uploaded to their chat window.
Si-woo pulled up his pants and took the heated pizza out of the microwave. The number '1' next to the video in the chat window vanished instantly.
As expected, there was no reply.
To give his mother enough time to watch the video, Si-woo sat on a chair in the main hall and scrolled through their past conversations and photos.

About five minutes later, Si-woo returned to the room with the pizza.
While he was gone, his mother had already opened a second can of beer and was gulping it down.
"You should've waited to eat it with the pizza. What's the rush?"
Si-woo spoke innocently as he placed the pizza on the table, as if the deviant act he had just performed in the main hall had never happened.
Seeing his mother's flushed face and her silence, Si-woo returned to his seat.
Perhaps feeling pressured by the gaze of her son, who had just finished masturbating, she set down her can and walked over to the karaoke machine.
She tapped a card—likely one issued by the shop—on the payment terminal, then grabbed the microphone and remote before sitting back down.
Her hurried movements suggested she was agitated after seeing the video Si-woo had sent. Had she never imagined that Si-woo would commit such a perverted act even in a place like a karaoke bar, which she thought would be safe?
Even though she had clung to him the night before, wailing and calling him "Master" and "Honey"...
Even though she had spoken to him pleadingly this morning with his cock in her throat...
Was she now trying to revert to being "Mom" and deny everything that had happened?
Si-woo watched with amusement as his mother, who he thought would say something the moment he entered, moved about busily in silence. The longer it lasted, the more blood seemed to rush to his member.
Unable to bear it any longer, his mother hurriedly punched a song number into the remote. She reserved three songs in a row.
The lights dimmed to a darker hue, and the disco ball began to spin dazzlingly. A familiar melody started to flow from the machine.
It was a popular song from when his mother was young—songs about travel, youth, or love.
Avoiding Si-woo's gaze, his mother stood up and began to sing. From where Si-woo sat, he had a perfect view of her backside swaying to the music.
Her hips, hidden beneath the hem of her T-shirt, swayed just an arm's reach away.
