Chapter 411 (Mom)

"But really, there's nothing we can do about it right now, is there? What should I do? How do you want me to handle this?"
Si-woo asked his mother, his voice dripping with a mockingly sympathetic tone.
After a moment of seemingly trying to organize her thoughts, his mother spoke.
"First of all, keep all the promises you made to me before! It doesn't matter whether Se-young knows or not!"
She spoke to Si-woo in a firm, resolute voice.
"You must use a condom when you do it! I won't say anything about when you're with Gyu-ri or Seon-ju. But when you're with Se-hee and Se-young, you must stick to it!"
She spoke with such determination and resolve that it seemed contraception was the one thing she would never compromise on.
"What about when I have sex with you, Seon-mi?"
Si-woo asked, as if intentionally poking a hole in her logic.
"O-of course you have to then, too!"
His mother’s voice rose slightly, sounding flustered. At this point, she didn't even try to suggest they wouldn't be having sex.
"But now that I think about it, I've done it bare with Gyu-ri, Seon-ju, and Se-hee at least once, and I've even come inside them! But I've never put my bare cock inside you or Se-young, have I? If we follow the promise we just made, that means I can never do it bare for the rest of my life, right?"
Si-woo stroked his penis, speaking to his mother as if he were deeply disappointed.
"I... I'm having Se-young take... birth control pills... so just... be patient for a little while... until the medicine takes effect...!"
His mother offered these words as if to provide some small comfort to the disappointed Si-woo.
Si-woo’s mind went a bit blank at the revelation that she was giving Se-young birth control pills.
"You're giving her birth control? To Se-young too? Since when?"
Si-woo asked, just to be sure.
"It's... been about... a week... She still needs to take them for about four more weeks..."
His mother lowered her eyes slightly and answered shyly, looking like someone caught in a shameful act that should never be revealed to others.
A week ago—that was when his mother had taken Se-young and run away to Aunt Seon-ju's house.
Had she already anticipated back then that everyone in the family, including Se-young, would end up having sex with her son, Si-woo?
Even before their full-scale master-slave play had begun, his mother had been preparing for sex with him.
"Are you taking birth control too, Mom? Along with Se-young?"
Si-woo asked, seeking confirmation.
Avoiding his gaze, his mother gave a vague nod.
During that week she had spent away with Se-young, she had been preparing for sex with Si-woo.
Slap, slap, slap, slap, slap!
Si-woo’s hand moved rapidly, reflecting his rising excitement.
"So in four weeks, I can come inside you and Se-young?"
Si-woo spoke with a hint of joy in his elevated voice.
"Try to do it outside if you can! Regardless, you have to wait until the pills are fully effective!"
His mother turned back toward Si-woo, speaking as if this was one point she wouldn't back down on.
"Alright~ I just have to wait four weeks, right?"
Si-woo switched hands as he continued to shake his penis and spoke to her.
"If I do it ten times a day, that's 280 times in four weeks, right? If I'm going to rotate between you, Se-hee, and Se-young like that, I'd better buy a lot of condoms in advance. Don't you think?"
Si-woo calculated the number of condoms he would need for the next four weeks, sounding quite amused.
"Hauuuuu..."
A hot sigh escaped his mother at Si-woo’s words, which felt like he was mocking her...
The vibration of the smartphone he had placed on the table continued incessantly.
* * *
"I'll stop calling you by your name in the 1:1 chat room and treat you properly as a mother!"
"Whether Se-young knows or not, we'll act like normal at home during the day when she's awake!"
"And for the next four weeks, I'll definitely use protection when I'm with you, Se-hee, and Se-young, right?"
Si-woo recited the points his mother had made one by one, folding his fingers as if summarizing them.
"Y-yes... those are all things you promised me before!"
His mother answered in a trembling voice, as if she were once again feeling the intense stimulation of the vibrator attached below.
"Is that all it takes?"
Si-woo asked for confirmation, acting as if it were no big deal.
"P-pretend you don't know about me and Se-hee! I'll pretend I don't know what you guys are doing, too!"
His mother was demanding a daily life of blatant pretense and deception for every member of the family.
"Yeah~ is that all?"
Si-woo pulled his back away from the wall and straightened his posture, asking her once more for confirmation.
"A-and what I said in the text earlier! Put... me and Se-hee... back to the way we were... I can't keep living while using formal speech with Se-hee!"
His mother was asking Si-woo to restore the family hierarchy that had been flipped with Se-hee Noona.
Seeing Si-woo straighten his back, she continued hurriedly, as if realizing that the time they had to talk as mother and son was running out.
Si-woo didn't answer her immediately; instead, he pulled one foot up onto the chair.
In a half-standing posture with his knee supported by the chair, Si-woo thrust his pelvis forward.
His massive penis was thrust imperiously right in front of his mother's face.
"I'm talking about Se-hee and me! Put us back... as mother and daughter! How can we keep doing that all day? Don't we have lives to live?"
Was she flustered by Si-woo’s penis being thrust in her face, shaking violently up and down?
His mother squeezed out her voice, desperately repeating the same demand once more.
"Mom is... d-doing everything you and Se-hee tell me to do! ...I think I've been punished enough!... I-I'm reflecting on what I did, so..."
In a submissive attitude, as if she were subordinate to Si-woo, she explained her desperate situation and asked for his permission.
She spoke with such desperation, as if every rule and regulation in the house was determined by a single word from Si-woo.
Looking at her like that, a sadistic desire seemed to boil up inside him.
"Alright~ is that all you need?"
Si-woo looked down at her, speaking with an attitude that suggested he was barely listening.
"F-for now..."
His mother answered as if she still had more to say, but had at least gotten the most urgent matters out.
"If I keep going a little longer, I think I'm going to come on your face and clothes, Seon-mi! If you don't want to get your clothes dirty, just keep my cock in your mouth for now!"
Si-woo commanded, bringing the massive, heated hunk of flesh to her lips.
"Hauuuuuu~"
His mother let out a hot breath and trembled slightly at his words.
She glanced toward the door for a moment, as if worried about the outside.
Si-woo placed a hand on her head as if telling her to focus on him.
Her gaze shifted back to Si-woo’s magnificent penis.
Si-woo pushed the tip of his penis into her mouth.
His mother slowly closed her eyes and parted her lips as the penis advanced.
"Hauuuup!"
The warm, wet sensation of the inside of her mouth enveloped Si-woo’s penis.
Si-woo thrust his penis all the way to the back of her throat before pulling his hips back slightly.
With her eyes tightly shut, his mother struggled to hold his hard member, which filled her mouth to capacity.
Si-woo let go of his penis and picked up the smartphone from the table.
Then, he turned the vibrator's intensity up one or two levels.
Bzzzzzzzzzt!
The buzzing sound intensified simultaneously from his mother's groin and the smartphone.
"Haaaah-mmm!"
With his member still in her mouth, his mother groaned as she curled her body inward, trying to endure the intensifying vibration.
Si-woo switched the smartphone screen from the vibrator control to the camera app.
Ding!
Si-woo began recording a video of his mother’s seductive face looking up at him.
He took his hand off her head and tapped her cheek with his fingertips as if striking her.
Tap, tap!
"Seon-mi, you have to look at me! We're not done talking yet! How can you close your eyes like you're enjoying it so much, just because you're distracted by the vibrator?"
Si-woo spoke after unpleasantly poking her cheek, as if telling her to snap out of it.
"Uuup, hauup!"
A humiliating groan leaked from his mother’s mouth as she held his penis.
Her startled, frowning expression soon softened.
Her eyelids fluttered open.
Si-woo placed his hand back on her head, cupping it.
With his penis still in her mouth, his mother looked up and met his eyes.
"I'll try my best to keep the promises we made at first~!"
Si-woo spoke as he slowly moved his penis back and forth inside her mouth.
The soft sensation of the inside of her mouth rubbing against his penis was incredibly stimulating.
"I'm not supposed to call you by your name in the 1:1 chat room and I have to treat you properly as a mother, right?"
"And I have to use condoms when I have sex with the family until the birth control pills take effect!"
"Finally, we're going to act like normal during the day when Se-young is awake? Including pretending we don't know anything when we're all together, even if Se-young and I have sex separately where you can't see us?"
Si-woo was detailing the contents of their conversation as if explaining it to a third party beyond the video being captured on his smartphone, rather than to his mother herself.
His mother blinked while keeping his penis in her mouth, as if affirming that what he said was correct.
