Chapter 429 (Mom)

[Okay... I’ll do that.]
As expected, an affirmative answer comes back from Mom.
[But I’d prefer if you didn’t show Se-young us having sex...]
After agreeing to the play, Mom adds a conditional clause at the end.
Si-woo ponders for a moment, then a smirk spreads across his face as if a brilliant idea has just struck him.
[Fine. I won't let Se-young see us having sex!]
Si-woo readily accepts Mom’s condition.
The two continued their negotiation, meticulously going over the rules of the lewd play they were conducting within the family, as if reorganizing them.
Si-woo felt as if he were crafting detailed clauses to be added to Mom’s Slave Contract, adjusting them to fit their mutual circumstances.
As he scrolled back through the 1:1 chat window with Mom, Si-woo’s penis grew harder and more strained than ever before.
* * *
[Are those two things enough?]
Mom asked, seemingly wanting to finalize the agreement on the rules of the play they were engaged in.
Si-woo hesitated for a moment before typing back.
[No, just one more thing!]
He replied as if there were one last master-slave play he needed to request from her.
[What is it? Tell me.]
Mom seemed to have grown quite accustomed to negotiating Si-woo’s requests and rules within the 1:1 chat window.
[You know about the initial tattoo on Se-hee’s thigh, the one she got with her friends recently, right?]
Si-woo began to bring up the tattoo engraved between Se-hee Noona’s thighs.
[Yeah... I know. You sent me a photo before. I’m aware of it... but why bring that up all of a sudden?]
Mom asked cautiously, her reply suggesting she had a vague inkling of what Si-woo was about to demand.
[That was a group couple tattoo she got when she went out with her friends. Se-hee paired up with Shin-bi, and they tattooed each other’s initials on their inner thighs.]
[Se-hee and Shin-bi aren't exactly dating, but it seems they’ve been in a deep lesbian relationship for a long time!]
[When I first saw it, I was incredibly annoyed, but thinking about it later, I realized it’s actually a relief... since the partner isn't a guy...]
Si-woo explained everything—Se-hee Noona’s tattoo, her relationship with Shin-bi Noona, and his feelings at the time—as if laying it all bare to Mom.
[I see...]
Mom reacted without any sign of surprise at Si-woo’s message.
Did Mom already have a general idea about Se-hee Noona’s tendencies and her relationships with her friends?
In truth... considering Se-hee Noona’s past behavior and everything Mom had experienced up until today, it probably wasn't that shocking.
[Before I got your text and came out to meet you, I had sex with So-ra and Shin-bi too! You saw Se-hee’s friends who came over today, right?]
Si-woo suddenly confessed to having sex with Se-hee Noona’s friends at home as if it were nothing.
Mom didn't respond for a moment, seemingly flustered and shocked by the revelation that he had slept with Shin-bi Noona’s friends.
[Mom?!]
Si-woo called out, forcing a reply from the silent Mom.
[Yes... you did?]
Mom finally reacted to Si-woo’s call.
[Yeah... I did it with So-ra in your room and with Shin-bi in Se-jin Noona’s room, separately. Se-young was in the shower at the time...]
Si-woo reported the details of the situation where he had sex with Se-hee Noona’s friends.
[What about Se-hee? Was she with you?]
Mom asked, curious about how Se-hee Noona was involved at the time.
[No, I told Se-hee to just stay in the living room with her clothes off. I had sex with her friends one by one in separate rooms.]
Si-woo answered Mom’s question in detail.
[...Is that so?]
Mom responded hesitantly, as if she were lost in thought over the detailed story.
[I pounded both So-ra and Shin-bi half to death with my cock. I think I can claim them as my property now. You know what I mean, right?]
Si-woo hinted to Mom that both So-ra Noona and Shin-bi Noona were now tied to a Slave Contract.
[Yes... I know...]
Mom replied as if she understood the implications without needing a detailed explanation.
[As a mark that those bitches are my slaves, I’m planning to have my initials tattooed on their thighs, just like the ones Se-hee and those girls have now! Since I can't erase the ones already on the other side!]
Si-woo explained his plan to Mom.
He believed that in a master-slave relationship—especially with slaves who already had experience with tattoos—it was a command that could easily be accepted.
[...I see...]
Mom replied, her words heavy with an ominous intuition.
[So... what do you want me to do?]
She immediately followed up with a question, adopting the attitude of a faithful servant.
[Take Se-hee and get my initials tattooed on her thigh! Se-hee will know where the tattoo shop is.]
Si-woo explained the task Mom needed to perform with Se-hee Noona.
[But have you talked to Se-hee about tattooing your name on her thigh?]
Mom asked, sounding worried that she might have to force Se-hee Noona into something she didn't want.
[Yeah, I’ve mentioned tattooing my initials several times, so Se-hee should understand well enough.]
Si-woo replied instantly to reassure Mom.
[So I just have to take Se-hee and get the tattoo done?]
Mom asked, as if confirming Si-woo’s instructions one last time.
It seemed Mom had made up her mind to take Se-hee Noona and have Si-woo’s initials engraved on her thigh as ordered.
Seeing Mom’s message on the chat screen, Si-woo now wore a triumphant smile.
[Yeah! Just get Se-hee tattooed! And while you’re at it, Mom, you get one too! My English initials in the same spot...]
Si-woo slyly slipped in the demand for Mom to get his initials tattooed as well.
A mother who had resolved to tattoo her son’s initials onto her daughter’s thigh—a daughter who had become a slave by the command of the son who had become their master...
There was no way such a mother could refuse the command to have those same initials engraved on her own thigh.
That very ominous intuition turned into a hardship of reality, weighing heavily on Mom’s heart.
[Mom?]
Si-woo called out again when Mom didn't reply.
[Yes?]
Mom responded reflexively to Si-woo’s call.
[I know it’s a lot to ask, but can you do this for me?]
Si-woo demanded an answer to his irresistible command.
Mom stalled for a moment as if agonizing over it.
[You want me to go with Se-hee and have your initials tattooed on my inner thigh too?]
After a moment, Mom asked as if confirming Si-woo’s instructions for the last time.
[Yeah! I want my initials, SWY, tattooed right under Na Seon-mi’s pussy hole! Because it’s the mark of my slave!]
Si-woo conveyed his desire to Mom firmly and precisely.
And this time, he didn't call her "Mom," but used her name instead.
In the 1:1 chat window where they had agreed to act as mother and son, Mom seemed to have lost her words again at Si-woo’s provocative demand and tone.
This time, Si-woo didn't rush her and waited for her answer until the end.
The noise echoing from the karaoke corridor felt unrealistically distorted.
And after a short wait, Mom’s reply appeared in the chat window.
[Yes, Master. I will do everything as you say.]
Mom answered Si-woo submissively, as a slave.
Si-woo felt as though he had finally, completely broken Mom into submission, even within the 1:1 chat window.
Si-woo’s penis throbbed, engorged to the point it felt like it might burst.
[Good! Then I’m coming over now, so wait right there. Mom!]
Si-woo spoke as if concluding the conversation, calling her "Mom" once again.
As if to keep his promise to return her to being "Mom" once the play was over...
Si-woo picked up the wet wipes he’d gotten from the vending machine along with the mop and headed toward the room where Mom was.
* * *
"You're going to have to get a wax later!"
As soon as he entered the room, Si-woo spoke in a casual, passing tone, noticing the hair peeking out from the red micro bikini swimsuit covering Mom’s lower abdomen as she sat in the corner.
Her body was clad in the red micro bikini swimsuit Si-woo had brought.
Her shapely, voluminous breasts were barely covered, and the pale skin of her buttocks spilled out from the tiny red fabric, exposed to the air.
Mom’s face was flushed a much deeper crimson than when she had been completely naked and having sex with Si-woo earlier.
