    (Se-jin’s Sister)

    396

    As the text message arrival notification sounds, Si-woo’s penis, which is held in Se-hee’s mouth, twitches with strength.

    Si-woo immediately touches the smartphone screen to check the message that was just sent.

    [Si-woo, come out now!]

    In the chat window, a message from Mom arrived, telling Si-woo to come out without any explanation.

    She never reacted even when I talked to her like that… As soon as she saw the oral photo of Se-hee sucking my penis…

    Was Mom imagining the condomless sex between Si-woo and Se-hee that would follow?

    Si-woo begins to feel a little resentful towards Mom.

    However, the fact that Mom, who hadn’t replied properly until now, sent Si-woo a message again, made him feel even more delighted.

    [Mom, where are you now?]

    Si-woo immediately asks where Mom is.

    [The mart near the station!]

    Mom simply answers Si-woo’s question.

    The mart near the station was a familiar place that Si-woo often visited.

    Perhaps because he felt relieved after confirming where Mom was, Si-woo suddenly feels like teasing her and playing a prank.

    [But I’m a little busy right now? Didn’t you see the Se-hee photo I sent a little while ago? I’m in the middle of doing it? Se-young will be out of the shower soon too…]

    [The mart near the station is close from here, right? Can’t Mom just come home? If Mom walks slowly now, I think the order will be perfect after Se-young? Hehe]

    Si-woo mentions the photo of Se-hee giving him oral sex and Se-young being in the shower, and then sends a reply to Mom as if he’s showing off and teasing her.

    Mom seemed to hesitate for a moment at Si-woo’s bold and mischievous answer.

    Then, Mom’s text message comes to Si-woo as if she’s getting serious.

    [You can do that later! Are you going to talk to your Mom like that?]

    [Are you really not going to treat Mom like Mom now that you’ve become like this?]

    [Are you not going to listen to everything Mom says from now on?]

    Mom sends a series of messages to Si-woo as if she’s cornered with no place to retreat.

    Si-woo is slightly puzzled and embarrassed by Mom’s sudden serious reaction.

    [No, it’s not like that…]

    Si-woo carefully answers, trying to gauge Mom’s mood.

    [Mom has something to tell you, Si-woo, so come out to the mart in front of the station now! It’s important!]

    Mom was telling Si-woo to come to the mart again as if she had made a desperate decision.

    [Okay. I’ll go. I can go right now, right?]

    Si-woo was asking as if he was overwhelmed by Mom’s force, or worried about Mom’s condition.

    [Come quickly!]

    Mom’s last message to Si-woo was like a scolding.

    It was a conversation between two people as if the power dynamic had been reversed.

    However, Si-woo didn’t feel any unpleasant or displeased feelings about Mom’s attitude at all.

    Rather, with a sense of anticipation for some reason, Si-woo’s penis swells even larger in Se-hee’s mouth.

    [Okay~ I’ll get dressed and leave right now!]

    Si-woo answers Mom’s message while slowly rubbing his penis, which is full in Se-hee’s mouth, back and forth.

    What does Mom want to talk about separately with Si-woo now?

    In fact, after having sex with Mom, almost all of their conversations have been fragmented chats.

    Mom, who started with Si-woo’s forced pleas and nagging, was treating Si-woo as her master in the chat.

    Mom even answered Si-woo’s orders in polite language in the group chat room with Aunt Seon-joo and Se-hee, and even sent lewd photos according to Si-woo’s orders.

    However, as she watched the process of such a relationship with Si-woo affecting and continuing into reality, Mom seemed to be feeling embarrassed and perplexed.

    Therefore, she tried even harder to clearly distinguish between the attitude towards Si-woo in the chat as a slave and the attitude towards Si-woo as his actual Mom.

    While frequently reminding herself that the master-slave relationship with Si-woo was an agreed-upon game, Mom always emphasized that she should be able to return to the original mother-son relationship at any time.

    That is like an absolute prerequisite for Mom to have a master-slave relationship with Si-woo.

    But now, not only herself, but also Aunt Seon-joo and Se-hee, and even Se-young and Soo-ah, who were almost the last line of defense, have developed a master-slave relationship with Si-woo.

    Now that Mom’s absolute prerequisite for having a master-slave relationship with Si-woo has been broken…

    Mom may be realizing that the master-slave relationship with Si-woo, which has been established with other family members as well, cannot be reversed as before.

    Si-woo recalls the mouth sensations of the three mothers and daughters, which he has experienced at least once each.

    The thought of being able to taste the sensation of the three people’s tongues with his penis at the same time, not as a game but as an actual sensation, makes him feel a euphoric and overwhelming pleasure that pierces through Si-woo’s spinal cord.

    “I think I need to go out for a bit! Seon-mi said she has something to talk about and told me to come out?”

    Si-woo says to Se-hee, who is sucking his penis, bringing the chat window with Mom in front of her.

    Se-hee, who is sucking Si-woo’s penis in her mouth, reads the chat window screen that Si-woo is showing.

    After reading all the messages on the screen, Se-hee looks up at Si-woo and loosens her lips and mouth as if she understands.

    Si-woo grabs Se-hee’s head and slowly pulls his penis out of her loosened mouth.

    Si-woo’s penis slides out of Se-hee’s mouth like a snake crawling out.

    “Hoo-ooo-oop pua!”

    The end of Si-woo’s huge pillar that was pulled out of Se-hee’s mouth bounces up to the ceiling like a spring.

    Se-hee’s thick saliva, which was thickly applied to the penis, splashed on her face.

    Si-woo brings his penis pillar to Se-hee’s face.

    Si-woo wipes his penis, which is covered in moist saliva, on Se-hee’s face.

    “Mom must have really gone grocery shopping at the mart~ She’s telling me to come to the mart in front of the station now?”

    “I’m going to go talk to Mom and come back, so clean up here while I’m gone! Got it?”

    Si-woo says, applying the saliva that’s all over his penis to every corner of Se-hee’s face.

    “Yeah…I…I’ll clean it up…”

    Se-hee answers, giving her face widely to Si-woo’s penis, which is covered with saliva and waste.

    Se-hee’s bare face and hair were being evenly dirtied with the waste from the penis.

    “I need to go to my room and change clothes. Just wash the clothes I took off in Se-jin’s room! Se-hee, put my clothes in the dressing room!”

    Si-woo says, looking straight into her eyes while holding his penis to Se-hee’s face.

    “Yeah…Haa…I’ll…put that away too.”

    Se-hee breathes roughly and answers Si-woo obediently.

    -Tak! Tak!

    Si-woo swings his huge penis pillar up and down, hitting her face as if bouncing it.

    “Heut!”

    Despite Si-woo’s humiliating actions, Se-hee closes her eyes tightly and only groans, not avoiding the face she was holding up.

    Si-woo glances up and looks around the master bedroom and Se-jin’s room.

    Where Sora and Shin-bi are lying unconscious after experiencing climax from Si-woo’s pounding.

    And he also glanced at the shower room where the sound of water had stopped.

    Si-woo suddenly worried that the sisters who had fainted might wake up while he was away and do something absurd to Se-young.

    However, Shin-bi and Sora, who appealed their existence to Si-woo with the thought of having their hymens pierced and tried to confirm Si-woo’s intentions, didn’t seem like they would do such a thing now.

    “I’ll be back soon with Mom. Wait with Se-young!”

    Si-woo says, taking his penis off Se-hee’s face.

    “If anything happens to Se-young while I’m gone… Just know that it won’t end with fainting then!!”

    Si-woo tells Se-hee as if delivering a warning to her two friends, as if taking out insurance against a possible event.

    “Yeah…I’ll tell Shin-bi and Sora. Don’t…don’t worry about that…”

    Se-hee nods and answers Si-woo as if making a promise.

    Si-woo gently strokes Se-hee’s head.

    “Ah! And I think I have a vibrator charging in Se-young’s room right now! While I go to my room to change clothes, can you bring the vibrator from Se-young’s room? Put it on the table over there!”

    Si-woo, who was stroking Se-hee’s head, suddenly orders her as if he remembered something.

    Se-hee, perhaps understanding that it was an order to bring the vibrator that would be used on Mom, nods her head greatly once, blushing.
