    “…Uh… I think I need to stop by the restroom before going to the department store. But, I need to go to the convenience store right after getting off…”

    Su-ah trails off her answer as if she understands why Si-woo brought up the restroom.

    “How about Se-yeong? Is it okay if you don’t go to the restroom with Su-ah?”

    Si-woo turns to Se-yeong this time, asking with concern.

    “Yeah~ I have to go too~! Because of oppa… Hehe~!”

    Se-yeong touches her slightly damp hair as if gathering it with her thumb and forefinger, and answers Si-woo.

    Se-yeong, touching the hair that Si-woo had just smeared with filth, showing a bright expression and tone as usual.

    It wasn’t exactly a resentful tone, but it felt like a comment containing the intention to playfully tease Si-woo.

    When Si-woo saw Se-yeong’s sly and provocative appearance, he felt relieved for some reason, but also felt a warm sensation in one corner of his heart.

    “Si-woo oppa… But can you lend me your check card? I think I’ll need… wet wipes…”

    Su-ah asks Si-woo to borrow his card, thinking of buying wet wipes to wipe the contents of her bag, which was covered in semen.

    “Okay, I’ll lend you the card~ We can go into the convenience store together and buy them~!”

    Si-woo readily agrees to Su-ah’s request, as if taking responsibility for what he had done.

    “Even if we let the card and smartphone inside the bag that’s wet go, shouldn’t you buy the other things again?”

    Si-woo asks Su-ah about the state of the things in her bag, as if deliberately trying to make her more aware of it.

    “Ugh… yeah… I think I have to buy them again…”

    Su-ah answers Si-woo’s questions, which he keeps asking as if confirming, in a shy voice.

    “What else do you need? Is what I stuck down there still sticking well?”

    Si-woo now brings up the vibrator that Su-ah is wearing without hesitation.

    “Ah… I think it’s… still okay…”

    Su-ah trails off again, as if troubled by Si-woo’s continuous questions.

    “Is the battery okay? How was it when you used it with your mom yesterday? Does it last long?”

    Si-woo’s questions continue relentlessly.

    “Uh… I think I’ll have to charge it later… Because… it runs out quickly…”

    Su-ah lowers her head as she answers, as if conscious of the vibrator installed in her panties.

    “Oh, right~! Before going to the restroom and cleaning your bag with wet wipes, take a few pictures and send them to me! Because I’m going to show them to Seon-ju too.”

    Si-woo, as if suddenly remembering, was giving Su-ah instructions to take pictures of the inside of her bag, which was covered in his semen, in the restroom and send them to him.

    -Si-woo, who now seems to call Seon-ju imo’s name without any honorifics in front of Su-ah as if it’s natural-

    “I’ll take them with my phone and send them to you~! I have to show Seon-ju everything, including what oppa smeared on Su-ah’s smartphone, hehe~”

    Se-yeong says to Si-woo, holding up her smartphone and smiling brightly.

    -Following Si-woo, casually calling Seon-ju imo’s name without honorifics, as if it’s natural…-

    Su-ah, unable to say anything in response to the two siblings’ conversation, which was close to mockery and humiliation, just stood there with her head bowed.

    “Is Su-ah okay? With sending pictures to Seon-ju?”

    Si-woo asks Su-ah directly one more time, as if trying to confirm, in order to hear Su-ah’s answer on purpose.

    “Yes… it’s okay… Si-woo oppa…”

    Su-ah lifts her head and answers Si-woo with a faint smile.

    Si-woo’s hand, which now rests on Su-ah and Se-yeong’s backs without any cautiousness or hesitation.

    Si-woo strokes the outlines of the two younger sisters’ bodies from their backs to their buttocks, as if capturing them with his palms.

    Si-woo repeatedly strokes them up and down, as if trying to imprint the different but similar bodies of his two younger sisters with the sensation of his palms.

    The slightly feverish temperature and subtle muscle tremors of the younger sisters were conveyed to Si-woo’s palms as they were.

    As he thought about stuffing his thing into the small bodies of Se-yeong and Su-ah, which he felt with his palms, the thing that had been drooping started to swell up again.

    **

    An announcement was heard in the train that it had arrived at the department store station.

    Si-woo lets go of the hands that were touching his younger sisters, secures the bag he is carrying in front of him, and hides his now-gigantic penis again.

    As the train doors open, weekend passengers pour out onto the platform…

    Si-woo, together with his younger sisters, comes out of the train as if swept away by the crowd.

    Weekend outing passengers who got off the train were filling the department store platform.

    Si-woo walks forward, being careful not to get separated from his younger sisters in the slow-moving crowd.

    The faint smell of his semen wafting from his younger sisters, who are walking ahead.

    Si-woo was worried that the smell of his semen, which he had spilled in Su-ah’s bag, might spread around.

    But fortunately, the people passing by didn’t seem to notice the situation inside Su-ah’s bag.

    Even if they did notice, they wouldn’t be able to immediately suspect Si-woo and his younger sisters while they were buried in the crowd.

    The young younger sisters’ racy outfits, the lewd liquid flowing between their thighs, the filth on their hair, Si-woo’s hugely erect penis…

    Buried in the buzzing resonance and chaos among the crowded people, nothing becomes a problem.

    Si-woo and his younger sisters, who were planning to head to the convenience store as soon as they got off the train.

    But Si-woo and his younger sisters are swept away by the flow of people and pushed to walk towards the ticket gate.

    They could have broken free if they had forced it, but Si-woo didn’t.

    Se-yeong and Su-ah stand in line in front of Si-woo.

    To pass through the ticket gate, they would have to tap their transportation card on the card reader sensor…

    Su-ah had no choice but to open the zipper of her mini crossbody bag and take out the card covered in Si-woo’s semen.

    The moment she opened her bag and took out her card, the smell of Si-woo’s nighttime flower, which filled the bag, would spread around, drawing the attention of the people around her.

    A situation where she had to take out the card soaked in Si-woo’s semen and hold it over the ticket gate terminal, feeling ashamed and embarrassed, according to the flow of the irresistible crowd.

    Perhaps, before opening her bag, Su-ah would look around like a flustered person, then turn to Si-woo and make a face asking for help.

    But Si-woo had no intention of helping Su-ah in that situation.

    Si-woo is planning to completely ignore Su-ah, who is looking back, and leave her alone in the crowd, to fall into shameful and embarrassing feelings…

    Putting some distance between himself and Su-ah, Si-woo lets another person come between the two.

    Si-woo watches Su-ah from a distance, looking troubled while emitting the smell of semen, with interest.

    Just imagining the shame and isolation that Su-ah will feel makes Si-woo’s thing swell up again as if it will burst.

    Se-yeong passes through the ticket gate and goes out, and now it’s Su-ah’s turn.

    Si-woo waits with an excited heart for Su-ah’s bag to open.

    Si-woo was hoping that Su-ah would quickly take out the card that smelled strongly of semen and feel a strong sense of shame, drawing the attention of the people.

    But unlike Si-woo’s wishes, Su-ah places the entire bag on the card reader sensor without any signs of panic.

    Then, holding the bag with both hands, she starts to fumble around with the contents of the bag, moving them around.

    Soon, a “beep” sound is heard from the ticket gate sensor terminal.

    Su-ah passes through the ticket gate smoothly, as if nothing had happened.

    Si-woo is feeling momentarily empty and bitter.

    The sadistic impulse that surges up in reverse from the disappointment of not seeing Su-ah looking flustered and troubled.

    Si-woo waits for his turn, passes through the ticket gate, and approaches his younger sisters.

    “If you can use the card like that, you can just carry the bag around without cleaning it~! You can go around like that all day and tell Seon-ju to take care of it when you get home.”

    Si-woo approaches Su-ah and whispers in her ear in a small voice.

    Su-ah shrinks her body slightly upon hearing Si-woo’s low and small voice.

    “Since you need to wipe your smartphone and use it right away, buy one pack of wet wipes for now~! And buy one waterproof bandage, just in case!”

    Si-woo continues, as if designating the things to buy at the convenience store again.

    “Okay…”

    Su-ah nods her head diligently as she answers, twitching as if Si-woo’s whispering in her ear tickles her.

    “And when I think about it, I think you can just use the panty liner as is. It’s inside your underwear anyway, so it won’t be visible, and you won’t be able to tell where the smell is coming from when you’re among people, right?! How is it? Is it okay?”

    Si-woo is making an unreasonable request that goes beyond common sense to Su-ah, as if coaxing her.

    Si-woo was determined to make Su-ah feel the humiliating shame and isolation that she should have felt at the ticket gate just now, even through direct orders.
