    In the house where Se-young is preparing breakfast…

    Si-woo, completely naked and with a condom covering his penis, crossed the living room and went up to the second floor.

    Si-woo’s lewd exposure act to deliberately show Se-young in the kitchen

    The fact that this act was not stopped by any of the family members in the house seemed to fully satisfy Si-woo’s dominant excitement.

    Moreover, Si-woo’s act was not just simple exposure.

    He even showed Se-young the sight of grabbing his massively erect penis, which was wearing a condom, with one hand and shaking it up and down.

    These days, not only high school students in elementary academies but also younger students receive sex education quite early.

    The state of a man’s erection, masturbation, and what a condom means are all things that someone of Se-young’s age, a high school student at the academy, can fully understand.

    What thoughts are going through Se-young’s mind as she watches Si-woo heading to the second floor naked and erect?

    Se-young seemed to have grasped the hierarchical relationship of the newly formed family to some extent by observing the conversations and attitudes between Si-woo and the other family members.

    Perhaps she already knows about the sexual relationship that Si-woo has with her mother and older sister Se-hee.

    However, even so, there was one part about Se-young that greatly concerned Si-woo, unlike his older sister Se-hee or his mother.

    Apart from what Se-young understands intellectually, it was about whether or not she could fully accept the lewd acts and relationships that Si-woo was trying to engage in.

    Thoughts and emotions swirling and mixing impulsively…

    The more he alternated between fantasies and worries, the more the thrilling, pleasurable shivers associated with the taboo seemed to spread through Si-woo’s body.

    **

    Si-woo walks towards older sister Se-hee’s room.

    Si-woo, reaching older sister Se-hee’s door, pauses briefly and glances at the smartphone he is holding.

    Several text messages had arrived in the smartphone’s notification window.

    Messages that arrived from Aunt Seon-joo

    Si-woo unlocks his smartphone and brings up the group chat room with his mother, Aunt Seon-joo, and older sister Se-hee on the screen.

    The photo of his mother that Si-woo had taken in the dressing room a moment ago and uploaded to the group chat

    A humiliating photo of his mother holding Si-woo’s testicles in her mouth is uploaded.

    Below it, there was a reply from Aunt Seon-joo who had seen the photo.

    ‘Oh my~ Sister~ Are you doing that from the morning? Have you decided to completely follow our master now~? I’m so jealous~~~!’

    Aunt Seon-joo, seeing the photo Si-woo sent, says to her mother in an exaggerated and teasing way.

    ‘You have to be careful when sucking there because that’s where our master’s children are~! Got it~?’

    Aunt Seon-joo, looking at the photo of her mother with Si-woo’s testicles in her mouth, speaks to her mother as if she were a mother-in-law, interfering.

    ‘Well~ I guess they’re grandchildren and granddaughters to sister, so I don’t need to tell you to be careful~? ㅋㅋㅋㅋㅋ’

    Aunt Seon-joo sends a text as if to remind her mother of her incestuous relationship with Si-woo and induce shame.

    The numbers next to the photo of Si-woo’s mother and the text messages sent by Aunt Seon-joo had all disappeared.

    It seems that both mother and older sister Se-hee have checked the contents of the conversation.

    Si-woo closes the chat window and turns on the camera app.

    And he takes a picture of his erect penis with a condom on.

    -Click! Click! Click!

    Si-woo takes a picture so that it can be immediately confirmed that it is in front of older sister Se-hee’s room, with the floor of the second floor and older sister Se-hee’s closed door in the same frame.

    Si-woo sends the photo of his penis that he just took to older sister Se-hee via text message.

    As if she had been waiting for it, the number next to the photo Si-woo sent immediately disappears.

    Si-woo turns the doorknob of older sister Se-hee’s room, opens it, and enters the room.

    **

    Older sister Se-hee’s room is filled with a lewd and obscene scent.

    Si-woo enters older sister Se-hee’s room, closes the door, and examines the situation inside the room.

    Older sister Se-hee was lying on the bed, covered with the blanket up to her head, as if she were asleep.

    Even though she was clearly awake, older sister Se-hee was lying with the blanket over her head, just like when he had taken Se-young there last night.

    In just a few days, older sister Se-hee still seemed too embarrassed to look Si-woo in the face, as his position and status had changed from younger brother to master.

    Even after having such intense sex several times…

    Or was she secretly afraid after seeing the photo of him humiliating their mother from the morning?

    Older sister Se-hee, who would have been aroused all night while breastfeeding Se-young

    Si-woo approaches the lower part of the bed where older sister Se-hee is lying.

    Si-woo puts his hand on the bed near older sister Se-hee’s feet and climbs on top as if lying down.

    Si-woo grabs the bottom of the blanket that older sister Se-hee is covering herself with, with both hands and slowly lifts it up.

    Older sister Se-hee’s blanket is lifted up as if folded in half.

    From inside the blanket, older sister Se-hee’s smooth and seductive legs are gradually revealed.

    The blanket slowly folds up along older sister Se-hee’s firm thighs to her crotch.

    Each time older sister Se-hee’s slender and voluptuous lower body was gradually revealed outside the blanket by Si-woo’s touch, her legs twitched slightly and tightened inward.

    Si-woo puts the blanket he picked up down on older sister Se-hee’s pelvis.

    And he spreads older sister Se-hee’s legs apart, creating space.

    The thickly swollen mound and split valley between her legs spread out before Si-woo’s eyes.

    Clear and smooth spring water flowed from between older sister Se-hee’s split valley.

    Si-woo kneels down and positions himself between her spread legs.

    “I… went into older sister Se-jin’s room yesterday…”

    Si-woo speaks calmly, as if knowing that older sister Se-hee is awake.

    As if reacting to Si-woo’s voice, older sister Se-hee twitches her spread legs.

    “I also texted mom in the morning…”

    Si-woo tells older sister Se-hee in order the details that have been added to his smartphone yesterday and today, as if he is reporting to her.

    Then, Si-woo holds up the smartphone he was holding and opens the chat window with his mother.

    With the chat window with his mother open, Si-woo puts his smartphone inside the blanket that older sister Se-hee is covering herself with.

    Folded in half, inside the blanket that is only covering older sister Se-hee’s upper body, he gropingly finds her hand and puts his smartphone in it.

    Older sister Se-hee receives Si-woo’s smartphone and hesitates for a moment before creating space inside the blanket.

    Older sister Se-hee is checking her smartphone while covered in a blanket, just like last time.

    Older sister Se-hee would soon see the quarrel between Si-woo and her mother that morning, as well as the secret documents found in older sister Se-jin’s room’s desk drawer last night.

    Not only that, but also the contents of the conversation exchanged with Aunt Seon-joo…

    Si-woo watches silently, as if waiting for older sister Se-hee’s reaction.

    Perhaps realizing that Si-woo’s gaze is fixed between the mounds of her crotch, older sister Se-hee’s legs were trembling nervously.

    Then, older sister Se-hee’s vulva was closing and opening as if rippling.

    Older sister Se-hee seemed to be checking the conversation that had taken place between her mother and Si-woo.

    Si-woo reaches out and puts his hand on older sister Se-hee’s crotch mound.

    Si-woo separates older sister Se-hee’s heaving labia with his index finger as if drawing a line.

    Si-woo’s fingers caress older sister Se-hee’s wet labia that have been dug up.

    “Heut!”

    Older sister Se-hee lets out a groan, as if surprised by the stimulation of the finger touching her sensitive skin.

    With his finger inserted into older sister Se-hee’s pussy, Si-woo was enjoying the sensation of her smooth inner flesh that intermittently wrapped around his finger, as if savoring it.

    Older sister Se-hee’s sensitive wrinkles tightened, wrapping around his finger countless times.

    Older sister Se-hee must have been getting excited while looking at Si-woo’s smartphone.

    Si-woo pulls out his finger and brings his lips between her spread legs.

    Si-woo begins to stroke older sister Se-hee’s fleshy thighs as if caressing them with his lips.

    “Haa…”

    As strength enters older sister Se-hee’s body along with a gasp, her legs seem to stiffen and tighten inward.

    Si-woo pushes older sister Se-hee’s thighs out with both hands to prevent them from tightening inward.

    Then, between her legs, which are widely spread apart, he pushes his tongue into the gap between the split petals and strokes older sister Se-hee’s pussy along with his lips.

    “Haaht…heu-eum…haa-ahp”

    Older sister Se-hee’s body is vibrating according to Si-woo’s lip movements.

    While older sister Se-hee is checking the spoils she has stored on her smartphone, Si-woo is caressing the inner flesh and protrusions between older sister Se-hee’s valley.

    While barely enduring Si-woo’s cunnilingus, twisting her pelvis, older sister Se-hee did not seem to stop checking her smartphone.

    -As if desperately carrying out Si-woo’s order to check her smartphone…-

    “Chyuup! Suu-uup~! Suuup~!”

    The movements of Si-woo’s mouth and tongue licking her pussy become more violent and rough.

    -As if older sister Se-hee, who is enduring cunnilingus and checking her smartphone according to his orders, is hateful…-
