After her brother had left, Ste continued to pace inside the room.


    "Ste, would you like to go to my brother''s room?"


    "…"


    What would have happened if she had epted the proposal just then? Dizzying fantasies clouded the mind of the academy''s blonde tsundere sister. She was aware that, after the exchange, her brother had grown closer to first-year juniors like himself.


    Everyone was vying for her irresistibly handsome and charming brother, even though he was considered a D-ss subject, the lowest rank, and less than untouchable in the academy society. Those who had met Kim Sang-hyuk in person knew well that such an evaluation was not fitting. Ste now understands this as well.


    "Brother."


    Ste, who now knew how to take responsibility for her brother''s erect cock, wanted to take things a step further. However, at the same time, it also meant lifting the only remaining taboo in their household: engaging in sex with her younger sister.


    Ste''s love for her brother Sang-hyuk had grown to the point where she no longer had any intention of hiding it, but she knew there were lines that shouldn''t be crossed. When a sister begins to tightly wrap her brother''s throbbing cock within her silken folds, there''s no turning back. In Korean expression, it would be called the "Gaejokbo bean powder family."


    The acts they had engaged in thus far could be excused as innocent transgressions. Two sisters were so devoted to their brother that their passion erupted in unforeseen ways. However, there would be no justification for the act of full-blown intercourse.


    And what if she were to be pregnant with her brother''s child?


    "Ah!"


    Ste let out an involuntary scream, startling herself. She mped a hand over her mouth.


    ''What kind of thoughts am I entertaining?''


    A child with her brother? Pregnant with Sang-hyuk''s baby? How could she, an aplished A-list mage at the academy, even allow herself to imagine such things?


    ''No, no!''


    Yes, she loved her brother, but it was as a sister that she loved him. She certainly didn''t want to bear his child. Despite these internal objections, Ste found herself lost in her fantasies.


    Delusion Sang-hyuk ON. Her imagined Sang-hyuk forcefully pushed Ste against the wall and whispered...


    "Ste, I love you."


    "Oh, how much?"


    "I want to fill you up without a condom."


    "~~~~~ Eh."


    ''If he says he wants to fill me up... Could I refuse?''


    A taboo among taboos. Impregnating his younger sister.


    Ste''s fantasies were spiraling out of control like an eight-ton truck with a broken steering wheel.


    The fact that her brother was going out on a date and leaving her alone at home added fuel to her wild imagination.


    She sneaks into her brother''s room.


    Peeking.


    "Well, I don''t intend to rummage through anything."


    Ste felt a slight sense of self-loathing for engaging in the perverted behavior she despised.


    She found her brother''s bed, her goal.


    The nkets were strewn about haphazardly.


    Just by discovering traces of Kim Sang-hyuk lying down and resting for a moment, Ste''s heart raced as if it would burst from her chest.


    Thump, thump, thump.


    The slightly disheveled nket and the sheets carrying her brother''s scent,


    It felt like a cradle made just for her.


    "Sigh…! Sigh! Hng, haa, hah… Hng…"


    Ste crawled right into the covers.


    Ste writhes with excitement, consumed by thoughts of sleeping with her brother today. Surrounded by his masculine scent, she naturally finds herself masturbating. Passively caressing her clitoral area, she reminisces about the warmth of her brother, who had held her so tenderly just moments ago.


    "D-grade subject…"


    Ste gasps, her eyes zing over as she inhales her brother''s lingering aroma. Her fingers never cease their fric dance, the subtle sounds of her arousal filling the air.


    "A D-ss brother... with an A-ss sister... Ah… Ah… How much… to be loved by... You have no idea what a blessing it is."


    After her bravadoden pretense fades away, her true emotionse pouring forth.


    "I love you... I love you. Brother, I love you. I love you more than Serena does.


    Desperate to take his cock in her mouth, Ste spares her damp, yearning pussy for the possible return of her brother''s member. She gently strokes her clitoral area, seeking relief for her overwhelming desires.


    Even though she initially resisted...


    The more she considers the "social taboo," the more licentious fantasies invade her mind.


    "Inside… ah… Are you going to fill your little sister''s pussy? Big brother…? Are you going to swell my belly with your seed?"


    Ste, feeling dizzy from the words she had just spoken,


    exhaled her breath and murmured.


    "It''s all because of you, big brother... You''ve given me these strange sexual fantasies.


    Even though it''s a fantasy, there''s a high likelihood of it bing a reality.


    After all, Ste is his stepsister.


    The fact that they don''t share a single drop of blood couldn''t be moreforting.


    Considering her brother''s physique, Ste can easily imagine the incredible and intense sex she would experience.


    His cock is so big, and he''s so handsome. A woman''s brain is already more than halfway melted from arousal before actually having sex, making it easier to ept her cock.


    "Oh, having sex with my brother… ? Ah, I shouldn''t do that. I absolutely can''t do that."


    Ste stimted her pussy, not caring that her freshly changed pants were getting wet.


    squish… squish squish squish…


    "Heh… Mmm… If my brother... wants to... release himself inside me... I can''t help it? Because I''m his little sister... Ah… Ah…"


    Masturbation intensifies.


    Ste, with her eyespletely unfocused, thrusts her hips up on her brother''s bed.


    "Mm… Yeah… Since I''m your little sister, will you..."


    In reality, she''s too shy to say this out loud.


    Desiring to have sex with her brother isn''t something a little sister should say.


    Yet, in a world of unspoken fantasies, it''s possible. Ste imagines the impressive cock she took in her mouth.


    She rubs her vagina crudely while envisioning him ejacting inside her.


    On her brother''s bed, surrounded by his scent...


    Ste reaches an intensely pleasurable climax.


    "Ah… Ah… Hot…!!"


    Pchut, pchut…?


    Nheless, there''s a lingering sense of dissatisfaction.


    Even the act of rubbing herself feels wholly insufficientpared to when her brother did it for her.


    No matter how much she thrusts her hips and murmurs vulgar sounds, it doesn''tpare to the pleasure she feels when her brother touches her with his hands.


    The unfulfilled longing ignites a fire within Ste''s heart. With her precious, one-of-a-kind virginity meant to be saved for her future husband, the thought of tending to her brother''s cock was simply unthinkable.


    Such a shameless thought; she shouldn''t entertain it.


    ''Serena…''


    Ste thought of her brother''s other half-sister, sharing the same blood as her, Serena. The thought suddenly crossed her mind that, on a weekly basis, Serena was the strongest rival in the house.


    "Phew…"


    Catching her breath, she pondered.


    ''Could it be that she''s been secretly progressing further with him behind my back?''


    When she first pleasured her brother with her hand on the infirmary bed, Ste couldn''t deny feeling a hint of betrayal upon learning that Serena had already been taking care of his sexual needs. In the midst of calming her heated desire, Ste''s body jolted upright as she realized something.


    ''Hold on.''


    Could it be that, once again, Serena was secretly orchestrating a buildup to delightfully stroke her brother''s dick with her sister''s vagina without anyone knowing?


    ''It''s peculiar that she suddenly went out to buy lingerie. She already has plenty of it.''


    Just how risqué must these undergarments be?


    Ste knows all too well that Serena is the kind of woman that men can''t help but adore.


    She may feign innocence, but she''s quite the temptress with her man!


    In other words, a refined seductress!


    "Brother… Have you ever put it inside me?"


    This isn''t a mere fantasy. It''s what Serena herself said during their first sisterly meeting.


    "I felt so full... reaching the innermost, deepest part... your hard cock... As if to say, ''Serena''s pussy is mine?'', it touched even my womb, and it felt so good."


    …


    "Regardless of how perverse our brother may be, he wouldn''t cross that line with his sister."


    That''s what Ste had said.


    "So we must be the ones to sway him."


    Why had they thought Serena would back down after hearing her brother''s warning—no coins?


    Even as his younger sister, Serena should have realized that day that she was more devoted to tending to her brother''s desires than anyone else.


    "I believe that a woman''s most precious gift to a man is herself."


    "Because your cock is the ce that can make me feel the happiest."


    ''Your cock, the ce that can make me feel the best...''


    Serena says her sister''s pussy can please a dick as delightfully as her love for her brother.


    Then Ste also had her chance.


    After all, Ste is one of the only two sister pussies in the world.


    ''Future husband? Pfft, there''s no such thing.''


    For an unknown future husband whose face, name, or birth are all mysteries,


    Holding back your feelings for the man you love right now will only lead to regret.


    All I need is my brother by my side.


    At an unconscious level, Ste had already relied on her feminine instincts.


    Assessing all of Kim Sang-hyuk''s abilities and drawing her conclusions as ifying them on a cutting board.


    Embarrassment and social taboos held her back, so every time her feelings tried to surface, she was startled and hit the brakes.


    In truth, her heart''s desire was...


    ''Brother… I wish you could be the father of our child.


    Handsome, big cock, capable?


    A highly desirable SS-ss male who earns a good living and would be able to protect me and our child once I give birth?


    The fact that he is my own brother.


    The unwavering number one male I wish to be the father of my child?


    ''Ahh.''


    Serena had already known.


    She wished she had been more honest sooner.


    Clutching the nket tightly, she let out a regretful sigh.


    ''What have I done?''


    It was Ste, writhing on the bed, unable to be honest due to her innate tsundere nature.


    Looking back, she had lovingly sucked his cock, and her brother had been fond of her as well.


    Yet she had rejected him at the crucial moment.


    Towards the end, she felt her brother''s tenderness as he tried to revert to a sibling-like atmosphere, which only made her regret grow deeper.


    It was at that moment.


    "Ste?"


    Serena opened the door and entered as if she knew Ste was in her brother''s room.


    Their eyes met.


    "Serena…"


    "You were on my brother''s bed."


    A strangely tense atmosphere engulfed them, as if they were engaged in a subtle battle of wits.


    Ste rose from the bed as if nothing had transpired and approached Serena.


    "Did you get the underwear?"


    "Yes."


    Serena smiled bashfully.


    ''That''s a smile that captivates men.''


    What man could resist such a lovely face? Now that I think about it, I truly wonder how her brother managed not to cross the line and resist it.


    "I even met my brother on the way here... He asked me to wear sexy underwear."


    "…"


    Ste snorted nonchntly.


    "Really? With the golden tip Serena taught me, I not only sucked my brother''s cock but also received his cum in my mouth."


    "…Really? Good for you."


    "There was so much cum... Phew… I feel like I can still smell the semen."


    "I don''t think it''s that strong. I can only smell Ste''s strawberry-scented toothpaste."


    "…"


    "…"


    The tension in the air hinted at the possibility of a sisterly feud over their brother. Thest time these two close friends had a disagreement was nine years ago.


    There hadn''t been any conflict since Ste silently devoured Serena''s dessert snack, Byo○, which she had stored in the refrigerator.


    It was entirely Ste''s fault.


    However, due to Serena''s gentle nature, which allowed her to yield in most situations, it was extremely rare for the two topete for something.


    "Where is your brother now, Ste?"


    "He went out on a date. Just so you know, we almost did it."


    "I see…"


    Serena''s lips curled up slightly.


    Ste felt uneasy because of that smile, which somehow seemed provocative, making her heart flutter.


    "If it were me, I would have held onto him so he couldn''t leave."


    "We finally had some alone time at home, and you didn''t have sex? If it were me, I would be getting my brother''s cock right now."


    … Ste hadn''t said anything of the sort, but that''s what it sounded like to her.


    "What''s the rush? My brother likes me anyway."


    "Ste, weren''t you scared of doing it with your brother?"


    "I''ve changed my mind. I''m just like Serena now."


    A deration of war.


    Ste looked directly at Serena.


    I''m uncertain if I can surpass these wicked breasts. Could it be Henna, or is she on the same level as that person?


    Ste seems slightly intimidated, but I believe the size of her chest does not determine the oue.


    A match… Is that what this is?


    Stees to the realization that she regards Serena as a rival.


    That''s why sparks, which were absent before, are now flying.


    Just as sounds are made when hands p together, Ste, who hasn''t been considered apetitor in the intimate affairs department until now, makes her move.


    As a result, Serena instinctively throws a countermeasure.


    The sisters confirm their feelings towards each other''s brother.


    And then…


    Swoosh.


    Ste murmurs as she brushes past Serena.


    "The one to get pregnant first wins."


    "…"


    Kim Sang-hyuk, who left to visit Yuuna, had no idea that such an event was unfolding at home.
