Inappropriate Thoughts
The flying fortress cut across the sky like a castle suspended in midair. It was Inarinax, the Tanalif Grand Duchy’s aerial stronghold. Inside the Grand Duke’s chambers, tucked within one of the countless towers crowning the fortress, Lua Tanalif paused while reading her documents. A flash of pink at the edge of her vision made her lift her head.
It was her older brother—now her older sister—Sia Tanalif. Floor-length pink hair, lush and voluminous, completely hid Sia’s back from view. Ornaments woven through the strands by a maid’s expert hands turned the whole cascade into something breathtaking, like a flowering tree in full bloom.
Lua’s lips curved into a soft smile. She approached her brother in silence.
“Brother. Does the view please you?”
The pink fluffball gave a visible shiver. Sia, who hadn’t noticed her approach, had been startled by the sudden voice. The sight was so unbearably adorable that Lua’s heart squeezed with painful sweetness.
“U-um, yes. This is the first time I’ve seen the Grand Duchy from this height, s-so…”
“…I see.”
Lua gazed at her brother with quiet pity. This was indeed Sia’s first time setting foot on Inarinax. Lua herself had ridden the flying fortress many times since childhood, often accompanying their father, the former Grand Duke, on expeditions as the designated heir.
If only her brother hadn’t been trapped inside the castle by that curse, he too would have stood here countless times.
Beyond the window, the Tanalif territories drifted past—endless white snowfields, savage mountain ranges, and the occasional lonely village. Long ago, the previous Grand Duke had stood in this very spot and said:
‘Every snowfield your eyes can see belongs to me, and one day it will belong to you. Every soul living upon this land is my responsibility, and it will become yours.’
But Father. Brother is also one of the people living on this land. How could you have been so cruel?
“Eep…”
Sia let out a strange little sound and flinched. Only then did Lua realize her own hand had been gently stroking that long pink hair. She snatched it back at once.
“Ah! Forgive me. I didn’t mean to—your hair simply looked so beautiful that I…”
“N-no, it’s all right. Actually…”
Sia turned around. Cheeks flushed, head shyly lowered, she placed her own small hand where Lua’s had been.
“I-if it’s not too much trouble… could you do it a little more? Ehehe.”
That innocent face made Lua want to shove her cock between those pretty lips and pull out after a single thrust—
“Of course. As much as you wish.”
Ignoring the monstrous thing writhing between her own legs, Lua resumed stroking her brother’s hair.
“Eep…”
“…Hah.”
Each pass of her fingers released a sweet fragrance that clouded Lua’s mind.
“U-um, if it’s bothersome…”
“…It is bothersome.”
Like an obedient bitch, Sia sank to her knees and lowered herself before her younger sister. When the older sibling lifted the hem of the Grand Duke’s skirt, the massive, filthy cock—thick with the heavy musk of a male—sprang free.
“Ah…♡”
Sia parted her lips with careful reverence. Lua swallowed hard at the sight of that small, glistening tongue. The moment her swollen glans pushed into that warm, wet mouth, the pleasure would be so intense it might melt her brain. Bracing herself for the coming ecstasy, Lua fought to keep her sanity intact.
“Mngh…♡”
“Haaang!♥”
The outpost town clinging to the Northwest Barrier came into view as Inarinax slowly descended. Human soldiers marched down the lowered stairs and formed ranks on the ground. Fairy knights soared through the air and landed neatly before them. At the head of the knights stood Lua, a Grand Fairy in her full majestic power.
Opposite them, the barrier garrison had already assembled to welcome the Grand Duke.
“Lua~ You’re late~ Why did you only come now~!”
A figure in lavish clothing dashed forward and threw herself into Lua’s arms. The woman was petite like Sia, with the same silver hair and crimson eyes.
“…!”
Lua stiffened at the unexpected physical reaction of her body, yet she could not show any sign of disturbance before so many eyes. With perfect composure, the Grand Duke grasped the woman and gently but firmly pried her away.
“You never change, Rina Tanalif. I distinctly remember telling you not to behave this way in public.”
“Aing~ Call me sister like you used to~!”
“Rina, sister. You mustn’t make Lua, sister any more uncomfortable.”
“Kyaa~ But I’m just so happy to see her~!”
Another woman stepped up from behind and pulled Rina back. She too had silver hair and crimson eyes, yet she towered over most men. Though her body was voluptuous and beautiful, the armor encasing that tall frame made her far more intimidating than any ordinary knight.
“Mina Tanalif. It has been a long time.”
“I have been waiting, Lua, sister. …Though the person beside you… could it be…?”
“Ah.”
All three pairs of Tanalif eyes turned at once. Clinging to the Grand Duke’s side was a woman trembling like a rain-soaked puppy.
“H-hello, Rina. Mina. It’s… um… been a really long time. Do you… remember me? Ehehe…”
Sia Tanalif scratched her head awkwardly and offered her cousins a timid greeting. Rina and Mina exchanged stunned glances, too shocked to answer at first.
“…Sia, brother?”
“Y-yes…”
Mina fought the urge to let her jaw drop. She had heard the rumors that the Grand Duke’s eldest son had become a woman, but seeing the reality in person was overwhelming. She met Lua often for family matters, yet she had not laid eyes on the reclusive Sia since the transformation. This was their first meeting since those carefree childhood days.
“B-brother… I’m not sure if it’s proper to say this, but you are truly… beautiful.”
“Eh? R-really? Ehehe… th-thank you!”
Sia squirmed in embarrassment at Mina’s flushed compliment. Mina was shocked by the gender change, yet she was also sincerely awed by Sia’s loveliness. Her own large, muscular frame had always left her insecure about her femininity; she secretly yearned for the delicate grace that women like Sia possessed.
—Who is that beauty?
—To think such a woman existed in our duchy…
—His Highness never seemed interested in men. Could that person be His Highness’s lover?
Murmurs began rippling through the barrier garrison. Sia noticed the attention and shrank even smaller. She remembered Angelica’s words that sometimes even on the battlefield one must pursue beauty. A single blossom appearing amid the stench of blood and sweat was raising the soldiers’ morale by its mere presence. Lua felt an odd surge of pride.
“Ahem. That’s correct, everyone. This is my older sibling, Sia. My very own brother.”
“Hah…!”
Lua gripped Sia’s shoulder and gently pushed her forward. Sia’s face burned scarlet, untouched by the frigid air of the snowfields. When Lua slyly slid an arm around those slender shoulders, Rina narrowed her eyes.
“Hmm— Sia, older brother, is it…”
Lua left with Rina, the officer responsible for the barrier, to discuss the reorganization of forces. In the meantime, Mina would show Sia around the outpost town.
“The soldiers’ families live here and support the garrison. Merchants have set up shops as well, so nearly anything can be found.”
“I-I see.”
“This is the forge. Most of the troops’ weapons are maintained here.”
Mina loved every corner of the outpost, but the forge was her favorite. Even in the heart of the snowfields the fires never died; the ringing of hammers against iron resonated deep inside her chest.
…Yet was this really a suitable place to bring a delicate noblewoman? Unlike herself, who lacked feminine grace, most women probably wouldn’t enjoy the heat and noise. Perhaps she should have started with a shop selling pretty dolls or jewelry?
Then again, brother had originally been a man, so maybe—
Burdened by anxious thoughts, Mina glanced back. As expected, Sia’s expression had grown visibly tense.
“Brother… are you uncomfortable here?”
“Ah, n-no, it’s just… after my body became female, places like this feel a little overwhelming. Hehe. Pathetic, right…?”
Sia smiled sadly, shoulders hunched. Cute cute cute cute. Mina’s heart melted at the sight of the small, timid creature before her.
“Brother… I have one request.”
“Hm? What is it?”
“C-could I hold your hand? Like we did when we were children.”
Mina knew how ridiculous the request sounded and couldn’t meet Sia’s eyes. Asking to hold hands with a cousin at her age was mortifying. Yet a soft, warm touch enveloped her fingers. Looking down, she saw Sia’s small hand gently but firmly wrapped around two of her large ones.
“Mina’s hands really are big, ehehe.”
“Aah…!”
The effortless kindness nearly brought tears to Mina’s eyes. Most beasts fled at the mere sight of her massive frame, yet this gentle creature had taken her hand without hesitation. It felt like successfully taming a small, precious animal.
“Oh my, Mina, so this is where you were?”
“Rina, sister?”
Rina approached with a bright smile, eyes curved like crescent moons.
“Weren’t you supposed to be with Lua, sister? The troop reorganization…”
“I left that to my husband and came here instead.”
“Sister… you really mustn’t push every duty onto your husband. You are the one officially in charge here.”
“Aah~ Save the lecture for later. Right now I want to talk with the cousin I haven’t seen in ages. Isn’t that right, Sia sister?”
“Eep…”
Rina’s smile carried a chill that made Sia shrink back instinctively, half-hiding behind Mina’s taller frame.
