Sia's Night
Sia turned her eyes away from the massive, monstrous cock radiating overwhelming virility above her own sex, desperately trying to focus on Lua’s words. No matter how she turned them over, they refused to make sense.
“Lu-Lua… are you telling me to get pregnant, or not to…?”
Sia was terrified by how unhinged her little sister had become, yet she forced a smile as she asked. The only reply was the Grand Duke’s icy, expressionless face.
Slap!
A stinging smack across the cheek.
“Brother, do not utter the word again.”
“S-sorry… I was wrong. Please don’t hit me. I won’t say it again.”
Stroking her burning cheek and wiping away the nosebleed, Sia apologized through tear-streaked eyes. In all her life, the only person who had ever struck her was Lua. Her father had ignored his son completely, and she had never had a tutor who would resort to physical discipline. The very act of being hit was therefore unbearable.
“If you become pregnant with my child, brother, then there will be no need for you to be impregnated by another man.”
“Y-you… me? You’re going to…?”
“Yes. I will impregnate you, brother.”
Sia asked again, doubting her own ears, but Lua simply nodded as though she had stated the most obvious fact in the world. The moment she heard the answer, a terror so intense Sia thought her heart might explode flooded through her.
Until now, soothing Lua’s lust had been an act that crushed her pride as a man. But it had only been a matter of that flimsy pride. As a member of the Grand Ducal house, she could sacrifice that much for the Grand Duke’s sake. What Lua proposed now, however, had nothing to do with duty.
Sia carrying Lua’s child. Incest. While not unheard of, no one would ever call it honorable. It would remain an indelible stain on Grand Duke Lua Tanalif’s name. Any child born of such a union could never ascend the ducal throne with glory.
Sia’s head shook on its own, trembling.
“N-no. Absolutely not. A child should be born between people who love each other.”
“We love each other, don’t we?”
“Th-that’s as siblings, not… not as lovers.”
“……Siblings.”
A trace of calm seemed to return to Lua’s eyes. A fragile hope bloomed in Sia’s chest that her sister might regain her senses with just a little more time.
“……But I don’t want to send you to another man, brother. I know exactly how painful a life that would be for you.”
Lua lowered her head and muttered. For other women, taking a husband and bearing children might be ordinary. But for Sia, who had always seen herself as a man, it would be the complete annihilation of her male identity. It was nothing less than the erasure of an entire person. The younger sister’s tender concern for that very fact reached her older brother clearly.
“I……”
You don’t need to worry. This brother can sacrifice far more for the Grand Ducal house. Even if I must become someone’s wife, even if I must become the mother of the next Grand Duke.
She wanted to say it, but Sia forced herself to think calmly once more. She remembered the mad light in Lua’s eyes when the Grand Duke had screamed that not even the Emperor could take her brother away. Saying she would gladly accept another man might only provoke her sister again.
“Besides… we don’t even know if it’s possible.”
“……What isn’t?”
“Even though I’ve become a woman, I don’t know if this body can actually carry a child. Because of the curse, it may not be a normal female body at all.”
Sia squeezed her eyes shut, bracing for the slap that might come at any moment.
“……That’s true.”
Lua answered with a slightly dazed look. Fortunately, as long as the word wasn’t spoken directly, she didn’t seem irritated.
“L-let’s have the physician check, then. It might be impossible anyway, so there’s no need to worry about it yet.”
“……You’re right. You’ve always been wise, brother. I knew that. There simply hadn’t been a chance to prove it until now.”
“E-ehehehe……”
Praised by the family head, Sia broke into a foolish, delighted grin. In her joy she completely missed the way Lua’s eyes curved into a sly, predatory shape.
“Then let’s confirm it immediately.”
“Huh? Then we should call the phys—kyaaah!”
Lua seized both of Sia’s slender ankles, lifted them high, and spread them wide apart. The view was breathtaking—lower belly, groin, buttocks, thighs, knees, and the soft hollows behind them all laid bare at once. Mostly pure white, yet flushed with a sweet pink in all the most sensitive places, it looked unbearably appetizing. And of course, the final touch that perfected this living masterpiece: her older brother’s shyly closed pussy, lips like a flower on the verge of blooming.
“Lu-Lua? Weren’t we going to the physician?”
“Why bother with a physician? We can check right now♥”
“Wh-what?”
“I’ll simply try to impregnate you right now♥ Then we’ll know whether it’s possible or not.”
“N-no, no, don’t—stop it!”
“When you make such a despairing face, brother, it only makes me want to do it more!”
“Hyaang?!♡”
Lua thrust her hips forward, driving the fat glans inside. Sia’s secret place was assaulted and a moan tore from her throat. But the exact situation Lua desperately craved—the one Sia absolutely did not want—did not occur.
“……Huh?”
Lua tilted her head. The Grand Duke’s enormous cock had not entered Sia’s pussy; it had only slid over the surface.
“Haa…… haa……!”
Sia panted as though an arrow had just whistled past her ear.
“Th-this…!”
“Hng?!♡ Huat?!♡”
Again and again Lua tried to shove her cock into her brother’s cunt. Each time the glans merely glided across the slick labia; the thick shaft never managed to breach the entrance.
There were several reasons. The most basic was that Lua’s penis was grotesquely large while Sia’s passage was painfully tight. The Grand Duke’s member far exceeded any ordinary man’s size, yet Sia’s small frame meant an equally narrow opening. Moreover, although Lua possessed an absurd cock, she had lived her entire life as a woman. Her technique at wielding it was still that of a complete novice. Aiming a male spear accurately into a female’s hole was far more difficult than it appeared.
“Why! Why won’t it go in?!”
“Aang?!♡ Ungh?!♡”
Lua felt no pleasure at all from the repeated failures. Sia, however, felt like she was losing her mind. Thanks to Lua’s raw physical strength, the burning-hot cock kept perfectly flicking her swollen clit with every thrust. Pleasure washed over her—enough to feel, but never enough to crest. That maddening, perfect torment continued without pause.
“I see. I simply need to aim better.”
True to her reputation for mastering anything she set her mind to, the Grand Duke quickly adapted. Lua gripped the thick shaft with one hand and carefully lined it up between the delicate folds. With the other she pinned her brother’s groin, minimizing any movement of the target.
“Hiiik……!”
An ominous certainty crawled over Sia’s skin, raising gooseflesh across her entire body. This next attempt would surely succeed. The Grand Duke’s monstrous cock would pierce straight through her brother’s inner walls without mercy.
“N-no…!”
It would only leave wounds on both of them. Once Lua regained her senses she would surely regret it—the knowledge that she had tarnished her own honor. At the same time, Sia realized something in the face of crisis. She had believed she could do anything for her little sister, but she was not yet ready. To have her virginity stolen here would mean fully accepting herself as female. She did not want to lose the last shred of pride that still let her call herself male.
“Hiiiik……!”
Because Lua was using both hands, she had released Sia’s legs. Sia immediately flipped over and began crawling away on all fours. But the “tail” she left behind was far too long.
“Where do you think you’re going?!”
“Kyaaaaak!”
The furious Grand Duke seized her brother’s long pink hair and yanked her to a halt. The scalding pain in her scalp made Sia’s eyes water as she froze.
“How dare you! How dare you try to run from me?!”
“P-please stop! I’m not ready yet!”
Even if Sia had sprinted with all her strength, Lua could have caught her hopping on one foot. Knowing that, Lua still felt a frantic impatience. Her cock felt ready to burst, and the constant failure to penetrate had left her desperate. Afraid of losing the chance, she tightened her grip on the pink hair even more.
“You lewd pink-haired bitch!”
“Ack! Lua! I’m begging you, stop!”
While Sia thrashed, Lua brushed aside the long pink locks that had completely hidden her brother’s backside. When the pale, plump buttocks were finally revealed, she grabbed them roughly.
“Hng!?♡”
“Stay still!”
The sudden stimulation made Sia’s body go rigid. Lua seized her pelvis, lifted it high, and before her brother could flee again, thrust her cock straight toward the waiting pussy.
Squelch!
“Haaang?!♡”
“Ah……♥”
Both of them shuddered violently, mouths hanging open, drool spilling as though lightning had struck them.
C-crazy……♥ Is this… a pussy? My cock is melting……♥
It wasn’t even halfway inside, yet the pleasure was already incomparable to anything they had done before. The inside of Sia’s body, heated perfectly by her brother’s temperature, squeezed the invading cock from every direction. While Lua savored the sensation with an expression drenched in raw lust, Sia slowly turned her head to confirm what was happening.
“Lu-Lua, that place… isn’t my… v-vagina—”
Squelch!
“Haang—!♡”
“Ahk♥ You fucking bitch! It feels too good! Aang♥”
Sia tried to tell the truth, but Lua gave her no chance to speak.
