The Physician's Observation
Though she was called the personal physician, Dimaria’s true profession was not that of a doctor. She was a mage who had been exiled from the academic world after delving too deeply into forbidden arts. The previous Grand Duke had taken her in when she had nowhere else to go. Of course, it was only to treat his daughter’s curse; he had shown her no true consideration. Even knowing that, a debt was a debt. Dimaria had resolved to do everything in her power for the Tanalif family.
Most of her daily work involved researching the curses that had accumulated in the bodies of the Grand Duke and her older brother. For that purpose, close observation of the symptoms was essential.
Creak. Squelch. Creak. Squish.
“Hngh… Oh, O-oppa… Ahh!”
“D-does it feel good…?”
“Yes, so much… hngh, it feels so good…♥”
The Grand Duke sat on the bed with her legs spread wide. When her skirt was fully lifted, a thick, rigid pillar of muscle rose proudly. Sia was caressing it devotedly with her delicate, fern-like hands. The Grand Duke’s cock and her brother’s hands were already drenched in slick fluid.
The Grand Duke had said she only felt sexual desire toward her older brother. And it seemed she could not relieve that desire with anyone else. If this was truly caused by the curse, then something should have happened while the two of them engaged in this simulated sexual act.
Dimaria tried to focus on the unclean energy the curse produced. But it was not easy.
…This is seriously fucking hot.
Silver hair carrying the chill of the north, and crimson eyes that gazed upon the blood of enemies. One of the most powerful fairies in the world was making an expression on the verge of melting. Even to another woman, the sight of a beautiful lady panting in pure lust was enough to make her groin itch unbearably.
Dimaria kept catching her hand as it drifted downward, twisting her thighs together, barely managing to maintain her concentration.
“I’m sorry, oppa… hngh♥ This is… wrong… haa♥…”
“W-what’s wrong about it? This isn’t wrong at all.”
“Really? Oppa, do you mean… you…?”
The Grand Duke’s face was filled with expectation for a certain answer.
“If your little sister is suffering, it’s only natural for her big brother to help. There’s nothing wrong with that. Ehehe.”
Her brother smiled innocently. It should have been the model answer, yet for some reason the Grand Duke didn’t seem to want that reply.
“I… I would never harbor such improper feelings toward you… that’s why I’m doing this…”
In this special situation, he meant the act itself wasn’t wrong. In other words, in normal circumstances, it would be wrong. The act of siblings performing simulated sex accompanied by mutual sexual desire.
The Grand Duke gave a somewhat lonely smile.
“That’s right. I… would never harbor such feelings toward you either… hngh♥”
The Grand Duke had no leisure to dwell on that inexplicable emptiness. Her brother’s hands were terribly clumsy, yet simply being touched by him made her cock feel like it was melting.
It’s so hot… like my hand might burn…
When she had performed oral sex on him in the corridor late at night, Sia had been too dazed to pay attention to many things. But now that she could afford to take her time, she felt everything at once. The massive rod brimming with the heat of life that would not cool even in the northern snowfields. The veins pulsing more powerfully than her own frail heart. And the scent that clouded her mind.
The thick, damp male scent pooled in his most secret place. The powerful predator’s musk that made a pathetic female submit.
“Haa…♡ Lua’s massive cock…♡ It’s incredible…♡”
“Huh…? Hngh…♥”
In her dazed state, Sia didn’t even realize what she had muttered.
Dimaria checked her watch. Thirty minutes had already passed, yet the Grand Duke had not ejaculated once.
“Your Highness. Is the stimulation perhaps insufficient?”
“Ah…?♥”
The melting Grand Duke finally seemed to remember a third party was watching and looked slightly embarrassed.
“I-it is a little lacking. Oppa’s hands are so small and soft…”
That was part of what made it good, but Sia’s hands were too small in surface area and too weak in strength to satisfy Lua’s enormous member.
“S-sorry. Then… should I use my mouth…?”
“No! You’ll hurt yourself again!”
“B-but… it’s almost time…”
Lua had come here before dawn, but even then it had already been time for the Grand Duke’s duties to begin. She could not afford to delay any longer. Of course, the duchy would not fall into great trouble if the Grand Duke did not handle matters personally. There were many excellent retainers. But it was Lua’s way and conviction to handle whatever she could with her own hands.
“Then…”
“Mmm?”
“C-can I… borrow your feet…?”
While pondering a solution, the image of Sia’s soles as she lay on the bed had floated into Lua’s mind. The way her pale, slender toes had wriggled. Surely her monstrous cock had gotten hard at the sight.
“F-feet? How…?”
“Like this…”
The Grand Duke instructed her brother into a specific position. Lying on his back on the floor, legs raised, knees bent into a diamond shape.
“U-ugh…”
Sia obediently assumed the pose as ordered, but he could not bring himself to open his eyes. First, because it was far too embarrassing. From Lua’s perspective, the secret sight beneath his skirt must have been completely exposed. Second, because it was physically exhausting. Sia’s frail body could not maintain the raised-leg position for long.
“Haa… haa… haaah…♥”
Lua’s eyes shimmered with dangerous hunger. She stared at Sia with the expression of a long-starved beast about to pounce on its prey.
God, I really need to fuck that.
Her toes, trembling as strength gradually left them. The feet were shaped so lewdly one could almost mistake them for a woman’s sex. The rounded parts were flushed a obscene pink like an aroused face. Delicate ankles, smoothly extended calves, irresistibly sweet pink knees. Soft, bouncy thighs and a pelvis that spread beautifully despite her small frame.
“A-ahhhhhh—♥”
With a bestial scream, Lua descended to the floor. She grabbed both of Sia’s feet and pressed them against her cock. Using the hollow of his soles to squeeze it tightly, she began thrusting her hips.
Squelch, slurp, squish, squelch.
“O-ohhh—♥”
It definitely had a different charm from hands. Although Sia’s feet were small and dainty, they covered a wider area than his hands, and since Lua was holding them herself, the pressure was much stronger.
“Heuht, heuuugh…♡”
With every thrust of Lua’s hips, Sia’s body shook back and forth. Yet strange sounds kept escaping his mouth against his will.
T-this is weird… it’s just feet…♡
His pretty feet were being utterly ruined by the sticky fluid. For some reason, that fact kept sending strange thrills through Sia. It felt like someone had thrown kindling into his brain and lower belly and set it ablaze, heating him from the inside. His crotch tingled, and deep inside his body a constant throb♡ throb♡ refused to stop.
“Ohoook♥”
The dignified Grand Duke had vanished, leaving only a vulgar beast making strange moans. Sia found it incredibly unfamiliar, yet he was overjoyed. The brother he had thought completely useless was making his little sister happy.
“O-oppa… I think… I’m going to… cum—!”
The oncoming climax choked Lua’s breath so badly she could barely speak. But if she came like this, her brother would be left in a miserable state. Not wanting to dirty Sia any further, Lua tried to pull away.
Sia clearly noticed his sister’s considerate heart. Yet for some reason, he wanted to reject that kindness.
“It’s okay… heuugh♡ It’s fine…♡”
Squeeze—
“Hoooh?!♥”
His toes curled inward, stimulating Lua’s cock. The startled Lua looked down at her brother’s face.
“Just cum…♡”
His brother’s face looked utterly unfamiliar. Eyes narrowed lewdly, a face filled with craving. Not the gentle brother he had always known, but rather—
Squeeze—
“Hngh?!♥ S-squeezed, ooooooh?!♥”
Spurt, spurt, spurt!
At the last moment of sanity, Lua released her grip on Sia’s feet the instant she began to ejaculate. If she clenched with full strength at the peak, she might snap his ankles.
Splurt!
“Eut♡”
The semen poured out like it was being scooped from a bucket, splattering across Sia’s face. He squeezed his eyes shut and accepted the continuous flood. It was as hot as molten lava. The terrible stench kept pouring into his nostrils, yet somehow his lower belly throbbed in response.
Squeeze— squeeze—
“Uooooh?!♥”
Spurt! Splurt!
The sensation felt too good. Wanting to know what it was, Sia gently stroked the side of Lua’s massive shaft with the hollow between his toes and soles. Matching that gentle movement, Lua wore an utterly stupid, vulgar expression as she milked out every last drop of semen left in her urethra.
“Haa… haa… haa…!”
After finishing her refreshing morning ejaculation, intelligence gradually returned to Lua’s face. The first judgment she made was that she was too embarrassed to stay here any longer. She confirmed that her shrunken member was properly concealed.
“I-I should go now…”
As she tried to stand, Lua witnessed the terrible scene she had created. Her brother’s face and his beautiful pink hair were completely matted with the cloudy white fluid she had sprayed, turning him into an incredibly arousing—no, a hideous sight.
“O-oppa, I’m sor—”
“L-Lua, haa— you’re late. Go quickly. Haa—”
Sia, panting with obscene breaths, was so covered in semen that his expression was barely visible. Lua accepted her brother’s consideration, nodded, and rose from her spot.
“If you discover anything, organize it first. I will review it after finishing my duties.”
“Ah, yes.”
This was merely a necessary act for medical examination. Lua gave the order to Dimaria as if nothing had happened. Yet she could not even meet her eyes out of shame and fled the room as if escaping.
Thanks to that, the personal physician was not caught rubbing between her legs with her fingers instead of conducting any proper examination.
Still, it was not without gain.
“Um, Lord Sia. In my professional opinion… Lord Sia?”
“Heek— heek— heek—♡”
A large pink fluffball was making sounds like a bitch in heat. It was not difficult to tell that the fluffball wrapped in its own hair was Sia.
“Lord Sia?”
“D-Dimaria… I also… heuuugh—♡”
With heart symbols floating in his eyes, Sia had both hands shoved between his own legs.
“My body keeps feeling… hngh♡ strange… I want to feel good like Lua… but I don’t know how—♡”
