My Little Sister Begged Me to Lick Her Feet
“Release that, Lucia. Before my patience runs out.”
“I—I’m serious! Please, listen to me! Big sister...!”
After my little sister had revealed the secret she’d hidden, I’d made a sincere effort to understand her. But this request crossed every line I could accept.
To make me lick her foot? With her own younger sister? No. Absolutely not.
“...If I don’t pull this off perfectly, Big Sister or I might not survive the day!”
“What...?”
I had turned toward the main residence, hoping the walk would cool my head. Yet the words that poured out of her made me stop dead.
“Speak plainly, Lucia. Who’s supposed to die?”
“Hic... It’s... me... or Big Sister...”
“Are you serious?”
“...Yes.”
‘...Hm.’
I probed her true feelings, but she showed no sign of lying.
Someone with no experience in high society at all couldn’t possibly fool my eyes.
Thank goodness. She wasn’t pretending she simply wanted to lick my feet.
“Explain yourself clearly. Why do you think you must lick my foot?”
“Th-the context is the same as last time...”
“Same? It wasn’t supposed to end there.”
“Yes... the original big sister kept tormenting me until I left home. She was the ultimate villain!”
...Sigh.
One misstep and I might be trapped in months of torment.
The only path left was persuasion.
“Lucia, what meaning could tormenting you here hold? No one else is around. The garden had maids, but here it’s only you and me.”
“Demonstrating the event is what matters! Last time Big Sister stepped on me and the real event triggered anyway!”
“...What event?”
Her shoulders twitched. Her eyes darted everywhere.
She was desperately hunting for excuses. Questioning her now would yield nothing.
“Please believe me... Big Sister...! If I don’t lick your foot, I’ll be sent to the Bad Ending tomorrow... I’ll die of illness... I’ll become a ghost and appear in your dreams...!”
In the end, she abandoned even excuses and clung desperately to my foot.
What a fool, my sister.
If I had spoken, perhaps Big Sister would have understood. But instead...
“Last warning.”
“Eh? Big Sister!”
If you weren’t my blood sister, I would have judged you a fool and walked away on the spot.
Be grateful you were born my little sister, Lucia.
“...Sigh.”
I gathered the hem of my skirt to my calf and slipped off my shoes, placing them neatly on the floor.
She wouldn’t have stinky feet, would she...? The day had been rather warm; my own feet had perspired. Ugh.
“Quickly... lick.”
“Yes! As politely and gently as possible...”
The soft, warm touch of her lips brushed the top of my foot and withdrew.
She was really doing it. My real little sister was licking my foot.
I squeezed my eyes shut against the shock, but for a long time nothing happened.
...Is this it? She only lifts and presses? What?!
I’d been careless... I hadn’t expected her to start so suddenly...
Something long and silky glided across the top of my foot.
I couldn’t see it—my eyes remained shut—but I knew it was her tongue.
Lick. Suck.
‘Ah... ah...’
The tongue that had slowly licked the top of my foot gradually moved downward, carefully licking each toe one by one... no, sucking them.
The sensation of my toes moving inside her mouth was far more delicious than I expected.
I kept my mouth tightly shut, biting back the moan rising in my throat.
“Good scent.”
Enough. Enough.
“No particular taste... but your skin is so flawless that licking it feels wonderful.”
Don’t comment on it, Lucia.
Use the moment I’m too stunned to resist to do whatever you like.
“I could keep sucking for hours...”
The sticky, slick movements of her tongue were something I had no idea she could do.
Something I might have read in a sensual novel as a teenager when I sneaked away to hide.
Doing something like this with my own sister.
What kind of thoughts led the original Lucia in the story to demand this?
To humiliate me? Being licked felt more humiliating... I couldn’t understand.
“How much longer... can you keep licking?”
“Just a little more. It’s almost done...”
What was almost done?
Normally I would have used logical reasoning to reach the answer, but my mind was melted into mush. I simply accepted her actions obediently.
Suction.
Minutes, perhaps hours, had passed.
The sister who had been stubbornly sucking my toes finally released me.
In my body it felt like an eternity, yet the sun outside the window suggested far less time had truly passed.
“Big Sister Lilith. Is... everything all right?”
“U-um...?”
“Something wet on your lips...”
“...Must have dozed off for a moment. That was an utterly meaningless time.”
I knew her excuse was flimsy, but I had nothing to say.
Your tongue felt so good I drooled.
If I had spoken honestly, I wouldn’t have been able to live with myself.
“Really? Oh, let me wipe it for you!”
She knelt gracefully and used a luxurious handkerchief embroidered with her own hand to clean my foot.
...The pattern on that handkerchief looks exactly like Father’s crest.
It seemed quite old. It might have been the one given to me when I brought her here.
“Big Sister. I am truly grateful for this. It was an experience I desperately wanted to test.”
“Test...?”
“Yes. To confirm whether repeating the original event—implementing it almost identically—would trigger the same outcome. Stepping on me last time was just daily life; it never reached the event stage.”
Daily life...
I see. So the version of me in the game was the worst kind of character.
Would I have turned out like that if I had been raised according to Mother’s wishes...? Just imagining it is terrifying.
“It’s clean now, Big Sister. Hehe.”
“Yes. Clean in every way.”
Only after carefully slipping my shoes back on could I rise.
My sister had caught me when my legs gave out, but... sigh.
“Big Sister Lilith. When will you visit again?”
She seemed to sense I was about to leave. She naturally escorted me toward the exit.
Ten years old and already quite clever, Lucia.
“Well... if I came too often, Mother wouldn’t be pleased. At least three days must pass.”
“Three days...”
“No, it might take longer. Michaela is coming soon.”
Michaela.
The moment her name left my lips, my sister’s body jolted.
She couldn’t help but be startled. The Michaela coming to visit now... was the Crown Prince’s double, not the real prince himself.
“Bu-but... do I really have to meet him...? Since it’s not even the real person...”
“Lucia. Nobles must always maintain dignity. A wise younger sister would understand Big Sister’s words, wouldn’t she?”
“...Yes, Big Sister.”
If the Crown Prince never visited periodically, other nobles would assume the Sadonium Duchy and the imperial palace were in constant rivalry.
That meant everyone here was performing a play that was never actually a play.
“I think that’s enough for the welcome.”
“Yes. When you come again, I’ll show you some surprises.”
“...I will never accept a request like this again.”
“Hehe, don’t worry. Even if it’s a big event, it’s nothing special.”
I wanted to hear what “nothing special” meant, but she wouldn’t tell me.
...I could feel no displeasure even though someone was obviously hiding something from me.
Was she doing it for me? Surely.
“Well then, until next time.”
“Yes. Until next time... beloved Big Sister.”

“Miss Lilith!”
“What is it, Yuna? Is Mother having another tantrum...”
“Prince Michaela has arrived!”
Three days had passed since I met Lucia.
As my mother’s fury began to subside and I considered going to see the girl, an unwelcome report reached me.
“...Now?”
“Yes. She is waiting at the entrance.”
“I see. I’ll come down immediately.”
She came without any appointment.
We had been interacting for quite some time, yet her impulsive behavior still felt unfamiliar.
‘...She arrived without an escort.’
I had stopped what I was doing and descended the stairs. I found the golden-haired noblewoman waiting with a calm smile.
Michaela Nois.
Crown Prince of the Empire and my fiancé.
A legendary genius already shining in every field.
“Hello, Lilith. Your attire is even more beautiful today.”
“Follow me to my room at once, Michaela.”
“So eager? I don’t mind.”
“Enough nonsense.”
I took her by the wrist and led her straight to the room.
Fortunate timing. I had several questions I wanted to ask.
Click.
As always, I dismissed Yuna and locked the door behind us.
Now the room contained only the two of us.
“Even as fiancée, you bring me here too abruptly?”
“...You may stop the act.”
No, not just the act.
“Really? Well, if it’s only the two of us...”
Michaela Nois. Twin sister of the Crown Prince.
Rumored to have been sold far away like a foreign bride, she was acting as the double for the unconscious Crown Prince.
“This wig is rather uncomfortable. It’s hot and stuffy.”
A strange connection had always bound us.
As children, when we first met at a social gathering, I never imagined we would end up like this.
“Michaela, has anyone ever discovered your double identity? Speak honestly.”
“Impossible.”
She removed the wig and untied the tight bandages concealing her chest, revealing a figure completely different from moments ago.
A perfect princess straight from a fairy tale.
That was why every nobleman had sighed in envy at the thought of her marriage.
“Even if someone had found out, it would have been fine. She would have disappeared before opening her mouth.”
“...Yes. That would have been you.”
But knowing her inner self, all I saw was a golden demon.
An existence who sacrificed herself to protect the empire... fittingly cruel for a royal.
Meeting her had never been easy.
Especially when she forced her beliefs on me, even as my fiancé.
I was too busy protecting my disguise to waste time saving the empire.
“So, why the sudden questions? As if you’ve already figured something out.”
...This would be another difficult time.
