Acting Lord of the Vallancien Fiefdom.
And the eldest daughter of the former Baron Vallancien, and the sister of the next baron.
Yuri de Vallancien.
"...What the hell, seriously..."
Holding a single book in her hand, she was completely absorbed in the text.
A book where her younger brother revealed his previously undisclosed name—his pen name—in his latest work.
And a book that garnered everyone's attention with a format as unconventional as his last one.
『A Night Like Juliet's Magic』
"...Are you insane?"
Ever since she secretly read the manuscript in Adrian's room, she simply couldn't look away.
She would have loved to steal it, but that would just be advertising that she had been in and out of Adrian's room, so it was impossible.
Especially for Yuri, who valued face above all else due to her status, which lagged behind the central nobles, such a thing was unthinkable.
That's why she had waited so eagerly for Adrian's book to be released and finally obtained it.
"...Hitting the lower abdomen?"
It's hard to imagine.
Isn't a woman's lower abdomen traditionally where the womb is?
Even when she briefly learned martial arts in the past, she knew it was one of a woman's vital points.
Even if it wasn't as instantly panic-inducing as a blow to a man's groin, it could still cause significant aftereffects.
Adrian, who graduated top of his class from the Academy, must know that fact all too well.
Because he described hitting the lower abdomen as if it were some major turning point.
...If it weren't for the fact that the description leaned in a strange direction, Yuri would probably have found it easy to accept.
「...Unable to bear the trembling sensation of the throbbing ache in her lower abdomen.
Juliet, forcing herself to suppress the urge to vomit up everything inside, looked up at the slave.
That slave who was now looking down at her with an arrogant gaze.
"Y-you, rotten...!"
"Quite the strong pride for no reason."
The slave presses down hard... with his foot on the back of Juliet's head, who is clutching her stomach and bowing her head.
Forcing herself to endure the sensation as if her forehead were tearing, Juliet hides her face, contorted with shame.
"...Insolent... damn... slave... how dare you...!"
"You'll probably crave a cock like all the other sows anyway. It wouldn't be so bad to bestow it upon you first."
"...What?"
She barely managed to lift her head, but she didn't see the slave's face.
...Rather, something even sharper, yet thicker and larger...
Because the meat stick, no different from the slave's alter ego, loomed before her eyes.
"Service. With that venomous mouth of yours."
Kyuung...
Along with a prickling, ringing sensation in her lower abdomen, Juliet's heart raced...」
Yuri simply cannot understand the expression 'prickling, ringing sensation.'
Despite suffering countless defeats in sparring with her younger brother, she rarely felt pain in her lower abdomen while training in martial arts.
Because Adrian seemed to know without being taught that a woman's lower abdomen is a vital point and avoided it.
For such an Adrian to use the expression 'the lower abdomen prickles and rings'...
Especially since he doesn't use the expression of the lower abdomen 'ringing' just once or twice.
「...As if Juliet's lower abdomen still longed for that man's touch, it continued to ring...」
...It must mean there's some other point that only Adrian knows.
That was the conclusion Yuri's brain's delusional circuit reached.
And it immediately presented a hypothesis.
'Is this the reason why there are aftereffects when the lower abdomen, that is, the womb, receives a direct blow?'
Surely, when her swordsmanship teacher taught her, he only said the aftereffects were significant.
She heard it when she was young, but she definitely remembers this.
But if those aftereffects mean a rampage of sexual desire...
There's only one method left to prove it.
"...Get hit once?"
Yuri, hurriedly wiping away the drool from her lower lips that had been trickling down her thighs following her pussy, stood up.
\ \ *
Hoo, she relieves the fatigue in her muscles with a sigh.
Putting down the iron lumps she had been carrying all over her body, she lightly stretches.
Since her mana neatly resolves any strain about to affect her whole body, it's a rather meaningless activity.
As I've felt before, this body is more efficient than I thought.
If this world were a regular fantasy travel story instead of a Romance Fantasy, I probably would have taken down the Demon King even before coming of age.
"Adrian!!!"
...Of course, because this world is a Romance Fantasy, I can't even take down my sister, who is worse than the Demon King.
"Adrian! Are you here?"
"...Yes. Sister."
My sister, who kicks open the door to the training ground the moment she confirms my presence.
Judging by the fact that she's dressed somewhat comfortably, it seems she came after doing some official work.
"You, you wrote a new work, right?"
"Yes."
"Then why didn't you tell me?"
"...Huh?"
"No, I mean, I know you wrote a book last time, so why didn't you tell me? Don't you know how I found out about your writing last time?"
"...What on earth are you talking about?"
"That, I mean... Mr. Sade Zaharmacho? Why didn't you tell me your new work came out—"
"No, Sister. Aren't you having some strange thoughts?"
"...Huh?"
As if my words triggered something, Sister's face flushes bright red.
"Why should I inform Sister that I wrote a new work?"
"...Huh?"
"It's not a new work I wrote for Sister to see, is it?"
"......"
"Even though I started writing to show people—"
"Hey!!!"
Yuri, who gets angry first and asks questions later.
"I, I said I wanted to see that writing, is it, is it that difficult?"
"...I didn't say it was difficult."
"Just! Just let me see it a bit sooner, can't you? Huh?"
"...Do you want to see it?"
"That..."
She suddenly becomes speechless.
"...Ha, haa? No? Why would I want to see your writing or anything like that?"
"...You did until a moment ago."
"A moment ago was what! What!! It's just that I heard the writing my younger brother wrote became something sought after in social circles, so I was being supportive, so why!!"
"......"
"I'm just stuck in this tiny, cramped rural fiefdom as the acting baron, unable to do anything in social circles, waiting for time to pass as an old maid without even getting engaged, so can't I at least feel a bit better by reading a novel that's trending in social circles? But why do you keep trying to prevent me from even doing that and tormenting me? Really, I raised my younger brother wrong, I should have just sent him off at the Coming-of-Age Ceremony without even saying he looked cool, if I had just scolded him harshly since he was young, he would have asked for permission for everything, so this kind of thing wouldn't have happened..."
"......"
It seems Sister has more pent-up feelings than I thought.
Well, it doesn't make sense for her to be acting as the lord's proxy at a time when others would already be getting married and such.
I don't know what people from 21st century South Korea, who shout "girls can do anything," would think, but at least in this patriarchal Romance Fantasy worldview, a woman's best way to succeed is to marry well.
A baron's daughter could be said to have a somewhat successful marriage if she marries the son of a marquis or a duke.
Of course, marrying the Crown Prince could be said to be the most successful marriage...
'No matter how I think about it, that's impossible for Sister.'
This world is a Romance Fantasy. And the protagonist is a commoner girl, a distant descendant of a fallen noble.
Then who is the male lead?
Given that the Cinderella story has become a cliché beyond a trope to a standard in Romance Fantasy, the male lead in such a story can only be an incredibly wealthy man.
The Grand Duke of the North, the Frontier Count, the Monster Duke...
And the Crown Prince.
In this worldview, the man who ends up with the commoner female lead is the Crown Prince.
Moreover, considering that the Frontier Count and the Grand Duke of the North are all old, decrepit, or barbaric men, it can be said that Sister has no hope in that direction.
'Who would take her?'
If a sub-male lead were to be paired with her, they would. But it's clear those men wouldn't catch Yuri's eye.
Even if they are sub-male leads for a commoner female lead who might be a fallen noble, they can only be commoner sub-male leads, right?
There's no way Sister, who belongs to the particularly authoritarian side even among the nobles of this world, would like such a man.
"Understood. Sister."
"I just want to also... what did you say?"
"If a new work comes out, I should show it to Sister first, right?"
"...Really? Ah, no. That's not it... Hmph. Hmm, um... I mean, the reason I came is..."
Yuri, forcing herself to hide her good mood, opens her mouth.
"...Does hitting the stomach really feel that good?"
"......"
It seems Sister needs to study common sense more than marriage.
Still, judging by her suddenly bringing up the topic of stomach-hitting, I understand why she's acting like this.
"...Did you read the book?"
"Of course...!"
Yuri, about to say she obviously read it, but then hesitates.
Yeah, it's a bit awkward to say she read it so boldly.
Because it's a work that reveals desires too honestly, so if there were a publishing house in this world, it would have been cut immediately.
No matter how explosively popular it is, an embarrassing work is embarrassing.
"That... first of all."
"......"
"Do you know what hitting the stomach means?"
"...Yeah. Isn't that obvious?"
"What does it mean?"
"Female switch click?"
"......"
"......?"
Who on earth taught her to use such words.
"No, well... Juliet changes like that, and there's no other explanation, right? So I just—"
"Th-that, I get it, so could you please not speak so loudly?"
"...Why, are you afraid someone might hear?"
"If you know, please lower your voice."
"......"
The thought that I must correct Sister's twisted common sense came first.
After seeing my fiancée, who has the insane common sense that 'public exposure feels good' ingrained, I'm feeling that this is absolutely necessary.
"Sister. Hitting the lower abdomen means hitting a vital point."
"...Yeah. I know."
"And do you know why a vital point is a vital point?"
"......Because it's sensitive?"
"It's a bit vague to end with 'sensitive.' It's more serious than that."
"...Huh?"
"Hitting the lower abdomen alone can rupture the bladder. You might see blood in your urine, or accidentally get blocked and have to live in pain for the rest of your life. Moreover, it would be worse for a woman. The moment a physical impact is delivered to the womb, it becomes difficult to bear children. This isn't a vital point exclusive to women. The reason you panic when hit in the lower abdomen is also because of that."
"...Ah, no. But what you wrote—"
"Sister."
"...Yeah?"
"Writing is writing. Try to view it a bit separately from reality."
That day, Yuri's world crumbled.
\ \ *
Despite Adrian's very earnest explanation, Yuri had no intention of taking it at face value.
She was the one who had already reached a conclusion in her head. She only came to get confirmation from Adrian.
She didn't come to get lectured about cystitis or infertility.
'...I can't accept it. That hitting the lower abdomen just hurts?'
Yuri, who doesn't trust Adrian but trusts Adrian's writing.
It's a statement that reaches the height of contradiction, but since siblings are essentially each other's enemies, it couldn't be helped.
The problem likely lies with Adrian, who took this seriously.
If he had just said to Yuri, 'Yes. Everything Sister says is correct. Live your whole life talking about the lower abdomen being a female switch or whatever,' it wouldn't have provoked stubbornness.
Ironically, the sincere concern made Yuri act recklessly.
"...Again, you're just trying to enjoy it yourself, right? You think I don't know you sucked and licked with your fiancée at the Coming-of-Age Ceremony?"
Of course, no such news had reached Yuri.
Only the story that the Princess held her Coming-of-Age Ceremony, and the Empress, on behalf of the old and sick Emperor, offered congratulations instead.
It was too much to expect normal thought processes from Yuri, whose brain had melted after reading the lewd writing.
Frankly, Yuri probably knows too. That she's just making excuses by saying this. That it's all lies.
But since when did that matter?
"I too, I too will feel good...!"
She cannot forgive them for only doing pleasurable things among themselves.
Sitting astride her bed, Yuri slowly lifted her shirt and looked at her own lower abdomen.
'...Should I exercise or something?'
Suddenly, the bodies of the knights' brigade members come to mind.
Figures who trained relentlessly and became muscular masses regardless of gender.
Even if not to that extent, Yuri at least had the thought that she wanted to take care of her body.
How nice would it be to have firm abs.
Since she has no time to exercise now, should she just be thankful her belly fat hasn't swollen as much as her chest?
"...Hoo..."
Worrying about having no time to exercise is also brief.
For now, Yuri decided to carry out the act she had been longing for.
Lightly at first. She doesn't plan to hit very hard.
If she started like that from the beginning, it would leave scars and hurt.
Pang-
"..."
It seems she hit too lightly.
Next time, put a bit more force into it—
Puck-
"Eut..."
A sensation comes.
Not the prickling, ringing sensation she saw in the writing, but anyway.
She thinks it's a good sign that a sensation is coming from her lower abdomen.
She knows she shouldn't be satisfied with this.
Then, add a bit more force...
Pueok-!
"Eueut?!"
It's coming. The sensation is definitely coming.
This feeling as if there's truly a separate sensation in the lower abdomen.
If she hits a few more times with the same force like this...
Pueok-!
Once, twice, each time she hits her lower abdomen, an unbearable feeling surges from somewhere.
A feeling of wanting to erupt. A feeling as if everything will pour out.
If she just does a little more like this...
Pueok-
As Yuri's hand falls on her lower abdomen, the sensation she had been holding back until now pours out.
Pushshishishi...
"...Huh?"
...With urine.
And with real urine, devoid of any pleasure or anything.
"...Haa?"
Yuri de Vallancien.
Age 21.
She peed on the blanket with her eyes wide open.
