"Phew… What a crazy turn of events that was."
Looking up at the clear blue sky without a single cloud, I muttered those words to myself.
I was inside a carriage, staring out the window at the scenery passing by.
A sudden summoning to another world, my appointment as the 'Seiou' (Sex King), and then the engagement.
But soon after, the truth that 'Seiou' actually meant "Sex King" was exposed, leading to my engagement being called off and, effectively, my exile from the kingdom.
Honestly, if Princess Elissia hadn't stepped in, exile might've been the least of my worries. I might've been executed on the spot, from bottom to top. I found myself glancing at the girl sitting right in front of me, thinking about that grim possibility.
Sitting across from me was Princess Elissia herself, along with a calm, intelligent-looking woman in her mid-twenties, dressed in men's clothing, silently observing me.
"We'll be passing through a checkpoint shortly. I'll excuse myself for a moment."
The woman in men's clothes, her name was Mia, the princess's aide, got out of the carriage.
"Finally, we're alone. There we go."
As soon as the door of the carriage shut, Princess Elissia stood up, gathering the hem of her dress, and sat down right beside me.
The inside of the carriage was small, so naturally, her body pressed up against mine. A sweet, floral fragrance, likely her perfume, tickled my nose.
(Seeing her this close… she really is unbelievably beautiful.)
Her shimmering silver hair, streaked with hints of soft pink, created a mysterious beauty. Her eyes, a vivid ruby-blue, sparkled with life. Her skin, smooth like polished porcelain, radiated freshness and vitality. She wore an elegant dress, the kind a medieval princess might wear, managing to balance grace with luxury. Even the slight glimpse of her modest chest carried a strangely mature allure that didn't match her youthful appearance.
"We've crossed the border now. It won't be long until we arrive. My country is quite small, after all."
"…By the way, why did you move over here to sit next to me?"
I honestly had no idea why she went out of her way to squeeze into the small space beside me.
"Oh, I thought men liked things like this," she said innocently.
The princess pressed her soft body against me, her chest and hips touching without hesitation. Even through the fabric of her dress, I could feel the firmness and elasticity of her young skin.
At the very least, this princess didn't seem to fear me at all. She looked nothing like the dignified girl who had taken me in, instead, she now wore the innocent expression of a girl her age.
"Are you really okay getting this close to me? I'm known as the 'Sex King,' so feared that they say, 'Just meeting his eyes could get you pregnant.'"
"You don't need to worry about that," she said with a gentle smile. "Besides, in our country, it's a tradition to offer 'love' to men in need."
With that, Princess Elissia began to tell me an old legend, the founding story of her country, the Kingdom of Freesia.
"Five hundred years ago, visitors from another world came to five different nations in this world. These visitors used the 'magic' granted to them by the Supreme Rulers who ruled our world and shared advanced knowledge from their world. Thanks to them, four of the five nations flourished.
But the fifth visitor was different. He struggled to adapt to this world and chose to live alone in isolation."
So this kind of thing had happened even five hundred years ago. No wonder the technological development of this world feels oddly mixed.
"The Supreme Ruler of Love, Freya, was concerned about this. She ordered a temple maiden named Freesia to visit the lonely man. For three days and three nights, she stayed by his side, serving him with devotion... and eventually gave herself to him."
That escalated quickly. This founding legend of the country was far more 18+ than I had expected. Three days and three nights, huh… that's some really awesome stamina.
"Through Freesia's sincerity, devotion, and kindness, the man finally opened his heart. She opened his body… and through that, opened his heart."
This… sounded strangely like the kind of story an old man would come up with.
"Once his heart was open, the man donated a great fortune to the temple and agreed to use his magic and knowledge for the sake of the people. He moved to this land with Freesia, became the first king, and together they founded the Kingdom of Freesia, named after her."
"The first king used his magic and knowledge to discover two mystical springs."
"The first was the 'Spring of Purification,' a miraculous spring that could cure all sexually transmitted diseases."
"Only sexually transmitted diseases…? That's… oddly specific," I muttered.
I couldn't really tell if the goddess Freya was impressive or just weird....
"The second was the 'Spring of Beauty,' a spring with the power to preserve youth and beauty."
"Now that's impressive," I admitted.
"Yes. People from distant lands came seeking its blessings, and the kingdom enjoyed great prosperity. At its height, the capital's population exceeded 100,000."
"But two hundred years ago, the Spring of Beauty began to dry up. And by a hundred years ago, it had completely vanished."
"…That's tragic," I said quietly.
"Fortunately, the Spring of Purification still remains. So the temple maidens, following the example set by the first temple maiden Freesia, offered themselves to men in exchange for rewards, doing whatever they could to sustain the nation."
"Ah… so that's why Freesia is called a 'Prostitution Kingdom.'"
So that's why Princess Katua and the others looked down on Elissia's homeland and called it a nation of prostitutes.
"But even with all their efforts, it was still difficult for the kingdom to survive."
"And so, the kingdom's beautiful Princess Elissia made a decision… to welcome the 'Sex King' from another world, a man feared for his overwhelming power, into her country, and to save her kingdom through him."
She casually referred to herself as "adorable," but honestly, she really was. So I couldn't bring myself to argue.
"Even if you say it's necessary, I'm still not entirely sure what I'm supposed to do."
"'Sex King' is just a nickname for me right now."
"All you need to do is serve as an advisor to the girls at the Meikan. Of course, we would also appreciate it if you could help them with... practical training..."
"P-Practical..."
"I'll explain the details later, but I believe it will be something very enjoyable for you as well, Lord Seiou."
"Hmm..."
Summoned to another world without warning… then having my engagement broken and getting exiled… and now being asked to guide a brothel? Everything was happening so fast that my mind was struggling to keep up.
"There's no way for me to return home, is there?"
"I'm afraid not. At least, I do not know of any such way."
That meant I had no choice but to live in this world for the time being. There was no other option available to me.
"I'll be counting on you, Princess Elissia."
"Of course. It will be my pleasure. And please, just call me Elissia, or simply Ellis."
"Ellis, huh..."
"You may even drop the formalities and call me that casually, big brother."
"...Huh?"
She suddenly called me "big brother."
Could it be… was she actually my long-lost sister?
Before I could even process that thought, Ellis clung to my arm like an affectionate little sister.
"Or would you prefer if I called you 'onii-chan' instead?"
"Why 'onii-chan'? Am I really supposed to be your brother or something?"
Was she about to reveal some shocking truth that my parents hid forever?
"No, not really. But I heard that in your world, men often 'like' it when women call them that..."
So it was just some sort of 'pretend sister' game.
Where on earth did this princess even learn about things like that? Well, at least it didn't seem like we were actually related by blood.
"Or would you rather I call you 'Sensei'? Teacher..."
This time, she looked up at me with innocent yet seductive eyes, like a student teasing her teacher.
"I'm not a teacher though."
"But you will be teaching the girls of our nation... teaching them about 'sex education'. So I thought 'Sensei' might suit you."
"...Ugh..."
Sex education, huh...
"Or perhaps I should call you 'Master' instead? After all, you'll be 'training' the girls of our country..."
"Ugh..."
Her playful tone, the way her soft lips formed those provocative words, it all struck me like a volt of electricity running through my body, freezing me on the spot.
"I heard men from other worlds like being called that, Master~"
Where in the world did she get all this information?
"...Don't call me that."
"You sounded like a robot just now, how amusing. Then it's decided. I'll call you Master from now on."
Why does she even know the word "robot" was there also a chinese version of elon musk here?
Something was bubbling up deep inside my chest, something hot and dangerous.
"Stop it..."
"Master, I'm counting on you. Not to just 'educate' the girls at the brothel, but to 'train' them as well."
With Princess Ellis smiling so radiantly at me, that burning feeling inside my chest grew even stronger....
Until..... It finally exploded.
