The Blue Demon's Submission
Eos lay upon the slave bed, lips pressed into a thin line as she fought to endure. Having never experienced sexual pleasure before, she seemed to instinctively sense the danger it posed.
"Eos. Do not hold back."
"Ah..."
Seeing her clench as though in pain, I gave the order. "Feel it exactly as it comes."
With the slave mark upon her, Eos had no choice but to obey my voice absolutely. The expression that had tried to resist my touch slowly melted away. Her face relaxed, freely accepting the contact.
"Aah... ah..."
I could see the tension leaving her body, the one she had bound with her own will. A desperate plea reached my ears.
"I... I don't want to lose myself..."
"I bought you. You asked me to buy you. You even swore to serve me as your master."
"Hic... hicc... ugh..."
"Keep the oath you made. If you truly want revenge on the Silver Demons."
"Hic... yes."
The blue demon who had looked unbreakable through any torment now shed tears. She must have known this moment would come, yet seeing herself powerless before it had broken something inside her.
"Hic... Please make me your slave, Master."
"Very well."
Eos spread her own legs. She opened her entire body to make it easier for me to enter. All I had to do was claim her.
"Ah... aah..."
Remembering my words, she no longer fought the pleasure. Tears streaming down her face, she committed every caress to memory. My marks were left upon her copper skin. Wherever they faded, I appeared again. At some point, I pushed inside her precious entrance.
-Squelch.
"Aaaht!"
The heated woman's body cried out in ecstasy the moment I entered. Her insides were pierced and clamped down on me with ferocious strength. Even as a virgin, she was feeling me completely. Women of this world had no choice but to love men. No matter how strong Eos's will or how fiercely she tried to resist, this truth was carved into her very being.
-Squelch... squelch... squelch...
"Hah... hah... haaaah..."
The female demon continued to prove it with every moan. That she had become my slave. That she acknowledged me as her master.
"Please use me however you desire, Master."
I had not ordered her to say that. The words rose from Eos's own heart.
"Thank you for granting my request...! Thank you for giving me warm clothes and food...! Hic... hic... So, so...!"
The blue demon looked up at me with a broken cry.
"Please accept me as your slave...!"
"I will. And I will help you with your revenge."
-Squeeze... glorp... glorp... glorp...
Eos reached climax from the heat she felt deep in her womb. Remembering everything she had felt and sworn, she renewed the slave contract. Mana flowed between us, passing from one to the other.
"Ugh... uuuugh... ngh..."
Eos's wounds were visibly healing. The hole in her stomach closed without a trace. The eye that had been blinded regenerated. Even her broken horn rose cleanly once more.
You have learned Water Magic.
Syucali approached me right after the notification of my new ability.
"As expected of Master."
She had appeared beside us and witnessed Eos being healed.
"Don't speak of this anywhere."
"Of course not, Master."
The mana seals the human hero had placed all over her body were still there, yet Eos had returned to a flawless, unblemished state.
-Squelch...
When I pulled my cock from her pussy, traces of red blood were visible.
"I'll clean it."
"Go ahead."
Syucali brought a white cloth and wiped my lower body. As a finishing touch, she spread her lips and sucked me clean.
"No more blood taste now."
Syucali sent me a seductive look.
"You're such a lewd one."
"I'm sorry, Master."
Syucali smiled as she grabbed my cock and shook it. She opened her mouth again, taking me in and sucking.
"Hoo... haa... I've become addicted to you, Master."
"Don't get addicted."
"Yes, Master. Hehe... Though I'll probably get addicted again soon anyway."
I had recently discovered something. The absolute obedience granted by the slave mark was not truly absolute. Syucali, who kept sharing my bed, was the perfect example. I had ordered her to stop after she kept approaching me with sexual advances multiple times. Yet the next day she would get excited and pounce on me just like this.
"Next time, try hating me."
"Yes, I'll do my best to hate you, Master. Hauup... slurp... slurp... slurp."
Should it be called sexual desire that overcame absolute obedience? I was running various experiments, but I had a feeling they would all fail in the end. Still, since I needed to raise Syucali, I had no intention of stopping our activities. I came in her mouth and filled her pussy with semen until it overflowed.
Since I had to leave this village with Isabella tomorrow, I needed to prepare thoroughly.
"Lord Kang Seo-ja. You're incredible."
"What is?"
"Your performance in bed."
"You're saying the same thing as yesterday."
Syucali looked at me with a blissful smile. Even though she had collapsed from exhaustion, there wasn't the slightest hint of displeasure on her face.
"Please keep using me until you're fully satisfied, Master. I can't move anything except my fingers now."
She even spread her pussy with two fingers, showing me how the semen gushed out.
"Don't think you're my only slave."
"Ah... that's right."
Syucali's gaze turned toward the blue-haired demon beside us.
"Ah...! I'll prepare right away..."
Eos, who had woken up at some point, was touching her newly healed body. When I looked at her, she realized it was her turn. She spread her legs and assumed the position.
"Please use me until you're satisfied as well..."
Eos's face was already flushed crimson. She looked exactly like a woman who had tasted a man for the first time.
"Good."
I moved without hesitation. From a man's perspective, there was no reason to avoid sexual activity. I would embrace my slaves again and again, raising them both.
"Lord Kang Seo-ja... isn't that a bit too big?"
Syucali's comment came as she saw the backpack I carried out of the hideout.
"We don't know how many days we'll be wandering. This much is necessary."
"Still..."
It was nearly three times the size of her body, so it certainly stood out.
"It's not heavy, so don't worry."
"Ahaha... understood."
Syucali gave an awkward laugh, clearly unable to comprehend.
"Where are we going?"
"I've been hired by Isabella's trading company. We'll be traveling for quite a long time."
"Traveling... I see."
Eos had only become my slave yesterday, so she must have been bewildered about suddenly heading somewhere today, but it couldn't be helped. When I gave an order, she had to obey.
"I heard you were on the battlefield."
"Yes."
"Can you carry out any kind of mission?"
"The reason I was betrayed was probably because my abilities were deemed that threatening."
"An ability strong enough to make even her own kind betray her..."
The water magic I had obtained from last night's activities.
"Is water magic really that powerful?"
"Water magic... Did you already know about it?"
"No. I simply possess an interesting ability."
I opened my palm and concentrated mana. I had thought that to manifest magic, one only needed mana. But that wasn't the case. To use magic, one needed talent. Either the genius talent of a mage, or the innate talent one was born with, like the demon race.
Because Eos was from the Blue Demon family, her affinity for water magic was beyond imagination. I, who fell short of that talent, could only manage this much.
"Water Ball."
It was a droplet about the size of a face.
"It's magic."
"Merely an imitation."
"Don't tell me... you copied my magic?!"
"That's right."
"H-how is that possible... The Blue family's magic isn't something you can simply learn...!"
"It connects to one's ancestors before birth."
"!!"
"Demons cannot steal another demon's magic. No, no being can steal the magic of the Seven Great Demon Families."
I erased the water droplet from my palm and walked forward. Syucali followed me. Eos came to her senses late and hurried after us.
-Splash... splash...
When I learned water magic, I realized something. What I had gained was nothing more than a small asteroid in the vast universe. That was why I needed to keep sleeping with Eos. Even if I held her for a lifetime, I doubted I would ever see the end of the Blue Demon family's potential.
"A fine slave indeed."
"Pardon?"
It also meant I could continue growing alongside her.
"May I ask how you are able to use our family's magic?"
"Stay by my side and find out."
"...Understood."
For now, I had cast the bait. With her body healed, Eos could have broken the slave magic and fled at any time. I needed something else to bind her, something beyond the slave mark. That shackle was the water droplet known only to the Blue Demon family. The very Water Ball I had just shown her. The shock of a human creating it must have been immense.
The crest of the Blue Demon family.
The droplet I had shown was no ordinary Water Ball. At the end, a blue pentagram had appeared inside the droplet. Eos had flinched at the sight.
Demons are similar to humans, they say.
Then their curiosity must be similar as well. Since she could leave anytime for her revenge, she would likely think it wouldn't hurt to learn more about me before departing.
"Lord Kang Seo-ja, I can see the trading company's carriages."
Where Syucali pointed, I saw what appeared to be Isabella's company personnel.
"It's impressive no matter how many times I see it."
As she said, dozens of carriages lined up in a row was truly a spectacular sight. It was not a scale that could come from a small village. Now I understood why Isabella was called a master merchant. And that the hundred gold she had spent on me was probably nothing to her.
