[The Unicorn's Horn and the Dungeon Master's Seed]

Men die because of curiosity. And if there’s a hole, one is bound to poke it. Perhaps the reason children get electrocuted by sticking metal chopsticks into electrical outlets is due to that very same curiosity—the urge to see what happens when you put something into a hole. Maybe that’s just the primal instinct of a male who needs to fill what is empty.

"Therefore, me sticking it to Amducias is an unavoidable, fated destiny."

"Master, who exactly are you making excuses to?"

"To all the Las in this world."

I am by no means a beast-lover. As someone who was once human, how could I ever be a horse-fucker? The term "fucker" is never used in a positive light, and such people are considered problematic both socially and conventionally. But those notions were merely remnants of my experience as a modern human.

"I need the teacher's help."

I decided to seek advice from a senior who had walked this path before me, just to be sure about having a meal with Amducias. Even if she wasn't a real horse, the size difference between a camel or a horse was negligible.

"...So, you're really going to do it?" Gremory let out a dry laugh, mocking me.

"You were the one teasing me about being a horse-fucker, and now you're going to do it yourself?"

"Yeah."

"You're so shameless it's annoying. I'll give you the conclusion first: there's no problem at all."

Gremory waved her hand ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠dismissively, trying to shoo me away.

"Why would it be a problem for demons to do it? Whether it's a Jocamel or a Unicorn, the only issues arise from size differences; there’s nothing inherently problematic about it from a demonic perspective. Honestly, I was the one who found it contemptible that you were doing it with humans at first."

"I see. So I was already a human-fucker."

I had nothing left to hold me back. The advice of the sage Gremory, who had cleared away my delusions, was truly a great help.

"And I was the one being fucked, not the one doing the fucking, so I don't know the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠details. If you're that worried, go ask the other demon girls."

"Aren't you just advertising that you're going to do it?"

"Then go and do it already."

I needed to verify if Gremory was pulling my leg.

"Master, you've already done it with birds, haven't you? Harpyia and Andras are both avian monsters." It was a sharp remark from Andras.

"Let's see. I've done it with a slime, a leopard beastman, and a tree root. Master, you're not even human, you're an Orc, so what's the problem? If anything, aren't humans the ones you shouldn't be doing it with?"

"I see. Was my common sense the one that was wrong?"

Thanks to Andras, I was able to reflect on my existence once more. For the final verification, I asked Shaitan, the demon among demons.

"Master, it seems you are worried about interspecies relations, but you have absolutely nothing to worry about. To explain it in a way you can easily understand..." Shaitan glanced at Ryun before answering me.

"If a human were to do it with a dog, that would be a disqualification as a human, but for an Altaic tribe member to do it with a Hispanic person is no problem at all."

"Ah, I understand perfectly."

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

It seemed the category of "demon" was far broader than my common sense could grasp. I, who claimed I would cover the four seas with Las, was crying "impossible" just because of appearances. I reflected on myself.

"The delusion has been cast aside. Let's go, time to fuck!"

I ran straight to Flauros's dungeon. Amducias had been left in Flauros's care with instructions to produce offspring. However, Flauros hadn't been able to eat, even though I had set the table for him.

"What are you doing right now!!"

I shouted at Flauros and the leopard beastmen. The tentacles of the Tentacle Drasil, which had come through the portal, had pinned the unicorn Amducias to the ground, but none of the leopard beastmen had been able to touch her.

"T-that is."

"All you have to do is mount her and fuck, and it's over, but you can't even do that?"

"H-her resistance is too strong..." one of Flauros's subordinates replied. I looked for Flauros and found him being nursed by Amur, who had returned to her original nest.

"What is he doing right now?"

"Ah, w-well..." Amur blushed but ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠looked at me with fear. The reason Amur avoided me was obvious, but I couldn't understand at all why Flauros couldn't eat the unicorn—ah.

"C-Commander." Flauros opened his eyes, lying in an awkward position.

"I have absolutely no sensation in my lower half... what happened..."

"Because the unicorn resisted, her hoof struck a very unfortunate place..." Amur said, looking tearful while glaring at Amducias.

I asked Flauros directly.

"Did you get kicked?"

"...Yes."

"Are you castrated?"

"...I haven't confirmed that far yet."

"Tsk."

I had chosen Flauros as Amducias's partner, but it seemed that was impossible for the time being. Flauros was a valuable asset as a combatant, but above all, I couldn't help but feel sorry for a healthy young man with such vigorous energy ending up like this.

"This, this. I have no choice but to take revenge."

I examined Amducias again. She was captured by our legion, her horn stuck in the ground, with her limbs held up toward the sky. It should have been easier to fuck her in her horse form than if she had transformed into a beastman like the leopard beastmen, so how did she manage to land a kick in such an unfortunate spot?

"You just have to go and poke her, right?"

"...W-well, I am a leopard beastman."

"Aha."

It seemed they were about to engage in beastly copulation, changed positions, and he got hit from bottom to top by a raised hoof. Regrettable as it was, I steeled my heart and approached Amducias.

"Hey. Why did you castrate my subordinate?"

"I-it's not confirmed yet, ugh...!"

"Forget it. Amducias, are you listening?"

"...I-if I'm going to bear a child anyway." Amducias replied with a face red as a beet. Even though she was a horse.

"I want to carry the seed of someone stronger...!"

"Ooh, well said."

Then I acknowledge it. I ordered the Tentacle Drasil to release the restraint of the tentacle branches.

"Change into your human form."

Amducias transformed from her unicorn form into a human with a horn. She became a girl with a much smaller stature than my chest, with an impressive yellow horn on her forehead. I briefly worried about whether I should put something on her since she was naked, but I decided to leave her as is, since she'd be undressing soon anyway.

"Hmm..."

Changing into human form made the resistance much less. But doing it just like that felt clearly lacking. If I were to do it with a horned woman, I would have done it with Shaitan long ago, and trying to put my thing into a place so tight it might not even fit would only result in pain.

'And sowing is impossible there too.'

Only the Flare Panther, a fellow beastman, could harvest fruit from the unicorn species. I had sent her to Flauros on purpose so that the Las would be the most efficient. I never imagined he would get kicked there and collapse.

"Is there no way..."

"Should I go ask Gremory?"

"No, if I'm going to ask, it's better to ask Shaitan directly. Ryun, bring Shaitan. She's probably training the succubi."

"Yes! I'll be right back."

Ryun ran toward the portal. To satisfy my immediate desire, I stood in front of Amducias once again.

"The oath of submission."

"...Chu."

Amducias pressed her lips against my glans. The sight of a beautiful woman, steeped in humiliation and defeat, kissing my glans never got old. I sat down roughly on the table in Flauros's room, and Amducias knelt before me, taking my glans into her mouth.

"Yeah. Suck and lick it hard."

Amducias began to serve my thing with awkward tongue movements. The motion of her small, rough tongue diligently wetting my thing with her saliva clearly had a unique sensation.

'But it doesn't turn me on.'

There was no heart to serve me with love like Ryun, no heart to try hard despite being clumsy like Eila, and no heart to give everything for me like Shaitan. The emotion of the act felt in Amducias's fellatio was by no means service.

"Haa, haa. How is it...?"

This was a struggle to survive. Las is supposed to be about mutual enjoyment and happiness, so how could I find any fun in this? I felt filthy for no reason, and the vigor in my thing, which had been standing, was about to subside.

'My horn feels like it's going to shrivel up, but her horn is piercing the sky.'

Perhaps she had some experience, as Amducias twisted her head and caressed my glans. Every time she did, her horn began to move here and there.

"...It's a control stick. Relax your head."

I grabbed Amducias's horn tightly with both hands.

"Since horses have long necks, there shouldn't be any problem, right?"

"Uup?!!?"

I pulled Amducias's horn inward. Naturally, my penis began to enter Amducias's mouth. The thing that entered her warm mouth pressed down on Amducias's tongue, passed her uvula, and bent directly into her throat.

"Uup, uup, grrph."

"If you want to live, hold on."

I reduced the force with which I held Amducias's horn. Amducias's head was pushed back slightly, but she began to breathe roughly through her nose, accepting my phallus into her throat to survive.

Sss, sss, sss. It was a rapid breath, reaching two or three times per second, and tears welled up in Amducias's eyes. Of course, she wasn't a monster weak enough to die from this much, and Amducias wasn't a good enough monster to deserve such consideration.

"How much pain did the ones whose virginity you took feel? Huh?"

I grabbed Amducias's horn again. Like a pilot grabbing the control stick of a fighter jet, I pushed and pulled Amducias's horn, teasing her mouth.

"I told you to relax."

"Uup, uuup...!"

Amducias seemed to follow my lead, but she kept tensing up. It seemed her muscles were tensing unconsciously due to pain and distress, but that only made me more uncomfortable. This isn't Las. It's just sexual torture.

"Sigh."

I pulled Amducias's horn back slightly. The glans, pulled out from her uvula, was placed softly on Amducias's tongue, and I used Amducias's horn as a handle to make her move it slowly back and forth.

"Hup, hup..."

Amducias's rough breathing began to subside. Because of the stimulation, which was less than even masturbation, I spent time slowly twisting Amducias's horn. I wanted Ryun or Shaitan to come quickly and show Amducias a happy Las overflowing with love.

"Hup, hup..."

But Amducias's reaction was strange. A blush began to rise on her white face, and the tension in her throat, which had been unconscious, began to loosen. After some time, Amducias left all the strength of her head to me, and she began to lick my glans slowly as if tracing its shape with her tongue.

"What is it. Do you hate hard play?"

"A-ah, I don't like pain..."

"And yet you were busy piercing other people's virginity?"

"..."

The horse-fucker issue wasn't the problem. It seemed I would have to fix her mentality firmly before I could use her.

"This won't do."

"What do you mean it won't do?"

Just then, Shaitan returned with Ryun. I was about to denounce the unicorn's double standard, but I asked about the system problem first.

"Is it possible to sow seeds with her?"

"Of course."

"No, I mean, she's castrated now. So is it possible to sow?"

"Of course?"

Shaitan and I looked at each other, tilting our heads for a moment. Something was definitely off.

"My point is... is it possible to sow with this unicorn? Other than the leopard beastmen."

"Of course. Only one existence. Only you, Master."

"...?"

"Ah." Shaitan clapped her hands and nodded.

"Master, come to think of it, you said you heard the explanation from Gremory. Do not resent Gremory. She must have assumed you 'would naturally know if you were a demon' and moved on."

"What is it."

"You must set the condition for the sowing target to Master—that is, the 'Dungeon Master'. The Dungeon Master can transcend species, but it is not set as a default value. Otherwise, Master... you are just classified as the Orc species."

"...?"

"Uh... so." Shaitan approached behind me and pressed the air with her finger several times. Aside from her chest touching the back of my head, I followed Shaitan's hand and moved the screen to change the sowing settings.

"...What is thisssssssssssssssss!!!"

"I assumed you knew..."

No one had told me.
