Chapter 6: Half-Demons
Fantasy Sex Story: Chapter 6: Half-Demons - When the Korean officer De-Yong is on the verge of dying in a duel against a samurai, a kumiho saves his life. She offers him a pact—one that can only be sealed through a union—and it heals his wounds. Too late, both of them realize the consequences of this bond, which also draws other powers onto the battlefield. In the process, the moral boundaries between humans and demons begin to blur.

Finding a fisherman to take them across the river had not been difficult.
De-Yong gave him a coin and they hurried back to the forest. His clothes were now stained with blood again. They would not be able to surprise the next patrol so easily.
De-Yong wasn’t worried about the soldiers’ bodies. The villagers would loot them and throw them naked into the river. There was also no fear that they would betray De-Yong.
Hopefully the path ahead of them was now clear. He would think about something for the way back.
Soon they had left the valley and reached the forest that hid them. To avoid any further unpleasant encounters, De-Yong suggested they return to the animal paths. Hesitating for a moment, Na-Ri finally agreed. After a short time, she chose a promising path, which they followed to a small clearing where they stopped. She immediately began to peel herself out of her clothes again.
Na-Ri couldn’t imagine regretting having to take these clothes off again. But De-Yong had called her his bride in it!
He stared at her in amazement.
“Why are you taking your clothes off again?”
With a slight regret, she folded the things into a bundle and tied them up. They were simply too impractical for her in the forest. Even just now, down in the village, the clothes had hindered Na-Ri in battle. Here, surrounded by branches and thorns, there were countless ways she could get caught. And tear them, of course.
“Because the clothes here in the forest are impractical.”
“All human women wear clothes in the forest!”
“People are stupid too.”
De-Yong turned away in a huff. A discussion with the demoness was obviously fruitless. Clothes were useful and, above all, decent.
“I need to eat something, my stomach is growling,” he changed the subject. “Let’s take a break for a moment.”
With these words, he opened the bag and looked inside. His expression became even darker.
“That’s all you left me?”
Reproachfully, he picked up half a rice cake. Not even enough for a meal.
Na-Ri didn’t understand the problem.
“Then take something else. Catch something!”
“Catch?”
“Yes, there are lots of animals here. Grab one!”
He stared at the Kumiho in disbelief. Was she mocking him?
“I can’t just catch any animal. I don’t have a bow and arrow or time to track them down. A hunt like this takes time!”
“Then it’s a good thing I’m with you, isn’t it?” laughed Na-Ri. “Wait here!”
Before he could say anything back, she disappeared light-footedly between the trees.
De-Yong stared after her in disbelief. What was she up to again?
He scowled at the half-bitten rice cake before finally eating it. At least it was something to soothe his growling stomach. It was unbelievable how hungry he was now. I wonder if it had something to do with his new strength.
When he thought back to the fight in the village, he was still amazed at how quickly and easily he had wielded the sword. He had almost been carried away by his own momentum. He had only managed to catch himself with a full turn of his body, hitting the second samurai with his momentum. That could have gone wrong. He had to learn to control his new strength.
Determined, he stood up and unpacked his weapons again.
His practice time was not too long before Na-Ri returned. She carried a small vampire deer under her arm and watched from the thicket for some time, undetected, as De-Yong hopped around the clearing with the captured sword, pointlessly splitting the air here and there.
What kind of game was he playing? But since he was waving his weapon around so wildly, she wanted to make herself noticed before she approached him, just to be on the safe side. After all, he could hurt himself otherwise. Humans were so jumpy and clumsy.
“I’m back, De-Yong!”
As expected, he was startled and jumped back half a leap, his sword outstretched in her direction.
Na-Ri stepped out of cover. Relieved, De-Yong lowered his weapon.
“What are you playing at? Are you fighting invisible air spirits? There aren’t any here!”
De-Yong grimaced angrily.
“I don’t play, I practise. My strength has grown and I’ve become faster. I have to learn to deal with it, otherwise I won’t be able to fight well when we meet enemies again.”
He bent down and put the sword back in its sheath.
Na-Ri threw the little deer at his feet.
“You could have made a small fire instead. Now you’ll have to eat it raw.”
“Raw? I don’t eat raw meat!”
Na-Ri shared the preference for prepared meat, but also ate raw meat. However, she had to eat raw blood in particular.
“Then I understand all the less why you didn’t light a fire.”
“How was I supposed to know you were going hunting? I thought you were getting other food!” he tried to defend himself.
“You humans are strange!” Na-Ri observed.
‘No,’ De-Yong thought as he set off to find some dry wood. ‘Demons are strange. Especially females!’
The preparation had taken longer than planned, but in the end De-Yong was full. The venison, although not even as tall as his hips, was of course far too much for one meal. Unfortunately, De-Yong had nothing to preserve the rest. He could still save a well-done piece for breakfast, but they would have to leave the rest behind.
The demoness had also eaten again. They sat together by the faintly smoking fire and stared into the embers. It was already too dark to walk any further.
“What did you mean by me casting a spell on the men?” she suddenly asked, pulling De-Yong out of his thoughts.
He hesitated for a moment and threw another piece of wood into the embers before answering.
“Your smile! It makes you even more beautiful! No man can resist you!”
“Is that what you mean?” She smiled again as she had in the afternoon.
“Uh, yeah, that’s what I mean. Can you please stop that?”
“Why?”
“Please Na-Ri!” he looked away, embarrassed.
“De-Yong?”
“Like what?”
“I see you are ready to reunite with me!”
Disgruntled, De-Yong ran after Na-Ri the next morning. She was using him!
Well, admittedly, it had been great last night, and again this morning. But she was using him! And he didn’t know what for.
As soon as he could think clearly for a moment, that is, as soon as he closed his eyes or could take his eyes off her, he imagined himself fathering little half-demons with her.
Seeing her shapely, bare bottom constantly in front of him as he walked didn’t make the whole thing much better. Because on the one hand he had this horrible idea, on the other hand another part of his body completely ignored his concerns.
Na-Ri, on the other hand, was unconcerned and happy in her thoughts. At the moment, she didn’t even care about getting to the temple. De-Yong saw her as his bride, that was all that mattered! But of course he had to introduce her to his parents. That was the right thing to do. So they walked on.
As they were largely walking on the crests of the hills, on elephant paths that had been used for centuries, there was no need for them to return to the valley and put on clothes.
They made rapid progress, although the paths rarely led directly in their desired direction. But they were so fast that detours didn’t matter. A horse would not have kept up this pace for long.
Accordingly, they came closer to their destination, and before they rested again in the evening, De-Yong was amazed at how far they had come.
“I know this place!” he said firmly, pointing to a small shrine that stood at a crossroads.
“It’s a two-day journey from here to my home!”
Na-Ri stood still.
“Well, let’s find a place to rest and eat something before we reunite. It’s about time!”
She picked up the bag with the unfortunate rabbit, which had had the misfortune to jump at their feet on the way.
“Is that enough, or should I catch another one?”
“A second one would probably be better. I’m really hungry again,” De-Yong replied. “Better two, then we’ll have something for breakfast too!”
The demoness threw him the bag.
“Good, then I’ll hunt something quickly and you find a suitable spot nearby and make a fire!”
Before he could say anything back, she was already gone.
Annoyed, De-Yong stood around indecisively for a moment. He hated it when she ordered him around. He was a man, and an officer at that! Nevertheless, he hesitantly followed the instructions because his stomach growled.
It really was time to get rid of the demoness.
He found a suitable place to camp not far from the shrine. The old fireplace proved that travelers had often stopped here.
It wasn’t long before the skinned rabbit was spinning on a stick over the fire. Then Na-Ri returned with her prey.
In fact, she had captured two more unfortunate rodents.
They were also quickly prepared and placed over the fire.
As they slowly cooked, De-Yong tried not to look at Na-Ri.
It was crazy: the longer he traveled with her, the more desirable she became. Even though he knew what she was. And when she smiled at him, his mind went blank.
“Na-Ri, would you please put your clothes back on?”
“Why?” she asked, puzzled.
“We are close to a road. And this storage area is obviously frequently used. Someone could be coming.”
“I didn’t smell any traces of samurai. Everything’s fine,” she said unconcernedly.
“I don’t mean samurai. I mean any travelers.”
“Oh. I keep forgetting how prudish you people are. Well, after dinner. And the union, of course! By the way: the first rabbit is cooked!”
Sighing, De-Yong took it from the fire.
‘Half-demons! A whole crowd of half-demons!” went through his head. But his one-eyed monk in the middle of his body didn’t seem to mind. On the contrary, he was happy again.
A rude awakening
Waking up next to the most beautiful woman in the world wasn’t bad at all. Moreover, when this unearthly beautiful woman even woke you up by sitting naked on your morning stand and starting to ride him gently, that was usually heaven for a man. At least, if the man didn’t know that a bloodthirsty demoness was riding him and, according to his assumption, trying to sire little monsters.
But the worst thing was: even if this man knew it, at that moment he didn’t care at all. She could even have sucked his blood at that moment and he wouldn’t have noticed because he was floating in a sphere that seemed beyond reality.
And while during a normal act with his wife he was able to fall asleep comfortably relaxed afterwards, here he longed for even more.
This frightened De-Yong to the depths of his soul as soon as his mind had somewhat reconnected with his brain.
He wasn’t quite sure, but that morning he had probably even told the demoness that he loved her! When he remembered this, he shook with horror.
With difficulty, he forced himself to remember that her current body was just an illusion. An artificial shell for a monster that ate people’s souls. And as a demon, she herself was without soul or conscience.
Remorse and desire for this demoness battled for supremacy inside him, but there was no clear winner. At least so far. So far, however, the demoness had easily managed to give his desire the upper hand at her discretion.
Without spiritual help, De-Yong was sure he would lose his soul completely to this demon.
Na-Ri, on the other hand, was happy. Their union last night, but especially this morning, had been wonderful again.
Before that, De-Yong had remained strangely uninvolved a few times, but now he had joined in again, kneading her breasts and ass, scratching and kissing her.
However, she had resisted his desire to kiss her on the mouth. He didn’t know it, but then her pearl would inevitably have returned to her.
But the most important thing was: he loved her, he had said so!
Full of renewed energy from the union, which she connected with her pearl in him every time, she now pounced on the remains of the rabbits. However, she also left some for De-Yong this time. After all, he needed his strength.
She had even put her dress back on for his sake. He was always so terribly nervous when she walked around undressed.
She had already finished eating when he sat down opposite her and began to eat the rest.
However, his relaxed, happy expression had already disappeared again and deep lines of worry spread across his face.
Na-Ri couldn’t explain it, but she simply blamed it on the strange nature of humans. Well, maybe she could distract him from his worries.
“Will we be staying at your parents’ house?”
De-Yong choked violently on the piece of rabbit and began to cough.
Na-Ri looked at him worriedly. How did people manage to survive if they choked so often while eating?
After a few coughs, he finally got his breath back and asked with a pained expression and hoarse voice: “What do you mean?”
“You want to introduce me to them. Are we going to live there together or do you have your own house? You haven’t told me anything about yourself yet!”
De-Yong looked at the remains of the rabbit in his hand and then threw it into the ashes of the fire from the night before. He had suddenly lost his appetite.
“Why do you think I’m introducing you to my parents?” he asked teasingly.
Na-Ri looked puzzled.
“That’s what you said yesterday: ‘Yes, we’re going to travel as husband and wife. We’re newlyweds and I’ll introduce you to my parents. Those were your words!”
He rolled his eyes.
“I meant that we tell this to the posts, and to other curious people, so that they don’t get too curious. When people don’t have an explanation for something, they start talking about it with others. Not everyone needs to know what we really are and where we’re going.”
Na-Ri’s face darkened.
“And where do we really want to go?”
Now De-Yong looked irritated.
“I thought we were going to the temple? That was your wish, wasn’t it?”
‘Oh, that’s right. It wasn’t really that urgent at the moment,’ Na-Ri thought to herself.
“I wanted to, but when you said you wanted to introduce me to your parents, that became more important.”
“Why?”
“Well, because I know that leading the bride home is an important ritual for you humans. And then we would finally be properly married!” Na-Ri explained, beaming with joy.
De-Yong’s face suddenly darkened.
“Na-Ri, we may be bound by a pact, but you are certainly not my wife! I am already married. I am not allowed to have another wife.”
“Then expel her, what’s the problem?” Na-Ri replied, slowly becoming annoyed.
“You want me to leave my wife because of you?”
De-Yong looked genuinely surprised.
“How could I do that? I love her. And we have a son together!”
Na-Ri tilted her head. She couldn’t understand the human feeling for children. As far as she knew, offspring were also just a kind of parasite that drained one’s strength and time. Strange that almost all animals were so attached to it. Well, even foxes weren’t completely free of it, but at least they were sensible enough to realize it themselves after a few months and drive the offspring away.
Kumihos, on the other hand, were infertile and had no such problems. Why have offspring if you were immortal?
However, she was experienced enough not to start a discussion about offspring with a human. She had often had such conversations in vain.
But to cite this parasite as a reason for not officially declaring her his wife was a bottomless impertinence. Her fangs involuntarily bared again and her eyes began to glow demonically once more.
“You said you loved me this morning! Was that just something you wanted to tell others to satisfy their curiosity?” she hissed.
De-Yong remained surprisingly calm in the face of the renewed danger of being mauled by her. She wouldn’t be able to hurt him, he was sure.
“That was an expression of passion. Not unusual for us humans. It doesn’t mean anything like that!”
Although De-Yong’s reflexes, strength and speed had grown enormously, it was not enough to dodge the demoness’s surprise attack.
She jumped at him, grabbed him with both hands and threw him several steps backwards against a tree. De-Yong clearly felt his ribs crack and an incredible pain spread through him.
He landed on the ground spitting blood.
And although he expected to die at the hands of the demoness, he began to smile: she would not get his soul! When she grabbed him once more and threw him around, he sank into a merciful blackness.
At the last moment, Na-Ri was able to restrain herself. No, she couldn’t kill him. At least not now. Not yet!
In her rage, she had half-transformed and her beautiful robe was hanging down in tatters. Disgusted, she stripped off the pieces of fabric and threw them into the still smouldering ashes of the campfire.
De-Yong left her lying there as he had fallen. If, contrary to expectations, he did die, it was all right. Then she disappeared into the forest. She absolutely had to kill something or someone.
When De-Yong regained consciousness, he was confused at first. Everything hurt and he had trouble opening his eyes because they were swollen shut. Slowly, his memory returned. The demoness had attacked him! But he was still alive. With difficulty, he lifted his aching arm and felt for the amulet on his neck.
“Slow down!” he heard an unfamiliar male voice.
De-Yong tried with all his might to open his eyes, but he couldn’t manage more than a crack.
In a blur, he recognized a monk crouching in front of him.
“You’ve been played badly,” he said.
“Who beat you up like that? It can hardly have been robbers, because your money and weapons are still there.”
“A kumiho!” De-Yong replied weakly.
Smiling indulgently, the monk asked.
“A Kumiho attacked you? And you’re still alive? How can that be?”
“Because I have angered her. But she can’t kill me because she has given me some of her power. Besides, my amulet protects me. She can obviously hurt me, but she can’t kill me. And she can’t move far away from me.”
The monk’s friendly smile suddenly disappeared. He looked around anxiously.
“The demon is still around?”
“I suspect so. I can feel her power inside me. She won’t be far away.”
The man hastily jumped up and turned away to run back to the path. If an angry demon was raging here, it was wiser to take to his heels. But a beautiful, naked woman suddenly blocked his path.
He noticed the glowing blue eyes too late as she grabbed him by the head and snapped his neck with a nasty crack. He fell to the ground, dead, where she bent over him and began to drink his warm lifeblood.
De-Yong had barely been able to look as quickly as he had. Moreover, his vision was still clouded. But what he had recognized was enough to make him shudder again.
He closed his eyes again. He was able to avoid the sight, but not the ugly slurping as Na-Ri sucked her victim dry. Only after a seemingly endless time did it stop.
Suddenly he felt hot breath on his face, smelling unbearably of blood.
“So you think I can’t kill you because of your amulet?”
A painful jerk on his neck told him that she had just torn off the amulet. Nevertheless, he kept his eyes closed. If she was going to kill him, at least he didn’t want to look into those demonic eyes again. Maybe he would keep his soul after all?
Once again her disgusting breath brushed over his face.
“I can and could kill you at any time, Na De-Yong. You can’t stop me. You should know that by now. But you’re stupid. We have a pact that I respect. That’s the only reason you’re still alive. But tease me one more time and I’ll strip your skin from your flesh alive before I eat your soul and spit it into the seventh hell! Do you understand me?”
De-Yong was undecided what to answer. If he agreed, would he agree that she could send him to hell? An all-pervading pain made him cry out. She was squeezing his testicles with her hand!
“Do you understand, Na De-Yong?”
“YAAAAAAAAAAA!”
The mountain spirit
It took a few more hours before De-Yong had recovered enough to sit up. In the meantime, Na-Ri had rekindled the fire and roasted a small antelope over it.
Her face had not completely transformed back into that of a girl, her fangs still protruding menacingly.
The monk’s body was still lying where it had fallen to the ground. Leaning on his elbows, half-erect, De-Yong watched the scene.
“Why did you kill the monk? He hadn’t done anything!” he asked with reproachful regret, because an innocent man had died because of him.
The demoness looked at him indifferently. The gleam in her eyes had not yet disappeared.
“I had to kill something, as angry as I was. And he came at just the right time.”
“But he was a harmless monk!”
Na-Ri jumped up in a flash, reached the corpse in three steps and turned it over. In doing so, she tore off the headdress, revealing long hair. She pulled a long dagger from a fold in the robe. She contemptuously hurled the dagger between De-Yong’s legs, where it penetrated the ground close to his manhood up to the hilt.
The whole thing happened so quickly that he didn’t even get a chance to get scared.
“That wasn’t a monk. He wanted to murder and rob you. At least rob you. When I came back, he kept the dagger hidden in his hand while he questioned you. He wears different clothes under his robe. And the blood splashes on the monk’s robe were not his.”
Contemptuously, she gave the corpse a push with her foot so that it skittered a step away. Then she squatted down in front of the fire again and continued turning the improvised wooden skewer.
“Besides, I don’t particularly like monks either. But their blood tastes just like everyone else’s. Now come on, the meat is cooked.”
Na-Ri behaved as if nothing else had happened. This frightened De-Yong even more. Although he didn’t feel any appetite, he forced himself to get up and carefully walked over to the fire.
He had to eat something, at least that’s what his stomach demanded.
“Are you full?”
Na-Ri looked at him questioningly.
De-Yong nodded and threw the gnawed bone into the fire.
“Then let’s reunite, it’s time!”
“I don’t want to!” De-Yong objected.
Na-Ri was genuinely astonished. In a thousand years, she had never heard a man offer to do that to her.
“You don’t want to?” Her voice took on a dangerous undertone.
“You can’t beat up a person, almost kill them and then expect them to make love to you! It doesn’t work like that.”
“I’m not talking about making love. We should just unite! And whether you want it or not doesn’t matter: it’s necessary! Besides, it’s always given you pleasure so far.”
“Yeah, uh, no,” De-Yong began to jerk around. “In a way, yes, but it’s not the same as when people do it. Especially voluntarily. Why is it even necessary?”
“Our pact is that you give me your knowledge, not me giving you mine,” she reminded him. “But be that as it may: you carry my power within you. The further I distance myself from you, the weaker I become. However, if I take in your seed, which was created with my strength, it will give me strength. Then I have a supply and am not dependent on constantly being in your immediate vicinity in order to access my power. And now take off your clothes!”
“So it’s not for the purpose of you wanting to sire half-demons with me?”
Na-Ri’s expression changed from surprise to disgust.
“But no! Why would I want that? Who wants half-demons?”
De-Yong looked at her suspiciously. Was she telling the truth? To distract himself, he pointed at the monk’s corpse.
“And that one is annoying too. He keeps reminding me what you are. That scares me.”
“He obviously didn’t bother you at dinner.”
“That’s something else.”
“Why?”
“That’s it, done!” De-Yong replied indignantly.
“I just can’t get it up anymore!”
Na-Ri furrowed her brow. She looked at De-Yong thoughtfully.
“Did I break it?”
“What? No! I just can’t because you’re scaring me! Don’t you understand?”
“Oh.”
Both looked thoughtfully into the fire. Finally, Na-Ri raised her head again.
“Would it help if I made my fangs disappear again and smiled like I did yesterday?”
“Um, I think so,” De-Yong stammered in surprise.
As if nothing had happened, she smiled at him.
Yes, yes, it helped, he realized. Then another part of his body took control again.
They had lost a whole day due to De-Yong’s injuries before they were able to set off again.
But as serious as the injuries had been, after two days De-Yong no longer felt any of them. It was really amazing how quickly he healed.
There was now a kind of truce between the two. Both wanted to go to the temple and therefore came to an arrangement. The daily union was more of a duty than a passion for both of them. But it was always satisfying for Na-Ri. It was simply an indescribably exciting feeling to regain her power in this way. De-Yong’s reticence annoyed her, however. She would be glad when she got her pearl back.
The last leg of their journey was unspectacular, apart from the fact that Na-Ri was now wearing the clothes of the fake monk. As they were traveling on official routes, they encountered so many other travelers that a naked girl would have attracted too much attention.
Strangely enough, De-Yong didn’t even have to urge Na-Ri to take the clothes and then even put them on. A simple hint had been enough. She obviously seemed capable of learning.
In fact, Na-Ri had a vested interest in walking around in disguise. They were approaching the Temple Mount, and thus Cham’s territory.
Cham was a dokkaebi, a mountain spirit. Mountain spirits were usually friends of mankind and in the worst cases played nasty tricks on people. But then the victims deserved it.
Anyone entering the territory of a Dokkaebi was well advised to make a small offering. For this purpose, small shrines were usually build in appropriate places.
But in Na-Ri’s case, a small offering was not enough, because she had a history with this particular mountain spirit. It was likely that he was still quite angry with her.
And since mountain spirits were secretive, attentive observers and listeners, it was good if their presence in his area was not publicized.
Therefore, she had not only complied with De-Yong’s request for clothing, but had also tried to disguise herself accordingly so that Cham would not recognize her. With many other supernatural beings, she would have no success because they could see through her disguise immediately, but mountain spirits were quite limited in their perceptions. If she also hid her hair, she would be sure to get to the temple unmolested.
At least that was their thinking.
It was late afternoon when they reached the foot of the mountain. A shrine marked the boundary of the mountain spirit.
De-Yong paid no attention to the shrine. He was not a traveler on his way through the area, but a pilgrim on his way to the temple. He had never asked for the goodwill of Dokkaebi before. He was accordingly surprised when Na-Ri, of all people, stopped there to make an offering.
“What are you doing?” he asked in amazement as she placed a roasted piece of rabbit in the shrine.
“I’ll abide by custom and pay my respects to the mountain spirit!”
“Does a Kumiho need that?”
“Shut up! Don’t call me that, ever again, all right!” she hissed at him angrily. “I’m Kim Na-Ri!”
Startled, De-Yong backed away. What had he done wrong again? Another one of Kumiho’s whims that he didn’t understand. But he didn’t want to risk another thrashing.
“Yes, that’s all right. If you wish, please do! Kim Na-Ri, my mistress!”
Her eyes glared angrily at him, but the demonic glare failed to materialize.
“Go ahead, I’ll follow you properly,” she ordered him. “But walk slowly!”
Shrugging his shoulders, De-Yong did as he was told. Well, hopefully he would soon be rid of her.
The path was steep. But thanks to his new strength, De-Yong made very good progress, although he tried to walk slowly as instructed.
When he thought about it, he regretted that he would lose his powers again along with Na-Ri. You could get used to that. Besides, they were very useful for him as a soldier right now, during the war.
Suddenly the ground gave way under his weight and he slid sideways down the steep slope. Sliding on muddy ground, he found nothing to hold on to. He also saw the small cliff in front of him too late.
With a yelp, he slipped over it and landed about 10 steps below in a swamp, where he sank with a loud splash.
