The Central Capital was celebrating.

Festival after festival, day after day, an unending chain of celebrations had taken mankind's largest occupation.

Just the year prior, the notion was unthinkably wasteful. When resources were scarce and the world was terrifying, such celebrations were reserved for the solstice. After all, just surviving for a year was hard enough when the overwhelming cruelty of demons roamed the lands.

Throughout the course of history, humanity was slowly being crushed down by the demons of the north led by their fearsome Demon King. It was said that over two thirds of humans had been wiped out by the Demon King's wars that had started hundreds of years before any current living human had been born.

As of a few days back, humanity was not struggling to survive but simply stalling the inevitable extinction of the species. For centuries, brave heroes had done their part in extending the deadline but none had come close.

Until now.

The Demon King had been defeated.

It should have been a trick. A desperate delusion. A foolish lie to boost morale yet the truth was that the impossible had been shattered by the hands of a party of four.

From the smallest orphan to the highest of royalty, the entire continent learned, no, needed to know how the world had been saved. In every home. In every tavern. In every street. The people would learn how to celebrate once more.

Himmel the Hero. Heiter the Priest. Frieren the mage. Eisen the Warrior. These four names would be whispered alongside that of the goddess herself. Every human would know the tale of the hero party who had vanquished the Demon King.

Yet, just where was the hero party now? Were they partaking in the many festivals that had spring up all across the continent? Were they staying in a high class inn or even at the royal castle? Were they eating out in a world where no one would dare charge them?

Currently, the heroes of the land were located in a small home located in one of the many small towns surrounding the capital. The home belonged to Eisen, the warrior of the party. It was simple and had the bare furnishings.

Even if the world outside was cheering and celebrating the dawn of a new age, there was a distinct lack of joy within the house. The atmosphere was solemn, as if whatever remained of the concept of Silence resided within the room. For a group who was toasted all over the land, there was a lack of joy within any of the four.

On one corner of the room, the dwarf warrior Eisen stood motionless. His expression was impossible to tell from how his long beard covered his face but the shadows under his eyes were not from the helmet he wore.

The elf mage Frieren was just as silent. The thousand year old who had the body of a young girl was sitting as she stared down at her lap. Normally, she was not one of many words but, since the Demon King's defeat, it felt more like she had droned out the world around her instead.

What truly mattered was what was going on between the two men at the center of the room. The priest Heiter was examining the hands of a sitting Hero Himmel.

Heiter held one of Himmel's limp hands, his own glowing with a blessed aura. "You really can't use them, anymore?"

Himmel shook his head, a tired smile on his face. At the moment, the hero would never wield a sword again. "I can still feel from them but no matter how hard I try, I can't move even my smallest finger."

"If you give me more time, we can find a way to heal them."

"My hands are the least of our concerns, Heiter." Himmel's reply got a small twitch out of the prone Frieren that went unnoticed by the rest of the party. "I would be willing to give up my arms, legs, and life, for the Demon King's defeat. What's really going on?"

Heiter sighed at his childhood friend's resolve. It always made him worry but that was also what made Himmel a hero. "I'm just making sure it's not related to the problem at hand."

No pun intended, of course.

"I got this injury while blocking that guy's final attack," insisted Himmel. His expression showed no regret, befitting his title. "I don't think they're related."

"That guy" of course referring to the Demon King.

Before the final blow was struck, the demonic lord made a final gambit attack directed at their party's mage. Out of desperation, Himmel blocked the attack with his bare hands before a final combination attack from Eisen's weapon empowered by the magic of Heiter and Frieren finished off Mankind's worst enemy for good.

..or, at least, that was what the world outside believed.

For there was no final attack.

On the verge of defeat, the Demon King tried to attack the mage Frieren by turning into a destructive ball of pure mana which Himmel blocked with his replica hero sword. When that broke, he used his hands. And when those broke, he used his own body.

When the remains of the attack cleared, only the hero was left standing. Heiter and Frieren immediately looked to see if Himmel was alive

The good news was that he survived with minimal injuries besides those of his hands. Suspiciously so for someone who had taken the full brunt of a Demon King Level magic suicide attack with their body. It was a miracle.

The bad news explained why it was not a miracle but a curse.

"I've confirmed it once more, and nothing has changed." Heiter's tone was as dead tired as its owner. "Just as before, demonic energy resembling that of the Demon King is residing within your body. In fact, it's only grown since his defeat."

The priest stood back up and adjusted his glasses. His usually slicked back hair was disheveled from how long he had been using his abilities to examine what was wrong with his friend.

They now believed their enemy's final goal was not an attack meant to kill but rather a magic meant to takeover the body of the one who had the greatest mana between the four of them, their elf mage.

When Himmel had blocked the attack, he had prevented Frieren's body from being targeted but instead replaced it with his own. However, the goddess looked to have intervened, as the hero's body was not taken over. The takeover magic was not prevented but, instead, somewhat alleviated.

Just now, Heiter confirmed there was only one location where he could feel the Demon King's presence in Himmel's body. With a tone not befitting of the crooked priest, he gave a solemn judgement of the Hero's situation.

"The Demon King is indeed sealed inside Himmel's Balls."

Heavy words that could change the fate of the continent resounded not across the world but within the tiny home of a dwarf sending dread through every member within the room.

Eisen was the first to speak, shaking his head with closed eyes. "How could this have happened..."

"Heiter, I ask you again." Himmel turned to his best friend with a gaze of utmost seriousness. "Are you sure we can't simply cut them off?"

It told the severity of the situation that both men were actually considering turning one of them into a eunuch for the sake of a brighter world.

"I'm afraid it's not that simple. It's not as if your testicles have become the new Demon King's castle. It's closer to say that fate and destiny have made your jewels a signpost for a future revival." Heiter denied the suggestion of self mutilation. "Even if we do cut them off, there's no telling if the energy would take hold of another part of your body...or even your very soul."

Eisen muttered an undecipherable sound, most likely a dwarven curse. "Tis' better an expected killer blow to the leg than a hidden assassination to the heart."

"I simply give pleasures up then." Himmel's acceptance into eternal virginity was without resistance. For a man who most likely could have any woman he wanted, abstinence came easily. "The Demon King will die along with my passions."

"That's the bigger issue." Heiter sighed. The knowledge the Goddess had illuminated Heiter with was oddly thorough but the priest was grateful nonetheless. "From what I was revealed, it's the opposite."

"What do you mean?"

"The longer your seed is allowed to settle and mature within, the stronger the power the Demon King becomes."

"So you're saying he needs to release it constantly?"

Perhaps, the demon king had targeted Frieren not because of her mana but due to her womb.

"The Goddess did not bless me with any specifics but I can guess at least once a week." The priest sighed. "Moreover, the seed would be filled with demonic energy so you need to be careful with disposal."

For example, if Himmel continually sowed his seed in the ground out back, a demonic plant may form from too much exposure. Especially with the energy of a Demon King.

For the first time since they arrived, visible frustration entered Himmel's face as he raised his unresponsive hands.

The hero just stared at them in concentrated silence. It took an eventual shake of the head for the party to realize he had been trying to move them.

Self-pleasure was out of the table unless he learned to contort himself in impossible ways.

With a self-defeated smile, Himmel lowered his hands back to his lap. "Well, I am a hero now. Surely, finding a woman wouldn't be so hard..."

"Aye," nodded Eisen. "There were plenty of lasses that trailed behind during the parade."

Indeed, even the princess has given him a flattering look when they arrived back at the capital, much different from when they started their journey.

However, the issue was still the demonic energy within the sperm. Would he simply say he preferred to finish outside for the rest of his life?

Himmel's perfectly balanced eyebrows scrunched together as one option entered his mind. "We can visit the hero sword once more. I may not be able to draw it but the holy barrier does repel demons."

Maybe, having sex in the freezing outside next to a Holy sword would help.

Heiter nodded, although it was clear this was mainly due to a lack of options. It would take quite a bit to travel back there but there was another reason to try their luck. "The chief may know something. She was also rather fond of you, if I could recall."

The tantric implication was basically an outright suggestion to fuck from a priest who should have had a vow of chastity.

A tired smile grew on Himmel's face. "If that's what you consider 'fond', my friend, then I wonder-"

"There is no need."

The three men turned to the final member of their party that had remained silent the whole discussion so far.

It was not as if they had been ignoring the elf mage, rather she had been the one drowning out the whole conversation.

Guilt had overtaken Frieren's mental capacities. If left to herself uninterrupted, the long lived girl may have stewed in such emotions for decades. However, a part of her mind kept up with the world outside and the current topic immediately took Frieren out of her inner turmoil.

With stoic resolution, Frieren stood up, turned to each other member of the party before landing on the sitting hero.

"I will take responsibility in making sure Himmel ejaculates to prevent the revival of the Demon King."

No one replied. All three were too shocked at the declaration to even think of a response. Sadly, Frieren took this silence as acceptance.

With a proud look on her face, Frieren continued. "Besides, my old master taught me a contraception spell. It should kill all the seed that entered my barren womb. An elf body would also resist mana better than any ordinary human womb"

"Um, Frieren." Himmel spoke up and Frieren had never seen his face in so much pain, even when he had saved her at the cost of his hands. "You do understand what you're saying, right? Have you even..."

"I've never felt the need however the situation is quite dire." That was right. This wasn't some romantic comedy, the fate of the world's peace was at stake. "I'll admit I won't be any good but I'll get better as we go along, Himmel."

Admittedly, Flamme never taught her anything more than the ultimate seduction technique and she never really needed to use it during her stay as a hermit hobo.

Frieren did vaguely understand that there was an inverse relationship between pleasure and the speed to reach sexual climax, where the more one increases, the other decreases.

Objectively speaking, a woman that was more trained in the bedroom or one simply more attractive with those big bags of flesh that often drew Himmel's gaze would work better.

But, this was the only way Frieren could make up for her mistake. It was the first time her own (lack of) action had caused someone so much direct pain. She was not a person without failure but this felt different.

Due to her own incompetence, Himmel had lost not only the use of his hands but also the chance to procreate with another. The thought sent stabs of pain through Frieren's heart.

Guilt? Sympathy? Anger?

It was impossible for her to identify such sudden emotions so quickly. Maybe, after a century of introspection, but time was, for once, not with her. The success of their mission stewed within Himmel's testicles.

Also, she could not imagine leaving the turmoil within her unresolved for even another day, what should have been a blink of the eyes in her own life.

Just how did humans deal with this?

Frieren saw a similar storm of emotions rage within the hero's eyes. Himmel bit his lower lip, clearly weighing the options on a choice the mage thought shouldn't have been one.

Just say yes.

The usually quiet elf found the blue haired man's silence more grating than any noise. That sad contemplating look did not match the Himmel she had gone on a ten year journey with.

What was there to even think about?

The situation called for a portable semen dispenser and Frieren was the perfect choice taking into account the immediate circumstances. While any other hole would do, surely, a familiar willing one was better.

Did Himmel not want Frieren?

Her pride as a woman had even believed that he would have jumped at the chance at having Frieren be his semen guzzler. She had no experience compared to a common slut but he did sometimes call her cute.

...did he now hate her?

The very idea pained Frieren in ways she never knew possible which was why she didn't want to believe it. It was illogical yet, the thought refused to die, instead continuing to eat away at her confidence.

After all, the Himmel she knew would not hold a grudge. It was his choice to protect her back then. He was a shining light, a person without hate but full of compassion.

The elf believed the heroic image born from her memories yet anxiety and the guilt born from her mistake forced her to realize just how little she actually knew about the people in this room.

Just how much did she know about Himmel?

Frieren had been wrong before which led to his disability. There was no reason she couldn't be wrong now. Everyone had their limits and perhaps Frieren had finally reached Himmel's own.

All she had to do was ask yet something was holding her tongue.

For once, there was an answer she didn't dare try to seek.

That was why...

"Himmel, let me handle your semen." Frieren knelt down and grasped one of Himmel's hands. It ached how it did not respond back, something that was her own fault.

"Frieren...I..."

"Please...," pleaded the young elf, squeezing the unresponsive hand even harder. She could not be left like this for the next millennium. She needed this path for redemption and freedom from the gnawing in her chest.

"..."

"Please, Himmel," begged Frieren, once more. She had lost many things but it was only now she realized there were some things she didn't want to lose.

"...okay. How can I deny the request of our party's intelligent mage?"

Frieren looked up to see the same kind smile she knew in her memories.

There it was, the Himmel Frieren knew. Himmel did not hate her. The Himmel in her memories was not wrong. Frieren was not wrong, she knew the man before her.

A torrent of relief washed away the pain within her. It was water for the lost in the desert, food for the starving.

It was the same hand that pulled her out of her inaction ten years ago.

"I won't let you down."

"You never do."

"That's not true," was all Frieren could murmur back as relief made way for fatigue to hit her small body. It was a rare case of emotional turmoil for her so, when it was cleared, all she wanted to do was rest.

Before long, she was already sleeping, resting her head on Himmel's lap.

The hero wanted to stroke the pale hair in front of him but Frieren wouldn't let go of the hand she had grasped. It wasn't like he could even stroke it with his other useless hand either.

He could only sigh fondly at the actions of the elf. Her misplaced confidence was charming as usual but Himmel did have reservations on having Frieren handle his libido management.

Complicated feelings Himmel believed he would take to his grave were now brought to the forefront by the elf oddly insistent in taking in his seed.

"It's a stopgap for now," said Himmel aloud, trying to ignore the pointed stares from Heiter and Eisen. Even he couldn't believe the words he had just spoken but he still needed to save face. "At the very least, until we arrive at the sword village."

The priest released a heavy sigh. "Fine, fine. I'll make sure to continue to look into this more but I feel like all of my earlier concerns were wasted."

Heiter then made a sign of the cross which for some reason annoyed Himmel, as if he was a lust demon that needed exorcism.

Eisen just smiled, spotting the curved smile in the sleeping Frieren. Compared to the earlier tense atmosphere, she was practically drooling on Himmel's lap.

"A sinful woman, indeed."

"The demon king has fallen. They have been sealed within the one who has bested them, the human hero known as Himmel...just as has been foretold."

In a dark room, concealed figures encircled a single round table. The only source of light came from above, illuminating the center of the table and yet none of the figures were able to see each other.

This was not just for show, of course. It wasn't like they expected to be watched or illustrated in a way that their identities remained hidden.

No, this lighting set-up was carefully chosen so none were able to recognize any of the others. Demons were fickle, and with the current loss of their king, alliances were as unstable as the weather.

Compared to the rest of the army, the physical looks of these seven were especially important in determining the magic they utilized.

After all, they were the Sages of Lust, the head demons in charge of keeping the rise of demonkind's population or, in a more extreme aspect, the ones who made sure they demons would not go extinct from natural means.

"So Schlact-sama was indeed correct. I'll make sure to let him know when I spit on his grave later."

"Fufu, I can't wait. Humans have such interesting mating habits."

"Tch. Who let this weirdo in."

"There's a reason younger demons have adapted the human form including such ineficcient reproductive organs. It's only natural their copulation methods would follow."

"But whoever gets their hands on the human, will give birth to the reborn Demon King. Or take such power for themselves."

"..."

"Oh, you looked quite interested in that last part."

"...On the brink of death, Humans ejaculate as a last attempt to pass on their seed. That's all there is to it."

"So there's no need for seduction then."

"But where's the fun in that? The shocked face of a human when you pierce them during their climax is tastier than any mana."

"Do what you all must, just know this is the same party who has taken the Demon King down. Whether the previous is revived or a new one rises, a leader will be born again. For the survival of Demonkind."

"""For the survival of Demonkind."""

AN: So I kind of wanted to write a Frieren who is wrecked with guilt due to her incompetence and explore a relationship where Himmel can be with Frieren but spurned not by love and maybe they could work from there.

...okay, fine. This was just me wanting to write a story about the DK sealed in Himmel's Balls ala the ancient manga Oretama/My Balls.

I needed to ruin Himmel's hands to prevent him from being able to jack off and I thought it'd be neat if that was Frieren's fault and it kind of spiralled out of control from there. I also find the juxtaposition of Frieren's emotional guilt with the whole thing being about Himmel's balls to be mildly funny.

I hinted at some OCs but you can bet some of our favorite demon sages will also show up to try to get a "stab" themselves.

I've been trying to do weekly uploads but I'm taking a writing break for Xmas and New Year's.

"Huh, they're going to name a day after us."

Heiter was about to turn to the next page of today's paper when he heard a noise. Flipping the top half down, he spotted an old man take the seat across the table from him. The codger had shriveled up skin that matched that of a prune.

No, wait. That was just Himmel.

"Didn't even wait for a day, huh?"

The clearly exhausted Himmel could only groan in what Heiter hoped was a tone of affirmation and not eroticism. Heiter, at least, placed a steaming cup of tea before the man who looked to have aged twenty years.

"Morning."

Heiter had to turn away as a blinding flashbang entered the room. If he wasn't careful, his glasses would magnify the light to boil his eyeballs.

"You're looking a lot better, Frieren."

"Hmm? I guess so," replied the elf nonchalantly, reaching for a piece of bread on the table. She then looked for some jam she could spread much like she did with Himmel's cheeks last night. "My head does feel light."

Heiter wanted to retort how her face was shiny enough to be seen at the bottom of a well but, instead, he decided to just get to brass tacks and ask the important question.

"So, how did it go?"

"Well," Frieren took a moment to bite into her bread and Heiter patiently waited for her to finish. "Losing my virginity wasn't so bad. We initially thought it wouldn't fit but with some creative applications of-"

"Stop." Heiter held up a hand to prevent both the continuation of the story and his own breakfast from leaving his mouth. " I mean the, hmm, aftercare, let's call it."

"Oh. The contraception spell worked. Killing the sperm was enough to nullify most of the demonic energy. It just takes a while for my body to absorb the cleansed excess mana. Here, you can check"

Frieren leaned back to reveal how her abdomen was clearly bulging, as if she was pregnant.

Desperately trying to keep his wits with him, Heiter slowly moved his hand until it was hovering over the round belly. "...well, it's true I don't feel any demonic energy."

The priest then withdrew his hand and tried to go back to reading the paper.

It was then he heard an oddly wet sound. His eyes were immediately drawn to a rapidly moving object sliding across the floor.

In a single frozen moment in time, Heiter and Eisen's gazes met.

"What are you doing?"

"I slipped."

The fallen dwarf then continued on his fallen way, ending the wordless conversation between the two.

"Frieren."

"Hm?"

"You are wearing underwear, right?"

From what Heiter could see, she was wearing a long white camisole that covered her body. He assumed, she was dressed up enough underneath seeing as her partner, as shrunken as he looked, still had clothes on.

"Himmel ate them." The elf's words were emphasized by Himmel taking an audible drink from his tea along with a satisfying exhale.

This was all then followed by the squeaking sound of a perpetual sliding warrior dwarf.

"I see." Heiter flipped the paper back over, making an honest attempt to ignore any questions or answers he had of the situation going on before him. He really did not want to throw up so early unless he had gone on a hard bender the night before. "Oh, there's a sale on potions for that shop down third street. We should pass by to restock."

"Himmel, I know you must be full after all you ate from my body last night but you must eat."

Groan.

Squeak.

"They really should do something about hurrying the southern wall repair job."

"Also, if you're still sore down there, I may have a healing salve I could rub. I'm sorry I thought I could fit a finger in there when the back could hold three."

Groan. Groan.

Squueeaak.

"It's just nice to see so much hopeful news after the Demon King's defeat. The people can now heal and live their lives."

"Also, I remember a number of spells related to mating such as appendage growth and sensitivity multiplication. I've never felt the need to use them but maybe we could try some in the future."

Groan. Groan. Groan.

Squuueeeaaak.

"Truly, a new time of peace."
