Chapter 6

“Haa… Haa… Ngh…! Ahng, hah…”

His hips rose and fell in an endless rhythm. Drenched in sweat, Leonhardt straddled the monster’s body, driving himself solely in pursuit of the sensations that could soothe his body.

The heavy cock thrust upward into him with a wet slurp. Ravenously swallowing the thick red cudgel, his entrance stretched to its limits, eagerly milking the fleshy pillar as it spewed clear fluids.

“Ah, ngh, haa… Ah, it feels so good…”

Straddling the monster and taking its cock, Leonhardt sank down. Grinding his hips back and forth, he let out a breathless sigh as he shamelessly enjoyed the deep, dull friction.

Desperate to further chase the electrifying sensation spreading from the base of his spine all the way to the crown of his head, he continually lifted and dropped his hips, each plunge drawing wet, squelching sounds of copulation.

Why had he refused to admit it all this time? That there was nothing quite as euphoric as the heedless pleasure granted by a monster.

Ever since being abandoned by his men, Leonhardt had coupled with the monster as though he had truly fallen into a hell of perpetual mating. Sometimes he was ruthlessly violated and filled with its seed even in his dreams. Waking to find his body being roughly shaken, still impaled upon that massive cock, was a regular occurrence.

In the past, the entire ordeal would have sickened him, but now, his mind was entirely blank. It was far more accurate to say that, thoroughly steeped in endless stimulation, he had lost the ability to think at all.

He no longer needed to agonize over the safety of his men. He didn’t have to involve himself in the nobility’s tiresome political battles, nor did he have to throw his own body on the line to save people.

He didn’t have to grieve at the sight of innocent children suffering, nor did he have to clash with corrupt priests who violated their doctrines to commit immoral acts.

All he had to do was drown in the pleasure Kelles provided, gorge himself on demonic energy, and lie back comfortably. As long as he carried its young dutifully, the monster never forced him to recite scriptures, nor did it demand he wake before dawn to pray and take up his sword.

“Aah…! Ah, Kelles, Kelles…”

His body locking through a light climax, Leonhardt collapsed forward, gasping the monster’s name. He could feel his jaw and chest sinking into thick, plush fur.

Sweat cooled on his skin as he lay flat against the soft fur coating the monster’s body, a cool breeze settling over his back and bringing a wave of deep languor. However, he couldn’t simply lie there limply. Having not yet reached a truly shattering climax, Leonhardt raised himself like a man possessed and began rolling his hips once more.

Does it really feel that good? It is quite pleasing to see you being so honest.

Seeing him slam his hips down to squeeze out even a fraction more pleasure, despite his heavily pregnant body, was undeniably arousing. Looking up at the chest bouncing rhythmically above it, Kelles leisurely admired the human’s desperate movements.

Few things were as enjoyable as finally getting one’s hands on something deeply coveted. Branded with its mark, carrying its spawn, yet still squeezing his hole tightly in sheer insatiability—the human was almost cute.

Squelch, squelch.

After grinding his hips a few more times atop the beast, Leonhardt panted exhaustedly. Though he could take it deep, a human simply couldn’t replicate the explosive movements of a monster. To be ruthlessly skewered exactly where he wanted it, he ultimately needed the beast’s help.

“Ah, I want… to cum now… Husband, please fuck me with your cock…”

By now, Leonhardt had zero hesitation in spitting out the degrading words ingrained into his mind. His lust-clouded eyes had long since forgotten concepts like dignity or pride.

[Good. How obedient.]

Kelles gripped Leonhardt’s waist and roughly thrust upward. The knight commander instantly let out a high-pitched cry and began to whimper. The more the monster looked at him, the more it wanted to torment that face. Leonhardt’s handsome, stoic features possessed a certain quality that provoked the most perverse desires.

[Does it feel good when I fuck you?]

“Nngh…! It-it feels good… So please, do it… harder…”

Leonhardt acted like a man incapable of satisfaction. The moment the shock of being rammed from the inside faded, he squeezed the hard demonic cock tightly, begging for more. Having briefly considered just toying with him, Kelles ruthlessly discarded its patience, flipping their positions to mount the human instead.

“Aahng…!”

That simple reversal drove the cock in so deep and hard that Leonhardt’s legs shook as he ejaculated. As expected, having the monster actively fuck him was infinitely more satisfying. Having admitted that fact, there was no longer any reason to resist; he was now slowly learning how to express his lust.

[If you love your husband’s cock that much, I have no choice but to feed you until you’re stuffed.]

“Ah…! Hah, ngh…! Haa, ah…! It’s so good, yes, Kel, huuuh…!”

Leonhardt floundered beneath Kelles as the monster drove into him with the ferocity of a rabid predator. Even so, he spread his legs wider to take the cock deeper, clinging tightly to the beast so he wouldn’t be shaken off.

[How dare you act so coy.]

Grinding out a low growl, Kelles battered Leonhardt’s insides as if trying to break him apart. Even now, the knight’s grip remained iron. There was nothing quite as entertaining as utterly ravaging such a physically robust body until it gave out beneath the force of copulation.

Opening its elongated, wolf-like snout to nip and bite all over Leonhardt’s body, Kelles exhaled hot breaths, moving with such violence that the veins on its forearms and thighs bulged.

[Haa… Hah, what a wicked little knight commander. Ah, wait, you aren’t a commander anymore. Congratulations once again on becoming my exclusive cum-dumpster.]

“Ngh, aah…! Ah, not there, my chest too… Ah…!”

Both of his nipples tingled sharply from the constant bouncing and impact. Thinking it would feel incredible to have his milk drawn right now, Leonhardt threw his arms around Kelles’s neck and rubbed his plump chest against the monster’s snout.

Letting out a beastly sound, Kelles ruthlessly ravished the thick nipples with its long tongue. With one hand, it milked the human’s breasts, while the other groped his lower belly, injecting demonic energy to heighten his arousal.

“Hic, nnngh…! Ah, right there, r-right there…!”

The instant the demonic energy brushed his womb, Leonhardt came again in thick, relentless streams, panting heavily. Perhaps it was because their hot breaths were mingling, but he felt even dizzier. His mind hazy, he wanted to feel the other’s scent and body heat just a little closer.

He had experienced sexual pleasure countless times by now, but this craving for the other’s sheer presence was a first. Unsure of how to resolve this newfound sensation, Leonhardt fumbled weakly at the monster’s snout, a needy moan escaping him.

He was thirsty. Even with his belly full of demonic energy, he felt strangely empty. Despite being violated every single day, he couldn’t fathom why he was suddenly feeling this way.

“Hah… Hah, hnnk… Haa…”

Kelles dragged its tongue in a long, sweeping motion from Leonhardt’s chest all the way to his jaw. It thought the breaths spilling from the human’s wet lips were far too ragged. The human’s feverish hands caressed the long snout, then seized it firmly, pulling it toward his own face.

“Mmph, hnnk… Ngh, aah…! Mmph…”

[Heh… There’s nothing you won’t do… even with a monster.]

Flinching for a split second at the strange sensation of their tongues touching, Leonhardt trembled but wrapped his arms tightly around the monster’s body. The elongated snout was hardly suited for sharing kisses, but he didn’t care. As the slick, thin tongue entwined with his own thick one, his mind grew increasingly hazy, and a bizarre sense of fulfillment bloomed within him—a feeling entirely different from the sheer satiety of absorbing demonic energy.

Melting into the warmth rather than the heat, Leonhardt finally realized that he wanted to soothe a deep, aching emptiness within him.

Ever since realizing he had been abandoned here, he had been lethargic, his heart feeling hollow as if a piece had been shattered. Unaware that what he was experiencing was profound loneliness, Leonhardt simply clung to the monster.

He thought he had already fallen to rock bottom, yet to his surprise, there was still further down to plummet.

Like it or not, this monster was now the only one who would listen to him and stay by his side. Because of that, he couldn’t bring himself to wholly hate or curse the beast. The creature had become an entity far too deeply entangled in his life.

“Haa… Haa… Mmph… Nnh…”

The dull ache in his chest felt as if it were subsiding just a little. Raw, fleshly pleasure and a desperate craving for connection tangled together, tightly ensnaring Leonhardt’s body.

The former knight commander acted just as his body and mind directed. Licking at the heat-slicked tongue, he had no choice but to desperately cling to the fulfillment of his most primal desires.

***

One cold day, Leonhardt clutched his belly with a pained groan. Beneath his heavily swollen stomach, the squirming movements of a new life fighting to be born were clearly visible.

What he carried was Kelles’s seed—or rather, a lifeform that could be better described as a clone. The mass of tentacles, practically an avatar of Kelles, had remained inside the human’s body for months, feeding on the generously injected demonic energy to grow rapidly. And now, it was just about to pry open the entrance of the womb and crawl out into the world.

“Ah…! Ah…! Aah, Kel…! Hnnk…!”

Sprawled across a bed of tentacle vines, Leonhardt squirmed, letting out cries that bordered on screams. Sitting beside him, preparing to receive the newborn, Kelles used its tentacles to pin the human’s limbs down so he couldn’t close his legs.

[It will be over soon. I purposely cultivated it to be just the right size for a human body.]

Knowing absolutely nothing about how to comfort someone, the monster eventually just placed a hand as large as a cauldron lid over Leonhardt’s belly. As it channeled demonic energy directly into the branded crest, the womb located just beneath it contracted sharply, evoking an overwhelming wave of intense arousal.

“Ngh…! Ah, hnnk, it-it feels weird…! It feels so good, aaaaah…!”

Leonhardt floundered in pleasure, panting as though he had run until his lungs were on the verge of bursting. Contracting violently, the womb secreted copious amounts of slick fluids, just as it did during climax, forcefully pushing out what it had been holding. The sensation of his tightly shut inner passage forcing itself open was spine-tingling; from the tip of his reflexively erect cock, fluids burst forth in thick streams.

“Aah…! Ah, huff, haah…”

Scraping against the wet inner walls, the squirming mass finally slipped out. Though lacking a conscious ego, the highly active newborn wriggled constantly, stretching open Leonhardt’s entrance—its father and surrogate mother—and poking its head out first.

“You’re doing well. It’s almost over.”

Having remained silent until now, Kelles only spoke once the newborn began to emerge. It was a small kindness, offered because it knew Leonhardt preferred to be addressed in human language. Of course, whether the human, completely swept away by intense sensations, even noticed that intent was highly doubtful.

“Haa… Haa… Hic…”

The newborn was little more than a massive lump. It possessed neither limbs nor eyes like a human. It barely had a distinguishable head and tail, and even then, it looked more like a sea anemone composed of numerous intertwined tentacles.

“Here… Come here…”

Feeling something touching between his legs, Leonhardt weakly reached out a hand. His heavily swollen belly had already deflated, and a dull, lingering thrill shuddered through him, leaving everything from his hole to his lower abdomen tingling.

“This way…”

Lacking eyes and ears, the only thing the creature possessed was a mouth for consuming nutrients. Wriggling over Leonhardt’s thigh, the newborn headed straight for his chest. It seemed to instinctively know exactly where the nutrient-rich juices were.

“That’s right… Good…”

It seemed the maternal instinct to love a child transcended species entirely. Treating the mass of tentacles with as much tender affection as if it were truly his own flesh and blood, Leonhardt turned his body so the newborn could suckle his milk.

[I didn’t expect you to look after the young so well. It seems I’ve acquired a much better wife than I anticipated.]

Since very few monster species actually cared for their young, Leonhardt’s actions seemed utterly foreign to Kelles. Nevertheless, the beast watched with deeply satisfied eyes as the human offered his breast.

Latching onto the chest dripping with milk, the baby tentacle opened its small mouth and bit down on the nipple. The sight of it eagerly suckling didn’t look all that different from any other animal nursing its young.

If there is anything you desire, speak. I am quite accustomed to using this body now; I can at least cast a recovery spell on you.

“…Kelles.”

[Why do you call me?]

A low growl rumbled in its chest as the monster posed the question. Watching him lie limply while having his milk drawn by the tentacles made it want to impregnate him all over again, but considering the human’s fragile emotional state, it restrained its jokes for once. With his free arm, Leonhardt reached out and weakly tapped the monster’s thigh.

“…You told me to say what I desired. Kelles, I want you.”

[You say the most amusing things.]

Slurp, suck.

The sound of the newborn drawing milk echoed through the cavern. Kelles narrowed its eyes, scrutinizing the exhausted human’s face. It highly doubted a stiff, former knight incapable of making jokes was simply pulling its leg.

“You said you wanted my body. You said you’d take my soul, too. And now… I have absolutely nothing left…”

Leonhardt’s face looked strangely hollow as he spoke. Part of it was the wave of depression rushing in after the explosive stimulation of childbirth had subsided, but another part was the sudden, jarring realization that their contract had ended.

He had sold his soul to save his knight order, but the physical contract ended here. Giving birth to its spawn. That was all Kelles had ever wanted.

Now that he had delivered the newborn, Kelles would raise the young creature into a sorcerer matching its own prowess, and before long, shatter its seal and step out into the world. He had heard nothing of its plans beyond that, but believing it wasn’t his place to interfere, he had never bothered to ask.

One thing was certain: he now had nowhere left to go. He vaguely recalled the monster mentioning dragging him down to hell someday, but it spouted nonsense so often that he wasn’t even sure if it had been serious.

“So I can’t accept this, if only out of pure spite. I have to claim something for myself, too.”

In his entire life, Knight Commander Leonhardt had never once laid his desires bare. As a knight commander, he had always been required to remain impartial; to practice an ascetic life, he could never show obsession or possessiveness over anything. However, Leonhardt the human was different. He knew how to feel anger, resentment, and ultimately, desperate craving. Having learned how to express his long-suppressed needs, he no longer held any reservations about baring his desires.

“Impregnate me again. I’ll birth as many of your young as you want, so don’t throw me out.”

Where could he possibly go with a body like this? In the end, he had to admit the beast had been right. It finally sank in that not only did he actively desire this grotesque monster, but he could no longer live without it.

It wasn’t simply because he had become a slave to physical pleasure. He had been reduced to a body that was neither fully human nor monster, and ultimately, this ancient beast was the only entity willing to desire him and remain by his side.

Staring down at the weakly mumbling human for a long while, Kelles didn’t answer. Instead, it positioned itself and mounted his body. It had already felt like its cock was going to explode just watching him nurse so demurely; with him practically begging to be impregnated, there was no reason to refuse.

[You should know, I am a creature of rather vast ambitions.]

Reaching out to grasp the human’s chin and turning his face this way and that, Kelles growled. Infusing him with demonic energy to soothe his body had clearly worked; Leonhardt’s complexion looked relatively healthy.

[If you say you want me, I am more than willing to give myself to you as much as you please. But you had best take full responsibility. That is simply how bargains with monsters work.]

A tentacle slithered up from the floor, coiling around Leonhardt’s neck like a snake and flicking its tongue against his cheek. Its tentacles loved to wrap around the human’s body. It was the monster’s own unique way of expressing affection, though sadly, the human had simply failed to grasp its true meaning.

However, knowing that the creature would not harm him, Leonhardt could completely surrender his weight to the appendages holding him. Kelles was undeniably a rough, cruel beast, but there were certainly times when it was far more trustworthy than any human. It was a truth he now had no choice but to accept.

The man who had plummeted from the heights of a knight commander to a monster’s mere possession turned his body to the side to accommodate the baby still suckling at his breast. Lifting one thigh, he whispered, “Hurry… put it in.”

As he raised his leg, the darkly tinted hole between his pale buttocks gaped wide, trailing long strings of clear fluid. Hooking one of Leonhardt’s legs over its shoulder and pulling out its pillar-like cock, Kelles made a silent vow.

True to its vast ambitions as a monster, it would absolutely ensure he became a knight commander once again.

***

A long time passed after that, and the people seemed to have forgotten all about the monsters that had emerged in the north. The coal mining village had fallen into decline, but other tourism industries had taken its place, and though it hadn’t regained its former glory, it had seemingly returned to a decent town bustling with people.

As the incident faded from everyone’s memory, the empty clearing where the sealing stone had been buried became overgrown with thick brambles, looking just like ruins. Although trees could not grow there due to the lingering demonic energy, a few highly resilient weeds stubbornly covered the ground. Perhaps they had spread their roots to greedily devour the nutrients born from the human blood and flesh that had been scattered across that very earth.

And then, late one night, a lone man stood in the clearing, untouched by human footsteps. Tall and sturdily built, he was a remarkably handsome man with pale skin and jet-black hair. Though the years hung from the corners of his face, his physique remained as taut and powerful as ever.

“Kelles,” Leonhardt whispered softly.

Standing beside him was a monster that resembled a massive beast.

I will begin, Father.

“Yes, go ahead and begin…”

A faint trace of a smile seemed to linger at the end of the voice scattering into the air. Leonhardt watched as his son, who had grown as tall as his father, dug up the soil where the sealing stone was buried and infused it with demonic energy.

Living alongside Kelles, he had learned that the monster was a far more masterful sorcerer than he had imagined. It had completely separated the newborn—which had been nothing more than a small cluster of tentacles—from itself, granting it a new ego. Furthermore, it had passed down its vast knowledge, ultimately enabling the spawn to unravel the complex seal.

Of course, their reproductive activities had continued unabated during all that time. Leonhardt had cared for his young with utmost devotion, and Kelles had endlessly provided him with pleasure to ensure the human never felt lonely.

[…I expected as much, but this is not easy.]

“Shh, there’s no need to rush. I waited until you grew this big; your father can certainly wait a few more years.”

[You’ve been waiting for today alone; I don’t wish to disappoint you.]

The firstborn possessed a much calmer temperament compared to Kelles. The monster had jokingly remarked that the boy seemed to have inherited his human father’s personality, and as he grew, he increasingly came to resemble Leonhardt, proving the jest to be entirely true.

Inheriting a monster’s magical power and stamina, along with a human’s diligence and steadfastness, the son had grown rapidly. As a result, after wrestling with the sealing stone while drenched in sweat, he had finally achieved the monumental feat of unraveling the first layer of the seal.

[Did you see? I’ve finally peeled off the first shell. It will be easy from here on out. The rest will be finished before dawn.]

“I’ll be waiting. You can always take a break if it gets too hard.”

Though his tone wasn’t quite as gentle as it used to be with the knights, Leonhardt answered in a voice that inspired deep trust. The son nodded and focused intently on his work once more. True to his word, right as dawn approached, the ground began to heave.

Crack, c-craaack!

A massive fissure split across the surface of the sealing stone, a loud sound echoing like shattering ice. Startled by the noise, the birds in the distance took flight with a flurry of flapping wings, and a light brighter than the sun engulfed the forest, creating a deeply ominous atmosphere.

“Kelles, Kelles…”

Moving forward carefully, step by step, like someone coming to greet an old lover, Leonhardt approached the light source. Within that blinding radiance, the burning black flames converged and scattered repeatedly, gradually taking on a distinct form.

Haaaa…

The sigh exhaled by the one who had slumbered for so long was deep and incredibly languid. The black flames soon coalesced into the shape of a massive giant, burning with endless vitality before a thunderous voice rumbled through the air.

[At last, I meet you in this body.]

A long, pitch-black finger swept across the human’s cheek. The flames, concentrated into a pointed tip, crackled as they touched his skin, sounding as if they were burning something, yet they carried no heat.

“Kelles…”

[Such sentimental nonsense. Instead of just calling my name, why don’t you try saying something else? Do I need to spout some cliché drivel? Some foolish remark about granting you a wish in return for freeing me from my seal.]

Instead of a low growl, a sound resembling a fierce gale now replaced its laughter. Reverting to the form Leonhardt was familiar with at the snap of a finger, Kelles leaned its wolf-like snout close to the human’s face and snickered.

[Or perhaps we should first enjoy a messy, unrestrained copulation to celebrate my regaining an intact physical body.]

“……”

Instead of responding to the joke, Leonhardt stood on his tiptoes, wrapping his arms tightly around the wolf’s neck in a firm embrace before letting go. Then, basking in the slowly brightening morning sun, he spoke.

“First, we’d best get out of here. As for the wish I’d like to make in celebration of you regaining your body… I’ll tell you when we reach our nest.”

[Acting all meaningful, are we? When I already know perfectly well what you’re going to wish for.]

Smirking, the corner of its mouth ticking upward, Kelles followed behind Leonhardt as the man turned to leave. Having quietly watched their reunion, the son casually asked, a hint of expectation coloring his tone.

[Father, did you not miss me?]

[I spoke with you perfectly fine yesterday, what is there to miss? The only one allowed to be sentimental is your father over there. Move quickly. We must grant your father’s deepest desire, mustn’t we?]

The only person Kelles ever treated gently was Leonhardt. Since monsters inherently lacked strong familial bonds, the son wasn’t particularly disappointed as he fell into step behind them.

Now, only the utterly destroyed sealing stone remained in the empty clearing.
