Artificial Instinct

Summary:

In the wake of her grief, Raiden Ei created a Puppet so lifelike, he could be mistaken for a human of flesh and bone. Only there was one major flaw: he had an unquenchable thirst to fuck.

Notes:

This originally was intended to be a Twitter fic, posted in short snippets. Which is why it is only 2k. But yeah, whatever. At least I wrote something!

Work Text:

She made him too human. 

The lovely, nameless puppet, meticulously designed by one with a heart steeled by grief, imitated the human race to perfection. But somehow, one particular trait was grossly exaggerated.

The innate urge to procreate.

At first, Ei thought she was doing right by indulging his curiosity. It was only fair that someone so new to the world learn all there is to know about the intricate body he would carry for the remainder of his immortal days. She kept the phrasing clinical, explaining the natural purpose of his genitals and how humans use them to plant the seed of life, a concept that a puppet created by the gentle hands of a God would have trouble grasping without proper clarification. 

But now, it was the fourth day. And the puppet refused to yield until he reached his impossibly human goal. 

To spill his divine seed within his creator. Fill her womb and create new life together. Birth a new God. 

Although well aware that this was a fruitless undertaking, a futile effort, Ei made no attempt to stop him. The ways in which he treated her body were blasphemous. Shameful and downright vile. 

But oh, Celestia above, was it exhilarating.

"Ngh!—That's it. Take my cock like the whore you are," The Puppet commanded.

"Such filth already from the mouth of a babe."

The Archon's head was wrenched back, their eyes meeting. The puppet quickly grew addicted to this move, fisting at her braid and yanking her back to face him. That delicate, otherworldly face she painstakingly molded looked unrecognizable to her in those moments. 

"I have you to thank for that, Beelzebul," he cooed sweetly. "You begged for it, filled my mind with every degrading word, and demanded them of me. If only the people of your precious Inazuma could see you now. A wanton mess, pleading with her creation for more."

Tenderness was lost by the second day. He pushed her head back down into the ground, holding her against the woven surface of the tatami. In those many hours of those few days, she'd allowed him to experiment with every position one could conjure.

Above all, he adored keeping his creator on her knees for him. 

The Archon never would have imagined that The Puppet's lust would be this unquenchable. The very first time he breached her cunt, it was as though a veil was lifted, changing him from the inside out. His innocence stripped in the flash of a lightning crack.

He was no longer her prototype for eternity, but her insatiable fuck machine. And while these last four passion drenched days kept her melancholy thoughts at bay, she knew that drowning her mind with pleasure was unsustainable.

But for now, she would allow herself to be lost to him, to take every rigid inch of the cock she handmade with exquisite detail and enjoy every last one of its reckless thrusts. 

"Beg for me, Ei. Beg for your perfect creation to fill your cunt again," he demanded, squeezing his fingertips into her mortal-like flesh, the same tender skin he so greedily snapped his hips against, endlessly. 

Her hands clawed for purchase against the mat, forearms red and tender with burns from friction. Ei's pussy squeezed around him in reply, a plea for more. More of him. More of this punishment she felt she deserved. 

"Yes! Breed me again and again. Don't stop until you're satisfied!" 

"Who would have ever imagined that the almighty God of Thunder would be such a cock hungry slut?" he teased, knowing damn well he would never be truly fulfilled.

 

···—–—⚜—–—···

 

An unsuppressable storm followed their every footstep to the gates of the domain. That night, a promise was made, a gift to be exchanged. It was intriguing enough to quell the Puppet's hunger long enough for Ei to dress him. Fine silks hung from his lithe frame, and a delicate veil crowned him, radiating the illusion of a fair maiden adorned in fragrant flora. 

Shakkei Pavilion was hardly the 'palace' Ei described it as, especially when compared to the imposing aura and commanding presence that was Tenshukakku. The Puppet took in his surroundings with a skeptical eye, but at this point, he bore little reason to doubt his creator. She gave him her word, to execute the purpose he had so adamantly tried to fulfill since the moment of his awakening. 

This place would serve as their Ōoku, the inner chambers where Shoguns met with their consort or concubines. Privacy was not something the Shogunate afforded in a place such as Inazuma City, so this ancient dwelling tucked into the mountainsides of Kannazuka would have to suffice. The Puppet's existence needed to remain a hushed obscurity.

While parts of the mansion appeared dilapidated, unkempt, and lost to time, with crates stacked high and broken screens long overdue for repair, the Puppet became awestruck when Ei led him to a grand room. One more fitting of the elegance he expected to find inside the domain. Two maple trees and two Odaiko drums branded with the symbol of their nation stood opposite each other. In the center, a gargantuan door loomed like a giant in the dark, carved with the silhouettes of two identical figures.

Baal and Beelzebul. Makoto and Ei. 

The Puppet was vaguely aware of the extent of her grief. He only knew the loss of Makoto was the sole reason for his existence. Being in this place, surrounded by reminders of everything Ei once held dear, only seemed to fuel his desires. He would serve a greater purpose than his predecessor. 

His conception of Inazuma's eternity would become the final iteration.

Now, he took the lead. There was an unexpected softness in the way he took Ei by the hand and led her towards the east-facing maple. The ground was littered with its fallen leaves, still as vibrantly amber as they were the day they fell, possibly centuries prior. This domain lay frozen, a manifestation of Ei's eternity. Stillness. Unchanging. 

They stood over the leaves, facing one another. Silently, the Puppet began to undress her, in a way that felt like a duty, an obligation. In the recesses of his mind, he longed for them to be equals, to stand beside her as the new Archon of Inazuma, but it was all a foolery. He was well aware of his current place, but once she conceived his heir, then and only then could they stand shoulder to shoulder.

Her kimono pooled at her feet, and the Puppet knelt to its knees, stripping each stocking down her thighs, and taking the time to gently lift her feet and place the hosiery to the side. His lips fluttered light kisses to the supple skin, making a slow path upward toward her sex. As he reached her inner thigh, he inhaled. The scent of her was a heavenly perfume, ripe and sweet, and he could feel that lust he was trying so desperately to subdue begin to surface. 

He stood fully again and made haste with his own undressing. Ei simply stared, quiet and contemplative. She found little point in resisting him. This was her gift to him, as she said—the beginnings of his grand plan for eternity. She would let him have his way.

One final time. 

In the moment before he laid her down in the bed of leaves, she couldn't help but admire what she had brought into the world. Even if he did not turn out to be useful for his intended purpose, he was still a marvel, a beauty. What a terrible shame that this would be the last time she would ever lay her eyes upon him. 

He was still moving at a curiously gentle pace, crawling up her body and examining every inch of her like a lustrous prize. She could see the suppressed hunger behind his gaze, the urge to tear her apart being held back for a greater purpose. He was lost in thoughts of the future, taking in her every feature as he imagined what their offspring would look like. 

A light brushing of his hair tickled her chest as it hung over his face, dipping down to catch her nipple in his warm, wet mouth. Her breath hitched as he slowly suckled her, tracing the curve of her breast with his fingertips, imagining them heavy with milk for their firstborn. The thought sent electric pulses through his cock, pressing insistently against Ei's cunt. 

A blush came to her cheeks at the feeling. Even after all the times she had let him fuck her, she still felt awashed with shame over how her body responded to his ravaging. Someone like her, a prideful woman of conviction, should not be soaking wet as the young man she had brought to life lapped at her nipples and guided his aching erection towards her slit. But she could not deny or ignore her own lust, her own selfish desires. 

Unlatching from her nipple with a soft pop, he ran the tip of his cock up and down her slit, slicking himself with her fragrant juices. 

"There's no need to be so embarrassed, Beelzebul. I know you've been loving every minute of our time together, and no one but us needs to know…" he said with a trail of soft laughter. His hand came to caress her cheek, a soothing gesture for what was to come. 

Her shoulders tensed, breath stolen as he rammed his cock inside in one swift thrust. Stilling for a moment, he leaned down to her ear and whispered, "At least, not until they all notice your protruding belly, filled with our growing child…"

She was not about to shatter his disillusions, not when he was slamming inside her with fervent intent. Exposing the truth now would only fill him with an emotion he had yet to feel: heartbreak. He would never be able to fulfill his human desires, she knew this all along. No matter how lifelike and human appearing he had been made, he was still merely a Puppet; one incapable of reproducing. He would never create an heir, or anything else for that matter. 

All Ei could do was moan, writhe beneath him, and play along. 

"Please… I want it. I need the real thing. Please, make a real mother of me," she begged and whimpered. 

The Puppet's hands pressed hard against her shoulders, pinning her down as he pistoned his hips against her, feeling that primal human heat building beneath the surface. His face was a mere shadow of lust as he hovered over her in the faint light of the room, determined to fill her over and over for as long as necessary. 

"You're my shadow now, Ei. You're going to love my vision for eternity. One where I keep you as my full and pregnant sow until your body turns to dust."

She could see his face begin to contort, the telltale signs that he was about to spill inside, his mouth hanging open as he panted and grunted. That's when she made her move. 

Two fingers pressed against the soft palate, and The Puppet let out a choking gurgle, eyes widening as Ei began to count. 

"Three… Two… One…"

Before he could even begin to panic, his body fell limp, collapsing on top of Ei as she let out a weary sigh. Slowly closing her eyes, she pulled his already softened cock from inside her, his seed spilling out from her cunt as she did.

Gently, she rolled him over onto his side. With the soft touch of her fingertips, she slid his eyelids closed. Her hand stayed cupped to his cheek for only a moment, but Ei did not shed tears for her failed creation. For in her eyes, she had lifted him from his burdens, sheltered him from a dream he could never realize.

"You're too innocent to live this lie. Now, you will sleep… for all eternity."

Unknowingly, she only shackled him to a life of aimless wandering, to freedom. That night, Ei walked away from her prototype, prepared to try again. This time, she would execute it flawlessly. 

 

This time, she would make it past the fifth night and give her creation a name.
