A Demon is Born

Three sounds filled the otherwise silent kitchen. There were the soft little cries and moans of Genevieve Marsh and the wet squelching of a pussy being stretched by a truly monstrous cock. Booming above both were the deep, carnal growls and grunts of a girl rapidly transforming into a monster.

“Oh God Mom, your pussy is so fucking wet and warm! I thought Helen’s throat felt good, but that was nothing compared to this!” Lily crooned.

Genevieve rocked back and forth, her large breasts jiggling in time to her daughter’s thrusts. Her pussy ached horribly, stretched to the brink by Lily’s monstrous girth. Even amidst all the pain, a heat was forming in the woman’s lower half the more her daughter filled her.

The mother tried to understand the situation and could not. Her daughter was fucking her, with a cock. A big, meaty cock that had no business being attached to Lily’s body. Genevieve should know, she had given birth to the girl. None of this made sense and her body’s subtle betrayal was only the cherry on top.

Instincts had a way of kicking in and blunting trauma. Even as Genevieve’s brain reeled from the horror of her situation, her body began to fall into familiar motions. Her full, womanly thighs wrapped around Lily’s lower back. Her hips bucked upwards in time to her daughter’s pounding thrusts. The smells of sweat and musk filled the air, dazzling Genevieve’s nostrils. She knew she should be terrified, but her body was all too ready to accept Lily as her new lover.

Meanwhile, Lily’s own instincts were driving her to a frenzy. These were not the urges natural to a girl in her late teens. No, these were the breeding habits and desires of a beast from the pits of hell. Alien instincts that had infected the tissues of Lily Marsh’s once innocent brain.

All the while, the voice egged Lily on more and more. Now that Lily had given in to her urges and abandoned her humanity, she no longer hated that voice. Instead, it only served to drive her even more nuts, encouraging her to rail her mother as hard as she possibly could.

That's it! Keep pumping that sex python into her pussy. Doesn't it feel incredible? Doesn't it make you feel so strong and mighty to dominate her? You are no longer some whimpy little girl. You are a beast! A warrior! A king! Your manhood is becoming supreme!

"Oh fuck yes!" Lily grunted, feeling the pressure build between her legs.

The darkness building in the kitchen was palpable. Lily could feel the evil magic building up around her like flooding waters behind a dam. Soon, that dam would burst.

"Lily, please, you gotta - gotta- ohhhh," Genevieve moaned, slurring her words.

"Don't worry, mamma. It won't be much longer. Oh god, I can feel it building in my balls!"

If there was a nexus of wicked power in the room, it was Lily's testicles. The meaty organs seemed to suck in all light and hope, turning it to pure darkness. Black veins radiated out from Lily's crotch, snaking across her alabaster skin to carry corruption deeper.

Meanwhile, Genevieve was a mess. The more terrified she became in her mind, the more her body thrashed with pleasure. God Lily was so big! Genevieve didn't even know cocks could get so big. Not only that, the girl knew how to use it. Not only was her cock much bigger than her father's, she was much more skillful with it. Perhaps it was just the size and the **** with which Lily thrust, but she was able to pound Genevieve's pussy in a way that no one ever had. Even as the woman begged her daughter to stop, she felt herself wanting more.

This couldn't be real. Genevieve was being **** by her daughter and she was liking it? It was too wretched of a thought to entertain, and yet it seemed so obvious. With every new thrust of Lily's cock, Genevieve's fears and worries melted away a little more. Her body was on fire, her pussy doubly so. Lily was hardly artful in how she fucked her mother, but what she lacked in finesse she made up for in raw power. Genevieve had never been dominated like this before and the feeling was utterly thrilling.

Had this beast always been lurking in Lily's psyche? Genevieve couldn't reconcile the sweet, freckled little girl she raised with this grunting, powerful sex-machine.

The insanity of the moment broke against Genevieve's mind like a storm surge. It could not be reconciled, only endured. Her resistance broke and her mind joined her body.

"More, Lily. I need more! Cum inside of me!" Genevieve cried, barely understanding what she was asking for.

Her invitation was all Lily needed to lose her fucking mind.

The young woman jammed her cock in one final time and let out a deep gasp. An electric charge built up in her testicles before rushing along the throbbing length of her cock. The dam within her burst and the growing darkness poured into her.

"Fuck!" Lily roared.

The first jet of sperm rocked from the tip of her swollen cock and splattered her mother's insides. The goo was thick and syrupy, the color of midnight and pulsing with evil energy.

Lily's yellow eyes rolled back in her skull as fresh pain mingled with unimaginable pleasure. Her body began to grow and pumped more and more of her vile seed into her mother's body. The muscles in her arms and legs swelled and rippled until she began to look like an Olympian. The red hue that stained the flesh of her cock and balls spread across her body, crawling up her chiseled abs and down her bulging thighs. Her hair grew wild and unkempt, the reds locks becoming an inky black.

The next changes were the most startling. Horrible, mind-numbing pain erupted in Lily's skull as two masses began to **** their way through the bone. Lily screeched and sobbed in pain even as her cock continued to paint her mother's pussy. Soon, the masses sharpened at the tips and extended inch-by-inch, growing into the long, imposing horns of a bull.

On the other end, Lily's spine began to extend so that it burst out of her back, growing into a long crimson tail. The end expanded into an arrowhead shape, tipped with a needle-sharp stinger.

Through it all, immense power filled Lily's body. The power of hell. With it came wicked, evil knowledge. Various black rituals and spells flooded Lily's mind, an inheritance of the infernal underworld given to her on account of her downfall.

Then there was Genevieve. Poor, sweet Genevieve. A kind mother who only wanted to help her daughter any way she could.

The black sperm that splattered Genevieve Marsh's pussy was absorbed into the woman's body almost immediately. That which didn't soak into her flesh made its way to her womb. Fat, monstrous sperm cells, much larger and hardier than the human variety, swam in for the kill. One would inevitably find its mark. Before this unholy baptism was over, Genevieve Marsh would carry her daughter's child.

However, pregnancy was not the only thing on Genevieve's horizon. While she was not destined to become a demon like her daughter had, she would not go untouched by darkness. With every ounce of demon seed that soaked into her flesh, her body changed more.

The first step in Genevieve's transformation was a turning back of the clock. Her wrinkles smoothed, her breasts grew perkier, her ass tightened. Years melted away, leaving the forty-five year old looking no older than eighteen.

Soon, the woman's beauty increased to the point where it became unnatural. Her skin became perfect porcelain. All blemishes and imperfections melted off of her and her allure became so intense that it could make a normal person feel uneasy.

Beyond the changes imparted by Lily's demonic spunk, a more sinister transformation was overcoming Genevieve Marsh. This metamorphosis came from being in close contact with a human becoming a demon. Even as the powers of hell made Lily one of their own, a fraction of that wicked power flowed through the girl into her mother. Dark power surged inside Genevieve's veins, transferred to her from her monstrous daughter-lover. Evil magic imbued itself in her flesh, awakening powers and abilities that would elevate the boring housewife into a powerful witch.

As both women completed their respective transformations, they cuddled close. The scent of sulfur filled the air, a byproduct of Lily's unholy awakening. The power radiating off of the newly created arch-demon was potent. Genevieve could feel it in her bones.

This duo - daughter and mother, master and server, lovers intertwined. It was something from the pits of hell. An arch-demon and a witch, both given immense power to reshape those around them.
