Darlala had always been a very demanding demon, and her latest craving was for a human slave to attend to her every need. Her ass was a glorious monument to the seven deadly sins, and she knew that no mortal man could resist its allure. So, she set out into the world of humans, her eyes peeled for the perfect specimen.

It didn't take long before she stumbled upon a young, handsome man named Tomas. He was a simple peasant, working the fields under the sweltering sun, his muscles bulging with every swing of the scythe. Darlala knew that Tomas would be perfect, and she began to weave her seductive magic around him.

Tom's eyes grew wide as he felt a strange warmth spread through his body. His cock grew hard in his pants, and he couldn't help but stare at Darlala's massive, jiggling ass as it beckoned to him. She had the power to make any man lust for her, and she used it to full effect.

"Tomas, my dear," she purred in a voice that seemed to melt the very air around them. "I need someone to help me with my... needs."

Tomas was entranced. He could feel his will slipping away, his only desire to serve the demon goddess before him. He stumbled after her as she led him to her lair, deep in the bowels of the earth.

Once they arrived, Darlala wasted no time. She ordered Tomas to strip, and he obeyed without a second thought. The sight of his cock, standing at full attention, made her even hungrier for his worship.

"Lick my ass, Tomas," she ordered, turning around and presenting her monumental posterior. "Clean and pleasure me until I am content."

Tomas didn't need any further encouragement. He fell to his knees and began to worship Darlala's fleshy crack with his tongue. She moaned with pleasure as he eagerly lapped at her, his tongue delving deep to taste her dark, forbidden hole.

Days turned into weeks, and Tomas's life became a blur of feeding Darlala and servicing her insatiable ass. She consumed copious amounts of food, her mouth and throat stretching to accommodate her gluttonous needs. His tongue grew stronger from the constant cleaning of her anus, and his cock, never allowed to go flaccid, remained hard as he fucked her endlessly.

Darlala reveled in her new plaything. With a wave of her hand, she could make him cum again and again, his seed spurting forth like a fountain. She grew fatter and more voluptuous with every orgasm she took from him, her ass ballooning to unprecedented sizes.

Tomas's days were consumed by his mad obsession for Darlala. Every waking moment was dedicated to her, to her pleasure, to her immense ass. Her seductive powers had transformed him into a creature of pure, unbridled lust.

Darlala would sit upon her throne, a mountain of flesh and sin, as Tomas tirelessly ate and fucked her. He couldn't get enough of her, his face perpetually buried between her thick, quivering ass cheeks. Her stench was intoxicating, and he lapped at her sticky folds as if he were a starving man at a feast.

Her moans of pleasure echoed through the cavernous chamber as Tomas' tongue danced across her anus. She grew fatter and more powerful with every bite of food he forced down her throat. Her ass swelled to a size that defied logic, yet Tomas found it only grew more alluring.

When Darlala wasn't being fed, she would demand that Tomas fuck her. She had him in every conceivable position, his cock sliding in and out of her like a hot knife through butter. Despite his exhaustion, Tomas found that he could not get enough of her. The greed for her body overwhelmed any sense of self-preservation he might have had.

But even as he served her, a small part of Tomas' mind rebelled. He knew that this couldn't go on forever, that he would be destroyed by his own desires. Yet, he was powerless to resist her. Her eyes, burning with lust and hunger, held him in her thrall.

One day, as Tomas lay panting on the ground, his body covered in a sheen of sweat and cum, Darlala decided to up the ante. "You shall feast upon my ass until you can no longer move," she declared, her voice like a siren's song.

Tomas obeyed without question, his tongue slithering across her flesh like a serpent. He could feel her growing larger, more dominant with every stroke. Her ass was a black hole of lust that threatened to consume him entirely.

Days passed, and Tomas was lost in his frenzied worship. He was no longer the man he once was; he had become a mindless servant to Darlala's every whim. His tongue grew calloused and raw, his jaw ached from the constant motion, but still he licked and fucked without ceasing.

As her ass grew larger, so too did her hunger for more. Tomas was pushed to his breaking point, his body on the verge of collapse. Yet he continued, driven by a need that was no longer his own.

The demon's power over him was absolute, and she reveled in it. Her ass was a throne of pleasure that he could never hope to conquer, no matter how hard he tried. And so, Tomas remained, trapped in an endless cycle of feeding and fucking, his humanity slipping away with every passing moment.

As Tomas' sanity began to unravel, Darlala's smile grew wider. She knew that she had truly claimed him, body and soul. His obsession was complete, and she decided it was time to seal the deal.

"Tomas," she cooed, her voice a velvet caress on his fevered mind. "You have served me well. But now, you shall serve me forever."

With a flick of her wrist, she bestowed upon him the gift of immortality. Tomas' eyes widened in horror as he realized the true extent of his fate. He was to be her eternal servant, bound to her by an insatiable lust that would never die.

As the power seeped into him, Tomas felt his body change. His muscles grew harder and more defined, his cock thickened and elongated, and his tongue grew prehensile, capable of reaching deeper into her cavernous ass than ever before. He was now the ultimate ass-slave, a creature of pure, unending desire.

Darlala grew even more massive, her ass a towering peak that Tomas could never hope to conquer. Yet, he knew he had no choice but to continue his servitude. The thought of eternity spent worshipping her ass was both terrifying and exhilarating.

For centuries, Tomas served Darlala, feeding her, fucking her, and cleaning her without end. He watched as civilizations rose and fell above them, as the earth itself changed and evolved. And all the while, he remained trapped in the throes of his own desires, a living embodiment of the seven deadly sins.

Darlala's ass grew so large that it filled the chamber, the very walls of the lair bending to accommodate its girth. Her moans of pleasure could be heard for miles around, a constant reminder of the power she held over him.

Yet, amidst the madness, Tomas found a strange solace in his servitude. His world had become a simple cycle of feeding and fucking, and in that simplicity, there was a perverse kind of peace. He was a creature of pure instinct, and as long as he served his mistress, his needs were met.

As the millennia passed, Tomas' legend grew. Stories of the immortal ass-slave who could not escape the demon queen's grip spread like wildfire among the humans who dared to venture near Darlala's domain. Some sought him out, hoping to find a way to end his torment. Others came to offer themselves up, hoping to share in his eternal pleasure.

But Tomas was beyond saving, or so it seemed. He had become one with Darlala's ass, his existence defined by her every whim. And so, he remained, a captive in the dungeon of lust, forever serving his demonic mistress.

Darlala grew even fatter, her ass swelling to proportions that defied the very fabric of reality. And Tomas, ever-faithful, continued to eat and fuck and clean, his tongue never tiring, his cock never softening.

In the end, it was not death that claimed Tomas, but rather the slow march of time and the inevitable decay of his sanity. As the ages passed, his mind fractured into a thousand pieces, each one consumed by the unquenchable fire of his lust.

Yet, even as he lost his sense of self, his body remained strong, his need for Darlala's ass an eternal flame that burned within him. He became a creature of myth and legend, the ultimate symbol of carnality and debauchery.

And so, the story of Darlala and her immortal ass-slave Tomas passed into the annals of time, a cautionary tale of desire run amok and the dangers of serving the seven deadly sins. But deep in the bowels of the earth, their twisted love affair continued unabated, a testament to the enduring power of the flesh.
