The Ebony Maw - Yveltal Vore

A moderately long line piled up at one of the sidewalks in Lumiose City, snaking to the front entrance of one of the grander theatres of the entire region.

The Ebon Maw, one of Lumiose's most enigmatic attractions, was home to the esteemed Dark magician Yveltal. Many Pokémon visited, yet few ever spoke of their experiences. The occasional disappearances were never questioned—such was the nature of Yveltal’s domain.

At the stroke of eight, the doors creaked open, welcoming the eager audience into a lavish, dimly lit hall draped in deep crimson. Golden chandeliers flickered overhead, casting an eerie glow as guests made their way toward the auditorium, where round tables cloaked in rich velvet awaited them.

Excitement crackled in the air as Pokémon of all shapes and sizes settled in, their hushed murmurs carrying through the room. Even a Gyarados, somehow crammed into the back, added to the growing anticipation. Then, the lights dimmed. Silence fell as the curtains parted, revealing a polished black marble stage. A single spotlight flared to life, illuminating the enigmatic host. With the flourish of a deep red cloak and a knowing sharp-eyed grin, Yveltal stepped forward.

"Welcome, one and all, to a night of mystery, wonder, and unparalleled spectacle!"

The crowd erupted into applause as Yveltal stood tall, wings outstretched in theatrical grandeur. He let the excitement simmer before continuing, his voice smooth yet commanding.

"Prepare yourselves, dear guests, for an evening unlike any other—a performance that will linger in your minds long after the final curtain falls."

With a graceful sweep of his wing, the spotlight shifted, revealing the night’s first participants: a Blaziken, a Galvantula, and a burly Tyranitar. Yveltal stepped forth, his gaze glinting with mischief, draping a wing over them like a shadowy cloak.

"One… two… and—voilà!"

In an instant, his wing retreated, revealing that the trio had vanished—only to reappear within the taut curve of his waistcoat-clad belly. His stomach gurgled ominously as the trapped Pokémon struggled, their muffled protests drowned by thunderous applause. The crowd was ecstatic, entranced by the impossible feat.

"And now, my esteemed guests… I require more daring volunteers!"

A gleam of hunger flashed in Yveltal’s eyes as more eager Pokémon stepped onto the stage. Without hesitation, he coiled his tail around a Boldore, a Metang, a Sawsbuck, a Swellow, and a Buneary, yanking them toward his waiting maw.

"Mmm, a fine selection..."

He purred, voice reverberating through the hall.

"Let us see how they fare in my... inner sanctum."

His beak yawned open, revealing an abyssal darkness within. The Pokémon yelped as they tumbled inside, vanishing in a wet gulp. His belly stretched further, the waistcoat straining against the swelling mass, yet he wasted no time reaching for more.

"Ahh, a delicacy from Kalos!"

He hoisted a plump Farfetch’d high before swallowing him whole, savoring the squirming sensation as his gut distended once more. The audience cheered wildly, enthralled by the spectacle. More and more the Yveltal gorged on his ready and willing participants, his belly outstretching further and further. His gut spilled out of his coat, the velvet-red and black texture growing more taut with each prey Yveltal gulped whole.

"GLURK! GULP~"

Yveltal's feast continued as the night passed. Swallowing a particularly large Gyarados, he had to grip his burgeoning belly for support with his claws as it spilled out even further. With each wet gulp he took, his excited expression intensified, those blue eyes glistening with glee as they took notice of a large Lugia heading down his maw.

"GULP.... gurgle..."

Yveltal was forced to step down to the floor, his oversized gut blowing even further, gurgling and churning with roughly 50 Pokemon crammed inside. The avian Pokemon's limbs were too preoccupied to help with his feast any longer, forcing him to rely on the assistance of his guards, who slipped one prey after another as he readily gulped and swallowed until his gut was larger than a yoga ball.

As the night reached its climax, Yveltal’s gaze locked onto a massive Rayquaza, writhing in his iron grip. The packed theatre held its breath, caught between horror and awe.

"This magnificent beast shall be tonight’s grand finale!"

With a thunderous slam, Yveltal drove the Rayquaza into the stage, knocking the wind from its lungs. Wrapping his arms around the serpent-like dragon, he hoisted it effortlessly, his eyes glinting with unrestrained hunger.

With a deep, monstrous inhale, he stretched his maw impossibly wide. The Rayquaza slid down his throat in a sickening, wet gulp that seemed to last an eternity.

"GLUUUURRRRPPPPPTTTT!!!"

The theatre trembled as Yveltal’s belly ballooned outward, stretching far beyond its limits. His waistcoat strained against the immense girth, the sheer weight of his feast making the entire venue quake. Then, with a shuddering breath, he clenched his jaw, summoning his unholy draconic power.

A deafening crack split the air as his grotesquely bloated gut began to shrink, his body greedily devouring the raw energy within. The remaining Pokémon within his belly squirmed, their struggles fading as the auditorium groaned under the strain.

With a final, bone-shattering crunch, Yveltal stood tall, his stomach now taut and firm once more, a lithe smooth surface covered in feathers. He spread his wings wide, striking a triumphant flex beneath the flickering lights.

"And with that… I suppose that's enough excitement for one night! Any other requests for the time being?"
