Elixir of Ember

Barquas sat hunched over the heavy oak table in his basement lab. The stone walls were cold, the air thick with the smell of burnt herbs and old sweat. For weeks now, he had been working on a potion he dubbed the Elixir of Ember meant to enhance physical strength and lust, a hybrid of aphrodisiac and transformation catalyst. Marginal notes in his alchemical codex warned of unstable outcomes, but Barquas was already burning with arousal at the thought.

He lifted the vial a thick, reddish gold liquid with the texture of semen. He stared at it for a moment, then drank it in one go.

The potion was hot. It slid down his throat like molten honey, igniting his core with unnatural heat. Within seconds, the fire gathered in his loins not a tingling, but a brutal surge that bent him over the table, groaning as his hands clawed at the wood.

His cock swelled instantly engorged, throbbing with the rhythm of his racing heart. Skin stretched. Blood surged. He gritted his teeth as it grew beyond what his body had ever handled.

"What the fuck..." he gasped, but it was already too late.

The first jet of cum burst out of him with feral force. Thick, hot, and endless, it sprayed over his notes, the floor, and himself. His body convulsed, the orgasm tearing through him like a beast. Again. And again. He dropped to his knees, groaning through the wave after wave of involuntary release.

That’s when the true change began.

His fingers thickened, nails blackening into claws. His skin itched then bristled with a cascade of coarse, silver-gray fur. A mane exploded from the back of his head and down his spine. His face stretched, twisted, reformed into a lion’s muzzle, though aged the face of a grizzled predator.

His harness groaned around his growing torso. Straps bit into new muscle, but miraculously held, now framing a beastly chest. His thighs expanded. His feet cracked and reshaped into feline paws, claws grinding into the stone floor.

Between his legs, the transformation was equally extreme. His cock had become leonine, veined and barbed, sheened in slick fluid. It throbbed violently, still leaking from the climax that hadn't truly stopped.

He growled deep, resonant, and full of primal hunger.

"What... am I..." he rasped, standing shakily. The mirror on the wall caught his eye. He turned and stared.

A lion. Silver-furred, hulking, brutal. Harness intact. Dripping.

He licked his muzzle slowly. Arousal flared again stronger now, instinctual, raw. His tail flicked as he stepped closer to the mirror. He looked at his new form muscles tight under fur, cock swinging with impossible weight and let out a low, pleased rumble.

"This is me."

He dragged a clawed hand down his belly, past the beltline of the harness, until it wrapped around the slick base of his transformed length. His hips twitched. He exhaled, steam rising from his nose.

"The Elixir works."

Barquas was no longer a man of study. He was a beast of desire.

And now... he needed a test subject.
