In the cool, misty air of early November, Eric ambled out into his backyard, the scene a chaotic scatter of wilting plants and shriveled pumpkin remains from the Halloween party that had swept through a few days ago. He sighed, knowing he should’ve cleaned it up sooner. As he bent down to lift a dried pumpkin vine, something caught his eye—a strange, shiny piece of candy lying nestled in the frost-kissed grass. As he knelt down to pick it up, a soft, sweet aroma wafted up, almost inviting him to taste it. Eric didn’t know why, but the candy seemed almost... alive? He chuckled at his own imagination and popped it into his mouth.

The flavor hit him like nothing he’d tasted before, a sweetness so intense it flooded his senses, warm and heavy. As he savored it, a shadow crept up behind him, silent as the fog that rolled over the garden. It pulsed, dark and oily, and before Eric could turn, the shadow rose up, forming into a sinuous figure that reached for him. In an instant, it pounced, its form turning liquid as it swallowed him from behind.

A thick, viscous substance engulfed him, cold and unyielding, spreading across his back and creeping around to his front. Eric struggled, but his movements slowed as the rubbery goo covered him inch by inch. Soon his body was entirely encased in a smooth, dark green latex-like substance that tightened and molded to every curve and crevice. He tried to scream, but his voice was trapped within, muffled and distorted.

And then, the transformation began.

A sharp sensation, somewhere between numbness and burning, took over his head. His mouth and nose elongated, twisting out into a snout, while tiny horns sprouted at his temples. He could feel his eyes changing shape, vision sharpening as his irises burned into an unsettling, vivid orange glow. His hands fused together into crude, three-fingered hooves, each emitting an unnatural glow. The goo thickened around his torso, covering him in a dark green rubber-like layer that seemed to grow with his form, conforming to his body like a second skin. A fine, dark coat appeared over his body, elegant and perfectly formal, as though he were some kind of nightmarish hotel receptionist.

When the transformation finally stopped, he looked down, horrified, and realized he was no longer entirely himself. His body was that of a hulking, beastly figure, covered in shiny rubber with the head of a cow and a long, sinuous tail that flicked behind him, ending in a glowing, trident-like tip that swayed in rhythm with the whispers rising in his mind. His bulge felt constrained, and when he glanced down, he saw a lock symbol marked across his groin, somehow part of the rubber casing—an emblem of chastity he could feel weighing on him with a strange permanence.

“You belong to us now,” a distant, eerie voice intoned. It echoed in his head, wiping away his own thoughts, sinking deep until he couldn’t remember why he had come outside at all. His mind faded, replaced by a strange obedience that pulsed with every word he heard.

A smirk crossed his rubber cow face as the whispering voice continued, giving him a purpose he couldn’t quite understand but felt compelled to obey. He raised one glowing, hoof-like hand and snapped it. In an instant, the ground beneath him darkened, swirling into a shadowy portal that stretched upwards, enveloping him just as the goo had done moments before. Slowly, the portal grew, pulling him down, engulfing his rubbery form inch by inch. The last thing he saw as he descended was his garden fading above him, the faint light swallowed by the dark, echoing world below.
