[Story] A Girl Transforms into a Fat Horse (Patreon)

The barn was dim, the air thick with the scent of hay and damp wood. She stumbled inside, clutching her stomach, her twin braids swinging wildly as she gasped for breath. Something was wrong—terribly wrong. Her skin prickled, a strange heat spreading through her body like wildfire. She leaned against a wooden beam, her breath coming in ragged bursts, and looked down at her hands. They were trembling, the fingers twitching unnaturally, as if they no longer belonged to her.

Her jeans, once snug, began to strain against her thighs. She groaned, a deep, guttural sound that startled her. Her body was swelling, her hips widening, her stomach rounding out as if she were being inflated from within. The denim tore with a sickening rip as her backside expanded, the fabric unable to contain the sudden growth. Her braids clung to her sweat-slicked neck as she doubled over, her breath hitching in her throat.

Her face was next. She reached up, her fingers brushing against her nose, and felt it—hardening, elongating. Her nostrils flared, widening into wet caverns as her nose stretched forward, the cartilage reshaping itself with audible cracks. She screamed, but the sound was distorted, guttural, more like a whinny than a human cry. Her lips pulled back, revealing teeth that were shifting, growing larger, flatter. Her tongue felt thick and heavy in her mouth, her jaw aching as it jutted forward.

Her hands were next. She stared in horror as her fingers began to fuse together, the skin between them stretching and darkening. Bones cracked and reshaped themselves, her palms thickening, her nails hardening into glossy black hooves. She tried to flex her fingers, but they were gone, replaced by something alien and ungainly. Her arms trembled as they grew longer, the muscles bulging beneath her skin, which was now sprouting coarse, reddish hair.

Her feet followed suit, her boots splitting apart as her toes fused and her arches lifted, the transformation mirroring what had happened to her hands. She staggered, her new hooves clacking against the wooden floor, her balance shifting as her legs bent backward, the joints realigning with sickening pops. Her spine lengthened, her torso expanding, her ribs cracking as they reformed to accommodate her new, massive frame.

She collapsed onto all fours, her body convulsing as the transformation reached its peak. Her ragged clothes were barely clinging on, draped over her fat body. Her braids unraveled, the hair merging with the coarse mane that sprouted along her neck. Her makeup—smudged and running—streaked down her face, the black mascara contrasting with the whites of her scared eyes.

When it was over, she lay there, panting, her big chest rising and falling with each labored breath. She tried to speak, to scream, but all that came out was a low, mournful whinny. The barn was silent except for the sound of her hooves scraping against the floor as she struggled to stand, her new body unfamiliar and unwieldy.
