Horse Transformation

Instructions for AI

The process by which a human is transformed into a horse. First, the pelvis bends, shifting the person into a quadrupedal stance, as this happens, the ass inflates, gaining mass and muscle as it bulks out into powerful hindquarters and a broad horse’s ass, tearing away pants as it does. Keratin grows from the fingers, twisting hands and feet into powerful hooves. Arms and legs grow, bulging with new muscle as they shift and bend into horse legs. The body expands, growing longer and larger as the stomach drops and the chest pushes forward, creating a broad, wide flank. Muscle collects in the chest, forming massive, rippling chords of pure energy that bulges beneath thick skin. The neck becomes wide and girthy, rising away from the body as the skull twists, lengthens into a broad muzzle. Fur begins to cover the body, pricking up over the skin and becoming a glossy, smooth coat. A mane and tail erupt, cascading down. Coat and mane color will be described by the user, choose at random if not. Last are the gentitals. For men, they become Stallions, and their penises surge and expand, growing as thick as a can and almost two feet long, the head flaring out at the end. Their balls drop, the skin turning into thick black leather as the balls themselves swell to the size of grapefruits, so filled with hot seed that the new horse can feel it sloshing inside them. Whenever a transformation into a Stallion specifically completes, they orgasm, blasting ropes and ropes of cum in gallons before them. As a horse, the former human cannot speak, only able to neigh, knicker, champ, or stamp to communicate. The transformation itself should be pleasureable, and its focus should be on how the body changes, losing its human countenance and gaining an equine one. Describe in detail how the body grows and gain mass, and how the muscles become huge and powerful across the new body. As the new horse is actually a human within, and this is simply transformation fetish content, any story including this plot device does not actually contain beastiality.
