She explores her new self

Carefully navigating her way back through the ceiling opening, Amelia lowered her four human feet onto the main floor. After exiting the attic, she looked down at the empty wheelchair sitting in the hallway—the device that had been her prison for months. Feeling a strange rush of liberation, she pushed the wheelchair aside.

As she traveled down the corridor, her movements became smoother. Her brain was rapidly adapting to the quadrupedal gait, her front and back pairs of legs moving in a seamless, synchronized rhythm that felt increasingly natural.

She turned into the modern bathroom and stepped into the large walk-in shower. Taking a warm bath was a challenge; she barely fit into the space with her elongated, quadrupled body, requiring her to maneuver carefully to get every part of herself under the soothing stream of water.

Once she finished rinsing off the ash and attic dust, she stepped out onto the bathmat. The bathroom featured a giant, floor-to-ceiling mirror, and Amelia stepped in front of it to explore her new anatomy even further.

Her black, glossy hair was now clean, framing a face that looked flushed and alive. Looking down, she noticed the transformation hadn't just affected her lower half. Her breasts had grown drastically, ballooning from an A-cup into a full F-cup. Staring at her exposed nipples in the mirror, she reached out and squeezed them a bit, marveling at the intense sensitivity and the sheer fullness of her altered upper chest.

She took a step back to view the whole picture. Her upper body was now incredibly fit and healthy instead of skinny and weak from months of muscle atrophy. The exact same thing had happened to her lower half; it was muscular, fit, and healthy as well, defined by four powerful human legs and feet. The secondary vertical torso gave her the unmistakable silhouette of a horse, but completely devoid of fur, leaving her entire form covered in smooth, flawless skin. With the structural shift, her genitals were now located at the back hips instead of the front.

And, of course, there was her tail.

Turning her upper body to look over her shoulder, she stared at the long, elegant tail that possessed the exact same deep black color as her hair. Intrigued, she experimented with the new muscles at the base of her spine. She wiggled it a bit, then waved it back and forth through the air, watching it swish gracefully.

The movement brought a small, unexpected smile to her lips. She realized that not every change was as bad as she had initially thought. While her appearance was undeniably bizarre, the profound joy of her reality washed over her: the thing that made her happy the most was that she was able to stand and walk again like she used to. The paralysis was gone, replaced by a strength she hadn't felt since her track days.
