Erika didn't know what to do. She stood in front of her mirror, watching as the hair spread up her front. Thankfully the hair stopped just below her breasts. Which were quickly ballooning outward themselves. Awestruck, Erika's mouth hung open watching her chest grow and grow until her breasts were as big as bowling balls, if not bigger.
"Oh my...ow!" she cried, feeling a sharp pain at the top of her head. Erika's hands went up, and found two short protrusions at her temples. It didn't take long before she realized they were horns. Then her ears pulled to the sides, and started twitching of their own accord.
Erika had an animal's ears. What kind of animal she couldn't say. A barnyard animal? A sheep, cow or goat maybe... She doubled over in pain as her legs started to transform. Her thighs were covered in long brown hairs. The fur continued to grow down her legs, which had lost their human form.
Her calves were thin, and her feet looked as though they were balling up. Erika didn't have toes anymore. She had a thick black substance covering the bottom of her appendages. A sudden pop, and Erika's knees changed their orientation. Another pop, and Erika felt something rubbing against her butt.
A shaky hand went back and grasped something thick and furry. When she gave a gentle tug she yelped. It was attached to her! She had a tail. Granted a small tail, but a tail. It was barely six inches long. Erika took a better look at her feet. The hooves were cloven, small and actually kind of dainty.
Just like that the changes were over. Erika got to her hooves and looked at herself. Her lower half was obviously animal, while she had furred ears and horns. Upon closer inspection, she saw that her eyes were different as well. Her pupils had turned into horizontal black rectangles.
"Just like a goat! Oh god I'm a goat person! What are those called...? Martyrs? No, satyrs! I'm a satyr!"
