Karissa had stopped sobbing and was examining Mitch's ears and tail. The feelings of fear and horror had worn off. There was someone who had the same things happen to them as had happened to her.
Feelings of playfulness and curiosity had replaced fear and horror. She was intrigued by these changes now. For some reason, she had the desire to see what being a donkey was like. It intrigued her, it was somehow seductive and sensual.
"Mitch," Karissa said shyly, "I'm having the odd thought of...well, what would it be like to be a donkey? I've got the ears and the tail. But...I want to feel what it's like to be on all fours." Karissa blushed and pulled her tail to her mouth.
Mitch smiled warmly and hugged her. "That isn't an odd thought at all. And something that I can help with." Mitch smiled, holding the amulet, and wished.
Karissa felt a warm sensation all over her body as soft brown fur sprouted everywhere. Mitch hugged Karissa close, feeling her changing body next to his. The most obvious change was that Karissa was gaining mass, her body filled out with fat, softening edges.
Karissa's neck thickened to hold a lengthening muzzle. She brayed as she lost her ability to speak. Her clothes split off her body as it swelled with fat and muscle. Her arms stiffened into legs, and her hands into hooves.
Shortly, a full female donkey sat a little awkwardly on the couch next to Mitch. Mitch was in heaven, enjoying the sight of his newly transformed girlfriend. He stroked her wondrously soft fur. Karissa, the donkey, brayed in approval and nuzzled Mitch with a large nose.
