A sudden stiffness in her mouth became quite obvious as she wiped the dust from the mirror. Her eyes widened as the reason became obvious. Tiff watched in horror as her front teeth lengthened and grew out popping as they stretched over her bottom lip.
"B-buck teeph!" Tiff exclaimed. Her speak crippled from the new big teeth.
Katie looked her way but something else was bothering Tiff. A sudden pressure on her tail bone that she was distracted from suddenly was released and in its place a fullness and a small rope-like sensation filled the back of her panties.
"Haw?" Tiff gasped reaching back under her skirt and pulled out whatever it was. A second time her eyes widened with the sight of a long tail pushing out of her tail bone. A horse's tail... no... this belonged to a donkey. "Katie! Help me!?" Tiff asked out toward to her friend who was staring in awe, her finger pointing toward her head where a new sensation in her ears has developed.
