Alexis groaned. Her head pounded, and she couldn't remember the last few hours. She slowly sat up, holding her head in her hand.
"Wh- what the hell? What happened?" the young girl said, slowly opening her eyes. She looked down.
"Wait... what the...?" she trailed off. When she looked down, instead of seeing what she expected - her normal legs - she was met with the huge legs of a clydesdale stallion!
"This- I have to be dreaming!" she panicked. Alexis pinched her arm. Then she pinched it again, and again. "I-i-i wh-why?" she stuttered, flabbergasted by her change. She felt a flurry of new sensations, from the breeze on her fur to the slight twisting of her new tail behind her. Somehow, somewhere deep in her brain, she accepted it. "This is actually pretty rad," she said to herself, running her hand over her furry, oversized, chestnut-colored thigh. She didn't even question her genitalia - something in what must have transformed her was affecting her mind as well as her body. "I didn't think horses were... this big..." she said, amazed by her new lower body.
Alexis decided she should try to stand up. She looked behind her and noticed an outcropping, probably about 12 feet tall, and grabbed hold. She slowly climbed her way up to a standing position, and found that she was about even with the outcropping!
"Wait, horses... aren't generally this tall, right?" she said. She was astounded, being perched atop 12 foot tall horse legs. She noticed she stood at an almost 45 degree angle, however, because of how her spine now attaches to her hips. Alexis looked back, and found most of her view blocked by her equine hindquarters! They were about twice the size of a normal clydesdale's, and prevented her from seeing much behind her. She watched as her tail swished from side to side, mesmerized by her new body.
Alexis then...
