"Lina," Amy whispered when she felt her feet tingling. "Could you keep an eye on Jessica? Make sure she doesn't freak out too badly?"
Lina nodded in understanding, then approached Jessica, who was flattening out the wrinkles in her sleeping bag.
"It's started, Jess," Amy said. She sat on the floor, careful not to land on her tail, as she completely lost feeling in her feet. "Take a look at this." Amy pulled the back of her shirt up and turned her upper body slightly so that Jessica could see the magic circle glow red.
Jessica's face showed no emotion for a second, then she blinked. "No, I must be imagining..." Her eyes fell on Amy's socks, which were starting to bulge. Her feet seemed to be widening, straining the white cotton. Jessica let out a quick yelp when the fabric burst to reveal dark cloven hooves which were growing to replace Amy's toes. Her feet lengthened, her ankle forming a new joint in her leg which would no longer touch the ground.
Jessica tried to stand up, but Lina was right behind her to keep her exactly where she was. "Let go of me! Get me out of here!" Jessica shouted. "This is insane! What's happening to you?!"
All around Amy's former feet, white fur emerged. Amy shivered at the sensation. "It feels like someone's poking thousands of needles in me," she stammered. She pulled up the cuffs of her pants to watch more fur grow in. Irregular black spots appeared in some places. She could feel the fur growing all the way up to her waist before the tingling started to die down.
Jessica, meanwhile, was screaming incessantly. Lina tried to shout above the noise to tell her nothing bad was happening. As Amy came out of her transformation, she became aware of Jessica's insane state and immediately joined Lina in trying to calm her down.
"I'm fine! There's nothing wrong, Jess!" She tried smiling broadly, and she even shimmied further away from her in case Jessica saw her as a monster like Mrs. Henderson did. In a minute, Jessica clammed up. She panted and lowered her eyes so she didn't have to see Amy.
Lina said "I'm gonna let go now, but promise you won't try to run away or anything. Everything's fine." Jessica nodded and Lina let go of her arms. She sat there silently for a few minutes. In the meantime, Amy attempted to stand. It was shaky at first, but new instincts kicked in and in no time she was walking around on her hooves as if she'd always had them. She thought she owed some of this ease to her tail as well.
Finally, Jessica looked up at Amy and stood. She carefully walked toward her, holding out an arm. Amy stood still and let Jessica rub her hand over a horn and an ear. The ear involuntarily twitched, which made Jessica jump back. "That's amazing!" she gasped. "I can't believe this is real! You've got horns and fur and a tail!"
Her amazement gave Amy pride in her new form, and she struck a confident pose without realizing it.
"How much further are you going to let this take you?" Lina questioned skeptically. "I mean, that was a pretty huge change all of a sudden. What if it takes your hands next?"
Amy crossed her still-human arms and snorted out of her nose. "I haven't decided, but don't start telling me these changes are ugly."
"I'm not, I'm just hoping my best friend isn't going to start mooing and eating grass."
"Why did you choose a cow?" Jessica spoke up. "I'm not calling you ugly, but there are so many graceful and beautiful animals out there. I'd pick a bird, or a cheetah, definitely not a cow."
"You know, in some places people have a lot of respect for cows," Amy defended. "Some people might even see me as a goddess."
"Okay, let's not get too full of ourselves," Lina interjected. "Hey, did your hips fill out a little?"
Everyone was now staring at Amy's waist. Her black pants seemed to be tighter in her upper legs than before. "It does feel a little tight," Amy admitted. "My bra, too. But I've been feeling that since this morning." She tried to adjust her pants to the new shape of her legs, and was glad the outfit she had brought to wear the next day included shorts.
Lina gave Amy a curious look, but decided to move on. "It's lucky my parents are out seeing a movie right now, your screaming would have had them calling 911."
"Like I could have been prepared for this!" Jessica responded. "Didn't you freak out at first?"
"Yeah, a little," Lina said. "But a tail is less dramatic of a change than legs and feet."
"Hooves," Amy corrected with a grin. "So are we gonna keep gawking at my body, or are we going to have ourselves a sleep-over?"
