A white beam shot out of the remote, bounced off the mirror and struck Tricia at her waist. Immediately, she felt a tingling and a pulling at the base of her spine. She realized that she hadn't thought the whole idea through and started to unbutton her shorts with her empty hand. She wasn't fast enough. Pain shot up her back as her tail started growing in the cramped confines of the denim. The remote fell out of her hand as she struggled to remove her shorts with both hands. Out of the corner of her eye, she saw the remote strike the ground and another beam bounce off the mirror. This beam hit her right above the eyes, almost blinding her.
She didn't have time to worry about that, not when her new tail was screaming in pain. She finally managed to open the zipper, though now she was getting quite a headache, and she pulled her shorts down. They plopped to the floor as the pain in her spine disappeared and a rope of black fur dropped from her back. She could see it in the mirror: A thick cow's tail that ended in a cuff of bright red hair. It even had a few small red spots peppering the black fur on the ropey part. It looked exactly as she had programmed it, one and a half inches thick and reaching down all the way to her ankles. She flexed a few muscles in her back and watched the long tail make subtle waves in the air. It was incredible.
Then she noticed a different feeling. This was coming from her head. She looked up at the mirror and gasped. No wonder she had a headache. When the remote had struck her head, it initiated more changes. Her hair had transformed dramatically. It was much thicker, and had grown almost to her waist. It was the same fiery red as the cuff of her tail. Out from the top poked two black cow horns. When she gasped in surprise, two long, furry, black ears flew up out of her red tresses and flopped down again. She realized she could twitch these just like her tail.
All in all, she enjoyed the changes, both the ones she had made on purpose and by accident. She twirled around, feeling her hair and tail swinging and slapping, swinging and slapping. The horns made a cool crown, and she loved how the color scheme was working.
The more she admired herself in the mirror, the more she wanted to make further improvements. She picked the remote off the floor and pondered her next move.
