A white beam of energy shot out of the remote, bouncing off the mirror before striking Tricia at her waist.
Almost 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.
As she struggled to remove her shorts with both hands, the remote fell out of her grip. Out of the corner of her eye, she saw the remote strike the ground. Another white energy beam shot out of it, bouncing off the mirror at a harsh angle and reflecting up towards her head! 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 felt like someone was scratching her scalp and tugging at her ears, and she pulled her shorts down. They plopped to the floor as the pain in her spine disappeared and a mass of pastel hair flumped out behind her. She could see it in the mirror: A fluffy horse's tail made up of soft, pastel mint green hairs.
It looked exactly as she had programmed it with soft, colorful hair that reached down to just past the backs of her knees. She flexed a few muscles in her back and watched the long, elegant tail make subtle undulations in the in the air. The waving of the long hairs was almost hypnotic, It was incredible. She giggled slightly and was shaken from the beauty as the tips of the tail rubbed softly against her skin.
Then she noticed a different feeling, this time 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 wilder, and had grown almost to her waist. It was the same pastel mint color as her new tail. When she gasped in surprise, two long furless equine ears twitched their way out from under her green locks. With a little focus and effort, Tricia 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 about and slapping against her back and legs, respectively. She loved how the pastel color complimented her complexion.
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.
