Unfortunately, no matter how she dabbed up the contents of the vial, the oily film wasn't coming off. She gave up and just decided to return home for a clean outfit. Leaving the parking garage, she placed a quick call to work to tell them of her plans, and concentrated on the drive home. Fortunately traffic in this direction wasn't as bad, which was good news as her chest starting to itch. It was almost maddening by the time she got home, so she quickly discarded her clothing and hopped in the shower to wipe of the remains of the vial. As soon as she rinsed off, she felt better. After a few minutes, she turned off the shower and padded to her bedroom wearing just a towel.
But before she pick out new clothing, the itching returned, joined by a tingling in her legs. Unable to maintain her balance, she fell to the carpet, tail flopping like a landed fish. Wait, what!? Her TAIL ??
Where a pair of long slender legs used to be, from her waist down she now sported the tail of a fish, greenish-silver scales sparking, and fins ruffling with the flopping. The itching grew worse, moving to her rib cage. Looking down, she saw slits appear and quickly open up, revealing blood-red gills. A quick tightening in her chest was the next sensation she experienced, as her lungs quickly shrunk and atrophied. Her panicked gasps and tiny shrieks and moans made it clear her lungs were still there so she could make noise, but they no longer appeared to be connected to her breathing process.
Water! I can't breathe out here! She tried to flop and pull herself to the bathroom and to her tub, as that was the closest supply of water she could think of. And if she didn't get her new gills into some water soon, she wasn't going to go anywhere, ever again.
