You run inside to meet her parents before they come looking for Amy. You arrive in the kitchen as they come around form the front door.
“Oh! You’re already here!” Amy’s mother said in surprise. “Bill, did you tell Amy that we were going out tonight?”
“No, I didn’t, but I imagine she would have invited him over anyway.. I”ll bet she’s swimming.” Bill sighed. “Well, the surprise is sprung. We’re off to celebrate - dinner, show, hotel, the works.” He leaned in to kiss his wife. “Pizza’s paid for and on the way, you guys have the place to yourselves. I just need to grab a couple bags, and then we’re back out the door.” He finished saying as he rounded the corner to the stairs. Peaking back around the corner he added sternly “Don’t let me catch you here tomorrow.”
Amy’s mother stepped off to freshen up before leaving again. She waved and blew kisses blindly out the back window, towards the pool, the glare from the lights preventing her from seeing whether or not her daughter received them. “Tell Amy the pizza will be here soon! She knows she’s not supposed to eat in the pool..” The door slammed shut and locked.
You return to the pool and explain to Amy that her parents are gone for the evening, and won’t be back until sometime tomorrow. You are somewhat relieved, but she seems no different.
“At least we have time to figure this out without them here…”
“Figure this out!!?? What do you need to figure out!? I’m the one without legs!” She stormed back at you. She pulled herself out of the water enough for you to see the grey stretching from her breasts down to past her thighs into the water. You notice her silvery grey fluke breaking the water behind her.
