You feel bloated, and terribly dry. You need water, you instinctively head for the pool. You flop like a fish sidling like a snake on your belly making your way to the sliding door to the pool area. You skin is sensitive and rubbery to the touch. You feel yourself swelling up. Strangely, you feel lighter, and easily propel yourself toward the pool. The cool water feels great against your skin. You float on the surface of the pool lazing in the sun. You start to feel warm and decide a dip would be nice. But you cannot break the water's surface.
You open your eyes are startled to find that your body is now a rectangular pool float with arms, a mermaid's tail and your head. Your new breasts seem to form a pillow.
You hear a voice.
"I wonder when they got this new mermaid pool float?"
You recognize the voice of the girl next door. She's slightly younger than you and very attractive. They neighbors don't have a pool and she sometimes comes over to swim in yours, especially on a hot day like today.
