“Let’s see what one more will do,” Amy said. She pops another pearl like a piece of candy, and quickly swallows it.
Thankfully the sensations were much more pleasant this time than her gills had been. After about a minute of waiting, she felt a pleasurable tingling sensation, pooling in her hands and feet.
She lifts her hands up out of the water, inspecting them closely to see what is happening. Her fingers grew slightly longer, about an inch, and her nails grew pointed and took on a dark navy sheen. Her palms ached, the bones within groaning as they expanded to be slightly longer and wider. Then, a thin royal blue, partially transparent membrane started to grow between her fingers, slowly sliding its way up to the last knuckle of each finger, leaving the tips free. She ran a finger lightly along the webbing on one hand, finding it felt pliable but strong, almost like rubber. She watched as royal blue scales dotted their way along her fingers and thumbs, stopping about halfway down her palms and the backs of her hands.
The sensations in her feet grew stronger, and Amy closed her eyes, leaning her head back against the edge of the tub, her webbed hands pressing at the sides. Her feet felt like she was getting the best massage in the world and then some. Ripples of pleasure flowed between her toes and soft soles before sliding up her legs to her warm pussy.
She moaned, and her arches groaned back in response as the bones lengthened, growing forward by a few inches. Her soles grew slightly wider and her feet flattened. Amy felt like someone was intimately rubbing and popping each on of her toes. The feeling was incredible, and she darted a clawed hand beneath the water, rubbing her needy vagina.
Her toes stretched forward much like her fingers, but they didn't stop quickly. Her toes grew longer and thinner, looking more like thin filaments. This was especially noticeable her pinkies, which grew around a foot long, while her big toes stopped at about seven inches. Unlike her fingernails, her toenails shrank swiftly out of existence. A semi-transparent membrane began to worm its way between her long flattened toes. It was primarily the same royal blue as the webbing on her hands, but a large yellow patch formed on each foot between where the pinkies and middle toes had been.
Amy rubbed more insistently at her clit as the creaking, rubbery sound of her growing fins filled the room. Images of her and Lina alone in a damp grotto entered her mind unbidden, with her friend rubbing, massaging, and even licking her fins. Amy moaned loudly, the tail end of it ending in a gurgle as he face slid beneath the surface of the water without her noticing.
As the webbing finished forming, it created a sloping shape at the ends of her aquatic feet, starting at a point where her pinkies used to be, and angling to a rounded curve at the remnants of her big toes. The general shape of her feet flattened, becoming more fin-like, while her heels and some of her soles remained defined, to let her walk upright. More royal blue scales materialized on the skin of her feet, tapering off as they reached her ankles.
As the fins that were her feet completed their transformation, Amy came, making a restrained, high-pitched squeak as she did. She lay there in the tub for a few minutes, in a daze. After a bit she realized she was still underwater, and she could taste her own juices that were swirling around in the tub now.
She sits up quickly, angling her feet up out of the water. My 'flippers' she corrected herself as she took them in. They were gorgeous, and she recognized the pattern of a regal tang from her last trip the aquarium. Light shone faintly through their semi-transparent forms. Each looked like one half of a full fin, or like the fanciest swimming fins one had ever seen. Amy tried to wiggle her toes, but the edge of the flipper only undulated slightly in response.
"This is so cool," she says to herself, as she reaches forward to rub her feet, enjoying the feeling of the firm membranous fins.
Amy was amazed at the sight of her new flippers and webbed hands, and she was already imagining how much fun it would be
to use them. She blushed a little when she thought back to the wet fantasy that had taken her while she changed, but she pushed it to the back of her mind and focused back on the box. She couldn't believe this was just two pearls.
Maybe just one more...she thinks to herself, reaching toward the box with blue clawed fingers.
