Amanda stared at her legs in anticipation and waited. For a minute or more nothing seemed to happen and the expression on her face showed a growing sense of disappointment.
"The other transformations worked just fine," she complained, "just my luck that this one'd turn out to be..."
She was cut off in mind flow by a strange churning sound that both of them first took to be her stomach, but then all eyes fell upon Amanda's thighs. The muscles of her upper legs, slender as they were, could clearly be seen beneath the light fabric of her dress as they writhed and shifted. The movement caused her to twist a little at first and then intensified as it pitched her over onto her side.
Amanda fell onto her front and afforded a grand view of the changes that were taking place below her waist. The dress rode up as her hands pulled it up to see what was happening just at the moment her underwear split from the pressure. The flimsy garment had been shredded by the union of her buttocks and thighs into one. The process continued as the mass of Amanda's knees joined together and was followed by a tide of opalescent scales that swept over the reformed limbs.
Soon the transformation reached Amanda's ankles and fused them together a second before the tips of her toes exploded into a tailfin that expanded like an oriental fan to flap desperatly upon the floor.
Exhilerated by the speed and the sight of her transformation into a mermaid, Amanda stripped off her dress and only half paused when she saw the silver webbing between her fingers. Once the dress was off, she watched as her torso was dotted with more scales and felt delicate fins expand from behind her ears.
I looked at the mermaid that sat before me and wondered for the life of me as to what could be going through her head.
"Amanda," I tried to keep my voice level as she flapped her tail at me, "how do you feel?"
