Your legs started to burn. You sat down on the sand as you feel your bones begin to shift. Your thighs were starting to swell beneath your damp clothing. Your pants were starting to get tighter. They start to get painfully tight before they started to split at the seams.
The tear travels down to your feet where your shoes rip with a loud sound. "Whats happening to me Clia?" you asked as my skeleton was being reshaped. "Don't worry, its only natural." she said in a calm voice. Your skin starts merging together and they start moving as one. Your feet are fully merged into a appendage.
Your underwear starts to split with a rip leaving your crouch exposed. You cover your crouch in embarrassment aware that Clia was watching your change. "No need to cover it, it will change on it own." Clia said. No idea what she meant you peaked through your hands. You saw that your dick and balls started to join into your new tail.
Your skin was moving down wards fusing your two legs together. You jerk your knees and a crunching of bones comes from your legs. Your feet slowly extend spreading outward forming a fan that has delicate skin stretched between its bony tracery, what used to be your toes. "Oh god." You say and your hands go to your crotch again cupping your manhood as you closes your eyes tight, wincing in pain.
You see something odd at your waist, your skin is turning darker, then bluer, spreading downward.
Soon you see shiny scales start to gently emerge from your flesh coating you. Fish scales in green and blue with a shimmer in the light spread over your legs from your waist down. Your fingers are webbed, and your nails are slightly pointed. Just like Clia's. Under your hands are smooth scales, your genitals are totally gone leaving only a smooth fish tail emerging from your waist downward.
You see your teeth extend slowly downward into tiny fangs. You flop your tail. Behind you you can see your tail has a ridge that runs its entire length. From your arms a ridge is pushing upward, and from your back at the same time you see a small fin rising from your spine. Then to complete the transformation two holes formed on your tail, one on where your crouch use to be and one where your ass use to be, like Clia's but instead she has a slit like a vagina instead.
"Wow Clia is this what your gift done to me?"
