You watch as the boys legs buckle beneath him. His hands struggle with the metal embedded in his chest.
With a loud rip his struggles begin to rip his shirt off exposing his chest. If you werent panic stricken you would have been even more attracted to his smooth skin and lean build. Another sound draws your attention away from his chest. A ripping sound again.
He bucks on the floor a little, his legs rising up and then flopping down. With a little gasp of breath and then a moan he feels his bones begin to shift. His thighs have swollen making his pants tighter and tighter, they are painfully tight before they split at the seems and his legs are set free. The tear travels down to his feet where his shoes rip with a loud popping sound as the leather and rubber is torn apart.
His legs buck again, but differnt this time. You can see they move as one, his feet appear to be connected. The skin is slowly merging as the machine hums away and the boy grunts a bit watching the change come over him.
His feet are fully merged in to one strange looking appendage as his underwear splits with a rip and you see his crotch exposed. The flesh looks odd though. His dick and balls are resting on his thighs which are joined together. You can see the skin moving downward merging his two legs together. The boy legs go of the metal claw for the first time and moves his hands down to his legs and runs his hands across them, feeling the slowly disappearing gap between his legs. He jerks his knees once more and a crunching of bone comes from his legs as his skeleton is re-shaped.
"My legs!" He gasps breathing heavily "They are... a tail... whats happening to me?" He looks up at you and pleads for assistance. You dont know what to say. You just look back at him.
"Im sorry. I dont.. I cant... what should I do?" You respond.
"Get this thing out of my... argh!" the boy jerks again and this time his legs move differently, more fluid. You can see that there are new joints in there. His feet slowly extend spreading outward forming a fan that has delicate skin stretched between its boney tracery, what used to be his toes. His tail flops on the ground again.
"Oh god." He says and his hands go to his crotch again cupping his manhood as he closes his eyes tight, wincing in pain.
You see something odd at his waist, his skin is turning darker, then greener, spreading downward. Soon you see shiny scales start to gently emerge from his flesh coating him. Fish scales in green and blue with a shimmer in the light spread over his legs from his waist down.
He moves his hands and you make a little sound in the back of your throat at the shock of what you see. His fingers are webbed, and his nails are slightly pointed. Under his hands are smooth scales, his genitals are totally gone leaving only a smooth fish tail emerging from his waist downward.
He looks at his hands and makes a squeak in his throat, then pulls his hands up to his throat, choking again. He looks at you, rasping. His ability to speak is gone. You see his eyes turn black and grow a little wider as his teeth extend slowly downward in to tiny fangs. He flops his tail and falls over on to his face with a twist of his torso. Behind him you can see his tail has a ridge that runs its entire length. From the boys arms a ridge is pushing upward, and from his back at the same time you see a small fin rising from his spine.
The boy tries to drag himself towards you with one hand, reaching for you with the other as he opens and closes his mouth tring to speak.
The machine hums once, then jitters a little.
