It took you a second but you noticed a plank that you could use to defend yourself, it's better than nothing right? But as soon as you reach for it you instantly feel a splash on your shoulder - you've been hit with the transformation water. The student that did this to you seemed smug about it, as he slowly backed away from you, you started feeling heat rising all over your body. You knew it was too late to help it. You involuntarily gotten weak in seconds and fallen onto floor in sweat. You were frightened about what you would become, but you didn't want to panic and lose yourself. First you felt itchiness all over your body as all your body hair started slowly falling out in clumps. You shook your head dazed a bit as last of your hair fallen out. You brought your hands in front of you to watch as your fingers slowly started painfully merging together fusing with your flesh and becoming stubs. You felt as your toenails also started melding together, you couldn't move them anymore as they all fused together. Your feet thinning out and becoming stumps as your shoes and socks slid off. You had a moment of peace as the changes so to say charged. You glanced at the direction where the student stood, he insolently recorded you changing from a ten meters distance. Not only were your old self ceasing to exist, you were becoming some sort of animal, but you were also humiliated by that moron who did this to you in the first place. You didn't have time to ponder about this as you felt your vertebrae slowly popping altogether. You groaned as you slid on the floor slowly growing in length, becoming longer and slightly slimmer. Not only you lost all your fingers and toes, your appendages started aching as they all started contorting, drawn towards your torso and merging with it. Your shins shortening and melting, calves, thighs fusing with your torso and soon disappearing completely. Your hand stumps soon followed as they shortened and contorted painfully becoming drawn closer to your torso and there fused with it. You lost your balance and fallen head first onto the floor, feeling a few sharp pains in your mouth. "Wh-whatf...?" - You managed to lisp as you felt something loose and hard in your mouth. You spitted it out - it was your teeth, and not just one, you spat the rest and soon all of your teeth loosened up and fell out of your gums onto the floor. You lied there splayed with no arms and legs as they finished becoming your torso, nothing left of them. You were then reminded of your altering spine as your head slowly started sliding away from your torso. Your neck throbbed as it extended itself, gaining more length and vertebrae. Your torso followed suit, thinning out slightly and becoming longer, organs shifting uncomfortably. You let out a yelp as you felt something start to twinge right above your bare butt. You managed to tilt your head slightly and catch a sight of something slowly growing out of your tailbone, actually it was your tailbone changing and growing out pressing on your skin and carrying some of your flesh with it, stretching it and becoming a short tail nub. You felt your organs down there shift as your buttcheeks were absorbed by the stretching mass of flesh that was forming your tail. Your penis slowly started diminishing in size and as it did it felt really freaky as it started splitting in half. Your penis became split in two, now it had two tips which grew spike like protrusions. You twinged and blushed unwillingly as your new equipment started burrowing inside you, into a forming cloaca. Your balls that still were mostly unchanged now started deforming and becoming smaller as they were pulled inside you. Your empty ballsack started melding with your "groin" becoming taut skin next to the cloaca hole where your penis was. You cringed at the sensations happy they were over. But then you suddenly jolted as you felt your asshole twinging as it migrated lower, closer to your cloaca. As it approached it, it slowly started fusing with it pleasurably, becoming a snake cloaca. The entire transformation was painful, but this part made you stubbornly horny. You felt your cloaca fill up as your hemipenes came out of it erect. You then unexpectedly felt your spine expanding. Each growth spurt making your body so much longer made you hornier as your spine pulled your tail further away from your head. Lost in ecstasy you barely felt your head change position on your neck as it became forward faced. Your hemipenes slid against the rough floor as your head started shifting. You felt your nose pressing more and more onto your face as it melded together with it, your entire face slenderizing as your eyes were forced to move to the sides of your head as your nose started forming your snout, growing in size. Your toothless mouth stretched wider, your lips pressing against it tight and disappearing. You felt as two sharp protrusions grew from your gums agonizingly slow as they became your fangs connected to your forming venom sacks bellow your eyes. Your tongue wiggling around from pleasure contorted as it became thinner and divided at the end, forked tips forming at the end. Your weirdly human eyes on the sides of your malformed head started changing into much smaller and beadier eyes of a snake, slitted as well. What was left of your human nose flattened on your snake snout and became slits on it. A crunching sound caught by your ears was the last thing you heard so well as they started folding and getting absorbed by your head, becoming barely visible holes that were barely there and caught much less sounds. Your entire body writhed as it thinned out becoming almost the same width thoroughly. Your inhuman head felt as if it was hit with a hammer as your brain lobes shrank and flattened and finished forming a snake head. Then you felt tingling all over your human skin covered body as it grew snake scales. It tingled so much, you felt so many sensations over your still soft freshly transformed body that your as yet erect hemipenes throbbed. You started writihing on the rough floor as the black scales finished covering your entire body and then you finally came for the first time as a snake with a massive cumulated orgasm. And with that the last changes finished fully transforming you into a snake, perhaps some viper that you didn't know the name of. Either way, you slowly came to your sense, first of all glad that your "human mind" remained and you didn't lose it at least. Though that didn't help you that much in your situation, you just became a pretty huge snake. The person who did this to you might still be there. What will you do?
