You groan as you slowly wake up, putting your hand on your head and rubbing it to try and relive the splitting headache you had. "Sssssso, you have awakened human..." Someone said with a hiss as you looked up confused before yelping in fear.
A large snake was coiled up in front of you, it's eyes staring at you with an alien intelligence as it spoke again. "Not many dare to try and enter my cave... all that have entered have never left." The snake hissed as he stared at you, you started backing up before you hit the cave wall and tried to stay as far away from the snake as possible.
"But I've been getting bored anyway... I ssssupposssse it'ssss time I have a little fun." The snake hissed as it lashed at you. You yelled in fear as the snake ripped your clothes with it's fangs, tearing them all off and leaving you naked before it slithered back and coiled up again. "Let it begin." The snake said as it watched you.
You were breathing heavily in fear as you noticed your now naked form. Looking at yourself you didn't feel any different, other then your dick going fully erect quickly.
But that was just the beginning, watching in fear you saw your dick start to grow, becoming longer as small green scales formed on it. You had a sudden sense of fear as your dick started to move on it's own, curling up and turning the head of your dick towards your face.
Watching in fear and awe you saw two small eyes form on your dick's head, the tiny hole on the end of your dick sprout a tiny forked tongue as your dick's head flattened and turned into a snake's head. The snake hissed at you as you screamed, your balls being pulled up your dick-snake's body and becoming a pair of serpentine hempitimes as your dick finished extending into a full three foot long snake. With one large pull, you screamed as the snake your dick had become pulled off your body, leaving a hole in your crotch as the snake slithered over to the larger snake before leaving to go hunt.
"What!" You screamed as you looked down at your bare crotch in fear. "This is only the beginning. All your limbssss ssssshall become ssssnakessss... and then one final change will happen that I will perssssonally ensssssure." The large snake hissed as you groaned in pain, feeling the next changes.
Looking down at your legs you felt yourself lose control over them as green scales erupted across them, your feet meshing into blobs before turning into snake heads and looking at you and hissing. New colacas formed on the twin snakes as they pulled. You screamed as the snakes your legs had become pulled out of your body, leaving you without legs as you cried from the pain.
But there was no time to rest as your arms started to act without your control, copying your legs as your hands become a pair of snake heads that hissed at you before they pulled out of your body, leaving you crying in pain and completely limbless.
The large snake then slithered over to you before gently turning you over and curling around you. "It will be over ssssoon... now for the final act." he hissed as you looked into his eyes with fear.
Very quickly the snake liked up his epitomes with your new hole in place of your dick, penetrating you with all his might as you screamed in pleasure. The hole shifting into a snake's colacta as the snake thrust in and out of your new hole. You cried in pain and pleasure as you felt your spine start to extend, pushing out into a long tail that grew large enough to replace your legs. You could only scream at what was to come next
