You suddenly heard a crunch under your foot and yelped in the sudden pain. You looked down to see that you had stepped on a lizard which bit hord on to the leg and began to quickly climb its way up the leg into your "SHIT" you shouted as you desperately tried to think of a way to get the lizard out.
While you desperately tried to get the lizard out, you didn't notice changes happening to your body.
You fell over and you watched the reflection in the nearby lake as the changes became visible.
You watched as the flawless skin bubbled before it ripped apart to reveal black scales on the skin underneath. You cried out in pain as your muscles knotted up and you arched your back to yell as 200 pounds of muscles simultaneously bulged out ripping of the remains of your shredded skin and tissues. You felt a cracking as your spine extended and you had grown to a height of 10'8" weighing a total of 350 pounds and a impressive rack of 48DD breasts with a tail close to 9' long.
"Now to thank the the person who did this to me" you said seductively to yourself as you walked away leaving the tattered remains of your human skin.
