As I watched the nude, busty long-haired blonde try to cover herself I soon got as big a shock as she did.
Her legs were drawn together as if they were magnatized. Then everything below her waist started turning green and scaily. Her legs then fused to form a single appentage, and her feet flattened and thinned, morphing into a tail fin.
She was a mermaid!
With nothing to stand on, she toppled to the ground and sat there.
