"I'm sorry, Clia: you are beautiful but I'm not ready to abandon life on land."
You take the stone from Clia, who is clearly disappointed.
"I feel you are missing a wonderful world beneath the sea. But perhaps I in time will understand why you wont abandon the surface world..."
"Perhaps? But it's hard to get around up here without legs."
"Precisely."
The two of you have been sitting on the rocks where you first saw Clia. Your eyes go wide as you watch, the scales on her tail slowly fade, her tail splits into two legs, and her tail fins turn to feet. Before your eyes a beautiful mermaid has become a beautiful long-legged naked woman. She still has the long red hair, pert 34B breasts, and jade eyes she had as a mermaid.
Clia sees your surprise. "This is not what you expected?"
"I thought I had to choose between becoming a merman or saying goodbye. I didn't realize choosing the stone would turn you into a human so you could join me! Not that I'm complaining..."
"I choose who my mate is, but he must choose in what form we will be mates."
Clia leans over and presses her lips to yours. Still stunned by her transformation and the implications, you recover quickly and kiss her back. As your lips part, you know you are both ready to become mates in more than just name. But before you do, a question occurs to you.
"Clia, how long will you remain human?"
