Seeing my girlfriend's beautiful naked body laying on the warm sand, I thought the one thing that could make her sexier was if she was a mermaid.
I wished Kasey would transform into a mermaid, she would be okay with her new form, and nobody would think anything was unusual about her being a mermaid.
As I sat down on the beach next to my girlfriend and enjoyed the view of her body. As I watched, her toes melded together and her feet flattened. Her knees and ankles seemed to disappear as her legs melded together. Soon all evidence of her long lengs was gone, replaced by a tail and tailfin. It was much like a classic mermaid's tail, except the color and texture did not appear to be changed from what her legs had been - only the shape. I could wish it to a more classic look, but at least for now I liked it this way.
I reached over and ran my hand up Kasey's tail; it felt like smooth human skin.
"That feels good..." she said.
I felt rock hard. I wished nobody would notice me and Kasey having sex.
I was about to start doing more than just rubbing her tail when something occured me: I had repeatedly changed my girlfriend and modified her thoughts too. If we were going to be intimate, I wanted it be honest.
"I love you, Kasey."
"I love you too."
I wished Kasey would know all the wishes I had made so far and that I did not want to hurt her.
Kasey suddenly looked around, but saw that of the few people on the beach nobody was paying any attention to her except me. She glared at me.
