There was a long silence. Emma expected some reaction to her transformation but not this. She impatiently flops her tail.
Suddenly to the three girls surprise, Jessica and Sammy both let out a cooing melody. Their faces are shocked.
Both girls collapsed on the ground. Backs arched, orgasmic singing and all, Emma looks at her friends, confused and aroused at the same time.
What's happening, she thought. They never kissed a mermaid before.....did they?
Almost in synced with each other, Jessica and Sammys breasts expand, shells and scales sprouted, fins fanning, all while moaning and singing. Jessica's scales were pink and Sammy's was purple. It seems that witnessing Emma's transformation caused both of them to unleash their inner mers. They finish their metamorphosis with one last note, as Emma joins in on a beautiful chorus of pleasure.
