"I think I'll go first." The two women walked towards the shoreline, stopping next to a small, rocky island. They stood there for a moment staring at one another. Then Carol sat down, looked at her legs one last time, and gulped down the blue liquid, waiting for her transformation to begin. Mary watched her aunt's legs. She wondered what would happen to them during her transformation.Then the scales started to appear. They began at her feet, and worked their way up her shins, her calves, and then her thighs, then knees. Mary stared as her aunt's feet became webbed. Then suddenly Carol's legs were forced together, and she cried out in pleasure as the scaly skin fused, starting with her thighs, then moving up her body, ending with a new coat of scales around her stomach. She was now sitting there, a beautiful blue fishtail with red scales around the edges, a perfect, perfect tail.
Mary stared at her in jealousy, but knew that her turn was next. She refilled the vial. She sat down, and drank.She waited for her transformation to begin, then felt it happen as the liquid went down her throat and into her stomach. She could feel her legs throb and spasm with pleasure. She was filled with desire, wanting to be a mermaid, one with the sea. She wanted nothing else but to be free, to be one with the water. And then she felt it. A wave of ecstasy going through her entire body. The feeling of scales on her legs was absolutely orgasmic as they popped into existence, one by one. She watched mesmerized as they raced down her legs from her hips to her ankles. She screamed in ecstasy, her legs shuddering and twitching. She felt another wave of ecstasy as they locked for good. Then she was finished. She looked down at her tail, and gasped. She had a tail the color of the sea, beautiful and iridescent. She turned it around to admire it, then slapped it against the sand in glee. She wanted nothing more than to swim around, laughing and having fun.
