The phone rand for a few seconds before being picked up by your girlfriend. "Hello, this is Amy speaking." You colld tell she had the phone on speeker as it was picking up more background noice than it usaly does.
"Amy, where are you right now?" You asked her, a sence of urgency raising as you where not sure how she would react and you thought that you should explane it to her.
"I'm in my pool, why?" You started to walk to you car, your pace faster than normal.
"I need to tell you something I will be over soon, love you." You got into your car, as you spoke to her and hearing her say that she would see you later before hanging up, that last sentence that she spoke had a different tone to it than her normal tone of voice, it was a little more panicked. You drove to her house arriving in a few minuets, you started to think if she was already a mermaid or not. You ran around the side of her house to see that Amy was sitting on the side of the pool shaking a bit. As you walked closer you realized that her legs where gray like a dolphin's skin and her feet where more fanned out like two separate half's of a fin. You opened the gate, once she heard you she slipped into the water, not wanting you to freak out when you saw her legs.
"Hey John." She put on a fake smile, her arms folded and resting on the edge of the pool.
"Hi Amy, are you ok." You bent down to be closer to eye level with her.
"Please don't freak out." She sighed, trying to separate her legs so she could climb up but they were fused together. She then spun around, pushing herself out of the water and onto the edge of the pool. Her legs where fused, but still there, it was only a small part that was fused. She hid her face, not wanting to know how you would react to this.
"Why would I?" You asked smiling, you wrapped your arms around her, she smiled back but it didn't take her to long to get uncomfortable sitting down. She wiggled free of your grasp, her legs becoming more and more like one tail. On the back of her tail was a small dorsal fin and it was growing quite rapidly with it soon reaching it full size coming a fair was below her bikini top. "I found a genie today, and he said I could transform someone or myself, temporary or permanently, chose to transform you permanently into the mythical creature of your dreams." You blurted out to her.
"How will I explain this to mum and dad." She shook her head and her smile faded, there was no doubt that she was fine with this but it was clear that her parents worried her the most, and they never did like you so that was only going to make it harder. Then another car drove up the driveway, her parents. You gave her a quick kiss to try and show that you would take care of it.
