As the transformation completes, you just admire your body for a moment, then burst in tears of joy. You jump at the mermaid, hugging her tightly.
"Oh my god... thank you, THANK YOU!" you shout. "I've always wanted to be a mermaid... thank you so much by making my wish come true..." you say, crying uncontrollably on her shoulder.
"Don't worry, my dear... cry all you want... relieve yourself..." she tells you in a quiet and soothing voice. You keep crying for what seems like an hour until you finally calm down and talk to her.
"So... how are mermaids in real life? Could you please... teach me the essentials?" you ask her, still sobbing slightly.
"Of course. We are all peaceful and calm, because us mermaids can't die or get killed. We are inmortal and eternally young. In fact, I am over 300 years old. We live in big cities underwater, which have never been seen by humans, because they have an enchantment which makes them invisible and nonexistant to the human eye. You will never see a mermaid harming anyone, unless they've harmed her first. We are pure, although we have ways of expressing our love. And... we're all females. There aren't male mermaids, but we have a way to mate..." She follows on for hours, explaining everything about the mermaids and their magic, and you just listen cautiously, but never saying a word. That, until you feel obliged to ask:
"I'm sorry, but what's your name?"
"Oh, I realize, I haven't told you that." she giggles. "My name is Vanessa. Most of us have human names... And what's yours?" she asks.
Then you realize you haven't told her yours, but you feel as if you don't need it anymore.
"I don't want to tell you... since I want to stay as a mermaid. But... i'd like to pick the name Sarah. I've always liked it..."
"Well, Sarah, welcome to mermaid life. You'll love it." she says.
You take a moment to look at her, and... my god, she's gorgeous. She's just so pretty, with her long hair and her cute face and her perfect tail... you feel the need to tell her.
"Vanessa... I think i've fallen in love with you..." you tell her shyly.
She then looks at you, and admires your body as well... and then she says...
"I think... I love you too..."
You both hug each other, and embrace in a long, deep, and passionate kiss, which marks that neither of you will ever be alone again.
