I am a young pirate, my father has allowed me to sail with my own crew, in the middle of a calm night sea, I was alone on the deck of the ship while looking at the ocean reflecting the moonlight

Suddenly there was a tail that splashed water until it hit my face. I was shocked then I immediately looked down longer "what was that, it looks like a big fish, I hope it won't rock the ship" I was still silent while looking down at the sea

I saw a glimps mermaid passing in front of me, I shifted to a lower deck to see more clearly, when I saw the mermaid starting to show her head, I was stunned "Damn ... father is right, they are very beautiful" I saw the mermaid looking at me and smiling
