You were a Merperson and your parents have always told you not to go to the surface, but somehow you found yourself there... On the deck of a boat.

"What a find..." The Pirate captain kneels down and strokes your tail as you squirm in the nets they caught you in "I wonder how much a pretty thing like you will go for."

He smirks, and a couple of his crewmates chuckle. He keeps his eyes on you, standing back up. This was probably the best catch of the year!
