Succubus Mermaid

For MegaGundamMan 

"I'm so hungry tonight... I hear human essence is the tastiest there is! If a ship comes my way, I could whip up a tempest with my magic!" 

This was made for a muroPLZ thread. The concept of a succubus mermaid sounds interesting. It's similar to a siren, only your death at the succubus mermaid's hands would be more pleasurable. Whether or not she would actually kill you depends on her disposition. She could be friendly, caring and offering you protection, if you surrender some of your energy to her as a deal, that is.
