This is Marta - (Daughter of the Sea) Mermaid Monster Girl.
As part of the race of mermaids, Marta normally exhibit firm behavior that is full of confidence, but also stubborn by nature. She is not aggressive about sex with human males.
In fact her sexuality on the surface is unbecoming of a monster. As with her stubbornness, comes sexual curiosity. Thus, once she start having sex, she exhibit strong lust, as is the case with most monsters, using their beautiful bodies to enthrall a man and bind him to her will.
Will you tame her? Or will she tame you instead?
