A Meta-Morph Mistress is your girlfriend on the side, who can change into what ever fantasy you can imagine. From a Honeymoon Honey, to a Porn Star Paramour, or an Elegant Seductress, she is THE uber GFE!
Jack: I heard you got a new mistress.
Me: Yup, Reagan. She is a Meta-Morph Mistress!
Jack: Meta-Morph? WTF is that?
Me: She morphs into your wildest fantasy . . . girlfriend, lover, or companion.
Jack: That's wild!
Me: Yup, she even morphed me!
