The words ring in your ears, they are so tempting, you want to give yourself to this merman...but something in your soul rebels, fights back a hypnotic suggestion.
"Yes, I...wait, NO!" You exclaim in your luxurious female voice, as control rushes back with a shudder. It rocks you like nothing else, like fighting back a deep sleep. Andrew recoils, shocked at this result. You take a few deep breaths of water, as if to clear your head, twitching your tail to distance yourself from this merman.
"You've made me female, you've made me a mermaid, but I am not going to become your mindless whore!" You proclaim. With those words it feels like something in you locks home, and that maybe being a mermaid might not be so bad after all, as long as you are not some concubine...but are there brothers and sisters under similar spells?
