"Well today was the first of three days" Katie said.
You nod thinking of stories of were-wolves that had them transforming for three nights. This leads you to another thought. Looking directly into Katie's eyes you say "You said that you were swimming for most of the day. Why couldn't you transform back and see me in the daytime? Why have you disappeared during the days?"
"Because the transformation isn't limited to the nighttime when the moon is up" a female voice said. Looking to where the voice came from you see another mermaid swimming up to you and Katie. "You see" she continued, "for a were-mermaid it's the gravitational pull of the moon and the sun directly opposite of each other with Earth in the middle. This is unlike were-wolves were the reflected light of he full moon triggers their transformation."
Katie smiled and said "Bobby, I want to introduce you to the mermaid who saved my life. This is Kasheala. She's like my second mother."
"Well you certainly spend enough time at my home to be my daughter" Kasheala said. "I see you've made another were-mermaid."
"Yes but something went wrong" Katie said. "Bobby was male before I turned him into a were-mermaid."
"Was he in any danger of drowning?" Kasheala asked.
"No" Katie said. "He asked me to transform him."
"I see" Kasheala said rubbing her chin and holding an arm across herself. "So you could have gotten a merman or were-merman to kiss him then he would be a were-merman instead of a were-mermaid."
"Wait a minute" you said holding up a hand. "I was not going to let some guy kiss me." The thought of a guy kissing you was repugnant in your mind. It was so repugnant that you wanted to throw up.
"Well it's a moot point now" Kasheala said. "You're female now and you can't go back to being male."
Katie looked horrified again and said "Oh Bobby I'm so sorry. I didn't know you would become a woman and be stuck as one."
You cupped Katie's chin and gently and kindly said "It's alright Katie. I knew there was a chance of this happening."
"But what will you do?" Katie asked. "Your life is basically over."
"My -male- life is over" you said. "Though as long as I have you that doesn't matter."
Katie smiled and kissed you holding onto you like she was afraid you would swim away. When she broke the kiss she asked "But what are you going to do? You don't have a job now since no one will believe that you're you. And what about your family? They won't understand what's happened to you."
"Well I'm not sure about my job but my family is a bit more open minded than ou think" you said smiling. "I'm sure they'll understand."
"I have a couple suggestions for you" Kasheala said. "The first one is there are some government officials who are also were- mermaids or were-mermen. They can help set you up with a new identity and job. If your family accepts you as female now that will be an added bonus. The other option applies to both of you." She paused seeming to gather some courage for what she was about to say next. "You could decide to live your lives in the sea and become two of those that have mysteriously disappeared without a trace. Of course this means that you wouldn't be able to talk to your families again. It's your choice what you want to do."
