"What that have to do with me?"
"It's funny that you ask, Kevin." The mermaid responded. "You see, I'm not the only one to have that kind of past."
"The mermaid that was my girlfriend at the time was very supportive, helping me adjust to my new life. But she rapidly learned that since I wasn't male anymore, she was seeing me more as some sort of sister than a lover, so we ended our relation."
"I'm sorry to hear that." Interrupted Kevin.
"Don't be, with my sex-change, we weren't a match for etch other anymore. Beside, she is the best straight friend a gay mermaid can ask for! She IS the one that have suggested me to go to one of these ex-humans support groups. And trust me, that have greatly helped me! And not only to meet my new girlfriend."
"Said mermaid have it far worst than I have. I know it isn't hard: I can go on earth more time than naturals, without having to go back in the ocean, after all. But… But the time between her absorption of the potion and her operation was so long that… That the fact she is alive and well is nothing short of a miracle! Because of that delay, she can't even breath air, preventing any chance at all to speak to her family!"
"Her family… She speak so much of it, especially of her twin brother." Added Gisela. "I wanted to see him at least one time, so I decided to go to a marine conference as a xeno-biologist. Her brother is a brilliant marine biologist, you see. He surprised me when I got the chance to speak with him, and confessed fantasizing about mermaids. When she eared about it, my beloved was happy and got that strange idea.
You see, we always dreamed of having a child of our own. But even if both of us used to be male, since none of us are anymore… Except that my love got an identical twin."
"WAIT!!!" Exclaimed Kevin, chocked. "You mean that your girlfriend is my brother Marc?!?"
At that the mermaid giggled. "Yep! That's who my lovely Maria is to you!"
