"Let me guess." Said Kevin. "You want me to temporarily exchange my manhood with my brother's… Err… Sister's womanhood so you can have a little mer-baby together!"
"I… Didn't think of that possibility." Said a dumbfounded Gisela. "I don't even know if it's possible. But it can be interesting to ask… I will recontact you, Kevin."
"Can… Can you bring a picture of my bro… Sister next time? I wish to know what he… Err… She look like now that he… She is a mermaid." Asked the uncomfortable brother.
"Don't worry, if the worst is to come, a classic sperm donation is all Maria and me want from you." Reassured the mermaid. "And about the photo, I will see what can be done."
"Thanks." He answered.
"Do you have a car, Kevin?" Suddenly asked Gisela. "I learned that Lilia Fisher, the little-sister of my ex-girlfriend, was living in this area. I want to say 'hi'."
At the name of 'Lilia Fisher', Kevin's blood turned cold. "I know Lilia. She dumped me just before I met you at the bar. At least I think she dumped me, with how she threw me out of her house. But with her, you can't be sure…"
At that, Gisela facepalmed. "I don't think she dumped you, she just did the only thing she can to hide her true nature to you, instead of being honest."
Then, a hopeful Kevin asked "You really think so?!?"
