Patrick lowwered his head as he blushed. " Well Millie, I was kind of wondering.." He trailed off, which made his sister arch an eye brow. "Yes?" She asked him. ".. If I could be a mermaid like you?" H asked. Millie gave a cocked smile. " You want to be a girl?" She asked as Patrick nodded. Millie slid closer to Patrick and drew him close into a hug. "I'd love to have a sister." She said as she tapped into hermermaid instincts for the power to transform her brother into her newest Mermaid sister. Millie started to sing a wordless melody as Patrick started to feel tingilling inside as a tail consumed his legs, as it moved upwards. Patrick felt his groin being pulled into his body and twist around iuntil he was now a she. Her nair grew longer as it fell foward to cover her chest. "Parick no longer suits you little sister, how about Patrica or patty for short?" She asked. Patty giggled. I love it." She said, jumping into the water that was now her home. "I'm Patty the little mermaid!" She declared.
