John looked over at the shiny, high heels in the corner and he was curious at how a mermaid would change back by putting on heels... If it was real though. The man was still not entirely sure if he was in the kitchen with a real mermaid or just someone in a well-made costume. He wanted to test it out, so he used this opportunity to find out for sure. He walked over to the heels and picked them up all while on the lookout for hidden cameras, just in case this was for a prank show or something. Even if it was, it was the risk he was willing to take, after all, Erin looked pretty convincing earlier. "Sure...um how about your fins?"
"That's great, I am feeling uncomfortable in these anyway" She sounded excited as she flailed her giant fins around. John placed her heels next to Erin and with one swing of her tail, her fins were thrown on top of the heels covering them. If you looked closely, you can make out the indentation through her webbing. John was confused, there was a clear size difference between her fin size and the size of the shoes so he figured that nothing would happen. "Um...Erin"
"Shh! Look" Erin held up her finger, interrupting John from talking any further. A few seconds pass and what happened next caused John to rub his eyes in disbelief. Small sparks were erupting from Erin's fin and then her entire tail grew brighter and brighter. Erin was gasping and groaning meaning she was clearly in pain. John wanted to stand closer to hold her hand but he instead chose to listen to Erin and so he kept watching. Suddenly, her tail split in two and her giant fin were sucked into the contents of the heels like a vacuum, one side for the right and one for the left. When the bright light faded, Erin, who was clutching the chair, looked down at what was her fin. She lifted the left one higher and wriggled her toes and you could see the heel bending up and down. From her ankles to her waist, Erin was still covered in slimy scales but signs of thighs and knees were visible now where they would be on a human. The fish girl slowly stood up using the table for support. A bit out of breath, she stated. "Ha...ha...There...What do you think?"
