A familiar stinging sensation in her legs pulled Jane away from reading the last few lines of her book. It was a sign that she would soon transform into what she fears most. Fortunately, it was one of those times where she didn't need to run and hide from anyone. She was in charge of the house whilst her husband was at work, her eldest daughter was out with friends and the younger children were deep asleep. Although, she still had the issue of removing some of her clothing otherwise they would be ruined during the shape shift. Another more painful sting was the sign that she needed to hurry. Her time as human was running out.
Jane was born as human and grew up as a human child to a human family but Jane stumbled across a magical bracelet on the beach at age 13. Out of curiosity, she tried it on immediately but was placed under the effects of the bracelets power. Ever since that day, Jane has become a mermaid every time her legs are wet and will still become a mermaid if she doesn't douse her legs in water every 12 hours. She considers this as her "curse" as she has almost been caught many times due to not bathing her legs or getting them wet in the most inappropriate times. Tonight, Jane was busy looking after her children and then she was lost in her fantasy novel so she lost track of time. Jane jumped to her feet. Just a few more seconds until it starts.
Jane rushed to remove her skirt so she can reach her panties and pantyhose underneath. As soon as she slid her skirt off, Jane felt a more painful stinging in her legs indicating the start of the transformation. "Oh no no no" Jane said to herself. She could feel her legs beginning to numb. With the last ounce of strength to stand, Jane pulled down her pantyhose and panties at the same time. Jane collapsed on the sofa when she couldn't feel her legs anymore and she flicked the pantyhose and panties off her ankles. She didn't want to relax in case someone arrived so the worried mother fell to the floor and started crawling to the bathroom. The bad news was the only bath was upstairs and her large busted frame was going to be tough to move with arms alone.
The transformation continued as Jane set from the living room to the stairs. As the legs began the transformation, Jane found it more difficult to drag them. First the bones in her lower body dissolved and disappeared, then her feet began to flatten. Jane tried using will power alone to keep the transformation from progressing but it had no effect. She's tried many times before with no effect either. Her feet were now large fins by the time Jane reached the stairs, just a long climb then she would be free to bathe. As Jane was about to climb the first step, she could hear the entrance door open. It was Amy, Jane's eldest daughter who was just returning from her friends place. "Mom, I'm home". She was in the room next to Jane just about to see if her Mom was in the living room. Jane panicked as she noticed her legs and fins turning a shade of blue. She needed to act fast or her long term secret would be revealed.
"Honey, how are you?" Jane was laying sideways and her torso was the only thing Amy could see. Her legs and fins were stuffed behind a cabinet by the stairs.
"Yeah.. I'm fine. Um, what are you doing?" Amy asked out of curiosity.
"I just... AHH!" Jane couldn't think of an excuse. Instead scales were painfully pushing out from Jane's skin.
Amy stepped closer and closer to free her Mom and Jane's heart raced. "It's ok honey, really. DON'T LOOK BEHIND THERE!". It was too late as Amy moved the cabinet and she could see something was wrong with her Mom's legs. "Mom. What happened to you?"
Jane wriggled free from behind the cabinet and she was laying on her back turning into a mermaid in front of her daughter. "I can explain but whatever you do, do not tell anyone". At that moment, Jane's legs begun the final stage where the legs fuse to become one.
