Sally’s legs suddenly hive out underneath her and she falls to the floor unplugging the Phone in the process. She tries to stand up but her legs just won’t hold her anymore and she falls back down again. In fact she can’t feel either of them anymore!
Her Legs are stuck together heel to heel, ankle to ankle, calf to calf, knee to knee, thigh to thigh and she can’t pull them apart.
Sally can only watch as they begin to press against each other harder and harder. She lies on her side (as the dorsal fin prevents her from lying on her back) and sobs in pain and fear. She begs it to stop as she watches her feet start to flatten out and grow into a fin. She feels the bones in her legs dissolve as her legs quite literally start to melt together! It starts at her feet or rather fin but it continues up with her calves merging together and then her thighs and before long her legs are now one long tail. The White skin on the inside of her legs now formed into a solid racing stripe. Her vagina shifts upwards to the front of her tail and she feels her spine extend down filling up her tail. Sally flops the limb watching it move in a way impossible for her old legs could do.
Sally just wanted Ointment for her sore feet. Now she was a Shark Mermaid in the middle of her living room, her long blond hair spilling out on the floor, her tail curled up around her defensively and her eyes full of tears.
