Emily dried the last drop of water on her tail, and it slowly turned grew, the scales fading away. It split into two appendages, which then grew feet at the end, and returned to being her legs. Of course, she was naked from the waist down, but that was expected. She went over to mirror and took a look. Her hair was still the same strawberry blonde it had been before, and her breasts were still the same size, albeit without the sea shells, exposing her half-inch long nipples.
Emily pondered on a question in her mind. If she transformed with clothes on, would she lose them as they were destroyed, or would they be replace, and then come back? As she pondered this, she turned on the tap to wash her hands. She was quite naked still, as she enjoyed it. As her hands touched the water, her legs suddenly felt numb. Emily was confused. Then she fell over. Her legs were starting to fuse again!
Emily watched as her legs lost their feet, before merging into a single appendage. The purple scales popped up again, and her fins popped out again. The nipple covers flash back into place, and Emily sighed. "So the lady did lie. Not just saltwater-any water!" She grabbed a towel and dried her hand off, and her tail returned to being legs.
She soon found out that she was able to drink water normally, and that her clothes would disappear and return during her respective transformations, but if water got anywhere else, it would begin her transformation. She also found that, her breasts kept their "invisible bra state", causing her to never need a bra again, so it was helpful. Deciding that she wished to be able to get to the beach quickly, she returned to the store where she had bought the potion, and the lady was happy to sell her a special potion, which would allow her to teleport, whether it be to the ocean, or to a place which was safe should she find that her morph was starting. She drove home, happy with her decision.
Once she reached home, she sat down, drank it down, closed her eyes, and she focused on the beach. She heard a whomp, and then the sound of seagulls and things. She was inside a little cave, obviously not to far from public access, as hubbub from the sound of people talking was obvious. About 5 meters away, a pool of water was located. Peering in, Emily could see that it was quite deep, keeping her from getting beached. She could also see a part where the wall had sunken in, creating a tunnel to the outside world. Then she dived into the pool, her closes vanishing as she did so, leaving her naked in the water for the briefest second.
Then her legs began to fuse, her feet disappearing, becoming part of the twisting flesh of her legs. The purple scales rushed down like a wave, and her fins pushed out, her tails beginning to move instinctively to keep her afloat. The sea shell nipple covers flashed into their place, and her transformation was complete. Emily smiled and dived beneath the water, finding that, obviously, she could breathe and see underwater perfectly.
