Sea Salt- Mermaid tf tg

"Hello?" Eric called out into the empty house "Mom, are you home?" No reply came. He shrugged, letting his backpack fall to the floor with a muffled *thud*. He stepped into his house, flicking on the front hall lights. She must be staying late at the clinic, he thought.

Eric's mother worked at the local clinic, but ever since school had started, she had been staying late to finish up at work. Not that Eric minded, he enjoyed having the house to himself.

Eric groaned as he felt his tired shoulders ache, his football coach had been pushing him harder and harder, and he didn't think he could take it anymore. He was about to head to the basement to play video games until his mother came home, but he stopped and began walking up the stairs. If mom isn't home, the bath's all mine, he thought to himself. Arriving seconds later at the top of the stairs, he opened the door to his mother's bedroom, and continued into the large bathroom that was connected to it.

The tiled room looked normal enough, but the bathtub it contained was something different. About twice the length of a normal tub, and twice as deep, Eric's mother had had it installed when the house was being built. The tub was blue, and, at the bottom, a small amount of white sand lay at the bottom. The tub was made for salt water, as both reminded Eric's mother of her childhood in the Caribbean, and her heritage.

Eric turned on the warm water, watching as the liquid poured into the large tub, making the sand float around turning the water a mirky white. When the sand settled, Eric took a large box off the shelf labeled "Caribbean bathwater sea salt, soothing formula." And waited for it to mix in. Just to be sure, he dumped a little extra in. His mother probably wouldn't mind, and what she didn't know couldn't hurt her...

Eric stripped his clothes off and put them off to the side, sliding onto the deep bathtub. His muscles instantly felt better, the warm water felt good on his sore arms and legs. He leaned backwards, gently treading water.

The water felt so good, he closed his eyes and relaxed, feeling calmness wash over him. This was what he needed. His scalp tingled, like fingers were gently massaging his head, and stroking his hair. When he put his hands to his head, he couldn't feel anything different, it must just mean I'm relaxing, he thought to himself.

The strange tingling continued, and now felt like it was centering on his face, and neck, but Eric ignored it, it probably was just the salt water. The feeling began to cover his body slowly, continuing down his arms and chest like the feeling you get when you let the tide wash over your body at the beach. The tingling moved down his legs, finishing at his feet, leaving him feeling like his whole body was being tickled by hundreds of little fish, swimming past him. He still didn't open his eyes, afraid the good feeling would cease, so he kept them shut and let himself enjoy it.

The feeling suddenly intensified, ticklish, sharp, and stinging, all at once. It could've been the bath salt, he thought, he hoped she didn't have some sort of allergy.

But then, the feeling grew fiercer. The sensation of painful stinging grew as cold and sharp as knives, Causing Eric to give a yell. Now concerned, he opened his eyes. The hurting subsided, but as it did, his legs began to pull closer, causing Eric to gasp in pain. The skin between them grew hot, and began to meld together, starting at his hips and continuing downward, like his skin was melting.

He watched through eyes wide with shock, and his labored breath and heartbeat grew rough and ragged as he watched it slowly happen. Beneath the heat and ticklishness, he could just barely feel his legs' skin knit tight, merging them together as one. He could feel the muscles inside, twisting and sizing, blending and coupling together seamlessly under the shaping skin.

It felt good. Even through the pain it still felt like a warm massaging touch, as his legs changed. As much as he wanted it to be over, he couldn't help but feel like he was actually enjoying this bizarre occurrence.

"What's happening? W-what's it doing to my legs?"

Human leg bones to restructured into an extension of his spine, becoming more flexible than his human legs ever could of been...

Heel and ankle bones merged and twisted outward, toes lengthening, and growing as webbed skin grew between them, just like a fish tail. Scratch that, exactly like a fish tail.

"A fish tail? What the heck is this stuff..."
An extremely annoying itch, like a rash was spreading across his thighs, making him scratch irritatedly at it to make it stop
But instead of soft human flesh, his fingers met harder, smaller patches of something else, cold and hard like..."Fish scales?!"
Screamed as he felt them.

"A flippin' fish?! I'm turning into a fish?!"
Eric's panic was obvious, and he watched, shocked and in fear, as the scales spread.

The color was changing too, from Eric's pink skin color, to a light blue, to a sky blue. The color was spreading down his legs, itching terribly as they continued down her fused legs.

Strangely, the scales stopped as his waist, leaving him with a still human torso. Before he could make sense of this observation, a sudden pressure in his chest stopped him.

His nipples began to stiffen, areolas widening and growing. Small amounts of flesh began to push up under his pecs, stretching his skin as the small mounds grew.

"Oh no, no, no, no!" Eric said, panicking, as his chest grew larger and larger, now very obviously female breasts. Her face began to slim, her body becoming smaller and thinner. Another realization was that her hair was no longer short, falling long enough to even cover up her small breasts.

"Wait, I'm a mermaid?" Eric asked, looking at her tail, flicking water across the room with a single twitch of her tail. She stroked her long hair in wonder.
 
A sudden feeling in her throat choked her off, a feeling like she could no longer breath. She grabbed at her throat, trying to scream but found she could not manage any noise. A sudden pain, like gouges in her neck, caused her to thrash in the water in panic.

A few seconds later, she could breath normally, gasping as oxygen flooded her lungs. She ducked her head under water experimentally, and felt a pang of fear as she swallowed water unable to scream or breathe, but the new gills in her neck began filtering the water and providing her with fresh air, saving her from drowning.

She giggled as she dived under the water again.

------------------
Eric's mother had just returned from another long day at the animal clinic, a whole litter of puppies had come in and most of them had been sick. Opening the door, she tripped over Eric's backpack carelessly left in the middle of the hall.

"Eric, how many times have I told you not to leave your backpack in the middle of the hall?" There was no response, but she could hear laughing and splashing coming from upstairs.
"Eric, what's going on?"

She opened the door to her bathroom, only to see the last thing she had expected.
"Hey mom! I bet you're wondering about...this..." His mother somehow knew that this would be a long day...
