They mutate her into a monster!

Once her initial despair passed, Teysa decided to at least try to explore the cave. The monster did not appear to care if she swam around-- its bulk blocked the only exit, but she could swim freely inside. The cave was about the size of a castle gatehouse, and filled with odd scraps and ends of treasure. Silky seaweed and colorful anemones clung to the walls. Looking at them made Teysa feel... hungry. Odd. Her rational mind dismissed it as a symptom of stress, but just looking at the anemones made her stomach growl. The growling didn't stop when she looked away, though. Instead, it built, and she felt her guts gurgling. She abruptly bent as far in half as she could, clutching her stomach with both hands. The roiling nausea was so bad she thought she might throw up. Just when she felt she could hold it in no more, it abruptly faded. Inside, she felt something squirm.

There it was again. There was no question-- something was moving inside her. She looked down and could see small bumps pressing against her stomach from the inside. The eggs in her womb were moving-- they must be hatching. Terror seized Teysa. She had heard of people being eaten from the inside out by hideous grub infestations. Was that what was happening to her? Tiny stabs of pain jetted through her. She moaned, releasing a stream of bubbles, and clutched her stomach with both hands. Shortly, she felt the wriggling and the short jabs inside her ass as well. Whatever the eggs were doing hurt! And nothing appeared to be coming out. She spread her legs and desperately pulled her pussy lips apart, trying to make it easier for whatever was inside her to get out without having to chew through her, but nothing seemed to come. The short stabs became more frequent, more insistent. Looking down, Teysa could see shapes wriggling just under her skin. They were about two inches long and as big around as her finger-- worms of some kind. She realized they must have passed through her womb somehow; they were just under her skin in places. They spread out, along her limbs, all around her ample breasts, even up her neck into her head. She clawed at her skin frantically, mad with terror. Oddly, however, there was no pain.

Suddenly her arms didn't seem interested in following her commands. She felt woozy. Something must be happening to her vision-- her arm thrashing in the water no longer appeared to be straight, but waved like a strand of seaweed. She looked down and her legs were the same way. It wasn't an optical illusion-- her limbs bent bonelessly. She tried to snap her head around to look and instead it lolled like a doll's. She opened her mouth to scream and her teeth floated away gently. Something catastrophic was happening to her body. Before her eyes, her legs shortened, knees disappearing. At the same time, her toes were lengthening, curling away from her like ribbons. Like tentacles, in fact. Her arms were the same way-- her elbows no longer appeared to divide forearm from upper arm, while her fingers elongated into thin tendrils. The fat was being redistributed across her body, especially into her breasts and her growing tentacles. Her hair fell out, and a frond of thin anemone-like tendrils sprouted in its place. Her captor noticed what was happening, and without a word it swam away from the cave. Seizing her chance, weeping in panic, Teysa swam for the door. In her terror she didn't notice the speed and sureness with which her altered body cut through the water. Still, the change went on. She shot for the shore like an arrow and reached it in seconds, pulling herself desperately onto land. She could still breathe fresh air, at least.

Waves of pain and nausea rolled through her. She spasmed and rolled on the cold stone floor until they finally receded. When the last had gone, she turned to the surface of the lake. Her vision had improved again-- she could see as clearly as if the sun were in the sky. Looking into her reflection, she felt dizzy and light headed. This had to be a dream.

Her skin was now a smooth, dark navy blue. Her face looked human, but for her bright green eyes, with oddly slitted pupils. She had no ears, and instead of hair she had a mane of thin white tendrils cascading down her shoulders. She found that she could move them with a thought-- they were prehensile, and incredibly sensitive. Her body was short and compact, and dotted with scales. She had enormous, dark breasts and pointed nipples the color of coal, each leaking a tiny amount of blue fluid. Her limbs were short and stocky, and each terminated where the hand or foot would have been in a mass of tentacles. She found that these were holding her up; she didn't appear to have any bones, but the tentacles were pure muscle and incredibly strong and flexible. They were about three feet long, but by concentrating she discovered she could extend them by almost half their length. She reached out and touched herself-- her skin was semi-translucent, she discovered, and very soft. It had the texture of gelatin. She poked a finger-tentacle into her stomach and encountered no resistance. The tentacles were tough muscle, but the rest of her appeared to be a gooey gel-like material. She withdrew it hurriedly and her stomach sprang back into shape. Her pussy was still where she expected it to be, and seemed mostly unchanged, though the slightest caress from her tentacles was enough to set it off twitching and quivering. She was much more sensitive now, it seemed. She tried to move about and found that she could flow easily along the cave floor, moving surprisingly quickly by pulling herself along with her tentacles.

She realized faintly, at the back of her mind, that she was an abomination. A monster, a cursed thing: her church would never accept her. She would be killed on sight. Oddly, the thought didn't seem to bother her. That was something to worry about later. She had to get away from this lake, had to find somewhere to hole up.

Besides, she was ravenous.
