David is a fairly average african-american male of 44 years of age. He was browsing the Internet for assorted things and tripped over a site with furry art that ranged from adorable to quite raunchy. He figured he might have an interesting experience trying out one of those "interactive story" things, something he'd never tried before. He decided to try the one called "TF Nightmare" because it had some sexy pictures and he figured it'd lead to an interesting experience.

He was wrong. Very wrong, but not in the way he expected. The story started off fairly promising, with him being drawn into the world of the thing, but his adventure took a strange turn when his character somehow ended up turning into an attractive female rat-person. His avatar, which had started out looking like a stylized version of himself, now had a feminine body and a rat's head, complete with whiskers. To David's shock, as soon as this happened he suddenly felt very strange, as a tingling sensation ran over him from the top down, focusing on the end of his spine and the tips of his fingers.

A chill ran through his backside. He felt his backbone stretching and writhed, then sat still, shocked. He looked at his fingers and saw his fingernails and cuticles turning black and elongating into claws. His spine tingled again, and this time he felt his butt get heavier, and then fuller, fleshier.

He got out a gasp, but it sounded cracked and changing.

He felt something soft brush his legs and reached a hand up to his lip. Something touched his fingertips. A long, thin, sensitive whisker, with two more on either side. He opened his mouth and ran his tongue across his teeth. They were flat in the front and growing steadily. "What the heck is going on?" he said, and was shocked at how high his voice was becoming.

He heard a knock behind him and turned around. "Hey, is everything all right?" came his mother's voice, sounding far lower than usual, and he gasped in shock, his chest feeling larger and heavier. "Everything's fine," he called out, hoping his mother wouldn't notice the changes.

His mother left, and David looked back to the computer, shocked and scared. His skin had turned a dull gray color, and his nose and mouth felt strange. He reached up and felt, and sure enough, his nose was extending and merging with his upper lip, his jaws getting longer and thinner.

His chest was getting heavier, and he glanced down, seeing his nipples darken and turn brown, his chest swelling outward into a pair of huge, heavy breasts, each one the size of a basketball at least. He looked at the monitor, and sure enough, his avatar was turning more feminine, growing a shapely pair of breasts and wide hips, with thick thighs. He felt his own hips and thighs getting wider and fuller, and his spine tingled again as his tailbone began to grow outward.

A thick, fleshy, furry pole emerged from his jeans and extended, the fabric ripping at the seat, and he felt his hair curling and extending, a few inches at a time. He saw his forearms and hands turning black, and felt his ears twitching. He reached up and touched his ears. Each sent shocks of new sensations as they danced against the touches. He, er, she was a rat lady. She was a furry.

And the worst part was, she had loved every moment of it. She laughed, hysteric and confused, but bouncing from foot to foot with an almost crazed smile. "Look at me."

She looked herself over. A long black tail hung from the back of her jeans, now ripped open at the seat. Her breasts were larger, and her feet were much different. Her toes and fingernails were now long, sharp black claws. She was a rat, wait, no. Rats didn't have fur on their tails, right? She grabbed and stroked along its furry length.

That's nice, she thought to herself, stroking her own tail. She was still thinking in a female way. She couldn't stop herself. Not that she minded terribly. "Diseased human to buxom mouse lady? I'm taking it."

She looked at the screen and read on, seeing what would happen next. She could feel her body itching as she grew taller and more powerful. Her muscles swelled up to match her growing frame. "I better stop this." She closed the tab. "I like what happened. Don't need that changing."

She stood, her muscles rippling as her legs and torso extended. The floor was a lot farther away than she remembered, and her pants and underwear were in danger of falling down. She unzipped her pants and slid them off, then stepped out of the legs and kicked the whole bundle to the side. "I am looking good." And feeling it, all the various aches of age and disease, banished.

She looked at herself in her room mirror. The reflection showed a tall, muscular, feminine mouse. She looked at her own breasts. They were huge, each one the size of a basketball, firm and proud. She smiled at them and reached up to give them a squeeze. "Eh." It was fat, not some magical thing. She laughed at her silly assumption and turned to the computer. "Now—"

Before she could do much more than touch her computer's mouse, it all went to hell again. She was no longer in her room, but a dungeon. It was the dungeon she had been in, in the game. She looked around, and there was a door, just a few yards off. "This is going to suck, I just know it." She went to the door and found a note attached to it, with her name on the front. She opened and read it:

Dear David, you're not in your world anymore. You are trapped in my world, and there is no escape. This world is a world of transformation, where everything can change. You will never be the same. Fight well and fight hard, the strongest get to keep their forms, so long as they keep winning, and don't do anything foolish.

-Management

David blinked, then read it again. She shook her head and crumpled the note, tossing it aside. "Bullshit." The door ahead was closed, and she had no key. She grabbed the handle and tried giving it a great heave with her new, powerful, arm. The door rattled in its frame and she felt the wood give a bit. Another tug and the door swung open, leaving a large, splintered chunk of it hanging onto the handle.

David stared for a moment, then shrugged. "Well, I guess that works."

She stepped through the doorway, finding herself in a large, dark room, the only light from the torch. She could hear the sound of running water and the distant sound of voices. She could smell food, and could feel the presence of others. "Hello?" she called out, and heard the voices grow quiet. "Is anyone here?" she called out again, and this time, there were no voices, just the sound of water, and the occasional rustle of fabric or the clink of metal.

She grit her teeth, worrying about what was waiting for her as she cautiously stepped forward into the darkness. Her rodent eyes seemed more capable of seeing in the dark than her old human ones. Her eyes adapted quickly, and soon she could make out the rough outlines of the room. The floor was smooth stone, the walls were rough-hewn, and the ceiling was high. The air was cool, and the room was damp.

The room had a few doors, one at each end of the room. She walked to the nearest door and tried the handle. The door was locked. She sighed and moved to the next door, and found that it was locked as well. Approaching the last one, she found it unlocked, and stepped inside.

The room was small and dark, and a figure sat on the bed. It was a young girl, about ten years old. She had long hair, brown, with a slight wave to it, and wore a simple dress. David started with surprise. "Hello there. This is a dangerous place for a little one like you to be."

The girl looked up, and David could see that she had brown eyes, a nose and mouth that were not exactly beautiful, but pretty in their own way. She smiled. "Hi. I'm Sally, and I'm a prisoner of the monster that rules this dungeon."

David quirked an ear at that. "Monster? What monster?"

Sally pointed toward the ceiling. "It is a great, big, horrible beast. It is covered in scales, and has a long, thick, forked tongue." She shivered. "It is the worst thing you could imagine, and it wants me to become a monster like it."

David frowned at the description. That sounded very much like the kind of monster that'd be in that game. "I won't let that happen. Hum, by any chance, do you have a weapon hiding around here?"

Sally nodded and moved to a small, wooden chest. She opened it, and David saw a large, wicked-looking dagger. "Yes. The monster left it here, and I'm afraid it will use it to try and hurt us."

David took the dagger and tried a few slashes in the air. "Alright. I'm going to go hunting. You stay here and safe until I get back, okay?"

Sally looked worried. "But the monster-"

David waved her off. "It won't be a problem. I'll be back soon."

David turned to leave, but Sally stopped her.

"Wait! Take this." She held out a necklace with a glass pendant. "It's a magic item, it can save your life. If you wear it, the monster won't be able to hurt you."

David looked at the pendant. It was shaped like a heart, with a small, silver chain. "It's nice." She put it around her own neck and it dropped right between her breasts. "Figures." She rolled her eyes with a chuckle. "I'm even cuter now."

She left the room and approached the first door she had found locked. She put her hand on the handle and tried to open it, but the door held fast. She grunted and pulled harder, and the door finally gave way.

Inside was a large room. The walls and the floor glinted with clear moisture. There was no light, except for that which came through the door, but it was enough to see the room was circular, and empty except for a large, black, oily shape that lay in the middle.

The shape rose with a gurgling noise, rushing to attack David. David slashed at it with her dagger. A spray of black fluid splattered across her fur. The creature roared and reared back, and David went for a quick stab and the monster screamed. Feeling confident, David pressed his advantage, slashing at the monster wildly, cutting deep into the thing's flesh.

The monster was cut to pieces, and collapsed, twitching. David was breathing heavily, and her fur was soaked in the black ichor. She shook her head. "Ew, that's gross." She wiped the dagger on the thing's carcass and sheathed it in her belt.

She looked at the corpse, and shuddered. She'd killed it.

A sudden sharp tingle ran through her where she'd been splattered, the black gunk flowing over her, becoming a leather outfit that hugged her body in all the right places. "Hm." She looked at her outfit in a nearby reflective surface, posing and turning this way and that, and nodded. "Not bad, not bad at all. I bet I'd turn heads in this."

She walked back to the cell and saw Sally sitting on her bed. "No troubles in here? There was a monster, but I'm guessing that wasn't the boss."

She shook her head. "You defeated the creature?" she asked. "But, that's impossible. That creature was the strongest. It was a servant of the master."

David smirked. "Maybe I'm a bit tougher than I look. Or there's another monster. I don't know. Either way, I'm going to get you out of here."

Sally smiled. "Thank you."

"Stay safe. I'll be back." David left the room and went to the next door, finding that it was locked. Seeing as it had served her well so far, she pulled it powerfully and the door opened with a loud crack.
