The sky wept, rivers boiled, mountains crumbled, and animals hid in fear. It could only mean one thing; it was Myu's birthday!

At least, those were the kinds of things Myu wanted to happen on her birthday. She awoke to the sound of birds chirping happily, and the sun right through her window and into the equine anthro horse's eyes. Myu opened up her emerald green eyes, and tossed the blanket over her head. She was definitely not a morning horse. She let out a sigh as she looked at her white hide hands with black nails and feathering. As much as the herm wanted to stay in bed, she had to get up and get things done.

Myu tossed the covers away from her, placed her hooves onto the hardwood floor, and stretched. She wore a purple shirt with purple and white striped pajama bottoms, silky enough to see her brown hide with white splotches underneath, and not doing that great of a job at hiding the massive set of cock and balls she possessed. Myu just casually stretched her arms up above her head, and with a wave of her hand, her coffee machine in her kitchen started up a brew of blueberry coffee. She made her way out to the hallway, down the stairs, and into her small kitchen. Myu had a modest farmhouse. She was a powerful sorceress, but she didn't need extreme luxuries to be happy.

Today though, on Myu's very birthday, she knew she needed something different. She let out a sigh as she looked around her home. Magic allowed her to do a lot of things, things people could only dream of, but even magic had limits on the things it could do. Once her coffee finished brewing, Myu helped herself to a cup, as well as cereal and milk.

Myu ate her food and drank her coffee, and she looked across her oval table to the empty chair in front of her. She gave a soft sigh, and leaned back in her own wooden chair. Her tail flickered slightly as she looked to a painting of a snow covered cabin. She didn't even remember where she got that painting.

"Every day it's the same thing, even on my birthday. Being evil is one thing, but fuck, this gets lonely." Myu felt her cock twitch, and her butt jiggle, and she just rolled her eyes. "You two don't even remember who you used to be. I can read your damn minds. Butt, you're just thinking about craping and farting, and cock? Well you want me to grab one of the farmhands and plow their asses all day long, which wouldn't be a bad thing, but there's no...I don't know."

Myu made her way to the door and opened it up to see her farm land. Her crops were growing in nicely, and she could make out various animal noises from her barn. She had plenty of farmhands to attend to the barn, but she knew they didn't care about her birthday. "I just...I need someone to share this day with. I've been working my ass off," she felt her butt shake. "No, I don't mean literally, but I've been working hard and what do I get? 
A farm, enough cunts, asses, and mouths to plow endlessly, plenty of money, but nobody to wish me fucking happy birthday or get me a cake without requiring me to hold my finger to their head and say 'do it or else!'

Myu walked out of her farmhouse. Her black hooves echoed as they stepped onto the wooden porch, and quietly faded once she made it onto the hard ground below. "I need someone that loves me for who I am, a lawful evil sorceress that does whatever the fuck I want."

Myu stared out onto the dirt road ahead. She lived a good hour away from any sort of civilization. "But the only one that can love me for who I am is someone who IS me." Myu smiled to herself as she got an idea. "Yes...that should work just nicely. The question is...who?"

Myu tapped her chin. "It has to be someone worthy, but not someone who wants it. A human will probably suffice, I'm thinking female...ah fuck it, it's my birthday, and I'm changing who I want to change." With a wave of her hand, Myu vanished from sight.

Myu reappeared in one of the many cities located across the world. She wasn't sure what city she was in, just it was one that spoke English. There were tall buildings everywhere, as well as people everywhere. Part of her thought it was New York, and it suited her needs. Nobody even seemed to bat an eye at her as she appeared from nowhere, now dressed in a kimono too.

Myu decided that the best way to celebrate her birthday wasn't by shopping, but by going to a museum. Finding a museum wasn't hard, nor was navigating the crowds of people. The museum itself had white walls that surrounded the exterior, and a stairway that led up it, and while there were people that littered the sidewalk like sand on a beach, the path to the museum entrance was just about empty. Myu paused at the staircase, and looked up at the glass doors. "Hm..." she turned around, and glanced at the many people that just kept passing by to the left and right.

"You'll do." Myu pointed to a woman with brown hair and fair skin. The woman had a pink shirt on with blue jeans and blue eyes. Myu didn't care about any other detail the woman had, just that she would suffice for her desires. With a flick of her wrist, the woman found herself walking right up to Myu, and with very wide frightened eyes.

"Yes I know, you're not in control of your body right now, I am." Myu spoke casually. She didn't care if anyone around her heard. In a populated environment, being casual was truly the best way to go about unnoticed. "It's my birthday, and I'm doing whatever kind of transformations I want. Now, I'm a simple girl, and I'm going to transform you in a simple way." Myu smiled at the woman, and gave her a deep kiss. She broke the kiss, and then snapped her fingers.

The woman was of course panicking, but when Myu kissed her, she felt as if Myu gave her something, something besides her wet saliva and hint of flat equine tongue. "W-what did you do to me?" Part of her wanted to scream, but she found herself unable to do so.

"Simple, I gave you a part of me." Myu traced a finger on the woman's neck, all the way down to where her heart was. "At least, somewhere in the...chest area, I never looked too much into it. Anyways, you're going to come to the museum with me. Some might call it a lame place to go for a birthday, but I like quiet places. I'm sure you do too, don't you?" Myu wrapped one arm around the woman.

The woman could pick up the scent of a barnyard that came from Myu. She wanted to be disgusted, but something in her told her to go along with Myu. The idea of going through a quiet museum suddenly didn't sound so bad. She also felt warm, and there was something else deep down she was feeling. "F-fuck..." she mumbled quietly.

"Yes, yes," Myu grabbed the woman's hand and led her through the glass doors into the quiet museum away from the massive crowds. "Of course we will be fucking too. For now though, let's enjoy a walk through history!" the entryway had a massive tyrannosaurus rex with multiple levels of viewing, as well as a place called 'walk through time' that allowed people to view history starting from the age of the dinosaurs, which was where they were currently in.

The woman didn't know why, but the very idea of sex with Myu, with this horse that just grabbed her was so...arousing? She rubbed her skin, and then looked down at her nails to see her fingernails had shortened and turned black. "M-my hands! My nails!"

Myu looked down at her nails casually. "Well, of course. They're still fully functional, but they're not ancient." Myu chuckled. "Look at these dinosaur fossils. How big you think their sexes were?" she teased.

The woman couldn't even give Myu her name. She looked up at the dinosaur fossils as they came into another room that had many more of those fossils, and she imagined how big their cocks were, how big their vaginas could have been. She hated how perverted her thoughts had become, and it made her lose focus on her hands. Her hands themselves looked paler, and she could see fine hairs appear from her wrists. "You're...you're doing something to me. I know you are." She whimpered. She wasn't even sure why she wasn't panicking more than she already was.

"Yes, let's see if you can figure it out before you're fully transformed." Myu gave her a peck on the cheek as the two moved on to the age of cavemen and Neanderthals. "Now, these have to look familiar to you, don't they?"

The lightning of the room, in fact most rooms were very dim. The lights overhead focused on the art and the creations while keeping the area where the people walked around darker. The museum was seemingly empty besides for the both of them, and nice and quiet too.

The woman looked at the large brute and burly men and women. She saw the excess hair on their legs, the look of dullness in their eyes. Sure the cavemen were nothing but figures on a display in a museum, but deep down, she had a strange memory of turning a woman into one once? It was devolution, something so rarely done, but done proudly, and then the sex afterwards was absolutely so much better than any human! The woman knew she had never done that though! She wasn't a magic user, nor was she an evil one. "W-what?" she could only look from the dummy, and then back to Myu. Her shoulders and the rest of her arms took on a dark brown look, a look that was slowly spreading throughout her torso, except for her belly which looked whiter.

"You remember it, I can tell you remember it." Myu stroked the woman's hair as a mane grew in, a mane just like Myu's in brown color. "Why don't we skip down a few generations and move to the part where they re-enact Salem?" Myu walked down with the woman a few hallways and into another room that had various artworks and dummies of the Salem witch trials. "This was such a weird time for us, don't you remember?"

The woman thought it was strange Myu spoke as if she lived in those times, but then again, the woman herself remembered living in those times suddenly. She remembered how Myu lived in Salem, and how she wasn't even afraid of being accused of being the witch she was because people were accusing each other left and right. Myu most never used magic on others back then either! People were just literally accusing each other just to blame each other. Myu wasn't responsible for the Salem witch trials, it was all people doing it to one another.

"You're remembering more and more about my life aren't you?" Myu hugged the woman, and felt the woman's breast slowly grow in size. She could feel her ass grow too, inch by inch.

"Y-your life?" the woman stammered. She rubbed her head, and crossed her eyes as she saw a white muzzle grow out. She could feel hairs grow on her neck and just where her shoulders were. She could also feel something else between her legs, something that made her cross her thighs and whimper. "You're turning me into you? What the hell did I do to deserve that?" she slowly realized what Myu had done, and she already had a bit of Myu's tone the moment she could tell what was happening.

"It's a gift." Myu slowly fondled the woman's breast from behind as they were still in the Salem exhibit. "You should be HAPPY you're becoming me. Well, not exactly me, and not part of me, but a lesser version of me is the second best thing I can turn anyone into. Now I have someone to share my birthday with!" Myu held the woman so close that her cock brushed against the woman's larger ass.

The woman moaned and pushed back against that cock. "N-no...I shouldn't..." her skin was covered in horse hide by now. Her body shifted a little bit here with pushing out, and pulled in there as bit by bit she changed to look more identical to Myu. She could feel her own cock grow in front of her cunt, and how it was already so erect and aroused. Her clothing felt so tight on her growing chest and ass, as well as her shaft, she wasn't sure how much longer she could keep wearing it.

"Come on, finish up your change, and give in to your growing Myu side." Myu's hands stroked her shoulders. "Just think of all the sex we can have. All you need to do is get rid of our clothes, and I KNOW you have the magic to do this."

The woman didn't want to admit that Myu was right. She could feel the magic flow through her body like blood in her veins. All it took was a simple thought, a desire, and a quick wave of her hand and their clothes vanished as if dust in the wind. It revealed their nude bodies, and just how much alike they were. The woman's skin was leathery horse hide. Her brown tail had grown in nicely, as did her mane. Her curves, her tits, her ass, even the cock she grew that wriggled inch by inch forward resembled Myu's.

Myu smiled at the woman. "Now, why don't you tell me your name?" Myu's white hide covered hands reached down, and gave the woman's butt a squeeze. 

The woman didn't even give her name to Myu, but there was only one name she could think of. She didn't remember even hearing Myu's name either, yet the name she thought of, she didn't want to say, if only because she knew the name in her mind had to have been wrong. The name in her head could not have been her real name.

"Come on." Myu rubbed her equine cock between the woman's ass cheeks. "Say your name loud, and say your name proud."

The woman let out a moan. She felt her body push back against Myu. By now, her changes had finished entirely. She looked identical to Myu, a twin carbon copy, even mentally she was gaining Myu's knowledge while losing her own, but there was one key thing the woman didn't have, Myu's dominant behavior. "I-it...it's Myu!" the woman cried out. "My name is Myu!"

Myu nodded to the woman. "Good girl. You look like me, you sound like me, and you even have my magic and libido! But there is one huge difference. I give cock, but you take cock." She hugged the Myu clone tightly. "Now...you know what I want. It IS our birthday after all."

The clone Myu nodded to the real Myu. She felt humiliated and embarrassed with what she wanted, and in the museum too. They had barely explored much of it, and already her anus and vagina felt so needy. She had a throbbing equine cock too, but Myu never let her use her cock on her. "F-fuck me everywhere you can think of. In and around every part of my body you can think of."

"Oh there are loooots of places fuckable on a body, places that most normal people, but I know you already know that." Myu continued to brush her cock on the clone's ass, up and down. "There's the feet, even though you have hooves just like me now, there's behind the knees, the armpits, stomach fat, hotdogging, hair, ears...god anywhere you can put a cock on a body you can probably fuck someone with it."

The clone Myu shivered as she nodded. She could only picture Myu's massive horse cock brushing up against all of those parts, and it was almost enough to make her orgasm. The woman that had come in with Myu was long gone, physically and mentally. The only thing left was the Myu clone, and the actual Myu.

 "But we'll start with the classics, and go from there." With that, Myu, and her Myu clone had one of the best birthdays Myu ever had.
