Elly has a tail

Today was the day. She had finally turned 20.

Which meant that today would be the day that she'd finally get a real tail and dump the simple clip-on that had adorned her outfits for the past three years. Elly couldn't wait.

She'd been staring in the mirror for almost half an hour now, picturing it between her ass cheeks, moving and looking like the real deal. A true tail on a real pet. Right now, though, she was still only staring at her bare ass in the mirrors reflection. Lifting her gaze, the rest of her bare body greeted her. She knew that she was a little plump. Not enough to actually be chubby, but enough to feel slightly self-conscious whenever she saw some of her thinner, athletic classmates in the changing rooms. That said, Elly thought that her weight suited her. It had certainly blessed her with a pair of larger, nicely shaped boobs that had been a source of jealousy for those thin girls she herself occasionally envied.

On her head, above her dirty blond tresses of hair, a pair of similarly colored fox ears animatedly moved to the faintest twitches of her head musculature. The way they unconsciously reacted to her mood was something she was really proud of. They were the one hallmark of a pet that she was allowed even before turning 20. Unlike tail plugs, which were reserved for adults above 20, there was no age restriction for movable ears. She'd gotten hers with 15, after a prolonged battle with her parents who had wanted her to wait until later before taking any steps towards pethood.

Since then, she'd gotten very good at manipulating her ears to the point that it really didn't take any conscious effort on her part. Still, without a tail to move in concert, she felt only half complete.

That would hopefully change at her birthday party later this evening.

Sighing, she turned away from the mirror and got dressed. Technically, now that she was 20, she no longer had to. Just like proper tails, public nudity was restricted to pet-dressing adults over 20 years old. Still, this wasn't the 1950 anymore, the age restriction for pet-dressing had been raised to 20 to better protect impressionable young adults and even pet-dressers didn't usually drop all clothes the minute they 'came of age'. More importantly, she wasn't even fully sure how much she wanted to commit to pethood. Plus, being naked in front of her parents sounded like a nightmare.

So, despite a brief moment of flushed hesitation, she dressed in her nicest summer dress and walked down to the living room. She was greeted by her parents and younger sister, moving about and finishing up the decorations. Balloons were scattered all about, some having 'happy birthday!', 'Dandy Twenty <3' or 'Happy pet-day!' written in golden letters. More decorations hung from the wall, and the table was fully set with a huge birthday cake in the middle of the table.

Elly smiled at the sight before walking over to her dad and hugging him. "Thank you so much!"

"Happy birthday!", he replied with a smile of his own. She let go and hugged her mother and sister as well, the two of them also wishing her a happy birthday. Elly helped finish up the decorations before the whole family sat down at the table.

The morning was reserved for a nice family celebration, while the main celebration with her friends was going to follow in the evening. But before that, Elly wanted to get her birthday present so she could get to the party wearing it.

After a round of singing Happy Birthday, the cake was cut and everyone went to enjoy it. Of course, her mom also decided it was the perfect moment to get out the present and tease her with it.

"Here it is~", she singsang, putting a long box wrapped in colorful wrapping paper on the table, but out of Elly's reach. Elly shook her head with a grin and rolled her eyes.

"You are enjoying this way too much, considering how much you argued against it."

Her mother shrugged. "Since I lost the fight, I might as well get some fun out of it." Unlike Elly, neither her mother nor her sister wore pet ears. She knew that her mom had experimented with pethood when she was younger, but had decided against it even before marrying her father. Unlike a large majority of married women, she didn't even wear a wedding collar, having opted for the archaic wedding ring instead. As a result, while neither was explicitly anti-pet, they hadn't exactly been supportive at any point in time.

For her sister, Emily, it had somewhat worked out. After a brief period at the beginning of puberty, when almost half of her female classmates had gotten ears, Elly's younger sister seemed to have gotten over any fascination with the lifestyle. Elly, on the other hand, had begged and argued until she got her way.

"Don't go overboard with it right away, though," her father said, rethreading an old discussion.

"Don't worry daaad.", Elly replied with a wry smile. "I'm not going to go full traditionalist just because I finally have a tail!" Ever since her parents had realized that there was no way to stop her from pet-dressing, they had instead focused on making sure she wasn't going to immediately hook up with some guy, make him her master, and become a full-time traditional pet girl.

"Good.", was all he said to that. And with that, her mom finally pushed the box towards her.

Naturally, she immediately grabbed it and went to tear away the wrapping paper. Once that was done, she opened the box and inside she saw it. Butterflies danced in her stomach as she took it in. Years of anticipation and want bubbling up as she lifted the tail out of the box.

It was long and bushy, the foxy fur colored in the same dirty blond tone as her hair and fox ears darkening in color towards the end until becoming fully black at the tip. It was the length of her entire stretched-out arm and so bushy that it was almost twice as wide.

"It's beautiful," she said happily. Looking up, she saw that her parents smiled proudly at her reaction. While they weren't a fan of her chosen aesthetic, they still wanted her to be happy.

"It better be, we didn't skimp on it!", her dad quipped. His words made her mom roll her eyes and nudge him, but Elly could see that both were glad that she liked it.

Focusing back on the tail in her hand, her eyes wandered to the other end of it. The end that was actually the important bit. Simple tail plugs were available as sex toys in normal sex stores, Elly had had one since the moment she had gotten access to one. However, they were just that, sex toys that people, who couldn't or didn't want to have a real tail, used to play pet in bed. No one would ever wear one outside.

And the difference was all in the plug. Unlike the sex toy variant, which had a simple buttplug attached to it, a true tail's plug was a complex bit of engineering. The mechanism had evolved and improved over centuries, but the basis had remained the same: segments that could be pushed to articulate the mechanism hidden inside the tail.

The one in her hand was made out of some black metal, the surface smooth and polished enough that she could barely see the lines of the different segments in its closed form. Gipping the base of the tail, she gently turned it counterwise, 'opening' the plug. The segments separated as the plug grew in width by about 30 percent before the mechanism locked again. Probing it with her finger, she could very easily push in specific segments, the action immediately triggering movement in the long articulated tail. She didn't know how, but even the smallest amount of **** exerted seemed to lead to big movements in the tail. Then again, she was studying economics, not physics or engineering.

Looking up again, she saw that the rest of her family was also studying the plug in her hand. Her parents seemed mostly curious about the way it worked. Emily, on the other hand... Elly was fairly sure that there was something else hidden under the fascination in the expression of her younger sister.

Oh well, she would figure it out herself.

Giddy and excited, she turned the opening mechanism clockwise again, closing the plug before jumping up from her chair. "I'll be back in a moment!" she called out while already making her way to the stairs. She could hear amused giggles as she took them two at a time.

Inside her room, she quickly shimmied out of her panties, leaving them on the floor as she bounced to the night table next to her bed to get out the lube stashed within. Obviously, she had practiced for this day. Aside from her old tail plug that she'd used a couple of times with her ex, the stories she'd heard about pet-dressers struggling with their new tails because they had never had anything up their butt before had motivated her to 'acquire' a set of training buttplugs even before being able to buy them herself.

Still, as she applied the lube to the new one in her hand, she couldn't help but feel a little intimidated. Even in its closed form, it was almost the same size as the largest plug she had. True tails were fairly heavy, and with their ability to move, they had to be held in place firmly lest they fall out. As a result, the 'opened' form of the plug was designed to be impossible to fall or pull out, both through shape and size.

While slightly apprehensive, there was no way Elly would chicken out at this point, so she resolved herself to be quick. In the closed configuration, the plug was narrow at its end, only widening into a bulb after two-thirds of its length. That made pushing it in a fairly painless, if tantalizing experience. Still, her previous 'training' and the copious amount of lube made it easy.

Opening the plug was a little scary and Elly was very, very slow as she gently turned the mechanism to expand it. That had the unintended side-effect of her acutely feeling how it slowly it expanded inside her. When it was fully open, she let out the breath of air she had held in her tension. It felt... full, but also secure.

Very carefully, she tugged on the tail, testing how well it held. The feeling was very strange, but there was absolutely no give, so after a moment, she stopped. Instead, she tried moving the tail. Even just a tiny clench immediately caused it to move to one side. Though having no real experience, the movement was clunky. No matter... it worked!

Elly squeeled a little as she tried out the clenching patterns she had learned from the internet and practiced on a normal plug. It felt awkward, and the movements were stiff and unnatural, but the tail did what she wanted it to do. With more time and a lot of practice, she knew that it would look more and more natural and in a couple of years, she would hopefully reach the point where it no longer took her any conscious thought for the tail to move as if it were part of her.

And even now it looked gorgeous!

Stepping in front of her standing mirror, she couldn't help but gawk at her reflection. From beneath her kneelength sundress, a beautiful blond fox tail emerged, lazily curling to one side. With a little effort, she managed to get it to sexily sway from side to side. God damn, she looked good like this.

She was tempted to fully undress and play pet for a bit, but her family was waiting. So instead, she quickly put on a new pair of panties before heading down again.

She was greeted by clapping and compliments, and while she knew her parents were mostly being polite it still felt great. Finally, she had a tail.
