Something I idled in the midst of my struggles of late.

The concept of female tails has fascinated (and yes, excited me :D) since I was a cub, and during browsing a load of Tailsko art I managed to find I just sort of formed a small story in my head.

I know this idea has been done a lot, probably better, but it was just a bit of fun so quiet in the peanut gallery. :P


A young, twin tailed fox sat in almost complete darkness, his beautiful blue eyes just staring into a darkened corner of his room. Miles Tails Prower, otherwise known as Tails the Fox, was in a world of inner turmoil.

After saving the planet finally from Dr Eggman, the Freedom Fighters had tried moving onto a normal life, which for anyone having fought a tyrannical dictator for years was difficult enough. Tails however was only 8 years old at the time the fight for freedom started, one of the youngest of Sonic's group. Now 16 years of age, reality had not been kind for the young kitsune. He had been too young to start his own job at the time and so Sonic encouraged him into joining college...to which all his efforts seemed forgotten. Socially shy around those his age had made him an open target for bullies, and that was before taking in his looks. Instead of becoming more bulked up he was mistaken more than a few times for a female for his slender build, beautiful eyes and thick twin tailed plumage.

Sonic at the time had tried his best to help his troubled buddy out, but there had only been so much he could do. Then came the day he finally Married Princess Sally Acorn and became very tied up with duties as a member of the royal family meaning he had very little time to spend with him any more.

His bare, furred hands clenched tight at the last memories of college, of guys dressing him up in stolen female gear and bullying him to prance around like a vixen. Worst of all he had enjoyed looking beautiful when he caught his reflection in the gleam of a locker.

He'd fled there and then, still in a cheerleaders outfit much to the laughter of most of the college before shutting himself in his small house and refused to talk to anyone.

Tightening his hand, digging his short claws into the palm of his hand until they bled into his soft fur, he stood up with a determined expression and reached for his phone.

Dialling for the acorn residence, the phone rang a few times before switching to the automated answer phone. Taking a deep breath, he spoke into the mouth piece. "Sonic...Sally...and everyone else," he started in as even a voice as he could manage, "I'm sorry, but this is goodbye. Things have not worked out since we saved Mobius from Eggman, honestly I question what we were really fighting for. As things go I need to leave, I'm sorry but I can't say where or if you'll ever see me again, but I need to move on and go somewhere for a fresh start. Goodbye."

Hanging up the receiver, he heaved a deep sigh. He knew they would be upset but it was better than him just up and vanishing. With a determined surge to his feet, the lithe kitsune marched on over to a connecting door to his little workshop. Upon entering, he hit the lights on and whipped a canvas off of a machine in one corner consisting of a glass chamber over a platform, a computer controlled feed back and a container fitted to the side of the platform.

Turning the power on the computer screen flickered into life and the machine hummed as it powered up. He had built this to change his appearance, to make a fresh start. But the complications and risks were so high with gene altering that he wimped out and abandoned the idea. But now he knew he had no choice, he was going to be Miles the kick around no longer. He would alter his fur colour, his build and features of perish in the attempt.

Typing a few run sequences into the computer, he stripped any clothing off, leaving him in just the fur before sliding a section open with the flat of his hand end entered the glass chamber.

Stepping inside, the door closed automatically and micro scanners roved his form, sending feedback to the machine of his build.

"Okay..." Tails said with a moments hesitation before giving the voice command, "run sequence!" With a hum the machine fired up. A green mist started filling the vessel up from the container, a little something he had developed in Biology. It would destabilise his anatomy enough for the scanners to perform the double function of reconstructing his mass from the blueprint he had coded into the machine. A side project he'd secretly worked on in his final days in college that he had stored on a storage device.

The solution had a numbing, paralysing effect as he had expected with destabilising his anatomy, but he had a vague sensation of his body slowly taking shape. But suddenly the computer blared out, "WARNING: FOREIGN OBJECT DETECTED."

Tails tried to open his mouth to give the command to terminate but the mist had robbed him of voice as well. All he could do was wait with cold dread for the process to finish.

The mist evaporated, and he found mobility return to his limbs. Placing his hands against the plastic sides, he shakily staggered to his feet as feeling returned to his numb limbs.

Sliding the door open, he took a shaky step out of the chamber before feeling something foreign on his chest. Looking down every-so-slowly, a high, feminine shriek ripped from his throat. Hanging proud and threatening to overtake Rouge's assets protruded from his chest fur a pair of round, full soft breasts, the pink nipples hard against the air.

"Fuck no! No! No! No!" He shrieked over and over, shaking his head only to find another new addition flap around. Dashing to his computer he punched up the front view camera to look at his form. Instead of a vision of male masculinity, what stared back was a beautiful vixen. She was tall, lithe with a light ginger, almost golden coloured fur coat. His tails were larger, looking like each could comfortably be used as a duvet. The large set of breasts jiggled with each deep breath, threatening to overtake Rouge's assets. His head was now more feminine, sporting softer angles and longer eyelashes that complimented the long thick golden fringe he now sported.

His heart pounded in his chest as he also noticed he had a pussy in place of his penis. Tails hands became a flurry of activity as he looked through the program. The schematic was the same as always, designed to change his form into a butch male, tall and with a darker coat. "How could it have gone so wrong?" he said in a husky, female whisper before an internal view of the machine showed up something a little off in the canister of the machine.

Trying to dash off towards the machine, he almost lost his balance due to his new assets swinging freely before taking things slower. Opening the now empty canister, he saw to his dismay a single strand of fur stuck inside the tin container. Picking it up, he wondered how it had come to be in there before his eyes flew open as he remembered.

The day he ran out of college he'd finished working on his formula when a pretty vixen happened upon him. "Hey tails, what you doing? That really doesn't look like what we were asked to work on in biology."

"Leave me alone okay?"

"Hmph, whatever loser. I'm reporting you to the principle for dangerous use." She had then turned around and whacked his face with her large bushy tail as an insult.

"So...that must have been it..." Tails sighed and slumped to the floor. "The broad build must have mutated into having these...large assets instead."

Sighing softly, she slumped to the floor and onto her toned rear. In an effort to vanish and become more masculine he was now what everyone kept calling him. A girl.

After checking through his options, Tails concluded that to try and change back now would not only be risky, but would most certainly end in his/her demise. Wrapping her slender arms around herself, she shivered and buried her head in arms. The poor twin tailed kitsune was unsure how to feel. Deep down she knew she enjoyed the sight...but...could this really work out? Would he actually be able to live like this, with what he had always been mocked for?

Tails lost track of time, of how long she sat there on the verge of crying. The body felt so alien and yet...something felt right about this. Eventually she grew tired of self pity eventually and uncurled from the cold, hardwood floor.

Looking over the new form again in the computer screen, Tails sighed softly, realising she didn't have the right attire to cover his new female body up. Punching a few orders in for an online clothing catalogue, the near golden furred kitsune bought a few items she hoped would fit, only having a vague idea of women's size measurements.

With that done, nature called for her to answer, and soon found that the female body could not hold it the same as the male body could as she only just made it in time to the bathroom. But it was then that she found the pleasures of the female system.

During a tentative wipe of her new slit, Tails hand came into contact with a fleshy nub that shot a spike of pleasure through her body. "Ohh that...that felt good," she moaned softly before pausing. Her voice when she moaned...it sounded really erotic when she moaned in pleasure. With her excitement building up in anticipation and body starting to tingle, Tails quickly washed her hands before rushing off to her bedroom before slamming the door shut and sitting on the edge of the bed.

"That...felt so good. I wonder..." she trailed off before deciding to go for it. Sliding a finger into her young slit, she gave a sharp intake of breath as her finger found the clit, but this time she kept on rubbing. "Oh...oh this...is what a female feels during sex?" Tails said in a breathy moan before her other hand brushed along her generous chest. Her hand paused in its exploration of her clit at the sensation, "Its so soft...and warm," she said softly, her baby blue eyes widening as her hand pressed and felt around the soft, warm fleshy mound.

Hesitating over a perky pink nipple, the twin tailed vixen pinched gently, eyes closing and head leaning to one side at the pleasurable feeling. "Ohh...I can see why females can get addicted to sex," she moaned softly before her hands took on a life of their own, pinching, rubbing and teasing her, the finger buried in her pussy plunging deeper and braver the more she got into it.

"Ahh, haah, oh...what is this feeling? I-it feels...so different to when I masturbated. I think I'm...Ahhhhh!" she cried out shrilly, her huge tails twisting together as she climaxed and rained her female cum down on her sheets, creating quite the wet patch before slumping back, her chest heaving and breathless.

"Wow...just, w-wow," she panted after a while of laying, finally regaining the strength to talk. "That's what it feels like...to have a female orgasam?" she said softly, the white tufts on her face glowing pink in a blush before she finally managed to sit up. Raising a wet paw to her mouth the vixen gave a tentative lick, finding the taste appealing which only caused her face to heat up even more. "I think...I might reconsider my options here," she said with her hand on her heart, a peaceful expression on her face.

Two days later and a blue blur shot by, a speedy purple chameleon not far behind him as they raced to Tails house. Sonic had been that busy it had been two days before he even thought to check the answer phone. Soon as he heard of his buddy's note, he had got hold of Espio in case his ninja skills would be useful to track him down.

Stopping by the front door, he pounded hard on the wooden panel. "Come on Tails buddy, don't do this. Not after everything we have been through. You can't just up and vanish on us!" he said, his foot tapping rapidly before trying the door again.

"Um Sonic? Maybe we could try the open garage?" Espio said calmly, pointing towards the large door by the side that was open almost in invitation.

Face palming himself for overlooking such an obvious detail, he chalked it up to his worry. "Tails, are you still here?" Sonic said, looking around at the various machines around the shop.

A twin pair of tails, slightly blackened from dirts stuck out from beneath what Sonic recognised as Tails beloved Tornado...or it had been but now it seemed a bit more refined somehow. "One minute," a soft, female voice sounded from under it, taking Sonic aback.

"Tails? What happened to your voice?" He said before he rolled out from under the plane, causing Sonic to jump back in surprise.

"Oh Sorry, my brother isn't here," a pretty vixen smiled from beneath the grime, clad in a chequered red and white female working vest and short jeans that accented her hips and toned legs.

"Er, hi," Espio said in a slightly chocked voice, seeing the way her breasts seemed to fit only tightly inside the confines of her clothing before clearing his throat. "Er I d-don't suppose you'd mind answering a few questio"

"Where's Tails and why do you look similar?!" Sonic said, pushing him aside and cutting straight to the point, leaving one disgruntled chameleon.

"Oh well, to be honest I don't know really. I got a call from my brother a few days ago asking me to come and keep things going and to get to meet his friends. He said he wanted to say goodbye, but he didn't know if he'd be able to make the move then. He told me to tell you all not to worry about him, he is fine and safe and knows things will be better with the changes."

The pair stared on at her before looking at each other and nodded. "So you're Tail's sister then?" Sonic said slowly, trying to keep his eyes on her face and not anywhere else.

Her soft giggle only made it harder not to blush in her presence as she used a wipe to remove some grime from her body, letting them get a good glimpse of how pure her fur seemed underneath and white the breasts were between her cleavage. "Yes that's right, I'm...Melissa. Melissa Prower, nice to meet his friends, I hope we can become close friends," she smiled at them.

She noticed Sonic's glum expression and put a hand on his shoulder. "Did I say something wrong?" she asked softly.

"Just...all this time I never even knew, none for us knew Tails had a sister. There is no denying the resemblance but...why did he keep secrets?"

Espio saved her the trouble of explaining thankfully. "I am sure he had his reasons, we all know he has been going through a lot. Maybe one day we will get the chance to hear from him, but for now we should try and make her feel welcome."

Melissa looked his way and batted her eyelids at him in thanks, making the chameleon's face turn crimson. "I'm sure you'll know when the time comes, but don't worry about him okay Sonic?"

Raising his head, the blue hedgehog almost ended up with his face in her cleavage before taking a hasty step back from her. "Y-yeah, well um, welcome to Knothole. We'll invite you to the rest in time but I think my wife er, needs me. Later," he said, shooting off to avoid any more awkwardness.

"it was very nice er, missing you, I mean meeting you Miss Prower," Espio said falteringly, having hardly stopped blushing in her presence as he made to leave too. But to his surprise she grabbed his arm in her hand before sliding it down his strong arm, letting her soft fingers linger along his own hand before letting go.

"See you around Espio," she said softly, the poor creatures face almost looking it was going to burn up as he tried to answer with a dry mouth before shooting off.

Sighing, placing her hand on her heart, she had been fantasizing not of Sonic, but of Espio. She had always found him cool but once she was a girl, it had quickly evolved into something akin to love for him. And that voice...that deep voice.

"See you around," she said softly with a hand on her heart, her tails whirling around gently behind her. "I think life will get very interesting from here on."
