Tails TF story


He wandered through the house trying to not make a single sound, each footfall only making the floorboards creak ever so softly. In fact the young vulpine’s eyes bounced from one shadow to the next as he slowly drew nearer to his destination. Thankfully it being the dead of night meant that so far everything was going well. His twin tails twitching every so often to correct his balance, providing that little bit extra stability. On more than one occasion his ears perked up hearing a slightly more sensitive board creaking, which allowed him to avoid disaster. Finally he reached his target, that being a simple wooden door. Now the door itself isn’t a problem as the genius that he is slides out a set of lock picks from the fluff of his tails. The picks themselves having been secured with a rubber band to prevent them from coming loose, are soon taken up into his dexterous paws. Picking through the lock is child’s play as in mere moments there is the satisfying click of the lock opening up. A rush of heat passes through him, one tail moving to cover up his now bulging boxers. The reason for this sudden rush of arousal becoming obvious as he silently opens the door, for inside rests his dear “Aunt” (the memory of which makes his bulge twitch all the more Sally. Now whilst she could easily be his mother at her age, time has only served to render her even more beautiful to Tails. Yet his gaze only lingers on her for a few moments as instead he sees the true target of his, that being her wardrobe. Shutting the door he almost seems to glide along the now carpeted floor, each footstep muffled rendering each step far more confidence. Opening the wardrobe doors without a sound he takes a moment to be thankful for his vulpine night vision, as whilst things are darker then what he would like, that doesn’t mean he cannot drink in the sight before him. As Sally’s entire selection of clothes are laid out before him, mostly shorts, a couple sets of black boots and more simple clothing. 


Yet none of that is his goal as tucked away in a corner is a small black box, which he gingerly takes up in shaking paws. The reason for these nerves becomes obvious as when the lid slides off  it reveals Sally’s old button up jacket. Its soft blue colours are only slightly muted due to the passage of time though for Tails it couldn’t be more perfect. Taking the jacket out of the box he quickly slides it over his bare chest, the clothing fitting snuggly to his trimmed frame. Now a soft smile forms as he runs a paw over it moaning quietly to himself, not caring at all that Sally is a mere eight feet from his position. His jeans bulging out all the more as the other paw reaches dow not gently squeeze his bulge. Eyes closed in mounting pleasure he lets out a single huffed word of pleasure as a sudden rush of heat washes over him.


“Sally.”

Opening his eyes back up he turns around now drinking in the sight of his dear Auntie. With the warm summer heat she is dressed in a silk panties and matching bra. The material is designed for comfort instead of modesty with the rest of her body barely being covered by the duvet. Another much stronger surge of heat makes Tails stagger for a moment, paws rushing to his head in surprise to steady himself. Leaning forwards just a bit his rump presses against the cool glass of the mirror nearby. The sharp contrast his rear flex even through the confines of his clothes, taking one step forwards he catches himself instead of fully face planting. Standing upright he doesn’t even notice the slight tightness down there, instead wiggling his hips trying to get them a little more loose. Yet if anything that feeling of constriction is only growing worse but Tails ignores it for the moment. Whatever it is he can think about it later as his lusts are already chipping away at his reasoning. This is a plan months in the offing, he sees no reason to not indulge every little urge. Another tingle flows through him and looking down this time with narrowed eyes as he could have sworn a soft creaking sound filled the air. Almost like something being stretched out, yet hearing and seeing nothing wrong in the dim light he shrugs it off once more. The mirror however reveals the truth as there is a definite curve to his lower half now as flesh is slowly inch by inch piling on, the jeans growing taught and snug. Not letting anymore weird things distract him Tails moves to start buttoning up the jacket. Each button sends a wave of memories rushing through his mind, a dreamy smile starting to form as he recalls all the adventures they used to have, all the battles fought and won. All the times he admired and revelled in just how snug Sally’s clothing is, how it amplifies her curves into something that would make most green with envy and burn with lust. The daydreaming only grows more intense as the heat from before rushes up to his chest. Narrowing his eyes in pleasure as the final button is done up the image of Sally standing before him grinning coyly, her chest pushing out the jacket as normal. Yet this state of affairs quickly changes as it starts to swell outwards, inches pushing it outwards as her bust starts to swell beyond even the most maternal of women’s chests. The creaking sound of the jacket desperately trying to hold in the amount of material grows louder by the moment, as now seams are starting to pop open. The sound echoing like a gunshot in his mind, as with trembling paws he gently starts to squeeze Sally’s breasts. A proper moan escapes him this time, rational thought running to the hills as the Sally image moans back at him. Her shirt is utterly stuffed to bursting, each shaking breathe threatening to have the entire garment explode off her chest. Yet Tails now realises that he has somehow gotten himself turned around and is looking directly into the mirror. He isn’t seeing Sally swelling up before him, instead its himself or rather herself given the figure her body is developing rapidly. Breasts the size of her head spill out of a jacket on the verge of destruction, hips flaring outwards help hold a pair of jeans aloft that at this point should have fallen apart. All of this of course only helps amplify the twin swells of her booty, the sudden jolt of surprise making it wobble like jelly. Just barely stopping from letting out a loud squeak of awed wonder Tails takes a moment to try and get stock of the situation. Somehow by some means she is swelling up into a vixen with curves that at this rate would easily put Sally to shame. Rather than feel worry, shame or fear at this, instead there is a bone deep sense of rightness to this, that this is exactly what she deserves in this moment. Indeed if at any point in the future regret and logic overrides feelings, Tails knows she can just change it all back. So for now she chooses to ride out the waves of pleasure that rocket through her body, setting the mind ablaze with a new type of need. One that is only growing stronger as the jeans and jacket grow tighter by the moment. Yet this time its because of thickening thighs, which lose none of their athletic poise or grace even as they are swelling with a soft cushy layer of fat. Her den is already dripping with a mounting need thanks to whatever strange twist of fate has made her like this. 


Putting a finger into her muzzle she gently bites down on it to avoid waking Sally up with her moans, everything is starting to feel so very hot as the young fox is turning into something out of her wildest dreams. Those dreams of course bine about sally at first but now shifting entirely towards what she can and is becoming. That being the object of years of desire, need and want all wrapped up into one delicious swelling package. Both paws reaches up to heft her still swelling breasts, which must easily be past E cups. The jacket growing to have more and more tears within it, as the seams are now starting to pop open, allowing warm fur and squishy flesh to spill though the gaps. Those jeans of hers aren’t fairing any better as her lower half seems locked in a battle to find out who will burst out of what confines first. Tails cannot control the changes and doesn’t want to either as her brain is starting to drown in a sea of chemical bliss. Eyes closing for a moment silently willing herself to keep growing, that request being one her body is all too happy to oblige. The popping sounds of before give way to full on tearing at this point as patches of the material gives way, falling to the floor. Biting down all the harder Tails still lets out a muffled howl of need, her den only growing wetter as those thick thighs of hers grind together with one another. The front of the jacket is on its final legs, as each hurried breathe pulls more and more of it apart. Of course the rear won’t be denied its advances either as it too is trying to beat out the bust for first place. The bliss of it all is already pushing the surprised vixen into a state of heated need, as her paws sink into the front and rear of her body willing it to keep growing. Now she starts to openly hump the air, forehead pressed against the glass not caring at all for volume or discretion. She simply feels far too good to care about it, not to mention she won’t stop for anything at this point. So she humps moaning harder with each second as the moment of eruption grows closer, the fabric on both sides is on its final legs as it simply cannot hold back the tide of expanding, soft, fluffy flesh. Closing her eyes fully Tails surrenders herself to the mounting need howling through gritted teeth as with a sound akin to paper tearing her clothes finally fall to the floor in tatters.


Huffing, panting and whinging softly she takes a few long moments trying to get her head in order. Yet such thoughts are quickly robbed as she feels a firm spank to her booty, which not only makes it wobble like shook jelly but also send her into another screaming orgasm. This time however when her eyes open, she sees Sally standing fully naked grinning form ear to ear. Her words triumphant and horny in equal means, as her eyes scan Tails from head to toe before nodding once in approval.

“I was wondering when you would work up the courage. Now why don’t we have some real fun eh?”

Tails doesn’t need to be told twice as the two pounce each other, falling onto the bed to enjoy a night of pleasure neither of them will forget for as long as they live.
