"It's hereee! It's here, it's here, it's here!"

Tails grabbed the package and ran inside with excitement. It was addressed to him, Miles Prower, and that's how fast he felt his heart beating.

It was a small box, maybe a foot wide and long, and several inches deep, custom made and sent to him. It wasn't cheap and took several weeks of waiting. The fox dashed to his machine laboratory and pushed a button, locking the door behind him. "BUSY - DO NOT DISTURB" flashed a bold red sign above.

Tails' hands quivered with excitement as he opened the box, removing the wrapping paper and revealing a deep blue Zero Suit, made just for him. He was going to order the boy's style online, but looking at all the designs and options, he couldn't help but enjoy the idea of seeing the girls clothes on his own body: a lowcut pair of shorts and a mini shirt, more akin to a sports bra than anything else.

His hands caressed the cool latex finish, and as he did so, he felt a familiar warmth below.

"G-god, it's so nice," he said, inhaling deeply and briefly savoring the rubbery scent. "Fuck, I'm so glad Sonic isn't here right now..." he said to himself, turning on his various cameras and recorders. Once they were operational he gave them a cute wink, and started to strip his clothes off.

Or what he had for clothing, anyways. Shorts that were a little *too* short, panties that suited a little fag like him, and his traditional red shoes. They were kind of sweaty since he didn't have socks on, for better or worse. (Better for him, at least when he was in the mood for that sort of thing)

He looked down as his throbbing cock. It was fully erect, but still somewhat soft. He was immensely turned on by owning his own sexy outfit that he could wear all the time. He carressed the latex again, feeling it cling slightly as he rubbed against it. He continued this for a time, and eventually brought it against his cock and rubbed it too, drooling a warm amount of precum against it, his 6" of fox cock trembling.

"O-oh Mobius..." he whispered. If he wasn't careful, he was going to blow before he even put it on!

Instead, he smiled at the cameras again, and turned around, showing his tight rump to the machine. He bent over and carefully spread his cheeks apart for it to get a good shot for several seconds. His internet friends would love it!

Tails finally got to trying on the Zero Suit. He moaned slightly as the cool latex shirt squeezed his chest a little bit tighter, feeling his nipples touch the material with every movement. He felt himself throb hard, releasing another small amount of pre against his will. The shorts were easily put on as well, with no zippers or anything, just a one-size-fits-all arrangement. It clung to his body and squeezed his groin just as tight as his chest, if not more. His package and balls felt confined, sweaty, and tight, the same as his young fox ass.

Tails chewed on his lip at the sensation. It was unbearable, he was going to cum just from *wearing* the suit, never mind jerking off in it! His cock and sack were heavily bulging against the lower part of the outfit, a very clear outline of it struggling to burst free. He went to pull the front down so he could paw at himself but ... it stuck to him. The suit would not let Tails remove it.

"W-wha? I'm STUCK like this?!" he stammered in surprise, feeling the suit resist all his attempts to force it off. It wasn't fair! He was still aroused - almost painfully so - and had no way to get off. He fumbled at the front, feeling his cock, desperate to get off. His hands wrapped halfway around the bulge, awkwardly fumbling at it as he felt his orgasm build, and a disappointing climax come and go, leaking a sad amount of cum against his body and latex suit. It still clung to him.

But Tails felt ... something. His nipples stiffened and felt warm. He went to touch them, to itch or scratch them, anything. He found two small lumps on his chest, as the suit squeezed and kneaded his torso, almost with a mind of its own, as breasts started to form. "W-what IS this thing?" he said, aroused and confused as the suit took over. He didn't realize it, but his cum activated its secondary, gender-changing properties.

As his breasts began to fill out, he started to pant, sweating from arousal. It was hot in his room after all, and the tight latex and physical activity didn't help things! Tails felt a rippling sensation around his loins and lower half. He felt his cock stretch and grow within its rubber prison, snaking upwards to be 8 inches long, erect again, and oozing pre as it went. His balls felt like they had doubled in size, while his ass cheeks began to match the size of his breasts. The suit managed to contain it all, but looked rather large in comparison to his otherwise normal frame.

Tails' legs quivered as he orgasmed again, suddenly! He dropped to his knees and felt at his cock, twitching and spraying cum, as he orgasmed a second time within seconds! The suit was pushing his entire body into overtime, in a good way. As he laid there quivering on the floor, a sweaty, cum-filled mess, the suit continued to squeeze and press and expand and alter his young body. His ass cheeks grew out to the size of watermelons, big enough to easily smother another animal's face. His tits grew outwards to rival Rouge's, and in moments, surpassed them. His cock was up to 10 inches, 14 inches, and saw no sign of stopping. The suit strained to keep it all contained.

Tails managed to recover his breath, meekly regaining his senses, still overwhelmed by the Zero Suit's ability. He noticed the cameras were still recording, and smiled again, distantly, and slowly inched his way closer to it, his legs still quivering from the multiple orgams and his hand constantly groping at his new thick package.

"D..." he panted, trying to find words. "D-do you like what you see..?" he asked the camera, inches from it, trying to position his sack next to it so it could get a good view. The suit kept straining, and eventually the tip of his cockhead poked out. He admired his drooling fat mushroom looking up at him, 18, no, 20 inches of throbbing, hard foxmeat, as thick as his own thigh and much longer. He traced a finger around the puffy urethra, already gaping from the growth and ejaculations, feeling himself shiver at the stimulation. He leaned over and easily locked lips with the hungry entrance.

He cooed and almost yelled from the pleasure as his tongue lashed out against the inside of his urethral passage, being rewarded with a generous spurt of pre and remnants of cum. His foreskin, peeled back, began to slide back over his hood. He helped it along, the stretchy skin rolling over his jawline and nose.

Tails inhaled deeply.

Tails inhaled deeply, and for several seconds, lost in the scent of his own cockmusk. He continued to pump his shaft as best as he could, still breathing from his musky cock hood, as another orgasm shot up his pipe and into his mouth. He greedily gulped it, the sticky cum down his throat. He nursed his cockhead as much as he could until his churning balls felt empty, greedily slurping down what he could and making a sticky mess otherwise. He let out a small belch and giggled weakly. He was feeling exhausted!

But still, the Zero Suit continued to work his body, his balls churning and rapidly producing more cum than he could release, swelling up again, larger this time. They were each the size of his head, his cock 26 inches and almost as wide as his torso now. Straining at the shorts, he could see the stitching barely keeping the latex together as his monster overwhelmed it.

Tails cooed as he released himself from his cock. He reached up and felt his breasts again. They were each a foot wide and very heavy. His nipples were larger too, the base widening in proprortion, and the nubs grown to be as big as his thumb. He propped one into his mouth and sucked on it like a child, fingering the other nipple's opening with his free hand, his dick distantly twitching and throbbing from every motion. It continued to leak into his shorts and around his body as he pleasured himself to another countless orgasm.

He was nearly passive and overwhelmed, sore from the pleasure; out of energy, yet no desire to ever stop. Tails smiled at the camera again as he slid his cockhead between his huge breasts, the tip spreading them apart as he locked lips with it again, his fingers assaulting his nipples as they too, began to drool their own fluids.

Tails gradually came two more times in this position, always smiling and laughing at the camera, but eventually drifting off to sleep, as the Zero Suit occasionally continued to rumble and make certain parts of anatomy bigger still.
