﻿Gadget hummed as he swiped his access card and went on his way to work. The red furred wolf liked his job at the detention facility, it gave him a sense of purpose by contributing to the safety of the kingdom. Making sure some of the worst Mobians were where they couldn’t hurt anyone. Of course there was always somebody causing a fuss but that was just part of the job to Gadget.  There had been a riot a week ago but Gadget had handled things so well that he had gotten promoted to east wing warden. 


As far as Gadget was concerned the biggest issue was Zero. Eggman’s last big gamble was his Project: Infinity, which had used the jackal mercenary and a stone with the ability to manipulate reality to destroy Sonic and then reconquer the world. If Sonic had gone alone that might even have worked. Infinite was able to conjure up phantom copies of Chaos, Shadow, Metal Sonic and even a champion of Dark Gaia to strike Sonic down. Except Silver, Manic, Gemerl and Sonia had gone with Sonic and made short work of the illusory foes before teaming up with the real Shadow to beat Infinite into the ground. It had been an extremely nasty fight and not long after that defeat Eggman just lost it and suffered a fatal aneurysm when he confronted Sonic. It took a bit of work but the power stone fused to the jackals body was removed and he went from Infinite to Zero. Gadget wasn’t sure if that was the jackal’s given name or just a moniker but it checked out. 

Zero was trouble, mostly because he knew how to organize. He was a better than average threat in the physical sense even without the Phantom Ruby. a master swordsman as the recently removed stitches to Gadget’s left torso, lower abdomen, back and tail would attest. Zero was durable too, the Hammer wispon that Gadget favored was by no means a weapon one just shrugged off. A good part of why Gadget had gotten so bloodied in the fight was his shock at Zero remaining standing after a blow to the head. Zero had to be struck with it more times than the entire cell block had put together. In the end both he and Zero needed an emergency transfusion of blood, several stitches and a course of pain killers. Zero was the riot's mastermind having orchestrated an escape, the disabling of several guards and even retrieved his personal saber from the lockup. Zero was presently in solitary confinement because his conspirators were vocally bitter about failing to escape and having their heads bashed in.


Gadget however was not about to have a normal day. Despite the best efforts of those in the know, packs of Futa virus tainted blood were still circulating. The riot at the prison meant that an inventory check looking for those tainted supplies had been interrupted and both Zero and Gadget had become infected by the blood. 


Per the usual neither of them had shown any symptoms on the first day and that made plenty of sense. Both of them had needed multiple bags of blood poured into them and only one each had the virus. Day two was the earliest it could have been detected by the speed with which both were recovering. Medical staff attributed this more to them being modified by Eggman and a hero of the Resistance respectively so it went unnoticed. Day three and four passed with nothing to mark the changes that were starting. Day five saw Gadget sexually examining his fellow guards male and female alike in the showers. By day six Infinite had taken to masturbating nearly every hour, his fantasies shifting between male and female partners by the hour. Today was day seven. Gadget had no clue just how he was about to change but his body was already preparing all that it would take was the right rush of hormones. All it needed was a rush of blood.


Gadget made it all of three feet from the entryway before a guardsman caught his attention.


“Warden, we have trouble in the solitary cells.” The hedgehog declared worry evident in his voice and expression. “It seems Zero is getting loud.” un said but obvious in the way the Hedgehog fidgeted was that no one else was willing to confront the jackal. Gadget sighed and gave a thumbs up before heading on to the solitary confinement wing.

Zero was in the cell and moaning loudly when Gadget arrived. The jackal had fully transformed the night before. Perhaps it was down to a more potent dose of tainted blood or perhaps a quirk of the modifications made to him by Eggman but Zero was in a state of sexual desire that defied conscious thought. Concepts like modesty, pride and especially propriety had flown out the window for the futafied jackal. As such Gadget was quite shocked by the sight that greeted him as he approached the transparent door to the private cell. Zero was on his knees pumping his shaft with one hand while the other was tucked around his back fingers pushing into his new pussy with machinelike fervor. The jackals' fur gleamed with sweat and the air around him was steamy. Zero’s breasts shook with the vigorous action of his self pleasure. The floor and door of the jackals' cell was streaked with globs of cum and a sizable puddle beneath the Jackals legs. 
Gadget was rocked back as the scent of the Jakals sexual desperation assaulted his nose. The jackal climaxed his cock going soft after a single spurt of thin watery seed.


Gadget’s vision swam as his heart hammered at the sight, sound and scent of utter desperation. Gadget's uniform groaned as the wolf’s own transformation kicked off. Thankfully the prison's uniforms were designed to be easily modified for a vast variety of body types. As Gadget's chest welled out into breasts to put his mother to shame the vest and shirt simply popped a few buttons open. As his hips spread out and his backside thickened the elastic waist band groaned in protest and his belt came undone at the clasp. The feeling of his erection pulling his underwear tight was how he felt the forming of his own pussy, the new lips rubbing against the fabric. The wolf huffed his breath hot enough to fog the air. The jackal watched his red eye fixed on the wolf’s groin where his arousal was plain for anyone to see. Wordlessly the jackal shifted, turning away from the door still on his knees and now one hand the jackal presented his rump and spread the lips of his drooling se the deep black lip glistening with his arousal and need. 


Under normal circumstances Gadget would never open the door to that cell without zero being sedated or with a score of other guards around. However Gadget was not thinking straight at the moment and so his card passed the reader and that door slid into the wall. Zero’s tail wagged, fanning the scent of his arousal further as Gadget stepped into the room. Gadget stripped himself naked with astonishing speed, his clothes somehow landing in the only corner of the room not covered in sexual juices. Gadget crossed the room in a step and a half the door shutting behind him as he grabbed Zero by the ankles. Despite appearances Gadget had remarkable upper body strength and so had no problem pulling the jackals backside against his hips. Gadget growled his efforts to fuck the jackal were frustrated by his cock sliding off her slick snatch instead of into it. The jackal cooed with delight at the feeling of a hot hard cock pressing against his needy entrance even if his present pose saw him face down on the floor with his tits swaying freely. Somewhere around the twentieth failed attempt to enter the jackal Gadget snarled letting on leg so he could guide his now dripping cock into her snatch. Gadget howled with delight as he grabbed the Jackal by the thigh and began to pump his shaft into him with abandon. Gadget grinned a fanged smile from ear to ear as he gave Zero a body shaking romp. The light in the room had shifted  by the time Gadget climaxed pumping his seed into the villain with four harsh thrusts.


Gadget sucked in lungfuls of air, his every breath sending  a new cloud of steam into the room. With a snarl and a howl the wolf shoved the jackal off him before pouncing atop Zero. Gadget grabbed the Jackals cock stroking it until it was once again hard the Jackal whimpered and tossed his head back overwhelemed by the pleasure of someone else touching his shaft. Gadget pinned the jackal to the ground with one hand as he adjusted Zero’s shaft and began to slide it into his own pussy. The Wolf’s breath caught as he adjusted to the feeling of being penetrated and to each inch that sank into his feminine sex. Each new movement, up down or even left and right set off sparks of delight through Gadget’s whole body. As the wolf shifted and hopped her breasts jiggled and shook  the weight, a new and welcome delight. Gadget gasped and moaned and howled like a beast as he indulged the desires of his new found feminine half. Gadget’s back stiffened as he came, his sex squeezing around Zero’s cock. The jackal wanted to cum but he had already spilled all the seed he could. Gadget however wasn’t going to accept that, he needed the jackal to cum inside him. The wolf pressed down harder on Zero who whimpered pitifully as his intense lusts were fading away. Gadget growled like a feral beast demanding satisfaction as he slammed his hips down onto Zero determined to wring an orgasm from the jackal. The light in the room got dimmer as the sunlight drooped lower and lower as the sun set the Jackal let out a cry as his cock spurted deep inside the wolf. The jackal almost immediately passed out.


Gadget huffed, rising from his partner finally in control of himself. The wolf took a moment to clean up and pull his uniform on and adjusted it to fit his new figure properly.  As he left the isolation cell behind it occurred to him he was starving.

“Sir?” Gadget turned to see a small crowd of guards clustered around the security station for the isolation wing. 


“Zero needs a medical exam and I need a heavy meal. Anyone else off shift can feel free to accompany me.” Gadget said before heading off and was delighted to hear more than one set of footsteps following after him.
