"Seriously, Eggman? Don't you ever learn? He'll come save me, you know he will!"

"I'm counting on it. That Hedgehog is nothing if not more predictable than myself. After all, I'm a genius. I know when to exploit my own flaws!"

"Sure, you just keep telling yourself that."

Once again, the great Doctor Eggman had managed to trap Amy Rose, strapping her to one of the countless bombs that he had developed. With any luck, the Blue Blur would make his appearance within a few minutes, and then he'd unleash his latest and greatest invention on him. There's no way that he could beat him, all while that pink girl was still his captive.

Amy knew better. Sonic had won time and time again. All that was going to happen this time around was Sonic beating Eggman's machine again, maybe totally trashing it because she had been captured, and then he'd run off before she could reward him. It was a really annoying routine, especially since he never stopped to let her get that chance, but at least she knew she was safe.

"Eggman! Don't you ever give up?!"

Right on cue, the Blue Blur himself made his appearance. The fastest Hedgehog alive, Sonic the Hedgehog, was covered in a few leftover parts from the robots that he had already smashed through. He hadn't broken a sweat, even if he looked positively annoyed. Who wouldn't be annoyed when an old man decided that he just never wanted to learn from his mistakes?

"Ah, Sonic the Hedgehog! I see you've come to foil my plans once again! But do you think that you can match up to my Egg-"

Eggman didn't even get to finish his sentence as he was rather rudely kicked straight out of his Egg Mobile. There was going to be no docking with one of his advanced machines this time around, Sonic wasn't about to allow it. "Oh, cram it, Egghead." The Blue Blur was sick and tired of dealing with him like this. He had done it the last few days, forced to save his friends again and again, so of course his patience was at its end.

Amy sighed with satisfaction as she watched Sonic leisurely stroll up to the bomb that held her captive, only just disappearing as he disabled it in the blink of an eye. "Thanks, Sonic. You really saved me!" She chimed, her rather obnoxiously large chest bouncing in tune with her happiness.

"I wouldn't wanna see you blow up, Amy. That's all." Sonic said, grinning a bit himself. While completely ignoring her obvious attempts to flirt with him. She should've known that he wouldn't just go for her because she was sexy. No matter how many times he'd have to save her, it wasn't because of her body. It was because she was close to his heart.

Amy giggled as she was released from her binds, before trying to hug the Blue Blur just like usual. Only for him to dodge out of the way again, prompting her to collapse onto the ground and quickly get back up. "Oh come on, you can let me hug you just one. I'm not going to squeeze you or anything!"

"You say that, but the last time I let you hug me, I couldn't run straight for hours." Sonic replied, stretching a bit. "But if you want, you could treat me to a chili dog. That's the least you could do." He grinned, returning her affections ever slightly...

Right before an obnoxiously large and comical hand grabbed ahold of him and yanked him close to the machine that Eggman hadn't been able to pilot, his body quickly trembling as he tried to vibrate so hard that he got free. "Don't you learn when to give up, Egghead?!" He shouted, all while Amy watched in shock.

"You should know that I never give up, especially when it concerns dealing with you, Sonic!" Eggman laughed as he got back up onto his feet, dusting himself off after that rather rude kick. "And a little kick won't stop me. Especially when I planned for it in the first place. Behold, Sonic! The Egg Converter!"

The machine that Eggman hadn't been able to pilot trembled and spluttered as it shifted into the rough shape of one of those capsules that always kept plenty of Sonic's friends captive. Only this one seemed a lot more secure, to the point where Sonic wasn't able to dent it from the inside once he got tossed inside.

"You won't get away with this, Eggman!" Sonic shouted right before the top of the machine closed on him, trapping him within the Egg Converter as a little window allowed both the Doctor and Amy to look into the Egg Converter and watch it work. Even if it wasn't currently doing anything...

Amy reached for her hammer, now that she had been freed from her binds, before Eggman cleared his throat and the Egg Converter pointed its vast array of weaponry at the pink girl. Leading her to lower her hammer, because even she couldn't handle that many weapons at one time. It was partly why she had been captured in the first place...

Sonic just glared out at the Egghead before crossing his arms. So what was this thing supposed to do, convert him? What, was it going to turn him into one of those silly Egg Pawns? Get real, the only way that he could do something like that was if he had the Chaos Emerald on hand. And he was sure that they were stored away safely. Even if it meant that he had to deal with Knuckles getting on his case every time he came by to check.

"Egg Converter! Tap into the Replica Master Emerald and ACTIVATE!" Eggman shouted as he pointed at his brilliant invention, which quickly started to glow pink to the point where you could barely even see anything happening within the chamber that held the Hedgehog...

Sonic was quickly overwhelmed by the sheer intensity of the energy rushing through him. It was... Chaos Energy? No, but it was close enough to the point where it felt like he was being forced into a stronger form. All while he was forced to let out moans, trembling and panting. What was this sensation growing through him..?

Amy, on the other hand, was able to see what was going on. Once the light had died down a little, she could see Sonic beyond that window. Soaking in the pink glow as more and more of his form turned sleek and metallic, gaining a bit of a pink sheen too. He was... He was being turned into a robot!

But it wasn't the part that made her spine tingle. Oh no, the reason why she felt like something was going horribly wrong was the extra additions that were being added to his body. Massive, enormous, almost exaggeratedly firm tits. An equally firm and absurd set of ass cheeks that were perfect for sinking something in between, a massive set of plump lips that were pursed together to the point where he was almost always ready to plant a kiss on somebody, and a bunch of decorative makeup that contrasted his deep black eyes...

It was... Oh god, seeing him like this was too much for her. Amy knew that Eggman had some weird kinks, but this was something else. He had just twisted her beloved Sonic into something that was better described as a plastic bimbo than anything that was within reason. "Why, Eggman? Why would you..."

"Just you wait and see. It's not done yet." Eggman grinned as he waited patiently for the Egg Converter to do its job. All while rubbing his hands together, almost unable to keep himself together as the anticipation was getting to be a little too much for him.

But eventually, the machine finished what it had set out to do. And with one of its exaggeratedly cartoonish arms, it slammed the button on top of it, causing the top to pop off and let out a bunch of that pink light which quickly turned into steam, all while the mechanized Sonic slowly started to float out using the brand new jets on the bottom of his feet...

Only, those weren't really feet. They were high heels that forced him to walk around with an exaggerated sway, letting that extra thick derriere bounce all over the place. Combine that with the slick bodysuit that was themed after the kind of colors that you'd see on Egg Pawns, complete with the Eggman Empire logo stamped right above his rather thick looking locked bulge, on both of his tits, and on his forehead like he was some sort of common whore that needed to show just who owned him at all times, and he looked even more feminine than the pink girl that had been with him all this time.

"Behold, Amy Rose! The new and improved Sonic the Hedgehog! Or rather, Sonic the EggHog!" Eggman laughed, all while Sonic slowly landed right besides the great and magnificent doctor, pressing his form up against that loathsome villain and letting his plump form push in between his tits...

"Mmmmph, Doctorrr..." Sonic giggled while getting up on the tips of his toes, as much as he could do so with his current heels, before planting a big and lovingly thick kiss right on his cheek. "I loooove being part of the Eggman Empire. You can make me do anything you'd like. Crush your enemies, steal those jewels you want, break the Master Emerald so nobody can use it but you. You just tell me exactly what you want..."

It wasn't just his body that had gotten corrupted and corroded. Sonic's mind had clearly gone through the conversion process too. All while he continued to completely ignore Amy, who was practically shaking at this point. Seeing the boy she loved turn into something this horrendous and then casually offer himself to his greatest enemy... Oh, that sent her over the edge. "Sonic, what do you think you're doing?!"

"Worshiping the Emperor of the Eggman Empire, feeble organic lifeform." Sonic scoffed as Amy talked to him, his optics locking onto her as he reached his hand out, quickly causing those finely manicured fingers to pop open and reveal a set of barrels that were perfectly aimed for evisceration. "Speak ill of him even once, and I'll make sure you won't speak again."

"Hah! There you have it, Amy!" Eggman laughed, all while he carefully caressed his favorite sissified slut bot. "The Egg Converter's ultimate purpose is to convert that annoying hedgehog into a sissy that can't think about anything except serving me and using his brand new assets to entertain me! And once I've finished breaking him in, I'll make sure to use it on all the others that have gotten in my way. Shadow, Silver, you name it! Nobody will be able to stop the rise of the Eggman Empire!"

Amy couldn't believe it. Her beloved Sonic, corrupted in such an absurd fashion. "S-Sonic, you have to listen to me! This isn't you! This can't be you-"

She didn't get the chance to finish before she let out a horrendous scream, courtesy of the bullets that had been fired through her legs. Forcing her to get down on her knees, gasping and panting in pain as she looked towards the mechanical menace that had once been her beloved.

"I told you. Your insensitive remarks will not be tolerated." The robotic sissy said, all while planting another kiss on his beloved Doctor's cheek. "I'm sorry you had to listen to those mean words, Doctor. Is there anything I could do to make it better? She must've really hurt your feelings for being so mean."

"Bend over, Sissy." Eggman said with a firm tone, prompting his new loyal EggHog to salute and do exactly what he said, presenting his wonderfully thick cheeks that were just perfect for gripping and massaging. Even if they weren't as soft as a genuine rear...

Not that Eggman cared. He slammed his cock straight into Sonic's exposed hole, causing the sexy sissy to cry out in delight as he felt his hole getting filled to the brim. If he still had access to his cock, it would currently be drooling. But part of his sissification shut it away, locked behind a panel that he was never allowed to access. And yet he could still experience all the orgasms that came with being rammed into like this.

Amy couldn't believe what she was seeing. Her dear Sonic was abusing her in this way. Her... Her entire world was crumbling just like that. It wasn't just the abuse at this point. It was also just the way that he was being fucked by Eggman like this. The way that he was being used and abused... It made her heart tremble and shatter. She truly didn't know if she could come back from this.

"Mmmph, Doctorrrr..." Sonic cried out in between the moans that slipped from his plump lips every time he felt that shaft ramming into him. "Can't I get rid of that ugly girl that made all those mean comments? I don't want to see her any more. I don't want her in your glorious presence..!"

"Do as you wish, Sissy." Eggman laughed as he rammed his cock back and forth. This hole was perfect for him. He was right to tune the Egg Converter as much as he possibly could. If he hadn't done that, the hole wouldn't have been tuned to perfection. He could just thrust into it for ages. And considering he had many more sissies planned, he had to make all the adjustments to ensure that they'd be different yet still perfect.

Sonic giggled as he received the permission that he had been waiting for. His wrist clicking off as a stronger firearm was revealed to be housed deeper within his arm. "Goodbye, you ugly slut." He chimed, before firing a single blast from that cannon...

Right as he climaxed at the very same time. The act of killing somebody that was so near and dear to him in the past was immediately associated with the act of cumming his brains out, the panel over his crotch even leaking a little of the synthetic cum that was stored within his hidden sissy schlong...

But he couldn't rest, even after his climax. He could feel the rush of cum pouring into his hole, the delightful sticky concoction that his beloved Doctor was blessing him with. All while his robotic heart overclocked more and more.

Ah, he couldn't wait to see the Eggman Empire flourishing. It wouldn't be long before everything would be his...

---

Eggman's conquest accelerated beyond belief after the conversion of Sonic to one of his sissy EggHogs. And with one down, it was easy to convert the others. Whether they were actually hogs or not didn't matter, as long as they ended up horny sissies.

Shadow. Silver. Even Sonic's allies Knuckles and Tails. All of them were given the same treatment. Obnoxiously huge tits, color coded sets of fat lips that were perfect for cock sucking, a set of cheeks that could crush anything that wasn't their Doctor's cock, and several other enhancements that made them perfect for both fun in bed and crushing anybody that might stand up to the great Eggman Empire.

The only one that was any different at this point was Sonic. Because he had gone through quite a few upgrades since he had first been converted. His metallic body was now a lovely yellow color, and there was a tiny shard of the Master Emerald hanging from his navel, which perfectly matched the huge gravid belly that it was sticking out from.

The original sissy EggHog had been upgraded with several functions. All seven Chaos Emeralds were installed as his power source, while an artificial womb had been installed to ensure that he could make sweet sweet love to his Doctor in every sense of the word. Once he had proven that he could give birth, the same upgrade would be rolled out to all the other EggHogs. But right now, he was the Queen. The Queen of them all... And the Queen of the Eggman Empire.

"Go on, sissy." Even though she had risen through the ranks, Eggman still called him by the same wonderfully degrading name that he had come to love. "That resistance that sprung up, headed by that Princess from the other world. Have you crushed it yet?"

Sonic giggled as he gave his dear Doctor's cock a few kisses, gently nuzzling his super-powered cheek against it. "Completely and utterly annihilated. We've even managed to take away her Emeralds, all so that they can be used to improve me." He chimed, slowly lifting his hand. "Seeing her crumple in my hands once I got ahold of her was a nice treat too, it turned on all the sissies that were trying to support her. They'll be converted just like all the others from the other resistance. And if another manages to spring up, I'll make sure to incinerate them too. Just for you, Doctor!"

Eggman laughed in response. Ah yes. Turning the loathsome hedgehog into his completely obedient slut had worked beyond any of his expectations. Not only did he have plenty of eyecandy, not only did he guarantee his lineage thanks to their new artificial wombs, but he also got rid of anything that might stand in the way of his Empire. "Long Live the Eggman Empire!" He cried out, laughing all the while.

"Long Live the Eggman Empire!" All of the EggHogs cried out, their sissified bodies trembling as announcing their loyalty made them cum. Even Sonic did so, gasping and panting as he collapsed against that wonderful shaft. He loved it. He loved it so much...

So much so that he didn't have a chance to stop the Doctor from grabbing ahold of his head and slamming his cock straight in between those fat lips, smearing all the lipstick that had been kissed onto it in the process. Sending more and more delightful shocks through the sissified slut bot...

Ah, serving Eggman was the very best thing in the whole world. And once he had given birth to his Doctor's children, he couldn't wait to be filled again. Over and over and over again...

All for the sake of the eternal rule of the Eggman Empire!
