It was a typical battle with Dr. Eggman. He was on the attack at Angel Island again, and it was up to Sonic to put a stop to it. Having chased Eggman to his makeshift base in a cavern of Red Mountain, he now stood face to face with the doctor's latest machine. Eggman was safely behind an electrified barrier, and a laser device was hooked up to the roof high enough that Sonic couldn't reach it. "Well, this looks familiar. And now, you're gonna shoot that thing at me until your equipment overheats and your barrier shuts down, and you waddle away just fast enough to find a convenient escape hatch." Sonic said, having seen this sort of setup before. "I see you have a very good memory when it comes to my... design failures..." Eggman said disgruntledly, "However, you're wrong when you think I will be shooting at you. I know better than to think I can hit you." he smirked. Just then, a hatch in the floor opened, and a capsule holding a strange magenta energy sphere emerged. "I've been mining this region for rare samples. Behold, the Ero Sphere! Hidden among the Blue and Red spheres you once encountered here on Angel Island. Now... I will obliterate it." he said. Sonic wasn't sure what he could, or should do as Eggman's laser opened fire on the container. He had no idea what this "Ero Sphere" was, but as the laser struck the container, the Sphere shattered, and the energy contained within flew out in several directions! The barrier in front of Eggman protected him from the energy, but it seemed intent on finding a living body to enter, and that seemed to mean Sonic! Not knowing what was happening, Sonic didn't try to run until it was much too late, and the energy of the Ero Sphere flew into him, coursing its way through his body! Eggman laughed victoriously as he watched what would become of Sonic. The sphere's energy caused Sonic's body to undergo changes rapidly. He felt himself quiver as his figure seemed to become slimmer. He felt something stir on his chest, two somethings beginning to grow, and he felt a stirring between his legs. When he went to feel it, he shivered as he felt something wet! Eggman continued laughing hysterically as the light around Sonic's body faded, and Sonic began to see why as he caught "his" reflection in the remains of glass from the capsule the Ero Sphere was contained in. The energy from the sphere had somehow transformed Sonic, changing him into a female hedgehog! "Oh, Sonic! Aren't you looking lovely!" Eggman laughed, pleased with himself. Sonic glared at him. "All right, ya sick perv! Change me back right now!" she shouted, cupping her hands over her mouth as she noticed a slight change in the pitch of her voice. Eggman tried to stop chuckling as he deactivated the barrier between them. "But Sonic, my dear, I destroyed the only sample of Ero Sphere I know about. I have no way of changing you back." he said, "You must be tired. You'll be comfy... if the dungeon." Eggman sneered. Sonic frowned and gave Eggman a swift knee to the crotch as he approached her! "All this just to screw with me! Jerk!" she growled, running off for the exit, though a bit slower than usual. Eggman stumbled over and groaned pitifully. "C-call me... Errr... I mean... I'll get that hedgehog!!"

As she made her way out of the mountain, Sonic wondered what to do now. Conventional wisdom told her to seek out Tails for help, but she figured she better be careful who sees her as a HER. Especially buck naked. Sonic shivered as she felt truly naked for the first time. There had to be a way to change back. But could she discover it on her own? As she was making her way along the cliffs on the exterior of Red Mountain, she felt like she was being watched. Maybe she was just jumpy. Or maybe Eggman was chasing her? She looked around cautiously. "Boy... Bolting for the exit of the mountains wore me down... Did the change do something to my running stamina, too?" she murmured to herself, wishing she had it in her to just dash outta there. Up on top of one of the many peaks jutting out over the area was a familiar red echidna, Knuckles, who had just climbed up there to get a look around. He was well aware Eggman had wandered onto Angel Island, and he was intent on finding out why. "Heeeere, Eggman... Where are you....?" he muttered, gazing over the area intently. He caught sight of a familiar set of blue spikes heading along a cliff, heading away from his direction. "Well, looks like Sonic... Did he always have such a cute ass...!? I mean... God, I hope no one heard that..." Knuckles muttered to himself, not fully comprehending the change to Sonic's figure from so far away and from behind. Figuring Sonic would have a lead on Eggman, he jumped into a glide and started towards the blue hedgehog. Sonic was peering cautiously around a corner of the mountain when she heard him land behind her. She stood up with a start and gulped nervously. "Shit, is it Eggman already?" she murmured. Now close enough to get a better look, Knuckles stared in puzzlement at Sonic's feminine new figure. His expression then changed to awe as Sonic turned to face whoever was behind her! Knuckles looked from Sonic's gorgeous new breasts, down to her flower, and up to the unmistakable face of his friend, which was staring back at him with a look of fear mixed with humiliation. "Augh!! Kn-knuckles!! I almost with it WERE Eggman!" Sonic gasped. Knuckles had a little trouble comprehending what he was seeing at first. "S-sonic...? That... really you...?" he wondered. Sonic tried to walk away. "Um... No. You're confused. Later, Knuckles." she said, only to have her arm tugged by Knuckles as he squinted at her. "You ARE Sonic! But... how!?" he stammered. Sonic, though embarrassed, was relieved that Knuckles didn't seem to be teasing her about this. "W-well... I don't really get it... But it's something Eggman did... that sicko." she explained. Knuckles looked over Sonic's new feminine body again and blushed a little. Whatever Eggman did, it looked pretty sweet. He found himself smirking a little. "So, Sonic, for once in your life, YOU'RE the damsel in distress in need of some help, eh?" he chuckled. Sonic pulled out of his grip and blushed brightly, growling at him. "It's not funny! It could just as easily have been you, it's your island!" she pointed out. Knuckles grinned. "But it wasn't! Looks like for once your speed has cost you, because you beat me to the trap! This is priceless!" he snickered. Sonic turned to leave. "All right, you had your laugh! I'm gonna try to figure a way to change back now!" she grumbled. Knuckles hurried after her, planting himself in her path! "Huh? Odd... Usually I can't block you... Well, anyway, I bet you don't want me blabbing this to everyone yet, huh?" Knuckles grinned. Sonic stared at him. "What?" she stammered. "You heard me. You want me to keep my mouth shut about your little changes here? I wonder what Shadow would say..." he said. Sonic frowned. "What do you... want from me...?" she gasped. Sonic could see something stirring between Knuckles's legs. "You've done your share of taunting me and acting all superior... Now it's time to pay up. And since you're looking so sexy now, I guess I'll take your new equipment for a test drive!" he smirked devilishly.

Sonic was stunned. Here was one of her best friends, someone she once fought side by side to defeat Eggman with, now blackmailing her into having SEX! She couldn't believe it. Maybe it was because she herself would never do such a thing, but the idea someone else would do it to her hadn't occurred to her. Before she knew it, Knuckles had her backed against the rocky cliffside of Red Mountain, and Sonic could see his rapidly hardening erection! She gulped hard. Should she try to get away? If she ran, he'd just tell everyone what happened to her, and EVERYONE might be trying to do this to her. She didn't have much time to think, and before she could make up her mind, Knuckles had begun rubbing his cock along the outside of her pussy! "Ahhh!! All right... That's a good girl, Sonic." he grinned. Sonic gasped at feeling Knuckles's privates touch her, and it made her realize that it may be too late to run away. "Please, Knux... Stop! I might look like a girl, but I'm still Sonic!" she protested. Knuckles chuckled. "A female Sonic..." he said, removing his gloves before giving her ripe new melons a little squeeze. "They feel real enough to me! So, you might change back. That just means this is a once in a lifetime chance!" Knuckles figured. Sonic whimpered a little as Knuckles kept rubbing against her clit. It was making her wet, and it terrified her. Why was it making her wet? Did that mean she secretly liked this? Sonic shook her head. No, it was an involuntary thing. Sonic yelped as Knuckles knocked her back against the rocky cliff, and the red echidna looked apologetic for the first time. "My bad... I guess that's excessively uncomfortable. C'mere." he said, pulling her away from the wall. He was normally physically stronger than Sonic, but now she seemed completely at his mercy, any move she made in an opposite direction was instantly corrected by an extra tug on her arms. They were now standing in the middle of the cliff, and Knuckles had Sonic firmly in his grip, his arms around her waist. "Quit struggling! I'm still considering telling everyone, you know!" Knuckles warned. "No! Please, don't!!" she whined, not wanting to go through this with anyone else. Knuckles smirked, leaning in and pressing his lips against hers, forcing his tongue into her mouth! Sonic groaned loudly, shocked by this new sensation. She was being kissed by a guy!? Then again, it wasn't unpleasant. She moaned a little as Knuckles invaded her mouth with his tongue, brushing it against her own. As the kiss ended, he could see Sonic was blushing. She quickly looked away, though. "I bet this is what Eggman wanted... Way to fall for another of his tricks..." she remarked. Knuckles growled at this remark. "Oh, yeah?? Know what... Fine then. Struggle all you want. Suddenly, the thought of roughing you up a little just got pleasant, wise guy!" he snapped.

Knuckles swiftly pinned Sonic to the ground, causing her to yelp! He rubbed his cock against her entrance a bit more, feeling her wetness. "So, I'm the big dummy who's always the fall guy, huh? Then why are YOU the girl now, eh??" Knuckles growled, "Who has gotten wet for me, I might add..." he grinned. Sonic wanted to scream. This was too much. "N-no, I... That... Cut it out, Knuckles!!" she stammered. He didn't listen, he groped her breasts and played with her tits a bit. "Yeaaaah... You think you're so smart... Well, now I'M the one who's got the upper hand here, and you're gonna stay there and take it! ...Take my cum, that is..." he said, smiling devilishly. Sonic's eyes widened at this revelation. She wanted to say something, to talk him out of this, but Knuckles was already lining up his dick with her virgin vagina. "All right, Sonic... Brace yourself!" he grinned, penetrating her swiftly without further delay! "Aaaaaahh!! N-noo!!" she cried, gasping loudly as he started to move his rod inside her. He encountered no barrier, the transformation apparently didn't give her one. He moaned softly as he felt her insides against his cock for the first time, letting out soft chuckles as he watched Sonic squirm under him. "Mmm, yeah... It feels great!" he said, rubbing his hands along Sonic's sides, moving them up to her breasts and giving them a squeeze! Sonic moaned. She couldn't help it. He was touching her and rubbing her and it felt good, despite him being a little rough. "Aahh!! S-stop!! Knucklessss!!" she pleaded. Knuckles simply sped up his movements, thrusting his cock deeper into her depths! "No way, Sonic! This is WAY too satisfying! Ha ha! You're not so tough now, are ya?" he laughed, lowering his head to lick at her breasts a bit while he kept fucking away in her pussy! She might be able to take getting screwed, but this mocking was getting on her nerves, so she tried to push him off, but her female body wasn't anywhere near a match for Knuckles. She hoped it was just a temporary weakness due to the transformation, because she wanted to get back at him later. Knuckles seemed only to be encouraged by her struggling, it seemed to be turning him on a bit. "Ha! Too bad, Sonic! Looks like I win a round for a change!" he said. Clearly he had a bruised ego he was getting a little payback for, and Sonic was finally starting to understand that. She stopped struggling and held on to his sides, letting her pleasured moans escape as Knuckles had his way with her. He licked her neck and rubbed her breasts sensually as he quickened his pace in her passage further, getting himself closer and closer to his climax. "Hahh... Yeah!! I'm gonna do it, Sonic!! I'm gonna fill you up real good!" he grunted. Sonic still wasn't a big fan of this idea, and couldn't help protesting. "D...don't!! Kn-knuckles, think about... Aaaaah!! Oooh... No!!" she cried. However, there was no way to stop Knuckles now. He made a few more dramatic thrusts, signifying it was time. "Aaaaaaaaaaaahhhh!!! Take this, Sonic!!!" he shouted as he made one final, deep thrust, blasting his warm, gooey cum deep into her depths! "Gyaaaaaah!! NOOOO!!!" Sonic screamed as she felt the hot substance flow inside her, possibly entering her womb. Did she even have a functioning womb now? She shut her eyes tight, trying not to cry, but all the cum flowing into her, coupled with Knuckles pulling his cock out of her, was giving her one last bit of stimulation that was pushing her over the edge. She suddenly yelled loudly. "Wha-- Aaaaaaah!!!" and her juices splashed Knuckles's exiting cock as Sonic's own orgasm occurred! This made Knuckles smile triumphantly. "Well, well... Glad you enjoyed it!" he said.

As Sonic finally stood up, Knuckles watched with a cocky grin. "What?! What more do you want!?" Sonic snapped. Knuckles shrugged. "Oh, I was just thinking... I'm the only one who knows, huh? Tough secret to keep. I guess you can crash at my place whenever you like... Provided you're... nice to me." he said, licking his lips. Sonic frowned at first, but as she started to walk away, she stopped to glance at Knuckles. "I'll think about it..." she said with a wink. Next, she started off on her own, not quite sure where she was going. She couldn't lose focus. She had to try to figure a way back to her TRUE form.

Meanwhile, Eggman watched her from a monitor in his base. "Perfect. Exactly the reaction I was hoping for. Sonic... You will now cease to be a problem to me. You'll be far too busy keeping your own friends in check! And once I've conquered the world... You will be made to REALLY pay..." he said, twirling a collar around his finger perfectly sized for a certain hedgehog...

The End...?
