The story thus far:
Sonic finally caught up with Dr. Eggman, who revealed that the signal causing male furries to go sex-crazed was actually part of Bucky the Rat's scheme! Before Sonic could learn much more, he learned that Eggman's base was about to explode! He acted fast, and helped Amy, Rouge, and the now-female Tails escape the base before it exploded, collapsing and trapping several people inside. Bucky's experiments have set to work capturing some on the people trapped in the rubble, including Guard and Heather. Meanwhile, Illusi the Shrew helped Silver and Blaze escape. Now, Sonic is looking for other survivors while Tails is busy attempting to reverse what Bucky did to her, and turn herself back into a boy.
Now, on to the next chapter!


Tails was busy tinkering with a few gadgets in her workshop, trying to fashion a device to change her back into a male. Amy was sitting nearby. She sighed miserably in her boredom. "A whole base full of sex-crazed lunatics, and Cream got more action than me... Of course, I only wanted Sonic, but as usual, as soon as I find him he has to run off and save someone..." she muttered. Tails made a few thoughtful murmurs and then chuckled to herself. "I think I've done it! I'm no expert on sex changes, but I think this should work. Help me out here, Amy!" she said, turning around and handing the pink hedgehog a goofy looking laser device. "What's this'" she asked. Tails backed away and raised her arms. "It's a gender-changing laser. Shoot me with it." she said. Amy looked at her a little awkwardly. "Shoot you'! But what if it doesn't work right'" she asked. "It shouldn't be dangerous. Just do it!" Tails insisted. Amy shrugged. "All right... You asked for it..." She fired the laser at Tails, and when it hit, a blinding light covered everything! Amy shielded her eyes and gasped in horror. "Oh-my-god! Tails! Are you OK' Are you dead' Don't be dead!" she shouted as she slowly opened her eyes. Tails was still standing, and in fact, was no longer a girl! His device had been a success! As he slowly opened his eyes, he saw Amy blushing heavily. "See, I told you I'd be all ri.... ohhh..." Tails gasped as he realized where Amy was looking. His device had worked perfectly, and his penis was out to prove it. Tails started blushing as well. "Ummm... S-sorry about that, A-amy..." he stammered. Amy tried to get a hold of herself, but she was shocked at how well endowed Tails was. She slowly started to smile. "Very nice, Tails. I'm impressed." she said. Tails continued blushing, but slowly started to relax. "Oh, well... Thanks, I guess..." he said with a goofy smile. Amy slowly walked over, setting the laser down on Tails' work bench before getting a closer look at his cock. "You know, Tails... I feel bad about seeing you naked like that. I guess the only thing to do is to let you see me naked, too..." she whispered. Tails gulped. "A-are you sure' What about..." he stammered. Amy shushed him. "Just this once... It'll be our secret..." she said.


Bucky was pacing in the newly added prison area of his lab. There were a few captives in the cells already, and as he looked in at Heather, Team GeneX arrived with another captive in tow. Crash was carrying Cream the Rabbit in his arms, with Vortex and Zipp following behind him. "We have another one, boss." Crash said. "Not here again! Let me go!!" Cream whimpered. Bucky chuckled. "All in good time, but not until I'm ready. Lock her in an empty cell." he ordered. Crash and Zipp went off to lock up Cream, but Vortex remained with Bucky. "If I may asssk, sssir... What isss the purpossse of thessse experimentsss'" he asked. Bucky sighed. "You wouldn't understand. Suffice it to say that my goal has always been to create life. Project GeneX-X-X should have a high yield. That is all you need to know." he said. Vortex shrugged. "Asss long asss there issss a purpossse to it." he muttered. Bucky looked thoughtful. "Rounding up our test subjects is taking longer than I would like. I suppose it is because of the destruction of the doctor's base. Have you thought to turn on the backup sex drive inducer signals yet' I imagine it would make rounding up the rest of them easier." he said. "Already done, ssssir. We'll head back out right away." Vortex replied. Bucky nodded and started walking away. "Keep the males and females separated for now. I'll be in my lab getting ready for the main event. This may very well be my greatest experiment..." he said. Zipp and Crash soon joined Vortex. "He'sss crazy, you know." he hissed. Zipp chuckled. "I know. That's why I'm enjoying this so much!" he said. Crash shrugged. "Crazy or not, I think he's mostly harmless. We'll see where this experiment of his goes, and decide what to do from there." he said. Vortex slapped him. "Don't be insssubordinate! We mussst obey the massster! No matter what..." he hissed before leading them both out. "Vortex is crazy, too..." Zipp whispered. "You would know." Crash replied.


Sonic was running around the rubble of Eggman's base, looking for any sign of survivors. So far, he hadn't had any luck, but now, he came upon a section of rubble that was shifting. He stopped to check it out, and soon a fist burst out from under the rubble! With a little more digging, Knuckles finally managed to escape from the base. Sonic waved to him. "Yo, Knuckles. I didn't know you were paying Eggman a visit." he said. "It's a long story, Sonic." Knuckles grumbled. "Well, tell it somewhere with more stable ground!" Sonic said, grabbing Knuckles and carrying him away from the remains of the base. Once they were on the stable ground of the Mystic Ruins jungle, Knuckles related parts of his story to Sonic, leaving out as many unflattering parts as he could, but he couldn't get around telling Sonic about how he'd been captured. "Oh, gee, I was running around the base trying to save everyone and you were chilling out in a cell!" Sonic teased. Knuckles growled at him. "Knock it off, Sonic. It's not like you've never been caught before!" he said. Sonic chuckled. "You mean Prison Island' I came quietly so I could find out about Shadow. YOU just got dragged into Eggman's base kicking and screaming!" he joked. Knuckles was in no mood for this. "Shut up, Sonic! I didn't take any crap from Rouge today and I'm not taking it from you!" he warned. Sonic rolled his eyes. "You're right. I'm sure you didn't get your butt kicked. Eggman probably TRICKED you into the cell!" he said. This was the last straw. "You asked for it!!" Knuckles yelled, socking him in the gut! "Ooof!! Hey!!" Sonic growled, only to have Knuckles push him to the ground! "I'm fed up with your jokes! Maybe I oughta teach you a lesson the way I taught Rouge a lesson!" Knuckles yelled. Sonic raised an eyebrow. Knuckles had left out this part of his story. "And how's that'" he asked. Knuckles jumped on top of Sonic, pinning him to the ground! There was a certain madness in his eyes that told Sonic he may not entirely be in his right mind. "First off, I'm gonna overpower you. Which I guess I just did, 'cuz I AM stronger! So next... I'm gonna rape your sorry ass!" he yelled. Sonic looked up at him with a nervous smile. "Um... Did I happen to tell you about the weird signal that's making everyone sex crazed'" he asked. Knuckles got up and flipped Sonic over so that he was on his stomach, but before he was turned, Sonic briefly got a glimpse of Knuckles' hard, throbbing cock. "Like I'm gonna just LET you do this'" he said, attempting to crawl away. Knuckles seized him by the legs and started pulling him back as he grunted and growled. Sonic was tough, but Knuckles was in a much more advantageous position at the moment. "Struggle and scream all you want, Sonic... I'm gonna enjoy this, big time!" Knuckles grinned, lowering his cock towards Sonic's ass. Sonic struggled a bit more, but came to realize that it was too late. "Oh... Shit... Knuckles is really gonna fuck me! No!!" he thought, clawing at the ground desperately. Knuckles wore an evil smile. "Take this, Sonic!" With that, Knuckles slammed his cock into Sonic's rear, penetrating him with all his might! Sonic howled in pain, filling Knuckles with a sense of satisfaction. "Brace yourself, I'm just getting started!" he said.


Amy was standing with her back against the wall. She was fully naked and beckoning Tails to approach her. Tails stared at her with his mouth hanging open. She was hot, and her sexy curves mesmerized him. "A-amy... We're gonna... have sex, aren't we'" he asked. Amy grinned seductively. "I think we are. Look how wet you made me, Tails... Besides... Don't you think you ought to test your boy parts' To make sure you changed back right'" she reasoned. Tails shivered. "You think Sonic will buy that'" he asked. Amy winked. "I bet Sonic owes me one. He can't try to tell me he didn't fall to temptation once with that crazy signal going on." she said. Tails nodded. "It's probably affecting us right now..." he realized, slowly walking towards her. "I don't think I care..." Amy sighed, grabbing one of her breasts, "Take me, Tails..." He reached out and held her waist, eagerly inching his foxhood towards her flower. "I'll do my best, Amy..." he said, suddenly pressing his lips against hers in a surprise kiss! His tongue slid into her mouth and met hers, and as they kissed, he pushed his cock slowly into her tight passage. Amy moaned into his mouth, and when the kiss ended, she looked into his eyes affectionately. "That was so cute... Here I thought you'd be all shy." she said. Tails slowly started to move inside her, slowly moving his hands up her body to feel her wonderful curves. "Um... Thanks, Amy..." Actually, he was feeling a bit shy, but he kept going anyway. He wondered if it was his own doing, or the signal, but he didn't waste too much time questioning it. "Mmmm... So gentle... So soft..." Amy sighed, holding on to Tails and nuzzling his chest. He sped up gradually and carefully, to make sure Amy was comfortable the entire time. He slowly moved his hands towards her breasts. "May I... touch them'" he asked almost bashfully. Amy blushed and nodded. "Why don't you give 'em a good squeeze'" she smirked. He slowly took them in his hands, brushing his fingers over her tits, making her sigh. He then grinned and squeezed them tight! "Aaaah!! Ha ha!! That's it, Tails!" she chuckled. He chuckled as well and started pushing his cock into her even faster. He was still pretty gentle with her, but he was holding back less as he got closer to his climax. Amy thrusted her hips along, eagerly urging him to finish inside her! "Aaaahhh... Yes!! That's it, Tails!! You're so good!! Ohhh!! Ahhh!! T-taaaails!!" Amy shouted, feeling herself nearing her peak. Tails kept it up, his tails spinning as his excitement was building. "Ahh... Yeah... Amy!! This is... Aaaahhh!! Whoa!!" They continued moaning and shouting as they went, holding on to each other as their pleasure built up. Finally, they both made one final thrust, shouting each other's name as they came! Tails pushed his cock as deep as it would go, planting his seed deep inside her as her cum trickled down their legs! When it was over, Tails slowly pulled out of her, and they stood side by side, panting. Amy took his hand. "Tails... That was amazing... If I ever leave Sonic, which I won't, maybe I'll consider you next..." she said, smiling. Tails nodded. "I'd like that. Maybe..." he said. Amy sighed and glanced towards the door. "Sonic's not back yet..." she realized. Tails chuckled nervously. "I'm kinda glad, but maybe we better see if he needs any help. After we wash up, of course!"


It was a safe bet that Sonic could use a bit of help, but whether he'd actually want said help to see him in the situation he was in could be debated. Knuckles had him pinned face down on the ground, and was ravaging the helpless hedgehog's ass with his cock! Sonic screamed and protested, but Knuckles kept banging again and again. "Ahhh... Uhhh, Sonic, your ass is so tight! Heh, I like it!" he said, enjoying his current dominance over his frequent rival. Sonic grunted and groaned, trying to suppress any further screaming, since it only seemed to encourage him. It hurt like hell, he wasn't used to being fucked like this, and Knuckles certainly wasn't going easy on him. Knuckles made a few more thrusts, and then stopped for a moment. "Well, now that you're softened up... Let's switch to a more entertaining position!" He pulled out of Sonic's ass and flipped him over again, so that Sonic was now on his back. Sonic thought about trying to get away now that Knuckles had pulled out, but he was pretty banged up, and he didn't expect he'd get far anyway. No, for now, Knuckles had won. The red echidna smirked at Sonic's defiant expression, and then noticed that his cock had been coaxed out as well. "Enjoying your beating Sonic, hmm'" he said, closing his fist over Sonic's cock and squeezing it for a moment. Sonic scowled at him. "Suck it, Knux." he snapped. Knuckles released Sonic's cock from his grip. "I'm tempted to kick it, but why should I' I've already got you pinned..." he said, grabbing Sonic's rear and positioning him so that his cock could re-enter, "...And from this vantage point, I can see the look on your face when I blast your insides with my cum!" Without further ado, Knuckles plunged his cock back into Sonic's ass hole, watching Sonic wince as he was penetrated once again! Sonic knew it was probably the strange signal driving Knuckles over the edge, but he still felt Knuckles was enjoying this way too much. "Aaaahhh... S-stop it, Knux!! You're startin' to seem gay!" he shouted. Knuckles snickered at him and started thrusting his cock inside him again, holding on to Sonic's waist as he went! "C'mon, Sonic' Can't you force me off, tough guy' Ha ha ha!" he laughed, grabbing Sonic's cock and pumping it in his hand as he kept fucking his rival. Sonic squirmed and groaned. He attempted to grab at Knuckles and push him away, but he couldn't get a grip on him. He didn't want to admit defeat, but there was little else he could do. Knuckles kept fucking him harder and faster, panting and laughing and taunting him all the while. He kept playing with Sonic's penis, quickly causing precum to sprout from it. Sonic gasped as the pain was fading and began to be replaced with pleasure. "Aaaahhh... Aaaahhhh... N-nooo!! K-knucklessss!! St-stooooaaaaahhh!!" he moaned, unable to hide the pleasure he was feeling. Knuckles laughed. "Ready, Sonic' As much as I've enjoyed watching you squirm and all that, I think it's time for me to finish this! HERE IT COMES!!" He released Sonic's cock and pushed his own as hard as he could, slamming Sonic with everything he had! Sonic screamed and yelled, but not quite what either of them expected. "Ohhh... Aaaahhh... Y-yeeeeeeeaaaaaaaahhhhhhh!!!" Knuckles let out a similar, but more triumphant yell as his cum flooded into Sonic's butt, even leaking out a bit due to the amount! Knuckles chuckled and pulled out before he was done, letting the last of his load fall over Sonic's chest! Sonic laid there, breathing heavily, battered and beaten. Knuckles had sure won this "argument." He smiled as he admired his handiwork. "About time I won a round. Maybe now you'll respect me a little more." he said. Sonic stared up at him with a look of defeat. "I... can't believe... you did that. I guess I should be impressed with that sucker-punch of yours." he grinned. Knuckles sighed, and was about to say something, when he was struck from behind hard! He fell over, unconscious, and Sonic saw Vortex, Crash, and Zipp standing over them! "Two more prissssonerssss... Let'ssss take them away..." Vortex said. Sonic whimpered nervously. "Can this day get any worse'" he groaned.


In another area just outside the base was Gemini the Fennec and Punchy the Echidna. They hadn't gotten far into the base before it exploded, but they'd at least managed to find Gemini's wand, which Metal Sonic had discarded, assuming it to be worthless. They escaped the explosion, but were feeling bad about everyone who was still inside. "I feel like such a failure..." Gemini said. Punchy sighed. "There wasn't much you could do. I mean, you got knocked out for who knows how long..." he reasoned. Gemini looked at the massive pile of rubble where the base used to be. "Maybe there are still people alive inside there. With my magic, maybe I can help them..." she figured. Punchy suddenly felt a stirring between his legs. "Um... Gemini... You know that weird thing you told me about where Knuckles couldn't control his urge to screw you'" he whimpered. Gemini glanced at him and shivered. "Oh, thanks for the warning. I'm afraid I don't have time for that now. Abra-ka-warpra!" she said, using her magic to teleport away. Punchy frowned once she was gone. "Why did I tell her that...' Am I goin' soft'" he muttered. Suddenly, Illusi, Blaze, and Silver appeared nearby! Punchy jumped in surprise. "Gah! It's bad enough when you do that alone, Illusi! Now you gotta bring backup!' Wait, Blaze!'" he said, feeling his crotch stir again. Illusi rolled his eyes. "Sorry, Dark One. No time to chat. I have to look for more survivors." he said, disappearing again. Silver took off on his own. "No more time! I must save the future!" he said. Blaze looked at Punchy awkwardly. "Nothing happened... Not that it's any of your business. Well, I should be going!" she said, running off in the direction of the destroyed base, probably hoping to find a clue as to where to find Eggman now. Punchy growled in frustration. "Oh, no you don't! Wait up!" he muttered, chasing after her.
