After Eggman's invasion of the world, aided by the powerful being known as Infinite, things had certainly changed for Sonic and his friends on an emotional level. The vaccine Bucky had given them, that had made them more prone to lust and gave them the ability to change gender as well, had worn off. The harems Sonic and Tails had built up and merged together had gone their separate ways, the war having reshuffled the priorities of all involved. Hurt by Tails' choice to hide her in a bunker rather than allow her to help him, Cream broke up with Tails. Overall, it seemed harder for Sonic and the other mobians to find time for physical intimacy as they were busy rebuilding their world. Even Bucky had apparently given up on his side-dream of attaining world peace through sexual bonding. When asked about it by Vortex and Zipp, he told them why. "Everyone was under the influence of my vaccine...and war broke out anyway. Granted, caused by forces not influenced by the vaccine... but the distraction...perhaps made us weaker rather than stronger. It seems I was wrong...world peace is not so easy to achieve." he sighed. Zipp shrugged. "Who cares about that, I just wanna get some..." he murmured. Vortex swatted him aside. "Who needsss it... Long asss Whisssk hatesss me..." he hissed. Chet, currently Experiment 16 due to being brought back from the grave by Bucky, had overheard this, and dashed to the rat's lab with a bit of curiosity on his face. "Vaccine... Was I dead for that? Damn, not fair! I woulda loved screwing a female Sonic...or whatever..." he murmured, finding a book on Bucky's lab table. The cover read: "Sexual Vaccines." Cracking it open, Chet gasped slightly. "Rejected serums? Hmmm... Some of these look too good to throw away... Where is he keeping them?" he mused.

In the meantime, Sonic had moved in to Tails' Workshop. Uncle Chuck was renovating Sonic's house after Eggman's little war, and who better to stay with than Tails, who was down a girlfriend, but up a boyfriend. After all, prior to the war, Sonic had agreed to try things out as something more than merely Tails' bro. He was still settling in at this point, but already a shy awkwardness washed over the pair of them whenever they were in the same room. They knew the conversation about it was coming. It was just a question of who would bring it up. Little did either of them suspect Tails would be the one. One morning as they sat and ate breakfast, he blurted it. "A-are we still gonna date, Sonic?" he asked shyly. Sonic blushed at the words. During the war, his main concern was just with surviving and then rallying the resistance to beat Eggman. With all that out of the way, now he had to consider the heart of his bro who thought him dead for half a year. He scratched his head. "W-well, are you cool for that? You've been through so much, Tails. Losing me, finding not-me, then finding me through Fera of all people..." he muttered. Tails chuckled softly. "Well, it's not like Fera's fixed up face meant much to me. I couldn't place it." he pointed out. Sonic nodded. "...Losing Cream..." he pointed out, noting his friend's ears droop at the mention, "If you're not up for it, there's no pressure, Tails." he stated. Tails looked up at him, gulping some juice, and then moved close to Sonic, taking him in his arms and quickly kissing him on the lips! Sonic was stunned, but he accepted the kiss, hugging Tails back. The fox tightened his hold on the hedgehog before releasing the lip lock. "I get you, Sonic... I know you don't want to hurt me. Just know that you could never hurt me... I love you. You're my hero..." he whispered, nuzzling him. Sonic blushed deeply. When Amy called him her hero, it always sounded laid on a bit thick, but from Tails it sounded genuine. He nuzzled the fox back and blushed. "Awww... Okay, then... What do you wanna do? Your house, you decide." he smiled.

Tails kissed him again before nuzzling into his neck. "Why don't I give you a proper boyfriend's welcome to my home?" he cooed. Sonic blushed hard. "Tails? Y-you mean... Ya know I can't turn female anymore..." he stammered. Tails wagged his tails and took Sonic's hand, leading him to the couch in the living room. "Yeah, Sonic, me and Shadow figured that out not too long ago, remember?" he giggled. Sonic smiled a little and laid himself down on the sofa, grinning up at Tails. "I like how take-charge you were, even with Shadow there and all the stuff on our minds... I wanna see more of you like that..." he winked, his hand gently stroking the fox's waist as he stood beside him. Tails was blushing now, but he was also starting to get hard. "Ohh... Well, if that's what you want..." he said, climbing on top of his hero and pinning his arms above his head before kissing him more roughly than before! Sonic let out an excited moan, his own dick growing and starting to poke and rub Tails' length. Tails then slid his hands down Sonic's sides as he kissed his neck, making the blue hedgehog gasp a tad girlishly. "T-tails... Ahh... Great, now everyone's topped me..." Sonic realized with a light chuckle. Tails gripped their two cocks, lining them together so he could frot with Sonic for a bit. "Ahhh... I guess you're just a real good bottom!" he smirked while Sonic smiled up almost shyly. "It feels best bottoming for you... I only tried to date Shadow before 'cuz he got me to turn female. Felt like I had to..." he admitted, letting out a soft purr as he felt Tails' dick rub against his. "Sure there wasn't something there, Sonic? It's okay if there was." Tails whispered, gently stroking off both their dicks at once. Sonic shivered at his careful hand work and smirked at him. "It could never be as deep as the bond we share, buddy... I love you, Tails." he whispered. Tails stopped jerking them off, his blue eyes gazing into Sonic's greens as though he'd dropped a bomb on him. He smiled cutely and giggled a little. "Sonic...so mushy! ....I love you too!" he cooed, lifting Sonic into his arms to kiss him passionately. Sonic whispered out in the middle of the kiss "Fuck me..." barely breaking contact between their lips to do so. Tails began to lightly finger Sonic's ass as they made out. He'd do it, this time not at Shadow's urging or to show off for the harem. He was gonna top Sonic FOR Sonic.

Once the kiss broke, Sonic let out a cute moan at the feel of Tails' fingers prodding his tight hole. He laid back and lifted his ass up a bit to give Tails a way into him. The fox blushed and withdrew his finger, wagging his tails. He felt pretty good about himself, seeing that Sonic WANTED him to top him. Sonic braced himself in a cute manner for the impending penetration. "Go as hard as you want, Tails... I can take it..." he cooed. Tails poked his tip against Sonic's hole, seeing him shiver at the touch, and he gently held the hedgehog's sides as he began to push into him. "Aaahh... S-sonic!! S-stop me...if I hurt you..." he gasped, feeling Sonic's tightness surround his cock once again. Sonic gasped softly and rested his hands on the fox's cute ass, giving it a nice squeeze. "You won't hurt me buddy... Now, c'mon, show me that confidence from when the harem was watching. Dominate me...make me yours..." he murred, winking up at him. Tails blushed deeper. It had been around a year since he'd felt quite that confident. But Sonic wanted it. So, Tails gulped a bit and pinned him down on the couch, nuzzling into his neck and kissing it. Sonic let out a pleased moan, and then gasped as Tails started to move his cock inside him. The cute fox held him down and humped into his ass, moving faster as Sonic loosened up. "Aaahh... S-sonic... You feel so good..." he panted, kissing his hero's cheek as he went. Sonic slid his hands up Tails' back, smiling as he saw the fox's tails wag behind him. "Ahh... y-yeah... Fuck me, bro... Ah, my dick is so hard for you..." he gasped, making Tails blush deeply. He could feel it, Sonic's cock was poking his belly and felt pretty stiff. He smiled a little, leaning up to nip Sonic's ear. He felt a flash of confidence. "You're mine, Sonic!" he murred, and leaned up, lifting Sonic's ass to get a better pounding position. As he started to thrust mercilessly into the blue hedgehog below him, he slid one of his hands to Sonic's cock and balls, rubbing and stroking them with a lustful smirk on his face. Sonic gasped and moaned in pleasure as Tails' dick searched out his weak spot, and he cried out once it was hit! "Ohhh... Oh, T-taaaails!!" His lustful cry made Tails feel even better, and the fox kept thrusting into that sweet spot as Sonic moaned submissively, grabbing at the furry sides of his foxy mate and trying to keep from cumming prematurely. Tails pulled Sonic into another lustful kiss, and as their tongues explored one another's mouths, they moaned loudly into the kiss, both of them hitting their peak! Tails came hard into Sonic, and the hedgehog sprayed his own seed onto both of their chests at the same time! They panted and kept kissing as Tails emptied his balls into his hero, leaving Sonic with a warm, full feeling. Once the kiss broke, Sonic held Tails close in his arms. "I hope you enjoyed that, buddy... We're doin' it a lot while I'm here!" he chuckled, nuzzling his cheek. Tails blushed and nuzzled him back. "With you the bottom? Aren't you embarrassed?" he giggled. Sonic kissed his cheek. "No shame in bein' topped by the best!" he winked, making Tails blush deeper. "D'awww... I love you, Sonic..." he cooed. "Love you, too, Tails." Sonic smiled, cuddling him.


Kosmo was lounging around the house he'd invited Punchy and Rainbow to stay with him at. Only, not as a he. Kosmo had chosen to lounge around in female form, and it was making Punchy uncomfortable now that he was reunited with his fiance. "Kosmo, do you have to sit around...girly? You're confusing my poor dick." he groaned. Kosmo glanced at him smugly. "Like you're not bi anyway." she taunted. Punchy crossed his arms. "Female preference! RAINBOW preference!" he snapped. "Rainbow preference makes you sound gay." Kosmo snickered. "He doesn't sound THAT happy, Three." Rainbow sighed. Kosmo stood up and crossed her arms. "FINE, I'll find someplace where I'm appreciated for my shapeshifting powers..." she huffed, "Can't let me try out being a chick for a while and see if I like it. What if I decide to stay this way, huh?" she snapped as she headed for the door. "Then you'll need CLOTHES!!" Punchy shouted. Rainbow scratched her head. "How come boys don't need clothes?" she asked. "Oh, not this again..." Punchy groaned. They suddenly heard crying in the next room. "Aaaand we woke Aurora. Thanks for consulting me before having our baby and NAMING her, by the way, Rainbow." Punchy grumbled as he headed off to check on the baby. Rainbow chuckled awkwardly. "In my defense, you said you couldn't have babies so I had every reason to be nervous! But look at her! She's GOTTA be yours!" she stated. "...Unless you've been sleepin' with that hawk..." Punchy grumbled.

Kosmo stuck out like a sore thumb outside even in male form if he didn't use a proper disguise. Walking around in a naked female form was potentially worse. But when the gargoyle mob showed up thinking they'd rape her, she certainly had a good time kicking their asses. Still, she realized this was the wrong kind of attention, and headed for the outskirts of town to think things over. There, who should she run into but Shadow the hedgehog, who seemed deep in thoughts of his own when she walked by. He almost stumbled in place to notice Kosmo was female today. "Kos...mo? Why are you... Wandering around like that?" he asked, clearly flustered. Kosmo glanced at him with a sly smirk, shaking her cute ass while swishing her tail for him. "See somethin' ya like?" she teased. Shadow looked away. "I'm free of Bucky's pathetic control. I'm done with random sex." he huffed. Kosmo shrugged. "Your loss. Wanna know something? I was NEVER under Bucky's control. No drugs, no freaky brain wave things. I've always endeavored to be far away from that madman. So anytime I did the deed...it was my choice." she smirked. Shadow scoffed. "I seem to recall raping you." he stated. "I seem to recall betting on the outcome and letting you win." Kosmo corrected, "And you didn't seem put off by me then... until I suggested trying a horse dick on you." Shadow almost cracked a smile, but still didn't look at Kosmo. "What's with the female form, though?" he asked. Kosmo sighed. "Would you believe Tails turned me on to it? I let him fuck me this way to get out of a potentially dangerous situation... Dangerous for the other person, obviously." she chuckled, "But...I liked it. Later Sonic fucked me this way, and Punchy..." she murmured, getting Shadow's attention. "So, what, everyone but me?" he said coyly. Kosmo chuckled softly. "I'd been gettin' comfy in this form sexually, so thought I'd try it for everyday use. Dunno about it right now..." she admitted. Shadow was admittedly starting to feel curious, but he still didn't want to go back to being the slut he saw himself as under Bucky's power. Kosmo glanced at him, seeing the hesitance in his eyes. "If you wanna fuck, just ask! We're... we're sorta friends, Shadow. It's not that weird, even if you're not affected by some uber aphrodisiac." she stated. Shadow glanced at her and opened his mouth to speak. Then, he smirked a bit. It wasn't in his nature to be this shy, and Kosmo was offering. "Alright, slut. Want more of the ultimate cock? You got it!" he winked.

Shadow carried Kosmo to the remains of Hollow Manor. The woods surrounding the burned down mansion would be a perfectly private place. "Why'd you make me carry you?" he muttered. Kosmo leaned against a tree, bracing herself for what was to come. "Helps me get into character... You do want a submissive morph bitch, don't you?" she winked. Shadow walked over and planted his hands upon the tree on either side of her. "I don't need you to 'act' submissive... I'll pound you into submission!" he smirked, forcefully kissing her, his tongue fighting her tongue for entry. Kosmo gasped softly before submitting, letting Shadow claim her mouth in a rough kiss. She rubbed her hands along his sides, murring into the kiss until it broke. "Ahhh... Show me what you got, then, Mister Ultimate..." she winked. Shadow was now rock hard, and started to rub his dick along her entrance. His hands pinned her to the tree by her shoulders. It felt too easy, honestly, since Kosmo could probably morph out of this if she wanted. He had to remind himself that the goal wasn't to rape her. The goal was to BREAK her. In a moment, he plowed his cock deep into Kosmo's pussy, and she backed into the tree and moaned out. "Ooohh, there's that big black cock..." she panted. Shadow smirked and continued to hold her down with one hand while his other slid down and groped her breast. "Wow... So soft, Kosmo..." he murred, starting to roughly thrust into her pussy as she gasped and moaned in response. "Wanna suck? Mmm, I can lactate if you're into that..." she winked. Shadow simply squeezed her breast and adjusted their position so he was pounding her pussy at a more rapid pace. "Aaaahh!! You w-won't be able to stand w-when I'm through!" he huffed, searching for her sweet spot. But Kosmo didn't have a sweet spot to exploit...not at the moment. She wanted to prove he liked it, and what better way than to make him go overboard and cum inside her? Besides, no sweet spot was needed. His rapid, rough thrusts were driving her wild. She kissed and licked the arm that held her down, rubbing Shadow's chest as she enjoyed his dominance. "Aaaahh!! Ohhh, f-fuck me!! I'm your bitch, Shadow!!" she wailed, her pussy tightening as she neared her peak. Shadow gasped and found himself licking at her tits. "Oh, chaos... I'm l-loving this..." he thought, his eyes rolling back as he made a few more thrusts. Both cried out in ecstasy as Shadow came, and Kosmo followed! His seed filled the morph and rolled down her leg. "Aaaahh... You know... I can choose if you have a chance at knocking me up or not..." she purred, making Shadow growl and hastily pull out. "Hehe! Don't worry, I'm not carrying any eggs right now!" she snickered, "...Or am I?" Shadow glanced at her and rolled his eyes. "Keep that up and I won't fuck you again." he snickered. Kosmo grinned at him. "You won't be able to resist..." she teased. The pair smirked at each other before heading their separate ways. Kosmo slid a hand along her figure, looking over it with a light smile as she walked. "This form may just be an improvement..." she said to herself with a grin.


Amy Rose wailed out as she bounced atop the big, stiff cock under her. Her breasts bounced as she rode her partner, a look of sheer lust on her face as she moaned. "Oh, fuck me... Fuck me!! I-I'm so hot for you...!!" she panted as his hands rubbed her thighs. She rolled her eyes up and moaned out as she came, and her partner followed, pumping her full of his seed, murring at his conquest of Sonic's girl. Amy began to pass out, and her partner plopped her on her bed. He placed a bottle of morning-after pills in her hand. Obviously didn't want any unwanted kids from this encounter. Then, he picked up her discarded panties. A smirk came to the face of Chet the cheetah as he claimed Amy's undergarment as his prize. "That little aphrodisiac in Bucky's lab was a good start... Amy'll probably deny anything if asked, but I got proof here..." he murmured, sniffing her panties briefly before collecting his clothes and heading for the door. "...Sonic & Tails with their harems. Bucky with his mind control. I'll out-fuck 'em all... And I'll get quite a collection for my trouble..." he grinned, his head filled with plans. Who would be his next target...?
