After everything our heroes had been through, across years of battles and lustful encounters, it was now beginning to sink in. It all couldn't last forever. Either some great evil would destroy them, or time would simply leave them all alone eventually. The biggest catalyst for this line of thinking was once the news had spread about Punchy and Rainbow's daughter. Those echidnas were moving on to a new chapter in their lives, and if the others weren't careful, life might pass them by before they could reach that chapter themselves. As much fun as sleeping around without a care was... it was time for our heroes to think about pairing up. Especially if the Doomsayer's long-standing prophecy of doomsday was true, because then, how much time did they have?

Shadow tossed some of these questions around in his head as he cleaned one of his guns, fresh from another mindless GUN mission. He was happier taking orders from the Commander than from that bigot, Gunner, but his mind was on anything but today. "Punchy... a creation of science...was able to produce a real offspring? Does that mean I can, too? ...Should the Ultimate Life Form even be bred?" he thought to himself, questions that he'd never really pondered before now. He heard someone approach, and glanced back to see Rouge the bat striding into the room. "Hmm, it's still a little weird, us working together for GUN. On the other hand, least I have someone to talk to." she said with a chuckle, sitting herself down in a chair close to Shadow. He glanced at her and nodded. "Yeah... Guess you're right." he mumbled. Rouge watched as he turned and placed his gun into a locker behind him. "You look a bit deep in thought. But then again, you always look broody like that." she teased. He glanced at her. Rouge was the closest thing he had to a girlfriend. If he was thinking thoughts like this, he should tell her. "Rouge... do you think someone like me... essentially a living weapon... should have a child?" he asked. She was completely caught off guard by the question, and just stared at him for a bit. Shadow stared back in annoyance. "It's just a question, Rouge. I'm not asking you to carry my hellspawn. Thanks for your input." he huffed, turning to leave. Rouge grabbed his arm and turned him to face her. "Shadow, you silly boy... You know, yours aren't the only genes that'd be involved." she teased before kissing him on the lips, now catching him off guard and making him blush. "If I found myself carrying your hellspawn... They'd be a treasure more precious to me than any gem." she whispered.

Shadow needed her, and he needed her that moment. He lifted her up into his arms. There was a shower connected to the locker room. Perfect. "If you want my offspring that badly, Rouge, I'll give it to you!" he smirked, carrying her to the privacy of the showers. Rouge blushed and grinned. "That sounds almost comittal, Shadow..." she teased. Placing her on her feet, Shadow took her by the shoulders and pinned her to the wall of the shower stall. "I don't need a frilly wedding... Just say you're mine, and I'll say I'm yours..." he whispered, kissing her neck as he started working off her tight black clothing. The bat was tempted to say it, but she rather enjoyed her freedom. "Ahh... No, Shadow, you'll have to take me to make me yours..." she huffed as her large breasts spilled out of the heart-shaped breastplate. As her clothing was falling to the floor, tossed outside the shower stall, Shadow's member was rising. He rubbed her soft, beautiful breasts and smirked at her. "I know you want it..." he said, backing up and letting her see his stiff pleasure pillar. Rouge knelt down in front of it and kissed his tip. "Oh, I can't resist good jewels..." she winked, leaning down and licking the dark hedgehog's balls. Shadow gasped softly and patted her head as he felt her tongue swish around his orbs. Then, her breasts were wrapped around his dick, and she began to lift and drop them along his length, licking his tip periodically. "Mmm... Why so sentimental, Shadow? Don't you enjoy these no-strings encounters?" she cooed, nuzzling his tip as her breasts massaged it. Shadow huffed and nodded. "Maybe I want to fuck you more often?" he murred, rubbing behind her ear. Rouge blushed. If they were mates, she could have Shadow on the regular... This was something to think about.

Soon, Rouge's hands and breasts were pressed to the door of the shower stall. Shadow's long black tool was rubbing her clit from behind, through her legs. His hands gently rubbed her bat wings. "Mmm, where do you want my cock, whore?" he whispered in a lightly playful tone. Rouge gasped as she felt her nipples rub against the door. "Ohh, hurry and fuck me, Shadow, before someone notices!" she huffed, and blushed lightly, "Go on... Try for that baby you want..." she cooed. Smirking widely, Shadow slipped his cock into her warm love tunnel, his hands moving down to grope her ass for support. Rouge's hands slipped against the door as she tried to steady herself. She gasped softly as she felt his thick member stretching her walls, the familiar feeling of being fucked by the ultimate life form making her start to moan lustfully. Shadow leaned in and kissed her neck before starting to thrust at a quick pace, trying indeed to make this fast so no one working at the GUN base would find them. Bracing herself against the door, Rouge's body was rocked by his cock, her breasts kneading against the door like a rough massage. "Ahhh... F-fuck, Shadow... That's it, right there!" she moaned, feeling him pound at her sensitive spots. He knew her body so well. Shadow smirked and slid his hands around to cup her breasts, despite the door banging his knuckles. "Aaahh... You...are mine, Rouge... Right?" he panted, feeling his cock throb as he rapidly pounded her, eager to plant his seed. Rouge rolled up her eyes, her wings flitting involuntarily. "Sh-shadow, ahh... I'll always be...yours!" she huffed, both of them moaning loudly as Shadow came, pumping his seed deep inside his bat girl lover! He turned her head and did his best to kiss her lips from this position before they panted and rested, embracing each other. Rouge was a free spirit, but Shadow knew he had her heart... And perhaps one day, her child...


Amy, too, had been thinking hard after learning about Punchy and Rainbow's bundle of joy. She wanted to find Sonic and ask when they should be thinking about a little hedgehoglet of their own. She thought she had found him. It was an honest mistake. But now she had to pay the price, and was down on her hands and knees as Spiny the Porcupine fucked her doggystyle in an alley. For once, he'd found a use for looking like Sonic that he enjoyed. Amy had gotten so close, she didn't realize her mistake until he'd started tearing off her clothes. Now his dick was slamming deep into her pussy, his heavy balls slapping her ass with each thrust. "Ahh, what was that you said? 'Ohh, Sonic, I wanna make a baby with you!'" he taunted, slapping her ass, "Alright, slut. Let's see if he can tell the difference if the baby's mine!" he smirked, speeding up his thrusts and smacking her ass again! Amy let out a lustful moan. The thing she hated most about this was how good it felt with this imposter. Panting, she arched her back and allowed his cock to please her needy walls. "Ahh, p-please, no... D-don't put a baby in me, ahh... O-only Sonic can do that..." she whimpered. Spiny reached around and groped her boobs, humping her roughly with a wide smirk. "What'll he think when he finds out how easily you let me fuck you? He'll never speak to you again, bitch..." he taunted. Realistically, Amy knew that wasn't true, but the threat in his tone was frightening. "Aaah, s-stop!" she panted. Spiny smirked. "Okay... Just for a moment. I want to preserve this moment..." he said with a devious grin.

Spiny propped up a phone, set up to record the rest of their lustful session. He sat against the wall, pulling Amy into his lap facing the camera. "Smile, babe... Let Sonic see how much you enjoy this..." he snickered, making Amy blush as he lowered her onto his cock again, sinking deep into her pussy. She gasped and looked away from the camera in shame. "N-noo... D-don't show Sonic..." she sniffled. Spiny pinched her nipples for the camera, making her moan as his dick thrusted up into her depths. "Don't you want him to see you happy, slut?" he teased, turning her head and roughly kissing her. She groaned into the kiss. He was nothing like Sonic, really. Still, this felt so dirty, and his cock was getting so deep, filling her body with pleasure. She felt his hands rub and squeeze her boobs, and she blushed again. He looked like Sonic. It was...an honest mistake, right? As the kiss broke, she leaned back into his chest and moaned in bliss. "F-fuck me, Spiny... Mmm, make me your pink bitch..." she whispered. Spiny's eyes widened, and he smirked widely. He held her hips and started to thrust up into her faster, her body bouncing on his cock for the camera! "Y-you're mine, ahh! N-now everyone can see it!" he panted, kissing her neck. Amy moaned lustfully, blushing at the camera. "Ohh... ohhh, I'm such a slut..." she panted, expressly for the show. Spiny hugged her waist and thrusted up roughly a couple more times before he came, his seed tainting Amy's body as he filled her! He then pulled her into a lustful kiss, after which she pinned him to the wall. "We're gonna watch the video, and then you're gonna delete it. You do that, and you can have as much protected fun with me as you want..." she offered. With a deep blush, Spiny agreed. He still hated Sonic's guts...but Amy it seemed was alright. This might be a beautiful secret friendship...


Kosmo was meeting Carrie at one of the empty buildings in the Raisol Sanctuary that afternoon. The morph didn't want to be involved in any Chaos Relic training or epic clashes with darkness. He was tired of fighting. But seeing Carrie now and then was a pleasure. It wasn't even as though they had much in common beyond being lab creations, but somehow that seemed enough. As he waited for her to arrive, Kosmo wondered where he saw his relationships in five years. "...I'm just not like Punchy. Can't see myself tied down to a mate and kid." he mumbled to himself. He'd spent the previous year female, he didn't even necessarily have a definite gender identity. If he found a mate, he or she would have to understand that. Perhaps even embrace it. Perhaps only another morph could tame him... but the only one he knew was Nova, an enemy. A shame... Kosmo truly enjoyed being on any and all sides of a sexual encounter. No one mate could give him that. These thoughts were on his mind as Carrie arrived. "Hey, Kosmo. Nice to see you around for a change. Nice of you to descend from your hidden fortress and consort with the mortals!" she teased. Kosmo chuckled and rolled his eyes. "Tell me, were you hiding around the corner invisible just to watch me wait like a bozo?" he asked. Carrie stuck her tongue out. "Like I don't have better things to do than watch you sweat." she chuckled. Kosmo tilted his head toward the empty building. "I thought that was exactly why you were here... To sweat with me and get a good pounding." he smirked. Kosmo didn't mince words around Carrie, nor did she with him. That bluntness had propelled their relationship to a lustful one. Carrie blushed at him. "Hold on, what were you mumbling a moment ago?" she asked. Kosmo rubbed his head. She was spying on him. "...This is just sex, right Carrie? I mean, how would we work. I'm a morph. I have needs you couldn't fulfill." he stated. Carrie chuckled. "Yeah, it's just sex...for now. But who says I can't serve your needs, huh?" she smirked. It was then that Kosmo felt something hard prod his ass. He jumped, and went to grab it, but found nothing. He blushed. It was her psychokinesis. "C-carrie…" he stammered, "This just got interesting..." he grinned.

Within the empty building, Kosmo witnessed Carrie scatter her clothing with her powers, letting them fall across the floor while her big yellow-furred breasts and wet pussy were freed for Kosmo's viewing pleasure. The morph used his own shapeshifting powers to add a thick, long dick between his own legs, pointed right at her. He smirked, feeling her powers lift him and move him to one of the few bits of furniture in the house, the bed. She carried herself as well, and positioned herself below him, letting his cock press against her flower. "Look at you grin. No more brooding loner now, eh?" Carrie teased, rubbing his butt. Kosmo lined himself up with her pussy and thrusted in roughly, enjoying her gasp as he felt her tight walls hug his rod. "That what they say about me? Brooding? Oh no, I have fun..." he snickered, leaning in to kiss her huge breasts. Carrie huffed softly as his cock started pounding into her. She twirled a finger and grinned, her powers effectively forming a phantom dick behind him that began to rub between his butt cheeks. Kosmo rolled up his eyes and felt his dick twitch excitedly as he thrusted into her faster. "That's it, babe... Ahh, fuck me while I fuck you...!" he urged her, sliding his hands up to grope her melons. Carrie let out a moan, looking up at him lustfully. The phantom dick plunged into the morph's ass, making him throw back his head and groan in pained pleasure. "F-fuck, Carrie, you're amazing!" he panted, pinning her down and slapping his hips into hers like a beast, his cock driving deep into her passage as she made that psychic cock stretch and ravage his rear hole! They both panted lustfully, looking into each other's eyes with desire. "K-kosmo, ahh... C-cum in me!" Carrie panted, feeling his dick throb. Kosmo leaned in and kissed her deeply, moaning into her mouth as he fired his seed, filling Carrie with blast after blast! A thought hit the back of his mind; "She can't cum in me, though..." In that moment of high bliss, Carrie's powers worked overtime and let her hear those thoughts. She smirked. She'd make him eat those words.

Carrie rolled them over so she was on top, and Kosmo looked up in disbelief as he watched something extraordinary happen. Carrie's crotch glowed brightly, and shining with that light, a long, thick cock sprung forth, accompanied by a heavy ball sack! Kosmo's eyes widened. "Wha-how??" he gasped. Carrie smirked. "I'm a mirage. While I can't transform my whole body like you, I can alter little bits to suit my needs...or desires." she winked. Kosmo blushed deeply, looking up at the futa mirage, and let out a cute sigh before his body erupted in a transformative glow! He took on a familiar hourglass figure, but that wasn't all! His tail split into a forked tail, and his head shape changed as well, to a more rodent-like shape. He was turning into a mirage like her...a female mirage! Kosmo maintained her purple coloring as the light faded, and looked up at Carrie with a deep blush. "I'm yours, Carrie! Claim me... as your mate!" she huffed. Carrie smirked, seeing Kosmo's legs spread and her pussy begging for her dick. "Look at you all submissive... I like it..." she murred, making a groping motion with her hands, which Kosmo ended up feeling against her breasts thanks to Carrie's psychokinesis. The mirage rubbed her dick against the morph's entrance, hearing her gasp lustfully. "Ahh... T-take me, Carrie..." she purred, feeling her breasts rubbed and squeezed by her powers. Carrie leaned in to kiss her, their forked tails entwining for a bit as their tongues danced. Before the kiss ended, Kosmo felt her walls parted by Carrie's cock, slipping into her passage nice and deep. She rolled up her eyes and moaned into the kiss. "Mmmmwa... Carrie... ahh, you're so big... f-fuck me..." she panted, leaning back into the mattress. Carrie smirked and held Kosmo's legs as she started to thrust into the morph! There was no mercy, she pounded her hard and rough, driving her dick deep into Kosmo's tunnel! Kosmo watched Carrie's breasts bounce as she fucked her, blushing to think her girlfriend was doing this. "C-chaos, Kosmo, your pussy feels so good!" she said with a blush of her own, "And so t-tight! I'm g-gonna cum so f-fast!" she panted, not slowing down her thrusts. Kosmo felt a hard squeeze to her breasts and moaned lustfully. Carrie could even cum? Kosmo knew now that he'd found his mate. The morph gripped at the bed sheets as she felt Carrie's tip prodding at her womb, her heavy balls slapping her as the morph was hilted! "G-go on... Knock me up, ahh..." she huffed, looking up at Carrie lovingly. The mirage's eyes widened, but she couldn't stop now. Thrust by thrust, she had gone too far, and now she cried out and pumped her load deep into Kosmo's womb! Carrie fell onto her chest, their breasts rubbing together as they rested. Kosmo kissed her, feeling her dick still stuffed in her pussy. "Carrie... it was never 'just sex' for me..." she admitted. Carrie blushed and held her mate. "Alright, but we can see other people. I mean, it'd be so easy for you to do that and me not know anyway..." she stated. Kosmo nodded and placed a hand on her belly. "Does a mirage shoot real...?" she asked. Carrie nuzzled him. "If I do, are you really okay carrying our baby?" she asked. Kosmo nodded. "I insist on it." she smiled.


Also in the Raisol Sanctuary at this time was Gemini. She had more on her mind than love at the moment, thinking about the burden of training the holders of the Chaos Relics as she sat on the bed in her room, in the small house she'd claimed while she was staying there. Timothy the fawn knocked on her door and was greeted by her as he entered. The friend she'd so long sought to save was now safe with her, and ready to aid her any way he could. He blushed lightly as he saw her sitting on the bed. He remembered how she took his virginity not too long ago. He didn't want their friendship to be weird, but he knew he'd like to fuck her again. She patted her hand on the side of the bed to invite him to sit. They didn't need a lot of words after all they'd been through. He sat beside her and sighed. "I know you're nervous, Gemini, but you'll do great. They'll be lucky to have you teach them, trust me." he smiled. Gemini nodded and smiled back. "Thanks, I'd rather not think about it too much right now. There's still so much to process, with Astra, Libra... The lies our teacher told... I still don't know what time is my real home..." she sighed. Timothy's ears flattened in sadness as he heard how distressed her friend was. He placed a comforting hand on her shoulder. She nuzzled it and blushed lightly. "Tim... Did you come to my bedroom hoping to have sex with me again?" she asked directly. Timothy turned bright red and babbled a bit in nervousness. "I, uh... Y-you're dealing with a lot, I just wanna be here for you..." he stammered. Her eyes gave him a sultry bedroom stare, and she lifted her shirt, revealing that she no longer wore a bra! "There are no masters to control us... You can be here for me by making me feel good..." she cooed. Gasping, Timothy felt his crotch springing to life. His best friend wanted him...and he was eager to oblige!

And so, Timothy laid back on the bed, Gemini's hands rubbing his fluffy chest as her naked crotch grinded his waist. The fawn's eyes were fixed on her lovely blue breasts, and she winked before guiding his hand up to touch them. "Tell me, Tim... Did you ever daydream about touching me like this when we were in training?" she whispered, moving up so his cock was pointing right into her entrance. Timothy blushed and bit his lip. "Ahh... I did spy on you undressing on a dare... You w-were younger and your b-boobs hadn't come in..." he said, blushing heavily. Gemini lowered herself onto his shaft, purring as she felt him sink inside her. "Ahhh... Naughty boy... But that doesn't answer my question..." she teased, gasping softly as she began to ride the fawn. Timothy moaned softly and gave her breasts a slight squeeze as he held them in his hands, his hips starting to jerk upwards into her as she slid up and down his shaft. "Ohhh... G-gemini, I couldn't imagine something as good as this..." he panted, looking up into her eyes and blushing, "B-but...I tried... You were so pretty, and... I'd imagine kissing you...touching you...even though it was against our rules..." he admitted, rubbing her nipples and watching her pant and moan in pleasure from the motions of his dick inside her. Gemini leaned in close, her lips nearing his. "Kiss me, touch me...break the rules, Tim. Fuck me..." she whispered, putting emphasis on the last bit. The fawn wrapped his arms around her and pressed his lips to hers, slipping his tongue into her mouth as he thrusted his cock upwards even faster! There was no going back, things would be weird between them now... but he decided he liked it as he felt her breasts press against his chest. Her tongue slid into his mouth, and her hand gripped his half-grown antler, rubbing it as she moaned into the kiss. He rolled up his eyes and pushed his cock deep inside his friend, knowing he would cum soon. "Ahhh, l-let me fill you, Gemini..." he huffed, licking her neck. She nuzzled him and purred. "I'm protected with magic... Go ahead, stud..." she huffed, kissing his cheek. With a lustful moan, Timothy blew his load, his cum shooting into his friend hard and making her gasp and cum along with him! She cuddled him into her arms, feeling pretty good right now...but something felt off. Like something was missing. It felt strange. She hadn't felt this way before with Silver, Libra and... She shrugged it off and nuzzled her friend. "Everything you dreamed of? I hope you won't feel weird about having a friendly romp whenever you feel like..." she cooed into his ear. Timothy blushed and hugged her close. "Better than my dreams... Gemini, I'm yours anytime you want me..." he whispered back. He knew this was only a friends thing, though. He knew Gemini well enough to tell her heart pined for another... But his mind couldn't help wondering... Could Libra possibly grow to like him?

To be continued...
