Knuckles’ Jewels- Good Future (Epilogue)
Six years had passed since Knuckles and Rouge’s first birth, whereupon seven new echidnas came into the world. And what special children those seven turned out to be; as early as the first month, each of the children revealed themselves to have inherited one or both of their parent’s special abilities: Knuckles’ super strength and Rouge’s powerful kicks. Many toys Knux and Rouge gave to their seven firstborns ended up getting destroyed on accident by those with the super strength (usually followed by crying) and the two had to be careful around those with their mother’s kicks, especially if combined with the super strength. Once Rouge’s second pregnancy had started, Knuckles had to be the only one to handle the strong kickers to prevent any accidental miscarriages. Fortunately, the only area of Knuckles those kickers ever managed to hit were his indestructible testicles, though it was much better for the echidna to get his balls busted by his mate than his spawn. And needless to say, all future brood would go on to inherit their parent’s abilities.

And no doubt an influence of the Chaos Emeralds, which were mostly responsible for their existence, Knux and Rouge’s first seven offspring displayed ‘chaotic’ personalities as soon as their consciousness developed. Thankfully the behavior was never too bad or too unruly, but the seven echidna children were wild and full of energy; their parents dreaded the moment any of those seven kids learned to walk, for they quickly learned how to run, and ran amok until they tired out, which was a lengthy process in itself and the resting period never lasted long, especially once they became toddlers. 

Of course, Knuckles and Rouge never let the chaotic antics of their kids bring them down; the red echidna was willing to bear any burden to repopulate his nearly extinct species, and tireless children were exactly the kind of ‘spice’ Rouge desired in her life. It helped that the two had some aid in the form of Tikal, Chaos, and some of the other girls when they were available, and their children after the first seven were less chaotic (but not without toddler eccentricness). 

And the bat and echidna very much continued their sexual activities whilst raising their increasing amount of children; Rouge busting her mate’s echidna-stones with great passion, especially during pregnancy, and Knuckles allowing said busting of his nuts and fucking the bat raw when he was allowed. The two’s libido were not one diminished by their many litters of children, and did not hesitate to keep up the ballbusting and sex even when their kids were present. 

If anything, Knuckles and Rouge became extra horny when their children watched their mother bust their father’s balls and daddy pounding into mommy. The two never really saw a point to shielding their children away from sex and sexual activities: it is a fundamental part of life, after all. As Knux liked to see it, it was being honest with their kids and how things worked. Obviously though, they never involved their kids in their adult activities and strictly forbade the children from replicating their actions. Although they could not object to any accidental blows to Knux’s jewels. 

...

One day, the first three litters of new echidnas gathered in the Chao Ruins (one of the safer spots of Angel Island for the four to six year olds), with Knuckles watching over them from atop a tall pillar; making certain they are safe and behaved. 

The tykes got together in a circle and discussed what game to play… 

“How about tag?” Spoke a six-year-old girl echidna with white fur and strong looking legs and hip. 

“No way, ‘Rouge Jr.’!” Shouted a boy echidna with purple fur, five years of age. “You always win!” 

Rouge Jr. spread her legs apart and stretched them from side to side. “Hey, not my fault I got Mom’s legs!” She halted her leg stretching and stood up straight. “But fine. What else you all got in mind?” 

The echidna toddlers thought for a moment when one came up with something. “Oh! How about we get some chalk and draw on the pillars?” 

“Are you serious?! These ruins are very important to Dad! Even if he weren’t watching us right now, he’d throw a fit the moment he saw the drawings!” 

“R-right…” 

The tots went into thought once more when after a minute, one of the youngest ones got an idea. “How about hide and seek?” 

“Hey yeah! That’s a game where no one is better or worse than anyone else!” 

“And as long as we don’t mess up the ruins, Dad won’t get mad at us!” 

“It’s settled then! But before we hide, who will seek?” 

“I vote Cherry!” 

The cherry-colored girl echidna turned to the sibling who called that vote with an angry look. “Hey! Why me?” 

“Because us younger ones are seekers most of the time! About time you oldest ones were the seeker.” 

“Okay, but why me and not any of the other oldest, like the Juniors?” 

A silent pause went by, during which all the other children shrugged at Cherry’s question. Suddenly, all of them but Cherry run in various directions with laughter. “Count to fifty! And no peeking!” One of them called out to Cherry. 

“Wha-?! HEY!” Cherry shouted. She was about to voice another objection, but realized the futility and huffed. “Jerks!” 

Knuckles laughed a bit at this event. “They really are Rouge’s kids.” He remarked, and then formed a funnel around his mouth with his hands. “Next time, you guys draw straws! Okay?” 

“Okay, Daddy!” All the echidna children replied, and the game properly started. 

Cherry counted up to fifty with her eyes solidly covered, and as she did so, all her siblings frantically sought good hiding spots. Luckily for them, there was plenty of that in the form of broken pillars, boulders, trees, and bushes for them to hide behind. But of course, there were so many of them and only enough room for each one to hide, and a strict rule these echidna toddlers had for hide and seek was to never share hiding spots. 

Almost as quickly as they had started, all the available hiding spots had been taken. The four year old kids, otherwise known as the third litter, being as young as they are, claimed the most obvious hiding spots, which mainly consisted of hiding behind objects and hoping Cherry would not look around. The five year olds, the result of Rouge’s second pregnancy, were a fair bit more clever with their hiding, using the cover of shadows and hiding atop one of the more intact pillars and tall trees, but still easily seen with an adjustment of perspective on Cherry’s part. And so, of course, the firstborns (sans Cherry) concealed themselves the best; having been taught how to dig by their parents, they dug themselves little holes which they hid in and did so in areas where they would not be readily noticed. 

Wanting to be more creative though, Rouge Jr. hid herself in a small body of water, using a reed as a makeshift snorkel so as to not drown. And Crimson, a dark red boy who had been born at the exact same time as Cherry, hid himself within a bush. However, that was more a desperate last second decision than creativity on his part, as Cherry nearly finished counting when he managed to conceal himself: and he could not even conceal all of himself, as his blood red balls could be seen hanging out in the open. The young echidna was just lucky that the bush he hid in happened to have red berries and simply hoped that none of his siblings would get hungry. 

“Ready or not, here I come!” Cherry announced once she counted fifty, and immediately searched her echidna brothers and sisters. 

Being just as wise as her fellow firstborns, with some training from their mother and father, Cherry was able to find the four-year-olds very easily. And as per the ancient tradition, once found, the hiders became seekers and would stand to lose the game alongside Cherry if the others were not found in time. And with their help, Cherry found the rest of the echidna brood before the designated time limit was over. Well, the rest but one: Crimson. 

Cherry checked around the shrubbery for her brother when she noticed a peculiar set berries hanging from within one of the bushes. The girl inspected the fruit and realized that it was a different sort of fruit altogether, the sort that hung below her father and brothers. An evil smile grew on Cherry’s muzzle as she thought up a fun way to expose the boy. 

“Wow, these two berries are big!” she announced, loud enough for Knuckles to hear turn his attention toward her. Crimson flinched with fear that he had been found, which caused his balls to instinctively clench up. Cherry saw that ball clenching and giggled with a devious tone as her siblings gathered to witness the ‘big berries’. “These would’ve made a great snack! But they look so nasty to eat!” Crimson blushed with humiliation and sweat with nervousness as his sister, whom he entered the world with, reared back her arm with her fist aimed at his nuggets. “There’s only one thing that can be done with such big and nasty fruit!” 

Knuckles’ eyes shot open as it became clear what Cherry was about to do and he was about to yell for her to stop. However, before he could do so, his daughter delivered a powerful punch to his son’s nuts. The entire push shook from the impact and a pained scream was heard, followed by Crimson tumbling out of the bush. 

“Oowww!!!” Crimson cried and immediately clutched his crotch. 

The kid-nas laughed at their brother’s pain while Cherry beamed with pride at winning the game. However, both the laughter and glory were cut short by a loud and furious ‘CHERRY!!!’. The children turned to behind themselves and see their father, the Red Rad himself, descend from the pillar via gliding down with his dreadlocks and land like a superhero. Knux gave Cherry a disciplinary glare and then went over to the downed Crimson. 

“How bad is the pain, Crimson? Your balls aren’t damaged, right?” 

The dark red boy lightly pressed and squeezed his orbs to feel for damage. “Mm… Yeah, they’re fine. Hurt, but fine…” 

Knuckles helped the firstborn up and then turned to Cherry with his fists to his hip. “What have I told you guys about hitting each other in the private parts?” 

Cherry crossed her arms with a defensive expression. “Aw come on, Dad! He was hiding in that bush with his balls completely exposed! If anything, I taught him a valuable lesson.” 

Knux sighed. “I understand they were a tempting target. And that is a good lesson... But you all will carry the important duty of repopulating the echidna species when you come of age. We’re the only ones alive, and for a long time I was the only one till I had you children. We can’t risk any of you becoming infertile from rough play, before you even reach puberty.” 

Crimson got beside his dad and grabbed his hand with a pleading expression. “Dad, it’s okay! As much as that punch hurt, it was pretty funny. And I don’t like this extra attention you’re drawing to me…” 

Knuckles Jr., who very much resembled his father but lacking the white crescent symbol on his chest, gave his same-aged brother a thumbs up. “Don’t worry, bro! I’ll share the attention with ya!” The boy spread his own legs and brought special attention to his nuts. His other siblings got the idea and one of his younger sisters immediately gave him a good kick to that sack, upon which he fell to his knees with a grin. 

Knuckles’ brows furrowed even further and he scowled with bared fangs. “ENOUGH! One more hit to the balls, or a hit to the vajayjay for the girls, and playtime is over! Do I make myself clear?!” 

Rouge Jr. put her hands to her hip. “But you let Mommy hit you in your boy bag all the time.” 

“Yeah!” called out one of the younger children. “She also does it in way more painful ways!” 

“Your balls are even a different color because of her! How are you not ‘infertile’ by now?” 

Knuckles looked down to his blue’d jewels and sighed. “Well, in my case, I’ve had a spell applied to my man sack that makes it and everything within it completely indestructible. So your mother couldn’t destroy my fertility even if she wanted to.” 

“Typical excuse.” One of his kids muttered. “But doesn’t it still hurt?” 

“Oh, it hurts. A lot, even after all this time. But by now, it’s become a great feeling…” Knuckles nearly went into a lustful trance as he recalled all the ways that bat would beat his eggs, much to the confusion of his kids. “Uh… Only from mom, of course.”

“So… It’s fun for you if Mom attacks your bag. But we’re not allowed?” 

Knuckles placed a palm to his forehead with another sigh. “Look, it’s a complicated thing, alright? Let’s just agree that it’s okay for ‘Mommy’ to hit my sack and it’s not okay if you kids do that to each other.” 
“Fine.” 

“If you say so.” 

“Bad answer, but whatever.” 

“This does make me wonder, though… Why do you let Mom attack your balls…?” 

“Oh yeah! I’d love to know how that started!” 

Knuckles smiled with amusement at his children’s curiosity. “Now that is something I can tell you all! Although, it’s a bit of a long story…” 

“Not really.” Spoke the voice of an adult woman. Knuckles and his offspring looked to the direction of those words and saw Rouge the Bat approaching them, whilst breastfeeding two echidna babies that were obviously born very recently, evidenced by their echidna quills having just started to grow. 

Physically, Rouge had more notable changes than Knuckles had the past six years. While his balls and scrote simply got thicker and bluer, Rouge’s tan skin became darker from the constant sun exposure, thanks to Angel Island floating above the clouds. She gained weight in the mid regions from the continuous pregnancies and births, but only by a small margin as the bat relentlessly exercised to keep her slim build. And indeed, the combination of normal exercising and busting Knuckles’ balls gave Rouge more defined muscles in her legs, arms, and chest, with the belly being the only exception due to the chronic pregnancies. Although her abs were no less strong than her male mate’s, owing to the incredible stretch they received when Rouge got gravid. 

All of the echidna children smiled at their mother and enthusiastically greeted her in their own ways, and Knuckles gave his female mate a single nod with a smile. “Heh, how much did you hear of our ‘discussion’?” he asked.

“I heard, and saw, pretty much the whole thing on my way over to you guys.” Rouge adjusted her hands that carried the suckling infants. “Would have arrived sooner if not for these two taking their time getting full on my milk.” The mother bat then turned to Cherry. “So first of all, that was a great punch to the balls, Cherry! Just make sure to do it to balls that don’t belong to any of your brothers.” She then turned to Knuckles. “And you were going to tell them the story of how we got together without me? Hmhm, you’re going to get some lashing in the gems for that.” 

Knux chortled in his throat. “Well, before you do that, would you like to tell them, Mrs. ‘Not Really a Long Story’?” 

Rouge nodded and got up next to Knuckles, then looked to her many kids, who looked back at her with interest. 

"So, it all started about a year before the first of you were born. Your father had been the last living echidna since he himself was born, and by this time he wanted to do something about it before his biological clock started ticking. But in order for him to make new echidnas, he needed a woman to make babies with, and I was his only real option." 

"Now, of course, I love you all and don't regret having any of you in the slightest. But I had never planned on becoming a mom, and the only thing that made me consider repopulating the echidnas for daddy was that my life up to that point was getting boring. But I needed more incentive before I could agree to birth an immense amount of children for him." 

"Wouldn't you know it, though, your daddy had that exact incentive in the form of his balls, which were just perfect in every area. And still are." Knuckles blushed from that assurance. "So I made a deal with your dad that I would breed countless echidnas with him and, in exchange, I got to do whatever I wanted to his jewels. And I happen to have a serious love for hurting the balls." 

Rouge gave Knux's balls a quick kick, to which he groaned while clutching his pearls. "So, that's why I attack his balls all the time, and why he lets me do it no matter what." 

The children all go 'Whoa' with genuine awe. 

"So, it's because Dad let his balls get hurt that we were born to begin with!" 

"Cool!" 

"How brave!" 

"Very romantic!" 

Knuckles smiled as the pain in his balls lessened. "That's right! In sacrificing my balls to your mama, I got the biggest balls of all! And you're all definitely telling this to your children and grandchildren, and make sure they all do the same! I want to make that my legacy!" 

"Sure thing, Dad!" 

"You earned it!" 

"But what about Mommy?"

"Hmhm, you all make sure that I am remembered in our family history, and history overall, about my single handedly birthing the echidnas out of the endangered list!" Rouge turned to Knuckles. "On that note… My postpartum period had ended. And I just started ovulating." 

"Oooohh~!" Knux's permanently erect cock hardened from that news, and his four penile heads reddened with eagerness. "You up for it now…?" 

"Of course!" Rouge shifted her eyes to the babies sucking on her nipples. "Although these two won’t be finishing for a while. I guess the big question is, what position you want to do?” 

“Mm, I’d love to do the mating press. Gives the best feeling and best chance for impregnation!” 

“I mean, I’m always guaranteed to get pregnant no matter what.” Rouge giggled. “But alright! I’m sure these two won’t mind, so long they’re getting their food.” 

Knuckles and Rouge locked lips and the bat woman got onto her back as she and Knux shared a deep and loving kiss. Once she lay flat on her back, the breastfeeding babies having adjusted position for it, Knuckles crawled on top of Rouge and aimed his four-pronged penis at her bat cave. 

The first and second born of Knuckles and Rouge’s brood get grossed out and shield their eyes, knowing what was to come. Their younger siblings, on the other hand, looked at their parent’s mounting with curiosity. The adult echidna then inserted his red rod into the fertile bat, producing delighted moans from each other, and began thrusting. 

“Oooohh, how I’ve missed your quad beast~!” Rouge shouted. 

“Mmmf~! And how I missed your tight tunnel!” 

“Eww! Why do you two have to do this in front of us? Again!” One of the firstborns yelled. 

“It’s like kissing, but more nasty!” One of the second born screamed. 

Rouge glanced over to the children with a gleeful grin. “Oh please! Sex is a beautiful thing! And how you were all born to begin with! You just lack the maturity to appreciate it.” 

“Excuse me if I don’t find having a boys pee pee in a girl’s pee pee pretty to look at!” Rouge Jr. sassed. 

One of the youngest children placed a finger to their lips in intrigue. “What is Daddy doing to Mommy?” 

“Yeah! Why is his birdy inside her giney?”

Knuckles groaned with pleasure. “To make more babies, of course! Which means more siblings for you guys!" 

"Weally? How does that wowk?" 

Knuckles slowed down his thrusting as he pointed to his backsack. "You see, when boys become a man, like I am, their balls start creating stuff that we'll call 'baby seeds'. When a man's 'pee pee' gets excited enough, it squirts out all those baby seeds from the balls. And if a man does that inside a woman's 'giney', those baby seeds enter the eggs within that woman and turn into a baby, which then grows inside the woman's tummy until it's ready to come out. Which you guys have seen before." 

"Wow…!" Most of the youngest uttered in awe. 

"Don't even think of making babies with each other, though!" Rouge yelled. "None of you are the slight bit of age for this, and this is reserved for boyfriends and girlfriends only!" 

Most of the children nodded in acknowledgement, and watched as Knuckles plowed into Rouge at full force and full speed. The red echidna moaned with joy as Rouge’s vaginal walls squeezed his sausage.  And the tan bat shrieked in glee as her mate smashed her pussy with all his weight and strength. All the while, the infants on her breasts sucked extra hard on her nips for the milk within due to having to fight against gravity, getting some good screeches out of Rouge. 

The first and second borns tried to look away for the duration of their parent’s baby making, but it went on for a lengthy time, and they increasingly could not help but peek every so often. And one sight they could not take their eyes off of was that of their father’s balls: the large purple and blue orbs bobbed up and down in a hypnotic rhythm, slapping against Rouge’s plump butt. And in preparation for pumping out the gallons of cum within, the echidna’s testicles grew even larger and its scrote contracted, making the view all the more repulsive to the six and five year old children, yet all the more hard to avert their gaze from. 

Soon enough, a mischievous idea formed in Cherry’s head as she glimpsed at her dad’s nuts and noticed how vulnerable they looked. The girl formed a fist, channeled her super strength whilst charging at her father, and delivered a powerful haymaker to his babymakers. 

Knuckles eyes bulged open and his whole body flinched, halting his thrusting. "GAH!!! Grr…” He resumed pumping into his mate whilst glancing behind himself with anger. “Cherry…! What did I freaking say about hitting the balls…?!" 

"What? You only said we can't hit each other in the privates. But you didn't say we couldn't hit your nuts." 

Knuckles fumed. "As if I need to tell you that you can’t hit your own Dad in the balls!” 

“Oh relax, hun!” Knux’s fuming ceased as he looked back at Rouge. “She does have a point. You never told them to not hit your balls. Besides, it’s clear they really want to harm some private bits, and since your stones are unbreakable…” 

“You’re not seriously thinking what I think you’re thinking, are you? Cause wouldn’t that be… Weird?” 

Rouge giggled. “Knuckie, our relationship as it is, is weird. And don’t think too much about it! They sure won’t. And so long neither of us gets ‘excited’, we’ll be fine.” 

“Err, I guess…” 

“Hear that, kids? You have my permission to go all out on Daddy’s orbs! Punch them, kick’em, smack and yank them! Just don’t bite or let them in your mouth at all! That’s for Mommy only.” 

The echidna children immediately got into a single file line and took turns abusing their dad’s poor balls in all devious ways they could. Thanks to their very young age, the echidna tykes could not hope to match their mother and her female friends in terms of sheer force or technique. But they could lay down the pain nonetheless thanks to the super strength they inherited from their dad, combined with their immature recklessness. 

And so, Knuckles yelped, groaned, and cried out in pain as his own offspring blunted and stretched his echidna makers. Yet the male was not hindered in his babymaking with Rouge, continuing his quick and mighty thrusts, the pleasure of which he tried to focus on to distract from the pain. 

“How ironic! In the process of making new babies, your babymakers are getting beaten on by your already born babies!” Rouge mused. 

“Uurrrggh! Yeah… It’s all sorts of crazy… Anyway, are you nearly at your climax? Cause I sure am…!” 

Indeed, Rouge could feel Knuckles’ four penis tips aching to release his ball’s contents. “Mmm~... Yep…! But don’t cum yet!” Rouge locked her legs around Knuckles’ waist while she directed her attention to the children. “Hey, kids! Would one or two of you like to help us make your new siblings?” 

Knuckles Jr. and Rouge Jr. immediately raise their hands. “We’d like to!” The rest of the echidna kids raised their hands, only to see two of their own had beaten them, and dejectedly lowered their hands. 

“Haha! Alright then, Juniors! Each of you grab hold of one of Daddy’s testicles.” 

The brother and sister went over to behind their father, who began to sweat and strain from the intense mating, and Knuckles Jr. grabbed the right testicle while Rouge Jr. gripped the left. “Testicles grabbed!” They said in unison. 

“Okay! On the count of three, you will be allowed to cum, Knuckie! And you two will squeeze his orbs as flat as you can! Ready…?” 

“Ready!” Knuckles shouted, with a hint of desperation in his voice. The Juniors simply nod to their mother with mischievous smiles. 

“One… Two… Three!” 

The moment ‘three’ was announced, the brother and sister squeezed their dad’s balls with incredible force. And immediately in response, Knuckles released his seed into Rouge, which provoked an orgasm from the bat, and the two moaned aloud together; Knuckles from having his fruits juiced but getting to unload his spunk, and Rouge from having her cavern flooded with Knux’s cum. 

The next few minutes went on with Knuckles pumping out a continuous stream of echidna seed whilst most of his and Rouge’s children cheered at the new life that would come from this. And much life would ensue from this breeding, as many of Knuckles’ sperm made their way to Rouge’s ovaries, wherein plenty of her eggs awaited penetration...
