Knuckles' Jewels- Swelling Belly and Balls (Chapter 5)
About three weeks had passed since Knuckles and Rouge's fateful night. Both of them went back to their normal routines before all this ballbusting started, which just happened to be exercising. Rouge was doing plenty of acrobatics, mainly jumping and hanging from uneven bars. Knuckles, however, was more of a purist, doing crunches and push-ups and other self exercises. They were so busy exercising that Rouge never hit Knuckles’ jewels once during that time. One would think it was just because she forgot, but the bat knew that the fear of when it might start again would certainly arouse her rojo husband a whole lot more.
And indeed it did, as after some time, Knuckles was both excited and dreading the day when Rouge would leave the bathroom with that devilish smile on her face, letting him know that the pregnancy was about to begin. He would be excited to finally repopulate his species but dreaded at now how painful Rouge was going to be to his hanging berries. And when that frightful day came, both Knuckles and his orbs never saw it coming.
Knuckles was busy that day doing sit-ups, out in his usual training spot outdoors, and did not see his wife silently walk up to him from out of his view. Once he saw her, he was getting the panty shot most men would dream of, getting to see a swollen pussy right in the central vision of his face. His member, which had never gotten flaccid even after that tremendous sex, hardened ever more. He never got to see her face, which showed she was calculating her first move.
Rouge gave a soft murr from above. “Hello, sexy. You look excited to see me.”
Knux chuckled. “Why wouldn’t I, when I get to see that sexy second pair of lips you got?”
“Wanna get a closer look?” Rouge gives a soft chuckle back, knowing her true intent.
Knux’s pole stiffened up more. “Oh boy, would I!”
Rouge purred. “Here you go.” She squatted onto his face, getting his snout right in her vagina.
The echidna was enchanted by the erotic scent of her bat tunnel, which was releasing new pheromones unknown to him. He thought it smelled the same as before, and was about to lick it when Rouge brought her man back to the painful reality.
Knuckles gave a loud groan as he felt a cast-iron skillet slam him square in the balls with enough force to squish them out like a pancake for a long moment before the pan bounced back away, his balls reforming back to normal with groove marks of the pan. It was only a moment, but the pain stung for a long minute before it subsided and the bat got up.
“OW!!!!” He groaned out.
Rouge smirked. “Ooop, sorry. Thought I was making eggs sunny side up.”
“More like scrambled! Youch!” He rubbed his nuts to try to console his manhood. “What was that for?!” Knuckles only needed to see the mischievous smirk the bat had plastered on her face, knowing full well now what it meant. “I-It’s starting?!”
Rouge nodded. “My ovulation cycle this week had passed, and I didn’t get my period. So the buns are officially starting to bake.”
Knuckles’ face was a mix of joy and fear. “Y-yay…!”
Rouge snickered. “All the pains and pleasures of the growing babies in my womb are going to be so interesting to feel!” She takes a long stare at Knux, with an evil grin. “And you better be there when I call you. Because those pregnancy annoyances will happen, and I want to punish your man berries for each and every single one!” Knuckles winced as Rouge dug one of her fingernails into his right testicle. “And since they’re indestructible, I can start punishing them in many new ways!”
The red echidna groaned, rubbing his balls. “Oh no…”
Rouge comes back around to her love, and strokes the length of his shaft. “If you stay a good boy, though, you’ll be rewarded quite handsomely, love.” She places another hand under his blue and purple sack. “And you’ll be getting plenty of release this time, now that your balls are colored to my liking.” 
“Well… That’s a silver lining.” Knux grinned. 
“At least, you’ll be getting plenty of release before the eighth to ninth month. Around those times, preggor sex could start labor too early. So instead I’ll make sure your goods remain blue and purple.” 
Knuckles made an unamused face, but accepted Rouge’s reasoning, and then the two resumed their activities that day: Knux trying to endure the burning agony on his scrotum in the midst of exercising. And so the two waited for the pregnancy to advance, specifically with a more obvious sign that Knuckles hoped would not bring harm to his balls. Unfortunately for him, the worst had yet to come.
----------------
Anyone with a lick of knowledge on pregnancy knew that the first obvious symptom of pregnancy was the ever so dreaded morning sickness. And indeed, when Rouge’s morning sickness first manifested four weeks later, the nausea hit her like a truck. 
“Uuuuuggggghhhh…” Rouge groaned, as she got up from her sleep with a stretch. 
“Mm… What’s wrong?” Knuckles drowsily asked, not fully awakened yet. “You don’t normally get up this early…” 
The bat pressed a palm to her belly, whilst keeping her half-awake head steady. “I’m feeling seriously sick to my stomach…” Right after finishing that sentence, Rouge covered her lips as she felt the contents of said stomach rush up her throat. 
Knuckles immediately snapped out of his drowsiness in response and sat up in bed, facing Rouge. “What?! The babies are okay, are they?!” The naked bat lady could not answer her mate’s question as she hurriedly tossed off her bed covers and rushed outside the house. “Wait! Rouge!” The echidna tossed aside his sheets in turn and gave chase. 
After going through the front door, Rouge beelined for one of the many trees outside their home, got on all fours, and heaved onto the roots of the unfortunate tree. Knuckles caught up to his tan wife soon after. 
“Holy crap, Rouge! Are you okay?! Are the babies safe?!” 
Once her mouth became unoccupied, the nude mother-to-be still said nothing. But she did hear her panicked mate’s questions, and reared her right leg in response. Within an instant, Rouge shot her heel up into Knux’s testicles at the speed of a bullet. 
The red echidna felt all the air leave his lungs, pushed his hands to his belly, and came down to his knees as his precious seed makers were crushed flat against the bottom of his pelvis by the bat’s powerful foot. The pain was so overwhelming that Knuckles felt he was about to throw up as well, and he very nearly did. But he had the force of will and body to keep his stomach’s contents within. 
“Aaaaaagggghhhhhh… What the hell was that for…?” Tears leaked out of his eyes as Knux tried to look at Rouge, who turned her head to look back at him. 
“For the morning sickness, you Knucklehead… Don’t you know that’s one of the first signs of pregnancy…?” Rouge spoke with a hint of fury, offended that Knuckles seemed more concerned about the welfare of embryos instead of herself. Though her then angered expression softened as she reminded herself right after what those embryos meant for the last living echidna… 
“Uuuurggghh… No… I don’t know anything about pregnancy… Except from the little you had told me about it…” The male took a deep breath and exhaled to handle the pain, whilst Rouge kept pressing her heel hard against his stones. “So… The babies aren’t hurt or anything…?” 
Rouge chuckled a bit. “No. The babies are perfectly fine. Morning sickness actually exists to help keep them safe from potential poison.” The bat was about to laugh some more when another gagging feeling forced her to cover her mouth. “Sure is a freaking inconvenience to me though…” 
Knuckles squeezed his eyes shut from Rouge digging her heel deeper into his balls, the organs in a completely flat state only possible through this indestructibility spell. “Uuuuuuckk! Sorry…!” 
“Don’t be sorry! Just suffer with me!” 
The bat could no longer hold back her illness and let it loose onto the ground once more. And as she did that, she removed her heel from Knux’s jewels and began slamming it back up repeatedly; this time striking one male orb at a time to make those testicles feel the most pain. Knuckles gasped and grunted with each strike his puking mate dealt to his goods, and soon his belly area ached as Rouge’s did. 
And that would go on to be the routine for the echidna’s melons each bout of morning sickness: Rouge making Knuckles’ belly ache as hers did through the most intense testicular torment. Kicking was the most preferred, being Rouge’s most devastating form of attack, and the blunt trauma having best chance to send up pain to his stomach. But squeezing and punching did the job just fine. 
Not long after the morning sickness arrived, the rest of the first trimester symptoms made themselves present: starting with tender and swollen breasts. A symptom Rouge did not actually mind too much, as she appreciated her big ladies getting even bigger and remaining that way for the rest of the pregnancy. But tenderness on extra large tits did not combo well, as the weight made them ache even more than usual. And the huge mammary bat did not like that one bit. 
So in retaliation, Rouge would break out an extra big set of ball weights and clamp them to Knuckles’ nuts, and then beat on them relentlessly until they were tenderized as much as her breasts felt. Suffice to say, Knuckles could no longer let his boys hang freely without agonizing discomfort. 
Then came the mood swings, which hit Rouge almost as hard as she kicked his nuts. Anger was the worst out of all of them, as she could be busy doing something or just talking to Knuckles and then be hit with an anger spell. Knux could see the fires burning in her eyes and no amount of distance or protection would save him from suffering a devastating attack to his balls. The bat would go all out with kicks, punches, elbow jabs and knee smacks, and she never retracted her claws during any of this. If it weren’t for the invulnerability his nuts had, they would be utterly destroyed at these times. Sometimes she would even attack with whatever she had in hand like pens, pans, baseball bats or whatever is lying around nearby, and those delivered sharp and blunt pain and sometimes even squishing his nuts into his crotch. Lucky for him that anger was the shortest lasting, as just hearing him shout and groan would satisfy the bat’s painful needs.
The echidna was dreadful when his batgirl would start crying all of a sudden. She got very tearful and forlorn when the sadness hit, and she’d stay in bed, sobbing. He was worried something was wrong with the babies the first few times, but learned after a while it was just another mood swing and the babies were alright. He eventually was able to come in and console her, usually by letting him crush his nuts in her hands like stress balls until it subsided.
On the polar opposite, Rouge would sometimes start smiling and chuckling out of nowhere. He, at first, thought it meant she was about to hit him in the nuts really hard, but instead she got on top of him and had a quickie with Knux right then and there. Indeed, Rouge became quite the nymph whenever her mood swung to joy, and would immediately seek out Knuckles to fill her love cave. However, Rouge would get so giddy that she would bust the echidna’s gems in bouts of hype, such as slapping them repeatedly to get Knuckles to speed up his thrusting. Despite that, though, Knux favored Rouge’s ‘happy phase’ most of all the moods.
Perhaps a quieter, more intimate moment with Rouge would come when she would get tired all of a sudden, yet another pregnancy symptom. Her wings would stop flapping and she’d hunch over, feeling very tired and placated, usually letting Knuckles’ jewels off the hook from whatever she was doing. Being quite the gentleman, he would carry her over to their soft and comfy bed and cuddle up together to take a nice, long nap. She would be quite clingy in her sleep, sometimes digging her claws into his nuts that she loved to hold in her hands. He would groan from the pain and moan from pleasure, and it was definitely the most gentle hold she had on his nuts during the whole time.
Knuckles’ happiest memories during the pregnancy came when the bat started getting the cravings all ladies got when heavy with child. She had the usual crazy ones like a peanut butter covered pickle, but the most strangest of them all was his quite literal nuts. She would eye his berries with an intense stare, licking her lips, then dive right in with them in her mouth. Her suction could rival a vacuum with how strong she held on, and it was painful if she had been smashing his nuts beforehand. That pain would change to pleasure, making him give a long moan with just how good it was. He was sure the bat was taking in a lot of his sweaty ball musk, which she must have enjoyed, since she sucked harder the longer they were in her mouth. When she was satisfied, she would let them go with a hearty flop, panting and happily murring. And usually after, she would be back to her usual self, leaving Knux back to the painful truth of his wife.
All that went on for three entire months, which made the two months of ballbusting and blueing Knuckles endured appear more generous. But nonetheless, both he and Rouge suffered as the negative symptoms struck her. But on the arrival of the fourth month, almost all those symptoms went away... 
The morning sickness was all but gone, Rouge’s breasts had settled their newly increased size without the tenderness, and the fatigue was no longer as extreme. Only the mood swings remained, but they were the least bad of those symptoms. It seemed as though the echidna and bat’s luck had changed with the second trimester. 
Alas, it was too good to be true, as the second trimester came with its own symptoms that, while not nearly as bad as the first, were enough to get on Rouge’s nerves… 
To start, the second trimester was the point at which Rouge’s baby bump really started to show. Her belly had gotten increasingly rounded over the course of the three months, but did not appear big nor feel too heavy. But with the fourth month, it was blatant that Rouge was preggors with many, and she felt the weight gain. And so, the bat stayed true to her word and made those echida-cles swell alongside her belly via intensifying her ballbusting. 
Knuckles had thought the busting Rouge delivered for the other pregnancy annoyances were torture, but they were child’s play compared to the torment she inflicted when trying to make his rounded treasures inflate. Had it not been for the indestructibility spell placed onto his reproductive organs, Knuckles would have been less of rendered infertile ten times over. And indeed, those male fruit expanded a great deal from the agony that tan bat delivered, to compensate for her own expanded mid-section. Soon enough, Knuckles’ nuts enlarged to an even bigger size than from the two months of ballbusting before impregnation, and took on a much darker color, much to the she-bat’s delight. 
And as the pregnancy advanced, making Rouge’s womb stretch further and further, the tan-skinned bat would punish those man orbs of her mate’s by resting her increasingly large baby belly on top of those spheres: crushing them with the weight of the kin they seeded within her. Knuckles would have been laughing about the cruel irony had it not resulted in the greatest of pain for him.
As the weight increased, it started to put a strain on her lower abdomen with a lot of aches and pains, enough so that she had to sit around when it got to be too much. She, of course, called her red echidna right on over to sit behind him and start massaging her body. He lovingly obliged with shoulder rubs, side rubs, back massages and belly rubbings. The bat did love this generous love and affection, so to reward him, she would grab his orbs tightly and give them a nice groping, which hurt from all the pain but made him moan in pleasure, and making his dick get hard along the groove of her back. She laid her back on it, treating it like it was a soft chair cushion. Knuckles had to make sure he was massaging the right areas, as one wrong move meant getting a hard elbowing to his nuts, making him groan.
Rouge was never amused when her legs cramped up during these months, and Knuckles thought it meant he was in the clear during those times. He was wrong, as the bat girl would order him to be her ottoman to kick her feet up on his balls. As she would relax, she gleefully dug the back of her feet into Knuckles’ dark marbles, finding them quite comfortable.
The third trimester soon rolls in around six months and her belly was expanding so much that it looked like someone overinflated a beach beach ball in her womb. But that pressure and the size was nothing compared to the feelings of the squirming children in her. As expected from a kick trained bat and a punch trained echidna, it was feeling like a MMA free for all was going on, with plenty of feet and fists hitting around all sides. Of course, this meant going even harder on Knuckles’ baby factories and sometimes, even those kids got in on the action. If her belly was close enough to his nutsack, he was forced to feel the constant fighting and turmoil going on, with painful moans escaping from him, satisfying the bat.
Then came the constipation and increased urination, which would occur separately or both at once. Either way, these symptoms frustrated Rouge a great deal and she took out those frustrations on Knuckles’ balls by having him accompany her outdoors and allow those babymakers to be crushed underfoot as the bat squatted. Whether it was number one or number two, Knuckles had to endure a world of agony. 
With the constipation, Knuckles had to be with Rouge for long periods of time, her foot or both feet pressed on top of his echidna tenders, while she tried to relieve herself. And should that relief end up not coming, which was most of the time, she would stomp down hard on Knux’s stones in rage and leave in a huff whilst the echidna cradled his crushed goods with tearful eyes. And then soon after, the urge to dump would return… 
For the increased peeing, while they lasted a lot less time, they were a lot more frequent. If she didn’t piss at all, or if it burned as it came out, she made sure to show her discomfort with a constant and painful squish on his nuggets for as long as the feeling lasted, which sometimes went on for minutes. On the rare occasions it was a normal piss, she would instead give a relief to her man’s balls… With a golden shower spraying all over them. It did give a small sting on his beaten up balls, but the warm fluid did feel nice on his sack. But, of course, she would bring him back to reality with a swift kick to his nuts and make him groan and spit out what was in his mouth.
A curious sign of Rouge being close to giving birth came when her bat nipples started to lactate. It did surprise both to see the milk start dripping down her naked body. Perhaps it was the hormones or leaky nips, but Rouge would allow her husband to lick up the bat cream out of pity for him. He indulged with grateful licking, cleaning up the mess. Such a gentle-echidna, he even gave those bat tiddies a few test sucks, just to make sure they were working right. The bat never complained, since it definitely made her moan and like the sensation her husband was doing. 
--------------
But not all of Rouge’s ballbustings in the nine months were done in immediate retribution for the burdens of pregnancy. There were many other methods of testicle abusing the bat fantasized about doing to Knuckles since the beginning, but were too extreme for her to do, lest she cut short the echidna’s ability to procreate. But now that Knuckles’ testicles were indestructible, Rouge could make those fantasies into reality… 
The first of such extreme testicle tortures was the good old ‘heel panel’: a flat, square board with a hole in the center, big enough for Knuckles’ cock and balls to fit through. Rouge took great amusement from Knuckles’ confusion when she first administered the heel panel to his goods and then commanded him to lie on his back. That echidna just knew something dreadful was going to happen and was almost relieved when that doubt went away the moment Rouge got onto the board and stomped her heels onto his balls. 
Previously, Knuckles hardly had to worry about Rouge stomping on his fruit. The rare times she did stomp, she held it way back so as to not reduce his balls to paste. But she could go all out this time, and Knuckles fell into a pain-induced daze as that bat danced on his jewels with a face of glee. In addition to the heel stomps, Rouge would stand on one testicle with both feet to put all her weight on them, which only became more effective the more her pregnancy advanced. And there was the pointed high heels, which delivered the most piercing agony Knuckles had ever received down there… 
The next form of torture Rouge had become allowed to do was to use her sharp bat teeth on that echidna’s fruits; to bite and chew on them like the giant red gumballs that they were. Knuckles could never forget the very first time Rouge ‘feasted’ on his orbs… She started with mere nibbling, which was incredibly uncomfortable to feel on one’s loin spheres, but otherwise nothing too bad. The moment those fangs of hers dug into his testes, however, Knuckles could not stop howling in agony for the whole duration of the chomping. 
Then there was electrocution, a form of ballbusting that definitely could not be used without wiping out every single sperm in Knux’s loins and permanently keep more from being created, but was no longer a concern with Tikal’s enchantment. And fortunately for Rouge, she had a constant source of electric torture in the form of her taser: something she never really had a use for and only kept around due to it being a mandatory government issued equipment. Knuckles had to really steel his nerves whenever Rouge busted out that shocker, and it was definitely the most agonizing form of pain dealt to his stones yet; his testicles would vibrate violently from the taser’s volts and his scrotum could not decide if it wanted to tighten or expand in response to the very unusual feeling. 
Up next came whipping, which Rouge could have administered to those jewels in a safe manner. But being a lot sharper than purely blunt force made whipping just a bit too risky to do without castrating. But at last, that bat could put her riding crop to good use and whipped that echidna’s cream makers into shape. She would delight in the sight of Knux’s sack spasming from the sharp strike of the riding crop and the shaved side of his scrote blaring red.
A big moment Knuckles would never forget was the first time he experienced the ‘speed bag platform’. It was something Rouge had built in her own little spot in Angel Island, and had done so in the middle stages of her pregnancy. Upon finishing it, she brought Knuckles to it and had him sit on top, with his balls going through the hole at the top. The echidna sighed with dread as he did so, and the moment he had sat down, his male orbs dangling in front of Rouge, that bat popped her knuckles and went to town on them; striking them with quick yet powerful jabs and haymakers. 
Knux threw his head back and gritted his teeth from his bountiful sack getting punched and swung around, smacking against the underside of the platform he sat atop. While Rouge’s kicks were far more devastating than her fists, she really knew how to pack a punch. The echidna figured she had to have picked them up from himself from all their past encounters as rivals. And no doubt, this particular ballbusting was the gravid bat’s payback for all those blows he landed on her, especially in the breasts. Rouge smirked from her mate’s writhing and, after getting him hanging his tongue out in a daze, the heavily pregnant bat reared her fist and then delivered a bone-shattering uppercut to those testes, crushing them up against Knuckles’ pelvis. And indeed, Knux’s pelvis would have shattered had his massive fruit not absorbed most of the impact of that bat’s punch. 
On a related note, another unique form of busting Rouge performed was using Knuckles testicles as makeshift barbells; grabbing the very bottom of his scrotum with a tight grip and weightlifting with them. Thanks to their innate size combined with the swelling, those echid-nads were actually quite hefty. But the real exercise was from the stretching: pulling that sack toward herself against the resistance. 
And the last, but certainly not least, extreme ballbusting the pregnant Rouge administered to that red echidna was candle waxing; that is, lighting a candle and having the wax drip onto his sack. Since Knux got to plant his seed into her, and she was months away from giving birth, Rouge did not have to worry about killing any of his swimmers from the heat: by the time she could conceive again, the sperm in his sack will long since have replenished. And so, the bat was able to revel in burning the echidna stones with hot candle wax. 
---------------------------
On the beginning of the eighth month, Rouge was pleasuring herself with some ballbusting porn… While kicking the everloving hell out of Knuckles’ balls. 
“Agh!” The male screamed, tears flooding his eyes and legs quivering. “Come on, Rouge! Aren’t you tired out from kicking my balls this fast and hard?!” 
The heavily pregnant bat shot another powerful kick to the echid-nads, making their owner bellow out in agony. “No way.” She answered with a smile. “Torturing your balls energizes me~! Besides, I gotta keep up with the girls in this video.” 
The video in question is a porno of a group of six women kicking a lone man in the testicles. The male is tied standing up with his arms and legs spread far to the sides, leaving his man fruit at the mercy of the six girls, who kick at them one at a time at a rapid pace. For the unfortunate boy, it’s like getting mashed in the loins within milliseconds of each mashing. And Rouge was trying to replicate exactly that to Knuckles whilst intensely massaging her enlarged and reddened clitoris, which Knuckles started at with great desire. 
“Urgh… Fair enough... But why masturbate to porn when you got me…? You’ve bashed my balls countless times while I was ball deep in you...” He grunted painfully in between words as Rouge continued bashing her foot into his orbs.
“Why do most men fap to porn when they have a wife?” She asked with a teasing smile, which Knux found himself unable to respond to. “And don’t forget, I’m in the late term now. Just a drop of your pre-cum could start the labor early, and we can’t have that happen.” 
The bruised-balled echidna sighed. “Right…” He then turned his attention to the porn video and watched it alongside Rouge. The man winced from each kick that guy in the porn received. And yet, Knuckles could not help but be attracted to the nude women kicking the poor male. None of the women were a match for Rouge in the overall sexy department, but they nonetheless had great breasts and hips for breeding. And Rouge could tell he was getting attracted from how pronounced his erection became. 
“Enjoy the show while you can, hun.” She said to herself with a devilish grin. “This is a preview of what’s to come for you soon…”
