Knuckles’ Jewels- Busting Memories (Chapter 3)
“Hmm…” 
Knuckles looked at Rouge with anxious eyes as she held his orbs in her hand and studied them with a squint. The bat was holding the echidna’s jewels with a mild yet firm grip, keeping the scrote tight to analyze the skin in detail. However, Knux could hardly resist the urge to groan from this and hoped she would release that grip quick. 
“Okay!” Rouge announced, “Your balls look completely purple’d!” She released her hold on the mansack, to which Knuckles gasped and sighed with relief. “...From the front, that is…” The bat pinched the bottom of the echidna’s scrotum and lifted them upwards to look at their back from underneath “Let’s see if the back is hiding anything!” 
“GAAH!” screamed Knuckles, having not expected this action, and could not resist the pained response. 
“Oh hush!” Rouge said with a teasing smile, “I’m not even touching your balls with a tight grip.”
“Urgh…! Well after subjecting my balls and scrote to all sorts of pain and keeping them pent up for two entire months, any sort of touch to them hurts like hell!”
“Hmhm! It would probably help if ‘Mr. Quadhead’ would stop being erect, huh?” The bat indicating to the echidna’s prominent four-headed member standing tall and strong, and then gave the organ a playful flick to one of the heads, which made it stiffen ever stronger. 
Knuckles sighed “Yeah. Whole crotch area gets sensitive during an erection. But can’t blame the poor guy, after all the teasing you gave him!” 
“Ha! And he’s definitely very eager to get to penetrating my pussy, now that the fateful day has arrived! But first, I have to make sure today is that fateful day…”
Indeed, two months had passed since the very first ballbusting session the two shared, and with it they would finally begin the repopulation effort for the echidna species. Knuckles could hardly believe that those two months had arrived already: while for Rouge the two months passed as usual, for Knuckles the passage felt like a lifetime. Which was a given, considering the entire two months were spent with his testicles receiving all sorts of punishment from Rouge and actively kept on the verge of orgasm but never allowed to release. With both those going on at once, any man’s sense of time would slow to a crawl. 
Just as the bat had hoped, Knuckles entire sack had turned purple from the two-months worth of abuse and denial and doubled in size from swelling. At first glance, one would be forgiven for thinking Knuckles had huge eggplants dangling between his legs, especially as they shined like the vegetable does. A thought that Knuckles was not happy about, as he missed the natural red color of his precious stones. But he had two months to get used to this new status quo for his gems, and being completely purple’d was a better look for them than the awkward ‘purple on the bottom, red on the top’ they appeared as during the transition. 
And though his dick did not undergo such a change, the four heads that made up the tip of his massive penis had turned red after months of intense stimulation from Rouge, and the echidna rod had seemingly become permanently erect as it had not returned to flaccid-ness after the first month of orgasm denial. Which, in turn, only made the rest of the ballbusting sessions all the more overwhelming to endure thanks to the increased sensitivity erections bring to the balls. At this moment, Knuckles wondered if his dick would ever go flaccid even after finally getting release. 
After a few minutes of checking the whole back of Knux’s sack, Rouge pulled her head up from underneath the echidna with a sincere smile. “Great news, Knuckie!” The bat released her pinched grip of the Rad Red’s bottom scrotum, which allowed the testes to swing back down to normal position (and earned a pained ‘Gah!’ from their owner). She then stood upright “Your balls are entirely purple, from top to bottom! Not a spot of red left!”
Knuckles formed a massive smile and his cock seemed to grow taller at this exclamation from the bat “So that means-?!” 
“Yep!” the bat nodded, “You’re officially allowed to have vaginal sex with me!” Rouge placed both her hands to her crotch and moved them up and down against her exposed tan pussy “And as luck would have it, my ovulation starts today! So we can get your purple spunk to fertilize my countless eggs right away…” Knux could not help but drool at the thought of his swimmers penetrating into Rouge’s eggs and become their first brood. But then Rouge raised a pointer finger upward, a gesture Knuckles long since got familiar with that meant inconvenient news for him, and Rouge’s cheerful expression turned to a sheepish one, knowing that Knux was not going to like it. “But first…” 
The red echidna sighed with an exhausted tone “What is it now? You want my dick to turn completely red too?” 
“No!” Rouge giggled with a sweatdrop, “Your dick is more than good as is! I just decided that, since the purple from your balls is because of the red fur on top of the now blue skin… I’d like to remove all the fur from one side of your sack, so I get both purple and blue balls.” 
“Oh…! That’s it?” 
The white furred, tan skinned bat nodded with her wrists to her bare hips “Mhm! Just sit back and relax on the bed while I get the waxing equipment real quick.”
Knux’s eyes bulged open “Waxing?! You can’t be serious!”
“What? It’s an actual thing in many waxing parlors. And plenty of men voluntarily choose it to get smooth and clear balls.” The bat narrows her eyes and makes a devious grin “Although, I’ll break out the razor and cream if you prefer that…” 
Knuckles’ pupils shrunk and he tighten his lips “...Actually, waxing sounds good…” 
The bat winked to the red male and left for her waxing materials. After she exited the bedroom, Knuckles fell onto the bed on his back. 
“Man… Right when I think she’s run out of new ways to bust my balls, she thinks up one right away... “ The echidna spread out his arms and legs onto the bed and made sure to let his pulsing orbs rest on the comforting sheets and mattress. “Although, if testicle waxing is a regular practice, then this can’t be any worse than all the previous methods Rouge did to bust my junk…” 
Knuckles gazed up at the ceiling and he began to call the most brutal hits he received in the past two months. 
--------------------------------------------------------------------------------------------------------------------------------
The first bustings that came to the echidna’s mind were the very first sessions of certain methods that had since become conventional for the spiny anteater and bat; ball punching and slapping, ball pulling, and ball squeezing. Knux could remember the words he and Rouge exchanged as if they happened just a few days ago… 
“Okay, since I used my feet to strike your gems for the first session, I’m going to use my hands for the second! I’m sure you’ll appreciate that, ‘Mr. Knuckle Sandwich’.”
“Well, I’m not at all used to taking a punch below the belly. Nor have I ever taken or given punches in the crotch. But I do appreciate not getting low blows from your most powerful limbs.” 
Rouge laughed with a palm over her mouth. “You’re sure as hell going to get used to getting punched in the nuts after these two months! And don’t underestimate your opponents, Knucklehead!” Rouge held up her fists with her knuckles pronounced. “My fists may not be as powerful as my kicks, and nowhere near comparable to your own. But they can still deliver a beating. After all, I’m a trained agent of GUN: they wouldn’t allow for me to skimp out on my punching capability.” 
“Ah! Right…” 
The nude, fit built bat tightened her fists. “Now then, as with the first session: spread your legs nice and wide, keep both hands behind your head, and keep yourself standing.” 
Knux wearily nodded and assumed the described position. The very moment his legs got wide and he locked his hands together behind the head, Rouge crouched down, reared back her right arm, and then struck the echidna’s stones with a fast punch. Knuckles yelped as his balls swung backwards from the force and slapped the underside of his buttcheeks. And just as they swung back down to normal position, the cum tanks received another quick punch from Rouge’s left. 
From then on, Knuckles’ memory of that session became a blur as he became too overwhelmed from Rouge using his baby makers as a speedbag to register much of the event. He seriously underestimated Rouge’s ability to punch, and the echidna could only grimace at how she would punish him if he had broken a rule during that session, given how painful the punches already were. And once she was done with making punches, Rouge switched over to slapping the spunk jugs with her palms and backhand with enough power to leave handprints that lasted the rest of the day.
Yet, at the same time, Knux could not help but feel a new sense of admiration for the bat after the fact. After all, being someone who fights primarily with punches, Knuckles was nothing short of impressed with Rouge’s techniques and level of control with her punches; using a variety of punching moves that not even most of his other friends could perform and pulling off those moves with just enough force to deliver intense harm while not rupturing the echidna’s reproductive goods. Had he not been dazed from the agony, the red male would have complimented the bat’s punches throughout the session, but such words had to wait for after the session. 
The Knuckles’ memory then moved onto the first ball stretching session, which occurred the very next day after the punching and slapping. He recalled Rouge’s words that signalled the beginning of that session… 
“Your balls hang very low, Knuckie! But let’s see if I can make them hang even lower!” 
Right after getting into the widened stance, as per the orders, the tan bat grabbed Knux’s spermatic chords and pulled down on them as if they were the ropes to ring a church bell. Of course, pulling down on those balls did elicit a loud noise from the echidna, and he struggled throughout that session to keep himself standing as the athletically built nudist stretched his nuts downward. 
Rouge, of course, was being careful not to pull too hard, lest she literally rip his balls off. But she was exerting just enough pressure to the chords that Knuckles’ protective instinct went into overdrive and the foolish echidna unconsciously made the bat release her grip. Knux remembered Rouge’s reaction, and that of his own, crystal clear: her eyes fully opened in surprise and a round mouth, then her brows furrowed and she formed an annoyed scowl. And Knuckles himself sweated up a storm with blank eyes. 
“Hmph! It’s one thing to shield your busted goods from my sight. But to force me away from busting them...?” 
“I-I’m so sorry Rouge! I didn’t mean to do that! No joke, my body did that on its own! You have to believe me!” 
Rouge appeared all set to castrate the echidna right then and there, at least from his perspective. But much to Knuckles’ relief, she breathed a calm breath and her expression changed to a more understanding look. 
“Right! Yes. Your body is hardwired to protect the balls at all costs. Wasn’t consciously you, but your body’s instinct.” The bat lady turned around and walked over to a box filled with rope. “However, I have to punish you all the same. And this is sure to make your instincts think twice about stopping me from stretching your sack.” 
Knux gulped, and next thing he knew, he was bound by the hands and feet again. This time, though, he was made to lie on his back and his hands and feet were tied together. The echidna felt like he was a freshly captured little animal being prepared to be cooked. And given the circumstance, he might as well have been as he looked at Rouge approach his very vulnerable balls that draped over his curvy butt. 
“Since pulling down on your stones was apparently too much for your body, I wonder how it’ll take to me pulling them up!” 
With a sinister smile, the smooth skinned bat gripped the spiny anteater’s fruit and pulled them upward. Knuckles full-on screeched as Rouge lifted his man spheres up into the air, stretching his chords to just below their absolute limit, and he could not recall the event in detail beyond that point from the intense pain. Best he could recall was how his entire body shook vigorously to try and remove Rouge’s binds, and at one point he sincerely felt that Rouge managed to lift his behind into the air from pulling his balls up. The spike-fisted man was just glad his boys remained intact after that… 
And then the first ball squeezing session… Knuckles grimaced as he could barely bring himself to remember how that went, it was that intense. As much as he could recall, that session started with Rouge squeezing both his testicles with just one hand (an impressive task, given their individual sizes), and used just enough pressure to not pop them. But then, on a whim, she clapped the sides of both orbs with both her hands, to which Knux’s whole body flinched, and squeezed the male seeds together. 
After having her fun with that technique, Rouge went on to squeeze each testicle within each of her hands, making the individual nuts feel the full force of the bat’s individual hands. At that point, Knuckles screamed a mighty high pitched wail from the agony Rouge was putting his cum factories through. And yet, that wasn’t the worst form of squeezing Rouge could inflict, as after a good few minutes of that, Rouge had Knuckles lie on his back and then lifted her right foot high in the air above his balls. 
Knux could only mentally brace himself and shut his eyes tight when Rouge brought that foot down onto his sack, then squeezed on them as if she were pressing down on a car’s pedals. The crimson echidna screamed at an even louder volume and his arms and legs twitched, responding to the overwhelming pressure the balls were undergoing, but actively prevented by Knuckles to prevent yet another punishment: an effort that, thankfully for Knux, proved successful. But all the same, the first and all other times Rouge crushed his testes with her feet were the worst pain imaginable for him to bare, with the exception of the punishments. 
After the initial sessions of the ‘kicking, punching/slapping, stretching, and squeezing’ quadfecta, the next sessions that came to Knuckles’ mind were ones that were the ones that involved toys; ballbusting toys. And unsurprisingly, Rouge had bought one of every type the moment she and Knuckles began to move in together. 
In order to help ease Knuckles in the use of her testicular torture devices, which could be a horrifying experience for newcomer males of ballbusting, Rouge started with the mildest ballbusting tool and worked up to the most hardcore. As such, the first ballbusting device to be used on Knux was the ball weight. 
A thick metal ring, the ball weight was to be worn right on top of the testicles, and stretches the scrotum that it encircles by weighing down the stones they hold. Wasn’t the most pleasant feeling for the echidna, but was certainly the most preferable to all the other methods. 
Of course, to keep the ball weight a valid ballbusting session, Rouge had Knuckles lift his balls up while wearing the weight, doing some literal weightlifting for the reproductive ovals. Knux never minded that part, though, for he’s more than used to lifting heavy material. But for whenever he fails to lift the balls up a certain height, let them down to slow, or anything that didn’t impress Rouge, she would motivate him to do better by hitting his balls: flicks, slaps, punches, and even soft bites. 
It went without saying that the Red Rad quickly learned to master the art of ‘testicle weight lifting’ to avoid such penalties. But Rouge would then add another ball weight to the then newly lengthened scrote to make things challenging again, and thus provide more mistakes for her to punish… But all the same, this was a ballbusting session Knuckles could admit to enjoying. Helped that it did provide genuine exercise, and both his cords and balls were both stronger, healthier, and bigger. 
“You see! After the second month is up, you’ll be pumping out gallons more baby batter than you would’ve before we moved in together.” 
The second ballbusting toy the crimson mammal dealt with was the ball stretcher, which is like the ball weights but made of leather instead of metal and stretches the scrotum by pushing down on the testicles while wrapped above them rather than weighing them down. In comparison, the ball stretcher by itself was preferable to the ball weights since light leather felt better for the male fruit than heavy metal. And the stretching was not only the least uncomfortable, compared to the weights and Rouge’s own pulling, but its effect got minimized over the weeks as the scrote became more lengthy than the ball stretcher itself. 
However, there was one caveat to the ball stretcher that made it less desirable than the ball weights; this particular stretcher was designed with a small ring for a leash to be attached to, and a leash came with the device. And indeed, the true ‘star’ of those sessions was not the leather ball stretcher but the ball leash, the stretcher being nothing more than a collar for the echidna tenders. 
Of course, the ball leash itself was nothing too bad for the echidna. Having such a thing done to one’s manhood was embarrassing for sure, but at least didn’t add extra pain or anything. The ball leash sessions, on the other hand, were what made the toy less desirable than the ball weights, as the sessions comprised of him and Rouge hiking around Angel Island with the leash attached to his man goods. In other words, the ball leash sessions were the bat ‘dog walking’ Knux. 
That alone was overbearingly humiliating to experience, and the only thing that kept Knuckles from dying of outright embarrassment was Angel Island lacking any other people aside from Tikal, whom Rouge took measures to avoid during the leash sessions. As much as she liked to mess with Knux, the mischievous bat did still care for his well-being and would not dare go as far as to let one of his close friends see him in such a demeaning fashion. 
Though Knuckles was thankful for that, he would still feel immense humiliation as there were still many intelligent witnesses to their activity all around Angel Island in the form of the Critters, Chao, and Wisps. The spiny anteater was just fortunate that those three groups mostly had child-like innocence and the mindset of normal animals, so even those who understood the whole ‘leashed testicles’ deal didn’t really care: as far as they were concerned, it was just some form of mating activity. But that, as well as Rouge going out stark naked, only slightly lessened Knux’s embarrassment… 
In addition to the greater feelings of shame, the ball leash sessions were not without the physical pain, which rivaled if not exceeded the ball weights, because these sessions were not so much ‘dog walks’ for Knuckles’ giant fruits as they were ‘dog jogs’, which quickly became ‘dog runs’. As Rouge eloquently put it before the first leash session...
“I should warn you that I like to move fast when ‘hiking’ and I only ever stop to rest and catch my breath. So you best keep pace with me with your legs or I’ll make you catch up with your balls, like so!” Rouge yanked the leash, to which the echidna quickly moved forward with a yelp as his massive jewels were tugged ahead of him. “Which I’m sure is easy for you, since you tagged along with Sonic so much, for so long. Although, I hope that’s not the case, otherwise these sessions will only succeed in humiliating you.” Rouge then let out a laugh. 
Fortunately for her, and unfortunately for Knux, her hope proved true. Though Knuckles was no slouch in the running department and indeed frequently accompanied Sonic the ‘Fastest Thing Alive’ on many an adventure, Knux’s leg power could not compare with his arms and upper body, having always been much more of a puncher than a runner, and he never really kept pace with Sonic so much as he followed the hedgehog’s trail as Sonic blitzed ahead at the speed of sound. Though Rouge also could not hope to match Sonic’s speed, she was still one of the fastest people Knuckles ever knew since; her legs were powerful, she had great agility, her spy training ensured she can move fast in any environments, and could fly, a naturally fast form of travel that she was particularly speedy at.
And so, Knuckles would try in vain to catch up with Rouge on his own during these sessions, but the only thing that allowed him to do so was Rouge pulling him along by the balls with that leash as she ran or flew ahead. The roja male often spent the entirety of these runs screaming, grunting, and groaning as his most valued organs were pulled ahead of him, and the ebony babe would occasionally look back at him with taunting eyes and a smile. The hikes especially got tortuous around the halfway mark as fatigue would set in, making it even harder for Knux to catch up with Rouge, and the resulting sweat made the leather strap on his scrotum quite uncomfortable. 
Making things even more difficult for the strong-fisted echidna was that not all of Angel Island is the lush rainforest that he was most experienced with, and each different environment provided its own little hazards for Knuckles’ balls that Rouge always took advantage of. Ice Cap, being a snow-covered mountain with ice aplenty, was constant torture to the man’s oversized nuggets just from its freezing cold air; Knux’s nuts would try in vain to keep warm via retracting up against the echidna’s body, and Rouge made it even harder for them by tossing snowballs at the male fruit to freeze them into ice balls (all while being undaunted by the sheer cold, despite being fully nude with no body fur). 
Then there was Mushroom Hill, a temperate forest famous for its giant mushrooms that can be bounced on; something Rouge found herself enjoying quite a bit, not only for the airtime they provided compared to a trampoline, but provided an effective and interesting form of ballbusting: since Rouge was always ahead of Knuckles, she would bounce on the mushrooms before Knux could, allowing her to pull his nuts way up high before he could bounce up with her. And upon bouncing, the echidna had to hope he could land properly, lest she make it so he falls butt first on his nuts. And that was only for the occasions when he was able to bounce after her, otherwise Knuckles’ chords got great scrotal stretches from those mushrooms. 
Only one place was worse than the big mushrooms in that regard, and that was Hydrocity: an ancient city that had become a giant ruin submerged in water. Using the Air Necklace (provides a limitless supply of air), the echidna and bat were able to safely swim and dive through the drowned city, and we're especially mandatory for a form of ballbusting Rouge came to favor most of all for the ball leash. Throughout Hydrocity were underwater tubes that strong currents flowed through, and anything caught in them would be helplessly sucked through to the end of the current, with only thin bars allowing the victim(s) to halt their advancement. At least until the person released their grip on the bar, or the current's force broke the bar to pieces. With all that in mind, Rouge would seek out such currents and willingly go into them, Knuckles following in with her or being literally dragged by the balls, and then the bat would grab onto the inevitable bar within the current tunnel, whilst keeping a firm grip on the ball leash but keeping Knux from grabbing hold of the bar… What would then follow was Knuckles screaming out his lungs as he was pulled away from Rouge by the current whilst she hung onto the bar tightly with a power grip on his ball leash, giving his balls the most powerful and intense stretching they could ever receive! It was a sight that Rouge would never miss out on each time they went to Hydrocity, and always got to enjoy every little second of the current’s stretch before either losing her grip, the bar breaking, or intentionally releasing the bar to keep Knux’s sack from breaking off: of which Rouge had an impeccable sense of. 
About the only locations Rouge never dared to hike through with Knuckles was Sandopolis and Lava Reef, as both areas were excessively hot. And anyone who knew how testicles work knew that heat is a serious sperm killer, which would be detrimental to Knuckles and Rouge’s end goal with their arrangement. Besides, both locations were not at all ideal for hiking anyway; Sandopolis being a desert and Lava Reef a lava-filled cavern system.
Luckily for Knuckles, Rouge soon added in ‘rock climbing’ as an activity to do with the ball leash in addition to the running marathons; an activity that the echidna was much more at home with as it works with his greater arm and upper body strength, and the spikes on his namesakes made climbing much less of a challenge for him. Although, Rouge was also a very experience climber and would still get far ahead of Knux thanks to her lower weight, and often using her wings to ‘cheat’, thus allowing her to yank his balls upward. But Knuckles could not mind that as much since at least he could keep up the pace, and the feeling of his nuts being pulled upward gave quite the interesting feeling, even if still painful. 
It helped a great deal that Rouge climbing ahead of the red male gave him the perfect view of her pussy and ass; whether she was climbing or flying above, Knux could see every inch of her dark-skinned, plump crotch and rear, especially as Rouge kept her legs spread nice and wide. Which, as he found out the first time, was intentional on Rouge’s part.
“Enjoying the view? Good! I know that these sessions can be brutal, so I’ll give you plenty of eye-candy to compensate, hun! And this’ll definitely get your seed churning for the big event~!”
And indeed, the sight of Rouge running, climbing, and flying outdoors in the complete nude with her tan skin shining from the sun, was the one thing that made the ball leash sessions worthwhile for Knuckles. Well, that and the genuine exercise he got from the lengthy running and climbing, which made his testes all the more healthy, bigger, and reproductive, and further increasing the echidna’s already greater stamina and endurance: very handy for the eventual sex he would be giving to Rouge.
After the ball stretcher and its leash, the third ballbusting device Rouge introduced to Knuckles was one with the most apt name; the humbler. Essentially two wooden bars with curves that made them resemble a slight ‘W’ and locked onto each other, one above and one below. When connected together, the two bars formed an opening in the middle just big enough to fit the scrotum but be stopped by the testicles. 
Knux knew exactly what he was in for when he first saw the humbler, and scoffed at the device; he already got plenty of stretching from the first two toys, and what could this one do that was any worse? But that attitude changed when Rouge commanded him to get on his knees with his hands to the ground. The red anteater did so, and then his doubts about the humbler were ceased forever. 
Though the humbler was indeed to be worn around the top of the testicles like the previous devices, it was considerably more uncomfortable. The clamping of the humbler would always send a shiver up Knux’s spine, and the feeling of his scrote against wood, though sanded, was not pleasant. And the echidna then learned the hard way the unique nature of the humbler; when applied to a man on all fours with knees down, as he was, the design of the humbler makes it so that should the man attempt to stand back up, or move their thighs in general, they pull their balls in a way most painful. 
And so, for each and every humbler session, Knuckles was made to be remain in a vulnerable and humiliating position for long periods of time. Though this time his balls would not be taut so long he kept motionless, too often the echidna felt the irresistible urge to stretch his, and in turn pull his hangers, forcing him to flex those lower limbs just enough before possibly ripping his sack off. And even then, Knux was not spared of constant testicular torment while in the humbler, for Rouge would still do as she pleased with his huge echidna nuggets. 
Being the fair bat that she was, though, Rouge only ever performed relatively light forms of ballbusting during the humbler sessions; playful slaps and pats, tiny punts from her toes, flicks from her fingers, and so on. But that made little difference for Knuckles since such actions (especially the flicks) still stung like hell. Especially as the type of humbler Rouge used increased the sensitivity of the testicles, so those small attacks felt almost as harmful as a normal punch. 
Although, in addition to those light bustings, Rouge gave those nuts plenty of love during the humbler sessions: luscious licks, sensational sucks, soothing massages, and the like. But the catch was that Rouge would switch between both the gentle and harsh actions at random. One second, Knux would be receiving the best testicle massage from the bat’s silky smooth hands, then the next those same hands would slap his sensitive orbs. 
And that was the real terror of the humbler. As uncomfortable as being physically restrained was, Knuckles already had to force himself into a particular position and not take action unless Rouge said otherwise. But when equipped with the humbler, Knux’s jewels were more exposed and vulnerable than ever, the device isolating them from the rest of himself. Furthermore, the echidna could not even see what was happening to his stones! At least with all other sessions, Knux could see what was to come of his precious testicles. But the humbler sessions filled him with intense anticipation of whether he was going to receive pain or pleasure. 
Truly, the humbler proved itself to Knuckles to be a device to be feared more than the weights and leash, and the echidna would be filled with dread each time it was brought out. And yet, Knux could not help but welcome the use of the humbler at the same time: having developed an appreciation for the humbling aspect of the device after a while, and the pleasure Rouge delivered to his balls during the humbler were some of the best she gave for the whole two months. 
The final device to be used on the echidna, on the other hand, was always the stuff of nightmares for him, and Knux’s legs and hips began shaking involuntarily from the sheer thought of the device: that being the ‘ball crusher’.
The ball crusher had, without doubt, the most complex design of the devices; being two clear acrylic panels connected to each other by a hinge, allowing the two to fold together on each other, with two screws with valve-like heads on the corners of one panel while the other had ‘holes’ that the screws were to connect to, and both panels had bigger holes in their middles. The panel with the screws has the biggest hole, to enable both the penis and the balls through, while the other panel’s hole is sized to only allow the penis through, ensuring the balls remain in between the panels. 
Knuckles would sweat bullets whenever Rouge placed the ball crusher on his genitals, not only from the fear and anticipation of having the torturous device on his most valued parts, but from the discomfort of Rouge trying to fit his rod and fruit through the first hole, no thanks to the massive size of his family jewels. And of course Rouge never went on to modify the holes to be bigger, even as getting the dick and testicles through the holes got more difficult from the spunk tank’s swelling and the dick’s permanent erection.
Once the ball crusher was properly equipped to the echidna’s equipment, then the giftedly endowed bat would immediately connect the screws to their respective holes and begin the crushing process; twisting the valves of the screws to move the acrylic panels together, and thereby squeezing the man’s testicles in between. 
To say that Knuckles was in intense agony from the ball crusher’s squeezing was an understatement. This ‘toy’ was definitely the most painful of all the devices! And possibly even more than Rouge herself. When she kicked, stomped, and punched at his balls, at least they were allowed to be free and swing. But with the ball crusher, there was no escape; they could only remain in between the acrylic panels and be flattened like a pancake. 
And indeed, those orbs would get flat as the panels pushed in on them. And thanks to the transparency of the panels, Knuckles was able to see his round goods get deformed within the ball crusher, which only made the experience all the more horrifying to the echidna. He always tried to look away, but like a train wreck, he could not avert his eyes from the sight. All the while, the incredible fear of Rouge tightening the crusher a bit too much, and the man having to see his eggs get scrambled, flooded his mind. 
Obviously, it never got to that, otherwise Knuckles wouldn’t be recalling the last two months while he waited for Rouge to get her waxing equipment (which was taking a rather long time). But all the same, it was that fear, alongside the intense pain, that easily made the ball crusher the worst experience for Knux. Though the man could mostly trust Rouge not to destroy his balls when doing so with her own body, or the previous devices, Knuckles trusted the ball crusher as well as any other machine with harmful design, such as a blender: that is to say, not at all. And with the pressure that thing would administer to his nuts, it definitely felt like they would burst at any second, even after Rouge stopped turning the screws and simply left the testicles squeezed at a certain point. 
The only thing about the ball crusher sessions that Knuckles could remotely enjoy was when Rouge would jerk him off after getting the crusher to maximum tightness: stroking his cock while his oversized grapes were compressed. It always managed to get the pain and panic out of Knuckles’ mind, replaced with the oddly pleasant feeling of his swimmers churning in confined space. And it certainly was beneficial to both, as those ball crushing handjobs blue’d up those balls real good. 
Indeed, though the bat kept the ballbusting and ball blueing sessions separate, the ball crusher was just one of many occasions in which she mixed the two together, and so Knux’s memories trailed from the busting devices and into the bust-blueing moments. 
The first of such moments that came to the echidnas mind were what he called the ‘porn busting’ sessions, in which Rouge had Knuckles watch porn alongside her. Specifically, impregnation porn. 
It was so evil of her, he always thought; having the echidna watch other men getting to plant their seed, often accompanied with a shot of their sperm penetrating a woman’s egg, whilst denying him the very same thing until his balls were completely blue’d. Even though, as the very last living member of his species, Knuckles needed to breed more than anyone, and do so with haste. 
But there was a very good reason for why Rouge had Knux watch other men impregnate women, one that even he could not help but admit was super effective; watching the porn got him mega horny, and in turn made his seed makers go into overdrive. Knuckles could literally feel his already weighty mansack get heavier with sperm after each of these sessions, which got him more and more pent up and desperate to cum. 
“Ah ha!” Rouge exclaimed during the first ‘porn session’. “So it’s true! You men get really turned on when seeing another man having sex! I guess envy and masculine competitiveness are powerful aphrodisiacs.” 
And indeed, Knux’s four pronged pillar never failed to harden like steel during the first of these sessions. But even after becoming permanently erect, the echidna’s cock was still notably stronger during the porn sessions, complete with a deeper shade of pink. 
For the entire duration of the porn sessions, when she was not content with simply admiring the echidna’s denser nuts and stiffer dick, the nude bat woman would rub the four-headed member with one hand and massage the male melons with the other. Or sucked and licked his rod while sensually stretching his sack. All the while she kept Knuckles’ eyes locked to the porn, watching the man on-screen release his load into the woman, and teased her horny mate with how he cannot yet enter her ‘bat cave’ and fill it with his white flood.
And, as mentioned, poor Knux was not spared from testicular pain during the blue balling sessions, and the porn moments were no exception. When Rouge had Knuckles keep his eye strictly on the impregnation action on the computer or television screen, she meant it, and the echidna allowing his eye to wander provoked her to slap his sack. And should he close those eyes (excepting blinks), even if its from overwhelming pleasure, the bat would full on punch his orbs as punishment. But those were nothing compared to the climaxes; that is, once the man and woman in the porn, Rouge, and Knuckles himself were on the edge of orgasm (which the tanned hottie would ensure was synced up), Rouge would squeeze the echidna’s mangos with all five fingers of her ‘ball hand’. Or all ten fingers, for when she decided to give them nuts the attention of both hands. And with each porn session, Rouge would increase the squeezing power by a notable margin, while Knuckles’ screams of pain get louder and louder. 
The second sort of session for delivering pleasure alongside pain was the differing ‘jobs’ Rouge would employ on Knuckles’ four-headed cock that still allowed for quick and effortless busting of his balls. The first of such that came to the red echidna's memory was the footjobs, which were exactly as the name implied: Rouge using her feet to stimulate Knux’s dick. 
Knuckles remembered how weird it felt to him the first time he received a foot job. He had never seen the ‘sexy’ potential of feet, especially in regards to pleasuring the penis. Hands had sexy potential thanks to their ability to grasp, pull, and so much more. The mouth not only felt the most like a vagina, or anus, but it had the tongue and suctioning. And the boobs? The echidna could hardly believe of think of a hetero man who did not want their rod between a woman’s cleavage. The feet though? To Knux, they were always just an appendage for mobility, and a secondary limb for attacking, and nothing more. That alongside the stench feet are infamous for did not motivate the crimson male to have one touch his four-pronged pillar. 
But that hot bat managed to make footjobs work for Knuckles. Befitting one with such powerful kicks, Rouge’s feet were a feeling to behold. Her soles and heels were rough and hard, yet smooth and pleasant: the contrasts working together for a most sensual rubbing of the prick. And her toes, though fairly odd looking (being slightly elongated and clawed to allow for the upside-down roosting bats are famous for), were able to grasp, rub, and massage Knux’s manhood like no one’s business. The in-between of the toes especially got his meat pumping. And even better, Rouge had to sit down, leaning back, with her legs spreaded nice and wide to deliver the footjobs properly, which allowed the roja man a grand look at her juicy birthing hole. It also helped that Rouge always washed her feets before each footjob session.
But there was a major caveat to the righteous foot jobs; they gave Rouge an insanely clear shot at the echidna’s nuts, as he had to sit with his legs spread for a truly grand footjob. And the temptation to kick those male melons while jerking off Knuckles’ sausage was all too powerful for the tan skinned, white furred bat to resist. 
Whenever Knux got lost in the pleasure trips Rouge’s feet sent him into, he would be awakened back into reality with a swift and brutal kick to the ovals, then the footjob just as quickly resuming. When he would least expect it, Rouge would deliver a crushing blow to those nuts with her heels, with the intent to separate the sperm makers from each other. Pulling one or both testicles towards herself with her clawed toes while using the other to continue the footjob. And in-between each bust, while still giving that four pronged spear love, the fit-built bat would use her toe-claws to give those massive beans sharp pokes. So sharp that Knuckles would have thought he was getting stabbed in the junk if he didn’t know better. 
And come the burgundy anteater’s climax, Rouge sped up her jerking of his phallus with one foot while grasping his balls with the other, then squeezed them with great force with her bat toes. And so, throughout the dry orgasm (its duration extended by the fervent dick rubbing by the bat), Knux had his increasingly purple’d coconuts crushed in a vice grip that just is enough to not mutilate his stones. 
And then there were the boobjobs, which were a dream come true for Knuckles. Ever since he first laid eyes on Rouge’s impeccable pecs, the scarlet echidna wanted to stick his dick in between that great cleavage of hers. Even if he did not know it nor admit it at the time, since he and Rouge started off as rivals at best. But since they had become mates of a most sexual relationship, he could experience those milk factories for the first time.
And they were as glorious as he imagined them to be. Despite how massive Rouge’s cleavage was, it was a super tight for his cock. No doubt due to the heaviness of the bat’s breasts, which were easily a natural F size. How Rouge got such bountiful boobs, and able to do any activity without being impaired by them, was a mystery Knuckles would never solve. But indeed, the weight of Rouge’s mammaries added to the boobjob experience as it made each movement of the bat tiddies incredibly strong, and thus of great appeal to the echidna’s unit. 
But as with the footjobs, there was a catch to the boobjobs: Rouge would perform the boobjobs with both herself and Knuckles in a position that allowed her breasts to land fully on the echidna’s nards. That alone allowed the bat to crush those echidna makers with the sheer weight of her milk makers, but Rouge also always wore a specialized bra that had spikes at the bottom of her tits. Blunt spikes that couldn’t hope to rupture Knux’s testicles, but nonetheless were made of a hard material that added to the pain of those crushing chest melons. 
And so, Knux was always in the most conflicted state during the boobjob sessions as his balls received pain equal to the pleasure given to all four heads of his echidna cock. Each drop Rouge made with her tits sent a wave of ecstasy through Knuckles’ rod, and a surge of agony in his seed bag as those stubby spikes poked harshly into it. Accentuating both feelings were, mid-way through each boobjob session, Rouge would shake her tits rapidly throughout the remainder of the session, as if doing a reverse motorboat on Knux’s unit that in turn made the blunt spikes dig into his testes ever harder. 
Come the climax for the boobjobs, the brown-skinned bat would engulf the four heads of Knuckles’ penis with her chest pillows and really shake them up: stimulating the hell out of the penile glans. Once Rouge felt the echidna’s juice pumping, she would then slam her breasts down at full force for one last rub of the shaft, and most importantly to deliver one last instance of torment to those echidna gems. 
That breast slam to the jewels never failed to make Knuckles fill the room with his anguished scream, as the spikes of the bra, aided by the crushing weight of Rouge’s own jewels, practically pierced his red and purple nuggets. If not for the spikes being blunted, Knux knew his boys would have burst outright. And all the while, the echidna’s exotic equipment quaked with the urge to cum all over Rouge’s chest but unable to expel even precum, which made his pearls doubly ache as the blueing took hold on them. Truly, those bat tits were too good to be completely pleasurable. Still, after the pain would dull, Knux could not help but find the agony worth the experience of being in Rouge’s cleavage. 
But Knuckles reserved the most intense memory for last, and that was the pussy hotdogging sessions. Rouge had made it clear when she first set her eyes on the echidna’s quad beauty that she wanted it deep in her pussy. But she would not be able to that for the two months since being inside a pussy was the only way for Knux to cum, and doing so would not only ruin her plan for his balls to get blue’d but get her pregnant too soon. 
But after a week or two, Rouge came up with a loophole that allowed her to at least pleasure her clit and nether lips with Knuckles’ cock without him releasing his balls’ contents; she could not have him penetrate inside her pussy, but she could certainly grind her pussy against the base of his dick, as if she were scissoring. Or, as the name suggested, putting his hotdog in her buns. Thus both she and he would get proper nether stimulation, but Knux would still be prevented from cumming by his own biology. 
As luck would have it, this idea of hers worked, and ever since Rouge got to kill two birds with one stone in pleasuring her beloved puss whilst keeping Knuckles’ balls pent up. And as a huge bonus, this session got them fruits blue’d to an exceptional degree, since the contact between the penis and pussy got Knux mega horny. 
Which was why this session ended up being the most intense for the cherry-colored male: whenever Rouge’s baby maker got up against his four-pronged member, his desperate desire and need to breed kicked into overdrive, and made the inevitable denial all the more bitter and agonizing. How could she allow their crotches to meet and not allow the man to do what he needed to do most, and was the purpose for their arrangement in the first place; to repopulate the echidna species? 
And the resulting dry orgasm were the strongest of them all, without question. If the male echidna’s reproductive system did not function the way they did, Knuckles would have been erupting cum like a geyser. But alas, all his four-holed pride could do was futilely pulse with all its might while his balls pumped in vain 
But in addition to that sexual denial of the utmost sadistic, Rouge was also able to deliver a real good squish to Knux’s orbs. Thanks to the way the two positioned themselves for the pussy hotdogging, the bat’s plump butt cheeks was always right above the echidna’s eggs. And with Knuckles' legs spread wide open, Rouge was able to hit those virile spheres with heavy hip drops at a rapid rate. 
It was a tragic twist for the scarlet bruiser, for he had been looking forward for the moment his balls would first make contact with the bat’s ass. But instead of his round goods slapping against Rouge’s bum during the breeding sex, her behind was slamming onto his valuables as they lied helplessly on the ground, all the while the bat teased his cock with the touch of her pussy lips. 
And yet, as agonizing as the ‘buttbusting’ was, Knuckles came to enjoy it quickly than he did the other busting methods. As damaging as Rouge’s ass felt on his balls, there was no other feeling like it. To have his testicles squeezed to the cold, hard surface by his mate’s warm, soft yet firm butt felt intensely good, once he could set aside the pain factor. And the buttbusting cemented all the more to Knuckles the power and thickness of Rouge’s tan bottom; truly, this bat was the perfect woman to breed with, for she would be able to carry ten or more echidna kids at once and have an easy time doing it. 
Come the climax, Rouge would lift herself so her pussy lips were just barely touching the heads of Knuckles’ members and shake her waist side to side for a vibrating-esque effect. That level of pleasure to his netherheads, combined with the mesmerizing sight of Rouge effectively belly dancing in front of his eyes, got Knuckles’ sperm churning like no tomorrow. Upon announcing his oncoming orgasm, Rouge would then lift herself up higher with her wings, channel all her weight into her entire rear end, and then slam down swiftly and brutally onto his echidnads. 
Knuckles would shout a mighty shout as his beloved treasure were pressed underneath that bat’s derriere, experiencing the weight of Rouge that’s held back up enough to not reduce his sperm makers to paste. The echidna’s entire four-headed glory would spasm with great vigor, thinking that it had finally hit home run from contact with Rouge’s pussy, only to realize that was not the case and turn completely red from that failure. All the while, Rouge revelled in the feeling of Knux’s nards beneath her bottom cheeks and the incredible sexual frustration that then surged all over the echidna, most prominently in his penis and suffering balls. 
--------------------------------------------------------------------------------------------------------------------------------
Having finished recalling all the memories that stuck out in his mind, Knuckles snapped back to the present time; sitting on his bed, waiting for Rouge to return to wax one side of his balls. 
“Okay, got my supplies!” Rouge announced, as if on cue, and walked back into the bedroom with her waxing kit; an electronic device resembling a pot of sorts filled with melted wax, and wooden waxing spatulas. “Sorry for the wait. Had to balance the heat of the wax so it would melt, but not be hot enough to kill your swimmers.” 
Knuckles coughed to clear his throat and looked at Rouge with a grin. “Heh, no problem! Thanks for taking the condition of my seed into consideration.” 
Rouge winked. “Of course! It’d be very rude of me to decrease your baby batter right when we’re about to start baby making. Especially after all those bustings you allowed me to do.” The nude, dark-skinned bat dipped one of the waxing spatulas in the pot of melted wax and stirred it. Then she scooped up a glob of the sticky substance. “Now, you ready for your first scrotum waxing?” 
Knux looked at the melted material with an unsure look, but quickly adopted a confident expression. “Ready as all the other first times!” The echidna then spread his legs wide to present his goods to Rouge. 
“Hmhm! So eager to get busted now, are we? I knew you’d start to enjoy our ‘moments’ together soon enough.” 
“Well, the bustings have grown on me a bit. But I’m mostly eager just so we can get on with the breeding after this.” 
“Hm, if you say so…” 
Not wasting any time, Rouge slathered the melted wax onto the front of Knuckles’ right testicle, having chosen that nut due to it being the bigger of the two, which made the gland rise up and cause the echidna to shiver from the feeling. As Rouge had said, the wax was warm, but not at all to a degree that would harm the nutbag, much less the sperm. If anything, the wax felt nothing short of pleasant to the massive seed maker and its protective sack. 
The gelatinous substance soon cooled itself into a solid (which mildly tickled throughout) with Knux’s fur intertwined within, and right when the wax got hardened enough, Rouge pinched the top part of the wax with her right, and gripped the oversized grape to keep it in place for when she pulls off the wax. At that moment, Knuckles formed a panicked expression as realized something he should have asked. 
“Wait…! You completely know what you’re doing, right?” 
Rouge looked up into the echidna’s eyes with a warm smile. “Of course! I’ve been waxing since I hit puberty.” The bat then glanced down at her torso. “And let’s just say I wasn’t born with my body being almost entirely exposed, smooth skin.” Knux glanced all around Rouge’s body, his face turned to one of interest, while Rouge focused her eyes on the wax on his right ball. “Now, don’t hesitate to scream anything you want. This will sting.” 
With that, Rouge tightened her grip on the hardened wax and Knux’s scrote, then ripped the wax off with swift force. 
“HOLY MOTHER OF GAIA!!!” Knuckles screamed at the top of his lungs, bending his torso back as tears leaked from his eyes from all the fur on the front of his scrote being pulled off at once: the pain magnified by the scrotum’s increased sensitivity from the past two months. 
“Oh~, nice shout! Now start thinking of two more interesting ones, cause I have to move onto the side and the back…” 
The bat scooped up the wax from within the electric pot and covered the side of Knux’s right stone, waited for it to harden, and then pulled it off like a pro. That time, Knuckles’ right leg and foot twitched with small and quick taps to the ground and he arched forward. 
“OOOHH MY ANCESTORS!!!”
“Knuckie, it’s your children in there, not your ancestors!” Rouge looked away as she held in a laugh “Heehee, now I’m wondering how his ancestors think of him willingly allowing his only means of having children be abused like I have.” The bat then looked back to Knux with a smirk. “Okay, now I’m going to need you to lie on the bed on your belly with your legs spread so I can get the backsack.
Knuckles groaned as he turned around on the bed and lied flat on his front with his legs wide apart, allowing Rouge access to the back of his balls as the whole sack rested on the bed. Once more, melted wax was slathered all over the back and the underside, of the scrotum, and then stripped away upon solidifying, pulling off all the red fur from the backsack. And once more, the brawny echidna howled up at the sky in agony; his eyes shot open with tears pouring out. 
“FUUUUUCK YOU, BITCH BAT!!!” 
“That’s ‘Bat Bitch’ to you, Knucklehead!” Rouge snickered as Knuckles panted from the residual sting of the ball waxing, then tossed away the used strips of wax and placed her waxing kit on a vacant table. 
“Sorry… I didn’t mean to call you that.” The scarlet warrior pushed himself up and sat back onto the edge of the bed, his right testicle pulsing as it hung alongside its unwaxed brother. “That last one really hurt.” 
Rouge placed a hand to one of Knux’s shoulder. “You’re good, hun. I knew that was the pain talking, not you. At least it’s all over.” The seductive bat crouched down to get a close look at the echidna’s freshly waxed right melon, which had become exposed skin with a deep blue hue. “And now I’ve got the best of both worlds; a smooth sapphire to complement my rugged amethyst.” Rouge cradled and massaged the male gems, then rubbed them against her cheeks. The bat savored the feeling of the right’s skin and the left’s fur against her face whilst Knuckles winced from the pressure to his tortured boys, but enjoyed the ‘worship’ nonetheless. 
After getting her fill of the blue and purple testicles, Rouge stood back up with her hands to her hips. “Alright, my pent up stud! Let’s get started~!” 
Rouge flew up into the air of the bedroom, hovered over Knuckles, and then landed onto the bed on her back. “I’m all yours now.” She then gripped the underside of her thighs and opened her legs as wide as she could, to which her vulva opened along with it. “Come on over and fill me with your babies!” 
Knuckles’ eyes shined as they opened in full from the sight of Rouge’s exposed pussy hole, which he could hear begging to be penetrated by his four-pronged spear, and said spear had reddened and hardened ever more at being invited into the bat’s cave. Within an instant, Knux crawled over to Rouge and got on top of her; he could hardly contain his excitement as he cheered toward the sky.
“YYEEEEESSSSS~! FINALLY!!” The echidna then locked eyes with Rouge, with a grin of immense satisfaction. “Prepare to get knocked up by the very balls you’ve been abusing, you sexy batshit sadist!” 
Rouge’s cheeks turned red as she smiled back at Knux. “Mm~! I love it when you talk to me like that, you hunky beast!” She then directed her sights to her crotch, where Knuckles had his love rocket aimed directly at her opening. 
The four penis heads pulsed with intensity as they readied to dive into the bat’s womanhood, and his penile holes expanded for the inevitable flood of cum will expel (of which Rouge noticed, and got wet from the prospect of). 
Knuckles was all set to thrust his cock into the bathole, but resisted that urge and decided to do nothing for the moment. After two months of being absolutely submissive to Rouge, he gets to be dominant over her, positioned on top of her with his glorious member about to ravage her puss. He also got to do what Rouge did to him all that time and deny her what she wanted most: his exotic equipment in her snatch. And indeed, she had a look of great anticipation and desperation in that moment as she waited for Knux to plunge into her nethers. 
Once he felt enough time had passed, Knuckles reared his hips back, straightened his cock, and then moved in for the long overdue penetration. But just before his very tips could touch Rouge’s lips, the echidna had a last second recollection, to which he sighed in self-disappointment and pulled away from Rouge, much to his sexual frustration. 
“Hey! What are you doing now?!” Rouge shouted as she sat up with her arms crossed. 
“Grr, I just remembered we were supposed to go to Tikal before we start to breed, so she could do that thing that would make us only bare pure echidnas.” 
Rouge dropped her arms and her expression changed to one of realization. “Oh right! I guess we both forgot after two months.” She giggled with bashfulness. 
Knuckles sighed again, and turned away from Rouge and to the bedroom door. “Come on, let’s go see her, before my balls ache too much…” 
Rouge breathed a deflated sigh, having wanted to get that D inside her ever since she first laid eyes on it two months ago. But then she grinned with amusement at the table being turned on her, as well as Knuckles’ comment. The winged beauty flew off the bed and out the door to go to Tikal with her red-clad mate.
