Father Know's Best

At the crack of dawn, Josh quietly entered his fathers bedroom.  His father was snoring peacefully as the first rays of the morning sun crept into the room. His muscular frame barely fit on the queen size mattress, and Josh knew that his father was entirely nude under the thin sheets.  He had requested that his father maintain nudity at all times while in the household and to always keep his legs open for free use. The older man's trained legs were spread wide and his bulging thighs directed the eyes casually towards a massive tent in the sheets indicating his father was enjoying a pleasant dream.

Gently, Josh lifted the covers at the base of the bed and snaked his hands up towards his father's morning wood, caressing his dad's muscular thighs which were covered in a thick layer hair before reaching his target, his fathers massive orbs.  He carefully encircled each massive orb with both hands, rolling the dense organs around slowly.  A faint smile appeared on his slumbering father's face as his son gently caressed his testes, rubbing each part of his babymakers gently and pleasurably.

His father sported the largest pair of nuts Josh had ever seen, despite his years in the locker room showers from a lifetime of athletics.  They were the size of small oranges, and incredibly dense, able to take an incredible amount of pressure before distorting, an act he had tested innumerable times. Above his gargantuan testes was an massive uncut cock, easily 9 inches long with incredible veins down it's length. It was a behemoth of a cock that men could only dream of obtaining. When brought to orgasm, the horse cock released ridiculously thick loads of cum nearly unendingly due to the large reservoir of semen housed in his continuously blue balls. While Josh never stimulated his father's shaft, it leaked precum constantly during their frequent "virility" lowering sessions.

A damp spot was rapidly forming at the precipice of the tent in the sheets as the first of his fathers virile juices began flowing.  Josh smiled at his blissfully unaware victim, before digging his thumb deep into the membrane of each nut.  His thumbs slid deeply into the nut flesh that once birthed him, causing his dad’s nuts to distort horribly and take on a reddish hue from the sudden pressure.

"Good morning Dad!" Josh spoke cheerfully, rotating his thumb so his nail sunk deep into each meaty orb.  His carefully trimmed nail dimpled each large organ brutally, his inquisitive fingers pressed into his balls inward towards each other as if Josh was attempting to make his fingers touch through the meaty organs.

A slight groan indicated that his father was abruptly awake, and he briefly attempted to close his legs before engaging his core to allow his son access to his babymakers.  He was well trained from years of practice to keep his legs open, and nuts available, whenever his son felt the need to bust him. Even in his sleepy state, he knew to make his equipment available for his son’s pleasure.

"G-good morning son." Mark groggily replied. "You're up early today."

Mark glanced down at his own rock hard cock, which was slowly drooping from the intense testicle pain his son was inflecting.  It felt like a knife was stabbing his balls each time his son pressed his nail into them.  Josh’s trained hands sunk deep into their girth, causing them to comically distort. Conversely to the pain, his half flaccid cock twitched pearls of precum with each nut cracking probe which were splattering his chiseled abs.   With enough "stimulation" Mark's muscular torso would look like a grisly "Jackson Pollack" painting.

"It's the first day of Spring Break, so I wanted to get a head start on the day!" Josh said brightly, while pulsing his thumbs absentmindedly into his father's testes and watching his fathers cock twitch with each probing squeeze.  It was a tantalizing sight, despite Josh's affirmed heterosexuality.  He knew there was at least a weeks worth of cum inside his father's orbs, aching to get out and he enjoyed watching the beleaguered manhood struggle to relieve itself without stimulation. Josh refused to allow his father to relieve the pressure himself or to assist in the process himself, enjoying his father's sexual frustration and only allowing nut pain related orgasms.

“Aii-Mmmmmph!”

Mark silenced a scream as his body reacted unconsciously to the mashing his spuds were taking.  He knew better than to cry out with what Josh would consider “light” ball play, lest he segue into heavier play without giving him time to acclimate to the sweet agony. 

“Oooo they’re extra sensitive today, huh?” Josh grinned sadistically. He had spent the previous evening drinking heavily and busting his dad’s bull nuts with reckless abandon late into the night. There was still some light swelling from that previous session further bolstering their impressive size.

Josh knew every part of his dad's testes intimately from years of daily torture. He was careful to crush each section of the heavy balls evenly, without giving his dad's balls a chance to rest. He twisted them and pulled them brutally while dimpling the orbs cruelly with his strong fingers.  Yanked to their limits in their sack, his father's nuts had no where to escape to.  The meticulously shaven testes were mashed and mauled in near silence, with only a few morning chirps of birds interrupting the silence.

"So I was thinking Dad..." Josh said carefully, switching to crushing just his fathers left orb with both hands.  The nut distorted to half it's usual girth and Josh continued to pulse his fingers further into it's depths as if determined to reach the center of the meaty organ.  "I'm going to be graduating from college soon and will have to move away soon after for my internship.  What are we going to do about our little problem here?”

He nodded his head down at the beleaguered organ, as if to highlight the issue at hand.

Mark moaned as he felt his son's fingers sink deep into his left nut, almost to the knuckle.  His ball was beginning to swell horribly from the treatment and he was panting slightly in concentration to not pull his body away from the brutal ball play.  He knew all to well the punishment for disallowing his son full access to his reproductive organs.  His cock, however began to inflate as the gears began turning in his head.

"W-what do you have in mind?" Mark managed to spit out, before a particularly rough squeeze silenced him.

"Well, it's just a thought, but..." Josh spoke wistfully, "Well, we’ve put a lot of mileage into these babies here and you know what I’ve always wanted to do before leaving the state...”

Josh let his fathers nut free from his crushing grip. It fell against his dad's thigh with a meaty slap before plumping up to it's normal size again.  It came to rest languidly on his muscular leg, like a bruised kumquat.

"You mean, like..."

THUD

Josh's fist came crashing down onto his dad's balls, pounding them against his pelvis. The left, more swollen nut was especially assaulted, flattening to a fraction of it's normal girth between his pelvic bone and Josh's knuckles.  Due to their natural size it was difficult to strike both with a single blow, but Josh was a semi professional fighter and talented ballbuster.

"Rupture of course!" Josh gleefully spoke, his voice piercing the quiet morning air as his father squealed from the nut pain, and thrashed his legs about, knocking the bedding to the floor.

A wave of pain overwhelmed Mark's brain, but his cock responded to his son's question before he could, inflating to full mast in a fraction of a second.  His impressive member slapped rigid against his abs as he fought to maintain control over his body. A single pearl of precum formed on his engorged cock, glistening in the sunlight, before splattering against his abs as he involuntarily twitched on the mattress.

Josh stepped back from the bed and smiled at the cruel scene.

His own cock had inflated to full mast from the sound of his father's keening screams, and he slipped off his basketball shorts casually to allow his cock to hang freely in the morning air.  Josh had inherited his father's virile masculinity, sporting a thick 8 inch uncut cock which hung rigid in the cool morning air.  He began to absentmindedly jerk off at the sadistic erotism of ruining to nuts that birthed him.

Below his thick shaft was a pair of testes that most men would only dream of owning.  While not as large as his fathers, they were thick, kiwi sized balls that Josh had worked extensively on stretching lower with weights over the years.  They hung nearly 5 inches from his taint, and jiggled languidly with each stroke of his shaft. His father identified as a straight male, but Josh would often force him to gently suckle his lowhangers gently during their sessions.  The disgusted face his father would make each time only served to turn him on more.

“Mmm now that was a solid punch!” Josh said, flexing a bicep arrogantly. 

Josh was a gorgeous male specimen, with a rippling musculature from years of MMA fighting and weight training. At 6’2” he surpassed his father in height, but his father had him beat in pure muscle mass. He sported well developed pectorals and perfectly contoured abs that led the eyes naturally to his impressive manhood.  Coupled with his trained body, his sadistic mind made him the perfect ball buster.

Mark's left testicle was swelling at a rapid rate, now obviously larger then it's counterpart and turning bright red from the brutal treatment. Conversely to the agony radiating from his loins, his cock was harder than ever.  It was so engorged with blood it was almost painful and a steady stream of precum was now streaming from his cock and dribbling onto his abs.  Mark engaged his core and forced his legs apart for his son, knowing that he was hardly done with his babymakers.

"You really wanna try and crack them?" he asked, arousal heavy in his pained voice.  Castration fantasy was often a theme of their sessions, but despite the years of reckless testicle mashing, his nuts had never succumbed to bursting.  They were incredibly tough organs and were trained to take incredible amounts of punishment that would neuter most men.  There was seldom a night that his testes weren't swollen and bruised, but his huevos always plumped back into shape and had never taken permanent damage besides short term sterility.

Josh dropped his cock, stepped forward, and reached between his father's legs, caressing and squeezing the reddening testicles.  He gently rotated his thumbs into the meaty organs, smiling as his dad arched his back pleasurable and moaned from the sensation. Then, he increased the pressure. He sadistically dug his nails into every part of the fragile orbs, dimpling them cruelly and feeling for weakness in the dense nuggets.  They had taken a ridiculous amount of abuse over the years that Josh was cohabiting, and it would be quite the challenge.

"It'll be the perfect solution for your problem here Dad." Josh smiled devilishly and Mark's cock twitched again in fear. "It's gonna be tough! We'll have to work really hard to crack em'... But I'm willing to do whatever it takes."

His playful tone shifted to something more sinister. There was nary a night that Josh didn’t fantasize about ruining his stud of a Dad. He had been given full permission to remove his father from the gene pool years ago, but was now ready to complete the deed. 

He looked down at his fathers distorted orbs almost wistfully. While the act of ruining them made his cock twitch in desire, he also knew he’d miss the thick eggs once they were gone. Some of Josh's greatest orgasms had come from mangling his Dad's manhood, and he was slightly hesitant to finish the job.

Their relationship had initially been one of normal familial values, until one evening when Josh came home from practice to find his father hunched over a stack of bills with a scowl on his face.

"What's up Dad?" He asked.

His father leaned back, sighed dramatically, and spoke.

"Just going over finances for the month.  Business is in decline and nearly half of my income is going towards damned child support this month."

His voice sounded tired and bordering on annoyance.

Josh was one of five children, from four separate women.  Mark was incredibly virile, and even with protection and birth control, he found himself paying for either plan B, abortion procedures, or ongoing child support regularly.  Almost every date that ended in coitus over the past months had resulted in a difficult phone call days later. Mark, being an incredibly sexually charged male was hesitant to taper his sex life despite the ongoing cost and risks.

Josh stripped off his gym tee before taking a seat across from his beefy father, his abs drenched in sweat from an intense workout at his boxing gym.  There was a noticeable bulge in his basketball shorts where a jockstrap attempted in vain to secure his member. The lump in his shorts inevitably jiggled with every movement and Mark consciously avoided eye contact with it.  The two of them were very comfortable with their masculinity and were both often in a state of undress even before their relationship took a sadistic turn.

"Damn that sucks Dad, have you tried pulling out?" Josh smiled wryly, wiping his brow with a hand towel. They had a playful relationship, always quick to proverbially bust each other’s balls.

Mark glanced up at his son, unamused, before resuming his work.

"Your old man here is too much of a stud apparently, and that comes with a cost sadly," he retorted dryly, flexing his bicep arrogantly.

Josh laughed, but also eyed his fathers muscular arms with envy. His father was even more popular with the ladies then he was. The older stud was able to score dates with the hottest instagram models and models in the city with seemingly little effort.

"You know..." Josh said, cautiously, "One of my workout buddies, Matt, was telling me there is a one-hundred percent effective male birth control method that him and his girlfriend have been trying.”

His father shifted the bills in his hands, focused on the numbers in front of him and noncommittally grunted. 

"Apparently, the day before they have unprotected sex he always 'forgets' his cup at home.  A kick or two and he's shooting blanks."

Mark looked up and raised an eyebrow incredulously.

"What? You're telling me you kick your friend in the nuts before he goes on dates?"

"Only if he doesn't get nailed during practice! Sometimes we meet up after practice and take turns kicking his nuts. It's sort of a post-workout ritual for the guys... Wanna see?”

Josh pulled out his iPhone and scrolled through his photos, pulled up a video and rotated the screen towards his doubtful father. 

The short fifteen second clip was shot POV by Josh, and the camera was focused on his handsome friend Matt. The boxer briefs the athletic stud was wearing did little to obscure his lofty manhood and the jock was goading Josh and his other friends off camera. 

“Come on, pussy, lets go!” The inebriated jock slurred, spreading his legs wide and inviting punishment. The outline of his half erect cock was plainly visible so Josh knew just where to aim to hit the vulnerable bits. 

With a loud thunk Josh’s foot crashed into Matt’s crotch. The video was edited in slow motion to highlight the ripples of force as Josh’s toes smashed the jocks balls with surgical precision into his pelvis. Matt’s eyes bulged, his face scrunched up as the waves of agony took over, before crumpling into a heap. 

“Ooooooooooo!”

Matt squealed girlishly and thrashed about on the ground, clutching his nuts. 

"Fuck yeah!" Josh yelled, "I win this round."

The disappointed groans of Josh's gym mates indicated this was not the first kick Matt had taken his evening.  This clip ended with Josh zooming in on his friend's anguished face before panning down to his crotch.  A noticeable tent in his friend's shorts suggested that the strike had been more enjoyable then it looked despite the pained expression on his face. 

“It’s something we do on a weekly basis now,” Josh stated, sliding his phone back into his shorts. “So far, he’s childfree, and without any long term damage to his goods.”

Mark was stone faced to his son's gleeful sadism, but inside his mind gears were turning as the hours of finances left him bleak and tired.   He had tried all form of male contraception, but despite spermicide, condoms, and never allowing himself to finish inside a women his income was still diminishing after each sexual encounter.

"So you're telling me, if you use my nuts as a punching bag, I won't impregnate anyone?" Mark frowned.  

It didn't make any sense to him, but he had very little knowledge of biology compared to his STEM major son, so there was a very good possibility that Josh knew what he was talking about. There was also a good chance he was merely messing with him to get some pot shots at his nuts.

Mark was painfully aware of his son’s proclivity for busting nuts. 

From a young age Josh had shown an interest at sack tapping his balls. Mark couldn’t even count the number of times his son had smacked his nuts in his youth, often laughing at his pained reaction and sprinting off in youthful glee. Mark himself had grown up sack tapping his own friends and never discouraged his son from the "game" he obviously found hilarious. Plus, he enjoyed showing off his high pain tolerance and bulge as an alpha male. To imagine putting himself into that position of submission intentionally, was difficult for him to imagine.

"Well... I can't say for sure..." Josh replied slowly, shifting his body to obscure the erection growing in his shorts. The thought of getting a new target, and a target as large as his father’s, was riling him up. "But I'd personally say its worth trying, if you're man enough to put your balls on the line."

Mark snorted, pushed away from the table and stood up.  The sweatpants he was wearing did little to disguise his impressive manhood, with two large lumps plainly visible where his massive nuts were trapped against the fabric.  Making eye contact with his son, in an act of machismo, he lifted his hand dramatically, curled his fingers in a fist, and drove it rapidly into his bulge.

SMACK

Josh watched, mouth agape, as ripples of force caused his bulging orbs to to jiggle tantalizingly.  The strike compressed his right orb brutally, knuckles denting the thick organ. The force blasted them up into his body, warping the nuggets against his pelvis.  Mark did not utter a single sound despite the brutality and instead smiled at his son's reaction, removing his fist and gripping his crotch arrogantly. 

Mark laughed, jiggling his bulge around and wincing slightly at the sensation.

"I think I can take whatever you can dish out, kid.  Go grab a six pack from the fridge and let’s head back to the garage.”

That evening was one of numerous beers and pot shots against his dad’s bulge. His dad discreetly ignored his son’s obvious erection in his shorts and continued to pound Corona until the ache in his nuts was more of an afterthought. It was an incredible bonding experience for both of them, and the night was full of laughter and sound of Josh’s foot rocketing up between his fathers legs repeatedly.  

The following night, after a sweaty night of passion with a Latina instagram influencer, Mark experienced the effects of the heavy ballbusting, for the first time in ages he received no frantic DM or call about emergency contraception. 

That day forward, Josh became his father's personal fertility manager.

Their relationship became one of increasing sadism and masochism, with his father's nuts smashed and mauled until swelling before every potential sexual encounter.  Mark found it sometimes difficult to sit normally at dinner with his date due to his broken nuts, but it was well worth it to bury his load deep into his partner without concern. His son's well trained fists (and kicks) were an efficient spermicide, decimating his virility temporarily, and Mark soon discovered he enjoyed the feeling of cumming with bruised nuts.  Inside his brain, the wires designating pleasure and pain became intwined, and he found himself encouraging his son towards harder and harder testicle torture play.

At some point, however, the "friendly" sperm killing sessions turned into something darker. 

Torturing his fathers nuts turned from a dating failsafe to a nearly nightly endeavor as both parties became attuned to the sexually charged nature of ballbusting. Soon there was nary a night that Mark didn’t fall into his mattress, sweaty and moaning in agony with freshly juiced lemons swelling in his sack.

For Josh, there was something about punting his father in the nuts that felt intrinsically correct to him. Perhaps it was natural instinct to remove a superior male from the gene pool or perhaps it was simply how his brain was wired. Damaging testicles was better then sex for him and after a few sessions with his dad he forwent any bashfulness and openly began jerking off during their sessions. Mark himself began stripping down before their sessions, allowing his son to kick and punch his naked nuts until they both came explosively. He spent many nights using both hands to bring his cock to the brink of orgasm while his son crushed his nuts against the garage floor. 

Josh came to crave ballbusting, and Mark slowly gave more and more control of his manhood to his son’s budding sadism. His nuts became the playthings of his progeny, and he kept them readily available for whenever his son might need them to destress.

Eventually, the months of consistent nut pain broke the alpha male entirely.

His masculinity was shattered, psyche broken and reformed with only one thought. To provide for his son as a piece of meat to torture, until his balls were irreversibly broken by his son’s hand. It was a complete shift of personality from the affirmed alpha male, whose muscles and cock alone put him into the top percentile of men. 

Mark then chose to remove himself from the dating pool entirely, giving full control of his testicles to his increasingly sadistic progeny. 

He was ordered under threat of castration to forgo masturbation and sex entirely and was only allowed to orgasm through ball pain. The virile muscle stud was reduced to begging for nut pain constantly with the hope that a well aimed knuckle punch could relieve the built up sperm inside his titanic balls. Hundreds of loads were knocked loose from his beleaguered balls, but now their play sessions were entering the final stage.

"Alright, here we go!"

THUD, THUD, THUD, THUD, THUD

Mark was roused from his nostalgic thoughts by Josh’s muscled leg, racketing up between his legs. 

With a loud, visceral sound, Josh's well trained shin pounded his fathers nuts against his pelvis with surgical precision.  Each blow was harder than the previous one, distorting the organs harshly with each resulting blow.  The huge orbs were flattening brutally, squished to half their normal girth with each strike.

"MMMMMmmph!"

Mark screamed into his gag, spittle flying as he thrashed about.  Even if he wanted to ask for mercy, his son had forbidden the use of a safeword. His legs quivered with each relentless blow. 

THUD, THUD, THUD, THUD, THUD, THUD

Mark was standing in their living room, his hands on top of his head like a hostage in his own house, and attempting to keep his legs spread wide while his son kicked his manhood from behind. Sweat was trickling down his chiseled body and his veins were bulging all over his muscular body from the effort to remain planted in place.  He had received strict instructions to leave his legs open for as long as his sadistic son desired, and from the intensity of the blows it appeared that Josh was determined to end his manhood right now, or at least he no longer was concerned with “explosive” repercussions relating to high levels of blunt force. 

THUD, THUD, THUD, THUD, THUD, THUD

“Eiiiiiiiiiiiieeeee”

Mark’s screams took on a high pitched keening tone through the gag as huge nuts were pancaked into his pelvis, he was sure his sack was soon to be a lumpy mess of reproductive pulp. His nuts bulging and distorting with each blow harder than the next. 

THUD, THUD, THUD, THUD, THUD, THUD

The thought of his balls imploding under the blows caused Mark’s blood pressure to spike and his thick cock was drooling precum with each testes warping blow.  His massive erection, which never faltered despite the blows, was taped against his abs such that his member would not in the way of the onslaught. The impressive shaft pulsed with each testicle cracking kick on the brink of orgasm despite the danger his testes were in.

THUD, smack, THUD, smack, THUD, smack, THUD

Josh began adding targeted toe strikes each each of his father's orbs in between each shin strike which effectively smashed both equally.

"Fuck yes," Josh grunted, eyes focused on the increasingly swelling sack.

Josh was entirely naked and sweating profusely from the intense cardio of repeated kicks.  With each strike, his own cock, which maintained nearly diamond like hardness throughout the torture session, flopped up against his abs with a dull thud. His trained body glistened in the early morning sunlight and his handsome face was scrunched tight in concentration.  Pearls of precum were flying from his cockhead, as the feeling of his fathers nuts pulping between his toes was nearly bringing him to a handsfree orgasm. The tarp that Josh had laid out beneath them was peppered with precum that was flowing freely from both men.

THUD, smack, THUD, smack, THUD, smack, THUD

Mark's nuts were a mess, swollen and distended from continuous strikes. His bombarded sac was bright red from the abuse and each strike seemed to sink deeper into his precious sex organs.

THUD, THUD, THUD, THUD, THUD, THUD, THUD, THUD, THUD

Deeper, and deeper, and deeper, and deeper. 

THUD, THUD, THUD, THUD, THUD, THUD

Mark’s voice died within this throat as the intensity increased again, physically lifting his body from the floor with each strike. His orbs were distorting horribly from the pressure, forced into impossible concave shapes by Josh’s toes. Waves of agony surged through his body with each testicle ruining strike.

THUD, THUD, THUD, THUD, THUD, THUD, THUD

His left nut, which had a slight relief during breakfast, was taking further abuse beyond it's limits and turning bluish from the harsh strikes.  Josh was expertly singling his Dad's individual nuts out, forcing his toes deep into the doomed organs with incredible velocity. Josh was faintly aware that the nut was getting mushier and mushier with each resulting blow.  If he kept up this intensity his dad’s nuts were sure to...

BEEP BEEP BEEP BEEP

"Dammit! That’s time!" Josh exclaimed in frustration, relaxing his stance and turning his attention to the timer on his phone. 

With a thud his father fell to his knees, tears welling up in his eyes blurring his vision, drool trickling down his face. The agony of the nut pain was beginning to set into his body, causing him to quiver and blubber into his gag pathetically as his body attempted to acclimate to the sensation. 

Josh smiled and walked up to his father, gripping his manhood casually. He was a few strokes from firing a load all over this father's anguished face, but he wanted to savor the moment.

“I was this close to popping them Dad!” He smiled brightly, surveying his fathers spasming body. “Maybe we should have tried for ten minutes instead?”

With his free hand he unhooked the ball gag from behind his fathers head. It slipped from his agape mouth with a wet plop and splattered on the floor. His mouth fell slack jawed despite the removal of the gag, globs of spittle coating his lips.

“My balls... my balls...”

Mark was unable to utter anything else. He repeated the mantra over and over staring vacantly down at his huevos, which were distended in their sack and swollen so brutally they were touching the floor.

The waves of agony coursing through his body were unlike anything he had experienced in his years of genitorture. His cock had wilted against his abdomen and slipped out from its constraint as the copious precum weakened the adhesive. 

His balls were beginning to swell horribly, no longer taking their normal oval shape. They were lumpy, and rapidly turning black from the internal damage. His left nut was especially ruined, distorted into an orange sized mass of flesh. Mark was scared to even touch it, might it burst apart in his sack.   

The sight of his dad’s nearly destroyed testes was too much for Josh to handle. Overcome with lust, he dropped his pulsing cock and stepped forward such that his dripping erection was pointed directly at his father’s open mouth. Mark’s eyes flicked upward at his son, pleadingly, but knowing what was to come. 

“Suck it, or I ruin you right now,” Josh commanded, his voice cold as ice. He hovered his foot over his fathers manhood, threatening to stomp the life out of his damaged balls.  Mark knew a fell aimed stomp with his nuts against the hard flooring would mean game over for his nuts.

Mark’s face frowned in humiliation. As a lifelong affirmed heterosexual man, he only felt disgust at Josh’s manhood, but regardless he gently extended his tongue to lick his cockhead. He grimaced at the salty taste of the cum and gently swirled his tongue around the glans. It was a taste he could never get used to. 

“Mmm fuck Dad, you’re hungry for a load aren’t yah,” he said cruelly, grasping his fathers hair roughly as he prepared to ram his shaft deep into his dad’s throat.

"Mmmmmph," Mark replied in disdain, but opened his throat to allow his son deeper access.

With a rough thrust, all eight inches of his member slid down his fathers throat. With a rough slurping sound, his cockhead struck the back of his fathers throat, causing him to gurgle with discomfort. His low hanging nuts smacked against the older males chin gently. Mark had no gag reflex, making him a perfect cocksucker. 

Shuck, shuck, Schlick, slick,

A cacophony of wet noises filled the room as Josh gradually began to increase the speed of his thrusts. He locked eyes with his father, reveling in the pained expression in his eyes and enjoying how the muscular stud kept his mouth wide for his pleasure. 

Josh glanced down at his fathers package. His swollen nuts were distended onto the floor, enticingly plump. His dad’s massive cock was entirely flaccid from the sensation of cock sliding down his throat, and it jiggled languidly with every rough thrust down his throat. 

“You enjoying yourself their pops?” Josh grinned widely, enjoying the sensation of his father's mouth.

Josh chuckled at the sight and arched his sole over his fathers left nut. He began to tap his toes methodically into the bruised flesh of his fathers especially damaged left nut and with each gentle probe of the organ Marks cock began to twitch with pleasure. It began to spring to life once again, rising out of the way and allowing Josh full access to crush his doomed nut.

Tap, slick, tap, slick, tap, slick, tap, slick, tap, slick, tap

With each light palpitation, Josh forced his cock deep into his father’s throat. Josh’s toes gently pressed into the bruised nut flesh that was lying distended in the ground like a bruised mango. A light sheen of precum made the surface of each organ slick to the touch. Josh marveled at how easy the testicle dimpled under the light pressure of his toes, it’s swollen mass distorting easily compared to its usual toughness. It felt mushy under his foot, and as Josh gradually increased the pressure he could feel the beleaguered organ oozing between his toes. 

“Mmmmmph!” 

Mark squealed as his already damaged nut was subjected to further abuse. Without a doubt there was already permanent results from the previous strikes and if they were to play any further he’d be shooting blanks permanently. With each cruel probe of his jelly-like huevo, Mark could distinctly taste a salty spurt of baby batter leaking down his throat as his son was obviously enjoying the sensation of his dying nut oozing under his toes.

He gurgled in displeasure.  The combination of cum eating and testicle crushing was causing him severe nausea, such that it took all he had to avoid vomiting.

“Damn Dad! You like that, huh?” Josh crooned, seductively,  bemused by the impressive erection that was now smacking against his kneecaps with each aggressive thrust. 

Marks cock was harder that it ever had been. It was so swollen with blood it hurt, now almost ten inches in length now and pulsing violently as his lefty was crushed. Thick spurts of precum fired from his cockhead continuously as the sensation of his nut imploding under his sons command was akin to continuous orgasm.  Without a doubt it was one of the most impressive manhoods in the world, but for the owner it only served as a piece of meat for torture.  This top percentile cock, on a top percentile stud of a man, was potentially experiencing it's final erection.

Thuck, Thuck, Thuck, Thuck

Josh sunk his toes deeper into the doomed testes, his toes coming off the organ sticky with cum as the unending stream of precum continued to ooze onto his fathers ballbag. Each cruel palpitation smashed a different portion of the oversized huevo, and Josh could now feel the organ breaking down. His left testicle resembled a lumpy orange now, while his right ball was the size of a large lemon and bruised black and blue.

Thuck, Thuck, Thuck, Thuck

“Fuck dad, should I take it right now? It feels so mushy! Like I could pop it right now...” 

Mark's cock twitched and he nearly came from the threat alone, his eyes were fixated on his sons face and no longer pleading for mercy. It was his place, his responsibility on this earth to provide his equipment for Josh’s pleasure. The agony in his loins and increasing lightheadedness was undercut by this desire. Right now, he wanted nothing more than for his nut to burst under his sons foot and he shifted his body to allow a better angle for it's destruction. 

Thuck, Thuck, Thuck, Thuck

Josh began stomping onto the squishy nut, smashing the organ against the floor brutally.  He was careful to never allow the organ to plump back into shape after each strike, forcing his toes deeper and deeper into its depths.  Josh could feel a truly massive orgasm growing in his nuts as the pancaked ball began to break down under his weight. 

"Pwwweees!" Mark squealed, his voice obscured by the thick cock pounding down his throat. His eye's pleading.

Suddenly, Josh forced his cock all the way down his throat and shifted his weight, attempting to balance his body on the squishy organ. With trained core and leg muscles, he was able to successfully stand on the ball effectively splitting it in two as the bulbous organ attempted in vain to compensate for the 190 pound weight now attempting to snuff it out. Mark's eyes went wide as his nut was torn under the pressure.

Squick 

Josh felt something give slightly under his toes and came explosively from the sensation. He leaned all his weight into the fracturing organ and began pounding his fathers face with his cock. 

“Fuuuuuuuuuuck!” Josh screaming as he orgasmed harder than ever before, uncontrollably smashing his cock down his fathers throat. Load after load of thick cum fired down into the muscle stud’s belly as he experienced the greatest orgasm of his young life. Josh then pulled his cock from his fathers throat to splatter his father’s handsome face with the remainder of the massive load. Thick splats of babybatter peppered his fathers face, which was agape in shock as his brain attempted to process the sensation emanating from his loins.

Mark's entire body was frozen in place, muscles straining.  Before his brain could react to the feeling to a broken testes, his cock responded to the nutting, firing a load unlike anything Josh had seen before.

Splat, Splat, Splat, Splat

Josh stepped back off of his dad's ballbag in surprise as warm wads of semen arched up to his chest, coating his impressive pectorals with thick babybatter.  As he removed his foot, he briefly observed a noticeable dimple in the massively swollen organ and it no longer plumped into an oval shape at the release of pressure. The sudden influx of blood to the damaged organ caused Mark to orgasm even harder. Drops of cum were flying across the room and his cock was twitching so aggressively it looked like it was about to snap off his body.  Thick rivers of semen shot up all over the muscular studs body, sticking to his thick body hair.  

Finally, the nearly endless flow of cum seceded and Mark's eyes rolled into his head, his body overwhelmed by agony as the waves of pleasure subsided. With a loud thud his heavy muscled body came to rest before his son, coated his his own juices.

“Oh shit! Dad!” Josh yelled in genuine concern, the waves of orgasmic bliss subsiding.

Josh dropped to his knees, panting and spent. Gently, he rolled his fathers heavy frame onto his back to get a better view of the damage.  The limp muscle stud fell lightly onto his back over the semen covered floor and his legs parted naturally allowing Josh full view of his work.

The sight between his fathers sculpted quads caused Josh’s wilting cock to stir despite itself. Where his Dad’s proud manhood was affixed to his body was a black and purple mass of swelling flesh that could hardly be recognized as male genitalia. Mark's lofty shaft, which typically hung five inches flaccid, was obscured nearly entirely by his fathers bloated ballbag, which jiggled languidly at light prodding from Josh's curios fingers. 

Josh plunged his hand into the mass of damaged flesh, noting his fathers lack of response, blissfully unaware to the probing. Expecting a pulped testes, Josh was pleasantly surprised to find a mostly whole testicle within the mass of swelling. He couldn’t help but apply a little pressure to the distorted egg, marveling at the ease of compression and spongy like texture. 

Incredibly, the seemingly ruptured nut was attempting to regain it's shape.  It plumped awkwardly into a lumpy oval shape as Josh released his grip, indicating the nut was mostly still whole despite all odds.

Josh glanced down at his cock, which was erect once again from the sensation of the broken nut, and smiled. He grabbed his iPhone, positioned his swollen member into the frame cockily, and snapped several photos of his Dad’s ever swelling sack, knowing that his father would want to see the results later. 

Josh’s mind was racing, already planning their next session and how to take his father out of the gene pool. He grinned widely, and surveyed his father’s slumbering frame. 

It was going to be a very long week for both of them.
