Master's Nut Popping Day

Leon

Leon stood obediently in the middle of the damp, stony basement wearing only a tight white T-shirt and a pair of white boxer briefs that hugged his modest package.  A thick rubber ring wrapped around the base of his scrotum made his full, large nuts bulge forward creating an obscene double bulge between his legs.  He was standing with his legs spread wide and his zip tied hands crossed behind his back. Master had been in an usually bad mood all week culminating with him knocking Leon's breakfast fork out of hand and ordering him into the basement where he was instructed to stand until further notice.  That had been hours ago and Leon was beginning to wonder ...

Master's lumbering, muscular frame shook the stairs as he stomped down the basement swearing into the air.  He's really in a bad mood, Leon thought, desperate to do anything to help.  Master was carrying something small and white in his hands and before Leon could see what it was it was being crammed into his shorts!

The movement had been so rapid it took Leon a moment to realize he was wearing an athletic cup.  Master, wearing only a pair of bright yellow shorts, stood in front of Leon eyeing him up and down as if contemplating what to do next with a toy.

"Against the wall! Do it!" 

Leon stumbled backward and as soon as his back hit the wall Master dove to the ground and secured Leon's ankles to wall with shackles. The handsome man was now standing with his legs spread, arms behind his back and being stared down by his towering Master.  

"Oomph!" 

Leon was winded as Master's enormous fist slammed into his toned abs. Again and again without warning.  Leon doubled over and Master sneered as he darted off fetch something from a basement shelf.  He came with a U shaped metal object that gave Leon both delight and terror.  Master proceeded to secure Leon to the wall by the neck, totally immobilizing him and allowing him to only move his head slightly.  Any attempt to double over now would cause Leon to literally choke himself.  

Satisfied with his work Master knelt, reared his fist back and sent it sailing into Leon's crotch.  He winced out reflex but the blow was totally deflected by the athletic cup,  Master's huge fist pounded the cup several more times connecting so hard that the vibration, though sparing his junk, was causing his muscular thighs to tingle.  Leon was glad he was wearing a cup because if Master had been going to town like this on his bare balls...

Master continued sparing with Leon's crotch until he had developed a light sweat and his own thick tool was tenting in his shorts.  Leon couldn't help but admire Master. He was an Adonis, a muscular alpha male with a devil-may-care attitude and massive cock to match.  Master's cock looked truly enormous jutting out like a pole from his body and Leon's mouth literally watered thinking about being violently skull fucked after Master was done.

Master snarled and lumbered toward a shelf, coming back with a broad smile on his face.  Leon smiled back.

"Guess what? It's nut punching day, mother fucker!"

Leon's eyes grew wide at the venomous tone of the remark and before he could recover Master was slamming his fist once again into Leon's crotch. Only this time the blows felt much more solid.  Master's heavy fist was a blur, piston punching the cup so hard that Leon was sure it was going to break.  

"Oh yes! Fuck Master!" Leon screamed as he realized Master was wearing a pair of thick brass knuckles.

As if Master's own bearish strength wasn't enough now he was literally working up a sweat pounding away at Leon's crotch with heavy, sharpened metal knuckles.  Master was grunting and his eyes were glossed over as if he was in an erotic trance.  Only a thin layer of fabric and plastic was stopping Master's fist from colliding...

CRUNK

"Break mother fucker!" Master growled.

Master was really going to town, leaning in all of his beefy frame into each blow.  Leon was breathing hard, for the first time genuinely frightened that the cup was going to break.  Master kept pounding putting hundreds of pounds of muscle into each blow.

CRUNK

Leon was panting heavily.  His thighs had to be bruising from the impacts but the cup was holding on.

"Break! Break!"  spittle flew as an animal like Master continued to pound the cup until, suddenly there was an almost glass-break like 'crack'

"Oh Master..." 

Leon couldn't finish the sentence as Master's fat fist sailed into his crotch.  This time the shattered cup, though not totally broken, offered markedly less protection.  Each fist strike was met with the sound of more plastic shattering.  Leon could only watch in fascinated horror as Master was able to lay down punches to quickly that, somehow, his hulking frame became a blur.

"Ooooh!"

The cup was lost most of its shape by now, and the center was starting to cave in on Leon's balls.

"My balls! Master!"

Master stopped for a moment and stood to face Leon, his sweat soaked face in a wicked smile.

Master's cock was still raging and he was eyeing Leon's beefy frame with lust.  Leon was sure the game was about to end and was going to be impaled by Master's foot long ass wrecker right there in the basement.

 Leon had been so caught up in his fantasy that he didn't immediately notice that Master had resumed his position, slightly squatting to put his fists level with the target.

"Master!"

"It's nut popping day mother fucker! Fuck! Fuck you!"

By now so much of the cup was broken that the outline of Leon's balls were once again plainly visible and shards of the cup caused jagged, random protrusions in his shorts.  Master drew his fist all the way back and sent it sailing full force in Leon's defenseless nuts. 

Leon attempted to double over but only ended up gagging himself as his neck restraint held firm.

WHOOSH!

Master was delivering the same ferocious, metal-knuckled, full-body-power blows into Leon's balls so quickly they might as well had been speed bags. Leon thought he was going to vomit and his eye rolled backward in his head.  He was screaming in a baritone, constant drone that only seemed to make Master's cock twitch.

Master was relentless and Leon's balls were quickly swelling creating enormous double lumps, their roundness acting like a rage trigger for Master.  During all the jostling Leon's dick became inexplicably excited despite the agony coming from his nuts.

SPLRRUNCH

"Fuck yeah! Hell yes!"

Master's fist had collided with Leon's hardening dick at an awkward, unfortunate angle.  Leon's sperm sprayer was permanently out of commission after the brass knuckles - and hundreds of pounds of force - caused the half inflated organ to sport a permanent fist-shaped indention. Blood that had just been pounded out of the shaft rocketed into Leon's cock head backing the mushroom expand so much that it was clearly outlined in his shorts.  Despite his writhing and futile attempts to escape in the back of Leon's mind he was weirdly excited for what was about to happen.

Master's fist might as been a mallet. Leon's testicles were barely keeping their shape as membranes and tubes started caving in on themselves inside his bag..  His permanently inflated cock head was unceremoniously flattened so violently that there wasn't even a hint of a bulge there.

"Pop for me! Come on babies, pop for daddy,"

Master kept wailing on Leon's nuts until the right one finally popped open, spilling its contents into Leon's rapidly swelling sack.  By now the hideously swollen lump in Leon's shorts was too much of a target for Master and he he laid into it, pounding it mercilessly until Leon's left nut cracked completely.  Leon's sack didn't have a single whole nut by that wasn't stopping Master!

Leon was gurgling, barely conscious, only occasionally letting out a castrato yelp.

"Fucking get flat! Flat!" 

Master roared in lust and anger as he attempted to permanently flatten the lump in his toy's shorts. It didn't take long before the contents of Leon's sack were so thoroughly pulped that - after Master's final punch lifted away - Leon's crotch barely registered as a bulge.

Master was panting as sweating, roiling with rage that there any lumps at all.

He ripped off his shorts and stroked his massive cock with one hand as his other fist just pulverized goo.  After feeling a particularly meat lump explode under his fist, Master reared his head back and let off jet after jet of sperm even while he continued pounding.  

Finally, convinced that Leon's entire package was thoroughly destroyed, just pulp that would come spilling out as soon as those shorts were pulled off, Master stood to his feet. 

Leon had completely blacked out though a look of sick satisfaction was etched across his face.

"Fuck, I broke another one,"  Master chuckled as
