Twenty year old twins Paul and Scott had a special birthday present lined up for their little brother, Jimmy. Jimmy had always been the runt of the family and the two muscular jocks had been bullying and antagonizing him for as long as Jimmy could remember. Their parents had dismissed the handsome twins' bullying as typical sibling rivalry, mostly because Jimmy had been terrorized into hiding the worst of the abuse from anyone lest his sadistic older brothers lash out at him even more.
It was the night of Jimmy's eighteenth birthday and Paul and Scott easily overpowered their scrawny brother and tied him to his bed spread eagle, his arms tied to the head posts and his legs wide open with his ankles tied to the foot of the bed. Jimmy screamed and begged as his maniacal brothers looked down at the massive orbs resting between his slim toned legs. The terrified teenager's eyes grew huge as Paul and Scott, who were standing on either side of him, pulled out two large rubber mallets with their eyes locked on Jimmy's overgrown ball sack. What Jimmy lacked in physical fitness he more than made up for between his legs; an immense bag packed with a pair of heavy virgin nuts and a fat cock the twins had seen grow nearly nine inches in the shower. Jimmy's beefy double lumps were obvious even when the timid young man tried to hide them with baggy pants making them his brothers' favorite things to beat on. It satiated their barely constrained sadism whilst letting them explore their burgeoning interest in ball busting in a consequence-free way. Consequence-free for them, at least.
"You know, Jimmy, now that you're officially a man, I think we oughta' give you a little test..." Paul sneered as he gently beat his mallet into the palm of his hand.
"Yeah, we're gonna' see how tough these freakishly huge nuts of yours really are!"
Jimmy begged his brothers as they callously lined up their mallets, one each hovering over Jimmy's defenseless young nuts.
Although the brothers’ faces were always animated with cruel excitement whenever they tormented Jimmy, this time they were especially excited, not even doing a countdown to let Jimmy wallow in fear before slamming their mallets down full force onto his nuts. Jimmy let out a wail of agony as his swollen spuds were mercilessly flattened into his pelvis.
Jimmy’s pulled against the ropes in an instinctual reaction to the overwhelming agony. He tried to focus on a single detail in the room—a stain on the ceiling, a poster on the wall—anything to pull his mind away from the white-hot agony pulsing between his legs, begging that his brothers would finally stop. Despite Jimmy’s frantic thrashing, the twins’ knots were too good and all of Jimmy’s flailing barely did anything to keep his nuts out of range.
The brothers chuckled and joked as they brought their mallets down over and over and over into Jimmy’s fresh sack. Jimmy’s huge testicles were being pummeled nearly flat after each unhinged, ruinous blow and his muscular brothers weren’t holding back an ounce of strength and Jimmy’s balls were quickly losing the battle.
“They say teen nuts are supposed to be the strongest,” Paul joked.
“Well we’re about to see!”
Jimmy screamed as he felt his tough nuts finally reach their breaking point. The enormous organs were being crushed rapidly nearly flat over and over with zero reprieve. Even after being toughened by years of abuse by Scott and Paul, this session was more than Jimmy's nuts could handle! Jimmy hysterically tried to get free which only made the twins more determined to give Jimmy his big present.
Paul and Scott were frantically trying to see which one of them was going to knock their undersized brother out of the gene pool first, swing after swing methodically wore down the delicate internal structures of his fragile young sack, each over-sized testicle rolling and compressing in a desperate attempt not to pop.
“I wonder which one bursts first?” Paul mused.
“Burst!?”
Jimmy’s eyes went wide as he suddenly realized this wasn’t a typical session. He pulled hysterically at the ropes while his nuts were pummeled permanently flat.
“Let’s make a bet! Let’s see whose splatters the furthest!” Scott laughed.
“Hell yeah, like with that soccer player!”
The brothers’ were grunting in exertion, each one taking deadly aim at his assigned nut. Jimmy’s bag was an enormous purple and black mound of flesh that looked like it was going to rupture at any moment.
CRUNCH
“Oooooo!”
Jimmy screamed as his right nut cracked.
Jimmy’s oversized teen testicle couldn’t resist the nonstop impacts and its tough fibrous outer membranes shattered, spilling the inside of his bag with unspent jizz and broken nut innards.
His left nut didn’t last much longer before its beefy shell didn't just crack. It caved in. Jimmy’s eyes crossed as he felt his nut implode, a permanent mallet-shaped indent in his busted sex pod. But the brothers didn’t stop, they had a bet to settle.
Jimmy’s unused virgin nuts were pounded into meaty pieces, then smaller chunks, abused without limit until they were literal sack sauce, the nearly comatose teenager barely flinching as the room was filled with the wet impact sounds of rubber on flesh. The contents of Jimmy’s bag had been thoroughly destroyed but that only made Scott and Paul more determined to see how big of a mess they could make out of their little brother’s manhood.
What was left of Jimmy’s right nut was the first to go. Paul cackled as the right side of Jimmy’s bag split open and a jet of teenage procreate slurry rocketed out splattering his thigh.
“Do yours now!”
Paul was egging on his twin as he unleashed the final fateful blows into the left side of Jimmy’s flattened manhood.
SPLAT
Jimmy’s eyes crossed as a gory wave of tendrils and chunks splattered out the left side of his blown open scrotum and landed with an audible wet splat on the wall behind Scott. The two brothers looked at the gooey stain that was slowly oozing down the wall incredulously. They had known Jimmy’s sack was fat but had no idea his bloated nuts had so much pent up pressure.
They gave Jimmy’s ruined nut sack some final strikes, delighting as more and more of its insides splattered out.
“Happy birthday, Jimmy!”
Scott laughed as he used his gore-covered mallet against the side of his kid brother’s face, instantly knocking him out.
