The concept here is that a group of construction workers have ganged up on their co-worker Jake. The big man is supremely muscular, roguishly handsome, and phenomenally hung, and the other construction workers had grown extremely jealous of the huge stud. They decided to end his reign as an alpha male permanently...
The handsome hunk was strung up in heavy chains and hauled high up the scaffolding on the newest high rise. Jake's titanic bull cock has long since been galvanized into steely hardness by all of the rough hands mauling his magnificently muscular body, and his colossal cajones are churning with a full day's worth of thick baby batter. The cruel blue collar men decide to destroy the most obvious symbols of Jake's awesome masculinity -- his mammoth cock and balls -- in the most painful ways possible.
Thousands of big metal rivets still need to be hammered into place by huge mechanical pile drivers, and the angry construction workers decide to use big Jake in the hammering process. Jake's co-workers manipulate his massive cock and pendulous balls so that they lie in the path between the pile drivers and the rivets, and then turn the hydraulic-powered pile drivers up to full blast.
The jealous construction workers fully expected Jake's genitals to be pulverized into liquid ruin by the very first strike of the pile drivers, but they didn't count on the super human power and toughness in the big lad's mighty man meat. The stud's bullish cock and balls endure blow after blow after annihilating blow, plumping back after each brutal hit. Even more amazingly, the power of each blow is transferred to the rivet beneath the man's incredibly tough flesh, driving the rivets all the way home into the massive steel girders.
The rhythmic and beefy smack of steel-on-meat goes on for hours into the night, the big bull stud enduring abuse that would have destroyed another man's genitals a thousand times over. The big hunk just endures it all stoically, occasionally grunting in pain and thrashing about uselessly in his unbreakable chains. He's also blown nearly a dozen utterly mammoth loads so far, each impossibly voluminous load containing more sperm than another man could produce in a month of steady milking. Jake was just further cementing his status as the greatest stud that any of these men had ever seen.
As the merciless punishment continued, however, it was clear that the relentless hammering of his colossal genitals was starting to take its toll. And as dawn neared, it was obvious that Jake's cock and balls couldn't take much more. His once rock-solid cock had grown puffy and mushy, covered in angry bruises and squashing more than halfway flat with each new hammer blow. His magnificent bollocks appeared to be in even worse shape. His massive sex glands had started out the day like a pair of huge boulders, so dense with ferociously tough nut meat that the pile drivers could barely compress them even a single inch with even their most powerful blows. Now, the pile drivers were able to sink so deep into the heavily traumatized testicular tissues that barely an inch separated the face of the pile driver with the tops of the rivets. The massive and swollen orbs had grown so dark red that they were nearly purple. Worse still, small tears were appearing in the much-abused scrotum, revealing the heavily mauled ball meat beneath.
Yes, it was only a matter of time before Jake's mangled genitals finally burst under the cruel and continuous assault, splattering the huge metal girder with the remains of his once magnificent manhood. It was also clear by the young man's increasing grunting and groaning that he was nearing yet another awe-inspiring orgasm, so it would be a race against time to see if Jake could blast off one last orgasm before his mighty cock and balls were crushed into a useless paste of raw procreative material...
