The evil, mad scientist has been working for decades to perfect a serum that enhances male virility, and he has finally perfected his formula with Testicle Blaster 9000. This serum increases a man's virility a thousand-fold, making his gonads churn out sperm cells at an incredibly accelerated rate.
The effect on a typical male was nothing short of awe-inspiring, resulting in a dramatic increase in spunk production. Unfortunately, the serum's effects were so pronounced that its use inevitably resulted in one of two conclusions -- either the man's heroically overworked bollocks would overheat and literally burn out, or they would produce sperm even faster than could be ejaculated from the man's cock, causing his gonads to steadily swell until they reached critical limits...at which point they exploded.
With his serum perfected, the mad doctor decided it was time to use his secret formula on the massively muscular Marine that he had captured trying to infiltrate the secret laboratory. The handsome muscle giant was like no other man the doctor had ever seen before, and he was also blessed with what had to be the most gargantuan set of cock and balls on the entire planet. Here was the perfect test subject for his perfected formula.
The handsome hunk proved to be far stronger and tougher than the evil scientist could have ever dreamed, enduring ever larger injections of the serum directly into his balls, and pumping out truly mind boggling amounts of prime G.I. jizz. After a full week of gradually accelerating experiments, the excited doctor decided to go for broke, and injected ten times the previously lethal dose into each of the young muscle man's mammoth bollocks.
The results were as predictable as they were spectacular.
The handsome soldier's already enormous bollocks swelled larger and larger still as they started producing sperm at a truly ferocious rate. The mighty gonads turned a dark red color and were actually scalding hot to the touch, as they each began producing more than a gallon of ridiculously thick and clotted spunk per minute! Even his colossal fuck cannon could not keep up with that pace of spunk production, and his jizz factories started swelling faster and faster.
The end was inevitable.
The mighty warrior's bulging and bloated right bollock proved to be the weaker of the two colossal gonads. Cracks began to form in the unnaturally thick wall that surrounded the precious sperm-producing flesh in the heart of his testicle, and it was clear that his mighty orb would not be able to hold its shape and integrity much longer. And sure enough, with a loud and very wet explosion, his gargantuan right balls burst open under its ferocious internal pressures, spraying overripe spunk and chunky nut guts more than a dozen feet in every direction.
To speed up the end, the doctor simultaneously injected a double dose of serum into the young Marine's failing left bollock, knowing that it too would shortly follow its brother in spectacular annihilation...
