Even I'M not sure what the entire story is behind this particular image.
I wanted to draw a captive stud who is having his huge balls literally pumped full of growth hormones and nutrients, forcing them to painfully bloat and swell to staggeringly massive dimensions as their sperm-producing capacity is cranked into overdrive. The supremely dense and tough ball meat is straining valiantly to contain all of the thick and chunky fluids sloshing around inside of them, but even this stud's titanic testes cannot hold out much longer. Those behemoth bollocks are approaching critical mass, and if something doesn't happen soon, they're going to explode in a gory mass of sundered ball flesh and gallons of raw sperm!
Let me know in the comment section below what you'd like to see happen to this hapless young bull.
