hi there,
there arent many popping drawings out there, not even many ballbusting drawings. The most poppingpictures I know are from Knave/EM, you can watch them on his wooonderfull blog He even got a comic with ball rupture ending. A group of girls try to pop his balls, and at the end, they make it

I just saw that nearly all of his comics got popping balls. Most balls pop in Self Defense Night
And Babel got also many Ballbusting drawings. Not a real popping one, but always very clooose!
