Have you tried playing this games "sister" game Trials In Tainted Space? You can have like 100 balls the size of the moon there that have enough nut butter in them so that you could potentially cum out the sun. Usually the game would make it so that it is impossible for your character to move around because of their sheer gargantuan size, but one of your companions actually let's you buy a pink hoverboard for girls that you can ride around on instead then.
Doesn't matter if your scrotum is near reaching critical mass and turning into a black hole. Pink hoverboard bro is here to save the day and completely ignore your ball god given immovability.
(The game hard crashes when the cum output of your balls reaches a certain number (xⁿ). If I remember correctly it was when n got somewhere at around and above 30. But for me it was well worth finding out.)
