You poor little thing, it has to be so hard being locked in that cage and never knowing when you can get free. You try to get so hard, but that cage is too tight and you are not allowed to take it off. You need to cum because your balls are so full. You need that release, don't you? You are in that cage indefinitely, so you need that release. You are going to leave the cage on, but you are going to jiggle it until you cum. You need this, you need to be let free but you aren't allowed to take it off. You need to empty those balls, this is a little loophole. You aren't taking the cage off, so what have you done so wrong?
