I'm already at 8/10 bladder capacity and I keep holding and filling my bladder. When I'm at 9/10 I masturbate until I cum and then I keep holding, but my bladder is already too huge and full, so even though I put my hand between my legs to help me hold it, I still have leaks and there's one leak that I just can't contain, so all my pee ends up coming out of me and wetting my panties.
