I drank a ton of water and held it as long as I could. I'm bursting and desperate to pee, wearing nothing but white panties. I dance around in the tub for a minute or two, trying my best to hold it before exploding piss. It drips down my legs and soaks my panties. I turn around so you can see from all angles. After I finish pissing, I rub and show off my wet panties.
