Unable to believe that her last two measurement volumes have been below her own record, Carissa is very determined to turn things around this time. She plans to wait until she feels she is about to burst before pulling down her panties and peeing into the cylinder. She struggles so hard to hold her pee, delaying and delaying to maximize her capacity, until she is frantic in her efforts to not lose control. Whatever the outcome, it's always good to watch a very desperate woman having to wait!
