Cadence takes on the challenge of holding her pee as long as possible and then peeing into a graduated cylinder to see how much she was keeping in her bladder. As is the way of these challenges, cadence seems fairly relaxed at first, but she has been pumped full of liquids and it is not long before the squirming begins. Squirming turns to outright desperation, and several times Cadence reaches for the cylinder, but she is not no, that she must wait a little longer. The struggle is now really on and she fights the urge to release, difficult at the best of time but excruciating when naked. Only when she declares, "I'm going to burst on the floor if I don't do it", is she allowed to pick up the cylinder and relieve herself. That look of immense relief and those sighs of dispersing tension are always a satisfying end to a long wait.
