Today's challenge is that Kate need to pee sooo badly, but she will hold it and resist for 10 minutes. During this time, she keeps having further water. At the end of the 10 minutes she is only allowed to pee over 100 mls, fill a glass and then stop. Her pussy hurts from the pressure but she has to live up to the challenge. So she squirms desperately in a growing expectation of each point of release, trying to forget about the pressure. When the time comes, she is happy for a little while, then becomes desperate again as she cannot release everything... She pees for more than 5 times during almost one hour, until she cannot hold it any more... At the end of the challenge she peeing a lot till her huge bladder is full
