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 dri n k ing 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!
