Gagged and pissed

Liked how the pants got wet and she had a nice amount of pee.  The thing I don't quite understand is once the pee has started to flow and there is no hope of access to a toilet, why continue trying to hold?  The pee is coming and there's nothing that can be done about it.  Might as well accept the fact that your pants are going to get wet, despite the efforts, and just let it flow.  You will feel much better.
