Hi Dave nice to see you smiling,
As something a little different Dave would you consider one of the models (with their consent and you of course filming it,) giving a running commentary on her desperation with a one to one with you as she begins to feel the need to pee having had drunk an amount of fluids.
She could tell us how she is feeling at that precise moment and whether she is using her sphincter muscles and how often she is having to use them giving a rating of 1-10 at what desperation she is at at this stage. Also if she feels the need to cross her legs while standing or sitting down, and if it would make her feel more comfortable if she were get up and walk round or place her hand in her crotch either while standing up or sitting down. Then the final moment when she as to pee.
