In the pub, sat around the table with your friends, you were desperate to pee. You tried to relax, staring into the middle distance, focused, thinking about running water. They'd suddenly address you though, and interrupt your focus, even the patter of their voices put you off as you discreetly squirmed.
"I'm just nipping to the bar", you told them, getting up, brushing the back of your skirt down, scared in case it caught the chair and revealed your secret.
As you waited at the bar you tried again to relax, you leant against it which allowed you to squat slightly and discreetly, you spread your legs a little, bent them slightly at the knee as you tried to relax and let it flow.
That's when the first drops appeared, you felt their wetness against your lips, warm and satisfying. This made it easier and you started to gush. Then the barman asks, "what can I get you?"
