Wetting Myself on Phone to step-daughter

Custom - I am in the kitchen cleaning in my undies and stockings. I get a call from my step-daughter. She has accidently wet herself while she was out and is embarrassed and wants to come over to clean up. We discuss different times we have both been accidently been caught short and in the mean time I don't realise this talk of peeing makes me need a wee and I accidently pee myself.
