Most days I am at work alone, what usually happens is I take a hair band, (a cloth covered hair thing that women use to put their hair in a tail), making a figure of eight, I put my low hanging balls in the bottom half and my cock in the upper half. I wear this for about two hours, all the while reading stories on Solo Touch, and/or start downloading porn over the internet.
I try and take about two hours of working my cock through my pants rubbing all the while, this hair band is tight around my cock and balls. When I have to answer the phone or help a customer my cock gets soft, (most times) and then I resume my reading or watching porn while rubbing.
When I am ready and cannot take it any longer I lock the door and put my sign up, 'I'll be right back.'
I go into the bathroom and rub my cock. It feels great with my cock being kind of restricted and I can feel all my veins and my cockhead which is so big I can't stand but five or ten minutes of jacking my cock before I cum all over.
