I was walking home from work last night and I was desperate for a poo. I'd been holding it all day and I was struggling to hold it and as I couldn't see anyone around I thought it great fun to do it in my knickers. My heart was racing with excitement but I was nervous about doing it in public and I had to hold it while I tried to decide what to do. I was getting more and more desperate and I thought what the hell and pushed. I peed my work pants as I felt my poo coming out into my knickers and it felt so good I just kept going. I filled my knickers and the relief of it was so good I didn't care who saw me.
