When I was 15 I had a best friend called Emma and like me she was into pooing. At the time I'd never done it in my knickers with her around as I wasn't sure what she would think of me but we'd regularly poo in the woods together. Well one afternoon we managed to get some cheap cider and we were getting drunk by the river. I badly needed a poo and I'd been holding it all morning. Well not exactly all morning. In fact it had been 3 days since I last went so as you can imagine I was desperate. I told Emma about it and completely out of the blue she suggested I went in my knickers and being drunk I did. I stood in front of her with my knees bent and just pushed filling my knickers completely. It was a huge relief but messy. I had to take my knickers off and wash them out in the river but I did get them clean and put them back on still wet.
