I was 14 at the time and I was walking in the woods with my best friend Emma. I really had to poo so badly and when I told her Emma she said she was desperate to go as well. We kept walking for a while until Emma stopped suddenly. She was bright red and she whispered in my ear, "I'm pooing in my knickers. You won't tell anyone will you?"
I replied, "I won't if you don't tell anyone I'm doing it as well!"
I pushed and filled my knickers with a very relieving poo while I watched Emma filling hers. After we finished we swapped our soiled knickers and walked home with each others poo all around out bums.
