I was 15 at the time and I was walking in the woods with my mate when I had to poo really badly. I felt embarrassed about telling Emma and I kept quiet until she said she had to s**t so badly she was about to do it in her knickers and I admitted I did too. Emma asked me if I'd mind if she did it in the woods and I said only if I could join her. She pulled her jeans and knickers down and squatted right in front of me and she peed like a racehorse as a pile of poo formed under her bum. Seeing her go like that made me want to go even more so I wasted no time in pulling my jeans and knickers down and I pood my brains out as Emma watched. I peed a little bit. The thing is I got a big turn on seeing Emma take a poo and by the way she kissed me I think she did too. The next thing I knew were were making out together and I came to a shuddering climax followed by Emma.
