Panty pooping girl

Hi my name is Emma and I like to poo my knickers on purpose.

Since my first "accident" I haven't had the opportunity to do it for a while but last night I decided to make my own opportunity. I decided to wait until after school and do it in the woods so I took a toilet roll from the bathroom and some spare knickers to school with me and hid them under the school books in my bag and left for school. I was already feeling the need to have a poo when I woke up and by lunch time I was busting to go but I held it until home time. During afternoon lessons I was getting a bit desperate and I had to clench every so often to keep control. By home time I was properly desperate and when I stood up from my desk to leave class I nearly had an accident in class but I clenched really hard and managed to force the turd back in. The walk to the woods was exiting. The thought of pooing myself outside was a huge turn on and I was creaming my knickers just thinking about it. When I got to the woods I was nearly pooing myself but there were some people around and I was scared someone might see so I had to hold it until I found somewhere more private. That was a bit of a challenge because I was fighting a battle with my bowels to keep it in and I found my predicament even more exciting and I was tempted to risk it and have my accident right on path. No one was that close anyway and I figured I could probably get away with it if I acted normal. My heart was pounding with the excitement and I was too desperate to think properly and I found myself peeing into my knickers. I forgot I had to do that. As the hot yellow liquid ran down my legs I relaxed my clenching and I felt a bit of poo coming out which made me want to cum! I don't think anyone noticed what I was doing but I felt my face burning red with as I started to push without thinking. I felt relief straight away and I didn't care who saw me now. I just wanted to fill my knickers with a big dirty poo and I kept pushing. I peed for about thirty seconds and after about 4½ minutes I finished my poo. My knickers sagged under the weight of my poo some of it was hanging from one of the leg holes. The last of my pee was dripping off it and I couldn't believe at sixteen years old I'd totally pood and wet myself and I was so horny I wanted to finger myself but I couldn't do it knowing I might get caught. I couldn't even clean myself up and I had to walk right into the woods before I found somewhere really secluded. I had a final look all around to make sure I was alone and I carefully​ slid my knickers off trying my best to avoid getting any poo on my legs but I wasn't very successful. Once they were off it was time to start the cleaning up. My legs had a few brown streaks on the back of my knees but the real mess was between my bum cheeks and I used up a lot of the toilet roll to get everything off. I had a final pee on top of my pile and took care of my incredibly aroused state. I sat down on a fallen branch and pushed two fingers inside my most private area and and as soon as I touched my g spot I came so hard I had to cover my mouth to avoid making a noise. I made my whole hand all wet and sticky and I had to rest for a for a couple of minutes to catch my breath. I cleaned up after that and put my spare knickers on before going home and no one had a clue about my dirtiest deed.
