Desperate Outside Tummy Hurt Panty Poop

I have been loving the nice weather walking outside, but now I have a terrible tummy ache. I run until I find a good spot, looking around making sure no one can see me. My tummy is cramping and I begin pooping right into my white undies. I cant believe I couldnt hold it until after my walk. I take off my poopy panty, wipe my ass, and then leave my dirty panties outside in the woods. I run away thinking of a stranger finding my panty I left full of poop!
