Love to Shit Girls - Poopy Huge Panties

Ive done it again, but this time Ive filled two pairs of panties with a huge load of poop. Doing it every day like I do, I often run out of panties, as many of them are too far gone to wash after Ive had my dirty fun in them. The shop assistant where I buy my panties recognizes me every time, and I often wonder if she ever questions why I buy so many pairs of panties. Shes never said anything, but I bet she wonders why. Id love to just tell her that I need them because I love to shit myself!!
