Underwear pooping 😍

Hello, I had the urge to poop in my white underwear today. I went to bathroom pull down my pants and starting unloading a big mushy poop into my white briefs. My briefs were so full with my big warm poo. My white briefs sagged between my legs and had a big brown stain on the back of my underwear. The big poop felt so amazing 😍😍
