Ive done a massive poop in my white panties. Watch them go from clean and white to filled and dirty, as the poop bulge grows in them and I sit on it and squash the poop and make a mess. Who likes to have a big bulging mess in their panties? I do! I like it a lot, and I only wish I could see the bulge growing and my panties filling up nice and close. But I cant because Im wearing them, but YOU can!
