sometimes when i leave the house, I will wear an adult diaper, I will go to a department store, walk around for a bit til I really have to go to the bathroom, then I will wait til the time is just right and I will poop in the diaper on purpose and keep walking around the store like nothings wrong, just feeling the poop in the diaper as I walk around gives me a boner, its even better with the diaper full of pee too.
there was one time I went to the store with out the diaper, and oh man I really had to pee, so I peed my pants right there, I had a big wet spot running down the front of my jeans
