While waiting to order my sandwich for lunch, and I began doing the pee pee dance. I really need to go to the bathroom. After a few minutes a guy comes from the back and tells me sorry for the wait, he thought his female co-worker had already started helping me. He prepares and rings up my sandwich. After paying for my food I ask him if I could leave my sub at the counter while I use the restroom. He says sure, and I quickly go to the restroom. I could barely get my panties down and sit on the toilet before my piss started pouring out of my pussy. Someone knocked on the door while I was peeing, but the release felt so good I could not stop. I just had to feel and taste my shit I was so turned on from my very strong poopy smell. Before I left with a naughty grin on my face, I saw the man and told him thank you as I picked up my sandwich on the counter.
