Today, while at work, I was getting the feeling that I was really going to have to take a big shit. So I waited, then ate a good sized lunch, and went back to work. I work in rental units and was doing a job in an empty house, getting things ready, so I knew nobody would be around. I was really starting to have a hard time holding it in when I decided it would be cool to have an accident at work. So I took a rag from my truck and lined it with 2 paper towels. I then used that to pad my underwear and pulled my jeans back up over that. After about an hour I was getting to the point where my next cramp and clench would be the last and it would all come out. So I relaxed a little, felt a wave hit and tried to hold, but my body knew it was time to let go so I lost all control and it just slowly came out in a sort of shit flow into my jeans. The load was enormous and quickly filled up the entire seat of my jeans and underwear. It was relatively soft and made a mess of my ass cheeks and balls, it felt nice and warm. I stood there moving my legs back and forth letting it squeeze between them and my ass. I was hard instantly and jerked off. I emptied my mess into the toilet and threw out the towel. Cleaned myself up in the bathroom and got back to work. This whole thing felt amazing and was exciting since I have never had this happen at work before.
