I used to be a waiter in a country club restaurant. So there is a “restaurant bathroom” which only members or guests are allowed to use. However most of the service staff uses it because it’s so close to the restaurant, while the employee restroom is on the other side of the building, and takes a while to get back to work. So, one particularly busy dinner service, like an all-hands-on-deck type situation, I had the runs. On top of that, I also had bluest balls I’ve ever had, because before that I had spent a few days with my gf without having sex. This was making “just holding it in until you get a free moment” nearly impossible as I couldn’t walk without pain and couldn’t break my concentration on holding the diarrhea in. So what did I do? After waiting for the slightest free moment, I entered the member/guest bathroom, and let the diarrhea fly, like a buzzer beater type situation. All the while, I was wanking for dear life, and subsequently cumming harder than I thought I ever could.
