No, but I have a horrible story to tell. Gather around kids.
I had quite acute diarrhea two years back - could not control it at all. Unfortunately at the time a friend, who I no longer keep in touch with, asked me around to a party. It was in a block of flats and was reasonably enjoyable even though I hardly knew anyone there. It's strangely clear now, I was standing in a corner holding someone else's camera in my hand, and felt very suddenly that I needed to take a dump. I quickly took the picture much to the dissatisfaction of a couple who weren't ready, and asked them if they knew where the toilet was. After finding it occupied, I realised that I wasn't any longer holding it in but was actually pushing.
This is when I knew I had very little time to relieve myself. After a short run, I reached the door to the stairs that is hidden behind a corner. It was just a short run away, but I was not certain that I was going to get there in time. Once I got out, I contemplated my action. My butt hurt badly. I lowered my jeans and boxers and went into a squatting position. It was a quiet, slightly rainy night. I could faintly hear the music from the flat I had just run out of. From my position on the sixth floor, I could overlook the area. No one was there. I just stopped holding it in and the thought of the relief that was to come was only disturbed by the smell of cigarette smoke. It was as if my butt was forced open by a garden hose that was hidden inside it. There was a continuous and heavy downpour for at least ten seconds. There were a few tiny solid pieces that caused pain as they hit my butthole while exiting. I was shaking so much that when I began to pee it would not even flow continuously.
Suddenly, there was a voice: "Did the gutter tear or something?" A second, sounding female, added "my neck is wet." I put my hands on my stomach to increase the pressure to finish as soon as possible when a voice down there said "someone is up there!" A flashlight flashed up from below. I was scared and then the second wave came out of me. Below me, a scream rose through the night: "****, that's ****“. "He's ****ting on us." I could go on but to be honest I think you get the picture. I want to go listen to music, reliving this has been unpleasant. And no, I didn't get caught.
