A few days ago, I set up a predicament in my mud pit. The picture describes it better than I can with words. The idea was that I was partially suspended by my genitals. The mud wasn't deep enough for me to be in any danger. The attached image is a frame from the video recording.
Since I did this scene, I stirred up the mud in that pit so it's much more fluid, now. I might just have to do it all again.
