Sounded medium to firm to hard mud can easily be palpated through the underside of my cock shaft. There is no problem determining where each piece starts and ends. The presence of pre-ejaculatory fluid emitted from the urethra aids to working the firm and hard mud into a more fluid state. Where a steel or silicone sound just sits where its inserted and extends from the penis, the mud is wholly contained and as each mass softens and dissolves, the palpated change in size can easily be realized. I found that once all the sounded mud can no longer be felt, I can sound more and continue. The action of massaging the sounded mud does not bring me to orgasm, it is not even close to edging, but it is a unique thrill to feel each mass vanish from my perceptions.

Everything I sounded a few hours ago is now gone, at least I can no longer feel the mud. Time to sound some more...
