A week after my first undertaking in my new mud pit I went back and this time I wanted to see how deep it really was. I followed the same procedure going to it as before. I didn't anticipate being seen entering the park but better to err on the side of caution. I took my clothes off and stepped in, it was a little wetter from sporadic rain over the passed week but still plenty thick. My legs disappeared into the sucking mud as I worked my way towards the middle of the pit. Being in mud is very stimulating sexually for me so I was again fully aroused as the mud swallowed my hips and waist. I resisted the urge to take care of business and kept struggling forward. I was solidly chest deep as I finally reached the center and I could feel that I could go deeper but I was out of breath from the exertion and just relaxed for a few minutes. The mud settled firmly around me just like before and the sensation of being captured by it made my naked body tingle from head to toe. I had my arms down next to me and by the time I was ready to move again I had to make some wiggle room to go deeper. I pointed my toes straight down and started lifting with my arms and went in another few inches, bringing the mud up even to my shoulders. Unfortunately, the next push to go deeper didn't go as well. I sank in and the mud was brushing around the bottom of my neck but my toes ran right into a semi solid layer that I couldn't get through. Needless to say I could have easily submerged by bending my legs but I'm not big on submersion so I didn't try to force the issue. I let myself stay in the mud's grasp until honestly I just couldn't resist the need to get a load off, but being encased as I was I had to work my way free a bit first. 15-20 minutes later...I had to rest again but I'd escaped the center of the pit and was about waist deep. My body was on fire and my throbbing erection begged for release and it must have taken less than a minute for me to cum, but damn it felt unbelievable. Getting all the way out was pretty easy this time but clean up took a bit longer since I had alot of mud clinging to my body and plus I had been dripping with sweat and I needed to cool down in more ways than one. Getting my clothes back on and starting to walk home however, I suddenly realised how sore my legs were and I was exhausted by the time I made it. I'm pretty sure I dozed off standing in the shower a couple times and I didn't even bother getting my sleeping shorts on before I fell into bed.
