back, and slowly started to keel over.

Having stood in one spot in the mud so long, he couldn't move his feet. Realizing what was going to happen, I wrapped my arms around his ass and followed him down into the mud. He hit with a huge splash, and as he started to sink into it, I took a huge breath though my nose, and went under, his cock still firmly in my mouth. I felt him give me two more squirts of hot liquid before I had to go back up for air, but I kept stroking his meat with my hand until he begged me to stop. He lay there gasping for breath as I wiped the mud out of my eyes and off my face. Then he rolled towards me, grabbed my arm and said, "If I could possibly get it up again I'd fuck your ass right here"

Which is exactly what we did two nights later - but that's another story!
