My cock was now achingly erect, and the wondrous sensation of touching Blackie's flesh combined with the ocean water, which came to greet our bodies, served as a natural lubricator. I slowly introduced the top of my engorged member to the puckered little rose of his anus, which he so pleasantly offered up for my pleasure. The feeling of his tight sphincter muscles grasping at my cock enticed me to push forward.

“Oh yes Charlie,” Groaned Blackie, who had started to squirm and writhe under my initial entry.

I took hold of either side of his narrow hips and, gaining leverage, I began to thrust my cock deeper and deeper into his asshole. I felt wonderfully liberated; naked rocking to and fro as I slowly entered Blackie, finally succeeding in getting it in to the hilt. My pubic hair brushed the tender flesh of his ass as it grazed the skin when I pumped my own hips against his. I leaned forward to feel the flesh of his warm muscular back against my own chest and nipples which were painfully erect from the effects of the chilly sea water. I continued to pump faster and faster, and Blackie, to my surprise and delight, was pumping his cock into the well lined hole in the sand!

With every one of my jerks towards his bottom, my cock was rhythmically met with his own thrusts. I arched back and felt the beginnings of a wonderfully explosive pleasure which traveled up from the back of my thighs, tingling and gripping my balls and cock and finally filling my head with intoxicating pleasure. I sped up my thrusts and it seemed as though my cock was fairly being burned by the heat that Gaston's hot little hole was surrounding my member with.

“I'm coming!” I moaned. “Oh Gaston, I am coming!” I gasped and thrust forward once more, shooting my hot white spunk into Blackie's depths. I heard him groan, and felt him stiffen and shudder beneath me as he shot his own come into the earth. I fell forward and embraced my dear friend who had afforded me such great pleasure.
