He does not even look my way or admit my existence. He just unzips and pulls out his monster. As we sit there in awkward silence his cock engorges, getting fully hard, pointing up towards the ceiling. Without saying a word, we both knew the deal, and our respective roles. My mouth was producing drool, lubing itself up, to prepare for his meat. I dropped to my knees and crawled over between his legs. His cock twitched in subtle acknowledgement of my presence, as my lips parted over his enormous mushroom head. He tastes amazing. I start impaling my face on his his cock. Working my way down the shaft. Soon his balls are on my chin and his massive meat was buried in my throat. I am unable to breathe with his cock lodged in my airway, but, I feel his nuts tighten up, preparing to empty their load into me, so I endure a few more moments without oxygen to make sure his pleasure is not interrupted. Just as I was about to pass out, he fills my stomach with hot jizz. His cock shooting load after load into me. I raised my head up so his shots filled my mouth, allowing me to savor the flavor of his cum. I then cleaned his cock with my tongue. 

His thick meat had competently dominated me and used my mouth.

He stood up, tucked that monster away, and walked away without looking at me or saying a word.  I had served my purpose, and was no longer needed.
