His hard cock was sliding full length
into my throat now.  My throat
opened willing and accepted every inch of his fat cock. The man moaned as he felt
my throat for the first time. His cock pulsing with approval and an eagerness to get deeper.  Knowing now
that my throat was opened for him he settled into a slow but relentless fucking
motion.  He had a firm grip on my head as he fed me his cock.  

My mind slowly shut down until it focused on nothing but the meat stretching out my throat.  All the doubts of following a stranger into the dirty motel room and letting him use me, went away. I had found my place. My
body no longer resisted his assault.  I was open to him. He could now use my mouth to jerk off with as hard as he wanted.  I could feel myself ceasing to be a man and becoming the object he needed me to be. A hole to be used to stroke his cock.  A warm, wet place to dump his load. It felt right.
