Tina could suck the proverbial golf ball from a garden hose, Chris thought inanely as sparks coursed through his body.  She was simply the best and he continued to thrust his cock into her receptive mouth and against her throat.  Chris wasn't certain why but he felt freer than he had in years having this lovely nurse going down on him.  It was a good feeling and he planned on enjoying this as much as he could  "Baby, I'm going to come soon."  He grunted as his thrusting quickened paying no attention to Tina's comfort, only his satisfaction mattered now.
