Closing his eyes he pulled back and plunged in again, grabbing her hips to help him thrust. In a few seconds he was completely buried in her, the firm round cheeks of her ass pressed against his belly. Frantically he pulled his shirt aside so he could feel her flesh on his. Then he began sawing in and out of her with great, driving strokes, overwhelmed by the tightness and the heat and the strength with which Susie clamped her ass muscles down on him, but even more so by the very idea of what he was doing.

Susie squirmed back in ecstasy, loving the feeling of that long rod slicing into her, clenching and squeezing her ass muscles, gasping in delight as he drove into her over and over again. It was so good. It was always so good when she had a cock in her, no matter where. She came with a series of small explosions that made her asshole clutch convulsively at the cock that filled it. Cummings was so incredibly excited, and Susie's ass was much too tight, for him to last long, and in less than two minutes he collapsed panting onto her back. His weight pressed her titties cruelly against his desk as his cock throbbed and squirted its load deep into her bowels. Susie moaned and came again as she felt him shoot, then she gently squeezed his shrinking cock in gratitude.

When he finally recovered and pulled away, Cummings looked down at the fragile body still spread over his desk, at the round swell of her girlish ass, at his own stained and streaked cock. He couldn't believe it; it couldn't have happened. But he was even more shocked and incredulous when the young girl turned around and smiled happily up at him, reaching out for his now limp prick. Then she fell to her knees in front of him and kissed the head of his cock.

"Now I want to taste it, Mr. Cummings. That was so good. Your cock fit so nice in my behind. But it got all dirty there, so I'm going to clean it off."

"Shit, girl! You can't! What the fuck? It's… that's filthy!"
