"Goooodd God! OOoohh God!!" Betty cried as behind her, Randolph gritted his teeth at the almost unbearably pleasurable sensation of his pretty assistant's cuntal muscled tightly massaging his deeply embedded penis.

The scientist's thick-set body inclined back from the pliant flesh of Miss Johnson's naked buttocks as his probing penis tried to reach the farthest depths of the young woman's totally filled pussy. He did not want to stop until it was completely out of sight, buried so deep up inside the young brunette's hair-lined vaginal opening that his sperm-filled testicles would fit snugly up against her warm flesh. From his excellent position behind the straining twenty-four year old, Randolph shuffled forward just as Betty began to rotate her hips lewdly backward to meet his rigid cock-flesh. Again and again, the kneeling Dr. Randolph thrust up against her wide-held pussy, forcing his rigidly throbbing cock deep into the liquid heat of his young assistant's hungrily contracting vagina.

"Go, go!" he said, deciding that some encouragement was called for. "Go!" The excited professor could not help but think of his wife at a moment like this. Poor Helen with her restricted ideas. This was what sex was all about. It was a test of wills, a sport!

And if this wasn't what it was all about, he, Dr. Adam Randolph was going to find out what was. Maybe one day he would even bring old Helen around to his ideas!

Meanwhile, he was completely satisfied to have had such initial success with the lewdly moaning Miss Johnson.

Dr. Randolph could feel the young assistant's soft cuntal lips clasping tighter and more hungrily around the fleshy intrusion of his desire-hardened cock. She was grinding backward against him letting all the hidden perversity of the moment fill her mind and body.
