"Mmmmmm," Betty begged, squirming her ass-cheeks backward to meet Dr. Randolph's madly licking tongue. "Mmmmmmm!" she repeated as the scientist changed his position so that he had an even better vantage point between the twenty-four year old's quivering white thighs. At the same time, he parted Betty's legs as he attached his mouth to the wide open split of the young woman's streaming pussy and began to suck upon the passion-drenched pinkness of her inner flesh with new enthusiasm.

"Ooooohhhh!"

Suddenly, she felt Dr. Randolph's hands creeping up to her waist and then clasping her heavily swaying breasts. His fingers began to play through the material of her lab smock, feeling the pebble hardness of the assistant's fully erected nipples. With a little squeal that signaled her surrender, Betty abandoned herself to the sudden rushes of pleasure as the fingers that were so familiar to her in the laboratory or during a class tantalized her erotically tingling breasts. And now, down between her widespread, trembling thighs, her desire-inflamed cunt felt like a hot, glowing coal that would reach greater and greater heights of lust the longer the forbidden sucking continued.

"Mmmm! Mmmm?" Randolph murmured inquiringly into Betty's succulent young cunt. This was the best idea he'd had in years! He would remember each and every detail for recording in his notebook, for this auspicious evening marked the very first experiment of the work that would soon make him famous.

"Going to put it to you! Gonna give it to you! Mmmm? Mmmm!" he declared, raising his glistening wet face. The ardent researcher's jowled cheeks reflected the excitement he was feeling as he quickly opened his zipper fly and withdrew his thickly pulsing cock. It felt rock-hard in his steady hands, and he could hardly wait. Before him was the submissively kneeling figure of his lab assistant. He took in the lewd image of the young woman's nakedly exposed buttocks, of her glistening wet cuntal hair that pouted in a small triangle below. She was just ready and waiting for his long, hard cock. And he was really going to take her right then and there!
