Despite herself, Betty couldn't help wondering just what he would do next. But whatever she had expected, it was not what happened, for suddenly she heard her professor moan hungrily, and then she felt him drop down behind her nakedly offered buttocks. The next thing, the dark-haired graduate student felt was his heated breath and then a thrilling wetness back between her spread thighs. Dr. Randolph was tonguing her from behind, sticking the quivering tip of his tongue deep into the wetly throbbing lips of her pussy and licking lewdly within her sensitive layers of cuntal flesh.

"Oooooh!" The dark channel of Betty's hair-trimmed pussy began to twitch in heated arousal. No one had ever done such a thing to her. Could she? she wondered. Could she actually enjoy such an obscene act? Her nakedly exposed buttocks were oddly still as Betty's humiliation turned into a blatant carnal excitement. It was a stirring deep in her loins as well as in her mind as wicked tingles of pleasure wove in and out of the pores of the sensitive flesh up between her legs. The gentle stroking of her attacker's tongue made her feel totally wanton, totally free in a way she had never dreamed was possible! Her very position, half naked with her panties halfway down, kneeling on the floor of the lab like this, brought a greater excitement, and the pretty young assistant felt all control slipping away. All thought was mercifully blotted from her mind, whereas with her boyfriend, all she did was think, think, think through the whole thing. This was something wildly different, though, and she was a writhing mass of feminine sensuality, created for loving, and nothing more or less.
