Do you have the tape Karen?" Rub it faster please Susan, get that clitoris fully erect for us all. Now class, you will notice the inner labia have also swollen and started to separate ready for penetration. The clitoris is now fully engorged too. The slow movement in our subjects hips and her moans tells me that she is enjoying Susan’s manual administrations.”A male voice shouted from quite far away saying that he couldn't see Kathy's pussy clearly, and after a short pause, the professor cleared his throat before adding, "Right everyone come down here and stand around the subject, you will then all get a bird's eye view."

This time put on some gloves."Faster Justin, we need to see how much you heart rate goes up." Karen sounded delighted to be the instrument of my humiliation. Beth, it's important to watch Justin carefully." The doctor added. "We look for any signs that he is imbalanced or that he might be getting dizzy, so please look at him and Justin please put your chin up and look straight ahead. We need to see your face."
