She was keenly aware of her vulnerability and didn't want to give herself away to her captor.From behind one way glass, four of Kelly's prettier cowor...ers watched her struggle and twist, seeing the fear in her eyes. She had been brought into the company's equipment prototype testing department unconscious and placed on a positionable cart designed for testing equipments' effect on different parts of a car's paneling. She had been placed on her back with all of her holes fully exposed and this. I stopped doing this exercise because almost the instant a student’s hands touched my cock, it would get hard. And then it wouldn’t go down so the next person could try. Everybody thought this was pretty funny. And further complicating this experiment was that several students took the opportunity to quickly pop my flaccid prick in their mouth and start sucking even though that was against my rules. So I had to put a stop to the contest. Another aspect of the class that I would like to have. And being a virgin, I was just being a good boy and watching. When she was done, it was still raining pretty bad, she started to kiss me again. This time I was touching her body, but not her parts, she would take my hands off if I tried anything. On the other side, she was passing her hand all over my cock over my pants. I don't remember ever being that hard. We stayed there like that for 15 minutes or so, but the rain had stopped. So at that time she decided it was time to go, she removed her. It took a minute or two but I felt the tip slip into Linda, and she moaned deeply. “Oh it hurts, but it hurts so good!” she softly moaned, and pushed herself back against me. I pulled out slightly then pushed back in, feeling more of my cock slide into her ass. She was almost painfully tight, and hot around me. It took several minutes, but finally I was deep inside of her, holding myself still for a moment, then I started to fuck her ass.Her moans were getting louder, and the low deep grunts.
