一个漂亮的学生被一个研究员和他的司机接走,进行性研究
A stunning young woman, eager to participate in a research study, eagerly hops into the car of a kindly professor and his driver. The professor, intrigued by her beauty, decides to add a bit of excitement to the study by exploring her sexual desires. As the driver watches, the professor's throbbing member finds its way into the girl's mouth, eliciting moans of pleasure. But the professor doesn't want to stop there. He instructs the driver to join in, and soon the girl is being pleasured by two men at once. The professor takes her from behind while the driver takes her from the front. The girl, overwhelmed by the sensation, can only moan in ecstasy. The professor then takes her on the couch, where he removes her shorts and spreads her legs, plunging his member deep inside her. The girl, now fully satisfied, is left naked on the couch as the professor and driver discuss their findings.
