Jason X got into the taxi today and asked me to drive him to to Charles University. I had actually studied at the same school some years earlier, so we got to chatting about it. Jason had an anatomy exam, and was having trouble remembering the Latin names for body parts. I had studied nursing, and was quite good at that subject, so I told him I would quiz him. I got into the backseat and quizzed him on the word for breasts, then took out my boobs. Next was the bum, and last was the pussy. Finally, I asked him if he knew the word for penis, then put his cock in my mouth! All this scientific talk made me very wet, and I rode Jason's glistening cock until he came on my pussy!
