One curious and smart girl Patty liked anatomy a lot. Human body is a very interesting thing, especially brunette babe was interested in men's body. So one day she came to her teacher and asked him to tell something interesting about cock. The old pervert decided that it will be more useful not only to tell Patty about how the dick works, but to show her everything and teach her how to make every guy happy using her body. Teen Patty was happy when her professor took out his rod and let her play with it for hours. Then he fucked her and spilled tons of hot jizz on Patty's tight butt.
