Testing the Professor: It’s rare for Dr. Piper’s students to visit him at home, but he made an exception for his top student Kacey Lane. While showing him her notes, Kacey caught a stray glimpse of his bulge, and found her thirst for knowledge transformed into a raging desire to get her hands on his big black cock. Rod could tell what she wanted, and offered that college co-ed his hard boner to put in her mouth. After giving him a sloppy blowjob, Kacey bent over against the bookshelves and spread her cheeks open so Rod could lick her flawless asshole. Then he stretched her out with his dick, thrusting into her standing up until she moaned with pleasure.
