British bimbo Barbie Sins does some extra credit oral exams

She may have been the best performing student in her class, but she was determined to show she had more under her sleeve. Professor Danny D wasn't sure what she had in mind since he couldn't give her any higher grades, but he soon got the memo when Barbie Sins went down on his cock and spread her legs afterwards. He was so pleased he gave her an "excellent" mark all over her glasses and face.
