A Perverted Student Uses Sex to Bribe Her Teacher for Better Grades

The student is a real dud. She needs better grades, but math still eludes her. So she decides to do something she's better at. She seduces the teacher and films the whole thing. Afterward, she has something to blackmail him with, since he's married. But if he decides to sleep with the petite, small-breasted girl, he shouldn't be surprised. The babe, at least, has her fun.
