Mandy Moon Compares a Parabola to Her Tutor's Big Dick

Mandy Moon is a brunette student struggling with math, so she signs up for extra lessons to catch up on her studying program. She tries to stay focused on parabolas, but her mind keeps drifting toward dicks instead of equations, and she can barely sit still through the lesson. Her teacher notices she needs a different kind of motivation to be a diligent student, so he decides to use the moment for his own fun. He pulls his big dick out of his pants and tells Mandy to compare its curve to the parabola on the page. The role play quickly turns into a hands-on blowjob lesson, with Mandy trading her textbook for a much more practical study session.
