Mark Wood comes home to find babysitter Tia Cyrus having problems with her school work. Tia is a great babysitter and Mark gladly offers to help her. She explains that she can’t quite grasp the mathematical concept of fractions. Mark offers to demonstrate the abstract concept using a real-world object: his cock.
Tia has her doubts about this teaching method but once she sees Mark’s cock her doubts disappear. Mark tells Tia to swallow one third, then two quarters of cock and finally she understands fractions. She also knows that sucking cock isn’t enough and Tia gets her pussy some learning as well.
