Family Strokes - Solve For The Variable, XXX

Our stud is having trouble with his math classes. He can change oil, but he cannot seem to figure out whether x is a number or a letter! Luckily, he talks to a guy whose stepdaughter, Ava Haze, is a real math whiz. Ava is willing to help this dummy out, and tries to explain what an algebraic equation is, but it is like trying to beat a dead horse with a sledgehammer. Our stud has his head so far up his own ass that he cannot even concentrate unless he busts a nut! What a Neanderthal! Ava is fed up, but as a tutor, she understands that she needs to adapt to her students needs. She helps him out by making him feel a little more comfortable while he masturbates on the couch. She plays with her pussy and watches him stroke his long ruler. Then he adds his cock to her pussy, and the good times grow exponentially. He sticks his long inequality inside her and works through all the calculations with ease. She loves every inch and rides him up and down, showing him all the possible values that a variable can have. Finally, she takes his derivative on her chin and is totally satisfied. This seems like how math should always be taught, doesnt it?
