I'm an idiot who can't memorize formulas at all. My tutor, who couldn't bear to see me, proposed a novel official memorization method using my breasts and butt! Moreover, if you answer correctly, you will receive a naughty reward! Thanks to you, I can only feel like having fun! Of course, it's extremely effective, and just by remembering the naughty places on your teacher's body, the formula will come to mind! Furthermore, if you get a good score on the test, you will receive an extremely erotic bonus...! My grades are improving rapidly and my erotic deviation value is also skyrocketing! This memorization method is the best!
