No matter how much I study with my childhood friend, my academic ability never improves. I feel depressed and frustrated by my own lack of ability. To cheer me up, my childhood friend shows up in a ridiculously provocative outfit: no panties and garter stockings! It certainly cheers me up, but on the other hand, it makes it impossible for me to study! Because her pussy is visible! There's no way I can study like that! I'm so embarrassed...
