Huge fetish for upskirt pictures

I've known for the past few months that I loved upskirt videos, not cause it was more interesting than porn or anything, but because the girl doesn't know, and I can also try doing it. One day in a class, unnoticed that one of the cute girls was wearing a skirt, so I realized this is my perfect opportunity. I went home, got my spy camera and everything, and decided that I am going to sneak it under her desk before the class starts, because I'm always the first one there.
