Forget the specific is the second or third year of high school, I sit in front of the girl is considered more beautiful type, the chest is not very big (in fact, still a little material, later have the opportunity to say, afraid to say too much was found to be miserable), but the butt is very big but because that time are wearing school pants also do not feel warped is big. The desks at school are not very wide, and our chairs are backrest but the backrest is empty below. She used to hang her schoolbag on the backrest, I have a habit of sitting very close to the table in class, and then both legs have been moving around, but she has been touching her schoolbag, her schoolbag is also very soft kind. So there is a class I moved a long time, at first has not been much feeling, until answering a question stand up only to find that she did not hang up the book bag today, but a little lying on the table butt convex in the back. I that crazy dizzy ah, the original has been touching is her ass, but at that time the timid or do not know what is going on, afraid that she found it did not dare, in fact, now think really stupid, completely can fuck to her big ass. When I think back on the previous events, there were actually many opportunities lost.
