Good, they should get extra for moving, rubbing there ass, in reality it would be done over the school panties and they would not be stripped nude like in a lot of videos, but I know you know that lol.
Yes very easy for him to have folded back, so why he was such a dumb cunt is anyone's guess, this naughty slut should of got extra whacks for rubbing her ass wouldn't you agree.
Yews, it seems a little futile. If it was pulled up over her back, not only would he be able to continue without fiddling with it but we would get a much clearer view.
