There was this film I saw some years ago to which only the other day I started remembering about it especially a couple scenes it happens about two thirds of the way into it there is this really fat overweight guy who looks to like in his late 50's early 60's only see him in it a few times, he's always chatting to these teenaged high school girls (looked to have been about 14 to 15 years old) the main one of which was the little blonde girl who was always in pigtails and wearing a blue/black Plaid Skirt and the main scenes of which I remember the most is first, you see him meeting up with the group on their way home after school (if i remember I think his character knew hers from him knowing her dad or that they worked together and were Neighbours?, some like that but they did know each other)
I think he was purposefully waiting for her and then they walk together for a time and then they say goodbye to the rest of the others girls then it cuts to black before another scene to another part of the film and then about ten fifteen minutes later it cuts back to them around the back of building to where it pans over to her bag, shoes, top, blouse and bra lying on the ground a few feet away from them to it moving towards the soles of her feet then slowly moving up the back then to the side of her body before it get's to her head moving back and forth and to hearing slurping and sucking noises to his hands on either side of her head and to hear him grunting and panting heavily, there were a few other scenes of them together one in the woods and then another of them in this abandoned car in some industrial area.
I also remember that this film also had quite a few famous faces in it but those names now have completely slipped my mind, it wasn't a particular famous film but it have some notoriety.
if anyone can help me in finding out what the hell this film was called again I'd very much be truly grateful
