My younger sister (a high school girl) asked me to borrow my video camera on the day of her sleepover, so I lent it to her, and it recorded more than I expected! My sisters invited not only their female friends but also their male friends over to our house, and since there were no adults around, they let loose and had a blast! Naturally, when a bunch of men and women of that age who are interested in sex get together, it's inevitable that something will happen... they just keep on fucking! It was a parade of dirty footage that would put any adult video to shame, so I decided to turn it into an adult video without permission! Sorry, sister!
