You mean raping them? I don't think those exist because it doesn't happen in real life. Don't get me wrong, I think men get raped just as often as women do except we don't call it getting raped, we call it getting laid.
you might be searching for videos such as manhunters.com.. or girl riders.. where its the same thing as milf hunters except girls are hunting guys.. and the other one is where girls are in a van or something and hunt for guy hitch hikers. and force them into sex -
