Sadly this isn't a real movie, but it is a pretty awesome parody of Cabin in the woods that looks at shit handjob techniques. Handjob Cabin follows a bunch of teens as they go away for the weekend. But they soon discover that their holiday cabin is haunted by the ghost of a teenage girl who died during a wank-off session with a guy. Why can't this be a real film? It'd be way better than the pile of pap that was Cabin in the woods.
