I'm giving it a working title of The Big Tit Blowjob Mountain. It's kind of a cross between Misery and your average teen/young adult sex farce. It's about this crazy spinster cat lady that lures people from the internet to come visit her for free sex in her bungalow in the middle of what she calls the Big Tit Blowjob Mountains of Minnesoter. Think of it as one story that you get to see two sides of: The crazy lady and the current victim she is targeting. As the story moves forward, Saw-like flashbacks will be used to tell her past history, which includes murdering someone she lured from Swissyland and eating his entrails, believing them to contain the last of the chocolate she kept in the house.
Actually, maybe the feds could be tracking her down due to the disappearance of the man from Swissyland, and that could be the device used to reveal her past history. Then the movie could end with the feds busting into her place just as she's killing her latest victim. Maybe we can rip off SIlence of the Lambs in that scene.
I can come up with more details, like the story of her current victim. Maybe her current victim could be G, who lied himself into being a real casanova. That way, not only would her scheme backfire, but she'd be murdered by feds soonafter, making for a really shitty day.
